2025-05-23tcp: Restrict SO_TXREHASH to TCP socket.Kuniyuki Iwashima
sk->sk_txrehash is only used for TCP. Let's restrict SO_TXREHASH to TCP to reflect this. Later, we will make sk_txrehash a part of the union for other protocol families. Note that we need to modify BPF selftest not to get/set SO_TEREHASH for non-TCP sockets.

2025-05-22selftests/mm: deduplicate second mmap() of 5*PAGE_SIZE at baseMark Brown
The map_fixed_noreplace test does two blocks of test starting from a mapping of 5 pages at the base address, logging a test result for each initial mapping. These are logged with the same test name, causing test automation software to see two reports for the same test in a single run. Tweak the log message for the second one to deduplicate.

2025-05-22selftests/mm: add simple VM_PFNMAP tests based on mmap'ing /dev/memDavid Hildenbrand
Let's test some basic functionality using /dev/mem. These tests will implicitly cover some PAT (Page Attribute Handling) handling on x86. These tests will only run when /dev/mem access to the first two pages in physical address space is possible and allowed; otherwise, the tests are skipped. On current x86-64 with PAT inside a VM, all tests pass: TAP version 13 1..6 # Starting 6 tests from 1 test cases. # RUN pfnmap.madvise_disallowed ... # OK pfnmap.madvise_disallowed ok 1 pfnmap.madvise_disallowed # RUN pfnmap.munmap_split ... # OK pfnmap.munmap_split ok 2 pfnmap.munmap_split # RUN pfnmap.mremap_fixed ... # OK pfnmap.mremap_fixed ok 3 pfnmap.mremap_fixed # RUN pfnmap.mremap_shrink ... # OK pfnmap.mremap_shrink ok 4 pfnmap.mremap_shrink # RUN pfnmap.mremap_expand ... # OK pfnmap.mremap_expand ok 5 pfnmap.mremap_expand # RUN pfnmap.fork ... # OK pfnmap.fork ok 6 pfnmap.fork # PASSED: 6 / 6 tests passed. # Totals: pass:6 fail:0 xfail:0 xpass:0 skip:0 error:0 However, we are able to trigger: [ 27.888251] x86/PAT: pfnmap:1790 freeing invalid memtype [mem 0x00000000-0x00000fff] There are probably more things worth testing in the future, such as MAP_PRIVATE handling. But this set of tests is sufficient to cover most of the things we will rework regarding PAT handling.

2025-05-22selftests: netfilter: move fib vrf test to nft_fib.shFlorian Westphal
It was located in conntrack_vrf.sh because that already had the VRF bits. Lets not add to this and move it to nft_fib.sh where this belongs. No functional changes for the subtest intended. The subtest is limited, it only covered 'fib oif' (route output interface query) when the incoming interface is part of a VRF. Next we can extend it to cover 'fib type' for VRFs and also check fib results when there is an unrelated VRF in same netns.

2025-05-22selftests: netfilter: nft_fib.sh: add 'type' mode testsFlorian Westphal
fib can either lookup the interface id/name of the output interface that would be used for the given address, or it can check for the type of the address according to the fib, e.g. local, unicast, multicast and so on. This can be used to e.g. make a locally configured address only reachable through its interface. Example: given eth0:10.1.1.1 and eth1:10.1.2.1 then 'fib daddr type' for 10.1.1.1 arriving on eth1 will be 'local', but 'fib daddr . iif type' is expected to return 'unicast', whereas 'fib daddr' and 'fib daddr . iif' are expected to indicate 'local' if such a packet arrives on eth0. So far nft_fib.sh only covered oif/oifname, not type. Repeat tests both with default and a policy (ip rule) based setup. Also try to run all remaining tests even if a subtest has failed.

2025-05-22selftests: netfilter: nft_concat_range.sh: add coverage for 4bit group ↵Florian Westphal
representation Pipapo supports a more compact '4 bit group' format that is chosen when the memory needed for the default exceeds a threshold (2mb). Add coverage for those code paths, the existing tests use small sets that are handled by the default representation. This comes with a test script run-time increase, but I think its ok: normal: 2m35s -> 3m9s debug: 3m24s -> 5m29s (with KSFT_MACHINE_SLOW=yes).

2025-05-22selftests/tc-testing: Add an HFSC qlen accounting testCong Wang
This test reproduces a scenario where HFSC queue length and backlog accounting can become inconsistent when a peek operation triggers a dequeue and possible drop before the parent qdisc updates its counters. The test sets up a DRR root qdisc with an HFSC class, netem, and blackhole children, and uses Scapy to inject a packet. It helps to verify that HFSC correctly tracks qlen and backlog even when packets are dropped during peek-induced dequeue.

If $CANIF is omitted or if it starts with vcan (e.g. vcan1), the test will use the virtual can interface type. Otherwise, it will assume that the provided interface is a physical can interface.

2025-05-21selftests: can: Import tst-filter from can-testsFelix Maurer
Tests for the can subsystem have been in the can-tests repository[1] so far. Start moving the tests to kernel selftests by importing the current tst-filter test. The test is now named test_raw_filter and is substantially updated to be more aligned with the kernel selftests, follow the coding style, and simplify the validation of received CAN frames. We also include documentation of the test design. The test verifies that the single filters on raw CAN sockets work as expected. We intend to import more tests from can-tests and add additional test cases in the future. The goal of moving the CAN selftests into the tree is to align the tests more closely with the kernel, improve testing of CAN in general, and to simplify running the tests automatically in the various kernel CI systems.

2025-05-21selftests: harness: Stop using setjmp()/longjmp()Thomas Weißschuh
Usage of longjmp() was added to ensure that teardown is always run in commit 63e6b2a42342 ("selftests/harness: Run TEARDOWN for ASSERT failures") However instead of calling longjmp() to the teardown handler it is easier to just call the teardown handler directly from __bail(). Any potential duplicate teardown invocations are harmless as the actual handler will only ever be executed once since commit fff37bd32c76 ("selftests/harness: Fix fixture teardown"). Additionally this removes a incompatibility with nolibc, which does not support setjmp()/longjmp().
