Subject: [PATCH] OOM detection regressions since 4.7
Hi,
there have been multiple reports [1][2][3][4][5] about pre-mature OOM
killer invocations since 4.7 which contains oom detection rework. All of
them were for order-2 (kernel stack) alloaction requests failing because
of a high fragmentation and compaction failing to make any forward
progress. While investigating this we have found out that the compaction
just gives up too early. Vlastimil has been working on compaction
improvement for quite some time and his series [6] is already sitting
in mmotm tree. This already helps a lot because it drops some heuristics
which are more aimed at lower latencies for high orders rather than
reliability. Joonsoo has then identified further problem with too many
blocks being marked as unmovable [7] and Vlastimil has prepared a patch
on top of his series [8] which is also in the mmotm tree now.
That being said, the regression is real and should be fixed for 4.7
stable users. [6][8] was reported to help and ooms are no longer
reproducible. I know we are quite late (rc3) in 4.8 but I would vote
for mergeing those patches and have them in 4.8. For 4.7 I would go
with a partial revert of the detection rework for high order requests
(see patch below). This patch is really trivial. If those compaction
improvements are just too large for 4.8 then we can use the same patch
as for 4.7 stable for now and revert it in 4.9 after compaction changes
are merged.
Thoughts?

Subject: [PATCH] SUNRPC: Fix infinite looping in
rpc_clnt_iterate_for_each_xprt
If there were less than 2 entries in the multipath list, then
xprt_iter_next_entry_multiple() would never advance beyond the
first entry, which is correct for round robin behaviour, but not
for the list iteration.
The end result would be infinite looping in rpc_clnt_iterate_for_each_xprt()
as we would never see the xprt == NULL condition fulfilled.

__cgroups_proc_write(). I've recently run into a scenario with lots

This thread is waiting on the reader of cgroup_threadgroup_rwsem to

reclaim after fork. There are times the reader also ends up waiting on
oom_lock as well.

In the meanwhile, all processes exiting/forking are blocked almost
stalling the system.
This patch moves the threadgroup_change_begin from before
cgroup_fork() to just before cgroup_canfork(). There is no nee to
worry about threadgroup changes till the task is actually added to the
threadgroup. This avoids having to call reclaim with
cgroup_threadgroup_rwsem held.

Subject: [PATCH 01/17] drm/i915: Reorganize WM structs/unions in CRTC state
Reorganize the nested structures and unions we have for pipe watermark
data in intel_crtc_state so that platform-specific data can be added in
a more sensible manner (and save a bit of memory at the same time).
The change basically changes the organization from:
union {
struct intel_pipe_wm ilk;
struct intel_pipe_wm skl;
} optimal;
struct intel_pipe_wm intermediate /* ILK-only */
to
union {
struct {
struct intel_pipe_wm intermediate;
struct intel_pipe_wm optimal;
} ilk;
struct {
struct intel_pipe_wm optimal;
} skl;
}
There should be no functional change here, but it will allow us to add
more platform-specific fields going forward (and more easily extend to
other platform types like VLV).
While we're at it, let's move the entire watermark substructure out to
its own structure definition to make the code slightly more readable.

