Nathan Froyd [Wed, 3 Jun 2009 18:33:08 +0000 (11:33 -0700)]
fix gdbstub support for multiple threads in usermode, v3

When debugging multi-threaded programs, QEMU's gdb stub would report the
correct number of threads (the qfThreadInfo and qsThreadInfo packets).
However, the stub was unable to actually switch between threads (the T
packet), since it would report every thread except the first as being
dead.  Furthermore, the stub relied upon cpu_index as a reliable means
of assigning IDs to the threads.  This was a bad idea; if you have this
sequence of events:

initial thread created
new thread #1
new thread #2
thread #1 exits
new thread #3

thread #3 will have the same cpu_index as thread #1, which would confuse
GDB.  (This problem is partly due to the remote protocol not having a
good way to send thread creation/destruction events.)

We fix this by using the host thread ID for the identifier passed to GDB
when debugging a multi-threaded userspace program.  The thread ID might
wrap, but the same sort of problems with wrapping thread IDs would come
up with debugging programs natively, so this doesn't represent a
problem.

Fix output of uninitialized strings

Commit ffad4116b96e29e0fbe892806f97c0a6c903d30d removed the "scratch buffer"
from check_params, but didn't care for the error messages which actually
included this string to tell the user which option was wrong. Now this string
is uninitialized, so this patch removes it from the message.

This means that the user is only told the whole parameter string and has to
pick the wrong option by himself as the callers of check_params can't know this
value any more. An alternative approach would be to revert that commit and do
whatever is needed to fix the original problem without changing check_params.
