The highlights are listed below, but all of the patches pass our test suite and merge cleanly against your tree. Please merge for v5.10. - A number of changes to how the SELinux policy is loaded and managed inside the kernel with the goal of improving the atomicity of a SELinux policy load operation. These changes account for the bulk of the diffstat as well as the patch count. A special thanks to everyone who contributed patches and fixes for this work. - Convert the SELinux policy read-write lock to RCU. - A tracepoint was added for audited SELinux access control events; this should help provide a more unified backtrace across kernel and userspace. - Allow the removal of security.selinux xattrs when a SELinux policy is not loaded. - Enable policy capabilities in SELinux policies created with the scripts/selinux/mdp tool. - Provide some "no sooner than" dates for the SELinux checkreqprot sysfs deprecation. Thanks, -Paul --- The following changes since commit 9123e3a74ec7b934a4a099e98af6a61c2f80bbf5: Linux 5.9-rc1 (2020-08-16 13:04:57 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux.git tags/selinux-pr-20201012 for you to fetch changes up to 0d50f059c4cdc9e436f6f4db8779ac0795bfdadf: selinux: provide a "no sooner than" date for the checkreqprot removal (2020-09-29 16:50:57 -0400) ---------------------------------------------------------------- selinux/stable-5.10 PR 20201012 ---------------------------------------------------------------- Colin Ian King (1): selinux: fix allocation failure check on newpolicy->sidtab Dan Carpenter (1): selinux: fix error handling bugs in security_load_policy() Daniel Burgener (4): selinux: Create function for selinuxfs directory cleanup selinux: Refactor selinuxfs directory populating functions selinux: Standardize string literal usage for selinuxfs directory names selinux: Create new booleans and class dirs out of tree Lakshmi Ramasubramanian (1): selinux: Add helper functions to get and set checkreqprot Ondrej Mosnacek (1): selinux: simplify away security_policydb_len() Paul Moore (1): selinux: provide a "no sooner than" date for the checkreqprot removal Peter Enderborg (1): selinux: add basic filtering for audit trace events Randy Dunlap (1): selinux: delete repeated words in comments Stephen Smalley (9): scripts/selinux,selinux: update mdp to enable policy capabilities selinux: encapsulate policy state, refactor policy load selinux: move policy commit after updating selinuxfs selinux: refactor changing booleans selinux: avoid dereferencing the policy prior to initialization selinux: permit removing security.selinux xattr before policy load selinux: convert policy read-write lock to RCU selinux: move policy mutex to selinux_state, use in lockdep checks selinux: access policycaps with READ_ONCE/WRITE_ONCE Thiébaud Weksteen (1): selinux: add tracepoint on audited events kernel test robot (1): selinux: fix memdup.cocci warnings .../ABI/obsolete/sysfs-selinux-checkreqprot | 2 +- MAINTAINERS | 1 + include/trace/events/avc.h | 53 ++ scripts/selinux/mdp/mdp.c | 7 + security/selinux/avc.c | 29 +- security/selinux/hooks.c | 17 +- security/selinux/include/conditional.h | 2 +- security/selinux/include/policycap.h | 20 + security/selinux/include/policycap_names.h | 18 + security/selinux/include/security.h | 63 +- security/selinux/selinuxfs.c | 259 ++++-- security/selinux/ss/avtab.c | 49 +- security/selinux/ss/avtab.h | 1 + security/selinux/ss/conditional.c | 155 ++++ security/selinux/ss/conditional.h | 2 + security/selinux/ss/hashtab.c | 53 ++ security/selinux/ss/hashtab.h | 6 + security/selinux/ss/services.c | 875 ++++++++++------- security/selinux/ss/services.h | 5 +- security/selinux/ss/sidtab.c | 10 + security/selinux/ss/sidtab.h | 2 + 21 files changed, 1130 insertions(+), 499 deletions(-) create mode 100644 include/trace/events/avc.h create mode 100644 security/selinux/include/policycap.h create mode 100644 security/selinux/include/policycap_names.h
