smb client fixes for v7.3-rc4
A batch of bug fixes for the smb client:
- Fix multiple out-of-bounds reads and use-after-frees in the SMB2/3
receive path that are reachable from a malicious or compromised
server: a stale next_buffer pointer and an integer overflow in
compound encrypted frame handling, missing minimum-PDU-size and
per-sub-PDU length validation before parsing command-specific
response fields, missing bounds checks in DFS referral, server
interface list, EA list, POSIX SID, snapshot enumeration and SMB1
reparse point parsing
- Fix use-after-frees and races in multichannel and connection
teardown, including an interface freed while still in use when
adding channels, a server used after its channel reference was
dropped, a reconnect work item left queued after the server is
freed and an uninitialized reconnect list node
- Fix a heap overflow in the native symlink parser: an absolute
target without an NT drive prefix caused out-of-bounds writes and a
u16 length underflow leading to a 64K memcpy into a small buffer,
triggerable by a user with write access to a mounted share under
default settings
- Fix WSL reparse point parsing: use unaligned accessors for the
packed extended-attribute payload to avoid alignment faults on some
architectures and stop leaving partially mutated fattr fields on
parse failure
- Fix lease break ACKs being sent through the wrong session on
multiuser mounts, which caused read failures (e.g. on NetApp
ONTAP/Azure Files) when copying files
- Fix an smbd_connection leak when cifs_get_tcp_session() fails after
an RDMA connection was already established

SCSI fixes on 20260918
Four driver fixes, three of which are minor and one of which (fnic) tries to add some logic to try to avoid MSI-X being ineffective if hyperthreading is disabled. The core fix adds validation to mode sense buffer sizes because it is used by ATA and could, theoretically, be exploited by a specially crafted USB device that can simply be plugged in to any laptop or server.

- Fix session expiration so that valid sessions are no longer removed
after ten seconds of inactivity when a new session setup request is
received. Sessions now expire only after credential expiration, while
stale unauthenticated sessions are cleaned up after a 45-second timeout.
- Keep earlier responses in compound requests when Query Info fails
because the output buffer is too small. The error response is appended
without truncating preceding responses.
- Return STATUS_BUFFER_OVERFLOW for partial
FILE_NORMALIZED_NAME_INFORMATION responses instead of incorrectly
returning STATUS_INFO_LENGTH_MISMATCH.

- Make MFT extension work on existing Windows-created volumes by
dynamically reserving MFT tail records, accounting for records added
during allocation, and avoiding false -ENOSPC failures.
- Repack non-resident $MFT/$ATTRIBUTE_LIST when its mapping pairs no longer
fit in the base MFT record, while propagating allocation and writeback
errors.
- Serialize runlist updates with the runlist lock and restore both the
in-memory runlist and on-disk mapping pairs when allocation rollback is
required.
- Propagate folio errors and harden inode failure handling by treating
interrupted reads as transient failures and discarding and unhashing
inodes whose initialization fails.
- Fix the $MFTMirr write offset when mirror records span multiple folios,
preventing mirror records from overwriting the first record with large
MFT record sizes.

watchdog: da9063: fix suspend/resume handling of HW_RUNNING watchdog
da9063_wdt_suspend() and da9063_wdt_resume() only check watchdog_active(),
when the watchdog is left running by the driver sets
WDOG_HW_RUNNING in da9063_wdt_probe() but userspace never opens the
device, so WDOG_ACTIVE remains cleared, the wdt_disable() will not be
executed in da9063_wdt_suspend. In this case, the suspend callback is
a no-op and the watchdog keeps counting during system suspend,
leading to an unexpected system reset.
Check WDOG_HW_RUNNING and wdd，can fix this issue.

soc: samsung: exynos-pmu: fix use-after-free of interrupt generator node
The setup_cpuhp_and_cpuidle() parses the device tree node for the
interrupt generation block via of_parse_phandle() and decrements its
reference count using of_node_put() immediately after fetching the resource
address. However, later the intr_gen_node pointer is passed into
of_syscon_register_regmap().
Fix this by declaring intr_gen_node with __free() and removing
of_node_put().

