Subject: [PATCH v5 0/3] LSM: security module information improvements Changes from v4: Use kasprintf instead of kzalloc() ... sprintf in more places. More in the documentation. Separate module information in contexts with ",". (not yet visible) Changes from v3: Use kasprintf instead of kzalloc() ... sprintf. Create interfaces that make it possible to deal with process attributes in the face of multiple "major" security modules. Patch 1/3 adds /sys/kernel/security/lsm, which provides a list of the active security modules on the system. $ cat /sys/kernel/security/lsm capability,yama,loadpin,smack Patch 2/3 adds a subdirectory in /proc/.../attr for each security module that exports process attribute data. This allows a program in easily differentiate between the "current" value for Smack and AppArmor. $ cat /proc/self/attr/smack/current System $ cat /proc/self/attr/apparmor/current unconfined Patch 3/3 adds an interface that provides module identified information that otherwise matches the "current" attr. This allows a system with multiple modules to provide the complete security "context" in one place. A (future) system with both Smack and AppArmor might report: $ cat /proc/self/attr/context smack='System',apparmor='unconfined' Signed-off-by: Casey Schaufler <casey@schaufler-ca.com> --- Documentation/security/LSM.txt | 34 ++++++-- fs/proc/base.c | 95 +++++++++++++++++++--- fs/proc/internal.h | 1 + include/linux/lsm_hooks.h | 12 +-- include/linux/security.h | 15 ++-- security/apparmor/lsm.c | 38 +++++++-- security/commoncap.c | 3 +- security/inode.c | 26 +++++- security/loadpin/loadpin.c | 2 +- security/security.c | 177 ++++++++++++++++++++++++++++++++++++++++- security/selinux/hooks.c | 22 ++++- security/smack/smack_lsm.c | 22 ++--- security/tomoyo/tomoyo.c | 2 +- security/yama/yama_lsm.c | 2 +- 14 files changed, 395 insertions(+), 56 deletions(-)
