2026-04-12selftests/bpf: Add test for cgroup storage OOB readLang Xu
Add a test case to reproduce the out-of-bounds read issue when copying from a cgroup storage map to a pcpu map with a value_size not rounded up to 8 bytes. The test creates: 1. A CGROUP_STORAGE map with 4-byte value (not 8-byte aligned) 2. A LRU_PERCPU_HASH map with 4-byte value (same size) When a socket is created in the cgroup, the BPF program triggers bpf_map_update_elem() which calls copy_map_value_long(). This function rounds up the copy size to 8 bytes, but the cgroup storage buffer is only 4 bytes, causing an OOB read (before the fix).

2026-04-12selftests/bpf: Fix reg_bounds to match new tnum-based refinementPaul Chaignon
Commit efc11a667878 ("bpf: Improve bounds when tnum has a single possible value") improved the bounds refinement to detect when the tnum and u64 range overlap in a single value (and the bounds can thus be set to that value). Eduard then noticed that it broke the slow-mode reg_bounds selftests because they don't have an equivalent logic and are therefore unable to refine the bounds as much as the verifier. The following test case illustrates this. ACTUAL TRUE1: scalar(u64=0xffffffff00000000,u32=0,s64=0xffffffff00000000,s32=0) EXPECTED TRUE1: scalar(u64=[0xfffffffe00000001; 0xffffffff00000000],u32=0,s64=[0xfffffffe00000001; 0xffffffff00000000],s32=0) [...] #323/1007 reg_bounds_gen_consts_s64_s32/(s64)[0xfffffffe00000001; 0xffffffff00000000] (s32)<op> S64_MIN:FAIL with the verifier logs: [...] 19: w0 = w6 ; R0=scalar(smin=0,smax=umax=0xffffffff, var_off=(0x0; 0xffffffff)) R6=scalar(smin=0xfffffffe00000001,smax=0xffffffff00000000, umin=0xfffffffe00000001,umax=0xffffffff00000000, var_off=(0xfffffffe00000000; 0x1ffffffff)) 20: w0 = w7 ; R0=0 R7=0x8000000000000000 21: if w6 == w7 goto pc+3 [...] from 21 to 25: [...] 25: w0 = w6 ; R0=0 R6=0xffffffff00000000 ; ^ ; unexpected refined value 26: w0 = w7 ; R0=0 R7=0x8000000000000000 27: exit When w6 == w7 is true, the verifier can deduce that the R6's tnum is equal to (0xfffffffe00000000; 0x100000000) and then use that information to refine the bounds: the tnum only overlap with the u64 range in 0xffffffff00000000. The reg_bounds selftest doesn't know about tnums and therefore fails to perform the same refinement. This issue happens when the tnum carries information that cannot be represented in the ranges, as otherwise the selftest could reach the same refined value using just the ranges. The tnum thus needs to represent non-contiguous values (ex., R6's tnum above, after the condition). The only way this can happen in the reg_bounds selftest is at the boundary between the 32 and 64bit ranges. We therefore only need to handle that case. This patch fixes the selftest refinement logic by checking if the u32 and u64 ranges overlap in a single value. If so, the ranges can be set to that value. We need to handle two cases: either they overlap in umin64... u64 values matching u32 range: xxx xxx xxx xxx |--------------------------------------| u64 range: 0 xxxxx UMAX64 or in umax64: u64 values matching u32 range: xxx xxx xxx xxx |--------------------------------------| u64 range: 0 xxxxx UMAX64 To detect the first case, we decrease umax64 to the maximum value that matches the u32 range. If that happens to be umin64, then umin64 is the only overlap. We proceed similarly for the second case, increasing umin64 to the minimum value that matches the u32 range. Note this is similar to how the verifier handles the general case using tnum, but we don't need to care about a single-value overlap in the middle of the range. That case is not possible when comparing two ranges. This patch also adds two test cases reproducing this bug as part of the normal test runs (without SLOW_TESTS=1).

2026-04-12selftests/bpf: Add tests for sock_ops ctx access with same src/dst registerJiayuan Chen
Add selftests to verify SOCK_OPS_GET_SK() and SOCK_OPS_GET_FIELD() correctly return NULL/zero when dst_reg == src_reg and is_fullsock == 0. Three subtests are included: - get_sk: ctx->sk with same src/dst register (SOCK_OPS_GET_SK) - get_field: ctx->snd_cwnd with same src/dst register (SOCK_OPS_GET_FIELD) - get_sk_diff_reg: ctx->sk with different src/dst register (baseline) Each BPF program uses inline asm (__naked) to force specific register allocation, reads is_fullsock first, then loads the field using the same (or different) register. The test triggers TCP_NEW_SYN_RECV via a TCP handshake and checks that the result is NULL/zero when is_fullsock == 0.

