Let me go through the information provided step by step. + +First, the problem occurs when running a specific program under QEMU's user emulation. The program is using pthread_getattr_np(), which is a non-portable (GNU) extension to get thread attributes. When this function is called, QEMU crashes with a segmentation fault, specifically SIGSEGV at address 0x20. + +Looking at the backtrace from GDB, it shows that the crash happens in several functions within QEMU's codebase. The stack trace goes through functions like open_self_maps_2, walk_memory_regions, and eventually into do_syscall1 and do_syscall. These function names suggest that the issue is related to system calls being handled by QEMU. + +The user also mentioned that this bug was introduced after a rewrite of the `open_self_maps` function in commit 7b7a3366e142d3baeb3fd1d3660a50e7956c19eb. That indicates that there's something wrong with how QEMU is handling this specific system call or related memory operations. + +Now, considering the possible categories: instruction, syscall, runtime. + +- **Instruction**: This would be if the issue was caused by a faulty CPU instruction. But here, the problem arises from a system call, not directly from an executed instruction. + +- **Syscall**: Since the crash happens during a system call handling in QEMU, specifically when opening `/proc/self/maps`, which is part of process memory management. The error seems to stem from how QEMU processes this syscall, leading to invalid memory access. + +- **Runtime**: This would cover other runtime errors not related to instructions or syscalls, but given the stack trace points directly to system call handling functions, it's more specific than a general runtime issue. + +Therefore, the bug is likely related to how QEMU handles a particular system call, which fits into the "syscall" category. The crash occurs during the processing of an openat system call (as seen in do_guest_openat), leading to invalid memory access and segmentation fault. +</think> + +syscall \ No newline at end of file |
