Subject: [PATCH V2 0/3] some fixes of tuntap
Date: Sat, 12 Jan 2013 10:59:31 +0800 [thread overview]
Message-ID: <1357959574-13113-1-git-send-email-jasowang@redhat.com> (raw)
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
