+ | panic on multicast socket close after interface removal |
+ &status.wip; |
+ &a.rwatson; |
+ Due to the addition of multicast locking, a long-present memory
+ corruption bug now generates an immediate panic if an interface is
+ removed while a multicast group is in use on the interface. This
+ can manifest if running routed and using vlans. A regression test
+ has now been committed as msocket_ifnet_remove. A short-term fix
+ will be to GC references to the interface in the IPv4/IPv6
+ multicast socket options hung off of the inpcb; a long term solution
+ will require determining the correct application semantics for
+ interface removal as relates to multicast sockets. This problem is
+ described in detail in PR kern/77665. |
