On behalf of the beta-testers and other members of the Linux INTERNET
|
|
||||||
community who have helped shape and debug this package I am pleased to
|
|
||||||
announce version 1.3-pl3 of the sysklogd package.
|
|
||||||
|
|
||||||
This package implements two system log daemons. The syslogd daemon is
|
|
||||||
an enhanced version of the standard Berkeley utility program. This
|
|
||||||
daemon is responsible for providing logging of messages received from
|
|
||||||
programs and facilities on the local host as well as from remote
|
|
||||||
hosts. The klogd daemon listens to kernel message sources and is
|
|
||||||
responsible for prioritizing and processing operating system
|
|
||||||
messages. The klogd daemon can run as a client of syslogd or
|
|
||||||
optionally as a standalone program.
|
|
||||||
|
|
||||||
This package is the culmination of about two years of experience and
|
|
||||||
bug reports on the 1.2 version from both the INTERNET and our
|
|
||||||
corporate Linux networks. The utilities in this package should provide
|
|
||||||
VERY reliable system logging. Klogd and syslogd have both been stress
|
|
||||||
tested in kernel development environments where literally hundreds of
|
|
||||||
megabytes of kernel messages have been blasted through them. If either
|
|
||||||
utility should fail I would appreciate a report and debug information
|
|
||||||
so that the bug can be reproduced and squashed.
|
|
||||||
|
|
||||||
This package includes some major improvements. Some of them are listed
|
|
||||||
here:
|
|
||||||
|
|
||||||
* klogd supports on-the-fly kernel address to symbol
|
|
||||||
translations. This requires that a valid kernel symbol map be
|
|
||||||
found at execution.
|
|
||||||
|
|
||||||
* klogd also supports debugging of protection faults which occur
|
|
||||||
in kernel loadable modules.
|
|
||||||
|
|
||||||
* syslogd has better handling of remote logging capabilities.
|
|
||||||
|
|
||||||
* both klogd and syslogd can be controlled through commandline
|
|
||||||
options and signals.
|
|
||||||
|
|
||||||
* both daemons are now FSSTND conform.
|
|
||||||
|
|
||||||
* a syslog.conf(5) manpage is now available.
|
|
||||||
|
|
||||||
* Spaces are now accepted in the syslog configuration
|
|
||||||
file. This should be a real crowd pleaser.
|
|
||||||
|
|
||||||
* Syslogd now uses dynamic allocation of logging output
|
|
||||||
descriptors. There is no longer a static limit on the number
|
|
||||||
of log destinations that can be defined.
|
|
||||||
|
|
||||||
* Numerous bug fixes and code cleanups.
|
|
||||||
|
|
||||||
The new release can be obtained from either tsx-11.mit.edu or
|
|
||||||
sunsite.unc.edu.
|
|
||||||
|
|
||||||
Thanks again to everyone who has contributed ideas, patches and bug
|
|
||||||
reports. Linux has a superior set of logging utilities thanks to
|
|
||||||
contributions from the entire community.

1.) READ the README.linux file and the accompanying man pages. It will
|
|
||||||
save you some frustration.
|
|
||||||
|
|
||||||
2.) Edit the Makefile for your installation. NOTE that if you have not
|
|
||||||
carried out step 1 you may make choices which could render your
|
|
||||||
system and/or these utilities unusable. Compile the utilities.
|
|
||||||
Compilation has been tested with versions 2.5.8, 2.6.3 and 2.7.0 of
|
|
||||||
the gcc compiler and libc versions 4.5.26 and 4.6.27.
|
|
||||||
|
|
||||||
3.) For proper functioning both of these utilities are best run as root.
|
|
||||||
This is probably not much of a problem since they will probably be
|
|
||||||
started either by init or as part of the rc.* startup process. There
|
|
||||||
may be security concerns with running syslogd as root. Please repeat
|
|
||||||
step 1 if you are unsure of why this may be the case.
|
|
||||||
|
|
||||||
4.) If kernel address to symbol translation is desired there is the
|
|
||||||
possibility that a new kernel will need to be compiled. The patches
|
|
||||||
to delimit kernel addresses requiring translation were added to
|
|
||||||
kernel 1.3.43. If this kernel or a newer kernel is used there is
|
|
||||||
no need to modify the kernel sources.
|
|
||||||
|
|
||||||
If a kernel earlier than this is used the kernel sources will have to
|
|
||||||
be patched. The patch to delimit addresses for translation is included
|
|
||||||
with the sysklogd sources. The necessary modifications are quite
|
|
||||||
generic and should require little modification over a wide range of
|
|
||||||
kernel sources.

