[PATCH v2 0/3] Split security_task_getsecid() into subj and obj variants

An update on the previous RFC patchset found here: https://lore.kernel.org/linux-security-module/161377712068.87807.12246856... Aside from being rebased to the current SELinux next branch (which in turn is based on v5.12-rc2), this revision changes the binder related code to always use the objective credentials as discussed in the thread above. I've also dropped the AppArmor patch as John has a better version in progress; in the meantime AppArmor should continue to work exactly as it did before this patchset so there is no harm in merging this without the AppArmor patch. Casey, John, and Richard; I dropped your ACKs, Reviewed-by, etc. tags as the binder changes seemed substantial enough to not carryover your tags. I would appreciate it if you could re-review this revision; the changes should be minimal. I did leave Mimi's tag on this revision as she qualified it for IMA and that code didn't change. --- Paul Moore (3): lsm: separate security_task_getsecid() into subjective and objective variants selinux: clarify task subjective and objective credentials smack: differentiate between subjective and objective task credentials security/selinux/hooks.c | 112 ++++++++++++++++++++++++------------- security/smack/smack.h | 18 +++++- security/smack/smack_lsm.c | 40 ++++++++----- 3 files changed, 117 insertions(+), 53 deletions(-)
