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
