Non-linear legacy RQ: validate MTU for robustness, build the linear part of SKB over the first hardware fragment (instead of copying the packet headers), adjust headroom calculations to allow enabling headroom in the non-linear mode (useful for XDP multi buffer). b. XDP: do the XDP program test before function call, optimize parameters of mlx5e_xdp_handle. 2) From Rongwei Liu, DR, reduce steering memory usage Currently, mlx5 driver uses mlx5_htbl/chunk/ste to organize steering logic. However there is a little memory waste. This update targets to reduce steering memory footprint by: a. Adjust struct member layout. b. Remove duplicated indicator by using simple functions call. With 500k TX rules(3 ste) plus 500k RX rules(6 stes), these patches can save around 17% memory. 3) Three cleanup commits at the end of this series. =================== Signed-off-by: David S.

Per-flow mirroring with the VCAP IS2 TCAM (in itself handled as an offload for tc-flower) is done by setting the MIRROR_ENA bit from the action vector of the filter. The packet is mirrored to the port mask configured in the ANA:ANA:MIRRORPORTS register (the same port mask as the destinations for port-based mirroring). Functionality was tested with: tc qdisc add dev swp3 clsact tc filter add dev swp3 ingress protocol ip \ flower skip_sw ip_proto icmp \ action mirred egress mirror dev swp1 and pinging through swp3, while seeing that the ICMP replies are mirrored towards swp1.

2022-03-18net: mscc: ocelot: establish functions for handling VCAP aux resourcesVladimir Oltean1-11/+30
Some VCAP filters utilize resources which are global to the switch, like for example VCAP IS2 policers take an index into a global policer pool. In commit c9a7fe1238e5 ("net: mscc: ocelot: add action of police on vcap_is2"), Xiaoliang expressed this by hooking into the low-level ocelot_vcap_filter_add_to_block() and ocelot_vcap_block_remove_filter() functions, and allocating/freeing the policers from there. Evaluating the code, there probably isn't a better place, but we'll need to do something similar for the mirror ports, and the code will start to look even more hacked up than it is right now. Create two ocelot_vcap_filter_{add,del}_aux_resources() functions to contain the madness, and pollute less the body of other functions such as ocelot_vcap_filter_add_to_block().

2022-03-18net: mscc: ocelot: add port mirroring support using tc-matchallVladimir Oltean4-2/+159
Ocelot switches perform port-based ingress mirroring if ANA:PORT:PORT_CFG field SRC_MIRROR_ENA is set, and egress mirroring if the port is in ANA:ANA:EMIRRORPORTS. Both ingress-mirrored and egress-mirrored frames are copied to the port mask from ANA:ANA:MIRRORPORTS. So the choice of limiting to a single mirror port via ocelot_mirror_get() and ocelot_mirror_put() may seem bizarre, but the hardware model doesn't map very well to the user space model. If the user wants to mirror the ingress of swp1 towards swp2 and the ingress of swp3 towards swp4, we'd have to program ANA:ANA:MIRRORPORTS with BIT(2) | BIT(4), and that would make swp1 be mirrored towards swp4 too, and swp3 towards swp2. But there are no tc-matchall rules to describe those actions. Now, we could offload a matchall rule with multiple mirred actions, one per desired mirror port, and force the user to stick to the multi-action rule format for subsequent matchall filters. But both DSA and ocelot have the flow_offload_has_one_action() check for the matchall offload, plus the fact that it will get cumbersome to cross-check matchall mirrors with flower mirrors (which will be added in the next patch). As a result, we limit the configuration to a single mirror port, with the possibility of lifting the restriction in the future. Frames injected from the CPU don't get egress-mirrored, since they are sent with the BYPASS bit in the injection frame header, and this bypasses the analyzer module (effectively also the mirroring logic). I don't know what to do/say about this. Functionality was tested with: tc qdisc add dev swp3 clsact tc filter add dev swp3 ingress \ matchall skip_sw \ action mirred egress mirror dev swp1 and pinging through swp3, while seeing that the ICMP replies are mirrored towards swp1.

