Saeed Mahameed says: ==================== mlx5-updates-2023-04-11 1) Vlad adds the support for linux bridge multicast offload support Patches #1 through #9 Synopsis Vlad Says: ============== Implement support of bridge multicast offload in mlx5. Handle port object attribute SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED notification to toggle multicast offload and bridge snooping support on bridge. Handle port object SWITCHDEV_OBJ_ID_PORT_MDB notification to attach a bridge port to MDB. Steering architecture Existing offload infrastructure relies on two levels of flow tables - bridge ingress and egress. For multicast offload the architecture is extended with additional layer of per-port multicast replication tables. Such tables filter loopback traffic (so packets are not replicated to their source port) and pop VLAN headers for "untagged" VLANs. The tables are referenced by the MDB rules in egress table. MDB egress rule can point to multiple per-port multicast tables, which causes matching multicast traffic to be replicated to all of them, and, consecutively, to several bridge ports: +--------+--+ +---------------------------------------> Port 1 | | | +-^------+--+ | | | | +-----------------------------------------+ | +---------------------------+ | | EGRESS table | | +--> PORT 1 multicast table | | +----------------------------------+ +-----------------------------------------+ | | +---------------------------+ | | INGRESS table | | | | | | | | +----------------------------------+ | dst_mac=P1,vlan=X -> pop vlan, goto P1 +--+ | | FG0: | | | | | dst_mac=P1,vlan=Y -> pop vlan, goto P1 | | | src_port=dst_port -> drop | | | src_mac=M1,vlan=X -> goto egress +---> dst_mac=P2,vlan=X -> pop vlan, goto P2 +--+ | | FG1: | | | ... | | dst_mac=P2,vlan=Y -> goto P2 | | | | VLAN X -> pop, goto port | | | | | dst_mac=MDB1,vlan=Y -> goto mcast P1,P2 +-----+ | ... | | +----------------------------------+ | | | | | VLAN Y -> pop, goto port +-------+ +-----------------------------------------+ | | | FG3: | | | | matchall -> goto port | | | | | | | +---------------------------+ | | | | | | +--------+--+ +---------------------------------------> Port 2 | | | +-^------+--+ | | | | | +---------------------------+ | +--> PORT 2 multicast table | | +---------------------------+ | | | | | FG0: | | | src_port=dst_port -> drop | | | FG1: | | | VLAN X -> pop, goto port | | | ... | | | | | | FG3: | | | matchall -> goto port +-------+ | | +---------------------------+ Patches overview: - Patch 1 adds hardware definition bits for capabilities required to replicate multicast packets to multiple per-port tables. These bits are used by following patches to only attempt multicast offload if firmware and hardware provide necessary support. - Pathces 2-4 patches are preparations and refactoring. - Patch 5 implements necessary infrastructure to toggle multicast offload via SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED port object attribute notification. This also enabled IGMP and MLD snooping. - Patch 6 implements per-port multicast replication tables. It only supports filtering of loopback packets. - Patch 7 extends per-port multicast tables with VLAN pop support for 'untagged' VLANs. - Patch 8 handles SWITCHDEV_OBJ_ID_PORT_MDB port object notifications. It creates MDB replication rules in egress table that can replicate packets to multiple per-port multicast tables. - Patch 9 adds tracepoints for MDB events. ============== 2) Parav Create a new allocation profile for SFs, to save on memory 3) Yevgeny provides some initial patches for upcoming software steering support new pattern/arguments type of modify_header actions. Starting with ConnectX-6 DX, we use a new design of modify_header FW object. The current modify_header object allows for having only limited number of these FW objects, which means that we are limited in the number of offloaded flows that require modify_header action. As a preparation Yevgeny provides the following 4 patches: - Patch 1: Add required mlx5_ifc HW bits - Patch 2, 3: Add new WQE type and opcode that is required for pattern/arg support and adds appropriate support in dr_send.c - Patch 4: Add ICM pool for modify-header-pattern objects and implement patterns cache, allowing patterns reuse for different flows * tag 'mlx5-updates-2023-04-11' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: DR, Add modify-header-pattern ICM pool net/mlx5: DR, Prepare sending new WQE type net/mlx5: Add new WQE for updating flow table net/mlx5: Add mlx5_ifc bits for modify header argument net/mlx5: DR, Set counter ID on the last STE for STEv1 TX net/mlx5: Create a new profile for SFs net/mlx5: Bridge, add tracepoints for multicast net/mlx5: Bridge, implement mdb offload net/mlx5: Bridge, support multicast VLAN pop net/mlx5: Bridge, add per-port multicast replication tables net/mlx5: Bridge, snoop igmp/mld packets net/mlx5: Bridge, extract code to lookup parent bridge of port net/mlx5: Bridge, move additional data structures to priv header net/mlx5: Bridge, increase bridge tables sizes net/mlx5: Add mlx5_ifc definitions for bridge multicast support ==================== Link: https://lore.kernel.org/r/20230412040752.14220-1-saeed@kernel.org Signed-off-by: Jakub Kicinski

net/mlx5e: Propagate an internal event in case uplink netdev changes

2023-02-09T04:40:57+00:00

Whenever uplink netdev is set/cleared, propagate newly introduced event to inform notifier blocks netdev was added/removed. Move the set() helper to core.c from header, introduce clear() and netdev_added_event_replay() helpers. The last one is going to be called from rdma driver, so export it.

net/mlx5: E-Switch, properly handle ingress tagged packets on VST

2022-12-28T19:38:49+00:00

Fix SRIOV VST mode behavior to insert cvlan when a guest tag is already present in the frame. Previous VST mode behavior was to drop packets or override existing tag, depending on the device version. In this patch we fix this behavior by correctly building the HW steering rule with a push vlan action, or for older devices we ask the FW to stack the vlan when a vlan is already present.
