Description Antonio A. Olivares 2009-09-13 16:01:28 UTC

The following was filed automatically by setroubleshoot:

Summary:

SELinux is preventing /usr/sbin/abrtd "read" access on time.

Detailed Description:

[abrtd has a permissive type (abrt_t). This access was not denied.]

SELinux denied access requested by abrtd. It is not expected that this access is
required by abrtd and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

audit2allow suggests:

#============= abrt_t ==============
allow abrt_t var_t:file { read open };

Comment 1 Daniel Walsh 2009-09-14 16:23:33 UTC

What file named time is abrt trying to read under /var?

Is this file under /var/cache/abrt?

Comment 2 Michael S. 2009-10-18 23:46:17 UTC

this seems quite similar to what i see in my log :

# grep 1255903177.653:14824  /var/log/audit/audit.log
type=AVC msg=audit(1255903177.653:14824): avc:  denied  { read } for  pid=1548 comm="abrtd" path="/var/cache/abrt/kerneloops-1254406517-13/time" dev=dm-1 ino=271119 scontext=system_u:system_r:abrt_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file
type=SYSCALL msg=audit(1255903177.653:14824): arch=40000003 syscall=3 success=yes exit=0 a0=8 a1=9c64178 a2=1fff a3=bfd428dc items=0 ppid=1 pid=1548 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="abrtd" exe="/usr/sbin/abrtd" subj=system_u:system_r:abrt_t:s0 key=(null)

so yes, the file is under /var/cache/abrt/ , in /var/cache/abrt/kerneloops-1254406517-13/time to be exact.

here is the selinux context, if this help :

# ls -lZ /var/cache/abrt/kerneloops-1254406517-13/time
-rw-r--r--. root root system_u:object_r:var_t:s0       /var/cache/abrt/kerneloops-1254406517-13/time

# ls -lZd /var/cache/abrt/kerneloops-1254406517-13
drwx------. root root system_u:object_r:var_t:s0       /var/cache/abrt/kerneloops-1254406517-13

# ls -lZd /var/cache/abrt
drwxrwxrwt. root root system_u:object_r:abrt_var_cache_t:s0 /var/cache/abrt

the file only contains the time of the crash, in second since epoch.

Comment 3 Daniel Walsh 2009-10-19 13:46:19 UTC

I the label is correct now. And abrt can read te file.
You had a labelling problem that as now been fixed.

I am closing this bug as notabug, reopen if this happens again.
