2026-08-20net/mlx5: Move vport DOWN state check out of mlx5_query_vport_max_tx_speed()Or Har-Toov
mlx5_query_vport_max_tx_speed() was introduced to serve the query_port_speed path, which uses max_tx_speed == 0 when port is down. This is incorrect for callers that need the actual configured speed regardless of vport state, such as modify-vport-state helpers that must preserve the speed across state transitions. Move this logic to the caller function in the verb flow and let mlx5_query_vport_max_tx_speed() return the raw firmware value unconditionally.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext updates from Tejun Heo: "Most of this cycle completes the enqueue-path support for hierarchical sub-scheduling, which makes sub-scheduler support feature complete: a root BPF scheduler can now hand a cgroup subtree over to a nested sub-scheduler together with revocable CPU grants, and the sub-scheduler owns all scheduling decisions for its tasks on those CPUs. Development volume was high and a number of changes plugging holes in the new support landed late in the cycle. Also included are core scheduling fixes that were completed too late for the v7.2 release and are routed through this pull request. Sub-scheduler CPU delegation: - Parent schedulers now grant and revoke per-CPU capabilities (enqueueing, preemption, CPU frequency control) on their children, enforced on every path a scheduler can reach a CPU through. Previously only dispatching could be delegated; this lets sub-schedulers fully schedule their CPUs. - Rescue execution: a task whose scheduler doesn't have access to the CPUs the task needs to run on starved until the watchdog ejected the whole scheduler. The kernel now runs such tasks directly on a small bandwidth budget, turning a scheduler-killing failure into bounded degradation. - Cgroup integration: tasks migrating across a sub-scheduler boundary weren't re-homed to the new owner, causing wrong-scheduler scheduling and a use-after-free. Sub-schedulers now take over their cgroup subtree and receive its cgroup callbacks. - Arena objects now cross the kernel/BPF boundary as typed pointer arguments, translated transparently by the BPF tree's new arena argument support, replacing untyped arguments with manual translation. - scx_qmap now demonstrates full hierarchical sub-scheduling. Other fixes and updates: - Robustness improvements: the abort path is now NMI-safe, fixing deadlocks when errors are raised from NMI context and making hardlockup recovery direct. Reenqueue loops that could monopolize a CPU ahead of the watchdog now eject the offending scheduler, and stalls are blamed on the scheduler actually responsible. - Hardening: BPF-writable arena memory is validated before kernel use, and task slice and vtime writes got explicit synchronization rules, closing corruption vectors open to buggy or malicious schedulers. - Core scheduling: sched_ext dispatching can drop the rq lock inside the core-wide pick, which let interleaving selections corrupt each other's state and hard-hang the machine. The selection now restarts when the lock was released. The task ordering callback was also invoked with its arguments swapped, and the default ordering is updated to work across sub-scheduler boundaries. The fixes are marked for stable. - Other fixes headed for stable: a task init leak on fork failure during enable, tooling compat macros that silently failed to detect newer kernels, and a crash on reenqueueing against a destroyed dispatch queue. - Tooling: scx_pair moves off deprecated callbacks, and the deprecated scx_bpf_cpu_rq() kfunc is removed" * tag 'sched_ext-for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: (144 commits) sched_ext: Drop the dead SCX_DEQ_CORE_SCHED_EXEC test in dequeue_task_scx() sched_ext: Make core-sched task ordering hierarchy-aware sched_ext: Use runnable_at for the default core-sched task ordering sched_ext: Fix inverted ops.core_sched_before() invocation sched_ext: Move the config-off sub-cap kfunc stubs into sub.c sched_ext: Rename balance-era identifiers to dispatch terms sched_ext: Drop the stale keep_prev fixup in dispatch_pick() sched_ext: Keep kick_sync waiting on the rq's own CPU sched_ext: Make SCHED_CLASS_EXT select GENERIC_ALLOCATOR sched_ext/scx_flatcg: Fix cvtime true-up on slice expiry sched_ext: Don't BUG_ON a destroyed DSQ in process_deferred_reenq_users sched_ext: Fix scx_bpf_dsq_move_to_local___v2 compat detection sched_ext: Make scx_bpf_events() read the calling scheduler's counters sched_ext: Drop unlocked scx_rq_clock_invalidate() from scx_root_disable() selftests/sched_ext: Fix flaky ddsp failure tests on busy systems selftests/sched_ext: Make numa idle validation race-free sched_ext: Fix scx_bpf_dsq_reenq___compat kfunc extern prototype sched_ext/scx_flatcg: expire cached hweights on weight changes sched_ext: Fix exit_task leak on fork failure during enable sched_ext: fix stale references in doc comments ...

