Tight Firejail profiles

This is a collection of tighter firejail (https://github.com/netblue30/firejail) profiles for certain applications. These may or may not work on your computer since some of them use seccomp filters, which may depend on architecture and OS. These were designed on Debian sid/experimental x86_64.

I am slowly switching the profiles to use a common.inc file so that maintenance becomes easier and I cut down on duplicate stuff.

Just a note: I would highly recommend using systemd to sandbox system processes. I personally do not use firejail to sandbox system processes since I'm using systemd to start the process anyway (so it's easier to use the sandboxing capabilities of systemd itself).

Currently there is one utility file in this repository: gen_libraries. gen_libraries is a collection of bash functions which helps dynamically resolve the libraries needed by a program in a more powerful way than the built-in one shipped with firejail. Most pertinently, it allows passing a folder as the first argument, in which case it will use find to locate all files within the folder and run ldd on each of them. This makes it easier, say, to compile a list for firefox.

An example script, firefox.common, which makes use of gen_libraries is provided in this repository as well. You should edit $FXLIBDIR and $GENLIB to point to your firefox lib directory (defaults to /usr/lib/firefox) and the gen_libraries script (default ~/scripts/gen_libraries) or disable private-lib generation by setting $PRIVLIB to 0. The script has the following features:

• It can simply load a profile (pass the path to the profile as the first argument and 0 as the second and third arguments).
• It can create a temporary profile which is completely empty (pass the path to any profile as the first argument, 1 as the second argument, and 0 as the third argument).
• It can create a temporary profile and copy over files from another profile (pass the path to the profile which you wish to copy files from as the first argument and 1 as the second and third arguments). You can edit the list of files and folders to be copied over by editing the $TOCOPY variable.

You can disable the systemd specific parts of the script by setting $USE_SYSTEMD to 0. You may also need to edit the list of additional libraries (the second argument to compile_list), since that list is what works for me on my system but may not be enough on yours.

Another example script, dropbox, is also provided which uses gen_libraries to dynamically generate the library dependencies needed to get dropbox working with a private-lib filter.

Yet another example script, google-earth-pro, is provided which uses gen_libraries to dynamically generate the library dependencies needed to get google-earth-pro working with a private-lib filter. Also note that due to some issues with google-earth-pro, the script manually removes the lock file generated by Google Earth after quitting.
