To prevent the error messages in cfg.mk from triggering the very
same rules they're supposed to explain, we split the message in
the middle of a symbol name, ending up with stuff like
'I am a me'ssage
Instead of relying on these quotation tricks, simply exclude
cfg.mk from the relevant checks.
Being consistent is nice, especially when it comes to defining our
regular expression, where using single quotes instead of double
quotes allows us to leave out a few backslashes.
Changing this required altering a few error messages.
The only remaining use of double quotes is one where they are
actually required for the check to work.
While we have a wiki page describing the feature [1] since the
feature is distributed in our .tar.gz we ought to document it. So
I went ahead, copied the wiki page and reformatted so it fits our
docs coding style.

After 9c17d665fd the tap device for ethernet network type is
automatically precreated before spawning qemu. Problem is, the
qemuxml2argvtest wasn't updated and thus is failing. Because of
all the APIs that new code is calling, I had to mock a lot. Also,
since the tap FDs are labeled separately from the rest of the
devices/files I had to enable NOP security driver for the test
too.

As mock libraries are not to be linked against libvirt, the
sc_prohibit_close syntax-check rule does not apply.
This fixes a syntax-check failure introduced by commit a03cbfe0fb.
There might be cases, like with typed params, where triggering this check isn't
desirable. But including the whole module in the exception regex is not always
to right way of doing things. By adding an option to manually disable this check
on a specific occurrence, the module itself will still be checked against the
rule.
As it turned out, we need to share some enums and declarations between
libvirt.h and libvirt-admin.h, but since our policy forbids direct includes of
libvirt*.h, there has to be some header exempt from this rule. This patch moves
the relevant part of code from libvirt.h.in to libvirt-common.h.in. Moreover,
since there is no need to have libvirt.h generated anymore, introduce a new
header libvirt.h which was previosly ignored from git and make the common
header ignored and generated instead.
Currently the QEMU stdout/stderr streams are written directly to
a regular file (eg /var/log/libvirt/qemu/$GUEST.log). While those
can be rotated by logrotate (using copytruncate option) this is
not very efficient. It also leaves open a window of opportunity
for a compromised/broken QEMU to DOS the host filesystem by
writing lots of text to stdout/stderr.
This makes it possible to connect the stdout/stderr file handles
to a pipe that is provided by virtlogd. The virtlogd daemon will
read from this pipe and write data to the log file, performing
file rotation whenever a pre-determined size limit is reached.

Copy the virtlockd codebase across to form the initial virlogd
code. Simple search & replace of s/lock/log/ and gut the remote
protocol & dispatcher. This gives us a daemon that starts up
and listens for connections, but does nothing with them.

tests: handle backspace-newline pairs in test input files
all the test argv files were line wrapped so that the args
were less than 80 characters.
The way the line wrapping was done turns out to be quite
undesirable, because it often leaves multiple parameters
on the same line. If we later need to add or remove
individual parameters, then it leaves us having to redo
line wrapping.
This commit changes the line wrapping so that every
single "-param value" is one its own new line. If the
"value" is still too long, then we break on ',' or ':'
or ' ' as needed.
This means that when we come to add / remove parameters
from the test files line, the patch diffs will only
ever show a single line added/removed which will greatly
simplify review work.

In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.
Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.
Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.
For this to pe properly separated from other protocols used by the
server, there is second server added which allows access to the whole
virNetDaemon to its clients.

Initial scratch of the admin library. It has its own virAdmConnectPtr
that inherits from virAbstractConnectPtr and thus trivially supports
error reporting.
There's pkg-config file added and spec-file adjusted as well.
Since the library should be "minimalistic" and not depend on any other
library, the list of files is especially crafted for it. Most of them
could've been put to it's own sub-libraries that would be LIBADD'd to
libvirt_util, libvirt_net_rpc and libvirt_setuid_rpc_client to minimize
the number of object files being built, but that's a refactoring that
isn't the orginal aim of this commit.

In order not to bring in any link dependencies, bridge driver doesn't
use the usual stubs as other conditionally-built code does. However,
having the function as a macro imposes a problem with possibly unused
variables if just defined as "0". This was worked around by using
(dom=dom, iface=iface, 0) which should act like a 0 if used in a
condition. However, gcc still bugs about that, so I came up with
another way how to fix that.
Using static inline functions in the header won't collide with anything,
it fixes the bug and does one thing that the macro didn't do. It checks
whenther passed variables are pointers of compatible type. It has only
one downside, and that is that we need to either a) define it with
ATTRIBUTE_UNUSED, which needs an exception in cfg.mk or b) do something
like ignore_value(variable); in the function body. I went with the
first variant.

Some code paths have special logic depending on the page size
reported by sysconf, which in turn affects the test results.
We must mock this so tests always have a consistent page size.
Per-cpu stats are only shown for present CPUs in the cgroups,
but we were only parsing the largest CPU number from
/sys/devices/system/cpu/present and looking for stats even for
non-present CPUs.
This resulted in:
internal error: cpuacct parse error
Introduce a Xen xl parser
This parser allows for users to convert the new xl disk format and
spice graphics config to libvirt xml format and vice versa. Regarding
the spice graphics config, the code is pretty much straight forward.
For the disk {formating, parsing}, this parser takes care of the new
xl format which include positional parameters and key/value parameters.
In xl format disk config a <diskspec> consists of parameters separated by
commas. If the parameters do not contain an '=' they are automatically
assigned to certain options following the order below
target, format, vdev, access
The above are the only mandatory parameters in the <diskspec> but there
are many more disk config options. These options can be specified as
key=value pairs. This takes care of the rest of the options such as
devtype, backend, backendtype, script, direct-io-safe,
The positional paramters can also be specified in key/value form
for example
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
are interpleted to one config.
In xm format, the above diskspec would be written as
phy:/dev/vg/guest-volume,hda,w
The disk parser is based on the same parser used successfully by
the Xen project for several years now. Ian Jackson authored the
scanner, which is used by this commit with mimimal changes. Only
the PREFIX option is changed, to produce function and file names
more consistent with libvirt's convention.

With this change, any patch declared in libvirt.spec with Patch[0-9]* is
automatically applied in %prep. Unlike with the standard %patch[0-9]*,
patches are applied with "git am" to avoid some unexpected results.
However, as a result of this, all patches must be in the right format
for "git am" to be able to apply them; they should ideally be generated
from git using "git format-patch".

The cfg.mk rule for checking preprocessor indentation was

extension matching rule. Fix that and the resolve the
incorrect indentation that is identified.

file is not self-contained, so applications will not directly