Version 1.3 Patch Level 3
|
|
||||||
|
|
||||||
General. ------------------------------------------------------------------
|
|
||||||
Update to documentation including klogd.8 manpage to reflect new features.
|
|
||||||
|
|
||||||
Included patch for modules-2.0.0 package to provide support for signalling
|
|
||||||
klogd of changes in kernel module status.
|
|
||||||
|
|
||||||
klogd ---------------------------------------------------------------------
|
|
||||||
Provided support for signalling klogd to reload static and kernel module
|
|
||||||
symbol information via SIGUSR1 and SIGUSR2.
|
|
||||||
|
|
||||||
Implemented -p switch to cause a reload of kernel module symbol information
|
|
||||||
whenever a protection fault is detected.
|
|
||||||
|
|
||||||
Informative message is printed whenever klogd state change occurs.
|
|
||||||
|
|
||||||
Added -i and -I switches to signal the currently executing klogd daemon
|
|
||||||
to reload symbold information.
|
|
||||||
|
|
||||||
|
|
||||||
Version 1.3 Patch Level 2
|
|
||||||
|
|
||||||
General. ------------------------------------------------------------------
|
|
||||||
Added oops.c and oops_test.c. Oops.c implements a kernel loadable module
|
|
||||||
which will generate a general protection fault. The oops_test.c program
|
|
||||||
generates a test program for exercising the loadable module.
|
|
||||||
|
|
||||||
syslogd ------------------------------------------------------------------
|
|
||||||
Fixed bug resulting in file descriptors being orphaned when syslogd was
|
|
||||||
initialized via signal handler.
|
|
||||||
|
|
||||||
klogd ---------------------------------------------------------------------
|
|
||||||
Bug fix to prevent errors when reading symbol tables with 64 bit addresses.
|
|
||||||
|
|
||||||
Added support for debugging of protection faults occuring in kernel
|
|
||||||
loadable modules.
|
|
||||||
|
|
||||||
|
|
||||||
Version 1.3 Patch Level 1
|
|
||||||
|
|
||||||
General. ------------------------------------------------------------------
|
|
||||||
Cleanups in the Makefile.
|
|
||||||
|
|
||||||
Patches to support compilation in the ALPHA environment. I have not
|
|
||||||
been able to test these personally so if anyone has any feedback I
|
|
||||||
would be interested in hearing from the Linux ALPHA community.
|
|
||||||
|
|
||||||
Spelling and grammar corrections in the man pages.
|
|
||||||
|
|
||||||
syslogd ------------------------------------------------------------------
|
|
||||||
Patch to fix parsing of hostnames in syslogd.c.
|
|
||||||
|
|
||||||
The return value of gethostbyname is now properly checked. This should
|
|
||||||
fix the problems with core dumps when name resolution failed.
|
|
||||||
|
|
||||||
Bounds error fixed when setting the file descriptors for UNIX domain
|
|
||||||
sockets.
|
|
||||||
|
|
||||||
klogd ---------------------------------------------------------------------
|
|
||||||
Error checking and reporting enhanced. I have a couple of reports
|
|
||||||
that klogd is experiencing errors when reading the /proc filesystem.
|
|
||||||
Any additional information would be appreciated.
|
|
||||||
|
|
||||||
The sys_syslog function has been renamed to ksyslog. This was in a
|
|
||||||
set patches for ALPHA support so I am assuming that this is necessary
|
|
||||||
for that environment
|
|
||||||
|
|
||||||
|
|
||||||
Version 1.3
|
|
||||||
|
|
||||||
Numerous changes, performance enhancements, code cleanups and bug fixes.
|
|
||||||
Too many to individually summarize. Have a look at the top of each
|
|
||||||
source file for more information.
|
|
||||||
|
|
||||||
** Default behavior of sysklogd is not to accept any message that
|
|
||||||
is sent via syslog/udp. To allow remote reception add -r to the
|
|
||||||
command-line arguments.
|
|
||||||
|
|
||||||
** Spaces are now accepted in the syslog configuration file. This
|
|
||||||
should be a real crowd pleaser.
|
|
||||||
|
|
||||||
syslogd now uses dynamic allocation of logging output descriptors.