cifs: Fix server use-after-free in cifs_chan_skip_or_disable()
When a secondary channel is no longer supported by the server,
cifs_chan_skip_or_disable() drops the channel reference with
cifs_put_tcp_session() and then continues to use the server pointer by
calling cifs_signal_cifsd_for_reconnect() on it and reading its
primary_server pointer. cifs_put_tcp_session() can drop the last
reference of the channel and tear it down, so both the channel and the
primary server (whose reference is also dropped by
cifs_put_tcp_session()) can be freed before they are signaled for
reconnect.
Signal the channel and the primary server and capture the primary
server pointer before dropping the channel reference with
cifs_put_tcp_session().

smb: client: fix reparse buffer bounds in cifs_query_reparse_point()
In cifs_query_reparse_point(), the start >= end check before casting to
struct reparse_data_buffer * only ensures the start pointer is within the
response. It fails to verify that there is enough space remaining for the
fixed 8-byte header of the structure.
If a server provides a DataOffset that leaves less than 8 bytes remaining,
the check passes, but subsequent reads of ReparseTag and ReparseDataLength
will occur out-of-bounds.
Fix this by ensuring the remaining space is at least the size of the
reparse_data_buffer structure before accessing its fields.

smb: client: fix potential OOB read in smb3_enum_snapshots()
If snapshot_array_size is smaller than GMT_TOKEN_SIZE,
smb3_enum_snapshots() sets ret_data_len to
sizeof(struct smb_snapshot_array) without verifying the actual length
of the server's reply.
Because SMB2_ioctl() places no lower bound on the server-supplied
OutputCount and allocates retbuf to exactly that length, a short reply
results in ret_data_len exceeding the size of retbuf. The subsequent
copy_to_user() then reads past the end of retbuf, leaking adjacent slab
memory to userspace. The subsequent clamp check is ineffective as it
only reduces ret_data_len.
Fix this by rejecting replies shorter than
sizeof(struct smb_snapshot_array) with -EIO. Note that the bound is set
to the 12-byte struct size rather than the 16-byte
MIN_SNAPSHOT_ARRAY_SIZE defined in MS-SMB2 3.3.5.15.1, because 12 bytes
is exactly what copy_to_user() attempts to read.

smb: client: fix missing iov bounds check in parse_posix_sids()
In parse_posix_sids(), sidsbuf_end is calculated using the server-supplied
out_len without being validated against the actual length of the received
iov (iov_len).
If a server provides an inflated out_len, sidsbuf_end will point past the
end of the iov. This defeats the bounds guards in posix_info_sid_size(),
allowing out-of-bounds reads into adjacent kernel memory.
Fix this by rejecting responses where the calculated sidsbuf_end would
exceed the received iov boundaries or cause pointer wraparound.

smb: client: fix OOB struct field reads in move_smb2_ea_to_cifs()
In move_smb2_ea_to_cifs(), the while (src_size > 0) loop condition is
insufficient. It allows iteration to continue even if the remaining
src_size is too small to contain a complete smb2_ea_info structure.
Consequently, reads of ea_name_length and ea_value_length can occur
out-of-bounds.
Fix this by ensuring src_size >= sizeof(*src) before attempting to read
any structure fields. Additionally, reject any next_entry_offset that is
smaller than sizeof(*src) or that would advance the pointer beyond the
available buffer.
Note that for calls where the server returns a malformed EA list, the
error returned to userspace changes from -ENODATA (getxattr) or
-ERANGE (listxattr) to -EIO. This correctly signals a server protocol
error rather than misleadingly indicating "attribute not present" or
"output buffer too small".

smb: client: reject short Next offsets in parse_server_interfaces()
In parse_server_interfaces(), the server-supplied Next offset is
validated against bytes_left, but not against the size of the interface
structure itself.
A small, non-zero Next value can pass the bounds check but advance the
pointer by less than sizeof(*p). This causes the next iteration of the
loop to read misaligned, overlapping structure fields.
Fix this by ensuring the Next offset is at least sizeof(*p).

smb: client: fix missing lower-bound check on DFS referral string offsets
parse_dfs_referrals() checks that DfsPathOffset and NetworkAddressOffset
do not exceed the buffer end, but fails to check that they don't point
inside the referral header itself.
If a server provides an offset smaller than
sizeof(struct dfs_referral_level_3), the derived string pointer overlaps
with the struct fields, causing cifs_strndup_from_utf16() to interpret

smb: client: fix server->total_read for compound encrypted PDUs
In receive_encrypted_standard(), server->total_read is left at the
full decrypted frame size when walking sub-PDUs of a compound encrypted
frame. As a result, cifs_handle_standard() passes this full size
to smb2_check_message(), causing the PDU length guards to incorrectly
validate the entire compound frame instead of the current sub-PDU.
This allows truncated non-last sub-PDUs to bypass length validation,
leading to out-of-bounds reads in smb2_get_data_area_len().
Fix this by setting server->total_read to the true length of the
current sub-PDU: next_cmd for non-last sub-PDUs, and the remaining
pdu_length for the last one.

