tbnet_poll() assembles a multi-frame ThunderboltIP packet into one skb. The
first frame goes into the skb linear area and every further frame is added as
a page fragment.
skb_add_rx_frag(skb, skb_shinfo(skb)->nr_frags,
page, hdr_size, frame_size,
TBNET_RX_PAGE_SIZE - hdr_size);
A packet of frame_count frames therefore ends up with frame_count - 1
fragments. tbnet_check_frame() only bounds the peer supplied frame_count to
TBNET_RING_SIZE / 4 (64), which is far above MAX_SKB_FRAGS (17 by default). A
peer that sends a packet of 19 or more small frames pushes nr_frags past
MAX_SKB_FRAGS, so skb_add_rx_frag() writes past skb_shinfo()->frags[] and
corrupts memory after the shared info.
Tighten the start of packet bound to MAX_SKB_FRAGS + 1 so a packet can never
produce more fragments than frags[] can hold. This matches the recent skb
frags overflow fixes in other receive paths, for example f0813bcd2d ("net:
wwan: t7xx: fix potential skb->frags overflow in RX path") and 600dc40554
("net: usb: cdc-phonet: fix skb frags[] overflow in rx_complete()").

nt->buf is exactly MAX_PRINT_CHUNK bytes, but scnprintf() reserves one
byte for its NUL terminator, so a non-fragmented payload of exactly
MAX_PRINT_CHUNK loses its last byte (emitted as a stray NUL in the
release path). Grow nt->buf to MAX_PRINT_CHUNK + 1 and bound the
scnprintf() calls with sizeof(nt->buf); the transmitted length stays
capped at MAX_PRINT_CHUNK.
Alternatively, nt->buf could be left at MAX_PRINT_CHUNK and the NUL byte
reserved by routing exactly-MAX_PRINT_CHUNK payloads to fragmentation
('len < MAX_PRINT_CHUNK'), at the cost of fragmenting those messages.
But it would look less sane, thus the current approach.

__skb_flow_dissect() unconditionally reads 12 bytes from eth_hdr(skb)
when FLOW_DISSECTOR_KEY_ETH_ADDRS is requested. This assumes the skb
has a valid Ethernet header at mac_header, which is not always the case.
The problem can be triggered by:
1. Creating a TUN device in L3 mode (IFF_TUN, hard_header_len=0)
2. Attaching a multiq qdisc with a flower filter matching on eth_src
3. Sending a packet through AF_PACKET
Since TUN in L3 mode has no link-layer header, mac_header points to
the L3 data area. The flow dissector reads 12 bytes of uninitialized
skb memory, which then propagates through fl_set_masked_key() and is
used as a rhashtable lookup key in __fl_lookup(), as reported by KMSAN.
Rejecting the filter in the control path (at tc filter add time) is
not feasible because TC filter blocks can be shared between arbitrary
devices -- a filter installed on an Ethernet device may later classify
packets on a headerless device through a shared block. The device
association is not fixed at filter creation time.
Fix this by gating the memcpy on dev->type == ARPHRD_ETHER, which
ensures only true Ethernet-framed packets have their addresses read.
This is more precise than the previous hard_header_len >= 12 check,
which would incorrectly pass for non-Ethernet link types like IPoIB
(ARPHRD_INFINIBAND, hard_header_len=24) and FDDI (hard_header_len=21)
whose L2 headers are not in Ethernet format. Additionally check
skb_mac_header_was_set() to guard against the pathological case where
mac_header is the unset sentinel (~0U), which would cause eth_hdr() to
return a wild pointer.
For the act_mirred redirect case (Ethernet packet redirected to a
non-Ethernet device sharing a TC block), zeroing the key is the correct
behavior: the packet is now being classified on the target device, where
Ethernet address matching is not semantically meaningful.
Note: on non-Ethernet devices, the zeroed key will match a filter
configured with all-zero MAC addresses. This is an improvement over the
previous behavior where uninitialized memory could randomly match any
filter.

The MACB found in the Raspberry Pi RP1 suffers from sporadic stalls on
the TX queue.
While the exact root cause is not yet fully understood, it is likely
related to a hardware issue where a TSTART write to the NCR register
is missed, preventing the transmission from being kicked off.
Implement a timeout callback to handle TX queue stalls, triggering the
existing restart mechanism to recover.

