"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix race when deleting quota root from the dirty cow roots list\n\nWhen disabling quotas we are deleting the quota root from the list\nfs_info->dirty_cowonly_roots without taking the lock that protects it,\nwhich is struct btrfs_fs_info::trans_lock. This unsynchronized list\nmanipulation may cause chaos if there's another concurrent manipulation\nof this list, such as when adding a root to it with\nctree.c:add_root_to_dirty_list().\n\nThis can result in all sorts of weird failures caused by a race, such as\nthe following crash:\n\n [337571.278245] general protection fault, probably for non-canonical address 0xdead000000000108: 0000 [#1] PREEMPT SMP PTI\n [337571.278933] CPU: 1 PID: 115447 Comm: btrfs Tainted: G W 6.4.0-rc6-btrfs-next-134+ #1\n [337571.279153] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.14.0-0-g155821a1990b-prebuilt.qemu.org 04/01/2014\n [337571.279572] RIP: 0010:commit_cowonly_roots+0x11f/0x250 [btrfs]\n [337571.279928] Code: 85 38 06 00 (...)\n [337571.280363] RSP: 0018:ffff9f63446efba0 EFLAGS: 00010206\n [337571.280582] RAX: ffff942d98ec2638 RBX: ffff9430b82b4c30 RCX: 0000000449e1c000\n [337571.280798] RDX: dead000000000100 RSI: ffff9430021e4900 RDI: 0000000000036070\n [337571.281015] RBP: ffff942d98ec2000 R08: ffff942d98ec2000 R09: 000000000000015b\n [337571.281254] R10: 0000000000000009 R11: 0000000000000001 R12: ffff942fe8fbf600\n [337571.281476] R13: ffff942dabe23040 R14: ffff942dabe20800 R15: ffff942d92cf3b48\n [337571.281723] FS: 00007f478adb7340(0000) GS:ffff94349fa40000(0000) knlGS:0000000000000000\n [337571.281950] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n [337571.282184] CR2: 00007f478ab9a3d5 CR3: 000000001e02c001 CR4: 0000000000370ee0\n [337571.282416] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n [337571.282647] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n [337571.282874] Call Trace:\n [337571.283101] <TASK>\n [337571.283327] ? __die_body+0x1b/0x60\n [337571.283570] ? die_addr+0x39/0x60\n [337571.283796] ? exc_general_protection+0x22e/0x430\n [337571.284022] ? asm_exc_general_protection+0x22/0x30\n [337571.284251] ? commit_cowonly_roots+0x11f/0x250 [btrfs]\n [337571.284531] btrfs_commit_transaction+0x42e/0xf90 [btrfs]\n [337571.284803] ? _raw_spin_unlock+0x15/0x30\n [337571.285031] ? release_extent_buffer+0x103/0x130 [btrfs]\n [337571.285305] reset_balance_state+0x152/0x1b0 [btrfs]\n [337571.285578] btrfs_balance+0xa50/0x11e0 [btrfs]\n [337571.285864] ? __kmem_cache_alloc_node+0x14a/0x410\n [337571.286086] btrfs_ioctl+0x249a/0x3320 [btrfs]\n [337571.286358] ? mod_objcg_state+0xd2/0x360\n [337571.286577] ? refill_obj_stock+0xb0/0x160\n [337571.286798] ? seq_release+0x25/0x30\n [337571.287016] ? __rseq_handle_notify_resume+0x3ba/0x4b0\n [337571.287235] ? percpu_counter_add_batch+0x2e/0xa0\n [337571.287455] ? __x64_sys_ioctl+0x88/0xc0\n [337571.287675] __x64_sys_ioctl+0x88/0xc0\n [337571.287901] do_syscall_64+0x38/0x90\n [337571.288126] entry_SYSCALL_64_after_hwframe+0x72/0xdc\n [337571.288352] RIP: 0033:0x7f478aaffe9b\n\nSo fix this by locking struct btrfs_fs_info::trans_lock before deleting\nthe quota root from that list."
