When kcalloc() for ft->g succeeds but kvzalloc() for in fails,
fs_any_create_groups() will free ft->g. However, its caller
fs_any_create_table() will free ft->g again through calling
mlx5e_destroy_flow_table(), which will lead to a double-free.
Fix this by setting ft->g to NULL in fs_any_create_groups().

When `in` allocated by kvzalloc fails, arfs_create_groups will free
ft->g and return an error. However, arfs_create_table, the only caller of
arfs_create_groups, will hold this error and call to
mlx5e_destroy_flow_table, in which the ft->g will be freed again.

XFRM stack doesn't prevent from users to configure replay window
in TX side and strongswan sets replay_window to be 1. It causes
to failures in validation logic when trying to offload the SA.

All ConnectX devices have software parsing capability enabled, but it is
more correct to set allow_swp only if capability exists, which for IPsec

When FW provides ICM addresses for drop RX/TX, the provided capability
is 64 bits that contain its GVMI as well as the ICM address itself.
In case of TX DROP this GVMI is different from the GVMI that the
domain is operating on.
This patch fixes the action to use these GVMI IDs, as provided by FW.

The cited change refactored mlx5e_tc_del_fdb_peer_flow() to only clear DUP
flag when list of peer flows has become empty. However, if any concurrent
user holds a reference to a peer flow (for example, the neighbor update
workqueue task is updating peer flow's parent encap entry concurrently),
then the flow will not be removed from the peer list and, consecutively,
DUP flag will remain set. Since mlx5e_tc_del_fdb_peers_flow() calls
mlx5e_tc_del_fdb_peer_flow() for every possible peer index the algorithm
will try to remove the flow from eswitch instances that it has never peered
with causing either NULL pointer dereference when trying to remove the flow
peer list head of peer_index that was never initialized or a warning if the
list debug config is enabled[0].
Fix the issue by always removing the peer flow from the list even when not
releasing the last reference to it.

The processing of traffic in hairpin queues occurs in HW/FW and does not
involve the cpus, hence the upper bound on max num channels does not
apply to them. Using this bound for the hairpin RQT max_table_size is
wrong. It could be too small, and cause the error below [1]. As the
RQT size provided on init does not get modified later, use the same
value for both actual and max table sizes.

Indirection (*) is of lower precedence than postfix increment (++). Logic
in napi_poll context would cause an out-of-bound read by first increment
the pointer address by byte address space and then dereference the value.
Rather, the intended logic was to dereference first and then increment the
underlying value.

The cited commit moved the code of mlx5e_create_tises() and changed the
loop to create TISes over MLX5_MAX_PORTS constant value, instead of
getting the correct lag ports supported by the device, which can cause
FW errors on devices with less than MLX5_MAX_PORTS ports.
Change that back to mlx5e_get_num_lag_ports(mdev).
Also IPoIB interfaces create there own TISes, they don't use the eth
TISes, pass a flag to indicate that.
This fixes the following errors that might appear in kernel log:

The ASM1166 SATA host controller always reports wrongly,
that it has 32 ports. But in reality, it only has six ports.
This seems to be a hardware issue, as all tested ASM1166

Example output: ahci 0000:09:00.0: AHCI 0001.0301
32 slots 32 ports 6 Gbps 0xffffff3f impl SATA mode.
By adjusting the port_map, the count is limited to six ports.

Current code in netvsc_drv_init() incorrectly assumes that PAGE_SIZE
is 4 Kbytes, which is wrong on ARM64 with 16K or 64K page size. As a
result, the default VMBus ring buffer size on ARM64 with 64K page size
is 8 Mbytes instead of the expected 512 Kbytes. While this doesn't break
anything, a typical VM with 8 vCPUs and 8 netvsc channels wastes 120
Mbytes (8 channels * 2 ring buffers/channel * 7.5 Mbytes/ring buffer).
Unfortunately, the module parameter specifying the ring buffer size
is in units of 4 Kbyte pages. Ideally, it should be in units that
are independent of PAGE_SIZE, but backwards compatibility prevents
changing that now.
Fix this by having netvsc_drv_init() hardcode 4096 instead of using
PAGE_SIZE when calculating the ring buffer size in bytes. Also
use the VMBUS_RING_SIZE macro to ensure proper alignment when running
with page size larger than 4K.

