General. ------------------------------------------------------------------
|
|
Please refer to the file debian/changelog.
|
|
|
|
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.
