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
|
2019-11-07 23:38:05 +05:30
|
|
|
|
- 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
|
2019-10-13 18:27:05 +05:30
|
|
|
|
- Update COPYING file to GPL 2 rev 2, with new FSF address and other minor stuff
|
|
|
|
|
|
- Update license header in all files:
|
2019-11-07 23:38:05 +05:30
|
|
|
|
- Sync 3-clause BSD license change with upstream NetBSD and FreeBSD sources
|
2019-10-13 18:27:05 +05:30
|
|
|
|
- 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()`"
|
2019-11-07 23:38:05 +05:30
|
|
|
|
- Major code cleanup and rewrite inspired by both NetBSD and FreeBSD
|
|
|
|
|
|
sources, e.g. removed all previous unit `TESTING` #ifdefs

|
|
|
|
|
|
again after a filled up disk
|
|
|
|
|
|
- Removed test to detect control characters > 0x20 as this prevented

|
|
- 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.

- klogd will set the console log level only if `-c' is given on the

. Removed kernel.patch since it is no longer required
. Changed SOCK_STREAM to SOCK_DGRAM in syslog.c
. klogd will only change the console log level if `-c' is supplied
. syslogd.c by Bill Nottingham <notting@redhat.com>
Um, if the directory is invalid, the bind() call in
create_unix_socket fails. Without the return -1, we return the
invalid fd that we just closed. When syslogd then starts
listening, select goes into a hard loop getting EBADF, IIRC.
. klogd.c by Troels Walsted Hansen <troels@thule.no>
I found a bug in the sysklogd package version 1.4. When it
encounters a zero byte in the kernel logging output, the text
parser enters a busy loop. I came upon it when the 3c59x driver
from kernel 2.4.0 started outputting two zero bytes for the product
code of my laptop's 3Com card. It could be argued that the kernel
should never output zero bytes in the logging info, but obviously
that will happen from time to time.
I fear this bug might be considered a security issue as well, if
the kernel can be coerced to output a zero byte somehow, all kernel
logging will stop.
Wolfgang Oertl <Wolfgang.Oertl@uibk.ac.at> had a similar bugfix
idea
. klogd.c by Thomas Roessler <roessler@does-not-exist.org>
Additionally, the patch prevents LogLine from being invoked with a
negative counter as an argument.

- 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.

|
* New upstream source (closes: Bug#87819, Bug#70790, Bug#32580,
Bug#62358, Bug#71631)
* Upstream: Doesn't re-set log-level if not requested (closes:
Bug#76170, Bug#76170, Bug#85289)
* Upstream: Ignore zero bytes (closes: Bug#85478, Bug#85478, Bug#41068)
* Upstream: Corrected documentation for `-s' (closes: Bug#87020)
* Upstream: test for existence of syslogd-listfiles before calling
them. This got lost due to 1.4.0 brokennes which was packaged and
removed some hours later (closes: Bug#84872, Bug#66712)
* Applied patch by Tommi Virtanen <tv@debian.org> splitting the package
into `sysklogd' and `klogd' (closes:Bug#35586, Bug#72043, Bug#74864,
Bug#72122)
* Provide / depend on virtual packages system-log-daemon
and linux-kernel-log-daemon (closes: Bug#67604)
* Applied patch from Tim Janik <timj@gtk.org> to support `-s pattern' in
syslogd-listfiles
* Transition to FHS, i.e. /usr/share/doc instead of /usr/doc and
/usr/share/man instead of /usr/man (closes: Bug#79250, Bug#80771)
* Use --exec for stopping services (closes: Bug#76757)
* Corrected broken character in klogd.8 (cloes: Bug#75932)
* Only rotate logfiles with size greater than zero. This got lost due
to 1.4.0 brokennes which was packaged and removed some hours later
(closes: Bug#74993, Bug#49824)
* Added another note about modificability of cronjobs (closes:
Bug#88741)
* Since klogd replaces parts of sysklogd a proper Replaces line is there
* Added final newline to CHANGES
