MIPS: Fix MSA asm warnings in control reg accessors
Building an MSA capable kernel with a toolchain that supports MSA
produces warnings such as this:
CC arch/mips/kernel/cpu-probe.o
{standard input}: Assembler messages:
{standard input}:4786: Warning: the `msa' extension requires 64-bit FPRs
This is due to ".set msa" without ".set fp=64" in the inline assembly of
control register accessors, since MSA requires the 64-bit FPU registers
(FR=1). Add the missing fp=64 in these functions to silence the
warnings.

MIPS: Lantiq: Register IRQ handler for virtual IRQ number
We used the hardware IRQ number to register the IRQ handler and not the
virtual one. This probably caused some problems because the hardware
IRQ numbers are only unique for each IRQ controller and not in the
system. The virtual IRQ number is managed by Linux and unique in the
system. This was probably the reason there was a gab of 8 IRQ numbers added
before the numbers used for the lantiq IRQ controller. With the current
setup the hardware and the virtual IRQ numbers are the same.

MIPS: hpet: Increase HPET_MIN_PROG_DELTA and decrease HPET_MIN_CYCLES
At first, we prefer to use mips clockevent device, so we decrease the
rating of hpet clockevent device.
For hpet, if HPET_MIN_PROG_DELTA (minimum delta of hpet programming) is
too small and HPET_MIN_CYCLES (threshold of -ETIME checking) is too
large, then hpet_next_event() can easily return -ETIME. After commit
c6eb3f70d44828 ("hrtimer: Get rid of hrtimer softirq") this will cause
a RCU stall.
So, HPET_MIN_PROG_DELTA must be sufficient that we don't re-trip the
-ETIME check -- if we do, we will return -ETIME, forward the next event
time, try to set it, return -ETIME again, and basically lock the system
up. Meanwhile, HPET_MIN_CYCLES doesn't need to be too large, 16 cycles
is enough.
This solution is similar to commit
f9eccf24615672 ("clocksource/drivers
/vt8500: Increase the minimum delta").
By the way, this patch ensures hpet count/compare to be 32-bit long.

The well-spotted fallocate undo fix is good in most cases, but not when
fallocate failed on the very first page. index 0 then passes lend -1

undo every fallocation throughout the file, unrestricted by the current

lend -1 is treated as truncation, which makes it keep on retrying until
every page has gone, but those already fully instantiated will never go

apparmor: fix oops, validate buffer size in apparmor_setprocattr()
When proc_pid_attr_write() was changed to use memdup_user apparmor's
(interface violating) assumption that the setprocattr buffer was always
a single page was violated.
The size test is not strictly speaking needed as proc_pid_attr_write()
will reject anything larger, but for the sake of robustness we can keep
it in.
SMACK and SELinux look safe to me, but somebody else should probably
have a look just in case.
Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>
modified for the case that apparmor provides null termination.

This reverts commit
2f36db71009304b3f0b95afacd8eba1f9f046b87.
It fixed a local root exploit but also introduced a dependency on
the lower file system implementing an mmap operation just to open a file,
which is a bit of a heavy hammer. The right fix is to have mmap depend
on the existence of the mmap handler instead.

perf/core: Fix pmu::filter_match for SW-led groups
The following commit:
66eb579e66ec ("perf: allow for PMU-specific event filtering")
added the pmu::filter_match() callback. This was intended to
avoid HW constraints on events from resulting in extremely
pessimistic scheduling.
However, pmu::filter_match() is only called for the leader of each event
group. When the leader is a SW event, we do not filter the groups, and
may fail at pmu::add() time, and when this happens we'll give up on
scheduling any event groups later in the list until they are rotated
ahead of the failing group.
This can result in extremely sub-optimal event scheduling behaviour,
e.g. if running the following on a big.LITTLE platform:
$ taskset -c 0 ./perf stat \
-e 'a57{context-switches,armv8_cortex_a57/config=0x11/}' \
-e 'a53{context-switches,armv8_cortex_a53/config=0x11/}' \
ls
<not counted> context-switches (0.00%)
<not counted> armv8_cortex_a57/config=0x11/ (0.00%)
24 context-switches (37.36%)
57589154 armv8_cortex_a53/config=0x11/ (37.36%)
Here the 'a53' event group was always eligible to be scheduled, but
the 'a57' group never eligible to be scheduled, as the task was always
affine to a Cortex-A53 CPU. The SW (group leader) event in the 'a57'
group was eligible, but the HW event failed at pmu::add() time,
resulting in ctx_flexible_sched_in giving up on scheduling further
groups with HW events.
One way of avoiding this is to check pmu::filter_match() on siblings
as well as the group leader. If any of these fail their
pmu::filter_match() call, we must skip the entire group before
attempting to add any events.

net: fix decnet rtnexthop parsing
dn_fib_count_nhs() could enter an infinite loop if nhp->rtnh_len == 0
(i.e. if userspace passes a malformed netlink message).
Let's use the helpers from net/nexthop.h which take care of all this
stuff. We can do exactly the same as e.g. fib_count_nexthops() and
fib_get_nhs() from net/ipv4/fib_semantics.c.
This fixes the softlockup for me.

