/* General locking concepts:
|
||||
* The goal of our locking is to of course provide
|
||||
* consistency and yet minimize overhead. We will
|
||||
* attempt to use non-recursive locks which are supposed
|
||||
* to be quite inexpensive. Now in order to do this the goal
|
||||
* is that most functions are not aware of locking. Once we
|
||||
* have a TCB we lock it and unlock when we are through. This
|
||||
* means that the TCB lock is kind-of a "global" lock when
|
||||
* working on an association. Caution must be used when
|
||||
* asserting a TCB_LOCK since if we recurse we deadlock.
|
||||
*
|
||||
* Most other locks (INP and INFO) attempt to localize
|
||||
* the locking i.e. we try to contain the lock and
|
||||
* unlock within the function that needs to lock it. This
|
||||
* sometimes mean we do extra locks and unlocks and loose
|
||||
* a bit of efficency, but if the performance statements about
|
||||
* non-recursive locks are true this should not be a problem.
|
||||
* One issue that arises with this only lock when needed
|
||||
* is that if an implicit association setup is done we
|
||||
* have a problem. If at the time I lookup an association
|
||||
* I have NULL in the tcb return, by the time I call to
|
||||
* create the association some other processor could
|
||||
* have created it. This is what the CREATE lock on
|
||||
* the endpoint. Places where we will be implicitly
|
||||
* creating the association OR just creating an association
|
||||
* (the connect call) will assert the CREATE_INP lock. This
|
||||
* will assure us that during all the lookup of INP and INFO
|
||||
* if another creator is also locking/looking up we can
|
||||
* gate the two to synchronize. So the CREATE_INP lock is
|
||||
* also another one we must use extreme caution in locking
|
||||
* to make sure we don't hit a re-entrancy issue.
|
||||
*
|
||||
* For non FreeBSD 5.x and above we provide a bunch
|
||||
* of EMPTY lock macro's so we can blatantly put locks
|
||||
* everywhere and they reduce to nothing on NetBSD/OpenBSD
|
||||
* and FreeBSD 4.x
|
||||
*
|
||||
*/
|
||||
|
||||
|
||||
/* When working with the global SCTP lists we lock and unlock
|
||||
* the INP_INFO lock. So when we go to lookup an association
|
||||
* we will want to do a SCTP_INP_INFO_RLOCK() and then when
|
||||
* we want to add a new association to the sctppcbinfo list's
|
||||
* we will do a SCTP_INP_INFO_WLOCK().
|
||||
*/
|
||||
|
||||
/*
|
||||
* FIX ME, all locks right now have a
|
||||
* recursive check/panic to validate that I
|
||||
* don't have any lock recursion going on.
