binfmt_misc02 in LTP kernel/fs/ failed with Bionic

[Po-Hsu Lin]

Found on a KVM node, I think this test case might need some investigation, as the LTP suite should be chop down into pieces like the syscalls variant.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1822246

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Tried to run the test with TST_DISABLE_APPARMOR=1, but it seems this is not working as well:
root@zeppo:/opt/ltp# export TST_DISABLE_APPARMOR=1
root@zeppo:/opt/ltp# ./runltp -f /tmp/a

This test was skipped on KVM kernels:
    binfmt_misc02 1 TCONF: binfmt_misc driver not available

[Sean Feole (sfeole)]

This may be unrelated however the failure is also found on disco, 5.0 kernel. The actual failure messages themselves are the same, this is on the AWS Cloud, across all instance types.
This relatively new test was added back in Feb.

This upstream fix seems to fix the problem. I will reply with a Tested-by.
