selftests: netconsole: only restore MAC when it changed on resume
The "mac" bind mode reactivation downs the interface, restores the saved
MAC and renames it to trigger a target resume. This assumes the recreated
interface comes back with a different MAC, which is true under
MACAddressPolicy=none (as on the Netdev CI) but not when MACs are
persistent. In the persistent case netconsole resumes the target on its
own, and the down/restore/rename flow instead drops it and fails the test.
Guard the block on the MAC having actually changed so the test passes
under both policies.

selftests/bpf: Cover tracing implicit kfunc args
KF_IMPLICIT_ARGS kfuncs have a BPF-call prototype and a real kernel target prototype. Add a tracing selftest that attaches fentry and fexit programs to bpf_kfunc_implicit_arg(), runs a syscall BPF program that calls it, and checks that the tracing context exposes both the explicit argument and the implicit prog aux pointer.

indicating a 32bit-wide instruction
- Another set of fixes addressing issues with translation of VNCR_EL2,
including corner cases where the guest point that register at a RO
page...
- Don't warn when trapping accesses to ZCR_EL2 from an L2 guest, as
that's not unexpected at all
- Address a bunch of races with LPI migration vs LPIs being disabled
- Fix a total howler of a bug combining FEAT_MOPS and NV, resulting in
exception returning in the wrong place...
- Move locking for kvm_io_bus_get_dev() into the caller, ensuring
race-free checks that the returned object is of the correct type
- Fix initialisation of the page-table walk level when relaxing
permissions
- Correctly update the XN attribute when relaxing permissions
- Fix the sign extension of loads from emulated MMIO regions
- Assorted collection of fixes for pKVM's FFA proxy, together with a
couple of FFA driver adjustments
- Coerce Fuad Tabba into a reviewer role, and may his Inbox catch fire!
s390:

disabled by the guest.
- Fix nVMX bugs where KVM would run L1 with an L1-controlled CR3 after a
failed "late" consistency check when KVM is NOT using EPT.
- Disallow intra-host migration/mirroring of SNP VMs as KVM doesn't yet
support moving/mirroring SNP state.
- Fix a TOCTOU bug in KVM's handling of the "trusted" CPUID for TDX guests.
- Fix a NULL pointer deref in trace_kvm_inj_exception() where a change to the

Add verifier coverage for constant negative offsets on PTR_TO_TP_BUFFER and PTR_TO_BUF pointers. Both programs adjust the buffer pointer by -8 and access it at offset zero, so the negative effective start must be rejected at load time. Switch the raw tracepoint writable attach checks from nbd_send_request to bpf_testmod_test_writable_bare_tp, avoiding a dependency on the NBD tracepoint. Keep the existing past-end case and add a case with a negative var_off compensated by a positive instruction offset. The effective start remains non-negative, so the program loads, but its access end exceeds the writable context size and bpf_raw_tracepoint_open() must return -EINVAL.

