The issue is about the `execveat` system call returning ENOENT when using a file descriptor and an empty filename with certain architectures. + +First, let me understand what's happening here. The user reports that on their x86_64 Debian host with binfmt_misc configured, calling `execveat` with a file descriptor (fd), an empty pathname "", and the flag AT_EMPTY_PATH works for x86_64 and x86 programs but fails for other architectures like arm64, arm, riscv64, etc. It returns ENOENT, which means "No such file or directory." + +They mentioned that when using `fexecve` from LXC, they encountered this problem. They also provided a test case where running the test binary directly (like with qemu-aarch64) gives an error when using AT_EMPTY_PATH but works if the path is /proc/self/fd/3 instead. + +So, what's happening here? The `execveat` system call allows specifying file descriptors and flags. The AT_EMPTY_PATH flag tells the kernel to interpret an empty pathname as referring to the fd itself, rather than needing a filename. But for some architectures, this isn't working, leading to ENOENT. + +Looking at possible categories: mistranslation is about incorrect semantic mapping from source architecture to target. Since QEMU emulates other architectures on x86_64, if the bug occurs during this translation process, it might be a mistranslation issue. + +Assembly lowering (assembly) refers to converting high-level code to assembly, which doesn't seem directly related here. The problem is more about system call handling across different architectures. + +Other categories like device, graphic, socket, etc., don't fit as the issue is with syscalls and cross-architecture execution. + +So, considering that `execveat` is a syscall handled by the kernel but in QEMU's context, it might be related to how QEMU translates these syscalls for different architectures. If QEMU isn't correctly handling the AT_EMPTY_PATH flag when translating from x86_64 to other archs like arm64, that would fall under mistranslation. + +I think the category here is "mistranslation." +</think> + +The bug report describes an issue where `execveat` with a file descriptor and empty filename returns ENOENT for certain architectures. This points to a problem in how QEMU translates system calls across different architectures, likely during the handling of the AT_EMPTY_PATH flag. + +**Answer:** mistranslation \ No newline at end of file |
