Don't mention the authors name at startup. He's already credited
in the man page. Instead, make the message consistent with the
one given to the diagnostic port (and fix the grammar when entering
`term' mode).
Don't credit the zlib author in the man page as ppp isn't linked
directly with zlib (it's shared).
Mention when the OpenBSD port was first made available.
The delay defaults to 1 sec (as it always has) unless we've done
a ~p in interactive mode or we've actually detected a HDLC frame.
This is now cleanly implemented (via async timers) so that it is
possible for LCP to come up despite the delay if an LCP REQ is
received.
This will hopefully solve situations with slow servers or slirp
scenarios (where ECHO is left on the port for a second or so before
the peer enters packet mode).
Also, ~p in interactive mode no longer changes the value of the default
openmode delay and -dedicated mode enters packet mode in the right state
according to the value of openmode.
o Allow a forth argument in ppp.secret, specifying a new
label. This gives control over which section of
ppp.link{up,down} is used based on the authenticated user.
o Support random address ranges in ppp.secret (not just in ppp.conf).
o Add a AUTHENTICATING INCOMING CONNECTIONS section to the man page.
o Add a bit more about DEFLATE in the man page.
o Fix the incorrect "you must specify a password in interactive
mode" bit of the manual.
o Space things in the man page consistently.
o Be more precice about where you can use MYADDR, HISADDR and INTERFACE
in the "add" command documentation.
interactive mode.
Use `netfd' in fcntl() and tc[gs]etattr() calls rather than
the hard coded descriptor 0.
Use _FILENO constants from unistd.h
This un-breaks things after my recent `close(0)' in interactive
mode.
Close STDIN_FILENO, and open _PATH_TTY O_RDONLY as `netfd'. This
has the effect of allowing `show route' to output more than about
a page of data (on FreeBSD, not OpenBSD....). I have no idea why,
except that it was a direct consequence of the tcsetattr() in
TtyCommandMode(). My previous fix (closing descriptor 0) `fixed'
this because all calls to tcsetattr() failed :-(
RTM_CHANGE if the RTM_ADD fails with an EEXIST.
Allow "delete! dst" (note the ``!'') to silently
fail if the RTM_DELETE fails with an ESRCH.
Also, make the ESRCH and EEXIST error conditions
more understandable to the casual observer.
Show the IP range (if specified) in "show ipcp".
Close unused descriptors 0 and 2 in interactive mode.
Pass (size_t *) rather than (int *) to sysctl().
strcpy(a, b); /* a and b are the same size */
with
strncpy(a, b, sizeof(a));
a[sizeof(a)-1] = '\0';
Making the code `correct at a glance'.

when command logging is switched on.
o Display ******** for the authkey for "show auth"
o Document how \P should be used, and document the other chat escapes
while I'm there.
o Make sure the full command is displayed when a compound command
fails - ie, "set novar rubbish" should say "set novar: Invalid command"
rather than "novar: Invalid command"
Problem pointed out by: Theo de Raadt <deraadt@cvs.openbsd.org> (among others)
line is > LINE_LEN (512 bytes), we scribble (*blush*).

Change sprintf(buf, "fixedstring") to strcpy(buf, "fixedstring").
Validate the peers suggested IP by attempting to make a routing table
entry.
Give up IPCP negotiation if the peer NAKs us with an unusable IP.
Always SIOCDIFADDR then SIOCAIFADDR when configuring the tun device.
Using SIOCSIFDSTADDR allows duplicate dst addresses (which we don't
want)!!!
Allow up to 200 interface names (was 50) (now that ppp can play server
properly).
Up the version number (1.5 -> 1.6).
Cosmetic:
Log unexpected CCP packets in the CCP log rather than the ERROR log.
Log unexpected Config Reqs in the appropriate LCP/IPCP/CCP log rather
than the ERROR log.
Log failed route additions and deletions with WARN, not TCPIP.
Log the option id and length for unrecognised IPCP options.
Change some .Sq to .Ar in the man page.
Delete AF_LINK routes as well as AF_INET.
Allow the word `default' as the arg to `delete' or in place of the
first two args (dest & netmask) to `add'.
Accept INTERFACE as the third arg to `add'.
You can now say `add default interface' to create a default route
through the tun interface. It's reported that subsequent bind()s
will bind to a broadcast address and not to the address currently
assigned to the tun device - this is the first step towards
supporting that first connection that was around from before the
dynamic IP negotiation....
Remove extraneous decls.
Add ``const'' to several places.
Allow ``make NOALIAS=1'' to remove IP aliasing.
Merge with OpenBSD - only the Makefiles vary.
We can now survive a compile with
-Wall -Wbad-function-cast -Wcast-align -Wcast-qual
-Winline -Wmissing-declarations -Wmissing-prototypes
-Wnested-externs -Wpointer-arith -Wredundant-decls
-Wshadow -Wstrict-prototypes -Wwrite-strings -Wchar-subscripts
(although the Makefile just contains -Wall).
o Add "allow" command:
"allow users a b c" gives access to users a, b and c.
"allow modes auto" gives those users access to auto mode only.
"allow users *" and "allow modes *" are accepted.
No users and all modes are allowed by default.
UID 0 can do anything.
o Set the current label with the "load" and "dial" commands
so that the call to ppp.linkdown makes sense.
o Up the verison number.
o Don't OR MODE_AUTO for -background and -ddial.
o Don't OR MODE_INTER when we get a diagnostic connection.
o Allow up to 40 args per line (was 20).
o "set ifaddr" only changes the interface in AUTO mode (with other
modes, it happens after IPCP negotiation).
o Sort command descriptions in the man page.
o Support -dedicated mode where we just talk ppp forever (no login etc).
Stay as the invoking uid as much as possible.
Execution as a normal user is still forbidden for now,
so these changes are pretty ineffective.
The next commit will implement the modifications suggested
on -hackers a number of days ago.
o Add missing $Id$s
o Move extern decls from .c -> .h files
o Staticize
o Remove #includes from .h files
o style(9)ify includes
o bcopy -> memcpy
bzero -> memset
bcmp -> memcmp
index -> strchr
rindex -> strrchr
o Move timeout.h -> timer.h (making it consistent w/ timer.c)
o Add -Wmissing-prototypes
file get created. We don't create lock files over non-tty
connections, but we *do* create lock files in -direct mode.
This leaves us capable of adding utmp/wtmp support for
successful pap & chap logins (coming soon).
