selftests/futex: Convert 32-bit timespec to 64-bit version for 32-bit compatibility mode

2025-07-06T09:15:29Z

sys_futex_wait() expects a struct __kernel_timespec pointer for the timeout, but the provided struct timespec pointer is of type struct old_timespec32 when compiled for 32-bit architectures, unless they use 64-bit timespecs already. Make it work for all variants by converting the provided timespec value into a local struct __kernel_timespec and provide a pointer to it to the syscall. This is a pointless operation for 64-bit, but this is not a hotpath operation, so keep it simple.

selftests/futex: Add futex_numa_mpol

2025-05-03T10:02:10Z

Test the basic functionality for the NUMA and MPOL flags: - FUTEX2_NUMA should take the NUMA node which is after the uaddr and use it. - Only update the node if FUTEX_NO_NODE was set by the user - FUTEX2_MPOL should use the memory based on the policy. I attempted to set the node with mbind() and then use this with MPOL but this fails and futex falls back to the default node for the current CPU.

selftests: futex: Add sys_futex_waitv() test

2021-10-07T11:51:12Z

Create a new file to test the waitv mechanism. Test both private and shared futexes. Wake the last futex in the array, and check if the return value from futex_waitv() is the right index.
