Branches[edit]

Introduction[edit]

While the project is small adrelanos thinks it is best not to make a too difficult policy.

Compare[edit]

Upstream git issue. Currently not easy to compare tags in a superproject while showing what changed in the submodules.

git log -p --submodule=log 15.0.0.3.3-stable..15.0.0.3.7-developers-only

master[edit]

  • Adrelanos's progress of work.
  • Not calling it unstable, because the changes will most likely never make it unstable but it is just not tested if it still builds.
  • Branching model, project readme, information, gpg...

signed git tags[edit]

Releases will be tagged and gpg signed.

Link to Source Code[edit]

https://github.com/Whonix/Whonix [archive]


subscribe to code changes[edit]

git[edit]

Git clone github [archive].

A git specific work flow could be:

git fetch

every (few) day(s) and then git diff(tool), merge, etc.

rss feed notification[edit]

https://github.com/Whonix/Whonix/commits/master.atom [archive]

manually in your browser[edit]

Check every now and then https://github.com/Whonix/Whonix/commits/master [archive].

Github Commits Mailing List[edit]

Currently not in use. Please get in contact if that interests you.

Whonix ™-commits read only mailing list [archive]

(Stay hosted on sourceforge.net. Barely anyone is signed up and it is quite high traffic.)

Twitter[edit]

If you prefer Twitter, use the Secondary Twitter Account for Source Code Commit Notification [archive]. Using third party service to forward git commits to twitter. Might not be reliable.


grep Whonix ™ source code[edit]

Introduction[edit]

greping the Whonix ™ source code can be useful when looking for certain keywords. However, a common grep -r will show lots of irrelevant search results due to changelog files, license files and git history. The following is a suggestions on how to securely acquire Whonix ™ source code as well as on greping the Whonix ™ with relevant only relevant search results.

Get the Source Code[edit]

Get the Signing Key[edit]

Info This step is recommended for better security, but is not strictly required. (See Trust.)

Get the Whonix ™ Signing Key.

Ambox warning pn.svg.png Note: By proceeding, you acknowledge that you have read, understood and agreed to our Terms of Service and License Agreement. Ambox warning pn.svg.png

Install git.

sudo apt-get update && sudo apt-get install git

Get the source code including git submodules. [1] [2]

Note: Replace 15.0.1.9.3-stable with the actual tag you want to build.

git clone --depth=1 --branch 15.0.1.9.3-stable --jobs=4 --recurse-submodules --shallow-submodules https://gitlab.com/whonix/Whonix.git

OpenPGP Verify the Source Code[edit]

Info This chapter is recommended for better security, but is not strictly required. [3]

Git fetch. [4]

git fetch

Verify the chosen tag to build. Replace with tag you want to build.

Note: Replace 15.0.1.9.3-stable with the actual tag you want to build.

git verify-tag 15.0.1.9.3-stable

The output should look similar to this.

object 1844108109a5f2f8bddcf2257b9f3675be5cfb22

type commit tag 15.0.1.9.3 tagger Patrick Schleizer <adrelanos@whonix.org> 1392320095 +0000

. gpg: Signature made Thu 13 Feb 2014 07:34:55 PM UTC using RSA key ID 77BB3C48

gpg: Good signature from "Patrick Schleizer <adrelanos@whonix.org>" [ultimate]

warning Check the GPG signature timestamp makes sense. For example, if you previously saw a signature from 2021 and now see a signature from 2020, then this might be a targeted rollback (downgrade) or indefinite freeze attack. [5]

The warning.

gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.

Is explained on the Whonix Signing Key page and can be safely ignored.

By convention, git tags should point to signed git commits. [6] (forum discussion [archive]) It is advisable to verify the signature of the git commit as well (replace 15.0.1.9.3 with the actual git tag being verified).

git verify-commit 15.0.1.9.3-stable^{commit}

The output should look similar to this.

commit 5aa1c307c943be60e7d2bfa5727fa5ada3a79c4a

gpg: Signature made Sun 07 Dec 2014 01:22:22 AM UTC using RSA key ID 77BB3C48 gpg: Good signature from "Patrick Schleizer <adrelanos@whonix.org>" [ultimate] Author: Patrick Schleizer <adrelanos@whonix.org> Date: Sun Dec 7 01:22:22 2014 +0000

.

