Qubes Persistence[edit]

Table: Qubes R4 Inheritance and Persistence

Inheritance [1] Persistence [2]
TemplateVM n/a Everything
TemplateBasedVM /etc/skel/ to /home/ /rw/ (includes /home/ and bind-dirs)
DVM Template [3] /etc/skel/ to /home/ /rw/ (includes /home/ and bind-dirs)
DisposableVM /rw/ (includes /home/ and bind-dirs) Nothing

Debian Template[edit]

bind-dirs vs Tor[edit]

Does bind-dirs will be run before /lib/systemd/system/tor@default.service?

Yes.

qubes-mount-dirs.service has Before=local-fs.target, which it ordered before sysinit.target. After=sysinit.target in turns is included by default (unless DefaultDependencies=noDefaultDependencies=no).

Config Files Changes[edit]

source

I don't know how rpm packaging works. However, the TorVM rpm packaging seems simpler to me and introduce less overhead than Debian packaging at first view. Is there something like config-package-dev for Fedora? config-package-dev is a package to overtake ownership of other > package's files. Such as, in Debian the Tor package owns /usr/share/tor/tor-service-defaults-torrc. Whonix needs to modify that file and keep it updated. config-package-dev can be used to avoid getting the file being overwritten when upstream releases and upgrade. Is there something like this for Fedora or is this even required? That would make a port much simpler, because for many parts, it is just diverted config files.

qubes-tor pacakages provides own config file (tor --defaults-torrc option used), so no need to override the one provided by tor package.

But to answer your question - no, rpm do not have option to take ownership of files from other packages, but to workaround this (rather sensible) limitation you can modify the config in triggers (so the file will be modified after each original package update).

IPs[edit]

source

Qubes uses non-fixed LAN IPs? How do internal LAN IPs get assigned to TorVM / AppVMs?

QubesVm IP address is generated based on its netvm ID (subnet number) and the said VM static ID, so unless user is switching netvm, the IP is pretty static. We've chosen 10.137.<subnet-id>.<vm-id> which is quite exotic so conflicts with real LAN are very rare (even if rather harmless in isolated network).

Tor Browser[edit]

source

In your Torless TBB launcher script for use with Qubes' transparent Tor proxy, TOR_SOCKS_HOST=10.137.3.1. Is this supposed to be the same for all Qubes machines regardless of how many ProxyVMs users have created (or other user settings)? Or is the user supposed to change this before using the script?

Perhaps it is good idea to add some firewall rule in TorVM to redirect traffic to any 10.137.0.0/16 IP + port 9050/9049 to the tor running in TorVM. This way AnonVM can use any IP as a sock proxy address.

Run updates over Proxy/Tor[edit]

source

Without wasting a lot space, having lots of standalone VMs... How could one persistently install software in QubesOS using package managers over Tor just for a specific VM? Routing all traffic over Tor is also an option, but not a ideal one either (having some clearnet traffic is better for various reasons).

Set TorVM as netvm for the template. By default template updates are routed via "update proxy" (simple http proxy, which allow access only to yum-repository-like sites). This proxy is running in netvm, so after TorVM. Because of that its you need to disable 'yum-proxy-setup' service for this template and allow some traffic in the firewall settings. Or enable 'qubes-yum-proxy' service in TorVM and ensure that its traffic goes through tor.

Time Sync[edit]

Introduction[edit]

Discussion about insecurity of NTP:
https://groups.google.com/d/msg/qubes-devel/YHK_rAUm0s0/ARrBPHrf0fkJ

source

Can Qubes OS leave VM's clocks untouched and keep time sync to the VM or is there some forced-VM-timesync-with-dom-0 that can not be turned off? In that case, that would be a bad.

Currently time synchronization is done in some silly way: qvm-sync-clock called each 6min from dom0 cron. That tool fetch the current time using ntpdate in netvm (VM set as clockvm in qubes-prefs), then pass the result to 'date -s' in each VM.

You can disable this mechanism globally by unsetting(*) clockvm (qubes-prefs -s clockvm none).

(*) Which apparently was broken, fix will be included in updates soon.

Instructions[edit]

UNTESTED!

Install a comfortable editor (optional!).

sudo qubes-dom0-update kate

Edit your VM settings. (Feel free to drop 'EDITOR=kate' and/or to use an editor of your choice.)

sudo EDITOR=kate virsh edit whonix-ws

Find the following block.

