Description Jay Rishel 2007-09-25 11:18:33 EDT
Description of problem:
/etc/auto.master contains the line:
/apps           /etc/auto_apps
which contains:
pb              -rw     localhost:/export/appl/pkgs/&   # PowerBroker

automount can't mount /apps/pb/ because of the comment: # PowerBroker

This same configuration file worked correctly in Linux automount version 4.1.3-187

if the comment is removed, automounting works.   If the comment is the start of
the line, it works.  this only started to fail after up2date was ran, which
updated autofs (among others)

Version-Release number of selected component (if applicable):
Linux automount version 4.1.3-199.3

How reproducible:

Steps to Reproduce:
1. add a comment after a configuration line in automount like the example above
2. service autofs restart
3. cd /apps/pb
Actual results:
cd: /apps/pb/: No such file or directory

Expected results:
automount /apps/pb, pwd should change to /apps/pb

Additional info:
Would hope this regression could be corrected, as we have a number of custom
packages which have comments added after an addition to /etc/auto_apps which
worked prior to updating autofs

I've reproduced the problem and I'll work on a fix.  Thanks for the bug report.
Comment 2 Jeff Moyer 2007-10-09 12:19:00 EDT
In version 4.1.3-187, the mount_nfs module would perform its own parsing on the
mount string.  It treated every entry as a potential replicated server entry,
and sanitized strings accordingly (removing the comments).  In version
4.1.3-199, we moved to the replicated server selection code from autofs v5, and
this is the source of the regression.

The proper place to implement this checking, however, is in the sun parser
module.  I'll attach a patch shortly which corrects this problem in the parser.

This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.
Comment 6 Jeff Moyer 2008-01-02 14:33:11 EST
A fix for this issue was built into autofs version 4.1.3-131.1.
