BT core driver should addtionally check LMP feature bit
"Erroneous Data Reporting" instead of quirk
HCI_QUIRK_BROKEN_ERR_DATA_REPORTING set by BT device driver to decide if
HCI commands HCI_Read|Write_Default_Erroneous_Data_Reporting are broken.
BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 2, Part C | page 587
This feature indicates whether the device is able to support the
Packet_Status_Flag and the HCI commands HCI_Write_Default_-
Erroneous_Data_Reporting and HCI_Read_Default_Erroneous_-
Data_Reporting.
the quirk was introduced by 'commit cde1a8a992 ("Bluetooth: btusb: Fix
and detect most of the Chinese Bluetooth controllers")' to mark HCI
commands HCI_Read|Write_Default_Erroneous_Data_Reporting broken by BT
device driver, but the reason why these two HCI commands are broken is
that feature "Erroneous Data Reporting" is not enabled by firmware, this
scenario is illustrated by below log of QCA controllers with USB I/F:

There are some synchronization issues(amt->status, amt->req_cnt, etc)
if the interface is in gateway mode because gateway message handlers
are processed concurrently.
This applies a work queue for processing these messages instead of
expanding the locking context.
So, the purposes of this patch are to fix exist race conditions and to make
gateway to be able to validate a gateway status more correctly.
When the AMT gateway interface is created, it tries to establish to relay.
The establishment step looks stateless, but it should be managed well.
In order to handle messages in the gateway, it saves the current
status(i.e. AMT_STATUS_XXX).
This patch makes gateway code to be worked with a single thread.
Now, all messages except the multicast are triggered(received or
delay expired), and these messages will be stored in the event
queue(amt->events).
Then, the single worker processes stored messages asynchronously one
by one.
The multicast data message type will be still processed immediately.
Now, amt->lock is only needed to access the event queue(amt->events)
if an interface is the gateway mode.

recvmsg() in TLS gets data from the skb list (rx_list) or fresh
skbs we read from TCP via strparser. The former holds skbs which were
already decrypted for peek or decrypted and partially consumed.
tls_wait_data() only notices appearance of fresh skbs coming out
of TCP (or psock). It is possible, if there is a concurrent call
to peek() and recv() that the peek() will move the data from input
to rx_list without recv() noticing. recv() will then read data out
of order or never wake up.
This is not a practical use case/concern, but it makes the self
tests less reliable. This patch solves the problem by allowing
only one reader in.
Because having multiple processes calling read()/peek() is not
normal avoid adding a lock and try to fast-path the single reader
case.

- SMCR_VIRT_CONT_BUFS, which means use virtually contiguous
buffers in case of physically contiguous memory is scarce.

Commit e21145a987 ("ipv4: namespacify ip_early_demux sysctl knob") made
it possible to enable/disable early_demux on a per-netns basis. Then, we
introduced two knobs, tcp_early_demux and udp_early_demux, to switch it for
TCP/UDP in commit dddb64bcb3 ("net: Add sysctl to toggle early demux for
tcp and udp"). However, the .proc_handler() was wrong and actually
disabled us from changing the behaviour in each netns.
We can execute early_demux if net.ipv4.ip_early_demux is on and each proto
.early_demux() handler is not NULL. When we toggle (tcp|udp)_early_demux,
the change itself is saved in each netns variable, but the .early_demux()
handler is a global variable, so the handler is switched based on the
init_net's sysctl variable. Thus, netns (tcp|udp)_early_demux knobs have
nothing to do with the logic. Whether we CAN execute proto .early_demux()
is always decided by init_net's sysctl knob, and whether we DO it or not is
by each netns ip_early_demux knob.
This patch namespacifies (tcp|udp)_early_demux again. For now, the users
of the .early_demux() handler are TCP and UDP only, and they are called
directly to avoid retpoline. So, we can remove the .early_demux() handler
from inet6?_protos and need not dereference them in ip6?_rcv_finish_core().
If another proto needs .early_demux(), we can restore it at that time.
