The user mentioned that when using execveat with an empty filename and AT_EMPTY_PATH flag on different architectures like arm64, arm, riscv64, etc., it returns ENOENT (No such file or directory). However, for x86_64 and x86, it works fine. + +First, I need to understand what's happening here. execveat is a system call that allows executing a program from a file descriptor. The AT_EMPTY_PATH flag tells the kernel that the filename is empty, meaning the path comes from the file descriptor provided. On some architectures, this isn't working as expected. + +The user also mentioned using binfmt_misc which is used to register interpreters for different binary formats (like QEMU for running foreign binaries). When binfmt_misc is enabled, it allows these foreign binaries to run by translating them on-the-fly. + +Looking at the test cases: +- For x86_64 and x86, everything works fine when using execveat with AT_EMPTY_PATH. +- For other architectures (aarch64, riscv64), it fails with ENOENT when using AT_EMPTY_PATH but works if they use /proc/self/fd/%d as the pathname. + +The error seems to be happening in how the system call is handled for different architectures. Since execveat is a syscall and this behavior varies across architectures, especially when using QEMU's binfmt_misc setup, it points towards an issue with how the system handles foreign binaries or specific syscalls under QEMU. + +The possible categories given are instruction, syscall, runtime. The problem here isn't about faulty instructions in the code (so not 'instruction'). It also doesn't seem to be a general runtime error unrelated to system calls. Instead, it's specifically about the execveat system call failing under certain conditions when running different architectures with QEMU. + +Therefore, this bug falls under the 'syscall' category because it's related to how the execveat system call is being handled or emulated by QEMU for foreign architectures. +</think> + +The issue arises from how the `execveat` system call is being processed for different architectures within QEMU. The error occurs specifically when using this syscall with an empty path and AT_EMPTY_PATH flag, which works for some arches but not others. This indicates a problem in handling syscalls across various architectures. + +**Answer:** syscall \ No newline at end of file |
