Description Amadeusz Sławiński 2013-11-20 19:33:27 UTC
It doesn't work even in permissive:

# semanage fcontext -a -t swapfile_t "/swapfile"
libsepol.context_from_record: MLS is disabled, but MLS context "s0" found (No such file or directory).
libsepol.context_from_record: could not create context structure (Invalid argument).
libsemanage.validate_handler: invalid context system_u:object_r:swapfile_t:s0 specified for /swapfile [all files] (Invalid argument).
libsemanage.dbase_llist_iterate: could not iterate over records (Invalid argument).
OSError: Invalid argument

# semanage login -a -s staff_u amade            
libsemanage.validate_handler: MLS is disabled, but MLS range s0 was found for Unix user amade (No such file or directory).
libsemanage.validate_handler: seuser mapping [amade -> (staff_u, s0)] is invalid (No such file or directory).
libsemanage.dbase_llist_iterate: could not iterate over records (No such file or directory).
OSError: No such file or directory



Reproducible: Always

Comment 1 Amadeusz Sławiński 2013-12-05 18:47:17 UTC
http://thread.gmane.org/gmane.comp.security.selinux/19916
So after reversing patch in above link it still breaks

After looking some more into this it seems that if I use semanage from before following commit it works ok (with patch from mailing list applied)

http://userspace.selinuxproject.org/trac/changeset/c1f763e2933cc6bd4e89e7bbd603ae1de08d081c

no patches = breakage
patch from ml = breakage
semanage from before commit = breakage
patch from ml with semanage from before commit = works
Comment 2 Amadeusz Sławiński 2013-12-05 18:55:27 UTC
From new semanage code:

    parser.add_argument('-L', '--level', default='s0', help=_('Default SELinux Level for SELinux user, s0 Default. (MLS/MCS Systems only)'))
def parser_add_range(parser, name):                                             
    parser.add_argument('-r', '--range', default="s0",                            
                             help=_('''         

Seems like setting those defaults is wrong idea. It should probably check if it can do mls before setting it.
If I change them to default='' it works ok.
Comment 3 Sven Vermeulen (RETIRED) gentoo-dev 2013-12-10 15:06:41 UTC
policycoreutils 2.2.5 is now in the tree, can you check if everything works as expected now? I did a few tests here (strict policy) and it seems to work now.
Comment 4 Amadeusz Sławiński 2013-12-11 19:25:35 UTC
I've run few commands and it seems working ok.
Comment 5 Sven Vermeulen (RETIRED) gentoo-dev 2014-01-20 20:18:32 UTC
