2023-03-28selftests: prctl: Add new prctl test for PR_SET_VMA actionIvan Orlov5-1/+108
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. Signed-off-by: Ivan Orlov <[email protected]> Signed-off-by: Shuah Khan <[email protected]>

There are several 'malloc' calls in test_memcontrol, which can be unsuccessful.

For the cflags to enable stack protectors to work properly they need to be specified after -fno-stack-protector. To do this fold all cflags into a single variable and move -fno-stack-protector before the arch-specific cflags and another one specific to stack protectors since we don't want to enable them on all archs.