tracing fixes for 7.2:
- Free field in error path of synthetic event parse In __create_synth_event() the field was allocated but was not freed in the error path. - Fix ring_buffer_event_length() on 8 byte aligned architectures On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the ring_buffer_event_length() may return the wrong size. This is because archs with that config set will always use the "big event meta header" as that is 8 bytes keeping the payload 8 bytes aligned, even when a 4 byte header could hold the size of the event. But ring_buffer_event_length() doesn't take this into account and only subtracts 4 bytes for the meta header in the length when it should have subtracted 8 bytes. - Have osnoise wait for a full rcu synchronization on unregister osnoise_unregister_instance() used to call synchronize_rcu() before freeing its copy of the instance but was switched to kfree_rcu(). The osniose tracer has code that traverses the instances that it uses, and inst is just a pointer to that instance. By using kfree_rcu() instead of synchronize_rcu(), the instance that the inst pointer is pointing to can be freed while the osnoise code is still referencing it. That is, a rmdir on an instance first unregisters the tracer. When the unregister finishes, the rmdir expects that the tracer is finished with the instance that it is using. By putting back the synchronize_rcu() in osnoise_unregister_instance() the unregistering of osnoise will now return when all the users of the instance have finished. - Remove an unused setting of "ret" in tracing_set_tracer() - Fix ring_buffer_read_page() copying events The commit that changed ring_buffer_read_page() to show dropped events from the buffer itself, split the "commit" variable between the commit value (with flags) and "size" that holds the size of the sub-buffer. A cut and paste error changed the test of the reading from checking the size of the buffer to the size of the event causing reads to only read one event at a time. - Make tracepoint_printk a static variable When the tracing sysctl knobs were move from sysctl.c to trace.c, the variable tracepoint_printk no longer needed to be global. Make it static. - Fix some typos - Fix NULL pointer dereference in func_set_flag() The flags update of the function tracer first checks if the value of the flag is the same and exits if they are, and then it checks if the current tracer is the function tracer and exits if it isn't. The problem is that these checks need to be in a reversed order, as if the tracer isn't the function tracer, then the flag being checked may not exist. Reverse the order of these checks. - Fix ufs core trace events to not dereference a pointer in TP_printk() The TP_printk() part of the TRACE_EVENT() macro is called when the user reads the "trace" file. This can be seconds, minutes, hours, days, weeks, and even months after the data was recorded into the ring buffer. Thus, saving a pointer to an object into the ring buffer and then dereferencing it from TP_printk() can cause harm as the object the pointer is pointing to may no longer exist. Fix all the trace events in ufs core to save the device name in the ring buffer instead of dereferencing the device descriptor from TP_printk(). - Prevent out-of-bound reads in glob matching of trace events The filter logic of events allows simple glob logic to add wild cards to filter on strings. But some events have fields that may not have a terminating 'nul' character. This may cause the glob matching to go beyond the string. Change the logic to always pass in the length of the field that is being matched. - Add no-rcu-check version of trace_##event##_enabled() The trace_##event##_enabled() usually wraps trace events to do extra work that is only needed when the trace event is enabled. But this can hide events that are placed in locations where RCU is not watching, and can make lockdep not see these bugs when the event is not enabled. The trace_##event##_enabled() was updated to always test to make sure RCU is watching to catch locations that may call events without RCU being active. This caused a false positive for the irq_disabled() and related events. As that use trace_irq_disabled_enabled() to force RCU to be watching when the event is enabled via the ct_irq_enter() function, calls the event, and then calls ct_irq_exit() to put RCU back to its original state. The trace_irq_disabled_enabled() should not trigger a warning when RCU is not watching because the code within its block handles the case properly. Make a __trace_##event##_enabled() version for this event to use that doesn't check RCU is watching as it handles the case when it isn't. - Fix use-after-free in user_event_mm_dup() When the enabler is removed from the link list, it is freed immediately.

This is because archs with that config set will always use the "big event meta header" as that is 8 bytes keeping the payload 8 bytes aligned, even when a 4 byte header could hold the size of the event But ring_buffer_event_length() doesn't take this into account and only subtracts 4 bytes for the meta header in the length when it should have subtracted 8 bytes - Have osnoise wait for a full rcu synchronization on unregister osnoise_unregister_instance() used to call synchronize_rcu() before freeing its copy of the instance but was switched to kfree_rcu(). The osniose tracer has code that traverses the instances that it uses, and inst is just a pointer to that instance. By using kfree_rcu() instead of synchronize_rcu(), the instance that the inst pointer is pointing to can be freed while the osnoise code is still referencing it That is, a rmdir on an instance first unregisters the tracer. When the unregister finishes, the rmdir expects that the tracer is finished with the instance that it is using. By putting back the synchronize_rcu() in osnoise_unregister_instance() the unregistering of osnoise will now return when all the users of the instance have finished - Remove an unused setting of "ret" in tracing_set_tracer() - Fix ring_buffer_read_page() copying events The commit that changed ring_buffer_read_page() to show dropped events from the buffer itself, split the "commit" variable between the commit value (with flags) and "size" that holds the size of the sub-buffer. A cut and paste error changed the test of the reading from checking the size of the buffer to the size of the event causing reads to only read one event at a time - Make tracepoint_printk a static variable When the tracing sysctl knobs were move from sysctl.c to trace.c, the variable tracepoint_printk no longer needed to be global. Make it static - Fix some typos - Fix NULL pointer dereference in func_set_flag() The flags update of the function tracer first checks if the value of the flag is the same and exits if they are, and then it checks if the current tracer is the function tracer and exits if it isn't. The problem is that these checks need to be in a reversed order, as if the tracer isn't the function tracer, then the flag being checked may not exist. Reverse the order of these checks - Fix ufs core trace events to not dereference a pointer in TP_printk() The TP_printk() part of the TRACE_EVENT() macro is called when the user reads the "trace" file. This can be seconds, minutes, hours, days, weeks, and even months after the data was recorded into the ring buffer. Thus, saving a pointer to an object into the ring buffer and then dereferencing it from TP_printk() can cause harm as the object the pointer is pointing to may no longer exist Fix all the trace events in ufs core to save the device name in the ring buffer instead of dereferencing the device descriptor from TP_printk() - Prevent out-of-bound reads in glob matching of trace events The filter logic of events allows simple glob logic to add wild cards to filter on strings. But some events have fields that may not have a terminating 'nul' character. This may cause the glob matching to go beyond the string. Change the logic to always pass in the length of the field that is being matched - Add no-rcu-check version of trace_##event##_enabled() The trace_##event##_enabled() usually wraps trace events to do extra work that is only needed when the trace event is enabled. But this can hide events that are placed in locations where RCU is not watching, and can make lockdep not see these bugs when the event is not enabled The trace_##event##_enabled() was updated to always test to make sure RCU is watching to catch locations that may call events without RCU being active This caused a false positive for the irq_disabled() and related events. As that use trace_irq_disabled_enabled() to force RCU to be watching when the event is enabled via the ct_irq_enter() function, calls the event, and then calls ct_irq_exit() to put RCU back to its original state The trace_irq_disabled_enabled() should not trigger a warning when RCU is not watching because the code within its block handles the case properly. Make a __trace_##event##_enabled() version for this event to use that doesn't check RCU is watching as it handles the case when it isn't - Fix use-after-free in user_event_mm_dup() When the enabler is removed from the link list, it is freed immediately.

