This is hard to fix. Any confined domain that is started in a random directory attempts to search/getattr on the current working directory. If you ran passwd from / or your homedir you would not get this avc. You can allow this for now. # audit2allow -M mypol -l -i /var/log/audit/audit.log # semodule -i mypol.pp Fixed in selinux-policy-3.3.1-75.fc9.noarch Bugzilla tells me that I need to verify that this is fixed. So ... I verified that this is fixed. Thank you, Daniel. |
Description of problem: I don't know if this is a passwd bug or an selinux-policy bug, so I'm filing against the latter. I just changed my password with /usr/bin/passwd. The password change was successful, but just as the program exited, I got this AVC denial: host=localhost.localdomain type=AVC msg=audit(1212440781.663:61): avc: denied { search } for pid=17579 comm="passwd" name="tmp" dev=dm-0 ino=253457 scontext=unconfined_u:unconfined_r:passwd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:tmp_t:s0 tclass=dir host=localhost.localdomain type=SYSCALL msg=audit(1212440781.663:61): arch=c000003e syscall=6 success=no exit=-13 a0=6ad0a5 a1=7fffedc9b990 a2=7fffedc9b990 a3=7f16e5c81810 items=0 ppid=17572 pid=17579 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=pts2 ses=1 comm="passwd" exe="/usr/bin/passwd" subj=unconfined_u:unconfined_r:passwd_t:s0-s0:c0.c1023 key=(null) Version-Release number of selected component (if applicable): selinux-policy-3.3.1-55.fc9 passwd-0.75-2.fc9 How reproducible: I have not tried to reproduce it. Steps to Reproduce: 1. Run /usr/bin/passwd as a non-root user Actual results: AVC denial Expected results: No AVC denial Additional info: Setroubleshoot suggested trying to relabel /tmp. I ran restorecon -v on /tmp, with no change.
