selftests/ftrace: Exclude "(fault)" in testing add/remove eprobe events
The original test for adding and removing eprobes used synthetic events
and retrieved the filename from the open system call at the end of the
system call. This would allow it to always be loaded into the page tables
when accessed.
Masami suggested that the test was too complex for just testing add and
remove, so it was changed to test just adding and removing an event probe
on top of the start of the open system call event. Now it is possible that
the filename will not be loaded into memory at the time the eprobe is
triggered, and will result in "(fault)" being displayed in the event. This
causes the test to fail.
Account for "(fault)" also being one of the values of the filename field
of the event probe.

selftests: vm: add COW time test for KSM pages
Since merged pages are copied every time they need to be modified, the write access time is different between shared and non-shared pages. Add ksm_cow_time() function which evaluates latency of these COW breaks. First, 4000 pages are allocated and the time, required to modify 1 byte in every other page, is measured. After this, the pages are merged into 2000 pairs and in each pair, 1 page is modified (i.e. they are decoupled) to detect COW breaks. The time needed to break COW of merged pages is then compared with performance of non-shared pages. The test is run as follows: ./ksm_tests -C The output: Total size: 15 MiB Not merged pages: Total time: 0.002185489 s Average speed: 3202.945 MiB/s Merged pages: Total time: 0.004386872 s Average speed: 1595.670 MiB/s Link: https://lkml.kernel.org/r/1d03ee0d1b341959d4b61672c6401d498bff5652.1629386192.git.zhansayabagdaulet@gmail.com Signed-off-by: Zhansaya Bagdauletkyzy <zhansayabagdaulet@gmail.com> Reviewed-by: Tyler Hicks <tyhicks@linux.microsoft.com> Reviewed-by: Pavel Tatashin <pasha.tatashin@soleen.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Add check_ksm_numa_merge() function to test that pages in different NUMA nodes are being handled properly. First, two duplicate pages are allocated in two separate NUMA nodes using the libnuma library. Since there is one unique page in each node, with merge_across_nodes = 0, there won't be any shared pages. If merge_across_nodes is set to 1, the pages will be treated as usual duplicate pages and will be merged.

selftests: vm: add KSM merge test
Patch series "add KSM selftests". Introduce selftests to validate the functionality of KSM. The tests are run on private anonymous pages. Since some KSM tunables are modified, their starting values are saved and restored after testing. At the start, run is set to 2 to ensure that only test pages will be merged (we assume that no applications make madvise syscalls in the background). If KSM config not enabled, all tests will be skipped. This patch (of 4): Add check_ksm_merge() function to check the basic merging feature of KSM. First, some number of identical pages are allocated and the MADV_MERGEABLE advice is given to merge these pages. Then, pages_shared and pages_sharing values are compared with the expected numbers using assert_ksm_pages_count() function. The number of pages can be changed using -p option.

selftests/vm/userfaultfd: wake after copy failure
When userfaultfd copy-ioctl fails since the PTE already exists, an -EEXIST
error is returned and the faulting thread is not woken. The current
userfaultfd test does not wake the faulting thread in such case. The
assumption is presumably that another thread set the PTE through copy/wp
ioctl and would wake the faulting thread or that alternatively the fault
handler would realize there is no need to "must_wait" and continue. This
is not necessarily true.
There is an assumption that the "must_wait" tests in handle_userfault()
are sufficient to provide definitive answer whether the offending PTE is
populated or not. However, userfaultfd_must_wait() test is lockless.
Consequently, concurrent calls to ptep_modify_prot_start(), for instance,
can clear the PTE and can cause userfaultfd_must_wait() to wrongly assume
it is not populated and a wait is needed.
There are therefore 3 options:
(1) Change the tests to wake on copy failure.
(2) Wake faulting thread unconditionally on zero/copy ioctls before
returning -EEXIST.
(3) Change the userfaultfd_must_wait() to hold locks.
This patch took the first approach, but the others are valid solutions
with different tradeoffs.

mm: remove flush_kernel_dcache_page
flush_kernel_dcache_page is a rather confusing interface that implements a
subset of flush_dcache_page by not being able to properly handle page
cache mapped pages.
The only callers left are in the exec code as all other previous callers
were incorrect as they could have dealt with page cache pages. Replace
the calls to flush_kernel_dcache_page with calls to flush_dcache_page,
which for all architectures does either exactly the same thing, can
contains one or more of the following:
1) an optimization to defer the cache flush for page cache pages not
mapped into userspace
2) additional flushing for mapped page cache pages if cache aliases
are possible

selftests/vm: use kselftest skip code for skipped tests
There are several test cases in the vm directory are still using exit 0 when they need to be skipped. Use the kselftest framework to skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in vm directory: grep -r "exit 0" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

