I ran 'make dist' in the directory left over from ./autobuild.sh
(which was configured for a mingw cross build); the resulting
tarball had more files than 'make dist' on a normal Linux build.
I traced it to the fact that we were distributing a generated
file, but only when configure said the end user had to generate
the file in the first place. In the process, I noticed that
we had some difference in symbol file names; I added a comment
explaining why the difference exists (after first trying to
normalize the names and hitting VPATH build failures).
* configure.ac (LIBVIRT_QEMU_SYMBOL_FILE): Add some comments.
* src/Makefile.am (EXTRA_DIST): No need to ship a generated file;
particularly since which file is built depends on configure results.
Commit dfa1e1dd removed libxenctrl from LIBXL_LIBS, but the libxl
driver uses a symbol from this library. Explicitly link with
libxenctrl instead of relying on the build system to support
implicit DSO linking.
The functionality provided in virchrdev.c (previously virconsole.c) is
applicable to other types of character devices besides consoles, such
as channels. This patch is just code motion, renaming things such as
"console" or "pty", instead using more general terms such as
"character device" or "device path".
A recent build failure made me realize that we could usefully add
a bit more information to configure output, for aid in analysis of
failed builds. Pulling in the autobuild module merely adds these
four lines to configure output:
configure: autobuild project... libvirt
configure: autobuild revision... v1.0.1-113-g7a74eea
configure: autobuild hostname... myhost
configure: autobuild timestamp... 20130102T233543Z
which can be useful even if not using the Autobuild project to parse
build logs.
* bootstrap.conf (gnulib_modules): Add autobuild.
* configure.ac: Favor git version over release version, when available.
Commit 8b8fcdea introduced a check for broken gcc -Wlogical-op,
but did not guard the check against non-gcc compilers, which might
lead to spurious failures when another compiler encounters an
unknown pragma. Additionally, all of our compiler warning logic
should belong in a single file, and use cache variables to allow
overriding the decision at configure time if necessary.
* configure.ac (BROKEN_GCC_WLOGICALOP): Move...
* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): ...here,
and update to modern autoconf idioms.
Some older versions of GCC report a false positive on code like
char * haystack, needle;
strchr(haystack, needle);
Added an extra check in configure.ac which will
#define BROKEN_GCC_WLOGICALOP 1
in this case, allowing to special handle "offending" code.

This adds an implementation of virNetSocketGetUNIXIdentity()
using LOCAL_PEERCRED socket option and xucred struct, defined
in <sys/ucred.h> on systems that have it.
* Autotools changes:
- Don't assume Qemu is Linux-only
- Check Linux headers only on Linux
- Disable firewalld on FreeBSD
* Initctl:
Initctl seem to present only on Linux, so stub it on other platforms
* Raw I/O: Linux-only as well
* Headers cleanup

This patch converts the Xen libxl driver to support only Xen >= 4.2.
Support for Xen 4.1 libxl is dropped since that version of libxl is
designated 'technology preview' only and is incompatible with Xen 4.2
libxl. Additionally, the default toolstack in Xen 4.1 is still xend,
for which libvirt has a stable, functional driver.
It may take some time for sanlock to add a lockspace. And if user
restart libvirtd service meanwhile, the fresh daemon can fail adding
the same lockspace with EINPROGRESS. Recent sanlock has
sanlock_inq_lockspace() function which should block until lockspace
changes state. If we are building against older sanlock we should
retry a few times before claiming an error. This issue can be easily
reproduced:
for i in {1..1000} ; do echo $i; service libvirtd restart; sleep 2; done

When using --without-$name --without-secdriver-$name with $name being
selinux or apparmor, configure will fail saying that AppArmor/SELinux
development package must be installed.
This is caused by a small bug in --with-secdriver-$name handling in
configure.ac which treats --without-secdriver-$name when $name as if the
user had requested to enable $name when $name couldn't be detected on
the system.
This commit also makes sure the detection checks for disabled
secdrivers do not needlessly get run, especially as this could
cause an error as well in --with-$name --without-secdriver-$name
situations.
libvirt started using sanlock_killpath to implement on_lockfailure
action. Since sanlock_killpath was introduced in sanlock 2.4, libvirt
fails to build with older sanlock.
We are currently able to work only with non-translated SELinux
contexts, but we are using functions that work with translated
contexts throughout the code. This patch swaps all SELinux context
translation relative calls with their raw sisters to avoid parsing
problems.
The problems can be experienced with mcstrans for example. The
difference is that if you have translations enabled (yum install
mcstrans; service mcstrans start), fgetfilecon_raw() will get you
something like 'system_u:object_r:virt_image_t:s0', whereas
fgetfilecon() will return 'system_u:object_r:virt_image_t:SystemLow'
that we cannot parse.
I was trying to confirm that the _raw variants were here since the dawn of
time, but the only thing I see now is that it was imported together in
the upstream repo [1] from svn, so before 2008.
Thanks Laurent Bigonville for finding this out.

Add a read-only udev based backend for virInterface. Useful for distros
that do not have netcf support yet. Multiple libvirt based utilities use
a HAL based fallback when virInterface is not available which is less
than ideal. This implements:
* virConnectNumOfInterfaces()
* virConnectListInterfaces()
* virConnectNumOfDefinedInterfaces()
* virConnectListDefinedInterfaces()
* virConnectListAllInterfaces()
* virConnectInterfaceLookupByName()
* virConnectInterfaceLookupByMACString()
curl_global_init is not thread-safe. curl_easy_init might call
curl_global_init when it was no called before. But curl_easy_init
can be called from different threads by the ESX driver. Therefore,
call curl_global_init from virInitialize to stop curl_easy_init from
calling it.

Commit f6430390 broke builds on RHEL 5, where glibc (2.5) is too
old to support mkostemp (2.7) or htole64 (2.9). While gnulib
has mkostemp, it still lacks htole64; and it's not worth dragging
in replacements on systems where journald is unlikely to exist
in the first place, so we just use an extra configure-time check
as our witness of whether to attempt compiling the code.
* src/util/logging.c (virLogParseOutputs): Don't attempt to
compile journald on older glibc.
* configure.ac (AC_CHECK_DECLS): Check for htole64.
