Hello,

I use Ubuntu 10.10 with encrypted home. I'm new with apparmor.


My firefox-3.6.13 is now in enforce mode - with standard profile.
With this profile it should have write access only to:
owner @{HOME}/Downloads/* rw,

but I can save files (with standard downloadmanager of firefox) e.g. in $HOME itself and I can't find any other rule, which could allow that. I have thing, that ecryptfs workaround just affects the eCryptFS "part of things" and limitations of normal filenames/paths (in mounted ecryptfs) are still possible.

----------------------------------------------------------------------------------------
So ... why can firefox write elsewhere as in to ${HOME}/Downloads ?
----------------------------------------------------------------------------------------

BTW: I get also this in kern.log (but not by saving a file as wrote above) :

Feb 27 05:49:30 duron650 kernel: [ 2284.886631] type=1400 audit(1298782170.190:48): apparmor="DENIED" operation="open" parent=1782 profile="/usr/lib/firefox-3.6.13/firefox-*bin" name="/home/.ecryptfs/hugo/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWY1tHLaOszg1UQTPB2f1Zq7Xu 0xztwk9hVX6-OCUaSGk2nU5ADkJx.rdk--/ECRYPTFS_FNEK_ENCRYPTED.FWY1tHLaOszg1UQTPB2f1Zq7Xu 0xztwk9hVXFlmP1qlJBZ2eq7XFiWljUE--" pid=2209 comm="firefox-bin" requested_mask="w" denied_mask="w" fsuid=1000 ouid=0

?? why do firefox try to write to it and why do it fail even with #13 workaround?

?? Why try firefox to access X lock ?

Thanks for help