|
|
||||||
There is no longer a static limit on the number of log destinations
|
|
||||||
that can be defined.
|
|
||||||
|
|
||||||
klogd supports on-the-fly kernel address to symbol translations.
|
|
||||||
This requires that a valid kernel symbol map be found at execution.
|
|
||||||
|
|
||||||
** The default level for console log messages was changed to 6. This
|
|
||||||
means that kernel messages with a priority less than or equal to 5
|
|
||||||
(KERN_NOTICE) will be logged to the console.
|
|
||||||
|
|
||||||
This item has been flagged because it results in a behavior
|
|
||||||
change which will be different if version 1.3 replaces an
|
|
||||||
existing 1.2 binary. Linus strongly suggested that this
|
|
||||||
behavior be changed and in the 1.3.3x kernels Linus in fact
|
|
||||||
made it impossible to set the console log level lower than
|
|
||||||
about 5.
|
|
||||||
|
|
||||||
There were good reasons from his perspective for doing so.
|
|
||||||
The most troublesome being that user's of packaged
|
|
||||||
distributions were not able to generate register dumps with
|
|
||||||
the kernel debugging keys, most notably altgr-SCRLCK.
|
|
||||||
|
|
||||||
If a kernels prior to 1.3.3x are being used the klogd daemon
|
|
||||||
invocation must be changed to something like: klogd -c 1
|
|
||||||
|
|
||||||
This will turn off logging of kernel messages to the console.
|
|
||||||
If you understand the ramifications of this the 1.3.3x kernels
|
|
||||||
can be patched to allow the suppression of console log
|
|
||||||
messages. It is important to be cognizant of the effects of
|
|
||||||
these changes. None the least of which is that Linus and Alan
|
|
||||||
will yell at you if you complain about not being able to
|
|
||||||
generate kernel debugging information.. :-)
|
|
||||||
|
|
||||||
---------------------------------------------------------------------------
|
|
||||||
Version 1.2
|
|
||||||
Fixes to both klogd and syslogd so that the package will compile without
|
|
||||||
errors due to the vararg procedures.
|
|
||||||
|
|
||||||
Modified pid files produced so that the names of the files are
|
|
||||||
klogd.pid and syslogd.pid respectively.
|
|
||||||
|
|
||||||
Fixed bug in klogd which prevented output from being directed to a file
|
|
||||||
when the program was compiled to auto-background itself. In the
|
|
||||||
auto-backgrounding configuration the forked process was closing all its
|
|
||||||
file descriptors which was causing the errant behavior.
|
|
||||||
|
|
||||||
Modified signal handling in klogd so that all signal are set to ignored
|
|
||||||
before establishing specific signal handlers.
|
|
||||||
|
|
||||||
Fixed bug in syslogd which was causing a delay in opening of the /dev/log
|
|
||||||
UNIX domain socket. This should correct the race condition which was
|
|
||||||
preventing klogd from properly logging kernel messages when the two
|
|
||||||
daemons were started in rapid succession.
|
|
||||||
|
|
||||||
Modified the closing/opening of file descriptors when syslogd was
|
|
||||||
compiled with auto-backgrounding support. Closes the potential for
|
|
||||||
a somewhat obscure bug caused by the /dev/log socket being opened on
|
|
||||||
fd 0.
|
|
||||||
|
|
||||||
Changed the names of the man pages from an extension of 1 to 8.
|
|
||||||
---------------------------------------------------------------------------
|
|
||||||
Version 1.1
|
|
||||||
Extensive changes and additional functionality added to klogd. Please
|
|
||||||
see sources and man-pages for documentation.
|
|
||||||
|
|
||||||
Fixed bugs in both syslogd and klogd with respect to fragmented
|
|
||||||
message re-assembly. Bootup messages should now be display properly.
|
|
||||||
|
|
||||||
Fixed bug in syslogd which prevented proper logging of messages with
|
|
||||||
priority classes of none and emerg.
|
|
||||||
|
|
||||||
Fixed bug which caused core dump when messages were logged to users.
|
|
||||||
Also fixed bug with messages to login type of LOGIN.
|
|
||||||
|
|
||||||
Fixed problem with zombies being left when messages were logged to
|
|
||||||
multiple users.
|
|
||||||
|
|
||||||
Enhanced functionality of syslog_tst program.
|
|
||||||
|
|
||||||
Added man-pages.
