Title:
hangup01 from pty in ubuntu_ltp_stable failed on G-5.8
Status in ubuntu-kernel-tests:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Groovy:
Fix Released
Bug description:
[Impact]
Testcase hangup01 from ubuntu_ltp_stable.pty is failing on Groovy 5.8.0-51.57.
Test case failed with:
hangup01 1 TFAIL : hangup01.c:132: unexpected message 3
tag=hangup01 stime=1618856629 dur=1 exit=exited stat=1
It was found that the regression was introduced by the following
commits applied via stable uddates:
dd78b0c483e3 tty: implement read_iter
3b830a9c34d5 tty: convert tty_ldisc_ops 'read()' function to take a kernel pointer
These patches were applied via bug 1921960 ("Groovy update: upstream
stable patchset 2021-03-30").
[Fix]
Revert the patches mentioned above until a fix can be found.
[Test case]
Run the pty testsuite from ubuntu_ltp_stable.
[Where problems could occur]
If reverting these two patches is not enough to bring the code to the behavior of the tty driver before 5.8.0-51.57 then remaining issues could still be present on the tty code. Those issues should be caught by the ltp testcases though.
[Original Description]
Issue found on Groovy 5.8.0-51.57 with P8 node "dryden" and ARM64 node "helo-kernel" and AMD64 node "onibi"
Test case failed with:
hangup01 1 TFAIL : hangup01.c:132: unexpected message 3
tag=hangup01 stime=1618856629 dur=1 exit=exited stat=1
