2025-05-05selftests: mptcp: refactor send_query parameters for code clarityGang Yan
This patch use 'inet_diag_req_v2' instead of 'token' as parameters of send_query, and construct the req in 'get_mptcpinfo'. This modification enhances the clarity of the code, and prepare for the dump_subflow_info.

2025-05-05selftests: mptcp: sockopt: use IPPROTO_MPTCP for getaddrinfoGeliang Tang
getaddrinfo MPTCP is recently supported in glibc and IPPROTO_MPTCP for getaddrinfo is used in mptcp_connect.c. But in mptcp_sockopt.c and mptcp_inq.c, IPPROTO_TCP are still used for getaddrinfo, So this patch updates them.

2025-05-05selftests: mptcp: info: hide 'grep: write error' warningsMatthieu Baerts (NGI0)
mptcp_lib_get_info_value() will only print the first entry that match the filter because of the ';q' at the end. As a consequence, the 'sed' command could finish before the previous 'grep' one and print a 'write error' warning because it is trying to write data to the closed pipe. Such warnings are not interesting, they can be hidden by muting stderr here for grep. While at it, clearly indicate that mptcp_lib_get_info_value() will only print the first matched entry to avoid confusions later on.

2025-05-02selftests/bpf: Add tests for bucket resume logic in UDP socket iteratorsJordan Rife
Introduce a set of tests that exercise various bucket resume scenarios: * remove_seen resumes iteration after removing a socket from the bucket that we've already processed. Before, with the offset-based approach, this test would have skipped an unseen socket after resuming iteration. With the cookie-based approach, we now see all sockets exactly once. * remove_unseen exercises the condition where the next socket that we would have seen is removed from the bucket before we resume iteration. This tests the scenario where we need to scan past the first cookie in our remembered cookies list to find the socket from which to resume iteration. * remove_all exercises the condition where all sockets we remembered were removed from the bucket to make sure iteration terminates and returns no more results. * add_some exercises the condition where a few, but not enough to trigger a realloc, sockets are added to the head of the current bucket between reads. Before, with the offset-based approach, this test would have repeated sockets we've already seen. With the cookie-based approach, we now see all sockets exactly once. * force_realloc exercises the condition that we need to realloc the batch on a subsequent read, since more sockets than can be held in the current batch array were added to the current bucket. This exercies the logic inside bpf_iter_udp_realloc_batch that copies cookies into the new batch to make sure nothing is skipped or repeated.

2025-04-29selftests: net: tc_taprio: new testVladimir Oltean
Add a forwarding path test for tc-taprio, based on isochron. This is specifically intended for NICs with an offloaded data path (switchdev/DSA) and requires taprio 'flags 2'. Also, $h1 and $h2 must support hardware timestamping, and $h1 tc-etf offload, for isochron to work. Packets received by a switch while the egress port has a taprio schedule with an open gate for the traffic class must be sent right away. Packets received by the switch while the traffic class gate must be delayed until it opens. Packets received by the switch must be dropped if the gate for the traffic class never opens. Packets should pass if the maximum SDU for the traffic class allows it, and should be dropped otherwise. The schedule should auto-update itself if clock jumps take place while taprio is installed. Repeat most of the above tests after forcing two clock jumps, one backwards (in Jan 1970) and one back into the present. Symlink it from tools/testing/selftests/drivers/net/dsa, because usually DSA ports have the same MAC address, and we need STABLE_MAC_ADDRS=yes from its forwarding.config for the test to run successfully.

2025-04-29selftests: net: tsn_lib: add window_size argument to isochron_do()Vladimir Oltean
Make out-of-band testing (send a packet when its traffic class gate is closed, expecting it to be delayed) more predictable by allowing the window size to be customized by isochron_do(). From man isochron-send, the window size alters the advance time (the delta between the transmission time of the packet, and its expected TX time when using SO_TXTIME or tc-taprio on the sender). In absence of the argument, isochron-send defaults to maximizing the advance time (making it equal to the cycle length). The default behavior is exactly what is problematic. An advance time that is too large will make packets intended to be out-of-band still be potentially in-band with an open gate from the schedule's previous cycle. We need to allow that advance time to be reduced. Perhaps a bit confusingly, isochron_do() has a shift_time argument currently, but that does not help here. The shift time shifts both the user space wakeup time and the expected TX time by equal amounts, it is unable of bringing them closer to one another. Set the window size properly for the Ocelot PSFP selftest as well. That used to work due to a very carefully chosen SHIFT_TIME_NS. I've re-tested that the test still works properly.

Commit 57e13a2e8cd2 ("selftests: ublk: support user recovery") starts to support UBLK_F_NEED_GET_DATA for covering recovery feature, however the ublk utility implementation isn't done correctly. Fix it by supporting UBLK_F_NEED_GET_DATA correctly. Also add test generic_07 for covering UBLK_F_NEED_GET_DATA.

2025-04-25selftests: net: bridge_vlan_aware: test untagged/8021p-tagged with and ↵Vladimir Oltean
without PVID Recent discussions around commit ad1afb003939 ("vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)") have sparked the question what happens with the DSA (and possibly other switchdev) data path when the bridge says that ports should have no PVID VLAN, but the 8021q module, as the result of a NETDEV_UP event, decides it should add VID 0 to the RX filter of those bridge ports. Do those bridge ports receive packets tagged with VID 0 or not, now? We don't know, there is no test. In the veth realm, this passes trivially, because veth is not VLAN filtering and this, the 8021q module lacks the instinct to add VID 0 in the first place. In the realm of VLAN filtering NICs with no switchdev offload, this should also pass, because the VLAN groups of the software bridge are consulted, where it can clearly be seen that a PVID is missing, even though the packet was initially accepted by the NIC. The test only poses a challenge for switchdev drivers, which usually have to program to hardware both VLANs from RX filtering, as well as from switchdev. Especially when a switchdev port joins a VLAN-aware bridge, it is unavoidable that it gains the NETIF_F_HW_VLAN_CTAG_FILTER feature, i.e. any 8021q uppers that the bridge port may have must also be committed to the RX filtering table of the interface. When a VLAN-tagged packet is physically received by the port, it is initially indistinguishable whether it will reach the bridge data path or the 8021q upper data path. That is rather the final step of the new tests that we introduce. We need to build context up to that stage, which means the following: - we need to test that 802.1p (VID 0) tagged traffic is received in the first place (on bridge ports with a valid PVID). This is the "8021p" test. - we need to test that the usual paths of reaching a configuration with no PVID on a bridge port are all covered and they all reach the same state.
