Alright, let's try to figure out how to classify this bug report: "bsd-user dumps core for all binaries emulated". So, I'm not super familiar with QEMU, but I'll do my best. First, the user mentioned that when using bsd-user (which I think is a userspace emulation part of QEMU), any binary they run under it causes the system to dump a core file. A core dump usually happens when a program crashes, so this suggests that something is going wrong during the execution of the emulated binaries. Looking at the possible categories: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, and others. Mistranslation refers to incorrect mapping from source architecture to IR or target, typically in user-mode. Since bsd-user is part of the userspace emulation, this might be related to how instructions are being translated. If the translation is wrong, it could cause a crash leading to a core dump. Alternatively, assembly lowering could also be an issue if the assembly code generated isn't correct, causing crashes. But since the problem is specifically with bsd-user which deals more with user-mode emulation and possibly the system calls, mistranslation seems more likely. I don't think it's related to device or graphic issues because those would probably cause different kinds of errors, not necessarily core dumps on all binaries. Similarly, network or socket-related bugs might manifest in specific cases but not every binary. KVM is a hypervisor and deals with kernel-level virtualization, which isn't directly related here since we're talking about user-mode emulation. Boot issues would probably be more about starting the emulated system rather than individual binaries crashing. VNC is for remote display, so that's unlikely. Debugging tools or permissions could cause issues, but again, not in this context. Files and performance seem a bit off too unless it's related to file operations failing, but the report doesn't specify that. Putting it all together, the most fitting category seems to be "mistranslation" because it directly relates to how user-mode binaries are being translated or emulated, leading to crashes on every binary. mistranslation
