| * selftests: netfilter: extend flowtable test script for ipsecFlorian Westphal2019-08-051-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'flow offload' expression should not offload flows that will be subject to ipsec, but it does. This results in a connectivity blackhole for the affected flows -- first packets will go through (offload happens after established state is reached), but all remaining ones bypass ipsec encryption and are thus discarded by the peer. This can be worked around by adding "rt ipsec exists accept" before the 'flow offload' rule matches. This test case will fail, support for such flows is added in next patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add 2 tests that check JIT code generation to jumps to 1st insn. 1st test is similar to syzbot reproducer. The backwards branch is never taken at runtime. 2nd test has branch to 1st insn that executes. The test is written as two bpf functions, since it's not possible to construct valid single bpf program that jumps to 1st insn.

This selftest was created together with a fix for generic XDP, in commit 297249569932 ("net: fix generic XDP to handle if eth header was mangled"). And was suppose to catch if generic XDP was broken again. The tests are using veth and assumed that veth driver didn't support native driver XDP, thus it used the (ip link set) 'xdp' attach that fell back to generic-XDP. But veth gained native-XDP support in 948d4f214fde ("veth: Add driver XDP"), which caused this test script to use native-XDP.

Before loading a livepatch self-test kernel module, first verify that we've built and installed it by running a 'modprobe --dry-run'. This should catch a few environment issues, including !CONFIG_LIVEPATCH and !CONFIG_TEST_LIVEPATCH. In these cases, exit gracefully with the new skip() function.
