Bug Description
The to-be-introduced 4.13 based kernel fails the kubernetes test suite (https:/
After rough bisecting (using kernels from http://
The minimal reproducer (doesn't have to be on a cloud image - my bionic desktop reproduces it just as well):
sudo apt install docker.io
sudo docker run -d gcr.io/
(note down returned hash)
sudo docker exec -it (first few chars of returned hash) /bin/sh
# (Inside the docker prompt)
timeout -t 1 cat
On kernels exhibiting the problem, the "timeout/cat" command above will terminate the container.
On kernels exhibiting the problem, docker logs exhibits:
# sudo docker logs (first few chars of returned hash)
/bin/sh: can't open /fifo: Interrupted system call
Kernels that do not exhibit the problem will not terminate after the "timeout" command and return to a normal command prompt.
