The UDP reuseport conflict was a little bit tricky. The net-next code, via bpf-next, extracted the reuseport handling into a helper so that the BPF sk lookup code could invoke it. At the same time, the logic for reuseport handling of unconnected sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace which changed the logic to carry on the reuseport result into the rest of the lookup loop if we do not return immediately. This requires moving the reuseport_has_conns() logic into the callers. While we are here, get rid of inline directives as they do not belong in foo.c files. The other changes were cases of more straightforward overlapping modifications. Signed-off-by: David S. Miller <[email protected]>
2020-07-23vrf: Handle CONFIG_SYSCTL not setDavid Ahern1-0/+6
Randy reported compile failure when CONFIG_SYSCTL is not set/enabled: ERROR: modpost: "sysctl_vals" [drivers/net/vrf.ko] undefined! Fix by splitting out the sysctl init and cleanup into helpers that can be set to do nothing when CONFIG_SYSCTL is disabled. In addition, move vrf_strict_mode and vrf_strict_mode_change to above vrf_shared_table_handler (code move only) and wrap all of it in the ifdef CONFIG_SYSCTL. Update the strict mode tests to check for the existence of the /proc/sys entry.

2020-07-06ipv6: fib6_select_path can not use out path for nexthop objectsDavid Ahern1-0/+13
Brian reported a crash in IPv6 code when using rpfilter with a setup running FRR and external nexthop objects. The root cause of the crash is fib6_select_path setting fib6_nh in the result to NULL because of an improper check for nexthop objects. More specifically, rpfilter invokes ip6_route_lookup with flowi6_oif set causing fib6_select_path to be called with have_oif_match set. fib6_select_path has early check on have_oif_match and jumps to the out label which presumes a builtin fib6_nh. This path is invalid for nexthop objects; for external nexthops fib6_select_path needs to just return if the fib6_nh has already been set in the result otherwise it returns after the call to nexthop_path_fib6_result. Update the check on have_oif_match to not bail on external nexthops. Update selftests for this problem.

2020-07-06selftests: mptcp: capture pcap on both sidesMatthieu Baerts1-4/+9
When investigating performance issues that involve latency / loss / reordering it is useful to have the pcap from the sender-side as it allows to easier infer the state of the sender's congestion-control, loss-recovery, etc. Allow the selftests to capture a pcap on both sender and receiver so that this information is not lost when reproducing. This patch also improves the file names. Instead of: ns4-5ee79a56-X4O6gS-ns3-5ee79a56-X4O6gS-MPTCP-MPTCP-10.0.3.1.pcap We now have something like for the same test: 5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-connector.pcap 5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-listener.pcap It was a connection from ns3 to ns4, better to start with ns3 then.

2020-06-23selftests/net: plug rxtimestamp test into kselftest frameworktannerlove3-2/+14
Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add new rxtimestamp.sh wrapper script, so that the test runs isolated from background traffic in a private network namespace. Also ignore failures of test case #6 by default. This case verifies that a receive timestamp is not reported if timestamp reporting is enabled for a socket, but generation is disabled. Receive timestamp generation has to be enabled globally, as no associated socket is known yet. A background process that enables rx timestamp generation therefore causes a false positive. Ntpd is one example that does. Add a "--strict" option to cause failure in the event that any test case fails, including test #6. This is useful for environments that are known to not have such background processes.

2020-06-08net/tls(TLS_SW): Add selftest for 'chunked' sendfile testPooja Trivedi1-0/+58
This selftest tests for cases where sendfile's 'count' parameter is provided with a size greater than the intended file size. Motivation: When sendfile is provided with 'count' parameter value that is greater than the size of the file, kTLS example fails to send the file correctly. Last chunk of the file is not sent, and the data integrity is compromised. The reason is that the last chunk has MSG_MORE flag set because of which it gets added to pending records, but is not pushed. Note that if user space were to send SSL_shutdown control message, pending records would get flushed and the issue would not happen. So a shutdown control message following sendfile can mask the issue.

Using ping in tests is error-prone, because ping is too smart. On a flaky system (notably in a simulator), when packets don't come quickly enough, more pings are sent, and that throws off counters. Instead use mausezahn to generate ICMP echo request packets.

2020-04-22selftests: A few improvements to fib_nexthops.shDavid Ahern1-11/+14
Add nodad when adding IPv6 addresses and remove the sleep. A recent change to iproute2 moved the 'pref medium' to the prefix (where it belongs). Change the expected route check to strip 'pref medium' to be compatible with old and new iproute2. Add IPv4 runtime test with an IPv6 address as the gateway in the default route.

2020-04-22selftests: Add tests for vrf and xfrmsDavid Ahern2-0/+437
Add tests for vrf and xfrms with a second round after adding a qdisc. There are a few known problems documented with the test cases that fail. The fix is non-trivial; will come back to it when time allows. Signed-off-by: David Ahern <[email protected]> Signed-off-by: David S. Miller <[email protected]>
