selftests: Fix test errors related to lib.mk khdr target

2019-01-13T08:24:09+00:00

commit 211929fd3f7c8de4d541b1cc243b82830e5ea1e8 upstream.

Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") added
khdr target to run headers_install target from the main Makefile. The
logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize
variables and include files to run headers_install from the top level
Makefile. There are a few problems with this logic.

1. Exposes top_srcdir to all tests
2. Common logic impacts all tests
3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests
   add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in
   some cases, and STATIC_LIBS in other cases. This makes this framework
   confusing to use.

The common logic that runs for all tests even when KSFT_KHDR_INSTALL
isn't defined by the test. top_srcdir is initialized to a default value
when test doesn't initialize it. It works for all tests without a sub-dir
structure and tests with sub-dir structure fail to build.

e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf

../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory
make: *** No rule to make target '../../../../scripts/subarch.include'.  Stop.

There is no reason to require all tests to define top_srcdir and there is
no need to require tests to add khdr dependency using adhoc changes to
TEST_* and other variables.

Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests
that have the dependency on headers_install.

Change common logic to include khdr target define and "all" target with
dependency on khdr when KSFT_KHDR_INSTALL is defined.

Only tests that have dependency on headers_install have to define just
the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to
specify khdr dependency in the test Makefiles.

tc-testing: tdc.py: Guard against lack of returncode in executed command

2018-11-18T05:54:53+00:00

Add some defensive coding in case one of the subprocesses created by tdc
returns nothing. If no object is returned from exec_cmd, then tdc will
halt with an unhandled exception.

tc-testing: tdc.py: ignore errors when decoding stdout/stderr

2018-11-18T05:54:53+00:00

Prevent exceptions from being raised while decoding output

execution and the verify command phase would fail the pattern

tc-testing: use a plugin to build eBPF program

2018-10-05T21:44:56+00:00

use a TDC plugin, instead of building eBPF programs in the 'setup' stage.
'-B' argument can be used to build eBPF programs in $EBPFDIR directory,
in the 'pre-suite' stage. Binaries are then cleaned in 'post-suite' stage.

tc-testing: add test-cases for numeric and invalid control action

2018-08-30T05:10:59+00:00

Only the police action allows us to specify an arbitrary numeric value
for the control action. This change introduces an explicit test case
for the above feature and then leverage it for testing the kernel behavior
for invalid control actions (reject).
