When both supported and previous version have the same major version,
and the firmwares are missing, the driver ends in a loop requesting the
same (previous) version over and over again:

...
Fix this by inverting the check to that we aren't yet at the previous
version, and also check the minor version.
This also catches the case where both versions are the same, as it was
after commit bb5dbf2cc64d ("net: marvell: prestera: add firmware v4.0
support").
With this fix applied:
[ 88.499622] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.1.img firmware, fall-back to previous 4.0 version

In the cited commit, new type of FS_TYPE_PRIO_CHAINS fs_prio was added
to support multiple parallel namespaces for multi-chains. And we skip
all the flow tables under the fs_node of this type unconditionally,
when searching for the next or previous flow table to connect for a
new table.
As this search function is also used for find new root table when the
old one is being deleted, it will skip the entire FS_TYPE_PRIO_CHAINS
fs_node next to the old root. However, new root table should be chosen
from it if there is any table in it. Fix it by skipping only the flow
tables in the same FS_TYPE_PRIO_CHAINS fs_node when finding the
closest FT for a fs_node.
Besides, complete the connecting from FTs of previous priority of prio
because there should be multiple prevs after this fs_prio type is
introduced. And also the next FT should be chosen from the first flow
table next to the prio in the same FS_TYPE_PRIO_CHAINS fs_prio, if
this prio is the first child.

As find_closest_ft_recursive is called to find the closest FT, the
first parameter of find_closest_ft can be changed from fs_prio to
fs_node. Thus this function is extended to find the closest FT for the
nodes of any type, not only prios, but also the sub namespaces.

Using brcmfmac with 6.5-rc3 on a brcmfmac43241b4-sdio triggers
a backtrace caused by the following field-spanning warning:
memcpy: detected field-spanning write (size 120) of single field
"¶ms_le->channel_list[0]" at
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:1072 (size 2)
The driver still works after this warning. The warning was introduced by the
new field-spanning write checks which were enabled recently.
Fix this by replacing the channel_list[1] declaration at the end of
the struct with a flexible array declaration.
Most users of struct brcmf_scan_params_le calculate the size to alloc
using the size of the non flex-array part of the struct + needed extra
space, so they do not care about sizeof(struct brcmf_scan_params_le).
brcmf_notify_escan_complete() however uses the struct on the stack,
expecting there to be room for at least 1 entry in the channel-list
to store the special -1 abort channel-id.
To make this work use an anonymous union with a padding member
added + the actual channel_list flexible array.

dev_close() and dev_open() are issued to change the interface state to DOWN
or UP (dev->flags IFF_UP). When the netdev is set DOWN it loses e.g its
Ipv6 addresses and routes. We don't want this in cases of device recovery
(triggered by hardware or software) or when the qeth device is set
offline.
Setting a qeth device offline or online and device recovery actions call
netif_device_detach() and/or netif_device_attach(). That will reset or
set the LOWER_UP indication i.e. change the dev->state Bit
__LINK_STATE_PRESENT. That is enough to e.g. cause bond failovers, and
still preserves the interface settings that are handled by the network
stack.
Don't call dev_open() nor dev_close() from the qeth device driver. Let the
network stack handle this.

Commit 66b2c338adce initializes the "sk_uid" field in the protocol socket
(struct sock) from the "/dev/tapX" device node's owner UID. Per original
commit 86741ec25462 ("net: core: Add a UID field to struct sock.",
2016-11-04), that's wrong: the idea is to cache the UID of the userspace
process that creates the socket. Commit 86741ec25462 mentions socket() and
accept(); with "tap", the action that creates the socket is
open("/dev/tapX").
Therefore the device node's owner UID is irrelevant. In most cases,
"/dev/tapX" will be owned by root, so in practice, commit 66b2c338adce has
no observable effect:
- before, "sk_uid" would be zero, due to undefined behavior
(CVE-2023-1076),
- after, "sk_uid" would be zero, due to "/dev/tapX" being owned by root.

