Hi,
I was trying to figure out how the rp_filter does the
source address validation.
I traced out the location in source code(2.4.18) to
fib_validate_source() in net/ipv4/fib_frontend.c
But here the line where I think the rp filter comes in
rpf = IN_DEV_RPFILTER(in_dev);
But this looks for the enabling of rp_filter for the all the interfaces and
for the individual interfaces.
Then comes the line
if (rpf)
goto e_inval;
That means if rp filtering is enabled return EINVAL!!!!!!
I seem to be missing a lot of things
Could some one help me out on this
Regards
KK
