This one doesn't work for me on x86_64 kernel 5.15.112, qemu userland: 46 mmap_bad = <0x0> EEXIST != (<0xffffffffffffffff> EINVAL) [FAIL] This EEXIST actually is the errno from the previous test. If I run the test natively it's OK: $ ./nolibc-test syscall:46 Running test 'syscall' 46 mmap_bad = <0xffffffffffffffff> EINVAL [OK] Errors during this test: 0 I'll queue it anyway for now but it would be nice that we figure what's happening (even if we need to adjust or drop the test if it's a false positive) so that we don't get used to "ah this is a normal error".
