Subject: [PATCH v5 04/16] fs: uapi: define verity bit for FS_IOC_GETFLAGS
Date: Thu, 20 Jun 2019 13:50:31 -0700 [thread overview]
Message-ID: <20190620205043.64350-5-ebiggers@kernel.org> (raw)
In-Reply-To: <20190620205043.64350-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
Add FS_VERITY_FL to the flags for FS_IOC_GETFLAGS, so that applications
can easily determine whether a file is a verity file at the same time as
they're checking other file flags. This flag will be gettable only;
FS_IOC_SETFLAGS won't allow setting it, since an ioctl must be used
instead to provide more parameters.
This flag matches the on-disk bit that was already allocated for ext4.
