## AppArmor
|
|
|
|
As there are a lot of rules, it is recommended to enable caching AppArmor profiles.
|
|
In `/etc/apparmor/parser.conf`, add `write-cache` and `Optimize=compress-fast`.
|
|
|
|
```sh
|
|
echo 'write-cache' | sudo tee /etc/apparmor/parser.conf
|
|
echo 'Optimize=compress-fast' | sudo tee /etc/apparmor/parser.conf
|
|
```
|

## Personal directories
|
|
|
|
This project is designed in such a way that it is easy to personalize the
|
|
directories your programs have access by defining a few variables.
|
|
|
|
The profiles heavily use the (largely extended) XDG directory variables defined
|
|
in the **[Variables Reference](/variables)** page.
|
|
|
|
??? note "XDG variables overview"
|
|
|
|
See **[Variables Reference](/variables)** page for more.
|
|
|
|
| Description | Name | Value |
|
|
|-------------|:----:|---------|
|
|
| Desktop | `@{XDG_DESKTOP_DIR}` | `Desktop` |
|
|
| Download | `@{XDG_DOWNLOAD_DIR}` | `Downloads` |
|
|
| Templates | `@{XDG_TEMPLATES_DIR}` | `Templates` |
|
|
| Public | `@{XDG_PUBLICSHARE_DIR}` | `Public` |
|
|
| Documents | `@{XDG_DOCUMENTS_DIR}` | `Documents` |
|
|
| Music | `@{XDG_MUSIC_DIR}` | `Music` |
|
|
| Pictures | `@{XDG_PICTURES_DIR}` | `Pictures` |
|
|
| Videos | `@{XDG_VIDEOS_DIR}` | `Videos` |
|
|
| Books | `@{XDG_BOOKS_DIR}` | `Books` |
|
|
| Projects | `@{XDG_PROJECTS_DIR}` | `Projects` |
|
|
| Screenshots | `@{XDG_SCREENSHOTS_DIR}` | `@{XDG_PICTURES_DIR}/Screenshots` |
|
|
| Sync | `@{XDG_SYNC_DIR}` | `Sync` |
|
|
| Torrents | `@{XDG_TORRENTS_DIR}` | `Torrents` |
|
|
| Vm | `@{XDG_VM_DIR}` | `.vm`
|
|
| Wallpapers | `@{XDG_WALLPAPERS_DIR}` | `@{XDG_PICTURES_DIR}/Wallpapers` |
|
|
|
|
You can personalize these values by creating a file such as:
|
|
`/etc/apparmor.d/tunables/xdg-user-dirs.d/local` where you define your own
|
|
personal directories. Example:
|
|
```sh
|
|
@{XDG_VIDEOS_DIR}+="Films"
|
|
@{XDG_MUSIC_DIR}+="Musique"
|
|
@{XDG_PICTURES_DIR}+="Images"
|
|
@{XDG_BOOKS_DIR}+="BD" "Comics"
|
|
@{XDG_PROJECTS_DIR}+="Git" "Papers"
|
|
```
|
|
|
|
Then restart the apparmor service to reload the profiles in the kernel:
|
|
```sh
|
|
sudo systemctl restart apparmor.service
|
|
```
|
|
|
|
**Examples**
|
|
|
|
- For git support, you may want to add your `GO_PATH` in the `XDG_PROJECTS_DIR`:
|
|
```sh
|
|
@{XDG_PROJECTS_DIR}+="go"
|
|
```
|
|
- If you use Keepass, personalize `XDG_PASSWORD_STORE_DIR` with your password directory. Eg:
|
|
```sh
|
|
@{XDG_PASSWORD_STORE_DIR}+="@{HOME}/.keepass/"
|
|
```
|
|
- Add pacman integration with your AUR helper. Eg for `yay`:
|
|
```sh
|
|
@{user_pkg_dirs}+=@{user_cache_dirs}/yay/
|
|
```
|
|
|
|
## Local profile extensions
|
|
|
|
You can extend any profile with your own rules by creating a file in the
|
|
`/etc/apparmor.d/local/` directory with the name of your profile. For example,
|
|
to extend the `foo` profile, create a file `/etc/apparmor.d/local/foo` and add
|
|
your rules in it.
|
|
|
|
**Example**
|
|
|
|
- `child-open`, a profile that allows other program to open resources (URL,
|
|
picture, books...) with some predefined GUI application. To allow it to open
|
|
URLs with Firefox, create the file `/etc/apparmor.d/local/child-open` with:
|
|
```sh
|
|
/{usr/,}bin/firefox rPx,
|
|
```
|
|
|
|
!!! note
|
|
|
|
This is an example, no need to add Firefox into `child-open`, it is already there.
|
|
|
|
!!! info
|
|
|
|
`rPx` allows transition to the Firefox profile. Use `rPUx` to allow
|
|
transition to an unconfined state if you do not have the profile for a
|
|
given program.
|
|
|
|
|
|
Then, reload the apparmor rules with `sudo systemctl restart apparmor`.
