ipmr and ip6mr utilize the exact same methods for searching the hashed resolved connections, difference being only in the construction of the hash comparison key. In order to unite the flow, introduce an mr_table operation set that would contain the protocol specific information required for common flows, in this case - the hash parameters and a comparison key representing a (*,*) route.

mfc_cache and mfc6_cache are almost identical - the main difference is in the origin/group addresses and comparison-key. Make a common structure encapsulating most of the multicast routing logic - mr_mfc and convert both ipmr and ip6mr into using it. For easy conversion [casting, in this case] mr_mfc has to be the first field inside every multicast routing abstraction utilizing it. Signed-off-by:

Now that both ipmr and ip6mr are using the same mr_table structure, we can have a common function to allocate & initialize a new instance. Signed-off-by:

Following previous changes to ip6mr, mr_table and mr6_table are basically the same [up to mr6_table having additional '6' suffixes to its variable names]. Move the common structure definition into a common header; This requires renaming all references in ip6mr to variables that had the distinct suffix. Signed-off-by:

Yuval Mintz authored
Since commit 8fb472c0 ("ipmr: improve hash scalability") ipmr has been using rhashtable as a basis for its mfc routes, but ip6mr is currently still using the old private MFC hash implementation. Align ip6mr to the current ipmr implementation. Signed-off-by:

In ipmr the mr_table socket is handled under RCU. Introduce the same for ip6mr. Signed-off-by:

Yuval Mintz authored
The two implementations have almost identical structures - vif_device and mif_device. As a step toward uniforming the mr_tables, eliminate the mif_device and relocate the vif_device definition into a new common header file. Also, introduce a common initializing function for setting most of the vif_device fields in a new common source file. This requires modifying the ipv{4,6] Kconfig and ipv4 makefile as we're introducing a new common config option - CONFIG_IP_MROUTE_COMMON. Signed-off-by: -

Roopa Prabhu says: ==================== fib_rules: support sport, dport and proto match This series extends fib rule match support to include sport, dport and ip proto match (to complete the 5-tuple match support). Common use-cases of Policy based routing in the data center require 5-tuple match. The last 2 patches in the series add a call to flow dissect in the fwd path if required by the installed fib rules (controlled by a flag). v1: - Fix errors reported by kbuild and feedback on RFC - extend port match uapi to accomodate port ranges v2: - address comments from Nikolay, David Ahern and Paolo (Thanks!) Pending things I will submit separate patches for: - extack for fib rules - fib rules test (as requested by david ahern) ==================== Signed-off-by: -

Dissect flow in fwd path if fib rules require it. Controlled by a flag to avoid penatly for the common case. Flag is set when fib rules with sport, dport and proto match that require flow dissect are installed. Also passes the dissected hash keys to the multipath hash function when applicable to avoid dissecting the flow again. icmp packets will continue to use inner header for hash calculations.

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: -

Offload sch_prio graft command for capable drivers. Warn in case of a failure, unless the graft was done as part of a destroy operation (the new qdisc is a noop) or if all the qdiscs (the parent, the old child, and the new one) are not offloaded. 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:

Offloaded qdiscs are allowed to expose only parts of their statistics. It means that if backlog is being exposed and qlen is not, it might trigger a warning in qdisc_tree_reduce_backlog. Do not warn in case the qdisc that was removed was an offloaded one. 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:
