'cipher' algorithms (single block ciphers) are always synchronous, so
passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
effect. Many users therefore already don't pass it, but some still do.
This inconsistency can cause confusion, especially since the way the
'mask' argument works is somewhat counterintuitive.
Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.
This patch shouldn't change any actual behavior.

Pull networking updates from David Miller:
1) New ipset extensions for matching on destination MAC addresses, from
Stefano Brivio.
2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to
nfp driver. From Stefano Brivio.
3) Implement GRO for plain UDP sockets, from Paolo Abeni.
4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT
bit so that we could support the entire vlan_tci value.
5) Rework the IPSEC policy lookups to better optimize more usecases,
from Florian Westphal.
6) Infrastructure changes eliminating direct manipulation of SKB lists
wherever possible, and to always use the appropriate SKB list
helpers. This work is still ongoing...
7) Lots of PHY driver and state machine improvements and
simplifications, from Heiner Kallweit.
8) Various TSO deferral refinements, from Eric Dumazet.
9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov.
10) Batch dropping of XDP packets in tuntap, from Jason Wang.
11) Lots of cleanups and improvements to the r8169 driver from Heiner
Kallweit, including support for ->xmit_more. This driver has been
getting some much needed love since he started working on it.
12) Lots of new forwarding selftests from Petr Machata.
13) Enable VXLAN learning in mlxsw driver, from Ido Schimmel.
14) Packed ring support for virtio, from Tiwei Bie.
15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov.
16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu.
17) Implement coalescing on TCP backlog queue, from Eric Dumazet.
18) Implement carrier change in tun driver, from Nicolas Dichtel.
19) Support msg_zerocopy in UDP, from Willem de Bruijn.
20) Significantly improve garbage collection of neighbor objects when
the table has many PERMANENT entries, from David Ahern.
21) Remove egdev usage from nfp and mlx5, and remove the facility
completely from the tree as it no longer has any users. From Oz
Shlomo and others.
22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
therefore abort the operation before the commit phase (which is the
NETDEV_CHANGEADDR event). From Petr Machata.
23) Add indirect call wrappers to avoid retpoline overhead, and use them
in the GRO code paths. From Paolo Abeni.
24) Add support for netlink FDB get operations, from Roopa Prabhu.
25) Support bloom filter in mlxsw driver, from Nir Dotan.
26) Add SKB extension infrastructure. This consolidates the handling of
the auxiliary SKB data used by IPSEC and bridge netfilter, and is
designed to support the needs to MPTCP which could be integrated in
the future.
27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan.

A follow-up patch will add a notifier type NETDEV_PRE_CHANGEADDR, which
allows vetoing of MAC address changes. One prominent path to that
notification is through dev_set_mac_address(). Therefore give this
function an extack argument, so that it can be packed together with the
notification. Thus a textual reason for rejection (or a warning) can be
communicated back to the user.

Pull x86 platform driver updates from Andy Shevchenko:
- The USB Power Delivery discrete components now can be enumerated by
i2c-multi-instantiate driver via several resources under single ACPI
device node (ACPI ID is INT3515).
- Touchscreen support is added for the Mediacom Flexbook Edge 11.
- Mellanox driver got fixed due to updates in their firmware.
- The power management stub driver for AtomISP v2 is fixed in order to
support Intel Baytrail SoCs where same quirk is needed for S0ix to
work.
- Special key handling has been fixed for Favorites hotkey on Thinkpad,
and Screen LOCK on ASUS.
- Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been
updated to support this.
- Few cleanups related to debugfs have been made in Intel IPS and Intel
PMC drivers. Besides that Intel PMC has been extended to show more
detailed information about Latency Tolerance

The ACPI device with INT3515 _HID is representing a complex USB PD
hardware infrastructure which includes several I2C slave ICs.
We add an ID to the I2C multi instantiate list to enumerate
all I2C slaves correctly.

As commented in the struct's definition there shouldn't be anything
underneath its 'priv[0]' member as it would break some macros.
The patch converts the broken_suspend into a bit-field and relocates it
next to to the rest of bit-fields.

The HP lt4132 is a rebranded Huawei ME906s-158 LTE modem.
The interface with protocol 0x16 is "CDC ECM & NCM" according to the *.inf
files included with the Windows driver. Attaching the option driver to it
doesn't result in a /dev/ttyUSB* device being created, so I've excluded it.
Note that it is also excluded for corresponding Huawei-branded devices, cf.
commit d544db293a44 ("USB: support new huawei devices in option.c").

