56746d8ad6 maint: Correctly detect wether "gluster" cli tool is accessible
The configure definition previously always defined the GLUSTER_CLI macro
and thus the code needing it wasn't compiled out if the tool wasn't
accessible.

05671b95db storage: netfs: Support lookup of glusterfs pool sources
https://bugzilla.redhat.com/show_bug.cgi?id=1072714

Use the "gluster" command line tool to retrieve information about remote
volumes on a gluster server to allow storage pool source lookup.

Unfortunately gluster doesn't provide a management library so that we
could use that directly, instead the RPC calls are hardcoded in the
command line tool.

69ad6b5756 Define ISCSIADM unconditionally
Commit 5e1d5dd moved the functions using isciadm to util/viriscsi.c,
but ISCSIADM was only defined when the iscsi backend was compiled in.

Define it unconditionally to fix the build (and allow testing
of viriscsi.c) even if iscsi backend is disabled.

2c4870d04f Fix missing char dev lock path case in configure
configure check for character devices lock path calls
AC_DEFINE_UNQUOTED for VIR_CHRDEV_LOCK_FILE_PATH even if
$with_chrdev_lock_files = "no".

So the locking code in conf/virchrdev.c:

 #ifdef VIR_CHRDEV_LOCK_FILE_PATH

is compiled in even if it shouldn't, because VIR_CHRDEV_LOCK_FILE_PATH
is defined as "no", so it tries to create lock files with strange
lock path like 'no/LCK..'.

Fix that by calling AC_DEFINE_UNQUOTED only if $with_chrdev_lock_files
is not 'no'.

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.

590029f672 Introduce new OOM testing support
The previous OOM testing support would re-run the entire "main"
method each iteration, failing a different malloc each time.
When a test suite has 'n' allocations, the number of repeats
requires is  (n * (n + 1) ) / 2.  This gets very large, very
quickly.

This new OOM testing support instead integrates at the
virtTestRun level, so each individual test case gets repeated,
instead of the entire test suite. This means the values of
'n' are orders of magnitude smaller.

The simple usage is

   $ VIR_TEST_OOM=1 ./qemuxml2argvtest
   ...
   29) QEMU XML-2-ARGV clock-utc                                         ... OK
       Test OOM for nalloc=36 .................................... OK
   30) QEMU XML-2-ARGV clock-localtime                                   ... OK
       Test OOM for nalloc=36 .................................... OK
   31) QEMU XML-2-ARGV clock-france                                      ... OK
       Test OOM for nalloc=38 ...................................... OK
   ...

the second lines reports how many mallocs have to be failed, and thus
how many repeats of the test will be run.

If it crashes, then running under valgrind will often show the problem

  $ VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When debugging problems it is also helpful to select an individual
test case

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When things get really tricky, it is possible to request that just
specific allocs are failed. eg to fail allocs 5 -> 12, use

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-12 ../run valgrind ./qemuxml2argvtest

In the worse case, you might want to know the stack trace of the
alloc which was failed then VIR_TEST_OOM_TRACE can be set. If it
is set to 1 then it will only print if it thinks a mistake happened.
This is often not reliable, so setting it to 2 will make it print
the stack trace for every alloc that is failed.

  $ VIR_TEST_OOM_TRACE=2 VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-5 ../run valgrind ./qemuxml2argvtest
  30) QEMU XML-2-ARGV clock-localtime                                   ... OK
      Test OOM for nalloc=36 !virAllocN

0144d72963 build: correctly check for SOICGIFVLAN GET_VLAN_VID_CMD command
In order to make a client-only build successful on RHEL4 (yes, you
read that correctly!), commit 3ed2e54 modified src/util/virnetdev.c so
that the functional version of virNetDevGetVLanID() was only compiled
if GET_VLAN_VID_CMD was defined. However, it is *never* defined, but
is only an enum value, so the proper version was no longer compiled
even on platforms that support it. This resulted in the vlan tag not
being properly set for guest traffic on VEPA mode guest macvtap
interfaces that were bound to a vlan interface (that's the only place
that libvirt currently uses virNetDevGetVLanID)

Since there is no way to compile conditionally based on the presence
of an enum value, this patch modifies configure.ac to check for said
enum value with AC_CHECK_DECLS(), which #defines
HAVE_DECL_GET_VLAN_VID_CMD to 1 if it's successful compiling a test
program that uses GET_VLAN_VID_CMD (and still #defines it, but to 0,
if it's not successful).  We can then make the compilation of
virNetDevGetVLanID() conditional on the value of
HAVE_DECL_GET_VLAN_VID_CMD.

