[Bug 1053217] Re: gdm leaking filehandles, causing too many open files

2013-07-23 Thread Stuart Longland 
Hi,

Is there any possibility of this patch being reviewed and included in
the Ubuntu 10.04 series?  We just had the customer at this site ring up
complaining that they couldn't log in today.  Turns out something
reverted our patched gdm package back to the original Ubuntu one.

Think: big industrial system, and when this problem occurs we have to
boot everyone off to restart gdm.  It was good until the old package got
instated then the service restarted, causing the old problem to occur
once more.  This is our problem, but you could help us a little if you
put out an updated gdm binary.

Or, as a work around: maybe tell us a way we can stop the update manager
from messing with the one we have now.

The original patch is linked in the original post, my revised patch is
supplied, and I've given detail on how to reproduce the problem and how
to check if the problem is fixed.  Is there anything else I need to
supply in order to get this bug resolved?

Okay, I can confirm this would appear to fix the problem.

Test procedure:

1. Log in remotely to the affected machine using ssh, run the following
command:

   $ sudo watch ls -l /proc/$( pidof gdm-binary )/fd

2. Start a remote X session with that host (through Xnest, plain X,
whatever)... observe that new files are opened.

3. Close the X session, observe that the files are not removed from the
list.  In my case, this looked like this:

Vanilla Ubuntu gdm build.

Now, build gdm with the given patch here, re-start gdm, and try again
with the same procedure.  In my case, I see:
