* Add a radius_Flush() function that waits for the response (or timeout) toBrian Somers2005-01-271-0/+1
| | | | | | | | | | | | | | | | | any pending RADIUS transaction. Use this before sending RAD_STOP RADIUS messages so that we definitely ``stop'' the session. It was discovered that sometimes when the link timed out, we got lucky enough to have an un-ACK'd RADIUS accounting transaction in progress, resulting in the RAD_STOP message failing to send.

Logging of RADIUS accounting information moves to a ``set log [+-]radius'' level, along with the RADIUS alive info, and the version number is bumped to 3.2 to reflect this.

* o Add ipv6 support, abstracting most NCP addresses into opaqueBrian Somers2001-08-141-324/+275
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | structures (well, they're treated as opaque). It's now possible to manage IPv6 interface addresses and routing table entries and to filter IPV6 traffic whether encapsulated or not. IPV6CP support is crude for now, and hasn't been tested against any other implementations. RADIUS and IPv6 are independent of eachother for now. ppp.linkup/ppp.linkdown aren't currently used by IPV6CP o Understand all protocols(5) in filter rules rather than only a select few. o Allow a mask specification for the ``delete'' command. It's now possible to specifically delete one of two conflicting routes. o When creating and deleting proxy arp entries, do it for all IPv4 interface addresses rather than doing it just for the ``current'' peer address. o When iface-alias isn't in effect, don't blow away manually (via ``iface add'') added interface addresses. o When listening on a tcp server (diagnostic) socket, bind so that a tcp46 socket is created -- allowing both IPv4 and IPv6 connections. o When displaying ICMP traffic, don't display the icmp type twice. When display traffic, display at least some information about unrecognised traffic. o Bump version Inspired after filtering work by: Makoto MATSUSHITA <matusita@jp.FreeBSD.org> Notes: svn path=/head/; revision=81634

* Introduce a forth IP packet queue. Urgent packets withBrian Somers1999-09-071-43/+68
| | | | | | | | | | | | ip_tos == IPTOS_LOWDELAY now get precidence over urgent packets with ip_tos != IPTOS_LOWDELAY and non-urgent packets with ip_tos == IPTOS_LOWDELAY. Enhance the ``set urgent'' syntax to allow for urgent UDP packets as well as urgent TCP packets. Notes: svn path=/head/; revision=51048
* o Split the two IPCP queues into three - one for FSM dataBrian Somers1999-09-041-1/+112
| | | | | | | | | | | | | | | (LCP/CCP/IPCP), one for urgent IP traffic and one for everything else. o Add the ``set urgent'' command for adjusting the list of urgent port numbers. The default urgent ports are 21, 22, 23, 513, 514, 543 and 544 (Ports 80 and 81 have been removed from the default priority list). o Increase the buffered packet threshold from 20 to 30. o Report the number of packets in the IP output queue and the list of urgent ports under ``show ipcp''.

* o Add the -foreground switch. This switch behaves like -background exceptBrian Somers1999-08-191-4/+4
| | | | | | | | | | | | that ppp stays in the foreground. o Add the -quiet switch to quieten ppps startup o Add the -nat flag and discourage the use of the -alias flag. Both do the same thing. o Correct some nat usage strings. o Change the internal ``alias'' command to ``nat''. Notes: svn path=/head/; revision=50059
* o Obsolete the undocumented ``set weight'' command.Brian Somers1999-08-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | o If we're using RADIUS and the RADIUS mtu is less than our peers mru/mrru, reduce our mtu to this value for NetBSD too. o Make struct throughput's sample period dynamic and tweak the ppp version number to reflect the extra stuff being passed through the local domain socket as a result (MP mode). o Measure the current throughput based on the number of samples actually taken rather than on the full sample period. o Keep the throughput statisics persistent while being passed to another ppp invocation through the local domain socket. o When showing throughput statistics after the timer has stopped, use the stopped time for overall calculations, not the current time. Also show the stopped time and how long the current throughput has been sampled for. o Use time() consistently in throughput.c o Tighten up the ``show bundle'' output. o Introduce the ``set bandwidth'' command. o Rewrite the ``set autoload'' command. It now takes three arguments and works based on a rolling bundle throughput average compared against the theoretical bundle bandwidth over a given period (read: it's now functional).

* o Alter the mbuf type as it's processed by different layers.Brian Somers1999-06-021-3/+5
| | | | | | | | | | | o Show more information about missing MP fragments in ``show mp''. o Do away with mbuf_Log(). It was showing mbuf stats twice on receipt of LCP/CCP/IPCP packets.... ???!!? o Pre-allocate a bit extra when creating LQR packets to avoid having to allocate another mbuf in mbuf_Prepend(). Notes: svn path=/head/; revision=47695

* Deal with the fact that as we now mbuf_Read the fsmBrian Somers1999-05-091-2/+2
| | | | | | | | | | | | header in fsm_Input() we often end up with a NULL mbuf. Deal with a possible NULL mbuf being passed into mbuf_Prepend(). Adjust some spacing to make things more consistent. Notes: svn path=/head/; revision=46828
* o Redesign the layering mechanism and make the aliasing code part ofBrian Somers1999-05-081-19/+12
| | | | | | | | | | | | | | | | | | | | | | | | the layering. We now ``stack'' layers as soon as we open the device (when we figure out what we're dealing with). A static set of `dispatch' routines are also declared for dealing with incoming packets after they've been `pulled' up through the stacked layers. Physical devices are now assigned handlers based on the device type when they're opened. For the moment there are three device types; ttys, execs and tcps. o Increment version number to 2.2 o Make an entry in [uw]tmp for non-tty -direct invocations (after pap/chap authentication). o Make throughput counters quad_t's o Account for the absolute number of mbuf malloc()s and free()s in ``show mem''. o ``show modem'' becomes ``show physical''.
