From 954e1d2ccdb661d5c8b7f69340d118fa7ba7fb85 Mon Sep 17 00:00:00 2001 From: jlemon Date: Sat, 25 Nov 2000 07:35:38 +0000 Subject: Lock down the network interface queues. The queue mutex must be obtained 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. --- sys/netatalk/ddp_usrreq.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'sys/netatalk/ddp_usrreq.c') diff --git a/sys/netatalk/ddp_usrreq.c b/sys/netatalk/ddp_usrreq.c index 167c0b3..617ab29 100644 --- a/sys/netatalk/ddp_usrreq.c +++ b/sys/netatalk/ddp_usrreq.c @@ -548,6 +548,8 @@ ddp_init(void ) { atintrq1.ifq_maxlen = IFQ_MAXLEN; atintrq2.ifq_maxlen = IFQ_MAXLEN; + mtx_init(&atintrq1.ifq_mtx, "at1_inq", MTX_DEF); + mtx_init(&atintrq2.ifq_mtx, "at2_inq", MTX_DEF); } #if 0 -- cgit v1.1
