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.

* Redo the sigio locking.alfred2002-05-011-5/+0
| | | | | | | | | | | Turn the sigio sx into a mutex. Sigio lock is really only needed to protect interrupts from dereferencing the sigio pointer in an object when the sigio itself is being destroyed. In order to do this in the most unintrusive manner change pgsigio's sigio * argument into a **, that way we can lock internally to the function.
* Revert the change of #includes in sys/filedesc.h and sys/socketvar.h.tanimura2002-04-301-1/+3
| | | | | | | | | | 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.
* Add a global sx sigio_lock to protect the pointer to the sigio objecttanimura2002-04-271-1/+3
| | | | | | | | | | of a socket. This avoids lock order reversal caused by locking a process in pgsigio(). sowakeup() and the callers of it (sowwakeup, soisconnected, etc.) now require sigio_lock to be locked. Provide sowwakeup_locked(), soisconnected_locked(), and so on in case where we have to modify a socket and wake up a process atomically.

* Lock struct pgrp, session and sigio.tanimura2002-02-231-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | New locks are: - pgrpsess_lock which locks the whole pgrps and sessions, - pg_mtx which protects the pgrp members, and - s_mtx which protects the session members. Please refer to sys/proc.h for the coverage of these locks. Changes on the pgrp/session interface: - pgfind() needs the pgrpsess_lock held. - The caller of enterpgrp() is responsible to allocate a new pgrp and session. - Call enterthispgrp() in order to enter an existing pgrp. - pgsignal() requires a pgrp lock held.

* Replace the mbuf external reference counting code with somethingdwmalone2000-08-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that should be better. The old code counted references to mbuf clusters by using the offset of the cluster from the start of memory allocated for mbufs and clusters as an index into an array of chars, which did the reference counting. If the external storage was not a cluster then reference counting had to be done by the code using that external storage. NetBSD's system of linked lists of mbufs was cosidered, but Alfred felt it would have locking issues when the kernel was made more SMP friendly. The system implimented uses a pool of unions to track external storage. The union contains an int for counting the references and a pointer for forming a free list. The reference counts are incremented and decremented atomically and so should be SMP friendly. This system can track reference counts for any sort of external storage. Access to the reference counting stuff is now through macros defined in mbuf.h, so it should be easier to make changes to the system in the future. The possibility of storing the reference count in one of the referencing mbufs was considered, but was rejected 'cos it would often leave extra mbufs allocated. Storing the reference count in the cluster was also considered, but because the external storage may not be a cluster this isn't an option. The size of the pool of reference counters is available in the stats provided by "netstat -m".
