utils: return default family when rtm_family is not RTNL_FAMILY_IPMR/IP6MR
|
||
|
|
|
||
|
|
When we get a multicast route, the rtm_type is RTN_MULTICAST, but the
|
||
|
|
rtm_family may be AF_INET. If we only check the type with RTNL_FAMILY_IPMR,
|
||
|
|
we will get malformed address. e.g.
|
||
|
|
|
||
|
|
+ ip -4 route add multicast 172.111.1.1 dev em1 table main
|
||
|
|
|
||
|
|
Before fix:
|
||
|
|
+ ip route list type multicast table main
|
||
|
|
multicast ac6f:101:800:400:400:0:3c00:0 dev em1 scope link
|
||
|
|
|
||
|
|
After fix:
|
||
|
|
+ ip route list type multicast table main
|
||
|
|
multicast 172.111.1.1 dev em1 scope link
|
||
|
|
|
||
|
|
