Ido Schimmel says: ==================== selftests: forwarding: Add VRF-based tests One of the nice things about network namespaces is that they allow one to easily create and test complex environments. Unfortunately, these namespaces can not be used with actual switching ASICs, as their ports can not be migrated to other network namespaces (NETIF_F_NETNS_LOCAL) and most of them probably do not support the L1-separation provided by namespaces. However, a similar kind of flexibility can be achieved by using VRFs and by looping the switch ports together. For example: br0 + vrf-h1 | vrf-h2 + +---+----+ + | | | | 192.0.2.1/24 + + + + 192.0.2.2/24 swp1 swp2 swp3 swp4 + + + + | | | | +--------+ +--------+ The VRFs act as lightweight namespaces representing hosts connected to the switch. This approach for testing switch ASICs has several advantages over the traditional method that requires multiple physical machines, to name a few: 1. Only the device under test (DUT) is being tested without noise from other system. 2. Ability to easily provision complex topologies. Testing bridging between 4-ports LAGs or 8-way ECMP requires many physical links that are not always available. With the VRF-based approach one merely needs to loopback more ports. These tests are written with switch ASICs in mind, but they can be run on any Linux box using veth pairs to emulate physical loopbacks. v2: * Order local variables declaration according to function arguments order (Petr) v1: * Change location to net/forwarding instead of forwarding/ * Add ability to pause on failure * Add ability to pause on cleanup * Make configuration file optional * Make ping/ping6/mz configurable * Add more tc tests ==================== Signed-off-by: -

This changeset moves ipvlan address under RCU protection, using a per ipvlan device spinlock to protect list mutation and RCU read access to protect list traversal. Also explicitly use RCU read lock to traverse the per port ipvlans list, so that we can now perform a full address lookup without asserting the RTNL lock. Overall this allows the ipvlan driver to check fully for duplicate addresses - before this commit ipv6 addresses assigned by autoconf via prefix delegation where accepted without any check - and avoid the following rntl assertion failure still in the same code path: RTNL: assertion failed at drivers/net/ipvlan/ipvlan_core.c (124) WARNING: CPU: 15 PID: 0 at drivers/net/ipvlan/ipvlan_core.c:124 ipvlan_addr_busy+0x97/0xa0 [ipvlan] Modules linked in: ipvlan(E) ixgbe CPU: 15 PID: 0 Comm: swapper/15 Tainted: G E 4.16.0-rc2.ipvlan+ #1782 Hardware name: Dell Inc.

Jiri Pirko says: ==================== mlxsw: Offload multi-queue RED support Nogah says: Support a two level hierarchy of offloaded qdiscs in mlxsw, with sch_prio being the root qdisc and sch_red as the children. +----------+ | sch_prio | +----+-----+ | | +----------------------------------+ | | | | | | | | | +---v---+ +----v---+ +-----v--+ |sch_red| |sch_red | |sch_red | +-------+ +--------+ +--------+ When setting sch_prio as the root qdisc on a physical port, mlxsw will offload it. When adding it with sch_red as a child qdisc, it will offload it as well. Relocating child qdisc or connecting them to more then one child will result in unoffloading them. Relocating child qdisc more then once is highly unrecommended and might cause a miss match between the kernel configuration and the offloaded one. The offloaded configuration will be aligned with the one shown in the show command. Changing the priomap parameter of sch_prio might cause a band that its configuration was changed and it has offloaded sch_red set on it, to lose some stats data as if sch_red was unoffloaded and offloaded again. However, it won't affect the data on this band that will have sch_red continuously. Patch 1 adds support for setting RED as the child of root qdisc. Patches 2-4 add support for RED bstasts for offloaded child qdiscs. Patches 5-6 handle backlog related changes for offloaded child qdiscs. Patches 7-8 update PRIO in mlxsw to be able to have RED as child on its bands. Patch 9 adds offload handles for PRIO graft operations. In mlxsw it will cause the driver to stop offloading the child in question. ==================== Signed-off-by: -

When the number the bands of sch_prio is decreased, child qdiscs on the deleted bands would get deleted as well. This change and deletions are being done under sch_tree_lock of the sch_prio qdisc. Part of the destruction of qdisc is unoffloading it, if it is offloaded. Un-offloading can't be done inside this lock. Move the offload command to be done before reducing the number of bands, so unoffloading of the qdiscs that are about to be deleted could be done outside of the lock. Signed-off-by:

When removing a child qdisc its backlog will be decreased from the parent backlog. The driver backlog count should do the same. When the parent changes its configuration, the child might need to clean its stats. However, the backlog can't be cleaned with the rest of the stats, because it reflects a momentary value that needs to be synced with the core, not the history of the qdisc. Signed-off-by:

Priority counters count packets according to their packet priority. Collect the stats for sch_red based on these counters, so the qdisc bstats will be the sum of counters matching the priorities marked in the qdisc priomap. Changing the mapping of the priorities to bands while traffic is running can result in losing the stats of the bands qdiscs from their last dump call to this change, as if the qdisc was unoffloaded and re-offloaded. It will not affect the traffic behaviour according to sch_red. Signed-off-by:

Marvell PPv2 controller allows for generic packet filtering. This commit adds entries to implement VLAN filtering. The approach taken is : - Filter entries that would match on the presence of the VLAN tag (existing VLAN detection, DSA / EDSA detection) will set the next lookup ID to be for the VID. - For each VLAN existing on a given port, we add an entry that matches this specific VID. If the incoming packet matches the VID entry, it is set for the next lookup in the chain (LU_L2). - A Guard entry is added for each port, that will match if the incoming packet didn't match any of the above VID entries. This entry tags the packet to be dropped. Due to this design, and the fact that the total 256 filter entries are also used for other purposes, we have a limit of 10 VLANs per port. To accommodate the case where we would need more VLANS on one port, this patch implements the ndo_set_features to allow for disabling of VLAN filtering using ethtool. The default config has VLAN filtering disabled. Signed-off-by:
