All relevant changes to the project are documented in this file.
|
||
|
||
|
||
[v2.1.1][] - 2020-01-19
|
||
-----------------------
|
||
|
||
Bug fix release.
|
||
|
||
### Changes
|
||
- Add unit test to verify rule option parsing
|
||
- Minor code cleanup and code de-duplication
|
||
|
||
### Fixes
|
||
- Issue #11: Some users still reported problems with parallel build,
|
||
which was worked-around with `.NOTPARALLEL` in [v2.1][]. This v2 fix
|
||
is a refactor of `src/Makefile.am` which removes `libcompat` and use
|
||
the same objects for linking both `syslogd` and the user `libsyslog`
|
||
API. Yet still protecting against symbol poisoning
|
||
- A Westermo customer reported problems sending to remove syslog sinks
|
||
at startup. Turns out the handling if `sendmsg()` fails was the same
|
||
as that if `syslogd` fails to resolve the IP from a DNS name. The fix
|
||
is to just let `sendmsg()` retry on the next syslog message for all
|
||
benign/common network errors; `EHOSTUNREACHABLE`, `ENETUNREACH`, etc.
|
||
- Fix timer reset for suspended remote sinks. For all new incoming syslog
|
||
messages all suspended (remote) sinks had their timeout mistakenly reset
|
||
|
||
|
||
[v2.1][] - 2020-01-05
|
||
---------------------
|
||
|
||
Relicensed under the 3-clause BSD license.
|
||
|
||
### Changes
|
||
- `klogd` removed, replaced by native `syslogd` functionality
|
||
- Import pristine FreeBSD versions of `syslogd` and `syslog.conf` man
|
||
pages, both under the 3-clause BSD license.
|
||
- With `klogd` removed and the original man pages replaced with FreeBSD
|
||
versions, the only remaining GPL'ed material was the build system,
|
||
which the copyright owner (undersigned) agrees to change to BSD as
|
||
well. Hence, the GNU GPL could be dropped in favor of 3-clause BSD
|
||
|
||
### Fixes
|
||
- Issue #8: Kernel messages duplicated to console. `syslogd` on Linux
|
||
now calls `klogctl()` to disable kernel logging to console
|
||
- Earlier versions were slightly sensitive to time skips. I.e., when
|
||
recording the last-change time on a log file and wall time changed
|
||
backwards, `syslogd` would consider that log file to have a date in
|
||
the future. This only affected buffering of multiple messages, and
|
||
`-- MARK --` so most users never would have noticed
|
||
- Issue #9: Kernel logging broken if `syslogd` started without `-F`
|
||
- Issue #10: Fix build on non-GLIBC Linux systems, by Khem Raj
|
||
- Issue #11: Fix nasty parallel build problem. Also reported by the
|
||
Gentoo project, and Westermo
|
||
- Make sure log rotation cannot be enabled for non-file targets
|
||
- Use `snprintf()` rather than `sprintf()` in log rotation
|
||
- Fix variable names shadowing global/local defs, found by clang-tidy
|
||
- Handle multiple invocations of SIGHUP, respond to all of them
|
||
- Use correct `#ifdef` for checking on Linux or not
|
||
|
||
|
||
[v2.0.3][] - 2019-12-01
|
||
-----------------------
|
||
|
||
### Changes
|
||
- Always run `domark()` timer, regardless of `-m interval` setting,
|
||
it is used for internal housekeeping, runs every 15 sec
|
||
- Handle DNS lookup of unknown remote syslog hosts in `domark()`
|
||
- Only enable debug mode when `-d` is given on the command line
|
||
- Always create PID file, even in debug mode
|
||
- Add `-F`, as alias for `-n`, to klogd for compat. with syslogd
|
||
|
||
### Fixes
|
||
- When logging to a remote host using @FQDN previous releases of syslogd
|
||
gave up after 10 tries. In many industrial cases intermittent access
|
||
to the DNS is very likely, so this release includes a fix to retry the
|
||
IP address lookup forever. The interval for retries is configurable
|
||
- Fix accidental blocking of SIGHUP/SIGALRM when an invalid facility is
|
||
found in the internal `logmsg()` function
|
||
- Fix leaking of internal error messages (like DNS lookup failure) to
|
||
`/dev/console` during reconfiguration, i.e. after initial start
|
||
|
||
|
||
[v2.0.2][] - 2019-11-28
|
||
-----------------------
|
||
|
||
### Changes
|
||
- Add missing remote:port info in error message when failing to send to
|
||
a remote syslog server.
|
||
|
||
### Fixes
|
||
- Fix `assert()` in `fprintlog_successive()`, caused by never being
|
||
reset in `fprintlog_first()`, found by Westermo
|
||
- Issue #6: Workaround for systems with vanilla autoconf 2.69 that does
