Description Anthony Messina 2007-04-20 13:15:12 UTC
Description of problem:
The clamd.amavisd service runs as the amavis user under the clamd_t context. 
Since it is installed as part of amavisd-new, it should be able to run with
access to some areas labeled as amavis_t.

Version-Release number of selected component (if applicable):
selinux-policy-2.4.6-57.fc6
amavisd-new-2.4.4-2.fc6
clamav-server-sysv-0.88.7-2.fc6
clamav-update-0.88.7-2.fc6
clamav-data-0.88.7-2.fc6
clamav-server-0.88.7-2.fc6
clamav-lib-0.88.7-2.fc6

How reproducible:
Every time

Steps to Reproduce:
1. Start amavisd
2. Start clamd.amavisd
  
Actual results:
avc: denied { create } for comm="clamd.amavisd" dev=sda2 egid=104 euid=103
exe="/usr/sbin/clamd" exit=5 fsgid=104 fsuid=103 gid=104 items=0
name="clamd.pid" pid=3137 scontext=system_u:system_r:clamd_t:s0 sgid=104
subj=system_u:system_r:clamd_t:s0 suid=103 tclass=file
tcontext=system_u:object_r:amavis_var_run_t:s0 tty=(none) uid=103

Expected results:
No denial should exist

Additional info:
Running in permissive mode.

Comment 1 Daniel Walsh 2007-04-20 14:50:53 UTC
So clamd is trying to create its pid file under /var/run/amavis?

Comment 2 Anthony Messina 2007-04-20 15:16:56 UTC
yes, it want's to create it's clamd.pid file there.  it wants create and getattr
perms.  i assume this is so it can create the file, then check if it's there to
determine if it's running (for init, i think).

Comment 3 Daniel Walsh 2007-05-17 16:43:04 UTC
Fixed in selinux-policy-2.4.6-69
