[ Upstream commit 372539def2824c43b6afe2403045b140f65c5acc ]
Max MTU sent to VF is set to 0 during memory allocation. It cause
that max MTU on VF is changed to IAVF_MAX_RXBUFFER and does not
depend on data from HW.
Set max_mtu field in virtchnl_vf_resource struct to inform
VF in GET_VF_RESOURCES msg what size should be max frame.

After setting port VLAN and MTU to 9000 on VF with ice driver there
was an iavf error
"PF returned error -5 (IAVF_ERR_PARAM) to our request 6".
During queue configuration, VF's max packet size was set to
IAVF_MAX_RXBUFFER but on ice max frame size was smaller by VLAN_HLEN
due to making some space for port VLAN as VF is not aware whether it's
in a port VLAN. This mismatch in sizes caused ice to reject queue
configuration with ERR_PARAM error. Proper max_mtu is sent from ice PF
to VF with GET_VF_RESOURCES msg but VF does not look at this.
In iavf change max_frame from IAVF_MAX_RXBUFFER to max_mtu
received from pf with GET_VF_RESOURCES msg to make vf's
max_frame_size dependent from pf. Add check if received max_mtu is
not in eligible range then set it to IAVF_MAX_RXBUFFER.

commit 0060c8783330 ("net: stmmac: implement support for passive mode
converters via dt") has changed the plat->interface field semantics from
containing the PHY-mode to specifying the MAC-PCS interface mode. Due to
that the loongson32 platform code will leave the phylink interface
uninitialized with the PHY-mode intended by the means of the actual
platform setup. The commit-author most likely has just missed the
arch-specific code to fix. Let's mend the Loongson32 platform code then by
assigning the PHY-mode to the phy_interface field of the STMMAC platform

Netdev drivers are expected to call dev_{uc,mc}_sync() in their
ndo_set_rx_mode method and dev_{uc,mc}_unsync() in their ndo_stop method.
This is mentioned in the kerneldoc for those dev_* functions.
The team driver calls dev_{uc,mc}_unsync() during ndo_uninit instead of
ndo_stop. This is ineffective because address lists (dev->{uc,mc}) have
already been emptied in unregister_netdevice_many() before ndo_uninit is
called. This mistake can result in addresses being leftover on former team
ports after a team device has been deleted; see test_LAG_cleanup() in the
last patch in this series.
Add unsync calls at their expected location, team_close().
v3:
* When adding or deleting a port, only sync/unsync addresses if the team
device is up. In other cases, it is taken care of at the right time by
ndo_open/ndo_set_rx_mode/ndo_stop.

The root cause is:
1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW
and skb->protocol is not specified as in packet_parse_headers()
2. packet_direct_xmit() doesn't reset skb->mac_header as dev_queue_xmit()
In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is
called. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which
use "skb->head + skb->mac_header", out-of-bound access occurs.
This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2()
and reset mac header in multicast to solve this out-of-bound bug.

ct_sip_next_header and ct_sip_get_header return an absolute
value of matchoff, not a shift from current dataoff.
So dataoff should be assigned matchoff, not incremented by it.
This issue can be seen in the scenario when there are multiple
Contact headers and the first one is using a hostname and other headers
use IP addresses. In this case, ct_sip_walk_headers will work as follows:
The first ct_sip_get_header call to will find the first Contact header
but will return -1 as the header uses a hostname. But matchoff will
be changed to the offset of this header. After that, dataoff should be
set to matchoff, so that the next ct_sip_get_header call find the next
Contact header. But instead of assigning dataoff to matchoff, it is
incremented by it, which is not correct, as matchoff is an absolute
value of the offset. So on the next call to the ct_sip_get_header,
dataoff will be incorrect, and the next Contact header may not be
found at all.

We've found the AUX channel to be less reliable with PCLK_EDP at a

with PSR-enabled panels (like Gru-Kevin), since we make heavy, constant

According to Rockchip, using any rate other than 24 MHz can cause
"problems between syncing the PHY an PCLK", which leads to all sorts of
unreliabilities around register operations.

The Gru-Bob board does not have a pull-up resistor on its

specified the pin configuration correctly as a pull-up, but this didn't
get ported correctly to upstream.
This means Bob's WLAN_HOST_WAKE# pin is floating, causing inconsistent
wakeup behavior.
Note that bt_host_wake_l has a similar dynamic, but apparently the
upstream choice was to redundantly configure both internal and external
pull-up on Kevin (see the "Kevin has an external pull up" comment in
rk3399-gru.dtsi). This doesn't cause any functional problem, although
it's perhaps wasteful.

commit 5f56a74cc0a6d9b9f8ba89cea29cd7c4774cb2b1 upstream.
We currently check the MokSBState variable to decide whether we should
treat UEFI secure boot as being disabled, even if the firmware thinks
otherwise. This is used by shim to indicate that it is not checking
signatures on boot images. In the kernel, we use this to relax lockdown
policies.
However, in cases where shim is not even being used, we don't want this
variable to interfere with lockdown, given that the variable may be
non-volatile and therefore persist across a reboot. This means setting
it once will persistently disable lockdown checks on a given system.
So switch to the mirrored version of this variable, called MokSBStateRT,
which is supposed to be volatile, and this is something we can check.

