1. Deal with .purple directory. It holds the confiig files for pidgin

2. Startup warnings on Arch Linux:

(all fine here)
$ ./firejail
Parent pid 2495, child pid 2496
Child process initialized
$

(warnings)
$ ./firejail --overlay
Parent pid 2500, child pid 2501
OverlayFS configured in /home/ablive/.firejail/2500 directory
Warning: /var/lock not mounted
Warning: cannot find /var/run/utmp
Warning: failed to unmount /sys
Child process initialized
$ 

(warnings)
$ ./firejail --chroot=/media/mylinux
Parent pid 2503, child pid 2504
Warning: cannot find /var/run/utmp
Dropping all Linux capabilities and enforcing default seccomp filter
Warning: failed to unmount /sys
Child process initialized
$

3. Remove private.keep in 0.9.34 release (deprecated in 0.9.30)

4. Remove exclude-token from profile include in 0.9.34 (deprecated in 0.9.30)

5. Add IRC clients: KVIrc (KDE), BitchX (CLI), Smuxi, Konversation (KDE), HexChat, Irssi (CLI), WeeChat (CLI)
RSS: Liferea, akregator (KDE), newsbeuter (CLI), rawdog, 

6. Tests not working on Arch:
profile_syntax.exp (profile syntax)
fs_chroot.exp (chroot as user)
private-etc.exp

7. Disable /dev/tcp in bash. Compiled time: --enable-net-redirections, --disable-net-redirections
ksh and zsh seem to have it.

Tests:
a)
cat </dev/tcp/time.nist.gov/13

b)
exec 3<>/dev/tcp/www.google.com/80
echo -e "GET / HTTP/1.1\r\nhost: http://www.google.com\r\nConnection: close\r\n\r\n" >&3
cat <&3

c) A list of attacks

8. SELinux

"desktops are notoriously difficult to use a mandatory access control system on"

9. blacklist .muttrc, contains passwords in clear text

10. abstract unix socket bridge, example for ibus:

before the sandbox is started
socat UNIX-LISTEN:/tmp/mysoc,fork ABSTRACT-CONNECT:/tmp/dbus-awBoQTCc &

in sandbox
socat ABSTRACT-LISTEN:/tmp/dbus-awBoQTCc,fork UNIX-CONNECT:/tmp/mysock

11. autotest for config options:

./configure --enable-fatal-warnings --prefix=/usr
./configure --enable-fatal-warnings --disable-seccomp --prefix=/usr
./configure --enable-fatal-warnings --disable-chroot --prefix=/usr
./configure --enable-fatal-warnings --disable-bind --prefix=/usr
