Laine Stump 7038322991 docs: point out git send-email location, be more stern about make check
An email came to libvir-list wondering why the git send-email command
was missing in spite of having git installed; this is due to the
send-email command being in a sub-package of the main git package.

While touching the hacking file, I thought it would be useful to 1)
indicate the location of the source (docs/hacking.html.in) in the
message at the top of HACKING, and also to make the note about running
"make check" and "make syntax-check" a bit more stern.

Eric Blake 892242519a build: fix build on older gcc
On RHEL 6.2, gcc 4.4.6 complains:
cc1: warning: command line option "-Wenum-compare" is valid for C++/ObjC++ but not for C
which in turn breaks a -Werror build.

Meanwhile, in Fedora 17, gcc 4.7.0, -Wenum-compare has been enhanced
to also work on C, but at the same time, it is documented that -Wall
now implicitly includes -Wenum-compare.

Therefore, it is sufficient to remove explicit checks for this option,
avoiding the warning from older gcc while still getting the
compile-time safety from newer gcc.

* m4/virt-compile-warnings.m4 (-Wenum-compare): Omit explicit check.

Christophe Fergeau defa8b8589 events: Fix domain event race on client disconnect
GNOME Boxes sometimes stops getting domain events from libvirtd, even
after restarting it. Further investigation in libvirtd shows that
events are properly queued with virDomainEventStateQueue, but the
timer virDomainEventTimer which flushes the events and sends them to
the clients never gets called. Looking at the event queue in gdb
shows that it's non-empty and that its size increases with each new
events.

virDomainEventTimer is set up in virDomainEventStateRegister[ID]
when going from 0 client connecte to 1 client connected, but is
initially disabled. The timer is removed in
virDomainEventStateRegister[ID] when the last client is disconnected
(going from 1 client connected to 0).

This timer (which handles sending the events to the clients) is
enabled in virDomainEventStateQueue when queueing an event on an
empty queue (queue containing 0 events). It's disabled in
virDomainEventStateFlush after flushing the queue (ie removing all
the elements from it). This way, no extra work is done when the queue
is empty, and when the next event comes up, the timer will get
reenabled because the queue will go from 0 event to 1 event, which
triggers enabling the timer.

However, with this Boxes bug, we have a client connected (Boxes), a
non-empty queue (there are events waiting to be sent), but a disabled
timer, so something went wrong.

When Boxes connects (it's the only client connecting to the libvirtd
instance I used for debugging), the event timer is not set as expected
(state->timer == -1 when virDomainEventStateRegisterID is called),
but at the same time the event queue is not empty. In other words,
we had no clients connected, but pending events. This also explains
why the timer never gets enabled as this is only done when an event
is queued on an empty queue.

I think this can happen if an event gets queued using
virDomainEventStateQueue and the client disconnection happens before
the event timer virDomainEventTimer gets a chance to run and flush
the event. In this situation, virDomainEventStateDeregister[ID] will
get called with a non-empty event queue, the timer will be destroyed
if this was the only client connected. Then, when other clients connect
at a later time, they will never get notified about domain events as
the event timer will never get enabled because the timer is only
enabled if the event queue is empty when virDomainEventStateRegister[ID]
gets called, which will is no longer the case.

To avoid this issue, this commit makes sure to remove all events from
the event queue when the last client in unregistered. As there is
no longer anyone interested in receiving these events, these events
are stale so there is no need to keep them around. A client connecting
later will have no interest in getting events that happened before it
got connected.

Daniel P. Berrange bd172f1345 Fix location of SELinux mount during RPM builds
When building RPMs the host kernel cannot be assumed to match
the target OS kernel. Thus auto-detecting /selinux vs
/sys/fs/selinux based on the host kernel can result in the
wrong choice (eg F18 builds on a RHEL6 host kernel)

Daniel P. Berrange 8d78fd04be Add helper library for testing the qemu monitor code
To be able to test the QEMU monitor code, we need to have a fake
QEMU monitor server. This introduces a simple (dumb) framework
that can do this. The test case registers a series of items to
be sent back as replies to commands that will be executed. A
thread runs the event loop looking for incoming replies and
sending back this pre-registered data. This allows testing all
QEMU monitor code that deals with parsing responses and errors
from QEMU, without needing QEMU around

Peter Krempa 51907779ee virsh: Update only changed scheduler tunables
When setting the cpu tunables in virsh you are able to update only a
subset of them. Virsh while doing the update updated all of the
tunables, changed ones with new values and unchanged with old ones.
This is unfortunate as it:
a) might overwrite some other change by a race condition (unprobable)
b) fails with range checking as some of the old values saved might be
   out of range

This patch changes the update procedure so that only the changed value
is updated on the host.

This patch also fixes a very unprobable memory leak if the daemon would
return a string tunable parameter, as the typed parameter array was not
cleared.

Peter Krempa 972e914f59 qemu: Add range checking for scheduler tunables when changed by API
The quota and period tunables for cpu scheduler accept only a certain

This patch adds a separate range check, that improves error messages
when changing live config and adds the check for persistent config.
This check is done only when using the API. It is still possible to
specify invalid values in the XML.

Laine Stump 98e732fc34 network: prevent infinite hang if ovs-vswitchd isn't running
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=852984

If a network or interface is configured to use Open vSwitch, but
ovs-vswitchd (the Open vSwitch database service) isn't running, the
ovs-vsctl add-port/del-port commands will hang indefinitely rather
than returning an error. There is a --nowait option, but that appears
to have no effect on add-port and del-port commands, so instead we add
a --timeout=5 to the commands - they will retry for up to 5 seconds,
then fail if there is no response.

Laine Stump 89810fc423 build: require netcf-0.2.2 when installing on Fedora18+
A previous patch forced libnl-3 and netcf-0.2.2 (which itself requires
libnl-3) when *building* for Fedora 18+ (and RHEL 7+), but the
install-time Requires: for netcf has always been implicit due to
libvirtd linking with libnetcf.so. However, the since the API of netcf
didn't change when it was rebuilt to use libnl-3, the internal library
version didn't change either, making it possible (from rpm's point of
view) to upgrade libvirt without upgrading netcf (in reality, that
leads to a segfault - see
https://bugzilla.redhat.com/show_bug.cgi?id=853381).

The solution is to put an explicit Requires: line in libvirt's
specfile for fedora >= 18 and rhel >= 7.

Eric Blake c579d6b3d6 build: avoid warnings from gcc 4.2.1
OpenBSD ships with gcc 4.2.1, which annoyingly treats all format
strings as though they were also attribute((nonnull)).  The two
concepts are orthogonal, though, as evidenced by the number of
spurious warnings it generates on uses where we know that
virReportError specifically handles NULL instead of a format
string; worse, since we now force -Werror on git builds, it
prevents development builds on OpenBSD.

I hate to do this, as it disables ALL format checking on older
gcc, and therefore misses out on some useful checks (code that
happened to compile on Linux may still have type mismatches
when compiled on other platforms, as evidenced by the number
of times I have fixed formatting mismatches for uid_t as found
by warnings on Cygwin), but I don't see any other way to keep
-Werror alive and still compile on OpenBSD.

A more invasive change would be to make virReportError() mark
its format attribute as nonnull, and fix (a lot of) fallout;
we may end up doing that anyways as part of danpb's error
refactoring improvements, but not today.

* src/internal.h (ATTRIBUTE_FMT_PRINTF): Use preferred spellings.
* m4/virt-compile-warnings.m4 (-Wformat): Disable on older gcc.

pin. Since it's enough to pass the correct VCPU ID to the function,
the fix is trivial.