ACPICA: Namespace: Fix namespace/interpreter lock ordering
There is a lock order issue in acpi_load_tables(). The namespace lock
is held before holding the interpreter lock.
With ACPI_MUTEX_DEBUG enabled in the kernel, this is printed to the
log during boot:
[ 0.885699] ACPI Error: Invalid acquire order: Thread

The issue has been introduced by the following commit:

ACPICA Commit:
bfe03ffcde8ed56a7eae38ea0b188aeb12f9c52e
Subject: ACPICA: Namespace: Fix a regression that MLC support triggers
dead lock in dynamic table loading
Which fixed a deadlock issue for acpi_ns_load_table() in
acpi_ex_add_table() but didn't take care of the lock order in
acpi_ns_load_table() correctly.
Originally (before the above commit), ACPICA used the
namespace/interpreter locks in the following 2 key code
paths:
1. Table loading:
acpi_ns_load_table
L(Namespace)
acpi_ns_parse_table
acpi_ns_one_complete_parse
U(Namespace)
2. Object evaluation:
acpi_ns_evaluate
L(Interpreter)
acpi_ps_execute_method
U(Interpreter)
acpi_ns_load_table
L(Namespace)
U(Namespace)
acpi_ev_initialize_region
L(Namespace)
U(Namespace)
address_space.setup
L(Namespace)
U(Namespace)
address_space.handler
L(Namespace)
U(Namespace)
acpi_os_wait_semaphore
acpi_os_acquire_mutex
acpi_os_sleep
L(Interpreter)
U(Interpreter)
During runtime, while acpi_ns_evaluate is called, the lock order is
always Interpreter -> Namespace.
In turn, the problematic commit acquires the locks in the following
order:
3. Table loading:
acpi_ns_load_table
L(Namespace)
acpi_ns_parse_table
L(Interpreter)
acpi_ns_one_complete_parse
U(Interpreter)
U(Namespace)
To fix the lock order issue, move the interpreter lock to
acpi_ns_load_table() to ensure the lock order correctness:
4. Table loading:
acpi_ns_load_table
L(Interpreter)
L(Namespace)
acpi_ns_parse_table
acpi_ns_one_complete_parse
U(Namespace)
U(Interpreter)
However, this doesn't fix the current design issues related to the
namespace lock. For example, we can notice that in acpi_ns_evaluate(),
outside of acpi_ns_load_table(), the namespace objects may be created
by the named object creation control methods. And the creation of
the method-owned namespace objects are not locked by the namespace
lock. This patch doesn't try to fix such kind of existing issues.

bonding: fix enslavement slave link notifications
Currently, link notifications are not sent by
bond_set_slave_link_state() upon enslavement if
the slave is enslaved when up.
This happens because slave->link default init value
is 0, which is the same as BOND_LINK_UP, resulting
in bond_set_slave_link_state() ignoring this transition.
This patch sets the default value of slave->link to
BOND_LINK_NOCHANGE, assuring it will count as a state
transition and thus trigger notification logic.

fbde2d7d8290 ("MIPS: Add generic SMP IPI support") introduced
code which calls irq_find_matching_host with a NULL node parameter in
order to discover IPI IRQ domains which are not associated with the DT
root node's interrupt parent. This suggests that implementations of IPI
IRQ domains should effectively ignore the node parameter if it is NULL
and search purely based upon the bus token. Commit

("irqchip/mips-gic: Add a IPI hierarchy domain") did not do this when

leads to no IPI domain being discovered and a NULL pointer dereference

irqchip/mips-gic: Map to VPs using HW VPNum
When mapping an interrupt to a VP(E) we must use the identifier for the
VP that the hardware expects, and this does not always match up with the
Linux CPU number. Commit
d46812bb0bef ("irqchip: mips-gic: Use HW IDs
for VPE_OTHER_ADDR") corrected this for the cases that existed at the
time it was written, but commit
2af70a962070 ("irqchip/mips-gic: Add a
IPI hierarchy domain") added another case before the former patch was
merged. This leads to incorrectly using Linux CPU numbers when mapping
interrupts to VPs, which breaks on certain systems such as those with
multi-core I6400 CPUs. Fix by adding the appropriate call to
mips_cm_vp_id() to retrieve the expected VP identifier.

cdc_ncm: workaround for EM7455 "silent" data interface
Several Lenovo users have reported problems with their Sierra
Wireless EM7455 modem. The driver has loaded successfully and
the MBIM management channel has appeared to work, including
establishing a connection to the mobile network. But no frames
have been received over the data interface.
The problem affects all EM7455 and MC7455, and is assumed to
affect other modems based on the same Qualcomm chipset and
baseband firmware.
Testing narrowed the problem down to what seems to be a
firmware timing bug during initialization. Adding a short sleep
while probing is sufficient to make the problem disappear.
Experiments have shown that 1-2 ms is too little to have any
effect, while 10-20 ms is enough to reliably succeed.

