Willy, Thomas
This is v2 to allow run with minimal kernel config, see v1 [1].
It mainly applied the 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_net [SKIPPED]
15 chmod_self [SKIPPED]
17 chown_self [SKIPPED]
41 link_cross [SKIPPED]
0 -fstackprotector not supported [SKIPPED]
139 test(s) passed, 5 skipped, 0 failed.
See all results in /labs/linux-lab/logging/nolibc/arm-vexpress-a9-nolibc-test.log

arm/vexpress-a9 | 139 test(s) passed, 5 skipped, 0 failed. See all results in /labs/linux-lab/logging/nolibc/arm-vexpress-a9-nolibc-test.log
Changes from v1 --> v2:
* 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: add a new rmdir() test case
selftests/nolibc: fix up failures when CONFIG_PROC_FS=n
The same as v1, only a few of commit message changes.
* selftests/nolibc: fix up int_fast16/32_t test cases for musl
Applied the method suggested by Thomas, two new macros are added to
get SINT_MAX_OF_TYPE(type) and SINT_MIN_OF_TYPE(type).
* selftests/nolibc: fix up kernel parameters support
After discuss with Thomas and with more tests, both of argv[1] and
NOLIBC_TEST environment variable should be verified to support
such kernel parameters:
NOLIBC_TEST=syscall
noapic NOLIBC_TEST=syscall
noapic
* selftests/nolibc: stat_timestamps: remove procfs dependency
Add '/init' and '/' for !procfs, don't skip it.
* selftests/nolibc: link_cross: use /proc/self/cmdline
Use /proc/self/cmdline instead of /proc/self/net, the ramfs based
/tmp/file doesn't work as expected (not really crossdev).
* tools/nolibc: add rmdir() support
Now, rebased on __sysret() from sysret helper patchset [2].
* selftests/nolibc: prepare /tmp for tmpfs or ramfs
Removed the hugetlbfs prepare part, not really required.
Don't remove /tmp and reserve it to use ramfs as tmpfs.
* selftests/nolibc: add common get_tmpfile()
selftests/nolibc: rename chroot_exe to chroot_tmpfile
Some cleanups.
* selftests/nolibc: add chmod_tmpfile test
To avoid conflict with Thomas' chmod_net removal patch [3], a new
chmod_tmpfile is added (in v1, there is a rename patch from
chmod_net to chmod_good)
Still to avoid conflict, these two are removed in this series:
- selftests/nolibc: rename proc variable to has_proc
- selftests/nolibc: rename euid0 variable to is_root
* selftests/nolibc: vfprintf: remove MEMFD_CREATE dependency
Many checks are removed, only reserve the direct tmpfs access
version.
Best regards,
Zhangjin
