git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== This patch series contains various fixes, additions and improvements to mlx5 software steering. Patch 1: adds support for REMOVE_HEADER packet reformat - a new reformat type that is supported starting with ConnectX-6 DX, and allows removing an arbitrary size packet segment at a selected position. Patches 2 and 3: add support for VLAN pop on TX and VLAN push on RX flows. Patch 4: enables retransmission mechanism for the SW Steering RC QP. Patch 5: does some improvements to error flow in building STE array and adds a more informative printout of an invalid actions sequence. Patch 6: improves error flow on SW Steering QP error. Patch 7: reduces the log level of a message that is printed when a table is connected to a lower/same level destination table, as this case proves to be not as rare as it was in the past. Patch 8: adds missing support for matching on IPv6 flow label for devices older than ConnectX-6 DX. Patch 9: replaces uintN_t types with kernel-style types. Patch 10: allows for using the right API for updating flow tables - if it is a FW-owned table, then FW API will be used. Patch 11: adds support for 'ignore_flow_level' on multi-destination flow tables that are created by SW Steering. Patch 12: optimizes FDB RX steering rule by skipping matching on source port, as the source port for all incoming packets equals to wire. Patch 13: is a small code refactoring - it merges several DR_STE_SIZE enums into a single enum. Patch 14: does some additional refactoring and removes HW-specific STE type from NIC domain. Patch 15: removes rehash ctrl struct from dr_htbl struct and saves some memory. Patch 16: does a more significant improvement in terms of memory consumption and was able to save about 1.6 Gb for 8M rules. Patch 17: adds support for update FTE, which is needed for cases where there are multiple rules with the same match. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2021-08-26net/mlx5: DR, Improve rule tracking memory consumptionYevgeny Kliteynik
To track each STE of the rule a rule member was allocated, each member would point to one STE. This means that we would allocate 40B (rule member) * number of STEs per rule. To reduce this per rule allocation we use the STE tree pointers for next_htbl and pointing STE to navigate the tree, this allows us to keep only the pointer to the last STE of rule (always unique). From the last rule STE we are able to traverse and rebuild all of the STEs that construct the rule. In our testing with 8M rules, each consisting of 7 STES, we were able to reduce 1.6GB of memory.

2021-08-26net/mlx5: DR, fix a potential use-after-free bugWentao_Liang
In line 849 (#1), "mlx5dr_htbl_put(cur_htbl);" drops the reference to cur_htbl and may cause cur_htbl to be freed. However, cur_htbl is subsequently used in the next line, which may result in an use-after-free bug. Fix this by calling mlx5dr_err() before the cur_htbl is put.

2021-08-26net/mlx5e: Use correct eswitch for stack devices with lagDmytro Linkin
If link aggregation is used within stack devices driver rejects encap rules if PF of the VF tunnel device is down. This happens because route resolved for other PF and its eswitch instance is used to determine correct vport. To fix that use devcom feature to retrieve other eswitch instance if failed to find vport for the 1st eswitch and LAG is active.

When indirect forward group is created, flow is added with vhca id but without setting vhca id valid flag which violates the PRM. Fix by setting the missing flag, vhca id valid.

2021-08-26net/mlx5e: Fix possible use-after-free deleting fdb ruleRoi Dayan
After neigh-update-add failure we are still with a slow path rule but the driver always assume the rule is an fdb rule. Fix neigh-update-del by checking slow path tc flag on the flow. Also fix neigh-update-add for when neigh-update-del fails the same.
