LoadPin: Initialize as ordered LSM

2019-01-08T21:18:43Z

This converts LoadPin from being a direct "minor" LSM into an ordered LSM. Signed-off-by: Kees Cook Reviewed-by: Casey Schaufler

LoadPin: Rename boot param "enabled" to "enforce"

2018-10-18T22:29:44Z

LoadPin's "enabled" setting is really about enforcement, not whether or not the LSM is using LSM hooks. Instead, split this out so that LSM enabling can be logically distinct from whether enforcement is happening (for example, the pinning happens when the LSM is enabled, but the pin is only checked when "enforce" is set). This allows LoadPin to continue to operate sanely in test environments once LSM enable/disable is centrally handled (i.e. we want LoadPin to be enabled separately from its enforcement).

LoadPin: Report friendly block device name

2018-10-18T22:29:44Z

Instead of only reporting major/minor, include the actual block device name, at least as seen by the kernel. Signed-off-by: Kees Cook

module: replace the existing LSM hook in init_module

2018-07-16T19:31:57Z

Both the init_module and finit_module syscalls call either directly or indirectly the security_kernel_read_file LSM hook. This patch replaces the direct call in init_module with a call to the new security_kernel_load_data hook and makes the corresponding changes in SELinux, LoadPin, and IMA.

security: mark LSM hooks as __ro_after_init

Mark all of the registration hooks as __ro_after_init (via the __lsm_ro_after_init macro). Signed-off-by: James Morris Acked-by: Stephen Smalley Acked-by: Kees Cook

LSM: Add /sys/kernel/security/lsm

2017-01-19T02:18:29Z

I am still tired of having to find indirect ways to determine what security modules are active on a system. I have added /sys/kernel/security/lsm, which contains a comma separated list of the active security modules. No more groping around in /proc/filesystems or other clever hacks. Unchanged from previous versions except for being updated to the latest security next branch.

LSM: LoadPin: provide enablement CONFIG

2016-05-17T10:10:30Z

Instead of being enabled by default when SECURITY_LOADPIN is selected, provide an additional (default off) config to determine the boot time behavior. As before, the "loadpin.enabled=0/1" kernel parameter remains available. Suggested-by: James Morris Signed-off-by: Kees Cook Signed-off-by: James Morris
