Currently the vmstat updater is not deferrable as a result of commit
ba4877b9ca51 ("vmstat: do not use deferrable delayed work for
vmstat_update"). This in turn can cause multiple interruptions of the
applications because the vmstat updater may run at
Make vmstate_update deferrable again and provide a function that folds
the differentials when the processor is going to idle mode thus
addressing the issue of the above commit in a clean way.
Note that the shepherd thread will continue scanning the differentials
from another processor and will reenable the vmstat workers if it
detects any changes.
Fixes: ba4877b9ca51 ("vmstat: do not use deferrable delayed work for vmstat_update")

[ Upstream commit 2baa753c276f27f8e844637561ad597867aa6fb6 ]
It is not allowed to free the memory of an object which is part of a list
which is protected by rcu-read-side-critical sections without making sure
that no other context is accessing the object anymore. This usually happens
by removing the references to this object and then waiting until the rcu
grace period is over and no one (allowedly) accesses it anymore.
But the _now functions ignore this completely. They free the object
directly even when a different context still tries to access it. This has
to be avoided and thus these functions must be removed and all functions
have to use batadv_neigh_node_free_ref.

From: Dan Streetman <dan.streetman@canonical.com>
[ Upstream commit a8a572a6b5f2a79280d6e302cb3c1cb1fbaeb3e8 ]
Remove the dst_entries_init/destroy calls for xfrm4 and xfrm6 dst_ops
templates; their dst_entries counters will never be used. Move the
xfrm dst_ops initialization from the common xfrm/xfrm_policy.c to
xfrm4/xfrm4_policy.c and xfrm6/xfrm6_policy.c, and call dst_entries_init
and dst_entries_destroy for each net namespace.
The ipv4 and ipv6 xfrms each create dst_ops template, and perform
dst_entries_init on the templates. The template values are copied to each
net namespace's xfrm.xfrm*_dst_ops. The problem there is the dst_ops
pcpuc_entries field is a percpu counter and cannot be used correctly by
simply copying it to another object.
The result of this is a very subtle bug; changes to the dst entries
counter from one net namespace may sometimes get applied to a different
net namespace dst entries counter. This is because of how the percpu
counter works; it has a main count field as well as a pointer to the
percpu variables. Each net namespace maintains its own main count
variable, but all point to one set of percpu variables. When any net
namespace happens to change one of the percpu variables to outside its
small batch range, its count is moved to the net namespace's main count
variable. So with multiple net namespaces operating concurrently, the
dst_ops entries counter can stray from the actual value that it should
be; if counts are consistently moved from one net namespace to another
(which my testing showed is likely), then one net namespace winds up
with a negative dst_ops count while another winds up with a continually
increasing count, eventually reaching its gc_thresh limit, which causes
all new traffic on the net namespace to fail with -ENOBUFS.

commit 6611d8d76132f86faa501de9451a89bf23fb2371 upstream.
A spare array holding mem cgroup threshold events is kept around to make
sure we can always safely deregister an event and have an array to store
the new set of events in.
In the scenario where we're going from 1 to 0 registered events, the
pointer to the primary array containing 1 event is copied to the spare
slot, and then the spare slot is freed because no events are left.
However, it is freed before calling synchronize_rcu(), which means
readers may still be accessing threshold->primary after it is freed.
Fixed by only freeing after synchronize_rcu().

[ Upstream commit c6894dec8ea9ae05747124dce98b3b5c2e69b168 ]
After promisc mode management was introduced a bridge device could do
dev_set_promiscuity from its ndo_change_rx_flags() callback which in
turn can be called after the bridge's addr_list_lock has been taken
(e.g. by dev_uc_add). This causes a false positive lockdep splat because
the port interfaces' addr_list_lock is taken when br_manage_promisc()
runs after the bridge's addr list lock was already taken.
To remove the false positive introduce a custom bridge addr_list_lock
class and set it on bridge init.
A simple way to reproduce this is with the following:
$ brctl addbr br0
$ ip l add l br0 br0.100 type vlan id 100
$ ip l set br0 up
$ ip l set br0.100 up
$ echo 1 > /sys/class/net/br0/bridge/vlan_filtering
$ brctl addif br0 eth0

Originally that parameter was always reset to num_online_cpus during
module initialisation, which renders it useless.
The fix is to only set max_queues to num_online_cpus when user has not
provided a value.

Commit 1f718f0f4f97 ("bonding: populate neighbour's private on enslave")
undoes the fix provided by commit c2edacf80e15 ("bonding / ipv6: no addrconf
for slaves separately from master") by effectively setting the slave flag
after the slave has been opened. If the slave comes up quickly enough, it
will go through the IPv6 addrconf before the slave flag has been set and
will get a link local IPv6 address.
In order to ensure that addrconf knows to ignore the slave devices on state
change, set IFF_SLAVE before dev_open() during bonding enslavement.

