From: Lorenzo Colitti Date: Wed, 7 Sep 2016 04:38:35 +0000 (+0900) Subject: net: diag: make udp_diag_destroy work for mapped addresses. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f95bf346226b9b79352e05508beececc807cc37a;p=linux-beck.git net: diag: make udp_diag_destroy work for mapped addresses. udp_diag_destroy does look up the IPv4 UDP hashtable for mapped addresses, but it gets the IPv4 address to look up from the beginning of the IPv6 address instead of the end.
