Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

The elements * are singly linked for minimum space and pointer manipulation overhead at * the expense of O(n) removal for arbitrary elements. New elements can be * added to the list after an existing element or at the head of the list. * Elements being removed from the head of the list should use the explicit * macro for this purpose for optimum efficiency. A singly-linked list may * only be traversed in the forward direction. Singly-linked lists are ideal * for applications with large datasets and few or no removals or for * implementing a LIFO queue. * * A list is headed by a single forward pointer (or an array of forward * pointers for a hash table header). The elements are doubly linked * so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before * or after an existing element or at the head of the list. A list * may only be traversed in the forward direction. * * A simple queue is headed by a pair of pointers, one the head of the * list and the other to the tail of the list. The elements are singly * linked to save space, so elements can only be removed from the * head of the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the * list. A simple queue may only be traversed in the forward direction. * * A tail queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or * after an existing element, at the head of the list, or at the end of * the list. A tail queue may be traversed in either direction. * * A circle queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the list. * A circle queue may be traversed in either direction, but has a more * complex end of list detection. * * For details on the use of these macros, see the queue(3) manual page. */ #if defined(QUEUE_MACRO_DEBUG) || (defined(_KERNEL) && defined(DIAGNOSTIC)) #define _Q_INVALIDATE(a) (a) = ((void *)-1) #else #define _Q_INVALIDATE(a) #endif /* * Singly-linked List definitions. */ #define SLIST_HEAD(name, type) \ struct name { \ struct type *slh_first;

It'll see the old AC_DEFUN # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us # using a macro with the same name in our local m4/libtool.m4 it'll # pull the old libtool.m4 in (it doesn't see our shiny new m4_define # and doesn't know about Autoconf macros at all.) # # So we provide this file, which has a silly filename so it's always # included after everything else.

It has seen improvements from many others as well. Please see the commit logs for an exhaustive list of contributors. Portable OpenNTPD versions 3.9 and earlier were developed by Darren Tucker, with contributions from Christian Weisgerber, Jason Mader and Anthony O.Zabelin., and were based heavily on OpenSSH portable. It also has seen improvements from many others. Refer to the commit logs for an exhaustive list. This new portable version is based on the LibreSSL portable framework by Brent Cook. It includes patches from FreeBSD, Debian and Gentoo OpenNTPD packages, along with with compatibility code from the portable OpenSSH and original portable OpenNTPD trees. openntpd-6.2p3/VERSION0000644000175000017500000000000613176213013011435 000000000000006.2p3 openntpd-6.2p3/README0000644000175000017500000000250313176213013011251 00000000000000This is a new port of OpenBSD's native ntpd to other Unix flavours adding autoconf support and the necessary compatibility layer. It is based on portability code from the OpenSSH and LibreSSL portable projects. OpenNTPD has a web site at http://www.openntpd.org/ The current portable tree can be found at https://github.com/openntpd-portable Platform Requirements --------------------- - adjtime(2) and settimeofday(2) syscalls or equivalent. - adjfreq(2) or an equivalent compatibility function for best results - daemon(3), setresgid(2), setresuid(2) or equivalent - A working arc4random(2) implementation, OpenSSL or LibreSSL (this project shares the same arc4random compatibility code from LibreSSL) - libtls (included with LibreSSL 2.1.4 or higher) is required for HTTPS time constraint validation. At the time of writing the Portable version is known to build and work on: - OpenBSD (5.6) - Linux (Ubuntu 12.04, 14.04) - FreeBSD (9.x, 10.x) - NetBSD (6.1.5) - Solaris (10.x, 11.x) - Mac OS X (10.9) OpenNTPD may work on other operating systems, newer and older, but the above ones are tested regularly by the developer. Reports (success or otherwise) are welcome.

