Andrey reported a use-after-free in add_grec():
for (psf = *psf_list; psf; psf = psf_next) {
...
psf_next = psf->sf_next;
where the struct ip_sf_list's were already freed by:
kfree+0xe8/0x2b0 mm/slub.c:3882
ip_mc_clear_src+0x69/0x1c0 net/ipv4/igmp.c:2078

sock_release+0x8d/0x1e0 net/socket.c:597
sock_close+0x16/0x20 net/socket.c:1072
This happens because we don't hold pmc->lock in ip_mc_clear_src()
and a parallel mr_ifc_timer timer could jump in and access them.
The RCU lock is there but it is merely for pmc itself, this
spinlock could actually ensure we don't access them in parallel.
Thanks to Eric and Long for discussion on this bug.

There are many situations where generic HID driver provides some basic level
of support for certain device, but later this support (usually by implementing
vendor-specific extensions of HID protocol) is extended and the support moved
over to a separate (usually per-vendor) specific driver.
This might bring a rather unpleasant suprise for users, as all of a sudden
there is a new config option they have to enable in order to get any support
for their device whatsoever, although previous kernel versions provided basic
support through the generic driver. Which is rightfully seen as a regression.
Fix this by including the entry for a particular device in
hid_have_special_driver[] iff the specific config option has been specified,
and let generic driver handle the device otherwise.
Also make the behavior of hid_scan_report() (where the same decision is being
taken on a per-report level) consistent.
While at it, reshuffle the hid_have_special_driver[] a bit to restore the
alphabetical ordering (first order by config option, and within those
sections order by VID).
This is considered a short-term solution, before generic way of giving
precedence to special drivers and falling back to generic driver is
figured out.
While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for
spotting this (and for discovering a few issues in the conversion).

mac80211 allows to modify the SMPS state of an AP both,
when it is started, and after it has been started. Such a
change will trigger an action frame to all the peers that
are currently connected, and will be remembered so that
new peers will get notified as soon as they connect (since
the SMPS setting in the beacon may not be the right one).
This means that we need to remember the SMPS state
currently requested as well as the SMPS state that was
configured initially (and advertised in the beacon).
The former is bss->req_smps and the latter is
sdata->smps_mode.
Initially, the AP interface could only be started with
SMPS_OFF, which means that sdata->smps_mode was SMPS_OFF
always. Later, a nl80211 API was added to be able to start
an AP with a different AP mode. That code forgot to update
bss->req_smps and because of that, if the AP interface was
started with SMPS_DYNAMIC, we had:
sdata->smps_mode = SMPS_DYNAMIC
bss->req_smps = SMPS_OFF
That configuration made mac80211 think it needs to fire off
an action frame to any new station connecting to the AP in
order to let it know that the actual SMPS configuration is
SMPS_OFF.
Fix that by properly setting bss->req_smps in
ieee80211_start_ap.

When mac80211 changes the channel, it also calls into the driver's
bss_info_changed() callback, e.g. with BSS_CHANGED_IDLE. The driver
may, like iwlwifi does, access more data from bss_info in that case
and iwlwifi accesses the basic_rates bitmap, but if changing from a
band with more (basic) rates to one with fewer, an out-of-bounds
access of the rate array may result.
While we can't avoid having invalid data at some point in time, we
can avoid having it while we call the driver - so set up all the
data before configuring the channel, and then apply it afterwards.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195677

skl_check_plane_surface() already rotates the clipped plane source
coordinates to match the scanout direction because that's the way
the GTT mapping is set up. Thus we no longer need to rotate the
coordinates in the watermark code.
For cursors we use the non-clipped coordinates which are not rotated
appropriately, but that doesn't actually matter since cursors don't
even support 90/270 degree rotation.

Starting from commit b63a16f6cd89 ("drm/i915: Compute display surface
offset in the plane check hook for SKL+") we've already rotated the src
coordinates by 270 degrees by the time we check if a scaler is needed
or not, so we must not account for the rotation a second time.
Previously we did these steps in the opposite order and hence the
scaler check had to deal with rotation itself. The double rotation
handling causes us to enable a scaler pretty much every time 90/270
degree plane rotation is requested, leading to fuzzier fonts and whatnot.

This patch is based on a discussion generated by an earlier patch
from Tetsuo Handa:
* https://marc.info/?t=149035659300001&r=1&w=2
The double free problem involves the mnt_opts field of the
security_mnt_opts struct, selinux_parse_opts_str() frees the memory
on error, but doesn't set the field to NULL so if the caller later
attempts to call security_free_mnt_opts() we trigger the problem.
In order to play it safe we change selinux_parse_opts_str() to call
security_free_mnt_opts() on error instead of free'ing the memory
directly. This should ensure that everything is handled correctly,
regardless of what the caller may do.

