Line card can contain one or more devices that makes sense to make visible to the user. For example, this can be a gearbox with flash memory, which could be updated. Provide the driver possibility to attach such devices to a line card and expose those to user. Example: $ devlink lc show pci/0000:01:00.0 lc 8 pci/0000:01:00.0: lc 8 state active type 16x100G supported_types: 16x100G devices: device 0 device 1 device 2 device 3 Signed-off-by:

Vladimir Oltean says: ==================== DSA selftests When working on complex new features or reworks it becomes increasingly difficult to ensure there aren't regressions being introduced, and therefore it would be nice if we could go over the functionality we already have and write some tests for it. Verbally I know from Tobias Waldekranz that he has been working on some selftests for DSA, yet I have never seen them, so here I am adding some tests I have written which have been useful for me. The list is by no means complete (it only covers elementary functionality), but it's still good to have as a starting point. I also borrowed some refactoring changes from Joachim Wiberg that he submitted for his "net: bridge: forwarding of unknown IPv4/IPv6/MAC BUM traffic" series, but not the entirety of his selftests. I now think that his selftests have some overlap with bridge_vlan_unaware.sh and bridge_vlan_aware.sh and they should be more tightly integrated with each other - yet I didn't do that either :). Another issue I had with his selftests was that they jumped straight ahead to configure brport flags on br0 (a radical new idea still at RFC status) while we have bigger problems, and we don't have nearly enough coverage for the *existing* functionality. One idea introduced here which I haven't seen before is the symlinking of relevant forwarding selftests to the selftests/drivers/net/<my-driver>/ folder, plus a forwarding.config file. I think there's some value in having things structured this way, since the forwarding dir has so many selftests that aren't relevant to DSA that it is a bit difficult to find the ones that are. While searching for applications that I could use for multicast testing (not my domain of interest/knowledge really), I found Joachim Wiberg's mtools, mcjoin and omping, and I tried them all with various degrees of success. In particular, I was going to use mcjoin, but I faced some issues getting IPv6 multicast traffic to work in a VRF, and I bothered David Ahern about it here: https://lore.kernel.org/netdev/97eaffb8-2125-834e-641f-c99c097b6ee2@gmail.com/t/ It seems that the problem is that this application should use SO_BINDTODEVICE, yet it doesn't. So I ended up patching the bare-bones mtools (msend, mreceive) forked by Joachim from the University of Virginia's Multimedia Networks Group to include IPv6 support, and to use SO_BINDTODEVICE. This is what I'm using now for IPv6. Note that mausezahn doesn't appear to do a particularly good job of supporting IPv6 really, and I needed a program to emit the actual IP_ADD_MEMBERSHIP calls, for dev_mc_add(), so I could test RX filtering. Crafting the IGMP/MLD reports by hand doesn't really do the trick. While extremely bare-bones, the mreceive application now seems to do what I need it to. Feedback appreciated, it is very likely that I could have done things in a better way. ==================== Signed-off-by:

This adds an initial subset of forwarding selftests which I considered to be relevant for DSA drivers, along with a forwarding.config that makes it easier to run them (disables veth pair creation, makes sure MAC addresses are unique and stable). The intention is to request driver writers to run these selftests during review and make sure that the tests pass, or at least that the problems are known. Signed-off-by:

This tests the capability of switch ports to filter out undesired traffic. Different drivers are expected to have different capabilities here (so some may fail and some may pass), yet the test still has some value, for example to check for regressions. There are 2 kinds of failures, one is when a packet which should have been accepted isn't (and that should be fixed), and the other "failure" (as reported by the test) is when a packet could have been filtered out (for being unnecessary) yet it was received. The bridge driver fares particularly badly at this test: TEST: br0: Unicast IPv4 to primary MAC address [ OK ] TEST: br0: Unicast IPv4 to macvlan MAC address [ OK ] TEST: br0: Unicast IPv4 to unknown MAC address [FAIL] reception succeeded, but should have failed TEST: br0: Unicast IPv4 to unknown MAC address, promisc [ OK ] TEST: br0: Unicast IPv4 to unknown MAC address, allmulti [FAIL] reception succeeded, but should have failed TEST: br0: Multicast IPv4 to joined group [ OK ] TEST: br0: Multicast IPv4 to unknown group [FAIL] reception succeeded, but should have failed TEST: br0: Multicast IPv4 to unknown group, promisc [ OK ] TEST: br0: Multicast IPv4 to unknown group, allmulti [ OK ] TEST: br0: Multicast IPv6 to joined group [ OK ] TEST: br0: Multicast IPv6 to unknown group [FAIL] reception succeeded, but should have failed TEST: br0: Multicast IPv6 to unknown group, promisc [ OK ] TEST: br0: Multicast IPv6 to unknown group, allmulti [ OK ] mainly because it does not implement IFF_UNICAST_FLT. Yet I still think having the test (with the failures) is useful in case somebody wants to tackle that problem in the future, to make an easy before-and-after comparison. Signed-off-by: -

