Description Jerry James 2009-10-08 19:40:11 UTC
Description of problem:
Thanks for the mcelog update.  Now, instead of getting email once per hour about the record length mismatch, I'm getting email once per hour saying "mcelog: Cannot open /dev/mem for DMI decoding: Permission denied". :-)  At the same time, setroubleshoot reports an AVC denial.  Here is a sample:

node=localhost.localdomain type=AVC msg=audit(1255028461.197:22962): avc: denied {read} for pid=4650 comm="mcelog" name="mem" dev=tmpfs ino=3086 scontext=system_u:system_r:dmesg_t:s0-s0:c0.c1023 tcontext=system_u:object_r:memory_device_t:s0 tclass=chr_file

node=localhost.localdomain type=SYSCALL msg=audit(1255028461.197:22962): arch=c000003e syscall=2 success=yes exit=0 a0=409e28 a1=0 a2=1000 a3=2 items=0 ppid=4649 pid=4650 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=5 comm="mcelog" exe="/usr/sbin/mcelog" subj=system_u:system_r:dmesg_t:s0-s0:c0.c1023 key=(null)

Version-Release number of selected component (if applicable):

How reproducible:
Once per hour.

Steps to Reproduce:
1. Install mcelog
2. Wait an hour
Actual results:
mcelog does not have permission to access /dev/mem and so reports failure.  Additionally, setroubleshoot reports the failure.

Expected results:
mcelog runs without errors.
