selftests: bonding: add a test for VLAN propagation over a bonded real device
Add a regression test for the VLAN notifier handling that the netdev_work deferral fixed. A VLAN's real device propagates its UP/DOWN, MTU and feature changes onto the VLANs stacked on top of it. This used to be done synchronously from the real device's notifier and deadlocked when the real device was brought up while enslaved to a bond (instance lock held across NETDEV_UP) and the VLAN on top was itself a bond member: the synchronous propagation re-entered the stack and took the same instance lock again. The test covers both halves: - that the deferred UP/DOWN, MTU and feature propagation actually lands on the VLAN (link state and MTU use an ops-locked dummy, i.e. the deferral path; features use veth, which exports vlan_features to inherit), and - that the deadlock-prone topology - a VLAN on a dummy, with the VLAN and the dummy each enslaved to a different bond - can be built without hanging.

selftests: tls: size splice_short pipe by page size
splice_short grows its pipe with (MAX_FRAGS + 1) * 0x1000 so it can
queue one short vmsplice() buffer for each fragment before draining the
pipe. That assumes 4K pipe buffers.
On 64K-page kernels the request is rounded to 262144 bytes, which
provides only four pipe buffers. The fifth one-byte vmsplice() blocks in
pipe_wait_writable and the test times out before it reaches the TLS path.
Request enough bytes for the same number of pipe buffers using the
runtime page size, and assert that the kernel granted at least that much.
If an unprivileged run cannot raise the pipe above the system
pipe-max-size limit, skip the test because it cannot exercise the
intended path.

The latest kernels select CONFIG_THREAD_INFO_IN_TASK, it can just read preempt_count from the thread_info which is embedded within task_struct.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Add a workaround to avoid a possible crash if nf_nat and nft_chain_nat are
compiled built-in and nf_nat fails to register, allowing nft_chain_nat to
access the incorrect pernetns area. This is crash specific of all built-in
compilation. From Matias Krause.
2) Revisit conncount GC optimization for confirmed conntracks, skip GC round
if IPS_ASSURED is set on. This is addressing an issue for corner case
use case scenario involving locally generated traffic. No crash, just a
functionality fix. From Fernando F. Mancera.
3) Validate iph->ihl in flowtable IPIP tunnel support, from Lorenzo Bianconi.
This a sanity check to bounces back malformed IPIP packets to classic
forwarding path.
4) Kdoc fixes for x_tables.h, from Randy Dunlap.
5) Use info->options so nft_synproxy_tcp_options() stays on the same local
snapshot, otherwise eval path can observe inconsistent mix of mss and
timestamps. From Runyu Xiao.
6) Add conntrack_sctp_collision.sh to cover for SCTP INIT collisions.
From Yi Chen.
7) Do not allow NFPROTO_UNSPEC targets if family is NFPROTO_BRIDGE in
nft_compat. This allows to use non-sense targets such as xt_nat leading
to crash. From Florian Westphal.
8) Add a selftest queueing from bridge family. From Florian Westphal.
9) Do not allow to reset a conntrack helper via ctnetlink. This feature
antedates the creation of the conntrack-tools, and it is not used
I don't have a usecase for it, I prefer to remove than fixing it.
10) Add deprecation warning for IPv4 only conntrack helpers for PPTP
and IRC. From Florian Westphal.
11) Store the master tuple in the expectation object and use it,
otherwise SLAB_TYPESAFE_RCU rules allow to display incorrect
master tuple information through ctnetlink.
12) Run expectation eviction when inserting an expectation with no
helper, this is a fix for the nft_ct custom expectation support.
13) Fix nft_ct custom expectation timeouts, userspace provides a
timeout in milliseconds but kernel assumes this comes in seconds.
From Florian Westphal.
14) Cap maximum number of expectations per class to 255 expectations
per master conntrack at helper registration. This is a fix to
restrict the maximum number of expectations per master conntrack
which can be a issue for the new lazy GC expectation approach.

KVM: s390: selftests: Fix cmma selftest
The existing cmma selftest depended on the host allocating page tables
for all present memslots. Since the gmap rewrite, memory that is not
accessed by the guest might not have page tables allocated yet.
This caused the test to fail due to a mismatch in the assertion.
Fix by having the guest access also the second half of the test
memslot, thus guaranteeing that its page tables are present.

selftests/xsk: restore shared_umem after POLL_TXQ_FULL
POLL_TXQ_FULL temporarily disables shared_umem on TX to exercise the TX timeout path in isolation. With shared_umem enabled, TX setup expects RX UMEM to be initialized first and fails with: "RX UMEM is not initialized before shared-UMEM TX setup". Save and restore shared_umem around POLL_TXQ_FULL execution, and restore it on both success and pkt_stream_replace() failure paths. Also add an in-code comment explaining why shared_umem is temporarily disabled in this test. This keeps timeout setup local and prevents cross-test state leakage.

selftests/xsk: fix timeout thread harness sequencing
Prevent workers from running before XDP program attachment completes. The previous ordering allowed races between worker startup and setup. Attach XDP programs before entering traffic validation. Remove SIGUSR1-based worker termination and use pthread_join() for thread shutdown so blocking syscalls are not interrupted. Use barriers only for dual-thread runs so participants match and teardown ordering stays deterministic. This removes setup/startup races and stabilizes harness sequencing.

selftests/xsk: make poll timeout mode explicit
Stop inferring timeout behavior from RX UMEM initialization state. That ties timeout semantics to setup internals and obscures intent. Use test_spec::poll_tmout as the explicit timeout-mode selector in TX and RX paths. In RX, treat poll timeout as expected only in timeout mode. In TX, let send_pkts() own loop completion in non-timeout mode and use __send_pkts() only for progress and timeout detection. This makes timeout logic explicit and keeps control flow predictable.

selftests: netfilter: conntrack_sctp_collision.sh: Introduce SCTP INIT collision test
The existing test covered a scenario where a delayed INIT_ACK chunk updates the vtag in conntrack after the association has already been established. A similar issue can occur with a delayed SCTP INIT chunk. Add a new simultaneous-open test case where the client's INIT is delayed, allowing conntrack to establish the association based on the server-initiated handshake. When the stale INIT arrives later, it may get recorded and cause a following INIT_ACK from the peer to be accepted instead of dropped. This INIT_ACK overwrites the vtag in conntrack, causing subsequent SCTP DATA chunks to be considered as invalid and then dropped by nft rules matching on ct state invalid. This test verifies such stale INIT chunks do not cause problems.

selftests: drv-net: so_txtime: relax variance bounds
The net-next-hw spinners on netdev.bots.linux.dev observe failing
so-txtime-py tests. A review of stdout shows most failures to be
due to exceeding the 4ms grace period. All I saw were within 8ms.
So increase to that.
Double the bounds from 4 to 8ms. This is still is small enough to
differentiate the delays programmed by the test, 10 and 20ms.

selftests/bpf: Add test for stale bounds on LSM retval context load
Add a verifier test that catches the stale-bounds issue fixed in the previous patch. The test sets r6 = 0 to create known bounds, then loads the LSM hook return value into r6 from the context. Without the fix, the verifier intersects the retval range with the stale bounds and incorrectly narrows r6 to a single value, pruning the fall-through branch as dead code and missing the div-by-zero.

Add a conntrack kfunc regression check for opts__sz values that do not cover opts->error. The BPF program initializes opts->error with a guard value, calls the lookup and allocation kfuncs with opts__sz set to sizeof(opts->netns_id), and verifies that the guard is still intact after the kfunc returns NULL. Without the conntrack wrapper guard, the kfunc error path overwrites that guard with -EINVAL even though the verifier checked only the first four bytes of the options object. Fixes: |

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net. This batches
fixes for real crashes with trivial/correctness fixes. There is too
a rework of the conntrack expectation timeout strategy to deal with
a possible race when removing an expectation.
1) Fix the incorrect flowtable timeout extension for entries in
hw offload, from Adrian Bente. This is correcting a defect in
the functionality, no crash.
2) Hold reference to device under the fake dst in br_netfilter,
from Haoze Xie. This is fixing a possible UaF if the device
is removed while packet is sitting in nfqueue.
3) Reject template conntrack in xt_cluster, otherwise access to
uninitialize conntrack fields are possible leading to WARN_ON
due to unset layer 3 protocol. From Wyatt Feng.
4) Make sure the IPv6 tunnel header is in the linear skb data
area before pulling. While at it remove incomplete NEXTHDR_DEST
support. From Lorenzo Bianconi. This possibly leading to crash
if IPv4 header is not in the linear area.
5) Use test_bit_acquire in ipset hash set to avoid reordering
of subsequent memory access. This is addressing a LLM related
report, no crash has been observed. From Jozsef Kadlecsik.
6) Use test_bit_acquire in ipset bitmap set too, for the same
reason as in the previous patch, from Jozsef Kadlecsik.
7) Call kfree_rcu() after rcu_assign_pointer() to address a
possible UaF if kfree_rcu() runs inmediately, which to my
understanding never happens. Never observed in practise,
reported by LLM. Also from Jozsef Kadlecsik.
8) Use disable_delayed_work_sync() instead cancel_delayed_work_sync()
to avoid that ipset GC handler re-queues work as reported by LLM.
From Jozsef Kadlecsik. This is for correctness.
9) Restore the check in nft_payload for exceeding payloda offset
over 2^16. From Florian Westphal. This fixes a silent truncation,
not a big deal, but better be assertive and reject it.
10) Validate NFT_META_BRI_IIFHWADDR can only run from bridge
prerouting. From Florian Westphal. Harmless but it could allow
to read bytes from skb->cb.
11) Zero out destination hardware address during the flowtable
path setup, also from Florian. This is a correctness fix, LLM
points that possible infoleak can happen but topology to achieve
it is not clear.
12) Skip IPv4 options if present when building the IPV4 reject reply.
Otherwise bytes in the IPv4 options header can be sent back to
origin where the ICMP header is being expected. Again from
Florian Westphal.
13) Replace timer API for expectation by GC worker approach. This
is implicitly fixing a race between nf_ct_remove_expectations()
which might fail to remove the expectation due to timer_del()
returning false because timer has expired and callback is
being run concurrently. This fix is addressing a crash that has
been already reported with a reproducer.
14) Check if br_vlan_get_pvid_rcu() fails, otherwise possible stack
infoleak of 4-bytes. From Florian Westphal.

