- Improve sched class lifetime handling

- Add backup nexthop ID support for bridge

- Implement drop reasons support in openvswitch

- Several data races annotations and fixes

- Constify the sk parameter of routing functions

- Prepend kernel version to netconsole message

Protocols:

- Implement support for TCP probing the peer being under memory
pressure

- Remove hard coded limitation on IPv6 specific info placement inside
the socket struct

- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated per
socket scaling factor

max connections per lgr negotiation, max links per lgr negotiation

BPF:

- Multi-buffer support in AF_XDP

- Add multi uprobe BPF links for attaching multiple uprobes and usdt
probes, which is significantly faster and saves extra fds

- Implement an fd-based tc BPF attach API (TCX) and BPF link support
on top of it

- Add SO_REUSEPORT support for TC bpf_sk_assign

- Support new instructions from cpu v4 to simplify the generated code
and feature completeness, for x86, arm64, riscv64

- Add uprobe support for the bpf_get_func_ip helper

- Check skb ownership against full socket

- Support for up to 12 arguments in BPF trampoline

- Extend link_info for kprobe_multi and perf_event links

Netfilter:

- Speed-up process exit by aborting ruleset validation if a fatal
signal is pending

- Allow NLA_POLICY_MASK to be used with BE16/BE32 types

Driver API:

- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the
need for raw ioctl() handling in drivers

- Simplify genetlink dump operations (doit/dumpit) providing them the
common information already populated in struct genl_info

- Extend and use the yaml devlink specs to [re]generate the split ops

- Introduce devlink selective dumps, to allow SF filtering SF based
on handle and other attributes

- Add yaml netlink spec for netlink-raw families, allow route, link
and address related queries via the ynl tool

Jakub Kicinski says:

====================
genetlink: provide struct genl_info to dumps

One of the biggest (which is not to say only) annoyances with genetlink
handling today is that doit and dumpit need some of the same information,
but it is passed to them in completely different structs.

The implementations commonly end up writing a _fill() method which
populates a message and have to pass at least 6 parameters. 3 of which
are extracted manually from request info.

After a lot of umming and ahing I decided to populate struct genl_info
for dumps, without trying to factor out only the common parts.
This makes the adoption easiest.

In the future we may add a new version of dump which takes
struct genl_info *info as the second argument, instead of
struct netlink_callback *cb. For now developers have to call
genl_info_dump(cb) to get the info.

Typical genetlink families no longer get exposed to netlink protocol
internals like pid and seq numbers.

v3:
- correct the condition in ethtool code (patch 10)
v2: https://lore.kernel.org/all/20230810233845.2318049-1-kuba@kernel.org/
- replace the GENL_INFO_NTF() macro with init helper
- fix the commit messages

ethtool: netlink: always pass genl_info to .prepare_data

We had a number of bugs in the past because developers forgot
to fully test dumps, which pass NULL as info to .prepare_data.
.prepare_data implementations would try to access info->extack
leading to a null-deref.

Now that dumps and notifications can access struct genl_info
we can pass it in, and remove the info null checks.

Merge branch 'sg_nents' into rdma.git for-next

From Maor Gottlieb
====================

Fix the use of nents and orig_nents in the sg table append helpers. The
nents should be used by the DMA layer to store the number of DMA mapped
sges, the orig_nents is the number of CPU sges.

Since the sg append logic doesn't always create a SGL with exactly
orig_nents entries store a total_nents as well to allow the table to be
properly free'd and reorganize the freeing logic to share across all the
use cases.

Merge branch 'ptp-virtual-clocks-and-timestamping'

Yangbo Lu says:

====================
ptp: support virtual clocks and timestamping

Current PTP driver exposes one PTP device to user which binds network
interface/interfaces to provide timestamping. Actually we have a way
utilizing timecounter/cyclecounter to virtualize any number of PTP
clocks based on a same free running physical clock for using.
The purpose of having multiple PTP virtual clocks is for user space
to directly/easily use them for multiple domains synchronization.

user
space: ^ ^
| SO_TIMESTAMPING new flag: | Packets with
| SOF_TIMESTAMPING_BIND_PHC | TX/RX HW timestamps
v v

sock: | sock (new member sk_bind_phc) |

v v
+--------------+--------------+--------------+
vclock: | ptp1 | ptp2 | ptpN |
+--------------+--------------+--------------+
pclock: | ptp0 free running |
+--------------------------------------------+

The block diagram may explain how it works. Besides the PTP virtual
clocks, the packet HW timestamp converting to the bound PHC is also
done in sock driver. For user space, PTP virtual clocks can be
created via sysfs, and extended SO_TIMESTAMPING API (new flag
SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock
for timestamping.

The test tool timestamping.c (together with linuxptp phc_ctl tool) can
be used to verify:

- Protected concurrency of ptp->num_vclocks accessing.
- Supported PHC vclocks query via ethtool.
- Extended SO_TIMESTAMPING API for PHC binding.
- Converted HW timestamps to PHC bound, instead of previous
binding domain value to PHC idea.
- Other minor fixes.
Changes for v4:
- Used do_aux_work callback for vclock refreshing instead.
- Used unsigned int for vclocks number, and max_vclocks
for limitiation.
- Fixed mutex locking.
- Dynamically allocated memory for vclock index storage.
- Removed ethtool ioctl command for vclocks getting.
- Updated doc for ethtool phc vclocks get.
- Converted to mptcp_setsockopt_sol_socket_timestamping().
- Passed so_timestamping for sock_set_timestamping.
- Fixed checkpatch/build.
- Other minor fixed.
Changes for v5:
- Fixed checkpatch/build/bug reported by test robot.
