A peer node is considered down if there are no
active links (or) lost contact to the node. In current implementation,
a peer node instance is deleted either if
a) TIPC module is removed (or)
b) Application can use a netlink/iproute2 interface to delete a
specific down node.
Thus, a down node instance lives in the system forever, unless the
application explicitly removes it.
We fix this by deleting the nodes which are down for
a specified amount of time (5 minutes).
Existing node supervision timer is used to achieve this.

r8169: remove TBI 1000BaseX support
The very first version of RTL8169 from 2002 (and only this one) has
support for a TBI 1000BaseX fiber interface. The TBI support in the
driver makes switching to phylib tricky, so best would be to get
rid of it. I found no report from anybody using a device with RTL8169
and fiber interface, also the vendor driver doesn't support this mode
(any longer).
So remove TBI support and bail out with a message if a card with
activated TBI is detected. If there really should be any user of it
out there, we could add a stripped-down version of the driver
supporting chip version 01 and TBI only (and maybe move it to
staging).

tipc: eliminate buffer cloning in function tipc_msg_extract()
The function tipc_msg_extract() is using skb_clone() to clone inner
messages from a message bundle buffer. Although this method is safe,
it has an undesired effect that each buffer clone inherits the
true-size of the bundling buffer. As a result, the buffer clone
almost always ends up with being copied anyway by the message
validation function. This makes the cloning into a sub-optimization.
In this commit we take the consequence of this realization, and copy
each inner message to a separately allocated buffer up front in the

As a bonus we can now eliminate the two cases where we had to copy
re-routed packets that may potentially go out on the wire again.

This patch adds the base infrastructure for SMC-D and ISM devices to

This interface allows an ISM driver to register ISM devices in SMC. In

SMC uses these ops to execute SMC specific operations on or transfer
data over the device.
* Core SMC-D link group, connection, and buffer support:
Link groups, SMC connections and SMC buffers (in smc_core) are

* SMC type checks:

sctp: add support for SCTP_REUSE_PORT sockopt
This feature is actually already supported by sk->sk_reuse which can be
set by socket level opt SO_REUSEADDR. But it's not working exactly as
RFC6458 demands in section 8.1.27, like:
- This option only supports one-to-one style SCTP sockets
- This socket option must not be used after calling bind()
or sctp_bindx().
Besides, SCTP_REUSE_PORT sockopt should be provided for user's programs.
Otherwise, the programs with SCTP_REUSE_PORT from other systems will not
work in linux.
To separate it from the socket level version, this patch adds 'reuse' in
sctp_sock and it works pretty much as sk->sk_reuse, but with some extra
setup limitations that are needed when it is being enabled.
"It should be noted that the behavior of the socket-level socket option
to reuse ports and/or addresses for SCTP sockets is unspecified", so it
leaves SO_REUSEADDR as is for the compatibility.
Note that the name SCTP_REUSE_PORT is somewhat confusing, as its
functionality is nearly identical to SO_REUSEADDR, but with some
extra restrictions. Here it uses 'reuse' in sctp_sock instead of
'reuseport'. As for sk->sk_reuseport support for SCTP, it will be
added in another patch.
Thanks to Neil to make this clear.
v1->v2:
- add sctp_sk->reuse to separate it from the socket level version.
v2->v3:
- improve changelog according to Marcelo's suggestion.

net: preserve sock reference when scrubbing the skb.
The sock reference is lost when scrubbing the packet and that breaks
TSQ (TCP Small Queues) and XPS (Transmit Packet Steering) causing
performance impacts of about 50% in a single TCP stream when crossing
network namespaces.
XPS breaks because the queue mapping stored in the socket is not
available, so another random queue might be selected when the stack
needs to transmit something like a TCP ACK, or TCP Retransmissions.
That causes packet re-ordering and/or performance issues.
TSQ breaks because it orphans the packet while it is still in the
host, so packets are queued contributing to the buffer bloat problem.
Preserving the sock reference fixes both issues. The socket is
orphaned anyways in the receiving path before any relevant action,
but the transmit side needs some extra checking included in the
first patch.
The first patch will update netfilter to check if the socket
netns is local before use it.
The second patch removes the skb_orphan() from the skb_scrub_packet()
and improve the documentation.
ChangeLog:
- split into two (Eric)
- addressed Paolo's offline feedback to swap the checks in xt_socket.c
to preserve original behavior.
- improved ip-sysctl.txt (reported by Cong)

Extend slotting with support for non-uniform distributions. This is
similar to netem's non-uniform distribution delay feature.
Commit f043efeae2f1 ("netem: support delivering packets in delayed
time slots") added the slotting feature to approximate the behaviors
of media with packet aggregation but only supported a uniform
distribution for delays between transmission attempts. Tests with TCP
BBR with emulated wifi links with non-uniform distributions produced
more useful results.
The syntax and use of the distribution table is the same as in the
non-uniform distribution delay feature. A file DISTRIBUTION must be
present in TC_LIB_DIR (e.g. /usr/lib/tc) containing numbers scaled by
NETEM_DIST_SCALE. A random value x is selected from the table and it
takes DELAY + ( x * JITTER ) as delay. Correlation between values is not
supported.

Normal distribution delay with mean = 800us and stdev = 100us.