Thanks to Luis M. Merino. 2016-03-29 OpenNTPD 5.9p1 * When a single "constraint" is specified, try all returned addresses until one succeeds, rather than the first returned address. * Relaxed the constraint error margin to be proportional to the number of NTP peers, avoid constant reconnections when there is a bad NTP peer. * Removed disabled hotplug sensor support. * Added support for detecting crashes in constraint subprocesses. * Moved the execution of constraints from the ntp process to the parent process, allowing for better privilege separation since the ntp process can be further restricted. * Added pledge(2) support. * Updated to require LibreSSL 2.3.2 or greater. * Fixed high CPU usage when the network is down. * Fixed various memory leaks. * Switched to RMS for jitter calculations. * Unified logging functions with other OpenBSD base programs. OpenNTPD portable-specific changes: * Added support for syncing time with the Realtime Clock (RTC) on OSes that require it. * CFLAGS is no longer overridden by the build system. * FreeBSD RTABLE support is disabled * FreeBSD is no longer linked with -lmd to avoid hash function collisions, causing failures in constraint certificate loading. * Fixed crashes due to __progname being used before initialized. * Added Solaris 10 compatibility. * Added --disable-https-constraint build option for explicitly disabling constraint support. * Synced build system files with LibreSSL The libtls library, as shipped with LibreSSL 2.3.2 or later, is required to use the HTTPS constraint feature, though it is not required to use OpenNTPD. 2015-03-24 OpenNTPD 5.7p4 * Added support for HTTPS constraints to validate NTP responses. See the man page and example config file for how to configure it. The initial announcement: http://marc.info/?l=openbsd-tech&m=142356166731390&w=2 is an explanation of the rationale and how the feature works. * Workaround an apparent bug in Solaris adjtime that cause the clock to report sync/unsync continuously. * Workaround an issue on systems with 32-bit time_t that causes an overflow if the system time is later than early 2036. The libtls library, as shipped with LibreSSL 2.1.4 or later, is required to use the HTTPS constraint feature, though it is not required to use OpenNTPD. 2015-01-27 OpenNTPD 5.7p3 * Fixed issue resolving hostnames when the network is initially unavailable. * Fixed process name logging on Linux and OS X. * Fixed adjfreq failures on Solaris due to uninitialized struct timex. * Support building on Linux musl libc. * Default privilege separation directory changed from /var/empty/ntp to /var/empty. Please ensure that if you are using the default from previous releases that the privsep directory is empty, owned by root, and has no write privileges for other users. 2015-01-20 OpenNTPD 5.7p2 * Switched the drift file from an unscaled frequency offset to ppm. The latter format is compatible with that of ntp.org. This allows easy switching between ntpd daemons * Fixed a memory leak in DNS lookups. * Added support for setting the process title on Linux and OS X. The different processes are now possible to tell apart by role in the process list. * Import NetBSD support. * Various bugfixes and refinements from the community. 2015-01-08 OpenNTPD 5.7p1 * Support for a new build infrastructure based on the LibreSSL framework. Source code is integrated directly from the OpenBSD tree with few manual changes, easing maintenance. * Removed support for several OSes pending test reports and updated portability code. * Supports the Simple Network Time Protocol version 4 as described in RFC 5905 * Added route virtualization (rdomain) support. * Added ntpctl(8), which allows for querying ntpd(8) at runtime. * Finer-grained clock adjustment via adjfreq / ntp_adjtime where available. * Improved latency on heavily-loaded machines. openntpd-6.2p3/src/0000755000175000017500000000000013176213170011244 500000000000000openntpd-6.2p3/src/ntpd.conf.50000644000175000017500000001551613176213141013151 00000000000000.\" $OpenBSD: ntpd.conf.5,v 1.37 2017/08/10 22:59:42 job Exp $ .\" .\" Copyright (c) 2003, 2004 Henning Brauer .\" .\" Permission to use, copy, modify, and distribute this software for any .\" purpose with or without fee is hereby granted, provided that the above .\" copyright notice and this permission notice appear in all copies. .\" .\" THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES .\" WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF .\" MERCHANTABILITY AND FITNESS.

