Fixed in selinux-policy-3.10.0-3.fc16 *** Bug 713908 has been marked as a duplicate of this bug. *** This is also a problem in Fedora 15. Will this be backported? (In reply to comment #3) > This is also a problem in Fedora 15. Will this be backported? Dan or Miroslav, will this fix be applied to F15? It continues to be a problem which, with the sheer number of AVC denials, is almost like a DOS attack, as the number of deferreals increase, the number of AVCs generated (and emailed) create further deferrals and moreAVCs. Miroslav can you back port the fix. |
SELinux is preventing /usr/libexec/postfix/qmgr from 'write' accesses on the dossier /var/spool/postfix/deferred/8. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that qmgr should be allowed write access on the 8 directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep qmgr /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:postfix_qmgr_t:s0 Target Context system_u:object_r:postfix_spool_maildrop_t:s0 Target Objects /var/spool/postfix/deferred/8 [ dir ] Source qmgr Source Path /usr/libexec/postfix/qmgr Port <Inconnu> Host (removed) Source RPM Packages postfix-2.8.3-1.fc16 Target RPM Packages Policy RPM selinux-policy-3.10.0-2.fc16 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.0-0.rc5.git0.1.fc16.x86_64 #1 SMP Tue Jun 28 04:06:31 UTC 2011 x86_64 x86_64 Alert Count 118 First Seen lun. 04 juil. 2011 10:49:10 CEST Last Seen lun. 04 juil. 2011 16:46:01 CEST Local ID cd40ac75-014f-4d00-8b6c-5f809dc8da01 Raw Audit Messages type=AVC msg=audit(1309790761.410:16833): avc: denied { write } for pid=21272 comm="qmgr" name="8" dev=dm-1 ino=151244 scontext=system_u:system_r:postfix_qmgr_t:s0 tcontext=system_u:object_r:postfix_spool_maildrop_t:s0 tclass=dir type=SYSCALL msg=audit(1309790761.410:16833): arch=x86_64 syscall=rename success=no exit=EACCES a0=7fc801d41440 a1=7fc801d420d0 a2=7fc801d44750 a3=7fff41be1b20 items=0 ppid=1481 pid=21272 auid=4294967295 uid=89 gid=89 euid=89 suid=89 fsuid=89 egid=89 sgid=89 fsgid=89 tty=(none) ses=4294967295 comm=qmgr exe=/usr/libexec/postfix/qmgr subj=system_u:system_r:postfix_qmgr_t:s0 key=(null) Hash: qmgr,postfix_qmgr_t,postfix_spool_maildrop_t,dir,write audit2allow #============= postfix_qmgr_t ============== #!!!!
