In order to narrow the interface and dependencies between the topology
server and the subscription/binding table functionality we move struct
tipc_server inside the file server.c. This requires some code
adaptations in other files, but those are mostly minor.
The most important change is that we have to move the start/stop
functions for the topology server to server.c, where they logically
belong anyway.

Since we now have removed struct tipc_subscriber from the code, and
only struct tipc_subscription remains, there is no longer need for long
and awkward prefixes to distinguish between their pertaining functions.
We now change all tipc_subscrp_* prefixes to tipc_sub_*. This is
a purely cosmetic change.

After the previous changes it becomes logical to collapse the two-level
creation of subscription instances into one. We do that here.
We also rename the creation and deletion functions for more consistency.

Because of the requirement for total distribution transparency, users
send subscriptions and receive topology events in their own host format.
It is up to the topology server to determine this format and do the
correct conversions to and from its own host format when needed.
Until now, this has been handled in a rather non-transparent way inside
the topology server and subscriber code, leading to unnecessary
complexity when creating subscriptions and issuing events.
We now improve this situation by adding two new macros, tipc_sub_read()
and tipc_evt_write(). Both those functions calculate the need for
conversion internally before performing their respective operations.
Hence, all handling of such conversions become transparent to the rest
of the code.

The message transmission and reception in the topology server is more
generic than is currently necessary. By basing the funtionality on the
fact that we only send items of type struct tipc_event and always
receive items of struct tipc_subcr we can make several simplifications,
and also get rid of some unnecessary dynamic memory allocations.

It is unnecessary to keep two structures, struct tipc_conn and struct
tipc_subscriber, with a one-to-one relationship and still with different
life cycles. The fact that the two often run in different contexts, and
still may access each other via direct pointers constitutes an additional
hazard, something we have experienced at several occasions, and still
see happening.
We have identified at least two remaining problems that are easier to
fix if we simplify the topology server data structure somewhat.
- When there is a race between a subscription up/down event and a
timeout event, it is fully possible that the former might be delivered
after the latter, leading to confusion for the receiver.
- The function tipc_subcrp_timeout() is executing in interrupt context,
while the following call chain is at least theoretically possible:
tipc_subscrp_timeout()
tipc_subscrp_send_event()
tipc_conn_sendmsg()
conn_put()
tipc_conn_kref_release()
sock_release(sock)
I.e., we end up calling a function that might try to sleep in
interrupt context. To eliminate this, we need to ensure that the
tipc_conn structure and the socket, as well as the subscription
instances, only are deleted in work queue context, i.e., after the
timeout event really has been sent out.
We now remove this unnecessary complexity, by merging data and
functionality of the subscriber structure into struct tipc_conn
and the associated file server.c. We thereafter add a spinlock and
a new 'inactive' state to the subscription structure. Using those,
both problems described above can be easily solved.

The socket handling in the topology server is unnecessarily generic.
It is prepared to handle both SOCK_RDM, SOCK_DGRAM and SOCK_STREAM
type sockets, as well as the only socket type which is really used,
SOCK_SEQPACKET.
We now remove this redundant code to make the code more readable.

This should be a general test architecture, and yet allow specific
tests to be done. Introduce a plugin architecture.
An individual test has 4 stages, setup/execute/verify/teardown. Each
plugin gets a chance to run a function at each stage, plus one call
before all the tests are called ("pre" suite) and one after all the
tests are called ("post" suite). In addition, just before each
command is executed, the plugin gets a chance to modify the command
using the "adjust_command" hook. This makes the test suite quite
flexible.
Future patches will take some functionality out of the tdc.py script and
place it in plugins.
To use the plugins, place the implementation in the plugins directory
and run tdc.py. It will notice the plugins and use them.

Separate the functionality of the command line parameters into "selection"
parameters, "action" parameters and other parameters.
"Selection" parameters are for choosing which tests on which to act.
"Action" parameters are for choosing what to do with the selected tests.
"Other" parameters are for global effect (like "help" or "verbose").
With this commit, we add the ability to name a directory as another
selection mechanism. We can accumulate a number of tests by directory,

This patch adds possibility to get tun device's net namespace fd
in the same way we allow to do that for sockets.
Socket ioctl numbers do not intersect with tun-specific, and there
is already SIOCSIFHWADDR used in tun code. So, SIOCGSKNS number
is choosen instead of custom-made for this functionality.
Note, that open_related_ns() uses plain get_net_ns() and it's safe
(net can't be already dead at this moment):
tun socket is allocated via sk_alloc() with zero last arg (kern = 0).
So, each alive socket increments net::count, and the socket is definitely
alive during ioctl syscall.
Also, common variable net is introduced, so small cleanup in TUNSETIFF
is made.