The basic configuration options are as follows: .Bl -tag -width Ds .It Xo Ic listen on Ar address .Op Ic rtable Ar table-id .Xc .Xr ntpd 8 has the ability to sync the local clock to remote NTP servers and, if this directive is specified, can act as NTP server itself, redistributing the local clock. .Pp Specify a local IP address or a hostname the .Xr ntpd 8 daemon should listen on to enable remote clients synchronization. If it appears multiple times, .Xr ntpd 8 will listen on each given address. If .Sq * is given as an address, .Xr ntpd 8 will listen on all local addresses using the specified routing table. .Xr ntpd 8 does not listen on any address by default. The optional .Ic rtable keyword will specify which routing table to listen on, if the operating system supports rdomains. By default .Xr ntpd 8 will listen using the current routing table. For example: .Bd -literal -offset indent listen on * .Ed .Pp or .Bd -literal -offset indent listen on 127.0.0.1 listen on ::1 listen on 127.0.0.1 rtable 4 .Ed .It Ic query from Ar address Specify a local IP address the .Xr ntpd 8 daemon should use for outgoing queries to subsequently specified servers. For example: .Bd -literal -offset indent query from 192.0.2.1 query from 2001:db8::1 .Ed .It Xo Ic sensor Ar device .Op Ic correction Ar microseconds .Op Ic weight Ar weight-value .Op Ic refid Ar string .Op Ic stratum Ar stratum-value .Xc Specify a timedelta sensor device .Xr ntpd 8 should use, if the operating system supports sensors. The sensor can be specified multiple times: .Xr ntpd 8 will use each given sensor that actually exists. Non-existent sensors are ignored. If .Sq * is given as device name, .Xr ntpd 8 will use all timedelta sensors it finds. .Xr ntpd 8 does not use any timedelta sensor by default. For example: .Bd -literal -offset indent sensor * sensor nmea0 .Ed .Pp An optional correction in microseconds can be given to compensate for the sensor's offset. The maximum correction is 127 seconds. For example, if a DCF77 receiver is lagging 70ms behind actual time: .Bd -literal -offset indent sensor udcf0 correction 70000 .Ed .Pp The optional .Ic weight keyword permits finer control over the relative importance of time sources (servers or sensor devices). Weights are specified in the range 1 to 10; if no weight is given, the default is 1. A server with a weight of 5, for example, will have five times more influence on time offset calculation than a server with a weight of 1. .Pp An optional reference ID string - up to 4 ASCII characters - can be given to publish the sensor type to clients. RFC 2030 suggests some common reference identifiers, but new identifiers "can be contrived as appropriate." If an ID string is not given, .Xr ntpd 8 will use a generic reference ID. For example: .Bd -literal -offset indent sensor nmea0 refid GPS .Ed .Pp A stratum value other than the default of 1 can be assigned using the .Ic stratum keyword. .It Xo Ic server Ar address .Op Ic weight Ar weight-value .Xc Specify the IP address or the hostname of an NTP server to synchronize to. If it appears multiple times, .Xr ntpd 8 will try to synchronize to all of the servers specified. If a hostname resolves to multiple IPv4 and/or IPv6 addresses, .Xr ntpd 8 uses the first address. If it does not get a reply, .Xr ntpd 8 retries with the next address and continues to do so until a working address is found. For example: .Bd -literal -offset indent server 10.0.0.2 weight 5 server ntp.example.org weight 1 .Ed .Pp To provide redundancy, it is good practice to configure multiple servers. In general, best accuracy is obtained by using servers that have a low network latency. .It Xo Ic servers Ar address .Op Ic weight Ar weight-value .Xc As with .Cm server , specify the IP address or hostname of an NTP server to synchronize to. If it appears multiple times, .Xr ntpd 8 will try to synchronize to all of the servers specified. Should the hostname resolve to multiple IP addresses, .Xr ntpd 8 will try to synchronize to all of them. For example: .Bd -literal -offset indent servers pool.ntp.org servers pool.ntp.org weight 5 .Ed .El .Sh CONSTRAINTS .Xr ntpd 8 can