There's different mathematical definitions (truncated, floored, rounded,
etc.) and different languages have chosen different definitions [0][1].
E.g., languages/libraries that follow Knuth use a different mathematical
definition than C uses. This patch specifies which definition BPF uses,
as verified by Eduard [2] and others.

pull-request: bpf-next 2023-10-16
We've added 90 non-merge commits during the last 25 day(s) which contain
a total of 120 files changed, 3519 insertions(+), 895 deletions(-).
The main changes are:
1) Add missed stats for kprobes to retrieve the number of missed kprobe
executions and subsequent executions of BPF programs, from Jiri Olsa.
2) Add cgroup BPF sockaddr hooks for unix sockets. The use case is
for systemd to reimplement the LogNamespace feature which allows
running multiple instances of systemd-journald to process the logs
of different services, from Daan De Meyer.
3) Implement BPF CPUv4 support for s390x BPF JIT, from Ilya Leoshkevich.
4) Improve BPF verifier log output for scalar registers to better
disambiguate their internal state wrt defaults vs min/max values
matching, from Andrii Nakryiko.
5) Extend the BPF fib lookup helpers for IPv4/IPv6 to support retrieving
the source IP address with a new BPF_FIB_LOOKUP_SRC flag,
from Martynas Pumputis.
6) Add support for open-coded task_vma iterator to help with symbolization
for BPF-collected user stacks, from Dave Marchevsky.
7) Add libbpf getters for accessing individual BPF ring buffers which
is useful for polling them individually, for example, from Martin Kelly.
8) Extend AF_XDP selftests to validate the SHARED_UMEM feature,
from Tushar Vyavahare.
9) Improve BPF selftests cross-building support for riscv arch,
from Björn Töpel.
10) Add the ability to pin a BPF timer to the same calling CPU,
from David Vernet.
11) Fix libbpf's bpf_tracing.h macros for riscv to use the generic
implementation of PT_REGS_SYSCALL_REGS() to access syscall arguments,
from Alexandre Ghiti.
12) Extend libbpf to support symbol versioning for uprobes, from Hengqi Chen.
13) Fix bpftool's skeleton code generation to guarantee that ELF data
is 8 byte aligned, from Ian Rogers.
14) Inherit system-wide cpu_mitigations_off() setting for Spectre v1/v4
security mitigations in BPF verifier, from Yafang Shao.
15) Annotate struct bpf_stack_map with __counted_by attribute to prepare
BPF side for upcoming __counted_by compiler support, from Kees Cook.

TCP pingpong threshold is 1 by default. But some applications, like SQL DB
may prefer a higher pingpong threshold to activate delayed acks in quick
ack mode for better performance.
The pingpong threshold and related code were changed to 3 in the year
2019 in:
commit 4a41f453bedf ("tcp: change pingpong threshold to 3")
And reverted to 1 in the year 2022 in:
commit 4d8f24eeedc5 ("Revert "tcp: change pingpong threshold to 3"")
There is no single value that fits all applications.
Add net.ipv4.tcp_pingpong_thresh sysctl tunable, so it can be tuned for
optimal performance based on the application needs.

Pull irq fixes from Thomas Gleixner:
"A set of updates for interrupt chip drivers:
- Fix the fail of the Qualcomm PDC driver on v3.2 hardware which is
caused by a control bit being moved to a different location
- Update the SM8150 device tree PDC resource so the version register
can be read
- Make the Renesas RZG2L driver correct for interrupts which are
outside of the LSB in the TSSR register by using the proper macro
for calculating the mask
- Document the Renesas RZ2GL device tree binding correctly and update
them for a few devices which faul to boot otherwise
- Use the proper accessor in the RZ2GL driver instead of blindly
dereferencing an unchecked pointer
- Make GICv3 handle the dma-non-coherent attribute correctly
- Ensure that all interrupt controller nodes on RISCV are marked as
initialized correctly
Maintainer changes:
- Add a new entry for GIC interrupt controllers and assign Marc
Zyngier as the maintainer
- Remove Marc Zyngier from the core and driver maintainer entries as
he is burried in work and short of time to handle that.
Thanks to Marc for all the great work he has done in the past couple
of years!
Also note that commit 5873d380f4c0 ("irqchip/qcom-pdc: Add support for
v3.2 HW") has a incorrect SOB chain.
The real author is Neil. His patch was posted by Dmitry once and Neil
picked it up from the list and reposted it with the bogus SOB chain.
Not a big deal, but worth to mention. I wanted to fix that up, but
then got distracted and Marc piled more changes on top. So I decided
to leave it as is instead of rebasing world"

is a redundant information in yaml file, moreover, may lead to
inconsistencies.

