48c3876a6a docs: submitting-patches: Clarify that "reviewer" is a person
Common understanding of word "Reviewer" is: a person performing a review
work [1]. Tools are not persons, thus cannot be reviewers in this term.
Also tools cannot make statements and cannot take responsibility for the
review.

Our docs already clearly mark that "Reviewed-by" must come from a
person:

 - "By offering my Reviewed-by: tag, I state that:"

   Usage of first person "I" and word "state"

 - "A Reviewed-by tag is *a statement of opinion* that the patch is an
    appropriate modification of the kernel without any remaining serious"

   Only a person can make a statement of opinion.

 - "Any interested reviewer (who has done the work) can offer a
   Reviewed-by"

   A person can offer a tag thus above does not grant the tool
   permission to offer a tag.

However this might not be enough, so let's clarify that only a person
with a known identity can state the "Reviewer's statement of oversight".

1. No need to an unlikely() because IS_ERR() already has an unlikely()
   built in.
2. No need to use PTR_ERR_OR_ZERO() because it's not an error pointer.
3. Use the returned error code directly instead of using groveling in

2156a29aec octeontx2-af: validate body pcifunc in rvu_mbox_handler_rep_event_notify
rvu_mbox_handler_rep_event_notify() in drivers/net/ethernet/marvell/
octeontx2/af/rvu_rep.c queues a sender-controlled REP_EVENT_NOTIFY
request body verbatim, and rvu_rep_up_notify() then forwards
event->pcifunc (the nested body field, distinct from the
AF-normalised header pcifunc) into rvu_get_pfvf(), rvu_get_pf() and
the AF->PF mailbox device index without any bounds check.

A VF attached to a PF that has been put into switchdev
representor mode reaches this path: the VF mailbox handler
otx2_pfvf_mbox_handler() forwards every message id including
MBOX_MSG_REP_EVENT_NOTIFY to AF without an allowlist, and the AF
dispatcher rewrites only msg->pcifunc, leaving struct
rep_event::pcifunc attacker-controlled.  The sibling
rvu_mbox_handler_esw_cfg() refuses requests whose header pcifunc
is not rvu->rep_pcifunc; this handler has no equivalent gate.

An out-of-range body pcifunc selects an &rvu->pf[]/&rvu->hwvf[]
element past the allocated array and, for RVU_EVENT_MAC_ADDR_CHANGE,
turns into a six-byte attacker-chosen OOB ether_addr_copy() target
inside the queued worker; KASAN reports a slab-out-of-bounds write
in rvu_rep_wq_handler.

Reject malformed requests at the handler entry by gating on
is_pf_func_valid(), which is already the canonical PF/VF range check
in this driver; expose it via rvu.h so callers in rvu_rep.c can use
it instead of open-coding the same range arithmetic.

bd2a5be1fe perf test: Add stat metrics --for-each-cgroup test
Add a new shell test `stat_metrics_cgrp.sh` to verify metric reporting
with `--for-each-cgroup`, both with and without `--bpf-counters`.

The test:
- Checks if system-wide monitoring is supported (skips if not).
- Finds cgroups to test.
- Runs `perf stat` with `insn_per_cycle` metric and verifies that the
  metric is reported for each cgroup.
- Dynamically pairs and verifies instructions and cycles counts to
  avoid false failures on idle cgroups.
- Tests both standard mode and BPF counters mode (if supported).

65bd18199a perf stat: Propagate supported flag to follower cgroup BPF events
When using BPF counters with cgroups, follower events (for cgroups
other than the first one) are not opened. Because they are not opened,
their `supported` flag was left as `false`.

During metric calculation, `prepare_metric` checks if the event is
supported. If it is not supported (like the follower events), it
explicitly sets the value to `NAN`, which eventually causes the metric
to be reported as `nan %`.

Fix this by propagating the `supported` flag from the "leader" events
(the ones opened for the first cgroup) to the "follower" events.

Also add a validation check to `bperf_load_program` to ensure `nr_cgroups`
is not zero and the number of events is a multiple of `nr_cgroups`,
preventing a potential division-by-zero (SIGFPE) exception when
`num_events` evaluates to 0 (e.g., with a trailing comma in cgroups list).

abdc2516f1 sched_ext: Convert ops.set_cmask() to arena-resident cmask
ops_cid.set_cmask() expects a cmask. The kernel couldn't write into the
arena, so it translated cpumask -> cmask in kernel memory and passed the
result as a trusted pointer. The BPF cmask helpers all operate on arena
cmasks though, so the BPF side had to word-by-word probe-read the kernel
cmask into an arena cmask via cmask_copy_from_kernel() before any helper
could touch it. It works, but is clumsy.