|
||
not support `--runstatedir=PATH`, e.g. CRUX <https://crux.nu/>
|
||
|
||
|
||
[v2.0.1][] - 2019-11-25
|
||
-----------------------
|
||
|
||
Minor bug fix release.
|
||
|
||
### Changes
|
||
- Make logger tool and man page optional in build, by Lars Wendler
|
||
- Expand resulting directories in configure summary
|
||
|
||
### Fixes
|
||
- Add missing `-k` and `-T` command line flags to `getopt()`
|
||
- Issue #3: Don't guess PID file location, use configre's `$runstatedir`
|
||
|
||
|
||
[v2.0][] - 2019-11-15
|
||
---------------------
|
||
|
||
This release represents a major refresh of the sysklogd project. The
|
||
venerable syslogd gets an infusion of new blood from NetBSD and FreeBSD
|
||
to fully support RFC3164 and RFC5424. Also included is a user library
|
||
and a replacement for `syslog.h` to enable new features in RFC5424.
|
||
|
||
> Note: as of this release `klogd` is disabled by default, `syslogd` can
|
||
> read Linux kernel messages on its own now.
|
||
|
||
### Changes
|
||
- Support for true RFC3164 formatted log messages to remote log servers,
|
||
including timestamp and hostname. Use `;RFC3161` rule option
|
||
- Support for RFC5424 from UNIX domain socket, from remote servers and also
|
||
to remote servers. Requires new API `syslogp()` to unlock these features
|
||
on the UNIX socket. Still compatible with GLIBC/musl/uClibc
|
||
- Support for options to `syslog.conf` rules. E.g. `;RFC5424` to enable
|
||
sending/writing log messages with RFC3339 style timestamps, and more
|
||
- Support for `include /etc/syslog.d/*.conf` in `syslog.conf`
|
||
- New tool `logger` from the Finit project, BSD licensed. Supports all the
|
||
features of RFC5424, so *very* useful for trying out the "new" standard
|
||
- Support for reading from a custom UNIX domain socket path, `-p SOCK`,
|
||
for unit testing with `logger -u /path/to/sock`
|
||
- Support for sending to a custom port on a remote server, `@host:port`
|
||
- New `syslogp()` API from NetBSD, for applications wanting to use
|
||
RFC5424 features like MsgID or structured data
|
||
- Many *incompatible changes* to command line options in `syslogd` and
|
||
`klogd` for compatiblity with FreeBSD and NetBSD syslogd. Examples:
|
||
- In syslogd: `-b` and `-c` have been replaced with `-r` for global
|
||
log rotation, `-a` has been replaced with the new `-p` support. The
|
||
`-r` flag and `-s HOST` has also been dropped in favor of the BSD
|
||
`-s` flag to control two levels of _secure mode_. The `-n` flag is
|
||
now `-F` and `-n` means something else entirely ... there's more
|
||
- In klogd: `-i` and `-I` have been removed
|
||
- `klogd` is not built by default anymore, `syslogd` can read `/proc/kmsg`
|
||
on Linux on its own. Reduces complexity and gives you one daemon less
|
||
- When systemd support is detected by the configure script the unit file(s)
|
||
are now installed into the systemd system services folder
|
||
- Update COPYING file to GPL 2 rev 2, with new FSF address and other minor stuff
|
||
- Update license header in all files:
|
||
- Sync 3-clause BSD license change with upstream NetBSD and FreeBSD sources
|
||
- Sync GPL license header, new FSF address
|
||
- Add SPDX license identifiers to all source files
|
||
|
||
### Fixes
|
||
- Fix GCC 8 warnings; "too small destination buffer in `snprintf()`"
|
||
- Major code cleanup and rewrite inspired by both NetBSD and FreeBSD
|
||
sources, e.g. removed all previous unit `TESTING` #ifdefs
|
||
|
||
|
||
[v1.6][] - 2018-09-25

|
||
- Steve Grubb <linux_4ever@yahoo.com>
|
||
- fix memory calculation in crunch_list()

||
network activity
|
||
- Continue writing to log files as soon as space becomes available

[v1.4.1][] - 2001-03-11
|
||
-----------------------
|
||
|
||
- klogd will set the console log level only if `-c' is given on the
|
||
commandline, not overwriting local settings in `/etc/sysctl.conf'.
|
||
- Bugfix: klogd will use SOCK_DGRM as well, re-enables kernel logging

||
- Fixed bug that caused klogd to die if there is no sym_array available.
|
||
- When symbols are expanded, print the line twice. Once with
|
||
addresses converted to symbols, once with the raw text. Allows
|
||
external programs such as ksymoops do their own processing on the
|
||
original data.
|
||
- Olaf Kirch <okir@caldera.de>
|
||
- Remove Unix Domain Sockets and switch to Datagram Unix Sockets
