The byte queue limits (BQL) mechanism is intended to move queuing from
the driver to the network stack in order to reduce latency caused by
excessive queuing in hardware. However, when transmitting or redirecting
a packet using generic XDP, the qdisc layer is bypassed and there are no
additional queues. Since netif_xmit_stopped() also takes BQL limits into
account, but without having any alternative queuing, packets are
silently dropped.
This patch modifies the drop condition to only consider cases when the
driver itself cannot accept any more packets. This is analogous to the
condition in __dev_direct_xmit(). Dropped packets are also counted on
the device.
Bypassing the qdisc layer in the generic XDP TX path means that XDP
packets are able to starve other packets going through a qdisc, and
DDOS attacks will be more effective. In-driver-XDP use dedicated TX
queues, so they do not have this starvation issue.

This reverts commit 284b4d93daee56dff3e10029ddf2e03227f50dbf.
When using TLS device offload and coming from tls_device_reencrypt()
flow, -EBADMSG error in tls_do_decryption() should not be counted
towards the TLSTlsDecryptError counter.
Move the counter increase back to the decrypt_internal() call site in
decrypt_skb_update().
This also fixes an issue where:
if (n_sgin < 1)
return -EBADMSG;
Errors in decrypt_internal() were not counted after the cited patch.

mptcp: Path manager fixes for 5.19
The MPTCP userspace path manager is new in 5.19, and these patches fix
some issues in that new code.
Patches 1-3 fix path manager locking issues.
Patches 4 and 5 allow userspace path managers to change priority of
established subflows using the existing MPTCP_PM_CMD_SET_FLAGS generic
netlink command. Includes corresponding self test update.
Patches 6 and 7 fix accounting of available endpoint IDs and the

When setting up a subflow's flags for sending MP_PRIO MPTCP options, the
subflow socket lock was not held while reading and modifying several
struct members that are also read and modified in mptcp_write_options().
Acquire the subflow socket lock earlier and send the MP_PRIO ACK with
that lock already acquired. Add a new variant of the
mptcp_subflow_send_ack() helper to use with the subflow lock held.

The in-kernel path manager code for changing subflow flags acquired both
the msk socket lock and the PM lock when possibly changing the "backup"
and "fullmesh" flags. mptcp_pm_nl_mp_prio_send_ack() does not access
anything protected by the PM lock, and it must release and reacquire
the PM lock.
By pushing the PM lock to where it is needed in mptcp_pm_nl_fullmesh(),
the lock is only acquired when the fullmesh flag is changed and the
backup flag code no longer has to release and reacquire the PM lock. The
change in locking context requires the MIB update to be modified - move
that to a better location instead.
This change also makes it possible to call
mptcp_pm_nl_mp_prio_send_ack() for the userspace PM commands without
manipulating the in-kernel PM lock.

Referenced commit prepared the code for upcoming extension that allows mlx5

regard to existing matchall classifier offload validation should be

Offloading police with action TC_ACT_UNSPEC was erroneously disabled even
though it was supported by mlx5 matchall offload implementation, which
didn't verify the action type but instead assumed that any single police
action attached to matchall classifier is a 'continue' action. Lack of
action type check made it non-obvious what mlx5 matchall implementation
actually supports and caused implementers and reviewers of referenced

Instead of counting the child nodes in the device tree, hardcode the
number of ports in the driver itself. The counting won't work at all
if an ethernet port is marked as disabled, e.g. because it is not
connected on the board at all.
It turns out that the LAN9662 and LAN9668 use the same switching IP
with the same synthesis parameters. The only difference is that the
output ports are not connected. Thus, we can just hardcode the
number of physical ports to 8.

