This allows to use two or more LIBVIRT_CHECK_(LIB|LIB_ALT|PKG) macros

7b3b254063 wireshark: Use ${exec_prefix} instead of ${prefix}
${exec_prefix} and ${prefix} point to the same directory in
most setups, but when that's not the case the former should
be used for architecture-dependent data such as shared objects,
which makes it the best fit for our Wireshark dissector.

While at it, change all uses of $(var) to ${var}: they are
absolutely identicaly as far as make's concerned, but autoconf
itself seems to prefer the latter form so we might as well
follow suit.

anything about $ws_prefix, so we have to handle the two variables
separately.

2bca7cec0b m4: Check for sanlock_write_lockspace
Currently, we are checking for sanlock_add_lockspace_timeout
which is good for now. But in a subsequent patch we are going to
use sanlock_write_lockspace (which sets an initial value for io
timeout for sanlock). Now, there is no reason to check for both
functions in sanlock library as the sanlock_write_lockspace was
introduced in 2.7 release and the one we are currently checking
for in the 2.5 release. Therefore it is safe to assume presence
of sanlock_add_lockspace_timeout when sanlock_write_lockspace
is detected.

Moreover, the macro for conditional compilation is renamed to
HAVE_SANLOCK_IO_TIMEOUT (as it now encapsulates two functions).

5c2bc001a2 virt-wireshark: Properly substract wireshark prefix
So, when building wireshark plugin, we get the plugindir variable
from the wireshark.pc as well as prefix. Then we replace the
prefix in the plugindir with our own prefix where libvirt is
building to:

  plugindir="${prefix}${plugindir#ws_prefix}"

However, as you can see, there's '$' missing in front of the
ws_prefix variable. This results in the mangled plugindir, for
instance like this:

  plugindir='/usr/usr/lib64/wireshark/plugins'

b436a8ae5c gnulib: add getopt module
Unconditionally use gnulib's getopt module. This is needed by the bhyve driver
to provide a reentrant interface for getopt.

Several gnulib headers rely on features.h being included by ctype.h to provide
__GNUC_PREREQ, but on systems without glibc, this is not provided. In these
cases __GNUC_PREREQ gets redefined to 0, which causes build errors from checks
in src/internal.h.
Therefore, define __GNUC_PREREQ as early as possible. config-post.h is probably
the first header that is included, before any other headers.

c0bc172383 systemd: directly notify systemd instead of using sd_notify
The sd_notify method is used to tell systemd when libvirtd
has finished starting up. All it does is send a datagram
containing the string parameter to systemd on a UNIX socket
named in the NOTIFY_SOCKET environment variable. Rather than
pulling in the systemd libraries for this, just code the
notification directly in libvirt as this is a stable ABI
from systemd's POV which explicitly allows independant
implementations:

"$NOTIFY_SOCKET Daemon Notifications" row:

dc3002b46c wireshark: Fix distcheck
Our distcheck is broken. Well, it works but only by pure chance.
When wireshark plugin is enabled, we try to query which path
should the plugin be installed into. Firstly, we try to ask
pkg-config as some releases of wireshark already sets
corresponding variable in their pkg-config files. However, if we
obtained no value from there we try to construct the path on our
own. Based on our observations it usually is:
$libdir/wireshark/plugins/$version/.
Now, the problem is in the way we are deciding whether we have
obtained the plugin directory from pkg-config or not. Simply
said, we are checking wrong variable. The variable we are
checking has never been set, thus in our test is empty and
therefore we will always construct the plugin dir path on our
own, regardless of its presence in the pkg-config file.
To make things worse, after fixing this problem, VPATH build was
broken as it now tried to install plugin into correct directory.
Yes, this is problem, because --prefix was not honoured and
everything but the plugin was installed into given prefix. I've
managed to resolve this issue by replacing plugin dir prefix with
our own. So when doing regular installation (our prefix ==
wireshark prefix), nothing changes. When doing VPATH build &
installation plugin is installed into correctly prefixed dir.

ccf58bd72a configure: Fix check for --with-login-shell on Windows
The check is supposed to stop users from trying to compile
virt-login-shell on Windows by erroring out during the