smb: client: validate minimum PDU size before smb2_get_data_area_len()
__smb2_calc_size() calls smb2_get_data_area_len(), which reads command-specific struct fields to locate the data area. However, smb2_check_message() only validates StructureSize2, meaning a truncated response could cause smb2_get_data_area_len() to read out-of-bounds. Replace has_smb2_data_area[] with smb2_min_pdu_len[], which is now used to indicate both whether a command's response has a data area and the size of that fixed response struct. A non-zero entry means the command has a data area, and is the minimum length required before the struct is read. For each command with a data area, PDUs shorter than this minimum size are rejected instead of parsed. The minimum is not applied to SMB2 error responses, which carry only the 9-byte error body, the same exemption the StructureSize2 check above it already makes. STATUS_MORE_PROCESSING_REQUIRED is treated as a normal reply, since an in-progress SESSION_SETUP response carries a full body and a security blob.

smb: client: fix next_buffer UAF and NextCommand bounds in compound PDUs
Fix several related bounds checking and pointer lifecycle issues in
receive_encrypted_standard()'s handling of compound encrypted frames:
- Clear next_buffer after assigning it to server->bigbuf. A stale
next_buffer pointer can lead to a use-after-free on subsequent
error paths.
- Update pdu_length to the decrypted plaintext size (buf_size). Using
the pre-decryption length allows NextCommand to point into stale
ciphertext residue.
- Reject next_cmd values smaller than MID_HEADER_SIZE(server).
- Fix an integer overflow in the upper bound check by verifying
pdu_length - next_cmd < MID_HEADER_SIZE(server), ensuring the
trailing slice is large enough for a header.

mptcp: avoid unneeded actions on subflow reset
Once in a blue moon, the mptcp receive path can recursively call
mptcp_data_ready() via state change under unlucky error conditions, and
then try to hold the data lock again.
Break the recursion loop explicitly checking for the exceptional
condition.
Add a new flag instead of using an existing one like 'closing', to exit
early in subflow_state_change(), and explicitly flush the RX queue at
reset time.
This avoids unneeded processing to check for available data -- calling
get_mapping_status() and more on a dying subflow -- but also in error
reporting and worker scheduling.
Note that we must consume the currently peeked skb before invoking
mptcp_dss_corruption to avoid consuming it again after the eventual
reset has freed it.

net: skbuff: do not leave stale header offsets after pskb_carve()
pskb_carve_inside_header() and pskb_carve_inside_nonlinear() remove
the first bytes of a packet and reallocate skb->head.
All the headers that were present before the operation are gone,
but both functions call skb_headers_offset_update(skb, 0), which
is a no-op : skb->mac_header, skb->network_header,
skb->transport_header and skb->csum_start keep their old values and
now describe bytes which are no longer there.
Both helpers size the new head from the old skb_end_offset(), so the
stale offsets still land inside the new allocation. They point past
skb_tail_pointer() though, to bytes that were never initialized.
pskb_carve_inside_nonlinear() is the worst case, because it leaves a
zombie skb with an empty linear part (skb->data ==
skb_tail_pointer(skb), skb_headlen(skb) == 0), while
skb_mac_header_was_set() is still true and skb->mac_header is way
ahead of skb->data.
The only user of pskb_extract() is rds_tcp_data_recv(), and the
carved skb is queued on tinc->ti_skb_list. When the RDS incoming
message is released, rds_tcp_inc_free() calls skb_queue_purge(),
which frees the skbs with SKB_DROP_REASON_QUEUE_PURGE. This is
visible from drop_monitor, which then tries to pull back to the
(bogus) mac header :
skbuff: __skb_pull(len=234)
skb len=6968 data_len=6968 headroom=0 headlen=0 tailroom=0
end-tail=384 mac=(234,14) mac_len=14 net=(248,40) trans=288
shinfo(txflags=0 nr_frags=1 gso(size=1428 type=16 segs=5))
csum(0x100120 start=288 offset=16 ip_summed=3 complete_sw=0 valid=1 level=0)
hash(0x7b446c6c sw=0 l4=1) proto=0x86dd pkttype=0 iif=60
kernel BUG at ./include/linux/skbuff.h:2847!
Add skb_carve_reset_headers() to mark the mac and transport headers
as not set, reset the network header, clear skb->mac_len, and drop
a now meaningless CHECKSUM_PARTIAL (csum_start no longer describes
anything).
Invalidate the inner offsets as well. Unlike mac_header and
transport_header they have no "unset" sentinel, so a leftover
non-zero value still looks like a real header. Zero
skb->inner_mac_header, skb->inner_network_header,
skb->inner_transport_header, skb->inner_protocol and
skb->encapsulation, so that all the header state is invalidated in
one place.
v2: fixed an inaccurate changelog. The stale offsets stay inside the
new skb->head, which is never smaller than the old one, they
simply point past skb_tail_pointer() to bytes that are gone.
Thanks to Xuanqiang Luo for insisting on this.
Also invalidate the inner header state, as suggested by the
netdev AI review :

