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
(enable/disable them in appropriate VM types) is much simpler and less
error prone than automatic generators.
Handling code is implemented in qubes-session-autostart, which is called
from qubes-session.

Fedora now needs this sudoer rule. Allows sudo to keep the `QT_X11_NO_MITSHM` ENV
variable which prevents MIT-SHM errors for Fedora and Debian when running a QT
application:
`Defaults env_keep += "QT_X11_NO_MITSHM"`
A complementary commit has been made in gui-agent-linux:

There were multiple problems with reusing existing one:
- need to sync with upstream changes (configuration path etc)
- conflicts resolution on updates
- lack of iptables --wait, which causes firewall fail to load sometimes
QubesOS/qubes-issues#1067
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
Moved iptables configuration to /usr/lib/qubes/init
fc21 + debian + arch will place them in proper place on postinst
Fixes dedian bug of not having them in proper place
Instead of directly using Exec= line, parse the file (at the launch
time) with Gio library. The main reason for this change is to handle
Terminal= option, but generally this approach should be more
bulletproof, especially when some fancy options are present in desktop
files.
It would be called by qvm-sync-clock instead of 'date' directly. This
gives a lot of flexibility - VM can control whether it want to sync time
this way. For now slight corrections (+-2sec) are ignored to not cause
problems by frequent time changes. But it can be easily extended to
refuse time sync when some other mechanism is used.
* use 127.0.1.1 under debian (since it's the default there)
* also set the IPv6 loopback address (::1) since some tools tries to
AAAA resolve the hostname (for example sendmail)
* ensure proper /etc/hosts format through postinst-script (hostname as
last entry)
It looks to be related to this report:
https://bugzilla.redhat.com/show_bug.cgi?id=1088619
Workaround idea was from comment 37.
The hanging process in Qubes VM is most likely dconf-service, but there
is a lot of possible causes. To start with a non-standard method of
accessing the X session (no real login manager, processes started by
qrexec-agent). So instead of wasting a lot of time on digging through
gnome services, simply shorten the stop timeout - the processes would be
killed anyway.
Since d660f260b8 icon is hidden during VM
startup for non-netvm. Because qubes-session handles tasks sequentially,
move that one earlier to not scary the user with ghost icon.
This better handles dependencies (especially of "Obsolete:" type).
Unfortunately yum install/upgrade checks if running as root. Because we
are only downloading packages, using local "system root" (--installroot
option) no real root access is requires, so use fakeroot to mute yum
error.
This time it is for cups, which have socket-based and path-based
activators. When activator tires to start the service which is disabled
by condition file it enters infinite loop (as service wont start, but
will not report an error).
This reverts commit 047a7a0b23.
Actually some g-s-d plugins are helpful, for example notification of low
disk space. Also we've already disabled keyboard plugin.
MIME-info database contains multiple entries for *.png, namely image/png
and image/x-apple-ios-png. The later one doesn't have associated handler
program, but this one is selected by mimeopen tool.
Not sure how this tool should behave in case of multiple matches (IOW is
it a bug in File::MimeInfo perl module used by mimeopen). Instead of
switching to different tool, which probably will break other files
(check #423), add override for this particular file type.
Whitelist any rules file with qubes in name. This will prevent further
mistakes like forgetting about some script, or even not including script
for another package (like qubes-tor currently).
Get rid of underscores in filenames, use dashes instead.
This is first part of cleanup in filenames.
"qubes_rpc" still untouched - will be in separate commit.
No more ugly symlink creation at VM startup, nautilus-actions have system-wide
dir (in opposite to nautilus-scripts).
Currently old symlinks are not cleaned up. Maybe it should, but leaving them
have one advantage: will not break existing users behavior.
Upgrade of kernel is suppressed by qubes-vm-kernel-placeholder package.
Excluding xorg packages makes more problems than goods (e.g. unable to
install dummy driver, block fedora bugfixes).
%setup macro must be present in %prep to set variables required by
find-debuginfo script. Symlink is to place sources in nice
/usr/src/debug/%{name}-%{version} subdir instead of plain /usr/src/debug/core
(which can be ambiguous).
