This section defines extensions to the FTP specification STD 9, RFC 959, @ref rfc959 "FILE TRANSFER PROTOCOL (FTP)" (October 1985) These extensions provide striped data transfer, parallel data transfer, extended data transfer, data buffer size configuration, and data channel authentication. The following new commands are introduced in this specification - @ref sec_SPAS "Striped Passive (SPAS)" - @ref sec_SPOR "Striped Data Port (SPOR)" - @ref sec_ERET "Extended Retrieve (ERET)" - @ref sec_ESTO "Extended Store (ESTO)" - @ref sec_SBUF "Set Data Buffer Size (SBUF)" - @ref sec_DCAU "Data Channel Authentication Mode (DCAU)"

A new transfer mode (@ref mode_e "extended-block mode") is introduced for parallel and striped data transfers. Also, a set of extension @ref sec_OPTS "options to RETR" are added to control striped data layout and parallelism. The following new feature names are to be included in the FTP server's response to FEAT if it implements the following sets of functionality @par PARALLEL The server supports the SPOR, SPAS, the RETR options mentioned above, and extended block mode. @par ESTO The server implements the ESTO command as described in this document. @par ERET The server implements the ERET command as described in this document. @par SBUF The server implements the SBUF command as described in this document. @par DCAU The server implements the DCAU command as described in this document, including the requirement that data channels are authenticated by default, if @ref rfc2228 "RFC 2228" authentication is used to establish the control channel.

@section term Terminology @par Parallel transfer From a single data server, splitting file data for transfer over multiple data connections. @par Striped transfer Distributing a file's data over multiple independent data nodes, and transerring over multiple data connections. @par Data Node In a striped data transfer, a data node is one of the stripe destinations returned in the SPAS command, or one of the stripe destinations sent in the SPOR command. @par DTP The data transfer process establishes and manages the data connection. The DTP can be passive or active. @par PI The protocol interpreter. The user and server sides of the protocol have distinct roles implemented in a user-PI and a server-PI. @section Existing FTP Standards Used - RFC 959, @ref rfc959 "FILE TRANSFER PROTOCOL (FTP)", J.

Hethmon (September 2000) - Commands used by GridFTP - SIZE - Features used by GridFTP - Restart of a stream mode transfer @anchor sec_SPAS @section SPAS Striped Passive (SPAS) This extension is used to establish a vector of data socket listeners for for a server with one or more stripes. This command MUST be used in conjunction with the extended block mode. The response to this command includes a list of host and port addresses the server is listening on. Due to the nature of the extended block mode protocol, SPAS must be used in conjunction with data transfer commands which receive data (such as STOR, ESTO, or APPE) and can not be used with commands which send data on the data channels. @par Syntax The syntax of the SPAS command is: @code spas = "SPAS" @endcode @par Responses The server-PI will respond to the SPAS command with a 229 reply giving the list of host-port strings for the remote server-DTP or user-DTP to connect to. @code spas-response = "229-Entering Striped Passive Mode" CRLF 1*( host-port CRLF) 229 End @endcode Where the command is correctly parsed, but the server-DTP cannot process the SPAS request, it must return the same error responses as the PASV command. @par OPTS for SPAS There are no options in this SPAS specification, and hence there is no OPTS command defined. @anchor sec_SPOR @section SPOR Striped Data Port (SPOR) This extension is to be used as a complement to the SPAS command to implement striped third-party transfers. This command MUST always be used in conjunction with the extended block mode. The argument to SPOR is a vector of host/TCP listener port pairs to which the server is to connect. This Due to the nature of the extended block mode protocol, SPOR must be used in conjunction with data transfer commands which send data (such as RETR, ERET, LIST, or NLST) and can not be used with commands which receive data on the data channels. @par Syntax The syntax of the SPOR command is: @code SPOR 1*( ) @endcode The host-port sequence in the command structure MUST match the host-port replies to a SPAS command. @par Responses The server-PI will respond to the SPOR command with the same response set as the PORT command described in the @ref rfc959 "ftp specification". @par OPTS for SPOR There are no options in this SPOR specification, and hence there is no OPTS command defined. @anchor sec_ERET @section ERET Extended Retrieve (ERET) The extended retrieve extension is used to request that a retrieve be done with some additional processing on the server. This command an extensible way of providing server-side data reduction or other modifications to the RETR command. This command is used in place of OPTS to the RETR command to allow server side processing to be done with a single round trip (one command sent to the server instead of two) for latency-critical applications. ERET may be used with either the data transports defined in RFC 959, or using extended block mode as defined in this document. Using an ERET creates a new virtual file which will be sent, with it's own size and byte range starting at zero. Restart markers generated while processing an ERET are relative to the beginning of this view of the file. @par Syntax The syntax of the ERET command is @code ERET retrieve-mode ::= P offset ::= 64 bit integer size ::= 64 bit integer @endcode The @b retrieve-mode defines behavior of the extended-retrieve mode. There is one mode defined by this specification, but other general purpose or application-specific ones may be added later. @par modes_ERET Extended Retrieve Modes @par Partial Retrieve Mode (P) A section of the file will be retrieved from the data server. The section is defined by the starting @b offset and extent @b size parameters. When used with extended block mode, the extended block headers sent along with data will send the data with offset of 0 meaning the beginning of the section of the file which was requested.