  * the value of "x$with_win" is compared to "yes" instead
    of "xyes" (note the "x" in the first string)

  * "test" is not being used, so the script will actually
    try to run a command called "x$with_win" instead of
    performing string comparison

859cb18d54 Initial support for NSS plugin skeleton
Name Service Switch is a glibc feature responsible for many
things. Translating domain names into IP addresses and vice versa
is just one of them. However, currently it's the only
functionality that this commit is tickling. Well, in this commit
the plugin skeleton is introduced. Implementation to come in next
patches.
Because of the future testing, where the implementation is to be
linked with a test, this needs to go into static library. Linking
a program with an .so statically is not portable. Therefore a
dummy libnss_libvirt_impl library is being introduced too.

https://bugzilla.redhat.com/show_bug.cgi?id=1251190

So, if domain loses access to storage, sanlock tries to kill it
after some timeout. So far, the default is 80 seconds. But for
some scenarios this might not be enough. We should allow users to
adjust the timeout according to their needs.

7c8250d765 wireshark: Install to generic plugin directory
There has been a report on the list [1] that we are not
installing the wireshark dissector into the correct plugin
directory. And in fact we are not. The problem is, the plugin
directory path is constructed at compile time. However, it's
dependent on the wireshark version, e.g.

  /usr/lib/wireshark/plugins/1.12.6

This is rather unfortunate, because if libvirt RPMs were built
with one version, but installed on a system with newer one, the
plugins are not really loaded. This problem lead fedora packagers
to unify plugin path to:

  /usr/lib/wireshark/plugins/

Cool! But this was enabled just in wireshark-1.12.6-4. Therefore,
we must require at least that version.

And while at it, on some distributions, the wireshark.pc file
already has a variable that defines where plugin dir is. Use that
if possible.

With the latest patch to the vz driver (7d73ca06ce) I was
getting some compilation errors. It turned out, my installation
of the parallels SDK was not as fresh as it could be. Parallels
installed in my system were missing the
PRL_USE_VNET_NAME_FOR_BRIDGE_NAME symbol which simply was not
introduced at the time I was installing the SDK. The symbol was
introduced in 86e62a5d which was then part of the 7.0.22 release.

3502f79198 maint: update to latest gnulib
Time to update to new gnulib before a release.

gcc 5.1 introduced a new -Wformat-signedness, and new gnulib now
turns it on by default.  However, it is still rather lame at the
moment, because it warns for enums, even though there is no way
to control the signeness of an enum which does not use any members
that are negative or larger than INT_MAX, and even though such an
enum would always print the same for both %d and %u:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66249

In file included from ../../src/util/virarch.c:26:0:
../../src/util/virarch.c: In function 'virArchFromHost':
../../src/util/virarch.c:180:15: error: format '%d' expects argument of type 'int', but argument 9 has type 'unsigned int' [-Werror=format=]
     VIR_DEBUG("Mapped %s to %d (%s)",

So this patch turns off the new warning as part of enabling all
other new gcc 5.1 warnings that gnulib now enables.

* m4/virt-compile-warnings.m4: Ignore -Wformat-signedness, for now.

373973206a rpm-build: use pkg-config to detect wireshark presence
Wireshark supports pkg-config since 1.11.3.  Right now we build
wireshark-dissectior tool as default trough rpm build only on
fedora >= 21 and there is new wireshark that supports pkg-config.
If someone wants to build libvirt with wireshark-dissector against old
wireshark, they should specify the location by hand.

This patch is mainly to fix wrong dependency on wireshark binary as it
doesn't make sense to require that binary file to just get version info

68954fb25c virNetServerRun: Notify systemd that we're accepting clients
Systemd does not forget about the cases, where client service needs to
wait for daemon service to initialize and start accepting new clients.
Setting a dependency in client is not enough as systemd doesn't know
when the daemon has initialized itself and started accepting new
clients. However, it offers a mechanism to solve this. The daemon needs
to call a special systemd function by which the daemon tells "I'm ready
to accept new clients". This is exactly what we need with
libvirtd-guests (client) and libvirtd (daemon). So now, with this
change, libvirt-guests.service is invoked not any sooner than
libvirtd.service calls the systemd notify function.

