[Devel] [PATCH hci-8.1 1/2] selftests/futex: run futex_waitv argument checks with a valid waitv

[no-reply at sashiko.virtuozzo.com]

> The argument checks reuse the waitv[] the shared subtest leaves behind,
> whose entries point into detached memory, and the invalid clockid
> check passes NULL waiters. So the kernel can reject a call for a
> reason other than the one tested. This goes unnoticed while the checks
> accept any result.
> 
> Reset waitv[] to valid private futexes before the checks and pass it to
> the clockid check.

> Fixes: 5e59c1d1c78c ("selftests: futex: Add sys_futex_waitv() test")
> https://virtuozzo.atlassian.net/browse/VSTOR-152660
