Subject: [PATCH 06/32] CGTS-3744: route: do not cache fib route info on local
|
|
routes with oif
|
|
|
|
For local routes that require a particular output interface we do not want to
|
|
cache the result. Caching the result causes incorrect behaviour when there are
|
|
multiple source addresses on the interface. The end result being that if the
|
|
intended recipient is waiting on that interface for the packet he won't receive
|
|
it because it will be delivered on the loopback interface and the IP_PKTINFO
|
|
ipi_ifindex will be set to the loopback interface as well.
|
|
|
|
This can be tested by running a program such as "dhcp_release" which attempts
|
|
to inject a packet on a particular interface so that it is received by another
|
|
program on the same board. The receiving process should see an IP_PKTINFO
|
|
ipi_ifndex value of the source interface (e.g., eth1) instead of the loopback
|
|
interface (e.g., lo). The packet will still appear on the loopback interface
|
|
in tcpdump but the important aspect is that the CMSG info is correct.
|
|
|
|
Sample dhcp_release command line:
|
|
|
|
dhcp_release eth1 192.168.204.222 02:11:33:22:44:66
