This failure can be reproduced with the kernel in -release 4.4.0-130-generic, therefore it should not be considered as a regression.

If you run only this test after a reboot, it will pass for the first time.

    msgctl02.c:47: PASS: msgctl(IPC_SET) msg_qbytes - 1
    msgctl02.c:54: PASS: msg_qbytes = 16383

There is a recent change for msgctl02 (79eac0a) in the ltp repo. This test can pass with with commit revert back to 1a11467414
