Some PHYs will use the 2500BaseX PHY_INTERFACE_MODE when being linked
with a partner using 2.5GBaseT.
Since we can't autonegotiate this speed between the MAC and the PHY, we
need to have the proper comphy support enabled, to make sure we can
safely advertise 2.5G and 1G in BaseT and be able to switch between both
corresponding PHY interface modes. This is now possible since comphy
support was added to this driver.
This commit adds the 2500BaseT mode to the list of supported modes when
using 2500BaseX, and was tested on a setup with an Armada385 and a
88E2010 PHY, both with and without the comphy node in the DT.

Add support for fine-grain timeout support to conntrack action.

specifies a timeout to be associated with this connection.
If no timeout is specified, it acts as is, that is the default
timeout for the connection will be automatically applied.

====================
s390/qeth: updates 2019-03-28
please apply the following patchset to net-next. This reworks the control
IO code in qeth so that we no longer need to poll for cmd completion,
and refactors the IDX setup code to also use this improved IO path.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This converts the IDX code to use qeth_send_control_data(), replacing
a bunch of duplicated IO code and unbounded waits. It also allows the
IDX sequence to benefit from the improved timeout & notify
infrastructure, so that we can eliminate the DOWN -> ACTIVATING -> UP
transition in the channel state machine.
The patch looks rather big, but most of it is a straight-forward
conversion of the old IDX cmd setup & callbacks to the new model.
Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
To avoid concurrency issues, some parts of the cmd setup are delayed
until qeth_send_control_data() holds the IO channel's irq_pending
"lock". Rather than hard-coding those setup steps for each cmd type,
have the cmd provide a callback. This will make it easier to also issue
IDX commands via qeth_send_control_data().

Current code makes it look like qeth_send_control_data_cb() is some

The L2 and L3 .ndo_set_rx_mode callbacks maintain an address cache
to decide which addresses have changed since the last modeset.
When the card is set offline, qeth_l?_stop_card() drains this cache.
This happens only after 1) the net_device has been detached, and
2) any pending RX modeset has completed. Consequently we can access the
cache lock-free.

.ndo_set_rx_mode gets called in process context, but while holding the
addr_list spinlock. Which means we currently can't sleep while
re-programming the HW, and need to poll for IO completion. That's bad,
in particular since receiving the cmd response can fail silently and
we're then polling until the timeout hits.
As a first step towards eliminating the IO completion polling, run the
RX modeset from a work element and only take the addr_list lock while
updating the RX mode address cache.

phys_port_name may be assembled by a helper in devlink. It is currently
the case only for mlxsw driver. Benefit from the get_devlink_port ndo
and call into devlink directly from dev_get_phys_port_name(). That saves

Currently if the driver registers devlink port instance, it should set
the devlink port attributes as well. Then the devlink core is able to
obtain physical port name itself, no need for driver to implement
the ndo. Once all drivers will implement devlink port registration,
this ndo should be removed. This warning guides new

My recent patch had at least three problems :
1) TX zerocopy wants notification when skb is acknowledged,
thus we need to call skb_zcopy_clear() if the skb is
cached into sk->sk_tx_skb_cache
2) Some applications might expect precise EPOLLOUT
notifications, so we need to update sk->sk_wmem_queued
and call sk_mem_uncharge() from sk_wmem_free_skb()
in all cases. The SOCK_QUEUE_SHRUNK flag must also be set.
3) Reuse of saved skb should have used skb_cloned() instead
of simply checking if the fast clone has been freed.

This patch adds a new action - 'check_pkt_len' which checks the
packet length and executes a set of actions if the packet
length is greater than the specified length or executes
another set of actions if the packet length is lesser or equal to.
This action takes below nlattrs
* OVS_CHECK_PKT_LEN_ATTR_PKT_LEN - 'pkt_len' to check for
* OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_GREATER - Nested actions
to apply if the packet length is greater than the specified 'pkt_len'
* OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_LESS_EQUAL - Nested
actions to apply if the packet length is lesser or equal to the
specified 'pkt_len'.
The main use case for adding this action is to solve the packet
drops because of MTU mismatch in OVN virtual networking solution.
When a VM (which belongs to a logical switch of OVN) sends a packet
destined to go via the gateway router and if the nic which provides
external connectivity, has a lesser MTU, OVS drops the packet
if the packet length is greater than this MTU.
With the help of this action, OVN will check the packet length
and if it is greater than the MTU size, it will generate an
ICMP packet (type 3, code 4) and includes the next hop mtu in it
so that the sender can fragment the packets.

An FoU socket is currently bound to the wildcard-address. While this
works fine, there are several use-cases where the use of the
wildcard-address is not desirable. For example, I use FoU on some
multi-homed servers and would like to use FoU on only one of the
interfaces.
This commit adds support for binding FoU sockets to a given source
address/interface, as well as connecting the socket to a given
destination address/port. udp_tunnel already provides the required
infrastructure, so most of the code added is for exposing and setting
the different attributes (local address, peer address, etc.).
The lookups performed when we add, delete or get an FoU-socket has also
been updated to compare all the attributes a user can set. Since the
comparison now involves several elements, I have added a separate
comparison-function instead of open-coding.
In order to test the code and ensure that the new comparison code works
correctly, I started by creating a wildcard socket bound to port 1234 on
my machine. I then tried to create a non-wildcarded socket bound to the
same port, as well as fetching and deleting the socket (including source
address, peer address or interface index in the netlink request). Both
the create, fetch and delete request failed. Deleting/fetching the
socket was only successful when my netlink request attributes matched
those used to create the socket.
I then repeated the tests, but with a socket bound to a local ip
address, a socket bound to a local address + interface, and a bound
socket that was also «connected» to a peer. Add only worked when no
socket with the matching source address/interface (or wildcard) existed,
while fetch/delete was only successful when all attributes matched.
In addition to testing that the new code work, I also checked that the
current behavior is kept. If none of the new attributes are provided,
then an FoU-socket is configured as before (i.e., wildcarded). If any
of the new attributes are provided, the FoU-socket is configured as
expected.
v1->v2:
* Fixed building with IPv6 disabled (kbuild).
* Fixed a return type warning and make the ugly comparison function more
readable (kbuild).
* Describe more in detail what has been tested (thanks David Miller).
* Make peer port required if peer address is specified.
