Note that, rcu_assign_pointer() and rcu_dereference() relate to
SRCU just as they do to other forms of RCU.

15. The whole point of call_rcu(), synchronize_rcu(), and friends
is to wait until all pre-existing readers have finished before
carrying out some otherwise-destructive operation. It is
therefore critically important to -first- remove any path
that readers can follow that could be affected by the
destructive operation, and -only- -then- invoke call_rcu(),
synchronize_rcu(), or friends.

Because these primitives only wait for pre-existing readers,
it is the caller's responsibility to guarantee safety to
any subsequent readers.

Smack Netlabel Exceptions

You will often find that your labeled application has to talk to the outside,
unlabeled world. To do this there's a special file /smack/netlabel where you can
add some exceptions in the form of :
@IP1 LABEL1 or
@IP2/MASK LABEL2

It means that your application will have unlabeled access to @IP1 if it has
write access on LABEL1, and access to the subnet @IP2/MASK if it has write
access on LABEL2.

Entries in the /smack/netlabel file are matched by longest mask first, like in
classless IPv4 routing.

A special label '@' and an option '-CIPSO' can be used there :
@ means Internet, any application with any label has access to it
-CIPSO means standard CIPSO networking

If you don't know what CIPSO is and don't plan to use it, you can just do :
echo 127.0.0.1 -CIPSO > /smack/netlabel
echo 0.0.0.0/0 @ > /smack/netlabel

If you use CIPSO on your 192.168.0.0/16 local network and need also unlabeled
Internet access, you can have :
echo 127.0.0.1 -CIPSO > /smack/netlabel
echo 192.168.0.0/16 -CIPSO > /smack/netlabel
echo 0.0.0.0/0 @ > /smack/netlabel