With direct kernel-side arena access now in place, build the cmask in the
arena. The kernel writes to it through the kern_va side of the dual mapping.
BPF directly dereferences it via an __arena pointer like any other arena
struct.

9eca087deb sched_ext: Sub-allocator over kernel-claimed BPF arena pages
Build a per-scheduler sub-allocator on top of pages claimed from the BPF
arena registered in the previous patch. Subsequent kernel-managed
arena-resident structures (e.g. per-CPU set_cmask cmask) carve their storage
from this pool.

scx_arena_pool_init() creates a gen_pool. scx_arena_alloc() returns the
kernel VA. On exhaustion, the pool grows by claiming more pages via
bpf_arena_alloc_pages_sleepable(). Chunks are added at the kernel-side
mapping address. Callers translate to the BPF-arena form themselves if
needed.

Allocations sleep (GFP_KERNEL) - they may grow the pool through vzalloc and
arena page allocation. All current consumers run from the enable path (after
ops.init() and the kernel-side arena auto-discovery, before validate_ops()),
where sleeping is fine.

scx_arena_pool_destroy() walks each chunk, returns outstanding ranges to the
gen_pool with gen_pool_free() and then calls gen_pool_destroy(). The
underlying arena pages are released when the arena map itself is torn down,
so the pool destroy doesn't free them explicitly.

0e2819cba9 sched_ext: Require an arena for cid-form schedulers
Upcoming patches will let the kernel place arena-resident scratch shared
with the BPF program (e.g. per-CPU set_cmask cmask) so the BPF side can
dereference it directly via __arena pointers, replacing the current
cmask_copy_from_kernel() probe-read loop. That requires each cid-form
scheduler to expose its arena to the kernel. Kernel- side accesses are
recovered by the per-arena scratch-page mechanism.

bpf_scx_reg_cid() walks the struct_ops member progs via
bpf_struct_ops_for_each_prog() and reads each prog's arena via
bpf_prog_arena(). The verifier enforces one arena per program, so each
member prog contributes at most one arena. All non-NULL contributions must
match and at least one member prog must use an arena. The map ref is held on
scx_sched and dropped on sched destroy. cpu-form schedulers (bpf_scx_reg)
are unchanged - no arena requirement.

e68842b335 macsec: fix replay protection at XPN lower-PN wrap
In macsec_post_decrypt(), when pn is U32_MAX, pn + 1 overflows u32 to 0
and the first branch never fires. If next_pn_halves.lower is also in the
upper half, pn_same_half(pn, lower) is true and the XPN else-if does not
fire either, leaving next_pn_halves unchanged. An attacker that captures
the legitimate frame carrying pn == 0xFFFFFFFF on an XPN association
can then replay it indefinitely, since lowest_pn never rises above
the captured pn and macsec_decrypt() reconstructs the same IV.

Extend the XPN else-if to also fire when pn + 1 wraps to 0, so receipt
of pn == U32_MAX advances next_pn_halves to (upper + 1, 0).

c96a5209dd rds: filter RDS_INFO_* getsockopt by caller's netns
The RDS_INFO_* family of getsockopt(2) options reads several
file-scope global lists that are not per-netns:

  rds_sock_info / rds6_sock_info,
  rds_sock_inc_info / rds6_sock_inc_info        -> rds_sock_list
  rds_tcp_tc_info / rds6_tcp_tc_info            -> rds_tcp_tc_list
  rds_conn_info / rds6_conn_info,
  rds_conn_message_info_cmn (for the *_SEND_MESSAGES and
  *_RETRANS_MESSAGES variants),
  rds_for_each_conn_info (for RDS_INFO_IB_CONNECTIONS)
                                                -> rds_conn_hash[]

The handlers do not filter by the caller's network namespace.
rds_info_getsockopt() has no netns or capable() check, and
rds_create() has no capable() check, so AF_RDS is reachable from
an unprivileged user namespace. As a result, an unprivileged
caller in a fresh user_ns plus netns can read the bound address
and sock inode of every RDS socket on the host, the peer address
of incoming messages on every RDS socket on the host, the peer
address and TCP sequence numbers of every rds-tcp connection on
the host, and the peer address and RDS sequence numbers of every
RDS connection on the host.

