Building the rseq selftests against musl libc fails because musl's <features.h> does not provide the glibc-specific __GNUC_PREREQ macro: error: missing binary operator before token '(' Replace __GNUC_PREREQ(11, 1) with an equivalent check using __GNUC__ and __GNUC_MINOR__ directly. This pattern is portable across all C library implementations and is already used elsewhere in the tools/ tree (e.g., tools/include/linux/string.h).

2026-07-01selftests/bpf: Fix test_maps sockmap failureJiayuan Chen
test_maps fails in the sockmap test because sockmap_verdict_prog.c drops the packet when the first 8 bytes are not directly accessible: if (data + 8 > data_end) return SK_DROP; The blamed commit removed bpf_skb_pull_data() from the stream parser program so that the parser no longer modifies the skb. That was needed, but it also removed an implicit side effect: bpf_skb_pull_data() linearized enough of the skb for later direct packet access. In this test, the send side goes through the sockmap SK_MSG path. The skb can have skb->len == 20 while its linear area is empty, so the verdict program sees data == data_end and drops the packet even though the payload length is sufficient. Keep the parser read-only, and pull the first 8 bytes in the verdict program before reading or writing them. Reload data/data_end after bpf_skb_pull_data() as required.

2026-07-01selftests/bpf: Mask socket type flags in mptcpify progGuillaume Maudoux
The mptcpify BPF prog upgrades eligible TCP sockets to MPTCP, but only when the socket type is exactly SOCK_STREAM. Its update_socket_protocol() hook runs on the raw type from userspace, before the socket core masks it with SOCK_TYPE_MASK, so the type may still carry SOCK_CLOEXEC or SOCK_NONBLOCK in its upper bits and the equality check fails. As a result, a socket(AF_INET, SOCK_STREAM | SOCK_CLOEXEC, 0) -- what common libraries do by default -- is silently left as plain TCP. This was hit in practice with curl. Since mptcpify.c is referenced as example code for enabling MPTCP transparently, the same mistake is likely to be copied into real deployments where it fails the same way and is hard to diagnose. Mask the type before comparing, mirroring the socket core. Extend the test to also create the server with SOCK_CLOEXEC set; the same masking is applied to start_server_addr() so a flagged type still listens.

2026-07-01selftests/hid: multitouch: test a large ContactCountMaximumTrung Nguyen
Add a regression test for the out-of-bounds bit operations on struct mt_device.mt_io_flags. A HID multitouch device can advertise a ContactCountMaximum far larger than the number of contacts a single report describes, up to 255. The driver used to keep the per-slot active state in the bits of a single unsigned long and index set_bit()/clear_bit() by the slot number, so such a device drove those operations out of bounds. The sticky-fingers release timer made it fatal: mt_release_contacts() cleared one bit per slot and overwrote the adjacent members of struct mt_device. The new device advertises a ContactCountMaximum of 250 while exposing only a few finger collections (a large contact count cannot be expressed with one finger collection per contact within the HID descriptor size limit). The test sends a single contact and lets the 100ms sticky-fingers timer release it. A kernel without the fix panics in mt_release_contacts(); a fixed kernel reports the release cleanly.

2026-07-01selftests/filesystems: test O_TMPFILE creation on idmapped mountsChristian Brauner
Add a regression test for the fsuidgid_has_mapping() check in vfs_tmpfile(). It idmaps a detached tmpfs mount so that the caller-visible id range [0, 10000) maps onto the on-disk range [10000, 20000) and checks that: - a caller whose fsuid/fsgid fall outside that range cannot create an O_TMPFILE through the mount and gets -EOVERFLOW instead of an inode owned by (uid_t)-1; - a mapped caller can create an O_TMPFILE, link it into the namespace, and the ownership round-trips through the mount idmap: it is reported as 0 through the mount and stored as 10000 on the underlying tmpfs. The test runs entirely as root and uses setfsuid()/setfsgid() to become the unmapped caller, so it needs no helper user. The layer directory is world-writable so that an unmapped caller still clears the directory permission check and reaches the fsuidgid_has_mapping() test.

2026-07-01selftests/hid: Cover hid_bpf_get_data() size overflowYiyang Chen
Add a HID-BPF regression check for hid_bpf_get_data() requests whose size would overflow when added to the offset. The new rdesc fixup callback asks for offset 2 and size ~0ULL, then records whether the helper returns NULL. A vulnerable kernel returns a non-NULL pointer because the runtime check wraps the addition. A fixed kernel rejects the request. The callback records the helper result without dereferencing any returned pointer. The callback reports the helper result through BSS and returns 0 intentionally. hid_rdesc_fixup return values are consumed as report descriptor fixup results, so a positive test-result value would be interpreted as a replacement report descriptor size. Also add KHDR_INCLUDES to the HID selftest build so hid_bpf.c sees the current kernel UAPI HID definitions on systems whose installed headers do not provide enum hid_report_type.

