What values do PKRU and the shadow have when the test fails? Is PKRU 0?
It goes back to default value 0x55555554. The test is expecting it to be 0. Printed them below.
test_ptrace_of_child()::1346, pkey_reg: 0x0000000055555554 shadow: 0000000000000000 protection_keys_64: pkey-helpers.h:127: _read_pkey_reg: Assertion `pkey_reg == shadow_pkey_reg' failed.
That's backwards (shadow vs pkru) from what I was expecting.
Can you turn on all the debuging?
Just compile with -DDEBUG_LEVEL=5