@anchor sec_ESTO @section ESTO Extended Store (ESTO) The extended store extension is used to request that a store be done with some additional processing on the server. Arbitrary data processing algorithms may be added by defining additional ESTO store-modes. Similar to the ERET, the ESTO command expects data sent to satisfy the request to be sent as if it were a new file with data block offset 0 being beginning the beginning of the new file. The format of the ESTO command is @code ESTO store-mode ::= A @endcode The store-mode defines the behavior of the extended store. There is one mode defined by this specification, but others may be added later. @par Extended Store Modes @par Adjusted store (A) The data in the file is to stored with @b offset added to the file pointer before storing the blocks of the file. In extended block mode, this value is added to the offset in the extended block header by the server when writing to disk. Extended block headers should therefore send the beginning of the byte range on the data channel with offset of zero. In stream mode, the offset is added to the implicit offset of 0 for the beginning of the data before writing. If a stream mode restart marker is used in conjunction with this ESTO mode, the restart marker's offset is added to the offset passed as the parameter to the adjusted store.

@anchor sec_SBUF @section SBUF Set Buffer Size (SBUF) This extension adds the capability of a client to set the TCP buffer size for subsequent data connections to a value. This replaces the server-specific commands SITE RBUFSIZE, SITE RETRBUFSIZE, SITE RBUFSZ, SITE SBUFSIZE, SITE SBUFSZ, and SITE BUFSIZE. Clients may wish to consider supporting these other commands to ensure wider compatibility. @par Syntax The syntax of the SBUF command is @code sbuf = SBUF buffer-size ::= @endcode The @b buffer-size value is the TCP buffer size in bytes. The TCP window size should be set accordingly by the server. @par Response Codes If the server-PI is able to set the buffer size state to the requested buffer-size, then it will return a 200 reply. @note Even if the SBUF is accepted by the server, an error may occur later when the data connections are actually created, depending on how the server or client operating systems' TCP implementations.

@anchor sec_DCAU @section DCAU Data Channel Authentication (DCAU) This extension provides a method for specifying the type of authentication to be performed on FTP data channels. This extension may only be used when the control connection was authenticated using RFC 2228 Security extensions. The format of the DCAU command is @code DCAU authentication-mode ::= | | no-authentication ::= N authenticate-with-self ::= A authenticate-with-subject ::= S subject-name ::= string @endcode @par Authentication Modes - No authentication (N)
No authentication handshake will be done upon data connection establishment. - Self authentication (A)
A security-protocol specific authentication will be used on the data channel. The identity of the remote data connection will be the same as the identity of the user which authenticated to the control connection. - Subject-name authentication (S)
A security-protocol specific authentication will be used on the data channel. The identity of the remote data connection MUST match the supplied @b subject-name string.

