[Devel] [PATCH v4 0/7] User namespace support for upstream containers

[Glauber Costa]

Kir,

In this patchset, I hope to be addressing all your concerns. It is a bit
massive code, so if is there still anything that you would me to change,
don't shy away. I will go back to it ASAP.

That said, I am incorporating your comments on the previous PATCH 4 (now 1),
and adding another one, that also passes cmd_p to open. This is being sent as
an incremental patch since you said you have already merged up to PATCH 3 (I
still don't see that in git). But if you haven't feel free to fold it.

With this patch, we are fully able to get rid of the default value during
create, and yet test for userns presence very early during creation time. I
think this very much clarifies our handling of the command line option. The
documentation is also changed as you requested, for consistency.

Glauber Costa (7):
  user namespace support for upstream containers
  add user mismatch test
  Also pass cmd_p pointer to container open
  allow local uid and gid to be specified at container creation
  modify tar extraction to account for user namespace
  automatically add bridge venet0 when needed
  allow for distro-specific fix ups at creation time.
