====================
pull-request: can-next 2022-07-03

this is a pull request of 15 patches for net-next/master.

The first 2 patches are by Max Staudt and add the can327 serial CAN
driver along with a new line discipline ID.

The next patch is by me an fixes a typo in the ctucanfd driver.

The last 12 patches are by Dario Binacchi and integrate slcan CAN
serial driver better into the existing CAN driver API.

Merge branch 'can-slcan-extend-supported-features'

Dario Binacchi says:
====================
This series originated as a result of CAN communication tests for an
application using the USBtin adapter (https://www.fischl.de/usbtin/).
The tests showed some errors but for the driver everything was ok.
Also, being the first time I used the slcan driver, I was amazed that
it was not possible to configure the bitrate via the ip tool.
For these two reasons, I started looking at the driver code and realized
that it didn't use the CAN network device driver interface.

Starting from these assumptions, I tried to:
- Use the CAN network device driver interface.
- Set the bitrate via the ip tool.
- Send the open/close command to the adapter from the driver.
- Add ethtool support to reset the adapter errors.
- Extend the protocol to forward the adapter CAN communication
errors and the CAN state changes to the netdev upper layers.

Except for the protocol extension patches (i. e. forward the adapter CAN
communication errors and the CAN state changes to the netdev upper
layers), the whole series has been tested under QEMU with Linux 4.19.208
using the USBtin adapter.
Testing the extension protocol patches requires updating the adapter
firmware. Before modifying the firmware I think it makes sense to know if
these extensions can be considered useful.

Before applying the series I used these commands:

slcan_attach -f -s6 -o /dev/ttyACM0
slcand ttyACM0 can0
ip link set can0 up

After applying the series I am using these commands:

slcan_attach /dev/ttyACM0
slcand ttyACM0 can0
ip link set dev can0 down
ip link set can0 type can bitrate 500000
ethtool --set-priv-flags can0 err-rst-on-open on
ip link set dev can0 up

Now there is a clearer separation between serial line and CAN,
but above all, it is possible to use the ip and ethtool commands
as it happens for any CAN device driver. The changes are backward
compatible, you can continue to use the slcand and slcan_attach
command options.

Changes in v5:
- Update the commit message.
- Restore the use of rtnl_lock() and rtnl_unlock().

Changes in v4:
- Move the patch in front of the patch "[v3,04/13] can: slcan: use CAN network device driver API".
- Add the CAN_BITRATE_UNSET (0) and CAN_BITRATE_UNKNOWN (-1U) macros.
- Simplify the bitrate check to dump it.
- Update the commit description.
- Update the commit description.
- Use the CAN_BITRATE_UNKNOWN macro.
- Use kfree_skb() instead of can_put_echo_skb() in the slc_xmit().
- Remove the `if (slcan_devs)' check in the slc_dealloc().
- Replace `sl->tty == NULL' with `!sl->tty'.
- Use CAN_BITRATE_UNSET (0) and CAN_BITRATE_UNKNOWN (-1U) macros.
- Don't reset the bitrate in ndo_stop() if it has been configured.
- Squashed to the patch [v3,09/13] can: slcan: send the close command to the adapter.
- Use the CAN_BITRATE_UNKNOWN macro.
- Add description of slc_bump_err() function.
- Remove check for the 'e' character at the beggining of the function.
It was already checked by the caller function.
- Protect decoding against the case the len value is longer than the
received data.
- Some small changes to make the decoding more readable.
- Increment all the error counters at the end of the function.
- Add description of slc_bump_state() function.
- Remove check for the 's' character at the beggining of the function.
It was already checked by the caller function.
- Protect decoding against the case the frame len is longer than the
received data (add SLC_STATE_FRAME_LEN macro).
- Set cf to NULL in case of alloc_can_err_skb() failure.
- Some small changes to make the decoding more readable.
- Use the character 'b' instead of 'f' for bus-off state.

Changes in v3:
- Increment the error counter in case of decoding failure.
- Replace (-1) with (-1U) in the commit description.
- Update the commit description.
- Remove the slc_do_set_bittiming().
- Set the bitrate in the ndo_open().
- Replace -1UL with -1U in setting a fake value for the bitrate.
- Drop the patch "can: slcan: simplify the device de-allocation".
- Add the patch "can: netlink: dump bitrate 0 if can_priv::bittiming.bitrate is -1U".

Changes in v2:
- Put the data into the allocated skb directly instead of first
filling the "cf" on the stack and then doing a memcpy().
- Move CAN_SLCAN Kconfig option inside CAN_DEV scope.
- Improve the commit message.
- Use the CAN framework support for setting fixed bit rates.
- Improve the commit message.
- Protect decoding against the case the len value is longer than the
received data.
- Continue error handling even if no skb can be allocated.
- Continue error handling even if no skb can be allocated.

Merge tag 'net-next-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core
----

- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.

- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).

- Continue work annotating skb drop reasons.

- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.

- Add VLAN support for AF_PACKET SOCK_RAW GSO.

- Allow receiving skb mark from the socket as a cmsg.

- Enable memcg accounting for veth queues, sysctl tables and IPv6.

BPF
---

- Add libbpf support for User Statically-Defined Tracing (USDTs).

- Speed up symbol resolution for kprobes multi-link attachments.

- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.

- Add support for BPF link iterator.

- Introduce access to remote CPU map elements in BPF per-cpu map.

- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.

- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.

Protocols
---------

- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding to
very popular ports (e.g. 443).

- Add bridge FDB bulk flush filtering support allowing user space to
remove all FDB entries matching a condition.

- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.

- Support for MPTCP path manager in user space.

- Add MPTCP support for fallback to regular TCP for connections that
have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).

- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.

- Support lockless operation of GRE tunnels with seq numbers enabled.

- WiFi support for host based BSS color collision detection.

- Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

====================
pull-request: can-next 2022-04-19

this is a pull request of 17 patches for net-next/master.

The first 2 patches are by me and target the CAN driver
infrastructure. One patch renames a function in the rx_offload helper
the other one updates the CAN bitrate calculation to prefer small bit
rate pre-scalers over larger ones, which is encouraged by the CAN in
Automation.

Kris Bahnsen contributes a patch to fix the links to Technologic
Systems web resources in the sja1000 driver.

Christophe Leroy's patch prepares the mpc5xxx_can driver for upcoming
powerpc header cleanup.

Minghao Chi's patch converts the flexcan driver to use
pm_runtime_resume_and_get().

The next 2 patches target the Xilinx CAN driver. Lukas Bulwahn's patch
fixes an entry in the MAINTAINERS file. A patch by me marks the bit
timing constants as const.

Wolfram Sang's patch documents r8a77961 support on the
renesas,rcar-canfd bindings document.

The next 2 patches are by me and add support for the mcp251863 chip to
the mcp251xfd driver.

The last 7 patches are by Pavel Pisa, Martin Jerabek et al. and add
the ctucanfd driver for the CTU CAN FD IP Core.
