  "message": "multicast: do not restore deleted record source filter mode to new one\n\nThere are two scenarios that we will restore deleted records. The first is\nwhen device down and up(or unmap/remap). In this scenario the new filter\nmode is same with previous one. Because we get it from in_dev-\u003emc_list and\nwe do not touch it during device down and up.\n\nThe other scenario is when a new socket join a group which was just delete\nand not finish sending status reports. In this scenario, we should use the\ncurrent filter mode instead of restore old one. Here are 4 cases in total.\n\nold_socket        new_socket       before_fix       after_fix\n  IN(A)             IN(A)           ALLOW(A)         ALLOW(A)\n  IN(A)             EX( )           TO_IN( )         TO_EX( )\n  EX( )             IN(A)           TO_EX( )         ALLOW(A)\n  EX( )             EX( )           TO_EX( )         TO_EX( )\n\nFixes: 24803f38a5c0b (igmp: do not remove igmp souce list info when set link down)\nFixes: 1666d49e1d416 (mld: do not remove mld souce list info when set link down)\nSigned-off-by: Hangbin Liu \u003cliuhangbin@gmail.com\u003e\nSigned-off-by: David S.
