Subject: [PATCH 0/4] io_uring: verify that reserved fields are 0
Date: Tue, 12 Apr 2022 09:30:38 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
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
