Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextgrafted

Pull networking updates from Jakub Kicinski:
 "Core:

   - Add dedicated kmem_cache for typical/small skb->head, avoid having
     to access struct page at kfree time, and improve memory use.

   - Introduce sysctl to set default RPS configuration for new netdevs.

   - Define Netlink protocol specification format which can be used to
     describe messages used by each family and auto-generate parsers.
     Add tools for generating kernel data structures and uAPI headers.

   - Expose all net/core sysctls inside netns.

   - Remove 4s sleep in netpoll if carrier is instantly detected on
     boot.

   - Add configurable limit of MDB entries per port, and port-vlan.

   - Continue populating drop reasons throughout the stack.

   - Retire a handful of legacy Qdiscs and classifiers.

  Protocols:

   - Support IPv4 big TCP (TSO frames larger than 64kB).

   - Add IP_LOCAL_PORT_RANGE socket option, to control local port range
     on socket by socket basis.

   - Track and report in procfs number of MPTCP sockets used.

   - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
     manager.

   - IPv6: don't check net.ipv6.route.max_size and rely on garbage
     collection to free memory (similarly to IPv4).

   - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).

   - ICMP: add per-rate limit counters.

   - Add support for user scanning requests in ieee802154.

   - Remove static WEP support.

   - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
     reporting.

   - WiFi 7 EHT channel puncturing support (client & AP).

  BPF:

   - Add a rbtree data structure following the "next-gen data structure"
     precedent set by recently added linked list, that is, by using
     kfunc + kptr instead of adding a new BPF map type.

   - Expose XDP hints via kfuncs with initial support for RX hash and
     timestamp metadata.

   - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
     better support decap on GRE tunnel devices not operating in collect
     metadata.

   - Improve x86 JIT's codegen for PROBE_MEM runtime error checks.

   - Remove the need for trace_printk_lock for bpf_trace_printk and
     bpf_trace_vprintk helpers.

   - Extend libbpf's bpf_tracing.h support for tracing arguments of
     kprobes/uprobes and syscall as a special case.

   - Significantly reduce the search time for module symbols by
     livepatch and BPF.

   - Enable cpumasks to be used as kptrs, which is useful for tracing
     programs tracking which tasks end up running on which CPUs in
     different time intervals.

   - Add support for BPF trampoline on s390x and riscv64.

   - Add capability to export the XDP features supported by the NIC.

   - Add __bpf_kfunc tag for marking kernel functions as kfuncs.

   - Add cgroup.memory=nobpf kernel parameter option to disable BPF
     memory accounting for container environments.

  Netfilter:

   - Remove the CLUSTERIP target. It has been marked as obsolete for
     years, and we still have WARN splats wrt races of the out-of-band
     /proc interface installed by this target.

   - Add 'destroy' commands to nf_tables. They are identical to the
     existing 'delete' commands, but do not return an error if the
     referenced object (set, chain, rule...) did not exist.

  Driver API:

   - Improve cpumask_local_spread() locality to help NICs set the right
     IRQ affinity on AMD platforms.

   - Separate C22 and C45 MDIO bus transactions more clearly.

   - Introduce new DCB table to control DSCP rewrite on egress.

   - Support configuration of Physical Layer Collision Avoidance (PLCA)
     Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
     shared medium Ethernet.

   - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
     preemption of low priority frames by high priority frames.

   - Add support for controlling MACSec offload using netlink SET.

   - Rework devlink instance refcounts to allow registration and
     de-registration under the instance lock. Split the code into
     multiple files, drop some of the unnecessarily granular locks and
     factor out common parts of netlink operation handling.

   - Add TX frame aggregation parameters (for USB drivers).

   - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
     messages with notifications for debug.

   - Allow offloading of UDP NEW connections via act_ct.

   - Add support for per action HW stats in TC.

   - Support hardware miss to TC action (continue processing in SW from
     a specific point in the action chain).

   - Warn if old Wireless Extension user space interface is used with
     modern cfg80211/mac80211 drivers. Do not support Wireless
     Extensions for Wi-Fi 7 devices at all. Everyone should switch to
     using nl80211 interface instead.

   - Improve the CAN bit timing configuration. Use extack to return
     error messages directly to user space, update the SJW handling,
     including the definition of a new default value that will benefit
     CAN-FD controllers, by increasing their oscillator tolerance.

+# fedora:
+#
+#	$ sudo yum install postgresql postgresql-server qt-postgresql

+#	$ sudo su - postgres
+#	$ createuser -s <your user id here>    # Older versions may not support -s, in which case answer the prompt below:
+#	Shall the new role be a superuser? (y/n) y
+#	$ sudo yum install python-pyside
+#
+#	Alternately, to use Python3 and/or pyside 2, one of the following:
+#		$ sudo yum install python3-pyside
+#		$ pip install --user PySide2
+#		$ pip3 install --user PySide2

+#	pt_example=# select * from samples_view where id < 100;
+#	pt_example=# \d+
+#	pt_example=# \d+ samples_view

+#
+# An example of using the database is provided by the script
+# exported-sql-viewer.py.  Refer to that script for details.
+#
+# Tables:
+#
+#	The tables largely correspond to perf tools' data structures.  They are largely self-explanatory.
+#
+#	samples
+#
+#		'samples' is the main table. It represents what instruction was executing at a point in time
+#		when something (a selected event) happened.  The memory address is the instruction pointer or 'ip'.
+#
+#	calls
+#
+#		'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
+#		'calls' is only created when the 'calls' option to this script is specified.
+#
+#	call_paths
+#
+#		'call_paths' represents all the call stacks.  Each 'call' has an associated record in 'call_paths'.
+#		'calls_paths' is only created when the 'calls' option to this script is specified.
+#
+#	branch_types
+#
+#		'branch_types' provides descriptions for each type of branch.
+#
+#	comm_threads
+#
+#		'comm_threads' shows how 'comms' relates to 'threads'.
+#
+#	comms
+#
+#		'comms' contains a record for each 'comm' - the name given to the executable that is running.
+#
+#	dsos
+#
+#		'dsos' contains a record for each executable file or library.
+#
+#	machines
+#
+#		'machines' can be used to distinguish virtual machines if virtualization is supported.
+#
+#	selected_events
+#
+#		'selected_events' contains a record for each kind of event that has been sampled.
+#
+#	symbols
+#
+#		'symbols' contains a record for each symbol.  Only symbols that have samples are present.
+#
+#	threads
+#
+#		'threads' contains a record for each thread.
+#
+# Views:
+#
+#	Most of the tables have views for more friendly display.  The views are:
+#
+#		calls_view
+#		call_paths_view
+#		comm_threads_view
+#		dsos_view
+#		machines_view
+#		samples_view
+#		symbols_view
+#		threads_view
+#
+# More examples of browsing the database with psql:
+#   Note that some of the examples are not the most optimal SQL query.
+#   Note that call information is only available if the script's 'calls' option has been used.
+#
+#	Top 10 function calls (not aggregated by symbol):
+#
+#		SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
+#
+#	Top 10 function calls (aggregated by symbol):
+#
+#		SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
+#			SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
+#			FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
+#
+#		Note that the branch count gives a rough estimation of cpu usage, so functions
+#		that took a long time but have a relatively low branch count must have spent time
+#		waiting.
+#
+#	Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
+#
+#		SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
+#
+#	Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
+#
+#		SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
+#
+#	Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
+#
+#		SELECT * FROM calls_view WHERE parent_call_path_id = 254;
+#
+#	Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
+#
+#		SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
+#
+#	Show transactions:
+#
+#		SELECT * FROM samples_view WHERE event = 'transactions';
+#
+#		Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
+#		Transaction aborts have branch_type_name 'transaction abort'
+#
+#	Show transaction aborts:
+#
+#		SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
+#
+# To print a call stack requires walking the call_paths table.  For example this python script:
+#   #!/usr/bin/python2
+#
+#   import sys
+#   from PySide.QtSql import *
