selinux: fix residual uses of current_security() for the SELinux blob

2019-10-07T16:59:31Z

[ Upstream commit 169ce0c081cd85f78388bb6c1638c1ad7b81bde7 ] We need to use selinux_cred() to fetch the SELinux cred blob instead of directly using current->security or current_security(). There were a couple of lingering uses of current_security() in the SELinux code that were apparently missed during the earlier conversions. IIUC, this would only manifest as a bug if multiple security modules including SELinux are enabled and SELinux is not first in the lsm order. After this change, there appear to be no other users of current_security() in-tree; perhaps we should remove it altogether.

LSM: Infrastructure management of the ipc security blob

2019-01-08T21:18:45Z

Move management of the kern_ipc_perm->security and msg_msg->security blobs out of the individual security modules and into the security infrastructure. Instead of allocating the blobs from within the modules the modules tell the infrastructure how much space is required, and the space is allocated there.