The default data channel authentication mode is @b A for FTP sessions which are RFC 2228 authenticated---the client must explicitly send a DCAU N message to disable it if it does not implement data channel authentication. If the security handshake fails, the server should return the error response 432 (Data channel authentication failed). @section mode_e Extended Block Mode The striped and parallel data transfer methods described above require an extended transfer mode to support out-of-sequence data delivery, and partial data transmission per data connection. The extended block mode described here extends the block mode header to provide support for these as well as large blocks, and end-of-data synchronization. Clients indicate that they want to use extended block mode by sending the command @code MODE E @endcode on the control channel before a transfer command is sent. The structure of the extended block header is @code Extended Block Header +----------------+-------/-----------+------/------------+ | Descriptor | Byte Count | Offset Count | | 8 bits | 64 bits | 64 bits | +----------------+-------/-----------+------/------------+ @endcode The descriptor codes are indicated by bit flags in the descriptor byte. Six codes have been assigned, where each code number is the decimal value of the corresponding bit in the byte. @code Code Meaning 128 End of data block is EOR (Legacy) 64 End of data block is EOF 32 Suspected errors in data block 16 Data block is a restart marker 8 End of data block is EOD for a parallel/striped transfer 4 Sender will close the data connection @endcode With this encoding, more than one descriptor coded condition may exist for a particular block. As many bits as necessary may be flagged. Some additional protocol is added to the extended block mode data channels, to properly handle end-of-file detection in the presence of an unknown number of data streams. - When no more data is to be sent on the data channel, then the sender will mark the last block, or send a zero-length block after the last block with the EOD bit (8) set in the extended block header. - After receiving an EOD the data connection can be cached for use in a subsequent transfer. To signifiy that the data connection will be closed the sender sets the close bit (4) in the header on the last message sent. - The sender communicates end of file by sending an EOF message to all servers receiving data. The EOF message format follows. Extended Block EOF Header @code +----------------+-------/--------+------/---------------+ | Descriptor | unused | EOD count expected | | 8 bits | 64 bits | 64 bits | +----------------+-------/--------+------/---------------+ @endcode EOF Descriptor. The EOF header descriptor has the same definition as the regular data message header described above. EOD Count Expected. This 64 bit field represents the total number of data connections that will be established with the server receiving the file. This number is used by the receiver to determine it has received all of the data. When the number of EOD messages received equals the number represented by the "EOD Count Expected" field the receiver has hit end of file. Simply waiting for EOD on all open data connections is not sufficient. It is possible that the receiver reads an EOD message on all of its open data connects while an additional data connection is in flight. If the receiver were to assume it reached end of file it would fail to receive the data on the in flight connection. To handle EOF in the multi-striped server case a 126 response has been introduced. When receiving data from a striped server a client makes a control connection to a single host, but several host may create several data connections back to the client. Each host can independently decide how many data connections it will use, but only a single EOF message may be sent to back to the client, therefore it must be possible to aggregate the total number of data connections used in the transfer across the stripes. The 126 response serves this purpose. The 126 is an intermediate response to RETR command. It has the following format. 126 1*(count of data connections) Several "Count of data connections" can be in a single reply. They correspond to the stripes returned in the response to the SPAS command. Discussion of protocol change to enable bidirectional data channels brought up the following problem if doing bidirectional data channels If the client is pasv, and sending to a multi-stripe server, then the server creates data connections connections; since the client didn't do SPAS, it cannot associate HOST/PORT pairs on the data connections with stripes on the server (it doesn't even know how many there are). it cannot reliably determine which nodes to send data to. (Becomes even more complex in the third-party transfer case, because the sender may have multiple stripes of data.) The basic problem is that we need to know logical stripe numbers to know where to send the data.

