This patch adds the new struct ieee80211_rate_status and replaces
'struct rate_info *rate' in ieee80211_tx_status with pointer and length
annotation.
The struct ieee80211_rate_status allows to:
(1) receive tx power status feedback for transmit power control (TPC)
per packet or packet retry
(2) dynamic mapping of wifi chip specific multi-rate retry (mrr)
chains with different lengths
(3) increase the limit of annotatable rate indices to support
IEEE802.11ac rate sets and beyond
ieee80211_tx_info, control and status buffer, and ieee80211_tx_rate
cannot be used to achieve these goals due to fixed size limitations.
Our new struct contains a struct rate_info to annotate the rate that was
used, retry count of the rate and tx power. It is intended for all
information related to RC and TPC that needs to be passed from driver to
mac80211 and its RC/TPC algorithms like Minstrel_HT. It corresponds to
one stage in an mrr. Multiple subsequent instances of this struct can be
included in struct ieee80211_tx_status via a pointer and a length variable.
Those instances can be allocated on-stack. The former reference to a single
instance of struct rate_info is replaced with our new annotation.
An extension is introduced to struct ieee80211_hw. There are two new
members called 'tx_power_levels' and 'max_txpwr_levels_idx' acting as a
tx power level table. When a wifi device is registered, the driver shall
supply all supported power levels in this list. This allows to support
several quirks like differing power steps in power level ranges or
alike. TPC can use this for algorithm and thus be designed more abstract
instead of handling all possible step widths individually.
Further mandatory changes in status.c, mt76 and ath11k drivers due to the
removal of 'struct rate_info *rate' are also included.
status.c already uses the information in ieee80211_tx_status->rate in
radiotap, this is now changed to use ieee80211_rate_status->rate_idx.
mt76 driver already uses struct rate_info to pass the tx rate to status
path. The new members of the ieee80211_tx_status are set to NULL and 0
because the previously passed rate is not relevant to rate control and
accurate information is passed via tx_info->status.rates.
For ath11k, the txrate can be passed via this struct because ath11k uses
firmware RC and thus the information does not interfere with software RC.

In IPv4 setting the "disable_policy" flag on a device means no policy
should be enforced for traffic originating from the device. This was
implemented by seting the DST_NOPOLICY flag in the dst based on the
originating device.
However, dsts are cached in nexthops regardless of the originating
devices, in which case, the DST_NOPOLICY flag value may be incorrect.
Consider the following setup:
+------------------------------+
| ROUTER |
+-------------+ | +-----------------+ |
| ipsec src |----|-|ipsec0 | |
+-------------+ | |disable_policy=0 | +----+ |
| +-----------------+ |eth1|-|-----
+-------------+ | +-----------------+ +----+ |
| noipsec src |----|-|eth0 | |
+-------------+ | |disable_policy=1 | |
| +-----------------+ |
+------------------------------+
Where ROUTER has a default route towards eth1.
dst entries for traffic arriving from eth0 would have DST_NOPOLICY
and would be cached and therefore can be reused by traffic originating
from ipsec0, skipping policy check.
Fix by setting a IPSKB_NOPOLICY flag in IPCB and observing it instead
of the DST in IN/FWD IPv4 policy checks.

We currently track whether we're associated and which the
BSS is in the same variable (ifmgd->associated), but for
MLD we'll need to move the BSS pointer to be per link,
while the question whether we're associated or not is for
the whole interface.
Add ifmgd->assoc_bss that stores the pointer and change
ifmgd->associated to be just a bool, so the question of
whether we're associated can continue working after MLD
rework, without requiring changes, while the BSS pointer
will have to be changed/used checked per link.

Here is one fix, and 3 documentation updates for 5.18-rc7.
The fix is for the firmware loader which resolves a long-reported
problem where the credentials of the firmware loader could be set to a
userspace process without enough permissions to actually load the
firmware image. Many Android vendors have been reporting this for quite
some time.
The documentation updates are for the embargoed-hardware-issues.rst file
to add a new entry, change an existing one, and sort the list to make
changes easier in the future.
All of these have been in linux-next for a while with no reported

outside hard interrupt context. That's overbroad as the requirement
for invoking these handlers in hard interrupt context is only required
for certain interrupt types. The subsequently called code already
contains a warning which triggers conditionally for interrupt chips
which indicate this requirement in their properties.
Remove the overbroad one"

genirq: Remove WARN_ON_ONCE() in generic_handle_domain_irq()
Now when Intel Elkhart Lake uses again common bit timing and there are
no other users for custom bit timing, we can bring back the changes
done by the commit 0ddd83fbeb ("can: m_can: remove support for
custom bit timing").
This effectively reverts commit ea768b2ffe ("Revert "can: m_can:
remove support for custom bit timing"") while taking into account
commit ea22ba40de ("can: m_can: make custom bittiming fields const")
and commit 7d4a101c0b ("can: dev: add sanity check in
can_set_static_ctrlmode()").

Above commit does everything correctly according to the datasheet.
However datasheet wasn't correct.
I got confirmation from hardware engineers that the actual CAN
hardware on Intel Elkhart Lake is based on M_CAN version v3.2.0.
Datasheet was mirroring values from an another specification which was
based on earlier M_CAN version leading to wrong bit timings.
Therefore revert the commit and switch back to common bit timings.

In gem_rx_refill rx_prepared_head is incremented at the beginning of
the while loop preparing the skb and data buffers. If the skb or data
buffer allocation fails, this BD will be unusable BDs until the head
loops back to the same BD (and obviously buffer allocation succeeds).
In the unlikely event that there's a string of allocation failures,
there will be an equal number of unusable BDs and an inconsistent RX
BD chain. Hence increment the head at the end of the while loop to be
clean.

gfs2: Fix filesystem block deallocation for short writes
We're having unresolved issues with the glock holder auto-demotion mechanism
introduced in commit dc732906c2. This mechanism was assumed to be essential
for avoiding frequent short reads and writes until commit 296abc0d91
("gfs2: No short reads or writes upon glock contention"). Since then,
when the inode glock is lost, it is simply re-acquired and the operation
is resumed. This means that apart from the performance penalty, we
might as well drop the inode glock before faulting in pages, and
re-acquire it afterwards.

In gfs2_file_buffered_write, to increase the likelihood that all the
user memory we're trying to write will be resident in memory, carry out
the write in chunks and fault in each chunk of user memory before trying
to write it. Otherwise, some workloads will trigger frequent short
"internal" writes, causing filesystem blocks to be allocated and then
partially deallocated again when writing into holes, which is wasteful
and breaks reservations.
Neither the chunked writes nor any of the short "internal" writes are
user visible.

Instead of counting the number of bytes read from the filesystem,
functions gfs2_file_direct_read and gfs2_file_read_iter count the number
of bytes written into the user buffer. Conversely, functions
gfs2_file_direct_write and gfs2_file_buffered_write count the number of
bytes read from the user buffer. This is nothing but confusing, so
change the read functions to count how many bytes they have read, and
the write functions to count how many bytes they have written.

When a write cannot be carried out in full, gfs2_iomap_end() releases
blocks that have been allocated for this write but haven't been used.
To compute the end of the allocation, gfs2_iomap_end() incorrectly
rounded the end of the attempted write down to the next block boundary
to arrive at the end of the allocation. It would have to round up, but
the end of the allocation is also available as iomap->offset +
iomap->length, so just use that instead.
In addition, use round_up() for computing the start of the unused range.

Merge tag 'nfs-for-5.18-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client bugfixes from Trond Myklebust:
"One more pull request. There was a bug in the fix to ensure that gss-
proxy continues to work correctly after we fixed the AF_LOCAL socket
leak in the RPC code. This therefore reverts that broken patch, and
replaces it with one that works correctly.
Stable fixes:
- SUNRPC: Ensure that the gssproxy client can start in a connected
state
Bugfixes:
- Revert "SUNRPC: Ensure gss-proxy connects on setup"
- nfs: fix broken handling of the softreval mount option"