<clock offset='utc' adjustment='reset'>
   <timer name='tsc' mode='native'/>
</clock>

Replace it with the following.

  <clock offset='utc'>
    <timer name='rtc' tickpolicy='catchup' track='guest'/>
    <timer name='xen' present='no'/>
  </clock>

How big is Qubes OS's user base?[edit]

IP Spoofing Protection[edit]

source

AppVMs can't spoof each other in Qubes' network.

Corollary: stream isolation cannot be circumvented.

Inter-VM Networking[edit]

Current Qubes + Whonix implementation has both the Whonix-Gateway and Whonix-Workstation connected to the same backend FirewallVM and iptables forwarding is manually established between the Whonix IP addresses. This current method is really just an efficient hack for our initial Qubes + Whonix implementation. The native/proper way to network VMs in Qubes is via chaining their networking "backend" together, which is part of Xen networking structure. This is how other VMs in Qubes are networked, including TorVM. According to Qubes devs, these Xen backends provide simple point-to-point networking between VMs. So this would be advantageous for further isolation of inter-VM Whonix traffic, since, currently, all inter-VM traffic is routed through the internet-facing FirewallVM, which can also be shared by other VMs. This current implementation with a shared FirewallVM could be somewhat of a security concern for inter-VM traffic, and a reason to move to native/proper isolated point-to-point "backend" networking. Also, in the future, it is desirable to leverage full ProxyVM/ServiceVM networking between Whonix-Gateway and Whonix-Workstation, as the TorVM does. ProxyVM utilizes Xen "backend" networking but automates it with transparent Qubes GUI networking, making use of dynamically created virtual networking interfaces. Whonix may need to add onto or adjust its internal networking setup to be compatible with such native Qubes networking.

IP[edit]

grep -r 10.152.152.10 *[edit]

packages/anon-ws-leaktest/usr/lib/leaktest-workstation/simple_ping.py:target = "10.152.152.10"

Let's make a patch adding command line support implementing either --qubes or --ip?

packages/whonixcheck/usr/lib/whonixcheck/preparation:      GATEWAY_IP="10.152.152.10"
packages/whonixcheck/usr/lib/whonixcheck/preparation:      GATEWAY_IP="10.152.152.10"

Overruleable. These variables get only set there if they are not yet set. So they can be manipulated by using environment variables, or better by dropping a config snippet to /etc/whonix.d/40_qubes, /etc/whonix.d/40_qubes that contains: export GATEWAY_IP="<qubes-ip>"
(Make that 40_qubes_autogenerated if the file gets autogenerated.)

packages/anon-kde-streamiso/usr/share/anon-kde-streamiso/share/config/kioslaverc:socksProxy=http://10.152.152.10 9122

We could implement a package anon-kde-streamiso-qubes, that overrules anon-kde-streamiso and that gets only installed when using --qubes. (KDE config files are stackable although debuging is a bit cumbersome.) We'd just have to make sure the path to anon-kde-streamiso-qubes comes (before or after?) anon-kde-streamiso's path in the KDEDIRS envrionment variable.

Or we could install either anon-kde-streamiso or anon-kde-streamiso-qubes (--qubes) depending on which build switch is being used.

packages/anon-kde-streamiso/debian/control: settings are set, for KDE applications to socks 10.152.152.10:9122.

Not overrulable. Unfortunatly Tor does not support variables in config files. Should I (Patrick) make a feature request against Tor?

If you could use static IPs, we could fall back to use Debian packaging's patching mechanism. But that would be burdensome maintenance wise. Because there would be need for a separate qubes repository, that always has the patch applied. Or users would always have to upgrade from source code, which seems inconvenient. Or can we think of something else?

Misc[edit]

Random facts.