From 7ea59202db8d20806d9ae552acd1875c3a978bcc Mon Sep 17 00:00:00 2001

Subject: [PATCH] selinux: Only apply bounds checking to source types
The current bounds checking of both source and target types
requires allowing any domain that has access to the child
domain to also have the same permissions to the parent, which
is undesirable. Drop the target bounds checking.
KaiGai Kohei originally removed all use of target bounds in
commit 7d52a155e38d ("selinux: remove dead code in
type_attribute_bounds_av()") but this was reverted in
commit 2ae3ba39389b ("selinux: libsepol: remove dead code in
check_avtab_hierarchy_callback()") because it would have
required explicitly allowing the parent any permissions
to the child that the child is allowed to itself.
This change in contrast retains the logic for the case where both
source and target types are bounded, thereby allowing access
if the parent of the source is allowed the corresponding
permissions to the parent of the target. Further, this change
reworks the logic such that we only perform a single computation
for each case and there is no ambiguity as to how to resolve
a bounds violation.
Under the new logic, if the source type and target types are both
bounded, then the parent of the source type must be allowed the same
permissions to the parent of the target type. If only the source
type is bounded, then the parent of the source type must be allowed
the same permissions to the target type.
Examples of the new logic and comparisons with the old logic:
1. If we have:
typebounds A B;
then:
allow B self:process <permissions>;
will satisfy the bounds constraint iff:
allow A self:process <permissions>;
is also allowed in policy.
Under the old logic, the allow rule on B satisfies the
bounds constraint if any of the following three are allowed:
allow A B:process <permissions>; or
allow B A:process <permissions>; or
allow A self:process <permissions>;
However, either of the first two ultimately require the third to
satisfy the bounds constraint under the old logic, and therefore
this degenerates to the same result (but is more efficient - we only
need to perform one compute_av call).
2. If we have:
typebounds A B;
typebounds A_exec B_exec;
then:
allow B B_exec:file <permissions>;
will satisfy the bounds constraint iff:
allow A A_exec:file <permissions>;
is also allowed in policy.
This is essentially the same as #1; it is merely included as
an example of dealing with object types related to a bounded domain
in a manner that satisfies the bounds relationship. Note that
this approach is preferable to leaving B_exec unbounded and having:
allow A B_exec:file <permissions>;
in policy because that would allow B's entrypoints to be used to
enter A. Similarly for _tmp or other related types.
3. If we have:
typebounds A B;
and an unbounded type T, then:
allow B T:file <permissions>;
will satisfy the bounds constraint iff:
allow A T:file <permissions>;
is allowed in policy.
The old logic would have been identical for this example.
4. If we have:
typebounds A B;
and an unbounded domain D, then:
allow D B:unix_stream_socket <permissions>;
is not subject to any bounds constraints under the new logic
because D is not bounded. This is desirable so that we can
allow a domain to e.g. connectto a child domain without having
to allow it to do the same to its parent.
The old logic would have required:
allow D A:unix_stream_socket <permissions>;
to also be allowed in policy.

Subject: [PATCH] udp: fix poll() issue with zero sized packets
Laura tracked poll() [and friends] regression caused by commit
e6afc8ace6dd ("udp: remove headers from UDP packets before queueing")
udp_poll() needs to know if there is a valid packet in receive queue,
even if its payload length is 0.
Change first_packet_length() to return an signed int, and use -1
as the indication of an empty queue.
Fixes: e6afc8ace6dd ("udp: remove headers from UDP packets before queueing")

drm/i915: Rename s/skl_compute_pipe_wm/skl_build_pipe_wm/
When we added atomic watermarks, we added a new display vfunc
'compute_pipe_wm' that is used to compute any pipe-specific watermark
information that we can at atomic check time. This was a somewhat poor
naming choice since we already had a 'skl_compute_pipe_wm' function that
doesn't quite fit this model --- the existing SKL function is something
that gets used at atomic commit time, after the DDB allocation has been
determined. Let's rename the existing SKL function to avoid confusion.

drm/i915/gen9: Cache plane data rates in CRTC state
This will be important when we start calculating CRTC data rates for
in-flight CRTC states since it will allow us to calculate the total data
rate without needing to grab the plane state for any planes that aren't
updated by the transaction.

drm/i915/gen9: Allow calculation of data rate for in-flight state (v2)
Our skl_get_total_relative_data_rate() function gets passed a crtc state
object to calculate the data rate for, but it currently always looks
up the committed plane states that correspond to that CRTC. Let's
check whether the CRTC state is an in-flight state (meaning
cstate->state is non-NULL) and if so, use the corresponding in-flight
plane states.
We'll soon be using this function exclusively for in-flight states; at
that time we'll be able to simplify the function a bit, but for now we
allow it to be used in either mode.
v2:
- Rebase on top of changes to cache plane data rates.

drm/i915/gen9: Store plane minimum blocks in CRTC wm state (v2)
This will eventually allow us to re-use old values without
re-calculating them for unchanged planes (which also helps us avoid
re-grabbing extra plane states).
v2:
- Drop unnecessary memset's; they were meant for a later patch (which
got reworked anyway to not need them, but were mis-rebased into this
one. (Maarten)

drm/i915: Track whether an atomic transaction changes the active CRTC's
For the purposes of DDB re-allocation we need to know whether a
transaction changes the list of CRTC's that are active. While
state->modeset could be used for this purpose, that would be slightly
too aggressive since it would lead us to re-allocate the DDB when a
CRTC's mode changes, but not its final active state.