introduce slab_alloc_context to keep function parameter bloat in

kmalloc_flags() exposes alloc_flags for mm-internal users.

selftests/bpf: Test cgroup link replace with BPF_F_PREORDER
Add a cgroup_preorder case that attaches a normal and a BPF_F_PREORDER program to a cgroup (effective order [2, 1]), then replaces the normal link's program via bpf_link_update() and checks the effective order becomes [2, 3] — i.e. only the non-preorder slot changes.

bpftool: Fix vmlinux BTF leak in cgroup commands
bpftool cgroup show and tree call libbpf_find_kernel_btf() to
resolve attach_btf names, but never release the returned BTF object.
For cgroup tree, do_show_tree_fn() is called once for each cgroup
visited by nftw(). When more than one cgroup has attached programs,
each callback overwrites btf_vmlinux with a new object and loses the
previous allocation.
Load vmlinux BTF only once during a tree walk and release it when
cgroup show or tree completes. Reset btf_vmlinux_id at the same time
so batch mode starts with clean state.

bpf: Allow type tag BTF records to succeed other modifier records
llvm commit [1] allowed attaching type tag records to modifier BTF records. This is useful for using typedefs that encompass a base type and a type tag, e.g.: typedef struct rbtree __arena rbtree_t; Modify btf_check_type_tags() so that it allows this sequence of records. The function now only checks for record loops in BTF modifier record chains. Rename to btf_check_modifier_chain_length to reflect this. Also expand the BTF modifier traversal code to take into account that type record can be interleaved with other modifier records. In effect this means traversing all modifiers to collect the type tags. Also modify existing selftests to now accept modifier records (const, typedef) that point to type tag records.

selftests/mm: fix exclusive_cow test fork() handling
The test ignores the return value of fork(), so both the parent and the
(newly created) child run the COW verification loops and then call
hmm_buffer_free() before returning into the kselftest harness, which
_exit()s each side. This duplicated teardown sequence has been observed
to manifest as a SIGSEGV in the test child, e.g.:
hmm-tests[360141]: segfault (11) at 0 nip 10006964 lr 1000ac3c code 1
in hmm-tests[6964,10000000+30000]
Fix this by adopting the same fork()-then-wait pattern already used by the
nearby anon_write_child / anon_write_child_shared tests in this file: the
child performs the COW verification and then _exit(0)s so it does not run
the test teardown, while the parent independently verifies COW, waits for
the child, and only then frees the buffer.

selftests/mm: remove hardcoded THP sizing assumptions in hmm tests
migrate_partial_unmap_fault() and migrate_remap_fault() use hardcoded offsets based on a 2MB PMD size. Similarly, benchmark_thp_migration() assumes a fixed 2MB THP size when generating test buffer sizes. Derive offsets and test sizes from the runtime PMD page size returned by read_pmd_pagesize(). If unavailable, fall back to TWOMEG. This allows the tests to adapt correctly on systems where PMD-sized THP differs from 2MB. Also replace the fixed 1MB unmap size with a PMD-relative value derived from the runtime PMD size. On systems with larger PMD sizes, computed test buffer sizes can exceed INT_MAX. Skip such test cases to avoid overflow. Link: https://lore.kernel.org/20260611034102.1030738-3-aboorvad@linux.ibm.com Fixes: |
