Description Michael Blandford 2003-05-16 13:30:49 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030312

Description of problem:
gdm fails to pass the name of the shell.  This is a common oversight by
people who do not understand or expect wrappers and other programs
that switch behavior based on the name passed to argv[0] using exec
functions.



Version-Release number of selected component (if applicable):
2.2.3.1-20

How reproducible:
Always

Steps to Reproduce:
1. Set your login shell to a wrapper program that calls another program based on
name.
2. Log in
3.
    

Actual Results:  You would get logged out immediately.  It makes using local
display and remote via xdmcp impossible.

Additional info:

I will be including a patch to fix the problem.

Patch to resolve the problem

Comment 2 Havoc Pennington 2003-05-16 17:03:04 EDT

hmm, bugzilla got confused - in the comment, the attachment ID is wrong 
(91736 should be 91735 as in the attachment list)

anyhow, cc'ing gdm author.

Comment 3 George Lebl 2003-05-16 23:41:27 EDT

I fixed this bug in CVS.  I believe redhat doesn't have this bug does it?  I
thought redhat just reworked this part of the source to force bash always.

Comment 4 Havoc Pennington 2003-05-17 00:08:41 EDT

Ah, sorry about that. We probably don't have this bug or any change to this part
of the source at all anymore; the bug is reported against Advanced Server 2.1
which is GNOME 1.x.

Looking at the current code, it's completely different (just runs 
a script, doesn't invoke the user's shell directly). This will be 
in the next release of RHEL.