318ea3cb77 storage: initial support for linking with libgfapi
We support gluster volumes in domain XML, so we also ought to
support them as a storage pool.  Besides, a future patch will
want to take advantage of libgfapi to handle the case of a
gluster device holding qcow2 rather than raw storage, and for
that to work, we need a storage backend that can read gluster
storage volume contents.  This sets up the framework.

Note that the new pool is named 'gluster' to match a
<disk type='network'><source protocol='gluster'> image source
already supported in a <domain>; it does NOT match the
<pool type='netfs'><source><target type='glusterfs'>,
since that uses a FUSE mount to a local file name rather than
a network name.

This and subsequent patches have been tested against glusterfs
3.4.1 (available on Fedora 19); there are likely bugs in older
versions that may prevent decent use of gfapi, so this patch
enforces the minimum version tested.  A future patch may lower
the minimum.  On the other hand, I hit at least two bugs in
3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth
raising the minimum: glfs_readdir is nicer to use than
glfs_readdir_r [1], and glfs_fini should only return failure on
an actual failure [2].

fc8c1787d8 Enable full RELRO mode
By passing the flags -z relro -z now to the linker, we can force
it to resolve all library symbols at startup, instead of on-demand.
This allows it to then make the global offset table (GOT) read-only,
which makes some security attacks harder.

1150999ca4 Build all binaries with PIE
PIE (position independent executable) adds security to executables
by composing them entirely of position-independent code (PIC. The
.so libraries already build with -fPIC. This adds -fPIE which is
the equivalent to -fPIC, but for executables. This for allows Exec
Shield to use address space layout randomization to prevent attackers
from knowing where existing executable code is during a security
attack using exploits that rely on knowing the offset of the
executable code in the binary, such as return-to-libc attacks.

907a39e735 Add a test suite for validating SELinux labelling
There are many aspects of the guest XML which result in the
SELinux driver applying file labelling. With the increasing
configuration options it is desirable to test this behaviour.
It is not possible to assume that the test suite has the
ability to set SELinux labels. Most filesystems though will
support extended attributes. Thus for the purpose of testing,
it is possible to extend the existing LD_PRELOAD hack to
override setfilecon() and getfilecon() to simply use the
'user.libvirt.selinux' attribute for the sake of testing.

cd699ed150 Add some autoconf helper macros for checking for libraries
Most checks for libraries take the same format

  * --with-libFOO=yes|no|check|/some/path  argument
  * check for a function NNN in libFOO.so
  * check for a header file DDD/HHH.h
  * Define a WITH_FOO config.h symbol
  * Define a WITH_FOO make conditional
  * Substitute FOO_CFLAGS and FOO_LIBS make variables
  * Print CFLAGS & LIBS summary at the end

Doing all this correctly is rather difficult, typically
done by copy+paste of a previous usage. Further small
improvements people make are not applied to all previous
usages.

Improve this by creating some helper macros to apply
good practice. First, to perform the actual checks:

  LIBVIRT_CHECK_LIB([SELINUX], [selinux],
     [getfilecon], [selinux/selinux.h])

This checks for 'getfilecon' in -lselinux, and the
existence of 'selinux/selinux.h' header file. If successful
it sets SELINUX_CFLAGS and SELINUX_LIBS. The WITH_SELINUX
config.h macro and WITH_SELINUX make conditional are also
defined.

In some cases we need to check two variants of the same
library

  LIBVIRT_CHECK_LIB_ALT([SASL], [sasl2],
                        [sasl_client_init], [sasl/sasl.h],
                        [SASL1], [sasl],
                        [sasl_client_init], [sasl/sasl.h])

This checks for sasl_client_init in libsasl2, and if that
is not found, checks sasl_client_init in libsasl. If the
first check succeeds WITH_SASL is set, while if the second
check succeeds *both* WITH_SASL and WITH_SASL1 are set.

If the library supports pkg-config, then another variant
is available

  LIBVIRT_CHECK_PKG([AVAHI], [avahi-client], [0.6.0])

This checks for avahi-client >= 0.6.0 via pkg-config
and sets WITH_AVAHI if found.

