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)

Instead of calling 'su' to switch the user, use own implementation of
this. Thanks to PAM it's pretty simple. The main reason is to have
control over process waiting for session termination (to call
pam_close_sesion/pam_end). Especially we don't want it to keep std* fds
open, which would prevent qrexec-agent from receiving EOF when one of
them will be closed.
Also, this will preserve QREXEC_AGENT_PID environment variable.

It isn't really needed. It was used to workaround libusb bug (causing
crash when the system does not have any USB controller), but since we
use HVM now which do have some USB controllers it isn't needed anymore.
Also, it is not available in stock Fedora kernels.
Qubes VM require few config options in grub. Ship appropriate
configuration. Debian have grub.d support, so it can be done cleanly.
On Fedora, /etc/default/grub needs to be modified. Still keep the
options in separate file, but include it manually from
/etc/default/grub.

- there are many netcat versions (openbsd, nmap, ...), which behave
differently - especially while handling EOF

good)

While it doesn't make sense to install qubes-core-agent without qrexec,
it may make sense to do the otherway around - install just
qrexec-agent without all the qrexec services and configuration. For
example on some pre-installed system.

When a file is moved to other package, the new package needs Replaces:

This will save a lot of dependencies if networking is not needed in VMs
based on given template. Thanks to updates proxy over qrexec, template

In Fedora it makes little sense, but in Debian it allows to avoid a lot

Configure package manager to use 127.0.0.1:8082 as proxy instead of
"magic" IP intercepted later. The listen on this port and whenever
new connection arrives, spawn qubes.UpdatesProxy service call (to
default target domain - subject to configuration in dom0) and connect
its stdin/out to the local TCP connection. This part use systemd.socket
unit in case of systemd, and ncat --exec otherwise.
On the other end - in target domain - simply pass stdin/out to updates
proxy (tinyproxy) running locally.
It's important to _not_ configure the same VM to both be updates proxy and
use it. In practice such configuration makes little sense - if VM can
access network (which is required to run updates proxy), package manager
can use it directly. Even if this network access is through some
VPN/Tor. If a single VM would be configured as both proxy provider and
proxy user, connection would loop back to itself. Because of this, proxy
connection redirection (to qrexec service) is disabled when the same VM
also run updates proxy.

When /etc/yum.conf is not present (yum-deprecated not installed), don't
try to append to it. It would result in invalid configuration file -
without any section header, and break yum when installed later.
Since 'script' xenstore entry no longer allows passing arguments
(actually this always was a side effect, not intended behaviour), we
need to pass additional parameters some other way. Natural choice for
Qubes-specific script is to use QubesDB.
And since those parameters are passed some other way, it is no longer
necessary to keep it as separate script.

Up until today, Qubes OS would insist on either masking or disabling
or activating units that should get their state properly changed
but only on first package install (when the template is built).
This commit adds the possibility of having two types of unit presets:
* Initial presets: these are only changed state during first package
installs.
* Upgrade presets: these get their state changed during first
package installs as well as during upgrades.
All the maintainer has to do is abide by the instructions in the
preset file. Nothing else is necessary.
Namely, this allows users to enable SSHD on their templates or
standalone VMs and still keep it enabled even after the
qubes-core-vm-systemd package is upgraded.
Matt really wanted that, and so did I, so now we can do it!

Main changes:
- change language from bash to python, introduce qubesagent python package
- support both nftables (preferred) and iptables
- new interface (https://qubes-os.org/doc/vm-interface/)
- IPv6 support
- unit tests included
- nftables version support running along with other firewall loaded

The systemctl in Debian unstable fails when trying to disable a removed
service. The manpage do not mention a switch to change this behaviour.
But it says:
Note that this operation creates only the suggested symlinks for
the units. While this command is the recommended way to manipulate
the unit configuration directory, the administrator is free to make
additional changes manually by placing or removing symlinks in the
directory.
So a simple rm should be fine.
This doesn't help when xen update is installed after this one. So, deal
with it in xen %post itself.

systemctl preset output lengthy warning when trying to operate on
non-existing unit. This preset action is meant to disable unit, so it's
even better it doesn't exists.
This have many advantages:
- prevent XSS (QubesOS/qubes-issues#1462)
- use default browser instead of default HTML viewer
- better qrexec policy control
- easier to control where are opened files vs URLs
For now allow only http(s):// and ftp:// addresses (especially prevent
file://). But this list can be easily extended.

xdg-open is more robust in choosing default application for particular
file type: it supports fallback if the preferred application isn't
working, and most importantly it support system-wide defaults
(/usr/share/applications/defaults.list,
/usr/share/applications/mimeapps.list), so no "random" application is
chosen.
By default xdg-open tries to use environment-specific tool, like
gvfs-open - which isn't good for us, because many such tools do not wait
for editor/viewer termination. That would mean that DisposableVM would
be destroyed just after opening the file.
To avoid such effect, we set DE=generic.
FixesQubesOS/qubes-issues#1621
No functional change.
This will make it easier to switch the tool (without recompiling
vm-file-editor), or even use differrent tools depending on some
conditions.

