selftests: fixup build warnings in pidfd / clone3 tests

2022-02-04T20:07:07+00:00

These are some trivial fixups, which were needed to build the tests with
clang and -Werror. The following issues are fixed:

- Remove various unused variables.
- In child_poll_leader_exit_test, clang isn't smart enough to realize
  syscall(SYS_exit, 0) won't return, so it complains we never return
  from a non-void function. Add an extra exit(0) to appease it.
- In test_pidfd_poll_leader_exit, ret may be branched on despite being
  uninitialized, if we have !use_waitpid. Initialize it to zero to get
  the right behavior in that case.

selftests: clone3: clone3: add case CLONE3_ARGS_NO_TEST

2021-12-10T23:46:01+00:00

Building selftests/clone3 with clang warns about enumeration not handled
in switch case:

clone3.c:54:10: warning: enumeration value 'CLONE3_ARGS_NO_TEST' not handled in switch [-Wswitch]
        switch (test_mode) {
                ^

Add the missing switch case with a comment.

selftests/clone3: Fix build error

2020-12-07T21:34:55+00:00

When compiling the selftests with the -std=gnu99 option the build can
fail with.

Following build error:

  test_core.c: In function ‘test_cgcore_destroy’:
  test_core.c:87:2: error: ‘for’ loop initial declarations are only
  allowed in C99 mode
    for (int i = 0; i < 10; i++) {
    ^
  test_core.c:87:2: note: use option -std=c99 or -std=gnu99 to compile

Add -std=gnu99 to the clone3 selftest Makefile to fix this.

XFAIL is gone since commit 9847d24af95c ("selftests/harness: Refactor XFAIL

selftests/clone3: Avoid OS-defined clone_args

2020-10-08T20:17:25+00:00

As the UAPI headers start to appear in distros, we need to avoid
outdated versions of struct clone_args to be able to test modern
features, named "struct __clone_args". Additionally update the struct
size macro names to match UAPI names.

selftests: add clone3() CAP_CHECKPOINT_RESTORE test

2020-07-20T13:47:42+00:00

This adds a test that changes its UID, uses capabilities to
get CAP_CHECKPOINT_RESTORE and uses clone3() with set_tid to
create a process with a given PID as non-root.

Pull SPDX updates from Greg KH:
 "Here are three SPDX patches for 5.7-rc1.

  One fixes up the SPDX tag for a single driver, while the other two go
  through the tree and add SPDX tags for all of the .gitignore files as
  needed.

  Nothing too complex, but you will get a merge conflict with your
  current tree, that should be trivial to handle (one file modified by
  two things, one file deleted.)

  All three of these have been in linux-next for a while, with no
  reported issues other than the merge conflict"
