Dmitry Muhomor	f16ef601d4	memtag_test: improve capturing of test results Using debuggerd + logcat parsing is unreliable and slow, print SEGV signal code to stderr instead.	2023-10-30 14:20:53 -04:00
Dmitry Muhomor	155800526a	memtag_test: improve tag_distinctness test - check that tag distinctess checks are actually reached (it was previously verified manually by looking at the now-removed printf output) - check that only non-reserved tags are used - check that all of non-reserved tags are used - print tag usage statistics at the end of run	2023-10-30 14:20:53 -04:00
Dmitry Muhomor	28d5d394cf	memtag_test: remove usages of rand() It didn't work correctly due to not being seeded and its usage wasn't necessary.	2023-10-30 14:20:53 -04:00
Dmitry Muhomor	576328b1b4	android: add MTE tests To run them, connect an MTE-enabled device via adb and execute `atest HMallocTest:MemtagTest`. Since these tests are not deterministic (and neither is hardened_malloc itself), it's better to run them multiple times, e.g. `atest --iterations 30 HMallocTest:MemtagTest`. There are also CTS tests that are useful for checking correctness of the Android integration: `atest CtsTaggingHostTestCases`	2023-10-30 14:20:53 -04:00
