The user provided some details about their setup and the error they encountered. + +First, let me understand what's happening here. They're running a QEMU VM in a Docker container, sharing files via virtio 9p. When their test code tries to create a log file, it fails with ENOENT (No such file or directory) when setting extended attributes. + +Looking at the strace output, after creating "client.log", there's an attempt to set xattrs using lsetxattr on "/proc/self/fd/21/client.log". But this fails because the file doesn't exist in that location. The user hypothesizes that since Docker's overlayfs uses copy-on-write, the new directory version isn't accessible via the old file descriptor. + +The issue seems related to how 9pfs handles file creation and xattrs, especially when using overlayfs. The proposed fix is to modify `local_open2` in `hw/9pfs/9p-local.c` to use fsetxattr instead of lsetxattr because the current approach might not be correctly handling the file descriptors after a copy-up operation in overlayfs. + +Now, categorizing this bug. Let's go through the possible categories: + +- **mistranslation**: Incorrect semantic mapping from source to target. Doesn't seem right here; it's more about filesystem operations. +- **assembly**: Assembly lowering issues. Unlikely since it's about file handling. +- **other**: General category, but maybe too vague. +- **device**: Could relate to hardware devices, but this is more of a filesystem issue. +- **graphic**: No graphics involved. +- **socket**: Not related. +- **network**: The bug isn't in networking code per se. +- **KVM**: QEMU's hypervisor might be involved, but the issue is in 9pfs. +- **boot**: Doesn't seem to affect booting. +- **vnc**: No VNC usage mentioned. +- **debug**: Not a debug-related issue. +- **files/permissions**: This seems closer as it's about file operations and permissions. +- **performance**: Not related here. +- **kernel**: Could be, but perhaps more specific. +- **peripherals**: Maybe, but 9pfs is part of the filesystem handling, not peripherals. +- **hypervisor**: QEMU acts as a hypervisor, but again, the issue is in filesystem. + +The bug pertains to how files are created and attributes are set, which falls under file operations. Since it's related to filesystem handling within QEMU, especially with 9pfs, the most fitting category would be **files** or maybe **permissions**, but since it's about file creation failing due to incorrect xattrs after copy-up in overlayfs, I think **files** is more appropriate. +</think> + +The bug report pertains to an issue with file creation and extended attributes in a QEMU VM using 9pfs over virtio. The problem occurs when attempting to set xattrs on a newly created file, which fails due to Docker's overlayfs copy-on-write mechanism affecting the file descriptors. The suggested fix modifies how xattrs are set using fsetxattr instead of lsetxattr. + +Considering the categories provided, the bug is related to filesystem operations and handling of file descriptors, specifically when dealing with file creation and attributes. Therefore, the most appropriate category is: + +**files** \ No newline at end of file |