2026-04-12selftests: net: py: add test case filtering and listingJakub Kicinski
When developing new test cases and reproducing failures in existing ones we currently have to run the entire test which can take minutes to finish. Add command line options for test selection, modeled after kselftest_harness.h: -l list tests (filtered, if filters were specified) -t name include test -T name exclude test Since we don't have as clean separation into fixture / variant / test as kselftest_harness this is not really a 1 to 1 match. We have to lean on glob patterns instead. Like in kselftest_harness filters are evaluated in order, first match wins. If only exclusions are specified everything else is included and vice versa. Glob patterns (*, ?, [) are supported in addition to exact matching.

Impose global ordering for all decl tags used by test_loader.c based tests (__success, __failure, __msg, etc): - change every tag to expand as __attribute__((btf_decl_tag("comment:" XSTR(__COUNTER__) ...))) - change parse_test_spec() to collect all decl tags before processing and sort them using strverscmp(). The ordering is necessary for gcc-bpf. Neither GCC nor the C standard defines the order in which function attributes are consumed. While Clang tends to preserve definition order, GCC may process them out of sequence. This inconsistency causes BPF tests with multiple __msg entries to fail when compiled with GCC.

2026-04-10selftests: net: add bridge STP mode selection testAndy Roulin
Add a selftest for the IFLA_BR_STP_MODE bridge attribute that verifies: 1. stp_mode defaults to auto on new bridges 2. stp_mode can be toggled between user, kernel, and auto 3. Changing stp_mode while STP is active is rejected with -EBUSY 4. Re-setting the same stp_mode while STP is active succeeds 5. stp_mode user in a network namespace yields userspace STP (stp_state=2) 6. stp_mode kernel forces kernel STP (stp_state=1) 7. stp_mode auto in a netns preserves traditional fallback to kernel STP 8. stp_mode and stp_state can be set atomically in a single message 9. stp_mode persists across STP disable/enable cycles Test 5 is the key use case: it demonstrates that userspace STP can now be enabled in non-init network namespaces by setting stp_mode to user before enabling STP. Test 8 verifies the atomic usage pattern where both attributes are set in a single netlink message, which is supported because br_changelink() processes IFLA_BR_STP_MODE before IFLA_BR_STP_STATE. The test gracefully skips if the installed iproute2 does not support the stp_mode attribute.

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.

2026-04-09selftests: Add MACsec VLAN propagation traffic testCosmin Ratiu
Add VLAN filter propagation tests through offloaded MACsec devices via actual traffic. The tests create MACsec tunnels with matching SAs on both endpoints, stack VLANs on top, and verify connectivity with ping. Covered: - Offloaded MACsec with VLAN (filters propagate to HW) - Software MACsec with VLAN (no HW filter propagation) - Offload on/off toggle and verifying traffic still works On netdevsim this makes use of the VLAN filter debugfs file to actually validate that filters are applied/removed correctly. On real hardware the traffic should validate actual VLAN filter propagation.

As some real hardware requires MACsec to use encryption, add that to the tests. Netdevsim-specific limit checks (max SecY, max RX SC) were moved into separate test cases to avoid failures on real hardware.

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>

Add extensive selftests for netkit queue leasing, using io_uring zero copy test binary inside of a netns with netkit. 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.

Report an error for './runner foo' (positional arg instead of -t) and for './runner -t foo' when the filter matches no tests. Previously both cases produced no error output. Pre-scan the test list before the main loop so the error is reported immediately, avoiding spurious SKIP output from '-s' when no tests match.

2026-04-08selftests/bpf: Add test to ensure kprobe_multi is not sleepableVarun R Mallya
Add a selftest to ensure that kprobe_multi programs cannot be attached using the BPF_F_SLEEPABLE flag. This test succeeds when the kernel rejects attachment of kprobe_multi when the BPF_F_SLEEPABLE flag is set.

2026-04-08selftests: pci_endpoint: Skip BAR subrange test on -ENOSPCChristian Bruel
In pci-epf-test.c, set the STATUS_NO_RESOURCE status bit if pci_epc_set_bar() returns -ENOSPC. This status bit is used to indicate that there are not enough inbound window resources to allocate the subrange. In pci_endpoint_test.c, return -ENOSPC instead of -EIO when STATUS_NO_RESOURCE is set. In pci_endpoint_test.c, skip the BAR subrange test if -ENOSPC, i.e., there are not enough inbound window resources to run the test.
