Wang Hai ea2fce88d2 mld: fix memory leak in ipv6_mc_destroy_dev() ... Commit a84d016479 ("mld: fix memory leak in mld_del_delrec()") fixed the memory leak of MLD, but missing the ipv6_mc_destroy_dev() path, in which mca_sources are leaked after ma_put(). Using ip6_mc_clear_src() to take care of the missing free. BUG: memory leak unreferenced object 0xffff8881113d3180 (size 64): comm "syz-executor071", pid 389, jiffies 4294887985 (age 17.943s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 ff 02 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 00 ................ backtrace: [<000000002cbc483c>] kmalloc include/linux/slab.h:555 [inline] [<000000002cbc483c>] kzalloc include/linux/slab.h:669 [inline] [<000000002cbc483c>] ip6_mc_add1_src net/ipv6/mcast.c:2237 [inline] [<000000002cbc483c>] ip6_mc_add_src+0x7f5/0xbb0 net/ipv6/mcast.c:2357 [<0000000058b8b1ff>] ip6_mc_source+0xe0c/0x1530 net/ipv6/mcast.c:449 [<000000000bfc4fb5>] do_ipv6_setsockopt.isra.12+0x1b2c/0x3b30 net/ipv6/ipv6_sockglue.c:754 [<00000000e4e7a722>] ipv6_setsockopt+0xda/0x150 net/ipv6/ipv6_sockglue.c:950 [<0000000029260d9a>] rawv6_setsockopt+0x45/0x100 net/ipv6/raw.c:1081 [<000000005c1b46f9>] __sys_setsockopt+0x131/0x210 net/socket.c:2132 [<000000008491f7db>] __do_sys_setsockopt net/socket.c:2148 [inline] [<000000008491f7db>] __se_sys_setsockopt net/socket.c:2145 [inline] [<000000008491f7db>] __x64_sys_setsockopt+0xba/0x150 net/socket.c:2145 [<00000000c7bc11c5>] do_syscall_64+0xa1/0x530 arch/x86/entry/common.c:295 [<000000005fb7a3f3>] entry_SYSCALL_64_after_hwframe+0x49/0xb3 Fixes: 1666d49e1d ("mld: do not remove mld souce list info when set link down") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Wang Hai <wanghai38@huawei.com> Acked-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: David S.
