selftests/net: bump timeout to 5 minutes

2021-04-23T21:08:58+00:00

We found that with the latest mainline kernel (5.12.0-051200rc8) on some KVM instances / bare-metal systems, the following tests will take longer than the kselftest framework default timeout (45 seconds) to run and thus got terminated with TIMEOUT error: * xfrm_policy.sh - took about 2m20s * pmtu.sh - took about 3m5s * udpgso_bench.sh - took about 60s Bump the timeout setting to 5 minutes to allow them have a chance to finish. https://bugs.launchpad.net/bugs/1856010 Signed-off-by: Po-Hsu Lin Signed-off-by: David S.

self-tests: add veth tests

2021-04-11T23:39:28+00:00

Add some basic veth tests, that verify the expected flags and aggregation with different setups (default, xdp, etc...) Signed-off-by: Paolo Abeni Signed-off-by: David S. Miller

selftests: net: add UDP GRO forwarding self-tests

2021-03-31T00:06:50+00:00

Create a bunch of virtual topologies and verify that NETIF_F_GRO_FRAGLIST or NETIF_F_GRO_UDP_FWD-enabled devices aggregate the ingress packets as expected. Additionally check that the aggregate packets are segmented correctly when landing on a socket Also test SKB_GSO_FRAGLIST and SKB_GSO_UDP_L4 aggregation on top of UDP tunnel (vxlan) v1 -> v2: - hopefully clarify the commit message - moved the overlay network ipv6 range into the 'documentation' reserved range (Willem) Signed-off-by: Paolo Abeni Acked-by: Willem de Bruijn Signed-off-by: David S.

selftests: add IPv4 unicast extensions tests

2021-01-27T01:52:16+00:00

Add selftests for kernel behavior with regard to various classes of unallocated/reserved IPv4 addresses, checking whether or not these addresses can be assigned as unicast addresses on links and used in routing. Expect the current kernel behavior at the time of this patch. That is: * 0/8 and 240/4 may be used as unicast, with the exceptions of 0.0.0.0 and 255.255.255.255; * the lowest address in a subnet may only be used as a broadcast address; * 127/8 may not be used as unicast (the route_localnet option, which is disabled by default, still leaves it treated slightly specially); * 224/4 may not be used as unicast.

selftests: add test script for bareudp tunnels

2020-11-02T23:23:27+00:00

Test different encapsulation modes of the bareudp module: * Unicast MPLS, * IPv4 only, * IPv4 in multiproto mode (that is, IPv4 and IPv6), * IPv6. Each mode is tested with both an IPv4 and an IPv6 underlay. v2: * Add build dependencies in config file (Willem de Bruijn). * The MPLS test now uses its own IP addresses. This minimises the amount of cleanup between tests and simplifies the script. * Verify that iproute2 supports bareudp tunnels before running the script (and other minor usability improvements).

selftests: Add VRF route leaking tests

2020-10-15T00:14:28+00:00

The objective of the tests is to check that ICMP errors generated while crossing between VRFs are properly routed back to the source host. The first ttl test sends a ping with a ttl of 1 from h1 to h2 and parses the output of the command to check that a ttl expired error is received. The second ttl test runs traceroute from h1 to h2 and parses the output to check for a hop on r1. The mtu test sends a ping with a payload of 1450 from h1 to h2, through r1 which has an interface with a mtu of 1400 and parses the output of the command to check that a fragmentation needed error is received. [ The IPv6 MTU test still fails with the symmetric routing setup. It appears to be caused by source address selection picking ::1. Fixing this is beyond the scope of this series. ] Signed-off-by: Michael Jeanson Reviewed-by: David Ahern Signed-off-by: Jakub Kicinski

selftest/net/xfrm: Add test for ipsec tunnel

2020-09-24T06:53:04+00:00

It's an exhaustive testing for ipsec: covering all encryption/ authentication/compression algorithms. The tests are run in two network namespaces, connected by veth interfaces. To make exhaustive testing less time-consuming, the tests are run in parallel tasks, specified by parameter to the selftest. As the patches set adds support for xfrm in compatible tasks, there are tests to check structures that differ in size between 64-bit and 32-bit applications. The selftest doesn't use libnl so that it can be easily compiled as compatible application and don't require compatible .so. Here is a diagram of the selftest: --------------- | selftest | | (parent) | --------------- | | | (pipe) | ---------- / | | \ /------------- / \ -------------\ | /----- -----\ | ---------|----------|----------------|----------|--------- | --------- --------- --------- --------- | | | child | | child | NS A | child | | child | | | --------- --------- --------- --------- | -------|------------|----------------|-------------|------ veth0 veth1 veth2 vethN ---------|------------|----------------|-------------|---------- | ------------ ------------ ------------ ------------ | | | gr.child | | gr.child | NS B | gr.child | | gr.child | | | ------------ ------------ ------------ ------------ | ---------------------------------------------------------------- The parent sends the description of a test (xfrm parameters) to the child, the child and grand child setup a tunnel over veth interface and test it by sending udp packets.