Commit a096ccca6e50 initializes the "sk_uid" field in the protocol socket
(struct sock) from the "/dev/net/tun" device node's owner UID. Per
original commit 86741ec25462 ("net: core: Add a UID field to struct
sock.", 2016-11-04), that's wrong: the idea is to cache the UID of the
userspace process that creates the socket. Commit 86741ec25462 mentions
socket() and accept(); with "tun", the action that creates the socket is
open("/dev/net/tun").
Therefore the device node's owner UID is irrelevant. In most cases,
"/dev/net/tun" will be owned by root, so in practice, commit a096ccca6e50
has no observable effect:
- before, "sk_uid" would be zero, due to undefined behavior
(CVE-2023-1076),
- after, "sk_uid" would be zero, due to "/dev/net/tun" being owned by root.
What matters is the (fs)UID of the process performing the open(), so cache
that in "sk_uid".

During system resume, ata_port_pm_resume() triggers ata EH to
1) Resume the controller
2) Reset and rescan the ports
3) Revalidate devices
This EH execution is started asynchronously from ata_port_pm_resume(),
which means that when sd_resume() is executed, none or only part of the
above processing may have been executed. However, sd_resume() issues a
START STOP UNIT to wake up the drive from sleep mode. This command is
translated to ATA with ata_scsi_start_stop_xlat() and issued to the
device. However, depending on the state of execution of the EH process
and revalidation triggerred by ata_port_pm_resume(), two things may
happen:
1) The START STOP UNIT fails if it is received before the controller has
been reenabled at the beginning of the EH execution. This is visible
with error messages like:
ata10.00: device reported invalid CHS sector 0
sd 9:0:0:0: [sdc] Start/Stop Unit failed: Result: hostbyte=DID_OK driverbyte=DRIVER_OK
sd 9:0:0:0: [sdc] Sense Key : Illegal Request [current]
sd 9:0:0:0: [sdc] Add. Sense: Unaligned write command
sd 9:0:0:0: PM: dpm_run_callback(): scsi_bus_resume+0x0/0x90 returns -5
sd 9:0:0:0: PM: failed to resume async: error -5
2) The START STOP UNIT command is received while the EH process is
on-going, which mean that it is stopped and must wait for its
completion, at which point the command is rather useless as the drive
is already fully spun up already. This case results also in a
significant delay in sd_resume() which is observable by users as
the entire system resume completion is delayed.
Given that ATA devices will be woken up by libata activity on resume,
sd_resume() has no need to issue a START STOP UNIT command, which solves
the above mentioned problems. Do not issue this command by introducing
the new scsi_device flag no_start_on_resume and setting this flag to 1
in ata_scsi_dev_config(). sd_resume() is modified to issue a START STOP
UNIT command only if this flag is not set.

Due to rbd_try_acquire_lock() effectively swallowing all but
EBLOCKLISTED error from rbd_try_lock() ("request lock anyway") and
rbd_request_lock() returning ETIMEDOUT error not only for an actual
notify timeout but also when the lock owner doesn't respond, a busy
loop inside of rbd_acquire_lock() between rbd_try_acquire_lock() and
rbd_request_lock() is possible.
Requesting the lock on EBUSY error (returned by get_lock_owner_info()
if an incompatible lock or invalid lock owner is detected) makes very
little sense. The same goes for ETIMEDOUT error (might pop up pretty
much anywhere if osd_request_timeout option is set) and many others.
Just fail I/O requests on rbd_dev->acquiring_list immediately on any
error from rbd_try_lock().

As documented in acd7aaf51b20 ("netsec: ignore 'phy-mode' device
property on ACPI systems") the SocioNext SynQuacer platform ships with
firmware defining the PHY mode as RGMII even though the physical
configuration of the PHY is for TX and RX delays. Since bbc4d71d63549bc
("net: phy: realtek: fix rtl8211e rx/tx delay config") this has caused
misconfiguration of the PHY, rendering the network unusable.
This was worked around for ACPI by ignoring the phy-mode property but
the system is also used with DT. For DT instead if we're running on a
SynQuacer force a working PHY mode, as well as the standard EDK2
firmware with DT there are also some of these systems that use u-boot
and might not initialise the PHY if not netbooting. Newer firmware
imagaes for at least EDK2 are available from Linaro so print a warning
when doing this.

