Let me go through the information step by step. + +The user provided a description where using strace with QEMU shows incorrect decoding of the writev system call arguments for 64-bit binaries on a 32-bit machine. The steps to reproduce include compiling the same code for different architectures and then running them under QEMU with strace. When they run strace, the output for writev is wrong in certain cases. + +Looking at the outputs: + +- For i686-main (32-bit), strace shows correct decoding. +- For x86_64-main (64-bit on a 64-bit host), strace also shows correct decoding with the nil pointer and address. +- But when using qemu-i386 --strace on the i686-main, it incorrectly decodes the arguments as addresses instead of showing the actual data. Similarly, for aarch64, it's not showing correctly. + +So the problem seems to be that QEMU is misinterpreting how the writev system call's arguments are being passed when running 64-bit binaries on a 32-bit emulator with --strace. This affects how strace displays the arguments, making them look like memory addresses instead of the actual data structures. + +Now, I need to categorize this bug. The options are instruction, syscall, or runtime. + +- Instruction: If it were an issue with a specific CPU instruction being wrong. +- Syscall: An error in handling system calls, possibly misinterpretation of parameters. +- Runtime: Other runtime errors not related to instructions or syscalls. + +This seems to be a problem with how QEMU handles the decoding of system call arguments for writev when using --strace. Since writev is a syscall and the issue arises during its processing under strace, it's likely a syscall-related error in the emulation. The incorrect display suggests that the arguments are not being parsed correctly by the strace mechanism in QEMU. + +So I think this falls under 'syscall' because it involves misdecoding the parameters of a system call when tracing. +</think> + +The bug report is about incorrect decoding of writev's arguments during --strace, which relates to how syscalls are handled. + +syscalls \ No newline at end of file |
