Introduce a MAC label reference in 'struct inpcb', which caches

2003-11-18T00:39:07Z

the MAC label referenced from 'struct socket' in the IPv4 and IPv6-based protocols. This permits MAC labels to be checked during network delivery operations without dereferencing inp->inp_socket to get to so->so_label, which will eventually avoid our having to grab the socket lock during delivery at the network layer. This change introduces 'struct inpcb' as a labeled object to the MAC Framework, along with the normal circus of entry points: initialization, creation from socket, destruction, as well as a delivery access control check. For most policies, the inpcb label will simply be a cache of the socket label, so a new protocol switch method is introduced, pr_sosetlabel() to notify protocols that the socket layer label has been updated so that the cache can be updated while holding appropriate locks. Most protocols implement this using pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use the the worker function in_pcbsosetlabel(), which calls into the MAC Framework to perform a cache update. Biba, LOMAC, and MLS implement these entry points, as do the stub policy, and test policy.

Replace the if_name and if_unit members of struct ifnet with new members

2003-10-31T18:32:15Z

if_xname, if_dname, and if_dunit. if_xname is the name of the interface and if_dname/unit are the driver name and instance. This change paves the way for interface renaming and enhanced pseudo device creation and configuration symantics.

Update netisr handling; Each SWI now registers its queue, and all queue

drain routines are done by swi_net, which allows for better queue control at some future point. Packets may also be directly dispatched to a netisr instead of queued, this may be of interest at some installations, but currently defaults to off.
