Description Daniel Scott 2009-12-09 02:34:38 UTC

SELinux is preventing /usr/bin/iceauth "read" access on dcopPfMg8b.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by iceauth. It is not expected that this access
is required by iceauth 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

Comment 1 Daniel Walsh 2009-12-09 14:20:58 UTC
Could you check

rpm -q selinux-policy-targeted

Comment 2 Daniel Scott 2009-12-09 14:54:08 UTC
I'm not certain, because I can't access that machine at the moment, but I'm pretty sure that it's:


It should have downloaded that update early this morning. I can confirm tonight if you need.

Comment 3 Daniel Walsh 2009-12-09 15:29:09 UTC
THe question I have is how are you running as iceauth_t?  The transition from unconfined_t->iceauth_t was removed in updates.

Are you using confined users?

Comment 4 Daniel Scott 2009-12-09 15:39:26 UTC
Nope, no confined users. Unless that was set as the default?

Comment 5 Daniel Walsh 2009-12-09 16:38:42 UTC
0# sesearch -A -t iceauth_t -p transition | grep unconfined
   allow unconfined_execmem_t iceauth_t : process { transition getattr } ; 
   allow unconfined_java_t iceauth_t : process { transition getattr } ; 
   allow unconfined_mono_t iceauth_t : process { transition getattr } ; 

Ok I guess you can get there from java, mono or execmem apps.

I will add the required access.

You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
