2026-07-09mm: page_reporting: allow driver to set batch capacityMichael S. Tsirkin1-1/+3
At the moment, if a virtio balloon device has a page reporting vq but its size is < PAGE_REPORTING_CAPACITY (32), the balloon driver fails probe. But, there's no way for host to know this value, so it can easily create a smaller vq and suddenly adding the reporting capability to the device makes all of the driver fail. Not pretty. Add a capacity field to page_reporting_dev_info so drivers can control the maximum number of pages per report batch. In virtio-balloon, set the capacity to the reporting virtqueue size, letting page_reporting adapt to whatever the device provides. Capacity need not be a power of two. Code previously called out division by PAGE_REPORTING_CAPACITY as cheap since it was a power of 2, but no performance difference was observed with non-power-of-2 values. If capacity is 0 or exceeds PAGE_REPORTING_CAPACITY, it defaults to PAGE_REPORTING_CAPACITY. The 0 check and the clamping is done in page_reporting_register(), before the reporting work is scheduled, so we never get division by 0.

2026-07-09remoteproc: qcom_q6v5_pas: Switch over to generic PAS TZ APIsSumit Garg1-3/+3
Switch qcom_q6v5_pas client driver over to generic PAS TZ APIs. Generic PAS TZ service allows to support multiple TZ implementation backends like QTEE based SCM PAS service, OP-TEE based PAS service and any further future TZ backend service. Since qcom_q6v5_pas depends on MDT loader for PAS firmware loading, it has to be switched over to generic PAS APIs in this commit to avoid any build issues.

2026-07-09firmware: qcom: Add a generic PAS serviceSumit Garg1-0/+43
Qcom platforms has the legacy of using non-standard SCM calls splintered over the various kernel drivers. These SCM calls aren't compliant with the standard SMC calling conventions which is a prerequisite to enable migration to the FF-A specifications from Arm. OP-TEE as an alternative trusted OS to Qualcomm TEE (QTEE) can't support these non-standard SCM calls. And even for newer architectures using S-EL2 with Hafnium support, QTEE won't be able to support SCM calls either with FF-A requirements coming in. And with both OP-TEE and QTEE drivers well integrated in the TEE subsystem, it makes further sense to reuse the TEE bus client drivers infrastructure. The added benefit of TEE bus infrastructure is that there is support for discoverable/enumerable services. With that client drivers don't have to manually invoke a special SCM call to know the service status. So enable the generic Peripheral Authentication Service (PAS) provided by the firmware. It acts as the common layer with different TZ backends plugged in whether it's an SCM implementation or a proper TEE bus based PAS service implementation.

This prevents a dangerous runtime fallback to the interpreter for features that are only implemented in the JIT compiler. Currently, bpf_prog_has_kfunc_call() is used only for kernel function calls, replace the kfunc-specific helper with the new 'jit_required' flag.

In the "vCPU locked or unreachable" lockdep assertion, treat a vCPU as unreachable if its index is invalid, i.e. if the vCPU is in the process of being created. Until the vCPU is inserted into the array of vCPUs, the only way to get at the vCPU is via kvm_vm_ioctl_create_vcpu(). Note, the actual index is set _before_ adding the vCPU to the array, i.e. there's no risk of a false negative on the lockdep assertion.

