The implementation assumed that the client always wants the whole 16
byte AES-GCM tag. Now we respect the requested authentication tag size
fetched using crypto_aead_authsize().

The driver was optimized to only do cache maintenance for the last
word of the dma descriptor status array. Unfortunately an omission
also passed the last word as the address of the array start to the DMA
engine. In most cases this goes unnoticed since the hardware aligns
the address to a 64 byte boundary.

Clients may submit a new requests from the completion callback
context. The driver was not prepared to receive a request in this
state because it already held the request queue lock and a recursive
lock error is triggered.
Now all completions are queued up until we are ready to drop the queue
lock and then delivered.
The fault was triggered by TCP over an IPsec connection in the LTP
test suite:
LTP: starting tcp4_ipsec02 (tcp_ipsec.sh -p ah -m transport -s "100 1000 65535")

This patch fixes the incorrect external id that kernel reports to user mode
driver. Raven2's rev_id is starts from 0x8, so its external id (0x81) should
start from rev_id + 0x79 (0x81 - 0x8). And Raven's rev_id should be 0x21 while
rev_id == 1.

Revert commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal").
That commit breaks boot on Macchiatobin board when a Mellanox NIC is
present in the PCIe slot.
It turns out that full reset cycle requires first comphy serdes
initialization. Reset signal toggle without comphy initialization makes
access to PCI configuration registers stall indefinitely. U-Boot toggles
the Macchiatobin PCIe reset line already at boot, after initializing the
comphy serdes.
So while commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal") enables PCIe on platforms that U-Boot does not touch the
reset line (like Clearfog GT-8K), it breaks PCIe (and boot) on the
Macchiatobin board.
Revert commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal") entirely to fix the Macchiatobin regression.

WoL handling for the RTL8168 family is a little bit tricky because of
different types of broken BIOS and/or chip quirks.
Two known issues:
1. Network properly resumes from suspend only if WoL is enabled in the chip.
2. Some notebooks wake up immediately if system is suspended and network
device is wakeup-enabled.
Few patches tried to deal with this:
7edf6d314cd0 ("r8169: disable WOL per default")
18041b523692 ("r8169: restore previous behavior to accept BIOS WoL
settings")
Currently we have the situation that the chip WoL settings as set by
the BIOS are respected (to prevent issue 1), but the device doesn't get
wakeup-enabled (to prevent issue 2).
This leads to another issue:
If systemd is told to set WoL it first checks whether the requested
settings are active already (and does nothing if yes). Due to the chip
WoL flags being set properly systemd assumes that WoL is configured
properly in our case. Result is that device doesn't get wakeup-enabled
and WoL doesn't work (until it's set e.g. by ethtool).
This patch now:
- leaves the chip WoL settings as is (to prevent issue 1)
- keeps the behavior to not wakeup-enable the device initially
(to prevent issue 2)
- In addition we report WoL as being disabled in get_wol, matching
that device isn't wakeup-enabled. If systemd is told to enable WoL,
it will therefore detect that it has to do something and will
call set_wol.
Of course the user still has the option to override this with
e.g. ethtool.
v2:
- Don't just exclude __rtl8169_get_wol() from compiling, remove it.
v3:
- adjust commit message

There still is a race window after the commit b027e2298bd588
("tty: fix data race between tty_init_dev and flush of buf"),
and we encountered this crash issue if receive_buf call comes
before tty initialization completes in tty_open and
tty->driver_data may be NULL.
CPU0 CPU1

n_tty_receive_buf_common
__receive_buf
uart_flush_chars
uart_start
/*tty->driver_data is NULL*/
tty->ops->open
/*init tty->driver_data*/
it can be fixed by extending ldisc semaphore lock in tty_init_dev
to driver_data initialized completely after tty->ops->open(), but
this will lead to get lock on one function and unlock in some other
function, and hard to maintain, so fix this race only by checking
tty->driver_data when receiving, and return if tty->driver_data
is NULL, and n_tty_receive_buf_common maybe calls uart_unthrottle,
so add the same check.
Because the tty layer knows nothing about the driver associated with the
device, the tty layer can not do anything here, it is up to the tty
driver itself to check for this type of race. Fix up the serial driver
to correctly check to see if it is finished binding with the device when
being called, and if not, abort the tty calls.

There's an issue with how sense requests are handled in IDE. If ide-cd
encounters an error, it queues a sense request. With how IDE request
handling is done, this is the next request we need to handle. But it's
impossible to guarantee this, as another request could come in between
the sense being queued, and ->queue_rq() being run and handling it. If
that request ALSO fails, then we attempt to doubly queue the single
sense request we have.
Since we only support one active request at the time, defer request
processing when a sense request is queued.

an invalid value. For instance, supposed that the previous voltage is
5V, and the new voltage range in the APDO is 7V-12V. Then the output
voltage in the RDO should not be set to 5V which is lower than the
possible min_volt 7V.
Fix this by choosing the maximal value between the previous voltage and
the new min_volt first. And ensure that this value will not exceed the
new max_volt. The new out_volt will fall within the new voltage range
while being the closest value compared to the previous out_volt.

usb: fixes for v5.0-rc4
Dwc3 got a fix for cases when gadget driver queue an OUT request of
length 0; this is a case that has been overlooked for quite some time
now.
Exynos' dwc3 glue layer got a fix on the error path for those cases
where clk_prepare_enable() fails.
TI's AM335x PHY driver got a fix for a race condition during
probe. This race happened because driver was powering off the PHY only
after adding the PHY handle to the framework. The result is that we
could fall into a situation where user of the PHY (MUSB) could call
phy_init() before phy driver's probe() called phy_poweroff() which
would result in a powered off PHY after phy_init() was called.
The old net2272 driver got a fix for an erroneous use of bitwise
negation.

