abd2272c02 secret: Alter virSecretGetSecretString
Rather than returning a "char *" indicating perhaps some sized set of
characters that is NUL terminated, alter the function to return 0 or -1
for success/failure and add two parameters to handle returning the
buffer and it's size.

The function no longer encodes the returned secret, rather it returns
the unencoded secret forcing callers to make the necessary adjustments.

Alter the callers to handle the adjusted model.

1d632c3924 secret: util: Refactor virSecretGetSecretString
Call the internal driver callbacks rather than the public APIs to avoid
calling unnecessarily the error dispatching code and don't overwrite
the error messages provided by the APIs. They are good enough to
describe which secret is missing either by UUID or the usage (basically
name).

eb2116fd9a util: alloc: Introduce freeing helpers that clear the memory before freeing
For a few cases where we handle secret information it's good to clear
the buffers containing sensitive data before freeing them.

Introduce VIR_DISPOSE, VIR_DISPOSE_N and VIR_DISPOSE_STRING that allow
simple clearing fo the buffers holding sensitive information on cleanup
paths.

ced1e846a0 capabilities: Advertise cpuselection if -cpu host is usable
When -cpu host is supported by a QEMU binary, a user can use
<cpu mode='host-passthrough'/> in domain XML even when libvirtd failed
to find a matching model for the host CPU. Let's make it obvious by
advertising <cpuselection/> guest capability whenever -cpu host is
supported.

4b3a46ca6a tests: Introduce check-file-access.pl
This script will check output generated by virtestmock against a
white list. All non matching records found are printed out. So
far, the white list is rather sparse at the moment.
This test should be ran only after all other tests finished, and
should cleanup the temporary file before their execution. Because
I'm unable to reflect these requirements in Makefile.am
correctly, I've introduced new target 'check-access' under which
this test is available.

are now identified and appended into a file for later processing.
The location of the file that contains all the records can be

86d1705a8a virmock.h: Introduce VIR_MOCK_CALL_STAT
There is some magic going on when it comes to stat() or lstat().
Basically, stat() can either be a regular function, an inline
function that calls __xstat(_STAT_VER, ...) or a macro that does
the same as the inline func. Don't ask why is that, just read the
documentation in sys/stat.h and make sure you have a bucket next
to you. Anyway, currently there will not be both stat and __xstat
symbols at the same time, as one of them gets overwritten to the
other one during compilation. But this is not true anymore once
we start chaining our mocking libraries. Therefore we need a
wrapper that calls desired function from glibc.

b90c4b5f50 xlconfigtests: use qemu-xen in all test data files
Some of the test configuration files in tests/xlconfigdata
use the old qemu-dm as the emulator. Many of the configuration
features tested (spice, rbd, multi-usb) are not even usable with
the old qemu. Change these files to use the new qemu-xen (also
known as qemu upstream) emulator.

Note: This change fixes xlconfigtest failures when the old
qemu is actually installed on the system. During device post
parse, the libxl driver attempts to invoke the emulator to
determine if it is the old or new qemu so it can properly set
video RAM defaults. With the old qemu installed, the default
video RAM was set differently than the expected value.
Changing all the test data files to use qemu-xen ensures
predictable results wrt default video RAM size.

400e716d7d libxl: don't attempt to probe a non-existent emulator
When probing the <emulator> with '-help' to determine if
it is the old qemu, errors are reported if the emulator
doesn't exist

libvirt:  error : internal error: Child process
(/usr/lib/xen/bin/qemu-dm -help) unexpected exit status 127:
libvirt:  error : cannot execute binary /usr/lib/xen/bin/qemu-dm:
No such file or directory

Avoid the probe if the specified emulator doesn't exist,
squelching the error. There is no behavior change since
libxlDomainGetEmulatorType() would return
LIBXL_DEVICE_MODEL_VERSION_QEMU_XEN if the probe failed
via virCommandRun().

538012c8a3 Fill out default vram in DeviceDefPostParse
Move filling out the default video (v)ram to DeviceDefPostParse.

This means it can be removed from virDomainVideoDefParseXML

VIR_DOMAIN_VIRT_XEN, since the per-driver callback gets called
before the generic one.

3e42867032 Call per-device post-parse callback even on implicit video
Commit 6879be48 moved adding of an implicit video device after XML
parsing. As a result, libxlDomainDeviceDefPostParse() is no longer
called to set the default vram when adding an implicit device.
Commit 6879be48 assumes virDomainVideoDefaultRAM() will set the
default vram, but it returns 0 if the domain virtType is
VIR_DOMAIN_VIRT_XEN. Attempting to start an HVM domain with vram=0
results in

error: unsupported configuration: videoram must be at least 4MB for CIRRUS

The default vram setting for Xen HVM domains depends on the device
model used (qemu-xen vs qemu-traditional), hence setting the
default is deferred to libxlDomainDeviceDefPostParse().

Call the device post-parse callback even for implicit video,
to fill out the default vram even for VIR_DOMAIN_VIRT_XEN.

e711a3918f util: Fix virGetLastErrorMessage to return proper error when 'err' is NULL
Both virGetLastError and virGetLastErrorMessage call virLastErrorObject method
that returns a thread-local error object. However, if a direct call to malloc
or pthread_setspecific (probably also due to malloc, since it sets ENOMEM)
fail, virLastErrorObject returns NULL which, although incorrectly interpreted
by virGetLastError as no error, still requires the caller to check for NULL
pointer. This isn't the case with virGetLastErrorMessage that also treated it
incorrectly as no error, but returned the literal "no error".
This patch tweaks the checks in the virGetLastErrorMessage function, so that
if virLastErrorObject failed, it returned "unknown error" which is equivalent
to the current approach with virGetLastError and if it returned NULL,
"unknown error" was set.
