Merge tag 'for-4.20-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"This is the first batch with fixes and some nice performance
improvements.
Preliminary results show eg. more files/sec in fsmark, better perf on
multi-threaded workloads (filebench, dbench), fewer context switches
and overall better memory allocation characteristics (multiple
benchmarks).
Apart from general performance, there's an improvement for qgroups +
balance workload that's been troubling our users.
Note for stable: there are 20+ patches tagged for stable, out of 90.
Not all of them apply cleanly on all stable versions but the conflicts
are mostly due to simple cleanups and resolving should be obvious. The
fixes are otherwise independent.
Performance improvements:
- transition between blocking and spinning modes of path is gone,
which originally resulted to more unnecessary wakeups and updates
to the path locks, the effects are measurable and improve latency
and scalability
- qgroups: first batch of changes that should speedup balancing with
qgroups on, skip quota accounting on unchanged subtrees, overall
gain is about 30+% in runtime
- use rb-tree with cached first node for several structures, small
improvement to avoid pointer chasing
Fixes:
- trim
- fix: some blockgroups could have been missed if their logical
address was past the total filesystem size (ie. after a lot of
balancing)
- better error reporting, after processing blockgroups and whole
device
- fix: continue trimming block groups after an error is
encountered
- check for trim support of the device earlier and avoid some
unnecessary work
- less interaction with transaction commit that improves latency
on slower storage (eg. image files over NFS)
- fsync
- fix warning when replaying log after fsync of a O_TMPFILE
- fix wrong dentries after fsync of file that got its parent
replaced
- qgroups: fix rescan that might misc some dirty groups
- don't clean dirty pages during buffered writes, this could lead to
lost updates in some corner cases
- some block groups could have been delayed in creation, if the
allocation triggered another one
- error handling improvements
Cleanups:
- removed unused struct members and variables
- function return type cleanups
- delayed refs code refactoring
- protect against deadlock that could be caused by crafted image that
tries to allocate from a tree that's locked already"

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman: "I have been slowly sorting out siginfo and this is the culmination of that work. The primary result is in several ways the signal infrastructure has been made less error prone. The code has been updated so that manually specifying SEND_SIG_FORCED is never necessary. The conversion to the new siginfo sending functions is now complete, which makes it difficult to send a signal without filling in the proper siginfo fields. At the tail end of the patchset comes the optimization of decreasing the size of struct siginfo in the kernel from 128 bytes to about 48 bytes on 64bit. The fundamental observation that enables this is by definition none of the known ways to use struct siginfo uses the extra bytes. This comes at the cost of a small user space observable difference. For the rare case of siginfo being injected into the kernel only what can be copied into kernel_siginfo is delivered to the destination, the rest of the bytes are set to 0. For cases where the signal and the si_code are known this is safe, because we know those bytes are not used. For cases where the signal and si_code combination is unknown the bits that won't fit into struct kernel_siginfo are tested to verify they are zero, and the send fails if they are not. I made an extensive search through userspace code and I could not find anything that would break because of the above change. If it turns out I did break something it will take just the revert of a single change to restore kernel_siginfo to the same size as userspace siginfo. Testing did reveal dependencies on preferring the signo passed to sigqueueinfo over si->signo, so bit the bullet and added the complexity necessary to handle that case. Testing also revealed bad things can happen if a negative signal number is passed into the system calls. Something no sane application will do but something a malicious program or a fuzzer might do. So I have fixed the code that performs the bounds checks to ensure negative signal numbers are handled" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (80 commits) signal: Guard against negative signal numbers in copy_siginfo_from_user32 signal: Guard against negative signal numbers in copy_siginfo_from_user signal: In sigqueueinfo prefer sig not si_signo signal: Use a smaller struct siginfo in the kernel signal: Distinguish between kernel_siginfo and siginfo signal: Introduce copy_siginfo_from_user and use it's return value signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE signal: Fail sigqueueinfo if si_signo != sig signal/sparc: Move EMT_TAGOVF into the generic siginfo.h signal/unicore32: Use force_sig_fault where appropriate signal/unicore32: Generate siginfo in ucs32_notify_die signal/unicore32: Use send_sig_fault where appropriate signal/arc: Use force_sig_fault where appropriate signal/arc: Push siginfo generation into unhandled_exception signal/ia64: Use force_sig_fault where appropriate signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn signal/ia64: Use the generic force_sigsegv in setup_frame signal/arm/kvm: Use send_sig_mceerr signal/arm: Use send_sig_fault where appropriate signal/arm: Use force_sig_fault where appropriate ... |

net/kconfig: Make QCOM_QMI_HELPERS available when COMPILE_TEST
The networking merge brought in the experimental support for the
Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a
dependency.
But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on
ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just
the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.
As a result, a "make allmodconfig" complains
WARNING: unmet direct dependencies detected for QCOM_QMI_HELPERS
Depends on [n]: ARCH_QCOM && NET [=y]
Selected by [m]:
- ATH10K_SNOC [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && ATH10K [=m] && (ARCH_QCOM || COMPILE_TEST [=y])
Fix the config-time warning by making QCOM_QMI_HELPERS available when
COMPILE_TEST, since the result seems to build fine.

tcp: add tcp_reset_xmit_timer() helper
With EDT model, SRTT no longer is inflated by pacing delays. This means that RTO and some other xmit timers might be setup incorrectly. This is particularly visible with either : - Very small enforced pacing rates (SO_MAX_PACING_RATE) - Reduced rto (from the default 200 ms) This can lead to TCP flows aborts in the worst case, or spurious retransmits in other cases. For example, this session gets far more throughput than the requested 80kbit : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 2.66 With the fix : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 0.12 EDT allows for better control of rtx timers, since TCP has a better idea of the earliest departure time of each skb in the rtx queue. We only have to eventually add to the timer the difference of the EDT time with current time. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