Currently, the default link tolerance set in struct tipc_bearer only
has effect on links going up after that moment. I.e., a user has to
reset all the node's links across that bearer to have the new value
applied. This is too limiting and disturbing on a running cluster to
be useful.
We now change this so that also already existing links are updated
dynamically, without any need for a reset, when the bearer value is
changed. We leverage the already existing per-link functionality
for this to achieve the wanted effect.

PTP support for DSA and mv88e6xxx driver.
This patchset adds support for using the PTP hardware in switches
supported by the mv88e6xxx driver. The code was produces in
collaboration with Brandon Streiff doing the initial implementation,
and then Richard Cochran and Andrew Lunn making further changes and
cleanups.
The code is sufficient to use ptp4l on a single DSA interface, either
as a master or a slave. Due to the use of an MDIO bus to access the
switch, reading hardware timestamps is slower than what ptp4l
expects. Thus it is necessary to use the option
--tx_timestamp_timeout=32. Heavy use of ethtool -S, or bridge fdb show
can also upset ptp4l. Patches to address this will follow.
Further work is requires to support bridges using Boundary Clock or
Transparent Clock mode.

has also Acked-by: the updates to his initial patchset.

The register interface differs slightly between different models; older
models use a 3-bit operations field, while newer models use a 2-bit
field. The operations values and the special "global port" values are
different between the two. This is a similar split to the differences
in the "Ingress Rate" register between models, so, like in that case,
we call the two variants "6352" and "6390" and create an ops structure
to abstract between the two.

배석진 reported that in some situations, packets for a given 5-tuple
end up being processed by different CPUS.
This involves RPS, and fragmentation.
배석진 is seeing packet drops when a SYN_RECV request socket is
moved into ESTABLISH state. Other states are protected by socket lock.
This is caused by a CPU losing the race, and simply not caring enough.
Since this seems to occur frequently, we can do better and perform
a second lookup.
Note that all needed memory barriers are already in the existing code,
thanks to the spin_lock()/spin_unlock() pair in inet_ehash_insert()
and reqsk_put(). The second lookup must find the new socket,
unless it has already been accepted and closed by another cpu.
Note that the fragmentation could be avoided in the first place by
use of a correct TCP MSS option in the SYN{ACK} packet, but this
does not mean we can not be more robust.
Many thanks to 배석진 for a very detailed analysis.

This patch provides support to add or delete cloud filter for queue
channels created for ADq on VF.
We are using the HW's cloud filter feature and programming it to act
as a TC filter applied to a group of queues.
There are two possible modes for a VF when applying a cloud filter
1. Basic Mode: Intended to apply filters that don't need a VF to be
Trusted. This would include the following
Dest MAC + L4 port
Dest MAC + VLAN + L4 port
2. Advanced Mode: This mode is only for filters with combination that
requires VF to be Trusted.
Dest IP + L4 port
When cloud filters are applied on a trusted VF and for some reason
the same VF is later made as untrusted then all cloud filters
will be deleted. All cloud filters has to be re-applied in
such a case.
Cloud filters are also deleted when queue channel is deleted.
Testing-Hints:
=============
1. Adding Basic Mode filter should be possible on a VF in
Non-Trusted mode.
2. In Advanced mode all filters should be able to be created.
Steps:
======
1. Enable ADq and create TCs using TC mqprio command
2. Apply cloud filter.
3. Turn-off the spoof check.
4. Pass traffic.
Example:
========
1. tc qdisc add dev enp4s2 root mqprio num_tc 4 map 0 0 0 0 1 2 2 3\
queues 2@0 2@2 1@4 1@5 hw 1 mode channel
2. tc qdisc add dev enp4s2 ingress
3. ethtool -K enp4s2 hw-tc-offload on
4. ip link set ens261f0 vf 0 spoofchk off