selftests/tracing: Have trigger-hist-poll.tc use sched_process_exit
Currently trigger-hist-poll.tc uses sched_process_free to test the polling of the histogram file. The way it does that is to run sleep, then execute the poll.c code that polls on the sched_process_free for up to 4 seconds to test that when sleep triggers the sched_process_free trace event, it will update the histogram and wake the poll.c code up. The issue is that sched_process_free trace event is called by delayed_put_task_struct() which is called after a RCU grace period has ended. If CONFIG_RCU_LAZY is enabled, RCU callbacks are batched together and do not execute right away. This causes the delayed_put_task_struct() to be called after the poll.c function finishes and it will report an error that it did not wake up on the event. That's because the event didn't trigger during its wait time. Use sched_process_exit instead, which is called when a process exits and doesn't depend on RCU callbacks that may be delayed.

selftests/landlock: Fix screwed up pointers in the scoped_signal_test
The scoped_signal_test uses pthread_join(..., (void **)&ret)) in
a couple of places, i.e. the return value of the thread is stored
in the shape of a "void *" into the memory location of &ret.
Pointers are 64-bit on modern computers, but the ret variable is
declared as a simple "enum thread_return" which is only 32 bits.
So the pthread_join() will overflow the ret variable by 4 byte.
The problem is very visible on big endian systems like s390x
where the test is failing: The least significant byte that carries
the return code of the thread is not written into the ret variable
here, but somewhere else in the stack frame, so the comparison
for the right return code is failing here.
Fix it by getting rid of the enum and defining the THREAD_* constants
and "ret" variables as proper "void *" pointers. This way we can
also get rid of some ugly (void *) castings in a couple of spots.

tools/sched_ext: scx - Fix cmask_subset(), cmask_equal() and cmask_weight()
cmask_equal(), cmask_weight() and cmask_subset() bounded their word walks
with CMASK_NR_WORDS(nr_cids), which pads by one word and can't tell the last
word in use without @base. The walks could thus cover a slack word past the
active range, which cmask_reframe() leaves non-zero: a stale bit there gave
cmask_equal() a spurious mismatch, cmask_weight() an inflated count, and
cmask_subset() a spurious violation. cmask_subset() could also read
@b->bits[] one word past its allocation (within the arena's fault-recovered
range, so harmless), and deviated from the kernel scx_cmask_subset() by
failing any @a range that doesn't nest inside @b's even when the overhanging
bits are all clear.
Bound the cmask_equal() and cmask_weight() walks by the words the range
actually spans, with early returns for empty ranges. Rewrite cmask_subset()
to match the kernel semantics: scan @a's overhangs for set bits with
cmask_next_set() and walk the words of the range intersection.
cmask_subset() moves below cmask_next_set(), which it now uses. Padding bits
don't need masking as every cmask helper keeps them clear.