be configured to query the .Sq Date from trusted HTTPS servers via TLS. This time information is not used for precision but acts as an authenticated constraint, thereby reducing the impact of unauthenticated NTP man-in-the-middle attacks. Received NTP packets with time information falling outside of a range near the constraint will be discarded and such NTP servers will be marked as invalid. .Pp Support for constraints is only available if .Xr ntpd 8 has been linked with libtls from LibreSSL. Configuring a constraint without libtls causes .Xr ntpd 8 to log a warning message on startup. .Bl -tag -width Ds .It Ic constraint from Ar url Specify the URL, IP address or the hostname of an HTTPS server to provide a constraint. If .Ic constraint from is used more than once, .Xr ntpd 8 will calculate a median constraint from all the servers specified. .Bd -literal -offset indent server ntp.example.org constraint from www.example.com .Ed .It Ic constraints from Ar url As with .Ic constraint from , specify the URL, IP address or the hostname of an HTTPS server to provide a constraint. Should the hostname resolve to multiple IP addresses, .Xr ntpd 8 will calculate a median constraint from all of them. For example: .Bd -literal -offset indent servers pool.ntp.org constraints from "https://www.google.com/" .Ed .El .Sh FILES .Bl -tag -width "/etc/ntpd.confXXX" -compact .It Pa /etc/ntpd.conf default .Xr ntpd 8 configuration file .El .Sh SEE ALSO .Xr ntpctl 8 , .Xr ntpd 8 , .Xr sysctl 8 .Sh HISTORY The .Nm file format first appeared in .Ox 3.6 . openntpd-6.2p3/src/client.c0000644000175000017500000003166613176213141012620 00000000000000/* $OpenBSD: client.c,v 1.105 2017/05/30 23:30:48 benno Exp $ */ /* * Copyright (c) 2003, 2004 Henning Brauer * Copyright (c) 2004 Alexander Guy * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

It implements the Simple Network Time Protocol version 4, as described in RFC 5905, and the Network Time Protocol version 3, as described in RFC 1305. Time can also be fetched from TLS HTTPS servers to reduce the impact of unauthenticated NTP man-in-the-middle attacks. .Pp The options are as follows: .Bl -tag -width "-f fileXXX" .It Fl d Do not daemonize. If this option is specified, .Nm will run in the foreground and log to .Em stderr . .It Fl f Ar file Use .Ar file as the configuration file, instead of the default .Pa /etc/ntpd.conf . .It Fl n Configtest mode. Only check the configuration file for validity. .It Fl p Ar file Write pid to .Ar file .It Fl S Do not set the time immediately at startup. This is the default. .It Fl s Try to set the time immediately at startup, as opposed to slowly adjusting the clock. .Nm will stay in the foreground for up to 15 seconds waiting for one of the configured NTP servers to reply. .It Fl v This option allows .Nm to send DEBUG priority messages to syslog. .El .Pp .Nm uses the .Xr adjtime 2 system call to correct the local system time without causing time jumps. Adjustments of 32ms and greater are logged using .Xr syslog 3 . The threshold value is chosen to avoid having local clock drift thrash the log files. Should .Nm be started with the .Fl d or .Fl v option, all calls to .Xr adjtime 2 will be logged. .Pp After the local clock is synchronized, .Nm adjusts the clock frequency using the .Xr adjfreq 2 system call to compensate for systematic drift. .Pp .Nm is started at boot time by default via .Va ntpd_flags in .Pa /etc/rc.conf . See .Xr rc 8 and .Xr rc.conf 8 for more information on the boot process and enabling daemons. .Pp When .Nm starts up, it reads settings from its configuration file, typically .Xr ntpd.conf 5 , and its initial clock drift from .Pa /var/db/ntpd.drift . Clock drift is periodically written to the drift file thereafter. .Sh FILES .Bl -tag -width "/var/db/ntpd.driftXXX" -compact .It Pa /etc/ntpd.conf Default configuration file. .It Pa /var/db/ntpd.drift Drift file. .It Pa /var/run/ntpd.sock Socket file for communication with .Xr ntpctl 8 . .El .Sh SEE ALSO .Xr date 1 , .Xr adjfreq 2 , .Xr adjtime 2 , .Xr ntpd.conf 5 , .Xr ntpctl 8 , .Xr rc 8 , .Xr rc.conf 8 , .Xr rdate 8 .Sh STANDARDS .Rs .%A David L.