Additionally all packages need to have _builddir pointing at top src dir (in
core-dom0 it was dom0 subdir). And to cheat make about current dir (to have
%{name}-%{version} included in path) chdir must be done by shell, not make - so
can't use make -C.
This libs are required by both dom0 and VM so it's better to have it
separately. Previously in VM it was separate package, but dom0 have them
embedded in qubes-core-dom0, but qubes-core-vm-libs package was used to build
qubes-gui-dom0. Now we do not build all packages for all distros (especially do
not build core-vm package for dom0 distro, so gui-dom0 build fails), so make it
explicit which package is needed by which system.
Some packages depends on kernel (ex fuse, pulseaudio), but kernel in VM is
managed by dom0. Any hack like exlude or so on will break some things, so
install empty placeholder package to fulfill dependencies.
1. Try to use NetworkManager sleep command instead of shutting it down
2. Move sleep action details (which is VM-specific) to VM
3. Export it as qrexec service(s)
Actually all /etc/pam.d/ files containing pam_systemd.so are autogenerated by
authconfig, so "removing" pam_systemd.so file as not elegant solution, seems to
be much more realiable.
The simplest way is just add proxy=... entry to /etc/yum.conf, but sometimes it
is reasonable to bypass the proxy. Some examples:
- usage of non-standard repos with some exotic file layout, which will be
blocked by the proxy
- usage of repos not-accessible via proxy (eg only via VPN stared in VpnVM)
This commit introduces 'yum-proxy-setup' pseudo-service, which can be
controlled via standard qvm-service or qubes-manager. When enabled - yum will
be configured at VM startup to use qubes proxy, otherwise - to connect directly
(proxy setting will be cleared).
Introduce proxy service, which allow only http(s) traffic to yum repos. The
filter rules are based on URL regexp, so it isn't full-featured content
inspection and can be easy bypassed, but should be enough to prevent some
erroneus user actions (like clicking on invalid link).
It is set up to intercept connections to 10.137.255.254:8082, so VM can connect
to this IP regardless of VM in which proxy is running. By default it is
started in every NetVM, but this can be changed using qvm-service or
qubes-manager (as always).
In FC15, NetworkManager by default uses global connections ("Available to all users"). Save them in /rw instead of /etc, to preserve them across reboots.
This will work when device is unmounted. On mounted device backend will be
removed (after 3s timeout), but frontend will left in "closing" state - manual
'xl block-detach' will be needed.
It is build upon qrexec2, qubes.VMShell command. So, in order to e.g.
start firefox in a fresh dispVM, do
qvm-run '$dispvm' firefox http://www.qubes-os.org
Get kernel from global kernels dir (/var/lib/qubes/vm-kernels), not per-VM. Can
be configured by qvm-prefs (kernel parameter).
New tool: qvm-set-default-kernel
For backward compatibility kernel=None means kernel in VM dir (kernels subdir).
(possibly empty) modules.img should be created in it.
Mainly 4 parts:
- scripts for providing rpmdb and yum repos to VM (choosen by qvm-set-updatevm)
- VM script for downloading updates (qubes_download_dom0_updates.sh)
- qfile-dom0-unpacker which receive updates, check signatures and place its in dom0 local yum repo
- qvm-dom0-upgrade which calls all of above and after all yum gpk-update-viewer
Besides qvm-dom0-upgrade, updates are checked every 6h and user is prompted if
want to download it. At dom0 side gpk-update-icon (disabled yet) should notice
new updates in "local" repo.
After yum transaction (install/upgrade/remove),
yum-plugin-post-transaction-actions will execute script which trigger
qvm-sync-appmenus in dom0 (through qrexec).
THIS INTRODUCE NEW PREDEFINED COMMAND IN QREXEC
Ex. gpk-application needs this to work properly while running from user. When
root password is set - polkit-daemon asks for it (according to polkit setting).
Move unneded /etc/init/*.conf services to /etc/init/*.conf.disabled.
Start CUPS only in AppVM and UtilityVM.
Start XDG Autostart applications only in domains that makes sense for them.