...
name: pin
enum-name: dpll_a_pin
attributes:
...
-
name: parent-id
type: u32
...
-
name: pin-parent-device

type: u32 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

The GIC v3 specifications allow redistributors and ITSes interconnect
ports used to access memory to be wired up in a way that makes the
respective initiators/memory observers non-coherent.
Add the standard dma-noncoherent property to the GICv3 bindings to
allow firmware to describe the redistributors/ITSes components and
interconnect ports behaviour in system designs where the redistributors
and ITSes are not coherent with the CPU.

Document RZ/G2UL (R9A07G043U) IRQC bindings. The IRQC block on RZ/G2UL SoC
is almost identical to one found on the RZ/G2L SoC the only difference
being it can support BUS_ERR_INT for which it has additional registers.
Hence new generic compatible string "renesas,r9a07g043u-irqc" is added
for RZ/G2UL SoC.
Now that we have additional interrupt for RZ/G2UL and RZ/Five SoC
interrupt-names property is added so that we can parse them based on
names.
While at it updated the example node to four spaces and added

The 'msi' child node schema is missing constraints on additional properties.
It turns out it is incomplete and properties for it are documented in the
parent node by mistake. Move the reference to msi-controller.yaml and
the custom properties to the 'msi' node. Adding 'unevaluatedProperties'
ensures all the properties in the 'msi' node are documented.
With the schema corrected, a minimal interrupt controller node is needed
to properly decode the interrupt properties since the example has
multiple interrupt parents.

Pull rtla fixes from Daniel Bristot de Oliveira:
"rtla (Real-Time Linux Analysis) tool fixes.
Timerlat auto-analysis:
- Timerlat is reporting thread interference time without thread noise
events occurrence. It was caused because the thread interference
variable was not reset after the analysis of a timerlat activation
that did not hit the threshold.
- The IRQ handler delay is estimated from the delta of the IRQ
latency reported by timerlat, and the timestamp from IRQ handler
start event. If the delta is near-zero, the drift from the external
clock and the trace event and/or the overhead can cause the value
to be negative. If the value is negative, print a zero-delay.
- IRQ handlers happening after the timerlat thread event but before
the stop tracing were being reported as IRQ that happened before
the *current* IRQ occurrence. Ignore Previous IRQ noise in this
condition because they are valid only for the *next* timerlat
activation.
Timerlat user-space:
- Timerlat is stopping all user-space thread if a CPU becomes
offline. Do not stop the entire tool if a CPU is/become offline,
but only the thread of the unavailable CPU. Stop the tool only, if
all threads leave because the CPUs become/are offline.
man-pages:
- Fix command line example in timerlat hist man page"

enum-as-flags can be used when enum declares bit positions but
we want to carry bitmask in an attribute. If the definition
is already provided as flags there's no need to indicate
the flag-iness of the attribute.

The COPS Appletalk support is very old, never said to actually work
properly, and the firmware code for the devices are under a very suspect
license. Remove it all to clear up the license issue, if it is still
needed and actually used by anyone, we can add it back later once the
license is cleared up.

This change adds a sysctl to opt-out of RFC4862 section 5.5.3e's valid
lifetime derivation mechanism.
RFC4862 section 5.5.3e prescribes that the valid lifetime in a Router
Advertisement PIO shall be ignored if it less than 2 hours and to reset
the lifetime of the corresponding address to 2 hours. An in-progress
6man draft (see draft-ietf-6man-slaac-renum-07 section 4.2) is currently
looking to remove this mechanism. While this draft has not been moving
particularly quickly for other reasons, there is widespread consensus on
section 4.2 which updates RFC4862 section 5.5.3e.