drm/i915/gen9: Allow skl_allocate_pipe_ddb() to operate on in-flight state (v3)
We eventually want to calculate watermark values at atomic 'check' time
instead of atomic 'commit' time so that any requested configurations
that result in impossible watermark requirements are properly rejected.
The first step along this path is to allocate the DDB at atomic 'check'
time. As we perform this transition, allow the main allocation function
to operate successfully on either an in-flight state or an
already-commited state. Once we complete the transition in a future
patch, we'll come back and remove the unnecessary logic for the
already-committed case.
v2: Rebase/refactor; we should no longer need to grab extra plane states
while allocating the DDB since we can pull cached data rates and
minimum block counts from the CRTC state for any planes that aren't
being modified by this transaction.
v3:
- Simplify memsets to clear DDB plane entries. (Maarten)
- Drop a redundant memset of plane[pipe][PLANE_CURSOR] that was added
by an earlier Coccinelle patch. (Maarten)
- Assign *num_active at the top of skl_ddb_get_pipe_allocation_limits()
so that no code paths return without setting it. (kbuild robot)

Subject: [PATCH 08/17] drm/i915: Add distrust_bios_wm flag to dev_priv (v2)
SKL-style platforms can't fully trust the watermark/DDB settings
programmed by the BIOS and need to do extra sanitization on their first
atomic update. Add a flag to dev_priv that is set during hardware
readout and cleared at the end of the first commit.
Note that for the somewhat common case where everything is turned off
when the driver starts up, we don't need to bother with a recompute...we
know exactly what the DDB should be (all zero's) so just setup the DDB
directly in that case.
v2:
- Move clearing of distrust_bios_wm up below the swap_state call since
it's a more natural / self-explanatory location. (Maarten)
- Use dev_priv->active_crtcs to test whether any CRTC's are turned on
during HW WM readout rather than trying to count the active CRTC's
again ourselves. (Maarten)

Subject: [PATCH 09/17] drm/i915/gen9: Compute DDB allocation at atomic check
time (v4)
Calculate the DDB blocks needed to satisfy the current atomic
transaction at atomic check time. This is a prerequisite to calculating
SKL watermarks during the 'check' phase and rejecting any configurations
that we can't find valid watermarks for.
Due to the nature of DDB allocation, it's possible for the addition of a
new CRTC to make the watermark configuration already in use on another,
unchanged CRTC become invalid. A change in which CRTC's are active
triggers a recompute of the entire DDB, which unfortunately means we
need to disallow any other atomic commits from racing with such an
update. If the active CRTC's change, we need to grab the lock on all
CRTC's and run all CRTC's through their 'check' handler to recompute and
re-check their per-CRTC DDB allocations.
Note that with this patch we only compute the DDB allocation but we
don't actually use the computed values during watermark programming yet.
For ease of review/testing/bisecting, we still recompute the DDB at
watermark programming time and just WARN() if it doesn't match the
precomputed values. A future patch will switch over to using the
precomputed values once we're sure they're being properly computed.
Another clarifying note: DDB allocation itself shouldn't ever fail with
the algorithm we use today (i.e., we have enough DDB blocks on BXT to
support the minimum needs of the worst-case scenario of every pipe/plane
enabled at full size). However the watermarks calculations based on the
DDB may fail and we'll be moving those to the atomic check as well in
future patches.
v2:
- Skip DDB calculations in the rare case where our transaction doesn't
actually touch any CRTC's at all. Assuming at least one CRTC state
is present in our transaction, then it means we can't race with any
transactions that would update dev_priv->active_crtcs (which requires
_all_ CRTC locks).
v3:
- Also calculate DDB during initial hw readout, to prevent using
incorrect bios values. (Maarten)
v4:
- Use new distrust_bios_wm flag instead of skip_initial_wm (which was
never actually set).
- Set intel_state->active_pipe_changes instead of just realloc_pipes

Subject: [PATCH 10/17] drm/i915/gen9: Drop re-allocation of DDB at atomic
commit (v2)
Now that we're properly pre-allocating the DDB during the atomic check
phase and we trust that the allocation is appropriate, let's actually
use the allocation computed and not duplicate that work during the
commit phase.
v2:
- Significant rebasing now that we can use cached data rates and
minimum block allocations to avoid grabbing additional plane states.

drm/i915/gen9: Calculate plane WM's from state
In a future patch we'll want to calculate plane watermarks for in-flight
atomic state rather than the already-committed state.

