Description Tomasz Kepczynski 2007-05-02 19:57:37 UTC 
Description of problem:
I have two machines which complain as below when updating
selinux policy as below:
tk homedir /local/tk or its parent directory conflicts with a
defined context in /etc/selinux/targeted/contexts/files/file_contexts,
/usr/sbin/genhomedircon will not create a new context. This usually indicates an
incorrectly defined system account.  If it is a system account please make sure
its login shell is /sbin/nologin.

In the above example I traced the offending line in file_contexts to
be a line 495:
/usr/local/(.*/)?nprhapengine\.so.*     --      system_u:object_r:textrel_shlib_
This is the first line containing string "/local" in it.
My guess is that line 305 in genhomedircon in function
checkExists is incorrect. It reads:
if re.search(home, regex, 0):
while it should probably be:
if re.search(regex, home, 0):
(check http://docs.python.org/lib/node46.html for re.search
parameters).

Version-Release number of selected component (if applicable):
policycoreutils-1.34.1-8.fc6
selinux-policy-targeted-2.4.6-62.fc6

How reproducible:
Always by running genhomedircon

Actual results:
genhomedircon prints warning and seems to fail to properly
update file_contexts.homedirs.

Expected results:
No errors/warning and file_contexts.homedirs correctly updated.

Additional info:
Patch attached.

Actually this is reversed patch.
I also fix a typo in summary.
Comment 3 Daniel Walsh 2007-05-03 14:42:14 UTC 
THis is complaining because you have a user in your /etc/passwd with a homedir
of /local/tk.  Is this a real user?  If not it should have a login shell of
/bin/false.  And then genhomedircon will not complain.
Comment 4 Tomasz Kepczynski 2007-05-04 05:02:23 UTC 
Yes, this is real user.
On the other machine I have lots of real users in /user and have
the same problem.
I also mentioned a line which is matched in my bug report and
this is really something I wouldn't expect.
