Hi,
I was using firefox within sandboxes for a while without perm. home directory. To store bookmarks, addons and so on, I started to use perm. homedir (-H).
Because firefox does not allow multiple concurrent sessions (lock on .mozilla) it is not possible to open multiple websites when specifying the same sandbox homedir, hence I'm looking for a possibility to open new websites within a running sandbox from outside.
Without sandboxes everyone can open new websites in a running firefox instance using: firefox -remote "openurl(http://www.mozilla.org)"
sandbox scenario:
- step:
start firefox: sandbox -X -H homedir -T tempdir -t sandbox_web_t -l s0:c100,c100 firefox
- step:
sandbox -H homedir -T tempdir -t sandbox_web_t -l s0:c100,c100 firefox -remote "openurl(http://www.mozilla.org)"
My current attempts fail because I'm unable use the '-l' option (#632377) but would the policy allow the 'firefox -remote' command if type and security level matches with the already running sandbox?
kind regards, Christoph

I have gotten this to work, but it is not pretty.
I created a file in homedir called firefox.sh
It looks like
cat homedir/firefox.sh #!/bin/sh DISPLAY=:1.0 /usr/bin/firefox -remote "openurl($1)"
Then
sandbox -H ~/sandbox/homedir -T ~/sandbox/tempdir -t sandbox_web_t -l s0:c100 /bin/sh ~/firefox.sh http://www.redhat.com
Seems to work.
The key thing is figuring out the DISPLAY.
A possible solution would be to change the /usr/share/sandbox/sandboxX.sh To the attached.
Which creates a ~/seremote application within homedir that looks like
#!/bin/sh -x DISPLAY=:1 $*
:1 will be different for each additional sandbox.
Then you could execute
sandbox -H ~/sandbox/homedir -T ~/sandbox/tempdir -t sandbox_web_t -l s0:c100 /bin/sh ~/seremote firefox -remote "openurl(http://www.redhat.com)"
And it will work.
I will have to make policy changes to allow
sandbox -H ~/sandbox/homedir -T ~/sandbox/tempdir -t sandbox_web_t -l s0:c100 ~/seremote firefox -remote "openurl(http://www.redhat.com)"
to work.
