Bug 140064

I think pretty much all the files and directories that the GTK+ port web process needs to access are generic enough that they should most likely be whitelisted for EFL as well. I'd like to add several locations to the web process whitelist: * /lib64 and /usr/lib64: nothing has any chance of working on x86_64 Linux otherwise, except on Debian which doesn't have these directories. * /run/user/UID where UID is the result of getuid(), since at-spi2 creates lots of random directories here. (I'd rather this be more restrictive.) I think at-spi2 is not specific to GTK+. * Specific files in /sys/fs/cgroup, for the memory pressure handler that landed last month. (These accesses will fail regardless because those files are owned by root. Not sure how the memory pressure handler is supposed to work.) * Check $XDG_DATA_HOME before assuming that mime types are in ~/.local/share/mime * /var/tmp -- this is unfortunate, but with recent enough mesa (for DRI3) and barring a configure-time override (which Debian wisely does), shared memory winds up here: https://bugzilla.redhat.com/show_bug.cgi?id=1172869 * mesa configuration files * Various directories needed by udev * ~/nv for the NVIDIA proprietary driver, suggested by Zan. * Tempted to also put gstreamer stuff here.... We can talk about whether any of these locations should be moved to the GTK+ and/or EFL whitelists instead.
