Hi, I was skimming the list, and noticed:

This looks like it'd mishandle a future qAttached2 packet.

It should be doing something like:

       if (strncmp(p, "Attached", 8) == 0 &&
          (p[8] == '\0' || p[8] == ':')) {

or:

       if (strcmp(p, "Attached") == 0 || strncmp(p, "Attached:", 9) == 0) {


Likewise other packets, if they have the same issue.
(I'm not familiar with qemu's stub's internals.)

Thanks,
Pedro Alves