Rebinding also now runs once per process instead of repeating for every thread sharing the mm. - Overhead removals with no behavior change: CPU hotplug iterated tasks of cpusets that just inherit the parent's effective masks, and the slab-spreading task flag was still being maintained although the SLAB allocator that consumed it is long gone. - Data-race annotations for benign races so that KCSAN reports stay meaningful, selftest coverage for the fixes above along with flakiness and portability fixes, and documentation corrections. * tag 'cgroup-for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: (34 commits) selftests/cgroup: Remove redundant chown in test_cgcore_lesser_ns_open selftests/cgroup: Preserve CPU hotplug write errors cgroup/cpuset: Add test for partition root invalidation returning wrong CPUs cgroup/cpuset: Remove obsolete PFA_SPREAD_SLAB task flag docs: cgroup-v2: fix stale "io" controller introduction selftests/cgroup: Avoid awk -e in cpuset tests cgroup/cpuset: Use WRITE_ONCE() for shared prs_err updates selftests/cgroup: add user_usec sanity check in test_cpucg_nice cgroup: drop unneeded semicolon docs: cgroup-v2: mark memory.pressure and io.pressure as read-write selftests/cgroup: Fix minor defects in test_cpuset Docs/admin-guide/cgroup-v2: fix delay_nsec unit in io.latency doc selftests/cgroup: Remove redundant cg_enter_current() call in test_core selftests/cgroup: Add test for cpuset affinity on controller disable cgroup/cpuset: Handle the special case of non-moving tasks in cpuset_can_attach() cgroup/cpuset: Support multiple destination cpusets for cpuset_*attach() selftests/cgroup: fix missing TAP output in test_hugetlb_memcg cgroup/cpuset: Support multiple source cpusets for cpuset_*attach() cgroup/cpuset: Move mpol_rebind_mm/cpuset_migrate_mm() calls inside cpuset_attach_task() cgroup/cpuset: Make attach_ctx.old_cs track task group leader ...

2026-08-20x86/bpf: Make arch_bpf_trampoline_size allocate from EXECMEM_MODULE_DATAMike Rapoport (Microsoft)
Jiri Olsa reports slowdown of tracing_multi benchmark that allocates huge number of trampolines [1]. The slowdown caused by extra protection changes in execmem_alloc_rw() and execmem_free(). With ROX caches enabled, all execmem allocations except EXECMEM_MODULE_DATA are ROX after the allocation. execmem_alloc_rw() temporarily sets them to W+NX and execmem_free() resets them back to ROX. The only user of bpf_jit_alloc_exec_rw() is x86::arch_bpf_trampoline_size() that only needs a temporary writable buffer in the modules address space. On x86 executable memory and module data are constrained to the same address range, so x86::arch_bpf_trampoline_size() can directly use execmem_alloc(EXECMEM_MODULE_DATA) Replace the call to bpf_jit_alloc_exec_rw() with a call to execmem_alloc(EXECMEM_MODULE_DATA) in x86::arch_bpf_trampoline_size() and drop bpf_jit_alloc_exec_rw() helper.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "One of the 'small improvements all over the place' releases for us. It's hard to draw any direct comparisons because summer vacations disrupted our patch processing (and presumably - generation) quite a bit. Quick and dirty count suggests we (Paolo and I) merged a very similar number of net (632) and net-next (648) patches. This is not telling the full story either because 1/3 to 1/2 of the net-next patches also *seem* like AI-driven low priority fixes, cleanups and clarifications. We are completely overwhelmed, of course. The glimmer of hope is that we secured sufficient LLM budget and access (thank you Meta!) to run reviews with multiple frontier models on each patch. This eliminates some hallucinations. That said, in terms of review, the LLMs can only do so much. The sad truth is that our APIs (especially for rare events like PCIe errors, timeouts etc) have always been racy, and now LLMs don't let us ignore that. I expect our direction for the next release will be to tweak the reviews a little bit more, but start shifting focus to letting the LLMs take care of the busy work - managing patchwork, automating common process complaints, editing commit messages, and maybe applying patches which already got "reviewed-by" tags from people we trust... Core & protocols: - A few steps lowering rtnl_lock dependence: - per-netns netdev unregistration for select SW drivers (e.g. veth, ipvlan, tunnels) - rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE) -

