Description Bert DeKnuydt 2019-05-14 07:27:52 UTC

Description of problem:

Autofs 5.1.5-2 and up immediately coredumps on any line in 
/etc/auto.master containing a multi-map

Version-Release number of selected component (if applicable):

autofs-5.1.5-3.fc30.x86_64     Broken (=current)
autofs-5.1.5-2.fc30.x86_64     Broken

autofs-5.1.5-1.fc30.x86_64     Okay (= last version with hesiod compiled in)
autofs-5.1.4-21.fc29.x86_64    Okay

How reproducible:

Always and immediate.

Steps to Reproduce:
1. Comment out everything in /etc/auto.master and add one line:

   /test multi /etc/auto.test -- /etc/auto.test1

2. Make /etc/auto.test contain one line:

   one -fstype=bind :/usr/data

   Make /etc/auto.test1 contain one line:

   two -fstype=bind :/usr/data/tmp

3. systemctl restart autofs

Actual results:

----
[root@funen tmp]# systemctl start autofs
Job for autofs.service failed because a fatal signal was delivered causing the control process to dump core.
See "systemctl status autofs.service" and "journalctl -xe" for details.
----

In the journal, there is:

----
-- 
-- The unit UNIT has successfully entered the 'dead' state.
May 14 09:13:08 funen.esat.kuleuven.be systemd[1]: autofs.service: Main process exited, code=dumped, status=11/SEGV
-- Subject: Unit process exited
-- Defined-By: systemd
-- Support: https://lists.freedesktop.org/mailman/listinfo/systemd-devel
----

Expected results:

Successful start, and correct behaviour when for 'ls -l /test/one' resp. 'ls -l /test/two' 

Additional info:

*) Nothing is logged

*) Just the word 'multi' alone is enough to cause a crash.

*) As the difference between the last-good and first-bad (according to what is in Koji) is only

----
* Mon Nov 05 2018 Ian Kent <ikent> - 
1:5.1.5-2 - update spec file to build without hesiod.
----

it should be related to the removal of hesiod.  Not that there's no hesiod used here at all.

Greetings, Bert.
