  • slirp: Reorder initialization ...
    b8e8af38 
    This patch reorders the initialization of slirp itself as well as its
associated features smb and redirection. So far the first reference to
slirp triggered the initialization, independent of the actual -net user
option which may carry additional parameters. Now we save any request to
add a smb export or some redirections until the actual initialization of
the stack. This also allows to move a few parameters that were passed
via global variable into the argument list of net_slirp_init.

  • net: Improve parameter error reporting ...
    10ae5a7a 
    As host network devices can also be instantiated via the monitor, errors
should then be reported to the related monitor instead of stderr. This
requires larger refactoring, so this patch starts small with introducing
a helper to catch both cases and convert net_client_init as well as
net_slirp_redir.

  • net: fix error reporting for some net parameter checks ...
    c8decae2 
    A small bit of confusion between buffers is causing errors like:

  qemu: invalid parameter '10' in 'script=/etc/qemu-ifup,fd=10'

instead of:

  qemu: invalid parameter 'script' in 'script=/etc/qemu-ifup,fd=10'

  • net: Real fix for check_params users ...
    0aa7a205 
    OK, last try: 8e4416af broke -net socket, ffad4116 tried to fix it
but broke error reporting of invalid parameters. So this patch widely
reverts ffad4116 again and intead fixes those callers of check_params
that originally suffered from overwritten buffers by using separate
ones.

  • Revert "Fix output of uninitialized strings" ...
    cda94b27 
    This reverts commit 8cf07dcb.

This is a sorry saga.

This commit:

  8e4416af net: Add parameter checks for VLAN clients

broken '-net socket' and this commit:

  ffad4116 net: Fix -net socket parameter checks

fixed the problem but introduced another problem which
this commit:

  8cf07dcb Fix output of uninitialized strings

fixed that final problem, but causing us to lose some
error reporting information in the process.

Meanwhile Jan posted a patch to mostly re-do ffad4116
in a way that fixes the original issue, but without
losing the error reporting information. So, let's revert
8cf07dcb and apply Jan's patch.

  • slirp: Avoid zombie processes after fork_exec ...
    7c3370d4 
    Slirp uses fork_exec for spawning service processes, and QEMU uses this
for running smbd. As SIGCHLD is not handled, these processes become
zombies on termination. Fix this by installing a proper signal handler,
but also make sure we disable the signal while waiting on forked network
setup/shutdown scripts.

  • Remove ARM NVIC initialization hack ...

    The ARMv7-M NVIC device pokes itself into the CPU state.  Now we have a
proper device model we can have the CPU/SoC code do this.

  • fix gdbstub support for multiple threads in usermode, v3 ...
    1e9fa730 
    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.
