reorganizing links browsers

[pirate486743186]

they are a bunch of variants of links

created links-common.profile
adapted links, elinks
fixed xlinks
added links2, xlinks2

EDITED

[rusty-snake]

xlinks looks problematic, rest is LGTM.

LGTM

[rusty-snake]

doesn't use /tmp/.X11-unix

Can you prove that this is always the case?

unresolved/new question

[pirate486743186]

originally xlinks.profile had this too "noblacklist ${HOME}/.links"
it wasn't exactly a high quality profile

wikipedia works fine
you can tell the program is using the bare minimum, in order to have its own window

Having a redundant line does not make every line wrong.

wikipedia works fine

On your system because it uses a TCP-Socket/Abstract-Unix-Socket (try with --net=none/--net=eth0). /tmp/.X11-unix is the location of the X11 (non-abstract) unix-socket (https://unix.stackexchange.com/questions/196677/what-is-tmp-x11-unix).

Can you prove that this is always the case? Either by providing the relevant parts of the source-code or by testing on various systems/configures/….

$ links -version
Links 2.20.2
$ firejail --private links -g https://wikipedia.org/
# Works
$ firejail --private --blacklist=/tmp/.X11-unix links -g https://wikipedia.org/
# Works
$ firejail --private --blacklist=/tmp/.X11-unix --net=wlp... links -g https://wikipedia.org/
Could not initialize any graphics driver. Tried the following drivers:
x:
Can't open display ":0"
fb:
Could not get VT mode.

EDIT:

firejail --private --net=wlp2s0 links -g https://wikipedia.org/ does not work either. But we blacklist /tmp/.X11-unix for some reasons and the "old" profile has it. Need to check more.

EDIT2:

Test with mpv:

$ firejail --noprofile --blacklist='${RUNUSER}/wayland-*' mpv …
# Works
$ firejail --noprofile --blacklist='${RUNUSER}/wayland-*' --net=none mpv …
# Works
$ firejail --noprofile --blacklist='${RUNUSER}/wayland-*' --blacklist=/tmp/.X11-unix mpv …
# Works
$ firejail --noprofile --blacklist='${RUNUSER}/wayland-*' --blacklist=/tmp/.X11-unix --net=none mpv …
# No window

Summary: Many factors that influence/condition each other.
