== SRU Justification [ FOCAL ] ==
The msg_zerocopy.sh kernel self test will fail on machines that don't have 2 or 3 CPUs such as 1 CPU cloud instances since the C test program tries to set CPU affinity to CPUs 2 and 3 and bails out if it fails.
== Fix ==
Upstream linux-next commit
commit 16f6458f2478b55e2b628797bc81a4455045c74e
Author: Willem de Bruijn <willemb@google.com>
Date: Wed Aug 5 04:40:45 2020 -0400
selftests/net: relax cpu affinity requirement in msg_zerocopy test
The fix now just emits a warning that CPU affinity can't be set rather than cause an exit(1) termination.
== Test cast ==
Run the msg_zerocopy.sh test from the kernel net selftest on a 1 CPU system. Without the fix the test fails. With the fix it runs successfully as expected.
== Regression Potential ==
The original test pinned the CPUs for a benchmarking metric, for our testing we are using this to test to see if the operations in the test work successfully. There is a potential that users using this test will not notice the warning if they are using this test as a benchmark on a 1 CPU system and may get more jittery timing in their benchmarks rather than a test failing and complaining they are not running it on a suitable multi-CPU system. However, the likelyhood of a user using this test on a single CPU system for benchmarking is small and as it stands the test will now run and produce potentially jittery benchmarks on a 1 CPU system compared to previously where it never ran.
