Convert IIJ copyrights to BSD copyrights. Approved by: Toshiharu OHNO <tohno@sirius.ocn.ne.jp>

various: general adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

Make the code format more in line with style(9). Update loadalias to use the new libalias api. Update to version 1.1.

o Move struct lcp and struct ccp into struct link. o Remove bundle2lcp(), bundle2ccp() and bundle2link(). They're too resource-hungry and we have `owner pointers' to do their job. o Make our FSM understand LCPs that are always ST_OPENED (with a minimum code that != 1). o Send FSM code rejects for invalid codes. o Make our bundle fsm_parent deal with multiple links. o Make timer diagnostics pretty and allow access via ~t in `term' mode (not just when logging debug) and `show timers'. Only show timers every second in debug mode, otherwise we get too many diagnostics to be useful (we probably still do). Also, don't restrict ~m in term mode to depend on debug logging. o Rationalise our bundles' phases. o Create struct mp (multilink protocol). This is both an NCP and a type of struct link. It feeds off other NCPs for output, passing fragmented packets into the queues of available datalinks. It also gets PROTO_MP input, reassembles the fragments into ppp frames, and passes them back to the HDLC layer that the fragments were passed from. ** It's not yet possible to enter multilink mode :-( ** o Add `set weight' (requires context) for deciding on a links weighting in multilink mode. Weighting is simplistic (and probably badly implemented) for now. o Remove the function pointers in struct link. They ended up only applying to physical links. o Configure our tun device with an MTU equal to the MRU from struct mp's LCP and a speed equal to the sum of our link speeds. o `show {lcp,ccp,proto}' and `set deflate' now have optional context and use ChooseLink() to decide on which `struct link' to use. This allows behaviour as before when in non-multilink mode, and allows access to the MP logical link in multilink mode. o Ignore reconnect and redial values when in -direct mode and when cleaning up. Always redial when in -ddial or -dedicated mode (unless cleaning up). o Tell our links to `staydown' when we close them due to a signal. o Remove remaining `#ifdef SIGALRM's (ppp doesn't function without alarms). o Don't bother strdup()ing our physical link name. o Various other cosmetic changes.

#define PROTO_MP 0x003d /* Multilink fragment */
o Add ipv6 support, abstracting most NCP addresses into opaque 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>

o Activate link-level CCPs in multilink mode, by bringing them into the ST_STOPPED state. o Allow an optional ccp|lcp argument to `down'. The default is still lcp (as before). You can now call down with no context in multilink mode, in which case it'll down the multilink ccp or the entire bundle (*very* rude). o Allow an optional `!' after `close ccp' (close ccp!) to tell ccp to stay in the CLOSED state after the terminate ACK. The default is now to re-enter STOPPED so that the peer can bring the layer back up if desired. o Always handle proto-compressed packets, even if we've agreed (in LCP) that the peer will not send us 1 byte protocols. If the peer violates the LCP agreement, log it to the HDLC log. o Fix some comments.

o Redesign the layering mechanism and make the aliasing code part of 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''.