2026-06-30selftests/xsk: Preserve UMEM view in BIDIRECTIONAL testMaciej Fijalkowski
The UMEM state refactor made __send_pkts() use xsk->umem for Tx address generation. At the same time, the shared-UMEM Tx setup copies the Rx UMEM state into a Tx-local state object and resets base_addr and next_buffer before configuring the Tx socket. Passing that Tx-local object to xsk_configure() makes xsk->umem point to the zero-based Tx allocator state. This breaks the BIDIRECTIONAL test once the roles are switched: the same socket is then used for Rx validation, but received descriptors from the other logical UMEM half are checked against base_addr == 0. With the new UMEM bounds check, a valid address such as base_addr + XDP_PACKET_HEADROOM is rejected as being outside the UMEM window. Keep xsk->umem as the shared/Rx UMEM view used for socket configuration and Rx validation. Use the ifobject-local UMEM copy only for Tx descriptor address generation, preserving the BIDIRECTIONAL test's intent of using the proper logical UMEM half after the direction switch.

2026-06-30selftests: net: bump default cmd() timeout to 20 secondsJakub Kicinski
We always used 5 sec as the default command timeout. But soon after it was introduced, David effectively made us ignore the timeout (it was passed to process.communicate() as the wrong argument). Gal recently fixed that, but turns out the 5 sec is not enough for a lot of tests and setups. The fix caused regressions. In particular running reconfig commands (e.g. XDP attach) on mlx5 with 32 rings and 9k MTU, on a heavily-debug-enabled kernel takes more than 5 sec. The XDP installation command will time out after 5 sec but since the sleeps in the kernel are non interruptible the command finishes anyway, leaving the XDP program attached, but with non-zero exit code. defer()ed cleanups are not installed, breaking the environment for subsequent tests. Since "install XDP" is a pretty normal command a "point fix" does not seem appropriate. 32 rings is a fairly reasonable config, too, so we should just increase the timeout to 20 sec. There's no real reason behind the value of 20.

It applies an idmapping to a freshly created (still detached) overlay mount with mount_setattr(MOUNT_ATTR_IDMAP) and checks that: - getattr reports ownership mapped through the mount idmap; - a file created through the idmapped mount is stored on the upper layer with the corresponding overlay-final id; - chown through the idmapped mount round-trips; - an nfs_export overlay can be idmapped and decodable file handles round-trip through it with correctly mapped ownership. The layers live on a private tmpfs and are owned by the host id so that they map to id 0 through the test idmapping, allowing the root caller to operate on them.

2026-06-25selftests/bpf: Fix resolve_btfids test reads of BTF ID sets in PIE buildsIhor Solodrai
TL;DR On aarch64 with gcc toolchain, when test_progs is linked as a PIE, reads of BTF ID array by C name return garbage because the GNU assembler on aarch64 unconditionally folds .local symbol references into section+addend form, and GOT slots cannot carry an addend per the AArch64 ELF spec. Fix by marking the test's BTF ID objects with hidden visibility, which makes gcc emit a direct access that bypasses the GOT entirely. Details below. The subsequent patches adding kfunc checks to resolve_btfids test may cause test failures on aarch64 / gcc-15: test_resolve_btfids:FAIL:kfunc_set_flags actual 13 != expected 1 test_resolve_btfids:FAIL:kfunc_set_cnt actual 0 != expected 4 The test defines its BTF ID sets with the same macros as the kernel and reads them back directly by C name (in the same way as the kernel code does). test_kfunc_set is a .local symbol emitted into .BTF_ids by inline asm and declared to the compiler as a plain default-visibility extern, that is: extern struct btf_id_set8 test_kfunc_set; Depending on the build environment, test_progs may be linked as a position-independent executable (for example, gcc defaults to -fpie [1]). In a PIE, taking the address of a default-visibility extern is routed through the GOT (Global Offset Table) [2]. The GNU assembler's adjust_reloc_syms() pass (gas/write.c [3]) replaces references to local symbols with the corresponding section symbol, folding the symbol's offset into the relocation addend. On aarch64 this conversion is unconditional: tc_fix_adjustable() is defined to 1 for all fixups (gas/config/tc-aarch64.h [4]), so even GOT-generating relocations are subject to it. The resulting object file therefore contains: R_AARCH64_ADR_GOT_PAGE .BTF_ids + 0x54 R_AARCH64_LD64_GOT_LO12_NC .BTF_ids + 0x54 However, the AArch64 ELF specification mandates that GOT-generating relocations must have a zero addend [5]. The +0x54 is therefore not honored: the linker creates a GOT slot pointing at the .BTF_ids base, and every access through that slot reads offset 0 instead of 0x54. This is purely a read-side problem, specific to the PIE test binary on aarch64 with gcc toolchain. resolve_btfids patches the set header correctly and the .BTF_ids bytes in test_progs are correct. vmlinux is unaffected because it is built with -fno-PIE [6] and reaches .BTF_ids with direct, addend-preserving relocations rather than the GOT. clang is unaffected because LLVM's assembler retains the original symbol for GOT relocations instead of converting to section+addend [7]. To mitigate this issue, mark the test's .local BTF ID objects (test_list_local and test_set) hidden with a visibility pragma so that gcc treats them as non-interposable and emits a direct access instead of a GOT load. test_list_global is .globl, which the assembler does not fold into section+addend, so it is left at default visibility. This keeps the natural by-name access, works in both PIE and non-PIE builds, and needs no change to the BTF_ID macros or resolve_btfids.
