The user is describing an issue where a background job in a bash shell under QEMU's RISC-V32 user-mode emulation hangs indefinitely. The problem seems to be related to wait4 or waitpid returning incorrect values. The strace output shows repeated waitid calls returning 0, which might indicate that the parent process isn't properly being notified of the child's status. + +The user provided a simple_shell.c example that's supposed to handle background jobs. When running this under QEMU, after launching a background process like ./loop &, the wait4 call returns a non-zero value (98298) instead of 0 as expected on other architectures. This suggests that the wait4 syscall isn't behaving correctly in the RISC-V32 emulation environment. + +Since the issue is about the system call (wait4/waitpid) not returning the correct value, leading to incorrect behavior in process management, this points to a syscall-related problem. The problem isn't with the instruction set itself (which would be 'instruction'), nor is it a general runtime error. It's specifically about how the syscall is handled in QEMU's user-mode emulation. + +Looking at the QEMU bug categories provided, 'syscall' is the right classification here. The core issue is the incorrect handling or return value of the wait4 system call in the RISC-V32 emulation context. +</think> + +syscall \ No newline at end of file |