  • AdminVM is a synonym for dom0 [4].
  • AdminVM is not based on Fedora Template VM. More like a standalone VM.
  • Qubes Q3 RC1 AdminVM is based on Fedora 20. [5]
  • Qubes Q3 RC1 Fedora Template VM is based on Fedora 21.

tb-updater vs TemplateVM[edit]

prerequisite knowledge[edit]

  • TPO stands for The Tor Project
  • The /home folder of a TemplateVM is copied to a TemplateBasedVM at creation time of the TemplateBasedVM. From then, TemplateBasedVM's /home folder is left untouched. (Source: https://groups.google.com/forum/#!topic/qubes-users/WwVJhGA-Xnc)
  • Tor Browser installation path in Whonix 12 will change to ~/.tb. (https://phabricator.whonix.org/T338)
  • Since Qubes-Whonix 11, Tor Browser gets installed by default for new images. (Not for in place upgrades.)
  • Tor Browser Updater (Whonix) (((https://github.com/Whonix/tb-updater))) vs
  • Tor Browser Internal Updater
  • Tor Browser Updater (Whonix) is unable to keep user settings (modifications such as bookmarks). It renames the old folder. Adds ".old.$(date)". So nothing is lost. Then installs a fresh one. Something important to know. This limitation can probably not be lifted in tb-updater. Upgrading Tor Browser is hard. (TPO often changed the folder layout in past.) That's what Tor Browser's internal updater is for.
  • No one has demonstrated yet, that it is possible to install & run and/or update TBB to either /usr/*, /opt/* or anything of that sort. This is because within the TBB folder, by TPO default, binaries and user data is mixed. (It is a portable application. [Portable with a meaning similar to portableapps.com. Portable on USB drives or similar. Not platform, arm + anything portable.])
  • By TPO default, users are supposed to have TBB in their home folder.
  • It is very unlikely, that TBB will be available as regular deb package anytime soon. [6]
  • A quick an dirty packaging of TBB would likely require too much maintenance effort. [Needs keeping up with upstream releases.]
  • Packaging TBB is further complicated, because TBB abuses Firefox's user settings mechanism for configuring anonymity related settings. (Firefox prefs) Therefore separation of binaries and user data is difficult.
  • Once TBB is in user's home folder... [as TPO wants it] [and it does not work otherwise]... And once the user used it... And once the user stored settings there that the user cares about... [bookmarks, etc...] It gets very difficult for the TemplateVM and/or tb-updater to keep the TBB folder up to date. That's what Tor Browser Internal Updater is for.
    • Unfortunately, this means, if a user had for example 5 different Qubes-Whonix-Workstation based AppVMs where Tor Browser is in use, the user would have to update each of its 5 TBBs using Tor Browser Internal Updater.
    • This is an issue, because Qubes updates are already complicated. (Various templates and dom0 needs to be updated.) This adds another layer of complexity. Users also have to care about updating stuff from within their AppVMs, which is counter intuitive.
    • TBB stable has automatic updates enabled by default. [7]

Implementation as of Qubes-Whonix 11[edit]

  • As of Qubes-Whonix 11 it is confusing. Running tb-updater in the TemplateVM and restarting AppVM won't result in up to date TBB's. [Since if the TemplateVM modifies /home, this will not propagate to AppVM's /home.]

Brainstorming[edit]

Headless TBB Internal Updater Updates in AppVMs[edit]

We could call a qrexec service that starts TBB in each individual AppVM heedlessly (without / with hidden gui, using xvfb or similar) so it will be fetching updates.

up to date versions of Tor Browsers in newly created AppVMs inherited from updated TemplateVMs[edit]

ship Tor Browser tarballs in Qubes TemplateVMs in /var/cache/tb-binary and extract in AppVMs at boot time to user's home folder:
https://phabricator.whonix.org/T417

keep as is[edit]

Newly created Qubes-Whonix-Workstation AppVMs inherit the TBB version that came pre-installed in the Qubes-Whonix-Workstation TemplateVM. From there, TBB's internal updater keeps care of updating it.

  • create tarball from the source dir
  • fill version in `.spec.in` (writing it into `.spec` file)

Qubes VM Manger Firewall Tab Settings[edit]

(screenshot)

Short:
Have no effect for Qubes-Whonix VMs. Can be ignored.

Long [10]:
All that settings are in separate file in the VM directory - dom0 /var/lib/qubes/appvms/whonix/firewall.xml. If the VM is running, those settings are converted to iptables syntax and loaded into QubesDB of directly connected ProxyVM. The qubes-firewall service in the ProxyVM watch for such changes and applies the rules.

