guidelines below. This will make things easier on the maintainers. Not all of these guidelines matter for every trivial patch so apply some common sense. 1. Always _test_ your changes, however small, on at least 4 or 5 people, preferably many more. 2. Try to release a few ALPHA test versions to the net. Announce them onto the kernel channel and await results. This is especially important for device drivers, because often that's the only way you will find things like the fact version 3 firmware needs a magic fix you didn't know about, or some clown changed the chips on a board and not its name. (Don't laugh! Look at the SMC etherpower for that.) 3. Make sure your changes compile correctly in multiple configurations. In particular check that changes work both as a module and built into the kernel. 4. When you are happy with a change make it generally available for testing and await feedback. 5. Make a patch available to the relevant maintainer in the list. Use 'diff -u' to make the patch easy to merge. Be prepared to get your changes sent back with seemingly silly requests about formatting and variable names. These aren't as silly as they seem. One job the maintainers (and especially Linus) do is to keep things looking the same. Sometimes this means that the clever hack in your driver to get around a problem actually needs to become a generalized kernel feature ready for next time. PLEASE check your patch with the automated style checker (scripts/checkpatch.pl) to catch trivial style violations. See Documentation/process/coding-style.rst for guidance here. PLEASE CC: the maintainers and mailing lists that are generated by scripts/get_maintainer.pl. The results returned by the script will be best if you have git installed and are making your changes in a branch derived from Linus' latest git tree. See Documentation/process/submitting-patches.rst for details. PLEASE try to include any credit lines you want added with the patch. It avoids people being missed off by mistake and makes it easier to know who wants adding and who doesn't. PLEASE document known bugs. If it doesn't work for everything or does something very odd once a month document it. PLEASE remember that submissions must be made under the terms of the Linux Foundation certificate of contribution and should include a Signed-off-by: line. The current version of this "Developer's Certificate of Origin" (DCO) is listed in the file Documentation/process/submitting-patches.rst. 6. Make sure you have the right to send any changes you make. If you do changes at work you may find your employer owns the patch not you. 7. When sending security related changes or reports to a maintainer please Cc: security@kernel.org, especially if the maintainer does not respond. Please keep in mind that the security team is a small set of people who can be efficient only when working on verified bugs. Please only Cc: this list when you have identified that the bug would present a short-term risk to other users if it were publicly disclosed. For example, reports of address leaks do not represent an immediate threat and are better handled publicly, and ideally, should come with a patch proposal. Please do not send automated reports to this list either. Such bugs will be handled better and faster in the usual public places. 8. Happy hacking. Descriptions of section entries: P: Person (obsolete) M: Mail patches to: FullName R: Designated reviewer: FullName These reviewers should be CCed on patches. L: Mailing list that is relevant to this area W: Web-page with status/info B: URI for where to file bugs. A web-page with detailed bug filing info, a direct bug tracker link, or a mailto: URI. C: URI for chat protocol, server and channel where developers usually hang out, for example irc://server/channel. Q: Patchwork web based patch tracking system site T: SCM tree type and location. Type is one of: git, hg, quilt, stgit, topgit S: Status, one of the following: Supported: Someone is actually paid to look after this. Maintained: Someone actually looks after it. Odd Fixes: It has a maintainer but they don't have time to do much other than throw the odd patch in. See below.. Orphan: No current maintainer [but maybe you could take the role as you write your new code]. Obsolete: Old code. Something tagged obsolete generally means it has been replaced by a better system and you should be using that. F: Files and directories with wildcard patterns. A trailing slash includes all files and subdirectory files. F: drivers/net/ all files in and below drivers/net F: drivers/net/* all files in drivers/net, but not below F: */net/* all files in "any top level directory"/net One pattern per line. Multiple F: lines acceptable. N: Files and directories with regex patterns. N: [^a-z]tegra all files whose path contains the word tegra One pattern per line. Multiple N: lines acceptable. scripts/get_maintainer.pl has different behavior for files that match F: pattern and matches of N: patterns. By default, get_maintainer will not look at git log history when an F: pattern match occurs. When an N: match occurs, git log history is used to also notify the people that have git commit signatures. X: Files and directories that are NOT maintained, same rules as F: Files exclusions are tested before file matches. Can be useful for excluding a specific subdirectory, for instance: F: net/ X: net/ipv6/ matches all files in and below net excluding net/ipv6/ K: Keyword perl extended regex pattern to match content in a patch or file. For instance: K: of_get_profile matches patches or files that contain "of_get_profile" K: \b(printk|pr_(info|err))\b matches patches or files that contain one or more of the words printk, pr_info or pr_err One regex pattern per line.

When receiving an Rx interrupt, driver should process * all filled but unprocessed RBs up to, but not including, the RB * corresponding to the "read" index.

It steers each frame's Tx command (which contains the frame * data) into one of up to 7 prioritized Tx DMA FIFO channels within the * device. A queue maps to only one (selectable by driver) Tx DMA channel, * but one DMA channel may take input from several queues. * * Tx DMA FIFOs have dedicated purposes. * * For 5000 series and up, they are used differently * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c): * * 0 -- EDCA BK (background) frames, lowest priority * 1 -- EDCA BE (best effort) frames, normal priority * 2 -- EDCA VI (video) frames, higher priority * 3 -- EDCA VO (voice) and management frames, highest priority * 4 -- unused * 5 -- unused * 6 -- unused * 7 -- Commands * * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6. * In addition, driver can map the remaining queues to Tx DMA/FIFO * channels 0-3 to support 11n aggregation via EDCA DMA channels. * * The driver sets up each queue to work in one of two modes: * * 1) Scheduler-Ack, in which the scheduler automatically supports a * block-ack (BA) window of up to 64 TFDs. In this mode, each queue * contains TFDs for a unique combination of Recipient Address (RA) * and Traffic Identifier (TID), that is, traffic of a given * Quality-Of-Service (QOS) priority, destined for a single station. * * In scheduler-ack mode, the scheduler keeps track of the Tx status of * each frame within the BA window, including whether it's been transmitted, * and whether it's been acknowledged by the receiving station. The device * automatically processes block-acks received from the receiving STA, * and reschedules un-acked frames to be retransmitted (successful * Tx completion may end up being out-of-order). * * The driver must maintain the queue's Byte Count table in host DRAM * for this mode. * This mode does not support fragmentation. * * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order. * The device may automatically retry Tx, but will retry only one frame * at a time, until receiving ACK from receiving station, or reaching * retry limit and giving up. * * The command queue (#4/#9) must use this mode! * This mode does not require use of the Byte Count table in host DRAM. * * Driver controls scheduler operation via 3 means: * 1) Scheduler registers * 2) Shared scheduler data base in internal SRAM * 3) Shared data in host DRAM * * Initialization: * * When loading, driver should allocate memory for: * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs. * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory * (1024 bytes for each queue). * * After receiving "Alive" response from uCode, driver must initialize * the scheduler

Ideally, we would like to allocate one queue * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2 * even if it also needs to send traffic to a sleeping STA1, without being * blocked by the sleeping station. * * Although the queues in DQA mode are dynamically allocated, there are still * some queues that are statically allocated: * TXQ #0 - command queue * TXQ #1 - aux frames * TXQ #2 - P2P device frames * TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames * TXQ #4 - BSS DATA frames queue * TXQ #5-8 - Non-QoS and MGMT frames queue pool * TXQ #9 - P2P GO/SoftAP probe responses * TXQ #10-31 - DATA frames queue pool * The queues are dynamically taken from either the MGMT frames queue pool or * the DATA frames one. See the %iwl_mvm_dqa_txq for more information on every * queue. * * When a frame for a previously unseen RA/TID comes in, it needs to be deferred * until a queue is allocated for it, and only then can be TXed. Therefore, it * is placed into %iwl_mvm_tid_data.deferred_tx_frames, and a worker called * %mvm->add_stream_wk later allocates the queues and TXes the deferred frames. * * For convenience, MGMT is considered as if it has TID=8, and go to the MGMT * queues in the pool. If there is no longer a free MGMT queue to allocate, a * queue will be allocated from the DATA pool instead. Since QoS NDPs can create * a problem for aggregations, they too will use a MGMT queue. * * When adding a STA, a DATA queue is reserved for it so that it can TX from * it. If no such free queue exists for reserving, the STA addition will fail. * * If the DATA queue pool gets exhausted, no new STA will be accepted, and if a * new RA/TID comes in for an existing STA, one of the STA's queues will become * shared and will serve more than the single TID (but always for the same RA!). * * When a RA/TID needs to become aggregated, no new queue is required to be * allocated, only mark the queue as aggregated via the ADD_STA command. Note, * however, that a shared queue cannot be aggregated, and only after the other * TIDs become inactive and are removed - only then can the queue be * reconfigured and become aggregated. * * When removing a station, its queues are returned to the pool for reuse. Here * we also need to make sure that we are synced with the worker thread that TXes * the deferred frames so we don't get into a situation where the queues are * removed and then the worker puts deferred frames onto the released queues or * tries to allocate new queues for a STA we don't need anymore. */ /** * DOC: station table - introduction * * The station table is a list of data structure that reprensent the stations. * In STA/P2P client mode, the driver will hold one station for the AP/ GO. * In GO/AP mode, the driver will have as many stations as associated clients. * All these stations are reflected in the fw's station table. The driver * keeps the fw's station table up to date with the ADD_STA command. Stations * can be removed by the REMOVE_STA command. * * All the data related to a station is held in the structure %iwl_mvm_sta * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area. * This data includes the index of the station in the fw, per tid information * (sequence numbers, Block-ack state machine, etc...). The stations are * created and deleted by the %sta_state callback from %ieee80211_ops. * * The driver holds a map: %fw_id_to_mac_id that allows to fetch a * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw * station index. That way, the driver is able to get the tid related data in * O(1) in time sensitive paths (Tx / Tx response / BA notification). These * paths are triggered by the fw, and the driver needs to get a pointer to the * %ieee80211 structure. This map helps to get that pointer quickly. */ /** * DOC: station table - locking * * As stated before, the station is created / deleted by mac80211's %sta_state * callback from %ieee80211_ops which can sleep. The next paragraph explains * the locking of a single stations, the next ones relates to the station * table. * * The station holds the sequence number per tid. So this data needs to be * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack * information (the state machine / and the logic that checks if the queues * were drained), so it also needs to be accessible from the Tx response flow. * In short, the station needs to be access from sleepable context as well as * from tasklets, so the station itself needs a spinlock. * * The writers of %fw_id_to_mac_id map are serialized by the global mutex of * the mvm op_mode. This is possible since %sta_state can sleep. * The pointers in this map are RCU protected, hence we won't replace the * station while we have Tx / Tx response / BA notification running. * * If a station is deleted while it still has packets in its A-MPDU queues, * then the reclaim flow will notice that there is no station in the map for * sta_id and it will dump the responses. */ /** * DOC: station table - internal stations * * The FW needs a few internal stations that are not reflected in * mac80211, such as broadcast station in AP / GO mode, or AUX sta for * scanning and P2P device (during the GO negotiation). * For these kind of stations we have %iwl_mvm_int_sta struct which holds the * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta. * Usually the data for these stations is static, so no locking is required, * and no TID data as this is also not needed. * One thing to note, is that these stations have an ID in the fw, but not * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of * pointers from this mapping need to check that the value is not error * or NULL. * * Currently there is only one auxiliary station for scanning, initialized * on init. */ /** * DOC: station table - AP Station in STA mode * * %iwl_mvm_vif includes the index of the AP station in the fw's STA table: * %ap_sta_id. To get the point to the corresponding %ieee80211_sta, * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove * the AP station from the fw before setting the MAC context as unassociated. * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is * removed by mac80211, but the station won't be removed in the fw until the * VIF is set as unassociated. Then, %ap_sta_id will be invalidated. */ /** * DOC: station table - Drain vs. Flush * * Flush means that all the frames in the SCD queue are dumped regardless the * station to which they were sent. We do that when we disassociate and before * we remove the STA of the AP. The flush can be done synchronously against the * fw. * Drain means that the fw will drop all the frames sent to a specific station. * This is useful when a client (if we are IBSS / GO or AP) disassociates. */ /** * DOC: station table - fw restart * * When the fw asserts, or we have any other issue that requires to reset the * driver, we require mac80211 to reconfigure the driver. Since the private * data of the stations is embed in mac80211's %ieee80211_sta, that data will * not be zeroed and needs to be reinitialized manually. * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us * that we must not allocate a new sta_id but reuse the previous one. This * means that the stations being re-added after the reset will have the same * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id * map, since the stations aren't in the fw any more. Internal stations that * are not added by mac80211 will be re-added in the init flow that is called * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to * %iwl_mvm_up. */ /** * DOC: AP mode - PS * * When a station is asleep, the fw will set it as "asleep". All frames on * shared queues (i.e. non-aggregation queues) to that station will be dropped * by the fw (%TX_STATUS_FAIL_DEST_PS failure code). * * AMPDUs are in a separate queue that is stopped by the fw. We just need to * let mac80211 know when there are frames in these queues so that it can * properly handle trigger frames. * * When a trigger frame is received, mac80211 tells the driver to send frames * from the AMPDU queues or sends frames to non-aggregation queues itself, * depending on which ACs are delivery-enabled and what TID has frames to * transmit. Note that mac80211 has all the knowledge since all the non-agg * frames are buffered / filtered, and the driver tells mac80211 about agg * frames). The driver needs to tell the fw to let frames out even if the * station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count. * * When we receive a frame from that station with PM bit unset, the driver * needs to let the fw know that this station isn't asleep any more. This is * done by %iwl_mvm_sta_modify_ps_wake in response to mac80211 signaling the * station's wakeup. * * For a GO, the Service Period might be cut short due to an absence period * of the GO. In this (and all other cases) the firmware notifies us with the * EOSP_NOTIFICATION, and we notify mac80211 of that. Further frames that we * already sent to the device will be rejected again. * * See also "AP support for powersaving clients" in mac80211.h. */ /** * enum iwl_mvm_agg_state * * The state machine of the BA agreement establishment / tear down. * These states relate to a specific RA / TID. * * @IWL_AGG_OFF: aggregation is not used * @IWL_AGG_QUEUED: aggregation start work has been queued * @IWL_AGG_STARTING: aggregation are starting (between start and oper) * @IWL_AGG_ON: aggregation session is up * @IWL_EMPTYING_HW_QUEUE_ADDBA: establishing a BA session - waiting for the * HW queue to be empty from packets for this RA /TID. * @IWL_EMPTYING_HW_QUEUE_DELBA: tearing down a BA session - waiting for the * HW queue to be empty from packets for this RA /TID. */ enum iwl_mvm_agg_state { IWL_AGG_OFF = 0, IWL_AGG_QUEUED, IWL_AGG_STARTING, IWL_AGG_ON, IWL_EMPTYING_HW_QUEUE_ADDBA, IWL_EMPTYING_HW_QUEUE_DELBA, }; /** * struct iwl_mvm_tid_data - holds the states for each RA / TID * @seq_number: the next WiFi sequence number to use * @next_reclaimed: the WiFi sequence number of the next packet to be acked. * This is basically (last acked packet++). * @rate_n_flags: Rate at which Tx was attempted.

