We are going to remove the first subflow socket soon, so avoid
the additional indirection via at bind() time. Instead call directly
the recently introduced helpers on the first subflow sock.

The mptcp protocol maintains an additional socket just to easily
invoke a few stream operations on the first subflow. One of
them is bind().
Factor out the helpers operating directly on the struct sock, to
allow get rid of the above dependency in the next patch without
duplicating the existing code.
No functional changes intended.

We are going to remove the first subflow socket soon, so avoid
the additional indirection via at connect time, calling directly
into the sock-level connect() ops.
The sk-level connect never return -EINPROGRESS, cleanup the error
path accordingly. Additionally, the ssk status on error is always
TCP_CLOSE. Avoid unneeded access to the subflow sk state.

The MPTCP protocol currently clears the msk token both at connect() and
listen() time. That is needed to deal with failing connect() calls that
can create a new token while leaving the sk in TCP_CLOSE,SS_UNCONNECTED
status and thus allowing later connect() and/or listen() calls.
Let's deal with such failures explicitly, cleaning the token in a timely
manner and avoid the confusing early mptcp_token_destroy().

The debug message in tcp_retransmit_timer() is slightly wrong, because
they could be printed even if we did not receive a new ACK packet from
the remote peer.
Change it to probing zero-window, as it is a expected case now. The
description may be not correct.
Adding the duration since the last ACK we received, and the duration of
the retransmission, which are useful for debugging.
And the message now like this:
Probing zero-window on 127.0.0.1:9999/46946, seq=3737778959:3737791503, recv 209ms ago, lasting 209ms

In tcp_retransmit_timer(), a window shrunk connection will be regarded
as timeout if 'tcp_jiffies32 - tp->rcv_tstamp > TCP_RTO_MAX'. This is not
right all the time.
The retransmits will become zero-window probes in tcp_retransmit_timer()
if the 'snd_wnd==0'. Therefore, the icsk->icsk_rto will come up to
TCP_RTO_MAX sooner or later.
However, the timer can be delayed and be triggered after 122877ms, not
TCP_RTO_MAX, as I tested.
Therefore, 'tcp_jiffies32 - tp->rcv_tstamp > TCP_RTO_MAX' is always true
once the RTO come up to TCP_RTO_MAX, and the socket will die.
Fix this by replacing the 'tcp_jiffies32' with '(u32)icsk->icsk_timeout',
which is exact the timestamp of the timeout.
However, "tp->rcv_tstamp" can restart from idle, then tp->rcv_tstamp
could already be a long time (minutes or hours) in the past even on the
first RTO. So we double check the timeout with the duration of the
retransmission.
Meanwhile, making "2 * TCP_RTO_MAX" as the timeout to avoid the socket
dying too soon.

Fow now, an ACK can update the window in following case, according to
the tcp_may_update_window():
1. the ACK acknowledged new data
2. the ACK has new data
3. the ACK expand the window and the seq of it is valid
Now, we allow the ACK update the window if the window is 0, and the
seq/ack of it is valid. This is for the case that the receiver replies
an zero-window ACK when it is under memory stress and can't queue the new
data.

For now, skb will be dropped when no memory, which makes client keep
retrans util timeout and it's not friendly to the users.
In this patch, we reply an ACK with zero-window in this case to update
the snd_wnd of the sender to 0. Therefore, the sender won't timeout the
connection and will probe the zero-window with the retransmits.

Dropped CIS that are in state BT_OPEN/BT_BOUND, and in state BT_CONNECT
with HCI_CONN_CREATE_CIS unset, should be cleaned up immediately.
Closing CIS ISO sockets should result to the hci_conn be deleted, so
that potentially pending CIG removal can run.
hci_abort_conn cannot refer to them by handle, since their handle is
still unset if Set CIG Parameters has not yet completed.
This fixes CIS not being terminated if the socket is shut down
immediately after connection, so that the hci_abort_conn runs before Set
CIG Parameters completes. See new BlueZ test "ISO Connect Close - Success"

Calling hci_conn_del in __iso_sock_close is invalid. It needs
hdev->lock, but it cannot be acquired there due to lock ordering.
Fix this by doing cleanup via hci_conn_drop.
Return hci_conn with refcount 1 from hci_bind_cis and hci_connect_cis,
so that the iso_conn always holds one reference. This also fixes
refcounting when error handling.
Since hci_conn_abort shall handle termination of connections in any
state properly, we can handle BT_CONNECT socket state in the same way as
BT_CONNECTED.

Some use cases require the user to be informed if BIG synchronization
fails. This commit makes it so that even if the BIG sync established
event arrives with error status, a new hconn is added for each BIS,
and the iso layer is notified about the failed connections.
Unsuccesful bis connections will be marked using the
HCI_CONN_BIG_SYNC_FAILED flag. From the iso layer, the POLLERR event
is triggered on the newly allocated bis sockets, before adding them
to the accept list of the parent socket.
From user space, a new fd for each failed bis connection will be
obtained by calling accept. The user should check for the POLLERR
event on the new socket, to determine if the connection was successful
or not.
The HCI_CONN_BIG_SYNC flag has been added to mark whether the BIG sync
has been successfully established. This flag is checked at bis cleanup,
so the HCI LE BIG Terminate Sync command is only issued if needed.
The BT_SK_BIG_SYNC flag indicates if BIG create sync has been called
for a listening socket, to avoid issuing the command everytime a BIGInfo
advertising report is received.

