block/sed-opal: Introduce free_opal_dev to free the structure and clean up state

2017-02-23T18:55:41+00:00

Before we free the opal structure we need to clean up any saved
locking ranges that the user had told us to unlock from a suspend.

block/sed-opal: allocate struct opal_dev dynamically

2017-02-17T19:41:47+00:00

Insted of bloating the containing structure with it all the time this
allocates struct opal_dev dynamically.  Additionally this allows moving
the definition of struct opal_dev into sed-opal.c.  For this a new
private data field is added to it that is passed to the send/receive
callback.  After that a lot of internals can be made private as well.

Move stack parameters for sed_ioctl to prevent oversized stack with CONFIG_KASAN

2017-02-15T02:47:18+00:00

When CONFIG_KASAN is enabled, compilation fails:

block/sed-opal.c: In function 'sed_ioctl':
block/sed-opal.c:2447:1: error: the frame size of 2256 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

Moved all the ioctl structures off the stack and dynamically allocate
using _IOC_SIZE()

block: Add Sed-opal library

2017-02-06T16:44:19+00:00

This patch implements the necessary logic to bring an Opal
enabled drive out of a factory-enabled into a working
Opal state.

This patch set also enables logic to save a password to
be replayed during a resume from suspend.
