net: add netdev_lockdep_set_classes() to virtual drivers

[ Upstream commit 0bef512012b1cd8820f0c9ec80e5f8ceb43fdd59 ]

Based on a syzbot report, it appears many virtual
drivers do not yet use netdev

net: add netdev_lockdep_set_classes() to virtual drivers

[ Upstream commit 0bef512012b1cd8820f0c9ec80e5f8ceb43fdd59 ]

Based on a syzbot report, it appears many virtual
drivers do not yet use netdev_lockdep_set_classes(),
triggerring lockdep false positives.

Merge tag 'net-next-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core:

- Allow live renaming when an interface is up

- Add retpoline wrappers for tc, improving considerably the
performances of complex queue discipline configurations

- Add inet drop monitor support

- A few GRO performance improvements

- Add infrastructure for atomic dev stats, addressing long standing
data races

- De-duplicate common code between OVS and conntrack offloading
infrastructure

- A bunch of UBSAN_BOUNDS/FORTIFY_SOURCE improvements

- Replace IPVS timer-based estimators with kthreads to scale up the
workload with the number of available CPUs

- Add the helper support for connection-tracking OVS offload

BPF:

- Support for user defined BPF objects: the use case is to allocate
own objects, build own object hierarchies and use the building
blocks to build own data structures flexibly, for example, linked
lists in BPF

- Make cgroup local storage available to non-cgroup attached BPF
programs

- Avoid unnecessary deadlock detection and failures wrt BPF task
storage helpers

- A relevant bunch of BPF verifier fixes and improvements

- Veristat tool improvements to support custom filtering, sorting,
and replay of results

- Add LLVM disassembler as default library for dumping JITed code

- Lots of new BPF documentation for various BPF maps

- Add bpf_rcu_read_{,un}lock() support for sleepable programs

- Add RCU grace period chaining to BPF to wait for the completion of
access from both sleepable and non-sleepable BPF programs

- Add support storing struct task_struct objects as kptrs in maps

- Improve helper UAPI by explicitly defining BPF_FUNC_xxx integer
values

- Add libbpf *_opts API-variants for bpf_*_get_fd_by_id() functions

Protocols:

- TCP: implement Protective Load Balancing across switch links

- TCP: allow dynamically disabling TCP-MD5 static key, reverting back
to fast[er]-path

- Netlink: support different type policies for each generic netlink
operation

- MPTCP: add MSG_FASTOPEN and FastOpen listener side support

complete header processing and crypto offloading

- IPSec: extended ack support for more descriptive XFRM error
reporting

- RXRPC: increase SACK table size and move processing into a
per-local endpoint kernel thread, reducing considerably the
required locking

- IEEE 802154: synchronous send frame and extended filtering support,
initial support for scanning available 15.4 networks

- Tun: bump the link speed from 10Mbps to 10Gbps

- Tun/VirtioNet: implement UDP segmentation offload support

Driver API:

- PHY/SFP: improve power level switching between standard level 1 and
the higher power levels

- New API for netdev <-> devlink_port linkage

- PTP: convert existing drivers to new frequency adjustment
implementation

- DSA: add support for rx offloading

- Autoload DSA tagging driver when dynamically changing protocol

- Add new PCP and APPTRUST attributes to Data Center Bridging

ethtool: doc: clarify what drivers can implement in their get_drvinfo()

Many of the drivers which implement ethtool_ops::get_drvinfo() will
prints the .driver, .version or .bus_info of struct ethtool_drvinfo.
To have a glance of current state, do:

$ git grep -W "get_drvinfo(struct"

Printing in those three fields is useless because:

- since [1], the driver version should be the kernel version (at
least for upstream drivers). Arguably, out of tree drivers might
still want to set a custom version, but out of tree is not our
focus.

- since [2], the core is able to provide default values for .driver
and .bus_info.

In summary, drivers may provide .fw_version and .erom_version, the
rest is expected to be done by the core.

In struct ethtool_ops doc from linux/ethtool: rephrase field
get_drvinfo() doc to discourage developers from implementing this
callback.

In struct ethtool_drvinfo doc from uapi/linux/ethtool.h: remove the
paragraph mentioning what drivers should do. Rationale: no need to
repeat what is already written in struct ethtool_ops doc. But add a
note that .fw_version and .erom_version are driver defined.

Also update the dummy driver and simply remove the callback in order
not to confuse the newcomers: most of the drivers will not need this
callback function any more.

kernel version")

Merge tag 'net-next-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.

- Run packets which already went thru HW coalescing thru SW GRO. This
significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.

- Shrink the size of the base zero-copy send structure.

- Move TCP init under a new slow / sleepable version of DO_ONCE().

BPF:

- Add BPF-specific, any-context-safe memory allocator.

- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.

- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).

- Allow targeting BPF iterators to loop through resources of one
task/thread.

- Add ability to call selected destructive functions. Expose
crash_kexec() to allow BPF to trigger a kernel dump. Use
CAP_SYS_BOOT check on the loading process to judge permissions.

- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.

- Support struct arguments for trampoline based programs. Only
structs with size <= 16B and x86 are supported.

- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).

- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.

- Support accessing network tunnel metadata's flags.

- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.

- Add support for writing to Netfilter's nf_conn:mark.

Protocols:

- WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
(MLO) work (802.11be, WiFi 7).

- vsock: improve support for SO_RCVLOWAT.

- SMC: support SO_REUSEPORT.

- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.

- IPSec: support collect metadata mode for xfrm interfaces.

- TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
packets.

- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).

- MPTCP: support TCP_FASTOPEN_CONNECT.

- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.

- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.

- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.

- TLS: support the Korean ARIA-GCM crypto algorithm.

- Remove DECnet support.

Driver API:

- Allow selecting the conduit interface used by each port in DSA
switches, at runtime.

- Ethernet Power Sourcing Equipment and Power Device support.

- Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
traffic class max frame size for time-based packet schedules.

- Support PHY rate matching - adapting between differing host-side
and link-side speeds.

- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.

- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.

- Require that flash component name used during update matches one of
the components for which version is reported by info_get().

- Remove "weight" argument from driver-facing NAPI API as much as
possible. It's one of those magic knobs which seemed like a good
idea at the time but is too indirect to use in practice.

- Support offload of TLS connections with 256 bit keys.