Keywords may be abbreviated. .Pp .Cm all shows all data available. .Pp .Cm peers shows the following information about each peer: weight, trustlevel, stratum, number of seconds until the next poll, polling interval in seconds, and offset, network delay and network jitter in milliseconds. When the system clock is synced to a peer, an asterisk is displayed to the left of the weight column for that peer. .Pp .Cm Sensors shows the following information about each sensor: weight, sensor "good" status, stratum, and offset and the configured correction in milliseconds. When the system clock is synced to a sensor, an asterisk is displayed to the left of the weight column for that sensor. .Pp .Cm status shows the status of peers and sensors, and whether the system clock is synced. When the system clock is synced, the stratum is displayed. When the system clock is not synced, the offset of the system clock, as reported by the .Xr adjtime 2 system call, is displayed. When the median constraint is set, the offset to the local time is displayed. .El .Sh FILES .Bl -tag -width "/var/run/ntpd.sockXXX" -compact .It Pa /var/run/ntpd.sock Socket file for communication with .Xr ntpd 8 . .El .Sh SEE ALSO .Xr adjtime 2 , .Xr ntpd.conf 5 , .Xr ntpd 8 .Sh HISTORY The .Nm program first appeared in .Ox 5.5 . openntpd-6.2p3/src/server.c0000644000175000017500000001357513176213141012647 00000000000000/* $OpenBSD: server.c,v 1.44 2016/09/03 11:52:06 reyk Exp $ */ /* * Copyright (c) 2003, 2004 Henning Brauer * Copyright (c) 2004 Alexander Guy * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

Prerequisites ---------------- You will need an entropy (randomness) source. If your OS has arc4random or getentropy then that is ideal. Otherwise, you can use the builtin arc4random implementation or the one built into LibreSSL. 2. Building / Installation -------------------------- If you have checked this source using Git, follow these initial steps to prepare the source tree for building: 1. ensure you have the following packages installed: automake, autoconf, git, libtool, bison 2. run './autogen.sh' to prepare the source tree for building or run './dist.sh' to prepare a tarball. To install OpenNTPD with default options: ./configure make make install This will install the OpenNTPD binary in /usr/local/sbin, configuration files in /usr/local/etc. To specify a different installation prefix, use the --prefix option to configure: ./configure --prefix=/opt make make install Will install OpenNTPD in /opt/{etc,sbin}. You can also override specific paths, for example: ./configure --prefix=/opt --sysconfdir=/etc/ntp make make install This will install the binaries in /opt/sbin, but will place the configuration files in /etc/ntp. OpenNTPD always uses Privilege Separation (ie the majority of the processing is done as a chroot'ed, unprivileged user). This requires that a user, group and directory to be created for it. The user should not be permitted to log in, and its home directory should be owned by root and be mode 755. If you do "make install", the Makefile will create the directory with the correct permissions and will prompt you for the rest if required. If, however, you need to perform all of these tasks yourself (eg if you are moving the built binaries to another system) then you will need to do something like the following (although the exact commands required for creating the user and group are system dependant): On most Linux and BSD systems, something like should work: groupadd _ntp useradd -g _ntp -s /sbin/nologin -d /var/empty -c 'OpenNTP daemon' _ntp mkdir -p /var/empty chown 0 /var/empty chgrp 0 /var/empty chmod 0755 /var/empty /var/empty here is a chroot directory used by ntpd for privilege separation of the DNS and NTP processes. This directory should not contain any files, must be owned by root, and must not be group or world-writable. NOTE: If you installed a previous OpenNTPD release and created a /var/empty/ntp directory, please delete the /var/empty/ntp directory and adjust the _ntp user's home directory to point to /var/empty instead. This is important because, if you have any other daemons that also use /var/empty as a home directory, they will all have an empty privilege separation directory. As of OS X 10.10, something like this should work similarly (thanks to jasper@ for suggesting) dscl . create /Users/_ntp dscl . create /Users/_ntp UserShell /sbin/nologin # Prevent user from showing up on the login screen dscl . delete /Users/_ntp AuthenticationAuthority # Arbitrarily chosen UID that was free dscl . create /Users/_ntp UniqueID 400 dscl . create /Users/_ntp PrimaryGroupID 400 dscl . create /Users/_ntp RealName "OpenNTPD user" dseditgroup -o create _ntp dscl . append /Groups/_ntp GroupMembership _ntp There are a few options to the configure script in addition to the ones provided by autoconf itself: --with-privsep-user=[user] Specify unprivileged user used for privilege separation. The default is "_ntp". --with-privsep-path=path ntpd will always use the home directory of the privsep user to chroot to, but specifying this parameter will change the post-installation checks and instructions to match the specified path. --with-cacert=[path] Specify the CA certificate location for HTTPS constraint validation. Defaults to /etc/ssl/certs/ca-certificates.crt If you need to pass special options to the compiler or linker, you can specify these as environment variables before running ./configure. For example: CFLAGS="-O2 " LDFLAGS="-s" ./configure 3. Configuration ---------------- The runtime configuration files are installed by in ${prefix}/etc or whatever you specified as your --sysconfdir (/usr/local/etc by default). If no configuration file exists, the default one is used. The default configuration file uses a selection of publicly accessible "pool" servers (see http://support.ntp.org/bin/view/Servers/NTPPoolServers) 4.
