While using Ansible's Selinux module to manage ports, I discovered
that numerical ports caused an unhandled exception in 'seobject.py'.
This appears to be a bug, and I am proposing a fix which checks the

original functionality in the case of a string, and acts in the same
fashion if you supply an integer.

audit2allow testsuite requires a system which uses SELinux with a MLS
policy. This is a lot to ask for a continuous integretation system.
Thankfully this can be worked around by using option -p to run the tools
with a specific configuration. Doing this, the testsuite can even be run
on a system without SELinux.
This approach requires building a custom policy for parsing test.log.
Add a minimal policy written in CIL for this need.
While at it:
* Do not invoke "sudo sepolgen-ifgen" but produce a file in a writable
directory (instead of /var/lib/sepolgen/interface_info)
* Use sys.executable instead of 'python', in order to really test
python3 and python2 when calling the test script with one of these

Using Vagrant with fedora/28-cloud-base image, SELinux logins are
configured this way:
# semanage login -l

__default__ unconfined_u s0-s0:c0.c1023 *
root unconfined_u s0-s0:c0.c1023 *
vagrant unconfined_u s0-s0:c0.c1023 *
Using "chcat -l +c42 vagrant" successfully adds the category to user
vagrant, but "chcat -l -- -c42 vagrant" fails to remove it.
semanage login -l returns:
vagrant unconfined_u s0-s0:c0.c1023,c42 *
This issue is caused by expandCats(), which refuses to return a list of
more than 25 categories. This causes chcat_user_remove() to work with
cats=['c0.c1023,c42'] instead of cats=['c0.c102','c42'], which leads to
it not been able to remove 'c42' from the list.

Both "semanage user --help" and "man 8 semanage-user" state that
"semanage user" accepts option -s, but this is incorrect: -s is not
needed to specify the SELinux user on the command line, contrary to
"semanage login" for example. Fix the documention.
While at it, remove many spaces from the helptext of option --roles. I
do not know where they came from, but they were reduced to a single
space when displayed anyway.

Python does not need to end a statement with a semicolon. Doing this
gets reported by linters such as flake8 ("E703 statement ends with a
semicolon").
Remove such semicolons in the code and enable this warning in

av_extract_params() may call __param_insert() with only 2 parameters
instead of 4, which has no chance to work fine. Moreover it uses "PERM",
which is undefined. As nobody complained about this code, it seems to be
dead, so remove it.

sepolgen uses "return NotImplemented" (in access.py and matching.py) in
order to make Python's sorting function use an other call to compare
objects. For this to work, "NotImplemented" needs to be returned, not
raised like _compare's default implementation does.

"except OSError, ImportError:" does not perform what it says: it is the
Python 2 syntax of catching OSError exceptions as "ImportError" (like
"except OSError, e:"), and this is indeed caught by Python3:
File "./python/semanage/seobject.py", line 143
except OSError, ImportError:

The correct syntax consists in using parentheses.

semanage_seuser_modify_local and semanage_seuser_del_local already do
the logging.
Moreover, semanage log for loginRecords.__add was flawed since it
reported old-{seuser,role,range} of default user instead of None. This
was caused by selinux.getseuserbyname, which returns values for default
user when the specified username is not found.

Add support for extended permissions to audit2allow. Extend AuditParser
to parse the 'ioctlcmd' field in AVC message. Extend PolicyGenerator to
generate allowxperm rules. Add the '-x'/'--xperms' option to audit2allow
to turn on generating of extended permission AV rules.
AVCMessage parses the ioctlcmd field in AVC messages. AuditParser
converts the ioctlcmd values into generic representation of extended
permissions that is stored in access vectors.
Extended permissions are represented by operations (currently only
'ioctl') and values associated to the operations. Values (for example
'~{ 0x42 1234 23-34 }') are stored in the XpermSet class.
PolicyGenerator contains new method to turn on generating of xperms.
When turned on, for each access vector, standard AV rule and possibly
several xperm AV rules are generated. Xperm AV rules are represented by
the AVExtRule class.
With xperm generating turned off, PolicyGenerator provides comments
about extended permissions in certain situations. When the AVC message
contains the ioctlcmd field and the access would be allowed according to
the policy, PolicyGenerator warns about xperm rules being the possible
cause of the denial.