When a node is created via rate-new with tc-bw and a parent node,
devlink_nl_rate_set() executes the sequence of ops. It bails out on the
first failure and doesn't rollback anything. For most things that is
fine (setting some numbers), but the parent set can leak if there's
another failure after that.
That is precisely what happens when parent setting isn't the last block
in the function. After the referenced "Fixes" commit, when tc-bw fails
to be set the function bails out after having set the parent and
incremented its refcount.
There are two callers:
- devlink_nl_rate_set_doit() is fine, it just reports the error.
- but devlink_nl_rate_new_doit() frees the newly created node and leaks
the parent refcnt.
Fix that by reordering the blocks so parent setting is last and adding a
comment explaining this so future modification preserve the ordering
(hopefully).

receive_big() bounds the device-announced length by
(big_packets_num_skbfrags + 1) * PAGE_SIZE. That is still too loose:
add_recvbuf_big() sets sg[1] to start at offset
sizeof(struct padded_vnet_hdr) into the first page, so the chain
actually carries hdr_len + (PAGE_SIZE - sizeof(padded_vnet_hdr)) +
big_packets_num_skbfrags * PAGE_SIZE bytes -- 20 bytes less than the
check allows for the common hdr_len == 12 case.
A malicious virtio backend can announce a len in that gap. page_to_skb()
then walks one frag past the page chain, storing a NULL page->private
into skb_shinfo()->frags[MAX_SKB_FRAGS], which is both an out-of-bounds
write past the static frag array and a NULL frag handed up the rx path.
Bound len by the size add_recvbuf_big() actually advertised.

intended usage and frequently counter-intuitive semantics: it may not
NUL-terminate the destination, and it unconditionally zero-pads to the
full length, which isn't always needed. All former callers have been
migrated[1] to:
- strscpy() for NUL-terminated destinations
- strscpy_pad() for NUL-terminated destinations needing zero-padding
- strtomem_pad() for non-NUL-terminated fixed-width fields
- memcpy_and_pad() for bounded copies with explicit padding
- memcpy() for known-length copies

SMB2_flush() keeps its response buffer bookkeeping across replay
attempts. If a replayable flush response is received and the retry then
fails before cifs_send_recv() stores a replacement response, flush_exit
will free the stale response pointer a second time.
Reinitialize resp_buftype and rsp_iov at the top of the replay loop so
cleanup only acts on response state produced by the current attempt.
This fixes a double-free without changing replay handling for successful
requests.

Remove the reference to the obsolete kselftest wiki.
The kselftest wiki is marked obsolete and is no longer updated. The last
edit was in 2019, and the information is outdated, referring readers for
support to IRC networks that have not been used for years, and to kernel
versions that are no longer supported.
If there is any relevant information left in the wiki it needs to be
cleaned up and moved into the canonical kselftest documentation here.

When reading .config input, Kconfig stores user-provided values first
and then resolves the final value after applying dependencies, ranges,
and other constraints.
If the final value differs from the user input, Kconfig already tracks
that state internally, but it does not provide a focused diagnostic to
show which explicit inputs were adjusted. This is particularly confusing
for requested values that get forced down by unmet dependencies or
clamped by ranges.
Add an opt-in diagnostic controlled by KCONFIG_WARN_CHANGED_INPUT. Emit
the warnings from conf_write() and conf_write_defconfig() after value
resolution. Print the diagnostic to stderr directly, not through the
normal message callback, so it remains visible when conf is run with -s,
such as from make -s.
Keep the diagnostic out of the conf_message() formatting buffer so long
warning lists are not truncated, and mark processed symbols as written
before the SYMBOL_WRITE check so duplicate menu nodes cannot emit
duplicate warnings.
Document the new environment variable and add tests for olddefconfig,
savedefconfig, and the silent-conf path.

When building the kernel with Clang ThinLTO enabled, the compiler
can mangle static variable names by appending suffixes such as
".llvm.<hash>" to prevent naming collisions across translation units.
This name mangling breaks the section mismatch whitelisting in modpost.
modpost relies on glob patterns (e.g., "*_ops" or "*_probe") to identify
safe references between permanent data and initialization code. Because
the LTO suffix modifies the end of the symbol name, legitimately
whitelisted structures fail the match, resulting in false positive
warnings.
For example, a static pernet_operations struct triggers the following:
WARNING: modpost: vmlinux: section mismatch in reference: \
ping_v4_net_ops.llvm.5641696707737373282 (section: .data) -> \
ping_v4_proc_init_net (section: .init.text)
Fix this by ignoring "*_ops.llvm.*" in "from" symbol names (the same
as "*_ops").

rpcif_spi_resume() currently passes the SPI controller device to
rpcif_hw_init(), but the function should be called with the RPC
interface device.
Retrieve the rpcif private data from the SPI controller and pass
rpc->dev instead. Also propagate the return value of rpcif_hw_init() so
that a failure during resume is properly reported rather than silently
ignored.

pci_host_common_init() is used by several generic ECAM host drivers.
After PCI core changes around pci_flags and preserve_config, these hosts
no longer opted into full bus number reassignment the way they did
before, which broke enumeration of devices on a Marvell CN106XX board.
When PCI_PROBE_ONLY is not set, add PCI_REASSIGN_ALL_BUS so
pci_scan_bridge_extend() takes the reassignment path: bus numbers can be
assigned from firmware EA data (e.g. pci_ea_fixed_busnrs()). Skip the
flag in probe-only mode so existing assignments are not overridden.
Fixes: 7246a4520b ("PCI: Use preserve_config in place of pci_flags")
