Miroslav could you add optional_policy(` dovecot_domtrans_deliver(postfix_local_t) ') Ales can you try the following commands and see if you get any other AVC messages # cat > mydovecot.te << _EOF policy_module(mydovecot,1.0) gen_require(` type postfix_local_t; ') dovecot_domtrans_deliver(postfix_local_t) _EOF # make -f /usr/share/selinux/devel/Makefile # semodule -i mydovecot.pp This issue should be fixed in the latest RHEL6 selinux-policy. selinux-policy-3.7.19-31.el6.noarch The problem is /usr/libexec/dovecot/dovecot-lda has bad label with selinux-policy-targeted-3.7.19-29.el6. Ales, please update your selinux-policy and re-test it. Thanks. I am closing it as duplicate of #612406 bug. *** This bug has been marked as a duplicate of bug 612406 *** |
Description of problem: I have dovecot configured as LDA in postfix: mailbox_command = /usr/libexec/dovecot/deliver Dovecot then runs in postfix's context, confusing selinux: type=AVC msg=audit(1279613115.572:43903): avc: denied { search } for pid=31012 comm="deliver" name="dovecot" dev=dm-0 ino=2223944 scontext=unconfined_u:system_r:postfix_local_t:s0 tcontext=system_u:object_r:dovecot_var_run_t:s0 tclass=dir type=SYSCALL msg=audit(1279613115.572:43903): arch=c000003e syscall=42 success=no exit=-13 a0=6 a1=7fff66a2cf20 a2=6e a3=118 items=0 ppid=31004 pid=31012 auid=0 uid=504 gid=504 euid=504 suid=504 fsuid=504 egid=504 sgid=504 fsgid=504 tty=(none) ses=676 comm="deliver" exe="/usr/libexec/dovecot/dovecot-lda" subj=unconfined_u:system_r:postfix_local_t:s0 key=(null) type=AVC msg=audit(1279613115.576:43904): avc: denied { search } for pid=31012 comm="doveconf" name="dovecot" dev=dm-0 ino=393984 scontext=unconfined_u:system_r:postfix_local_t:s0 tcontext=system_u:object_r:dovecot_cert_t:s0 tclass=dir type=SYSCALL msg=audit(1279613115.576:43904): arch=c000003e syscall=2 success=yes exit=128 a0=1815b86 a1=0 a2=1815b86 a3=0 items=0 ppid=31004 pid=31012 auid=0 uid=504 gid=504 euid=504 suid=504 fsuid=504 egid=504 sgid=504 fsgid=504 tty=(none) ses=676 comm="doveconf" exe="/usr/bin/doveconf" subj=unconfined_u:system_r:postfix_local_t:s0 key=(null) The mail delivery still works though. Version-Release number of selected component (if applicable): selinux-policy-targeted-3.7.19-29.el6.noarch dovecot-2.0-0.8.beta6.20100630.el6.x86_64 postfix-2.6.6-2.el6.x86_64 How reproducible: always Steps to Reproduce: 1. configure dovecot as LDA in postfix 2. send mail to local user 3. flush queues to force mail delivery