@par EOF Handling in Extended Block Mode If you are in either striped or parallel mode, you will get exactly one EOF on each SPAS-specified ports (stripes). Hosts in extended block mode must be prepared to accept an arbitrary number of connections on each SPOR port before the EOF block is sent.

@par Restarting In general, opaque restart markers passed via the block header should not be used in extended block mode. Instead, the destination server should send extended data marker responses over the control connection, in the following form: @code extended-mark-response = "111" "Range Marker" byte-ranges-list = [ *("," ) ] byte-range = "-" start-offset ::= end-offset ::= @endcode

The byte ranges in the marker are an incremental set of byte ranges which have been stored to disk by the data server. The complete restart marker is a concatenation of all byte ranges received by the client in 111 responses. The client MAY combine adjacent ranges received over several range responses into any number of ranges when sending the REST command to the server to restart a transfer. For example, the client, on receiving the responses: @code 111 Range Marker 0-29 111 Range Marker 30-89 @endcode

may send, equivalently, @code REST 0-29,30-89 REST 0-89 REST 30-59,0-29,60-89 @endcode

to restart the transfer after those 90 bytes have been received. The server MAY indicate that a given range of data has been received in multiple subsequent range markers. The client MUST be able to handle this. For example: @code 111 Range Marker 30-59 111 Range Marker 0-89 @endcode

is equivalent to @code 111 Range Marker 30-59 111 Range Marker 0-29,60-89 @endcode

Similarly, the client, if it is doing no processing of the restart markers, MAY send redundant information in a restart. Should these be allowed as restart markers for stream mode?

@par Performance Monitoring In order to monitor the performance of extended block mode transfer, an additional preliminary reply MAY be transmitted over the control channel. This reply is of the form: @code extended-perf-response = "112-Perf Marker" CRLF "Timestamp:" CRLF "Stripe Index:" CRLF "Stripe Bytes Transferred:" CRLF "Total Stripe Count:" CRLF "112 End" CRLF timestamp = [ "." ] @endcode

is seconds since the epoch The performance marker can contain these or any other perf-line facts which provide useful information about the current performance. All perf-line facts represent an instantaneous state of the transfer at the given timestamp. The meaning of the facts are - Timestamp - The time at which the server computed the performance information. This is in seconds since the epoch (00:00:00 UTC, January 1, 1970). - Stripe Index - the index (0-number of stripes on the STOR side of the transfer) which this marker pertains to. - Stripe Bytes Transferred - The number of bytes which have been received on this stripe. A transfer start time can be specified by a perf marker with 'Stripe Bytes Transferred' set to zero. Only the first marker per stripe can be used to specify the start time of that stripe. Any subsequent markers with 'Stripe Bytes Transferred' set to zero simply indicates no data transfer over the interval. A server should send a 'start' marker for each stripe. A server should also send a final perf marker for each stripe. This is a marker with 'Stripe Bytes Transferred' set to the total transfer size for that stripe. @anchor sec_OPTS @section opts Options to RETR The options described in this section provide a means to convey striping and transfer parallelism information to the server-DTP. For the RETR command, the Client-FTP may specify a parallelism and striping mode it wishes the server-DTP to use. These options are only used by the server-DTP if the retrieve operation is done in extended block mode. These options are implemented as @ref rfc2389 "RFC 2389" extensions. The format of the RETR OPTS is specified by: @code retr-opts = "OPTS" "RETR" [ option-list] CRLF option-list = [ layout-opts ";" ] [ parallel-opts ";" ] layout-opts = "StripeLayout=Partitioned" | "StripeLayout=Blocked;BlockSize=" parallel-opts = "Parallelism=" "," "," block-size ::= starting-parallelism ::= minimum-parallelism ::= maximum-parallelism ::= @endcode @par Layout Options The layout option is used by the source data node to send sections of the data file to the appropriate destination stripe. The various StripeLayout parameters are to be implemented as follows: @par Partitioned A partitioned data layout is one where the data is distributed evenly on the destination data nodes. Only one contiguous section of data is stored on each data node. A data node is defined here a single host-port mentioned in the SPOR command @par Blocked A blocked data layout is one where the data is distributed in round-robin fashion over the destination data nodes. The data distribution is ordered by the order of the host-port specifications in the SPOR command. The @b block-size defines the size of blocks to be distributed.

