Title
udf: Mark LVID buffer as uptodate before marking it dirty
Summary
In the Linux kernel, the following vulnerability has been resolved: udf: Mark LVID buffer as uptodate before marking it dirty When an I/O error occurs while writing the Logical Volume Integrity Descriptor (LVID) buffer to the block device, the block layer's completion handler (`end_buffer_write_sync()`) clears the `BH_Uptodate` flag on the buffer. However, the buffer still contains valid LVID data in memory. If the filesystem is subsequently remounted read-write or synced, `udf_open_lvid()` or `udf_sync_fs()` will modify the LVID buffer and call `mark_buffer_dirty()`. This triggers a spurious `WARN_ON_ONCE(!buffer_uptodate(bh))` warning in `mark_buffer_dirty()` because the buffer is not marked uptodate, even though its in-memory contents are valid and are about to be overwritten. To prevent this spurious warning, unconditionally set the `BH_Uptodate` flag before calling `mark_buffer_dirty()` in `udf_open_lvid()` and `udf_sync_fs()`. This acknowledges that the in-memory buffer is valid and matches the workaround previously applied to `udf_close_lvid()` in commit 853a0c25baf9 ("udf: Mark LVID buffer as uptodate before marking it dirty"). Extending this workaround ensures consistent behavior across all LVID updates.

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nudf: Mark LVID buffer as uptodate before marking it dirty\n\nWhen an I/O error occurs while writing the Logical Volume Integrity\nDescriptor (LVID) buffer to the block device, the block layer\u0027s completion\nhandler (`end_buffer_write_sync()`) clears the `BH_Uptodate` flag on the\nbuffer. However, the buffer still contains valid LVID data in memory. If\nthe filesystem is subsequently remounted read-write or synced,\n`udf_open_lvid()` or `udf_sync_fs()` will modify the LVID buffer and call\n`mark_buffer_dirty()`. This triggers a spurious\n`WARN_ON_ONCE(!buffer_uptodate(bh))` warning in `mark_buffer_dirty()`\nbecause the buffer is not marked uptodate, even though its in-memory\ncontents are valid and are about to be overwritten.\n\nTo prevent this spurious warning, unconditionally set the `BH_Uptodate`\nflag before calling `mark_buffer_dirty()` in `udf_open_lvid()` and\n`udf_sync_fs()`. This acknowledges that the in-memory buffer is valid and\nmatches the workaround previously applied to `udf_close_lvid()` in commit\n853a0c25baf9 (\"udf: Mark LVID buffer as uptodate before marking it dirty\").\nExtending this workaround ensures consistent behavior across all LVID\nupdates.\n\nBuffer I/O error on dev loop0, logical block 128, lost sync page write\n------------[ cut here ]------------\n!buffer_uptodate(bh)\nWARNING: fs/buffer.c:1087 at mark_buffer_dirty+0x299/0x410 fs/buffer.c:1087\n...\nCall Trace:\n \u003cTASK\u003e\n udf_open_lvid+0x369/0x5b0 fs/udf/super.c:2078\n udf_reconfigure+0x336/0x540 fs/udf/super.c:679\n reconfigure_super+0x232/0x8f0 fs/super.c:1080\n vfs_cmd_reconfigure fs/fsopen.c:268 [inline]\n vfs_fsconfig_locked+0x171/0x320 fs/fsopen.c:297\n __do_sys_fsconfig fs/fsopen.c:463 [inline]\n __se_sys_fsconfig+0x6b9/0x810 fs/fsopen.c:350\n do_syscall_64+0x174/0x580 arch/x86/entry/syscall_64.c:94\n \u003c/TASK\u003e"