selftests/net: fix EVP_MD_CTX leak in tcp_mmap
In tcp_mmap.c, both child_thread() and main() allocate an EVP_MD_CTX
via EVP_MD_CTX_new() when integrity checking is enabled, but neither
function releases the context. child_thread() misses the free in its
common cleanup block, and main() returns without freeing the context.
This results in a SHA256 context leak on every run that uses the
‑i (integrity) option. Add the missing EVP_MD_CTX_free() calls to
the appropriate cleanup paths to fix the leak.

selftests/sched_ext: Verify nohz_full tick behavior
Finite-slice EXT tasks need the periodic scheduler tick to expire their slices even when nohz_full is enabled. Add a regression test that selects a nohz_full CPU and exercises both infinite-to-finite and finite-to-finite slice transitions across an idle interval. For each finite task, verify that its ops.tick() callback is invoked. Skip the test when an allowed nohz_full CPU and a separate housekeeping CPU are not available.

selftests/rseq: Fix a building error for riscv arch
RISC-V rseq selftests include asm/fence.h from tools/arch/riscv,
but the rseq Makefile only adds tools/include in the CFLAGS, this
results in the building failure both for native and cross build:
In file included from rseq.h:131,
from rseq.c:37:
rseq-riscv.h:11:10: fatal error: asm/fence.h: No such file or directory
To fix it, add the matching tools/arch/$(ARCH)/include path in the
CFLAGS and derive ARCH from SUBARCH for standalone native builds where
ARCH is not set.

selftests/user_events: Wait for deferred event teardown after unregister
Unregistering a user event now defers the drop of the enabler's event
reference (and the freeing of the enabler) past an RCU grace period. As a
result DIAG_IOCSDEL can transiently fail with -EBUSY while that last
reference is still being dropped, where it previously succeeded
immediately.
Two tests assumed the delete takes effect the instant the unregister
returns:
- abi_test "flags" deletes the event right after disabling it.
- perf_test's fixture teardown clear() deletes __test_event before the
next test registers the same name; a stale event makes the following
registration fail with -EADDRINUSE.
Retry the delete until it succeeds (or the event is already gone) with a
bounded wait, matching the existing wait_for_delete() idiom in the same
suite, so the tests are robust to the deferred teardown.

usbip: tools: support SuperSpeedPlus devices
USB devices running at SuperSpeedPlus report "10000" or "20000" in
their sysfs speed attribute. usbip currently maps only "5000" to
USB_SPEED_SUPER, so a SuperSpeedPlus device is imported as
USB_SPEED_UNKNOWN.
The attach request is then rejected by vhci_hcd:
vhci_hcd: Failed attach request for unsupported USB speed: UNKNOWN
Map the SuperSpeedPlus sysfs speed values to USB_SPEED_SUPER_PLUS, use
the SuperSpeed VHCI hub for SuperSpeedPlus devices, and recognize the
gadget current_speed string used by the kernel.

selftests: riscv: Bypass libc in inactive vector ptrace test
The ptrace_v_not_enabled test expects the child to reach its ebreak before it has used the vector extension. That is not guaranteed when using fork(), because libc may run child atfork handlers before returning to the test code. In those cases PTRACE_GETREGSET for NT_RISCV_VECTOR then succeeds instead of returning ENODATA for inactive vector state. Use the raw clone syscall with SIGCHLD to keep fork-like semantics while bypassing libc's fork wrapper and atfork handler chain.

Issue those at EL0: SCTLR_EL1.EE would make an EL1 load big-endian but also walk the little-endian page tables big-endian, whereas SCTLR_EL1.E0E selects only EL0 data endianness and leaves the walk little-endian.

selftests/alsa: Fix format specifier and function mismatch in mixer-test
In the ctl_value_index_valid() function, when validating 64-bit integer controls (SND_CTL_ELEM_TYPE_INTEGER64), the error message for maximum value validation has two bugs: 1. Uses snd_ctl_elem_info_get_max() instead of the 64-bit variant snd_ctl_elem_info_get_max64() 2. Uses %ld format specifier instead of %lld for long long type This is inconsistent with the minimum value validation (line 335-339) which correctly uses get_min64() and %lld. The mismatch can cause: - Incorrect maximum values being reported on some architectures - Undefined behavior due to format specifier mismatch - Potential crashes when printing the error message Fix by using snd_ctl_elem_info_get_max64() and %lld format specifier to match the data type and be consistent with the minimum value check.