The rds-tcp transport is reachable from a non-initial netns (see
rds_set_transport()), so a one-shot init_net gate at
rds_info_getsockopt() would deny legitimate per-netns visibility
to rds-tcp callers. Instead, filter at each handler by comparing
the netns of the caller's socket to the netns of the list entry,
or to rds_conn_net(conn) for connection paths. Only copy entries
whose netns matches the caller. Counters (RDS_INFO_COUNTERS) are
aggregate statistics and remain global.

Reproducer (KASAN VM, rds and rds_tcp loaded): an AF_RDS socket
binds 127.0.0.1:4242 in init_net as root. A child process enters
a fresh user_ns plus netns and opens AF_RDS there, then calls
getsockopt(SOL_RDS, RDS_INFO_SOCKETS). Before this change, the
child sees the init_net socket. After this change, the child
sees zero entries.

Drop the rds_sock_count, rds_tcp_tc_count, and rds6_tcp_tc_count
globals. v2 used them for the size precheck and lens->nr; v3
replaced the precheck with a per-ns count from a first pass over
the list, so the globals have no remaining readers. The matching
increments and decrements in rds_create()/rds_destroy_sock() and
rds_tcp_set_callbacks()/rds_tcp_restore_callbacks() go away with
them. Reported by the kernel test robot under clang W=1.

2b413fc689 netfilter: nf_conntrack_ftp: avoid u16 overflows
get_port and try_number() parse comma-separated decimal values from FTP PORT
and EPRT commands into a u_int32_t array, but does not validate that each
value fits in a single octet. RFC 959 specifies that PORT parameters
are decimal integers in the range 0-255, representing the four octets
of an IP address followed by two octets encoding the port number.

Values exceeding 255 are silently accepted. In try_rfc959(), the raw
u32 values are combined via shift-and-OR to form the IP and port:

  cmd->u3.ip = htonl((array[0] << 24) | (array[1] << 16) |
                     (array[2] << 8) | array[3]);
  cmd->u.tcp.port = htons((array[4] << 8) | array[5]);

When array elements exceed 255, bits from one field bleed into adjacent
fields after shifting, producing IP addresses and port numbers that
differ from what the text representation suggests. For example,
"PORT 10,0,1,2,256,22" yields port (256<<8)|22 = 65558, truncated to
u16 = 22. This mismatch between the textual and computed values can
confuse network monitoring tools that parse FTP commands independently.

Ignore the command by returning 0 (no match) when any accumulated
value exceeds 255 so that no expectation is created.

netfilter: updates for net

Patches 7+8 fix a regression from 7.1-rc1. Everything else
is from 2.6.x to 5.3 releases.  There are additional known
issues with these patches (drive-by-findings in related code).

There are many old bugs all over netfilter and our ability to review
feature patches has come to a complete halt due to lack of time.
There are further security bugs that we cannot address
due to lack of time, maintainers and reviewers.

Other remarks: The xtables 32bit compat interface is already
off in many vendor kernels, the plan is to remove it soon.

1) Prevent RST packets with invalid sequence numbers from forcing TCP
   connections into the CLOSE state without a direction check.
   From Hamza Mahfooz.
2) Re-derive the TCP header pointer after skb_ensure_writable in
   synproxy_tstamp_adjust. Prevent use-after-free and invalid checksum
   updates caused by stale pointers during buffer expansion.
   From Chris Mason.
3) Fix a race condition causing keymap list corruption in conntracks gre/pptp
   helper.
4) Use raw_smp_processor_id() in xt_cpu to prevent splats under
   PREEMPT_RCU.
5) Disable netfilter payload mangling in user namespaces (nft_payload.c
   and nf_queue).
   TCP option mangling via nft_exthdr.c remains enabled.
   There will be followups here to restrict resp. revalidate
   headers.
6) Fix an out-of-bounds read in ebtables's compat_mtw_from_user function.
7) Use list_for_each_entry_rcu() to traverse fib6_siblings in
   nft_fib6_info_nh_uses_dev(). Ensure safe list walking under RCU.
8) Fix an out-of-bounds read in nft_fib_ipv6 caused by incorrect list
   traversal.
9) Add nft_fib_nexthop selftest to netfilter. Cover nexthop enumeration for
    single, group, and multipath route shapes.
    All three nft_fib6 fixes from Jiayuan Chen.
10) Fix destination corruption in shift operations when source and destination
    registers overlap.  Reject partial register overlap for all operations
    from control plane.  From Fernando Fernandez Mancera.

