git log -1 may use a pager to output long messages, and when the pager
is invoked, leads to stalls on the ci system waiting for user input.
Use --oneline to print the short part of the commit message and
the digest. This information is for debug/informational purposes only,
so truncating the output is sufficient.

Not everyone's github project is "selinux" so use the projects
name, as derived from TRAVIS_BUILD_DIR. TRAVIS_BUILD_DIR is
the absolute path to the project checkout on disk, so the
basename should be sufficient. The script that runs in the KVM
environment also needs to be updated where it can find the
selinux project code, so we pass it in through an env variable
in the ssh command.

The current Travis CI runs the userspace tooling and libraries against
policy files, but cannot test against an SELinux enabled kernel. Thus,
some tests are not being done in the CI. Travis, unfortunately only
provides Ubuntu images, so in order to run against a modern distro with
SELinux in enforcing mode, we need to launch a KVM with something like
Fedora.
This patch enables this support by launching a Fedora32 Cloud Image with
the SELinux userspace library passed on from the Travis clone, it then
builds and replaces the current SELinux bits on the Fedora32 image and
runs the SELinux testsuite.
The cloud image run can be controlled with the TRAVIS env variable:
TRAVIS_CLOUD_IMAGE_VERSION. That variable takes the major and minor
version numbers in a colon delimited string, eg: "32:1.6".

When a branch has '.py' suffix git creates a file with the same suffix and this
file is found by the `find . -name '*.py'` command. Such files from './git' need

On systems using non-default `PREFIX`, `LIBDIR`, `SHLIBDIR`, `BINDIR`
or `SBINDIR`, running
`DESTDIR=/path/to/destdir ./scripts/env_use_destdir make test`
does not perform the intended behavior, because the testing programs and
libraries are installed into locations that are not added to
`LD_LIBRARY_PATH` nor `PATH`.
More precisely, with `LIBDIR=/usr/lib64 SHLIBDIR=/lib64`, `env_use_destdir`
does not work. Fix this by adding the installation directories relative
to `DESTDIR` in `LD_LIBRARY_PATH` and `PATH`.

libselinux and libsemanage use:
PYTHONLIBDIR ?= $(shell $(PYTHON) -c "from distutils.sysconfig
import *; print(get_python_lib(plat_specific=1,
prefix='$(PREFIX)'))")
while python/semanage and python/sepolgen/src/sepolgen use:
PYTHONLIBDIR ?= $(shell $(PYTHON) -c "from distutils.sysconfig
import *; print(get_python_lib(prefix='$(PREFIX)'))")
This is right: libselinux and libsemanage's Python bindings use native
code (thus "plat_specific=1") while the others only install Python
files.
Nevertheless `scripts/env_use_destdir` only runs the second command
when computing `$PYTHONPATH`. When using this script to run `make test`
in a minimal Fedora 31 environment, this leads to an error such as:
make[2]: Entering directory '/code/python/sepolicy'
Traceback (most recent call last):
File "test_sepolicy.py", line 117, in <module>
import selinux
ModuleNotFoundError: No module named 'selinux'
Fix this by also adding `get_python_lib(plat_specific=1)` to the
computed `$PYTHONPATH`.
While at it, preserve `$PYTHONPATH` instead of resetting it. This makes
it easier to work with Python virtual environments.

Several static analyzers (clang's one, Facebook Infer, etc.) warn about
NULL pointer dereferences after a call to CU_ASSERT_PTR_NOT_NULL_FATAL()
in the test code written using CUnit framework. This is because this
CUnit macro is too complex for them to understand that the pointer
cannot be NULL: it is translated to a call to CU_assertImplementation()
with an argument as TRUE in order to mean that the call is fatal if the
asserted condition failed (cf.
http://cunit.sourceforge.net/doxdocs/group__Framework.html).
A possible solution could consist in replacing the
CU_ASSERT_..._FATAL() calls by assert() ones, as most static analyzers
know about assert(). Nevertheless this seems to go against CUnit's API.
An alternative solution consists in overriding CU_ASSERT_..._FATAL()
macros in order to expand to assert() after a call to the matching
CU_ASSERT_...() non-fatal macro. This appears to work fine and to remove
many false-positive warnings from various static analyzers.
As this substitution should only occur when using static analyzer, put
it under #ifdef __CHECKER__, which is the macro used by sparse when
analyzing the Linux kernel.

When running flake8 on a directory, it does not analyze files without an
extension, like semanage_migrate_store, mlscolor-test, etc. Use grep to
find files with a Python shebang and build a list which is then given to
flake8.
This commit is possible now that some clean-up patches have been
applied, such as commit 69c56bd2f6 ("python/chcat: improve the code
readability") and b7227aaec1 ("mcstrans: fix Python linter warnings on

Python does not need to end a statement with a semicolon. Doing this

flake8 is a Python linter which is able to detect issues in Python code
(syntax errors, undefined variables, etc.). It has been used to find
bugs in the project. In order to prevent the introduction of new bugs
which can be detected by it, add a script which runs it and use it in
Travis-CI.
flake8 can be used to detect code which is not written according to PEP8
style guide (which forbids whitespaces in some places, enforces the use
of space-indenting, specifies how many blank lines are used between
functions, etc.). As SELinux code does not follow this style guide,
scripts/run-flake8 disables many warnings related to this when running
the linter.
In order to silence flake8 warnings, the Python code can also be
modified. However fixing every "do not use bare 'except'" in the project
needs to be done carefully and takes much time.
This is why the warnings which are disabled have been ordered in three
lists:
* The warnings which can be activated in a not-so-distant future after
the code has been modified.
* The warnings related to PEP8 which cannot be activated without a major
cleaning work of the codebase (for example to modify white spaces)
* The warnings which are introduced by code generated by SWIG 3.0.12,
which would require patches in SWIG in order to be activated (there
is right now only one such warning).

Using clang's static analyzer is as simple as running "scan-build make",
but in order to obtain clean and reproducible results, the build
environment has to be cleaned beforehand ("make clean distclean").
Moreover the project requires running "make install" before "make test"
in order to install the dependencies needed for the tests, and running
these tests with the newly-built libraries requires a specific
LD_LIBRARY_PATH. This new script takes care of setting up everything
which is needed.