On Fedora 20, with wireshark-devel installed, 'make rpm' failed

F20 is already released without wireshark, I chose to add a new

all existing wireshark plugins belong to the wireshark package,
so I got to invent behavior of how the first third-party wireshark

c91d13bd0f build: fix build on mingw with winpthreads
On my Fedora 20 box with mingw cross-compiler, the build failed with:

../../src/rpc/virnetclient.c: In function 'virNetClientSetTLSSession':
../../src/rpc/virnetclient.c:745:14: error: unused variable 'oldmask' [-Werror=unused-variable]
     sigset_t oldmask, blockedsigs;
              ^

I traced it to the fact that mingw64-winpthreads installs a header
that does #define pthread_sigmask(...) 0, which means any argument
only ever passed to pthread_sigmask is reported as unused.  This
patch works around the compilation failure, with behavior no worse
than what mingw already gives us regarding the function being a
no-op.

* src/util/virutil.h (pthread_sigmask): Rewrite to something that

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].

3fde7ad894 build: kill maintainer mode, always rebuild by default
The automake manual recommends against the use of disabling
maintainer mode by default:

https://www.gnu.org/software/automake/manual/automake.html#maintainer_002dmode

because when it is disabled, the user gets no indication if they
touch a file that would normally require a rebuild.  Automake
1.11 changed things so that AM_MAINTAINER_MODE([enable]) will set
the mode to enabled by default; but RHEL 5 still uses automake 1.9,
where AM_MAINTAINER_MODE did not recognize an argument, and
therefore disables maintainer mode by default.  Having the default
be different according to which version of automake built the
project is annoying, and I _have_ been bitten on RHEL 5 rebuilds
where the default disabled mode led to silently incorrect builds.

The automake manual admits that being able to disable maintainer
mode still makes sense for projects that still store generated
files from the autotools in version control; but we have dropped
that for several years now.  As such, it's finally time to just
ditch the whole idea of maintainer mode, and unconditionally
rebuild autotools files if a dependency changes, without offering
a configure option to disable that mode.

* configure.ac (AM_MAINTAINER_MODE): Drop.

bdc55cc7d2 build: fix build --without-remote
I tried to test ./configure --without-lxc --without-remote.
First, the build failed with some odd errors, such as an
inability to build xen, or link failures for virNetTLSInit.
But when you think about it, once there is no remote code,
all of libvirtd is useless, any stateful driver that depends
on libvirtd is also not worth compiling, and any libraries
used only by RPC code are not needed.  So I patched
configure.ac to make for some saner defaults when an
explicit disable is attempted.  Similarly, since we have
migrated virnetdevbridge into generic code, the workaround
for Linux kernel stupidity must not depend on stateful
drivers being in use.

Then there's 'make check' that needs segregation.

Wow - quite a bit of cleanup to make --without-remote useful :)

drivers and other libraries.  Pick up Linux kernel workarounds
even when qemu and lxc are not being compiled.

Also modified file creation to try to use fallocate(2) to pre-allocate
disk space before copying any data to make sure it fails early on if disk
is full and makes sure we can skip zero blocks when copying file contents.

If fallocate isn't available we will zero out the rest of the file after
cloning and only use sparse cloning if client requested a lower allocation
than the input volume's capacity.

922b7fda77 Add support for using 3-arg pkcheck syntax for process (CVE-2013-4311)
With the existing pkcheck (pid, start time) tuple for identifying
the process, there is a race condition, where a process can make
a libvirt RPC call and in another thread exec a setuid application,
causing it to change to effective UID 0. This in turn causes polkit
to do its permission check based on the wrong UID.

To address this, libvirt must get the UID the caller had at time
of connect() (from SO_PEERCRED) and pass a (pid, start time, uid)
triple to the pkcheck program.

