[lwip-devel] [bug #21680] PPP upap_rauthnak() drops legal NAK packets

[Iordan Neshev]

Follow-up Comment #4, bug #21680 (project lwip):

I compared the the current lwip ppp implementation
with ucip (which seems to be dead) and pppd 2.4.5
(which is just 2 weeks old). 

The latest release (ucip1-0-3.zip) that can be 
downloaded from http://sourceforge.net/projects/ucip/
is much different when compared with the sources I got
via cvs. The conclusion is that there is nothing 
to port from ucip, but it was very helpful to 
look at it because I understood better what Marc did. 
Thanks, Simon.

There are some fixes in pppd 2.4.5 that I wish to
backport here. Unfortunately the function/struct/var/const
definitions in pppd appear in different order.
The order in lwip is better, but I reverted it because
the comparison is much harder.

The new files are attached. I'll be glad if someone
can test them. I may have mistaken some #if 0 or #endif.

PS: please take a look at