selftests: net: packetdrill: test exclusion of old ACK from TCP fast path
Add a packetdrill test for an in-sequence data segment carrying an
excessively old ACK.
Verify that the segment falls through from the TCP fast path to the slow
path, where the existing ACK validation rejects it and sends a challenge
ACK. The payload is not accepted and RCV.NXT remains unchanged.

dpll: reject a reference sync pin which is not on the pin's dpll
dpll_pin_ref_sync_state_set() resolves the partner's driver private data with dpll_pin_on_dpll_priv() and passes the result to ref_sync_get() and ref_sync_set() without looking at it. The helper returns NULL when the partner holds no ref on that dpll. Of the two drivers implementing the feature only zl3073x dereferences the pointer (sync_pin->id); ice ignores it, so ice cannot fault here. The NULL is a teardown race, not a steady state - zl3073x registers every input pin with every channel, so the partner is normally present on the dpll the base pin resolves to. zl3073x_dev_stop() unregisters pins one at a time, taking and dropping dpll_lock for each, and between the partner's turn and the base pin's the partner is out of that dpll's pin_refs while still registered with the channels not yet torn down, so dpll_pin_available() keeps passing. That path is not only driver removal: devlink reload and devlink dev flash both run zl3073x_dev_stop(). Reproduced by holding that state open with a mock dpll device, which is where the frame name comes from: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: Oops: 0000 [#1] SMP NOPTI RIP: 0010:mock_ref_sync_get+0x5/0x30 Call Trace: <TASK> dpll_pin_ref_sync_set+0x19f/0x4a0 dpll_nl_pin_set_doit+0x17d/0x840 genl_family_rcv_msg_doit+0xd6/0x130 genl_rcv_msg+0x181/0x2b0 netlink_rcv_skb+0x55/0x100 genl_rcv+0x23/0x30 netlink_unicast+0x24d/0x370 netlink_sendmsg+0x1e2/0x420 __sys_sendto+0x1db/0x1f0 __x64_sys_sendto+0x1f/0x30 do_syscall_64+0xe1/0x490 Commit |

net: mvpp2: prevent buffer overflow in page_pool allocation
The per‑processor buffering scheme is supported only if the
number of pools (nrxqs * 2) does not exceed MVPP2_BM_MAX_POOLS (8).
This is already checked in mvpp2_probe() during the initial
activation of percpu_pools.
However, mvpp2_change_mtu() may later call
mvpp2_bm_switch_buffers(priv, true) without this check, which can
lead to an out-of-bounds access in the priv->page_pool array in
mvpp2_bm_init(). The array is sized to hold MVPP2_PORT_MAX_RXQ
entries, and mvpp2_get_nrxqs() may return exactly that value. The
per-CPU scheme then doubles it to nrxqs * 2, exceeding the array
bounds.
Check that the hardware version is MVPP22 or newer and that the
number of pools (nrxqs * 2) does not exceed MVPP2_BM_MAX_POOLS
before switching to per-CPU mode.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

net: macb: fix ordering around PTP timestamp read
PTP_SYS_OFFSET_EXTENDED returns system timestamps that do not correctly
bracket the PHC register read on MACB/GEM. On a Raspberry Pi 5, the
returned interval can be as short as 37 ns, while an ordered register
read takes approximately 1 us. This biases the midpoint used by phc2sys,
causing CLOCK_REALTIME to run approximately 0.5 us ahead when synchronized
to the PHC.
gem_tsu_get_time() reads the nanoseconds register using the driver's
relaxed MMIO accessor. On weakly ordered systems, the subsequent system
timestamp can be taken before the register read completes. The internal
smp_rmb() in the pre-timestamp path also does not guarantee ordering
against the subsequent MMIO read.
Add rmb() before and after the bracketed nanoseconds read in both the
normal and seconds rollover paths so the system timestamps bracket the
PHC read. Adding the post-read barrier increases the minimum interval on
the same Raspberry Pi 5 to approximately 1 us.

