Subject: [RFC PATCH 6/9] io_uring: convert io_uring to the secure anon inode interface
Date: Fri, 21 May 2021 17:50:19 -0400 [thread overview]
Message-ID: <162163381908.8379.10800711368185383459.stgit@sifl> (raw)
In-Reply-To: <162163367115.8379.8459012634106035341.stgit@sifl>
Converting io_uring's anonymous inode to the secure anon inode API
enables LSMs to enforce policy on the io_uring anonymous inodes if
they chose to do so. This is an important first step towards
providing the necessary mechanisms so that LSMs can apply security
policy to io_uring operations.
