* qubesos/pr/38:
Bad spaces
Add -p to mkdir to skip error if dir already exists
Make dir dom0-updates if not exists on UpdateVM
FixesQubesOS/qubes-issues#3620
Those parameters eventually may eventually be passed to a shell script
(at least /usr/lib/qubes/qubes-rpc-multiplexer). While it is possible to
properly escape shell special characters, lets do safer and less fragile
thing: forbid such characters entirely.
In case of target name, qrexec policy keywords are allowed, and after
recent change, those contains '@', so allow this char.
Avoid passing special characters (like '$' or '@') to the service, even
if in environment variable. Use separate variable (and
qubes-rpc-multiplexer argument) to provide type of original target.
There are two:
- specific VM by name ("name")
- special name, like $adminvm, $dispvm etc ("keyword")
Then, use separate variables to provide actual value:
- QREXEC_REQUESTED_TARGET_KEYWORD (if _TYPE == "keyword")
- QREXEC_REQUESTED_TARGET (if _TYPE == "name")
The later one intentionally is the same as in previous implementation,
to preserve compatibility.
GUI updaters and Packagekit are confused by networkless dom0 and often
report that:
- cannot check for updates (because of no network connection)
- no updates are available, even if they are
The latter happen mostly because PackageKit does not load dnf.conf, so
try to use /etc/yum.repos.d (network repositories) instead of
/etc/yum.real.repos.d (local cache, downloaded by qubes-dom0-update).
Currently PackageKit does not support configuring it, the path is
hardcoded.
Until both of above issues get fixed, prefer console updater.
FixesQubesOS/qubes-issues#1378
It's necessary to add the break at the end of "case -1" statement else the compiler will treat it as fall through and GCC 7 will throw an error because of -Werror=implicit-fallthrough=.
PackageKit is used only by GUI updaters, refresh its cache only then.
Since PackageKit daemon do not read dnf.conf, it doesn't know the right
repository location, so try to access network, which results in
timeouts. But at the same time, it invalidate previous cache, which is
what we need.
Do not delay every qubes-dom0-update call by pkcon call.
- only have one button, because "yes/no" makes no sense in this context
- inform use to use "-t pv" for xl console, because otherwise it won't
work for HVM domains.
- use the actual VM name, not "vmname"
Perhaps the UpdateVM template should be temporarily switched to the
backup too. That would make it really failsafe. Currently it requires
manual recovery (by setting template of UpdateVM to the backup).
DM_UDEV_DISABLE_DISK_RULES_FLAG flag sometimes isn't properly
propagated, so just to be sure, add a flag file
/var/lib/qubes/.qubes-exclude-block-devices to exclude that directory.
Fixes 5c84a0b "udev: don't exclude loop devices pointing outside of
/var/lib/qubes"

clock synchronization mechanism rewritten to use systemd-timesync instead of NtpDate; at the moment, requires:
- modifying /etc/qubes-rpc/policy/qubes.GetDate to redirect GetDate to designated clockvm
- enabling clocksync service in clockvm ( qvm-features clockvm-name service/clocksync true )
Works as specified in issue listed below, except for:
- each VM synces with clockvm after boot and every 6h
- clockvm synces time with the Internet using systemd-timesync
- dom0 synces itself with clockvm every 1h (using cron)

There was a second place with exactly the same bug. See
dad208a "qrexec: fix pending requests cleanup code" for details.

qubes-dom0-update script use qvm-run tool, which is in
qubes-core-admin-client package (python3-qubesadmin isn't enough).
Also, this should fix package installation order during install:
template needs to be installed after qubes-core-admin-client (for
qvm-template-postprocess tool). But we can't add this dependency there
directly, as it will not work on Qubes < 4.0.
