Subject: Some missing man pages from libselinux
Date: Wed, 24 Sep 2008 08:57:44 -0400
We are still missing the following man pages.
Perhaps some of these functions should be removed?
selinux_users_path seems to return a bogus directory?
Also do not have _raw functions defined in man pages.
matchpathcon_checkmatches
matchpathcon_filespec_add
matchpathcon_filespec_destroy
matchpathcon_filespec_eval
matchpathcon_index
matchpathcon_init_prefix
print_access_vector
security_canonicalize_context
security_disable
security_set_boolean_list
selinux_check_passwd_access
selinux_customizable_types_path
selinux_file_context_cmp
selinux_file_context_verify
selinux_get_callback
selinux_init_load_policy
selinux_lsetfilecon_default
selinux_mkload_policy
selinux_raw_to_trans_context
selinux_trans_to_raw_context
selinux_translations_path

Ok I found some problems with the previous patch and did some code
reuse. I added a function that only read base.pp in order to handle the
base user_extra and seusers problem.

Subject: Add glob support for restorecond
Date: Mon, 08 Sep 2008 15:03:51 -0400
-----BEGIN PGP SIGNED MESSAGE-----

I have added supported for GLOB expressions in restorecond. In order to
get nsplugin to work well, you need all of the contents of the homedir
labeled correctly. Unfortunately gnome creates directories at a fairly
random pace. FCFS. So it is very difficult to get transitions to
happen properly. As a tradeoff, we can use restorecond to watch the
homedir and relabel the directory when it is created. I know this is a
potential race condition. where some of the files created in the
directory will still have the wrong context, but I don't know of a
better solution.
Telling everyone they need to restorcon -R -v ~ is not a great solution.
If you are worried about information flow you should never rely on
restorecond.

Currently audit2allow/sepolgen will create two identical gen_requires
block if you have allow rules and a role statement.
This patch fixes this problem.

Sorry, it took some time. The revised patch for nodecon support in
the semanage tool is attached.
It now takes strings as arguments for the ip protocol. list/locallist
work as expected and output is more readable. I also made changes for
the semanage.8 man page.
Kind Regards,
Christian

This is the same off-by-one bug that was already fixed in the kernel.
(According to my understanding neither of these bugs has security
implications)
