David L Stevens 5ab4a6c81e [IPV6] mcast: Fix multiple issues in MLDv2 reports. ... The below "jumbo" patch fixes the following problems in MLDv2. 1) Add necessary "ntohs" to recent "pskb_may_pull" check [breaks all nonzero source queries on little-endian (!)] 2) Add locking to source filter list [resend of prior patch] 3) fix "mld_marksources()" to a) send nothing when all queried sources are excluded b) send full exclude report when source queried sources are not excluded c) don't schedule a timer when there's nothing to report NOTE: RFC 3810 specifies the source list should be saved and each source reported individually as an IS_IN. This is an obvious DOS path, requiring the host to store and then multicast as many sources as are queried (e.g., millions...). This alternative sends a full, relevant report that's limited to number of sources present on the machine. 4) fix "add_grec()" to send empty-source records when it should The original check doesn't account for a non-empty source list with all sources inactive; the new code keeps that short-circuit case, and also generates the group header with an empty list if needed. 5) fix mca_crcount decrement to be after add_grec(), which needs its original value These issues (other than item #1 ;-) ) were all found by Yan Zheng, much thanks!
