perf ui gtk: Add missing zalloc object

2020-03-05T15:43:50+00:00

commit 604e2139a1026793b8c2172bd92c7e9d039a5cf0 upstream. When we moved zalloc.o to the library we missed gtk library which needs it compiled in, otherwise the missing __zfree symbol will cause the library to fail to load. Adding the zalloc object to the gtk library build.

selftests: Install settings files to fix TIMEOUT failures

2020-03-05T15:43:47+00:00

commit b9167c8078c3527de6da241c8a1a75a9224ed90a upstream. Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") added a 45 second timeout for tests, and also added a way for tests to customise the timeout via a settings file. For example the ftrace tests take multiple minutes to run, so they were given longer in commit b43e78f65b1d ("tracing/selftests: Turn off timeout setting"). This works when the tests are run from the source tree. However if the tests are installed with "make -C tools/testing/selftests install", the settings files are not copied into the install directory. When the tests are then run from the install directory the longer timeouts are not applied and the tests timeout incorrectly. So add the settings files to TEST_FILES of the appropriate Makefiles to cause the settings files to be installed using the existing install logic.

ipv6: Fix route replacement with dev-only route

2020-03-05T15:43:35+00:00

[ Upstream commit e404b8c7cfb31654c9024d497cec58a501501692 ] After commit 27596472473a ("ipv6: fix ECMP route replacement") it is no longer possible to replace an ECMP-able route by a non ECMP-able route. For example, ip route add 2001:db8::1/128 via fe80::1 dev dummy0 ip route replace 2001:db8::1/128 dev dummy0 does not work as expected. Tweak the replacement logic so that point 3 in the log of the above commit becomes: 3. If the new route is not ECMP-able, and no matching non-ECMP-able route exists, replace matching ECMP-able route (if any) or add the new route. We can now summarize the entire replace semantics to: When doing a replace, prefer replacing a matching route of the same "ECMP-able-ness" as the replace argument. If there is no such candidate, fallback to the first route found.

bpf: Selftests build error in sockmap_basic.c

commit f2e97dc126b712c0d21219ed0c42710006c1cf52 upstream. Fix following build error.

selftests/eeh: Bump EEH wait time to 60s

2020-02-24T07:36:57+00:00

[ Upstream commit 414f50434aa2463202a5b35e844f4125dd1a7101 ] Some newer cards supported by aacraid can take up to 40s to recover after an EEH event. This causes spurious failures in the basic EEH self-test since the current maximim timeout is only 30s. Fix the immediate issue by bumping the timeout to a default of 60s, and allow the wait time to be specified via an environmental variable (EEH_MAX_WAIT).

[ Upstream commit 51bad0f05616c43d6d34b0a19bcc9bdab8e8fb39 ] Currently, there is a lot of false positives if a single reuseport test fails.