Since the HW * still uses 256 BDs for DMA though, TFD_QUEUE_SIZE_MAX stays 256. * This means that we end up with the following: * HW entries: | 0 | ... | N * 32 | ... | N * 32 + 31 | ... | 255 | * SW entries: | 0 | ... | 31 | * where N is a number between 0 and 7. This means that the SW * data is a window overlayed over the HW queue. */ struct iwl_txq { void *tfds; struct iwl_pcie_first_tb_buf *first_tb_bufs; dma_addr_t first_tb_dma; struct iwl_pcie_txq_entry *entries;

These get * used not only for Rx frames, but for any command response or notification * from the NIC. The driver and NIC manage the Rx buffers by means * of indexes into the circular buffer. * * Rx Queue Indexes * The host/firmware share two index registers for managing the Rx buffers. * * The READ index maps to the first position that the firmware may be writing * to -- the driver can read up to (but not including) this position and get * good data. * The READ index is managed by the firmware once the card is enabled. * * The WRITE index maps to the last position the driver has read from -- the * position preceding WRITE is the last slot the firmware can place a packet. * * The queue is empty (no good data) if WRITE = READ - 1, and is full if * WRITE = READ. * * During initialization, the host sets up the READ queue position to the first * INDEX position, and WRITE to the last (READ - 1 wrapped) * * When the firmware places a packet in a buffer, it will advance the READ index * and fire the RX interrupt. The driver can then query the READ index and * process as many packets as possible, moving the WRITE index forward as it * resets the Rx queue buffers with new memory. * * The management in the driver is as follows: * + A list of pre-allocated RBDs is stored in iwl->rxq->rx_free. * When the interrupt handler is called, the request is processed. * The page is either stolen - transferred to the upper layer * or reused - added immediately to the iwl->rxq->rx_free list. * + When the page is stolen - the driver updates the matching queue's used * count, detaches the RBD and transfers it to the queue used list. * When there are two used RBDs - they are transferred to the allocator empty * list. Work is then scheduled for the allocator to start allocating * eight buffers. * When there are another 6 used RBDs - they are transferred to the allocator * empty list and the driver tries to claim the pre-allocated buffers and * add them to iwl->rxq->rx_free. If it fails - it continues to claim them * until ready. * When there are 8+ buffers in the free list - either from allocation or from * 8 reused unstolen pages - restock is called to update the FW and indexes. * + In order to make sure the allocator always has RBDs to use for allocation * the allocator has initial pool in the size of num_queues*(8-2) - the * maximum missing RBDs per allocation request (request posted with 2 * empty RBDs, there is no guarantee when the other 6 RBDs are supplied). * The queues supplies the recycle of the rest of the RBDs. * + A received packet is processed and handed to the kernel network stack, * detached from the iwl->rxq. The driver 'processed' index is updated. * + If there are no allocated buffers in iwl->rxq->rx_free, * the READ INDEX is not incremented and iwl->status(RX_STALLED) is set. * If there were enough free buffers and RX_STALLED is set it is cleared. * * * Driver sequence: * * iwl_rxq_alloc() Allocates rx_free * iwl_pcie_rx_replenish() Replenishes rx_free list from rx_used, and calls * iwl_pcie_rxq_restock. * Used only during initialization. * iwl_pcie_rxq_restock() Moves available buffers from rx_free into Rx * queue, updates firmware pointers, and updates * the WRITE index. * iwl_pcie_rx_allocator() Background work for allocating pages. * * -- enable interrupts -- * ISR - iwl_rx() Detach iwl_rx_mem_buffers from pool up to the * READ INDEX, detaching the SKB from the pool. * Moves the packet buffer from queue to rx_used. * Posts and claims requests to the allocator. * Calls iwl_pcie_rxq_restock to refill any empty * slots. * * RBD life-cycle: * * Init: * rxq.pool -> rxq.rx_used -> rxq.rx_free -> rxq.queue * * Regular Receive interrupt: * Page Stolen: * rxq.queue -> rxq.rx_used -> allocator.rbd_empty -> * allocator.rbd_allocated -> rxq.rx_free -> rxq.queue * Page not Stolen: * rxq.queue -> rxq.rx_free -> rxq.queue * ... * */ /* * iwl_rxq_space - Return number of free slots available in queue. */ static int iwl_rxq_space(const struct iwl_rxq *rxq) { /* Make sure rx queue size is a power of 2 */ WARN_ON(rxq->queue_size & (rxq->queue_size - 1)); /* * There can be up to (RX_QUEUE_SIZE - 1) free slots, to avoid ambiguity * between empty and completely full queues. * The following is equivalent to modulo by RX_QUEUE_SIZE and is well * defined for negative dividends. */ return (rxq->read - rxq->write - 1) & (rxq->queue_size - 1); } /* * iwl_dma_addr2rbd_ptr - convert a DMA address to a uCode read buffer ptr */ static inline __le32 iwl_pcie_dma_addr2rbd_ptr(dma_addr_t dma_addr) { return cpu_to_le32((u32)(dma_addr >> 8)); } /* * iwl_pcie_rx_stop - stops the Rx DMA */ int iwl_pcie_rx_stop(struct iwl_trans *trans) { if (trans->cfg->device_family >= IWL_DEVICE_FAMILY_22560) { /* TODO: remove this for 22560 once fw does it */ iwl_write_umac_prph(trans, RFH_RXF_DMA_CFG_GEN3, 0); return iwl_poll_umac_prph_bit(trans, RFH_GEN_STATUS_GEN3, RXF_DMA_IDLE, RXF_DMA_IDLE, 1000); } else if (trans->cfg->mq_rx_supported) { iwl_write_prph(trans, RFH_RXF_DMA_CFG, 0); return iwl_poll_prph_bit(trans, RFH_GEN_STATUS, RXF_DMA_IDLE, RXF_DMA_IDLE, 1000); } else { iwl_write_direct32(trans, FH_MEM_RCSR_CHNL0_CONFIG_REG, 0); return iwl_poll_direct_bit(trans, FH_MEM_RSSR_RX_STATUS_REG, FH_RSSR_CHNL0_RX_STATUS_CHNL_IDLE, 1000); } } /* * iwl_pcie_rxq_inc_wr_ptr - Update the write pointer for the RX queue */ static void iwl_pcie_rxq_inc_wr_ptr(struct iwl_trans *trans, struct iwl_rxq *rxq) { u32 reg; lockdep_assert_held(&rxq->lock); /* * explicitly wake up the NIC if: * 1. shadow registers aren't enabled * 2. there is a chance that the NIC is asleep */ if (!trans->cfg->base_params->shadow_reg_enable && test_bit(STATUS_TPOWER_PMI, &trans->status)) { reg = iwl_read32(trans, CSR_UCODE_DRV_GP1); if (reg & CSR_UCODE_DRV_GP1_BIT_MAC_SLEEP) { IWL_DEBUG_INFO(trans, "Rx queue requesting wakeup, GP1 = 0x%x\n", reg); iwl_set_bit(trans, CSR_GP_CNTRL, BIT(trans->cfg->csr->flag_mac_access_req)); rxq->need_update = true; return; } } rxq->write_actual = round_down(rxq->write, 8); if (trans->cfg->device_family == IWL_DEVICE_FAMILY_22560) iwl_write32(trans, HBUS_TARG_WRPTR, (rxq->write_actual | ((FIRST_RX_QUEUE + rxq->id) << 16))); else if (trans->cfg->mq_rx_supported) iwl_write32(trans, RFH_Q_FRBDCB_WIDX_TRG(rxq->id), rxq->write_actual); else iwl_write32(trans, FH_RSCSR_CHNL0_WPTR, rxq->write_actual); } static void iwl_pcie_rxq_check_wrptr(struct iwl_trans *trans) { struct iwl_trans_pcie *trans_pcie = IWL_TRANS_GET_PCIE_TRANS(trans); int i; for (i = 0; i < trans->num_rx_queues; i++) { struct iwl_rxq *rxq = &trans_pcie->rxq[i]; if (!rxq->need_update) continue; spin_lock(&rxq->lock); iwl_pcie_rxq_inc_wr_ptr(trans, rxq); rxq->need_update = false; spin_unlock(&rxq->lock); } } static void iwl_pcie_restock_bd(struct iwl_trans *trans, struct iwl_rxq *rxq, struct iwl_rx_mem_buffer *rxb) { if (trans->cfg->device_family >= IWL_DEVICE_FAMILY_22560) { struct iwl_rx_transfer_desc *bd = rxq->bd; BUILD_BUG_ON(sizeof(*bd) != 2 * sizeof(u64)); bd[rxq->write].addr = cpu_to_le64(rxb->page_dma); bd[rxq->write].rbid = cpu_to_le16(rxb->vid); } else { __le64 *bd = rxq->bd; bd[rxq->write] = cpu_to_le64(rxb->page_dma | rxb->vid); } IWL_DEBUG_RX(trans, "Assigned virtual RB ID %u to queue %d index %d\n", (u32)rxb->vid, rxq->id, rxq->write); } /* * iwl_pcie_rxmq_restock - restock implementation for multi-queue rx */ static void iwl_pcie_rxmq_restock(struct iwl_trans *trans, struct iwl_rxq *rxq) { struct iwl_rx_mem_buffer *rxb; /* * If the device isn't enabled - no need to try to add buffers... * This can happen when we stop the device and still have an interrupt * pending.

/** * enum hwsim_regtest - the type of regulatory tests we offer * * These are the different values you can use for the regtest * module parameter. This is useful to help test world roaming * and the driver regulatory_hint() call and combinations of these. * If you want to do specific alpha2 regulatory domain tests simply * use the userspace regulatory request as that will be respected as * well without the need of this module parameter. This is designed * only for testing the driver regulatory request, world roaming * and all possible combinations. * * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed, * this is the default value. * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory * hint, only one driver regulatory hint will be sent as such the * secondary radios are expected to follow. * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory * request with all radios reporting the same regulatory domain. * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling * different regulatory domains requests. Expected behaviour is for * an intersection to occur but each device will still use their * respective regulatory requested domains. Subsequent radios will * use the resulting intersection. * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish * this by using a custom beacon-capable regulatory domain for the first * radio. All other device world roam. * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory * domain requests. All radios will adhere to this custom world regulatory * domain. * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory * domain requests. The first radio will adhere to the first custom world * regulatory domain, the second one to the second custom world regulatory * domain. All other devices will world roam. * @HWSIM_REGTEST_STRICT_FOLLOW_: Used for testing strict regulatory domain * settings, only the first radio will send a regulatory domain request * and use strict settings. The rest of the radios are expected to follow. * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain * settings. All radios will adhere to this. * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory * domain settings, combined with secondary driver regulatory domain * settings. The first radio will get a strict regulatory domain setting * using the first driver regulatory request and the second radio will use * non-strict settings using the second driver regulatory request. All * other devices should follow the intersection created between the * first two. * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need * at least 6 radios for a complete test. We will test in this order: * 1 - driver custom world regulatory domain * 2 - second custom world regulatory domain * 3 - first driver regulatory domain request * 4 - second driver regulatory domain request * 5 - strict regulatory domain settings using the third driver regulatory * domain request * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio * regulatory requests. */ enum hwsim_regtest { HWSIM_REGTEST_DISABLED = 0, HWSIM_REGTEST_DRIVER_REG_FOLLOW = 1, HWSIM_REGTEST_DRIVER_REG_ALL = 2, HWSIM_REGTEST_DIFF_COUNTRY = 3, HWSIM_REGTEST_WORLD_ROAM = 4, HWSIM_REGTEST_CUSTOM_WORLD = 5, HWSIM_REGTEST_CUSTOM_WORLD_2 = 6, HWSIM_REGTEST_STRICT_FOLLOW = 7, HWSIM_REGTEST_STRICT_ALL = 8, HWSIM_REGTEST_STRICT_AND_DRIVER_REG = 9, HWSIM_REGTEST_ALL = 10, }; /* Set to one of the HWSIM_REGTEST_* values above */ static int regtest = HWSIM_REGTEST_DISABLED; module_param(regtest, int, 0444); MODULE_PARM_DESC(regtest, "The type of regulatory test we want to run"); static const char *hwsim_alpha2s[] = { "FI", "AL", "US", "DE", "JP", "AL", }; static const struct ieee80211_regdomain hwsim_world_regdom_custom_01 = { .n_reg_rules = 4, .alpha2 = "99", .reg_rules = { REG_RULE(2412-10, 2462+10, 40, 0, 20, 0), REG_RULE(2484-10, 2484+10, 40, 0, 20, 0), REG_RULE(5150-10, 5240+10, 40, 0, 30, 0), REG_RULE(5745-10, 5825+10, 40, 0, 30, 0), } }; static const struct ieee80211_regdomain hwsim_world_regdom_custom_02 = { .n_reg_rules = 2, .alpha2 = "99", .reg_rules = { REG_RULE(2412-10, 2462+10, 40, 0, 20, 0), REG_RULE(5725-10, 5850+10, 40, 0, 30, NL80211_RRF_NO_IR), } }; static const struct ieee80211_regdomain *hwsim_world_regdom_custom[] = { &hwsim_world_regdom_custom_01, &hwsim_world_regdom_custom_02, }; struct hwsim_vif_priv { u32 magic; u8 bssid[ETH_ALEN]; bool assoc; bool bcn_en; u16 aid; }; #define HWSIM_VIF_MAGIC 0x69537748 static inline void hwsim_check_magic(struct ieee80211_vif *vif) { struct hwsim_vif_priv *vp = (void *)vif->drv_priv; WARN(vp->magic != HWSIM_VIF_MAGIC, "Invalid VIF (%p) magic %#x, %pM, %d/%d\n", vif, vp->magic, vif->addr, vif->type, vif->p2p); } static inline void hwsim_set_magic(struct ieee80211_vif *vif) { struct hwsim_vif_priv *vp = (void *)vif->drv_priv; vp->magic = HWSIM_VIF_MAGIC; } static inline void hwsim_clear_magic(struct ieee80211_vif *vif) { struct hwsim_vif_priv *vp = (void *)vif->drv_priv; vp->magic = 0; } struct hwsim_sta_priv { u32 magic; }; #define HWSIM_STA_MAGIC 0x6d537749 static inline void hwsim_check_sta_magic(struct ieee80211_sta *sta) { struct hwsim_sta_priv *sp = (void *)sta->drv_priv; WARN_ON(sp->magic != HWSIM_STA_MAGIC); } static inline void hwsim_set_sta_magic(struct ieee80211_sta *sta) { struct hwsim_sta_priv *sp = (void *)sta->drv_priv; sp->magic = HWSIM_STA_MAGIC; } static inline void hwsim_clear_sta_magic(struct ieee80211_sta *sta) { struct hwsim_sta_priv *sp = (void *)sta->drv_priv; sp->magic = 0; } struct hwsim_chanctx_priv { u32 magic; }; #define HWSIM_CHANCTX_MAGIC 0x6d53774a static inline void hwsim_check_chanctx_magic(struct ieee80211_chanctx_conf *c) { struct hwsim_chanctx_priv *cp = (void *)c->drv_priv; WARN_ON(cp->magic != HWSIM_CHANCTX_MAGIC); } static inline void hwsim_set_chanctx_magic(struct ieee80211_chanctx_conf *c) { struct hwsim_chanctx_priv *cp = (void *)c->drv_priv; cp->magic = HWSIM_CHANCTX_MAGIC; } static inline void hwsim_clear_chanctx_magic(struct ieee80211_chanctx_conf *c) { struct hwsim_chanctx_priv *cp = (void *)c->drv_priv; cp->magic = 0; } static unsigned int hwsim_net_id; static DEFINE_IDA(hwsim_netgroup_ida); struct hwsim_net { int netgroup; u32 wmediumd; }; static inline int hwsim_net_get_netgroup(struct net *net) { struct hwsim_net *hwsim_net = net_generic(net, hwsim_net_id); return hwsim_net->netgroup; } static inline int hwsim_net_set_netgroup(struct net *net) { struct hwsim_net *hwsim_net = net_generic(net, hwsim_net_id); hwsim_net->netgroup = ida_simple_get(&hwsim_netgroup_ida, 0, 0, GFP_KERNEL); return hwsim_net->netgroup >= 0 ?

configuration API for 802.11 devices in Linux. It bridges * userspace and drivers, and offers some utility functionality associated * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used * by all modern wireless drivers in Linux, so that they offer a consistent * API through nl80211. For backward compatibility, cfg80211 also offers * wireless extensions to userspace, but hides them from drivers completely. * * Additionally, cfg80211 contains code to help enforce regulatory spectrum * use restrictions. */ /** * DOC: Device registration * * In order for a driver to use cfg80211, it must register the hardware device * with cfg80211. This happens through a number of hardware capability structs * described below. * * The fundamental structure for each device is the 'wiphy', of which each * instance describes a physical wireless device connected to the system.

The * wdev may be %NULL if power was set for the wiphy, and will * always be %NULL unless the driver supports per-vif TX power * (as advertised by the nl80211 feature flag.) * @get_tx_power: store the current TX power into the dbm variable; * return 0 if successful * * @set_wds_peer: set the WDS peer for a WDS interface * * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting * functions to adjust rfkill hw state * * @dump_survey: get site survey information. * * @remain_on_channel: Request the driver to remain awake on the specified * channel for the specified duration to complete an off-channel * operation (e.g., public action frame exchange). When the driver is * ready on the requested channel, it must indicate this with an event * notification by calling cfg80211_ready_on_channel(). * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation. * This allows the operation to be terminated prior to timeout based on * the duration value. * @mgmt_tx: Transmit a management frame. * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management * frame on another channel * * @testmode_cmd: run a test mode command; @wdev may be %NULL * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be * used by the function, but 0 and 1 must not be touched. Additionally, * return error codes other than -ENOBUFS and -ENOENT will terminate the * dump and return to userspace with an error, so be careful. If any data * was passed in from userspace then the data/len arguments will be present * and point to the data contained in %NL80211_ATTR_TESTDATA. * * @set_bitrate_mask: set the bitrate mask configuration * * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac * devices running firmwares capable of generating the (re) association * RSN IE. It allows for faster roaming between WPA2 BSSIDs. * @del_pmksa: Delete a cached PMKID. * @flush_pmksa: Flush all cached PMKIDs. * @set_power_mgmt: Configure WLAN power management. A timeout value of -1 * allows the driver to adjust the dynamic ps timeout value. * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold. * After configuration, the driver should (soon) send an event indicating * the current level is above/below the configured threshold; this may * need some care when the configuration is changed (without first being * disabled.) * @set_cqm_rssi_range_config: Configure two RSSI thresholds in the * connection quality monitor. An event is to be sent only when the * signal level is found to be outside the two values. The driver should * set %NL80211_EXT_FEATURE_CQM_RSSI_LIST if this method is implemented. * If it is provided then there's no point providing @set_cqm_rssi_config. * @set_cqm_txe_config: Configure connection quality monitor TX error * thresholds. * @sched_scan_start: Tell the driver to start a scheduled scan. * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan with * given request id. This call must stop the scheduled scan and be ready * for starting a new one before it returns, i.e. @sched_scan_start may be * called immediately after that again and should not fail in that case. * The driver should not call cfg80211_sched_scan_stopped() for a requested * stop (when this method returns 0). * * @mgmt_frame_register: Notify driver that a management frame type was * registered. The callback is allowed to sleep. * * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device. * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may * reject TX/RX mask combinations they cannot support by returning -EINVAL * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX). * * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant). * * @tdls_mgmt: Transmit a TDLS management frame. * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup). * * @probe_client: probe an associated client, must return a cookie that it * later passes to cfg80211_probe_status(). * * @set_noack_map: Set the NoAck Map for the TIDs. * * @get_channel: Get the current operating channel for the virtual interface. * For monitor interfaces, it should return %NULL unless there's a single * current monitoring channel. * * @start_p2p_device: Start the given P2P device. * @stop_p2p_device: Stop the given P2P device. * * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode. * Parameters include ACL policy, an array of MAC address of stations * and the number of MAC addresses. If there is already a list in driver * this new list replaces the existing one. Driver has to clear its ACL * when number of MAC addresses entries is passed as 0. Drivers which * advertise the support for MAC based ACL have to implement this callback. * * @start_radar_detection: Start radar detection in the driver. * * @update_ft_ies: Provide updated Fast BSS Transition information to the * driver. If the SME is in the driver/firmware, this information can be * used in building Authentication and Reassociation Request frames. * * @crit_proto_start: Indicates a critical protocol needs more link reliability * for a given duration (milliseconds). The protocol is provided so the * driver can take the most appropriate actions. * @crit_proto_stop: Indicates critical protocol no longer needs increased link * reliability. This operation can not fail. * @set_coalesce: Set coalesce parameters. * * @channel_switch: initiate channel-switch procedure (with CSA). Driver is * responsible for veryfing if the switch is possible. Since this is * inherently tricky driver may decide to disconnect an interface later * with cfg80211_stop_iface(). This doesn't mean driver can accept * everything. It should do it's best to verify requests and reject them * as soon as possible. * * @set_qos_map: Set QoS mapping information to the driver * * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the * given interface This is used e.g. for dynamic HT 20/40 MHz channel width * changes during the lifetime of the BSS. * * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device * with the given parameters; action frame exchange has been handled by * userspace so this just has to modify the TX path to take the TS into * account. * If the admitted time is 0 just validate the parameters to make sure * the session can be created at all; it is valid to just always return * success for that but that may result in inefficient behaviour (handshake * with the peer followed by immediate teardown when the addition is later * rejected) * @del_tx_ts: remove an existing TX TS * * @join_ocb: join the OCB network with the specified parameters * (invoked with the wireless_dev mutex held) * @leave_ocb: leave the current OCB network * (invoked with the wireless_dev mutex held) * * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver * is responsible for continually initiating channel-switching operations * and returning to the base channel for communication with the AP. * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both * peers must be on the base channel when the call completes. * @start_nan: Start the NAN interface. * @stop_nan: Stop the NAN interface. * @add_nan_func: Add a NAN function. Returns negative value on failure. * On success @nan_func ownership is transferred to the driver and * it may access it outside of the scope of this function. The driver * should free the @nan_func when no longer needed by calling * cfg80211_free_nan_func(). * On success the driver should assign an instance_id in the * provided @nan_func. * @del_nan_func: Delete a NAN function. * @nan_change_conf: changes NAN configuration. The changed parameters must * be specified in @changes (using &enum cfg80211_nan_conf_changes); * All other parameters must be ignored. * * @set_multicast_to_unicast: configure multicast to unicast conversion for BSS * * @get_txq_stats: Get TXQ stats for interface or phy. If wdev is %NULL, this * function should return phy stats, and interface stats otherwise. * * @set_pmk: configure the PMK to be used for offloaded 802.1X 4-Way handshake. * If not deleted through @del_pmk the PMK remains valid until disconnect * upon which the driver should clear it. * (invoked with the wireless_dev mutex held) * @del_pmk: delete the previously configured PMK for the given authenticator. * (invoked with the wireless_dev mutex held) * * @external_auth: indicates result of offloaded authentication processing from * user space * * @tx_control_port: TX a control port frame (EAPoL). The noencrypt parameter * tells the driver that the frame should not be encrypted. * * @get_ftm_responder_stats: Retrieve FTM responder statistics, if available. * Statistics should be cumulative, currently no way to reset is provided. * @start_pmsr: start peer measurement (e.g. FTM) * @abort_pmsr: abort peer measurement */ struct cfg80211_ops { int (*suspend)(struct wiphy *wiphy, struct cfg80211_wowlan *wow);

Drivers must ensure all work added onto the * mac80211 workqueue should be cancelled on the driver stop() callback. * * mac80211 will flushed the workqueue upon interface removal and during * suspend. * * All work performed on the mac80211 workqueue must not acquire the RTNL lock. * */ /** * DOC: mac80211 software tx queueing * * mac80211 provides an optional intermediate queueing implementation designed * to allow the driver to keep hardware queues short and provide some fairness * between different stations/interfaces. * In this model, the driver pulls data frames from the mac80211 queue instead * of letting mac80211 push them via drv_tx(). * Other frames (e.g. control or management) are still pushed using drv_tx(). * * Drivers indicate that they use this model by implementing the .wake_tx_queue * driver operation. * * Intermediate queues (struct ieee80211_txq) are kept per-sta per-tid, with * another per-sta for non-data/non-mgmt and bufferable management frames, and * a single per-vif queue for multicast data frames. * * The driver is expected to initialize its private per-queue data for stations * and interfaces in the .add_interface and .sta_add ops. * * The driver can't access the queue directly. To dequeue a frame, it calls * ieee80211_tx_dequeue(). Whenever mac80211 adds a new frame to a queue, it * calls the .wake_tx_queue driver op. * * For AP powersave TIM handling, the driver only needs to indicate if it has * buffered packets in the driver specific data structures by calling * ieee80211_sta_set_buffered(). For frames buffered in the ieee80211_txq * struct, mac80211 sets the appropriate TIM PVB bits and calls * .release_buffered_frames(). * In that callback the driver is therefore expected to release its own * buffered frames and afterwards also frames from the ieee80211_txq (obtained * via the usual ieee80211_tx_dequeue). */ struct device; /** * enum ieee80211_max_queues - maximum number of queues * * @IEEE80211_MAX_QUEUES: Maximum number of regular device queues. * @IEEE80211_MAX_QUEUE_MAP: bitmap with maximum queues set */ enum ieee80211_max_queues { IEEE80211_MAX_QUEUES = 16, IEEE80211_MAX_QUEUE_MAP = BIT(IEEE80211_MAX_QUEUES) - 1, }; #define IEEE80211_INVAL_HW_QUEUE 0xff /** * enum ieee80211_ac_numbers - AC numbers as used in mac80211 * @IEEE80211_AC_VO: voice * @IEEE80211_AC_VI: video * @IEEE80211_AC_BE: best effort * @IEEE80211_AC_BK: background */ enum ieee80211_ac_numbers { IEEE80211_AC_VO = 0, IEEE80211_AC_VI = 1, IEEE80211_AC_BE = 2, IEEE80211_AC_BK = 3, }; /** * struct ieee80211_tx_queue_params - transmit queue configuration * * The information provided in this structure is required for QoS * transmit queue configuration.

The callback takes a @sta parameter that will be NULL * for default keys or keys used for transmission only, or point to * the station information for the peer for individual keys. * Multiple transmission keys with the same key index may be used when * VLANs are configured for an access point. * * When transmitting, the TX control data will use the @hw_key_idx * selected by the driver by modifying the &struct ieee80211_key_conf * pointed to by the @key parameter to the set_key() function. * * The set_key() call for the %SET_KEY command should return 0 if * the key is now in use, -%EOPNOTSUPP or -%ENOSPC if it couldn't be * added; if you return 0 then hw_key_idx must be assigned to the * hardware key index, you are free to use the full u8 range. * * Note that in the case that the @IEEE80211_HW_SW_CRYPTO_CONTROL flag is * set, mac80211 will not automatically fall back to software crypto if * enabling hardware crypto failed.

Those drivers should provide update_tkip_key * handler. * The update_tkip_key() call updates the driver with the new phase 1 key. * This happens every time the iv16 wraps around (every 65536 packets). The * set_key() call will happen only once for each key (unless the AP did * rekeying), it will not include a valid phase 1 key. The valid phase 1 key is * provided by update_tkip_key only. The trigger that makes mac80211 call this * handler is software decryption with wrap around of iv16. * * The set_default_unicast_key() call updates the default WEP key index * configured to the hardware for WEP encryption type. This is required * for devices that support offload of data packets (e.g. ARP responses). * * Mac80211 drivers should set the @NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 flag * when they are able to replace in-use PTK keys according to to following * requirements: * 1) They do not hand over frames decrypted with the old key to mac80211 once the call to set_key() with command %DISABLE_KEY has been completed when also setting @IEEE80211_KEY_FLAG_GENERATE_IV for any key, 2) either drop or continue to use the old key for any outgoing frames queued at the time of the key deletion (including re-transmits), 3) never send out a frame queued prior to the set_key() %SET_KEY command encrypted with the new key and 4) never send out a frame unencrypted when it should be encrypted.

