* Back out my lats commit of locking down a socket, it conflicts with hsu's work.tanimura2002-05-311-12/+0

* Lock down a socket, milestone 1.tanimura2002-05-201-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a socket buffer. The mutex in the receive buffer also protects the data in struct socket. o Determine the lock strategy for each members in struct socket. o Lock down the following members: - so_count - so_options - so_linger - so_state o Remove *_locked() socket APIs. Make the following socket APIs touching the members above now require a locked socket: - sodisconnect() - soisconnected() - soisconnecting() - soisdisconnected() - soisdisconnecting() - sofree() - soref() - sorele() - sorwakeup() - sotryfree() - sowakeup() - sowwakeup() Reviewed by: alfred
* Revert the change of #includes in sys/filedesc.h and sys/socketvar.h.tanimura2002-04-301-4/+7
| | | | | | | | | | Requested by: bde Since locking sigio_lock is usually followed by calling pgsigio(), move the declaration of sigio_lock and the definitions of SIGIO_*() to sys/signalvar.h. While I am here, sort include files alphabetically, where possible.

* Give struct socket structures a ref counting interface similar todillon2001-11-171-2/+2
| | | | | | | vnodes. This will hopefully serve as a base from which we can expand the MP code. We currently do not attempt to obtain any mutex or SX locks, but the door is open to add them when we nail down exactly how that part of it is going to work.
* Change a couple of M_WAITOKs used in M_PREPEND() to M_TRYWAITs, whichbmilekic2001-04-051-2/+2
| | | | | | is what they should be. As the returned mbuf is already checked for failure of M_PREPEND even in the wait case, nothing more to be done here.

* Lock down the network interface queues. The queue mutex must be obtainedjlemon2000-11-251-0/+2
| | | | | | | | | | | | | | 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.

* Examine all occurrences of sprintf(), strcat(), and str[n]cpy()archie1998-12-041-4/+4
| | | | | | | | | | | | | | for possible buffer overflow problems. Replaced most sprintf()'s with snprintf(); for others cases, added terminating NUL bytes where appropriate, replaced constants like "16" with sizeof(), etc. These changes include several bug fixes, but most changes are for maintainability's sake. Any instance where it wasn't "immediately obvious" that a buffer overflow could not occur was made safer.
