one of the test status: success, warning and failure is printed to
summarize the passed, skipped and failed values.
- "success" means no skipped and no failed.
- "warning" means has at least one skipped and no failed.
- "failure" means all tests are failed.

'/proc/self/' is a good path which doesn't have stale time info but it
is only available for CONFIG_PROC_FS=y.
When CONFIG_PROC_FS=n, use argv0 instead of '/proc/self', use '/' for the
worst case.

The PWD environment variable has the path of the nolibc-test program,
the current path must be the same as it, otherwise, the test cases will
fail with relative path (e.g. ./nolibc-test).
Since only chdir_root really changes the current path, let's restore it
with the PWD environment variable.

The vfprintf test case require to open a temporary file to write, the
old memfd_create() method is perfect but has strong dependency on
MEMFD_CREATE and also TMPFS or HUGETLBFS (see fs/Kconfig):
config MEMFD_CREATE
def_bool TMPFS || HUGETLBFS
And from v6.2, MFD_NOEXEC_SEAL must be passed for the non-executable
memfd, otherwise, The kernel warning will be output to the test result
like this:
Running test 'vfprintf'
0 emptymemfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL, pid=1 'init'
"" = "" [OK]
To avoid such warning and also to remove the MEMFD_CREATE dependency,
let's open a file from tmpfs directly.
The /tmp directory is used to detect the existing of tmpfs, if not
there, skip instead of fail.
And further, for pid == 1, the initramfs is loaded as ramfs, which can
be used as tmpfs, so, it is able to further remove TMPFS dependency too.

[wt: removed the unneeded mount() call]
Signed-off-by: Willy Tarreau <[email protected]>
|

For CONFIG_PROC_FS=n, the /proc is not mountable, but the /proc
directory has been created in the prepare() stage whenever /proc is
there or not.
so, the checking of /proc in the run_syscall() stage will be always true
and at last it will fail all of the procfs dependent test cases, which
deviates from the 'cond' check design of the EXPECT_xx macros, without
procfs, these test cases should be skipped instead of failed.
To solve this issue, one method is checking /proc/self instead of /proc,
another method is removing the /proc directory completely for
CONFIG_PROC_FS=n, we apply the second method to avoid misleading the
users.

kernel parameters allow pass two types of strings, one type is like
'noapic', another type is like 'panic=5', the first type is passed as
arguments of the init program, the second type is passed as environment
variables of the init program.
when users pass kernel parameters like this:
noapic NOLIBC_TEST=syscall
our nolibc-test program will use the test setting from argv[1] and
ignore the one from NOLIBC_TEST environment variable, and at last, it
will print the following line and ignore the whole test setting.
Ignoring unknown test name 'noapic'
reversing the parsing order does solve the above issue:
test = getenv("NOLIBC_TEST");
if (test)
test = argv[1];
but it still doesn't work with such kernel parameters (without
NOLIBC_TEST environment variable):
noapic FOO=bar
To support all of the potential kernel parameters, let's verify the test
setting from both of argv[1] and NOLIBC_TEST environment variable.

mmap() a file with a good offset and then munmap() it. a non-zero offset
is passed to test the 6th argument of my_syscall6().
Note, it is not easy to find a unique file for mmap() in different
scenes, so, a file list is used to search the right one:
- /dev/zero: is commonly used to allocate anonymous memory and is likely
present and readable
- /proc/1/exe: for 'run' and 'run-user' target, 'run-user' can not find
'/proc/self/exe'
- /proc/self/exe: for 'libc-test' target, normal program 'libc-test' has
no permission to access '/proc/1/exe'
- argv0: the path of the program itself, let it pass even with worst
case scene: no procfs and no /dev/zero

Before adding a port to bond, it need to be set down first. In the
lacpdu test the author set the port down specifically. But commit
a4abfa627c38 ("net: rtnetlink: Enslave device before bringing it up")
changed the operation order, the kernel will set the port down _after_
adding to bond. So all the ports will be down at last and the test failed.
In fact, the veth interfaces are already inactive when added. This
means there's no need to set them down again before adding to the bond.
Let's just remove the link down operation.

use case, so instead look at KSM stats.
Trigger a complete unmerge first, to cleanup the stable tree and
stabilize accounting of merged pages.
Note that we're using /proc/self/ksm_merging_pages instead of
/proc/self/ksm_stat, because that one is available in more existing
kernels.
If /proc/self/ksm_merging_pages can't be opened, we can't perform any
checks and simply skip them.
We have to special-case the shared zeropage for now. But the only user
-- test_unmerge_zero_pages() -- performs its own merge checks.

There is only one Kconfig user of CONFIG_EMBEDDED and it can be switched
to EXPERT or "if !ARCH_MULTIPLATFORM" (suggested by Arnd).

Extract from current /proc/self/smaps output:
Swap: 0 kB
SwapPss: 0 kB
Locked: 0 kB
THPeligible: 0
ProtectionKey: 0
That's not the alignment shown in Documentation/filesystems/proc.rst: it's
an ugly artifact from missing out the %8 other fields are using; but
there's even one selftest which expects it to look that way. Hoping no
other smaps parsers depend on THPeligible to look so ugly, fix these.

This adds proper tests for the nesting functionality of vm.memfd_noexec as
well as some minor cleanups to spawn_*_thread().