In that case, it will be told about the desired powersave mode * with the %IEEE80211_CONF_PS flag depending on the association status. * The hardware must take care of sending nullfunc frames when necessary, * i.e. when entering and leaving powersave mode. The hardware is required * to look at the AID in beacons and signal to the AP that it woke up when * it finds traffic directed to it. * * %IEEE80211_CONF_PS flag enabled means that the powersave mode defined in * IEEE 802.11-2007 section 11.2 is enabled. This is not to be confused * with hardware wakeup and sleep states. Driver is responsible for waking * up the hardware before issuing commands to the hardware and putting it * back to sleep at appropriate times. * * When PS is enabled, hardware needs to wakeup for beacons and receive the * buffered multicast/broadcast frames after the beacon. Also it must be * possible to send frames and receive the acknowledment frame. * * Other hardware designs cannot send nullfunc frames by themselves and also * need software support for parsing the TIM bitmap. This is also supported * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still * required to pass up beacons. The hardware is still required to handle * waking up for multicast traffic; if it cannot the driver must handle that * as best as it can, mac80211 is too slow to do that. * * Dynamic powersave is an extension to normal powersave in which the * hardware stays awake for a user-specified period of time after sending a * frame so that reply frames need not be buffered and therefore delayed to * the next wakeup. It's compromise of getting good enough latency when * there's data traffic and still saving significantly power in idle * periods. * * Dynamic powersave is simply supported by mac80211 enabling and disabling * PS based on traffic.

It usually works so that * the firmware creates a checksum of the beacon but omits all constantly * changing elements (TSF, TIM etc). Whenever the checksum changes the * beacon is forwarded to the host, otherwise it will be just dropped. That * way the host will only receive beacons where some relevant information * (for example ERP protection or WMM settings) have changed. * * Beacon filter support is advertised with the %IEEE80211_VIF_BEACON_FILTER * interface capability. The driver needs to enable beacon filter support * whenever power save is enabled, that is %IEEE80211_CONF_PS is set. When * power save is enabled, the stack will not check for beacon loss and the * driver needs to notify about loss of beacons with ieee80211_beacon_loss(). * * The time (or number of beacons missed) until the firmware notifies the * driver of a beacon loss event (which in turn causes the driver to call * ieee80211_beacon_loss()) should be configurable and will be controlled * by mac80211 and the roaming algorithm in the future. * * Since there may be constantly changing information elements that nothing * in the software stack cares about, we will, in the future, have mac80211 * tell the driver which information elements are interesting in the sense * that we want to see changes in them. This will include * * - a list of information element IDs * - a list of OUIs for the vendor information element * * Ideally, the hardware would filter out any beacons without changes in the * requested elements, but if it cannot support that it may, at the expense * of some efficiency, filter out only a subset. For example, if the device * doesn't support checking for OUIs it should pass up all changes in all * vendor information elements. * * Note that change, for the sake of simplification, also includes information * elements appearing or disappearing from the beacon. * * Some hardware supports an "ignore list" instead, just make sure nothing * that was requested is on the ignore list, and include commonly changing * information element IDs in the ignore list, for example 11 (BSS load) and * the various vendor-assigned IEs with unknown contents (128, 129, 133-136, * 149, 150, 155, 156, 173, 176, 178, 179, 219); for forward compatibility * it could also include some currently unused IDs. * * * In addition to these capabilities, hardware should support notifying the * host of changes in the beacon RSSI. This is relevant to implement roaming * when no traffic is flowing (when traffic is flowing we see the RSSI of * the received data packets). This can consist in notifying the host when * the RSSI changes significantly or when it drops below or rises above * configurable thresholds. In the future these thresholds will also be * configured by mac80211 (which gets them from userspace) to implement * them as the roaming algorithm requires. * * If the hardware cannot implement this, the driver should ask it to * periodically pass beacon frames to the host so that software can do the * signal strength threshold checking. */ /** * DOC: Spatial multiplexing power save * * SMPS (Spatial multiplexing power save) is a mechanism to conserve * power in an 802.11n implementation. For details on the mechanism * and rationale, please refer to 802.11 (as amended by 802.11n-2009) * "11.2.3 SM power save". * * The mac80211 implementation is capable of sending action frames * to update the AP about the station's SMPS mode, and will instruct * the driver to enter the specific mode.

However, for best CPU usage and power consumption, * having as few frames as possible percolate through the stack is * desirable. Hence, the hardware should filter as much as possible. * * To achieve this, mac80211 uses filter flags (see below) to tell * the driver's configure_filter() function which frames should be * passed to mac80211 and which should be filtered out. * * Before configure_filter() is invoked, the prepare_multicast() * callback is invoked with the parameters @mc_count and @mc_list * for the combined multicast address list of all virtual interfaces. * It's use is optional, and it returns a u64 that is passed to * configure_filter(). Additionally, configure_filter() has the * arguments @changed_flags telling which flags were changed and * @total_flags with the new flag states. * * If your device has no multicast address filters your driver will * need to check both the %FIF_ALLMULTI flag and the @mc_count * parameter to see whether multicast frames should be accepted * or dropped. * * All unsupported flags in @total_flags must be cleared. * Hardware does not support a flag if it is incapable of _passing_ * the frame to the stack. Otherwise the driver must ignore * the flag, but not clear it. * You must _only_ clear the flag (announce no support for the * flag to mac80211) if you are not able to pass the packet type * to the stack (so the hardware always filters it). * So for example, you should clear @FIF_CONTROL, if your hardware * always filters control frames. If your hardware always passes * control frames to the kernel and is incapable of filtering them, * you do _not_ clear the @FIF_CONTROL flag. * This rule applies to all other FIF flags as well. */ /** * DOC: AP support for powersaving clients * * In order to implement AP and P2P GO modes, mac80211 has support for * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD. * There currently is no support for sAPSD. * * There is one assumption that mac80211 makes, namely that a client * will not poll with PS-Poll and trigger with uAPSD at the same time. * Both are supported, and both can be used by the same client, but * they can't be used concurrently by the same client. This simplifies * the driver code. * * The first thing to keep in mind is that there is a flag for complete * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set, * mac80211 expects the driver to handle most of the state machine for * powersaving clients and will ignore the PM bit in incoming frames. * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of * stations' powersave transitions. In this mode, mac80211 also doesn't * handle PS-Poll/uAPSD. * * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the * PM bit in incoming frames for client powersave transitions. When a * station goes to sleep, we will stop transmitting to it. There is, * however, a race condition: a station might go to sleep while there is * data buffered on hardware queues. If the device has support for this * it will reject frames, and the driver should give the frames back to * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will * cause mac80211 to retry the frame when the station wakes up. The * driver is also notified of powersave transitions by calling its * @sta_notify callback. * * When the station is asleep, it has three choices: it can wake up, * it can PS-Poll, or it can possibly start a uAPSD service period. * Waking up is implemented by simply transmitting all buffered (and * filtered) frames to the station. This is the easiest case. When * the station sends a PS-Poll or a uAPSD trigger frame, mac80211 * will inform the driver of this with the @allow_buffered_frames * callback; this callback is optional. mac80211 will then transmit * the frames as usual and set the %IEEE80211_TX_CTL_NO_PS_BUFFER * on each frame. The last frame in the service period (or the only * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to * indicate that it ends the service period; as this frame must have * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS. * When TX status is reported for this frame, the service period is * marked has having ended and a new one can be started by the peer. * * Additionally, non-bufferable MMPDUs can also be transmitted by * mac80211 with the %IEEE80211_TX_CTL_NO_PS_BUFFER set in them. * * Another race condition can happen on some devices like iwlwifi * when there are frames queued for the station and it wakes up * or polls; the frames that are already queued could end up being * transmitted first instead, causing reordering and/or wrong * processing of the EOSP. The cause is that allowing frames to be * transmitted to a certain station is out-of-band communication to * the device. To allow this problem to be solved, the driver can * call ieee80211_sta_block_awake() if frames are buffered when it * is notified that the station went to sleep. When all these frames * have been filtered (see above), it must call the function again * to indicate that the station is no longer blocked. * * If the driver buffers frames in the driver for aggregation in any * way, it must use the ieee80211_sta_set_buffered() call when it is * notified of the station going to sleep to inform mac80211 of any * TIDs that have frames buffered. Note that when a station wakes up * this information is reset (hence the requirement to call it when * informed of the station going to sleep). Then, when a service * period starts for any reason, @release_buffered_frames is called * with the number of frames to be released and which TIDs they are * to come from. In this case, the driver is responsible for setting * the EOSP (for uAPSD) and MORE_DATA bits in the released frames, * to help the @more_data parameter is passed to tell the driver if * there is more data on other TIDs -- the TIDs to release frames * from are ignored since mac80211 doesn't know how many frames the * buffers for those TIDs contain. * * If the driver also implement GO mode, where absence periods may * shorten service periods (or abort PS-Poll responses), it must * filter those response frames except in the case of frames that * are buffered in the driver -- those must remain buffered to avoid * reordering. Because it is possible that no frames are released * in this case, the driver must call ieee80211_sta_eosp() * to indicate to mac80211 that the service period ended anyway. * * Finally, if frames from multiple TIDs are released from mac80211 * but the driver might reorder them, it must clear & set the flags * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP) * and also take care of the EOSP and MORE_DATA bits in the frame. * The driver may also use ieee80211_sta_eosp() in this case. * * Note that if the driver ever buffers frames other than QoS-data * frames, it must take care to never send a non-QoS-data frame as * the last frame in a service period, adding a QoS-nulldata frame * after a non-QoS-data frame if needed. */ /** * DOC: HW queue control * * Before HW queue control was introduced, mac80211 only had a single static * assignment of per-interface AC software queues to hardware queues. This * was problematic for a few reasons: * 1) off-channel transmissions might get stuck behind other frames * 2) multiple virtual interfaces couldn't be handled correctly * 3) after-DTIM frames could get stuck behind other frames * * To solve this, hardware typically uses multiple different queues for all * the different usages, and this needs to be propagated into mac80211 so it * won't have the same problem with the software queues. * * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability * flag that tells it that the driver implements its own queue control. To do * so, the driver will set up the various queues in each &struct ieee80211_vif * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and * if necessary will queue the frame on the right software queue that mirrors * the hardware queue. * Additionally, the driver has to then use these HW queue IDs for the queue * management functions (ieee80211_stop_queue() et al.) * * The driver is free to set up the queue mappings as needed, multiple virtual * interfaces may map to the same hardware queues if needed. The setup has to * happen during add_interface or change_interface callbacks. For example, a * driver supporting station+station and station+AP modes might decide to have * 10 hardware queues to handle different scenarios: * * 4 AC HW queues for 1st vif: 0, 1, 2, 3 * 4 AC HW queues for 2nd vif: 4, 5, 6, 7 * after-DTIM queue for AP: 8 * off-channel queue: 9 * * It would then set up the hardware like this: * hw.offchannel_tx_hw_queue = 9 * * and the first virtual interface that is added as follows: * vif.hw_queue[IEEE80211_AC_VO] = 0 * vif.hw_queue[IEEE80211_AC_VI] = 1 * vif.hw_queue[IEEE80211_AC_BE] = 2 * vif.hw_queue[IEEE80211_AC_BK] = 3 * vif.cab_queue = 8 // if AP mode, otherwise %IEEE80211_INVAL_HW_QUEUE * and the second virtual interface with 4-7. * * If queue 6 gets full, for example, mac80211 would only stop the second * virtual interface's BE queue since virtual interface queues are per AC. * * Note that the vif.cab_queue value should be set to %IEEE80211_INVAL_HW_QUEUE * whenever the queue is not used (i.e. the interface is not in AP mode) if the * queue could potentially be shared since mac80211 will look at cab_queue when * a queue is stopped/woken even if the interface is not in AP mode. */ /** * enum ieee80211_filter_flags - hardware filter flags * * These flags determine what the filter in hardware should be * programmed to let through and what should not be passed to the * stack.

