Red Hat Product Errata RHBA-2010:0211 0 normal SHIPPED_LIVE sysklogd bug fix update 2010-03-29 12:29:55 UTC

Description Tomas Smetana 2008-11-25 10:28:29 UTC 
Description of problem:
Using -m option with nonzero argument will result in the bogus error messages being logged.  This is caused by a bug in sysklogd:  the errno value of select is checked after it has been reset (from EINTR to EINVAL) by the functions that log the "MARK" message.

Version-Release number of selected component (if applicable):
sysklogd-1.4.1-44.el5

How reproducible:
always

Steps to Reproduce:
1. start 'syslogd -m 2 -r -d'
2. let it run for several minutes
3. look into /var/log/messages
  
Actual results:
Nov 25 09:00:18 localhost -- MARK --
Nov 25 09:00:18 localhost syslogd: select: Invalid argument
Nov 25 09:02:18 localhost -- MARK --
Nov 25 09:02:18 localhost syslogd: select: Invalid argument
Nov 25 09:04:18 localhost -- MARK --
Nov 25 09:04:18 localhost syslogd: select: Invalid argument
Nov 25 09:06:18 localhost -- MARK --

Expected results:
Nov 25 09:00:18 localhost -- MARK --
Nov 25 09:02:18 localhost -- MARK --
Nov 25 09:04:18 localhost -- MARK --
Nov 25 09:06:18 localhost -- MARK --

Proposed patch

Avoids problem by storing the errno from select to the new variable.
Comment 3 RHEL Program Management 2009-03-26 17:13:39 UTC 
This request was evaluated by Red Hat Product Management for
inclusion, but this component is not scheduled to be updated in
the current Red Hat Enterprise Linux release. If you would like
this request to be reviewed for the next minor release, ask your
support representative to set the next rhel-x.y flag to "?".
Comment 5 Peter Vrabec 2009-11-30 14:46:23 UTC 
It seems the patch is not needed anymore. I couldn't reproduce this problem on RHEL5.4. I suspect that this issue was fixed by one of glibc updates.
Comment 6 Peter Vrabec 2009-11-30 14:50:32 UTC 
I'm closing this bug report. If the problem persist, please reopen it.
