This patch resolves:

  https://bugzilla.redhat.com/show_bug.cgi?id=1035336

The basic problem is that during a network update, the required
iptables rules sometimes change, and this was being handled by simply
removing and re-adding the rules. However, the removal of the old
rules was done based on the *new* state of the network, which would
mean that some of the rules would not match those currently in the
system, so the old rules wouldn't be removed.

This patch removes the old rules prior to updating the network
definition then adds the new rules as soon as the definition is
updated. Note that this could lead to a stray packet or two during the
interim, but that was already a problem before (the period of limbo is
now just slightly longer).

While moving the location for the rules, I added a few more sections
that should result in the iptables rules being redone:

DHCP_RANGE and DHCP_HOST - these are needed because adding/removing a dhcp
host entry could lead to the dhcp service being started/stopped, which
would require that the mangle rule that fixes up dhcp response
checksums sould need to be added/removed, and this wasn't being done.

The code for extracting sub-mounts would just do a STRPREFIX
check on the mount. This was flawed because if there were
the following mounts

 /etc/aliases
 /etc/aliases.db

and '/etc/aliases' was asked for, it would return both even
though the latter isn't a sub-mount.

'make distcheck' has been broken since commit 21685c95; basically,
it emulates the case of a read-only $(srcdir) (such as building
from a tarball exploded onto a CD-ROM), but we were creating our
fake pci device as a symlink into $(srcdir) and failing when that
requires opening the config file for writing:

While trying to debug a failure of virpcitest during 'make distcheck',
I noticed that with a VPATH build, 'cd tests; ./virpcitest' fails for
an entirely different reason.  To reproduce the distcheck failure, I
had to run 'cd tests; abs_srcdir=/path/to/src ./virpcitest'.  But we
document in HACKING that all of our tests are supposed to be runnable
without requiring extra environment variables.

The solution: hardcode the location of srcdir into the just-built
binaries, rather than requiring make to prepopulate environment
variables.  With this, './virpcitest' passes even in a VPATH build
(provided that $(srcdir) is writable; a followup patch will fix the
conditions required by 'make distcheck').  [Note: the makefile must
still pass on directory variables to the test environment of shell
scripts, since those aren't compiled.  So while this solves the case
of a compiled test, it still requires environment variables to pass
a VPATH build of any shell script test case that relies on srcdir.]

tests.

Export string conversion from and to the virStorageVolType enum.

When attempting to backport gluster pools to an older versoin
where there is no VIR_STRDUP, I got a crash from calling
strdup(,NULL). Rather than relying on the current else branch
safely doing nothing when there is no fd, it is easier to just
skip it. While at it, there's no need to explicitly set
perms.label to NULL after a VIR_FREE().

The virsh command 'domxml-to-native' (virConnectDomainXMLToNative())
converts all network devices to "type='ethernet'" in order to make it
more likely that the generated command could be run directly from a
shell (other libvirt network device types end up referencing file
descriptors for tap devices assumed to have been created by libvirt,
which can't be done in this case).

During this conversion, all of the netdev parameters are cleared out,
then specific items are filled in after changing the type. The MAC
address was not one of these preserved items, and the result was that
mac addresses in the generated commandlines were always
00:00:00:00:00:00.

This patch saves the mac address before the conversion, then
repopulates it afterwards, so the proper mac addresses show up in the
commandline.

Commit 348b4e25 introduced a potential problem (thankfully not
in any release): we are attempting to use virFileReadHeaderFD()
on a file that was opened with O_NONBLOCK.  While this
shouldn't be a problem in practice (because O_NONBLOCK
typically doesn't affect regular or block files, and fifos and
sockets cannot be storage volumes), it's better to play it safe
to avoid races from opening an unexpected file type while also
avoiding problems with having to handle EAGAIN while read()ing.

Since the label is at the beginning of the loop, this has the same effect.