drm/i915/gen9: Allow watermark calculation on in-flight atomic state (v3)
In an upcoming patch we'll move this calculation to the atomic 'check'
phase so that the display update can be rejected early if no valid
watermark programming is possible.
v2:
- Drop intel_pstate_for_cstate_plane() helper and add note about how
the code needs to evolve in the future if we start allowing more than
one pending commit against a CRTC. (Maarten)
v3:
- Only have skl_compute_wm_level calculate watermarks for enabled
planes; we can just set the other planes on a CRTC to disabled
without having to look at the plane state. This is important because
despite our CRTC lock we can still have racing commits that modify
a disabled plane's property without turning it on. (Maarten)

drm/i915/gen9: Propagate watermark calculation failures up the call chain
Once we move watermark calculation to the atomic check phase, we'll want
to start rejecting display configurations that exceed out watermark
limits. At the moment we just assume that there's always a valid set of
watermarks, even though this may not actually be true. Let's prepare by
passing return codes up through the call stack in preparation.

Subject: [PATCH 15/17] drm/i915/gen9: Calculate watermarks during atomic
'check' (v2)
Moving watermark calculation into the check phase will allow us to to
reject display configurations for which there are no valid watermark
values before we start trying to program the hardware (although those
tests will come in a subsequent patch).
Another advantage of moving this calculation to the check phase is that
we can calculate the watermarks in a single shot as part of the atomic
transaction. The watermark interfaces we inherited from our legacy
modesetting days are a bit broken in the atomic design because they use
per-crtc entry points but actually re-calculate and re-program something
that is really more of a global state. That worked okay in the legacy
modesetting world because operations only ever updated a single CRTC at
a time. However in the atomic world, a transaction can involve multiple
CRTC's, which means we wind up computing and programming the watermarks
NxN times (where N is the number of CRTC's involved). With this patch
we eliminate the redundant re-calculation of watermark data for atomic
states (which was the cause of the WARN_ON(!wm_changed) problems that
have plagued us for a while).
We still need to work on the 'commit' side of watermark handling so that
we aren't doing redundant NxN programming of watermarks, but that's
content for future patches.
v2:
- Bail out of skl_write_wm_values() if the CRTC isn't active. Now that
we set dirty_pipes to ~0 if the active pipes change (because
we need to deal with DDB changes), we can now wind up here for
disabled pipes, whereas we couldn't before.

drm/i915/gen9: Reject display updates that exceed wm limitations (v2)
If we can't find any valid level 0 watermark values for the requested
atomic transaction, reject the configuration before we try to start
programming the hardware.
v2:
- Add extra debugging output when we reject level 0 watermarks so that
we can more easily debug how/why they were rejected.

Subject: [PATCH 17/17] drm/i915: Remove wm_config from
dev_priv/intel_atomic_state
We calculate the watermark config into intel_atomic_state and then save
it into dev_priv, but never actually use it from there. This is
left-over from some early ILK-style watermark programming designs that
got changed over time.

From fa00c437eef8dc2e7b25f8cd868cfa405fcc2bb3 Mon Sep 17 00:00:00 2001
From: Dave Carroll <david.carroll@microsemi.com>
Date: Fri, 5 Aug 2016 13:44:10 -0600
Subject: [PATCH] aacraid: Check size values after double-fetch from user
In aacraid's ioctl_send_fib() we do two fetches from userspace, one the
get the fib header's size and one for the fib itself. Later we use the
size field from the second fetch to further process the fib. If for some
reason the size from the second fetch is different than from the first
fix, we may encounter an out-of- bounds access in aac_fib_send(). We
also check the sender size to insure it is not out of bounds. This was
reported in https://bugzilla.kernel.org/show_bug.cgi?id=116751 and was
assigned CVE-2016-6480.

Subject: [PATCH] arm: i.MX6 Utilite device dtb
From: Christopher Spinrath <christopher.spinrath@xxxxxxxxxxxxxx>
The CompuLab Utilite Pro is a miniature fanless desktop pc based on
the i.MX6 Quad powered cm-fx6 module. It features two serial ports,
USB OTG, 4x USB, analog audio and S/PDIF, 2x Gb Ethernet, HDMI and
DVI ports, an on-board 32GB SSD, a mmc slot, and on-board wifi/bt.
Add initial support for it including USB, Ethernet (both ports), sata
and HDMI support.

2.8.2
From: Christopher Spinrath <christopher.spinrath@xxxxxxxxxxxxxx>
The cm-fx6 module has an on-board spi-flash chip for its firmware, an
eeprom (containing e.g. the mac address of the on-board Ethernet),
a sata port, a pcie controller, an USB hub, and an USB otg port.
Enable support for them. In addition, enable syscon poweroff support.

