selftests/net: correct the return value for run_netsocktests

2019-05-16T17:45:06+00:00

[ Upstream commit 30c04d796b693e22405c38e9b78e9a364e4c77e6 ]

The run_netsocktests will be marked as passed regardless the actual test
result from the ./socket:

    selftests: net: run_netsocktests
    ========================================
    --------------------
    running socket test
    --------------------
    [FAIL]
    ok 1..6 selftests: net: run_netsocktests [PASS]

This is because the test script itself has been successfully executed.
Fix this by exit 1 when the test failed.

selftests/net: fixes psock_fanout eBPF test case

2018-05-30T05:49:16+00:00

[ Upstream commit ddd0010392d9cbcb95b53d11b7cafc67b373ab56 ]

eBPF test fails due to verifier failure because log_buf is too small.
Fixed by increasing log_buf size

selftests: do not require bash to run netsocktests testcase

2017-01-19T19:17:18+00:00

commit 3659f98b5375d195f1870c3e508fe51e52206839 upstream.

Nothing in this minimal script seems to require bash. We often run these
tests on embedded devices where the only shell available is the busybox
ash. Use sh instead.

selftests/net: test extended BPF fanout mode

2015-08-17T21:22:48+00:00

Test PACKET_FANOUT_EBPF by inserting a program into the the kernel
with bpf(), then attaching it to the fanout group. Observe the same
payload-based distribution as in the PACKET_FANOUT_CBPF test.

selftests/net: test classic bpf fanout mode

2015-08-17T21:22:48+00:00

Test PACKET_FANOUT_CBPF by inserting a cBPF program that selects a
socket by payload. Requires modifying the test program to send
packets with multiple payloads.

Also fix a bug in testing the return value of mmap()

selftests/net: expect headroom in psock_fanout rollover

2015-05-18T21:04:18+00:00

psock_fanout tests the various fanout modes. Change the test for
rollover mode to expect early rollover due to socket pressure
as implemented in 2ccdbaa6d55b ("packet: rollover lock contention
avoidance").

selftests: Set CC using CROSS_COMPILE once in lib.mk

2015-03-19T21:16:51+00:00

This avoids repeating the logic in every Makefile. We mimic the
top-level Makefile and use $(CROSS_COMPILE)gcc.

selftests: Add install target

2015-03-13T21:21:56+00:00

This adds make install support to selftests. The basic usage is:

$ cd tools/testing/selftests
$ make install

That installs into tools/testing/selftests/install, which can then be
copied where ever necessary.

The install destination is also configurable using eg:

$ INSTALL_PATH=/mnt/selftests make install

The implementation uses two targets in the child makefiles. The first
"install" is expected to install all files into $(INSTALL_PATH).

The second, "emit_tests", is expected to emit the test instructions (ie.
bash script) on stdout. Separating this from install means the child
makefiles need no knowledge of the location of the test script.

selftests: Introduce minimal shared logic for running tests

2015-03-13T21:13:40+00:00

This adds a Make include file which most selftests can then include to
get the run_tests logic.

On its own this has the advantage of some reduction in repetition, and
also means the pass/fail message is defined in fewer places.

However the key advantage is it will allow us to implement install very
simply in a subsequent patch.

The default implementation just executes each program in $(TEST_PROGS).

We use a variable to hold the default implementation of $(RUN_TESTS)
because that gives us a clean way to override it if necessary, ie. using
override. The mount, memory-hotplug and mqueue tests use that to provide
a different implementation.

Tests are not run via /bin/bash, so if they are scripts they must be
executable, we add a+x to several.

Pull kselftest update from Shuah Khan:
 "kselftest updates for 3.19-rc1:

   - kcmp test include file cleanup
   - kcmp change to build on all architectures
   - A light weight kselftest framework that provides a set of
     interfaces for tests to use to report results.  In addition,
     several tests are updated to use the framework.
   - A new runtime system size test that prints the amount of RAM that
     the currently running system is using"