In stmmac xmit callback we use a different flow for TSO packets but TSO
xmit callback is not disabling the EEE mode.
Fix this by disabling earlier the EEE mode, i.e. before calling the TSO
xmit callback.

The number of TSO enabled channels in HW can be different than the
number of total channels. There is no way to determined, at runtime, the
number of TSO capable channels and its safe to assume that if TSO is
enabled then at least channel 0 will be TSO capable.
Lets always send TSO packets from Queue 0.

If we don't have DT then stmmac_clk will not be available. Let's add a
new Platform Data field so that we can specify the refclk by this mean.
This way we can still use the coalesce command in PCI based setups.

While implementing ipvlan l3 and l3s mode for kubernetes CNI plugin,
I ran into the issue that while l3 mode is working fine, l3s mode
does not have any connectivity to kube-apiserver and hence all pods
end up in Error state as well. The ipvlan master device sits on
top of a bond device and hostns traffic to kube-apiserver (also running
in hostns) is DNATed from 10.152.183.1:443 to 139.178.29.207:37573
where the latter is the address of the bond0. While in l3 mode, a
curl to https://10.152.183.1:443 or to https://139.178.29.207:37573
works fine from hostns, neither of them do in case of l3s. In the
latter only a curl to https://127.0.0.1:37573 appeared to work where
for local addresses of bond0 I saw kernel suddenly starting to emit
ARP requests to query HW address of bond0 which remained unanswered
and neighbor entries in INCOMPLETE state. These ARP requests only
happen while in l3s.
Debugging this further, I found the issue is that l3s mode is piggy-
backing on l3 master device, and in this case local routes are using
l3mdev_master_dev_rcu(dev) instead of net->loopback_dev as per commit
f5a0aab84b74 ("net: ipv4: dst for local input routes should use l3mdev
if relevant") and 5f02ce24c269 ("net: l3mdev: Allow the l3mdev to be
a loopback"). I found that reverting them back into using the
net->loopback_dev fixed ipvlan l3s connectivity and got everything
working for the CNI.
Now judging from 4fbae7d83c98 ("ipvlan: Introduce l3s mode") and the
l3mdev paper in [0] the only sole reason why ipvlan l3s is relying
on l3 master device is to get the l3mdev_ip_rcv() receive hook for
setting the dst entry of the input route without adding its own
ipvlan specific hacks into the receive path, however, any l3 domain
semantics beyond just that are breaking l3s operation. Note that
ipvlan also has the ability to dynamically switch its internal
operation from l3 to l3s for all ports via ipvlan_set_port_mode()
at runtime. In any case, l3 vs l3s soley distinguishes itself by
'de-confusing' netfilter through switching skb->dev to ipvlan slave
device late in NF_INET_LOCAL_IN before handing the skb to L4.
Minimal fix taken here is to add a IFF_L3MDEV_RX_HANDLER flag which,
if set from ipvlan setup, gets us only the wanted l3mdev_l3_rcv() hook
without any additional l3mdev semantics on top. This should also have
minimal impact since dev->priv_flags is already hot in cache. With
this set, l3s mode is working fine and I also get things like
masquerading pod traffic on the ipvlan master properly working.

Call tun_set_real_num_queues() after the increment of tun->numqueues
since the former depends on it. Otherwise, the number of queues is not
correctly accounted for, which results to warnings similar to:
"vnet0 selects TX queue 11, but real number of TX queues is 11".

Some devices are slow and cannot keep up with the SPI bus and therefore
require a short delay between words of the SPI transfer.
The example of this that I'm looking at is a SAMA5D2 with a minimum SPI
clock of 400kHz talking to an AVR-based SPI slave. The AVR cannot put
bytes on the bus fast enough to keep up with the SoC's SPI controller
even at the lowest bus speed.
This patch introduces the ability to specify a required inter-word
delay for SPI devices. It is up to the controller driver to configure
itself accordingly in order to introduce the requested delay.
Note that, for spi_transfer, there is already a field word_delay that
provides similar functionality. This field, however, is specified in
clock cycles (and worse, SPI controller cycles, not SCK cycles); that
makes this value dependent on the master clock instead of the device
clock for which the delay is intended to provide some relief. This
patch leaves this old word_delay in place and provides a time-based
word_delay_us alongside it; the new field fits in the struct padding
so struct size is constant. There is only one in-kernel user of the
word_delay field and presumably that driver could be reworked to use
the time-based value instead.
The time-based delay is limited to 8 bits as these delays are intended
to be short. The SAMA5D2 that I've tested this on limits delays to a
maximum of ~100us, which is already many word-transfer periods even at
the minimum transfer speed supported by the controller.
