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.
o Bump version number to 3.0.4
o When talking to a RADIUS server, provide a NAS-Port-Type.
When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal
to the SESSIONID from the environment in direct mode or the
NGM_PPPOE_SESSIONID message in other modes. If no SESSIONID is found,
default to the interface index in client mode or zero in server mode.
When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number
of the physical device (ie, the N in /dev/i4brbchN).
This makes it easier for the RADIUS server to identify the client
WRT accounting data etc.

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

Allow ``set server open'' to re-open the diagnostic socket.
Handle SIGUSR1 by re-opening the diagnostic socket
When receiving SIGUSR2 (and in ``set server none''), don't forget the
socket details so that ``set server open'' and SIGUSR1 open it again.
Don't create the diagnostic socket as uid 0 ! It's far to dangerous.
o If a prompt is executing the command, only display the warning to
that prompt
o If a prompt is executing a ``load'' command, display the warning
to all prompts *and* syslog
o Otherwise, display the warning to all prompts *and* syslog.
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''.
with more than one read(). When we detect one, don't
forget to pass it to async_Input() and drop our
terminal back into command mode.
Don't output an extraneous \r if we're passed \r\n
to prompt_vprintf in raw mode.
details. Compiling with -DNORADIUS (the default for `release')
removes support.
TODO: The functionality in libradius::rad_send_request() needs
to be supplied as a set of routines so that ppp doesn't
have to wait indefinitely for the radius server(s). Instead,
we need to get a descriptor back, select() on the descriptor,
and ask libradius to service it when necessary.
For now, ppp blocks SIGALRM while in rad_send_request(), so
it misses PAP/CHAP retries & timeouts if they occur.
Only PAP is functional. When CHAP is attempted, libradius
complains that no User-Password has been specified... rfc2138
says that it *mustn't* be used for CHAP :-(

the device is successfully opened. If we fail to open it,
mention the fact.
Also go back into command mode as soon as the device is closed
rather than waiting for the user to type something before noticing.
(see the new ``set callback'' and ``set cbcp'' commands)
o Add a ``cbcp'' log level and mbuf type.
o Don't dump core when \T is given in ``set login'' or
``set hangup''.
o Allow ``*'' and blanks as placeholders in ppp.secret and
allow a fifth field for specifying auth/cbcp dialback
parameters.
o Remove a few extraneous #includes
o Define the default number of REQs (restart counter) in defs.h
rather than hardcoding ``5'' all over the place.
o Fix a few man page inconsistencies.
end up writing zero bytes, sleep for 1/10 of a second so that
we don't end up using up too much cpu.
This should only ever happen on systems that wrongly report a
descriptor as writable despite the tty buffer being full.
Discussed with: Jeff Evarts
o Do an initial run-time check to see if select() alters the passed
timeval. This knowledge isn't yet used, but will be soon.
o Always put a '\r' before a '\n' at the end of a line
in prompt_vPrintf() in term mode, and make prompt_Printf()
use prompt_vPrintf().
o Fix ~? message.
o Bring the static ``ttystate'' into struct prompt so that
the tilde context is per prompt and not global.
o Comment the remaining static variables so that it's
clear why they're static.
o Add some XXX comments suggesting that our interface list
and our hostname should be re-generated after a signal
(say SIGUSR1) so that a machine with PCCARDs has a chance.
It's now dealt with by the `server' object. This simplifies
things as we only have one list of prompt descriptors and
the log_ routines check prompt::logactive to determine
whether it should be used for output.
o Include the MP socket UpdateSet() result in bundle::UpdateSet().
o Don't select on the tun device unless we're in NETWORK
phase or AUTO mode.
o Stop the idle timer when we go to DEAD phase. We may
have transferred a link and not had a chance to kill
it.
o Don't fail when trying to unlink our transferred datalink
from our descriptor lists just before the transfer.
o Add our link descriptor to the write set if we got a short
write the last time (physical::out is set).
o Log the connection source address when a connection is closed.
o Remove descriptor::next field. Descriptor lists are not required
any more.
o Log FD_SET()s in LogTIMER.
o Identify the descriptor that causes an EBADF from select()
if LogTIMER is enabled (then exit).
o Call the MP server UpdateSet() function after calling
the UpdateSet() for all links - the link may enter
PHASE_TERMINATE and bring down the MP server - breaking
the imminent select().
o Shuffle things that live at the datalink level into
``show link'' rather than ``show modem''.
o Make both ``show'' commands prettier and more consistent,
and display carrier status, link type and our name in
``show modem''.
o Show redial and reconnect information in ``show link''
and remove ``show redial'' and ``show reconnect''.
o Down the correct link in bundle_LinkLost().
o Remove stale -direct and -background links at the end
of our main loop, not when we know they're going. This
prevents unexpected pointer-invalidations...
o If we ``set server'' with the same values twice, notice
and don't moan about failure.
o Record dial script despite our link mode. The mode may
be changed later (next mod) :-) We never run scripts
in -direct and -dedicated modes.
o Make ``set server none'' functional again.
o Correct datalink state array so that we don't report an
``unknown'' state.
o Pass struct ipcp to IpcpCleanInterface, not struct fsm.
o Create TUN_PREFIX define rather than hard-coding in main.c
o prompt_TtyInit now handles a NULL prompt for -direct mode
rather than having to create one then destroy it uncleanly.
o Mention our mode in the "PPP Started" LogPHASE message.
o Bring all auto links up when we have something to send.
o Remove some redundant Physical_*() functions.
o Show which connection is running a command when logging
commands.
o Initialise throughput uptime correctly.
SIGTTIN or SIGTTOU, we just disable use of the prompt
for the controlling terminal (and put a ^Z next to it
in a ``show who'' listing).
Unfortunately, we need to enable a timer to ``poll''
for the terminal having us as the controlling pgrp
when a user does a ``bg''. If anyone knows how to
do this better - please speak up (is there any
indication to the process group leader when it's
ctrling terminal gets tcsetpgrp()'d back ?)....
option. We never ask a client for MSChap when we've got
chap `enabled', and we dynamically answer using MSChap
if the peer demands it.
o Remove all of the bundle2*() series of functions except
bundle2datalink() as they're too expensive. The only
calls to bundle2datalink() are made from command.c when
determining context.
o Write to the correct modem in term mode, and check the
return value, dropping back to command mode if the write
fails.
Cosmetic:
Make the PPP COMMAND LIST section of the man page
prettier, better and more consistent. Alphabeticalise
all command lists and document missing commands.
o Our diagnostic socket has its password set in the `set socket'
line only (not in ppp.secret).
o Passwords are per server socket (*VarAuthKey are gone)
o Authority is per prompt (VarLocalAuth is gone).
o Local logging is per prompt.
o Add a `show who' command to see who's connected. No identd
routine - just a `where the connection came from' display.
o SIGUSR1 is disabled for now - we have no way of choosing a
password for the socket created :-(
Prompts are attached as a list of `struct descriptor's in
struct bundle, and serviced under the bundles descriptor
service routines. Ultimately, everything should be done
like this.
Cosmetic:
o alphabeticalise SRCS in Makefile.
o Add a few comments in command.h
TODO: Start checking that we don't overflow the descriptor sets
in select() now that we can have any number of descriptors.
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.
