Ugh. And it works on normal user in 2.4.0!
There *have* to be some security implications of this.
Okay, this one:
Lets assume home and tmp are periodically backed up; there's quota on
them. I (the evil user) do
pavel@bug:/tmp$ ~/mount -t bind /proc delme2
pavel@bug:/tmp$ cd delme2/
1/ 114/ 43/ 91/ cmdline fs/
ksyms net/ sys/
100/ 119/ 45/ 93/ cpuinfo ide/
loadavg partitions sysvipc/
101/ 120/ 5/ 95/ devices
interrupts locks pci tty/
102/ 13/ 6/ 97/ dma iomem
meminfo scsi/ uptime
That will surely confuse hell out of the backup utility. It is
probably going to confuse autoclean.
Being able to do that is nice; but I feel it should be default to
root-only in 2.4.0.
