PPDU TxS can only report MPDU count whereas mac80211 requires MSDU scale
(NL80211_STA_INFO_TX_PACKETS), so switch to get MSDU counts from WA
statistic.
Note that mt7915 WA firmware only counts tx_packet for WED path, so driver
needs to take care of host path additionally.

The Group ID Management frame is an Action frame of category VHT.
It is transmitted by the AP to assign or change the user position
of a STA for one or more group IDs.
Also, sniffer can use a given group id to monitor STA that belongs
to that group.

When header translation failure is indicated, the hardware will insert
an extra 2-byte field containing the data length after the protocol
type field. This happens either when the LLC-SNAP pattern did not match,
or if a VLAN header was detected.

mt7921_usb_sdio_tx_prepare_skb() calls mt7921_usb_sdio_write_txwi() and
mt7921_skb_add_usb_sdio_hdr(), both of which blindly assume that
adequate headroom will be available in the passed skb. This assumption
typically is satisfied when the skb was allocated in the net core for
transmission via the mt7921 netdev (although even that is only an
optimization and is not strictly guaranteed), but the assumption is
sometimes not satisfied when the skb originated in the receive path of
another netdev and was passed through to the mt7921, such as by the
bridge layer. Blindly prepending bytes to an skb is always wrong.
This commit introduces a call to skb_cow_head() before the call to
mt7921_usb_sdio_write_txwi() in mt7921_usb_sdio_tx_prepare_skb() to
ensure that at least MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE bytes can be
pushed onto the skb.
Without this fix, I can trivially cause kernel panics by bridging an
MT7921AU-based USB 802.11ax interface with an Ethernet interface on an
Intel Atom-based x86 system using its onboard RTL8169 PCI Ethernet
adapter and also on an ARM-based Raspberry Pi 1 using its onboard
SMSC9512 USB Ethernet adapter. Note that the panics do not occur in
every system configuration, as they occur only if the receiving netdev
leaves less headroom in its received skbs than the mt7921 needs for its
SDIO headers.
Here is an example stack trace of this panic on Raspberry Pi OS Lite
2023-02-21 running kernel 6.1.24+ [1]:
skb_panic from skb_push+0x44/0x48
skb_push from mt7921_usb_sdio_tx_prepare_skb+0xd4/0x190 [mt7921_common]

After this fix, bridging the mt7921 interface works fine on both of my
previously problematic systems.

During FIFO/DMA modes dynamic switching, only corresponding interrupts are
enabled. However its possible that FIFO related interrupt status registers
get set during DMA mode. For example WR_FIFO_EMPTY bit is set during DMA

When using the cleaner policy to decommission the cache, there is
never any writeback started from the cache as it is constantly delayed
due to normal I/O keeping the device busy. Meaning @idle=false was
always being passed to clean_target_met()
Fix this by adding a specific 'cleaner' flag that is set when the
cleaner policy is configured. This flag serves to always allow the
cleaner's writeback work to be queued until the cache is
decommissioned (even if the cache isn't idle).

tegra_xudc_powerdomain_init()"
This reverts commit f08aa7c80dac27ee00fa6827f447597d2fba5465.
The reverted commit was based on static analysis and a misunderstanding
of how PTR_ERR() and NULLs are supposed to work. When a function
returns both pointer errors and NULL then normally the NULL means
"continue operating without a feature because it was deliberately
turned off". The NULL should not be treated as a failure. If a driver
cannot work when that feature is disabled then the KConfig should
enforce that the function cannot return NULL. We should not need to
test for it.
In this driver, the bug means that probe cannot succeed when CONFIG_PM
is disabled.

This reverts commit b138e23d3dff90c0494925b4c1874227b81bddf7.
AutoRetry has been found to sometimes cause controller freezes when
communicating with buggy USB devices.
This controller feature allows the controller in host mode to send
non-terminating/burst retry ACKs instead of terminating retry ACKs
to devices when a transaction error (CRC error or overflow) occurs.
Unfortunately, if the USB device continues to respond with a CRC error,
the controller will not complete endpoint-related commands while it
keeps trying to auto-retry. [3] The xHCI driver will notice this once
it tries to abort the transfer using a Stop Endpoint command and
does not receive a completion in time. [1]
This situation is reported to dmesg:
[sda] tag#29 uas_eh_abort_handler 0 uas-tag 1 inflight: CMD IN
[sda] tag#29 CDB: opcode=0x28 28 00 00 69 42 80 00 00 48 00
xhci-hcd: xHCI host not responding to stop endpoint command
xhci-hcd: xHCI host controller not responding, assume dead
xhci-hcd: HC died; cleaning up
Some users observed this problem on an Odroid HC2 with the JMS578
USB3-to-SATA bridge. The issue can be triggered by starting
a read-heavy workload on an attached SSD. After a while, the host
controller would die and the SSD would disappear from the system. [1]
Further analysis by Synopsys determined that controller revisions
other than the one in Odroid HC2 are also affected by this.
The recommended solution was to disable AutoRetry altogether.
This change does not have a noticeable performance impact. [2]
Revert the enablement commit. This will keep the AutoRetry bit in
the default state configured during SoC design [2].