From: Russell King <rmk+kernel@arm.linux.org.uk>
commit d9812780a020bcec44565b5950b2a8b31afb5545 upstream.
The SD card specification allows cards to error out a SWITCH command
where the requested function in a group is not supported. The spec
provides for a set of capabilities which indicate which functions are
supported.
In the case of the power limit, requesting an unsupported power level
via the SWITCH command fails, resulting in the power level remaining at
the power-on default of 0.72W, even though the host and card may support
higher powers levels.
This has been seen with SanDisk 8GB cards, which support the default
0.72W and 1.44W (200mA and 400mA) in combination with an iMX6 host,
supporting up to 2.88W (800mA). This currently causes us to try to set
a power limit function value of '3' (2.88W) which the card errors out
on, and thereby causes the power level to remain at 0.72W rather than
the desired 1.44W.
Arrange to limit the selected current limit by the capabilities reported
by the card to avoid the SWITCH command failing. Select the highest
current limit that the host and card combination support.

From: Nicolas Boichat <drinkcat@chromium.org>
commit 9586495dc3011a80602329094e746dbce16cb1f1 upstream.
This reverts one hunk of
commit ef44a1ec6eee ("ALSA: sound/core: use memdup_user()"), which
replaced a number of kmalloc followed by memcpy with memdup calls.
In this case, we are copying from a struct snd_seq_port_info32 to a
struct snd_seq_port_info, but the latter is 4 bytes longer than the
32-bit version, so we need to separate kmalloc and copy calls.
Fixes: ef44a1ec6eee ('ALSA: sound/core: use memdup_user()')

[ Upstream commit 60a6531bfe49555581ccd65f66a350cc5693fcde ]
We can't be within an RCU read-side critical section when deleting
VLANs, as underlying drivers might sleep during the hardware operation.
Therefore, replace the RCU critical section with a mutex. This is
consistent with team_vlan_rx_add_vid.

commit 32abc2ede536aae52978d6c0a8944eb1df14f460 upstream.
When a long value is read on 32 bit machines for 64 bit output, the
parsing needs to change "%lu" into "%llu", as the value is read
natively.
Unfortunately, if "%llu" is already there, the code will add another "l"
to it and fail to parse it properly.

[ Upstream commit 7aaed57c5c2890634cfadf725173c7c68ea4cb4f ]
Ivaylo Dimitrov reported a regression caused by commit 7866a621043f
("dev: add per net_device packet type chains").
skb->dev becomes NULL and we crash in __netif_receive_skb_core().
Before above commit, different kind of bugs or corruptions could happen
without major crash.
But the root cause is that phonet_rcv() can queue skb without checking
if skb is shared or not.
Many thanks to Ivaylo Dimitrov for his help, diagnosis and tests.

From: Sven Eckelmann <sven@narfation.org>
[ Upstream commit b4d922cfc9c08318eeb77d53b7633740e6b0efb0 ]
It is not allowed to free the memory of an object which is part of a list
which is protected by rcu-read-side-critical sections without making sure
that no other context is accessing the object anymore. This usually happens
by removing the references to this object and then waiting until the rcu
grace period is over and no one (allowedly) accesses it anymore.
But the _now functions ignore this completely. They free the object
directly even when a different context still tries to access it. This has
to be avoided and thus these functions must be removed and all functions
have to use batadv_hardif_free_ref.

From: Jisheng Zhang <jszhang@marvell.com>
commit 918f4cbd4340ddd1eb389cd8efa3b07ac74ec4c0 upstream.
After commit 52221610dd84 ("mmc: sdhci: Improve external VDD regulator
support"), for the VDD is supplied via external regulators, we ignore
the code to convert a VDD voltage request into one of the standard
SDHCI voltage levels, then program it in the SDHCI_POWER_CONTROL. This
brings two issues:
1. SDHCI_QUIRK2_CARD_ON_NEEDS_BUS_ON quirk isn't handled properly any
more.
2. What's more, once SDHCI_POWER_ON bit is set, some controllers such
as the sdhci-pxav3 used in marvell berlin SoCs require the voltage
levels programming in the SDHCI_POWER_CONTROL register, even the VDD
is supplied by external regulator. So the host in marvell berlin SoCs
still works fine after the commit. However, commit 3cbc6123a93d ("mmc:
sdhci: Set SDHCI_POWER_ON with external vmmc") sets the SDHCI_POWER_ON
bit, this would make the host in marvell berlin SoCs won't work any
more with external vmmc.
This patch restores the behavior when setting VDD through external
regulator by moving the call of mmc_regulator_set_ocr() to the end
of sdhci_set_power() function.
After this patch, the sdcard on Marvell Berlin SoC boards work again.
