Title:
lp1153769 in ubuntu_cts_kernel failed on P with logfd error
Status in ubuntu-kernel-tests:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
If you run it on jenkins remotely:
~/kernel-testing/remote --kernel-test-list=ubuntu_cts_kernel ubuntu@rizzo
It will fail with:
*** lp1153769 ***
Running '/home/ubuntu/autotest/client/tests/ubuntu_cts_kernel/bugs/lp1153769
eno1'
[stderr] Failed opening logfd: Invalid argument
Exception escaping from test:

This can be reproduced with just ssh on the host to SUT:
$ myssh rizzo
"/home/ubuntu/autotest/client/tests/ubuntu_cts_kernel/bugs/lp1153769 eno1"
Warning: Permanently added 'rizzo,10.246.72.30' (ECDSA) to the list of known
hosts.
Failed opening logfd: Invalid argument
But if you run this test locally on the SUT, it will pass without any
issue:
sudo apt-get install git python-minimal gdb -y
git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests
git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest
rm -fr autotest/client/tests
ln -sf ~/autotest-client-tests autotest/client/tests
AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local
--verbose autotest/client/tests/ubuntu_cts_kernel/control
Or just run the test directly on the SUT:
$ /home/ubuntu/autotest/client/tests/ubuntu_cts_kernel/bugs/lp1153769 eno1
autotest kernel-test-results kernel-testing

I think this has something to do with the perf command and the shell
