Devicetree is enabled on 32bit kernels for OLPC support,
but this causes error messages:
'Failed to find cpu0 device node' that breaks bootsplash.
https://bugs.mageia.org/show_bug.cgi?id=16655#c39
https://bugs.mageia.org/show_bug.cgi?id=17010
So hide them behind debug for cleaner boot.

Subject: act_mirred: clear sender cpu before sending to tx
From: WANG Cong <xiyou.wangcong@gmail.com>
[ Upstream commit d40496a56430eac0d330378816954619899fe303 ]
Similar to commit c29390c6dfee ("xps: must clear sender_cpu before forwarding")
the skb->sender_cpu needs to be cleared when moving from Rx
Tx, otherwise kernel could crash.

complaints by the compiler when misusing the API.

Subject: af_unix: return data from multiple SKBs on recv() with MSG_PEEK flag
From: Aaron Conole <aconole@bytheb.org>
[ Upstream commit 9f389e35674f5b086edd70ed524ca0f287259725 ]
AF_UNIX sockets now return multiple skbs from recv() when MSG_PEEK flag
is set.
This is referenced in kernel bugzilla #12323 @
https://bugzilla.kernel.org/show_bug.cgi?id=12323
As described both in the BZ and lkml thread @
http://lkml.org/lkml/2008/1/8/444 calling recv() with MSG_PEEK on an
AF_UNIX socket only reads a single skb, where the desired effect is
to return as much skb data has been queued, until hitting the recv
buffer size (whichever comes first).
The modified MSG_PEEK path will now move to the next skb in the tree
and jump to the again: label, rather than following the natural loop
structure. This requires duplicating some of the loop head actions.
This was tested using the python socketpair python code attached to
the bugzilla issue.

Subject: ARM: ux500: simplify secondary CPU boot
From: Linus Walleij <linus.walleij@linaro.org>
commit c00def71efd919e8ae835a25f4f4c80a4b2d36d3 upstream.
This removes a lot of ancient cruft from the Ux500 SMP boot.
Instead of the pen grab/release, just point the ROM to
secondary_boot() and start the second CPU there, then send
the IPI.
Use our own SMP enable method. This enables us to remove the
last static mapping and get both CPUs booting properly.
Tested this and it just works.

Subject: arm64: errata: use KBUILD_CFLAGS_MODULE for erratum #843419
From: Will Deacon <will.deacon@arm.com>
commit b6dd8e0719c0d2d01429639a11b7bc2677de240c upstream.
Commit df057cc7b4fa ("arm64: errata: add module build workaround for
erratum #843419") sets CFLAGS_MODULE to ensure that the large memory
model is used by the compiler when building kernel modules.
However, CFLAGS_MODULE is an environment variable and intended to be
overridden on the command line, which appears to be the case with the
Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.

Subject: ath9k: declare required extra tx headroom
From: Felix Fietkau <nbd@openwrt.org>
commit 029cd0370241641eb70235d205aa0b90c84dce44 upstream.
ath9k inserts padding between the 802.11 header and the data area (to
align it). Since it didn't declare this extra required headroom, this
led to some nasty issues like randomly dropped packets in some setups.

Subject: bpf: fix panic in SO_GET_FILTER with native ebpf programs
From: Daniel Borkmann <daniel@iogearbox.net>
[ Upstream commit 93d08b6966cf730ea669d4d98f43627597077153 ]
When sockets have a native eBPF program attached through
setsockopt(sk, SOL_SOCKET, SO_ATTACH_BPF, ...), and then try to
dump these over getsockopt(sk, SOL_SOCKET, SO_GET_FILTER, ...),
the following panic appears:

The underlying issue is the very same as in commit b382c0865600
("sock, diag: fix panic in sock_diag_put_filterinfo"), that is,
native eBPF programs don't store an original program since this
is only needed in cBPF ones.
However, sk_get_filter() wasn't updated to test for this at the
time when eBPF could be attached. Just throw an error to the user
to indicate that eBPF cannot be dumped over this interface.
That way, it can also be known that a program _is_ attached (as
opposed to just return 0), and a different (future) method needs
to be consulted for a dump.

From: David Sterba <dsterba@suse.com>
commit 8eb934591f8bf584969454a658f629cd06e59f3a upstream.
We don't verify that all the balance filter arguments supplemented by
the flags are actually known to the kernel. Thus we let it silently pass
and do nothing.
At the moment this means only the 'limit' filter, but we're going to add
a few more soon so it's better to have that fixed. Also in older stable
kernels so that it works with newer userspace tools.

