re: routed core dumps on 5.0

[matthew green <mrg%eterna.com.au@localhost>]

   I've installed 5.0 on an Ultra 5 and noticed that routed core dumps as
   soon as it is started. Starting it in foreground mode gives the
   following:
   
   ultra5b# /sbin/routed -q -d -t -v
   routed: version 2.28
   -- 21:27:59 --
   Tracing actions started
   Add interface hme0 10.0.1.164     -->10.0.1.0/24     
   RCVBUF=61440
   turn on RIP
   [1]   Bus error (core dumped) /sbin/routed -q -d -t -v
   ultra5b# 
   
   This is with the 5.0 GENERIC kernel and just the on-board ethernet
   interface. A backtrace on the core file shows it's failing in ifinit():
   
   Core was generated by `routed'.
   Program terminated with signal 10, Bus error.
   #0  0x0000000000103394 in ifinit ()
   (gdb) bt
   #0  0x0000000000103394 in ifinit ()
   #1  0x0000000000106cbc in main ()
   (gdb)
   
   I'm guessing that this is a word length or alignment issue, any
   suggestions as to what to look for?


hmm, this may be an alignment issue yes.  the code in ifinit()
casts a char * buffer to a structure.  possibly it needs to
memcpy() it into a valid structure... the loop starting with:

        for (ifam = (struct ifa_msghdr *)sysctl_buf;

appears to be the problem.  it's a big function..