arm64 updates for 5.15:
- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the scheduler changes merged via the tip tree). - More entry.S clean-ups and conversion to C. - MTE updates: allow a preferred tag checking mode to be set per CPU (the overhead of synchronous mode is smaller for some CPUs than others); optimisations for kernel entry/exit path; optionally disable MTE on the kernel command line. - Kselftest improvements for SVE and signal handling, PtrAuth. - Fix unlikely race where a TLBI could use stale ASID on an ASID roll-over (found by inspection). - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher exception levels; drop unnecessary sigdelsetmask() call in the signal32 handling; remove BUG_ON when failing to allocate SVE state (just signal the process); SYM_CODE annotations. - Other trivial clean-ups: use macros instead of magic numbers, remove redundant returns, typos. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmEuYkoACgkQa9axLQDI XvEWVw/9HSWbccLrQ68ulaqZkL4r6lL2RqvZ2p6fkIRW7bX1JS4UJjWe3+VBg5Ed DQ1A5cHC5ZndQ4gCRsUhcq7IMXBSj3twMzK7yxBk3zh8tbhVrIOONsKMurMw1NyM OmoyTJ01i2ZrkDs0OU3fBlvIHPxBjKbOZqykOJHjrB2rwBSbsyUw2KvpM7ha8DOf O7gKViDrdAhumdIL9rsMvSiIPoJLCxvqeu55c3saVu1JrUR6ENu7lMu3jt4WrfK3 m5gf76IFbgxXvlLiC8RJW7OYaXZ+COb7RA/yP/lK+Y0ug9PwqTpzXDwqvAp8nBIv y7DK0umcBwfDWmwnRO+ZzNPjOGTHnOnjC07WNBPn3v03pMeJ8v8RnvzHkliek31P r6uFWBxWO/O0sBbSpR+4tzgNfir0RkMajwL5pxQCEMoPCucStYQQl8zIeJeJecpT DKIyKzfFw6O59gdhE6dCj2wXH8YmKUoSUPCAXpKGzK/oYVOGVQTZSZjIC++ydFWv AOXz77etPidk3/Tl15Ena7fkkMkxX9UM8dTjOFS64mSWlEyzE6FtfAgm2rIEOaG7 ps6IjVzVves39SC+yry8T2L6gsxPnanRfwKKCWHkovQzNFgs5Qt51Fd5eIeI1jZ0 uEZhd19FN4136QhjWJOeXL/eyj0bv1WLX/mUln95sHnKyf4je9w= =X6Wm -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Support for 32-bit tasks on asymmetric AArch32 systems (on top of the scheduler changes merged via the tip tree). - More entry.S clean-ups and conversion to C. - MTE updates: allow a preferred tag checking mode to be set per CPU (the overhead of synchronous mode is smaller for some CPUs than others); optimisations for kernel entry/exit path; optionally disable MTE on the kernel command line. - Kselftest improvements for SVE and signal handling, PtrAuth. - Fix unlikely race where a TLBI could use stale ASID on an ASID roll-over (found by inspection). - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher exception levels; drop unnecessary sigdelsetmask() call in the signal32 handling; remove BUG_ON when failing to allocate SVE state (just signal the process); SYM_CODE annotations. - Other trivial clean-ups: use macros instead of magic numbers, remove redundant returns, typos. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (56 commits) arm64: Do not trap PMSNEVFR_EL1 arm64: mm: fix comment typo of pud_offset_phys() arm64: signal32: Drop pointless call to sigdelsetmask() arm64/sve: Better handle failure to allocate SVE register storage arm64: Document the requirement for SCR_EL3.HCE arm64: head: avoid over-mapping in map_memory arm64/sve: Add a comment documenting the binutils needed for SVE asm arm64/sve: Add some comments for sve_save/load_state() kselftest/arm64: signal: Add a TODO list for signal handling tests kselftest/arm64: signal: Add test case for SVE register state in signals kselftest/arm64: signal: Verify that signals can't change the SVE vector length kselftest/arm64: signal: Check SVE signal frame shows expected vector length kselftest/arm64: signal: Support signal frames with SVE register data kselftest/arm64: signal: Add SVE to the set of features we can check for arm64: replace in_irq() with in_hardirq() kselftest/arm64: pac: Fix skipping of tests on systems without PAC Documentation: arm64: describe asymmetric 32-bit support arm64: Remove logic to kill 32-bit tasks on 64-bit-only cores arm64: Hook up cmdline parameter to allow mismatched 32-bit EL0 arm64: Advertise CPUs capable of running 32-bit applications in sysfs ... |

'$cin' and '$sin' variables are local to a function: they are then not
available from the cleanup trap.
Instead, we need to use '$large' and '$small' that are not local and
defined just before setting the trap.
Without this patch, running this script in a loop might cause a:

Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did the
following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
The latter one will cause a tiny merge issue with your tree, as there
was a last-minute fix for this in 5.14 in your tree, but the fixup
should be "obvious". If you want me to provide a fixed merge for this,
please let me know.
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs
users at once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue.

