Package: kernel-source-2.6.8
Version: 2.6.8-16sarge6
Severity: normal
*** Please type your report below this line ***
Hi,
Hope I'm reporting this to the correct place...
This is a straight sarge system. Hardware info below.
The problem I observe is that -
when /etc/cron.daily/sysklogd runs,
/var sometimes fills up,
because the /var/log/syslog accumulates tens of thousands of errors like:
Feb 5 11:18:56 myhost kernel: __find_get_block_slow() failed.
block=204803, b_blocknr=18446744073709551615
Feb 5 11:18:56 myhost kernel: b_state=0x00000000, b_size=1024
Feb 5 11:18:56 myhost kernel: device blocksize: 1024
Feb 5 11:18:56 myhost kernel: 4
Feb 5 11:18:56 myhost kernel: device blocksize: 1024
Possibly other things trigger this as well but certainly running sysklogd
does; the errors are correlated with the time /etc/cron.daily runs, and
I was able to produce them by running each script in /etc/cron.daily
in turn - when I hit sysklogd, the errors appeared.
I thought this could be CVE-2006-5757,
see for example the change log for http://lwn.net/Alerts/209028/,
and also SUSE-SA:2006:079 http://lwn.net/Alerts/215225/
however I don't see how I could be accessing an ISO9660 filesystem from
sysklogd, as far as I can tell it's only accessing and ext2 fs.