`cancel_work_sync(&hdev->power_on)` was moved to hci_dev_close_sync in
commit [1] to ensure that power_on work is canceled after HCI interface
down.
But, in certain cases power_on work function may call hci_dev_close_sync
itself: hci_power_on -> hci_dev_do_close -> hci_dev_close_sync ->
cancel_work_sync(&hdev->power_on), causing deadlock. In particular, this
happens when device is rfkilled on boot. To avoid deadlock, move
power_on work canceling out of hci_dev_do_close/hci_dev_close_sync.
Deadlock introduced by commit [1] was reported in [2,3] as broken
suspend. Suspend did not work because `hdev->req_lock` held as result of
`power_on` work deadlock. In fact, other BT features were not working.
It was not observed when testing [1] since it was verified without
rfkill in place.
NOTE: It is not needed to cancel power_on work from other places where
hci_dev_do_close/hci_dev_close_sync is called in case:
* Requests were serialized due to `hdev->req_workqueue`. The power_on
work is first in that workqueue.
* hci_rfkill_set_block which won't close device anyway until HCI_SETUP
is on.
* hci_sock_release which runs after hci_sock_bind which ensures
HCI_SETUP was cleared.
As result, behaviour is the same as in pre-dd06ed7 commit, except
power_on work cancel added to hci_dev_close.

Pull xen security fixes from Juergen Gross:
- XSA-403 (4 patches for blkfront and netfront drivers):
Linux Block and Network PV device frontends don't zero memory regions
before sharing them with the backend (CVE-2022-26365,
CVE-2022-33740). Additionally the granularity of the grant table
doesn't allow sharing less than a 4K page, leading to unrelated data
residing in the same 4K page as data shared with a backend being
accessible by such backend (CVE-2022-33741, CVE-2022-33742).
- XSA-405 (1 patch for netfront driver, only 5.10 and newer):
While adding logic to support XDP (eXpress Data Path), a code label
was moved in a way allowing for SKBs having references (pointers)
retained for further processing to nevertheless be freed.
- XSA-406 (1 patch for Arm specific dom0 code):
When mapping pages of guests on Arm, dom0 is using an rbtree to keep
track of the foreign mappings.
Updating of that rbtree is not always done completely with the
related lock held, resulting in a small race window, which can be
used by unprivileged guests via PV devices to cause inconsistencies
of the rbtree. These inconsistencies can lead to Denial of Service
(DoS) of dom0, e.g. by causing crashes or the inability to perform
further mappings of other guests' memory pages.

The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature. Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().
This patch fixes it by calling snd_card_free() manually on the error
from the probe callback.

As mentioned in the blamed commit, flood_unicast_test() works by
checking the match count on a tc filter placed on the receiving
interface.
But the second host interface (host2_if) has no interest in receiving a
packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even
before the ingress tc filter gets to be executed. So we will incorrectly
get the message "Packet was not flooded when should", when in fact, the
packet was flooded as expected but dropped due to an unrelated reason,
at some other layer on the receiving side.
Force h2 to accept this packet by temporarily placing it in promiscuous
mode. Alternatively we could either deliver to its MAC address or use
tcpdump_start, but this has the fewest complications.
This fixes the "flooding" test from bridge_vlan_aware.sh and
bridge_vlan_unaware.sh, which calls flood_test from the lib.

ASoC: Fixes for v5.19
A collection of fixes for v5.19, quite large but nothing major - a good
chunk of it is more stuff that was identified by mixer-test regarding
event generation.

The patch applies the same quirks used for SC-01 at firmware v1.1.0 to
the ones running v1.0.0, with respect to hard-coded sample rates.
I got two more units and successfully tested the patch series with both
firmwares.
The support is now complete (not accounting ASIO).

Fiero SC-01 is a USB sound card with two mono inputs and a single
stereo output. The inputs are composed into a single stereo stream.
The device uses a vendor-provided driver on Windows and does not work
at all without it. The driver mostly provides ASIO functionality, but
also alters the way the sound card is queried for sample rates and
clocks.
ALSA queries those failing with an EPIPE (same as Windows 10 does).
Presumably, the vendor-provided driver does not query it at all, simply
matching by VID:PID. Thus, I consider this a buggy firmware and adhere
to a set of fixed endpoint quirks instead.
The soundcard has an internal clock. Implicit feedback mode is required
for the playback.
I have updated my device to v1.1.0 from a Windows 10 VM using a vendor-
provided binary prior to the development, hoping for it to just begin
working. The device provides no obvious way to downgrade the firmware,
and regardless, there's no binary available for v1.0.0 anyway.
Thus, I will be getting another unit to extend the patch with support
for that. Expected to be a simple copy-paste of the existing one,
though.
There were no previous reports of that device in context of Linux
anywhere. Other issues have been reported though, but that's out of the
scope.

