The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here). This also fixes !CONFIG_OF error: drivers/ptp/ptp_ines.c:783:34: error: ‘ines_ptp_ctrl_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by:

Currently, kernel would set MSG_CTRUNC flag if msg_control buffer wasn't provided and SO_PASSCRED was set or if there was pending SCM_RIGHTS. For some reason we have no corresponding check for SO_PASSSEC. In the recvmsg(2) doc we have: MSG_CTRUNC indicates that some control data was discarded due to lack of space in the buffer for ancillary data. So, we need to set MSG_CTRUNC flag for all types of SCM. This change can break applications those don't check MSG_CTRUNC flag. Cc: "David S.

It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

Tony Nguyen says: ==================== i40e: support XDP multi-buffer Tirthendu Sarkar says: This patchset adds multi-buffer support for XDP. Tx side already has support for multi-buffer. This patchset focuses on Rx side. The last patch contains actual multi-buffer changes while the previous ones are preparatory patches. On receiving the first buffer of a packet, xdp_buff is built and its subsequent buffers are added to it as frags. While 'next_to_clean' keeps pointing to the first descriptor, the newly introduced 'next_to_process' keeps track of every descriptor for the packet. On receiving EOP buffer the XDP program is called and appropriate action is taken (building skb for XDP_PASS, reusing page for XDP_DROP, adjusting page offsets for XDP_{REDIRECT,TX}). The patchset also streamlines page offset adjustments for buffer reuse to make it easier to post process the rx_buffers after running XDP prog. With this patchset there does not seem to be any performance degradation for XDP_PASS and some improvement (~1% for XDP_TX, ~5% for XDP_DROP) when measured using xdp_rxq_info program from samples/bpf/ for 64B packets. v1: https://lore.kernel.org/netdev/20230306210822.3381942-1-anthony.l.nguyen@intel.com/ * '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: i40e: add support for XDP multi-buffer Rx i40e: add xdp_buff to i40e_ring struct i40e: introduce next_to_process to i40e_ring i40e: use frame_sz instead of recalculating truesize for building skb i40e: Change size to truesize when using i40e_rx_buffer_flip() i40e: add pre-xdp page_count in rx_buffer i40e: change Rx buffer size for legacy-rx to support XDP multi-buffer i40e: consolidate maximum frame size calculation for vsi ==================== Link: https://lore.kernel.org/r/20230309212819.1198218-1-anthony.l.nguyen@intel.comSigned-off-by:

Virtio spec introduced a feature VIRTIO_NET_F_GUEST_HDRLEN which when set implicates that device benefits from knowing the exact size of the header. For compatibility, to signal to the device that the header is reliable driver also needs to set this feature. Without this feature set by driver, device has to figure out the header size itself. Quoting the original virtio spec: "hdr_len is a hint to the device as to how much of the header needs to be kept to copy into each packet" "a hint" might not be clear for the reader what does it mean, if it is "maybe like that" of "exactly like that". This feature just makes it crystal clear and let the device count on the hdr_len being filled up by the exact length of header. Also note the spec already has following note about hdr_len: "Due to various bugs in implementations, this field is not useful as a guarantee of the transport header size." Without this feature the device needs to parse the header in core data path handling. Accurate information helps the device to eliminate such header parsing and directly use the hardware accelerators for GSO operation. virtio_net_hdr_from_skb() fills up hdr_len to skb_headlen(skb). The driver already complies to fill the correct value. Introduce the feature and advertise it. Note that virtio spec also includes following note for device implementation: "Caution should be taken by the implementation so as to prevent a malicious driver from attacking the device by setting an incorrect hdr_len." There is a plan to support this feature in our emulated device. A device of SolidRun offers this feature bit. They claim this feature will save the device a few cycles for every GSO packet.

If no frames has been exchanged with a node for HSR_NODE_FORGET_TIME, the node will be deleted from the node_db list. If a frame is sent to the node after it is deleted, a netdev_err message for each slave interface is produced. This should not happen with dan nodes because of supervision frames, but can happen often with san nodes, which clutters the kernel log. Since the hsr protocol does not support sans, this is only relevant for the prp protocol. Signed-off-by:
