Subject: shmget with SHM_HUGETLB flag: Operation not permitted
Date: Thu, 26 Feb 2004 23:36:03 +0100	[thread overview]
Message-ID: <403E74D3.4000305@roemling.net> (raw)

Hi,

I'm using stock kernel 2.6.2. I have HUGETLB support compiled in.

CONFIG_HUGETLBFS=y
CONFIG_HUGETLB_PAGE=y

When issuing this command in a C pgm

shmid =shmget(IPC_PRIVATE, SOMESIZE, SHM_HUGETLB|IPC_CREAT|SHM_R|SHM_W)

I get "Operation not Permitted" when running it as a normal user. It
works for root. Without the SHM_HUGETLB flag it works fine for all users.

How can I grant the permission to use HUGETLB to ordinary users?


Jochen
