Introduce a helper that only calls closedir if DIR* is non-NULL
and sets it to NULL afterwards.

The only possible error is EBADFD.
Since we only use the directory stream returned by opendir,
this should never happen.

The virUSBDeviceFind* callers do not check errno after calling
this function.

Add utility to format the virSecretLookupTypeDefPtr in XML

Move to virsecret.c and rename to virSecretLookupParseSecret. Also convert
to usage xmlNodePtr and virXMLPropString rather than virXPathString.

Move the enum into a new src/util/virsecret.h, rename it to be
virSecretLookupType. Add a src/util/virsecret.h in order to perform
a couple of simple operations on the secret XML and virSecretLookupTypeDef
for clearing and copying.

This includes quite a bit of collateral damage, but the goal is to remove
the "virStorage*" and replace with the virSecretLookupType so that it's
easier to to add new lookups that aren't necessarily storage pool related.

Introduced by commit d5756794, unused at the time.

Since introduction of the DAC security driver we've documented that
seclabels with a leading + can be used with numerical uid. This would
not work though with the rest of libvirt if the uid was not actually
used in the system as we'd fail when trying to get a list of
supplementary groups for the given uid. Since a uid without entry in
/etc/passwd (or other user database) will not have any supplementary
groups we can treat the failure to obtain them as such.

This patch modifies virGetGroupList to not report the error for missing
users and makes it return an empty list or just the group specified in
@gid.

All callers will grant less permissions to a user in case of failure of
this function and thus this change is safe.

In some cases it will be necessary to ignore errors reported from this
function. This allows suppressing them to avoid spamming logs.

For parsing a bitmap of an unknown size.

Most the callers pass 0 in one form or another, including
vircapstest which used VIR_ARCH_NONE.

This will be used for the caller that needs to specify a separator.
Currently identical to virBitmapParse.

Also change one test case to use the new function.

This is only used by one caller.

Commit b3d06987 added peer address setting to the low level
virNetDevSetIPAddress() function, but ended up causing a segfault in
cases where the caller passed NULL for peer address.

Commit a3510e33 fixed the segfault, but managed to cause us to
skip setting the broadcast address when setting an interface's IP
address. The result is that the broadcast address is 0.0.0.0 for all
libvirt-created bridges (and interfaces in lxc containers with IP
addresses set by libvirt).

This was reported on the mailing list:

  https://www.redhat.com/archives/libvir-list/2016-June/msg00027.html

but I was too busy to investigate at the time. I found it by accident
today while refactoring virNetDevSetIPAddress(). Since this regression
is present in the 1.3.5 release, I'm sending the bugfix as a separate
patch from my larger refactoring patchset.

Commit id '743db933' broke at least one syntax check rule regard open/close
braces and perhaps more with spacing.  Just remove the braces

In the auth config file, it is currently required to have
an entry for each hostname to connect to, eg

  [auth-libvirt-prod1.example.com]
  credentials=prod

This is inconvenient when there are large numbers of machines
all with the same credentials. Add support for a default
entry:

  [auth-default]
  credentials=prod

This function is plenty of ifdefs providing implementations for
Linux, *BSD and OS-X. However, if we are being build for any
other architecture, all that's left behind by preprocessor is
just a error reporting call and return of -1. In that case,
passed arguments are unused:

../../src/util/virhostcpu.c: In function 'virHostCPUGetInfo':
../../src/util/virhostcpu.c:966:33: error: unused parameter 'cpus' [-Werror=unused-parameter]

The virQEMUDriverConfig object contains lists of
loader:nvram pairs to advertise firmwares supported by
by the driver, and qemu_conf.c contains code to populate
the lists, all of which is useful for other drivers too.

To avoid code duplication, introduce a virFirmware object
to encapsulate firmware details and switch the qemu driver
to use it.

In preparation for moving all the memory related APIs out of
the nodeinfo file, give them a virHostMem name prefix.
Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Nearly all the methods in the nodeinfo file are given a
'const char *sysfs_prefix' parameter to override the
default sysfs path (/sys/devices/system). Every single
caller passes in NULL for this, except one use in the
unit tests. Furthermore this parameter is totally
Linux-specific, when the APIs are intended to be cross
platform portable.

This removes the sysfs_prefix parameter and instead gives
a new method linuxNodeInfoSetSysFSSystemPath for use by
the test suite.

For two of the methods this hardcodes use of the constant
SYSFS_SYSTEM_PATH, since the test suite does not need to
override the path for thos methods.

Split out the code for XML validation into a new function.

Split out all the code initializing the validator
to a separate function.

Split out the code cleaning up the validator.

Store all the data related to RNG validation in one structure to
allow splitting virXMLValidateAgainstSchema.

Document the return value of virRandomBytes as 0 or some errno value and
then make sure all callers make the proper checks.

This speeds up node_device_udev driver startup 11x.

Simplify the logic

Move out the code depending on HAVE_DECL_ETHTOOL_GFEATURES.

Split out the features that we probe via various ethtool commands
and ETHTOOL_GFLAGS.

Rename struct elem to virNetDevEthtoolFeatureCmd and move it
out of the function to allow reusing it.