Report the per-group user count via RTM_GETMULTICAST - Expose the route deletion reason in RTM_DELROUTE - Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more useful handling of LSM denials when receiving SCM_RIGHTS messages: instead of truncating the message at the first blocked fd, keep every fd slot and store the LSM errno in the blocked slot - IPv6 Segment Routing - support looking up the post-encap SID (address) in a different/specified routing table - Support PRP RedBox (interlink) creation - Support per-nexthop UDP dst port in VXLAN - Continue converting getsockopt callbacks in a number of protocols to iov_iter Ethernet: -

The callchain is sched_rt_handler() -> partition_sched_domains() -> sched_cache_set() -> static_key_enable_cpuslocked(&sched_cache_present). sched_cache_set() itself is also invoked from sched_init_domains() which is early during the boot, holding just the sched_domains_mutex_lock(). Here is no warning because it happens before user space is running (and hotplug operations are not possible). There is also sched_cache_active_set() which acquires the hotplug lock before invoking any of the _cpuslocked() functions. This is only a problem with CONFIG_CPUSETS=n because in the =y case the other implementation of rebuild_sched_domains acquires the CPU-hotplug lock. Acquire CPU hotplug lock before in rebuild_sched_domains(), before partition_sched_domains() is invoked for the CONFIG_CPUSETS=n case.

2026-08-20irqchip/gic-v5: Release IRS iomem region on driver init failureLorenzo Pieralisi
In gicv5_irs_of_init(), an IRS is set-up using of_io_request_and_map() to request its memory region (corresponding to the configuration frame) and map the IRS configuration frame. On gicv5_irs_of_init() failure, the driver unmaps the IRS iomem region but does not release the requested memory region leaving it allocated in the iomem resource tree. Fix it by releasing the iomem region on gicv5_irs_of_init() probe failure. Likewise, on both OF and ACPI driver init failure, IRS iomem regions are requested but never released in gicv5_irs_remove(). Stash a copy of the IRS iomem region in a struct resource in struct gicv5_irs_chip_data and use it to release the requested region in gicv5_irs_remove() if the driver probe fails.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Expose btf_ids to trace events In order to allow BPF programs to attach to system call trace events (which are actually pseudo trace events built on top of raw_syscall events), expose the BTF ID of the events. This will allow BPF programs better precision in attaching to events. - Use "u64" to assign to hist_field->type Instead of using kstrdup("u64", GFP_KERNEL) to assign the hist_field->type, just point it to "u64" instead. The hist_field->type is freed via kfree_const(). - Replace kmalloc()/strcpy() with kstrdup() for trace_printk Instead of having two calls to copy the module format string, just use kstrdup(). - Use __free() in trace event histograms and triggres where possible - Use seq_buf in trace event code instead of strcat() Instead of calculating the size of the buffer to use and filling it with strcat(), use the seq_buf infrastructure that takes care of making sure not to overflow the string size. - Reject invalid preemptirq_delay_test CPU affinity The preempt_delay_test module can take an invalid CPU affinity mask and create confusing output. Simply have the module reject invalid affinity masks. - Prevent division by zero in ftrace_ops sample module code If the ftrace_ops sample module code receives the module parameter nr_function_calls set to zero, it can cause a division by zero error. - Warn when an event dereferences a parameter in TP_printk() On boot up and module load, the trace event TP_printk() is scanned for possible bugs. As the TP_printk() code is executed when the user reads the "trace" file and processes the data written when the trace_event executed, the data it reads can be literally days old. The scan currently checks for dereferencing printk formats like "%pI6". But it does not check if the parameters themselves have a dereference like: TP_printk("offset %08x: value %08x", (u32)(__entry->addr - __entry->edma->membase), __entry->value) __entry represents the pointer to the event on the ring buffer. The __entry->edma->membase is dereferencing a pointer on the ring buffer to find membase, but the __entry->edma may no longer be a valid pointer. Warn on this case too. - Replace some strcpy() with strscpy() - Clean up mmiotrace events to use assign_type() macro The assign_type() macro makes sure the event type is indeed the type that is being parsed. The mmiotrace trace was written before that macro was created so it just simply typecasted the pointer. Replace the typecasting with the macro. - Have the ENUM processing to numbers only process what is added The code that converts ENUMs to their numbers in the trace events scanned all events to do the processing. This was true when a module was loaded too. That is, instead of processing just the events for the module, it processed *all* events. Even the builtin ones that were processed at boot up. Add a check for the event->module matching mod if it is a module before processing it. * tag 'trace-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (21 commits) tracing: Have trace_event_update_all() only handle module that is loading tracing: Cleanup event_enable_trigger_parse() by using __free() tracing: Report every TP_printk double dereference tracing/mmiotrace: Use trace_assign_type() in mmio_print_mark() tracing: Make per-template BTF id lists file-local tracing: Use seq_buf for string concatenation tracing: Use strscpy() instead of strcpy() in trace_sched_switch tracing: Warn when an event dereferences a pointer in TP_printk() samples/ftrace: Prevent division by zero when nr_function_calls is zero tracing: Reject invalid preemptirq_delay_test CPU affinity fgraph: Use trace_seq_putc() in print_graph_return() tracing/user_events: Replace a seq_printf() call by seq_puts() in user_seq_show() tracing/user_events: Use seq_putc() in two functions tracing: Bound histogram expression strings with seq_buf tracing: Return ERR_PTR() from expr_str() tracing: Use __free() for expr_str() buffer kernel/trace/trace_printk: Use kstrdup() instead of kmalloc() and strcpy() tracing: Point constant hist field type to string literal selftests/bpf: Add test for tracepoint btf_ids tracefs file tracing: Expose tracepoint BTF ids via tracefs ...

2026-08-19nvdimm: virtio_pmem: stop allocating child flush bioLi Chen
pmem_submit_bio() passes the parent bio to nvdimm_flush() for REQ_FUA. For virtio-pmem this makes async_pmem_flush() allocate and submit a child PREFLUSH bio chained to the parent. That child allocation is in the block submit path. Making it blocking with GFP_NOIO can consume the same global bio mempool that submit_bio() uses, while making it GFP_ATOMIC can fail under pressure. A forced failure of the child allocation produced: virtio_pmem: forcing child bio allocation failure for test Buffer I/O error on dev pmem0, logical block 0, lost sync page write EXT4-fs (pmem0): I/O error while writing superblock EXT4-fs (pmem0): mount failed Avoid the child bio without turning REQ_FUA into a synchronous submit-path wait. Let provider flush callbacks return NVDIMM_FLUSH_ASYNC after taking ownership of parent bio completion. pmem_submit_bio() returns in that case, and virtio-pmem queues an ordered WQ_MEM_RECLAIM work item that runs the existing host flush path and completes the parent bio. This keeps the asynchronous completion model of the child-bio path while removing the child bio allocation from the submit path. Signed-off-by: Li Chen <me@linux.beauty> Signed-off-by: Michael S.

2026-08-19virtio: add virtio_device_shutdown() helperDenis V. Lunev
The generic virtio bus .shutdown handler, virtio_dev_shutdown(), breaks and resets a device once it has established that the driver has no .shutdown of its own. A driver that does implement .shutdown, to quiesce its own activity first, still needs the same break and reset afterwards and would otherwise have to open code it. Factor the break + synchronize_cbs + reset sequence out of virtio_dev_shutdown() into an exported virtio_device_shutdown() helper so such drivers can reuse it instead of duplicating the core logic. No functional change. Signed-off-by: Denis V. Lunev <den@openvz.org> Reviewed-by: David Hildenbrand (Arm) <david@kernel.org> Signed-off-by: Michael S.