The hardware in question is an external PCIe card. It looks to me like the quirk
needs to be narrowed down. But this needs information about the hardware showing
the issue this quirk is to fix. So for now a clean revert.

The Focusrite Scarlett audio device does not behave correctly during
resumes. Below is what happens during every resume (captured with
Beagle 5000):
<Suspend>
<Resume>
<Reset>/<Chirp J>/<Tiny J>
<Reset/Target disconnected>
<High Speed>
The Scarlett disconnects and is enumerated again.
However from time to time it drops completely off the USB bus during
resume. Below is captured occurrence of such an event:
<Suspend>
<Resume>
<Reset>/<Chirp J>/<Tiny J>
<Reset>/<Chirp K>/<Tiny K>
<High Speed>
<Corrupted packet>
<Reset/Target disconnected>
To fix the condition a user has to unplug and plug the device again.
With USB_QUIRK_RESET_RESUME applied ("usbcore.quirks=1235:8211:b")
for the Scarlett audio device the issue still reproduces.
Applying USB_QUIRK_DISCONNECT_SUSPEND ("usbcore.quirks=1235:8211:m")
fixed the issue and the Scarlett audio device didn't drop off the USB
bus for ~5000 suspend/resume cycles where originally issue reproduced in
~100 or less suspend/resume cycles.

Commit c4a5153e87fd ("usb: dwc3: core: Power-off core/PHYs on
system_suspend in host mode") replaces check for HOST only dr_mode with
current_dr_role. But during booting, the current_dr_role isn't
initialized, thus the device side reset is always issued even if dwc3
was configured as host-only. What's more, on some platforms with host
only dwc3, aways issuing device side reset by accessing device register
block can cause kernel panic.

The ohci_hcd_at91_drv_suspend() sets ohci->rh_state to OHCI_RH_HALTED when
suspend which will let the ohci_irq() skip the interrupt after resume. And
nobody to handle this interrupt.
According to the comment in ohci_hcd_at91_drv_suspend(), it need to reset
when resume from suspend(MEM) to fix by setting "hibernated" argument of
ohci_resume().

Allow moving the wiphy device for mwififex to a non-inital network
namespace. Many wireless drivers enable this flag implicitly by
initializing through the generic ieee80211_alloc_hw_nm function. As
mwifiex does not utilize this function WIPHY_FLAG_NETNS_OK must be set
explicitly.
Moving to network namespace and working connection tested using
wpa_supplicant from a network namespace as well as from a container on
GyroidOS. The hardware was the Toradex Apalis i.MX8QM Board using the
Azurewave AW-CM276NF wireless module.

When compiling with gcc 13.1 and CONFIG_FORTIFY_SOURCE=y,
I've noticed the following:
In function ‘fortify_memcpy_chk’,
inlined from ‘mwifiex_construct_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:765:3,
inlined from ‘mwifiex_send_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:856:6:
./include/linux/fortify-string.h:529:25: warning: call to ‘__read_overflow2_field’
declared with attribute warning: detected read beyond size of field (2nd parameter);
maybe use struct_group()? [-Wattribute-warning]
529 | __read_overflow2_field(q_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The compiler actually complains on:
memmove(pos + ETH_ALEN, &mgmt->u.action.category,
sizeof(mgmt->u.action.u.tdls_discover_resp));
and it happens because the fortification logic interprets this
as an attempt to overread 1-byte 'u.action.category' member of
'struct ieee80211_mgmt'. To silence this warning, it's enough
to pass an address of 'u.action' itself instead of an address
of its first member.
This also fixes an improper usage of 'sizeof()'. Since 'skb' is
extended with 'sizeof(mgmt->u.action.u.tdls_discover_resp) + 1'
bytes (where 1 is actually 'sizeof(mgmt->u.action.category)'),
I assume that the same number of bytes should be copied.

USB-serial device ids for 6.5-rc4
Here are some new modem device ids and a new "simple" driver for a CAN
bus device.
Included is also a patch sorting the "simple" driver entries in order to
make it more obvious where new ones should be added.
All have been in linux-next with no reported issues.
* tag 'usb-serial-6.5-rc4' of https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial:
USB: serial: simple: sort driver entries
