ovl: automatically enable redirect_dir on metacopy=on

2018-11-21T08:19:13+00:00

commit d47748e5ae5af6572e520cc9767bbe70c22ea498 upstream.

Current behavior is to automatically disable metacopy if redirect_dir is
not enabled and proceed with the mount.

If "metacopy=on" mount option was given, then this behavior can confuse the
user: no mount failure, yet metacopy is disabled.

This patch makes metacopy=on imply redirect_dir=on.

The converse is also true: turning off full redirect with redirect_dir=
{off|follow|nofollow} will disable metacopy.

If both metacopy=on and redirect_dir={off|follow|nofollow} is specified,
then mount will fail, since there's no way to correctly resolve the
conflict.

media: replace ADOBERGB by OPRGB

2018-11-13T19:08:54+00:00

commit db0340182444612bcadb98bdec22f651aa42266c upstream.

The CTA-861 standards have been updated to refer to opRGB instead
of AdobeRGB. The official standard is in fact named opRGB, so
switch to that.

The two old defines referring to ADOBERGB in the public API are
put under #ifndef __KERNEL__ and a comment mentions that they are
deprecated.

media: cec: add new tx/rx status bits to detect aborts/timeouts

2018-11-13T19:08:53+00:00

commit 7ec2b3b941a666a942859684281b5f6460a0c234 upstream.

If the HDMI cable is disconnected or the CEC adapter is manually
unconfigured, then all pending transmits and wait-for-replies are
aborted. Signal this with new status bits (CEC_RX/TX_STATUS_ABORTED).

If due to (usually) a driver bug a transmit never ends (i.e. the
transmit_done was never called by the driver), then when this times
out the message is marked with CEC_TX_STATUS_TIMEOUT.

This should not happen and is an indication of a driver bug.

Without a separate status bit for this it was impossible to detect
this from userspace.

The 'transmit timed out' kernel message is now a warning, so this
should be more prominent in the kernel log as well.

crypto: speck - remove Speck

2018-11-13T19:08:46+00:00

commit 578bdaabd015b9b164842c3e8ace9802f38e7ecc upstream.

These are unused, undesired, and have never actually been used by
anybody. The original authors of this code have changed their mind about
its inclusion. While originally proposed for disk encryption on low-end
devices, the idea was discarded [1] in favor of something else before
that could really get going. Therefore, this patch removes Speck.

Code of Conduct: Change the contact email address

2018-10-22T06:33:36+00:00

The contact point for the kernel's Code of Conduct should now be the
Code of Conduct Committee, not the full TAB.  Change the email address
in the file to properly reflect this.

Code of Conduct Interpretation: Add document explaining how the Code of Conduct is to be interpreted

2018-10-22T06:33:35+00:00

The Contributor Covenant Code of Conduct is a general document meant to
provide a set of rules for almost any open source community.  Every
open-source community is unique and the Linux kernel is no exception.
Because of this, this document describes how we in the Linux kernel
community will interpret it.  We also do not expect this interpretation
to be static over time, and will adjust it as needed.

This document was created with the input and feedback of the TAB as well
as many current kernel maintainers.