The kmemleak and debug_pagealloc features both disable using huge pages for
direct mappings so they can do cpa() on page level granularity in any context.
However they only do that for 2MB pages, which means 1GB pages can still be
used if the CPU supports it, unless disabled by a boot param, which is
non-obvious. Disable also 1GB pages when disabling 2MB pages.

This adds code to save the values of three SPRs (special-purpose
registers) used by userspace to control event-based branches (EBBs),
which are essentially interrupts that get delivered directly to
userspace. These registers are loaded up with guest values when
entering the guest, and their values are saved when exiting the
guest, but we were not saving the host values and restoring them
before going back to userspace.
On POWER8 this would only affect userspace programs which explicitly
request the use of EBBs and also use the KVM_RUN ioctl, since the
only source of EBBs on POWER8 is the PMU, and there is an explicit
enable bit in the PMU registers (and those PMU registers do get
properly context-switched between host and guest). On POWER9 there
is provision for externally-generated EBBs, and these are not subject
to the control in the PMU registers.
Since these registers only affect userspace, we can save them when
we first come in from userspace and restore them before returning to
userspace, rather than saving/restoring the host values on every
guest entry/exit. Similarly, we don't need to worry about their
values on offline secondary threads since they execute in the context
of the idle task, which never executes in userspace.

If one 'drm_gem_handle_create()' fails, we leak somes handles and some
memory.
In order to fix it:
- move the 'free(bo_state)' at the end of the function so that it is also
called in the eror handling path. This has the side effect to also try
to free it if the first 'kcalloc' fails. This is harmless.
- add a new label, err_delete_handle, in order to delete already
allocated handles in error handling path
- remove the now useless 'err' label
The way the code is now written will also delete the handles if the
'copy_to_user()' call fails.

A recent commit to refactor the driver and remove the hw_disabled_flags
field accidentally introduced two regressions. First, we overwrote
pf->flags which removed various key flags including the MSI-X settings.
Additionally, it was intended that we have now two flags,
HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done,
and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere.
This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely
updates pf->flags instead of overwriting it.
Without this patch we will have many problems including disabling MSI-X
support, and we'll attempt to use HW ATR eviction on devices which do
not support it.

Hans managed to trigger a WARN very early in the boot which killed his
(Virtual) box.
The reason is that the recent rework of WARN() to use UD0 forgot to add the
fixup_bug() call to early_fixup_exception(). As a result the kernel does
not handle the WARN_ON injected UD0 exception and panics.
Add the missing fixup call, so early UD's injected by WARN() get handled.
Fixes: 9a93848fe787 ("x86/debug: Implement __WARN() using UD0")

This is an important part of the DDI initalization as well as
for changing the voltage during DisplayPort link training.

These tables are used on voltage wswing sequence initialization
on Cannonlake.
It is a complete new format now in use by the voltage swing team,
not following any other standard in use by any other platform.
Also the registers are different as well. So let's redefine
the translation table for Cannonlake.
The table is huge. So we minimized with the fields that are
different or might be different anytime soon. The common
values will be hardcoded on the voltage swing sequence.
v2: Merge the lower and the upper bits to match the spec table
and make review easier. This was possible with the good
idea for Manasi with a better way to handle it on the bit
macro definition presented on previous patch.

Although CNL follows PLL initialization more like Skylake
than Broxton we have a completely different initialization
sequence and registers used.
One big difference from SKL is that CDCLK PLL is now
exclusive (ADPLL) and for DDIs and MIPI we need to use
DFGPLLs 0, 1 or 2.
v2: Accept all Ander's suggestions and fixes:
- Registers and bits names prefix
- Group pll functions
- bits masks fixes
- remove read and modify on cfgcr1
- fix cfgcr0 setup
v3: Set SSC_ENABLE for DP.
Fix HDMI_MODE cfgcr0.
Avoid touch cfgcr0 on DP.
Add missed else on dpll_mgr definition so we use cnl one, not hsw.
v3: Centra freq should be always set to default and change bits
definitions to (1 << 1) instead of (1<<1). (by Paulo)
v4: Rebased.

One of the steps for PLL (un)initialization is to (un)map
the correspondent DDI that is actually using that PLL.
So, let's do this step following the places already stablished
and used so far, although spec put this as part of PLL
initialization sequences.
v2: Use proper prefix on bits names as suggested by Ander.
v3: Add missed "~". Without that the logic was inverted
so we were disabling interrupts.

Add support for changing the cdclk frequency on CNL. Again, quite
similar to BXT, but there are some annoying differences which means
trying to share more code might not be feasible:
* PLL ratio now lives in the PLL enable register
* pcode came from SKL, not from BXT
We support three cdclk frequencies: 168,336,528 Mhz. The first two
use the same PLL frequency, the last one uses a different one meaning
we once again may need to toggle the PLL off and on when changing
cdclk.
v2: Rebased by Rodrigo on top of Ville's cdclk rework.

* the PLL is now called CDCLK PLL, not DE PLL
* reference clock can be 24 MHz in addition to the 19.2 MHz BXT had
