[gentoo-user] shared memory

[gentoo-user] shared memory

[Martins Steinbergs]

Hi,

I have problem - user cant access shared memory, got this:

FGLTexMgr: open of shared memory object failed (Permission denied)

fstab has entry:
none /dev/shm defaults 0 0

xorg dri section set to 0666

cant fugure out what has changed and where to look to fix this, any ideas?

Martins

First and for all change defaults to noexec,rw , why would you want 
anyone to be able to execute anything in a volatile fs ?
Second /dev/shm is `as far as I know` only added to be compatible with 
glibc2.2 and above so the POSIX shm_open and shm_unlink can be used, try 
running
touch /dev/shm/foo
if this works then nothing is wrong with /dev/shm or any related 
settings , I think ..

defaults was there for ages and it worked until recent. I'm not sure is it 
good idea, but changed it to users and got things working. will add noexec, 
rw as you sudgest.

thanx