f9f57971da dm-inlinecrypt: add support for hardware-wrapped keys
Add support for hardware-wrapped encryption keys to the
dm-inlinecrypt target.

Introduce a new optional argument <key_type> to indicate
whether the provided key is a raw key or a hardware-wrapped
key. Based on this flag, the appropriate blk-crypto key type
is selected when initializing the key.

This allows dm-inlinecrypt to work with hardware that requires
keys to be wrapped and managed by the underlying inline
encryption engine.

Update the target argument parsing accordingly and pass the
key type to blk_crypto_init_key(). Documentation is also
updated to reflect the new parameter and usage.

4fbc823000 RDMA/counter: Fix num_counters leak on bind_qp failure in alloc_and_bind()
When __rdma_counter_bind_qp() fails in alloc_and_bind(), the error path
jumps to err_mode which frees the counter without decrementing
port_counter->num_counters. The only place that decrements is
rdma_counter_free(), which is unreachable since the counter was never
successfully bound.

This leak accumulates across repeated failures, permanently preventing
the port from switching to AUTO mode (-EBUSY in __counter_set_mode())
and blocking the MANUAL→NONE auto-revert in rdma_counter_free(). When
the mode was NONE before the call, the MANUAL mode set by
__counter_set_mode() also leaks since the revert logic is never
reached.

Add an err_bind label between the num_counters increment and the
existing err_mode label. It decrements num_counters and mirrors the
MANUAL→NONE revert from rdma_counter_free(), ensuring the port state
is fully restored on bind failure.

49abb5d6e1 remoteproc: use rsc_table_for_each_entry() in rproc_handle_resources()
Replace the open-coded resource table iteration loop in
rproc_handle_resources() with the rsc_table_for_each_entry() helper.

The remoteproc-specific dispatch logic (vendor resource handling via
rproc_handle_rsc(), RSC_LAST bounds check, handler table lookup) is
moved into a local callback rproc_handle_rsc_entry(), keeping the
iteration mechanics in one canonical place.

The callback receives the payload offset within the table so that
handlers which write back into the resource table (e.g.
rproc_handle_carveout() recording a dynamically allocated address via

0590420c2f remoteproc: Move resource table data structure to its own header
The resource table data structure has traditionally been associated with
the remoteproc framework, where the resource table is included as a
section within the remote processor firmware binary. However, it is also
possible to obtain the resource table through other means—such as from a
reserved memory region populated by the boot firmware, statically
maintained driver data, or via a secure SMC call—when it is not embedded
in the firmware.

There are multiple Qualcomm remote processors (e.g., Venus, Iris, GPU,
etc.) in the upstream kernel that do not use the remoteproc framework to
manage their lifecycle for various reasons.

When Linux is running at EL2, similar to the Qualcomm PAS driver
(qcom_q6v5_pas.c), client drivers for subsystems like video and GPU may
also want to use the resource table SMC call to retrieve and map
resources before they are used by the remote processor.

In such cases, the resource table data structure is no longer tightly
coupled with the remoteproc headers. Client drivers that do not use the
remoteproc framework should still be able to parse the resource table
obtained through alternative means. Therefore, there is a need to
decouple the resource table definitions from the remoteproc headers.

86f1d0f063 net/mlx5: HWS: Reject unsupported remove-header action
mlx5_cmd_hws_packet_reformat_alloc() handles
MLX5_REFORMAT_TYPE_REMOVE_HDR by looking up a matching HWS remove-header
action.

If mlx5_fs_get_action_remove_header_vlan() returns NULL, the code only
logs an error and continues. The function then returns success with a NULL
HWS action stored in the packet-reformat object.

Return an error when no matching remove-header action is available.

Fixes: aecd9d1020 ("net/mlx5: fs, add HWS packet reformat API function")
