6 years agosockets: avoid leak of listen file descriptor

sockets: avoid leak of listen file descriptor

If we iterate over the full port range without successfully binding+listening
on the socket, we'll try the next address, whereupon we overwrite the slisten
file descriptor variable without closing it.

Rather than having two places where we open + close socket FDs on different
iterations of nested for loops, re-arrange the code to always open+close
within the same loop iteration.

Daniel P. Berrange [Mon, 6 Nov 2017 11:08:14 +0000 (11:08 +0000)]
build: remove use of MAKELEVEL optimization in submodule handling

The Makefile attempts to optimize the handling of submodules by using MAKELEVEL
to only check the submodule status when running from the top level make
invokation. This causes problems for people who are using a makefile of their
own to in turn invoke QEMU's makefile, as MAKELEVEL is already set to 1 (or
more) when QEMU's makefile runs.

This optimization should not really be needed, since the git-submodule.sh
script is already used to detect if a submodule update is required. This by
removing the MAKELEVEL check, we at most add an extra 'git-submodule.sh status'
call to each make level, the overhead of which is lost in noise of building
QEMU.

While this is already supported, it is nice to give users a command line flag
to configure to permanently disable automatic submodule updates, as it means
they won't get hard to diagnose failures from git-submodules.sh at an arbitrary
later date.

This patch thus introduces a flag '--disable-git-update' which will prevent
'make' from ever running 'scripts/git-submodules.sh update'. It will still run
the 'status' command to determine if a submodule update is needed, but when it
does this it'll simply stop and print a message instructing the developer what

cpu-exec: Exit exclusive region on longjmp from step_atomic

Commit ac03ee5331612e44be narrowed the scope of the exclusive
region so it only covers when we're executing the TB, not when
we're generating it. However it missed that there is more than
one execution path out of cpu_tb_exec -- if the atomic insn
causes an exception then the code will longjmp out, skipping
the code to end the exclusive region. This causes QEMU to hang
the next time the CPU calls start_exclusive(), waiting for
itself to exit the region.

Move the "end the region" code out to the end of the
function so that it is run for both normal exit and also
for exit-via-longjmp. We have to use a volatile bool flag
to decide whether we need to end the region, because we
can longjump out of the codegen as well as the execution.

(For some reason this only reproduces for me with a clang
optimized build, not a gcc debug build.)

Note that when using qemu-io to test qemu-nbd behavior, it is
rather difficult to convince qemu-io to send protocol violations
(such as a read beyond bounds), because we have a lot of active
checking on the client side that a qemu-io request makes sense
before it ever goes over the wire to the server.  The case of a

monitor: fix dangling CPU pointer

If a CPU selected with the "cpu" command is hot-unplugged then "info cpus"
causes QEMU to exit:

(qemu) device_del cpu1
(qemu) info cpus
qemu:qemu_cpu_kick_thread: No such process

This happens because "cpu" stores the pointer to the selected CPU into
the monitor structure. When the CPU is hot-unplugged, we end up with a
dangling pointer. The "info cpus" command then does:

hmp_info_cpus()
 monitor_get_cpu_index()
  mon_get_cpu()
   cpu_synchronize_state() <--- called with dangling pointer

This could cause a QEMU crash as well.

This patch switches the monitor to store the QOM path instead of a
pointer to the current CPU. The path is then resolved when needed.
If the resolution fails, we assume that the CPU was removed and the

s390-ccw: print carriage return with new lines

The sclp console in the s390 bios writes raw data,
leading console emulators (such as virsh console) to
treat a new line ('\n') as just a new line instead
of as a Unix line feed. Because of this, output
appears in a "stair case" pattern.

Let's print \r\n on every occurrence of a new line
in the string passed to write to amend this issue.

This is in sync with the guest Linux code in
drivers/s390/char/sclp_vt220.c which also does a line feed
conversion in the console part of the driver.

6 years agos390x/kvm: use cpu model for gscb on compat machines
Christian Borntraeger [Fri, 20 Oct 2017 14:31:38 +0000 (16:31 +0200)]
s390x/kvm: use cpu model for gscb on compat machines

Starting a guest with
   <os>
    <type arch='s390x' machine='s390-ccw-virtio-2.9'>hvm</type>
  </os>
  <cpu mode='host-model'/>

on an IBM z14 results in

"qemu-system-s390x: Some features requested in the CPU model are not
available in the configuration: gs"

This is because guarded storage is fenced for compat machines that did
not have guarded storage support. While this prevents future migration
abort (by not starting the guest at all), not being able to start a
"host-model" guest is very much unexpected.  As it turns out, even if we
would modify libvirt to not expand the cpu model to contain "gs" for
compat machines, it cannot guarantee that a migration will succeed. For
example if the kernel changes its features (or the user has nested=1 on
one host but not on the other) the migration will fail nevertheless.  So
instead of fencing "gs" for machines <= 2.9 lets allow it for all
machine types that support the CPU model. This will make "host-model"
runnable all the time, while relying on the CPU model to reject invalid
migration attempts. We also need to change the migration for guarded
storage.
Additional discussions about host-model are still pending but are out
of scope of this patch.

target/s390x: change CPU type name to "s390x-cpu"

For now, e.g. host-s390-cpu wasn't exposed to the user. cpu-add, -cpu
and the CPU model qmp interfaces didn't care about the actual type,
as that information was hidden.

This changed with CPU hotplug via device_add. Now the type is visible to
the user. Before we get that supported in a stable version, this is our
last chance to change it.

So change it from "s390-cpu" to "s390x-cpu", to match the architecture
name. Example names are then e.g. z14-s390x-cpu or qemu-s390x-cpu.