Can be NULL, if the driver doesn't need * this notification. * The callback can sleep. * * @get_stats: Return low-level statistics. * Returns zero if statistics are available. * The callback can sleep. * * @get_key_seq: If your device implements encryption in hardware and does * IV/PN assignment then this callback should be provided to read the * IV/PN for the given key from hardware. * The callback must be atomic. * * @set_frag_threshold: Configuration of fragmentation threshold. Assign this * if the device does fragmentation by itself. Note that to prevent the * stack from doing fragmentation IEEE80211_HW_SUPPORTS_TX_FRAG * should be set as well. * The callback can sleep. * * @set_rts_threshold: Configuration of RTS threshold (if device needs it) * The callback can sleep. * * @sta_add: Notifies low level driver about addition of an associated station, * AP, IBSS/WDS/mesh peer etc. This callback can sleep. * * @sta_remove: Notifies low level driver about removal of an associated * station, AP, IBSS/WDS/mesh peer etc. Note that after the callback * returns it isn't safe to use the pointer, not even RCU protected; * no RCU grace period is guaranteed between returning here and freeing * the station. See @sta_pre_rcu_remove if needed. * This callback can sleep. * * @sta_add_debugfs: Drivers can use this callback to add debugfs files * when a station is added to mac80211's station list. This callback * should be within a CPTCFG_MAC80211_DEBUGFS conditional. This * callback can sleep. * * @sta_notify: Notifies low level driver about power state transition of an * associated station, AP, IBSS/WDS/mesh peer etc. For a VIF operating * in AP mode, this callback will not be called when the flag * %IEEE80211_HW_AP_LINK_PS is set. Must be atomic. * * @sta_state: Notifies low level driver about state transition of a * station (which can be the AP, a client, IBSS/WDS/mesh peer etc.) * This callback is mutually exclusive with @sta_add/@sta_remove. * It must not fail for down transitions but may fail for transitions * up the list of states. Also note that after the callback returns it * isn't safe to use the pointer, not even RCU protected - no RCU grace * period is guaranteed between returning here and freeing the station. * See @sta_pre_rcu_remove if needed. * The callback can sleep. * * @sta_pre_rcu_remove: Notify driver about station removal before RCU * synchronisation. This is useful if a driver needs to have station * pointers protected using RCU, it can then use this call to clear * the pointers instead of waiting for an RCU grace period to elapse * in @sta_state. * The callback can sleep. * * @sta_rc_update: Notifies the driver of changes to the bitrates that can be * used to transmit to the station. The changes are advertised with bits * from &enum ieee80211_rate_control_changed and the values are reflected * in the station data. This callback should only be used when the driver * uses hardware rate control (%IEEE80211_HW_HAS_RATE_CONTROL) since * otherwise the rate control algorithm is notified directly. * Must be atomic. * @sta_rate_tbl_update: Notifies the driver that the rate table changed. This * is only used if the configured rate control algorithm actually uses * the new rate table API, and is therefore optional. Must be atomic. * * @sta_statistics: Get statistics for this station. For example with beacon * filtering, the statistics kept by mac80211 might not be accurate, so * let the driver pre-fill the statistics. The driver can fill most of * the values (indicating which by setting the filled bitmap), but not * all of them make sense - see the source for which ones are possible. * Statistics that the driver doesn't fill will be filled by mac80211. * The callback can sleep. * * @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max), * bursting) for a hardware TX queue. * Returns a negative error code on failure. * The callback can sleep. * * @get_tsf: Get the current TSF timer value from firmware/hardware. Currently, * this is only used for IBSS mode BSSID merging and debugging. Is not a * required function. * The callback can sleep. * * @set_tsf: Set the TSF timer to the specified value in the firmware/hardware. * Currently, this is only used for IBSS mode debugging. Is not a * required function. * The callback can sleep. * * @offset_tsf: Offset the TSF timer by the specified value in the * firmware/hardware. Preferred to set_tsf as it avoids delay between * calling set_tsf() and hardware getting programmed, which will show up * as TSF delay. Is not a required function. * The callback can sleep. * * @reset_tsf: Reset the TSF timer and allow firmware/hardware to synchronize * with other STAs in the IBSS. This is only used in IBSS mode. This * function is optional if the firmware/hardware takes full care of * TSF synchronization. * The callback can sleep. * * @tx_last_beacon: Determine whether the last IBSS beacon was sent by us. * This is needed only for IBSS mode and the result of this function is * used to determine whether to reply to Probe Requests. * Returns non-zero if this device sent the last beacon. * The callback can sleep. * * @get_survey: Return per-channel survey information * * @rfkill_poll: Poll rfkill hardware state. If you need this, you also * need to set wiphy->rfkill_poll to %true before registration, * and need to call wiphy_rfkill_set_hw_state() in the callback. * The callback can sleep. * * @set_coverage_class: Set slot time for given coverage class as specified * in IEEE 802.11-2007 section 17.3.8.6 and modify ACK timeout * accordingly; coverage class equals to -1 to enable ACK timeout * estimation algorithm (dynack). To disable dynack set valid value for * coverage class. This callback is not required and may sleep. * * @testmode_cmd: Implement a cfg80211 test mode command. The passed @vif may * be %NULL. The callback can sleep. * @testmode_dump: Implement a cfg80211 test mode dump. The callback can sleep. * * @flush: Flush all pending frames from the hardware queue, making sure * that the hardware queues are empty. The @queues parameter is a bitmap * of queues to flush, which is useful if different virtual interfaces * use different hardware queues; it may also indicate all queues. * If the parameter @drop is set to %true, pending frames may be dropped. * Note that vif can be NULL. * The callback can sleep. * * @channel_switch: Drivers that need (or want) to offload the channel * switch operation for CSAs received from the AP may implement this * callback. They must then call ieee80211_chswitch_done() to indicate * completion of the channel switch. * * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device. * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may * reject TX/RX mask combinations they cannot support by returning -EINVAL * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX). * * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant). * * @remain_on_channel: Starts an off-channel period on the given channel, must * call back to ieee80211_ready_on_channel() when on that channel. Note * that normal channel traffic is not stopped as this is intended for hw * offload. Frames to transmit on the off-channel channel are transmitted * normally except for the %IEEE80211_TX_CTL_TX_OFFCHAN flag. When the * duration (which will always be non-zero) expires, the driver must call * ieee80211_remain_on_channel_expired(). * Note that this callback may be called while the device is in IDLE and * must be accepted in this case. * This callback may sleep. * @cancel_remain_on_channel: Requests that an ongoing off-channel period is * aborted before it expires. This callback may sleep. * * @set_ringparam: Set tx and rx ring sizes. * * @get_ringparam: Get tx and rx ring current and maximum sizes. * * @tx_frames_pending: Check if there is any pending frame in the hardware * queues before entering power save. * * @set_bitrate_mask: Set a mask of rates to be used for rate control selection * when transmitting a frame. Currently only legacy rates are handled. * The callback can sleep. * @event_callback: Notify driver about any event in mac80211. See * &enum ieee80211_event_type for the different types. * The callback must be atomic. * * @release_buffered_frames: Release buffered frames according to the given * parameters. In the case where the driver buffers some frames for * sleeping stations mac80211 will use this callback to tell the driver * to release some frames, either for PS-poll or uAPSD. * Note that if the @more_data parameter is %false the driver must check * if there are more frames on the given TIDs, and if there are more than * the frames being released then it must still set the more-data bit in * the frame. If the @more_data parameter is %true, then of course the * more-data bit must always be set. * The @tids parameter tells the driver which TIDs to release frames * from, for PS-poll it will always have only a single bit set. * In the case this is used for a PS-poll initiated release, the * @num_frames parameter will always be 1 so code can be shared. In * this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag * on the TX status (and must report TX status) so that the PS-poll * period is properly ended. This is used to avoid sending multiple * responses for a retried PS-poll frame. * In the case this is used for uAPSD, the @num_frames parameter may be * bigger than one, but the driver may send fewer frames (it must send * at least one, however). In this case it is also responsible for * setting the EOSP flag in the QoS header of the frames. Also, when the * service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP * on the last frame in the SP. Alternatively, it may call the function * ieee80211_sta_eosp() to inform mac80211 of the end of the SP. * This callback must be atomic. * @allow_buffered_frames: Prepare device to allow the given number of frames * to go out to the given station. The frames will be sent by mac80211 * via the usual TX path after this call. The TX information for frames * released will also have the %IEEE80211_TX_CTL_NO_PS_BUFFER flag set * and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case * frames from multiple TIDs are released and the driver might reorder * them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag * on the last frame and clear it on all others and also handle the EOSP * bit in the QoS header correctly. Alternatively, it can also call the * ieee80211_sta_eosp() function. * The @tids parameter is a bitmap and tells the driver which TIDs the * frames will be on; it will at most have two bits set. * This callback must be atomic. * * @get_et_sset_count: Ethtool API to get string-set count. * * @get_et_stats: Ethtool API to get a set of u64 stats. * * @get_et_strings: Ethtool API to get a set of strings to describe stats * and perhaps other supported types of ethtool data-sets. * * @mgd_prepare_tx: Prepare for transmitting a management frame for association * before associated. In multi-channel scenarios, a virtual interface is * bound to a channel before it is associated, but as it isn't associated * yet it need not necessarily be given airtime, in particular since any * transmission to a P2P GO needs to be synchronized against the GO's * powersave state. mac80211 will call this function before transmitting a * management frame prior to having successfully associated to allow the * driver to give it channel time for the transmission, to get a response * and to be able to synchronize with the GO. * For drivers that set %IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP, mac80211 * would also call this function before transmitting a deauthentication * frame in case that no beacon was heard from the AP/P2P GO. * The callback will be called before each transmission and upon return * mac80211 will transmit the frame right away. * If duration is greater than zero, mac80211 hints to the driver the * duration for which the operation is requested. * The callback is optional and can (should!) sleep. * * @mgd_protect_tdls_discover: Protect a TDLS discovery session. After sending * a TDLS discovery-request, we expect a reply to arrive on the AP's * channel. We must stay on the channel (no PSM, scan, etc.), since a TDLS * setup-response is a direct packet not buffered by the AP. * mac80211 will call this function just before the transmission of a TDLS * discovery-request. The recommended period of protection is at least * 2 * (DTIM period). * The callback is optional and can sleep. * * @add_chanctx: Notifies device driver about new channel context creation. * This callback may sleep. * @remove_chanctx: Notifies device driver about channel context destruction. * This callback may sleep. * @change_chanctx: Notifies device driver about channel context changes that * may happen when combining different virtual interfaces on the same * channel context with different settings * This callback may sleep. * @assign_vif_chanctx: Notifies device driver about channel context being bound * to vif. Possible use is for hw queue remapping. * This callback may sleep. * @unassign_vif_chanctx: Notifies device driver about channel context being * unbound from vif. * This callback may sleep. * @switch_vif_chanctx: switch a number of vifs from one chanctx to * another, as specified in the list of * @ieee80211_vif_chanctx_switch passed to the driver, according * to the mode defined in &ieee80211_chanctx_switch_mode. * This callback may sleep. * * @start_ap: Start operation on the AP interface, this is called after all the * information in bss_conf is set and beacon can be retrieved. A channel * context is bound before this is called. Note that if the driver uses * software scan or ROC, this (and @stop_ap) isn't called when the AP is * just "paused" for scanning/ROC, which is indicated by the beacon being * disabled/enabled via @bss_info_changed. * @stop_ap: Stop operation on the AP interface. * * @reconfig_complete: Called after a call to ieee80211_restart_hw() and * during resume, when the reconfiguration has completed. * This can help the driver implement the reconfiguration step (and * indicate mac80211 is ready to receive frames). * This callback may sleep. * * @ipv6_addr_change: IPv6 address assignment on the given interface changed. * Currently, this is only called for managed or P2P client interfaces. * This callback is optional; it must not sleep. * * @channel_switch_beacon: Starts a channel switch to a new channel. * Beacons are modified to include CSA or ECSA IEs before calling this * function. The corresponding count fields in these IEs must be * decremented, and when they reach 1 the driver must call * ieee80211_csa_finish(). Drivers which use ieee80211_beacon_get() * get the csa counter decremented by mac80211, but must check if it is * 1 using ieee80211_csa_is_complete() after the beacon has been * transmitted and then call ieee80211_csa_finish(). * If the CSA count starts as zero or 1, this function will not be called, * since there won't be any time to beacon before the switch anyway. * @pre_channel_switch: This is an optional callback that is called * before a channel switch procedure is started (ie. when a STA * gets a CSA or a userspace initiated channel-switch), allowing * the driver to prepare for the channel switch. * @post_channel_switch: This is an optional callback that is called * after a channel switch procedure is completed, allowing the * driver to go back to a normal configuration. * @abort_channel_switch: This is an optional callback that is called * when channel switch procedure was completed, allowing the * driver to go back to a normal configuration. * @channel_switch_rx_beacon: This is an optional callback that is called * when channel switch procedure is in progress and additional beacon with * CSA IE was received, allowing driver to track changes in count. * @join_ibss: Join an IBSS (on an IBSS interface); this is called after all * information in bss_conf is set up and the beacon can be retrieved. A * channel context is bound before this is called. * @leave_ibss: Leave the IBSS again. * * @get_expected_throughput: extract the expected throughput towards the * specified station. The returned value is expressed in Kbps. It returns 0 * if the RC algorithm does not have proper data to provide. * * @get_txpower: get current maximum tx power (in dBm) based on configuration * and hardware limits. * * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver * is responsible for continually initiating channel-switching operations * and returning to the base channel for communication with the AP. The * driver receives a channel-switch request template and the location of * the switch-timing IE within the template as part of the invocation. * The template is valid only within the call, and the driver can * optionally copy the skb for further re-use. * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both * peers must be on the base channel when the call completes. * @tdls_recv_channel_switch: a TDLS channel-switch related frame (request or * response) has been received from a remote peer. The driver gets * parameters parsed from the incoming frame and may use them to continue * an ongoing channel-switch operation. In addition, a channel-switch * response template is provided, together with the location of the * switch-timing IE within the template. The skb can only be used within * the function call. * * @wake_tx_queue: Called when new packets have been added to the queue. * @sync_rx_queues: Process all pending frames in RSS queues. This is a * synchronization which is needed in case driver has in its RSS queues * pending frames that were received prior to the control path action * currently taken (e.g. disassociation) but are not processed yet. * * @start_nan: join an existing NAN cluster, or create a new one. * @stop_nan: leave the NAN cluster. * @nan_change_conf: change NAN configuration. The data in cfg80211_nan_conf * contains full new configuration and changes specify which parameters * are changed with respect to the last NAN config. * The driver gets both full configuration and the changed parameters since * some devices may need the full configuration while others need only the * changed parameters. * @add_nan_func: Add a NAN function. Returns 0 on success. The data in * cfg80211_nan_func must not be referenced outside the scope of * this call. * @del_nan_func: Remove a NAN function. The driver must call * ieee80211_nan_func_terminated() with * NL80211_NAN_FUNC_TERM_REASON_USER_REQUEST reason code upon removal. * @can_aggregate_in_amsdu: Called in order to determine if HW supports * aggregating two specific frames in the same A-MSDU. The relation * between the skbs should be symmetric and transitive. Note that while * skb is always a real frame, head may or may not be an A-MSDU. * @get_ftm_responder_stats: Retrieve FTM responder statistics, if available. * Statistics should be cumulative, currently no way to reset is provided. * * @start_pmsr: start peer measurement (e.g. FTM) (this call can sleep) * @abort_pmsr: abort peer measurement (this call can sleep) */ struct ieee80211_ops { void (*tx)(struct ieee80211_hw *hw, struct ieee80211_tx_control *control, struct sk_buff *skb); int (*start)(struct ieee80211_hw *hw); void (*stop)(struct ieee80211_hw *hw); #ifdef CONFIG_PM int (*suspend)(struct ieee80211_hw *hw, struct cfg80211_wowlan *wowlan); int (*resume)(struct ieee80211_hw *hw); void (*set_wakeup)(struct ieee80211_hw *hw, bool enabled); #endif int (*add_interface)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); int (*change_interface)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, enum nl80211_iftype new_type, bool p2p); void (*remove_interface)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); int (*config)(struct ieee80211_hw *hw, u32 changed); void (*bss_info_changed)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_bss_conf *info, u32 changed); int (*start_ap)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); void (*stop_ap)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); u64 (*prepare_multicast)(struct ieee80211_hw *hw, struct netdev_hw_addr_list *mc_list); void (*configure_filter)(struct ieee80211_hw *hw, unsigned int changed_flags, unsigned int *total_flags, u64 multicast); void (*config_iface_filter)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, unsigned int filter_flags, unsigned int changed_flags); int (*set_tim)(struct ieee80211_hw *hw, struct ieee80211_sta *sta, bool set); int (*set_key)(struct ieee80211_hw *hw, enum set_key_cmd cmd, struct ieee80211_vif *vif, struct ieee80211_sta *sta, struct ieee80211_key_conf *key); void (*update_tkip_key)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_key_conf *conf, struct ieee80211_sta *sta, u32 iv32, u16 *phase1key); void (*set_rekey_data)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct cfg80211_gtk_rekey_data *data); void (*set_default_unicast_key)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, int idx); int (*hw_scan)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_scan_request *req); void (*cancel_hw_scan)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); int (*sched_scan_start)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct cfg80211_sched_scan_request *req, struct ieee80211_scan_ies *ies); int (*sched_scan_stop)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); void (*sw_scan_start)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, const u8 *mac_addr); void (*sw_scan_complete)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); int (*get_stats)(struct ieee80211_hw *hw, struct ieee80211_low_level_stats *stats); void (*get_key_seq)(struct ieee80211_hw *hw, struct ieee80211_key_conf *key, struct ieee80211_key_seq *seq); int (*set_frag_threshold)(struct ieee80211_hw *hw, u32 value); int (*set_rts_threshold)(struct ieee80211_hw *hw, u32 value); int (*sta_add)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta); int (*sta_remove)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta); #ifdef CPTCFG_MAC80211_DEBUGFS void (*sta_add_debugfs)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta, struct dentry *dir); #endif void (*sta_notify)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, enum sta_notify_cmd, struct ieee80211_sta *sta); int (*sta_state)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta, enum ieee80211_sta_state old_state, enum ieee80211_sta_state new_state); void (*sta_pre_rcu_remove)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta); void (*sta_rc_update)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta, u32 changed); void (*sta_rate_tbl_update)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta); void (*sta_statistics)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta, struct station_info *sinfo); int (*conf_tx)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, u16 ac, const struct ieee80211_tx_queue_params *params); u64 (*get_tsf)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); void (*set_tsf)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, u64 tsf); void (*offset_tsf)(struct ieee80211_hw *hw, struct ieee80211_vif *vif, s64 offset); void (*reset_tsf)(struct ieee80211_hw *hw, struct ieee80211_vif *vif); int (*tx_last_beacon)(struct ieee80211_hw *hw); /** * @ampdu_action: * Perform a certain A-MPDU action. * The RA/TID combination determines the destination and TID we want * the ampdu action to be performed for.