Finally to print a summary of CFLAGS & LIBs found (if any):

  LIBVIRT_RESULT_LIB([SELINUX])

two detected a revert of 2b804cf.

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.

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.

42af2167a4 build: avoid warnings on older gcc
A previous patch (c606671a) pulled in a newer version of
stat-time.h from gnulib, which causes some warnings in older gcc:

  CC     libvirt_driver_storage_la-storage_backend.lo
cc1: warnings being treated as errors
In file included from ../../src/storage/storage_backend.c:59:
../../gnulib/lib/stat-time.h:55: error: no previous prototype for 'get_stat_atime_ns' [-Wmissing-prototypes]

Upstream gnulib argues that these warnings are stupid (and I agree;
see <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54113>), and has
used a modern gcc feature (#pragma GCC diagnostic push) to avoid the
warning.  But we still aim to compile on RHEL 6.3, with gcc 4.4.6
(not to mention even older platforms like RHEL 5), and therefore
the warning trips up our default of development with -Werror.

It took me a while to figure out how to make our set of warnings
smaller on older gcc without losing the benefit of the warnings
when using newer gcc (such as the one on Fedora 17), but this
should do the trick.

* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Avoid

While libvirt intentionally avoids -Wundef (after all, C99
guarantees sane semantics of treating undefined macros as 0),
the glibc insanity of #warning on _FORTIFY_SOURCE coupled with

75da320087 build: fix build at -O2 on rawhide
I had previously tested commit 059d746 with -O intentionally omitted
from my CFLAGS; but that means that I missed out on this warning
from gcc 4.6.2 when optimizations are enabled:

util/buf.c: In function 'virBufferGetIndent':
util/buf.c:86:1: error: function might be candidate for attribute 'pure' [-Werror=suggest-attribute=pure]

While it is probably a good idea to add the attributes and silence
this warning, it's also invasive; 'make -k' found more than 75 such
complaints.  And it doesn't help that gcc 4.6.2 is still buggy
(coreutils reported a case where gcc 4.6.2 incorrectly suggested
marking a function pure that incremented a global variable; fixed
in gcc 4.7).  So the best fix for now is to disable the warning.

It also doesn't help that I stumbled across another problem - gcc
documents that -Wsuggest-attribute=pure only warns if you use -O,
or if you use -fipa-pure-const.  But in practice, when I omitted -O
but added -fipa-pure-const, the warnings are fickle - I got warnings
for simple compilation that disappeared when I also added -fPIC.
And the way libtool compiles things is with -fPIC first, then without
-fPIC but with errors sent to /dev/null - which meant that without
disabling -Wsuggest-attribute=pure, I got a compile error with no
message.  :(  See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10197

Allows bootstrap to work on FreeBSD, where gzip doesn't have a '.'
in its version; and silences false positives in the new
'make syntax-check' rule.

* .gnulib: Update to latest.
* bootstrap: Synchronize to upstream.
* .x-sc_bindtextdomain: New exemptions.
* Makefile.am (syntax_check_exceptions): Ship new file.
* .gitignore: Regenerate per latest bootstrap, anchor entries that
are only in the root directory, and consolidate entries from other
generated .gitignore files.
* build-aux/.gitignore, m4/.gitignore, po/.gitignore: Remove from
version control, since bootstrap generates them.

e7064aa6a2 build: restore operation of bit-rotted 'make cov'
'./autobuild.sh' with lcov installed discovered that our
coverage support has been bit-rotting for a while.  This
restores it back to a successful state, although I have
not yet spent any time looking through the resulting files to
look for low-hanging fruit in the unit test coverage front.

