This branch introduces a generic TEE framework in the kernel, to handle trusted environemtns (security coprocessor or software implementations such as OP-TEE/TrustZone). I'm sending it separately from the other arm-soc driver changes to give it a little more visibility, once the subsystem is merged, we will likely keep this in the arm₋soc drivers branch or have the maintainers submit pull requests directly, depending on the patch volume. I have reviewed earlier versions in the past, and have reviewed the latest version in person during Linaro Connect BUD17. Here is my overall assessment of the subsystem: * There is clearly demand for this, both for the generic infrastructure and the specific OP-TEE implementation. * The code has gone through a large number of reviews, and the review comments have all been addressed, but the reviews were not coming up with serious issues any more and nobody volunteered to vouch for the quality. * The user space ioctl interface is sufficient to work with the OP-TEE driver, and it should in principle work with other TEE implementations that follow the GlobalPlatform[1] standards, but it might need to be extended in minor ways depending on specific requirements of future TEE implementations * The main downside of the API to me is how the user space is tied to the TEE implementation in hardware or firmware, but uses a generic way to communicate with it. This seems to be an inherent problem with what it is trying to do, and I could not come up with any better solution than what is implemented here.

Ioctl Numbers
|
|
19 October 1999

Michael Elizabeth Chastain
|
|
<mec@shout.net>
|
|
|
|
If you are adding new ioctl's to the kernel, you should use the _IO
|
|
macros defined in <linux/ioctl.h>:
|
|
|
|
_IO an ioctl with no parameters
|
|
_IOW an ioctl with write parameters (copy_from_user)
|
|
_IOR an ioctl with read parameters (copy_to_user)
|
|
_IOWR an ioctl with both write and read parameters.
|
|
|
|
'Write' and 'read' are from the user's point of view, just like the
|
|
system calls 'write' and 'read'. For example, a SET_FOO ioctl would
|
|
be _IOW, although the kernel would actually read data from user space;
|
|
a GET_FOO ioctl would be _IOR, although the kernel would actually write
|
|
data to user space.
|
|
|
|
The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
|
|
or number from the table below. Because of the large number of drivers,
|
|
many drivers share a partial letter with other drivers.
|
|
|
|
If you are writing a driver for a new device and need a letter, pick an
|
|
unused block with enough room for expansion: 32 to 256 ioctl commands.
|
|
You can register the block by patching this file and submitting the
|
|
patch to Linus Torvalds. Or you can e-mail me at <mec@shout.net> and
|
|
I'll register one for you.
|
|
|
|
The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
|
|
to distinguish ioctls from each other. The third argument to _IOW,
|
|
_IOR, or _IOWR is the type of the data going into the kernel or coming
|
|
out of the kernel (e.g. 'int' or 'struct foo'). NOTE! Do NOT use
|
|
sizeof(arg) as the third argument as this results in your ioctl thinking
|
|
it passes an argument of type size_t.
|
|
|
|
Some devices use their major number as the identifier; this is OK, as
|
|
long as it is unique. Some devices are irregular and don't follow any
|
|
convention at all.
|
|
|
|
Following this convention is good because:
|
|
|
|
(1) Keeping the ioctl's globally unique helps error checking:
|
|
if a program calls an ioctl on the wrong device, it will get an
|
|
error rather than some unexpected behaviour.
|
|
|
|
(2) The 'strace' build procedure automatically finds ioctl numbers
|
|
defined with _IO, _IOW, _IOR, or _IOWR.
|
|
|
|
(3) 'strace' can decode numbers back into useful names when the
|
|
numbers are unique.
|
|
|
|
(4) People looking for ioctls can grep for them more easily when
|
|
this convention is used to define the ioctl numbers.
|
|
|
|
(5) When following the convention, the driver code can use generic
|
|
code to copy the parameters between user and kernel space.
|
|
|
|
This table lists ioctls visible from user land for Linux/x86. It contains
|
|
most drivers up to 2.6.31, but I know I am missing some. There has been
|
|
no attempt to list non-X86 architectures or ioctls from drivers/staging/.
