[PATCH v3 0/7] Add explicit capability checking

by Luca Vizzarro

Hi again, v3 is here for the explicit capability checking series regarding the issue #7[1]. Patch series tested, with CI and locally, and passing with flying colours, this can also be found on my fork[2]. Kind regards, Luca [1] https://git.morello-project.org/morello/kernel/linux/-/issues/7 [2] https://git.morello-project.org/Sevenarth/linux/-/commits/morello/gup-check… v3: - rebased onto morello/next - amended commit description for "gup: Add explicit capability checks" - refactored mm/gup.c - refactored lib/iov_iter.c - removed bpf patch - moved USB Request Block explicit check to proc_do_submiturb - removed explicit check in get_futex_key - changed prototype of io_uring_cmd_import_fixed and io_import_fixed to use a pointer type and adjusted the relevant castings - fixed io_uring_cmd_import_fixed prototype for !defined(CONFIG_IO_URING) - refactored explicit check in io_uring/kbuf.c:io_register_pbuf_ring(..) - removed explicit check from io_uring/kbuf.c:io_add_buffers(..) - rephrased the no explicit check needed note in io_sqe_buffer_register - reverted "struct io_mapped_ubuf" to use u64 - removed explicit check from io_uring_cmd_prep - updated TODO for the NVMe driver Luca Vizzarro (7): gup: Add explicit capability checks iov_iter: Add explicit capability checks usb: core: Fix copy of URB from userspace usb: core: Add explicit capability checks futex: Add explicit capability checks io_uring: Add explicit capability checks nvme: Add TODO for PCuABI implementation drivers/nvme/host/ioctl.c | 1 + drivers/usb/core/devio.c | 7 +++++-- include/linux/io_uring.h | 6 +++--- include/linux/pagemap.h | 2 +- io_uring/kbuf.c | 26 ++++++++++++++------------ io_uring/net.c | 3 +-- io_uring/rsrc.c | 18 +++++++++++++++--- io_uring/rsrc.h | 2 +- io_uring/rw.c | 3 +-- io_uring/uring_cmd.c | 2 +- kernel/futex/core.c | 11 ++++++++--- lib/iov_iter.c | 26 ++++++++++++++++++++++---- mm/gup.c | 6 ++++-- 13 files changed, 77 insertions(+), 36 deletions(-) -- 2.34.1
