* Correct the way the uucp lock file and the ttyXX.if lockBrian Somers1997-09-221-22/+13
| | | | | | | | | | 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). Notes: svn path=/head/; revision=29696
* It turns out that the following:Brian Somers1997-09-211-2/+1
| | | | | | | | | | | | | | | close(1); close(2); x = open(ctermid(NULL), O_RDWR|O_NONBLOCK); close(0) on a tty causes select() to return an exception for descriptor x ! This is the case in RELENG_2_2, but not in 2.2.2. I'm not sure why. Instead of doing the x=open() and close(0), we just do x=0 now. Problem pointed out by: Greg Lehey <grog@lemis.com> Tomi Vainio <tomppa@fidata.fi> Notes: svn path=/head/; revision=29668

* Add "set loopback on|off", defaulting to "on".Brian Somers1997-08-211-1/+23
| | | | | | | | | | | | This tells ppp to loopback packets addressed to the ppp interface IP coming *from* the tun device. This means that you can ping the tun interface IP from inside :-) Notes: svn path=/head/; revision=28536
* Make HUP cause an exit (as it used to), and makeBrian Somers1997-07-011-5/+5
| | | | | | | | | | | | | INT cause a hangup - not exiting for -ddial & -auto. HUP must exit because init sends this at system shutdown time (why, I don't know), and we don't want to end up redialing after the HUP (due to another dfilter packet).

* Overhaul ppp:Brian Somers1997-06-091-140/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Requested by: Harlan Stenn <Harlan.Stenn@pfcs.com>Brian Somers1997-03-131-3/+3
| | | | | | | | | | | | | | Accept SIGHUP as a "re-open logfile" signal. As ppp doesn't set it's serial line to it's controlling terminal, we can use HUP :) This is a candidate for 2.2. The log.[ch] changes won't conflict, but the main.c changes will. We just want to change the kill(...,SIGHUP) to a SIGTERM and change the signal(SIGHUP,Hangup) to a pending_signal(SIGHUP,LogReOpen).

| | | | | | | | | | | These changes should fix the signal "problems" in ppp. The signal changes should really be put into 2.2 too ! The following patches should do it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dangerous! Signal handlers themself must be fixed to not call malloc, but no pended handlers, it will be correct fix. In finite case each signal handler can set some variable which will be analized later, but calling handler functions manually is too dangerous (f.e. signals not blocked while the handler or handlers switch executed in this case). Of course this code can be fixed instead of removing, but it not worth fixing in any case. Should go into 2.2 In addition sig.c code shows following dangerous fragments (there can be more, but I stop after two): This fragment if (fn == SIG_DFL || fn == SIG_IGN) { handler[sig-1] = (sig_type)0; <------------- here signal(sig,fn); } else { cause NULL pointer reference when signal comes "here", but more worse fragment is below: void handle_signals() { int sig; if (caused) for (sig=0; sig<__MAXSIG; sig++, caused>>=1) if (caused&1) (*handler[sig])(sig+1); } caused is bitmask which set corresponding bit on each signal coming. And now imagine, what happens when some signal comes (bit sets) while loop is executed (see caused>>=1 !!!) In this light carrier drop situation was (as gdb shows) 1. SIGSEGV in handle_signals because some junk called as *handler reference. 2. Since SIGSEGV was pended too (== never happens), it can cause various range of disasters.