It is possible to * specify a registration filter to register, for example, only for a * certain type of action frame. In particular with action frames, those * that userspace registers for will not be returned as unhandled by the * driver, so that the registered application has to take responsibility * for doing that. * * The type of frame that can be registered for is also dependent on the * driver and interface type. The frame types are advertised in wiphy * attributes so applications know what to expect. * * NOTE: When an interface changes type while registrations are active, * these registrations are ignored until the interface type is * changed again. This means that changing the interface type can * lead to a situation that couldn't otherwise be produced, but * any such registrations will be dormant in the sense that they * will not be serviced, i.e. they will not receive any frames. * * Frame transmission allows userspace to send for example the required * responses to action frames. It is subject to some sanity checking, * but many frames can be transmitted.

One reason for stopping the scan is if the hardware * does not support starting an association or a normal scan while running * a scheduled scan. This event is also sent when the * %NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface * is brought down while a scheduled scan was running. * * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation * or noise level * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to * NL80211_CMD_GET_SURVEY and on the "scan" multicast group) * * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry using %NL80211_ATTR_MAC * (for the BSSID), %NL80211_ATTR_PMKID, and optionally %NL80211_ATTR_PMK * (PMK is used for PTKSA derivation in case of FILS shared key offload) or * using %NL80211_ATTR_SSID, %NL80211_ATTR_FILS_CACHE_ID, * %NL80211_ATTR_PMKID, and %NL80211_ATTR_PMK in case of FILS * authentication where %NL80211_ATTR_FILS_CACHE_ID is the identifier * advertized by a FILS capable AP identifying the scope of PMKSA in an * ESS. * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC * (for the BSSID) and %NL80211_ATTR_PMKID or using %NL80211_ATTR_SSID, * %NL80211_ATTR_FILS_CACHE_ID, and %NL80211_ATTR_PMKID in case of FILS * authentication. * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries. * * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain * has been changed and provides details of the request information * that caused the change such as who initiated the regulatory request * (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx * (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if * the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or * %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain * set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is * %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on * to (%NL80211_ATTR_REG_ALPHA2). * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon * has been found while world roaming thus enabling active scan or * any mode of operation that initiates TX (beacons) on a channel * where we would not have been able to do either before. As an example * if you are world roaming (regulatory domain set to world or if your * driver is using a custom world roaming regulatory domain) and while * doing a passive scan on the 5 GHz band you find an AP there (if not * on a DFS channel) you will now be able to actively scan for that AP * or use AP mode on your card on that same channel. Note that this will * never be used for channels 1-11 on the 2 GHz band as they are always * enabled world wide. This beacon hint is only sent if your device had * either disabled active scanning or beaconing on a channel. We send to * userspace the wiphy on which we removed a restriction from * (%NL80211_ATTR_WIPHY) and the channel on which this occurred * before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER) * the beacon hint was processed. * * @NL80211_CMD_AUTHENTICATE: authentication request and notification. * This command is used both as a command (request to authenticate) and * as an event on the "mlme" multicast group indicating completion of the * authentication process. * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify * the SSID (mainly for association, but is included in authentication * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE * is used to specify the authentication type. %NL80211_ATTR_IE is used to * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs) * to be added to the frame. * When used as an event, this reports reception of an Authentication * frame in station and IBSS modes when the local MLME processed the * frame, i.e., it was for the local STA and was received in correct * state. This is similar to MLME-AUTHENTICATE.confirm primitive in the * MLME SAP interface (kernel providing MLME, userspace SME). The * included %NL80211_ATTR_FRAME attribute contains the management frame * (including both the header and frame body, but not FCS). This event is * also used to indicate if the authentication attempt timed out. In that * case the %NL80211_ATTR_FRAME attribute is replaced with a * %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which * pending authentication timed out). * @NL80211_CMD_ASSOCIATE: association request and notification; like * NL80211_CMD_AUTHENTICATE but for Association and Reassociation * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request, * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). The * %NL80211_ATTR_PREV_BSSID attribute is used to specify whether the * request is for the initial association to an ESS (that attribute not * included) or for reassociation within the ESS (that attribute is * included). * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like * NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication * primitives). * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like * NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives). * * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael * MIC (part of TKIP) failure; sent on the "mlme" multicast group; the * event includes %NL80211_ATTR_MAC to describe the source MAC address of * the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key * type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and * %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this * event matches with MLME-MICHAELMICFAILURE.indication() primitive * * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a * FREQ attribute (for the initial frequency if no peer can be found) * and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those * should be fixed rather than automatically determined. Can only be * executed on a network interface that is UP, and fixed BSSID/FREQ * may be rejected. Another optional parameter is the beacon interval, * given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not * given defaults to 100 TU (102.4ms). * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is * determined by the network interface. * * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute * to identify the device, and the TESTDATA blob attribute to pass through * to the driver. * * @NL80211_CMD_CONNECT: connection request and notification; this command * requests to connect to a specified network but without separating * auth and assoc steps. For this, you need to specify the SSID in a * %NL80211_ATTR_SSID attribute, and can optionally specify the association * IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP, * %NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT, * %NL80211_ATTR_CONTROL_PORT_ETHERTYPE, * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, * %NL80211_ATTR_CONTROL_PORT_OVER_NL80211, %NL80211_ATTR_MAC_HINT, and * %NL80211_ATTR_WIPHY_FREQ_HINT. * If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are * restrictions on BSS selection, i.e., they effectively prevent roaming * within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT * can be included to provide a recommendation of the initial BSS while * allowing the driver to roam to other BSSes within the ESS and also to * ignore this recommendation if the indicated BSS is not ideal. Only one * set of BSSID,frequency parameters is used (i.e., either the enforcing * %NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict * %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT). * %NL80211_ATTR_PREV_BSSID can be used to request a reassociation within * the ESS in case the device is already associated and an association with * a different BSS is desired. * Background scan period can optionally be * specified in %NL80211_ATTR_BG_SCAN_PERIOD, * if not specified default background scan configuration * in driver is used and if period value is 0, bg scan will be disabled. * This attribute is ignored if driver does not support roam scan. * It is also sent as an event, with the BSSID and response IEs when the * connection is established or failed to be established. This can be * determined by the %NL80211_ATTR_STATUS_CODE attribute (0 = success, * non-zero = failure). If %NL80211_ATTR_TIMED_OUT is included in the * event, the connection attempt failed due to not being able to initiate * authentication/association or not receiving a response from the AP. * Non-zero %NL80211_ATTR_STATUS_CODE value is indicated in that case as * well to remain backwards compatible. * When establishing a security association, drivers that support 4 way * handshake offload should send %NL80211_CMD_PORT_AUTHORIZED event when * the 4 way handshake is completed successfully. * @NL80211_CMD_ROAM: Notification indicating the card/driver roamed by itself. * When a security association was established with the new AP (e.g. if * the FT protocol was used for roaming or the driver completed the 4 way * handshake), this event should be followed by an * %NL80211_CMD_PORT_AUTHORIZED event. * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify * userspace that a connection was dropped by the AP or due to other * reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and * %NL80211_ATTR_REASON_CODE attributes are used. * * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices * associated with this wiphy must be down and will follow. * * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified * channel for the specified amount of time. This can be used to do * off-channel operations like transmit a Public Action frame and wait for * a response while being associated to an AP on another channel. * %NL80211_ATTR_IFINDEX is used to specify which interface (and thus * radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the * frequency for the operation. * %NL80211_ATTR_DURATION is used to specify the duration in milliseconds * to remain on the channel. This command is also used as an event to * notify when the requested duration starts (it may take a while for the * driver to schedule this time due to other concurrent needs for the * radio). * When called, this operation returns a cookie (%NL80211_ATTR_COOKIE) * that will be included with any events pertaining to this request; * the cookie is also used to cancel the request. * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a * pending remain-on-channel duration if the desired operation has been * completed prior to expiration of the originally requested duration. * %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the * radio. The %NL80211_ATTR_COOKIE attribute must be given as well to * uniquely identify the request. * This command is also used as an event to notify when a requested * remain-on-channel duration has expired. * * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX * rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface * and @NL80211_ATTR_TX_RATES the set of allowed rates. * * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames * (via @NL80211_CMD_FRAME) for processing in userspace. This command * requires an interface index, a frame type attribute (optional for * backward compatibility reasons, if not given assumes action frames) * and a match attribute containing the first few bytes of the frame * that should match, e.g. a single byte for only a category match or * four bytes for vendor frames including the OUI. The registration * cannot be dropped, but is removed automatically when the netlink * socket is closed. Multiple registrations can be made. * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for * backward compatibility * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This * command is used both as a request to transmit a management frame and * as an event indicating reception of a frame that was not processed in * kernel code, but is for us (i.e., which may need to be processed in a * user space application). %NL80211_ATTR_FRAME is used to specify the * frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used * to indicate on which channel the frame is to be transmitted or was * received. If this channel is not the current channel (remain-on-channel * or the operational channel) the device will switch to the given channel * and transmit the frame, optionally waiting for a response for the time * specified using %NL80211_ATTR_DURATION. When called, this operation * returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the * TX status event pertaining to the TX request. * %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the * management frames at CCK rate or not in 2GHz band. * %NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA * counters which will be updated to the current value. This attribute * is used during CSA period. * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this * command may be used with the corresponding cookie to cancel the wait * time if it is known that it is no longer necessary. * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility. * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame * transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies * the TX command and %NL80211_ATTR_FRAME includes the contents of the * frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged * the frame. * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for * backward compatibility. * * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE * * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command * is used to configure connection quality monitoring notification trigger * levels. * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This * command is used as an event to indicate the that a trigger level was * reached. * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ * and the attributes determining channel width) the given interface * (identifed by %NL80211_ATTR_IFINDEX) shall operate on. * In case multiple channels are supported by the device, the mechanism * with which it switches channels is implementation-defined. * When a monitor interface is given, it can only switch channel while * no other interfaces are operating to avoid disturbing the operation * of any other interfaces, and other interfaces will again take * precedence when they are used. * * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface. * * @NL80211_CMD_SET_MULTICAST_TO_UNICAST: Configure if this AP should perform * multicast to unicast conversion. When enabled, all multicast packets * with ethertype ARP, IPv4 or IPv6 (possibly within an 802.1Q header) * will be sent out to each station once with the destination (multicast) * MAC address replaced by the station's MAC address. Note that this may * break certain expectations of the receiver, e.g. the ability to drop * unicast IP packets encapsulated in multicast L2 frames, or the ability * to not send destination unreachable messages in such cases. * This can only be toggled per BSS. Configure this on an interface of * type %NL80211_IFTYPE_AP. It applies to all its VLAN interfaces * (%NL80211_IFTYPE_AP_VLAN), except for those in 4addr (WDS) mode. * If %NL80211_ATTR_MULTICAST_TO_UNICAST_ENABLED is not present with this * command, the feature is disabled. * * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial * mesh config parameters may be given. * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the * network is determined by the network interface. * * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame * notification. This event is used to indicate that an unprotected * deauthentication frame was dropped when MFP is in use. * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame * notification. This event is used to indicate that an unprotected * disassociation frame was dropped when MFP is in use. * * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a * beacon or probe response from a compatible mesh peer. This is only * sent while no station information (sta_info) exists for the new peer * candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH, * @NL80211_MESH_SETUP_USERSPACE_AMPE, or * @NL80211_MESH_SETUP_USERSPACE_MPM is set. On reception of this * notification, userspace may decide to create a new station * (@NL80211_CMD_NEW_STATION). To stop this notification from * reoccurring, the userspace authentication daemon may want to create the * new station with the AUTHENTICATED flag unset and maybe change it later * depending on the authentication result. * * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings. * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings. * Since wireless is more complex than wired ethernet, it supports * various triggers. These triggers can be configured through this * command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For * more background information, see * http://wireless.kernel.org/en/users/Documentation/WoWLAN. * The @NL80211_CMD_SET_WOWLAN command can also be used as a notification * from the driver reporting the wakeup reason. In this case, the * @NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason * for the wakeup, if it was caused by wireless. If it is not present * in the wakeup notification, the wireless device didn't cause the * wakeup but reports that it was woken up. * * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver * the necessary information for supporting GTK rekey offload. This * feature is typically used during WoWLAN. The configuration data * is contained in %NL80211_ATTR_REKEY_DATA (which is nested and * contains the data in sub-attributes). After rekeying happened, * this command may also be sent by the driver as an MLME event to * inform userspace of the new replay counter. * * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace * of PMKSA caching dandidates. * * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup). * In addition, this can be used as an event to request userspace to take * actions on TDLS links (set up a new link