This is catastrophic for data integrity when iter-\u003epos is not\naligned to a page, because daddr/saddr do not point to the same byte in\nthe file as iter-\u003epos.  Hence we corrupt user data by copying it to the\nwrong place.\n\nIf iter-\u003epos + iomap_length() in the _iter function not aligned to a\npage, then we fail to copy a full block, and only partially populate the\ndestination block.  This is catastrophic for data confidentiality\nbecause we expose stale pmem contents.\n\nFix both of these issues by aligning copy_pos/copy_len to a page\nboundary (remember, this is fsdax so 1 fsblock == 1 base page) so that\nwe always copy full blocks.\n\nWe\u0027re not done yet -- there\u0027s no call to invalidate_inode_pages2_range,\nso programs that have the file range mmap\u0027d will continue accessing the\nold memory mapping after the file metadata updates have completed.\n\nBe careful with the return value -- if the unshare succeeds, we still\nneed to return the number of bytes that the iomap iter thinks we\u0027re\noperating on.",

For example, an unknown capability (i.e., capability with ID\ngreater than PCI_EXT_CAP_ID_MAX) or a capability that is intentionally\nchosen to be hidden from the user.\n\nHiding a capability is done by virtualizing and modifying the \u0027Next\nCapability Offset\u0027 field of the previous capability so it points to the\ncapability after the one that should be hidden.\n\nThe special case where the first capability in the list should be hidden\nis handled differently because there is no previous capability that can\nbe modified. In this case, the capability ID and version are zeroed\nwhile leaving the next pointer intact. This hides the capability and\nleaves an anchor for the rest of the capability list.\n\nHowever, today, hiding the first capability in the list is not done\nproperly if the capability is unknown, as struct\nvfio_pci_core_device-\u003epci_config_map is set to the capability ID during\ninitialization but the capability ID is not properly checked later when\nused in vfio_config_do_rw(). This leads to the following warning [1] and\nto an out-of-bounds access to ecap_perms array.\n\nFix it by checking cap_id in vfio_config_do_rw(), and if it is greater\nthan PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for direct\nread only access instead of the ecap_perms array.\n\nNote that this is safe since the above is the only case where cap_id can\nexceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, which\nare already checked before).\n\n[1]\n\nWARNING: CPU: 118 PID: 5329 at drivers/vfio/pci/vfio_pci_config.c:1900 vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]\nCPU: 118 UID: 0 PID: 5329 Comm: simx-qemu-syste Not tainted 6.12.0+ #1\n(snip)\nCall Trace:\n \u003cTASK\u003e\n ? show_regs+0x69/0x80\n ? __warn+0x8d/0x140\n ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]\n ? report_bug+0x18f/0x1a0\n ? handle_bug+0x63/0xa0\n ? exc_invalid_op+0x19/0x70\n ? asm_exc_invalid_op+0x1b/0x20\n ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]\n ? vfio_pci_config_rw+0x244/0x430 [vfio_pci_core]\n vfio_pci_rw+0x101/0x1b0 [vfio_pci_core]\n vfio_pci_core_read+0x1d/0x30 [vfio_pci_core]\n vfio_device_fops_read+0x27/0x40 [vfio]\n vfs_read+0xbd/0x340\n ? vfio_device_fops_unl_ioctl+0xbb/0x740 [vfio]\n ? __rseq_handle_notify_resume+0xa4/0x4b0\n __x64_sys_pread64+0x96/0xc0\n x64_sys_call+0x1c3d/0x20d0\n do_syscall_64+0x4d/0x120\n entry_SYSCALL_64_after_hwframe+0x76/0x7e",