Revert "gpiolib: Split GPIO flags parsing and GPIO configuration"
This reverts commit
923b93e451db876d1479d3e4458fce14fec31d1c.
Make sure consumers do not overwrite gpio flags for pins that have
already been claimed.
While adding support for gpio drivers to refuse a request using
unsupported flags, the order of when the requested flag was checked and
the new flags were applied was reversed to that consumers could
overwrite flags for already requested gpios.
This not only affects device-tree setups where two drivers could request
the same gpio using conflicting configurations, but also allowed user
space to clear gpio flags for already claimed pins simply by attempting
to export them through the sysfs interface. By for example clearing the
FLAG_ACTIVE_LOW flag this way, user space could effectively change the
polarity of a signal.
Reverting this change obviously prevents gpio drivers from doing sanity
checks on the flags in their request callbacks. Fortunately only one
recently added driver (gpio-tps65218 in v4.6) appears to do this, and a
follow up patch could restore this functionality through a different
interface.

gpio: sch: Fix Oops on module load on Asus Eee PC 1201
This fixes the issue descirbe in bug 117531
(https://bugzilla.kernel.org/show_bug.cgi?id=117531).
It's a regression introduced in linux 4.5 that causes a Oops at load of
gpio_sch and prevents powering off the computer.
The issue is that sch_gpio_reg_set is called in sch_gpio_probe before
gpio_chip data is initialized with the pointer to the sch_gpio struct. As
sch_gpio_reg_set calls gpiochip_get_data, it returns NULL which causes
the Oops.
The patch follows Mika's advice (https://lkml.org/lkml/2016/5/9/61) and
consists in modifying sch_gpio_reg_get and sch_gpio_reg_set to take a
sch_gpio struct directly instead of a gpio_chip, which avoids the call to
gpiochip_get_data.

cpuidle: Fix last_residency division
Snooze is a poll idle state in powernv and pseries platforms. Snooze
has a timeout so that if a CPU stays in snooze for more than target
residency of the next available idle state, then it would exit
thereby giving chance to the cpuidle governor to re-evaluate and
promote the CPU to a deeper idle state. Therefore whenever snooze
exits due to this timeout, its last_residency will be target_residency
of the next deeper state.
Commit
e93e59ce5b85 "cpuidle: Replace ktime_get() with local_clock()"
changed the math around last_residency calculation. Specifically,
while converting last_residency value from nano- to microseconds, it
carries out right shift by 10. Because of that, in snooze timeout
exit scenarios last_residency calculated is roughly 2.3% less than
target_residency of the next available state. This pattern is picked
up by get_typical_interval() in the menu governor and therefore
expected_interval in menu_select() is frequently less than the
target_residency of any state other than snooze.
Due to this we are entering snooze at a higher rate, thereby
affecting the single thread performance.
Fix this by using more precise division via ktime_us_delta().

enc28j60: Fix race condition in enc28j60 driver
The interrupt worker code for the enc28j60 relies only on the TXIF flag to
determinate if the packet transmission was completed. However the datasheet
specifies in section 12.1.3 that TXERIF will clear the TXRTS after a
transmit abort. Also in section 12.1.4 that TXIF will be set
when TXRTS transitions from '1' to '0'. Therefore the TXIF flag is enabled
during transmission errors.
This causes a race condition, since the worker code will invoke
enc28j60_tx_clear() -> netif_wake_queue(), potentially invoking the
ndo_start_xmit function to send a new packet. The enc28j60_send_packet function
uses a workqueue that invokes enc28j60_hw_tx(). In between this function is
called, the worker from the interrupt handler will enter the path for error
handler because of the TXERIF flag, causing to invoke enc28j60_tx_clear() again
and releasing the packet scheduled for transmission, causing a kernel crash with
due a NULL pointer.
These crashes due a NULL pointer were observed under stress conditions of the
device. A BUG_ON() sequence was used to validate the issue was fixed, and has
been running without problems for 2 years now.

net: stmmac: Fix null-function call in ISR on stmmac1000
(resent due to overhelpful mail client corrupting patch)
At least on Meson GXBB, the CORE_IRQ_MTL_RX_OVERFLOW interrupt is thrown
with the stmmac1000 driver, which does not support set_rx_tail_ptr. With
this patch and the clock fixes, 1G ethernet works on ODROID-C2.
