Subject: [PATCH v2 00/16] block: sed-opal: support shadow MBR done flag and write
Date: Thu, 17 Jan 2019 22:31:40 +0100	[thread overview]
Message-ID: <1547760716-7304-1-git-send-email-zub@linux.fjfi.cvut.cz> (raw)

This patch series extends OPAL support: it adds IOCTL for setting the shadow
MBR done flag which can be useful for unlocking an OPAL disk on boot and it adds
IOCTL for writing to the shadow MBR. Also included are some minor fixes and
improvements.

This series is based on the original work done by Jonas Rabenstein which was
submitted in March 2018.[1] I tried to apply suggestions made in review on the
list and do some further improvements.

The most contentious issue in the original series was the IOCTL for shadow MBR
write but I think no better approach was found[2] so this was not changed. I'm
open to suggestions.

There is a fork of sed-opal-temp that can use these new IOCTLs.[3] I tested
these on Samsung 840 EVO and 850 EVO drives, on x86-64 and arm64 systems.

The series applies on v5.0-rc2.

I'm resending this as v2 because I sent the first attempt incorrectly. I
apologize for the noise.
