Hi, There is a problem with /run/user/ and /dev/shm. Ordinary users can write to /run/user/<login> dirs filling entire free space. This can lead to local DoS. Additional information can be found in this thread http://lists.freedesktop.org/archives/systemd-devel/2011-April/thread.html#1839 Best regards, Michal
There's no way quota support for tmpfs can be ready in time for F15.
I realize that it is not a 10 lines bugfix :) Thanks for the consideration of the problem.
I guess you're not expecting this to be fixed for F15, then? Moving to rawhide so the problem can be considered properly.

So f15 is history, any news about this bug/rfe?
No change in tmpfs. What has changed is that Fedora now creates a tmpfs for each /run/user/<uid> login with a maximum size. This mitigation sort of covers up the problem. the /dev/shm issue appears to still be present.
