Heyi Guo cf48a9052e arm/virt/acpi: remove meaningless sub device "RP0" from PCI0
The sub device "RP0" under PCI0 in ACPI/DSDT does not contain any
method or property other than "_ADR", so it is safe to remove it.

Dr. David Alan Gilbert 6e1f837a14 tests/migration: Add some slack to auto converge
There's an assert in autoconverge that checks that we quit the
iteration when we go below the expected threshold.  Philippe
saw a case where this assert fired with the measured value
slightly over the threshold. (about 3k out of a few million).

I can think of two reasons:
  a) Rounding errors
  b) That after we make the decision to quit iteration we do one
    more sync and that sees a few more dirty pages.

So add 1% slack to the assertion, that should cover a and
most cases of b, probably all we'll see for the test.

Keqian Zhu d05de9e39a migration: Optimization about wait-unplug migration state
qemu_savevm_nr_failover_devices() is originally designed to
get the number of failover devices, but it actually returns
the number of "unplug-pending" failover devices now. Moreover,
what drives migration state to wait-unplug should be the number
of "unplug-pending" failover devices, not all failover devices.

We can also notice that qemu_savevm_state_guest_unplug_pending()
and qemu_savevm_nr_failover_devices() is equivalent almost (from
the code view). So the latter is incorrect semantically and
useless, just delete it.

In the qemu_savevm_state_guest_unplug_pending(), once hit a
unplug-pending failover device, then it can return true right
now to save cpu time.

The only difference to hardware revision 4 is that the device doesn't
switch to VGA mode in case someone happens to touch a VGA register,
which should make things more robust in configurations with multiple

Swtiching back to VGA mode happens on reset, either full machine
reset or qxl device reset (QXL_IO_RESET ioport command).

Laurent Vivier 6d485a55d0 linux-user: implement TARGET_SO_PEERSEC
"The purpose of this option is to allow an application to obtain the
security credentials of a Unix stream socket peer.  It is analogous to
SO_PEERCRED (which provides authentication using standard Unix credentials
of pid, uid and gid), and extends this concept to other security
models." -- https://lwn.net/Articles/62370/

Until now it was passed to the kernel with an "int" argument and
fails when it was supported by the host because the parameter is
like a filename: it is always a \0-terminated string with no embedded
\0 characters, but is not guaranteed to be ASCII or UTF-8.

I've tested the option with the following program:

    /*
     * cc -o getpeercon getpeercon.c
     */

    #include <stdio.h>
    #include <sys/types.h>
    #include <sys/socket.h>
    #include <netinet/in.h>
    #include <arpa/inet.h>

    int main(void)
    {
        int fd;
        struct sockaddr_in server, addr;
        int ret;
        socklen_t len;
        char buf[256];

        fd = socket(PF_INET, SOCK_STREAM, 0);
        if (fd == -1) {
            perror("socket");
            return 1;
        }

        server.sin_family = AF_INET;
        inet_aton("127.0.0.1", &server.sin_addr);
        server.sin_port = htons(40390);

        connect(fd, (struct sockaddr*)&server, sizeof(server));

        len = sizeof(buf);
        ret = getsockopt(fd, SOL_SOCKET, SO_PEERSEC, buf, &len);
        if (ret == -1) {
            perror("getsockopt");
            return 1;
        }
        printf("%d %s\n", len, buf);
        return 0;
    }

On host:

  $ ./getpeercon
  33 system_u:object_r:unlabeled_t:s0

With qemu-aarch64/bionic without the patch:

  $ ./getpeercon
  getsockopt: Numerical result out of range

With the patch:

  $ ./getpeercon
  33 system_u:object_r:unlabeled_t:s0

Laurent Vivier 6bc024e713 linux-user: fix use of SIGRTMIN
Some RT signals can be in use by glibc,
it's why SIGRTMIN (34) is generally greater than __SIGRTMIN (32).

So SIGRTMIN cannot be mapped to TARGET_SIGRTMIN.

Instead of swapping only SIGRTMIN and SIGRTMAX, map all the
range [TARGET_SIGRTMIN ... TARGET_SIGRTMAX - X] to
      [__SIGRTMIN + X ... SIGRTMAX ]
(SIGRTMIN is __SIGRTMIN + X).

Even though MSR_IA32_UCODE_REV has been available long before Linux 5.6,
which added it to the emulated MSR list, a bug caused the microcode

some Windows version complain loudly about this and crash with a
fairly explicit MICROCODE REVISION MISMATCH error.

 microcode version on INIT or RESET" should also be applied.]

deal with this. However, more recently (notably in commit
50290c002c for qemu-img in mid-2019, but also much
earlier in 2011 in commit 22795174a3 for ui/spice-display.c)
we've written code that assumes CLOCK_MONOTONIC is always
defined. The only host OS anybody's ever noticed this on
is OSX 10.11 and earlier, which we don't support.

So we can assume that all our host OSes have the #define,
and we can remove some now-unnecessary ifdefs.

Luc Michel e261b36810 seqlock: fix seqlock_write_unlock_impl function
The seqlock write unlock function was incorrectly calling
seqlock_write_begin() instead of seqlock_write_end(), and was releasing
the lock before incrementing the sequence. This could lead to a race
condition and a corrupted sequence number becoming odd even though the
lock is not held.

Peter Maydell 483644c25b ui/cocoa: Drop workarounds for pre-10.12 OSX
Our official OSX support policy covers the last two released versions.
Currently that is 10.14 and 10.15.  We also may work on older versions, but
don't guarantee it.

In commit 50290c002c in mid-2019 we introduced some uses of
CLOCK_MONOTONIC which incidentally broke compilation for pre-10.12 OSX
versions (see LP:1861551). We don't intend to fix that, so we might
as well drop the code in ui/cocoa.m which caters for pre-10.12
versions as well. (For reference, 10.11 fell out of Apple extended
security support in September 2018.)

Max Filippov b55f54bc96 exec: flush CPU TB cache in breakpoint_invalidate
When a breakpoint is inserted at location for which there's currently no
virtual to physical translation no action is taken on CPU TB cache. If a
TB for that virtual address already exists but is not visible ATM the
breakpoint won't be hit next time an instruction at that address will be
executed.

Flush entire CPU TB cache in breakpoint_invalidate to force
re-translation of all TBs for the breakpoint address.

This change fixes the following scenario:
- linux user application is running
- a breakpoint is inserted from QEMU gdbstub for a user address that is
  not currently present in the target CPU TLB
- an instruction at that address is executed, but the external debugger
  doesn't get control.
