[PATCH V2 0/3] some fixes of tuntap

[Jason Wang]

Hi all:

There series fixes two issues:
- Don't allow calling TUNSETIFF when a file is detached which may cause kernel
data structure corrupt.
- Fix the reference count leaking of sock and module.

Plus a suggestion from Eric to use rtnl_dereference() instead of the open code.

Changes from v1:
- don't use rcu to dereference tfile->detached as it was already protected by
rtnl lock.
- add a patch of switching to use rtnl_dereference().

Jason Wang (3):
  tuntap: switch to use rtnl_dereference()
  tuntap: forbid calling TUNSETIFF when detached
  tuntap: fix leaking reference count