Bombard a standalone switch port with various kinds of traffic to ensure it is really standalone and doesn't leak packets to other switch ports. Also check for switch ports in different bridges, and switch ports in a VLAN-aware bridge but having different pvids. No forwarding should take place in either case. Signed-off-by:

Pinging an IPv6 link-local multicast address selects the link-local unicast address of the interface as source, and we'd like to monitor for that in tcpdump. Add a helper to the forwarding library which retrieves the link-local IPv6 address of an interface, to make that task easier. Signed-off-by:

Extend the forwarding library with calls to some small C programs which join an IP multicast group and send some packets to it. Both IPv4 and IPv6 groups are supported. Use cases range from testing IGMP/MLD snooping, to RX filtering, to multicast routing. Testing multicast traffic using msend/mreceive is intended to be done using tcpdump. Signed-off-by:

Extend tcpdump_start() & C:o to handle multiple instances. Useful when observing bridge operation, e.g., unicast learning/flooding, and any case of multicast distribution (to these ports but not that one ...). This means the interface argument is now a mandatory argument to all tcpdump_*() functions, hence the changes to the ocelot flower test. Signed-off-by:

By default, DSA switch ports inherit their MAC address from the DSA master. This works well for practical situations, but some selftests like bridge_vlan_unaware.sh loop back 2 standalone DSA ports with 2 bridged DSA ports, and require the bridge to forward packets between the standalone ports. Due to the bridge seeing that the MAC DA it needs to forward is present as a local FDB entry (it coincides with the MAC address of the bridge ports), the test packets are not forwarded, but terminated locally on br0. In turn, this makes the ping and ping6 tests fail. Address this by introducing an option to have stable MAC addresses. When mac_addr_prepare is called, the current addresses of the netifs are saved and replaced with 00:01:02:03:04:${netif number}. Then when mac_addr_restore is called at the end of the test, the original MAC addresses are restored. This ensures that the MAC addresses are unique, which makes the test pass even for DSA ports. The usage model is for the behavior to be opt-in via STABLE_MAC_ADDRS, which DSA should set to true, all others behave as before. By hooking the calls to mac_addr_prepare and mac_addr_restore within the forwarding lib itself, we do not need to patch each individual selftest, the only requirement is that pre_cleanup is called.

Mat Martineau says: ==================== mptcp: TCP fallback for established connections RFC 8684 allows some MPTCP connections to fall back to regular TCP when the MPTCP DSS checksum detects middlebox interference, there is only a single subflow, and there is no unacknowledged out-of-sequence data. When this condition is detected, the stack sends a MPTCP DSS option with an "infinite mapping" to signal that a fallback is happening, and the peers will stop sending MPTCP options in their TCP headers. The Linux MPTCP stack has not yet supported this type of fallback, instead closing the connection when the MPTCP checksum fails. This series adds support for fallback to regular TCP in a more limited scenario, for only MPTCP connections that have never connected additional subflows or transmitted out-of-sequence data. The selftests are also updated to check new MIBs that track infinite mappings. ==================== Signed-off-by: -

This patch adds the infinite mapping sending logic. Add a new flag send_infinite_map in struct mptcp_subflow_context. Set it true when a single contiguous subflow is in use and the allow_infinite_fallback flag is true in mptcp_pm_mp_fail_received(). In mptcp_sendmsg_frag(), if this flag is true, call the new function mptcp_update_infinite_map() to set the infinite mapping. Add a new flag infinite_map in struct mptcp_ext, set it true in mptcp_update_infinite_map(), and check this flag in a new helper mptcp_check_infinite_map(). In mptcp_update_infinite_map(), set data_len to 0, and clear the send_infinite_map flag, then do fallback. In mptcp_established_options(), use the helper mptcp_check_infinite_map() to let the infinite mapping DSS can be sent out in the fallback mode. Suggested-by:

When a bad checksum is detected and a single subflow is in use, don't send RST + MP_FAIL, send data_ack + MP_FAIL instead. So invoke tcp_send_active_reset() only when mptcp_has_another_subflow() is true. Signed-off-by:
