9957b38b5e tcp_cubic: make hystart_ack_delay() aware of BIG TCP
hystart_ack_delay() had the assumption that a TSO packet
would not be bigger than GSO_MAX_SIZE.

This will no longer be true.

We should use sk->sk_gso_max_size instead.

This reduces chances of spurious Hystart ACK train detections.

34b92e8d19 net: limit GSO_MAX_SIZE to 524280 bytes
Make sure we will not overflow shinfo->gso_segs

Minimal TCP MSS size is 8 bytes, and shinfo->gso_segs
is a 16bit field.

TCP_MIN_GSO_SIZE is currently defined in include/net/tcp.h,
it seems cleaner to not bring tcp details into include/linux/netdevice.h

7c4e983c4f net: allow gso_max_size to exceed 65536
The code for gso_max_size was added originally to allow for debugging and
workaround of buggy devices that couldn't support TSO with blocks 64K in
size. The original reason for limiting it to 64K was because that was the
existing limits of IPv4 and non-jumbogram IPv6 length fields.

With the addition of Big TCP we can remove this limit and allow the value
to potentially go up to UINT_MAX and instead be limited by the tso_max_size
value.

So in order to support this we need to go through and clean up the
remaining users of the gso_max_size value so that the values will cap at
64K for non-TCPv6 flows. In addition we can clean up the GSO_MAX_SIZE value
so that 64K becomes GSO_LEGACY_MAX_SIZE and UINT_MAX will now be the upper
limit for GSO_MAX_SIZE.

v6: (edumazet) fixed a compile error if CONFIG_IPV6=n,
               in a new sk_trim_gso_size() helper.
               netif_set_tso_max_size() caps the requested TSO size
               with GSO_MAX_SIZE.

5cf15ce3c8 Merge branch 'Renesas-RSZ-V2M-support'
Phil Edworthy says:

====================
Add Renesas RZ/V2M Ethernet support

The RZ/V2M Ethernet is very similar to R-Car Gen3 Ethernet-AVB, though
some small parts are the same as R-Car Gen2.
Other differences are:
* It has separate data (DI), error (Line 1) and management (Line 2) irqs
  rather than one irq for all three.
* Instead of using the High-speed peripheral bus clock for gPTP, it has
  a separate gPTP reference clock.

v4:
 * Add clk_disable_unprepare() for gptp ref clk

v3:
 * Really renamed irq_en_dis_regs to irq_en_dis this time
 * Modified ravb_ptp_extts() to use irq_en_dis
 * Added Reviewed-by tags

v2:
 * Just net patches in this series
 * Instead of reusing ch22 and ch24 interrupt names, use the proper names
 * Renamed irq_en_dis_regs to irq_en_dis
 * Squashed use of GIC reg versus GIE/GID and got rid of separate gptp_ptm_gic feature.
 * Move err_mgmt_irqs code under multi_irqs
 * Minor editing of the commit msgs

cb99badde1 ravb: Separate handling of irq enable/disable regs into feature
Currently, when the HW has a single interrupt, the driver uses the
GIC, TIC, RIC0 registers to enable and disable interrupts.
When the HW has multiple interrupts, it uses the GIE, GID, TIE, TID,
RIE0, RID0 registers.

However, other devices, e.g. RZ/V2M, have multiple irqs and only have
the GIC, TIC, RIC0 registers.
Therefore, split this into a separate feature.

a7931ac161 dt-bindings: net: renesas,etheravb: Document RZ/V2M SoC
Document the Ethernet AVB IP found on RZ/V2M SoC.
It includes the Ethernet controller (E-MAC) and Dedicated Direct memory
access controller (DMAC) for transferring transmitted Ethernet frames
to and received Ethernet frames from respective storage areas in the
RAM at high speed.
The AVB-DMAC is compliant with IEEE 802.1BA, IEEE 802.1AS timing and
synchronization protocol, IEEE 802.1Qav real-time transfer, and the
IEEE 802.1Qat stream reservation protocol.

R-Car has a pair of combined interrupt lines:
 ch22 = Line0_DiA | Line1_A | Line2_A
 ch23 = Line0_DiB | Line1_B | Line2_B
Line0 for descriptor interrupts (which we call dia and dib).
Line1 for error related interrupts (which we call err_a and err_b).
Line2 for management and gPTP related interrupts (mgmt_a and mgmt_b).

RZ/V2M hardware has separate interrupt lines for each of these.

It has 3 clocks; the main AXI clock, the AMBA CHI (Coherent Hub
Interface) clock and a gPTP reference clock.

569cf386ec mac80211: minstrel_ht: support ieee80211_rate_status
This patch adds support for the new struct ieee80211_rate_status and its
annotation in struct ieee80211_tx_status in minstrel_ht.

In minstrel_ht_tx_status, a check for the presence of instances of the
new struct in ieee80211_tx_status is added. Based on this, minstrel_ht
then gets and updates internal rate stats with either struct
ieee80211_rate_status or ieee80211_tx_info->status.rates.
Adjusted variants of minstrel_ht_txstat_valid, minstrel_ht_get_stats,
minstrel_{ht/vht}_get_group_idx are added which use struct
ieee80211_rate_status and struct rate_info instead of the legacy structs.

struct rate_info from cfg80211.h does not provide whether short preamble
was used for the transmission. So we retrieve this information from VIF
and STA configuration and cache it in a new flag in struct minstrel_ht_sta
per rate control instance.

44fa75f207 mac80211: extend current rate control tx status API
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.

e6175a2ed1 xfrm: fix "disable_policy" flag use when arriving from different devices
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.

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.

97f7a47024 mac80211: unify CCMP/GCMP AAD construction
Ping-Ke's previous patch adjusted the CCMP AAD construction
to properly take the order bit into account, but failed to
update the (identical) GCMP AAD construction as well.

Unify the AAD construction between the two cases.

0cdd776ec9 Driver core fixes for 5.18-rc7
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
 issues.

d6da788102 can: m_can: remove support for custom bit timing, take #2
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()").

This reverts commit 0e8ffdf3b8.

Commit 0e8ffdf3b8 ("can: m_can: pci: use custom bit timings for
Elkhart Lake") broke the test case using bitrate switching.

| ip link set can0 up type can bitrate 500000 dbitrate 4000000 fd on
| ip link set can1 up type can bitrate 500000 dbitrate 4000000 fd on

|     -D 11223344deadbeef55667788feedf00daabbccdd44332211 -n 1 -v -v

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.

Fixes: ea4c178768 ("can: m_can: pci: use custom bit timings for Elkhart Lake")

9500acc631 net: macb: Increment rx bd head after allocating skb and buffer
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.

d971308815 ice: Expose RSS indirection tables for queue groups via ethtool
When ADQ queue groups (TCs) are created via tc mqprio command,
RSS contexts and associated RSS indirection tables are configured
automatically per TC based on the queue ranges specified for
each traffic class.

For ex:
tc qdisc add dev enp175s0f0 root mqprio num_tc 3 map 0 1 2 \
	queues 2@0 8@2 4@10 hw 1 mode channel

will create 3 queue groups (TC 0-2) with queue ranges 2, 8 and 4
in 3 queue groups. Each queue group is associated with its
own RSS context and RSS indirection table.

Add support to expose RSS indirection tables for all ADQ queue
groups using ethtool RSS contexts interface.
	ethtool -x enp175s0f0 context <tc-num>

Mat Martineau says:

====================
mptcp: Subflow accounting fix

This series contains a bug fix affecting the in-kernel path manager
(patch 1), where closing subflows would sometimes not adjust the PM's
count of active subflows. Patch 2 updates the selftests to exercise the
new code.

95d6865178 mptcp: fix subflow accounting on close
If the PM closes a fully established MPJ subflow or the subflow
creation errors out in it's early stage the subflows counter is
not bumped accordingly.

This change adds the missing accounting, additionally taking care
of updating accordingly the 'accept_subflow' flag.

Pull more drm fixes from Dave Airlie:
 "Turns out I was right, some fixes hadn't made it to me yet. The vmwgfx
  ones also popped up later, but all seem like bad enough things to fix.
  The dma-buf, vc4 and nouveau ones are all pretty small.

  The fbdev fixes are a bit more complicated: a fix to cleanup fbdev
  devices properly, uncovered some use-after-free bugs in existing
  drivers. Then the fix for those bugs wasn't correct. This reverts that
  fix, and puts the proper fixes in place in the drivers to avoid the
  use-after-frees.

  This has had a fair number of eyes on it at this stage, and I'm
  confident enough that it puts things in the right place, and is less
  dangerous than reverting our way out of the initial change at this
  stage.

725f22a147 block/mq-deadline: Set the fifo_time member also if inserting at head
Before commit 322cff70d4 the fifo_time member of requests on a dispatch
list was not used. Commit 322cff70d4 introduces code that reads the
fifo_time member of requests on dispatch lists. Hence this patch that sets
the fifo_time member when adding a request to a dispatch list.