[ Upstream commit 692a8ebcfc24f4a5bea0eb2967e450f584193da6 ]
Whenever the atmel_rs485_config() driver method would be called,
the USART mode is reset to normal mode before even checking if
RS485 flag is set, thus resulting in losing the previous USART
mode in the case where the checking fails.
Some tools, such as `linux-serial-test`, lead to the driver calling
this method when doing the setup of the serial port: after setting the
port mode (Hardware Flow Control, Normal Mode, RS485 Mode, etc.),
`linux-serial-test` tries to enable/disable RS485 depending on
the commandline arguments that were passed.
Example of how this issue could reveal itself:
When doing a serial communication with Hardware Flow Control through
`linux-serial-test`, the tool would lead to the driver roughly doing
the following:
- set the corresponding bit to 1 (ATMEL_US_USMODE_HWHS bit in the
ATMEL_US_MR register) through the atmel_set_termios() to enable
Hardware Flow Control
- disable RS485 through the atmel_config_rs485() method
Thus, when the latter is called, the mode will be reset and the
previously set bit is unset, leaving USART in normal mode instead of
the expected Hardware Flow Control mode.
This fix ensures that this reset is only done if the checking for
RS485 succeeds and that the previous mode is preserved otherwise.

At this moment, TXEMPTY is checked before sending data on RS485 and ISO7816
modes. However, TXEMPTY is risen when FIFO (if used) or the Transmit Shift
Register are empty, even though TXRDY might be up and controller is able to
receive data. Since the controller sends data only when TXEMPTY is ready,
on RS485, when DMA is not used, the RTS pin is driven low after each byte.
With this patch, the characters will be transmitted when TXRDY is up and
so, RTS pin will remain high between bytes.
The performance improvement on RS485 is about 8% with a baudrate of 300.

ieee80211_scan_rx() tries to access scan_req->flags after a
null check, but a UAF is observed when the scan is completed
and __ieee80211_scan_completed() executes, which then calls
cfg80211_scan_done() leading to the freeing of scan_req.
Since scan_req is rcu_dereference()'d, prevent the racing in
__ieee80211_scan_completed() by ensuring that from mac80211's
POV it is no longer accessed from an RCU read critical section
before we call cfg80211_scan_done().

[ Upstream commit 548011957d1d72e0b662300c8b32b81d593b796e ]
Currently xhci-mtk needs software-managed bandwidth allocation for
periodic endpoints, it allocates the microframe index for the first
start-split packet for each endpoint. As this index allocation logic
should avoid the conflicts with other full/low-speed periodic endpoints,
it uses the worst case byte budgets on high-speed bus bandwidth
For example, for an isochronos IN endpoint with 192 bytes budget,
it will consume the whole 4 u-frames(188 * 4) while the actual
full-speed bus budget should be just 192bytes.
This patch changes the low/full-speed bandwidth allocation logic
to use "approximate" best case budget for lower speed bandwidth
management. For the same endpoint from the above example, the
approximate best case budget is now reduced to (188 * 2) bytes.
Without this patch, many usb audio headsets with 3 interfaces
(audio input, audio output, and HID) cannot be configured
on xhci-mtk.

In USB2 Spec:
"11.18.5 TT Response Generation
In general, there will be two (or more) complete-split
transactions scheduled for a periodic endpoint.
However, for interrupt endpoints, the maximum size of
the full-/low-speed transaction guarantees that it can
never require more than two complete-split transactions.
Two complete-split transactions are only required
when the transaction spans a microframe boundary."
Due to the maxp is 64, and less then 188 (at most in one
microframe), seems never span boundary, so use only one CS
for FS/LS interrupt transfer, this will save some bandwidth.

Relocate the pullups_connected check until after it is ensured that there
are no runtime PM transitions. If another context triggered the DWC3
core's runtime resume, it may have already enabled the Run/Stop. Do not
re-run the entire pullup sequence again, as it may issue a core soft
reset while Run/Stop is already set.

If the GEVNTCOUNT indicates events in the event buffer, the driver needs
to acknowledge them before the controller can halt. Simply let the
interrupt handler acknowledges the remaining event generated by the
controller while polling for DSTS.DEVCTLHLT. This avoids disabling irq
and taking care of race condition between the interrupt handlers and
pullup().

Don't do soft-disconnect if it's previously done. Likewise, don't do
soft-connect if the device is currently connected and running. It would
break normal operation.
Currently the caller of pullup() (udc's sysfs soft_connect) only checks
if it had initiated disconnect to prevent repeating soft-disconnect. It
doesn't check for soft-connect. To be safe, let's keep the check here
regardless whether the udc core is fixed.

There is a race present where the DWC3 runtime resume runs in parallel
to the UDC unbind sequence. This will eventually lead to a possible
scenario where we are enabling the run/stop bit, without a valid
composition defined.
Thread#1 (handling UDC unbind):
usb_gadget_remove_driver()
-->usb_gadget_disconnect()
-->dwc3_gadget_pullup(0)
--> continue UDC unbind sequence
-->Thread#2 is running in parallel here
Thread#2 (handing next cable connect)
__dwc3_set_mode()
-->pm_runtime_get_sync()
-->dwc3_gadget_resume()
-->dwc->gadget_driver is NOT NULL yet
-->dwc3_gadget_run_stop(1)
--> _dwc3gadget_start()
...
Fix this by tracking the pullup disable routine, and avoiding resuming
of the DWC3 gadget. Once the UDC is re-binded, that will trigger the
pullup enable routine, which would handle enabling the DWC3 gadget.
