The command "ip mroute show" is not showing routes when "to" and/or "from"
filter is applied.
root@mazhar:~# ip mroute show
(10.202.30.101, 235.1.2.3) Iif: eth0 Oifs: eth1
But When I applied filter, it does not show anything.
root@mazhar:~# ip mroute show 235.1.2.3 from 10.202.30.101
root@mazhar:~#

This flag is only for the netlink protocol (multi-part messages), no reason
to reject messages without it.
Note that this flag was removed by the following kernel patches (v3.14)

For some address families (like AF_PACKET) it is helpful to have the
length when prenting the address.

mroute was using /proc/net/ip_mr_[vif|cache] to display mroute entries. Hence,
only RT_TABLE_DEFAULT was displayed and only IPv4.
With rtnetlink, it is possible to display all tables for IPv4 and IPv6. The output
format is kept. Also, like before the patch, statistics are displayed when user specify
the '-s' argument.
The patch also adds the support of 'ip monitor mroute', which is now possible.

The command "ip mroute show" will only show the first Oif.
mark@flappie:~$ ip mroute show
(192.168.1.1, 224.0.0.123) Iif: _rename Oifs: eth1
mark@flappie:~$ cat /proc/net/ip_mr_cache
Group Origin Iif Pkts Bytes Wrong Oifs
7B0000E0 0101A8C0 2 0 0 0 0:1 1:1
This shows 2 Oifs here. However, ipmroute.c, function read_mroute_list(), uses sscanf() with a %s mask for oiflist, which stops after the first whitespace (i.e. after Oif 0:1). The patch below fixes this to read until the newline (though I'm not sure whether this is the proper way to fix it).
After this patch:
mark@flappie:~/iproute-20090324/ip$ ./ip mroute show
(192.168.1.1, 224.0.0.123) Iif: _rename Oifs: eth1 eth0