This reverts commit b34ab3527b9622ca4910df24ff5beed5aa66c6b5.
Using skb_ensure_writable_head_tail without a call to skb_unshare causes
the MACsec stack to operate on the original skb rather than a copy in the
macsec_encrypt path. This causes the buffer to be exceeded in space, and
leads to warnings generated by skb_put operations. Opting to revert this
change since skb_copy_expand is more efficient than
skb_ensure_writable_head_tail followed by a call to skb_unshare.

In the existing implementation, when executing interleaved write and read
operations in the ISR for a transfer length greater than the FIFO size,
the TXFIFO write precedes the RXFIFO read. Consequently, the initially
received data in the RXFIFO is pushed out and lost, leading to a failure
in data integrity. To address this issue, reverse the order of interleaved
operations and conduct the RXFIFO read followed by the TXFIFO write.

Currently, both ATA_LPM_UNKNOWN (0) and ATA_LPM_MAX_POWER (1) displays
as "max_performance" in sysfs.
This is quite misleading as they are not the same.
For ATA_LPM_UNKNOWN, ata_eh_set_lpm() will not be called at all,
leaving the configuration in unknown state.
For ATA_LPM_MAX_POWER, ata_eh_set_lpm() is called, and setting the
policy to ATA_LPM_MAX_POWER.
This also matches the description of the SATA_MOBILE_LPM_POLICY Kconfig:
0 => Keep firmware settings
1 => Maximum performance
Thus, update the sysfs description for ATA_LPM_UNKNOWN to match reality.
While at it, update libata.h to mention that the ascii descriptions
are in libata-sata.c and not in libata-scsi.c.

CXL 3.1 Section 3.1.1 states:
"A Function on a CXL device must not generate INTx messages if
that Function participates in CXL.cache protocol or CXL.mem
protocols."
The generic CXL memory driver only supports devices which use the
CXL.mem protocol. The current driver attempts to allocate MSI/MSI-X
vectors in anticipation of their need for mailbox interrupts or event
processing. However, the above requirement does not require a device to
support interrupts, only that they use MSI/MSI-X. For example, a device
may disable mailbox interrupts and either be configured for firmware
first or skip event processing and function.
Dave Larsen reported that the following Intel / Agilex card does not
support interrupts on function 0.
CXL: Intel Corporation Device 0ddb (rev 01) (prog-if 10 [CXL Memory Device (CXL 2.x)])
Rather than fail device probe if interrupts are not supported; flag that
irqs are not enabled and avoid features which require interrupts.
Emit messages appropriate for the situation to aid in debugging should
device behavior be unexpected due to a failure to allocate vectors.
Note that it is possible for a device to have host based event
processing through polling. However, the driver does not support
polling and it is not anticipated to be generally required. Leave that
functionality to a future patch if such a device comes along.

Pull xen netback fix from Juergen Gross:
"Transmit requests in Xen's virtual network protocol can consist of
multiple parts. While not really useful, except for the initial part
any of them may be of zero length, i.e. carry no data at all.
Besides a certain initial portion of the to be transferred data, these
parts are directly translated into what Linux calls SKB fragments.
Such converted request parts can, when for a particular SKB they are
all of length zero, lead to a de-reference of NULL in core networking
code"

Similar to commit 26db46bc9c67 ("drm/bridge: parade-ps8640: Ensure bridge
is suspended in .post_disable()"). Add a mutex to ensure that aux transfer
won't race with atomic_disable by holding the PM reference and prevent
the bridge from suspend.
Also we need to use pm_runtime_put_sync_suspend() to suspend the bridge
instead of idle with pm_runtime_put_sync().

Turns out this "SoC" side controller does not support certain commands,
such as reading chip JEDEC ID, so the controller is pretty much unusable
in Linux. We should be using the "PCH" side controller instead. For this

On systems using HWP, if a given frequency is equal to the maximum turbo
frequency or the maximum non-turbo frequency, the HWP performance level
corresponding to it is already known and can be used directly without
any computation.
Accordingly, adjust the code to use the known HWP performance levels in
the cases mentioned above.
This also helps to avoid limiting CPU capacity artificially in some
cases when the BIOS produces the HWP_CAP numbers using a different
E-core-to-P-core performance scaling factor than expected by the kernel.