2022-03-18Merge branch 'net-bridge-multiple-spanning-trees'Jakub Kicinski23-152/+1381
Tobias Waldekranz says: ==================== net: bridge: Multiple Spanning Trees The bridge has had per-VLAN STP support for a while now, since: https://lore.kernel.org/netdev/20200124114022.10883-1-nikolay@cumulusnetworks.com/ The current implementation has some problems: - The mapping from VLAN to STP state is fixed as 1:1, i.e. each VLAN is managed independently. This is awkward from an MSTP (802.1Q-2018, Clause 13.5) point of view, where the model is that multiple VLANs are grouped into MST instances. Because of the way that the standard is written, presumably, this is also reflected in hardware implementations. It is not uncommon for a switch to support the full 4k range of VIDs, but that the pool of MST instances is much smaller. Some examples: Marvell LinkStreet (mv88e6xxx): 4k VLANs, but only 64 MSTIs Marvell Prestera: 4k VLANs, but only 128 MSTIs Microchip SparX-5i: 4k VLANs, but only 128 MSTIs - By default, the feature is enabled, and there is no way to disable it. This makes it hard to add offloading in a backwards compatible way, since any underlying switchdevs have no way to refuse the function if the hardware does not support it - The port-global STP state has precedence over per-VLAN states. In MSTP, as far as I understand it, all VLANs will use the common spanning tree (CST) by default - through traffic engineering you can then optimize your network to group subsets of VLANs to use different trees (MSTI). To my understanding, the way this is typically managed in silicon is roughly: Incoming packet: .----.----.--------------.----.------------- | DA | SA | 802.1Q VID=X | ET | Payload ... '----'----'--------------'----'------------- | '->|\ .----------------------------. | +--> | VID | Members | ... | MSTI | PVID -->|/ |-----|---------|-----|------| | 1 | 0001001 | ... | 0 | | 2 | 0001010 | ... | 10 | | 3 | 0001100 | ... | 10 | '----------------------------' | .-----------------------------' | .------------------------. '->| MSTI | Fwding | Lrning | |------|--------|--------| | 0 | 111110 | 111110 | | 10 | 110111 | 110111 | '------------------------' What this is trying to show is that the STP state (whether MSTP is used, or ye olde STP) is always accessed via the VLAN table. If STP is running, all MSTI pointers in that table will reference the same index in the STP stable - if MSTP is running, some VLANs may point to other trees (like in this example). The fact that in the Linux bridge, the global state (think: index 0 in most hardware implementations) is supposed to override the per-VLAN state, is very awkward to offload. In effect, this means that when the global state changes to blocking, drivers will have to iterate over all MSTIs in use, and alter them all to match. This also means that you have to cache whether the hardware state is currently tracking the global state or the per-VLAN state. In the first case, you also have to cache the per-VLAN state so that you can restore it if the global state transitions back to forwarding. This series adds a new mst_enable bridge setting (as suggested by Nik) that can only be changed when no VLANs are configured on the bridge. Enabling this mode has the following effect: - The port-global STP state is used to represent the CST (Common Spanning Tree) (1/15) - Ingress STP filtering is deferred until the frame's VLAN has been resolved (1/15) - The preexisting per-VLAN states can no longer be controlled directly (1/15). They are instead placed under the MST module's control, which is managed using a new netlink interface (described in 3/15) - VLANs can br mapped to MSTIs in an arbitrary M:N fashion, using a new global VLAN option (2/15) Switchdev notifications are added so that a driver can track: - MST enabled state - VID to MSTI mappings - MST port states An offloading implementation is this provided for mv88e6xxx. ==================== Link: https://lore.kernel.org/r/20220316150857.2442916-1-tobias@waldekranz.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-03-18net: dsa: mv88e6xxx: Disentangle STU from VTUTobias Waldekranz4-135/+264
In early LinkStreet silicon (e.g. 6095/6185), the per-VLAN STP states were kept in the VTU - there was no concept of a SID. Later, the information was split into two tables, where the VTU only tracked memberships and deferred the STP state tracking to the STU via a pointer (SID). This meant that a group of VLANs could share the same STU entry. Most likely, this was done to align with MSTP (802.1Q-2018, Clause 13), which is built on this principle. While the VTU is still 4k lines on most devices, the STU is capped at 64 entries. This means that the current stategy, updating STU info whenever a VTU entry is updated, can not easily support MSTP because: - The maximum number of VIDs would also be capped at 64, as we would have to allocate one SID for every VTU entry - even if many VLANs would effectively share the same MST. - MSTP updates would be unnecessarily slow as you would have to iterate over all VLANs that share the same MST. In order to support MSTP offloading in the future, manage the STU as a separate entity from the VTU. Only add support for newer hardware with separate VTU and STU. VTU-only devices can also be supported, but essentially this requires a software implementation of an STU (fanning out state changed to all VLANs tied to the same MST).

Allow the user to switch from the current per-VLAN STP mode to an MST mode. Up to this point, per-VLAN STP states where always isolated from each other. This is in contrast to the MSTP standard (802.1Q-2018, Clause 13.5), where VLANs are grouped into MST instances (MSTIs), and the state is managed on a per-MSTI level, rather that at the per-VLAN level. Perhaps due to the prevalence of the standard, many switching ASICs are built after the same model. Therefore, add a corresponding MST mode to the bridge, which we can later add offloading support for in a straight-forward way. For now, all VLANs are fixed to MSTI 0, also called the Common Spanning Tree (CST). That is, all VLANs will follow the port-global state. Upcoming changes will make this actually useful by allowing VLANs to be mapped to arbitrary MSTIs and allow individual MSTI states to be changed.

2022-03-17net/mlx5: CT: Remove extra rhashtable remove on tuple entriesPaul Blakey1-1/+0
On tuple offload del command, tuples are tried to be removed twice from the hashtable, once directly via mlx5_tc_ct_entry_remove_from_tuples() and a second time in the following mlx5_tc_ct_entry_put()-> mlx5_tc_ct_entry_del()->mlx5_tc_ct_entry_remove_from_tuples() call. This doesn't cause any issue since rhashtable first checks if the removed object exists in the hashtable. Remove the extra mlx5_tc_ct_entry_remove_from_tuples().

Target to reduce the memory consumption in large scale of flow rules. They can be calculated quickly from buddy memory pool. 1. num_of_entries calls dr_icm_pool_get_chunk_num_of_entries(). 2. byte_size calls dr_icm_pool_get_chunk_byte_size(). Use chunk size in dr_icm_chunk to speed up and the one in dr_ste_htbl will be removed in the upcoming commit. This commit reduce 8 bytes from struct mlx5_dr_icm_chunk and its current size is 56 bytes.
