Ondřej Surý d76ab69772 Attach to the dns_dispatchmgr in the dns_view object ... The dns_dispatchmgr object was only set in the dns_view object making it prone to use-after-free in the dns_xfrin unit when shutting down named. Remove dns_view_setdispatchmgr() and optionally pass the dispatchmgr directly to dns_view_create() when it is attached and not just assigned, so the dns_dispatchmgr doesn't cease to exist too early. The dns_view_getdnsdispatchmgr() is now protected by the RCU lock, the dispatchmgr reference is incremented, so the caller needs to detach from it, and the function can return NULL in case the dns_view has been already shut down.		2023-08-15 10:25:37 -07:00
