While trying to use the sppp, I came across this situation and I think it's
a bug:
When you trying to establish connection from one peer (local) to another
(remote), you sent a CONF_REQ message to the remote peer. The remote peer
should answer with a CONF_ACK message. In the code of the sppp driver
(net/if_spppsubr.c, lines 1321 - 1357) you can see that the remote peer
send's a CONF_ACK message to the local peer
(in the line: rv = (cp->RCR)(sp, h, len);) but doesn't change it state to
STATE_ACK_SENT (as I think it should do) . Further more, you can see that
after a few lines, there are these strange lines:
case STATE_ACK_SENT:
case STATE_REQ_SENT:
sppp_cp_change_state(cp, sp, rv?
STATE_ACK_SENT: STATE_REQ_SENT);
break;
Question: if you are in the STATE_ACK_SENT why change the state to the same
one according to the value of rv?
As I understand, the state should be changed according to the value of rv,
but it should be done right after the call to cp->RCR. The it is implemented
now, the state won't be changed.
(I have a lot of problems with this driver and any help will be
appreciative)
Thank you,
