2026-07-30selftests/mm: move pkey selftest helpers to pkey_util.cHongfu Li
Patch series "selftests/mm: refactor pkey helpers and fix mmap error handling", v10. The main changes in this series are to refactor shared tracing and assertion helpers into a common file, unify both pkey selftests on pkey_assert() and per-test tracing for consistent diagnostics, and add missing mmap() return checks with MAP_FAILED used throughout for readability and consistency. This patch (of 10): Move pkey selftest debugging helpers into shared code so both pkey selftests can use the same tracing and abort-hook logic. Also fix cat_into_file() to print file, not str, in the open() failure message.

2026-07-30selftests: net: add coverage for fdb nexthop dst_portJack Ma
Add coverage for the new per-nexthop VXLAN destination port (NHA_DST_PORT). In fib_nexthops.sh, new ipv4_fdb_port_fcnal() and ipv6_fdb_port_fcnal() tests check that a dst_port is accepted on an fdb nexthop that has a gateway and echoed back on dump, that it is rejected without a gateway and rejected when zero, that a group may hold legs that differ only in UDP port, and that a portless fdb nexthop omits the attribute. The tests SKIP when iproute2 lacks the "dst_port" keyword. In test_vxlan_nh.sh, basic_tx_common() gains a second fdb nexthop group whose nexthop carries a destination port that differs from the VXLAN device default, plus a flower filter keyed on that port, to confirm the per-nexthop port is used on the wire. The test now requires an iproute2 with dst_port support.

2026-07-30resolve_btfids: Enforce consistent kfunc flags across BTF ID setsIhor Solodrai
A kfunc may be listed in several BTF ID sets, which is expected because different kfuncs are available to BPF programs depending on their type. However kfunc flags across different BTF ID sets must be consistent [1]. The flags should be considered a part of the kfunc declaration, because they influence its BTF representation and verifier handling. Enforce the kfunc flag consistency in resolve_btifds by hard failing on error and blocking kernel (or module) build.

2026-07-30resolve_btfids: Discover kfuncs from BTF ID setsIhor Solodrai
collect_kfuncs() currently uses bpf_kfunc decl tags to identify the list of kfuncs. The decl tags are generated by pahole, which makes current implementation implicitly rely on those tags being generated. The authoritative source, used by the the BPF verifier for kfunc registration, of functions being BPF kfuncs are BTF_KFUNCS_START()/END() declarations. These are BTF_ID_SET8 under the hood. Currently resolve_btfids reads kfunc flags from these sets, and populates them with BTF IDs. Implement kfunc discovery from BTF_ID_SET8 symbols in resolve_btfids, removing the dependency on pahole's emmission of decl tags. Walk BTF_ID_KIND_SET8 sets, and use the address-to-symbol index to look up set entry's BTF_ID symbol name (before .BTF_ids is patched), recording the paired flags directly. This makes find_kfunc_flags() helper unnecessary, so it's removed.

process_kfunc_with_implicit_args() skips generating <name>_impl function when one already exists for backwards compatibility. It uses btf__find_by_name_kind(), which searches the base BTF before the split BTF.

2026-07-29KVM: selftests: Trigger L2->L1 exits stress save+restore and #PF testYosry Ahmed
Extend the testing coverage in L2 by forcing a nested VM-Exit from L2 to L1 right after restore on every other iteration. Forcing a nested VM-Exit while L0 has control (e.g. without explicitly running L2 and making a hypercall) is valuable, as it often happens during live migration (e.g. L1 timer interrupt fires by the time the VM lands on the destination). To force the nested VM-Exit inject a #UD in to the saved vCPU state, and intercept #UD from L1. With this change, the test reliably reproduces the CR2 bug fixed by commit 5c247d08bc81 ("KVM: nSVM: Use vcpu->arch.cr2 when updating vmcb12 on nested #VMEXIT") -- at least on Milan, Genoa, and Turin CPUs.

Instead of an explicit GUEST_SYNC() after each access+#PF, run another thread that keeps sending SIGUSR to the vCPU thread, essentially triggering exits to userspace and save+restore on random points in guest execution. This makes the test a lot more meaningful as it opens the door to exercising race conditions between #PF handling in the guest and save+restore in the host. The signals are ignored using SIG_IGN outside of __vcpu_run() to avoid interrupting other ioctls/sysctls performed by the test.

