----- Original Message -----

Hello,

We ran automated tests on a recent commit from this kernel tree:

   Kernel repo:
   git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux-stable.git
        Commit: d6c2c23a29f4 - Merge branch 'stable-next' of
        ssh://chubbybox:/home/sasha/data/next into stable-next

The results of these automated tests are provided below.

Overall result: FAILED (see details below)
         Merge: OK
       Compile: OK
         Tests: FAILED

All kernel binaries, config files, and logs are available for download here:

One or more kernel tests failed:

aarch64:
  ❌ LTP: openposix test suite

Test [1] is passing value close to LONG_MAX, which on arm64 is now treated as tagged userspace ptr: 057d3389108e ("mm: untag user pointers passed to memory syscalls")

And now seems to hit overflow check after sign extension (EINVAL). Test should probably find different way to choose invalid pointer.