or tear down an existing one). * In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested * operation, %NL80211_ATTR_MAC contains the peer MAC address, and * %NL80211_ATTR_REASON_CODE the reason code to be used (only with * %NL80211_TDLS_TEARDOWN). * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The * %NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be * sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as * 802.11 management frames, while TDLS action codes (802.11-2012 * 8.5.13.1) will be encapsulated and sent as data frames. The currently * supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES * and the currently supported TDLS actions codes are given in * &enum ieee80211_tdls_actioncode. * * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP * (or GO) interface (i.e. hostapd) to ask for unexpected frames to * implement sending deauth to stations that send unexpected class 3 * frames. Also used as the event sent by the kernel when such a frame * is received. * For the event, the %NL80211_ATTR_MAC attribute carries the TA and * other attributes like the interface index are present. * If used as the command it must have an interface index and you can * only unsubscribe from the event by closing the socket. Subscription * is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events. * * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the * associated station identified by %NL80211_ATTR_MAC sent a 4addr frame * and wasn't already in a 4-addr VLAN. The event will be sent similarly * to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener. * * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface * by sending a null data frame to it and reporting when the frame is * acknowleged. This is used to allow timing out inactive clients. Uses * %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a * direct reply with an %NL80211_ATTR_COOKIE that is later used to match * up the event with the request. The event includes the same data and * has %NL80211_ATTR_ACK set if the frame was ACKed. * * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from * other BSSes when any interfaces are in AP mode. This helps implement * OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME * messages. Note that per PHY only one application may register. * * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether * No Acknowledgement Policy should be applied. * * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels * independently of the userspace SME, send this event indicating * %NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the * attributes determining channel width. This indication may also be * sent when a remotely-initiated switch (e.g., when a STA receives a CSA * from the remote AP) is completed; * * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch * has been started on an interface, regardless of the initiator * (ie. whether it was requested from a remote device or * initiated on our own). It indicates that * %NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ * after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's. The userspace may * decide to react to this indication by requesting other * interfaces to change channel as well. * * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by * its %NL80211_ATTR_WDEV identifier. It must have been created with * %NL80211_CMD_NEW_INTERFACE previously. After it has been started, the * P2P Device can be used for P2P operations, e.g. remain-on-channel and * public action frame TX. * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by * its %NL80211_ATTR_WDEV identifier. * * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to * notify userspace that AP has rejected the connection request from a * station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON * is used for this. * * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames * for IBSS or MESH vif. * * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control. * This is to be used with the drivers advertising the support of MAC * address based access control. List of MAC addresses is passed in * %NL80211_ATTR_MAC_ADDRS and ACL policy is passed in * %NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it * is not already done. The new list will replace any existing list. Driver * will clear its ACL when the list of MAC addresses passed is empty. This * command is used in AP/P2P GO mode. Driver has to make sure to clear its * ACL list during %NL80211_CMD_STOP_AP. * * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once * a radar is detected or the channel availability scan (CAC) has finished * or was aborted, or a radar was detected, usermode will be notified with * this event. This command is also used to notify userspace about radars * while operating on this channel. * %NL80211_ATTR_RADAR_EVENT is used to inform about the type of the * event. * * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features, * i.e. features for the nl80211 protocol rather than device features. * Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap. * * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition * Information Element to the WLAN driver * * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver * to the supplicant. This will carry the target AP's MAC address along * with the relevant Information Elements. This event is used to report * received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE). * * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running * a critical protocol that needs more reliability in the connection to * complete. * * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can * return back to normal. * * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules. * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules. * * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the * the new channel information (Channel Switch Announcement - CSA) * in the beacon for some time (as defined in the * %NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the * new channel. Userspace provides the new channel information (using * %NL80211_ATTR_WIPHY_FREQ and the attributes determining channel * width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform * other station that transmission must be blocked until the channel * switch is complete. * * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified * by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in * %NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in * %NL80211_ATTR_VENDOR_DATA. * For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is * used in the wiphy data as a nested attribute containing descriptions * (&struct nl80211_vendor_cmd_info) of the supported vendor commands. * This may also be sent as an event with the same attributes. * * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values. * The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If * that attribute is not included, QoS mapping is disabled. Since this * QoS mapping is relevant for IP packets, it is only valid during an * association. This is cleared on disassociation and AP restart. * * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given * %NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO * and %NL80211_ATTR_ADMITTED_TIME parameters. * Note that the action frame handshake with the AP shall be handled by * userspace via the normal management RX/TX framework, this only sets * up the TX TS in the driver/device. * If the admitted time attribute is not added then the request just checks * if a subsequent setup could be successful, the intent is to use this to * avoid setting up a session with the AP when local restrictions would * make that impossible. However, the subsequent "real" setup may still * fail even if the check was successful. * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID * and %NL80211_ATTR_MAC parameters. It isn't necessary to call this * before removing a station entry entirely, or before disassociating * or similar, cleanup will happen in the driver/device in this case. * * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to * destination %NL80211_ATTR_MAC on the interface identified by * %NL80211_ATTR_IFINDEX. * * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and * bandwidth of a channel must be given. * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the * network is determined by the network interface. * * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer, * identified by the %NL80211_ATTR_MAC parameter. A target channel is * provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining * channel width/type. The target operating class is given via * %NL80211_ATTR_OPER_CLASS. * The driver is responsible for continually initiating channel-switching * operations and returning to the base channel for communication with the * AP. * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS * peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel * when this command completes. * * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used * as an event to indicate changes for devices with wiphy-specific regdom * management. * * @NL80211_CMD_ABORT_SCAN: Stop an ongoing scan. Returns -ENOENT if a scan is * not running. The driver indicates the status of the scan through * cfg80211_scan_done(). * * @NL80211_CMD_START_NAN: Start NAN operation, identified by its * %NL80211_ATTR_WDEV interface. This interface must have been * previously created with %NL80211_CMD_NEW_INTERFACE. After it * has been started, the NAN interface will create or join a * cluster. This command must have a valid * %NL80211_ATTR_NAN_MASTER_PREF attribute and optional * %NL80211_ATTR_BANDS, %NL80211_ATTR_NAN_CDW_2G and * %NL80211_ATTR_NAN_CDW_5G attributes. If %NL80211_ATTR_BANDS is * omitted or set to 0, it means don't-care and the device will * decide what to use. After this command NAN functions can be * added. * @NL80211_CMD_STOP_NAN: Stop the NAN operation, identified by * its %NL80211_ATTR_WDEV interface. * @NL80211_CMD_ADD_NAN_FUNCTION: Add a NAN function. The function is defined * with %NL80211_ATTR_NAN_FUNC nested attribute. When called, this * operation returns the strictly positive and unique instance id * (%NL80211_ATTR_NAN_FUNC_INST_ID) and a cookie (%NL80211_ATTR_COOKIE) * of the function upon success. * Since instance ID's can be re-used, this cookie is the right * way to identify the function. This will avoid races when a termination * event is handled by the user space after it has already added a new * function that got the same instance id from the kernel as the one * which just terminated. * This cookie may be used in NAN events even before the command * returns, so userspace shouldn't process NAN events until it processes * the response to this command. * Look at %NL80211_ATTR_SOCKET_OWNER as well. * @NL80211_CMD_DEL_NAN_FUNCTION: Delete a NAN function by cookie. * This command is also used as a notification sent when a NAN function is * terminated. This will contain a %NL80211_ATTR_NAN_FUNC_INST_ID * and %NL80211_ATTR_COOKIE attributes. * @NL80211_CMD_CHANGE_NAN_CONFIG: Change current NAN * configuration. NAN must be operational (%NL80211_CMD_START_NAN * was executed). It must contain at least one of the following * attributes: %NL80211_ATTR_NAN_MASTER_PREF, * %NL80211_ATTR_BANDS, %NL80211_ATTR_NAN_CDW_2G, %NL80211_ATTR_NAN_CDW_5G. * If %NL80211_ATTR_BANDS is present but set to zero, the configuration is * changed to don't-care (i.e. the device can decide what to do). * @NL80211_CMD_NAN_FUNC_MATCH: Notification sent when a match is reported. * This will contain a %NL80211_ATTR_NAN_MATCH nested attribute and * %NL80211_ATTR_COOKIE. * * @NL80211_CMD_UPDATE_CONNECT_PARAMS: Update one or more connect parameters * for subsequent roaming cases if the driver or firmware uses internal * BSS selection. This command can be issued only while connected and it * does not result in a change for the current association. Currently, * only the %NL80211_ATTR_IE data is used and updated with this command. * * @NL80211_CMD_SET_PMK: For offloaded 4-Way handshake, set the PMK or PMK-R0 * for the given authenticator address (specified with %NL80211_ATTR_MAC). * When %NL80211_ATTR_PMKR0_NAME is set, %NL80211_ATTR_PMK specifies the * PMK-R0, otherwise it specifies the PMK. * @NL80211_CMD_DEL_PMK: For offloaded 4-Way handshake, delete the previously * configured PMK for the authenticator address identified by * %NL80211_ATTR_MAC. * @NL80211_CMD_PORT_AUTHORIZED: An event that indicates that the 4 way * handshake was completed successfully by the driver. The BSSID is * specified with %NL80211_ATTR_MAC. Drivers that support 4 way handshake * offload should send this event after indicating 802.11 association with * %NL80211_CMD_CONNECT or %NL80211_CMD_ROAM. If the 4 way handshake failed * %NL80211_CMD_DISCONNECT should be indicated instead. * * @NL80211_CMD_CONTROL_PORT_FRAME: Control Port (e.g. PAE) frame TX request * and RX notification. This command is used both as a request to transmit * a control port frame and as a notification that a control port frame * has been received. %NL80211_ATTR_FRAME is used to specify the * frame contents. The frame is the raw EAPoL data, without ethernet or * 802.11 headers. * When used as an event indication %NL80211_ATTR_CONTROL_PORT_ETHERTYPE, * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT and %NL80211_ATTR_MAC are added * indicating the protocol type of the received frame; whether the frame * was received unencrypted and the MAC address of the peer respectively. * * @NL80211_CMD_RELOAD_REGDB: Request that the regdb firmware file is reloaded. * * @NL80211_CMD_EXTERNAL_AUTH: This interface is exclusively defined for host * drivers that do not define separate commands for authentication and * association, but rely on user space for the authentication to happen. * This interface acts both as the event request (driver to user space) * to trigger the authentication and command response (userspace to * driver) to indicate the authentication status. * * User space uses the %NL80211_CMD_CONNECT command to the host driver to * trigger a connection. The host driver selects a BSS and further uses * this interface to offload only the authentication part to the user * space. Authentication frames are passed between the driver and user * space through the %NL80211_CMD_FRAME interface. Host driver proceeds * further with the association after getting successful authentication * status. User space indicates the authentication status through * %NL80211_ATTR_STATUS_CODE attribute in %NL80211_CMD_EXTERNAL_AUTH * command interface. In case of success, user space also includes the * derived PMK and PMKID through %NL80211_ATTR_PMK and * %NL80211_ATTR_PMKID. * * Host driver reports this status on an authentication failure to the * user space through the connect result as the user space would have * initiated the connection through the connect request. * * @NL80211_CMD_STA_OPMODE_CHANGED: An event that notify station's * ht opmode or vht opmode changes using any of %NL80211_ATTR_SMPS_MODE, * %NL80211_ATTR_CHANNEL_WIDTH,%NL80211_ATTR_NSS attributes with its * address(specified in %NL80211_ATTR_MAC). * * @NL80211_CMD_GET_FTM_RESPONDER_STATS: Retrieve FTM responder statistics, in * the %NL80211_ATTR_FTM_RESPONDER_STATS attribute. * * @NL80211_CMD_PEER_MEASUREMENT_START: start a (set of) peer measurement(s) * with the given parameters, which are encapsulated in the nested * %NL80211_ATTR_PEER_MEASUREMENTS attribute. Optionally, MAC address * randomization may be enabled and configured by specifying the * %NL80211_ATTR_MAC and %NL80211_ATTR_MAC_MASK attributes. * If a timeout is requested, use the %NL80211_ATTR_TIMEOUT attribute. * A u64 cookie for further %NL80211_ATTR_COOKIE use is is returned in * the netlink extended ack message. * * To cancel a measurement, close the socket that requested it. * * Measurement results are reported to the socket that requested the * measurement using @NL80211_CMD_PEER_MEASUREMENT_RESULT when they * become available, so applications must ensure a large enough socket * buffer size. * * Depending on driver support it may or may not be possible to start * multiple concurrent measurements. * @NL80211_CMD_PEER_MEASUREMENT_RESULT: This command number is used for the * result notification from the driver to the requesting socket. * @NL80211_CMD_PEER_MEASUREMENT_COMPLETE: Notification only, indicating that * the measurement completed, using the measurement cookie * (%NL80211_ATTR_COOKIE). * * @NL80211_CMD_NOTIFY_RADAR: Notify the kernel that a radar signal was * detected and reported by a neighboring device on the channel * indicated by %NL80211_ATTR_WIPHY_FREQ and other attributes * determining the width and type. * * @NL80211_CMD_MAX: highest used command number * @__NL80211_CMD_AFTER_LAST: internal use */ enum nl80211_commands { /* don't change the order or add anything between, this is ABI! */ NL80211_CMD_UNSPEC, NL80211_CMD_GET_WIPHY, /* can dump */ NL80211_CMD_SET_WIPHY, NL80211_CMD_NEW_WIPHY, NL80211_CMD_DEL_WIPHY, NL80211_CMD_GET_INTERFACE, /* can dump */ NL80211_CMD_SET_INTERFACE, NL80211_CMD_NEW_INTERFACE, NL80211_CMD_DEL_INTERFACE, NL80211_CMD_GET_KEY, NL80211_CMD_SET_KEY, NL80211_CMD_NEW_KEY, NL80211_CMD_DEL_KEY, NL80211_CMD_GET_BEACON, NL80211_CMD_SET_BEACON, NL80211_CMD_START_AP, NL80211_CMD_NEW_BEACON = NL80211_CMD_START_AP, NL80211_CMD_STOP_AP, NL80211_CMD_DEL_BEACON = NL80211_CMD_STOP_AP, NL80211_CMD_GET_STATION, NL80211_CMD_SET_STATION, NL80211_CMD_NEW_STATION, NL80211_CMD_DEL_STATION, NL80211_CMD_GET_MPATH, NL80211_CMD_SET_MPATH, NL80211_CMD_NEW_MPATH, NL80211_CMD_DEL_MPATH, NL80211_CMD_SET_BSS, NL80211_CMD_SET_REG, NL80211_CMD_REQ_SET_REG, NL80211_CMD_GET_MESH_CONFIG, NL80211_CMD_SET_MESH_CONFIG, NL80211_CMD_SET_MGMT_EXTRA_IE /* reserved;

If an antenna is not selected in this * bitmap the hardware is not allowed to transmit on this antenna. * * Each bit represents one antenna, starting with antenna 1 at the first * bit. Depending on which antennas are selected in the bitmap, 802.11n * drivers can derive which chainmasks to use (if all antennas belonging to * a particular chain are disabled this chain should be disabled) and if * a chain has diversity antennas wether diversity should be used or not. * HT capabilities (STBC, TX Beamforming, Antenna selection) can be * derived from the available chains after applying the antenna mask. * Non-802.11n drivers can derive wether to use diversity or not. * Drivers may reject configurations or RX/TX mask combinations they cannot * support by returning -EINVAL. * * @NL80211_ATTR_WIPHY_ANTENNA_RX: Bitmap of allowed antennas for receiving. * This can be used to mask out antennas which are not attached or should * not be used for receiving.

