Bug 450373

Sorry, submitted too early. So,

SELinux is preventing cyphesis from creating log file

Description of problem:
I see following avc deny when starting cyphesis
host=nat.tortilla.ru type=AVC msg=audit(1212820072.648:139): avc: denied {
append } for pid=4309 comm="cyphesis" name="cyphesis_event.log" dev=sdd3
ino=2588853 scontext=unconfined_u:system_r:cyphesis_t:s0
tcontext=system_u:object_r:var_log_t:s0 tclass=file host=nat.tortilla.ru
type=SYSCALL msg=audit(1212820072.648:139): arch=40000003 syscall=5 success=no
exit=-13 a0=9ea4fac a1=8441 a2=1b6 a3=440 items=0 ppid=4308 pid=4309 auid=502
uid=493 gid=487 euid=493 suid=493 fsuid=493 egid=487 sgid=487 fsgid=487
tty=(none) ses=1 comm="cyphesis" exe="/usr/bin/cyphesis"
subj=unconfined_u:system_r:cyphesis_t:s0 key=(null) 

Version-Release number of selected component (if applicable):
cyphesis-0.5.15-8.fc9.i386

How reproducible:
Always.

Additional info:
In previous cyphesis-selinux package cyphesis was allowed to var_log_t, but in
new policy cyphesis_log_t was introduced. But gen_context on /var/log/cyphesis
wasn't added. So, I'm guessing, it should be added there.

P.S. As a workaround, I've made
chcon -t cyphesis_log_t /var/log/cyphesis /var/log/cyphesis/cyphesis_event.log
after this, all seems to work fine.

I'm unable to reproduce this.  On my F9-i386 system, /var/log/cyphesis has:

# ls -Zd /var/log/cyphesis
drwxr-xr-x  cyphesis cyphesis system_u:object_r:var_log_t:s0   /var/log/cyphesis

...and the log file has:

# ls -Z /var/log/cyphesis
-rw-r--r--  cyphesis cyphesis unconfined_u:object_r:cyphesis_log_t:s0
cyphesis_event.log

cyphesis has no trouble creating and writing to the log file at startup when
selinux is in Enforcing mode.  What version of selinux-policy-targeted are you
using?

# rpm -q selinux-policy-targeted
selinux-policy-targeted-3.3.1-42.fc9.noarch

In my system it is newer:
selinux-policy-targeted-3.3.1-55.fc9.noarch

I still can't reproduce this with a clean F-9 install+updates and
selinux-policy-targeted-3.3.1-64.fc9.noarch

Is it possible that you have a leftover cyphesis-selinux package installed?  Or
maybe the cyphesis-selinux policies are still loaded and you need a reboot to
unload them?

Oh. Right, to be sure, I made policy reload and reinstalled the package. Now,
cyphesis is able to create log labeled cyphesis_log_t and write to it. Other
cyphesis selinux bug distracted me and I misreaded your comment #3, sorry.

In my system, log had var_log_t after update. In new installations all is
working fine.

But I think that file context for /var/log/cyphesis/cyphesis_event.log should be
added into selinux policy - it will allow to do restorecon on update and will
preserve label if user decides to do relabel himself.

Sometimes, for unknown reason, logfile selunux type got reset to standard
var_log_t. May be something is making restorecon on it?

Anyway, policy should be updated.