With some authentication mechanism (PLAIN for example), sasl_client_start()
can return SASL_OK, which translates to virNetSASLSessionClientStart()
returning VIR_NET_SASL_COMPLETE.
cyrus-sasl documentation is a bit vague as to what to do in such situation,
but upstream clarified this a bit in
http://asg.andrew.cmu.edu/archive/message.php?mailbox=archive.cyrus-sasl&msg=10104

When we got VIR_NET_SASL_COMPLETE after virNetSASLSessionClientStart() and
if the remote also tells us that authentication is complete, then we should
end the authentication procedure rather than forcing a call to
virNetSASLSessionClientStep(). Without this patch, when trying to use SASL
PLAIN, I get:
error :authentication failed : Failed to step SASL negotiation: -1
(SASL(-1): generic failure: Unable to find a callback: 32775)

This patch is based on a spice-gtk patch by Dietmar Maurer.

virNetSASLSessionClientStep logs the data that is going to be passed to
sasl_client_step as input data. However, it tries to log it as a string,
while there is no guarantee that this data is going to be nul-terminated.
This leads to this valgrind log:

The array of sasl_callback_t callbacks which is passed to sasl_client_new()
must be kept alive as long as the created sasl_conn_t object is alive as
cyrus-sasl uses this structure internally for things like logging, so

been called.

Putting together pieces from previous patches, it is now possible
for 'virsh vol-dumpxml --pool gluster volname' to report metadata
about a qcow2 file stored on gluster.  The backing file is still
treated as raw; to fix that, more patches are needed to make the
storage backing chain analysis recursive rather than halting at
a network protocol name, but that work will not need any further
calls into libgfapi so much as just reusing this code, and that
should be the only code outside of the storage driver that needs
any help from libgfapi.  Any additional use of libgfapi within
libvirt should only be needed for implementing storage pool APIs
such as volume creation or resizing, where backing chain analysis
should be unaffected.

In the 'directory' and 'netfs' storage pools, a user can see
both 'file' and 'dir' storage volume types, to know when they
can descend into a subdirectory.  But in a network-based storage
pool, such as the upcoming 'gluster' pool, we use 'network'
instead of 'file', and did not have any counterpart for a
directory until this patch.  Adding a new volume type
'network-dir' is better than reusing 'dir', because it makes
it clear that the only way to access 'network' volumes within
that container is through the network mounting (leaving 'dir'
for something accessible in the local file system).

Actually put gfapi to use, by allowing the creation of a gluster
pool.  Right now, all volumes are treated as raw and directories
are skipped; further patches will allow peering into files to
allow for qcow2 files and backing chains, and reporting proper
volume allocation.  This implementation was tested against Fedora
19's glusterfs 3.4.1; it might be made simpler by requiring a
higher minimum, and/or require more hacks to work with a lower
minimum.

Add support for a new <pool type='gluster'>, similar to
RBD and Sheepdog.  Terminology wise, a gluster volume
forms a libvirt storage pool, within the gluster volume,
individual files are treated as libvirt storage volumes.

* docs/schemas/storagepool.rng (poolgluster): New pool type.
* docs/formatstorage.html.in: Document gluster.
* docs/storage.html.in: Likewise, and contrast it with netfs.

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].

I got annoyed at having to use both 'virsh vol-list $pool --details'
AND 'virsh vol-dumpxml $vol $pool' to learn if I had populated
the volume correctly.  Since two-thirds of the data present in
virStorageVolGetInfo() already appears in virStorageVolGetXMLDesc(),
this just adds the remaining piece of information, as:

<volume type='...'>
  ...
</volume>

* docs/formatstorage.html.in: Document new <volume type=...>.
* docs/schemas/storagevol.rng (vol): Add it to RelaxNG.
* src/conf/storage_conf.h (virStorageVolTypeToString): Declare.
* src/conf/storage_conf.c (virStorageVolTargetDefFormat): Output
the metatype.
(virStorageVolDefParseXML): Parse it, for unit tests.

The bus type IDE being enum Zero, the bus type on pseries system appears as IDE for all the -hda/-cdrom and for disk drives with if="none" type. Pseries platform needs this to appear as SCSI instead of IDE. The ide being not supported, the explicit requests for ide devices will return an error.

The RNG grammar did not allow arbitrary interleaving, which makes
it harder than necessary to create a new volume from handwritten XML.
