- dsa: bcm_sf2: fix array overrun in bcm_sf2_num_active_ports()
Previous releases - regressions:
- introduce a shutdown method to mdio device drivers, and make DSA
switch drivers compatible with masters disappearing on shutdown;
preventing infinite reference wait

selftests: netfilter: add selftest for directional zone support
Add a script to exercise NAT port clash resolution with directional zones.
Add net namespaces that use the same IP address and connect them to a
gateway.
Gateway uses policy routing based on iif/mark and conntrack zones to
isolate the client namespaces. In server direction, same zone with NAT
to single address is used.
Then, connect to a server from each client netns, using identical
connection id, i.e. saddr:sport -> daddr:dport.
Expectation is for all connections to succeeed: NAT gatway is
supposed to do port reallocation for each of the (clashing) connections.
This is based on the description/use case provided in the commit message of

powerpc fixes for 5.15 #2
Fix crashes when scv (System Call Vectored) is used to make a syscall when a transaction is active, on Power9 or later. Fix bad interactions between rfscv (Return-from scv) and Power9 fake-suspend mode. Fix crashes when handling machine checks in LPARs using the Hash MMU. Partly revert a recent change to our XICS interrupt controller code, which broke the recently added Microwatt support.

selftests: net: af_unix: Fix makefile to use TEST_GEN_PROGS
Makefile uses TEST_PROGS instead of TEST_GEN_PROGS to define executables. TEST_PROGS is for shell scripts that need to be installed and run by the common lib.mk framework. The common framework doesn't touch TEST_PROGS when it does build and clean. As a result "make kselftest-clean" and "make clean" fail to remove executables. Run and install work because the common framework runs and installs TEST_PROGS. Build works because the Makefile defines "all" rule which is unnecessary if TEST_GEN_PROGS is used. Use TEST_GEN_PROGS so the common framework can handle build/run/ install/clean properly. Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: David S. Miller <davem@davemloft.net> |

Minimal selftest which implements a small BPF policy program to the connect(2) hook which rejects TCP connection requests to port 60123 with EPERM.

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/bpf: Fix build of task_pt_regs test for arm64
struct pt_regs is not exported to userspace on all archs. arm64 and s390
export "user_pt_regs" instead, which causes build failure at the moment:
progs/test_task_pt_regs.c:8:16: error: variable has incomplete type 'struct pt_regs'
struct pt_regs current_regs = {};
Instead of using pt_regs from ptrace.h, use the larger kernel struct
from vmlinux.h directly. Since the test runner task_pt_regs.c does not
have access to the kernel struct definition, copy it into a char array.

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 ... |

selftests: mptcp: clean tmp files in simult_flows
'$cin' and '$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.