This fix requires that libvirt is re-built against a version of
polkit that has the fix for its CVE-2013-4288, so that libvirt
can see 'pkg-config --variable pkcheck_supports_uid polkit-gobject-1'

0e1f012c1d build: hoist system-specific checks before library checks
Commit f92c7e3 fixed a regression for native builds, but introduced
a regression for cross-compilation builds; in particular,
./autobuild.sh on a Fedora system with mingw cross-compiler fails
with:

checking for qemu-kvm... /usr/bin/qemu-kvm
checking for yajl_parse_complete in -lyajl... no
checking for yajl_tree_parse in -lyajl... no
configure: error: You must install the libyajl library & headers to compile libvirt

Since we default $with_qemu to 'yes' rather than 'check', and then
flip that default based on platform-specific checks, those platform
specifics need to come prior to any library checks that depend on
the value of $with_qemu.

* configure.ac: Ensure system defaults are sane before checking
for things that make decisions based on system default.

e62e0094dc build: fix build with latest rawhide kernel headers
Bother those kernel developers.  In the latest rawhide, kernel
and glibc have now been unified so that <netinet/in.h> and
<linux/in6.h> no longer clash; but <linux/if_bridge.h> is still
not self-contained.  Because of the latest header change, the
build is failing with:

checking for linux/param.h... no
configure: error: You must install kernel-headers in order to compile libvirt with QEMU or LXC support

with details:

In file included from conftest.c:561:0:
/usr/include/linux/in6.h:71:18: error: field 'flr_dst' has incomplete type
  struct in6_addr flr_dst;

We need a workaround to avoid our workaround :)

* configure.ac (NETINET_LINUX_WORKAROUND): New test.
* src/util/virnetdevbridge.c (includes): Use it.

cf83adfb7d build: require libnl-3 if netcf uses it
Commits 9298bfb and f6c2951 both tried to make it possible to
select the correct libnl (1 vs. 3) according to what netcf
used, when both libraries are installed.  This works to avoid
libnl-3 when netcf used libnl-1.  But on the converse side, if
only libnl-1 development code is installed, while netcf uses
libnl-3, then configure happily uses libnl-1 anyways, leading
to a test failure:

$ VIR_TEST_DEBUG=1 ./virdrivermoduletest
TEST: virdrivermoduletest
 1) Test driver "network"                                             ... OK
 2) Test driver "storage"                                             ... OK
 3) Test driver "nodedev"                                             ... OK
 4) Test driver "secret"                                              ... OK
 5) Test driver "nwfilter"                                            ... OK
 6) Test driver "interface"
... lt-virdrivermoduletest: route/tc.c:973: rtnl_tc_register: Assertion
`0' failed.
Aborted

It's much nicer to prevent this at configure time, by requiring that
if we know what netcf used, then we want the same libnl version.  As
before, this can be bypassed by someone who knows what they are doing
by setting LIBNL_CFLAGS (perhaps useful to the rare person where the
build box has a different version of netcf than the installation box).

* configure.ac (LIBNL): If we can prove netcf used libnl-3, then
don't let configure succeed with libnl-1.

f92c7e31fc build: fix regression in requiring yajl for new enough qemu
Jonathan Lebon reported an issue to me off-list about his build
failing to use qemu because he failed to install yajl-devel.  But
I recalled specifically tweaking configure.ac to die in that
situation (commits 350583c, ba9c38b).  After a bit more
head-scratching, we found the cause of the regression: commit
654c709 rearranged things so that the qemu version check now
occurs before AC_ARG_WITH has had a chance to set either
$with_qemu or $with_yajl.

Coincidentally, this fix aligns with a documentation patch that
was just posted to the autoconf mailing list :)

ff77742104 build: avoid obsolete AC_HELP_STRING
Autoconf states that AC_HELP_STRING is obsolete, and that new
programs should use AS_HELP_STRING.  We also had instances of
not properly quoting the macro usage, and not relying on autoconf's
word-wrapping abilities to avoid long lines.  I validated that this
commit has no impact to the generated configure file.

* configure.ac (AC_ARG_WITH, AC_ARG_ENABLE): Autoconf recommends
the use of AS_HELP_STRING.  Also, use proper quoting and wrap long
lines.
* m4/virt-apparmor.m4 (LIBVIRT_CHECK_APPARMOR): Likewise.
* m4/virt-selinux.m4 (LIBVIRT_CHECK_SELINUX): Likewise.
