2024-08-16selftests: net: bridge_vlan_aware: test that other TPIDs are seen as untaggedVladimir Oltean1-1/+53
The bridge VLAN implementation w.r.t. VLAN protocol is described in merge commit 1a0b20b25732 ("Merge branch 'bridge-next'"). We are only sensitive to those VLAN tags whose TPID is equal to the bridge's vlan_protocol. Thus, an 802.1ad VLAN should be treated as 802.1Q-untagged. Add 3 tests which validate that: - 802.1ad-tagged traffic is learned into the PVID of an 802.1Q-aware bridge - Double-tagged traffic is forwarded when just the PVID of the port is present in the VLAN group of the ports - Double-tagged traffic is not forwarded when the PVID of the port is absent from the VLAN group of the ports The test passes with both veth and ocelot.

2024-08-16selftests: net: local_termination: add PTP frames to the mixVladimir Oltean1-13/+148
A breakage in the felix DSA driver shows we do not have enough test coverage. More generally, it is sufficiently special that it is likely drivers will treat it differently. This is not meant to be a full PTP test, it just makes sure that PTP packets sent to the different addresses corresponding to their profiles are received correctly. The local_termination selftest seemed like the most appropriate place for this addition. PTP RX/TX in some cases makes no sense (over a bridge) and this is why $skip_ptp exists. And in others - PTP over a bridge port - the IP stack needs convincing through the available bridge netfilter hooks to leave the PTP packets alone and not stolen by the bridge rx_handler. It is safe to assume that users have that figured out already. This is a driver level test, and by using tcpdump, all that extra setup is out of scope here. send_non_ip() was an unfinished idea; written but never used. Replace it with a more generic send_raw(), and send 3 PTP packet types times 3 transports. Signed-off-by: Vladimir Oltean <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2024-08-16selftests: net: local_termination: don't use xfail_on_veth()Vladimir Oltean2-16/+99
xfail_on_veth() for this test is an incorrect approximation which gives false positives and false negatives. When local_termination fails with "reception succeeded, but should have failed", it is because the DUT ($h2) accepts packets even when not configured as promiscuous. This is not something specific to veth; even the bridge behaves that way, but this is not captured by the xfail_on_veth test. The IFF_UNICAST_FLT flag is not explicitly exported to user space, but it can somewhat be determined from the interface's behavior. We have to create a macvlan upper with a different MAC address. This forces a dev_uc_add() call in the kernel. When the unicast filtering list is not empty, but the device doesn't support IFF_UNICAST_FLT, __dev_set_rx_mode() force-enables promiscuity on the interface, to ensure correct behavior (that the requested address is received). We can monitor the change in the promiscuity flag and infer from it whether the device supports unicast filtering. There is no equivalent thing for allmulti, unfortunately. We never know what's hiding behind a device which has allmulti=off. Whether it will actually perform RX multicast filtering of unknown traffic is a strong "maybe". The bridge driver, for example, completely ignores the flag. We'll have to keep the xfail behavior, but instead of XFAIL on just veth, always XFAIL.

2024-08-16selftests: net: local_termination: add one more test for VLAN-aware bridgesVladimir Oltean1-4/+18
The current bridge() test is for packet reception on a VLAN-unaware bridge. Some things are different enough with VLAN-aware bridges that it's worth renaming this test into vlan_unaware_bridge(), and add a new vlan_aware_bridge() test. The two will share the same implementation: bridge() becomes a common function, which receives $vlan_filtering as an argument. Rename it to test_bridge() at the same time, because just bridge() pollutes the global namespace and we cannot invoke the binary with the same name from the iproute2 package currently.

There are upcoming tests which verify the RX filtering of a bridge (or bridge port), but under differing vlan_filtering conditions. Since we currently print $h2 (the DUT) in the log_test() output, it becomes necessary to make a further distinction between tests, to not give the user the impression that the exact same thing is run twice.

When deleting netns, it is possible to still have some tasks running, e.g. background tasks like tcpdump running in the background, not stopped because the test has been interrupted. Before deleting the netns, it is then safer to kill all attached PIDs, if any. That should reduce some noises after the end of some tests, and help with the debugging of some issues.

2024-08-13selftests/bpf: Avoid subtraction after htons() in ipip testsAsbjørn Sloth Tønnesen1-6/+6
On little-endian systems, doing subtraction after htons() leads to interesting results: Given: MAGIC_BYTES = 123 = 0x007B aka. in big endian: 0x7B00 = 31488 sizeof(struct iphdr) = 20 Before this patch: __bpf_constant_htons(MAGIC_BYTES) - sizeof(struct iphdr) = 0x7AEC 0x7AEC = htons(0xEC7A) = htons(60538) So these were outer IP packets with a total length of 123 bytes, containing an inner IP packet with a total length of 60538 bytes. After this patch: __bpf_constant_htons(MAGIC_BYTES - sizeof(struct iphdr)) = htons(103) Now these packets are outer IP packets with a total length of 123 bytes, containing an inner IP packet with a total length of 103 bytes.

A selftest is added such that without the previous patch, a crash can happen. With the previous patch, the test can run successfully. The new test is written in a way which mimics original crash case: main_prog static_prog_1 static_prog_2 where static_prog_1 has different paths to static_prog_2 and some path has stack allocated and some other path does not. A stacksafe() checking in static_prog_2() triggered the crash.

Currently, cxl_setup_parent_dport() is used to set up RAS and AER capability on the dport connected to the CXL memory device, but cxl_test does not support RAS or AER functionality yet, so the fix is implementing a __wrap_cxl_setup_parent_dport() to filter out all emulated dports, guarantees only real dports can be handled by cxl_setup_parent_dport().

Currently the only opportunity to set sock ops flags dictating which callbacks fire for a socket is from within a TCP-BPF sockops program. This is problematic if the connection is already set up as there is no further chance to specify callbacks for that socket. Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_setsockopt() and bpf_getsockopt() to allow users to specify callbacks later, either via an iterator over sockets or via a socket-specific program triggered by a setsockopt() on the socket.
