2020-03-20net/mlx5e: Fix hairpin RSS table sizeEli Cohen
commit 6412bb396a63f28de994b1480edf8e4caf4aa494 upstream. Set hairpin table size to the corret size, based on the groups that would be created in it. Groups are laid out on the table such that a group occupies a range of entries in the table. This implies that the group ranges should have correspondence to the table they are laid upon. The patch cited below made group 1's size to grow hence causing overflow of group range laid on the table.

2020-01-31net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookupSabrina Dubroca
commit 6c8991f41546c3c472503dff1ea9daaddf9331c2 upstream. ipv6_stub uses the ip6_dst_lookup function to allow other modules to perform IPv6 lookups. However, this function skips the XFRM layer entirely. All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the ip_route_output_key and ip_route_output helpers) for their IPv4 lookups, which calls xfrm_lookup_route(). This patch fixes this inconsistent behavior by switching the stub to ip6_dst_lookup_flow, which also calls xfrm_lookup_route(). This requires some changes in all the callers, as these two functions take different arguments and have different return types.

commit 73e6551699a32fac703ceea09214d6580edcf2d5 upstream.

2020-01-09net/mlx5e: Do not use non-EXT link modes in EXT modeEran Ben Elisha
commit 24960574505c49b102ca1dfa6bf109669bca2a66 upstream. On some old Firmwares, connector type value was not supported, and value read from FW was 0. For those, driver used link mode in order to set connector type in link_ksetting. After FW exposed the connector type, driver translated the value to ethtool definitions. However, as 0 is a valid value, before returning PORT_OTHER, driver run the check of link mode in order to maintain backward compatibility. Cited patch added support to EXT mode. With both features (connector type and EXT link modes) ,if connector_type read from FW is 0 and EXT mode is set, driver mistakenly compare EXT link modes to non-EXT link mode. Fixed that by skipping this comparison if we are in EXT mode, as connector type value is valid in this scenario.

2019-12-16net/mlx5e: Fix handling of compressed CQEs in case of low NAPI budgetMaxim Mikityanskiy
commit 9df86bdb6746d7fcfc2fda715f7a7c3d0ddb2654 upstream. When CQE compression is enabled, compressed CQEs use the following structure: a title is followed by one or many blocks, each containing 8 mini CQEs (except the last, which may contain fewer mini CQEs). Due to NAPI budget restriction, a complete structure is not always parsed in one NAPI run, and some blocks with mini CQEs may be deferred to the next NAPI poll call - we have the mlx5e_decompress_cqes_cont call in the beginning of mlx5e_poll_rx_cq. However, if the budget is extremely low, some blocks may be left even after that, but the code that follows the mlx5e_decompress_cqes_cont call doesn't check it and assumes that a new CQE begins, which may not be the case. In such cases, random memory corruptions occur. An extremely low NAPI budget of 8 is used when busy_poll or busy_read is active. This commit adds a check to make sure that the previous compressed CQE has been completely parsed after mlx5e_decompress_cqes_cont, otherwise it prevents a new CQE from being fetched in the middle of a compressed CQE. This commit fixes random crashes in __build_skb, __page_pool_put_page and other not-related-directly places, that used to happen when both CQE compression and busy_poll/busy_read were enabled.

[ Upstream commit 90bb769291161cf25a818d69cf608c181654473e ] This patch prevents a race between user invoked cached counters query and a neighbor last usage updater. The cached flow counter stats can be queried by calling "mlx5_fc_query_cached" which provides the number of bytes and packets that passed via this flow since the last time this counter was queried. It does so by reducting the last saved stats from the current, cached stats and then updating the last saved stats with the cached stats. It also provide the lastuse value for that flow. Since "mlx5e_tc_update_neigh_used_value" needs to retrieve the last usage time of encapsulation flows, it calls the flow counter query method periodically and async to user queries of the flow counter using cls_flower. This call is causing the driver to update the last reported bytes and packets from the cache and therefore, future user queries of the flow stats will return lower than expected number for bytes and packets since the last saved stats in the driver was updated async to the last saved stats in cls_flower. This causes wrong stats presentation of encapsulation flows to user. Since the neighbor usage updater only needs the lastuse stats from the cached counter, the fix is to use a dedicated lastuse query call that returns the lastuse value without synching between the cached stats and the last saved stats.

2019-06-07net/mlx5e: Replace reciprocal_scale in TX select queue functionShay Agroskin
The TX queue index returned by the fallback function ranges between [0,NUM CHANNELS - 1] if QoS isn't set and [0, (NUM CHANNELS)*(NUM TCs) -1] otherwise. Our HW uses different TC mapping than the fallback function (which is denoted as 'up', user priority) so we only need to extract a channel number out of the returned value. Since (NUM CHANNELS)*(NUM TCs) is a relatively small number, using reciprocal scale almost always returns zero. We instead access the 'txq2sq' table to extract the sq (and with it the channel number) associated with the tx queue, thus getting a more evenly distributed channel number. Perf: Rx/Tx side with Intel(R) Xeon(R) Silver 4108 CPU @ 1.80GHz and ConnectX-5. Used 'iperf' UDP traffic, 10 threads, and priority 5. Before: 0.566Mpps After: 2.37Mpps As expected, releasing the existing bottleneck of steering all traffic to TX queue zero significantly improves transmission rates.

2019-05-28net/mlx5e: Disable rxhash when CQE compress is enabledSaeed Mahameed
When CQE compression is enabled (Multi-host systems), compressed CQEs might arrive to the driver rx, compressed CQEs don't have a valid hash offload and the driver already reports a hash value of 0 and invalid hash type on the skb for compressed CQEs, but this is not good enough. On a congested PCIe, where CQE compression will kick in aggressively, gro will deliver lots of out of order packets due to the invalid hash and this might cause a serious performance drop. The only valid solution, is to disable rxhash offload at all when CQE compression is favorable (Multi-host systems).
