[libvirt] [PATCHv2 0/2] Support setting the 'removable' flag for USB disks
by Fred A. Kemp
From: "Fred A. Kemp" <anonym(a)riseup.net>
The commit message of patch #2 explains the purpose of this patch set.
A review would be greatly appreciated!
Note that I've only added the new capability for usb-storage.removable
to the qemu help tests of qemu(-kvm) version 1.2.0, since that's what I
had easily available to get the output of `-device usb-storage,?` from.
I hope that's not an issue, otherwise, is there a way to obtain these
outputs without having to hunt down and install all supported versions?

[libvirt] [PATCH 1/3] CPU: Implement guestData for PPC CPU driver
by Li Zhang
From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com>
On Power platform, Power7+ can support Power7 guest.
It needs to define XML configuration to specify guest's CPU model.
For exmaple:
<cpu match='exact'>
<model>POWER7+_v2.1</model>
<vendor>IBM</vendor>
</cpu>

[libvirt] [PATCH] qemu_hotplug: Resolve DEADCODE coverity error
by John Ferlan
Remove unused 'cgroup' variable in qemuDomainAttachDeviceDiskLive() to
resolve coverity DEADCODE complaint
---
Refactoring of qemuDomainAttachDeviceDiskLive() in the following patch:
https://www.redhat.com/archives/libvir-list/2013-August/msg00079.html
seemed to wake up Coverity and it complained about deadcode as a result
of 'cgroup' only ever been NULL thus the check for it to be non-NULL in
order to call qemuTeardownDiskCgroup() would not be able to occur. The
code actually hadn't changed, but for some reason coverity now found it.
Followed example in qemuDomainChangeDiskMediaLive() and just removed the
'cgroup' variable.

[libvirt] [PATCH] random: don't mix RAND_MAX with random_r
by Eric Blake
FreeBSD 10 recently changed their definition of RAND_MAX, to try
and cover the fact that their evenly distributed results really are
a smaller range than a full power of 2. As a result, I did some
investigation, and learned:
1. POSIX requires random() to be evenly distributed across exactly
31 bits. glibc also guarantees this for rand(), but the two are
unrelated, and POSIX only associates RAND_MAX with rand().
Avoiding RAND_MAX altogether thus avoids a build failure on
FreeBSD 10.
2. Concatenating random bits from a PRNG will NOT provide uniform
coverage over the larger value UNLESS the period of the original
PRNG is at least as large as the number of bits being concatenated.
Simple example: suppose that RAND_MAX were 1 with a period of 2**1
(which means that the PRNG merely alternates between 0 and 1).
Concatenating two successive rand() calls would then invariably
result in 01 or 10, which is a rather non-uniform distribution
(00 and 11 are impossible) and an even worse period (2**0, since
our second attempt will get the same number as our first attempt).
But a RAND_MAX of 1 with a period of 2**2 (alternating between
0, 1, 1, 0) provides sane coverage of all four values, if properly
tempered. (Back-to-back calls would still only see half the values
if we don't do some tempering). We therefore want to guarantee a
period of at least 2**64, preferably larger (as a tempering factor);
POSIX only makes this guarantee for random() with 256 bytes of info.
* src/util/virrandom.c (virRandomBits): Use constants that are
accurate for the PRNG we are using, not an unrelated PRNG.
(randomState): Ensure the period of our PRNG exceeds our usage.
Signed-off-by: Eric Blake <eblake(a)redhat.com>

I debated pushing this under the build-breaker rule, but would
like to get feedback from an actual FreeBSD build first if possible.

[libvirt] [PATCH] build: shipped files must not depend on BUILT_SOURCES
by Eric Blake
'make distcheck' was failing with:
make[3]: Entering directory `/home/eblake/libvirt-tmp2/libvirt-1.1.1/_build/docs'
perl ../../docs/genaclperms.pl ../../src/access/viraccessperm.h > ../../docs/aclperms.htmlinc
/bin/sh: ../../docs/aclperms.htmlinc: Permission denied
when simulating the case of a user doing a VPATH build from a
read-only source tree. The culprit? BUILT_SOURCES are _always_
built, and so must NOT be built into srcdir and need not be part
of the tarball. On the other hand, shipped files must never
depend on files in the builddir. While it would be possible to
fix the problem by generating aclperms.htmlinc into builddir,
we then have the problem that we ship acl.html - we'd have to
rejigger a lot of things to not ship pre-built html. So this
patch goes the other direction - we don't need BUILT_SOURCES,
but instead ensure that we have proper dependencies so that
all files in srcdir are up-to-date at the time the tarball is
created. And because we ship html files in the tarball, that
implies we don't expect users to be able to rebuild them, so
we must not clean any files that would trigger a rebuild except
under the maintainer rules.
* docs/Makefile.am (BUILT_SOURCES): Delete.
(CLEANFILES): Downgrade aclperms.htmlinc cleanup...
(maintainer-clean-local): ...and move hvsupport.html.in...
(MAINTAINERCLEANFILES): ...to a maintainer action.
(hvsupport.html.in): Write into srcdir.

[libvirt] [PATCH] build: fix 'make distcheck' out of the box
by Eric Blake
With the 1.1.1 tarball, if a user does 'make && make distcheck',
things pass, but if they do 'make distcheck' after 'make clean',
there is an odd failure:
GEN ../../docs/devhelp/index.html
I/O error : Permission denied
I/O error : Permission denied
runtime error: file ../../docs/devhelp/devhelp.xsl line 43 element document
xsltDocumentElem: unable to save to ../../docs/devhelp/libvirt-virterror.html
I/O error : Permission denied
I/O error : Permission denied
This implies that the rules for 'make dist' are missing a
dependency - the generated documentation needs to be up-to-date
before creating the tarball, or else the tarball will be missing
files, where the end user will end up trying to rebuild files in
srcdir, and that fails when srcdir is read-only.
1.1.1 plus this patch now works without issues (other issues have
crept in to 1.1.2-rc1 that prevent 'make distcheck' from working,
but those will be cleaned up in later patches).

All that explanation, and just one line to change. :)
Pushing under the build-breaker rule.

[libvirt] [PATCH] cgroup: Don't fail to start a VM when DBus isn't compiled in or running
by Peter Krempa
The systemd code to create cgroups has fallback means built in, but
fails to engage them if a host isn't running DBus or libvirtd is
compiled without DBus (yes, you still don't need to run DBus).
This patch changes the return value in case DBus isn't available to so
that the fallback code can be activated and cgroups are created
manually.
