Changes by: pavlin@xorpc.icir.org. 03/09/12 15:39:09
Modified files:
xorp/fea/: ifconfig_get_proc_linux.cc
Log message:
* Refactor the /proc information fetch mechanism (mostly the IPv4
case):
- First we call the ioctl()'s pull_config() to get most
of the interface information (including the IP aliases information).
- Then, in case of IPv4 we get the list of interfaces from
/proc/net/dev . This info would include the tunnel interface names
that is not returned by the ioctl(SIOCGIFCONF) method.
Then, for every interface name that is not on the interface tree
(i.e., that ioctl(SIOCGIFCONF) doesn't know about)
we call IfConfigIoctl::parse_buffer_ifreq() that will call
various ioctl()'s to fill-in the missing info for that interface
(MTU, IP address, etc).
This is the model used by Linux's ifconfig (from net-tools), and
seems to be the only workaround of collecting all the missing
interface information.
* Few tweaks to the IPv6 case, where we need to use /proc/net/if_inet6
to get the IP addresses, etc (similar to Linux's ifconfig).
We still don't obtain the endpoint address in case of IPv6 point-to-point
interfaces, because there is no information in ifconfig's source code
or the Linux kernel code how to do that. Could be that
RedHat-7.x (Linux kernel 2.4.x) doesn't support IPv6 tunnels?
