Subject[Bug 1030] New: racoon causes oops when implementing IPSec key
http://bugme.osdl.org/show_bug.cgi?id=1030

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


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
eax: 00000018 ebx: f6fe8a00 ecx: 00000006 edx: 00000000
esi: 00000000 edi: 00000000 ebp: c0562520 esp: f6fb5ccc
ds: 007b es: 007b ss:0068
Process racoon (pid: 418, threadinfo=f6fb4000 task=f6fbb300)
Stack:

Code: f3 a5 a8 02 74 02 66 a5 a8 01 74 01 a4 89 d0 8b 74 24 02 8b
<0>Kernel panic: Fatal exception in interrupt
In interrupt handler = not syncing


For some of the other numbers that didn't get copied, check 67.9.9.32/oops.jpg. Email me if its
dead, which it will be after 20 august.

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.
