2022-08-05selftests: mptcp: make sendfile selftest workFlorian Westphal1-9/+17
When the selftest got added, sendfile() on mptcp sockets returned -EOPNOTSUPP, so running 'mptcp_connect.sh -m sendfile' failed immediately. This is no longer the case, but the script fails anyway due to timeout. Let the receiver know once the sender has sent all data, just like with '-m mmap' mode. v2: need to respect cfg_wait too, as pm_userspace.sh relied on -m sendfile to keep the connection open (Mat Martineau) Fixes: 048d19d444be ("mptcp: add basic kselftest for mptcp") Reported-by: Xiumei Mu <[email protected]> Reviewed-by: Mat Martineau <[email protected]> Signed-off-by: Florian Westphal <[email protected]> Signed-off-by: Mat Martineau <[email protected]> Signed-off-by: David S.

2022-07-29selftests: seg6: add selftest for SRv6 H.L2Encaps.Red behaviorAndrea Mayer2-0/+822
This selftest is designed for testing the H.L2Encaps.Red behavior. It instantiates a virtual network composed of several nodes: hosts and SRv6 routers. Each node is realized using a network namespace that is properly interconnected to others through veth pairs. The test considers SRv6 routers implementing a L2 VPN leveraged by hosts for communicating with each other. Such routers make use of the SRv6 H.L2Encaps.Red behavior for applying SRv6 policies to L2 traffic coming from hosts. The correct execution of the behavior is verified through reachability tests carried out between hosts belonging to the same VPN.

2022-07-05selftests: forwarding: fix flood_unicast_test when h2 supports IFF_UNICAST_FLTVladimir Oltean1-0/+2
As mentioned in the blamed commit, flood_unicast_test() works by checking the match count on a tc filter placed on the receiving interface. But the second host interface (host2_if) has no interest in receiving a packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even before the ingress tc filter gets to be executed. So we will incorrectly get the message "Packet was not flooded when should", when in fact, the packet was flooded as expected but dropped due to an unrelated reason, at some other layer on the receiving side. Force h2 to accept this packet by temporarily placing it in promiscuous mode. Alternatively we could either deliver to its MAC address or use tcpdump_start, but this has the fewest complications. This fixes the "flooding" test from bridge_vlan_aware.sh and bridge_vlan_unaware.sh, which calls flood_test from the lib.

Since commit 8fffa0e3451a ("selftests/bpf: Normalize XDP section names in selftests") the xdp_dummy.o's section name has changed to xdp. But some tests are still using "section xdp_dummy", which make the tests failed. Fix them by updating to the new section name.

2022-06-29selftests: forwarding: ethtool_extended_state: Convert to busywaitPetr Machata1-15/+28
Currently, this script sets up the test scenario, which is supposed to end in an inability of the system to negotiate a link. It then waits for a bit, and verifies that the system can diagnose why the link was not established. The wait time for the scenario where different link speeds are forced on the two ends of a loopback cable, was set to 4 seconds, which exactly covered it. As of a recent mlxsw firmware update, this time gets longer, and this test starts failing. The time that selftests currently wait for links to be established is currently $WAIT_TIMEOUT, or 20 seconds. It seems reasonable that if this is the time necessary to establish and bring up a link, it should also be enough to determine that a link cannot be established and why. Therefore in this patch, convert the sleeps to busywaits, so that if a failure is established sooner (as is expected), the test runs quicker. And use $WAIT_TIMEOUT as the time to wait.

2022-06-28selftests: mptcp: Initialize variables to quiet gcc 12 warningsMat Martineau3-3/+3
In a few MPTCP selftest tools, gcc 12 complains that the 'sock' variable might be used uninitialized. This is a false positive because the only code path that could lead to uninitialized access is where getaddrinfo() fails, but the local xgetaddrinfo() wrapper exits if such a failure occurs. Initialize the 'sock' variable anyway to allow the tools to build with gcc 12.

The mentioned test-case still use an hard-coded-len sleep to wait for a relative large number of connection to be established. On very slow VM and with debug build such timeout could be exceeded, causing failures in our CI. Address the issue polling for the expected condition several times, up to an unreasonable high amount of time. On reasonably fast system the self-tests will be faster then before, on very slow one we will still catch the correct condition.

2022-06-20ipv4: fix bind address validity regression testsRiccardo Paolo Bestetti1-9/+27
Commit 8ff978b8b222 ("ipv4/raw: support binding to nonlocal addresses") introduces support for binding to nonlocal addresses, as well as some basic test coverage for some of the related cases. Commit b4a028c4d031 ("ipv4: ping: fix bind address validity check") fixes a regression which incorrectly removed some checks for bind address validation. In addition, it introduces regression tests for those specific checks. However, those regression tests are defective, in that they perform the tests using an incorrect combination of bind flags. As a result, those tests fail when they should succeed. This commit introduces additional regression tests for nonlocal binding and fixes the defective regression tests. It also introduces new set_sysctl calls for the ipv4_bind test group, as to perform the ICMP binding tests it is necessary to allow ICMP socket creation by setting the net.ipv4.ping_group_range knob.

2022-06-17ipv4: ping: fix bind address validity checkRiccardo Paolo Bestetti1-0/+33
Commit 8ff978b8b222 ("ipv4/raw: support binding to nonlocal addresses") introduced a helper function to fold duplicated validity checks of bind addresses into inet_addr_valid_or_nonlocal(). However, this caused an unintended regression in ping_check_bind_addr(), which previously would reject binding to multicast and broadcast addresses, but now these are both incorrectly allowed as reported in [1]. This patch restores the original check. A simple reordering is done to improve readability and make it evident that multicast and broadcast addresses should not be allowed. Also, add an early exit for INADDR_ANY which replaces lost behavior added by commit 0ce779a9f501 ("net: Avoid unnecessary inet_addr_type() call when addr is INADDR_ANY"). Furthermore, this patch introduces regression selftests to catch these specific cases.

2022-06-17selftests: mirror_gre_bridge_1q_lag: Enslave port to bridge before other ↵Amit Cohen1-3/+4
configurations Using mlxsw driver, the configurations are offloaded just in case that there is a physical port which is enslaved to the virtual device (e.g., to a bridge). In 'mirror_gre_bridge_1q_lag' test, the bridge gets an address and route before there are ports in the bridge. It means that these configurations are not offloaded. Till now the test passes with mlxsw driver even that the RIF of the bridge is not in the hardware, because the ARP packets are trapped in layer 2 and also mirrored, so there is no real need of the RIF in hardware. The previous patch changed the traps 'ARP_REQUEST' and 'ARP_RESPONSE' to be done at layer 3 instead of layer 2. With this change the ARP packets are not trapped during the test, as the RIF is not in the hardware because of the order of configurations. Reorder the configurations to make them to be offloaded, then the test will pass with the change of the traps.
