[PATCH] Refactor 'peeksiginfo' ptrace test part

by Ivan Orlov

peeksiginfo creates an array of 10 instances of 'siginfo_t', but actually uses only one. This patch will reduce amount of memory on the stack used by the peeksiginfo test.

[PATCH] selftests: cgroup: Add 'malloc' failures checks in test_memcontrol

by Ivan Orlov

There are several 'malloc' calls in test_memcontrol, which can be unsuccessful. This patch will add 'malloc' failures checking to give more details about test's fail reasons and avoid possible undefined behavior during the future null dereference (like the one in alloc_anon_50M_check_swap function).

[PATCH v2] selftests: prctl: Add new prctl test for PR_SET_VMA action

by Ivan Orlov

This patch will add the new test, which covers the prctl call with PR_SET_VMA command. The test tries to give a name to the anonymous VMA within the process memory map, and then checks the result of the operation by parsing 'maps' virtual file. Additionally, the test tries to call the prctl PR_SET_VMA command with invalid arguments, and checks the error codes for correctness. At the moment anonymous VMA naming through prctl call functionality is not covered with any tests, so I think implementing it makes sense. In version 2 of this patch I consider the selftest Makefile rule about TARGETS entries order - I moved the 'prctl' entry in the Makefile to follow the lexicographic order. In version 1 it was placed at the end of the list.

new kunit infrastructure

by Johannes Berg

Hi all, Is there an established process for new kunit infrastructure? For example, we have this macro that makes KUNIT_ARRAY_PARAM easier by letting you just declare an array of test cases: /* Similar to KUNIT_ARRAY_PARAM, but avoiding an extra function */ #define KUNIT_ARRAY_PARAM_DESC(name, array, desc_member) \ static const void *name##_gen_params(const void *prev, char *desc) \ { \ typeof((array)[0]) *__next = prev ? ((typeof(__next)) prev) + 1 : (array); \ if (__next - (array) < ARRAY_SIZE((array))) { \ strscpy(desc, __next->desc_member, KUNIT_PARAM_DESC_SIZE); \ return __next; \ } \ return NULL; \ } Also, since we're working on wifi and thus networking, we want e.g. SKBs to be resource-managed, and added some helper macros/functions for using kunit_alloc_resource() with SKBs, that will be used at least in cfg80211 and mac80211 soon, so it would seem appropriate to have include/kunit/skb.h (and a corresponding C file somewhere) with these helpers. Is all of this just a case of "nobody needed it so far", or is there no expectation to add such infrastructure more generally? johannes

[PATCH] selftests/ftrace: Improve integration with kselftest runner

by Mark Brown

The ftrace selftests do not currently produce KTAP output, they produce a custom format much nicer for human consumption. This means that when run in automated test systems we just get a single result for the suite as a whole rather than recording results for individual test cases, making it harder to look at the test data and masking things like inappropriate skips. Address this by adding support for KTAP output to the ftracetest script and providing a trivial wrapper which will be invoked by the kselftest runner to generate output in this format by default, users using ftracetest directly will continue to get the existing output. This is not the most elegant solution but it is simple and effective. I did consider implementing this by post processing the existing output format but that felt more complex and likely to result in all output being lost if something goes seriously wrong during the run which would not be helpful. I did also consider just writing a separate runner script but there's enough going on with things like the signal handling for that to seem like it would be duplicating too much.