Now lxdialog is a bit * smarter and works more like other menu systems (just have a look at * it). * * *) Formerly if I selected something my scrolling would be broken because * lxdialog is re-invoked by the Menuconfig shell script, can't * remember the last scrolling position, and just sets it so that the * cursor is at the bottom of the box. Now it writes the temporary file * lxdialog.scrltmp which contains this information. The file is * deleted by lxdialog if the user leaves a submenu or enters a new * one, but it would be nice if Menuconfig could make another "rm -f" * just to be sure. Just try it out - you will recognise a difference! * * [ 1998-06-14 ] * * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files * and menus change their size on the fly. * * *) If for some reason the last scrolling position is not saved by * lxdialog, it sets the scrolling so that the selected item is in the * middle of the menu box, not at the bottom. * * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net) * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus. * This fixes a bug in Menuconfig where using ' ' to descend into menus * would leave mis-synchronized lxdialog.scrltmp files lying around, * fscanf would read in 'scroll', and eventually that value would get used. */ #include "dialog.h" static int menu_width, item_x;

The reason is that some programs need kernel networking support even when running on a stand-alone machine that isn't connected to any other computer. If you are upgrading from an older kernel, you should consider updating your networking tools too because changes in the kernel and the tools often go hand in hand. The tools are contained in the package net-tools, the location and version number of which are given in . For a general introduction to Linux networking, it is highly recommended to read the NET-HOWTO, available from . if NET config WANT_COMPAT_NETLINK_MESSAGES bool help This option can be selected by other options that need compat netlink messages. config COMPAT_NETLINK_MESSAGES def_bool y depends on COMPAT depends on WEXT_CORE || WANT_COMPAT_NETLINK_MESSAGES help This option makes it possible to send different netlink messages to tasks depending on whether the task is a compat task or not. To achieve this, you need to set skb_shinfo(skb)->frag_list to the compat skb before sending the skb, the netlink code will sort out which message to actually pass to the task. Newly written code should NEVER need this option but do compat-independent messages instead! config NET_INGRESS bool config NET_EGRESS bool config SKB_EXTENSIONS bool menu "Networking options" source "net/packet/Kconfig" source "net/unix/Kconfig" source "net/tls/Kconfig" source "net/xfrm/Kconfig" source "net/iucv/Kconfig" source "net/smc/Kconfig" source "net/xdp/Kconfig" config INET bool "TCP/IP networking" select CRYPTO select CRYPTO_AES ---help--- These are the protocols used on the Internet and on most local Ethernets. It is highly recommended to say Y here (this will enlarge your kernel by about 400 KB), since some programs (e.g. the X window system) use TCP/IP even if your machine is not connected to any other computer. You will get the so-called loopback device which allows you to ping yourself (great fun, that!). For an excellent introduction to Linux networking, please read the Linux Networking HOWTO, available from . If you say Y here and also to "/proc file system support" and "Sysctl support" below, you can change various aspects of the behavior of the TCP/IP code by writing to the (virtual) files in /proc/sys/net/ipv4/*; the options are explained in the file .

This option adds some overhead in the transmit and receive paths. If you are unsure how to answer this question, answer N. menuconfig NETFILTER bool "Network packet filtering framework (Netfilter)" ---help--- Netfilter is a framework for filtering and mangling network packets that pass through your Linux box. The most common use of packet filtering is to run your Linux box as a firewall protecting a local network from the Internet. The type of firewall provided by this kernel support is called a "packet filter", which means that it can reject individual network packets based on type, source, destination etc. The other kind of firewall, a "proxy-based" one, is more secure but more intrusive and more bothersome to set up; it inspects the network traffic much more closely, modifies it and has knowledge about the higher level protocols, which a packet filter lacks. Moreover, proxy-based firewalls often require changes to the programs running on the local clients. Proxy-based firewalls don't need support by the kernel, but they are often combined with a packet filter, which only works if you say Y here. You should also say Y here if you intend to use your Linux box as the gateway to the Internet for a local network of machines without globally valid IP addresses. This is called "masquerading": if one of the computers on your local network wants to send something to the outside, your box can "masquerade" as that computer, i.e. it forwards the traffic to the intended outside destination, but modifies the packets to make it look like they came from the firewall box itself. It works both ways: if the outside host replies, the Linux box will silently forward the traffic to the correct local computer. This way, the computers on your local net are completely invisible to the outside world, even though they can reach the outside and can receive replies. It is even possible to run globally visible servers from within a masqueraded local network using a mechanism called portforwarding. Masquerading is also often called NAT (Network Address Translation). Another use of Netfilter is in transparent proxying: if a machine on the local network tries to connect to an outside host, your Linux box can transparently forward the traffic to a local server, typically a caching proxy server. Yet another use of Netfilter is building a bridging firewall. Using a bridge with Network packet filtering enabled makes iptables "see" the bridged traffic. For filtering on the lower network and Ethernet protocols over the bridge, use ebtables (under bridge netfilter configuration). Various modules exist for netfilter which replace the previous masquerading (ipmasqadm), packet filtering (ipchains), transparent proxying, and portforwarding mechanisms. Please see under "iptables" for the location of these packages. if NETFILTER config NETFILTER_ADVANCED bool "Advanced netfilter configuration" depends on NETFILTER default y help If you say Y here you can select between all the netfilter modules.

It also allows live migration of VMs with direct attached VFs by failing over to the paravirtual datapath when the VF is unplugged. endif # if NET # Used by archs to tell that they support BPF JIT compiler plus which flavour. # Only one of the two can be selected for a specific arch since eBPF JIT supersedes # the cBPF JIT. # Classic BPF JIT (cBPF) config HAVE_CBPF_JIT bool # Extended BPF JIT (eBPF) config HAVE_EBPF_JIT bool backport-iwlwifi-dkms-7906/net/Makefile000066400000000000000000000050011351064634500201230ustar00rootroot00000000000000# SPDX-License-Identifier: GPL-2.0 # # Makefile for the linux networking. # # 2 Sep 2000, Christoph Hellwig # Rewritten to use lists instead of if-statements. # obj-$(CONFIG_NET) := socket.o core/ tmp-$(CONFIG_COMPAT) := compat.o obj-$(CONFIG_NET) += $(tmp-y) # LLC has to be linked before the files in net/802/ obj-$(CONFIG_LLC) += llc/ obj-$(CONFIG_NET) += ethernet/ 802/ sched/ netlink/ bpf/ obj-$(CONFIG_NETFILTER) += netfilter/ obj-$(CONFIG_INET) += ipv4/ obj-$(CONFIG_TLS) += tls/ obj-$(CONFIG_XFRM) += xfrm/ obj-$(CONFIG_UNIX) += unix/ obj-$(CONFIG_NET) += ipv6/ obj-$(CONFIG_BPFILTER) += bpfilter/ obj-$(CONFIG_PACKET) += packet/ obj-$(CONFIG_NET_KEY) += key/ obj-$(CONFIG_BRIDGE) += bridge/ obj-$(CONFIG_NET_DSA) += dsa/ obj-$(CONFIG_ATALK) += appletalk/ obj-$(CONFIG_X25) += x25/ obj-$(CONFIG_LAPB) += lapb/ obj-$(CONFIG_NETROM) += netrom/ obj-$(CONFIG_ROSE) += rose/ obj-$(CONFIG_AX25) += ax25/ obj-$(CONFIG_CAN) += can/ obj-$(CONFIG_BT) += bluetooth/ obj-$(CONFIG_SUNRPC) += sunrpc/ obj-$(CONFIG_AF_RXRPC) += rxrpc/ obj-$(CONFIG_AF_KCM) += kcm/ obj-$(CONFIG_STREAM_PARSER) += strparser/ obj-$(CONFIG_ATM) += atm/ obj-$(CONFIG_L2TP) += l2tp/ obj-$(CONFIG_DECNET) += decnet/ obj-$(CONFIG_PHONET) += phonet/ ifneq ($(CONFIG_VLAN_8021Q),) obj-y += 8021q/ endif obj-$(CONFIG_IP_DCCP) += dccp/ obj-$(CONFIG_IP_SCTP) += sctp/ obj-$(CONFIG_RDS) += rds/ obj-$(CPTCFG_WIRELESS) += wireless/ obj-$(CPTCFG_MAC80211) += mac80211/ obj-$(CONFIG_TIPC) += tipc/ obj-$(CONFIG_NETLABEL) += netlabel/ obj-$(CONFIG_IUCV) += iucv/ obj-$(CONFIG_SMC) += smc/ obj-$(CONFIG_RFKILL) += rfkill/ obj-$(CONFIG_NET_9P) += 9p/ obj-$(CONFIG_CAIF) += caif/ ifneq ($(CONFIG_DCB),) obj-y += dcb/ endif obj-$(CONFIG_6LOWPAN) += 6lowpan/ obj-$(CONFIG_IEEE802154) += ieee802154/ obj-$(CONFIG_MAC802154) += mac802154/ ifeq ($(CONFIG_NET),y) obj-$(CONFIG_SYSCTL) += sysctl_net.o endif obj-$(CONFIG_WIMAX) += wimax/ obj-$(CONFIG_DNS_RESOLVER) += dns_resolver/ obj-$(CONFIG_CEPH_LIB) += ceph/ obj-$(CONFIG_BATMAN_ADV) += batman-adv/ obj-$(CONFIG_NFC) += nfc/ obj-$(CONFIG_PSAMPLE) += psample/ obj-$(CONFIG_NET_IFE) += ife/ obj-$(CONFIG_OPENVSWITCH) += openvswitch/ obj-$(CONFIG_VSOCKETS) += vmw_vsock/ obj-$(CONFIG_MPLS) += mpls/ obj-$(CONFIG_NET_NSH) += nsh/ obj-$(CONFIG_HSR) += hsr/ ifneq ($(CONFIG_NET_SWITCHDEV),) obj-y += switchdev/ endif ifneq ($(CONFIG_NET_L3_MASTER_DEV),) obj-y += l3mdev/ endif obj-$(CONFIG_QRTR) += qrtr/ obj-$(CONFIG_NET_NCSI) += ncsi/ obj-$(CONFIG_XDP_SOCKETS) += xdp/ backport-iwlwifi-dkms-7906/net/mac80211/000077500000000000000000000000001351064634500176235ustar00rootroot00000000000000backport-iwlwifi-dkms-7906/net/mac80211/Kconfig000066400000000000000000000226271351064634500211370ustar00rootroot00000000000000config MAC80211 tristate "Generic IEEE 802.11 Networking Stack (mac80211)" depends on m depends on CFG80211 depends on CRYPTO depends on CRYPTO_ARC4 depends on CRYPTO_AES depends on CRYPTO_CCM depends on CRYPTO_GCM depends on CRYPTO_CMAC depends on CRC32 ---help--- This option enables the hardware independent IEEE 802.11 networking stack. comment "CFG80211 needs to be enabled for MAC80211" depends on CFG80211=n if MAC80211 != n config MAC80211_HAS_RC bool config MAC80211_RC_MINSTREL bool "Minstrel" if EXPERT select MAC80211_HAS_RC default y ---help--- This option enables the 'minstrel' TX rate control algorithm choice prompt "Default rate control algorithm" depends on MAC80211_HAS_RC default MAC80211_RC_DEFAULT_MINSTREL ---help--- This option selects the default rate control algorithm mac80211 will use.

Some options may still be under heavy development and for whatever reason regulatory compliance has not or cannot yet be verified. Regulatory verification may at times only be possible until you have the final system in place.

This feature has an inherent dependency on userspace features which must have been properly tested and as such is not enabled by default. A relaxation feature example is allowing the operation of a P2P group owner (GO) on channels marked with NO_IR if there is an additional BSS interface which associated to an AP which userspace assumes or confirms to be an authorized master, i.e., with radar detection support and DFS capabilities. However, note that in order to not create daisy chain scenarios, this relaxation is not allowed in cases where the BSS client is associated to P2P GO and in addition the P2P GO instantiated on a channel due to this relaxation should not allow connection from non P2P clients. The regulatory core will apply these relaxations only for drivers that support this feature by declaring the appropriate channel flags and capabilities in their registration flow. config CFG80211_DEFAULT_PS bool "enable powersave by default" default y help This option enables powersave mode by default.

Read C language source or header FILEs, extract embedded documentation comments, and print formatted documentation to standard output. The documentation comments are identified by "/**" opening comment mark. See Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax. Output format selection (mutually exclusive): -docbook Output DocBook format. -html Output HTML format. -html5 Output HTML5 format. -list Output symbol list format. This is for use by docproc. -man Output troff manual page format. This is the default. -rst Output reStructuredText format. -text Output plain text format. Output selection (mutually exclusive): -export Only output documentation for symbols that have been exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() in any input FILE or -export-file FILE. -internal Only output documentation for symbols that have NOT been exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() in any input FILE or -export-file FILE. -function NAME Only output documentation for the given function(s) or DOC: section title(s). All other functions and DOC: sections are ignored. May be specified multiple times. -nofunction NAME Do NOT output documentation for the given function(s); only output documentation for the other functions and DOC: sections. May be specified multiple times. Output selection modifiers: -no-doc-sections Do not output DOC: sections. -enable-lineno Enable output of #define LINENO lines. Only works with reStructuredText format. -export-file FILE Specify an additional FILE in which to look for EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with -export or -internal. May be specified multiple times. Other parameters: -v Verbose output, more warnings and other information. -h Print this help.

Instead of the function name you must write the name # of the declaration; the struct/union/enum/typedef must always precede # the name.

When documenting kernel functions you # should document the "Context:" of the function, e.g. whether the functions # can be called form interrupts.