2026-07-08SUNRPC: pin upper rpc_clnt across the TLS connect_workerChuck Lever1-0/+1
The TLS connect path has a use-after-free: nothing pins the upper rpc_clnt across the delayed connect_worker. xs_connect() stores task->tk_client in sock_xprt::clnt as a raw pointer and queues the worker; for TLS-secured transports that worker is xs_tcp_tls_setup_socket(), which reads several fields out of the saved pointer (cl_timeout, cl_program, cl_prog, cl_vers, cl_cred, cl_stats) to construct the args for the inner handshake rpc_clnt. The xprt does not reference the rpc_clnt; the rpc_clnt references the xprt. xs_destroy() does cancel the connect_worker, but it runs only when the xprt's refcount drops to zero, which cannot happen until the rpc_clnt releases its cl_xprt reference in rpc_free_client_work(). When a TLS handshake fails fatally (for example, an mTLS mount whose client cert does not match the server), the connecting task is woken with -EACCES and exits, the mount caller invokes rpc_shutdown_client(), and the upper rpc_clnt is freed before the queued connect_worker fires. xs_tcp_tls_setup_socket() then dereferences the freed clnt, producing the refcount_t underflow Michael Nemanov reported. Take a reference on the upper rpc_clnt in xs_connect() for TLS transports via a new rpc_hold_client() helper, and drop it in the connect_worker's exit path with rpc_release_client(). The xprt_lock_connect() / xprt_unlock_connect() pairing already serialises xs_connect() with xs_tcp_tls_setup_socket(), so the take and release are balanced one-for-one. The non-TLS connect worker (xs_tcp_setup_socket) never reads sock_xprt::clnt, so leave that path alone and avoid the clnt-holds-xprt-holds-clnt cycle that would otherwise prevent xprt destruction.

2026-07-08libbpf: Drop in-loader metadata check for load-time verificationDaniel Borkmann1-1/+0
The signed gen_loader used to police its own metadata map from within BPF: emit_signature_match() read the kernel-cached map->sha[] back through hardcoded struct bpf_map offsets and compared it against a hash that compute_sha_update_offsets() baked into the signed instructions, after a BPF_OBJ_GET_INFO_BY_FD round-trip to populate map->sha[]. The kernel now verifies the metadata at BPF_PROG_LOAD time by folding the frozen contents of the loader's exclusive fd_array maps into the signature, so the loader no longer checks anything itself. Generated loaders thus carry no verification logic of their own anymore: Nothing in the signing chain depends on emitted loader bytecode doing the right thing. On the loading side, skel_internal.h now sets fd_array_cnt for a signed load so the kernel scans fd_array for the exclusive metadata map - still frozen, as the kernel requires - and the BPF_OBJ_GET_INFO_BY_FD round-trip to populate map->sha[] is gone. The struct bpf_map layout BUILD_BUG_ON()s on the kernel side are removed as well: they only pinned the ABI for the in-BPF read of map->sha[] that is no longer needed. Same for the map->excl member. Note: gen_hash is retained; it still marks a loader as signed so an untrusted host cannot re-dimension maps or override initial values now covered by the signature.