The code to prevent a bus suspend if a USB3 port was still in link training
also reacted to USB2 port polling state.
This caused bus suspend to busyloop in some cases.
USB2 polling state is different from USB3, and should not prevent bus
suspend.
Limit the USB3 link training state check to USB3 root hub ports only.
The origial commit went to stable so this need to be applied there as well

The USB-serial console implementation has never reported the actual
terminal settings used. Despite storing the corresponding cflags in its
struct console, these were never honoured on later tty open() where the
tty termios would be left initialised to the driver defaults.
Unlike the serial console implementation, the USB-serial code calls
subdriver open() already at console setup. While calling set_termios()
and write() before open() looks like it could work for some USB-serial
drivers, others definitely do not expect this, so modelling this after
serial core is going to be intrusive, if at all possible.
Instead, use a (renamed) tty helper to save the termios data used at
console setup so that the tty termios reflects the actual terminal
settings after a subsequent tty open().
Note that the calls to tty_init_termios() (tty_driver_install()) and
tty_save_termios() are serialised using the disconnect mutex.
This specifically fixes a regression that was triggered by a recent
change adding software flow control to the pl2303 driver: a getty trying
to disable flow control while leaving the baud rate unchanged would now
also set the baud rate to the driver default (prior to the flow-control
change this had been a noop).
Fixes: 7041d9c3f01b ("USB: serial: pl2303: add support for tx xon/xoff flow control")

Don't allow USB3 U1 or U2 if the latency to wake up from the U-state
reaches the service interval for a periodic endpoint.
This is according to xhci 1.1 specification section 4.23.5.2 extra note:
"Software shall ensure that a device is prevented from entering a U-state
where its worst case exit latency approaches the ESIT."
Allowing too long exit latencies for periodic endpoint confuses xHC
internal scheduling, and new devices may fail to enumerate with a
"Not enough bandwidth for new device state" error from the host.

Occasionally AMD SNPS 3.0 xHC does not respond to
CSS when set, also it does not flag anything on SRE and HCE
to point the internal xHC errors on USBSTS register. This stalls
the entire system wide suspend and there is no point in stalling
just because of xHC CSS is not responding.
To work around this problem, if the xHC does not flag
anything on SRE and HCE, we can skip the CSS
timeout and allow the system to continue the suspend. Once the
system resume happens we can internally reset the controller
using XHCI_RESET_ON_RESUME quirk

Some lower volume SanDisk Ultra Flair in 16GB, which the VID:PID is
in 0781:5591, will aggressively request LPM of U1/U2 during runtime,
when using this thumb drive as the OS installation key we found the
device will generate failure during U1 exit path making it dropped
from the USB bus, this causes a corrupted installation in system at
the end.
i.e.,

Analyzed the USB trace in the link layer we realized it is because
of the 6-ms timer of tRecoveryConfigurationTimeout which documented
on the USB 3.2 Revision 1.0, the section 7.5.10.4.2 of "Exit from
Recovery.Configuration"; device initiates U1 exit -> Recovery.Active
-> Recovery.Configuration, then the host timer timeout makes the link
transits to eSS.Inactive -> Rx.Detect follows by a Warm Reset.
Interestingly, the other higher volume of SanDisk Ultra Flair sharing
the same VID:PID, such as 64GB, would not request LPM during runtime,
it sticks at U0 always, thus disabling LPM does not affect those thumb
drives at all.
The same odd occures in SanDisk Ultra Fit 16GB, VID:PID in 0781:5583.

The problem is caused by use of a static array to store
environment-string pointers. When the routine is called by multiple
threads concurrently, the pointers from one thread can overwrite those
from another.
The solution is to use an ordinary automatic array instead of a static
array.

list_for_each_entry_safe() is not safe for deleting entries from the
list if the spin lock, which protects it, is released and reacquired during
the list iteration. Fix this issue by replacing this construction with
a simple check if list is empty and removing the first entry in each
iteration. This is almost equivalent to a revert of the commit mentioned in
the Fixes: tag.
This patch fixes following issue:

We currently crash if usb_add_gadget_udc_release() fails, since the
udc->done is not initialized until in the remove function.
Furthermore, on module removal the udc data is accessed although
the release function is already triggered by usb_del_gadget_udc()
early in the function.
Fix by rewriting the release and remove functions, basically moving
all the cleanup into the release function, and doing the completion
only in the module removal case.
The patch fixes omap_udc module probe with a failing gadged, and also
allows the removal of omap_udc. Tested by running "modprobe omap_udc;
modprobe -r omap_udc" in a loop.

