           Summary: racoon causes oops when implementing IPSec key
    Kernel Version: 2.6.0-test1
            Status: NEW
          Severity: normal
             Owner: acme@conectiva.com.br

Distribution: SuSE and LFS
Hardware Environment: e100 cards
Software Environment: ipsec-tools 0.2.2 
Problem Description: 

I setkey with a policy to use esp and ah on each box. I start racoon on each box. I punch up a web 
page on one from the other. Insta-oops x 2. 
 
Unable to handle kernel NULL pointer dereference at virtual address 00000000
 printing eip:
c02bbd06
*pde = 00000000
Oops: 0000 [#1]
CPU:    0
EIP:    0060:[<c02bbd06>]     Not tainted
EFLAGS: 00010206
EIP is at memcpy+0x1e/0x39

Steps to reproduce:

> From each box:

# !setkey -f
flush;
spdflush;
spdadd $this_box $other_box any -P out  ipsec esp/transport//use ah/transport//use;
spdadd $other_box $this_box any -P in ipsec esp/transport//use ah/transport//use;

Set up racoon (the default config would probably work, here is the gist of mine)

remote anonymous
{
        exchange_mode main;

        my_identifier address;
        peers_identifier address;

        lifetime time 1 min;    # sec,min,hour

        proposal {
                encryption_algorithm 3des;
                hash_algorithm sha1;
                authentication_method pre_shared_key ;
                dh_group 2;
        }
}

sainfo anonymous
{
        lifetime time 20 min;
        encryption_algorithm 3des ;
        authentication_algorithm hmac_sha1;
        compression_algorithm deflate ;
}

Start racoon on each box. 

Open a new connection to cause a key exchange.

Hit the reset button on each box.
