x86/selftests/pkeys: Fork() to check for state being preserved

2019-01-31T07:12:36+00:00

commit e1812933b17be7814f51b6c310c5d1ced7a9a5f5 upstream. There was a bug where the per-mm pkey state was not being preserved across fork() in the child. fork() is performed in the pkey selftests, but all of the pkey activity is performed in the parent. The child does not perform any actions sensitive to pkey state. To make the test more sensitive to these kinds of bugs, add a fork() where the parent exits, and execution continues in the child. To achieve this let the key exhaustion test not terminate at the first allocation failure and fork after 2*NR_PKEYS loops and continue in the child.

selftests: add script to stress-test nft packet path vs. control plane

2018-12-17T08:38:32+00:00

[ Upstream commit 25d8bcedbf4329895dbaf9dd67baa6f18dad918c ] Start flood ping for each cpu while loading/flushing rulesets to make sure we do not access already-free'd rules from nf_tables evaluation loop. Also add this to TARGETS so 'make run_tests' in selftest dir runs it automatically. This would have caught the bug fixed in previous change ("netfilter: nf_tables: do not skip inactive chains during generation update") sooner.

powerpc/selftests: Wait all threads to join

2018-11-21T08:25:57+00:00

[ Upstream commit 693b31b2fc1636f0aa7af53136d3b49f6ad9ff39 ] Test tm-tmspr might exit before all threads stop executing, because it just waits for the very last thread to join before proceeding/exiting. This patch makes sure that all threads that were created will join before proceeding/exiting. This patch also guarantees that the amount of threads being created is equal to thread_num.

selftest: timers: Tweak raw_skew to SKIP when ADJ_OFFSET/other clock adjustments are in progress

2018-09-26T06:36:39+00:00

[ Upstream commit 1416270f4a1ae83ea84156ceba19a66a8f88be1f ] In the past we've warned when ADJ_OFFSET was in progress, usually caused by ntpd or some other time adjusting daemon running in non steady sate, which can cause the skew calculations to be incorrect. Thus, this patch checks to see if the clock was being adjusted when we fail so that we don't cause false negatives.
