A few reserved fields are not verified to be 0. In preparation for possibly using these fields later we should verify that they are passed as 0. One extra field I do not have confidence in verifying is up.nr in io_register_files_update(). Should this also be checked to be zero? Patch 1 in this series just moves a validation out of __io_register_rsrc_update as it was duplicated Patch 2-4 add verifications for reserved fields Dylan Yudaken (4): io_uring: move io_uring_rsrc_update2 validation io_uring: verify that resv2 is 0 in io_uring_rsrc_update2 io_uring: verify resv is 0 in ringfd register/unregister io_uring: verify pad field is 0 in io_get_ext_arg fs/io_uring.c | 16 ++++++++++++---- 1 file changed, 12 insertions(+), 4 deletions(-) base-commit: 0f8da75b51ac863b9435368bd50691718cc454b0 -- 2.30.2