Revert "be2net: remove desc field from be_eq_obj"
The mentioned commit needs to be reverted because we cannot pass
string allocated on stack to request_irq(). This function stores
uses this pointer for later use (e.g. /proc/interrupts) so we need

net: socionext: Reset tx queue in ndo_stop
We observed that packets and bytes count are not reset
when user performs interface down. Eventually, tx queue is
exhausted and packets will not be sent out.

net: socionext: Add dummy PHY register read in phy_write()
There is a compatibility issue between RTL8211E implemented
in Developerbox and netsec ethernet controller IP.
Our MDIO controller stops MDC clock right after the write
access, but RTL8211E expects MDC clock must be kept toggling
for several clock cycle with MDIO high before entering
the IDLE state. Without keeping clock after write access,
write access is not correctly handled and register is not
updated.
To meet this requirement, netsec driver needs to issue dummy
read(e.g. read PHYID1(offset 0x2) register) right after write
access, to keep MDC clock.
We think this compatibility issue is a problem specific to
our MDIO controller and RTL8211E.

net: socionext: Stop PHY before resetting netsec
In ndo_stop, driver resets the netsec ethernet controller IP.
When the netsec IP is reset, HW running mode turns to NRM mode
and driver has to wait until this mode transition completes.
But mode transition to NRM will not complete if the PHY is
in normal operation state. Netsec IP requires PHY is in
power down state when it is reset.
This modification stops the PHY before resetting netsec.
Together with this modification, phy_addr is stored in netsec_priv
structure because ndev->phydev is not yet ready in ndo_init.

"The biggest change in this cycle is the conclusion of the big
'simplify RCU to two primary flavors' consolidation work - i.e.
there's a single RCU flavor for any kernel variant (PREEMPT and
!PREEMPT):
- Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a
single flavor similar to RCU-sched in !PREEMPT kernels and into a
single flavor similar to RCU-preempt (but also waiting on
preempt-disabled sequences of code) in PREEMPT kernels.
This branch also includes a refactoring of
rcu_{nmi,irq}_{enter,exit}() from Byungchul Park.
- Now that there is only one RCU flavor in any given running kernel,
the many "rsp" pointers are no longer required, and this cleanup
series removes them.
- This branch carries out additional cleanups made possible by the
RCU flavor consolidation, including inlining now-trivial
functions, updating comments and definitions, and removing
now-unneeded rcutorture scenarios.
- Now that there is only one flavor of RCU in any running kernel,
there is also only on rcu_data structure per CPU. This means that
the rcu_dynticks structure can be merged into the rcu_data
structure, a task taken on by this branch. This branch also
contains a -rt-related fix from Mike Galbraith.
There were also other updates:
- Documentation updates, including some good-eye catches from Joel
Fernandes.
- SRCU updates, most notably changes enabling call_srcu() to be
invoked very early in the boot sequence.
- Torture-test updates, including some preliminary work towards
making rcutorture better able to find problems that result in
insufficient grace-period forward progress.
- Initial changes to RCU to better promote forward progress of grace
periods, including fixing a bug found by Marius Hillenbrand and
David Woodhouse, with the fix suggested by Peter Zijlstra"

s390 updates for the 4.20 merge window
- Improved access control for the zcrypt driver, multiple device nodes
can now be created with different access control lists
- Extend the pkey API to provide random protected keys, this is useful
for encrypted swap device with ephemeral protected keys
- Add support for virtually mapped kernel stacks
- Rework the early boot code, this moves the memory detection into the

Pull LED updates from Jacek Anaszewski:
"We introduce LED pattern trigger - the idea that was proposed three
years ago now received enough attention and determination to drive it
to the successful end.
There is also one new LED class driver and couple of improvements to
the existing ones.
New LED class driver:
- add support for Panasonic AN30259A with related DT bindings
New LED trigger:
- introduce LED pattern trigger
leds-sc27xx-bltc:
- implement pattern_set/clear ops to enable support for pattern
trigger's hw_pattern sysfs file
Improvements to existing LED class drivers:
- leds-pwm: don't print error message on -EPROBE_DEFER
- leds-gpio: try to lookup gpiod from device
- leds-as3645a: convert to using %pOFn instead of device_node.name"

This is the bulk of GPIO changes for the v4.20 series:
Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO
lines as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can
use only the fastpatch callbacks to enable/disable irqs
like any normal irqchip, especially the gpiod_lock_as_irq()
has been improved to be callable in fastpath context.
A bunch of rework had to be done to achieve this but it is
a big win since I never liked to restrict this to slowpath.
The only call requireing slowpath was try_module_get() and
this is kept at the .request_resources() slowpath callback.
In the GPIO CEC driver this is a big win sine a single
line is used for both outgoing and incoming traffic, and
this needs to use IRQs for incoming traffic while actively
driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a
"cookie" (struct gpio_array) and a bitmap for setting or
getting multiple GPIO lines at once. This improvement
orginated in a specific need to speed up an OMAP1 driver and
has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot
of checks and code when we want things to go really fast.
The previous code would minimize the number of calls
down to the driver callbacks assuming the CPU speed was
orders of magnitude faster than the I/O latency, but this
assumption was wrong on several platforms: what we needed
to do was to profile and improve the speed on the hot
path of the array functions and this change is now
completed.
- Clean out the painful and hard to grasp BNF experiments
from the device tree bindings. Future approaches are looking
into using JSON schema for this purpose. (Rob Herring
is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and
other contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin
control driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver.