Explicitly block something like "curl http://10.137.255.254:8082" and

Since this proxy is used only when explicitly configured in application
(package manager), there is no point in worrying about user
_erroneously_ using web browser through this proxy. If the user really
want to access the network from some other application he/she can always
alter firewall rules for that.

Among other things this also fixes build failure - those scripts were

Initial size of those tmpfs-mounted directories is calculated as 50% of
RAM at VM startup time. Which happen to be quite small number, like
150M. Having such small /tmp and/or /dev/shm apparently isn't enough for
some applications like Google chrome. So set the size statically at 1GB,
which would be the case for baremetal system with 2GB of RAM.

Usage of _static_ files (dropins) to override some of autostart entries

qubes-desktop-file-install is called by qubes-triggers-desktop-file-install. It's
arguments are based on the Gnome desktop-install-file utility to allow it to be replaced
by same. Currently the Gnome utility can not be used since it automatically validates
the .desktop entry files with no option to skip validation and will fail on some third
party .desktop files that are not formed properly.
A single trigger script is shared between Fedora, Debian. This script is used by the
package managers triggers and will copy original .desktop files from `/etc/xdg/autostart`
to `/usr/share/qubes/xdg/autostart` and modify the OnlyShownIn / NotShownIn, etc. The
original .desktop files are left untouched and left in place.
Qubes modifies the XDG_CONFIG_DIRS to first include the `/usr/share/qubes/xdg`
directory (XDG_CONFIG_DIRS=/usr/share/qubes/xdg:/etc/xdg).
If a package gets removed, it's desktop entry is also removed from the /usr/share/qubes/xdg
directory.
'qubes-desktop-file-install' options:
--dir DIR Install desktop files to the DIR directory (default: <FILE>)
--force Force overwrite of existing desktop files (default: False)
--remove-show-in Remove the "OnlyShowIn" and "NotShowIn" entries from the desktop file (default: False)
--remove-key KEY Remove the KEY key from the desktop files, if present
--set-key (KEY VALUE) Set the KEY key to VALUE
--remove-only-show-in ENVIRONMENT Remove ENVIRONMENT from the list of desktop environment where the desktop files should be displayed
--add-only-show-in ENVIRONMENT Add ENVIRONMENT to the list of desktop environment where the desktop files should be displayed
--remove-not-show-in ENVIRONMENT Remove ENVIRONMENT from the list of desktop environment where the desktop files should not be displayed
--add-not-show-in ENVIRONMENT Add ENVIRONMENT to the list of desktop environment where the desktop files should not be displayed
Even when iptables.service is configured to use different file, the
service would not start when there is no /etc/sysconfig/iptables. Fedora
20 package does not provide it.
Instead of overriding /etc/sysconfig/ip{,6}tables, store qubes rules in
/etc/sysconfig/iptables.qubes and configure the service to use that file
instead. This will prevent conflict on that file and also handle upgrades.
A file is created in /var/lib/qubes/protected-files. Scripts can grep this file before modifying
known files to be protected and skip any modifications if the file path is within protected-files.
Usage Example:
if ! grep -q "^/etc/hostname$" "${PROTECTED_FILE_LIST}" 2>/dev/null; then
Also cleaned up maintainer scripts removing unneeded systemd status functions and streamlined
the enable/disable systemd unit files functions
This will probably break some user configuration. Do that only when
installing for the first time (during template build), during upgrade
set only those installed by this package instead of all.
This process should be started from user session (most likely
qubes-session). New processes (of that user) will be created as
children of that session making logind and such crap happy. This should
also solve problems with EOF transmission (no additional "su" process)
and prevent loading all the environment multiple times.
This is to allow permissions to be set on some devices where the user needs
less restrictive permissions. /etc/udev/rules.d/99-qubes-misc.rules changes
a few xen devices to allow the users in the qubes group access
