This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Regression potential] Though this is only changing the test, we might be missing or miss failures in the future because some tests are not executed anymore. ptrace_syscall_faked, ptrace_syscall_errno and syscall_errno should all work just fine on s390x, but will be skipped as well with this change. [Fix] The fix is to consider that s390x cannot change syscall and errno at once by using ptrace. It can, however, change the errno at syscall exit time, which could even be used with seccomp SECCOMP_RET_TRACE as long as ptrace is used to track the exit transitions. But the test is not designed to deal with such situations. [Test case] seccomp_bpf was run, ptrace_faked passed and no new subtests have failed. ------------------------------- This is a scripted bug report about ADT failures while running linux tests for linux/4.15.0-144.148 on bionic. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.
