mpd4 on sparc64 problem (maybe netgraph involved)

[Volodymyr Kostyrko]

0k, I've finally get my hands to this stuff...

I have a host machine (i386) with many i386 clients and one sparc64 all
configured the same way. All i386 client work just fine, while sparc64
one refuses to do so.

This is a config sample:
out0:
   new -n -i ng0 SG PPPoE
   set auth authname negative1
   set bundle no multilink compression
   set bundle yes encryption
   set ecp enable des
   set iface addrs 1.1.1.1 2.2.2.2
   set iface disable on-demand proxy-arp tcpmssfix
   set iface route default
   set ipcp ranges 0.0.0.0/0 0.0.0.0/0
   set link no pap chap
   set link accept chap-md5
   set link yes acfcomp protocomp
   open

This config works just fine on i386, but fails on sparc. The problem
seems to be in echo/reply handling. On sparc64 echo/reply looks this way:

21:49:14.140583 PPPoE  [ses 0x230] LCP, Echo-Request (0x09), id 139,
length 10
         encoded length 8 (=Option(s) length 4)
           Magic-Num 0xa00fbb83
21:49:14.141577 PPPoE  [ses 0x230] LCP, Echo-Reply (0x0a), id 139, length 10
         encoded length 8 (=Option(s) length 4)
           Magic-Num 0xf09f2427

And on i386 like this:

21:49:13.441359 PPPoE  [ses 0x218] LCP, Echo-Request (0x09), id 174,
length 10
         encoded length 8 (=Option(s) length 4)
           Magic-Num 0x98036415
21:49:13.443434 PPPoE  [ses 0x218] LCP, Echo-Reply (0x0a), id 174, length 10
         encoded length 8 (=Option(s) length 4)
           Magic-Num 0x357f56e9

The i386 version is just fine, while sparc64 one results in following
logs on the host machine:

Mercy! I'm down...