Subject: btrfs: fix use after free iterating extrefs
From: Chris Mason <clm@fb.com>
commit dc6c5fb3b514221f2e9d21ee626a9d95d3418dff upstream.
The code for btrfs inode-resolve has never worked properly for
files with enough hard links to trigger extrefs. It was trying to
get the leaf out of a path after freeing the path:
btrfs_release_path(path);
leaf = path->nodes[0];
item_size = btrfs_item_size_nr(leaf, slot);
The fix here is to use the extent buffer we cloned just a little higher
up to avoid deadlocks caused by using the leaf in the path.

From: Russell King <rmk+kernel@arm.linux.org.uk>
commit 8996eafdcbad149ac0f772fb1649fbb75c482a6a upstream.
Unlike shash algorithms, ahash drivers must implement export
and import as their descriptors may contain hardware state and
cannot be exported as is. Unfortunately some ahash drivers did
not provide them and end up causing crashes with algif_hash.
This patch adds a check to prevent these drivers from registering
ahash algorithms until they are fixed.

We need to explicitly check the AVX and AES CPU features, as we can't

Core i3 2310M passes the XSAVE feature test but does not implement
AES-NI.

Subject: drm: Fix locking for sysfs dpms file
From: Daniel Vetter <daniel.vetter@ffwll.ch>
commit 621bd0f6982badd6483acb191eb7b6226a578328 upstream.
With atomic drivers we need to make sure that (at least in general)
property reads hold the right locks. But the legacy dpms property is
special and can be read locklessly. Since userspace loves to just
randomly look at that all the time (like with "status") do that.
To make it clear that we play tricks use the READ_ONCE compiler
barrier (and also for paranoia).
Note that there's not really anything bad going on since even with the
new atomic paths we eventually end up not chasing any pointers (and
hence possibly freed memory and other fun stuff). The locking WARNING
has been added in
commit 88a48e297b3a3bac6022c03babfb038f1a886cea

drm: add atomic properties
but since drivers are converting not everyone will have seen this from
the start.
Jens reported this and submitted a patch to just grab the
mode_config.connection_mutex, but we can do a bit better.

Subject: drm/nouveau/fbcon: take runpm reference when userspace has an open fd
From: Ben Skeggs <bskeggs@redhat.com>
commit f231976c2e8964ceaa9250e57d27c35ff03825c2 upstream.
We need to do this in order to prevent accesses to the device while it's
powered down. Userspace may have an mmap of the fb, and there's no good
way (that I know of) to prevent it from touching the device otherwise.
This fixes some nasty races between runpm and plymouth on some systems,
which result in the GPU getting very upset and hanging the boot.

Subject: drm/qxl: fix framebuffer dirty rectangle tracking.
From: Gerd Hoffmann <kraxel@redhat.com>
commit 60906529bec506a4bde93f04eb5e7a9dd9c42a3b upstream.
Commit "c0fe07a drm/qxl: rewrite framebuffer support" has a bug in the
dirty rectangle tracking: Instead of ignoring an empty dirty rectangle
when adding a new dirty region the dirty region gets extended to the
upper left corner. Fix it.

From: Joe Perches <joe@perches.com>
[ Upstream commit 077cb37fcf6f00a45f375161200b5ee0cd4e937b ]
It seems that kernel memory can leak into userspace by a
kmalloc, ethtool_get_strings, then copy_to_user sequence.
Avoid this by using kcalloc to zero fill the copied buffer.

Subject: i2c: designware: Do not use parameters from ACPI on Dell Inspiron 7348
From: Mika Westerberg <mika.westerberg@linux.intel.com>
commit 56d4b8a24cef5d66f0d10ac778a520d3c2c68a48 upstream.
ACPI SSCN/FMCN methods were originally added because then the platform can
provide the most accurate HCNT/LCNT values to the driver. However, this
seems not to be true for Dell Inspiron 7348 where using these causes the
touchpad to fail in boot:
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: controller timed out
The values received from ACPI are (in fast mode):
HCNT: 72
LCNT: 160
this translates to following timings (input clock is 100MHz on Broadwell):
tHIGH: 720 ns (spec min 600 ns)
tLOW: 1600 ns (spec min 1300 ns)
Bus period: 2920 ns (assuming 300 ns tf and tr)
Bus speed: 342.5 kHz
Both tHIGH and tLOW are within the I2C specification.
The calculated values when ACPI parameters are not used are (in fast mode):
HCNT: 87
LCNT: 159
which translates to:
tHIGH: 870 ns (spec min 600 ns)
tLOW: 1590 ns (spec min 1300 ns)
Bus period 3060 ns (assuming 300 ns tf and tr)
Bus speed 326.8 kHz
These values are also within the I2C specification.
Since both ACPI and calculated values meet the I2C specification timing
requirements it is hard to say why the touchpad does not function properly
with the ACPI values except that the bus speed is higher in this case (but
still well below the max 400kHz).
Solve this by adding DMI quirk to the driver that disables using ACPI
parameters on this particulare machine.

