* * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.Bosko Milekic2000-12-211-2/+2
| | | | | | | | | | | | | | | | | | | | | 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(). Made it pass M_WAITOK instead. If we were ever to redefine the value of the M_WAIT flag, this could have became a big problem. Notes: svn path=/head/; revision=70254

* Lock down the network interface queues. The queue mutex must be obtainedJonathan Lemon2000-11-251-31/+7
| | | | | | | | | | | | | | | | | 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.

* Make the ng_ether(4) node type dynamically loadable like the rest.Archie Cobbs2000-06-261-422/+96
| | | | | | | | | | | | | | | | This means 'options NETGRAPH' is no longer necessary in order to get netgraph-enabled Ethernet interfaces. This supports loading/unloading the ng_ether.ko and attaching/detaching the Ethernet interface in any order. Add two new hooks 'upper' and 'lower' to allow access to the protocol demux engine and the raw device, respectively. This enables bridging to be defined as a netgraph node, if so desired.

The good news: net result of 1016 lines removed, and this should make bridging now work with *all* Ethernet drivers. The bad news: it's nearly impossible to test every driver, especially for bridging, and I was unable to get much testing help on the mailing lists.

| | | | | | | | | | | | | | | | | | | | | | | | | | NGM_BINARY2ASCII, which convert control messages to ASCII and back. This allows control messages to be sent and received in ASCII form using ngctl(8), which makes ngctl a lot more useful. This also allows all the type-specific debugging code in libnetgraph to go away -- instead, we just ask the node itself to do the ASCII translation for us. Currently, all generic control messages are supported, as well as messages associated with the following node types: async, cisco, ksocket, and ppp. See /usr/share/examples/netgraph/ngctl for an example of using this. Also give ngctl(8) the ability to print out incoming data and control messages at any time. Eventually nghook(8) may be subsumed. Several other misc. bug fixes.
