The response from the kernel group is that this should *not* be mounted automatically at boot; feel free to mount it if you need it. Oh, I am suprised: I made the filesystem, worked with the glibc group that they use it for POSIX shm, the kernel docs say also it should be mounted, but you think it is not needed :-( I believe there are concerns about it a) working correctly b) being used for simple DoS attacks At a) You rely on SYSV shm in some applications? They use the same fs but kern_mounted. I am pretty sure it works better than any shm implementation we had in the 2.x timeframe. At b) You could use the mount option nr_blocks, or on an -ac kernel the mount otion size to protect against that. |
