Subject: Does rtnl_lock inhibit incoming traffic?
Date: Wed, 29 May 2013 21:08:29 +0200 [thread overview]
Message-ID: <51A6522D.2000008@hartkopp.net> (raw)
Hello,
AFAIK the rtnl_lock is used (at least) to protect the configuration of
netdevices and routing tables.
Is the reception of incoming traffic inhibited while the rtnl_lock is set, or
would i need to protect the data structures to be modified with an additional
spinlock_bh() / write_lock_bh()?
Like this one here:

Oliver
