Hi Mat, we had checked test status on v5.7-rc1, which has the below failures

  "kernel-selftests.bpf.test_progs.fail": [
  "kernel-selftests.bpf.test_align.fail": [
  "kernel-selftests.bpf.test_tcpbpf_user.fail": [	<== new in v5.7-rc1
  "kernel-selftests.bpf.test_btf.fail": [
  "kernel-selftests.bpf.test_sysctl.fail": [
  "kernel-selftests.bpf.test_progs-no_alu32.fail": [
  "kernel-selftests.bpf.test_bpftool.sh.fail": [
  "kernel-selftests.bpf.test_tc_edt.sh.pass"		<== pass in v5.7-rc1

v5.7-rc1 had extra "kernel-selftests.bpf.test_tcpbpf_user.fail", but with
kernel-selftests.bpf.test_tc_edt.sh.pass, which failed in 531346f5a4531c here.

We haven't root caused them yet, will plan some effort to see whether the test
is stable and try to resolve other failure if it is env issue.

Thanks

Hi Mat, we will follow up to provide test data.

Currently, if the fail is not regression, which means failsure is also existed
on v5.6. The cause can be our test environment, we will continue to solving them
to avoid confusion.

Are these failures also present on net-next or Linus' 5.7-rc1+ tree? The 
message does say the test status is compared to v5.6, but the mptcp tree 
has only minor changes from net-next right now so it seems like there may 
be underlying problems not related to mptcp.

Thanks for sharing the test status for the mptcp repo!
