[ECOS] IPV6 Testing

[ECOS] IPV6 Testing

[bhanuprakash kandimalla]

Hello ECOS World:
I am testing ecos for i386pc(with net template). I am
using the test case as mentioned in the ecos document.
When I called the (ping_test.c file) net_test()
function ( I commented the ipv4 part) I am always
getting the following message: "No Router
advertisement received"
Which means that cyg_net_get_ipv6_advrouter() is
returning 0. Can someone suggest me what this
net_test() will test for IPV6. My intention is to
ping6 another IPV6 host. The ping from another ipv6
host to the target is working just fine.
Thanks a bunch,
Bhanu.

By default, eCos expects an IPv6 router advertisent server, such as
radvd, on the network. This allows the IPv6 host to make its own IP
address from the network portion advertised in the rputer advert and
the MAC address for the lower part of the IP address.

Either starically configure the IPv6 addresses or start a radvd
daemon.

Statically...can this be done in the config tool? In
the config tool, I already selected
BasicNetworkingFramework-->INET support-->IPv6
Support. I disabled the option "Options controlling
IPv6 routing.
I am using all static IPv4 and Ipv6 addresses. Ping4
works fine.
For ping6, I provide the IPV6 address as following:
void ping6_start(void)
{
	struct sockaddr_in6 ipv6router;
	struct in6_addr in6addr={{{0xfe,0x80, 0, 0, 0, 0, 0,
0, 0x2, 0x1, 0x02, 0xff,0xfe, 0x37, 0x2e, 0xa0}}};
	
	
	ipv6router.sin6_len=sizeof(ipv6router);
	ipv6router.sin6_family=AF_INET6;
	ipv6router.sin6_port=0;
	ipv6router.sin6_addr=in6addr;
	
    ping6_test(&ipv6router);
}

Am i missing anything here? I am getting the following
message:
"PING6 server fe80::201:2ff:fe37:2ea0
sendto: No route to host". This message will be
repeated 16 times. 
This is failing in the get_socket().
if (!sock->conn) {
    LWIP_DEBUGF(SOCKETS_DEBUG, ("get_socket(%d): not
active\n", s));
    set_errno(EBADF);
	diag_printf("\nget_socket : sock=Null\n");
    return NULL;
  }
This is always returning NULL.
Can someone suggest what I am doing wrong here or how
to fix this. My intention is just to ping6 from my
ecos target to another ipv6 host machine connected to
the target.
Thanks in advance,
Bhanu.

So you don't have a valid route.

Add a call to show_network_tables(). That will print out all the
addresses the interfaces have and the routing table.

I am wondering how is this different from IPv4. With
the same functions for ipv4, ping(ipv4) works fine
from the target. I guess I am missing a basic concept
here. I don't have much knowledge about IPV6 stuff.
Can someone suggest me what is missing here. I
appreciate any help

For reference I am attaching a textfile for the
routing information.         

Thanks,
Bhanu.

IPv6 works just the same as IPv4 in terms of
routing. fe80::201:2ff:fe37:2ea0 is not on any of the directly
connected nets. So it has to be routed through a
gateway. Unforutately, you don't have any routes to gateways
configured and not default route. Hence it does not know where to send
the packet and so it is printing the error message. 

You need to sort out your IP addresses and routers and make sure eCos
knows this information. Probably the easiest way to do this is use
radvd or some other router advertisement program.

Re: [ECOS] IPv6 testing

[kross]

Hi Laurie,

We have an automated test system in Fitnesse/TestNG which tests all existing functionality include IPv4 features. For this product revision IPv6 is required,and we have not to date done any bench testing. We are still in resource planning. We sell thousands per year so we need to be quite careful with testing.

The product interfaces all our other rectifier products to snmp V1/V2/V3 and http/s (among other interfaces) with IPv4. The test requirement is time bound. We will do the testing here (in China really) but it will take time to set. We could create a simulated network but I am a little uneasy about real world/simulation match.

Defects are addressed through Jira at the moment.

At this point I am asking for opinions on testing IPv6 from people who have done it.

Re: [ECOS] IPv6 testing

[Laurie Gellatly]

I'm unclear on what you are regression testing. Is the regression testing for the IPv6 that already exists in a current product or for the rest of the product that now has IPv6 added? What are the business requirements of the product? How well can you define the scope. What company selection criteria do you have? How will you address any defects?

I would like to hear your opinions on regression testing IPv6 (how do you do it? how much of the feature set do you cover?). We have penty of talent to do this in house but the network is IPv4 and firewalled very heavily.

[ECOS] IPv6 testing

[kross]

We are porting 16MB of code slowly over to eCos. At this point we are shifting to lwip as of the first step. The new hardware will be eCos (from Integrity).

I am investigating regression testing of IPv6 and am wondering if and who I can outsource this to. I would like to hear your opinions on regression testing IPv6 (how do you do it? how much of the feature set do you cover?). We have penty of talent to do this in house but the network is IPv4 and firewalled very heavily.