Pull vfs fixes from Christian Brauner:
- netfs:
- fix the decision when to disallow write-streaming with fscache in
use, handling of asynchronous cache object creation, a double fput
in cachefiles, clearing S_KERNEL_FILE without the inode lock held,
page extraction bugs in the iov_iter helpers (a potential
underflow, a missing allocation failure check, a memory leak, and
a folio offset miscalculation), writeback error and ENOMEM
handling, DIO write retry for filesystems without a
->prepare_write() method, and the replacement of the wb_lock mutex
with a bit lock plus writethrough collection offload so that
multiple asynchronous writebacks don't interfere with each other.
- Fix the barriering when walking the netfs subrequest list during
retries as it was possible to see a subrequest that was just added
by the application thread.
- iomap:
- Change iomap to submit read bios after each extent instead of
building them up across extents. The old behavior was considered
problematic for a while and now caused an actual erofs bug.
- Guard the ioend io_size EOF trim in iomap against underflow when a
concurrent truncate moves EOF below the start of the ioend,
wrapping io_size to a huge value.
- overlayfs
- Fix a stale overlayfs comment about the locking order.
- Store the linked-in upper dentry instead of the disconnected
O_TMPFILE dentry during overlayfs tmpfile copy-up. With a FUSE or
virtiofs upper layer ->d_revalidate() would try to look up "/" in
the workdir and fail, causing persistent ESTALE errors that broke
dpkg and apt.
- vfs-bpf:
Have the bpf_real_data_inode() kfunc take a struct file instead of a
dentry so it is usable from the bprm_check_security, mmap_file, and
file_mprotect hooks, and rename it from bpf_real_inode() to make the
data-inode semantics explicit. The kfunc landed this cycle so the
change is safe.
- afs:
NULL pointer dereferences in the callback service and in
afs_get_tree(), several memory and refcount leaks, missing locking
around the dynamic root inode numbers and premature cell exposure
through /afs, a netns destruction hang caused by a misplaced
increment of net->cells_outstanding, a bulk lookup malfunction caused
by the dir_emit() API change, inode (re)initialisation issues, and
assorted smaller fixes to error codes, seqlock handling, and debug
output.
- vfs:
Refuse O_TMPFILE creation with an unmapped fsuid or fsgid and add a
selftest for it.
- vboxsf:
Add Jori Koolstra as vboxsf maintainer, taking over from Hans de
Goede.
- dio:
Release the pages attached to a short atomic dio bio; the REQ_ATOMIC
size check error path leaked them.
- procfs:
Only bump the parent directory link count when registering
directories in procfs. Registering regular files inflated the count
and leaked a link on every create and remove cycle.
- minix:
Avoid an unsigned overflow in the minix bitmap block count
calculation that let crafted images with huge inode or zone counts
pass superblock validation and crash the kernel during mount.
- cachefiles:
Fix a double unlock in the cachefiles nomem_d_alloc error path left
over from the start_creating() conversion.
- fat:
Stop fat from reading directory entries past the 0x00
end-of-directory marker. If the trailing on-disk slots aren't
zero-filled the driver surfaced arbitrary garbage as directory
entries.
- freexvfs:
Don't BUG() on unknown typed-extent types in freevxfs, reachable via
ioctl(FIBMAP) on a crafted image; fail with an I/O error instead.
- orangefs:
Keep the readdir entry size 64-bit in orangefs fill_from_part().
Truncating it to __u32 bypassed the bounds check and led to
out-of-bounds reads triggerable by the userspace client.
- xfs:
Fix the error unwind in xfs_open_devices() which released the rt
device file twice and left dangling buftarg pointers behind that were
freed again when the failed mount was torn down.
- exec:
Fix an off-by-one in the comment documenting the maximum binfmt
rewrite depth in exec_binprm(). The code allows five rewrites, not
four; restricting the code would break userspace so the comment is
fixed instead.
- file handles:
Reject detached mounts in capable_wrt_mount(). A detached mount can
be dissolved concurrently, leaving a NULL mount namespace that
open_by_handle_at() would dereference.
