2022-06-29selftests: forwarding: ethtool_extended_state: Convert to busywaitPetr Machata
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.

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.

2022-06-20ipv4: fix bind address validity regression testsRiccardo Paolo Bestetti
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 Bestetti
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 Cohen
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.

RFC 9131 changes default behaviour of handling RX of NA messages when the corresponding entry is absent in the neighbour cache. The current implementation is limited to accept just unsolicited NAs. However, the RFC is more generic where it also accepts solicited NAs. Both types should result in adding a STALE entry for this case. Expand accept_untracked_na behaviour to also accept solicited NAs to be compliant with the RFC and rename the sysctl knob to accept_untracked_na.

bhash entry This test populates the bhash table for a given port with MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long a bind request on the port takes. When populating the bhash table, we create the sockets and then bind the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT are set). When timing how long a bind on the port takes, we bind on a different address without SO_REUSEPORT set. We do not set SO_REUSEPORT because we are interested in the case where the bind request does not go through the tb->fastreuseport path, which is fragile (eg tb->fastreuseport path does not work if binding with a different uid).

Add the multiple subflows test case for MP_FAIL, to test the MP_FAIL reset case. Use the test_linkfail value to make 1024KB test files.

Add delays on ns2eth1 to make sure more data can translate on ns2eth2. The check_invert flag is enabled in reset_with_fail(), so this test prints out the inverted bytes, instead of the file mismatch errors.

The function get_l3_stats() from the test hw_stats_l3.sh will be useful for any test that wishes to work with L3 stats. Furthermore, it is easy to generalize to other HW stats suites (for when such are added). Therefore, move the code to lib.sh, rewrite it to have the same interface as the other stats-collecting functions, and generalize to take the name of the HW stats suite to collect as an argument.

2022-05-05selftests: add ping test with ping_group_range tunedNicolas Dichtel
The 'ping' utility is able to manage two kind of sockets (raw or icmp), depending on the sysctl ping_group_range. By default, ping_group_range is set to '1 0', which forces ping to use an ip raw socket. Let's replay the ping tests by allowing 'ping' to use the ip icmp socket. After the previous patch, ipv4 tests results are the same with both kinds of socket. For ipv6, there are a lot a new failures (the previous patch fixes only two cases).

This change updates the "pm_nl_ctl" testing sample with a "listen" option to bind a MPTCP listening socket to the provided addr+port. This option is exercised in testing subflow initiation scenarios in conjunction with userspace path managers where the MPTCP application does not hold an active listener to accept requests for new subflows.

This change adds to self-testing support for the MPTCP netlink interface by capturing various MPTCP netlink events (and all their metadata) associated with connections, subflows and address announcements. It is used in self-testing scripts that exercise MPTCP netlink commands to precisely validate those operations by examining the dispatched MPTCP netlink events in response to those commands.

Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when there is an active userspace daemon. If the daemon is restarting or hasn't loaded yet, the missing echo will cause the peer to retransmit the ADD_ADDR - and hopefully the daemon will be ready to receive it at that later time.
