[Dovecot] imap segfault in mail-index-sync.c
by Todd Burroughs 10 Apr '05

10 Apr '05

Our support team seems to have caused another crash. They treat this mailbox like a shared one, so there may be a few people accessing it at once. They are mostly using dovecot, but some could be using uw-imap. These are the only two ways that this box is accessed. I know that this doesn't really work with mbox, but it doesn't appear to corrupt the mailbox. It seems to be a good stress test... In this case, it looks like several of them are logged in at once. Here's the log entry and backtrace of the imap process which segfaulted. I'll put a section of logs covering this time at the end, in case it helps. The problem appears to be here in mail-index-sync.c: #define MAIL_INDEX_IS_SYNCS_SAME(index) \ ((index)->sync_log_file_seq == (index)->hdr->log_file_seq && \ (index)->sync_log_file_offset == (index)->hdr->log_file_ext_offset) index->hdr is NULL dovecot: Apr 09 20:52:07 Error: 27413 IMAP(support): Fixed index file /mailhome/new/m/2/support/.imap/INBOX/dovecot.index: recent_messages_count 12 -> 0 dovecot: Apr 09 20:52:11 Error: 27413 IMAP(support): Corrupted transaction log file /mailhome/new/m/2/support/.imap/INBOX/dovecot.index.log: Extension introduction for unknown id 1 dovecot: Apr 09 20:52:11 Error: 27413 IMAP(support): Corrupted index file /mailhome/new/m/2/support/.imap/INBOX/dovecot.index: File too small dovecot: Apr 09 20:52:12 Error: child 27413 (imap) killed with signal 11 Core was generated by `imap'.

[Dovecot] Authentication and the wrong mailbox?
by Rich West 10 Apr '05

10 Apr '05

I just migrated from UW-imap to dovecot last night. After some tweaking of the dovecot.conf file, disabling xinetd's entries, firing up the dovecot daemon, and copying the .mailboxlist to .subscriptions for all users, things looked to be going just fine! I received a call this morning from a user stating that they had all of *my* emails in *their* inbox! They don't know when it happened as their machine POP's email off every 5-10 minutes or so, but we were able to isolate it to a 8hr period last night. Further investigation showed that at some time through the evening, dovecot freaked out during the authentication phase and for some bizzare reason, when the user connected via POP3, they were able to download all of my inbox! Additionally, by the time I was looking in to it, NO users could authenticate via dovecot, and, hence, no one had access to email. Restarting dovecot resolved the issue, but I have my doubts about it being truly resolved. I'm going to run some tests (what little I can think of), but this is the first time I have ever experienced a situation such as this. One thing for UW is that this situation never happened, and I've only had dovecot running for about 13hrs. Any ideas as to how or why this may have happened, and how it can be prevented, would be wonderful. -Rich -- Richard West $14.95 Registrations mailto:rwest@wesmo.com Wesmo Computer Services .com .net .org .tv .cc http://www.wesmo.com Full Domain & Web Hosting .BIZ .INFO & MORE!!

[Dovecot] Outlook express confusion
by Andrew Hutchings 08 Apr '05

08 Apr '05

Hi, This may be a problem with my config file but I am finding that customers (and more importantly my boss) that are using outlook express when using test66/67 (upgraded from test60 + from address patch) are having message reappear after being fully deleted (not just marked) but are unreadable, sometimes blank headers appear too but again no message. Since it is affecting my boss he has told me to go back to test60 or lower, and won't let me find the problem.

[Dovecot] maildir quota management
by Wayne Lovely 08 Apr '05

08 Apr '05

Hi everyone, my name is Wayne Lovely and this is my first post. My company has a need for dovecot to decrement the portion of quota used. The used portion and hard limit will be stored in a central database. Initially I'll just hack in what we need as a proof of concept, but I would like to get some input into what people would really like, such that I can make a good contribution. regards, Wayne Lovely

[Dovecot] 1.0-test67
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ Hopefully better release than last one. Fixes several problems test66 had and also some older problems reported in this list. It also contains a pretty large mbox code cleanup, fixing several problems (especially related to X-IMAP/X-IMAPbase headers) and making it a bit faster. Maybe I'll backport it to 1.0-stable too when it looks like it's stable.. BTW. mbox code is slower than necessary when updating message flags and mbox_lazy_writes=yes, because it reads message headers for each message whose flag is to be changed (in index). Should fix that one soon too..

Hi Chris - Thank you for the reply. > I can't reproduce this in our setup in either 1.0-stable or > 1.0-test66. What's your namespace definition and MAIL= environment? > What does > > 1 LIST "Misc/" "*" > > give you? The LIST command returns what I expect to see (for readability): 2 list "Misc/" "*" * LIST (\HasNoChildren) "/" "Misc/Spam" > Can you 1 SELECT "Misc/Spam" OK? I can select that mailbox as well as others without a problem. Here's what NAMESPACE returns: 3 NAMESPACE * NAMESPACE (("" "/")) NIL NIL My namespace definition in dovecot.conf is as follows: namespace private { separator = / # prefix = # location = inbox = yes # hidden = yes } I didn't have default_mail_env set to anything, but I just tried the following without a change in the STATUS command's behavior: default_mail_env = maildir:/home/%u/Maildir Is there any other information that might help? Thanks, Lawrence

[Dovecot] Linux, Maildir over NFS, Locking problems
by Terrence Martin 08 Apr '05

08 Apr '05

Hi, I am having problems with file locks with my NFS mounted Maildir setup. NFS Client/IMAP Server is RHEL3 clone whitebox and NFS server is a Fedora Core 2 system. Both are running lockd as far as I can tell. dovecot is installed with Dag's latest dovecot RPMs for RHEL3. Time is synced between the two systems. Here is the pertinent log file entry dovecot: Dovecot starting up Apr 7 11:17:42 sentry imap(tmartin): /home/tmartin/Maildir/.subscriptions failed with subscription file file_wait_lock(): No locks available Now what I can find in nfs.txt is that I need to use fnctl is this ".customflags and .subscriptions files require fcntl() locking currently. Many NFS servers don't support it, at least without a separate lockd daemon. These will be fixed later to be NFS-safe by default." My question is am I using fcntl? The only reference I can find in the config refers to mbox formats, but I am using maildir. Setting the one reference to fcntl does not seem to have any effect. Is there a configuration setting to tell the server to use fcntl locks or a way to tell if it is trying to use fcntl locks? Thanks for any tips, Terrence

[Dovecot] 1.0-test66
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ I've still lots of mails in my INBOX and in this list that I should be looking into.. But here's a release that fixes at least some things. Maybe I'll make another one tomorrow.. Most importantly keyword code was changed a lot. It's now faster and less buggy. The keywords are also finally written into mbox, and keyword changes in the mbox are picked up. So upgrading from Dovecot 0.99.x or UW-IMAP (or reverting back to them) doesn't anymore lose the keywords. Maildir still needs 0.99.x-compatible customflags-file and storing the keywords as a..z flags in maildir filename. Hopefully I'll get that done soon, and then we should be nearing 1.0-alpha1 release :) The new keyword code hasn't been tested much, so this might be less stable than earlier versions. - Renamed oe6-fetch-no-newmail workaround to delay-newmail and changed it to work more like the name says: only newmail notifications are skipped and not only for FETCH command. - LDAP crashfixes - Changed FETCH to return smaller items first. Should fix all kmail and Thunderbird problems. Removed tb-negative-fetch workaround as it shouldn't be needed anymore. - Cache file was breaking constantly with test65 - Blocking passdb fixes and proper RPA realm support patches from Andrey - in-memory indexes should be working again if someone wants to use them for some reason (:INDEX=MEMORY) - gzipped mbox plugin http://dovecot.org/patches/1.0/zlib-plugin.tar.gz - SORT crashfix - Some mbox rewriting fixes (should fix some asserts) - etc.