Infinite waits for completion of GPU activity have been observed in CI,
mostly inside __i915_active_wait(), triggered by igt@gem_barrier_race or
igt@perf@stress-open-close. Root cause analysis, based of ftrace dumps
generated with a lot of extra trace_printk() calls added to the code,
revealed loops of request dependencies being accidentally built,
preventing the requests from being processed, each waiting for completion
of another one's activity.
After we substitute a new request for a last active one tracked on a
timeline, we set up a dependency of our new request to wait on completion
of current activity of that previous one. While doing that, we must take
care of keeping the old request still in memory until we use its
attributes for setting up that await dependency, or we can happen to set
up the await dependency on an unrelated request that already reuses the
memory previously allocated to the old one, already released. Combined
with perf adding consecutive kernel context remote requests to different
user context timelines, unresolvable loops of await dependencies can be
built, leading do infinite waits.
We obtain a pointer to the previous request to wait upon when we
substitute it with a pointer to our new request in an active tracker,
e.g. in intel_timeline.last_request. In some processing paths we protect
that old request from being freed before we use it by getting a reference
to it under RCU protection, but in others, e.g. __i915_request_commit()
-> __i915_request_add_to_timeline() -> __i915_request_ensure_ordering(),
we don't. But anyway, since the requests' memory is SLAB_FAILSAFE_BY_RCU,
that RCU protection is not sufficient against reuse of memory.
We could protect i915_request's memory from being prematurely reused by
calling its release function via call_rcu() and using rcu_read_lock()
consequently, as proposed in v1. However, that approach leads to
significant (up to 10 times) increase of SLAB utilization by i915_request
SLAB cache. Another potential approach is to take a reference to the
previous active fence.
When updating an active fence tracker, we first lock the new fence,
substitute a pointer of the current active fence with the new one, then we
lock the substituted fence. With this approach, there is a time window
after the substitution and before the lock when the request can be
concurrently released by an interrupt handler and its memory reused, then
we may happen to lock and return a new, unrelated request.
Always get a reference to the current active fence first, before
replacing it with a new one. Having it protected from premature release
and reuse, lock it and then replace with the new one but only if not
yet signalled via a potential concurrent interrupt nor replaced with
another one by a potential concurrent thread, otherwise retry, starting
from getting a reference to the new current one. Adjust users to not
get a reference to the previous active fence themselves and always put the
reference got by __i915_active_fence_set() when no longer needed.
v3: Fix lockdep splat reports and other issues caused by incorrect use of
try_cmpxchg() (use (cmpxchg() != prev) instead)
v2: Protect request's memory by getting a reference to it in favor of
delegating its release to call_rcu() (Chris)

Remove also VD1, VD3 and VE1 registers that don't exist and add
BCS0 and CCS0.

Msg length should be obtained from value written to AUX_CH_CTL register
rather than from enum type of the register.
Commit 0cad796a2269 ("drm/i915: Use REG_BIT() & co. for AUX CH registers")
incorrectly calculates the msg_length from reg type and yields below
warning in intel_gvt_i2c_handle_aux_ch_write():
"i915 0000:00:02.0: drm_WARN_ON(msg_length != 4)".

The two mbox-related mutexes are destroyed in octep_ctrl_mbox_uninit(),
but the corresponding mutex_init calls were missing.
A "DEBUG_LOCKS_WARN_ON(lock->magic != lock)" warning was emitted with
CONFIG_DEBUG_MUTEXES on.
Initialize the two mutexes in octep_ctrl_mbox_init().

Similarly to other recently fixed drivers make sure we don't
try to access XDP or page pool APIs when NAPI budget is 0.
NAPI budget of 0 may mean that we are in netpoll.
This may result in running software IRQs in hard IRQ context,
leading to deadlocks or crashes.
To make sure bnapi->tx_pkts don't get wiped without handling
the events, move clearing the field into the handler itself.
Remember to clear tx_pkts after reset (bnxt_enable_napi())
as it's technically possible that netpoll will accumulate
some tx_pkts and then a reset will happen, leaving tx_pkts
out of sync with reality.

During qdisc create/delete, it is necessary to rebuild the queue
of VSIs. An error occurred because the VSIs created by RDMA were
still active.
Added check if RDMA is active. If yes, it disallows qdisc changes
and writes a message in the system logs.
