It was not a good idea to remove csu_header from struct cspace, it had
ramifications which I didn't notice.
Restore src/usr.sbin/ppp/slcompress.h to the way it was, since MAX_HDR
was already defined as 128 there and it's a user program anyway.
In sys/net/slcompress.h make MAX_HDR 128 intead of MLEN to avoid
bloat.
My apologies for any inconvenience.
tree. This considerably reduces unnecessary bloat in struct slcompress.
I'm running with this change right now and have seen no negative
side-effects.
On my sytem this reduced kernel BSS by about 25KB.

sl_uncompress_tcp() and drop packets with
slot numbers that are out of range.
o Drop packets that want to use a slot that still
has an IP header length of 0 (ie, the requested
slot number is bogus again).
Without this code, if the other side mis-behaves (and
sends us garbage slot numbers), we happily ``adjust''
a memset(..., '\0', ...) TCP/IP header and promptly
cr*p all over the stack before returning.... quickly
followed by a SIGBUS.

There's still a link lockup after this happens, but my
bets are on the other side (who has already started sending
rubbish) being to blame.
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 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
Support VJ slot id compression.
Previously, ppp would negotiate a max slot between 2 & 15
(if asked), and would agree to slot id compression (if asked).
It would then proceed to use 16 slots and no compression
anyway. The result was a rather unusable connection.
o Use syslog
o Remove references to stdout/stderr (incl perror())
o Introduce VarTerm - the interactive terminal or zero
o Allow "set timeout" to affect current session
o Change "set debug" to "set log"
o Allow "set log [+|-]flag"
o Make MSEXT and PASSWDAUTH stuff the default
o Move all #ifdef DEBUG stuff into the code - this
shouldn't be too much overhead. It's now controlled
with "set log +debug"
o Add "set log command, debug, tun, warn, error, alert"
o Remove cdefs.h, and assume an ansi compiler.
o Improve all diagnostic output
o Don't trap SIGSEGV
o SIGHUP now terminates again (log files are controlled
by syslog)
o Call CloseModem() when changing devices
o Fix parsing of third arg of "delete"
I think this fixes the "magic is same" problems that some
people have been experiencing.
The man page is being rewritten. It'll follow soon.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
o Supporting SYNC SIO device (But need a device driver)
- add "set speed sync"
o Fixing bug for Predictor-1 function.
o Add new parameter that re-sent interval for set timeout commands.
o Improving RTT (Round Trip Time) and reducing processor time.
- Previous Timer service was using polling, and now using
SIGALRM ;-)
- A 0.94beta2 will not work correctly....
-- Follows are additinal feature not including 0.94beta2
o Support Proxy ARP
- add "enable/disable proxy" commands
o Marging common routine in CHAP/PAP.
o Enhancing LCP/IPCP log information.
o Support local Authfication connection on port 300x and tty.
- You can set up pair of your "hostname -s" and
password in ppp.secret. if either ppp.secret file nor
your hostname line don't exist, It will notify a message
and working as same as previous version.(Backword compatibility)
- If you did set up them, It's allow connection but nothing to do
except help and passwd command.
- add "passwd yourpasswd" commands
o Support afilter - keep Alive filter that a packet can send/receiving
according to ifilter/ofilter but doesn't count it as preventing idle
timer expires.
- Same syntax of other filters.
o Fixing bugs reported by current user for previous one. Thanks !!
