2026-04-10bpf: poison dead stack slotsAlexei Starovoitov
As a sanity check poison stack slots that stack liveness determined to be dead, so that any read from such slots will cause program rejection. If stack liveness logic is incorrect the poison can cause valid program to be rejected, but it also will prevent unsafe program to be accepted. Allow global subprogs "read" poisoned stack slots. The static stack liveness determined that subprog doesn't read certain stack slots, but sizeof(arg_type) based global subprog validation isn't accurate enough to know which slots will actually be read by the callee, so it needs to check full sizeof(arg_type) at the caller.

2026-04-10selftests/bpf: adjust verifier_log buffersAlexei Starovoitov
The new liveness analysis in liveness.c adds verbose output at BPF_LOG_LEVEL2, making the verifier log for good_prog exceed the 1024-byte reference buffer. When the reference is truncated in fixed mode, the rolling mode captures the actual tail of the full log, which doesn't match the truncated reference. The fix is to increase the buffer sizes in the test.

2026-04-10selftests/bpf: Remove test_access_variable_arrayVenkat Rao Bagalkote
test_access_variable_array relied on accessing struct sched_domain::span to validate variable-length array handling via BTF. Recent scheduler refactoring removed or hid this field, causing the test to fail to build. Given that this test depends on internal scheduler structures that are subject to refactoring, and equivalent variable-length array coverage already exists via bpf_testmod-based tests, remove test_access_variable_array entirely.

2026-04-10perf arm_spe: Improve SIMD flags settingLeo Yan
Fill in ASE and SME operations for the SIMD arch field. Also set the predicate flags for SVE and SME, but differences between them: SME does not have a predicate flag, so the setting is based on events.

2026-04-10tools/power turbostat: Allow execution to continue after perf_l2_init() failureDavid Arcari
Currently, if perf_l2_init() fails turbostat exits after issuing the following error (which was encountered on AlderLake): turbostat: perf_l2_init(cpu0, 0x0, 0xff24) REFS: Invalid argument This occurs because perf_l2_init() calls err(). However, the code has been written in such a manner that it is able to perform cleanup and continue. Therefore, this issue can be addressed by changing the appropriate calls to err() to warnx(). Additionally, correct the PMU type arguments passed to the warning strings in the ecore and lcore blocks so the logs accurately reflect the failing counter type.

2026-04-09Merge branch 'netkit-support-for-io_uring-zero-copy-and-af_xdp'Jakub Kicinski
Daniel Borkmann says: ==================== netkit: Support for io_uring zero-copy and AF_XDP Containers use virtual netdevs to route traffic from a physical netdev in the host namespace. They do not have access to the physical netdev in the host and thus can't use memory providers or AF_XDP that require reconfiguring/restarting queues in the physical netdev. This patchset adds the concept of queue leasing to virtual netdevs that allow containers to use memory providers and AF_XDP at native speed. Leased queues are bound to a real queue in a physical netdev and act as a proxy. Memory providers and AF_XDP operations take an ifindex and queue id, so containers would pass in an ifindex for a virtual netdev and a queue id of a leased queue, which then gets proxied to the underlying real queue. We have implemented support for this concept in netkit and tested the latter against Nvidia ConnectX-6 (mlx5) as well as Broadcom BCM957504 (bnxt_en) 100G NICs. For more details see the individual patches. ==================== Link: https://patch.msgid.link/20260402231031.447597-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

This checks that memory providers can be bound against virtual queues in a netkit within a netns that are leasing from a physical netdev in the default netns. Also add various test cases around corner cases for the queue creation itself as well as queue info dumping and teardown in case of netkit in device pair and single mode.

2026-04-09net: Add queue-create operationDaniel Borkmann
Add a ynl netdev family operation called queue-create that creates a new queue on a netdevice: name: queue-create attribute-set: queue flags: [admin-perm] do: request: attributes: - ifindex - type - lease reply: &queue-create-op attributes: - id This is a generic operation such that it can be extended for various use cases in future. Right now it is mandatory to specify ifindex, the queue type which is enforced to rx and a lease. The newly created queue id is returned to the caller. A queue from a virtual device can have a lease which refers to another queue from a physical device. This is useful for memory providers and AF_XDP operations which take an ifindex and queue id to allow applications to bind against virtual devices in containers. The lease couples both queues together and allows to proxy the operations from a virtual device in a container to the physical device. In future, the nested lease attribute can be lifted and made optional for other use-cases such as dynamic queue creation for physical netdevs. The lack of lease and the specification of the physical device as an ifindex will imply that we need a real queue to be allocated. Similarly, the queue type enforcement to rx can then be lifted as well to support tx. An early implementation had only driver-specific integration [0], but in order for other virtual devices to reuse, it makes sense to have this as a generic API in core net. For leasing queues, the virtual netdev must have real_num_rx_queues less than num_rx_queues at the time of calling queue-create. The queue-type must be rx as only rx queues are supported for leasing for now. We also enforce that the queue-create ifindex must point to a virtual device, and that the nested lease attribute's ifindex must point to a physical device. The nested lease attribute set contains a netns-id attribute which is optional and can specify a netns-id relative to the caller's netns. It requires cap_net_admin and if the netns-id attribute is not specified, the lease ifindex will be retrieved from the current netns. Also, it is modeled as an s32 type similarly as done elsewhere in the stack.

Extend the PMU test suite to cover overflow interrupts. The test enables the PMI (Performance Monitor Interrupt), sets counter 0 to one less than the overflow value, and verifies that an interrupt is raised when the counter overflows. A guest interrupt handler checks the interrupt cause and disables further PMU interrupts upon success.

2026-04-08perf tools: Make more global variables staticIan Rogers
`make check` will run sparse on the perf code base. A frequent warning is "warning: symbol '...' was not declared. Should it be static?" Go through and make global definitions without declarations static. In some cases it is deliberate due to dlsym accessing the symbol, this change doesn't clean up the missing declarations for perf test suites. Sometimes things can opportunistically be made const. Making somethings static exposed unused functions warnings, so restructuring of ifdefs was necessary for that. These changes reduce the size of the perf binary by 568 bytes. Committer notes: Refreshed the patch, the original one fell thru the cracks, updated the size reduction. Remove the trace-event-scripting.c changes, break the build, noticed with container builds and with sashiko: https://sashiko.dev/#/patchset/20260401215306.2152898-1-acme%40kernel.org Also make two variables static to address another sashiko review comment: https://sashiko.dev/#/patchset/20260402001740.2220481-1-acme%40kernel.org Signed-off-by: Ian Rogers <irogers@google.com> Acked-by: Ankur Arora <ankur.a.arora@oracle.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Albert Ou <aou@eecs.berkeley.edu> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexandre Ghiti <alex@ghiti.fr> Cc: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Cc: Guo Ren <guoren@kernel.org> Cc: Howard Chu <howardchu95@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: James Clark <james.clark@linaro.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Leo Yan <leo.yan@arm.com> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Palmer Dabbelt <palmer@dabbelt.com> Cc: Paul Walmsley <pjw@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Yujie Liu <yujie.liu@intel.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org>
