12 daysselftests/tc-testing: Create test cases for adding qdiscs to invalid qdisc ↵Victor Nogueira1-0/+66
parents As described in a previous commit [1], Lion's patch [2] revealed an ancient bug in the qdisc API. Whenever a user tries to add a qdisc to an invalid parent (not a class, root, or ingress qdisc), the qdisc API will detect this after qdisc_create is called. Some qdiscs (like fq_codel, pie, and sfq) call functions (on their init callback) which assume the parent is valid, so qdisc_create itself may have caused a NULL pointer dereference in such cases. This commit creates 3 TDC tests that attempt to add fq_codel, pie and sfq qdiscs to invalid parents - Attempts to add an fq_codel qdisc to an hhf qdisc parent - Attempts to add a pie qdisc to a drr qdisc parent - Attempts to add an sfq qdisc to an inexistent hfsc classid (which would belong to a valid hfsc qdisc) [1] https://lore.kernel.org/all/20250707210801.372995-1-victor@mojatatu.com/ [2] https://lore.kernel.org/netdev/d912cbd7-193b-4269-9857-525bee8bbb6a@gmail.com/ Signed-off-by: Victor Nogueira <victor@mojatatu.com> Link: https://patch.msgid.link/20250712145035.705156-1-victor@mojatatu.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

12 daysselftests: netfilter: add conntrack clash resolution test caseFlorian Westphal4-0/+337
Add a dedicated test to exercise conntrack clash resolution path. Test program emits 128 identical udp packets in parallel, then reads back replies from socat echo server. Also check (via conntrack -S) that the clash path was hit at least once. Due to the racy nature of the test its possible that despite the threaded program all packets were processed in-order or on same cpu, emit a SKIP warning in this case. Two tests are added: - one to test the simpler, non-nat case - one to exercise clash resolution where packets might have different nat transformations attached to them.

compatibility mode sys_futex_wait() expects a struct __kernel_timespec pointer for the timeout, but the provided struct timespec pointer is of type struct old_timespec32 when compiled for 32-bit architectures, unless they use 64-bit timespecs already. Make it work for all variants by converting the provided timespec value into a local struct __kernel_timespec and provide a pointer to it to the syscall. This is a pointless operation for 64-bit, but this is not a hotpath operation, so keep it simple.

2025-06-25libbpf: Fix possible use-after-free for externsAdin Scannell1-0/+16
The `name` field in `obj->externs` points into the BTF data at initial open time. However, some functions may invalidate this after opening and before loading (e.g. `bpf_map__set_value_size`), which results in pointers into freed memory and undefined behavior. The simplest solution is to simply `strdup` these strings, similar to the `essent_name`, and free them at the same time. In order to test this path, the `global_map_resize` BPF selftest is modified slightly to ensure the presence of an extern, which causes this test to fail prior to the fix. Given there isn't an obvious API or error to test against, I opted to add this to the existing test as an aspect of the resizing feature rather than duplicate the test.

Commit 869c788909b9 ("selftests: harness: Stop using setjmp()/longjmp()") changed the harness structure. For some unknown reason, two build warnings occur to the iommufd selftest: iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns’: iommufd.c:1807:17: warning: ‘mfd’ may be used uninitialized in this function 1807 | close(mfd); | ^~~~~~~~~~ iommufd.c:1767:13: note: ‘mfd’ was declared here 1767 | int mfd; | ^~~ iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns_copy’: iommufd.c:1870:17: warning: ‘mfd’ may be used uninitialized in this function 1870 | close(mfd); | ^~~~~~~~~~ iommufd.c:1819:13: note: ‘mfd’ was declared here 1819 | int mfd; | ^~~ All the mfd have been used in the variant->file path only, so it's likely a false alarm. FWIW, the commit mentioned above does not cause this, yet it might affect gcc in a certain way that resulted in the warnings. It is also found that ading a dummy setjmp (which doesn't make sense) could mute the warnings: https://lore.kernel.org/all/aEi8DV+ReF3v3Rlf@nvidia.com/ The job of this selftest is to catch kernel bug, while such warnings will unlikely disrupt its role. Mute the warning by force initializing the mfd and add an ASSERT_GT().

2025-06-24iommufd/selftest: Fix iommufd_dirty_tracking with large hugepage sizesNicolin Chen1-9/+21
The hugepage test cases of iommufd_dirty_tracking have the 64MB and 128MB coverages. Both of them are smaller than the default hugepage size 512MB, when CONFIG_PAGE_SIZE_64KB=y. However, these test cases have a variant of using huge pages, which would mmap(MAP_HUGETLB) using these smaller sizes than the system hugepag size. This results in the kernel aligning up the smaller size to 512MB. If a memory was located between the upper 64/128MB size boundary and the hugepage 512MB boundary, it would get wiped out: https://lore.kernel.org/all/aEoUhPYIAizTLADq@nvidia.com/ Given that this aligning up behavior is well documented, we have no choice but to allocate a hugepage aligned size to avoid this unintended wipe out. Instead of relying on the kernel's internal force alignment, pass the same size to posix_memalign() and map(). Also, fix the FIXTURE_TEARDOWN() misusing munmap() to free the memory from posix_memalign(), as munmap() doesn't destroy the allocator meta data. So, call free() instead.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking fixes from Borislav Petkov: - Make sure the switch to the global hash is requested always under a lock so that two threads requesting that simultaneously cannot get to inconsistent state - Reject negative NUMA nodes earlier in the futex NUMA interface handling code - Selftests fixes * tag 'locking_urgent_for_v6.16_rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: futex: Verify under the lock if hash can be replaced futex: Handle invalid node numbers supplied by user selftests/futex: Set the home_node in futex_numa_mpol selftests/futex: getopt() requires int as return value.

Pull kvm fixes from Paolo Bonzini: "ARM: - Fix another set of FP/SIMD/SVE bugs affecting NV, and plugging some missing synchronisation - A small fix for the irqbypass hook fixes, tightening the check and ensuring that we only deal with MSI for both the old and the new route entry - Rework the way the shadow LRs are addressed in a nesting configuration, plugging an embarrassing bug as well as simplifying the whole process - Add yet another fix for the dreaded arch_timer_edge_cases selftest RISC-V: - Fix the size parameter check in SBI SFENCE calls - Don't treat SBI HFENCE calls as NOPs x86 TDX: - Complete API for handling complex TDVMCALLs in userspace. This was delayed because the spec lacked a way for userspace to deny supporting these calls; the new exit code is now approved" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: TDX: Exit to userspace for GetTdVmCallInfo KVM: TDX: Handle TDG.VP.VMCALL<GetQuote> KVM: TDX: Add new TDVMCALL status code for unsupported subfuncs KVM: arm64: VHE: Centralize ISBs when returning to host KVM: arm64: Remove cpacr_clear_set() KVM: arm64: Remove ad-hoc CPTR manipulation from kvm_hyp_handle_fpsimd() KVM: arm64: Remove ad-hoc CPTR manipulation from fpsimd_sve_sync() KVM: arm64: Reorganise CPTR trap manipulation KVM: arm64: VHE: Synchronize CPTR trap deactivation KVM: arm64: VHE: Synchronize restore of host debug registers KVM: arm64: selftests: Close the GIC FD in arch_timer_edge_cases KVM: arm64: Explicitly treat routing entry type changes as changes KVM: arm64: nv: Fix tracking of shadow list registers RISC-V: KVM: Don't treat SBI HFENCE calls as NOPs RISC-V: KVM: Fix the size parameter check in SBI SFENCE calls
