[Devel] [PATCH v3 0/9] Upstream Linux support for userns

[Glauber Costa]

Kir,

Please review the following patchset. The main difference from last version is that
we support running with userns disabled even if it is present. This effectively means
that containers that were already created and owned by root will keep working. It is
also possible to explicitly disable it at container creation by setting local_uid to 0.

There are also some bugfixes and changes according to the review you provided.

Running a container works, and "vzctl enter" works as well. Most pressing, is
the fact that although this patchset finally implements --ipadd (now all
infrastructure is in place).

Glauber Costa (9):
  host uid and gid parameters
  adjust fs_create parameter
  pass parameters to open
  user namespace support for upstream containers
  add user mismatch test
  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.
