** Description changed: Syslog output: Apr 29 10:59:06 host12 dovecot: imap(foobar): Error: fcntl(unlock) locking failed for file /home/foobar/Maildir/dovecot.index.log: No such file or directory Apr 29 10:59:06 host12 dovecot: imap(foobar): Error: fstat() failed with file /home/foobar/Maildir/dovecot.index.log: No such file or directory Apr 29 10:59:37 dovecot: last message repeated 122 times Apr 29 11:00:38 dovecot: last message repeated 248 times Apr 29 11:01:54 dovecot: last message repeated 203 times audit.log, lots of entries similar to the following: type=AVC msg=audit(1335712674.515:655016): apparmor="ALLOWED" operation="getattr" parent=10922 profile="/usr/sbin/dovecot//null-107 //null-10b//null-118" name="/home/foobar/Maildir/.foobar/dovecot.index.log" pid=10937 comm="imap" requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000 The apparmor policy is as shipped with 12.04. The strange thing here is that audit.log says that the access was allowed and the apparmor policy has "flags=(complain)", but the imap server still fails accessing some files in the Maildir folders. Workaround: # ln -s /etc/apparmor.d/usr.sbin.dovecot /etc/apparmor.d/disable/ After disabling the usr.sbin.dovecot apparmor policy everything works fine. There is no need to disable the "usr.lib.dovecot.imap" policy. It looks like the imap process is incorrectly running under the dovecot main daemon's apparmor profile. And for some odd reason the profile is enforcing things even though it should be in "complain" mode. What are these "//null-NNN/" strings in the logged apparmor profile name? I do not know apparmor well enough to debug this further at this point. Someone else has encountered this also, see thread at: http://comments.gmane.org/gmane.mail.imap.dovecot/60533 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: dovecot-imapd 1:2.0.19-0ubuntu1 ProcVersionSignature: User Name 3.2.0-24.37-virtual 3.2.14 Uname: Linux 3.2.0-24-virtual x86_64 ApportVersion: 2.0.1-0ubuntu7 Architecture: amd64 Date: Wed May 9 18:36:11 2012 ProcEnviron: SHELL=/bin/bash TERM=screen LANG=en_US.UTF-8 SourcePackage: dovecot UpgradeStatus: Upgraded to precise on 2012-04-27 (12 days ago) + --- + ApportVersion: 2.0.1-0ubuntu8 + Architecture: amd64 + DistroRelease: Ubuntu 12.04 + InstallationMedia: Ubuntu-Server 12.04 LTS "Precise Pangolin" - Release amd64 (20120424.1) + Package: apparmor 2.7.102-0ubuntu3.1 + PackageArchitecture: amd64 + ProcEnviron: + TERM=linux + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcKernelCmdline: BOOT_IMAGE=/boot/vmlinuz-3.2.0-23-generic root=UUID=7e6df5b7-d31e-4757-a388-f4f477187a63 ro + ProcVersionSignature: Ubuntu 3.2.0-23.36-generic 3.2.14 + Tags: precise + Uname: Linux 3.2.0-23-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: ** Attachment added: "ApparmorPackages.txt" https://bugs.launchpad.net/bugs/997269/+attachment/3216655/+files/ApparmorPackages.txt -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dovecot in Ubuntu. https://bugs.launchpad.net/bugs/997269 Title: dovecot imap broken by apparmor policy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/997269/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
