"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: zoned: fix lock ordering in btrfs_zone_activate()\n\nThe btrfs CI reported a lockdep warning as follows by running generic\ngeneric/129.\n\n WARNING: possible circular locking dependency detected\n 6.7.0-rc5+ #1 Not tainted\n ------------------------------------------------------\n kworker/u5:5/793427 is trying to acquire lock:\n ffff88813256d028 (&cache->lock){+.+.}-{2:2}, at: btrfs_zone_finish_one_bg+0x5e/0x130\n but task is already holding lock:\n ffff88810a23a318 (&fs_info->zone_active_bgs_lock){+.+.}-{2:2}, at: btrfs_zone_finish_one_bg+0x34/0x130\n which lock already depends on the new lock.\n\n the existing dependency chain (in reverse order) is:\n -> #1 (&fs_info->zone_active_bgs_lock){+.+.}-{2:2}:\n ...\n -> #0 (&cache->lock){+.+.}-{2:2}:\n ...\n\nThis is because we take fs_info->zone_active_bgs_lock after a block_group's\nlock in btrfs_zone_activate() while doing the opposite in other places.\n\nFix the issue by expanding the fs_info->zone_active_bgs_lock's critical\nsection and taking it before a block_group's lock."