Since limited tracking device per condition, this feature is to support
tracking multiple devices concurrently.
When a pattern monitor detects the device, this feature issues an address
monitor for tracking that device. Let pattern monitor can keep monitor
new devices.
This feature adds an address filter when receiving a LE monitor device
event which monitor handle is for a pattern, and the controller started
monitoring the device. And this feature also has cancelled the monitor
advertisement from address filters when receiving a LE monitor device
event when the controller stopped monitoring the device specified by an
address and monitor handle.
Below is an example to know the feature adds the address filter.

LE Create CIS command shall not be sent before all CIS Established
events from its previous invocation have been processed. Currently it is
sent via hci_sync but that only waits for the first event, but there can
be multiple.
Make it wait for all events, and simplify the CIS creation as follows:
Add new flag HCI_CONN_CREATE_CIS, which is set if Create CIS has been
sent for the connection but it is not yet completed.
Make BT_CONNECT state to mean the connection wants Create CIS.
On events after which new Create CIS may need to be sent, send it if
possible and some connections need it. These events are:
hci_connect_cis, iso_connect_cfm, hci_cs_le_create_cis,
hci_le_cis_estabilished_evt.
The Create CIS status/completion events shall queue new Create CIS only
if at least one of the connections transitions away from BT_CONNECT, so
that we don't loop if controller is sending bogus events.
This fixes sending multiple CIS Create for the same CIS in the
"ISO AC 6(i) - Success" BlueZ test case:

It is required for some configurations to have multiple BISes as part
of the same BIG.
Similar to the flow implemented for unicast, DEFER_SETUP will also be
used to bind multiple BISes for the same BIG, before starting Periodic
Advertising and creating the BIG.
The user will have to open a new socket for each BIS. By setting the
BT_DEFER_SETUP socket option and calling connect, a new connection
will be added for the BIG and advertising handle set by the socket
QoS parameters. Since all BISes will be bound for the same BIG and
advertising handle, the socket QoS options and base parameters should
match for all connections.
By calling connect on a socket that does not have the BT_DEFER_SETUP
option set, periodic advertising will be started and the BIG will
be created, with a BIS for each previously bound connection. Since
a BIG cannot be reconfigured with additional BISes after creation,
no more connections can be bound for the BIG after the start periodic
advertising and create BIG commands have been queued.
The bis_cleanup function has also been updated, so that the advertising
set and the BIG will not be terminated unless there are no more
bound or connected BISes.
The HCI_CONN_BIG_CREATED connection flag has been added to indicate
that the BIG has been successfully created. This flag is checked at
bis_cleanup, so that the BIG is only terminated if the
HCI_LE_Create_BIG_Complete has been received.
This implementation has been tested on hardware, using the "isotest"
tool with an additional command line option, to specify the number of
BISes to create as part of the desired BIG:
tools/isotest -i hci0 -s 00:00:00:00:00:00 -N 2 -G 1 -T 1
The btmon log shows that a BIG containing 2 BISes has been created:

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, wireless and bpf.
Still trending up in size but the good news is that the "current"
regressions are resolved, AFAIK.
We're getting weirdly many fixes for Wake-on-LAN and suspend/resume
handling on embedded this week (most not merged yet), not sure why.
But those are all for older bugs.
Current release - regressions:
- tls: set MSG_SPLICE_PAGES consistently when handing encrypted data
over to TCP
Current release - new code bugs:
- eth: mlx5: correct IDs on VFs internal to the device (IPU)
Previous releases - regressions:
- phy: at803x: fix WoL support / reporting on AR8032
- bonding: fix incorrect deletion of ETH_P_8021AD protocol VID from
slaves, leading to BUG_ON()
- tun: prevent tun_build_skb() from exceeding the packet size limit
- wifi: rtw89: fix 8852AE disconnection caused by RX full flags
- eth/PCI: enetc: fix probing after 6fffbc7ae137 ("PCI: Honor
firmware's device disabled status"), keep PCI devices around even
if they are disabled / not going to be probed to be able to apply
quirks on them
- eth: prestera: fix handling IPv4 routes with nexthop IDs
Previous releases - always broken:
- netfilter: re-work garbage collection to avoid races between
user-facing API and timeouts
- tunnels: fix generating ipv4 PMTU error on non-linear skbs
- nexthop: fix infinite nexthop bucket dump when using maximum
nexthop ID
- wifi: nl80211: fix integer overflow in nl80211_parse_mbssid_elems()
Misc:
- unix: use consistent error code in SO_PEERPIDFD
- ipv6: adjust ndisc_is_useropt() to include PREFIX_INFO, in prep for
upcoming IETF RFC"
