2025-09-13libfuse: fix COPY_FILE_RANGE interfaceMiklos Szeredi-6/+73
The FUSE protocol uses struct fuse_write_out to convey the return value of copy_file_range, which is restricted to uint32_t. But the COPY_FILE_RANGE interface supports a 64-bit size copies. Currently the number of bytes copied is silently truncated to 32-bit, which is unfortunate at best. Implement the COPY_FILE_RANGE_64 interface which is identical to the old one, except the number of bytes copied is returned in a 64-bit value. The library interface remains the same. If the kernel does not support the new interface or the server is running as a 32-bit process, limit the copy size to size to UINT_MAX - 4096. Edit by Bernd: Keep ioctl_64bit and add use new bit is_copy_file_range_64 to keep flags separated from each other - easier code readability IMO.

2025-07-21example/memfs_ll: Avoid nullptr field initializations by pragmaBernd Schubert-29/+3
These nullptr initializations don't make sense - methods that are not explicitly set are not implemented. I thought that C++20 would eventually avoid the nullptr, but looks like compilers still give warnings - avoid them with a pragma. Signed-off-by: Bernd Schubert <bschubert@ddn.com>
2025-07-16memfs_ll: fix deadlock in truncate operationLong Li-1/+0
Remove redundant mutex lock acquisition in the truncate() method to prevent deadlock. The issue occurs when memfs_setattr() already holds the mutex lock and then calls truncate(), which attempts to acquire the same lock again. Signed-off-by: Long Li <leo.lilong@huawei.com>
2025-07-16Avoid double unmount on FUSE_DESTROYBernd Schubert-12/+24
This is a long standing issue, a system could have unmounted /path/to/mnt and then fuse-client/kernel would send FUSE_DESTROY, which would then again try a umount. Given that FUSE_DESTROY is async, that umount might arrive any time later and might possibly unmount a wrong mount point. A warning as in issue #1286 is just minor to that. Code wise this uses atomics to free the char *, as FUSE_DESTROY might race with a signal and a double free might be possible without proctection. A lock might run into the same issue, if the signal would arrive at the wrong time a double lock would be possible. Additionally, fuse_session_mount() is updated, to first duplicatate the pointer and to then do the kernel mount - reverting the kernel mount in case of strdup() failure is much harder.

This commit adds libfuse support for FUSE_STATX requests on linux distributions. Currently, statx is only supported on linux.