From: Peter Robinson <pbrobinson@gmail.com>
Date: Tue, 5 Jul 2016 23:49:39 +0100
Subject: [PATCH 1/4] Some platforms may not be fully compliant with generic
set of PCI config accessors. For these cases we implement the way to
overwrite accessors set. Algorithm traverses available quirk list, matches
against <oem_id, oem_table_id, domain, bus number> tuple and returns
corresponding PCI config ops. oem_id and oem_table_id come from MCFG table
standard header. All quirks can be defined using DECLARE_ACPI_MCFG_FIXUP()
macro and kept self contained. Example:
/* Custom PCI config ops */
static struct pci_generic_ecam_ops foo_pci_ops = {
.bus_shift = 24,
.pci_ops = {
.map_bus = pci_ecam_map_bus,
.read = foo_ecam_config_read,
.write = foo_ecam_config_write,
}
};
DECLARE_ACPI_MCFG_FIXUP(&foo_pci_ops, <oem_id_str>, <oem_table_id>, <domain_nr>, <bus_nr>);

Subject: [PATCH 2/4] pci_generic_ecam_ops is used by default. Since there are
platforms which have non-compliant ECAM space we need to overwrite these
accessors prior to PCI buses enumeration. In order to do that we call
pci_mcfg_get_ops to retrieve pci_ecam_ops structure so that we can use proper
PCI config space accessors and bus_shift.
pci_generic_ecam_ops is still used for platforms free from quirks.

Subject: [PATCH 3/4] The ECAM quirk matching criteria per the discussion on
https://lkml.org/lkml/2016/6/13/944 includes: OEM ID, OEM Table ID and OEM
Revision. So this patch adds OEM Table ID into the check to match platform
specific ECAM quirks as well.
This patch also improve strncmp check using strlen and
min_t to ignore the padding spaces in OEM ID and OEM
Table ID.

Subject: [PATCH 1/2] ARM: bcm2835: dt: Add the ethernet to the device trees
The hub and the ethernet in its port 1 are hardwired on the board.
Compared to the adapters that can be plugged into the USB ports, this
one has no serial EEPROM to store its MAC. Nevertheless, the Raspberry Pi
has the MAC address for this adapter in its ROM, accessible from its
firmware.
U-Boot can read out the address and set the local-mac-address property of the
node with "ethernet" alias. Let's add the node so that U-Boot can do its
business.
Model B rev2 and Model B+ entries were verified by me, the hierarchy and
pid/vid pair for the Version 2 was provided by Peter Chen. Original
Model B is a blind shot, though very likely correct.

From 74f829a6e44fe217b6161f8935524fc807be0648 Mon Sep 17 00:00:00 2001

Date: Sat, 9 Jul 2016 11:01:20 +0100
Subject: [PATCH] drm/i915: Acquire audio powerwell for HD-Audio registers
On Haswell/Broadwell, the HD-Audio block is inside the HDMI/display
power well and so the sna-hda audio codec acquires the display power
well while it is operational. However, Skylake separates the powerwells
again, but yet we still need the audio powerwell to setup the registers.
(But then the hardware uses those registers even while powered off???)
v2: Grab both rpm wakelock and audio wakelock
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96214
Fixes: 03b135cebc47 "ALSA: hda - remove dependency on i915 power well for SKL")

Subject: [PATCH] input: silence i8042 noise
Don't print an error message just because there's no i8042 chip.
Some systems, such as EFI-based Apple systems, won't necessarily have an
i8042 to initialize. We shouldn't be printing an error message in this
case, since not detecting the chip is the correct behavior.
Bugzilla: N/A
Upstream-status: Fedora mustard

Subject: [PATCH] pinctrl: pinctrl-single must be initialized early.
When using pinctrl-single to handle i2c initialization, it has
to be done early. Whether this is the best way to do so, is an
exercise left to the reader.

Subject: Partly revert "[media] rc-core: allow calling rc_open with device not initialized"
This partly reverts commit 078600f514a12fd763ac84c86af68ef5b5267563.
Due to the relocation of input_register_device() call, holding down a
button on an IR remote no longer resulted in repeated key down events.

Subject: rds: fix an infoleak in rds_inc_info_copy
The last field "flags" of object "minfo" is not initialized.
Copying this object out may leak kernel stack data.
Assign 0 to it to avoid leak.
