Currently, rxrpc gives the connection's work item a ref on the connection
when it queues it - and this is called from the timer expiration function.
The problem comes when queue_work() fails (ie. the work item is already
queued): the timer routine must put the ref - but this may cause the
cleanup code to run.
This has the unfortunate effect that the cleanup code may then be run in
softirq context - which means that any spinlocks it might need to touch
have to be guarded to disable softirqs (ie. they need a "_bh" suffix).
(1) Don't give a ref to the work item.
(2) Simplify handling of service connections by adding a separate active
count so that the refcount isn't also used for this.
(3) Connection destruction for both client and service connections can
then be cleaned up by putting rxrpc_put_connection() out of line and
making a tidy progression through the destruction code (offloaded to a
workqueue if put from softirq or processor function context). The RCU
part of the cleanup then only deals with the freeing at the end.
(4) Make rxrpc_queue_conn() return immediately if it sees the active count
is -1 rather then queuing the connection.
(5) Make sure that the cleanup routine waits for the work item to
complete.
(6) Stash the rxrpc_net pointer in the conn struct so that the rcu free
routine can use it, even if the local endpoint has been freed.
Unfortunately, neither the timer nor the work item can simply get around
the problem by just using refcount_inc_not_zero() as the waits would still
have to be done, and there would still be the possibility of having to put
the ref in the expiration function.
Note the connection work item is mostly going to go away with the main
event work being transferred to the I/O thread, so the wait in (6) will
become obsolete.

Currently, rxrpc gives the call timer a ref on the call when it starts it
and this is passed along to the workqueue by the timer expiration function.
The problem comes when queue_work() fails (ie. the work item is already
queued): the timer routine must put the ref - but this may cause the
cleanup code to run.
This has the unfortunate effect that the cleanup code may then be run in
softirq context - which means that any spinlocks it might need to touch
have to be guarded to disable softirqs (ie. they need a "_bh" suffix).
Fix this by:
(1) Don't give a ref to the timer.
(2) Making the expiration function not do anything if the refcount is 0.
Note that this is more of an optimisation.
(3) Make sure that the cleanup routine waits for timer to complete.
However, this has a consequence that timer cannot give a ref to the work
item. Therefore the following fixes are also necessary:
(4) Don't give a ref to the work item.
(5) Make the work item return asap if it sees the ref count is 0.
(6) Make sure that the cleanup routine waits for the work item to
complete.
Unfortunately, neither the timer nor the work item can simply get around
the problem by just using refcount_inc_not_zero() as the waits would still
have to be done, and there would still be the possibility of having to put
the ref in the expiration function.
Note the call work item is going to go away with the work being transferred
to the I/O thread, so the wait in (6) will become obsolete.

Implement an in-kernel rxperf server to allow kernel-based rxrpc services
to be tested directly, unlike with AFS where they're accessed by the

This is implemented as a module that, if loaded, opens UDP port 7009
(afs3-rmtsys) and listens on it for incoming calls. Calls can be generated
using the rxperf command shipped with OpenAFS, for example.

mptcp: MSG_FASTOPEN and TFO listener side support
Before this series, only the initiator of a connection was able to combine
both TCP FastOpen and MPTCP when using TCP_FASTOPEN_CONNECT socket option.
These new patches here add (in theory) the full support of TFO with MPTCP,
which means:
- MSG_FASTOPEN sendmsg flag support (patch 1/8)
- TFO support for the listener side (patches 2-5/8)
- TCP_FASTOPEN socket option (patch 6/8)
- TCP_FASTOPEN_KEY socket option (patch 7/8)
To support TFO for the server side, a few preparation patches are needed
(patches 2 to 5/8). Some of them were inspired by a previous work from
Benjamin Hesmans.
Note that TFO support with MPTCP has been validated with selftests
(patch 8/8) but also with Packetdrill tests running with a modified
but still very WIP version supporting MPTCP. Both the modified tool
and the tests are available online:
https://github.com/multipath-tcp/packetdrill/

This patch first adds TFO support in mptcp_connect.c.
This can be enabled via a new option: -o MPTFO.
Once enabled, the TCP_FASTOPEN socket option is enabled for the server
side and a sendto() with MSG_FASTOPEN is used instead of a connect() for
the client side.
Note that the first SYN has a limit of bytes it can carry. In other
words, it is allowed to send less data than the provided one. We then
need to track more status info to properly allow the next sendmsg()
starting from the next part of the data to send the rest.
Also in TFO scenarios, we need to completely spool the partially xmitted
buffer -- and account for that -- before starting sendfile/mmap xmit,
otherwise the relevant tests will fail.

The send_synack() needs to be overridden for MPTCP to support TFO for
two reasons:
- There is not be enough space in the TCP options if the TFO cookie has
to be added in the SYN+ACK with other options: MSS (4), SACK OK (2),
Timestamps (10), Window Scale (3+1), TFO (10+2), MP_CAPABLE (12).
MPTCPv1 specs -- RFC 8684, section B.1 [1] -- suggest to drop the TCP
timestamps option in this case.
- The data received in the SYN has to be handled: the SKB can be
dequeued from the subflow sk and transferred to the MPTCP sk. Counters
need to be updated accordingly and the application can be notified at
the end because some bytes have been received.

Currently the initial ack sequence is generated on demand whenever
it's requested and the remote key is handy. The relevant code is
scattered in different places and can lead to multiple, unneeded,
crypto operations.
This change consolidates the ack sequence generation code in a single
helper, storing the sequence number at the subflow level.
The above additionally saves a few conditional in fast-path and will

This reverts commit c0071be0e1.
The cited commit removed the validity checks which initialized the
window_sz and never removed the use of the now uninitialized variable,
so now we are left with wrong value in the window size and the following
clang warning: [-Wuninitialized]
drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c:232:45:
warning: variable 'window_sz' is uninitialized when used here
MLX5_SET(macsec_aso, aso_ctx, window_size, window_sz);
Revet at this time to address the clang issue due to lack of time to
test the proper solution.
Fixes: c0071be0e1 ("net/mlx5e: MACsec, remove replay window size limitation in offload path")

Add support for reporting link modes,
including `Supported link modes` and `Advertised link modes`,
via ethtool $DEV.
A new command `SPCODE_READ_MEDIA` is added to read info from
management firmware. Also, the mapping table `nfp_eth_media_table`
associates the link modes between NFP and kernel. Both of them
help to support this ability.

As the return value is not 0 only in case there is no such notifier
block registered, add a WARN_ON_ONCE() to yell about it.

Horatiu Vultur says:
====================
Add support for lan966x IS2 VCAP
This provides initial support for lan966x for 'tc' traffic control
userspace tool and its flower filter. For this is required to use
the VCAP library.
Currently supported flower filter keys and actions are:
- source and destination MAC address keys
- trap action

On lan966x the layout of the vcap memory is different than on sparx5.

Implement vcap_operations and enable default port keyset configuration
for each port. Now it is possible actually write/read/move entries in
the VCAP.

Extend matchall with action goto. This is needed to enable the lookup in
the VCAP. It is needed to connect chain 0 to a chain that is recognized
by the HW.

Currently the only supported action is ACTION_TRAP and the only
dissector is ETH_ADDRS. Others will be added in future patches.