@par PLVL Parallelism Options The parallelism option is used by the source data node to control how many parallel data connections may be established to each destination data node. This extension option provides for both a fixed level of parallelism, and for adapting the parallelism to the host/network connection, within a range. If the @b starting-parallelism option is set, then the server-DTP will make @b starting-parallelism connections to each destination data node. If the @b minimum-parallelism option is set, then the server may reduce the number of parallel connections per destination data node to this value. If the @b maximum-parallelism option is set, then the server may increase the number of parallel connections to per destination data node to at most this value. @section refs References @anchor rfc959 [1] Postel, J. and Reynolds, J., " FILE TRANSFER PROTOCOL (FTP)", STD 9, RFC 959, October 1985. @anchor rfc2389 [2] Hethmon, P. and Elz, R., " Feature negotiation mechanism for the File Transfer Protocol", RFC 2389, August 1998. @anchor rfc2228 [3] Horowitz, M. and Lunt, S., " FTP Security Extensions", RFC 2228, October 1997. @anchor ietfftpext [4] Elz, R. and Hethom, P., " FTP Extensions", IETF Draft, May 2001. @section appendix_i Appendix I: Implementation under GSI

There are several security components in this document which are extensions to the behavior of RFC 2228. These appendix attempts to clarify the protocol how these extensions map to the OpenSSL-based implementation of the GSSAPI known as GSI (Grid Security Infrastructure). A client implementation which communicates with a server which supports the DCAU extension should delegate a limited credential set (using the GSS_C_DELEG_FLAG and GSS_C_GLOBUS_LIMITED_DELEG_PROXY_FLAG flags to gss_init_sec_context()). If delegation is not performed, the client MUST request that DCAU be disable by requesting DCAU N, or the server will be unable to perform the default of DCAU A as described by this document. When DCAU mode "A" or "S" is used, a separate security context is established on each data channel. The context is established by performing the GSSAPI handshake with the active-DTP calling gss_init_sec_context() and the passive-DTP calling gss_accept_sec_context(). No delegation need be done on these data channels. Data channel protection via the PROT command MUST always be used in conjunction with the DCAU A or DCAU S commands. If a PROT level is set, then messages will be wrapped according to RFC 2228 Appendix I using the contexts established on each data channel. Tokens transferred over the data channels when either PROT or DCAU is used are not framed in any way when using GSI. (When implementing this specification with other GSSAPI mechanisms, a 4 byte, big endian, binary token length should procede all tokens). If the DCAU mode or the PROT mode is changed between file transfers when caching data channels in extended block mode, all open data channels must be closed. This is because the GSI implementation does not support changing levels of protection on an existing connection. */ globus_ftp_control-4.7/globus_ftp_control.h0000666000076400007640000016235312100141247016304 00000000000000/* * Copyright 1999-2006 University of Chicago * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ /** * @file globus_ftp_control.h * * GSIFTP Control Connection API (Data structures and types) * */ #ifndef GLOBUS_INCLUDE_FTP_CONTROL_H #define GLOBUS_INCLUDE_FTP_CONTROL_H 1 #ifndef EXTERN_C_BEGIN #ifdef __cplusplus #define EXTERN_C_BEGIN extern "C" { #define EXTERN_C_END } #else #define EXTERN_C_BEGIN #define EXTERN_C_END #endif #endif #include "globus_common.h" #include "globus_error_string.h" #include "globus_io.h" #include "globus_gss_assist.h" #include "globus_handle_table.h" EXTERN_C_BEGIN /** * @mainpage Globus GSIFTP Control Connection API * * The globus_ftp_control library provides low-level services * needed to implement FTP client and servers.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.