* configure.ac: Clear COMPILER_FLAGS at right place.
* Makefile.am (cov): Newer genhtml no longer likes plain -s.
* m4/compiler-flags.m4 (gl_COMPILER_FLAGS): Don't AC_SUBST
COMPILER_FLAGS; it is a shell variable for use in configure only.
* src/Makefile.am (AM_CFLAGS, AM_LDFLAGS): New variables, to make
it easier to provide global flag additions.  Use throughout, to
uniformly apply coverage flags.
* .gitignore: Globally ignore gcov output.
* daemon/.gitignore: Simplify.
* src/.gitignore: Likewise.
* tests/.gitignore: Likewise.

e07cf19fe5 build: don't use "test cond1 -o cond2": it's not portable
* configure.ac: Use "test cond1 || test cond2" instead.
* m4/compiler-flags.m4 (gl_COMPILER_FLAGS): Likewise.
* tests/test-lib.sh (verbose): Likewise.

48dc345f2d correct and tighten up .*ignore files
* .cvsignore: Don't ignore *.orig or *.rej.  They're not build products.
Don't ignore the entire m4 directory.
* Makefile.maint (sync-vcs-ignore-files): Correct quoting.
Use sed rather than a for loop.
Search only version-controled files (for reproducibility)
* gnulib/lib/netinet/.cvsignore: Append missing newline-at-EOF,
so that the use of sed doesn't mistakenly concatenate lines.
* gnulib/lib/sys/.cvsignore: Likewise.
* m4/.cvsignore: Ignore acinclude.m4 and aclocal.m4, not *.m4.
* .hgignore: Regenerate.
* all .gitignore files: Regenerate.

261e7581b1 Use gnulib, starting with its physmem and getaddrinfo modules.
New files go into these directories:
  gnulib/lib
  gnulib/m4
  gnulib/tests

* bootstrap: A wrapper around gnulib-tool.
* configure.in: Invoke gl_EARLY and gl_INIT, being careful to put gl_EARLY
before any macro that uses AC_COMPILE_IFELSE.
(AC_OUTPUT): Add lib/Makefile and gl-tests/Makefile.  Remove m4/Makefile.
* Makefile.am (SUBDIRS): Add gnulib/lib and remove m4.  Add gnulib/tests
early enough that those tests run before any libvirt unit tests.
* m4/Makefile.am: Remove file.  Not needed.
* src/Makefile.am (INCLUDES): Add -I$(top_srcdir)/gnulib/lib -I../gnulib/lib.
(LDADDS, libvirt_la_LIBADD): Add ../gnulib/lib/libgnu.la.
* src/nodeinfo.c: Include "physmem.h".
* qemud/qemud.c, src/remote_internal.c: Include "getaddrinfo.h".
(MEMINFO_PATH, linuxNodeInfoMemPopulate): Remove definitions.
(virNodeInfoPopulate): Use physmem_total, not linuxNodeInfoMemPopulate.
* tests/Makefile.am (INCLUDES): Add -I$(top_srcdir)/gnulib/lib -I../gnulib/lib.
(LDADDS): Add ../gnulib/lib/libgnu.la.
* qemud/Makefile.am (libvirtd_LDADD): Add ../gnulib/lib/libgnu.la.
* tests/nodeinfotest.c (linuxTestCompareFiles): No longer read total
memory from a file.
Update expected output not to include "Memory: NNNN"
* tests/nodeinfodata/linux-nodeinfo-1.txt:
* tests/nodeinfodata/linux-nodeinfo-2.txt:
* tests/nodeinfodata/linux-nodeinfo-3.txt:
* tests/nodeinfodata/linux-nodeinfo-4.txt:
* tests/nodeinfodata/linux-nodeinfo-5.txt:
* tests/nodeinfodata/linux-nodeinfo-6.txt:
* src/test.c [WITH_TEST]: Remove definition of _GNU_SOURCE that
would conflict with the one now in "config.h".
* autogen.sh: Add -I gnulib/m4.
* src/conf.c, src/sexpr.c: Don't define _GNU_SOURCE.
Instead, include "config.h".
* qemud/qemud.c: Remove definition of _GNU_SOURCE.
* src/openvz_driver.c: Likewise.
* src/qemu_driver.c: Likewise.
* src/remote_internal.c: Likewise.

* configure.in: Use AC_CONFIG_AUX_DIR(build-aux), so that a bunch
of gettextize-generated files go into build-aux/, rather than in
the top-level directory.
* .cvsignore: Adjust.
* build-aux/.cvsignore: New file.