I.e. in case of Whonix, the connected ProxyVM is sys-whonix. Since in Whonix qubes-firewall service is disabled (Whonix 12 [11]), these settings do not affect Whonix. (qubes-whonix-firewall.service is what Whonix uses.)

Whonix TemplateVMs[edit]

Inside Whonix TemplateVMs, the following command is run will be run.

Qubes R3.2[edit]

curl_output="$(UWT_DEV_PASSTHROUGH="1" curl --silent --connect-timeout 10 "${PROXY_SERVER}")" || true

After the variables are substituted, the command actually run will be the following.

curl_output="$(UWT_DEV_PASSTHROUGH="1" curl --silent --connect-timeout 10 "http://10.137.255.254:8082/" || true

To simulate (test) this, run the following command.

UWT_DEV_PASSTHROUGH="1" curl --silent --connect-timeout 10 "http://10.137.255.254:8082/" ; echo $?

Should output the following.

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

That output gets `grep`ed for PROXY_META, i.e. for.

If that matches, the whonix-secure-proxy Qubes service is activated. In other words, the /var/run/qubes-service/whonix-secure-proxy status file is being created.

Qubes VM debug mode[edit]

Quote Marek https://forums.whonix.org/t/whonix-live-mode/3894/36

Works only with HVM (on PVH or PV you don’t have emulated VGA). Also it enables more verbose logging - shouldn’t affect performance, but syslog in the VM may be hard to read in some cases. No other disadvantages.

See table at the bottom of https://www.qubes-os.org/news/2018/01/24/qsb-37-update/

VM type \ Qubes OS version         | 3.2 | 4.0-rc1-3 | 4.0-rc4 |
---------------------------------- | --- | --------- | ------- |
Default VMs without PCI devices    | PV  |    HVM    |   PVH   |

Conclusion: Qubes VM debug mode is not the way to go since in Qubes R4 the default for most VMs (that is VMs without PCI devices) (which includes Whonix) is PHV, since these don't have emulated VGA.

Qubes R3.2[edit]

TODO: document

Qubes R4[edit]

This is whatsudo qubesctl state.sls qvm.anon-whonix does in effect. [12] It does not only do what qvm.anon-whonix does, since salt resolves dependencies. In other words, qvm.anon-whonix starts a chain reaction that includes all of the following.

  • install packages from qubes-templates-community
    • install qubes-template-{{{{whonix-gw}}}}
    • install qubes-template-whonix-ws-14
  • create VM called sys-whonix

qvm-tags[edit]

Introduction[edit]

Qubes R4.0 and above only.

Qubes dom0 package qubes-core-admin-addon-whonix (__init__.py) (forum discussion) is responsible for:

  • set NetVM to sys-whonix [...]
  • set default DispVM set to whonix-ws-dvm [...]
  • set tag anon-vm
  • set tag anon-gateway

Qubes dom0 package qubes-mgmt-salt-dom0-virtual-machines will depend on qubes-core-admin-addon-whonix, therefore ensuring it will be installed. (T792) (#3881)

The template package qubes-whonix ships script /etc/qubes/post-install.d/30-whonix-ws.sh, which contains qvm-features-request whonix-ws=1, which is parsed by dom0 package qubes-core-agent-linux qubes RPC qubes.PostInstall.

As per Marek, qvm-features-request whonix-ws=1 should not be set by salt.

Missing Whonix tags anon-vm / anon-gateway will be added.

anon-vm tag[edit]

anon-vm gets prepended to /etc/qubes-rpc/policy/qubes.GetDate by salt template-whonix-ws.sls. Or maybe in future simpler by just adding it.

Tags are not reliably set yet. TODO: https://github.com/QubesOS/qubes-issues/issues/4155 - That is something doable. But it's not a big deal for now since Qubes VMs have many ways to ask dom0 for the non-randomized time.

Tags will be more important in future for sdwdate-gui-qubes but that is more usability, not security.

anon-gateway tag[edit]

anon-gateway tag will be used in future by sdwdate-gui-qubes.

whonix-updatevm tag[edit]

whonix-updatevm tag gets set by salt template-whonix-ws.sls as well as by qubes-core-admin-addon-whonix __init__.py. TODO: /etc/qubes-rpc/policy/qubes.UpdatesProxy

- $tag:whonix-updatevm $default allow,target=sys-whonix
      - $tag:whonix-updatevm $anyvm deny