Add a basic stress test for handling #PFs in a guest while the host is doing save+restore cycles. The guest periodically accesses non-present memory causing a #PF, and the #PF handler walks the page tables and updates the PTE to be present, like a proper #PF handler. After every access (and #PF), the guest triggers a sync and the test performs save+restore of the VM. This is not very meaningful as save+restore are performed after the access and #PF handling complete, but following changes will change that.

2026-07-29KVM: selftests: Do not intercept #PF by default in nVMX testsYosry Ahmed
init_vmcs_control_fields() sets PFEC_MASK and PFEC_MATCH so that they never match, which reverses the meaning of the PF_VECTOR bit in EXCEPTION_BITMAP (which is zeroed), effectively enabling #PF interception by default. The relevant part of the SDM describes this: When a page fault occurs, a processor consults (1) bit 14 of the exception bitmap; (2) the error code produced with the page fault [PFEC]; (3) the page-fault error-code mask field [PFEC_MASK]; and (4) the page-fault error-code match field [PFEC_MATCH]. It checks if PFEC & PFEC_MASK = PFEC_MATCH. If there is equality, the specification of bit 14 in the exception bitmap is followed (for example, a VM exit occurs if that bit is set). If there is inequality, the meaning of that bit is reversed (for example, a VM exit occurs if that bit is clear). Clear PFEC_MATCH such that there is equality, and the #PF bit in the exception bitmap is followed, so that #PFs are not intercepted by default, same as every other exception. This also allows tests to set the #PF bit in the exception bitmap if they want to intercept #PFs, without having to muck with the PFEC_{MASK,MATCH} fields.

2026-07-29KVM: selftests: Expose PTE masks to guests as part of an MMUYosry Ahmed
Expose a guest_mmu to the guest to allow guest code to use the PTE masks for page table manipulation. Since guest page tables are not mapped in the guest by default, zero the PGD in guest_mmu in an attempt to make it more difficult for new tests to shoot themselves in the foot and assume that page tables can be immediately used by guest code. Ultimately, guest code can read CR3 any way, so guest_mmu.pgd doesn't add a lot of value.

2026-07-29KVM: selftests: Reuse GPR switching logic for nVMXYosry Ahmed
Reuse the GPR switching logic for nVMX by defining VMX_SWITCH_GPRS_ASM, which is essentially the same as SVM_SWITCH_GPRS_ASM but also switches RAX and doesn't switch RFLAGS, replacing the push/pop of a subset of the registers. The long clobber list of registers is no longer needed as registers are saved and restored appropriately (and not clobbered by L2). Define VMX_SWITCH_GPRS_ASM before including evmcs.h, such that it can be used by evmcs_vmlaunch() and evmcs_vmresume(). This replaces the apparently thread-safe push/pop sequence with the global GPR switching logic used by SVM, which isn't thread-safe at all. However this is still an improvement because: - The VMX logic is half-baked and prompts the UCALL clobber hack as it doesn't properly save/restore everything. Reusing the GPR switching logic used by SVM allows for dropping that hack. - Hitting a problem due to half-baked GPR save/restore logic is arguably more likely than thread-safety. Evidently, adding more involved stress tests fails on VMX with the existing push/pop sequence. OTOH, there are no known failures on SVM due to lack of thread-safety fo save/restore. Only one test currently uses more than one vCPU with nested (the memstress test). The logical next step is to move the guest_regs to be per-vCPU, making it thread-safe for both VMX and SVM in a proper way.

2026-07-29KVM: selftests: Rework GPR registers switching for SVM (and fix offsets)Yosry Ahmed
The assembly code defined by SAVE_GPR_C uses the wrong offsets for some registers in guest_regs. For example, the offset of RCX should be 0x08 not 0x10. Also, the last offset in the struct (R15) is 0x78, not 0x80, so the code actually saves and restore beyond the end of gpr64_regs. Eliminate hardcoded offsets by dynamically generating offsets using offset_of() and using macros to pass the offsets to assembly as asm constraints. To avoid register conflicts in inline assembly (since almost all GPRs are context-switched), access guest_regs via absolute symbol addressing (guest_regs + offset) rather than using a base register which could get overwritten mid-assembly. While at it, rename SAVE_GPR_C and LOAD_GPR_C to a single macro, SVM_SWITCH_GPRS_ASM, rename gpr64_regs to guest_regs, and expose it in processor.h (in preparation for reusing it for VMX).