Pull ARM SoC platform updates from Arnd Bergmann: "The 32-bit Arm platforms are a bit more interesting this time: I refreshed an earlier series to mark code as deprecated that does have the tendency of getting in the way of cleanups and new features but has close to zero users. Among these are: - 22 of the remaining 28 legacy board files that predate the current devicetree based descriptions, using old chips from Intel and Marvell. The remaining six board files are for TI OMAP1 and Samsung s3c64xx chips and all still have known users. - support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25 machines based on these. These all use devicetree but the CPU support causes disproportional work. Most of them are just reference boards, the notable exceptions being the Nokia N800/N810 tablet and the Buglabs BUG platform. - be8, be32, oabi and iwmmxt userspace binaries, which were mostly associated with the platforms now scheduled for removal and are increasingly problematic to support with modern toolchains. Nothing is actually removed at this point, to ensure that any remaining users continue to have the 7.3-LTS for a while longer. Patches for removal are currently being tested.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer and timekeeping core updates from Thomas Gleixner: - Fix a subtly inconsistency in the timekeeping code, which fails to account for the monotonicity adjustment in ntp_error. For small changes of the clocksource multiplicator (+/-1) which are typically used by the NTP PLL this is hard to observe. But for larger adjustments, e.g. caused by a direct frequency setting through adjtimex() the one-time uncompensated offset is significant. Cure this by adjusting ntp_error with the resulting offset so that the discrepancy is smoothed away over time - Make tick length calculations correct in NTP. The timekeeping core takes the quantisation of the clocksource into account when calculating the tick length to compensate for the deviation of the nominal NTP_INTERVAL_LENGTH. While timekeeping gets this right, NTP is not aware of that, which means it operates on the nominal value and not on the actual value which is determined by the clock source frequency. The rounding of a coarse clocksource like the ACPI PM timer results in a +127 PPM deviation. Cure this by exposing the deviation to the NTP code so that it can operate on the same data as the timekeeping core. This is purely kernel internal. User space still sees the nominal tick lenght via adjtimex(). - The accuracy of the NTP adjustments is fairly approximate as the code assumes that the invocations are precisely in NTP interval frequency ticks and the final adjustment can over and under-run. Cure this by adjusting ntp_error by the intended skew on each tick to achieve the desired rate. - Handle the two competing skews of time offset and time adjustment correctly by calculating the conflict portion between the skews and adjusting both accordingly. - A set of updates and improvements for the selftests - The usual small fixes and improvements all over the place * tag 'timers-core-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (58 commits) selftests: timers: nsleep-lat: Check all calls to clock_nanosleep() and clock_gettime() selftests: timers: nsleep-lat: Reuse kselftest error numbers selftests: timers: nsleep-lat: Explicitly list the tested clocks selftests: timers: nsleep-lat: Use NSEC_PER_MSEC define for unreasonable latency selftests: timers: nanosleep: Report each test separately selftests: timers: nanosleep: Explicitly handle timer_delete() failure selftests: timers: nanosleep: Move all single clock tests out of the loop in main() selftests: timers: nanosleep: Reuse kselftest error numbers selftests: timers: nanosleep: Explicitly list the tested clocks selftests: timers: nanosleep: Drop output alignment selftests: timers: Use clock_name() and constants from clock-helpers.h selftests: Add clock-helpers.h timer_list: Use ktime_t over nanoseconds timer_list: Use standard 'long long' format placeholders hrtimer: Add a lockdep assertion to hrtimer_update_base() timekeeping: Use u32 for clock_was_set_seq timekeeping: Rename clockid_aux_valid() to clockid_is_aux_clock() hrtimer: Account nr_retries on recovered interrupt retries timers/itimer: Zero-init old itimerval before copy to userspace nohz: Replace dead select with choice default ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull treewide timer related cleanups from Thomas Gleixner: - Remove the leftover CLOCK_TICK_RATE which has been scheduled for removal more than a decade ago along with some now empty asm/timex.h files. - Consolidate delay timer calibration The construct of having a define in a header requires that architectures provided asm/timex.h for no reason. Also the function name for reading the delay timer is confusing at best. Use a config switch to enable that functionality and rename the function to delay_read_timer() to make the purpose clear. This removes some more now empty asm/timex.h files as well. * tag 'timers-cleanups-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: calibrate: Rework delay timer calibration treewide: Remove CLOCK_TICK_RATE x86: Use PIT_TICK_RATE instead of CLOCK_TICK_RATE