From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 2306c704ce280c97a60d1f45333b822b40281dea ]
reqsk_timer_handler() tests if icsk_accept_queue.listen_opt
is NULL at its beginning.
By the time it calls inet_csk_reqsk_queue_drop() and
reqsk_queue_unlink(), listener might have been closed and
inet_csk_listen_stop() had called reqsk_queue_yank_acceptq()
which sets icsk_accept_queue.listen_opt to NULL
We therefore need to correctly check listen_opt being NULL
after holding syn_wait_lock for proper synchronization.

Subject: ipv6: Don't call with rt6_uncached_list_flush_dev
From: "Eric W. Biederman" <ebiederm@xmission.com>
[ Upstream commit e332bc67cf5e5e5b71a1aec9750d0791aac65183 ]
As originally written rt6_uncached_list_flush_dev makes no sense when
called with dev == NULL as it attempts to flush all uncached routes
regardless of network namespace when dev == NULL. Which is simply
incorrect behavior.
Furthermore at the point rt6_ifdown is called with dev == NULL no more
network devices exist in the network namespace so even if the code in
rt6_uncached_list_flush_dev were to attempt something sensible it
would be meaningless.
Therefore remove support in rt6_uncached_list_flush_dev for handling
network devices where dev == NULL, and only call rt6_uncached_list_flush_dev
when rt6_ifdown is called with a network device.

Subject: KVM: x86: fix RSM into 64-bit protected mode
From: Paolo Bonzini <pbonzini@redhat.com>
commit b10d92a54dac25a6152f1aa1ffc95c12908035ce upstream.
In order to get into 64-bit protected mode, you need to enable
paging while EFER.LMA=1. For this to work, CS.L must be 0.
Currently, we load the segments before CR0 and CR4, which means
that if RSM returns into 64-bit protected mode CS.L is already 1
and everything breaks.
Luckily, CS.L=0 is always the case when executing RSM, because it
is forbidden to execute RSM from 64-bit protected mode. Hence it
is enough to load CR0 and CR4 first, and only then the segments.

From: Chaotian Jing <chaotian.jing@mediatek.com>
commit 08b137d90eec51b0e90c42e123ca8ceb118d233f upstream.
Suppose that we got a data crc error, and it triggers the mmc_reset.
mmc_reset will call mmc_send_status to see if HW reset was supported.
before issue CMD13, it will do retune, and if EMMC was in HS400 mode,
it will reduce frequency to 52Mhz firstly, then results in card init
was doing at 52Mhz.
The mmc_send_status was originally only done for mmc_test, should drop
it. And, rename the "eMMC hardware reset" to "Reset test", as we would
also be able to use the test for SD-cards.

Greg reported crashes hitting the following check in __sk_backlog_rcv()
BUG_ON(!sock_flag(sk, SOCK_MEMALLOC));
The pfmemalloc bit is currently checked in sk_filter().
This works correctly for TCP, because sk_filter() is ran in
tcp_v[46]_rcv() before hitting the prequeue or backlog checks.
For UDP or other protocols, this does not work, because the sk_filter()
is ran from sock_queue_rcv_skb(), which might be called _after_ backlog
queuing if socket is owned by user by the time packet is processed by
softirq handler.

From: Ivan Mikhaylov <ivan@ru.ibm.com>
[ Upstream commit 661dfc65f7981481ba2e31aaa702371e82336e56 ]
The size of the MAC register dump used to be the size specified by the
reg property in the device tree. Userland has no good way of finding
out that size, and it was not specified consistently for each MAC type,
so ethtool would end up printing junk at the end of the register dump
if the device tree didn't match the size it assumed.
Using the new version numbers indicates unambiguously that the size of
the MAC register dump is dependent only on the MAC type.

Subject: net/unix: fix logic about sk_peek_offset
From: Andrey Vagin <avagin@openvz.org>
[ Upstream commit e9193d60d363e4dff75ff6d43a48f22be26d59c7 ]
Now send with MSG_PEEK can return data from multiple SKBs.
Unfortunately we take into account the peek offset for each skb,
that is wrong. We need to apply the peek offset only once.
In addition, the peek offset should be used only if MSG_PEEK is set.

