ext/admin: workaround for extension's __init__() called multiple times
tests: teardown fixes
travis: include core-qrexec in tests
api/admin: (ext/admin) limit listing VMs based on qrexec policy
api/internal: extract get_system_info() function
... during tests.
qubes.ext.Extension class is a weird thing that tries to make each extension
a singleton. But this unfortunately have a side effect that __init__()
is called separately for each "instance" (created in Qubes()'s
__init__()), even though this is really the same object. During normal
execution this isn't an issue, because there is just one Qubes() object
instance. But during tests, multiple objects are created.
In this particular case, it caused PolicyCache() to be created twice and
the second one overriden the first one - without properly cleaning it
up. This leaks a file descriptor (inotify one). The fact that cleanup()
was called twice too didn't helped, because it was really called on
the same object, the one requiring cleanup was already gone.
Workaround this by checking if policy_cache field is initialize and
avoid re-initialize it. Also, on Qubes() object cleanup remove that
field, so it can be properly initialized on the next test iteration.
Add few missing app.close() calls on test teardown.
Fix socket cleanup in TC_00_QubesDaemonProtocol() - not only close the
FD, but also unregister it from asyncio event loop.
Various Admin API calls, when directed at dom0, retrieve global system
view instead of a specific VM. This applies to admin.vm.List (called at
dom0 retrieve full VM list) and admin.Events (called at dom0 listen for
events of all the VMs). This makes it tricky to configure a management
VM with access to limited set of VMs only, because many tools require
ability to list VMs, and that would return full list.
Fix this issue by adding a filter to admin.vm.List and admin.Events
calls (using event handlers in AdminExtension) that filters the output
using qrexec policy. This version evaluates policy for each VM or event
(but loads only once). If the performance will be an issue, it can be
optimized later.

gui: fixes from Marek's comments
gui: improvements of feature keyboard layout checks
tests: adapt tests for keyboard-layout
gui: drop legacy qubes-keyboard support
and not mark it as expected failure anymore. Note the removal of the
expected failure isn't just about the changes here, but also about the
actual fix on the qrexec side (ffafd01 "Fix not closed file descriptors in
qubes-rpc-multiplexer" commit in core-qrexec repository).
QubesVM.run_for_stdio() by default captures stderr. In case of call fail
(non-zero return code), captured stderr is included in the exception
object, but isn't printed by default CalledProcessError message.
Make it visible by:
- handling CalledProcessError and including in the test failure message
(when exception is captured already)
- not capturing stderr (if no exception handling is present in the
test)
The main use case for this function is to create qrexec services in VMs.
Since qrexec now require service scripts to be executable, make
create_remote_file() adjust permissions.
If any test-* VMs remains from previous test run, there are removed
before test. self.app doesn't exist at this point, so don't require it
in self.remove_vms().
This commit adds a test case for the QubesVM class's is_fully_usable
method. The verified scenarios are as follows:
* The VM has qrexec enabled, and the qrexec service has been
successfully started.
(The VM becomes "fully usable" in this case.)
* The VM has qrexec enabled, and the qrexec service has failed to start
(Error handling case; the VM is *not* fully usable.)
* The VM does *not* have qrexec enabled.
(The VM becomes "fully usable" in this case.)
Prior to this commit, a properly configured Linux HVM would not
transition from the 'Transient' state to the 'Running' state according
to qvm-ls output, even if the HVM in question had the 'qrexec' feature
disabled.
This issue is caused by an unconditional qrexec check in the
'on_domain_is_fully_usable' method, and is resolved by adding
a check that short-circuits the qrexec check if the aforementioned
feature is not enabled for the VM in question.
