The user is reporting an issue with QEMU where the getsockopt system call behaves differently on RISC-V compared to x64 Linux. Specifically, when passing a NULL optval to getsockopt with SOL_TCP and TCP_KEEPIDLE, QEMU returns a "Bad address" error, while Linux returns 0. The man page says that passing NULL for optval is allowed if no option value is to be supplied or returned. + +Looking at the problem, the user provided a test program that compiles and runs on both platforms, showing the discrepancy. The QEMU implementation seems to be doing extra checks that the actual Linux kernel doesn't. The code in QEMU's syscall.c, specifically in the getsockopt handling, is attempting to dereference optval even when it's NULL, leading to a bad address error. The user points to the put_user*_ functions which are called even when optval is NULL, which would cause a crash. + +The core issue here is how the getsockopt syscall is handled in QEMU's user-mode emulation. The problem isn't with the instruction set or general runtime errors but specifically with the system call's implementation in QEMU. The QEMU code isn't correctly handling the case where optval is NULL as per the man page's guidance. So the category should be syscall since it's a system call handling error. +</think> + +syscall \ No newline at end of file |
