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:Jiri Pirko <jiri@nvidia.com> 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:

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: -

Guillaume Nault says: ==================== ipv4: First steps toward removing RTO_ONLINK RTO_ONLINK is a flag that allows to reduce the scope of route lookups. It's stored in a normally unused bit of the ->flowi4_tos field, in struct flowi4. However it has several problems: * This bit is also used by ECN. Although ECN bits are supposed to be cleared before doing a route lookup, it happened that some code paths didn't properly sanitise their ->flowi4_tos. So this mechanism is fragile and we had bugs in the past where ECN bits slipped in and could end up being erroneously interpreted as RTO_ONLINK. * A dscp_t type was recently introduced to ensure ECN bits are cleared during route lookups. ->flowi4_tos is the most important structure field to convert, but RTO_ONLINK prevents such conversion, as dscp_t mandates that ECN bits (where RTO_ONLINK is stored) be zero. Therefore we need to stop using RTO_ONLINK altogether. Fortunately RTO_ONLINK isn't a necessity. Instead of passing a flag in ->flowi4_tos to tell the route lookup function to restrict the scope, we can simply initialise the scope correctly. Patch 1 does some preparatory work: it stops resetting ->flowi4_scope automatically before a route lookup, thus allowing callers to set their desired scope without having to rely on the RTO_ONLINK flag. Patch 2-3 convert a few code paths to avoid relying on RTO_ONLINK. More conversions will have to take place before we can eventually remove this flag. ==================== Signed-off-by: -

All the *_redirect() and *_update_pmtu() functions initialise their struct flowi4 variable with either __build_flow_key() or build_sk_flow_key(). When sk is provided, these functions use RT_CONN_FLAGS() to set ->flowi4_tos and always use RT_SCOPE_UNIVERSE for ->flowi4_scope. Then they rely on ip_rt_fix_tos() to adjust the scope based on the RTO_ONLINK bit and to mask the tos with IPTOS_RT_MASK. This patch modifies __build_flow_key() and build_sk_flow_key() to properly initialise ->flowi4_tos and ->flowi4_scope, so that the ICMP redirects and PMTU handlers don't need an extra call to ip_rt_fix_tos() before doing a fib lookup. That is, we: * Drop RT_CONN_FLAGS(): use ip_sock_rt_tos() and ip_sock_rt_scope() instead, so that we don't have to rely on ip_rt_fix_tos() to adjust the scope anymore. * Apply IPTOS_RT_MASK to the tos, so that we don't need ip_rt_fix_tos() to do it for us. * Drop the ip_rt_fix_tos() calls that now become useless. The only remaining ip_rt_fix_tos() caller is ip_route_output_key_hash() which needs it as long as external callers still use the RTO_ONLINK flag. Note: This patch also drops some useless RT_TOS() calls as IPTOS_RT_MASK is a stronger mask. Signed-off-by:David Ahern <dsahern@kernel.org> Signed-off-by:

Now that ip_rt_fix_tos() doesn't reset ->flowi4_scope unconditionally, we don't have to rely on the RTO_ONLINK bit to properly set the scope of a flowi4 structure. We can just set ->flowi4_scope explicitly and avoid using RTO_ONLINK in ->flowi4_tos. This patch converts callers of ip_route_connect(). Instead of setting the tos parameter with RT_CONN_FLAGS(sk), as all callers do, we can: 1- Drop the tos parameter from ip_route_connect(): its value was entirely based on sk, which is also passed as parameter. 2- Set ->flowi4_scope depending on the SOCK_LOCALROUTE socket option instead of always initialising it with RT_SCOPE_UNIVERSE (let's define ip_sock_rt_scope() for this purpose). 3- Avoid overloading ->flowi4_tos with RTO_ONLINK: since the scope is now properly initialised, we don't need to tell ip_rt_fix_tos() to adjust ->flowi4_scope for us. So let's define ip_sock_rt_tos(), which is the same as RT_CONN_FLAGS() but without the RTO_ONLINK bit overload. Note: In the original ip_route_connect() code, __ip_route_output_key() might clear the RTO_ONLINK bit of fl4->flowi4_tos (because of ip_rt_fix_tos()). Therefore flowi4_update_output() had to reuse the original tos variable. Now that we don't set RTO_ONLINK any more, this is not a problem and we can use fl4->flowi4_tos in flowi4_update_output().

Guillaume Nault authored
All callers already initialise ->flowi4_scope with RT_SCOPE_UNIVERSE, either by manual field assignment, memset(0) of the whole structure or implicit structure initialisation of on-stack variables (RT_SCOPE_UNIVERSE actually equals 0). Therefore, we don't need to always initialise ->flowi4_scope in ip_rt_fix_tos(). We only need to reduce the scope to RT_SCOPE_LINK when the special RTO_ONLINK flag is present in the tos. This will allow some code simplification, like removing ip_rt_fix_tos(). Also, the long term idea is to remove RTO_ONLINK entirely by properly initialising ->flowi4_scope, instead of overloading ->flowi4_tos with a special flag. Eventually, this will allow to convert ->flowi4_tos to dscp_t. Signed-off-by:
