ASAN generates special synthetic symbols to help check for ODR
violations. These synthetic symbols lack debug information, so
gendwarfksyms emits warnings when processing them. No code should ever
have a dependency on these symbols, so we should not be exporting them,
just like the __cfi symbols.

MS-SMB2 section 2.2.13.2.10 specifies that 'epoch' should be a 16-bit
unsigned integer used to track lease state changes. Change the data
type of all instances of 'epoch' from unsigned int to __u16. This
simplifies the epoch change comparisons and makes the code more
compliant with the protocol spec.

Commit 1db806ec06b7 ("PCI/ASPM: Save parent L1SS config in
pci_save_aspm_l1ss_state()") aimed to perform L1SS config save for both the
Upstream Port and its upstream bridge when handling an Upstream Port, which
matches what the L1SS restore side does. However, parent->state_saved can
be set true at an earlier time when the upstream bridge saved other parts
of its state. Then later when attempting to save the L1SS config while
handling the Upstream Port, parent->state_saved is true in
pci_save_aspm_l1ss_state() resulting in early return and skipping saving
bridge's L1SS config because it is assumed to be already saved. Later on
restore, junk is written into L1SS config which causes issues with some
devices.
Remove parent->state_saved check and unconditionally save L1SS config also
for the upstream bridge from an Upstream Port which ought to be harmless
from correctness point of view. With the Upstream Port check now present,
saving the L1SS config more than once for the bridge is no longer a problem
(unlike when the parent->state_saved check got introduced into the fix
during its development).

In [2] it was pointed out that parts of setarch weren't working
properly on alpha because it has it's own SET_PERSONALITY
implementation. In the discussion that followed Richard Henderson
pointed out that the 32bit pointer support for alpha was never
completed.
Fix this by removing alpha's 32bit pointer support.
As a bit of paranoia refuse to execute any alpha binaries that have
the EF_ALPHA_32BIT flag set. Just in case someone somewhere has
binaries that try to use alpha's 32bit pointer support.

The find_preferred_mode() functions takes the mode_config mutex, but due
to the order most tests have, is called with the crtc_ww_class_mutex
taken. This raises a warning for a circular dependency when running the

has been created to avoid the issue.

On an aarch64 kernel with CONFIG_PAGE_SIZE_64KB=y,
arena_htab tests cause a segmentation fault and soft lockup.
The same failure is not observed with 4k pages on aarch64.
It turns out arena_map_free() is calling
apply_to_existing_page_range() with the address returned by
bpf_arena_get_kern_vm_start(). If this address is not page-aligned
the code ends up calling apply_to_pte_range() with that unaligned
address causing soft lockup.
Fix it by round up GUARD_SZ to PAGE_SIZE << 1 so that the
division by 2 in bpf_arena_get_kern_vm_start() returns
a page-aligned value.

Other, non DAI copier widgets could have the same stream name (sname) as
the ALH copier and in that case the copier->data is NULL, no alh_data is
attached, which could lead to NULL pointer dereference.
We could check for this NULL pointer in sof_ipc4_prepare_copier_module()
and avoid the crash, but a similar loop in sof_ipc4_widget_setup_comp_dai()
will miscalculate the ALH device count, causing broken audio.
The correct fix is to harden the matching logic by making sure that the
1. widget is a DAI widget - so dai = w->private is valid
2. the dai (and thus the copier) is ALH copier

For systems which load firmware on the cs35l41 which use ACPI, the
_SUB value is used to differentiate firmware and tuning files for the
individual systems. In the case where a system does not have a _SUB
defined in ACPI node for cs35l41, there needs to be a fallback to
allow the files for that system to be differentiated. Since all
ACPI nodes for cs35l41 should have a HID defined, the HID should be a
safe option.

specified"
This reverts commit 8865d22656b4, which caused breakage for platforms
which are not using xgmac2 or gmac4. Only these two cores have the
capability of providing the FIFO sizes from hardware capability fields
(which are provided in priv->dma_cap.[tr]x_fifo_size.)
All other cores can not, which results in these two fields containing
zero. We also have platforms that do not provide a value in
priv->plat->[tr]x_fifo_size, resulting in these also being zero.
This causes the new tests introduced by the reverted commit to fail,
and produce e.g.:
stmmaceth f0804000.eth: Can't specify Rx FIFO size
An example of such a platform which fails is QEMU's npcm750-evb.
This uses dwmac1000 which, as noted above, does not have the capability
to provide the FIFO sizes from hardware.
Therefore, revert the commit to maintain compatibility with the way
the driver used to work.

I feel like we don't do a good enough keeping authors of driver
APIs around. The ethtool code base was very nicely compartmentalized
by Michal. Establish a precedent of creating MAINTAINERS entries
for "sections" of the ethtool API. Use Andrew and cable test as
a sample entry. The entry should ideally cover 3 elements:
a core file, test(s), and keywords. The last one is important
because we intend the entries to cover core code *and* reviews
of drivers implementing given API!

Commit 3ba11e684d16 ("pinctrl: pinconf-generic: print hex value")
unconditionally switched to printing hex values in
pinconf_generic_dump_one(). However, if a dump format is registered for the
dumped pin, the hex value is printed as well. This hex value does not
necessarily correspond 1:1 with the hardware register value (as noted by
commit 3ba11e684d16 ("pinctrl: pinconf-generic: print hex value")). As a
result, user-facing output may include information like:
output drive strength (0x100 uA).
To address this, check if a dump format is registered for the dumped
property, and print the unsigned value instead when applicable.

Memory regions (MR) of type DM (device memory) do not have an associated
umem.
In the __mlx5_ib_dereg_mr() -> mlx5_free_priv_descs() flow, the code
incorrectly takes the wrong branch, attempting to call
dma_unmap_single() on a DMA address that is not mapped.
This results in a WARN [1], as shown below.
The issue is resolved by properly accounting for the DM type and
ensuring the correct branch is selected in mlx5_free_priv_descs().

This patch addresses a potential race condition for a DMABUF MR that can
result in a CQE with an error on the UMR QP.
During the __mlx5_ib_dereg_mr() flow, the following sequence of calls
occurs:
mlx5_revoke_mr()
mlx5r_umr_revoke_mr()
mlx5r_umr_post_send_wait()
At this point, the lkey is freed from the hardware's perspective.
However, concurrently, mlx5_ib_dmabuf_invalidate_cb() might be triggered
by another task attempting to invalidate the MR having that freed lkey.
Since the lkey has already been freed, this can lead to a CQE error,
causing the UMR QP to enter an error state.
To resolve this race condition, the dma_resv_lock() which was hold as
part of the mlx5_ib_dmabuf_invalidate_cb() is now also acquired as part
of the mlx5_revoke_mr() scope.
Upon a successful revoke, we set umem_dmabuf->private which points to
that MR to NULL, preventing any further invalidation attempts on its
lkey.

rxrpc: Call state fixes
Here some call state fixes for AF_RXRPC.
(1) Fix the state of a call to not treat the challenge-response cycle as
part of an incoming call's state set. The problem is that it makes
handling received of the final packet in the receive phase difficult
as that wants to change the call state - but security negotiations may
not yet be complete.
(2) Fix a race between the changing of the call state at the end of the
request reception phase of a service call, recvmsg() collecting the last
data and sendmsg() trying to send the reply before the I/O thread has
advanced the call state.

There's a race in between the rxrpc I/O thread recording the end of the
receive phase of a call and recvmsg() examining the state of the call to
determine whether it has completed.
The problem is that call->_state records the I/O thread's view of the call,
not the application's view (which may lag), so that alone is not
sufficient. To this end, the application also checks whether there is
anything left in call->recvmsg_queue for it to pick up. The call must be
in state RXRPC_CALL_COMPLETE and the recvmsg_queue empty for the call to be
considered fully complete.
In rxrpc_input_queue_data(), the latest skbuff is added to the queue and
then, if it was marked as LAST_PACKET, the state is advanced... But this
is two separate operations with no locking around them.
As a consequence, the lack of locking means that sendmsg() can jump into
the gap on a service call and attempt to send the reply - but then get
rejected because the I/O thread hasn't advanced the state yet.
Simply flipping the order in which things are done isn't an option as that
impacts the client side, causing the checks in rxrpc_kernel_check_life() as
to whether the call is still alive to race instead.
Fix this by moving the update of call->_state inside the skb queue
spinlocked section where the packet is queued on the I/O thread side.
rxrpc's recvmsg() will then automatically sync against this because it has
to take the call->recvmsg_queue spinlock in order to dequeue the last
packet.
rxrpc's sendmsg() doesn't need amending as the app shouldn't be calling it
to send a reply until recvmsg() indicates it has returned all of the
request.

The RXRPC_CALL_SERVER_SECURING state doesn't really belong with the other
states in the call's state set as the other states govern the call's Rx/Tx
phase transition and govern when packets can and can't be received or
transmitted. The "Securing" state doesn't actually govern the reception of
packets and would need to be split depending on whether or not we've
received the last packet yet (to mirror RECV_REQUEST/ACK_REQUEST).
The "Securing" state is more about whether or not we can start forwarding
packets to the application as recvmsg will need to decode them and the
decoding can't take place until the challenge/response exchange has
completed.
Fix this by removing the RXRPC_CALL_SERVER_SECURING state from the state
set and, instead, using a flag, RXRPC_CALL_CONN_CHALLENGING, to track
whether or not we can queue the call for reception by recvmsg() or notify
the kernel app that data is ready. In the event that we've already
received all the packets, the connection event handler will poke the app
layer in the appropriate manner.
Also there's a race whereby the app layer sees the last packet before rxrpc
has managed to end the rx phase and change the state to one amenable to
allowing a reply. Fix this by queuing the packet after calling
rxrpc_end_rx_phase().

In case of tc offload, when user space queries the kernel for tc action
statistics, tc will query the offloaded statistics from device drivers.
Among other statistics, drivers are expected to pass the number of
packets that hit the action since the last query as a 64-bit number.
Unfortunately, tc treats the number of packets as a 32-bit number,
leading to truncation and incorrect statistics when the number of
packets since the last query exceeds 0xffffffff:
$ tc -s filter show dev swp2 ingress
filter protocol all pref 1 flower chain 0
filter protocol all pref 1 flower chain 0 handle 0x1
skip_sw
in_hw in_hw_count 1
action order 1: mirred (Egress Redirect to device swp1) stolen
index 1 ref 1 bind 1 installed 58 sec used 0 sec
Action statistics:
Sent 1133877034176 bytes 536959475 pkt (dropped 0, overlimits 0 requeues 0)
[...]
According to the above, 2111-byte packets were redirected which is
impossible as only 64-byte packets were transmitted and the MTU was
1500.
Fix by treating packets as a 64-bit number:
$ tc -s filter show dev swp2 ingress
filter protocol all pref 1 flower chain 0
filter protocol all pref 1 flower chain 0 handle 0x1
skip_sw
in_hw in_hw_count 1
action order 1: mirred (Egress Redirect to device swp1) stolen
index 1 ref 1 bind 1 installed 61 sec used 0 sec
Action statistics:
Sent 1370624380864 bytes 21416005951 pkt (dropped 0, overlimits 0 requeues 0)
[...]
Which shows that only 64-byte packets were redirected (1370624380864 /
21416005951 = 64).

This reverts commit 3ca459eaba1bf96a8c7878de84fa8872259a01e3.
The blamed commit caused a regression when neither tun->owner nor
tun->group is set. This is intended to be allowed, but now requires
CAP_NET_ADMIN.
Discussion in the referenced thread pointed out that the original
issue that prompted this patch can be resolved in userspace.
The relaxed access control may also make a device accessible when it
previously wasn't, while existing users may depend on it to not be.
This is a clean pure git revert, except for fixing the indentation on
the gid_valid line that checkpatch correctly flagged.

qdisc_tree_reduce_backlog() notifies parent qdisc only if child
qdisc becomes empty, therefore we need to reduce the backlog of the
child qdisc before calling it. Otherwise it would miss the opportunity
to call cops->qlen_notify(), in the case of DRR, it resulted in UAF
since DRR uses ->qlen_notify() to maintain its active list.

Expected behaviour:
In case we reach scheduler's limit, pfifo_tail_enqueue() will drop a
packet in scheduler's queue and decrease scheduler's qlen by one.
Then, pfifo_tail_enqueue() enqueue new packet and increase
scheduler's qlen by one. Finally, pfifo_tail_enqueue() return
`NET_XMIT_CN` status code.
Weird behaviour:
In case we set `sch->limit == 0` and trigger pfifo_tail_enqueue() on a
scheduler that has no packet, the 'drop a packet' step will do nothing.
This means the scheduler's qlen still has value equal 0.
Then, we continue to enqueue new packet and increase scheduler's qlen by
one. In summary, we can leverage pfifo_tail_enqueue() to increase qlen by
one and return `NET_XMIT_CN` status code.
The problem is:
Let's say we have two qdiscs: Qdisc_A and Qdisc_B.
- Qdisc_A's type must have '->graft()' function to create parent/child relationship.
Let's say Qdisc_A's type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`.
- Qdisc_B's type is pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`.
- Qdisc_B is configured to have `sch->limit == 0`.
- Qdisc_A is configured to route the enqueued's packet to Qdisc_B.
Enqueue packet through Qdisc_A will lead to:
- hfsc_enqueue(Qdisc_A) -> pfifo_tail_enqueue(Qdisc_B)
- Qdisc_B->q.qlen += 1
- pfifo_tail_enqueue() return `NET_XMIT_CN`
- hfsc_enqueue() check for `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` => hfsc_enqueue() don't increase qlen of Qdisc_A.
The whole process lead to a situation where Qdisc_A->q.qlen == 0 and Qdisc_B->q.qlen == 1.
Replace 'hfsc' with other type (for example: 'drr') still lead to the same problem.
This violate the design where parent's qlen should equal to the sum of its childrens'qlen.
Bug impact: This issue can be used for user->kernel privilege escalation when it is reachable.

The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE
by closing the connection with unread bytes in the receive queue.
The xdisconnect() helper was used to stop the connection, but it does
more than that: it will shut it down, then wait before reconnecting to
the same address. This causes the mptcp_join's "fastclose test" to fail
all the time.
This failure is due to a recent change, with commit 218cc166321f
("selftests: mptcp: avoid spurious errors on disconnect"), but that went
unnoticed because the test is currently ignored. The recent modification
only shown an existing issue: xdisconnect() doesn't need to be used
here, only the shutdown() part is needed.

Starting with Rust 1.86.0 (currently in nightly, to be released on
2025-04-03), the `missing_abi` lint is warn-by-default [1]:
error: extern declarations without an explicit ABI are deprecated
--> rust/doctests_kernel_generated.rs:3158:1

3158 | extern {
| ^^^^^^ help: explicitly specify the C ABI: `extern "C"`

= note: `-D missing-abi` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(missing_abi)]`
Thus clean it up.

There seems to have been merge skew between commit b2c261fa8629 ("rust:
kbuild: expand rusttest target for macros") and commit 0730422bced5
("rust: use host dylib naming convention to support macOS") ; the latter
replaced `libmacros.so` with `$(libmacros_name)` and the former added an
instance of `libmacros.so`. The former was not yet applied when the
latter was sent, resulting in a stray `libmacros.so`. Replace the stray
with `$(libmacros_name)` to allow `rusttest` to build on macOS.

Commit 088984c8d54c ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM
handler and context") added unnecessary strict handler address checks,
causing the PRM module to fail in translating memory error addresses.
Both static data buffer address and ACPI parameter buffer address may
be NULL if they are not needed, as described in section 4.1.2 PRM Handler
Information Structure of Platform Runtime Mechanism specification [1].
Here are two examples from real hardware:

The Eluktronics MECH-17 (GM7RG7N) needs IRQ overriding for the
keyboard to work.
Adding a DMI_MATCH entry for this laptop model makes the internal
keyboard function normally.
