[ Upstream commit e848dbd364aca44c9d23c04bef964fab79e2b34f ]
Because mSBC frames do not need to be aligned to the SCO packet
boundary. Using USB ALT 3 let HCI payload >= 60 bytes, let mSBC
data satisfy 60 Bytes avoid payload unaligned situation and fixed
some headset no voise issue.
USB Alt 3 supported also need HFP support transparent MTU in 72 Bytes.

[ Upstream commit 0324d19cb99804d99e42c990b8b1e191575a091b ]
This patch adds the 0cf3:e500 Bluetooth device (from a QCA9377 board) as a
QCA_ROME device. It appears to be functionally identical to another device
ID, also from a QCA9377 board, which was previously marked as QCA_ROME in
0a03f98b98c201191e3ba15a0e33f46d8660e1fd
("Bluetooth: Add a new 04ca:3015 QCA_ROME device").
Without this patch, the WiFi side of the QCA9377 board is slow or unusable
when the Bluetooth side is in use.
See https://askubuntu.com/a/1137852 for another report of QCA_ROME fixing
this issue for this device ID.

In qca_power_shutdown() qcadev local variable is
initialized by hu->serdev.dev private data, but
hu->serdev can be NULL and there is a check for it.
Since, qcadev is not used before
if (!hu->serdev)
return;
we can move its initialization after this "if" to
prevent GPF.

[ Upstream commit 3b830a9c34d5897be07176ce4e6f2d75e2c8cfd7 ]
The tty line discipline .read() function was passed the final user
pointer destination as an argument, which doesn't match the 'write()'
function, and makes it very inconvenient to do a splice method for
ttys.
This is a conversion to use a kernel buffer instead.
NOTE! It does this by passing the tty line discipline ->read() function
an additional "cookie" to fill in, and an offset into the cookie data.
The line discipline can fill in the cookie data with its own private
information, and then the reader will repeat the read until either the
cookie is cleared or it runs out of data.
The only real user of this is N_HDLC, which can use this to handle big
packets, even if the kernel buffer is smaller than the whole packet.

[ Upstream commit afe0b1c86458f121b085271e4f3034017a90d4a3 ]
In hci_uart_write_work, there is a loop/goto checking the value of
HCI_UART_TX_WAKEUP. If HCI_UART_TX_WAKEUP is set again, it keeps trying
hci_uart_dequeue; otherwise, it clears HCI_UART_SENDING and returns.
In hci_uart_tx_wakeup, if HCI_UART_SENDING is already set, it sets
HCI_UART_TX_WAKEUP, skips schedule_work and assumes the running/pending
hci_uart_write_work worker will do hci_uart_dequeue properly.
However, if the HCI_UART_SENDING check in hci_uart_tx_wakeup is done after
the loop breaks, but before HCI_UART_SENDING is cleared in
hci_uart_write_work, the schedule_work is skipped incorrectly.
Fix this race by changing the order of HCI_UART_SENDING and
HCI_UART_TX_WAKEUP modification.

commit 234f414efd1164786269849b4fbb533d6c9cdbbf upstream.
This issue starts from linux-5.10-rc1, I reproduced this issue on my
Dell Inspiron 7447 with BT adapter 0cf3:e005, the kernel will print
out: "Bluetooth: hci0: don't support firmware rome 0x31010000", and
someone else also reported the similar issue to bugzilla #211571.
I found this is a regression introduced by 'commit b40f58b97386
("Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support"), the
patch assumed that if high ROM version is not zero, it is an adapter
on WCN6855, but many old adapters don't need to load rampatch or nvm,
and they have non-zero high ROM version.
To fix it, let the driver match the rom_version in the
qca_devices_table first, if there is no entry matched, check the
high ROM version, if it is not zero, we assume this adapter is ready
to work and no need to load rampatch and nvm like previously.

