As promised, here is revision #3 of the io_uring/LSM/audit patchset. The changes from revision #2 are minimal and noted in the individual patches; they are mostly focused on removing debug/dev code and scary "BEWARE, DEVELOPMENT PATCH!" language from the commit descriptions. With plenty of good discussion happening on the initial RFC posting, and the second revision incorporating all the feedback garnering no objections, I plan to merge this patchset into the selinux/next tree later this week. Jens, Pavel, it would nice if I could get your ACK on the io_uring patches before I merge them. For those of you who may be seeing this for the first time, the second RFC revision of the patchset can be found in the archives at the link below: https://lore.kernel.org/linux-security-module/162871480969.63873.9434591871437326374.stgit@olly/ ... and the initial draft RFC can be found here: https://lore.kernel.org/linux-security-module/162163367115.8379.8459012634106035341.stgit@sifl/ Those who would prefer to fetch these patches directly from git can do so using the tree/branch below: git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux.git (checkout branch "working-io_uring") -Paul --- Casey Schaufler (1): Smack: Brutalist io_uring support with debug Paul Moore (7): audit: prepare audit_context for use in calling contexts beyond syscalls audit,io_uring,io-wq: add some basic audit support to io_uring audit: add filtering for io_uring records fs: add anon_inode_getfile_secure() similar to anon_inode_getfd_secure() io_uring: convert io_uring to the secure anon inode interface lsm,io_uring: add LSM hooks to io_uring selinux: add support for the io_uring access controls fs/anon_inodes.c | 29 ++ fs/io-wq.c | 4 + fs/io_uring.c | 69 +++- include/linux/anon_inodes.h | 4 + include/linux/audit.h | 26 ++ include/linux/lsm_hook_defs.h | 5 + include/linux/lsm_hooks.h | 13 + include/linux/security.h | 16 + include/uapi/linux/audit.h | 4 +- kernel/audit.h | 7 +- kernel/audit_tree.c | 3 +- kernel/audit_watch.c | 3 +- kernel/auditfilter.c | 15 +- kernel/auditsc.c | 477 ++++++++++++++++++++++------ security/security.c | 12 + security/selinux/hooks.c | 34 ++ security/selinux/include/classmap.h | 2 + security/smack/smack_lsm.c | 46 +++ 18 files changed, 654 insertions(+), 115 deletions(-)