"This contains an extension to the move_mount() syscall making it
possible to add a single private mount into an existing propagation
tree.
The use-case comes from the criu folks which have been struggling with
restoring complex mount trees for a long time. Variations of this work
have been discussed at Plumbers before, e.g.
https://www.linuxplumbersconf.org/event/7/contributions/640/
The extension to move_mount() enables criu to restore any set of mount
namespaces, mount trees and sharing group trees without introducing
yet more complexity into mount propagation itself.
The changes required to criu to make use of this and restore complex
propagation trees are available at
https://github.com/Snorch/criu/commits/mount-v2-poc
A cleaned-up version of this will go up for merging into the main criu
repo after this lands"

"RCU changes for this cycle were:
- Documentation updates
- Miscellaneous fixes
- Offloaded-callbacks updates
- Updates to the nolibc library
- Tasks-RCU updates
- In-kernel torture-test updates
- Torture-test scripting, perhaps most notably the pinning of
torture-test guest OSes so as to force differences in memory
latency. For example, in a two-socket system, a four-CPU guest OS
will have one pair of its CPUs pinned to threads in a single core
on one socket and the other pair pinned to threads in a single core
on the other socket. This approach proved able to force race
conditions that earlier testing missed. Some of these race
conditions are still being tracked down"

selftests: Skip TM tests on synthetic TM implementations
Transactional Memory was removed from the architecture in ISA v3.1. For threads running in P8/P9 compatibility mode on P10 a synthetic TM implementation is provided. In this implementation, tbegin. always sets cr0 eq meaning the abort handler is always called. This is not an issue as users of TM are expected to have a fallback non transactional way to make forward progress in the abort handler. The TEXASR indicates if a transaction failure is due to a synthetic implementation. Some of the TM self tests need a non-degenerate TM implementation for their testing to be meaningful so check for a synthetic implementation and skip the test if so.

selftests/powerpc: Add missing clobbered register to to ptrace TM tests
ISA v3.1 removes TM but includes a synthetic implementation for backwards compatibility. With this implementation, the tests ptrace-tm-spd-gpr and ptrace-tm-gpr should never be able to make any forward progress and eventually should be killed by the timeout. Instead on a P10 running in P9 mode, ptrace_tm_gpr fails like so: test: ptrace_tm_gpr tags: git_version:unknown Starting the child ... ... GPR[27]: 1 Expected: 2 GPR[28]: 1 Expected: 2 GPR[29]: 1 Expected: 2 GPR[30]: 1 Expected: 2 GPR[31]: 1 Expected: 2 [FAIL] Test FAILED on line 98 failure: ptrace_tm_gpr selftests: ptrace-tm-gpr [FAIL] The problem is in the inline assembly of the child. r0 is loaded with a value in the child's transaction abort handler but this register is not included in the clobbers list. This means it is possible that this statement: cptr[1] = 0; which is meant to signal the parent to wait may actually use the value placed into r0 by the inline assembly incorrectly signal the parent to continue. By inspection the same problem is present in ptrace-tm-spd-gpr. Adding r0 to the clobbbers list makes the test fail correctly via a timeout on a P10 running in P8/P9 compatibility mode.

selftests/net: allow GRO coalesce test on veth
This change extends the existing GRO coalesce test to allow running on top of a veth pair, so that no H/W dep is required to run them. By default gro.sh will use the veth backend, and will try to use exiting H/W in loopback mode if a specific device name is provided with the '-i' command line option. No functional change is intended for the loopback-based tests, just move all the relevant initialization/cleanup code into the related script. Introduces a new initialization helper script for the veth backend, and plugs the correct helper script according to the provided command line. Additionally, enable veth-based tests by default. v1 -> v2: - drop unused code in setup_veth_ns() - Willem Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

The next test requires to setsockopt(TCP_CONGESTION) before connect(), so a new arg is needed for the connect_to_fd() to specify the cc's name.

selftests/x86: Fix error: variably modified 'altstack_data' at file scope
A glibc 2.34 feature adds support for variable MINSIGSTKSZ and SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer constant on Linux. glibc 2.34 flags code paths assuming MINSIGSTKSZ or SIGSTKSZ are constant. Fix these error in x86 test. Feature description and build error: NEWS for version 2.34 ===================== Major new features: * Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ) and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports dynamic sized register sets for modern architectural features like Arm SVE. ===================== If _SC_SIGSTKSZ_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are redefined as: /* Default stack size for a signal handler: sysconf (SC_SIGSTKSZ). */ # undef SIGSTKSZ # define SIGSTKSZ sysconf (_SC_SIGSTKSZ) /* Minimum stack size for a signal handler: SIGSTKSZ. */ # undef MINSIGSTKSZ # define MINSIGSTKSZ SIGSTKSZ Compilation will fail if the source assumes constant MINSIGSTKSZ or SIGSTKSZ.
