Vit Mojzis 48602370ac python: Harden tools against "rogue" modules
Python scripts present in "/usr/sbin" override regular modules.
Make sure /usr/sbin is not present in PYTHONPATH.

Fixes:
  #cat > /usr/sbin/audit.py <<EOF
  import sys
  print("BAD GUY!", file=sys.stderr)
  sys.exit(1)
  EOF
  #semanage boolean -l
  BAD GUY!

Vit Mojzis 344463076b gettext: handle unsupported languages properly
With "fallback=True" gettext.translation behaves the same as
gettext.install and uses NullTranslations in case the
translation file for given language was not found (as opposed to
throwing an exception).

Fixes:
  # LANG is set to any "unsupported" language, e.g. en_US.UTF-8
  $ chcat --help
  Traceback (most recent call last):
  File "/usr/bin/chcat", line 39, in <module>
    t = gettext.translation(PROGNAME,
  File "/usr/lib64/python3.9/gettext.py", line 592, in translation
    raise FileNotFoundError(ENOENT,
  FileNotFoundError: [Errno 2] No translation file found for domain: 'selinux-python'

Vit Mojzis b14d5de5b4 gettext: set _ on module level instead of builtins namespace
Some calls to "_" where unsuccessful because the function was
initialized with a different translation domain than the string.
e.g. selinux-polgengui calls functions from sepolicy.generate, which end
up printing untranslated strings because polgengui uses selinux-gui
domain while sepolicy uses selinux-python

- Set "_" in module namespace instead of "builtins"
- Set the whole "sepolicy.generate()" confirmation as translatable
- Drop "codeset" parameter since it is deprecated

Petr Lautrbach 2d668b6214 Split po/ translation files into the relevant sub-directories
When policycoreutils was split into policycoreutils/ python/ gui/ and sandbox/
sub-directories, po/ translation files stayed in policycoreutils/.

This commit splits original policycoreutils translations to
policycoreutils, selinux-python, selinux-gui, and selinux-sandbox.

python: always use python3 in the shebang of programs using setools
setools 4.2.0 dropped support for Python 2. On systems where
/usr/bin/python is Python 2, several tools are now broken because of
this. Update the shebang of these tools to /usr/bin/python3.

For future reference, as semanage/seobject.py, sepolicy and sepolgen
import setools, every program that uses one of these modules need to be
run with Python 3. The following programs do not use any of these
modules so their shebangs have not been modified:

    dbus/selinux_server.py
    libsemanage/utils/semanage_migrate_store
    mcstrans/share/util/mlscolor-test
    mcstrans/share/util/mlstrans-test
    sandbox/start

Nicolas Iooss f39c0ac637 python/chcat: fix removing categories on users with Fedora default setup
Using Vagrant with fedora/28-cloud-base image, SELinux logins are
configured this way:

    # semanage login -l
    Login Name           SELinux User         MLS/MCS Range        Service

    __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.

Fix this issue by splitting the list of categories before calling
expandCats().

Stephen Smalley 7b5699bfd7 Fix BINDIR/SBINDIR/... variables in Makefiles
As reported by Nicolas Iooss, there are still some inconsistencies
in the definitions and usage of Makefile variables related to bin
and sbin directories. Since we need to still support non-usrmerge
systems, we cannot completely synchronize them, but we can eliminate
unnecessary differences, remove unused variables, and drop the
USRSBINDIR variables.

Before:
$ find . -name Makefile -exec cat {} + |grep '^[A-Z_]*BINDIR' |sort -u
BINDIR=$(PREFIX)/bin
BINDIR ?= $(PREFIX)/bin
BINDIR ?= $(PREFIX)/sbin
SBINDIR ?= $(DESTDIR)/sbin
SBINDIR ?= $(PREFIX)/sbin
USRSBINDIR ?= $(PREFIX)/sbin

After:
$ find . -name Makefile -exec cat {} + | grep '^[A-Z_]*BINDIR' | sort -u
BINDIR ?= $(PREFIX)/bin
SBINDIR ?= $(DESTDIR)/sbin
SBINDIR ?= $(PREFIX)/sbin

This does not change the actual install location of any file.
It does drop the legacy symlink from /usr/sbin/load_policy to
/sbin/load_policy; packagers can create that separately if
desired.
