+Subject: [PATCH] pimd: Prevent crash of pim when auto-rp's socket is not
+ initialized
+
+If the socket associated with the auto-rp fails to initialize then
+the memory for the auto-rp is just dropped on the floor.  Additionally
+any type of attempt at using the feature will just cause pimd to crash,
+when the pointer is derefed.  Since it is derefed all over the place
+without checking.
+
+Clearly if you cannot bind/use the socket let's allow continuation.
+
+Fixes: #17540
