(I completely mis-read the rfc last time 'round!)
This means:
o Better CCP/WARN Reset diagnostics.
o After we've sent a REQ and before we've received an ACK, we drop
incoming compressed data and send another REQ.
o Before sending an ACK, re-sequence all pending PRI_NORMAL data in
the modem queue so that pending packets won't get to the peer
*after* the ResetAck.
o Send ACKs with the `identifier' from the REQ frame.
o After we've received a correct ACK, duplicate ACKs are ok (and will
reset our history).
o Incorrect ACKs (not matching the last REQ) are moaned about and dropped.
Also,
o Calculate the correct FCS after compressing a packet. DEFLATE
*may* produce an mbuf with more than a single link in the chain,
but HdlcOutput didn't know how to calculate the FCS :-(
o Make `struct fsm'::reqid a u_char, not an int.
This fix will prevent us from sending id `255' 2,000,000,000 times
before wrapping to `0' for another 2,000,000,000 sends :-/
o Bump the version number a little.
The end result: DEFLATE now works over an unreliable link layer.
I can txfr a 1.5Mb kernel over a (rather bad) null-modem
cable at an average of 21679 bytes per second using rcp.
Repeat after me: Don't test compression using a loopback ppp/tcp setup as
we never lose packets and therefore never have to reset!
With a keymap with accent key definitions loaded to syscons, you press
an accent key followed by a regular letter key to produce an accented
letter. Press an accent key followed by the space bar to get the
accent letter itself.
Code is based on the ideas and work by jmrueda@diatel.upm.es and
totii@est.is.
PR: i386/4016
- Added keywords for accent (dead) keys: dgra, dacu, dcir, dtil...
- Recognize accent map definitions.
<accent_map_definition> ::= <accent_key_name> <accent_char> <accent_map>
<accent_key_name> ::= dgra | dacu | dcir | dtil | dmac | dbre | ddot |
duml | dsla | drin | dced | dapo | ddac | dogo |
dcar
<accent_map> ::= <map_entry>
| <map_entry> <accent_map>
<map_entry> ::= ( <regular_letter_char> <accented_char> )
- Use ioctls PIO_DEADKEYMAP and GIO_DEADKEYMAP to set and get the accent
key map table in syscons.
- Made the output for the -L option more intelligible and look like
initializers in kbdtables.h.
- Reorganized print functions in order to print the accent key map.
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.
not in -auto mode isn't a good idea, and that the
add should be done in ppp.linkup instead.
Change "add 0 0 HISADDR" to "add default HISADDR". It's
more intuitive.
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.
interrupted with a SIGALRM. In fact, select() sets the
passed time to zero, making the previous implementation
terminate always after 1/10th of a second !
Also, deal with someone changing the clock while we're
sleeping (and restart the whole sleep).

When CCP is originally negotiated, the only thing we can be
sure about is that we've started adding data to the inflate
dictionary either before or at the same time as the peer. This
is ok, 'cos DEFLATE is a `sliding window' compressor.
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().
Don't read(fd, buffer, 0) and think ppp has closed the
connection when `buffer' is full, instead, flush most of
buffer to the terminal and read() for a reasonable length.
This fixes "show route" when there's more than 2k of
routing output.
Based on the report from Dave Bodenstab.
- Turn off PnP COM device enumeration procedure if the user explicitly
specifies a protocol type with the "-t" option.
- Accept "-t auto". Now the user may entirely omit the "-t" option
in the command line, or specify "-t auto" in order to make moused
detect an appropriate protocol type automatically. In the
previous version, moused did so only if the "-t" option is absent
in the command line. ("-t auto" won't disable PnP COM device
enumeration.)
- Updated the man page.
strcpy(a, b); /* a and b are the same size */

Disallow connections from port numbers <1024 as low port numbers
can only really mean trouble (ftp bounces etc.).

fd_set, make sure that all descriptors >2 are closed
when we start - otherwise we're asking for a dump in
FD_SET().
Problem pointed out by: Theo de Raadt <deraadt@cvs.openbsd.org>
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)
GCC suppresses the warning for ``standard'' header files, but since the
headers do not come from the ``standard'' place in a ``make world'', GCC
doesn't get it.
etc., so that (this part of) `LIBOWN=... make world' can be run by users
other than root. Actually, use BINOWN instead of LIBOWN, since the files
that we install in /usr/libdata are not libraries, and LIBOWN is not
used for anything else in /usr/libdata.
Rewrote all the rules and cleaned up.

Change sprintf(buf, "fixedstring") to strcpy(buf, "fixedstring").
all RTF_WASCLONED routes, and the second removes the
others. This avoids the situation where we've added an
RTF_CLONING route (such as ``default''), created some
clones, then deleted the CLONING route before the
WASCLONED route(s). Without the two passes, we get
errno (not rtm_errno) set to ESRCH when deleting the
WASCLONED route, despite the deletion succeeding !
Also:
Enhance the route operation failure diagnostics.
Make portability #ifdefs a bit more generic.
change from
ioctl(fd, PIOC<foo>, &i);
to
ioctl(fd, PIOC<foo>, i);
This is going from the _IOW to _IO ioctl macro. The kernel, procctl, and
truss must be in synch for it all to work (not doing so will get errors about
inappropriate ioctl's, fortunately). Hopefully I didn't forget anything :).
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.
Changed lots of %ld's in format strings back to %d. %ld was right
when daddr_t was long, but Lite2 changed daddr_t to int32_t which
is implemented as `int' on i386's.
