      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: fix memory leak in ocfs2_mount_volume()\n\nThere is a memory leak reported by kmemleak:\n\n  unreferenced object 0xffff88810cc65e60 (size 32):\n    comm \"mount.ocfs2\", pid 23753, jiffies 4302528942 (age 34735.105s)\n    hex dump (first 32 bytes):\n      10 00 00 00 00 00 00 00 00 01 01 01 01 01 01 01  ................\n      01 01 01 01 01 01 01 01 00 00 00 00 00 00 00 00  ................\n    backtrace:\n      [<ffffffff8170f73d>] __kmalloc+0x4d/0x150\n      [<ffffffffa0ac3f51>] ocfs2_compute_replay_slots+0x121/0x330 [ocfs2]\n      [<ffffffffa0b65165>] ocfs2_check_volume+0x485/0x900 [ocfs2]\n      [<ffffffffa0b68129>] ocfs2_mount_volume.isra.0+0x1e9/0x650 [ocfs2]\n      [<ffffffffa0b7160b>] ocfs2_fill_super+0xe0b/0x1740 [ocfs2]\n      [<ffffffff818e1fe2>] mount_bdev+0x312/0x400\n      [<ffffffff819a086d>] legacy_get_tree+0xed/0x1d0\n      [<ffffffff818de82d>] vfs_get_tree+0x7d/0x230\n      [<ffffffff81957f92>] path_mount+0xd62/0x1760\n      [<ffffffff81958a5a>] do_mount+0xca/0xe0\n      [<ffffffff81958d3c>] __x64_sys_mount+0x12c/0x1a0\n      [<ffffffff82f26f15>] do_syscall_64+0x35/0x80\n      [<ffffffff8300006a>] entry_SYSCALL_64_after_hwframe+0x46/0xb0\n\nThis call stack is related to two problems.  Firstly, the ocfs2 super uses\n\"replay_map\" to trace online/offline slots, in order to recover offline\nslots during recovery and mount.  But when ocfs2_truncate_log_init()\nreturns an error in ocfs2_mount_volume(), the memory of \"replay_map\" will\nnot be freed in error handling path.  Secondly, the memory of \"replay_map\"\nwill not be freed if d_make_root() returns an error in ocfs2_fill_super().\nBut the memory of \"replay_map\" will be freed normally when completing\nrecovery and mount in ocfs2_complete_mount_recovery().\n\nFix the first problem by adding error handling path to free \"replay_map\"\nwhen ocfs2_truncate_log_init() fails.  And fix the second problem by\ncalling ocfs2_free_replay_slots(osb) in the error handling path\n\"out_dismount\".  In addition, since ocfs2_free_replay_slots() is static,\nit is necessary to remove its static attribute and declare it in header\nfile.",
