Description Moray.Henderson 2012-06-06 14:58:12 UTC
Description of problem:
Loading a custom SELinux policy module which worked on RHEL 5 gives unhelpful error in RHEL 6.  The actual cause was conflict with a file context rule new to RHEL 6.

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

How reproducible:

Steps to Reproduce:
1.  Create new policy module with file context pattern that already exists in standard policy (e.g. /var/run/passenger(/.*)? )
2.  Try to load it.

Actual results:
# semodule -i mypolicy.pp
/etc/selinux/targeted/contexts/files/file_contexts: Invalid argument
libsemanage.semanage_install_active: setfiles returned error code 1. 
semodule:  Failed!

Expected results:
# semodule -i mypolicy.pp
File context already exists for /var/run/passenger: mypolicy.fc line 5
semodule:  Failed!

or similar message.

Additional info:
There is a reasonable error message in the Fedora 17 version:

# semodule -i mypol.pp
/etc/selinux/targeted/contexts/files/file_contexts: Multiple different specifications for /var/run/passenger(/.*)?
(system_u:object_r:passenger_var_run_t:s0 and system_u:object_r:var_run_t:s0).
/etc/selinux/targeted/contexts/files/file_contexts: Invalid argument
libsemanage.semanage_install_active: setfiles returned error code 1.
semodule:  Failed!

Would be nice to include the line number of mypol.fc which caused the error, but at least the Fedora 17 version of the message should be released into RHEL 6.2.