Since it does not use the\nunused_bg_lock, it is possible for the following race to occur:\n\nbtrfs_create_pending_block_groups            btrfs_mark_bg_unused\n                                           if list_empty // false\n        list_del_init\n        clear_bit\n                                           else if (test_bit) // true\n                                                list_move_tail\n\nAnd we get into the exact same broken ref count and invalid new_bgs\nstate for transaction cleanup that BLOCK_GROUP_FLAG_NEW was designed to\nprevent.\n\nThe broken refcount aspect will result in a warning like:\n\n  [1272.943527] refcount_t: underflow; use-after-free.\n  [1272.943967] WARNING: CPU: 1 PID: 61 at lib/refcount.c:28 refcount_warn_saturate+0xba/0x110\n  [1272.944731] Modules linked in: btrfs virtio_net xor zstd_compress raid6_pq null_blk [last unloaded: btrfs]\n  [1272.945550] CPU: 1 UID: 0 PID: 61 Comm: kworker/u32:1 Kdump: loaded Tainted: G        W          6.14.0-rc5+ #108\n  [1272.946368] Tainted: [W]=WARN\n  [1272.946585] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.16.3-1-1 04/01/2014\n  [1272.947273] Workqueue: btrfs_discard btrfs_discard_workfn [btrfs]\n  [1272.947788] RIP: 0010:refcount_warn_saturate+0xba/0x110\n  [1272.949532] RSP: 0018:ffffbf1200247df0 EFLAGS: 00010282\n  [1272.949901] RAX: 0000000000000000 RBX: ffffa14b00e3f800 RCX: 0000000000000000\n  [1272.950437] RDX: 0000000000000000 RSI: ffffbf1200247c78 RDI: 00000000ffffdfff\n  [1272.950986] RBP: ffffa14b00dc2860 R08: 00000000ffffdfff R09: ffffffff90526268\n  [1272.951512] R10: ffffffff904762c0 R11: 0000000063666572 R12: ffffa14b00dc28c0\n  [1272.952024] R13: 0000000000000000 R14: ffffa14b00dc2868 R15: 000001285dcd12c0\n  [1272.952850] FS:  0000000000000000(0000) GS:ffffa14d33c40000(0000) knlGS:0000000000000000\n  [1272.953458] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n  [1272.953931] CR2: 00007f838cbda000 CR3: 000000010104e000 CR4: 00000000000006f0\n  [1272.954474] Call Trace:\n  [1272.954655]  \u003cTASK\u003e\n  [1272.954812]  ? refcount_warn_saturate+0xba/0x110\n  [1272.955173]  ? __warn.cold+0x93/0xd7\n  [1272.955487]  ? refcount_warn_saturate+0xba/0x110\n  [1272.955816]  ? report_bug+0xe7/0x120\n  [1272.956103]  ? handle_bug+0x53/0x90\n  [1272.956424]  ? exc_invalid_op+0x13/0x60\n  [1272.956700]  ? asm_exc_invalid_op+0x16/0x20\n  [1272.957011]  ? refcount_warn_saturate+0xba/0x110\n  [1272.957399]  btrfs_discard_cancel_work.cold+0x26/0x2b [btrfs]\n  [1272.957853]  btrfs_put_block_group.cold+0x5d/0x8e [btrfs]\n  [1272.958289]  btrfs_discard_workfn+0x194/0x380 [btrfs]\n  [1272.958729]  process_one_work+0x130/0x290\n  [1272.959026]  worker_thread+0x2ea/0x420\n  [1272.959335]  ? __pfx_worker_thread+0x10/0x10\n  [1272.959644]  kthread+0xd7/0x1c0\n  [1272.959872]  ? __pfx_kthread+0x10/0x10\n  [1272.960172]  ret_from_fork+0x30/0x50\n  [1272.960474]  ? __pfx_kthread+0x10/0x10\n  [1272.960745]  ret_from_fork_asm+0x1a/0x30\n  [1272.961035]  \u003c/TASK\u003e\n  [1272.961238] ---[ end trace 0000000000000000 ]---\n\nThough we have seen them in the async discard workfn as well.

For example, an unknown capability (i.e., capability with ID\ngreater than PCI_EXT_CAP_ID_MAX) or a capability that is intentionally\nchosen to be hidden from the user.\n\nHiding a capability is done by virtualizing and modifying the \u0027Next\nCapability Offset\u0027 field of the previous capability so it points to the\ncapability after the one that should be hidden.\n\nThe special case where the first capability in the list should be hidden\nis handled differently because there is no previous capability that can\nbe modified. In this case, the capability ID and version are zeroed\nwhile leaving the next pointer intact. This hides the capability and\nleaves an anchor for the rest of the capability list.\n\nHowever, today, hiding the first capability in the list is not done\nproperly if the capability is unknown, as struct\nvfio_pci_core_device-\u003epci_config_map is set to the capability ID during\ninitialization but the capability ID is not properly checked later when\nused in vfio_config_do_rw(). This leads to the following warning [1] and\nto an out-of-bounds access to ecap_perms array.\n\nFix it by checking cap_id in vfio_config_do_rw(), and if it is greater\nthan PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for direct\nread only access instead of the ecap_perms array.\n\nNote that this is safe since the above is the only case where cap_id can\nexceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, which\nare already checked before).