2020-10-30wireguard: selftests: check that route_me_harder packets use the right skJason A. Donenfeld2-0/+10
If netfilter changes the packet mark, the packet is rerouted. The ip_route_me_harder family of functions fails to use the right sk, opting to instead use skb->sk, resulting in a routing loop when used with tunnels. With the next change fixing this issue in netfilter, test for the relevant condition inside our test suite, since wireguard was where the bug was discovered.

2020-10-27selftests/ftrace: Use $FUNCTION_FORK to reference kernel fork functionSteven Rostedt (VMware)19-37/+44
Commit cad6967ac108 ("fork: introduce kernel_clone()") replaced "_do_fork()" with "kernel_clone()". The ftrace selftests reference the fork function in several of the tests. The rename will make the tests break, but if those names are changed in the tests, they would then break on older kernels. The same set of tests should pass older kernels if they have previously passed. Obviously, a new test may not work on older kernels if the test was added due to a bug or a new feature. The setup of ftracetest will now create a $FUNCTION_FORK bash variable that will contain "_do_fork" for older kernels and "kernel_clone" for newer ones. It figures out the proper name by examining /proc/kallsyms. Note, available_filter_functions could also be used, but because some tests should be able to pass without function tracing enabled, it could not be used.

2020-10-26staging: ion: remove from the treeGreg Kroah-Hartman16-1278/+1
The ION android code has long been marked to be removed, now that we dma-buf support merged into the real part of the kernel. It was thought that we could wait to remove the ion kernel at a later time, but as the out-of-tree Android fork of the ion code has diverged quite a bit, and any Android device using the ion interface uses that forked version and not this in-tree version, the in-tree copy of the code is abandonded and not used by anyone. Combine this abandoned codebase with the need to make changes to it in order to keep the kernel building properly, which then causes merge issues when merging those changes into the out-of-tree Android code, and you end up with two different groups of people (the in-kernel-tree developers, and the Android kernel developers) who are both annoyed at the current situation. Because of this problem, just drop the in-kernel copy of the ion code now, as it's not used, and is only causing problems for everyone involved.

2020-10-21selftests: mptcp: depends on built-in IPv6Matthieu Baerts1-0/+1
Recently, CONFIG_MPTCP_IPV6 no longer selects CONFIG_IPV6. As a consequence, if CONFIG_MPTCP_IPV6=y is added to the kconfig, it will no longer ensure CONFIG_IPV6=y. If it is not enabled, CONFIG_MPTCP_IPV6 will stay disabled and selftests will fail. We also need CONFIG_IPV6 to be built-in. For more details, please see commit 0ed37ac586c0 ("mptcp: depends on IPV6 but not as a module"). Note that 'make kselftest-merge' will take all 'config' files found in 'tools/testsing/selftests'. Because some of them already set CONFIG_IPV6=y, MPTCP selftests were still passing. But they will fail if MPTCP selftests are launched manually after having executed this command to prepare the kernel config: ./scripts/kconfig/merge_config.sh -m .config \ ./tools/testing/selftests/net/mptcp/config Fixes: 010b430d5df5 ("mptcp: MPTCP_IPV6 should depend on IPV6 instead of selecting it") Signed-off-by: Matthieu Baerts <[email protected]> Reviewed-by: Mat Martineau <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
2020-10-22bpf, selftests: Extend test_tc_redirect to use modified bpf_redirect_neigh()Toke Høiland-Jørgensen3-5/+173
This updates the test_tc_neigh prog in selftests to use the new syntax of bpf_redirect_neigh(). To exercise the helper both with and without the optional parameter, add an additional test_tc_neigh_fib test program, which does a bpf_fib_lookup() followed by a call to bpf_redirect_neigh() instead of looking up the ifindex in a map. Update the test_tc_redirect.sh script to run both versions of the test, and while we're add it, fix it to work on systems that have a consolidated dual-stack 'ping' binary instead of separate ping/ping6 versions.

2020-10-20selftests/powerpc: Make alignment handler test P9N DD2.1 vector CI load ↵Michael Neuling1-2/+6
workaround alignment_handler currently only tests the unaligned cases but it can also be useful for testing the workaround for the P9N DD2.1 vector CI load issue fixed by p9_hmi_special_emu(). This workaround was introduced in 5080332c2c89 ("powerpc/64s: Add workaround for P9 vector CI load issue"). This changes the loop to start from offset 0 rather than 1 so that we test the kernel emulation in p9_hmi_special_emu().
