drm/panel: Changes for v3.16-rc1
This set of commits contains a couple of fixes to existing panel drivers
and support for some new panels.
One commit touches the DRM core in that in modifies the MIPI DSI support
to hook up the shutdown function so that drivers can provide code that's
run on shutdown. This is used by a subsequent commit to make the simple
panel driver power off the backlight on shutdown.

drm/tegra: Changes for v3.16-rc1
The majority of these changes are a slew of cleanups across the board.
A more noteworthy change is the addition of drm_dev_set_unique() and the
conversion of the Tegra DRM driver to use it. This allows us to get rid
of the host1x drm_bus implementation. Other USB and platform drivers can
be changed in a similar way. Unfortunately for most PCI devices there is
some userspace that relies on the old functionality and cannot be as
easily converted.
HDMI and hardware cursor support is added for Tegra124. The SOR output
gains support for exposing CRCs via debugfs, which can be used for
automated testing. Many values that were hardcoded in the SOR/eDP code
are now computed at runtime to increase compatibility with more devices.

Pull the parameter checking from drm_primary_helper_update() out into
its own function; drivers that provide their own setplane()
implementations rather than using the helper may still want to share
this parameter checking logic.
A few of the checks here were also updated based on suggestions by
Ville Syrjälä.
v3:
- s/primary_helper/plane_helper/ --- this checking logic may be useful
for other types of planes as well.
- Fix visibility check (need to dereference visibility pointer)
v2:
- Pass src/dest/clip rects and min/max scaling down to helper to avoid
duplication of effort between helper and drivers (suggested by
Ville).
- Allow caller to specify whether the primary plane should be
updatable while the crtc is disabled.

For atomic, it will be quite necessary to not need to care so much
about locking order. And 'state' gives us a convenient place to stash a
ww_ctx for any sort of update that needs to grab multiple crtc locks.
Because we will want to eventually make locking even more fine grained
(giving locks to planes, connectors, etc), split out drm_modeset_lock
and drm_modeset_acquire_ctx to track acquired locks.
Atomic will use this to keep track of which locks have been acquired
in a transaction.

After the split-out of crtc locks from the big mode_config.mutex
there's still two major areas it protects:
- Various connector probe states, like connector->status, EDID
properties, probed mode lists and similar information.
- The links from connector->encoder and encoder->crtc and other
modeset-relevant connector state (e.g. properties which control the
panel fitter).
The later is used by modeset operations. But they don't really care
about the former since it's allowed to e.g. enable a disconnected VGA
output or with a mode not in the probed list.
Thus far this hasn't been a problem, but for the atomic modeset
conversion Rob Clark needs to convert all modeset relevant locks into
w/w locks. This is required because the order of acquisition is
determined by how userspace supplies the atomic modeset data. This has
run into troubles in the detect path since the i915 load detect code
needs _both_ protections offered by the mode_config.mutex: It updates
probe state and it needs to change the modeset configuration to enable
the temporary load detect pipe.
The big deal here is that for the probe/detect users of this lock a
plain mutex fits best, but for atomic modesets we really want a w/w
mutex. To fix this lets split out a new connection_mutex lock for the
modeset relevant parts.
For simplicity I've decided to only add one additional lock for all
connector/encoder links and modeset configuration states. We have
piles of different modeset objects in addition to those (like bridges
or panels), so adding per-object locks would be much more effort.
Also, we're guaranteed (at least for now) to do a full modeset if we
need to acquire this lock. Which means that fine-grained locking is
fairly irrelevant compared to the amount of time the full modeset will
take.
I've done a full audit, and there's just a few things that justify
special focus:
- Locking in drm_sysfs.c is almost completely absent. We should
sprinkle mode_config.connection_mutex over this file a bit, but
since it already lacks mode_config.mutex this patch wont make the
situation any worse. This is material for a follow-up patch.
- omap has a omap_framebuffer_flush function which walks the
connector->encoder->crtc links and is called from many contexts.
Some look like they don't acquire mode_config.mutex, so this is
already racy. Again fixing this is material for a separate patch.
- The radeon hot_plug function to retrain DP links looks at
connector->dpms. Currently this happens without any locking, so is
already racy. I think radeon_hotplug_work_func should gain
mutex_lock/unlock calls for the mode_config.connection_mutex.
- Same applies to i915's intel_dp_hot_plug. But again, this is already
racy.
- i915 load_detect code needs to acquire this lock. Which means the
w/w dance due to Rob's work will be nicely contained to _just_ this
function.
I've added fixme comments everywhere where it looks suspicious but in
the sysfs code. After a quick irc discussion with Dave Airlie it
sounds like the lack of locking in there is due to sysfs cleanup fun
at module unload.
v1: original (only compile tested)
v2: missing mutex_init(), etc (from Rob Clark)
v3: i915 needs more care in the conversion:
- Protect the edp pp logic with the connection_mutex.
- Use connection_mutex in the backlight code due to
get_pipe_from_connector.
- Use drm_modeset_lock_all in suspend/resume paths.
- Update lock checks in the overlay code.