commit 517b693351a2d04f3af1fc0e506ac7e1346094de upstream.
When alt mode 6 is not available, fallback to the kernel <= 5.7 behavior
of always using alt mode 1.
Prior to kernel 5.8, btusb would always use alt mode 1 for WBS (Wide
Band Speech aka mSBC aka transparent SCO). In commit baac6276c0a9
("Bluetooth: btusb: handle mSBC audio over USB Endpoints") this
was changed to use alt mode 6, which is the recommended mode in the
Bluetooth spec (Specifications of the Bluetooth System, v5.0, Vol 4.B
§2.2.1). However, many if not most BT USB adapters do not support alt
mode 6. In fact, I have been unable to find any which do.
In kernel 5.8, this was changed to use alt mode 6, and if not available,
use alt mode 0. But mode 0 has a zero byte max packet length and can
not possibly work. It is just there as a zero-bandwidth dummy mode to
work around a USB flaw that would prevent device enumeration if
insufficient bandwidth were available for the lowest isoc mode
supported.
In effect, WBS was broken for all USB-BT adapters that do not support
alt 6, which appears to nearly all of them.
Then in commit 461f95f04f19 ("Bluetooth: btusb: USB alternate setting 1 for
WBS") the 5.7 behavior was restored, but only for Realtek adapters.
I've tested a Broadcom BRCM20702A and CSR 8510 adapter, both work with
the 5.7 behavior and do not with the 5.8.
So get rid of the Realtek specific flag and use the 5.7 behavior for all
adapters as a fallback when alt 6 is not available. This was the
kernel's behavior prior to 5.8 and I can find no adapters for which it
is not correct. And even if there is an adapter for which this does not
work, the current behavior would be to fall back to alt 0, which can not
possibly work either, and so is no better.

commit 5c3b5796866f85354a5ce76a28f8ffba0dcefc7e upstream.
There have been multiple revisions of the patch fix the h5->rx_skb
leak. Accidentally the first revision (which is buggy) and v5 have
both been merged:
v1 commit 70f259a3f427 ("Bluetooth: hci_h5: close serdev device and free
hu in h5_close");
v5 commit 855af2d74c87 ("Bluetooth: hci_h5: fix memory leak in h5_close")
The correct v5 makes changes slightly higher up in the h5_close()
function, which allowed both versions to get merged without conflict.
The changes from v1 unconditionally frees the h5 data struct, this
is wrong because in the serdev enumeration case the memory is
allocated in h5_serdev_probe() like this:
h5 = devm_kzalloc(dev, sizeof(*h5), GFP_KERNEL);
So its lifetime is tied to the lifetime of the driver being bound
to the serdev and it is automatically freed when the driver gets
unbound. In the serdev case the same h5 struct is re-used over
h5_close() and h5_open() calls and thus MUST not be free-ed in
h5_close().
The serdev_device_close() added to h5_close() is incorrect in the
same way, serdev_device_close() is called on driver unbound too and
also MUST no be called from h5_close().
This reverts the changes made by merging v1 of the patch, so that
just the changes of the correct v5 remain.

commit 70f259a3f4276b71db365b1d6ff1eab805ea6ec3 upstream.
When h5_close() gets called, the memory allocated for the hu gets
freed only if hu->serdev doesn't exist. This leads to a memory leak.
So when h5_close() is requested, close the serdev device instance and
free the memory allocated to the hu entirely instead.

bcdDevice val of 0x0134
[ Upstream commit d74e0ae7e03032b47b8631cc1e52a7ae1ce988c0 ]
Commit cde1a8a99287 ("Bluetooth: btusb: Fix and detect most of the
Chinese Bluetooth controllers") made the detection of fake controllers
more generic fixing it for much of the newer fakes / clones.
But this does not work for a fake CSR controller with a bcdDevice
value of 0x0134, which was correctly identified as fake before
this change.
Add an extra check for this special case, checking for a combination
of a bcdDevice value of 0x0134, together with a lmp_subver of 0x0c5c
and a hci_ver of BLUETOOTH_VER_2_0.
The chip inside this fake dongle is marked as with "clockwise cw6629d".

