Willy, Thomas
This is v3 to allow run with minimal kernel config, see v2 [1].
Applied further suggestions from Thomas, It is based on our previous v5 sysret helper series [2] and Thomas' chmod_net removal patchset [3].
Now, a test report on arm/vexpress-a9 without procfs, shmem, tmpfs, net and memfd_create looks like:
LOG: testing report for arm/vexpress-a9:
14 chmod_self [SKIPPED] 16 chown_self [SKIPPED] 40 link_cross [SKIPPED] 0 -fstackprotector not supported [SKIPPED]
139 test(s) passed, 4 skipped, 0 failed. See all results in /labs/linux-lab/logging/nolibc/arm-vexpress-a9-nolibc-test.log
LOG: testing summary:

Changes from v2 --> v3:
* Added Reviewed-by from Thomas for the whole series, Many Thanks
* selftests/nolibc: stat_fault: silence NULL argument warning with glibc selftests/nolibc: gettid: restore for glibc and musl selftests/nolibc: add _LARGEFILE64_SOURCE for musl selftests/nolibc: fix up int_fast16/32_t test cases for musl selftests/nolibc: fix up kernel parameters support selftests/nolibc: stat_timestamps: remove procfs dependency selftests/nolibc: link_cross: use /proc/self/cmdline tools/nolibc: add rmdir() support selftests/nolibc: add a new rmdir() test case selftests/nolibc: fix up failures when CONFIG_PROC_FS=n selftests/nolibc: vfprintf: remove MEMFD_CREATE dependency
No code changes except some commit message cleanups.
* selftests/nolibc: prepare /tmp for tmpfs or ramfs
As suggested by Thomas, simply calling mkdir() and mount() to prepare /tmp can save a stat() call.
* selftests/nolibc: chroot_exe: remove procfs dependency
As suggested by Thomas, remove the 'weird' get_tmpfile() and use the '/init' for !procfs as we did for stat_timestamps.
For the worst-case scene, when '/init' is not there, add ENOENT to the error check list.
Now, it is a oneline code change.
* selftests/nolibc: add chmod_tmpdir test
Without get_tmpfile(), let's direct mkdir() a temp directory for chmod_tmpdir test, it function as a substitute for the removed chmod_net.
Now, it is a oneline code change.