It was possible to get a setuid root or setcap executable to write to
it's stdout or stderr (which has been set made a netlink socket) and
inadvertently reconfigure the networking stack.
To prevent this we check that both the creator of the socket and
the currentl applications has permission to reconfigure the network
stack.
Unfortunately this breaks Zebra which always uses sendto/sendmsg
and creates it's socket without any privileges.
To keep Zebra working don't bother checking if the creator of the
socket has privilege when a destination address is specified. Instead
rely exclusively on the privileges of the sender of the socket.
Note from Andy: This is exactly Eric's code except for some comment
clarifications and formatting fixes. Neither I nor, I think, anyone
else is thrilled with this approach, but I'm hesitant to wait on a
better fix since 3.15 is almost here.
Note to stable maintainers: This is a mess. An earlier series of
patches in 3.15 fix a rather serious security issue (CVE-2014-0181),
but they did so in a way that breaks Zebra. The offending series
includes:
commit aa4cf9452f469f16cea8c96283b641b4576d4a7b
Author: Eric W. Biederman <ebiederm@xmission.com>
Date: Wed Apr 23 14:28:03 2014 -0700
net: Add variants of capable for use on netlink messages
If a given kernel version is missing that series of fixes, it's
probably worth backporting it and this patch. if that series is
present, then this fix is critical if you care about Zebra.

well as the asid_cache and branch emulation fixes which fix corruption
or possible uninteded behaviour of kernel or application code. The
remainder of fixes are more platforms or subsystem specific"

Pull networking fixes from David Miller:
"It looks like a sizeble collection but this is nearly 3 weeks of bug
fixing while you were away.
1) Fix crashes over IPSEC tunnels with NAT, the latter can reroute
the packet through a non-IPSEC protected path and the code has to
be able to handle SKBs attached to routes lacking an attached xfrm
state. From Steffen Klassert.
2) Fix OOPSs in ipv4 and ipv6 ipsec layers for unsupported
sub-protocols, also from Steffen Klassert.
3) Set local_df on fragmented netfilter skbs otherwise we won't be
able to forward successfully, from Florian Westphal.
4) cdc_mbim ipv6 neighbour code does __vlan_find_dev_deep without
holding RCU lock, from Bjorn Mork.
5) local_df test in ip_may_fragment is inverted, from Florian
Westphal.
6) jme driver doesn't check for DMA mapping failures, from Neil
Horman.
7) qlogic driver doesn't calculate number of TX queues properly, from
Shahed Shaikh.
8) fib_info_cnt can drift irreversibly positive if we fail to
allocate the fi->fib_metrics array, from Sergey Popovich.
9) Fix use after free in ip6_route_me_harder(), also from Sergey
Popovich.
10) When SYSCTL is disabled, we don't handle local_port_range and
ping_group_range defaults properly at all, from Cong Wang.
11) Unaccelerated VLAN tagged frames improperly handled by cdc_mbim
driver, fix from Bjorn Mork.
12) cassini driver needs nested lock annotations for TX locking, from
Emil Goode.
13) On init error ipv6 VTI driver can unregister pernet ops twice,
oops. Fix from Mahtias Krause.
14) If macvlan device is down, don't propagate IFF_ALLMULTI changes,
from Peter Christensen.
15) Missing NULL pointer check while parsing netlink config options in
ip6_tnl_validate(). From Susant Sahani.
16) Fix handling of neighbour entries during ipv6 router reachability
probing, from Duan Jiong.
17) x86 and s390 JIT address randomization has some address
calculation bugs leading to crashes, from Alexei Starovoitov and
Heiko Carstens.
18) Clear up those uglies with nop patching and net_get_random_once(),
from Hannes Frederic Sowa.
19) Option length miscalculated in ip6_append_data(), fix also from
Hannes Frederic Sowa.
20) A while ago we fixed a race during device unregistry when a
namespace went down, turns out there is a second place that needs
similar protection. From Cong Wang.
21) In the new Altera TSE driver multicast filtering isn't working,
disable it and just use promisc mode until the cause is found.
From Vince Bridgers.
22) When we disable router enabling in ipv6 we have to flush the
cached routes explicitly, from Duan Jiong.
23) NBMA tunnels should not cache routes on the tunnel object because
the key is variable, from Timo Teräs.
24) With stacked devices GRO information in skb->cb[] can be not setup
properly, make sure it is in all code paths. From Eric Dumazet.
25) Really fix stacked vlan locking, multiple levels of nesting with
intervening non-vlan devices are possible. From Vlad Yasevich.
26) Fallback ipip tunnel device's mtu is not setup properly, from
Steffen Klassert.
27) The packet scheduler's tcindex filter can crash because we
structure copy objects with list_head's inside, oops. From Cong
Wang.
28) Fix CHECKSUM_COMPLETE handling for ipv6 GRE tunnels, from Eric
Dumazet.
29) In some configurations 'itag' in __mkroute_input() can end up
being used uninitialized because of how fib_validate_source()
works. Fix it by explitly initializing itag to zero like all the
other fib_validate_source() callers do, from Li RongQing"
