Remote GDB debugging X8664_Linux occurs warning: Invalid remote reply: #1377

Open Alsoprach opened 1 year ago

Alsoprach commented 1 year ago

*Describe the bug When qiling runs the x8664_linux program and enables default GDB remote debugging, two n/si instructions issued by GDB will trigger warning: Invalid remote reply, causing debugging to fail. But the breakpoint-based c instruction is normal.

Sample Code

import sys
from qiling import *
from qiling.extensions import pipe
from qiling.const import QL_VERBOSE

def test_gdb(path, rootfs):
    ql = Qiling(path, rootfs, verbose=QL_VERBOSE.DEBUG,log_file="./output")
    ql.debugger = True
    ql.run()  

if __name__ == "__main__":
    test_gdb(["../tool/qiling/examples/rootfs/x8664_linux/bin/pwn1"], "../tool/qiling/examples/rootfs/x8664_linux")

Expected behavior Remote gdb can debug normally without restriction.

The last incoming command is vCont;S0f:pa410.1996;c:pa410.-1. Since vCont support is limited, Qiling doesn't know how to handle the S0f command and fails. We should fix that.

Thank you for your reply

I'm also experiencing this issue. Is there any fix or workaround for it? Would running on a compatible VM or using a different debugger solve the issue, and if so, what do you suggest to try?

Here is the last bit of my log - seems to break on the same command:

Same issue here, usually if I try to do anything (step, continue, etc) after hitting a breakpoint I get a SIGTERM disconnect.
