The IOThread object is an AioContext event loop thread. This patch adds

When SMP guests run on SMP hosts it makes sense to instantiate multiple

Note that additional patches are required to actually bind a device to

aio: add aio_context_acquire() and aio_context_release()
It can be useful to run an AioContext from a thread which normally does
not "own" the AioContext. For example, request draining can be
implemented by acquiring the AioContext and looping aio_poll() until all
requests have been completed.
The following pattern should work:
/* Event loop thread */
while (running) {
aio_context_acquire(ctx);
aio_poll(ctx, true);
aio_context_release(ctx);
}
/* Another thread */
aio_context_acquire(ctx);
bdrv_read(bs, 0x1000, buf, 1);
aio_context_release(ctx);
This patch implements aio_context_acquire() and aio_context_release().

acquiring and releasing - it is only needed when multiple threads will
call aio_poll() on the same AioContext.

QemuMutex does not guarantee fairness and cannot be acquired

Fairness means each locker gets a turn and the scheduler cannot cause

Recursive locking is useful for composition, it allows a sequence of
locking operations to be invoked atomically by acquiring the lock around
them.
This patch adds RFifoLock, a recursive lock that guarantees FIFO order.
Its first user is added in the next patch.
RFifoLock has one additional feature: it can be initialized with an
optional contention callback. The callback is invoked whenever a thread
must wait for the lock. For example, it can be used to poke the current
owner so that they release the lock soon.

tap: avoid deadlocking rx
The net subsystem has a control flow mechanism so peer NetClientStates
can tell each other to stop sending packets. This is used to stop
monitoring the tap file descriptor for incoming packets if the guest rx
ring has no spare buffers.
There is a corner case when tap_can_send() is true at the beginning of
an event loop iteration but becomes false before the tap_send() fd
handler is invoked.
tap_send() will read the packet from the tap file descriptor and attempt
to send it. The net queue will hold on to the packet and return 0,
indicating that further I/O is not possible. tap then stops monitoring
the file descriptor for reads.
This is unlike the normal case where tap_can_send() is the same before
and during the event loop iteration. The event loop would simply not
monitor the file descriptor if tap_can_send() returns true. Upon next
iteration it would check tap_can_send() again and begin monitoring if we
can send.
The deadlock happens because tap_send() explicitly disabled read_poll.
This is done with the expectation that the peer will call
qemu_net_queue_flush(). But hw/net/virtio-net.c does not monitor
vm_running transitions and issue the flush. Hence we're left with a
broken tap device.

slirp smb with modern win guests when samba is also running on host
After numerous reports that -smb (or -netdev user,smb=foo) not working
with modern windows (win7 and vista are reported as non-working), I
started digging myself. And found that indeed it doesn't work, and
why.
The thing is that modern win tries to connect to port 445 (microsoft-ds)
first, and if that fails, it falls back to old port 139 (netbios-ssn).
slirp code in qemu only redirects port 139, it does not touch port 445.
So the prob is that if samba is also running on the host, guest will try
to communicate using port 445, and that will succed, but ofcourse guest
will not talk with our samba but with samba running on the host.
If samba is not running on the host, guest will fall back to port 139,
and will reach the redirecting rule and qemu will spawn smbd correctly.
The solution is to redirect both ports (139 and 445), and the fix is
a one-liner, adding second call to slirp_add_exec() at the end of
net/slirp.c:slirp_smb() function (provided below).
But it looks like that is not a proper fix really, since in theory
we should redirect both ports to the SAME, single samba instance,
but I'm not sure this is possible with slirp. Well, even if two
smbd processes will be run on the same config dir, it should not
be a problem.
The one-liner (not exactly 1 since it touches previous line too) is like
this:

qemu/slirp: Fix SMB security configuration on newer samba versions
The smb.conf automatically generated by qemu's -smb option fails on current
samba, because smbd rejects the security=share option with the following warning:
> WARNING: Ignoring invalid value 'share' for parameter 'security'
Which makes it fall back to security=user without guest login.
This results in being unable to login to the samba server from the guest OS.
This fixes it by selecting 'user' explicitly and mapping
unknown users to guest logins.

target-sparc: Add and use CPU_FEATURE_CASA
The LEON3 processor has support for the CASA instruction which is
normally only available for SPARC V9 processors. Binutils 2.24
and GCC 4.9 will support this instruction for LEON3. GCC uses it to
generate C11 atomic operations.
The CAS synthetic instruction uses an ASI of 0x80. If TARGET_SPARC64 is
not defined use a supervisor data load/store for an ASI of 0x80 in
helper_ld_asi()/helper_st_asi(). The supervisor data load/store was
choosen according to the LEON3 documentation.
The ASI 0x80 is defined in the SPARC V9 manual, Table 12—Address Space
Identifiers (ASIs). Here we have: 0x80, ASI_PRIMARY, Unrestricted
access, Primary address space.
Tested with the following program:
#include <assert.h>
#include <stdatomic.h>
void test(void)
{
atomic_int a;
int e;
_Bool b;
atomic_store(&a, 1);
e = 1;
b = atomic_compare_exchange_strong(&a, &e, 2);
assert(b);
assert(atomic_load(&a) == 2);
atomic_store(&a, 3);
e = 4;
b = atomic_compare_exchange_strong(&a, &e, 5);
assert(!b);
assert(atomic_load(&a) == 3);
}
Tested also on a NGMP board with a LEON4 processor.