[ Upstream commit 855af2d74c870d747bf53509f8b2d7b9dc9ee2c3 ]
When h5_close() is called, h5 is directly freed when !hu->serdev.
However, h5->rx_skb is not freed, which causes a memory leak.
Freeing h5->rx_skb and setting it to NULL, fixes this memory leak.
Fixes: ce945552fde4 ("Bluetooth: hci_h5: Add support for serdev enumerated devices")

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

Pull networking updates from Jakub Kicinski:
- Add redirect_neigh() BPF packet redirect helper, allowing to limit
stack traversal in common container configs and improving TCP
back-pressure.
Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.
- Expand netlink policy support and improve policy export to user
space. (Ge)netlink core performs request validation according to
declared policies. Expand the expressiveness of those policies
(min/max length and bitmasks). Allow dumping policies for particular
commands. This is used for feature discovery by user space (instead
of kernel version parsing or trial and error).
- Support IGMPv3/MLDv2 multicast listener discovery protocols in
bridge.
- Allow more than 255 IPv4 multicast interfaces.
- Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
packets of TCPv6.
- In Multi-patch TCP (MPTCP) support concurrent transmission of data on
multiple subflows in a load balancing scenario. Enhance advertising
addresses via the RM_ADDR/ADD_ADDR options.
- Support SMC-Dv2 version of SMC, which enables multi-subnet
deployments.
- Allow more calls to same peer in RxRPC.
- Support two new Controller Area Network (CAN) protocols - CAN-FD and
ISO 15765-2:2016.
- Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
kernel problem.
- Add TC actions for implementing MPLS L2 VPNs.
- Improve nexthop code - e.g. handle various corner cases when nexthop
objects are removed from groups better, skip unnecessary
notifications and make it easier to offload nexthops into HW by
converting to a blocking notifier.
- Support adding and consuming TCP header options by BPF programs,
opening the doors for easy experimental and deployment-specific TCP
option use.
- Reorganize TCP congestion control (CC) initialization to simplify
life of TCP CC implemented in BPF.
- Add support for shipping BPF programs with the kernel and loading
them early on boot via the User Mode Driver mechanism, hence reusing
all the user space infra we have.
- Support sleepable BPF programs, initially targeting LSM and tracing.
- Add bpf_d_path() helper for returning full path for given 'struct
path'.
- Make bpf_tail_call compatible with bpf-to-bpf calls.
- Allow BPF programs to call map_update_elem on sockmaps.
- Add BPF Type Format (BTF) support for type and enum discovery, as
well as support for using BTF within the kernel itself (current use
is for pretty printing structures).
- Support listing and getting information about bpf_links via the bpf
syscall.
- Enhance kernel interfaces around NIC firmware update. Allow
specifying overwrite mask to control if settings etc. are reset
during update; report expected max time operation may take to users;
support firmware activation without machine reboot incl. limits of
how much impact reset may have (e.g. dropping link or not).
- Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.
- Adopt or extend devlink use for debug, monitoring, fw update in many
drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx,
dpaa2-eth).
- In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.
- Add XDP support for Intel's igb driver.
- Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.
- Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.
- Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.
- Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.
- Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.
- Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.
- Improve performance for packets which don't require much offloads on
recent Mellanox NICs by 20% by making multiple packets share a
descriptor entry.
- Move chelsio inline crypto drivers (for TLS and IPsec) from the
crypto subtree to drivers/net. Move MDIO drivers out of the phy
directory.
- Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.
- Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

The usb_control_msg_send() and usb_control_msg_recv() calls can return

On new Intel platform the device is provided with INT33E3 ID.
Append it to the list.
This will require ACPI_GPIO_QUIRK_ONLY_GPIOIO to be enabled because
the relevant ASL looks like:
UartSerialBusV2 ( ... )
GpioInt ( ... ) { ... }
GpioIo ( ... ) { ... }
which means that first GPIO resource is an interrupt, while we are expecting it
to be reset one (output). Do the same for host-wake because in case of
GpioInt() the platform_get_irq() will do the job and should return correct
Linux IRQ number. That said, host-wake GPIO can only be GpioIo() resource.
While here, drop commas in terminator lines.

This reverts commit 7ecacafc240638148567742cca41aa7144b4fe1e.
Testing this change on a board with RTL8822CE, I found that enabling
autosuspend has no effect on the stability of the system. The board
continued working after autosuspend, suspend and reboot.
The original commit makes it impossible to enable autosuspend on working
systems so it should be reverted. Disabling autosuspend should be done
via module param or udev in userspace instead.