Subject: netlink: Trim skb to alloc size to avoid MSG_TRUNC
From: "Arad, Ronen" <ronen.arad@intel.com>
[ Upstream commit db65a3aaf29ecce2e34271d52e8d2336b97bd9fe ]
netlink_dump() allocates skb based on the calculated min_dump_alloc or
a per socket max_recvmsg_len.
min_alloc_size is maximum space required for any single netdev
attributes as calculated by rtnl_calcit().
max_recvmsg_len tracks the user provided buffer to netlink_recvmsg.
It is capped at 16KiB.
The intention is to avoid small allocations and to minimize the number
of calls required to obtain dump information for all net devices.
netlink_dump packs as many small messages as could fit within an skb
that was sized for the largest single netdev information. The actual
space available within an skb is larger than what is requested. It could
be much larger and up to near 2x with align to next power of 2 approach.
Allowing netlink_dump to use all the space available within the
allocated skb increases the buffer size a user has to provide to avoid
truncaion (i.e. MSG_TRUNG flag set).
It was observed that with many VLANs configured on at least one netdev,
a larger buffer of near 64KiB was necessary to avoid "Message truncated"
error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when
min_alloc_size was only little over 32KiB.
This patch trims skb to allocated size in order to allow the user to
avoid truncation with more reasonable buffer size.

From: Christoph Hellwig <hch@lst.de>
commit 8c3ad9cb7343dc5f61b8cf3cdbe1016c5e7c2c8b upstream.
Recent Linux clients have started to send GETLAYOUT requests with
minlength less than blocksize.
Servers aren't really allowed to impose this kind of restriction on
layouts; see RFC 5661 section 18.43.3 for details.
This has been observed to cause indefinite hangs on fsx runs on some
clients.

When openvswitch tries allocate memory from offline numa node 0:
stats = kmem_cache_alloc_node(flow_stats_cache, GFP_KERNEL | __GFP_ZERO, 0)
It catches VM_BUG_ON(nid < 0 || nid >= MAX_NUMNODES || !node_online(nid))
[ replaced with VM_WARN_ON(!node_online(nid)) recently ] in linux/gfp.h

[ Upstream commit e6740165b8f7f06d8caee0fceab3fb9d790a6fed ]
Since commit 2b018d57ff18 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release"),
pppoe_release() calls dev_put(po->pppoe_dev) if sk is in the
PPPOX_ZOMBIE state. But pppoe_flush_dev() can set sk->sk_state to
PPPOX_ZOMBIE _and_ reset po->pppoe_dev to NULL. This leads to the
following oops:

Subject: skbuff: Fix skb checksum flag on skb pull
From: Pravin B Shelar <pshelar@nicira.com>
[ Upstream commit 6ae459bdaaeebc632b16e54dcbabb490c6931d61 ]
VXLAN device can receive skb with checksum partial. But the checksum
offset could be in outer header which is pulled on receive. This results
in negative checksum offset for the skb. Such skb can cause the assert
failure in skb_checksum_help(). Following patch fixes the bug by setting
checksum-none while pulling outer header.
Following is the kernel panic msg from old kernel hitting the bug.

skb by comparing pull length to checksum offset. But it does
not work for all cases since checksum-offset depends on
updates to skb->data.
Following patch fixes it by validating checksum start offset
after skb-data pointer is updated. Negative value of checksum
offset start means there is no need to checksum.
Fixes: 6ae459bda ("skbuff: Fix skb checksum flag on skb pull")

Subject: tipc: move fragment importance field to new header position
From: Jon Paul Maloy <jon.maloy@ericsson.com>
[ Upstream commit dde4b5ae65de659b9ec64bafdde0430459fcb495 ]
In commit e3eea1eb47a ("tipc: clean up handling of message priorities")
we introduced a field in the packet header for keeping track of the
priority of fragments, since this value is not present in the specified
protocol header. Since the value so far only is used at the transmitting
end of the link, we have not yet officially defined it as part of the
protocol.
Unfortunately, the field we use for keeping this value, bits 13-15 in
in word 5, has turned out to be a poor choice; it is already used by the
broadcast protocol for carrying the 'network id' field of the sending
node. Since packet fragments also need to be transported across the
broadcast protocol, the risk of conflict is obvious, and we see this
happen when we use network identities larger than 2^13-1. This has
escaped our testing because we have so far only been using small network
id values.
We now move this field to bits 0-2 in word 9, a field that is guaranteed
to be unused by all involved protocols.

Subject: workqueue: make sure delayed work run in local cpu
From: Shaohua Li <shli@fb.com>
commit 874bbfe600a660cba9c776b3957b1ce393151b76 upstream.
My system keeps crashing with below message. vmstat_update() schedules a delayed
work in current cpu and expects the work runs in the cpu.
schedule_delayed_work() is expected to make delayed work run in local cpu. The
problem is timer can be migrated with NO_HZ. __queue_work() queues work in
timer handler, which could run in a different cpu other than where the delayed
work is scheduled. The end result is the delayed work runs in different cpu.
The patch makes __queue_delayed_work records local cpu earlier. Where the timer
runs doesn't change where the work runs with the change.
