Together with the debian-bootstrap.pre script can now build an arbitrary
architecture of Debian using debootstrap. This allows debootstrap to set
up its first stage before the container is built.
To build a container you need a command line like:
DEB_ARCH=armhf DEB_TYPE=testing \
./tests/docker/docker.py build \
--include-executable=arm-linux-user/qemu-arm debian:armhf \
./tests/docker/dockerfiles/debian-bootstrap.docker
Although a number of non-debian systems package the debootstrap script
it is fairly portable in itself. Assuming we have some sort of fakeroot
implementation we can just clone the upstream repository and use the
script from there.

When passed the path to a binary we copy it and any linked libraries (if

ADD . /
This is mainly intended for setting up foreign architecture docker
images which use qemu-$arch to do cross-architecture linux-user
execution. It also relies on the host and guest file-system following
reasonable multi-arch layouts so the copied libraries don't clash with

This patch adds a way to specify multiple volfile servers to the gluster
block backend of QEMU with tcp|rdma transport types and their port numbers.
Problem:
Currently VM Image on gluster volume is specified like this:
file=gluster[+tcp]://host[:port]/testvol/a.img
Say we have three hosts in a trusted pool with replica 3 volume in action.
When the host mentioned in the command above goes down for some reason,
the other two hosts are still available. But there's currently no way
to tell QEMU about them.
Solution:
New way of specifying VM Image on gluster volume with volfile servers:
(We still support old syntax to maintain backward compatibility)
Basic command line syntax looks like:
Pattern I:
-drive driver=gluster,
volume=testvol,path=/path/a.raw,[debug=N,]
server.0.type=tcp,
server.0.host=1.2.3.4,
server.0.port=24007,
server.1.type=unix,
server.1.socket=/path/socketfile
Pattern II:
'json:{"driver":"qcow2","file":{"driver":"gluster",
"volume":"testvol","path":"/path/a.qcow2",["debug":N,]
"server":[{hostinfo_1}, ...{hostinfo_N}]}}'
driver => 'gluster' (protocol name)
volume => name of gluster volume where our VM image resides
path => absolute path of image in gluster volume
[debug] => libgfapi loglevel [(0 - 9) default 4 -> Error]
{hostinfo} => {{type:"tcp",host:"1.2.3.4"[,port=24007]},
{type:"unix",socket:"/path/sockfile"}}
type => transport type used to connect to gluster management daemon,
it can be tcp|unix
host => host address (hostname/ipv4/ipv6 addresses/socket path)
port => port number on which glusterd is listening.
socket => path to socket file
Examples:
1.
-drive driver=qcow2,file.driver=gluster,
file.volume=testvol,file.path=/path/a.qcow2,file.debug=9,
file.server.0.type=tcp,
file.server.0.host=1.2.3.4,
file.server.0.port=24007,
file.server.1.type=unix,
file.server.1.socket=/var/run/glusterd.socket
2.
'json:{"driver":"qcow2","file":{"driver":"gluster","volume":"testvol",
"path":"/path/a.qcow2","debug":9,"server":
[{"type":"tcp","host":"1.2.3.4","port":"24007"},
{"type":"unix","socket":"/var/run/glusterd.socket"}
]}}'
This patch gives a mechanism to provide all the server addresses, which are in
replica set, so in case host1 is down VM can still boot from any of the
active hosts.
This is equivalent to the backup-volfile-servers option supported by
mount.glusterfs (FUSE way of mounting gluster volume)

gluster volfile server fetch happens through unix and/or tcp, it doesn't
support volfile fetch over rdma. The rdma code may actually mislead,
so to make sure things do not break, for now we fallback to tcp when requested
for rdma, with a warning.
If you are wondering how this worked all these days, its the gluster libgfapi
code which handles anything other than unix transport as socket/tcp, sad but
true.
Also gluster doesn't support ipv6 addresses, removing the ipv6 related
comments/docs section

There are 2 deficiencies here:
- mirror_iteration could start several requests inside. Thus we could
simply have more in_flight requests than MAX_IN_FLIGHT.
- keeping this in mind throttling in mirror_run which is checking
s->in_flight == MAX_IN_FLIGHT is wrong.
The patch adds the check and throttling into mirror_iteration and fixes
the check in mirror_run() to be sure.

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

Coverity complains that the GICR_IPRIORITYR case in gicv3_readl()
can overflow an array, because it doesn't know that the offsets
passed to that function must be word aligned. Add some assert()s
which hopefully tell Coverity that this isn't possible.

Coverity complains that the exit() in gicv3_class_name()
can be unreachable, because if TARGET_AARCH64 is defined
then all code paths return before reaching it. Move the
exit() up to the error_report() that it belongs with.

disas/bfd.h defines ATTRIBUTE_UNUSED, but unfortunately the
ALSA system headers also define this macro, which means that
you can get a compilation failure if building with ALSA and
any files happen to include the alsa headers before bfd.h
rather than the other way around.
This is unfortunate namespace pollution by the ALSA headers but
we can work around it. Add an #ifndef guard to bfd.h and remove
the unnecessary extra definition in disas/arm.c to fix this.

The AArch64 Linux ABI syscall 84 is sync_file_range, not
sync_file_range2 (in the kernel it uses the asm-generic
headers and does not define __ARCH_WANT_SYNC_FILE_RANGE2).
Update our TARGET_NR_* definitions accordingly.
This fixes the sync_file_range syscall which otherwise
gets its arguments in the wrong order.

The SIOCATMARK ioctl takes an argument which should be a
pointer to an integer where the kernel will write the result.
We were incorrectly declaring it as TYPE_NULL which would mean
it would always fail (with EFAULT) when it should succeed.
Correct the type.

TIOCGPTN and related terminal control ioctls were not converted to the guest ioctl format on x86_64 targets. Convert these ioctls to enable terminal functionality on x86_64 guests.

Add some new blk ioctls (these are 0x12,119 through
to 0x12,127). Several of these are used by mke2fs; this silences
the warnings:

If userspace specifies a short buffer for a target sockaddr,
the kernel will only copy in as much as it has space for
(or none at all if the length is zero) -- see the kernel
move_addr_to_user() function. Mimic this in QEMU's
host_to_target_sockaddr() routine.
In particular, this fixes a segfault running the LTP
recvfrom01 test, where the guest makes a recvfrom()
call with a bad buffer pointer and other parameters which
cause the kernel to set the addrlen to zero; because we
did not skip the attempt to swap the sa_family field we
segfaulted on the bad address.

Commit 655ed67c2a which switched synchronous signals to
benig recorded in ts->sync_signal rather than in a queue
with every other signal had a bug: we failed to clear
the flag indicating that a synchronous signal was pending
when we delivered it. This meant that we would take the signal
again and again every time the guest made a syscall.
(This is a bug introduced in my refactoring of Timothy Baldwin's
original code.)
Fix this by passing in the struct emulated_sigtable* to
handle_pending_signal(), so that we clear the pending flag
in the ts->sync_signal struct when handling a synchronous signal.
