Bug 93484 – proftpd-1.2.10-r2 segfaults on ppc64 because of mod_delay

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Harald Welte 2005-05-21 16:00:33 UTC]

proftpd-1.2.0-r2 segfaults immediately haver having received the username (via
USER command from the client).  The problem disappears when it is compiled
without mod_shaper.

The ebuild already contains a line like
#Mod shaper is giving problems on some machines

so if it is known to cause problems, why isn't it disabled on those
architecture[s], such as ppc64?



Reproducible: Always
Steps to Reproduce:
1. emerge the respective ebuild
2. start proftpd
3. login from some client

Actual Results:  
the forked daemon exits with SIGSEGV

Expected Results:  
the forked daemon should prompt for a password and continue

sorry, proftpd-1.2.10-r2 is the correct version.

[Comment 2 Harald Welte 2005-05-21 16:19:15 UTC]

Ok, sorry for that wrong report.  Further debugging resulted in the following
news:  It's actually mod_delay that causes the segfaults.  If I modify the
ebuild (see attachment) to not include mod_delay, it works like a charm.

[Comment 3 Harald Welte 2005-05-21 16:20:21 UTC]

Created attachment 59500 [details]
modified ebuild to remove mod_delay

[Comment 4 Harald Welte 2005-05-22 01:40:12 UTC]

why did you change my correction?  This is about mod_delay, not about mod_shaper
(my initial mistake).

[Comment 5 Jakub Moc (RETIRED) 2005-05-22 03:21:46 UTC]

mod_delay is no longer there in 1.2.10-r3, might be better to just mark that one
stable for ppc64 instead. 

[Comment 6 Gustavo Felisberto (RETIRED) 2005-06-06 04:02:25 UTC]

Guys, please try -r3 and mark it stable.

[Comment 7 Markus Rothe (RETIRED) 2005-06-06 13:19:29 UTC]

thanks for report. this problem was not known and proftpd worked for me. I just
didn't used that mod.

-r3 stable on ppc64.
