Let's make all IPVS sysctls writtable even when
network namespace is owned by non-initial user namespace.
Let's make a few sysctls to be read-only for non-privileged users:
- sync_qlen_max
- sync_sock_size
- run_estimation
- est_cpulist
- est_nice
I'm trying to be conservative with this to prevent
introducing any security issues in there. Maybe,
we can allow more sysctls to be writable, but let's
do this on-demand and when we see real use-case.
This patch is motivated by user request in the LXC
project [1]. Having this can help with running some
Kubernetes [2] or Docker Swarm [3] workloads inside the system
containers.

Currently the ipq806x dwmac driver is almost always used attached to the
CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii".
Some device came up with a special configuration where the PHY is
directly attached to the GMAC port and in those case phy-mode needs to
be set to "rgmii-id" to make the PHY correctly work and receive packets.
Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id"
(or variants) mode is set, the mode is rejected and probe fails.
Add support also for these phy-modes to correctly setup PHYs that requires
delay applied to tx/rx.

Enhance the error reporting mechanism in the switchdev framework to
provide more informative and user-friendly error messages.
Following feedback from users struggling to understand the implications
of error messages like "failed (err=-28) to add object (id=2)", this
update aims to clarify what operation failed and how this might impact
the system or network.
With this change, error messages now include a description of the failed
operation, the specific object involved, and a brief explanation of the
potential impact on the system. This approach helps administrators and
developers better understand the context and severity of errors,
facilitating quicker and more effective troubleshooting.
Example of the improved logging:
[ 70.516446] ksz-switch spi0.0 uplink: Failed to add Port Multicast
Database entry (object id=2) with error: -ENOSPC (-28).
[ 70.516446] Failure in updating the port's Multicast Database could
lead to multicast forwarding issues.
[ 70.516446] Current HW/SW setup lacks sufficient resources.
This comprehensive update includes handling for a range of switchdev
object IDs, ensuring that most operations within the switchdev framework
benefit from clearer error reporting.

When a broadcast AppleTalk packet is received, prefer queuing it on the
socket whose address matches the address of the interface that received
the packet (and is listening on the correct port). Userspace
applications that handle such packets will usually send a response on
the same socket that received the packet; this fix allows the response
to be sent on the correct interface.
If a socket matching the interface's address is not found, an arbitrary
socket listening on the correct port will be used, if any. This matches
the implementation's previous behavior.
Fixes atalkd's responses to network information requests when multiple
network interfaces are configured to use AppleTalk.

Introduce a tracepoint for icmp_send, which can help users to get more
detail information conveniently when icmp abnormal events happen.
1. Giving an usecase example:
=============================
When an application experiences packet loss due to an unreachable UDP
destination port, the kernel will send an exception message through the
icmp_send function. By adding a trace point for icmp_send, developers or
system administrators can obtain detailed information about the UDP
packet loss, including the type, code, source address, destination address,
source port, and destination port. This facilitates the trouble-shooting
of UDP packet loss issues especially for those network-service
applications.
2. Operation Instructions:
==========================
Switch to the tracing directory.
cd /sys/kernel/tracing
Filter for destination port unreachable.
echo "type==3 && code==3" > events/icmp/icmp_send/filter
Enable trace event.
echo 1 > events/icmp/icmp_send/enable
3. Result View:
================
udp_client_erro-11370 [002] ...s.12 124.728002:
icmp_send: icmp_send: type=3, code=3.

Oleksij Rempel says:
====================
add DCB and DSCP support for KSZ switches
This patch series is aimed at improving support for DCB (Data Center
Bridging) and DSCP (Differentiated Services Code Point) on KSZ switches.
The main goal is to introduce global DSCP and PCP (Priority Code Point)
mapping support, addressing the limitation of KSZ switches not having
per-port DSCP priority mapping. This involves extending the DSA
framework with new callbacks for managing trust settings for global DSCP
and PCP maps. Additionally, we introduce IEEE 802.1q helpers for default
configurations, benefiting other drivers too.
Change logs are in separate patches.
Compared to v6 this series includes some new patches for DSCP global
mapping support and QoS selftest script for KSZ9477 switches.

KSZ88X3 switches have different behavior on different ports:
- It seems to be not possible to disable VLAN PCP classification on port
2. It means, as soon as mutliqueue support is enabled, frames with
VLAN tag will get PCP prios. This behavior do not affect Port 1 -
it is possible to disable PCP prios.
- DSCP classification is not working on Port 2.
Since there are still usable configuration combinations, I added some
quirks to make sure user will get appropriate error message if not
possible configuration is chosen.

This adds a special global buffer pool (in the end) for reserved pages.
Using a reserved pool for LZ4 decompression significantly reduces the
time spent on extra temporary page allocation for the extreme cases in
low memory scenarios.
The table below shows the reduction in time spent on page allocation for
LZ4 decompression when using a reserved pool. The results were obtained
from multi-app launch benchmarks on ARM64 Android devices running the
5.15 kernel with an 8-core CPU and 8GB of memory. In the benchmark, we
launched 16 frequently-used apps, and the camera app was the last one in
each round. The data in the table is the average time of camera app for
each round.
After using the reserved pool, there was an average improvement of 150ms
in the overall launch time of our camera app, which was obtained from
the systrace log.
+--------------+---------------+--------------+---------+
| | w/o page pool | w/ page pool | diff |
+--------------+---------------+--------------+---------+
| Average (ms) | 3434 | 21 | -99.38% |
+--------------+---------------+--------------+---------+
Based on the benchmark logs, 64 pages are sufficient for 95% of
scenarios. This value can be adjusted with a module parameter
`reserved_pages`. The default value is 0.
This pool is currently only used for the LZ4 decompressor, but it can be
applied to more decompressors if needed.

It will cost more time if compressed buffers are allocated on demand for
low-latency algorithms (like lz4) so EROFS uses per-CPU buffers to keep
compressed data if in-place decompression is unfulfilled. While it is kind
of wasteful of memory for a device with hundreds of CPUs, and only a small
number of CPUs concurrently decompress most of the time.
This patch renames it as 'global buffer pool' and makes it configurable.
This allows two or more CPUs to share a common buffer to reduce memory
occupation.

So, this commit only provide UAPI macros for UAPI structs that will

Both dma_unmap_sgtable() and sg_free_table() in spi_unmap_buf_attrs()
have checks for orig_nents against 0. No need to duplicate this.
All the same applies to other DMA mapping API calls.
Also note, there is no other user in the kernel that does this kind of
checks.

*-objs suffix is reserved rather for (user-space) host programs while
usually *-y suffix is used for kernel drivers (although *-objs works
for that purpose for now).
Let's correct the old usages of *-objs in Makefiles.