Merge branch 'net-psp-avoid-conflicts-with-skb-decrypted-and-sk_validate_xmit_skb'
Daniel Zahka says:
====================
net: psp: avoid conflicts with skb->decrypted and sk_validate_xmit_skb()
Sashiko's review of commit da630d1da2b1 ("netdevsim: psp: drop tx key
ops") [1] showed that there is a hazard between PSP and offloaded TLS,
where both can clobber what the other set in the sk_validate_xmit_skb
callback.
It was discussed further on the mailing list [2], and it was pointed out
that there are conflicts with PSP and TLS ULP both using the
skb->decrypted bit.
The simplest fix is to make psp and tls mutually exclusive. This series
goes a bit further and makes psp exclusive with all TCP ULPs. The PSP
implementation that we have is not designed to be used with any TCP ULP,
so don't allow a socket to have state for both.
I will send a subsequent series to net-next which will remove the
ability to perform the rx-assoc and tx-assoc psp netlink calls on
sockets that are not in the TCP_ESTABLISHED state. This will close the
remaining quirk that a sk_clone() on a listen socket with psp tx-assoc
state will leave a stale sk->sk_validate_xmit_skb call back on a new,
non-psp socket. I do not believe that change needs to be regarded as a
fix, because it only stands to add unecessary validation code in the tx
path.

net: psp: avoid conflicts with skb->decrypted and sk_validate_xmit_skb()
PSP conflicts with TLS ULP in its usage of both skb->decrypted and
sk->sk_validate_xmit_skb().
Make PSP mutually exclusive with TLS ULP, the only other user of either
of these. As other users of skb->decrypted come along, they can be added
to sk_has_decrypt_user(). It would make sense to also assert that
sk->sk_validate_xmit_skb() is also NULL in both of these setup paths for
similar future proofing, but the PSP listener/sk_clone() path is still
broken and it could be seen as a regression to not allow rx assoc to run
on a child of a listener socket with PSP tx assoc state.
Include all TCP ULPs in the sk_has_decrypt_user() check, even though TLS
is the only one that conflicts with PSP via the decrypted bit. This is
intentional because PSP was not designed to be used with ULPs. It is
best to close off surface area that may make bugs reachable, until
someone wishes to design and test an actual user of PSP with ULPs.

net: stmmac: preserve real_num_tx_queues on mqprio setup failure
With the FPE preemption-class mapping error now propagated from
stmmac_fpe_map_preemption_class(), tc_setup_dwmac510_mqprio() can fail
on the mapping step. The error path used to call stmmac_reset_tc_mqprio(),
which resets the number of real TX queues to priv->plat->tx_queues_to_use
(the platform maximum), overwriting the value that was active before the
offload was attempted (for example a lower count left over from a previous
mqprio configuration).
The issue can be triggered using the following configuration:
# First mqprio config lowers the hw queue count below the platform
# default (e.g. 8 TX queues).
$tc qdisc add dev eth0 root handle 1: mqprio queues 2@0 2@2
# Replace mqprio configuration with a second one that fails FPE
# preemption-class mapping. stmmac driver resets the real_num_tx_queues
# to the platform maximum, losing the previous configuration.
$tc qdisc replace dev eth0 root handle 2: mqprio queues 2@0 2@2 fp E P
Save ndev->real_num_tx_queues before lowering it and restore it,
together with the TC-to-queue and priority-to-TC mappings, when the FPE
preemption-class mapping fails, instead of resetting the queue count to
the platform maximum.
Note that a failed setup makes the qdisc layer run mqprio_destroy() on
the new qdisc. Because priv->hw_offload is only assigned after
ndo_setup_tc() succeeds, mqprio_destroy() calls netdev_set_num_tc(dev, 0),
so dev->num_tc ends up 0 regardless of the driver-side restore and the
previous qdisc is not reactivated. The restore is still needed to keep
real_num_tx_queues and to avoid leaving the failed configuration's
TC-to-queue and priority-to-TC mappings in place.
