[LTP] [ltp v2 0/4] futex: Add error coverage tests for wait, wake and cmp_requeue

[LTP] [ltp v2 0/4] futex: Add error coverage tests for wait, wake and cmp_requeue

[Michael Menasherov via ltp]

Improve error handling coverage for futex syscalls by adding tests
for missing error conditions that were previously untested.

futex_wait06 verifies EFAULT is returned when uaddr or timeout
points to unmapped memory.

futex_wait07 verifies EINTR is returned when futex_wait() is
interrupted by a signal.

futex_wake05 verifies EFAULT is returned when uaddr points to
unmapped or PROT_NONE memory.

futex_cmp_requeue03 verifies EFAULT is returned when uaddr or
uaddr2 points to unmapped memory, and EACCES or EFAULT when uaddr
points to memory without read permission (PROT_NONE). The EACCES
behavior was introduced in kernel 5.9.

v2:
 - Rebased on latest master
 - Added [ltp] subject prefix
 - Split into one patch per test case

Michael Menasherov (4):
  futex_wait06: Add EFAULT error coverage test
  futex_wait07: Add EINTR error coverage test
  futex_wake05: Add EFAULT error coverage test
  futex_cmp_requeue03: Add EFAULT and EACCES error coverage test

Re: [LTP] futex_wait06: Add EFAULT error coverage test

[linuxtestproject.agent]

Hi Michael,

All four patches are missing a commit body and Signed-off-by tag.
Please add at least one sentence explaining why each test is being added
(gap in coverage, related kernel change, regression, etc.), and add
your Signed-off-by trailer to each commit.

--- [PATCH 4/4] ---

I cannot find a kernel code path that returns -EACCES for a PROT_NONE
futex address. get_futex_key() in kernel/futex/core.c returns -EFAULT
when get_user_pages_fast() fails on an inaccessible page, regardless of
whether the failure is due to unmapped or PROT_NONE memory. Please cite
the specific kernel commit that introduced this behaviour, or replace the
conditional with unconditional EFAULT.

  Hi,

  Just a kind reminder about this patch series sent on May 7th.
  The LTP AI Reviewer has already approved all four patches.

  Would appreciate it if someone could take a look when time permits.

  Thanks,
