[v2.0][UNRELEASED]
------------------
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.
### 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 the
new features. 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`
- 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 tool `logger` from the Finit project, BSD licensed
- New `syslogp()` API from NetBSD, for applications wanting to use
RFC5424 features like MsgID or structured data
- Incompatible changes to command line options for `syslogd` and
`klogd`, e.g;
- In syslogd: `-b` and `-c` have been replaced with `-R` for global
log rotation, `-a` has been replaced with the new `-p` support
- In klogd: `-i` and `-I` have been removed
- 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

---------------------
- Dmitry V. Levin <ldv@altlinux.org>
2005-01-16 00:44:21 +05:30
- Close file descriptor in FindSymbolFile() in ksym.c in order not to
leak file descriptors.
- Solar Designer <solar@openwall.com>
2005-01-16 00:44:21 +05:30
- improve crunch_list()
- Prevent potential buffer overflow in reading messages from the
kernel log ringbuffer.
- Ensure that "len" is not placed in a register, and that the
endtty() signal handler is not installed too early which could
cause a segmentation fault or worse.
- Steve Grubb <linux_4ever@yahoo.com>
2005-01-16 00:44:21 +05:30
- fix memory calculation in crunch_list()
- Martin Schulze <joey@infodrom.org>
2005-01-16 00:44:21 +05:30
- klogd will reconnect to the logger (mostly syslogd) after it went
away
- On heavily loaded system syslog will not spit out error messages
anymore when recvfrom() results in EAGAIN
- Makefile improvements
- Local copy of module.h
- Improved sysklogd.8
- Always log with syslogd's timezone and locale
- Remove trailing newline when forwarding messages
2007-06-21 13:52:59 +05:30
- Continue working properly if /etc/service is missing and ignore
network activity
- Continue writing to log files as soon as space becomes available
again after a filled up disk
- Removed test to detect control characters > 0x20 as this prevented
characters encoded in UTF-8 to be properly passed through
- Only resolve the local domain when accepting messages from remote
- Properly accompany the MARK message with the facility
- Improved daemonise routine in klogd to stabilise startup
- klogd will not change the console log level anymore unless -c is given
- Added back /usr/src/linux/System.map as fall-back location
- Rewrote the module symbol parser to read from /proc/kallsyms
2007-07-29 23:07:07 +05:30

- Improved symbol lookup
- Prevent named pipes from becoming the controlling tty
- Jon Burgess <Jon_Burgess@eur.3com.com>
- Moved the installation of the signal handler up a little bit so it
guaranteed to be available when the child is forked, hence, fixing a
race condition. This used to create problems with UML and fast
machines.

---------------------
- Skip newline when reading in klog messages
- Use lseek64() instead of llseek() which is deprecated these days
- Close symbol file before returning with 0 when an error occurred

- priority decoding fix
- Daniel Jacobowitz <dan@debian.org>
- printchopped() fix
- Keith Owens <kaos@ocs.com.au>

addresses converted to symbols, once with the raw text. Allows
external programs such as ksymoops do their own processing on the
original data.

- Remove Unix Domain Sockets and switch to Datagram Unix Sockets
- Several bugfixes and improvements, please refer to the .c files
