Subject: [IPSEC]: Fix ip_local_out when NETFILTER is off
Hi Dave:
[IPSEC]: Fix ip_local_out when NETFILTER is off
Thanks for testing with NETFILTER off because I obviously didn't :)
The code for ip_local_out/ip6_local_out is completely broken in
that case.
This patch fixes and also makes the IPsec path use the correct
local_out function so that the loop executes properly and we
don't end up nesting too deep and overrun the stack.
Signed-off-by: Herbert Xu <herbert@...dor.apana.org.au>
Cheers,