\n\n[1]\n\nWARNING: CPU: 118 PID: 5329 at drivers/vfio/pci/vfio_pci_config.c:1900 vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]\nCPU: 118 UID: 0 PID: 5329 Comm: simx-qemu-syste Not tainted 6.12.0+ #1\n(snip)\nCall Trace:\n \u003cTASK\u003e\n ? show_regs+0x69/0x80\n ? __warn+0x8d/0x140\n ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]\n ? report_bug+0x18f/0x1a0\n ? handle_bug+0x63/0xa0\n ? exc_invalid_op+0x19/0x70\n ? asm_exc_invalid_op+0x1b/0x20\n ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]\n ? vfio_pci_config_rw+0x244/0x430 [vfio_pci_core]\n vfio_pci_rw+0x101/0x1b0 [vfio_pci_core]\n vfio_pci_core_read+0x1d/0x30 [vfio_pci_core]\n vfio_device_fops_read+0x27/0x40 [vfio]\n vfs_read+0xbd/0x340\n ? vfio_device_fops_unl_ioctl+0xbb/0x740 [vfio]\n ? __rseq_handle_notify_resume+0xa4/0x4b0\n __x64_sys_pread64+0x96/0xc0\n x64_sys_call+0x1c3d/0x20d0\n do_syscall_64+0x4d/0x120\n entry_SYSCALL_64_after_hwframe+0x76/0x7e",

Since it does not use the\nunused_bg_lock, it is possible for the following race to occur:\n\nbtrfs_create_pending_block_groups            btrfs_mark_bg_unused\n                                           if list_empty // false\n        list_del_init\n        clear_bit\n                                           else if (test_bit) // true\n                                                list_move_tail\n\nAnd we get into the exact same broken ref count and invalid new_bgs\nstate for transaction cleanup that BLOCK_GROUP_FLAG_NEW was designed to\nprevent.\n\nThe broken refcount aspect will result in a warning like:\n\n  [1272.943527] refcount_t: underflow; use-after-free.\n  [1272.943967] WARNING: CPU: 1 PID: 61 at lib/refcount.c:28 refcount_warn_saturate+0xba/0x110\n  [1272.944731] Modules linked in: btrfs virtio_net xor zstd_compress raid6_pq null_blk [last unloaded: btrfs]\n  [1272.945550] CPU: 1 UID: 0 PID: 61 Comm: kworker/u32:1 Kdump: loaded Tainted: G        W          6.14.0-rc5+ #108\n  [1272.946368] Tainted: [W]=WARN\n  [1272.946585] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.16.3-1-1 04/01/2014\n  [1272.947273] Workqueue: btrfs_discard btrfs_discard_workfn [btrfs]\n  [1272.947788] RIP: 0010:refcount_warn_saturate+0xba/0x110\n  [1272.949532] RSP: 0018:ffffbf1200247df0 EFLAGS: 00010282\n  [1272.949901] RAX: 0000000000000000 RBX: ffffa14b00e3f800 RCX: 0000000000000000\n  [1272.950437] RDX: 0000000000000000 RSI: ffffbf1200247c78 RDI: 00000000ffffdfff\n  [1272.950986] RBP: ffffa14b00dc2860 R08: 00000000ffffdfff R09: ffffffff90526268\n  [1272.951512] R10: ffffffff904762c0 R11: 0000000063666572 R12: ffffa14b00dc28c0\n  [1272.952024] R13: 0000000000000000 R14: ffffa14b00dc2868 R15: 000001285dcd12c0\n  [1272.952850] FS:  0000000000000000(0000) GS:ffffa14d33c40000(0000) knlGS:0000000000000000\n  [1272.953458] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n  [1272.953931] CR2: 00007f838cbda000 CR3: 000000010104e000 CR4: 00000000000006f0\n  [1272.954474] Call Trace:\n  [1272.954655]  \u003cTASK\u003e\n  [1272.954812]  ? refcount_warn_saturate+0xba/0x110\n  [1272.955173]  ? __warn.cold+0x93/0xd7\n  [1272.955487]  ? refcount_warn_saturate+0xba/0x110\n  [1272.955816]  ? report_bug+0xe7/0x120\n  [1272.956103]  ? handle_bug+0x53/0x90\n  [1272.956424]  ? exc_invalid_op+0x13/0x60\n  [1272.956700]  ? asm_exc_invalid_op+0x16/0x20\n  [1272.957011]  ? refcount_warn_saturate+0xba/0x110\n  [1272.957399]  btrfs_discard_cancel_work.cold+0x26/0x2b [btrfs]\n  [1272.957853]  btrfs_put_block_group.cold+0x5d/0x8e [btrfs]\n  [1272.958289]  btrfs_discard_workfn+0x194/0x380 [btrfs]\n  [1272.958729]  process_one_work+0x130/0x290\n  [1272.959026]  worker_thread+0x2ea/0x420\n  [1272.959335]  ? __pfx_worker_thread+0x10/0x10\n  [1272.959644]  kthread+0xd7/0x1c0\n  [1272.959872]  ? __pfx_kthread+0x10/0x10\n  [1272.960172]  ret_from_fork+0x30/0x50\n  [1272.960474]  ? __pfx_kthread+0x10/0x10\n  [1272.960745]  ret_from_fork_asm+0x1a/0x30\n  [1272.961035]  \u003c/TASK\u003e\n  [1272.961238] ---[ end trace 0000000000000000 ]---\n\nThough we have seen them in the async discard workfn as well.
