Subject: [PATCH 00/25] fscrypt: add some higher-level helper functions
Date: Wed, 20 Sep 2017 15:45:40 -0700 [thread overview]
Message-ID: <20170920224605.22030-1-ebiggers3@gmail.com> (raw)
From: Eric Biggers <ebiggers@google.com>
This series reduces code duplication among ext4, f2fs, and ubifs by
introducing a S_ENCRYPTED inode flag (so we don't have to call back into
the filesystem to test the filesystem-specific inode flag), then
introducing new helper functions that are called at the beginning of the
open, link, rename, lookup, and setattr operations.
In the future we maybe should even call these new helpers from the VFS
so that each individual filesystem doesn't have to do it. But that's
not possible currently because fs/crypto/ can be built as a module.
Making changes like this is a bit challenging due to interdependencies
between fscrypt and the individual filesystems, all of which have
different maintainers. For now my intent is that patches 1-10 be taken
through the fscrypt tree --- though it's not perfect since patches 1-4
do make some changes to each filesystem, as everyone must set
S_ENCRYPTED before we can use it everywhere in the shared code. But
afterwards, patches 11-25 can be picked up by the individual filesystems
to switch to the new helpers.
Eric Biggers (25):
fs, fscrypt: add an S_ENCRYPTED inode flag
fscrypt: switch from ->is_encrypted() to IS_ENCRYPTED()
fscrypt: remove ->is_encrypted()
fscrypt: remove unneeded empty fscrypt_operations structs
fscrypt: new helper function - fscrypt_require_key()
fscrypt: new helper function - fscrypt_file_open()
fscrypt: new helper function - fscrypt_prepare_link()
fscrypt: new helper function - fscrypt_prepare_rename()
