The problem is about QEMU's i386 emulator not correctly decoding the arguments for the old mmap syscall (number 90) on 32-bit. The user provided a test case where when running with strace, the mmap call shows the correct arguments, but when using QEMU's -strace option, the arguments reported are different. + +Looking at the assembly code, they're setting up the stack with the six arguments for the mmap syscall. The comment mentions that %ebx points to the array of six arguments. The syscall number is 90 for mmap. The issue is that QEMU isn't reporting the correct arguments when tracing. + +The problem seems to be that QEMU is not properly interpreting the syscall arguments. The user's test case shows that the actual arguments passed (like NULL, 8192, PROT_READ|PROT_WRITE, etc.) are captured correctly by the host strace but not by QEMU's own tracing. That suggests that QEMU's code for handling the mmap syscall's argument extraction is incorrect. + +Since syscalls are the interface between user space and kernel, and QEMU emulates the system calls for the guest program, any error in how the arguments are read or passed would fall under a syscall error. The bug isn't about an incorrect CPU instruction (so not 'instruction'), nor is it a general runtime error (so not 'runtime'). It's specifically about the syscall arguments being misinterpreted by QEMU. Therefore, this is a syscall category issue. +</think> + +syscall \ No newline at end of file |
