From 7191adff2a5566efb139c79ea03eda3d0520d44a Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 22 Mar 2018 21:08:27 -0500 Subject: shm/security: Pass kern_ipc_perm not shmid_kernel into the shm security hooks All of the implementations of security hooks that take shmid_kernel only access shm_perm the struct kern_ipc_perm member. This means the dependencies of the shm security hooks can be simplified by passing the kern_ipc_perm member of shmid_kernel.. Making this change will allow struct shmid_kernel to become private to ipc/shm.c. Signed-off-by: "Eric W.
