Using 'int ret = strcmp(a, b)' in a qsort function is a valid use of
str[n]cmp that should _not_ be turned to STREQ, but it was falling
foul of our specific syntax-check.  Meanwhile, gnulib's maint.mk
already has a tighter bound for strcmp, so we can copy that regex and
just check for strncmp, which results in fewer false positives that
require exceptions.

The code in SELinuxRestoreSecurityChardevLabel() was trying to
use SELinuxSetFilecon directly for devices or file types while
it should really use SELinuxRestoreSecurityFileLabel encapsulating
routine, which avoid various problems like resolving symlinks,
making sure he file exists and work around NFS problems

Include locale.h for setlocale().

Revert the usage string back to it's original form.

Use puts() instead of fputs(), as fputs() expects a FILE*.

Add closing parenthesis to some vah_error() calls.

Use argv[0] instead of an undefined argv0.

Last time I ran ./autobuild.sh was on F13; and upgrading to F14
exposed these leftovers due to a newer gcov than what was in the stale
files, in the form of spurious messages that break 'make check':

+profiling:/home/remote/eblake/libvirt-tmp/tools/virsh-console.gcda:Version mismatch - expected 405R got 404R

and concluding with a bug in the autobuild.sh script itself:

Allows bootstrap to work on FreeBSD, where gzip doesn't have a '.'

Per the gettext developer:
http://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00019.html
http://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00021.html

gettext() doesn't work correctly on all platforms unless you have
called setlocale().  Furthermore, gnulib's gettext.h has provisions
for setting up a default locale, which is the preferred method for
libraries to use gettext without having to call textdomain() and
override the main program's default domain (virInitialize already
calls bindtextdomain(), but this is insufficient without the
setlocale() added in this patch; and a redundant bindtextdomain()
in this patch doesn't hurt, but serves as a good example for other
packages that need to bind a second translation domain).

This patch is needed to silence a new gnulib 'make syntax-check'
rule in the next patch.

I am replacing the last instances of close() I found with VIR_CLOSE() / VIR_FORCE_CLOSE respectively.

The first part patches virsh, which I missed out on previously.

The 2nd patch I had left out intentionally to look at it more carefully:
The 'closed' variable could be easily removed since it wasn't used anywhere else. The possible race condition that could result from the filedescriptor being closed and not set to -1 (and possibly let us write into 'something' totally different if the fd was allocated by another thread) seems to be prevented by the qemuMonitorLock() already placed around the code that reads from or writes to the fd. So the change of this code as shown in the patch should not have any side-effects.

Rather than only cleaning any remaining ebtables rules, also clean those applied to iptables and ip6tables when detecting the IP address of an interface. Previous applied iptables rules may hinder DHCP packets.

Similarly to deprecating close(), I am now deprecating fclose() and
introduce VIR_FORCE_FCLOSE() and VIR_FCLOSE(). Also, fdopen() is replaced with
VIR_FDOPEN().

Most of the files are opened in read-only mode, so usage of
VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write
mode already had the fclose()<  0 check and I converted those to
VIR_FCLOSE()<  0.

I did not find occurrences of possible double-closed files on the way.

* daemon/libvirtd.c

* src/qemu/qemu_monitor_text.c (qemuMonitorTextChangeMedia)

Currently only support domain start and shutdown, for domain start,
record timestamp before the qemu command line, and for domain shutdown,
just say it's shutting down with timestamp.

* src/qemu/qemu_driver.c (qemudStartVMDaemon, qemudShutdownVMDaemon
  introduced two macros - START_POSTFIX, SHUTDOWN_POSTFIX)

(ebiptablesWriteToTempFile): Use /bin/sh.
(bash_cmd_path): Delete.

This has been optional in netcf for awhile, but the change hadn't been
propogated to the libvirt copy of the RNG.

In a second step I am converting the netlink send/receive functions to
use libnl.

I tested this with 802.1Qbg profiles and my test server and did not see
a regression.

Caveat: The online documentation of libnl talks about nl_socket_alloc()
but the header file provides nl_handle_alloc() -- this could be a hint
to a possible problem between libnl versions...

http://www.infradead.org/~tgr/libnl/doc/group__socket.html

versus

Eric Blake pointed out a deficiency in this regex when it was
copy-pasted into network.rng. This is just propogating the fix back to
its origin.

This is more flexible regarding the location of the python binary
but doesn't allow to pass the -u flag. The -i flag can be passed
from inside the script using the PYTHONINSPECT env variable.

This fixes a problem with the esx_vi_generator.py on FreeBSD.

This is the case on FreeBSD.

Otherwise GCC complains about malloc being unknown on FreeBSD.

This also fixes configure problems on FreeBSD, as test doesn't
understand '==' there.

tools/console.c depends on daemon/event.h.

Tweak pre tags to achieve proper indentation of their
plaintext representation. Also use more b/i/code tags.
