Change steering flow to optimize traffic in promiscuous mode. On demand, add a high priority table containing a catch-all rule. All incoming packets are caught by this rule and steered directly to the TTC table. Prior to this change, packets in promiscuous mode may suffer from up to 4 steering hops before reaching TTC table. In addition, this patch will allow us adding a catch-all rule at the end of MAC table to serve MAC trap, with no impact on promiscuous mode performance. Signed-off-by:

Early generations of the mv88e6xxx did not have the global 2 registers. In order to keep the driver slim, it was decided to make the code for these registers optional. Over time, more generations of switches have been added, always supporting global 2 and adding more and more registers. No effort has been made to keep these additional registers also optional to slim the driver down when used for older generations. Optional global 2 now just gives additional development and maintenance burden for no real gain. Make global 2 support always compiled in. Signed-off-by:

The next patch is by Vincent Mailhol and targets the CAN driver infrastructure, it exports the function that converts the CAN state into a human readable string. A patch by me, which target the CAN driver infrastructure, too, makes the calculation in can_fd_len2dlc() more readable. A patch by Tom Rix fixes a checkpatch warning in the mcba_usb driver. The next seven patches target the mcp251xfd driver. Su Yanjun's patch replaces several hardcoded assumptions when calling regmap, by using regmap_get_val_bytes(). The remaining patches are by me. First an open coded check is replaced by an existing helper function, then in the TX path the padding for CAN-FD frames is cleaned up. The next two patches clean up the RTR frame handling in the RX and TX path. Then support for len8_dlc is added. The last patch adds BQL support. * tag 'linux-can-next-for-5.12-20210127' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next: can: mcp251xfd: add BQL support can: mcp251xfd: add len8_dlc support can: mcp251xfd: mcp251xfd_tx_obj_from_skb(): don't copy data for RTR CAN frames in TX-path can: mcp251xfd: mcp251xfd_hw_rx_obj_to_skb(): don't copy data for RTR CAN frames in RX-path can: mcp251xfd: mcp251xfd_tx_obj_from_skb(): clean up padding of CAN-FD frames can: mcp251xfd: mcp251xfd_start_xmit(): use mcp251xfd_get_tx_free() to check TX is is full can: mcp251xfd: replace sizeof(u32) with val_bytes in regmap can: mcba_usb: remove h from printk format specifier can: length: can_fd_len2dlc(): make legnth calculation readable again can: dev: export can_get_state_str() function can: flexcan: fix typos can: gw: fix typo ==================== Link: https://lore.kernel.org/r/20210127092227.2775573-1-mkl@pengutronix.deSigned-off-by:

Patch 01 adds a default limit of 512 tracked hosts per-port, since the EHT changes are still only in net-next that shouldn't be a problem. Then patch 02 adds the ability to configure and retrieve the hosts limit and to retrieve the current number of tracked hosts per port. Let's be on the safe side and limit the number of tracked hosts by default while allowing the user to increase that limit if needed. ==================== Link: https://lore.kernel.org/r/20210126093533.441338-1-razor@blackwall.orgSigned-off-by:

Mat Martineau says: ==================== MPTCP: IPv4-mapped IPv6 addressing for subflows This patch series from the MPTCP tree adds support for IPv4-mapped IPv6 addressing that was missing when multiple subflows were first implemented. Patches 1 and 2 handle the conversion and comparison of the mapped addresses. Patch 3 contains a minor refactor in the path manager's handling of addresses. Patches 4 and 5 add selftests for the new functionality and adjust the selftest timeout. ==================== Link: https://lore.kernel.org/r/20210125185904.6997-1-mathew.j.martineau@linux.intel.comSigned-off-by:

Here, we make sure we support IPv4-mapped in IPv6 addresses in different contexts: - a v4-mapped address is received by the PM and can be used as v4. - a v4 address is received by the PM and can be used even with a v4 mapped socket. We also make sure we don't try to establish subflows between v4 and v6 addresses, e.g. if a real v6 address ends with a valid v4 address. Co-developed-by:

On one side, we can allow the creation of subflows between v4 mapped in v6 and v4 addresses. For that we look for v4mapped addresses between the local address we want to select and the remote one. On the other side, we also properly deal with received v4mapped addresses, either announced ones or set via Netlink. Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/122Suggested-by:

Matthieu Baerts authored
With an IPv4 mapped in v6 socket, we were trying to call inet6_bind() with an IPv4 address resulting in a -EINVAL error because the given addr_len -- size of the address structure -- was too short. We now make sure to use address structures for the same family as the MPTCP socket for both the bind() and the connect(). It means we convert v4 addresses to v4 mapped in v6 or the opposite if needed. Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/122Co-developed-by:

pktgen create threads for all online cpus and bond these threads to relevant cpu repecivtily. when this thread firstly be woken up, it will compare cpu currently running with the cpu specified at the time of creation and if the two cpus are not equal, BUG_ON() will take effect causing panic on the system. Notice that these threads could be migrated to other cpus before start running because of the cpu hotplug after these threads have created. so the BUG_ON() used here seems unreasonable and we can replace it with WARN_ON() to just printf a warning other than panic the system.

Fix a regression where everything in virt_wifi would just hang. This happened due to overlapping changes between commit a05829a7 ("cfg80211: avoid holding the RTNL when calling the driver") which had originally needed to change the locking, but then I introduced commit 2fe8ef10 ("cfg80211: change netdev registration/unregistration semantics") instead. virt_wifi somehow fell through the cracks when I undid all the previous locking changes. Fix it now.

CAN-FD frames have only specific frame length (0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 20, 24, 32, 48, 64). A CAN-FD frame provided by user space might not cover the whole CAN-FD frame. To avoid sending garbage over the CAN bus the driver pads the CAN frame with 0x0 (if MCP251XFD_SANITIZE_CAN is activated). This patch cleans up the pad len calculation. Rounding to full u32 brings no benefit, in case of CRC transfers, the hw_tx_obj->data is not aligned to u32 anyway.
