patch to use "nobody"'s primary group instead of assuming that it's named "nogroup" and going from there (2.67 KB, patch)

Description Nalin Dahyabhai 2006-02-13 22:43:38 UTC
Description of problem:
vol_id attemps to drop privileges to that of the 'nobody' user when it runs, by
switching to the 'nogroup' gid and the 'nobody' uid.  This fails on Fedora
because we don't have a 'nogroup' group.  (It also creates boot delays when
network-using nsswitch modules are in use, but that's a side-effect.)

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

How reproducible:

Steps to Reproduce:
1. Switch on "ldap" for use in "group" lookups in /etc/nsswitch.conf, preferably
with a default /etc/ldap.conf on the system.
2. Reboot.
Actual results:
Debug spew as vol_id tries to look up information about the group.

Expected results:
Quick bootup.

Additional info:
Why not just use the user's primary group ID?

Comment 4 Andreas Bierfert 2006-02-24 15:44:48 UTC

will this hit rawhide anytime soon or is there a test rpm somewhere?

Comment 5 Harald Hoyer 2006-02-24 15:55:51 UTC
already should have with udev-084-4

Comment 6 Ignacio Vazquez-Abrams 2006-02-24 16:39:55 UTC
So in other words you're saying that something completely different is causing
boot issues with udev and LDAP? How do we debug this?

Comment 7 Andreas Bierfert 2006-02-24 17:07:11 UTC
Hm ok... the vol_id error went away here with current udev release but now there
are lots of other errors... Could this by any chance be
related/affected/affecting bug #181305?

Comment 8 Andreas Bierfert 2006-02-26 08:41:45 UTC
With latest udev 084-6 everyting is working. This bug can be closed imho. Thanks.
