If the container unexpectedly exists we may need to restore physical

network: fix LXC_NET_NONE cleanup · 92bc7090

authored Dec 02, 2020

We have a case where we have a nested container with LXC_NET_NONE run
inside a container that's *also* got no network namespace (run by
lxc-usernsexec).

The "am I root" check in this function then does not suffice, since the
euid of the task is 0 but it does not have privilege over its network
namespace, and thus cannot do any of the restore operations:

lxc foo 20201201232059.271 TRACE network - network.c:lxc_restore_phys_nics_to_netns:3299 - Moving physical network devices back to parent network namespace
lxc foo 20201201232059.271 ERROR network - network.c:lxc_restore_phys_nics_to_netns:3307 - Operation not permitted - Failed to enter network namespace
lxc foo 20201201232059.271 ERROR start - start.c:__lxc_start:2045 - Failed to move physical network devices back to parent network namespace

Let's check that we indeed did clone the network namespace, and thus have
things to restore to their correct namespace before attempting to actually
restore them.

I suspect it's possible we can also get rid of some of the network namespace
preservation stuff in start.c in the LXC_NET_NONE case.

file_utils: fix config file parsing · 1c7c31b5

authored Nov 17, 2020

We accidently used the "bytes_to_write" variable after we've written all the
bytes at which point it is guaranteed to be 0. Let's use the "bytes_read"
variable instead.
