From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eric Biggers Subject: [RFC PATCH v2 17/20] ext4: wire up new fscrypt ioctls Date: Mon, 11 Feb 2019 09:27:35 -0800 Message-ID: <20190211172738.4633-18-ebiggers@kernel.org> References: <20190211172738.4633-1-ebiggers@kernel.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20190211172738.4633-1-ebiggers@kernel.org> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: linux-f2fs-devel-bounces@lists.sourceforge.net To: linux-fscrypt@vger.kernel.org Cc: Satya Tangirala , linux-api@vger.kernel.org, linux-f2fs-devel@lists.sourceforge.net, keyrings@vger.kernel.org, linux-mtd@lists.infradead.org, linux-crypto@vger.kernel.org, linux-fsdevel@vger.kernel.org, linux-ext4@vger.kernel.org, Paul Crowley List-Id: linux-api@vger.kernel.org From: Eric Biggers Wire up the new ioctls for adding and removing fscrypt keys to/from the filesystem, and the new ioctl for retrieving v2 encryption policies. For more details see Documentation/filesystems/fscrypt.rst, as well as the fscrypt patches that added the implementation of these ioctls.
