selftests/mm: add memory failure anonymous page test
Patch series "selftests/mm: add memory failure selftests", v4.
Introduce selftests to validate the functionality of memory failure. These tests help ensure that memory failure handling for anonymous pages, pagecaches pages works correctly, including proper SIGBUS delivery to user processes, page isolation, and recovery paths.
Currently madvise syscall is used to inject memory failures. And only anonymous pages and pagecaches are tested. More test scenarios, e.g. hugetlb, shmem, thp, will be added. Also more memory failure injecting methods will be supported, e.g. APEI Error INJection, if required.
This patch (of 3):
This patch adds a new kselftest to validate memory failure handling for anonymous pages. The test performs the following operations: 1. Allocates anonymous pages using mmap(). 2. Injects memory failure via madvise syscall. 3. Verifies expected error handling behavior. 4. Unpoison memory.
This test helps ensure that memory failure handling for anonymous pages works correctly, including proper SIGBUS delivery to user processes, page isolation and recovery paths.

selftests/mm: have the harness run each test category separately
At present the mm selftests are integrated into the kselftest harness by having it run run_vmtest.sh and letting it pick it's default set of tests to invoke, rather than by telling the kselftest framework about each test program individually as is more standard. This has some unfortunate interactions with the kselftest harness:
- If any of the tests hangs the harness will kill the entire mm selftests run rather than just the individual test, meaning no further tests get run. - The timeout applied by the harness is applied to the whole run rather than an individual test which frequently leads to the suite not being completed in production testing.
Deploy a crude but effective mitigation for these issues by telling the kselftest framework to run each of the test categories that run_vmtests.sh has separately. Since kselftest really wants to run test programs this is done by providing a trivial wrapper script for each categorty that invokes run_vmtest.sh, this is not a thing of great elegence but it is clear and simple. Since run_vmtests.sh is doing runtime support detection, scenario enumeration and setup for many of the tests we can't consistently tell the framework about the individual test programs.
This has the side effect of reordering the tests, hopefully the testing is not overly sensitive to this.

selftests/mm: remove virtual_address_range test
This self test is asserting internal implementation details and is highly vulnerable to internal kernel changes as a result.
It is currently failing
selftests/mm: remove virtual_address_range test
This self test is asserting internal implementation details and is highly vulnerable to internal kernel changes as a result.
It is currently failing locally from at least v6.17, and it seems that it may have been failing for longer in many configurations/hardware as it skips if e.g. CONFIG_ANON_VMA_NAME is not specified.
With these skips and the fact that run_vmtests.sh won't run the tests in certain configurations it is likely we have simply missed this test being broken in CI for a long while.
I have tried multiple versions of these tests and am unable to find a working bisect as previous versions of the test fail also.
The tests are essentially mmap()'ing a series of mappings with no hint and asserting what the get_unmapped_area*() functions will come up with, with seemingly few checks for what other mappings may already be in place.
It then appears to be mmap()'ing with a hint, and making a series of similar assertions about the internal implementation details of the hinting logic.
Commit 0ef3783d7558 ("selftests/mm: add support to test 4PB VA on PPC64"), commit 3bd6137220bb ("selftests/mm: virtual_address_range: avoid reading from VM_IO mappings"), and especially commit a005145b9c96 ("selftests/mm: virtual_address_range: mmap() without PROT_WRITE") are good examples of the whack-a-mole nature of maintaining this test.
The last commit there being particularly pertinent as it was accounting for an internal implementation detail change that really should have no bearing on self-tests, that is commit e93d2521b27f ("x86/vdso: Split virtual clock pages into dedicated mapping").
The purpose of the mm self-tests are to assert attributes about the API exposed to users, and to ensure that expectations are met.
This test is emphatically not doing this, rather making a series of assumptions about internal implementation details and asserting them.
It therefore, sadly, seems that the best course is to remove this test altogether.

selftests/mm: pass down full CC and CFLAGS to check_config.sh
check_config.sh checks that liburing is available by running the compiler provided as its first argument. This makes two assumptions:
1. CC consists of only one word 2. No extra flag is required
Unfortunately, there are many situations where these assumptions don't hold. For instance:
- When using Clang, CC consists of multiple words - When cross-compiling, extra flags may be required to allow the compiler to find headers
Remove these assumptions by passing down CC and CFLAGS as-is from the Makefile, so that the same command line is used as when actually building the tests.

selftests/mm: remove flaky header check
Commit 96ed62ea0298 ("mm: page_frag: fix a compile error when kernel is not compiled") introduced a check to avoid attempting to build the page_frag module if <linux/page_frag_cache.h> is missing.
Unfortunately this check only works if KDIR points to /lib/modules/... or an in-tree kernel build. It always fails if KDIR points to an out-of-tree build (i.e. when the kernel was built with O=... make) because only generated headers are present under $KDIR/include/ in that case.
A recent commit switched KDIR to default to the kernel's build directory, so that check is no longer justified.

selftests/mm: default KDIR to build directory
Patch series "Various mm kselftests improvements/fixes", v3.
Various improvements/fixes for the mm kselftests:
- Patch 1-3 extend support for more build configurations: out-of-tree $KDIR, cross-compilation, etc.
- Patch 4-7 fix issues related to faulting in pages, introducing a new helper for that purpose.
- Patch 8 fixes the value returned by pagemap_ioctl (PASS was always returned, which explains why the issue fixed in patch 6 went unnoticed).
- Patch 9 improves the exit code of pfnmap.
Net results: - 1 test no longer fails (patch 7) - 3 tests are no longer skipped (patch 4) - More accurate return values for whole suites (patch 8, 9) - Extra tests are more likely to be built (patch 1-3)
This patch (of 9):
KDIR currently defaults to the running kernel's modules directory when building the page_frag module. The underlying assumption is that most users build the kselftests in order to run them against the system they're built on.
This assumption seems questionable, and there is no guarantee that the module can actually be built against the running kernel.
Switch the default value of KDIR to the kernel's build directory, i.e. $(O) if O= or KBUILD_OUTPUT= is used, and the source directory otherwise. This seems like the least surprising option: the test module is built against the kernel that has been previously built.
Note: we can't use $(top_srcdir) in mm/Makefile because it is only defined once lib.mk is included.
