2017-11-04mlxsw: spectrum_router: Handle down of tunnel underlayPetr Machata1-2/+55
When the bound device of a tunnel device is down, encapsulated packets are not egressed anymore, but tunnel decap still works. Extend mlxsw_sp_nexthop_rif_update() to take IFF_UP into consideration when deciding whether a given next hop should be offloaded. Because the new logic was added to mlxsw_sp_nexthop_rif_update(), this fixes the case where a newly-added tunnel has a down bound device, which would previously be fully offloaded. Now the down state of the bound device is noted and next hops forwarding to such tunnel are not offloaded. In addition to that, notice NETDEV_UP and NETDEV_DOWN of a bound device to force refresh of tunnel encap route offloads.

2017-11-04mlxsw: spectrum: Handle NETDEV_CHANGE on L3 tunnelsPetr Machata4-7/+114
Changes to L3 tunnel netdevices (through `ip tunnel change' as well as `ip link set') lead to NETDEV_CHANGE being generated on the tunnel device. Because what is relevant for the tunnel in question depends on the tunnel type, handling of the event is dispatched to the IPIP module through a newly-added interface mlxsw_sp_ipip_ops.ol_netdev_change(). IPIP tunnels now remember the last set of tunnel parameters in struct mlxsw_sp_ipip_entry.parms, and use it to figure out what exactly has changed.

2017-11-04mlxsw: spectrum: Support IPIP underlay VRF migrationPetr Machata3-0/+110
When a bound device of a tunnel netdevice changes VRF, the loopback RIF that backs the tunnel needs to be updated and existing encapsulating routes need to be refreshed. Note that several tunnels can share the same bound device, in which case all the impacted tunnels need to be updated.

2017-11-04mlxsw: spectrum_router: Onload conflicting tunnelsPetr Machata2-21/+60
The approach for offloading IP tunnels implemented currently by mlxsw doesn't allow two tunnels that have the same local IP address in the same (underlay) VRF. Previously, offloads were introduced on demand as encap routes were formed. When such a route was created that would cause offload of a conflicting tunnel, mlxsw_sp_ipip_entry_create() would detect it and return -EEXIST, which would propagate up and cause FIB abort. Now however IPIP entries are created as soon as an offloadable netdevice is created, and the failure prevents creation of such device. Furthermore, if the driver is installed at the point where such conflicting tunnels exist, the failure actually prevents successful modprobe. Furthermore, follow-up patches implement handling of NETDEV_CHANGE due to the local address change. However, NETDEV_CHANGE can't be vetoed. The failure merely means that the offloads weren't updated, but the change in Linux configuration is not rolled back. It is thus desirable to have a robust way of handling these conflicts, which can later be reused for handling NETDEV_CHANGE as well. To fix this, when a conflicting tunnel is created, instead of failing, simply pull the old tunnel to slow path and reject offloading the new one. Introduce two functions: mlxsw_sp_ipip_entry_demote_tunnel() and mlxsw_sp_ipip_demote_tunnel_by_saddr() to handle this. Make them both public, because they will be useful later on in this patchset.

2017-11-04mlxsw: spectrum_router: Fix saddr deduction in mlxsw_sp_ipip_entry_create()Petr Machata1-2/+2
When trying to determine whether there are other offloaded tunnels with the same local address, mlxsw_sp_ipip_entry_create() should look for a tunnel with matching UL protocol, matching saddr, in the same VRF. However instead of taking into account the UL protocol of the tunnel netdevice (which mlxsw_sp_ipip_entry_saddr_matches() then compares to the UL protocol of inspected IPIP entry), it deduces the UL protocol from the inspected IPIP entry (and that's compared to itself). This is currently immaterial, because only one tunnel type is offloaded, and therefore the UL protocol always matches, but introducing support for a tunnel with IPv6 underlay would uncover this error.

The work that needs to be done to update HW configuration in response to changes is similar to what __mlxsw_sp_ipip_entry_update_tunnel() already does, but with a number of twists: each change requires a different subset of things to happen.

2017-11-04mlxsw: spectrum: Propagate extack for tunnel eventsPetr Machata2-17/+23
The function mlxsw_sp_rif_create() takes an extack parameter. So far, for creation of loopback interfaces, NULL was passed. For some events however the extack can be extracted and passed along. So do that for NETDEV_CHANGEUPPER handler. Use the opportunity to update the type of info argument that mlxsw_sp_netdevice_ipip_ol_event() takes. Follow-up patches will introduce handling of more changes, and some of them carry an extack as well, but in an info structure of a different type. Though not strictly erroneous (the pointer could be cast whichever way), it makes no sense to pretend the value is always of a certain type, when in fact it isn't. So change the prototype of the above-mentioned function as well.

To implement NETDEV_CHANGE notifications on IP-in-IP tunnels, the handler needs to figure out what actually changed, to understand how exactly to update the offloads. It will do so by storing struct ip_tunnel_parm with previous configuration, and comparing that to the new version.

2017-11-03iwlwifi: mvm: improve latency when there is a reorder timeoutSara Sharon1-0/+16
When there is a reorder timeout, we may get to a situation where we have the timeout latency for all the next 64 frames. This happens since NSSN is behind for a while, and the driver won't release the frames, since it is not allowed by NSSN. As a result the frame is stored in the reorder buffer although there is no hole, and released 100 ms later. Add a direct comparison to the reorder buffer head, and release immediately if possible. For example: Frame 0 is missed. We receive frame 1, and store it in the buffer. After 100 ms, frame 1 is released and reorder buffer head is 2. We then receive frame 2, with NSSN 0, and store it instead of releasing it. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-11-03iwlwifi: mvm: rs: remove the ANT C from the toogle antenna logicEmmanuel Grumbach1-7/+3
We don't plan to have products with 3 antennas in the near future. All the rest of the code follows the same assumption as well. Remove the support for antenna C from rs_toggle_ant. When trying to toggle from ANT_B, this avoids to go through ANT_C, discover that it doesn't exist and continue to ANT_A. In MIMO, this avoids to do ANT_AB -> ANT_BC -> ANT_AC and back to ANT_AB.

2017-11-03iwlwifi: mvm: reset seq num after restartLiad Kaufman1-0/+8
After a FW reset on A000 NICs, the driver doesn't set the seq number when re-allocating the queues. This in turn leads to a mismatch between the seq number the driver thinks each frame has, and the actual seq num given by the HW. This especially causes issues with aggregations, since the driver could be waiting to start an aggregation and queue traffic from the mac80211 until then, when actually it shouldn't be waiting.

2017-11-03iwlwifi: mvm: cleanup references to aggregation count limitSara Sharon1-12/+12
Currently the code is mixing defines and is inconsistent. When enabling a queue, we usually configure the scheduler with IWL_FRAME_LIMIT - 64. When sending to firmware the rate scaling, we limit aggregation to LINK_QUAL_AGG_FRAME_LIMIT_DEF - 63, due to a scheduler bug. Given that, clean up the following: - Fix a stray queue enablement with LINK_QUAL_AGG_FRAME_LIMIT_DEF. - Change the comparison that tests if queue needs to be reconfigured to be compared directly to how it was configured. This also saves the redundant round down of the buffer size just for the sake of comparing it, making the code more readable. - Better document gen2 logic Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