Choose Version[edit]

Retrieve a list of available git tags.

git --no-pager tag

Use git checkout to select the preferred version to build.

Note: Replace 15.0.1.9.3-stable with the actual tag you want to build.

git checkout --recurse-submodules 15.0.1.9.3-stable

Check Git[edit]

Check if you really got the version you want.

git describe

The output should show.

15.0.1.9.3-stable

Check if the source folder is pristine.

git status

The output should show nothing.

HEAD detached at 15.0.1.9.3-stable
nothing to commit, working tree clean

If it shows something else, do not continue.

grep the source code[edit]

Create folder ~/bin.

mkdir ~/bin

Create a file ~/bin/mygrep. Paste the following.

#!/bin/bash
set -x
exec \
grep \
--exclude=README.md \
--exclude=GPLv2 \
--exclude=GPLv3 \
--exclude=COPYING \
--exclude=changelog.upstream-old1 \
--exclude-dir=mnt \
--exclude-dir=qubes-src/linux-template-builder/mnt \
--exclude=changelog.upstream \
--exclude-dir=".git" \
--exclude-dir=chroot-debian \
--exclude-dir=chroot-buster "$@"

Save.

chmod +x ~/bin/mygrep

Make executable.

cd Whonix

Search for string. For example grub-pc.

mygrep -r -i grub-pc


Compiled Code[edit]

find . -name '*.c' -not -iwholename '*.git*'

./sdwdate/usr/lib/sdwdate/sclockadj.c
./bindp/usr/lib/bindp.c
./kloak/src/main.c
./kloak/src/keycodes.c
./kloak/src/eventcap.c

Put folder under Git Version Control[edit]

Update the package lists.

sudo apt-get update

Install git.

sudo apt-get install --no-install-recommends git

Unless you want to use git for pushing changes to remotes which you probably won't in a testing VM you can use the following git config without using any real names or pseudonyms. (These are the git suggested defaults. [7])

git config --global user.email "you@example.com"

git config --global user.name "Your Name"

Desalinize git in current folder or cd to any folder you want to put under git version control. Can even be done for /home/user folder which is very useful.

git init

Add all files to be added for next commit.

git add -A

Actually commit to git.

git commit -a -m .

Check git status of that folder.

git status

No changes registered yet to the folder since just now committed all to git.

On branch master
nothing to commit, working tree clean

Create a test file or do some activity such as starting a browser or e-mail client.

touch test-file

Check again git status of that folder.

git status

Now git will show what changed.

On branch master
Untracked files:
  (use "git add <file>..." to include in what will be committed)

	test-file

nothing added to commit but untracked files present (use "git add" to track)

Goodies[edit]

Optional. Just sharing. Like it or not.

You need to enable deb-src in /etc/apt/sources.list.d/derivative.list!

Footnotes[edit]

  1. Optional git parameters:
    • --depth=1: Used to speed up download.
    • --branch 15.0.1.9.3-stable Usability. Used to speed up download.
    • --jobs=4: Used to speed up download.
    • --recurse-submodules --shallow-submodules: Usability.
    Knowledgeable git users are free to drop any of these optional parameters.
  2. Alternatively, this can be achieved with the following commands in several steps. This is useful if network issues arise.
    git clone --depth=1 --branch 15.0.1.9.3-stable https://gitlab.com/whonix/Whonix.git

    cd Whonix

    git submodule update --init --recursive --progress --jobs=4

  3. See Trust.
  4. Optional. [...]
  5. As defined by TUF: Attacks and Weaknesses:
  6. Beginning from git tag 9.6 and above.
  7. git commit -a -m .
    
    *** Please tell me who you are.
    
    Run
    
      git config --global user.email "you@example.com"
      git config --global user.name "Your Name"
    
    to set your account's default identity.
    Omit --global to set the identity only in this repository.
    
    fatal: empty ident name (for <(null)>) not allowed