2026-07-29KVM: selftests: Fix RAX and RFLAGS VMCB offsets when running L2Yosry Ahmed
The offsets used (0x170 and 0x1f8) are offsets within vmcb_save_area, not vmcb. The correct offsets should include the base of vmcb_save_area within vmcb (which is 0x400 -- so 0x570 and 0x5f8). Instead of just correcting the offsets, use vmcb->save.rax and vmcb->save.rflags as parameters to the asm block and avoid hardcoding offsets completely. While at it, also use guest_regs.rax directly instead of assuming it's at offset 0 of guest_regs. Note: "+m" must be used for vmcb_rax and vmcb_rflags, as caching those fields in registers would be wrong as the underlying KVM will update them in memory. The same problem was recently fixed (differently) for kvm-unit-tests [1].

2026-07-28selftests/damon/sysfs_refresh: test kdamond refresh_msRuslan Valiyev
Writing a non-zero value to a kdamond's 'refresh_ms' sysfs file should make DAMON periodically update the read-only sysfs files on its own, without the user writing update keywords such as 'update_schemes_stats' to the 'state' file. This behavior has no test coverage. Add a test that starts a kdamond with refresh_ms set and a 'stat' scheme whose default access pattern matches every monitored region, then polls the scheme's 'nr_tried' stats file directly, without requesting an update. The value can become non-zero only via the periodic refresh, so the test confirms refresh_ms works; with refresh_ms disabled the stat stays zero and the test fails.

2026-07-28selftests/damon/_damon_sysfs: support kdamond refresh_msRuslan Valiyev
Patch series "selftests/damon: test kdamond refresh_ms", v2. The kdamond 'refresh_ms' sysfs file makes DAMON periodically update its read-only sysfs files (DAMOS stats, tuned monitoring intervals and the kdamond pid) on its own, so users don't have to write update keywords such as 'update_schemes_stats' to the 'state' file. It has no selftest coverage. The first patch adds refresh_ms support to the _damon_sysfs.py test control module. The second adds a test that sets refresh_ms and confirms a scheme's stats are updated under sysfs without an explicit update request; the test skips on kernels that predate the refresh_ms file. Tested on current mainline under a DAMON-enabled kernel: the new test passes and the existing DAMON selftests show no new failures. This patch (of 2): The Kdamond class has no way to set the kdamond-level 'refresh_ms' sysfs file, which makes DAMON periodically update the read-only sysfs files (DAMOS stats, tuned monitoring intervals and the kdamond pid) on its own. Add a 'refresh_ms' parameter to Kdamond. When it is set (including to zero, to disable the periodic update), write it before turning the kdamond on, so tests can exercise the auto-update behavior. Leaving it unset keeps the previous behavior of not touching the file, so callers running against kernels without the feature are unaffected.

Patch 3 fixes several wrong strings that produce dead elif branches, skipped file existence checks, and broken dict key lookups. This patch (of 3): DamonCtx.__init__() uses mutable default values for monitoring_attrs, targets, and schemes. In Python these are evaluated once at function definition time, so multiple DamonCtx instances can unintentionally share the same lists and DamonAttrs instance.

This is another occurrence of using getline where the code assumes that getline allocates memory to store the line, but the pointer passed to it is uninitialized and potentially a non-null pointer. This violates the Open Group Spec[1] and caused a segfault in a similar situation in selftest/clone3/clone3_set_tid. Fix it by initializing the line pointer to NULL. The issue has been found by simply grepping through the selftest code after running into the issue in clone3_set_tid. Whether it segfaults in its current state is unknown to me.

2026-07-28selftests/clone3: fix wild pointer access of getline due to missing initChris Gellermann
Patch series "selftests: Add missing initalization of pointer passed to getline", v2. This patch (of 2): Clone3_set_tid uses getline(&line, ...) in a loop to read the child's process status. The code expects that getline allocates the buffer for the line on the first loop iteration. According to the Open Group Spec[1], char *line has to be null pointer for this: > ssize_t getline(char **restrict lineptr, ...); > If *lineptr is a null pointer or if the object pointed to by *lineptr > is of insufficient size, an object shall be allocated as if by malloc() > or the object shall be reallocated as if by realloc()[...]. However, char *line is only declared, leading to an undefined value that is potentially non-null. In an example run with Musl v1.2.6, the realloc call[2] of getdelim, which implements getline, triggers a segfault: ./run_kselftest.sh --test clone3:clone3_set_tid [ 1366.165898] kselftest: Running tests in clone3 ...
