Subject: [PATCH] Remove tun/tap from the default device rules
Looking through git blame, this was added by commit 9fac18329
aka "Initial commit of runc binary", most probably by mistake.
Obviously, a container should not have access to tun/tap device, unless
it is explicitly specified in configuration.
Now, removing this might create a compatibility issue, but I see no
other choice.
Aside from the obvious misconfiguration, this should also fix the
annoying

messages from systemd on every container start, when runc uses systemd
cgroup driver, and the system runs an old (< v240) version of systemd
(the message was presumably eliminated by [1]).

Subject: [PATCH] libct: fix mounting via wrong proc fd
Due to a bug in commit 9c444070ec7, when the user and mount namespaces
are used, and the bind mount is followed by the cgroup mount in the
spec, the cgroup is mounted using the bind mount's mount fd.
This can be reproduced with podman 4.1 (when configured to use runc):
$ podman run --uidmap 0:100:10000 quay.io/libpod/testimage:20210610 mount
Error: /home/kir/git/runc/runc: runc create failed: unable to start container process: error during container init: error mounting "cgroup" to rootfs at "/sys/fs/cgroup": mount /proc/self/fd/11:/sys/fs/cgroup/systemd (via /proc/self/fd/12), flags: 0x20502f: operation not permitted: OCI permission denied
or manually with the spec mounts containing something like this:
{
"destination": "/etc/resolv.conf",
"type": "bind",
"source": "/userdata/resolv.conf",
"options": [
"bind"
]
},
{
"destination": "/sys/fs/cgroup",
"type": "cgroup",
"source": "cgroup",
"options": [
"rprivate",
"nosuid",
"noexec",
"nodev",
"relatime",
"ro"
]
}
The issue was not found earlier since it requires using userns, and even then
mount fd is ignored by mountToRootfs, except for bind mounts, and all the bind
mounts have mountfd set, except for the case of cgroup v1's /sys/fs/cgroup
which is internally transformed into a bunch of bind mounts.
This is a minimal fix for the issue, suitable for backporting.
Fixes: 9c444070ec7 ("Open bind mount sources from the host userns")
