Rename fib6_nh entries that will be moved to a fib_nh_common struct. Specifically, the device, gateway, flags, and lwtstate are common with all nexthop definitions. In some places new temporary variables are declared or local variables renamed to maintain line lengths. Rename only; no functional change intended.

Rename fib_nh entries that will be moved to a fib_nh_common struct. Specifically, the device, oif, gateway, flags, scope, lwtstate, nh_weight and nh_upper_bound are common with all nexthop definitions. In the process shorten fib_nh_lwtstate to fib_nh_lws to avoid really long lines. Rename only; no functional change intended. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.

rt6_add_nexthop and rt6_nexthop_info only need the fib6_info for the gateway flag and the nexthop weight, and the presence of a gateway is now per-nexthop. Update the signatures to take a fib6_nh and nexthop weight and better align with the ipv4 versions.

fib6_ignore_linkdown takes a fib6_info but only looks at the net_device and its IPv6 config. Change it to take a net_device over a fib6_info as its input argument. In addition, move it to a header file to make the check inline and usable later with IPv4 code without going through the ipv6 stub, and rename to ip6_ignore_linkdown since it is only checking the setting based on the ipv6 struct on a device.

The gateway setting is not per fib6_info entry but per-fib6_nh. Add a new fib_nh_has_gw flag to fib6_nh and convert references to RTF_GATEWAY to the new flag. For IPv6 address the flag is cheaper than checking that nh_gw is non-0 like IPv4 does. While this increases fib6_nh by 8-bytes, the effective allocation size of a fib6_info is unchanged. The 8 bytes is recovered later with a fib_nh_common change. Signed-off-by: David Ahern <dsahern@gmail.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.

Similar to IPv4, consolidate the fib6_nh initialization into a helper. As a new standalone function, add a cleanup path to put lwtstate on error. To avoid modifying fib6_config flags, move the reject check to a helper that is invoked once by fib6_nh_init to reset the device and then again in ip6_route_info_create to set the fib6_flags.

Ido Schimmel says: ==================== selftests: forwarding: Add new test cases This patchset mainly adds new forwarding test cases and performs small changes in existing infrastructure. Patches #1-#3 add new test cases for multicast RPF check, PCP and VLAN matching using flower and tc VLAN modify action. The rest of the patches are from Petr who says: In patches #4 and #5, devlink_lib.sh is fixed to first not cause double inclusion of lib.sh, and then to deduce the device name in a simpler way. In patch #6, helpers for dealing with shared buffer configuration are added to devlink_lib.sh. In patch #7, MC-awareness test is fixed to configure shared buffers explicitly. In patch #8, several helpers are extracted from the MC-awareness test and put into a new mlxsw-specific library, qos_lib.sh. In patch #9, a new test is added which checks configuration of strictly-prioritized streams. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This test runs two streams of traffic from two independent ports to create congestion on one egress port. It is necessary to configure the shared buffer thresholds correctly, to make sure that there is traffic from both streams in the shared buffer. Only then can the test actually test prioritization among these streams. Without this configuration, it is possible, that one of the streams takes all of port-pool quota, and the other stream is not even admitted, thus invalidating the result. On Spectrum-1, this is not a problem, because MC traffic uses a separate pool. But for Spectrum-2, MC and UC share the same pool, and the correct configuration is important.

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.

If no timeout is specified, it acts as is, that is the default timeout for the connection will be automatically applied.

This patch exports nf_ct_set_timeout() and nf_ct_destroy_timeout(). The two functions are derived from xt_ct_destroy_timeout() and xt_ct_set_timeout() in xt_CT.c, and moved to nf_conntrack_timeout.c without any functional change. It would be useful for other users (i.e. OVS) that utilizes the finer-grain conntrack timeout feature.

Julian Wiedmann says: ==================== 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.

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.

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 sort of default callback for all cmds. But in practice, it is only used for half of the cmd buffers we issue. Reduce the confusion by only setting this callback for cmds that actually want it, and while at it give the callback a name that matches the established naming scheme.

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.

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().

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.
