The panic on module ppp seems to be in pppfcs call.
The system panics while using natd (network address translator) and pppd
(line 570 of file /usr/src/sys/net/ppp_tty.c).
It arises when ppp_fcs receive a len less than zero.
static u_short
pppfcs(fcs, cp, len)
register u_short fcs;
register u_char *cp;
register int len;
{
while (len--)
fcs = PPP_FCS(fcs, *cp++);
return (fcs);
}
Can someone please guide me what to do if this function receives
len < 0 ???
In a test with a printf... it receives len = -17.
Thanks for any help.
Sergio Lenzi.
