Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Large effort by Eric to lower rtnl_lock pressure and remove locks:

- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.

- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.

- Remove locks / serialization in the socket diag interface.

- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.

- Remove the dev_base_lock, depend on RCU where necessary.

- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.

- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.

- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.

- Support TCP_NOTSENT_LOWAT in MPTCP.

- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.

- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.

- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.

- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.

- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.

- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.

- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).

- Speed up scanning for expired routes by keeping a dedicated list.

- Speed up "generic" XDP by trying harder to avoid large allocations.

- Support attaching arbitrary metadata to netconsole messages.

Things we sprinkled into general kernel code:

- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).

- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).

Netfilter:

- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.

- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.

BPF:

- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.

- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.

- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.

- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.

- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.

- Add support for retrieval of cookies for perf/kprobe multi links.

- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.

- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.

Wireless:

- Add SPP (signaling and payload protected) AMSDU support.

- Support wider bandwidth OFDMA, as required for EHT operation.

Driver API:

- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.

- Define an API for querying per netdev queue statistics from
drivers.

- IPSec: account in global stats for fully offloaded sessions.

- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.

- Enable Rx hashing (RSS) on GTP protocol fields.

Misc:

- Improvements and refactoring all over networking selftests.

- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.

- Address all missing MODULE_DESCRIPTION() warnings in networking.

- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".

Merge patch series "can: esd: add support for esd GmbH PCIe/402 CAN interface"

Stefan Mätje <stefan.maetje@esd.eu> says:

The purpose of this patch is to introduce a new CAN driver to support
the esd GmbH 402 family of CAN interface boards. The hardware design
is based on a CAN controller implemented in a FPGA attached to a
PCIe link.

More information on these boards can be found following the links
included in the commit message.

This patch supports all boards but will operate the CAN-FD capable
boards only in Classic-CAN mode. The CAN-FD support will be added
when the initial patch has stabilized.

The patch is reuses the previous work of my former colleague:
Link: https://lore.kernel.org/linux-can/1426592308-23817-1-git-send-email-thomas.koerper@esd.eu

The patch is based on the linux-can-next main branch.

Changed in v11:
No functional, only editorial changes due to feedback on v10.
- Make lifetime of macros used for hardware timestamp calculation
very short by #undef-ing them after use.
- Fixed insertion order of new entry in MAINTAINERS file.

Changed in v10:
Most changes due to feedback by Vincent Mailhol
https://lore.kernel.org/linux-can/CAMZ6RqLOAC930GNOU+pWuoi6FgYwFOuFrSyAzVjvE2fuVgy8oA@mail.gmail.com
- Add support for ethtool operations by using default operations
provided by the can_dev module for drivers with hardware time
stamp support.
- Factor out core unregistration into pci402_unregister_core().
- Factor out getting next TX fifo index into acc_tx_fifo_next().
- Stop counting alloc_can_err_skb() failures in rx_dropped statistic.
- Add CAN_ERR_CNT flag in CAN error frames as needed.
- Rework function acc_reset_fpga(). To clear I^2C bus enable bit
is not necessary after FPGA reset.
- Simplify struct acc_bmmsg_rxtxdone layout.
- Additional non functional changes due to feedback by Vincent
- Some spelling corrections: ESDACC -> esdACC

Changes in v9:
- Fix returning success error code in case of allocation failure in
pci402_probe().

Changes in v8:
- Rebased to 6.6-rc2 on linux-can-next branch main

Changes in v7:
- Numerous changes. Find the quoted with inline comments about changes
below after the changes list. Stuff that I don't understand and
where I have questions is marked with ????.
Unfortunately I will be AFK till 28th of November.

Changes in v6:
- Fixed the statistic handling of RX overrun errors and increase
net_device_stats::rx_errors instead of net_device_stats::rx_dropped.
- Added a patch to not increase rx statistics when generating a CAN
rx error message frame as suggested on the linux-can list.
- Added a patch to not not increase rx_bytes statistics for RTR frames
as suggested on the linux-can list.

The last two patches change the statistics handling from the previous
style used in other drivers to the newly suggested one.

Changes in v5:
- Added the initialization for netdev::dev_port as it is implemented
for another CAN driver. See
https://lore.kernel.org/linux-can/20211026180553.1953189-1-mailhol.vincent@wanadoo.fr

Changes in v4:
- Fixed the build failure on ARCH=arm64 that was found by the Intel
kernel test robot. See
https://lore.kernel.org/linux-can/202109120608.7ZbQXkRh-lkp@intel.com

Removed error monitoring code that used GCC's built-in compiler
functions for atomic access (__sync_* functions). GCC versions
after 9 (tested with "gcc-10 (Ubuntu 10.3.0-1ubuntu1~20.04)")
don't implement the intrinsic atomic as in-line code but call
"__aarch64_ldadd4_acq_rel" on arm64. This GCC support function
is not exported by the kernel and therefore the module build
post-processing fails.

Removed that code because the error monitoring never showed a
problem during the development this year.

Changes in v3:
- Rework the bus-off restart logic in acc_set_mode() and
handle_core_msg_errstatechange() to call netif_wake_queue() from the
error active event.
- Changed pci402_init_card() to allocate a variable sized array of
struct acc_core using devm_kcalloc() instead of using a fixed size
array in struct pci402_card.
- Changed handle_core_msg_txabort() to release aborted TX frames in
TX FIFO order.
- Fixed the acc_close() function to abort all pending TX request in
esdACC controller.
- Fixed counting of transmit aborts in handle_core_msg_txabort().
It is now done like in can_flush_echo_skb().
- Fixed handle_core_msg_buserr() to create error frames including the
CAN RX and TX error counters that were missing.
- Fixed acc_set_bittiming() neither to touch LOM mode setting of
esdACC controller nor to enter or leave RESET mode.
The esdACC controller is going active on the CAN bus in acc_open()
and is going inactive (RESET mode) again in acc_close().
- Rely on the automatic release of memory fetched by devm_kzalloc().
But still use devm_irq_free() explicitely to make sure that the
interrupt handler is disconnected at that point.
This avoids a possible crash in non-MSI mode due to the IRQ
triggered by another device on the same PCI IRQ line.
- Changed to use DMA map API instead of pci_*_consistent compatibility
wrappers.
- Fixed stale email references and updated copyright information.
- Removed any traces of future CAN-FD support.

Changes in v2:
- Avoid warning triggered by -Wshift-count-overflow on architectures
with 32-bit dma_addr_t.
- Fixed Makefile not to build the kernel module always. Doing this
renamed esd402_pci.c to esd_402_pci-core.c as recommended by Marc.

can: esd: add support for esd GmbH PCIe/402 CAN interface family

This patch adds support for the PCI based PCIe/402 CAN interface family
from esd GmbH that is available with various form factors
(https://esd.eu/en/products/402-series-can-interfaces).

All boards utilize a FPGA based CAN controller solution developed
by esd (esdACC). For more information on the esdACC see
https://esd.eu/en/products/esdacc.

This driver detects all available CAN interface board variants of
the family but atm. operates the CAN-FD capable devices in
Classic-CAN mode only! A later patch will introduce the CAN-FD
functionality in this driver.
