* perf test: Fix variable length array undefined behavior in bp_accountIan Rogers2022-06-191-2/+14
| | | | | | | | | | | | | | | | | | | Fix: tests/bp_account.c:154:9: runtime error: variable length array bound evaluates to non-positive value 0 by switching from a variable length to an allocated array.

* perf tests bp_account: Add dedicated checking helper is_supported()Leo Yan2019-10-191-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arm architecture supports breakpoint accounting but it doesn't support breakpoint overflow signal handling. The current code uses the same checking helper, thus it disables both testings (bp_account and bp_signal) for arm platform. For handling two testings separately, this patch adds a dedicated checking helper is_supported() for breakpoint accounting testing, thus it allows supporting breakpoint accounting testing on arm platform; the old helper test__bp_signal_is_supported() is only used to checking for breakpoint overflow signal testing.

* perf tests: Fix out of bounds access on array fd when cnt is 100Colin Ian King2018-03-161-5/+3
| | | | | | | | | | | | | | | | | | | | | | Currently when cnt is 100 an array bounds overflow occurs on the assignment of fd[cnt]. Fix this by performing the bounds check on cnt before writing to fd. Detected by cppcheck: tools/perf/tests/bp_account.c:115: (warning) Either the condition 'cnt==100' is redundant or the array 'fd[100]' is accessed at index 100, which is out of bounds.