USB3 roothub might autosuspend before a plugged USB3 device is detected,
causing USB3 device enumeration failure.
USB3 devices don't show up as connected and enabled until USB3 link trainig
completes. On a fast booting platform with a slow USB3 link training the
link might reach the connected enabled state just as the bus is suspending.
If this device is discovered first time by the xhci_bus_suspend() routine
it will be put to U3 suspended state like the other ports which failed to
suspend earlier.
The hub thread will notice the connect change and resume the bus,
moving the port back to U0
This U0 -> U3 -> U0 transition right after being connected seems to be
too much for some devices, causing them to first go to SS.Inactive state,
and finally end up stuck in a polling state with reset asserted
Fix this by failing the bus suspend if a port has a connect change or is
in a polling state in xhci_bus_suspend().
Don't do any port changes until all ports are checked, buffer all port
changes and only write them in the end if suspend can proceed

This will clear the USB_PORT_FEAT_C_CONNECTION bit in case of a hub port reset
only if a device is was attached to the hub port before resetting the hub port.
Using a Lenovo T480s attached to the ultra dock it was not possible to detect
some usb-c devices at the dock usb-c ports because the hub_port_reset code
will clear the USB_PORT_FEAT_C_CONNECTION bit after the actual hub port reset.
Using this device combo the USB_PORT_FEAT_C_CONNECTION bit was set between the
actual hub port reset and the clear of the USB_PORT_FEAT_C_CONNECTION bit.
This ends up with clearing the USB_PORT_FEAT_C_CONNECTION bit after the
new device was attached such that it was not detected.
This patch will not clear the USB_PORT_FEAT_C_CONNECTION bit if there is
currently no device attached to the port before the hub port reset.
This will avoid clearing the connection bit for new attached devices.

Current check for the last extra TRB for zero and unaligned transfers
does not account for isoc OUT. The last TRB of the Buffer Descriptor for
isoc OUT transfers will be retired with HWO=0. As a result, we won't
return early. The req->remaining will be updated to include the BUFSIZ
count of the extra TRB, and the actual number of transferred bytes
calculation will be wrong.
To fix this, check whether it's a short or zero packet and the last TRB
chain bit to return early.

Implement workaround for ThunderX2 Errata-129 (documented in
CN99XX Known Issues" available at Cavium support site).
As per ThunderX2errata-129, USB 2 device may come up as USB 1
if a connection to a USB 1 device is followed by another connection to
a USB 2 device, the link will come up as USB 1 for the USB 2 device.
Resolution: Reset the PHY after the USB 1 device is disconnected.
The PHY reset sequence is done using private registers in XHCI register
space. After the PHY is reset we check for the PLL lock status and retry
the operation if it fails. From our tests, retrying 4 times is sufficient.
Add a new quirk flag XHCI_RESET_PLL_ON_DISCONNECT to invoke the workaround
in handle_xhci_port_status().

Realtek USB3.0 Card Reader [0bda:0328] reports wrong port status on
Cannon lake PCH USB3.1 xHCI [8086:a36d] after resume from S3,
after clear port reset it works fine.
Since this device is registered on USB3 roothub at boot,
when port status reports not superspeed, xhci_get_port_status will call
an uninitialized completion in bus_state[0].
Kernel will hang because of NULL pointer.
Restrict the USB2 resume status check in USB2 roothub to fix hang issue.

USB2 hcd. Interrupts for port status changes may still occur for USB3
ports after the shared_hcd is freed, causing NULL pointer dereference.

Ensure that the shared_hcd pointer is valid when calling usb_put_hcd()
The shared_hcd is removed and freed in xhci by first calling
usb_remove_hcd(xhci->shared_hcd), and later
usb_put_hcd(xhci->shared_hcd)
Afer commit fe190ed0d602 ("xhci: Do not halt the host until both HCD have
disconnected their devices.") the shared_hcd was never properly put as
xhci->shared_hcd was set to NULL before usb_put_hcd(xhci->shared_hcd) was
called.
shared_hcd (USB3) is removed before primary hcd (USB2).
While removing the primary hcd we might need to handle xhci interrupts
to cleanly remove last USB2 devices, therefore we need to set
xhci->shared_hcd to NULL before removing the primary hcd to let xhci
interrupt handler know shared_hcd is no longer available.
xhci-plat.c, xhci-histb.c and xhci-mtk first create both their hcd's before
adding them. so to keep the correct reverse removal order use a temporary
shared_hcd variable for them.
For more details see commit 4ac53087d6d4 ("usb: xhci: plat: Create both
HCDs before adding them")
