selftest/net/xfrm: Add test for ipsec tunnel
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.