2026-07-08bpf: Verify signed loader metadata at load timeDaniel Borkmann1-0/+1
A signed gen_loader program carries the programs, maps and relocations it installs in a metadata array map. The loader instructions are covered by the PKCS#7 signature, but the metadata map is not: Today the loader compares the map contents from within BPF against a hash baked into its (signed) instructions, using the kernel-cached map hash. The kernel itself never actually attests that the metadata the loader installs is the metadata that was signed. This split is the core of the long-standing objection to the BPF signing scheme from the LSM / integrity side: the integrity check of a light skeleton only completes once the loader program runs, that is, after the security_bpf_prog_load() hook, so at admission time an LSM observes a program whose payload has not yet been verified. Auditing the chain link is also not a purely cryptographic operation: whoever signs or reviews an lskel has to disassemble the loader's preamble to convince themselves that the embedded hash check is present and correct [0][1]. Two acceptable fixes were identified in those threads: Complete the integrity check before the admission hook fires, or add a second hook that collects the verification result after the loader ran [2]. Covering both the loader and its maps directly with the PKCS#7 signature is what Blaise Boscaccy's patchsets proposed in several forms. Let's implement the former, without growing the UAPI, and in particular as a single unified scheme where the signature spans the raw bytes rather than derived hashes. A signed loader binds its metadata map(s) through the existing fd_array, and an exclusive map is already bound to a program digest (excl_prog_hash). So when a signature is present, collect the exclusive maps from fd_array and append their frozen contents to the instructions before verification: The signature now covers insns || metadata_0 || metadata_1 || [...] in the fd_array order, and verification completes in bpf_check(), once the fd_array maps are resolved into used_maps, before the LSM admission hook and the rest of verification. A program is either BPF_SIG_UNSIGNED or BPF_SIG_VERIFIED, with nothing in between. While folding the fd_array maps, a non-exclusive map bound to a signed program is rejected, so every map folded into the signature is exclusive. A signed loader that fails to cover its metadata thus does not load, and BPF_SIG_VERIFIED always means the instructions and every exclusive map are authentic. The maps must be frozen so the hashed bytes cannot change before the loader runs; the map <-> program digest binding is enforced by the verifier for every used map. Binding maps through fd_array_cnt makes the verifier resolve and excl-check them (excl_prog_sha vs prog->digest) before it would otherwise compute the digest, so compute prog->digest up front in bpf_check(), over the unmodified instructions the signature covers, for a load that folds metadata. Unsigned programs are not affected by the signature path; for them the LSM admission hook merely moves below fd_array resolution, with minimal bounded work in between. Note, signed loaders generated by older libbpf/ bpftool versions need to be regenerated; some of the recent fixes we've had on the signed loader side require the latter already to close gaps. Finally, some remarks around the security_bpf_prog_load() placement given there was discussion on whether a new hook is needed or the existing security_bpf_prog() hook should be reused [3]: For a new hook it would mean that just for loading a single BPF program it has to pass through four layers of LSM hooks: 1) security_bpf (cmd=PROG_LOAD): for gating various bpf subcmds 2) security_bpf_prog_load: historical admission hook (CAP/token, prog_type, attach point), pre-verification 3) security_bpf_prog_verify_signature: newly asked admission hook, same role as 2), plus the BPF signature verdict 4) security_bpf_prog: gate handing the prog fd back to userspace, verification done & signature verified The use-cases of 2) and 3) conflate, thus BPF community prefers to just keep a total of 3 LSM hooks (as-is today): 3) makes 2) incoherent given they are the /same class/ of hook, that is, access-control admission on the load and split only by _what_ they can see. Worse, with the split, for a signed BPF program security_bpf_prog_load 2) admits a program whose signature has not been checked, so a policy gating at 2) is structurally unable to express "admit only verified" and every such policy is forced onto 3) *anyway*. In other words, one doesn't get two complementary hooks, but rather, one real admission hook aka 3) plus a now-degraded /legacy/ hook 2) that can't answer the question operators actually want to ask. Reusing security_bpf_prog() 4) for admission is no alternative either: it fires only after the entire verifier (and JIT) pipeline ran, so denying a not-yet-verified program at that point burns exactly the work a denial is supposed to avoid, and by then the program has an id assigned and the kallsyms/perf/audit load events fired. Policies are free to also consume the signature verdict at 4), but admission control belongs into security_bpf_prog_load(). Hence the latter remains the only admission hook, merely moved past signature verification; with moving large allocations further down into the BPF verifier, there is now only minimal work between the old and new location: The preparation work in bpf_check() is reordered such that only the minimally necessary setup happens up front: Allocating the env, initializing the verifier log and resolving the fd_array that a signed BPF metadata map needs. The worst case allocation up until security_bpf_prog_load() is ~90K which is the env itself (~54K) plus the continuous fd_array cache (at most 32K). The insn_aux_data array is moved into a later stage in the verification.

The fd_array passed to BPF_PROG_LOAD carries the map and module BTF file descriptors a program binds. The verifier reads it more than once during a load: process_fd_array() walks it to bind the maps and BTFs, and check_and_resolve_insns() and the kfunc BTF resolver later read it again to resolve the program's BPF_PSEUDO_MAP_IDX* and module kfunc refs. For signed BPF, we need these upfront in memory, thus resolve each fd to its object once and cache it by fd_array index, then bind that cached object for the rest of the load. env->fd_array becomes a small per-slot {map, btf} cache rather than a bpfptr_t; every later reference is then an in-bounds lookup of an already-resolved object, and an index outside the cache is rejected instead of read from user memory: - continuous (fd_array_cnt given): the caller declares the length and every entry is resolved and bound up front (used also by the BPF signed loader) - sparse (no fd_array_cnt): left as the legacy path with no fd_array cache; each reference reads its fd from the caller's fd_array and resolves it on the spot. Deduplication in used_maps and the kfunc BTF table keeps this correct, and only unsigned programs use this shape. Split these into separate helpers to make it easier to follow.

2026-07-08ipv4: igmp: Fix potential UAF in igmp_gq_start_timer()Eric Dumazet1-0/+5
A race condition exists between device teardown (inetdev_destroy) and incoming IGMP query processing (igmp_rcv), leading to a Use-After-Free in the IGMP timer callback. During device destruction, inetdev_destroy() drops the primary reference to in_device, which can drop its refcount to 0. The actual freeing of in_device memory is deferred via RCU (using call_rcu()). Concurrently, igmp_rcv() runs under RCU read lock and obtains the in_device pointer. Because the memory is RCU-protected, CPU-0 can safely dereference in_device even if its refcount has hit 0. However, if CPU-0 calls igmp_gq_start_timer() and re-arms the timer, it attempts to acquire a reference using in_dev_hold(). This increments the refcount from 0 to 1, triggering a "refcount_t: addition on 0" warning. Since the in_device memory is still scheduled to be freed after the RCU grace period (as the free callback does not check the refcount again), the device is freed while the timer is still armed. When the timer expires, it accesses the freed memory, causing a kernel panic. Fix this by using refcount_inc_not_zero() (via a new helper in_dev_hold_safe()) to prevent acquiring a reference if the device is already being destroyed. If the refcount is 0, we do not arm the timer. A similar issue in IPv6 MLD is fixed in a subsequent patch.

2026-07-07genirq: Remove unnecessary NULL check of the kstat_irqs fieldRadu Rendec1-1/+1
The kstat_irqs field of struct irq_desc is used to store a per-cpu count of interrupt events. It is initialized in init_desc(), along with all the other fields in struct irq_desc that need explicit initialization, and therefore it's always available (non-NULL) for any valid interrupt descriptor (with a caveat - see below). When CONFIG_SPARSE_IRQ is enabled, all interrupt descriptors are always allocated dynamically via alloc_desc(), which calls init_desc(), so in that case kstat_irqs is guaranteed to be non-NULL before a valid struct irq_desc pointer is even returned. By contrast, when CONFIG_SPARSE_IRQ is disabled, interrupt descriptors are allocated statically in the irq_desc[] array, and kstat_irqs is initialized implicitly to NULL. The per-cpu pointer is initialized only later, for all descriptors, via start_kernel() -> early_irq_init() -> init_desc(). The kstat_irqs field is used mostly for printing interrupt statistics (i.e. reading /proc/interrupts), and that cannot happen until much later, when user-space is fully initialized. So, there is no concern with that use case. The list below includes all functions where the NULL check is removed, along with a list of all possible call chains and/or a brief explanation of why it's safe to remove the NULL check in that case. * irq_desc_kstat_cpu() [include/linux/irqdesc.h] - All direct call sites use it for printing IRQ statistics. - Indirect call site: per_cpu_count_show() - also used for printing interruptstatistics. * kstat_irqs_cpu() [kernel/irq/irqdesc.c] - Called by sun3_int7() and sun3_int5() [arch/m68k/sun3/sun3ints.c] These are interrupt handlers and cannot be called until their corresponding interrupts are initialized in sun3_init_IRQ(). The call chain leading to that is: start_kernel() -> init_IRQ() [arch/m68k/kernel/ints.c] -> mach_init_IRQ = sun3_init_IRQ() The init_IRQ() call happens right *after* the early_irq_init() call, which means the descriptors are already fully initialized by the time the interrupt handlers are even registered. - Called by show_interrupts() [arch/s390/kernel/irq.c] - used for printing interrupt statistics. * kstat_irqs() [kernel/irq/irqdesc.c] The only possible call chain is via fs/proc/stat.c: stat_open() -> show_stat() -> show_all_irqs() -> kstat_irqs_usr() -> kstat_irqs() It is used for printing interrupt statistics. * kstat_snapshot_irqs() The only possible call chain is via kernel/watchdog.c: watchdog_timer_fn() -> is_softlockup() -> start_counting_irqs() -> kstat_snapshot_irqs() The watchdog timer cannot fire early, before early_irq_init(). * kstat_get_irq_since_snapshot() The only possible call chain is via kernel/watchdog.c: watchdog_timer_fn() -> report_cpu_status() -> print_irq_counts() -> kstat_get_irq_since_snapshot() The watchdog timer cannot fire early, before early_irq_init().

2026-07-07tracing: Add a no-rcu-check version of trace_##event##_enabled()Steven Rostedt1-1/+11
Tracepoints require that RCU is watching. To prevent them from being used in places that RCU is not watching, the trace_##event() macro always calls rcu_is_watching() even when the event is not enabled and warns if RCU is not watching. This is to make sure a warning is triggered even if the tracepoint is never enabled (as it is only a bug when it is). It was noticed that tracepoints could be hidden within trace_#event#_enabled() calls, which are used to do extra work for the tracepoint only if the tracepoint is enabled. But this also can hide the fact that a tracepoint is placed in a location that can be called when RCU is not watching. Commit 9764e731ef6ab ("tracepoint: Add lockdep rcu_is_watching() check to trace_##name##_enabled()") added a check to the trace_##event##_enabled() macro to make sure RCU is watching when it is called to make sure not to hide the bug of a tracepoint being called when RCU is not watching. There is one case in the irq_disable tracepoint where it is within a trace_irq_disable_enabled() block, but it checks if RCU is watching, and if it isn't, it makes a call to ct_irq_enter() that makes RCU watch again. But because trace_irq_disable_enabled() now checks if RCU is watching and will trigger if it isn't. This is a false warning as the code within the block handles this case. Add a new internal macro __trace_##event##_enabled() that doesn't check if RCU is watching, and convert the irq_enable/disable tracepoints over to it.

2026-07-07tracing: Prevent out-of-bounds read in glob matchingHuihui Huang1-0/+1
String event fields are not necessarily NUL-terminated, so the filter predicate functions (filter_pred_string(), filter_pred_strloc() and filter_pred_strrelloc()) pass the field length to the regex match callbacks, and the length-aware matchers honour it. regex_match_glob() was the exception: it ignored the length and called glob_match(), which scans the string until it hits a NUL byte. Some string fields are not NUL-terminated. One example is the dynamic char array of the xfs_* namespace tracepoints, which is copied without a trailing NUL. For such a field, glob matching reads past the end of the event field, causing a KASAN slab-out-of-bounds read in glob_match(), reached via regex_match_glob() and filter_match_preds() from the xfs_lookup tracepoint. Add a length-bounded glob_match_len() and use it from regex_match_glob() so glob matching always stops at the field boundary. The matching loop is factored into a shared helper so glob_match() keeps its behaviour.

x86 asm/setup.h includes linux/kexec_handover.h. This is because it is used by setup.c and kaslr.c. But this inclusion is problematic. The header is included in many places, so it results in the KHO header being propagated there. Also, the setup header is used by realmode code. If KHO header includes things like mm.h, it causes a big dump of compilation failures. Nothing in setup.h uses anything from KHO. Remove the header from setup.h, and directly include it in setup.c. which does use things from KHO. Since kaslr.c is a part of the decompressor, avoid including linux headers there directly. Instead, split out struct kho_scratch, which is the only thing the kaslr.c uses, and move it to include/asm-generic/kexec_handover.h.
