Gdm opens a file descripor for logging and then uses dup2(2). However,
the origianl file descriptor opened is not closed. The leak occurs
when a user logs out of X and will continue untill gdm is restarted,
usually when the system is rebooted. I believe this effects all versions of gdm to date. The following patch 
fixes this problem:

Fixed in 7.0

After comparing your gdm-2.0beta2-fdleak.patch from 7.0 and horms' patch above,
you will find that you fixed one leak but not the other.  The patch above also
affects daemon/server.c, which yours does not.

This bug should be reopened until the issue is fixed completely.

Comment 3 Havoc Pennington 2001-01-03 00:01:08 UTC
Ah, thanks. I went ahead and changed the patch to have the second close().

Comment 4 Michael Jennings (KainX) 2001-01-03 00:09:08 UTC
Any idea when we can expect a new SRPM, or what it will be called?  Thanks....

It'll be in the next beta
