* The socket field so_state is used to hold a variety of socket relatedRobert Watson2004-06-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flags relating to several aspects of socket functionality. This change breaks out several bits relating to send and receive operation into a new per-socket buffer field, sb_state, in order to facilitate locking. This is required because, in order to provide more granular locking of sockets, different state fields have different locking properties. The following fields are moved to sb_state: SS_CANTRCVMORE (so_state) SS_CANTSENDMORE (so_state) SS_RCVATMARK (so_state) Rename respectively to: SBS_CANTRCVMORE (so_rcv.sb_state) SBS_CANTSENDMORE (so_snd.sb_state) SBS_RCVATMARK (so_rcv.sb_state) This facilitates locking by isolating fields to be located with other identically locked fields, and permits greater granularity in socket locking by avoiding storing fields with different locking semantics in the same short (avoiding locking conflicts). In the future, we may wish to coallesce sb_state and sb_flags; for the time being I leave them separate and there is no additional memory overhead due to the packing/alignment of shorts in the socket buffer structure.

* Introduce a MAC label reference in 'struct inpcb', which cachesRobert Watson2003-11-182-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.Bosko Milekic2000-12-211-1/+1
| | | | | | | | | | | | | | | | | | | | | This is because calls with M_WAIT (now M_TRYWAIT) may not wait forever when nothing is available for allocation, and may end up returning NULL. Hopefully we now communicate more of the right thing to developers and make it very clear that it's necessary to check whether calls with M_(TRY)WAIT also resulted in a failed allocation. M_TRYWAIT basically means "try harder, block if necessary, but don't necessarily wait forever." The time spent blocking is tunable with the kern.ipc.mbuf_wait sysctl. M_WAIT is now deprecated but still defined for the next little while. * Fix a typo in a comment in mbuf.h * Fix some code that was actually passing the mbuf subsystem's M_WAIT to malloc().

* Lock down the network interface queues. The queue mutex must be obtainedJonathan Lemon2000-11-252-10/+3
| | | | | | | | | | | | | | | | | before adding/removing packets from the queue. Also, the if_obytes and if_omcasts fields should only be manipulated under protection of the mutex. IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on the queue. An IF_LOCK macro is provided, as well as the old (mutex-less) versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which needs them, but their use is discouraged. Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF, which takes care of locking/enqueue, and also statistics updating/start if necessary.
