The issue is about running a 32-bit binary under a 64-bit QEMU environment. Specifically, the problem occurs when using AddressSanitizer (Asan), which fails because it can't find stack boundaries. + +The user provided code that demonstrates the issue by compiling a simple C program with Asan and running it in QEMU. The error message shows an AddressSanitizer check failing due to incorrect mapping information. They traced this back to the QEMU code, specifically the open_self_maps function in linux-user/syscall.c. + +Looking at the code snippet provided, I see that QEMU is conditionally adding stack boundaries only for certain architectures (ARM, M68K, UNICORE32). This means that for other targets like x86_64 or i386, the stack isn't being properly reported in /proc/self/maps. + +Since this problem arises from how QEMU emulates user-space processes and their memory mappings, it seems related to user-mode emulation. User-mode deals with executing guest programs and handling their system calls and memory spaces, which is where the issue is occurring. + +Moreover, the bug affects how Asan initializes within the guest process, which is a user-level tool used for debugging. This further indicates that the problem lies in the user-mode part of QEMU rather than the system-mode aspects like device emulation or higher-privilege operations. + +So, putting it all together, this bug is related to user-mode because it's about how QEMU handles memory mappings and stack information for guest programs executing in user space. +</think> + +user \ No newline at end of file |
