Summary0017089: runc version has issues when container pid 1 contains spaces in /proc/1/stat
DescriptionHey,

runc version has issues when container pid 1 contains spaces in /proc/1/stat. This bug was fixed in the upstream repo with this https://github.com/opencontainers/runc/pull/1136 pull request. Sadly the docker package in extras (1.13.1-108.git4ef4b30.el7.centos) ships an older version of runc.

We currently assume it comes from here https://github.com/projectatomic/runc/ (master branch) since the commit hash of docker info matches.

We also noticed that a runc package exists which ships a newer version of runc (which seems to be coming from the runc upstream repo https://github.com/opencontainers/runc). But dockers systemd service explicitly specifies its own runc binary.

The builds log contains the git hashes:
runc: https://buildlogs.centos.org/c7-extras.x86_64/runc/20190915140320/1.0.0-65.rc8.el7.centos.x86_64/build.log
docker: https://buildlogs.centos.org/c7-extras.x86_64/docker/20200121171404/1.13.1-108.git4ef4b30.el7.centos.x86_64/build.log
Steps To ReproduceAfter installing docker run a new container with a process with a space in /proc/1/stat

# docker run -d --rm --name cant_exec_me -it node:12-alpine -e "process.title = 'hi there'; setTimeout(() => {}, 100000)"

Try executing a command in that container

# docker exec -it cant_exec_me sh
rpc error: code = 2 desc = oci runtime error: exec failed: cannot exec a container that has run and stopped

RHEL seems to have a newer package (-109) where this is fixed.

Unsure about that, but is the current runc missing almost all commit since ee992e5ff7143ea3fedb1bb4aa88a41d65a0bd66? Including the CVE fixes?

Quck update: the older version seems to be based of https://github.com/projectatomic/runc/commit/9c3c5f853ebf0ffac0d087e94daef462133b69c7

Seems like the package switched from the 1.3.1-rhel branch to master?

I guess this will get fixed after it's fixed in RHEL. I don't control the CentOS package, setting assignee to JohnnyHughes

Maybe it's just that version -109 is not build for centos?