In mcp251xfd_register_get_dev_id() the device ID register is read with
handcrafted SPI transfers. As all registers, this register is in
little endian. Further it is not naturally aligned in struct
mcp251xfd_map_buf_nocrc::data. However after the transfer the register
content is converted from big endian to CPU endianness not taking care
of being unaligned.
Fix the conversion by converting from little endian to CPU endianness
taking the unaligned source into account.
Side note: So far the register content is 0x0 on all mcp251xfd
compatible chips, and is only used for an informative printk.

dev_id
The device ID register is 32 bits wide. The driver uses incorrectly
the size of a pointer to a u32 to calculate the length of the SPI
transfer. This results in a read of 2 registers on 64 bit platforms.
This is no problem on the Linux side, as the RX buffer of the SPI
transfer is large enough. In the mpc251xfd chip this results in the
read of an undocumented register. So far no problems were observed.
Fix the length of the SPI transfer to read the device ID register
only.

In commit 169d00a25658 ("can: mcp251xfd: add TX IRQ coalescing
support") software based TX coalescing was added to the driver. The
key idea is to keep the TX complete IRQ disabled for some time after
processing it and re-enable later by a hrtimer. When bringing the
interface down, this timer has to be stopped.
Add the missing hrtimer_cancel() of the tx_irq_time hrtimer to
mcp251xfd_stop().

TBC register
The mcp251xfd compatible chips have an erratum ([1], [2]), where the
received CRC doesn't match the calculated CRC. In commit
c7eb923c3caf ("can: mcp251xfd: mcp251xfd_regmap_crc_read(): work
around broken CRC on TBC register") the following workaround was
implementierend.
- If a CRC read error on the TBC register is detected and the first
byte is 0x00 or 0x80, the most significant bit of the first byte is
flipped and the CRC is calculated again.
- If the CRC now matches, the _original_ data is passed to the reader.
For now we assume transferred data was OK.
New investigations and simulations indicate that the CRC send by the
device is calculated on correct data, and the data is incorrectly
received by the SPI host controller.
Use flipped instead of original data and update workaround description
in mcp251xfd_regmap_crc_read().

The firmware of M32C based Leaf devices expects bittiming parameters
calculated for 16MHz clock. Since we use the actual clock frequency of
the device, the device may end up with wrong bittiming parameters,
depending on user requested parameters.
This regression affects M32C based Leaf devices with non-16MHz clock.

During a reset, there may have been transmits in flight that are no
longer valid and cannot be fulfilled. Resetting and clearing the
queues is insufficient; each skb also needs to be explicitly freed
so that upper levels are not left waiting for confirmation of a
transmit that will never happen. If this happens frequently enough,
the apparent backlog will cause TCP to begin "congestion control"
unnecessarily, culminating in permanently decreased throughput.

In commit 1be37d3b0414 ("can: m_can: fix periph RX path: use
rx-offload to ensure skbs are sent from softirq context") the RX path
for peripheral devices was switched to RX-offload.
Received CAN frames are pushed to RX-offload together with a
timestamp. RX-offload is designed to handle overflows of the timestamp
correctly, if 32 bit timestamps are provided.
The timestamps of m_can core are only 16 bits wide. So this patch
shifts them to full 32 bit before passing them to RX-offload.

The gs_usb driver appears to suffer from a malady common to many USB
CAN adapter drivers in that it performs usb_alloc_coherent() to
allocate a number of USB request blocks (URBs) for RX, and then later
relies on usb_kill_anchored_urbs() to free them, but this doesn't
actually free them. As a result, this may be leaking DMA memory that's
been used by the driver.
This commit is an adaptation of the techniques found in the esd_usb2
driver where a similar design pattern led to a memory leak. It
explicitly frees the RX URBs and their DMA memory via a call to
usb_free_coherent(). Since the RX URBs were allocated in the
gs_can_open(), we remove them in gs_can_close() rather than in the
disconnect function as was done in esd_usb2.
For more information, see the 928150fad41b ("can: esd_usb2: fix memory
leak").
