Based on commit 64f2525c ("igb: Only DMA sync frame length") On some architectures synching a buffer for DMA may be expensive. Instead of the entire 2K receive buffer only synchronize the length of the frame, which will typically be the MTU or smaller.

Message sends to the local broadcast address (255.255.255.255) require uc_index or sk_bound_dev_if to be set to an egress device. However, responses or only received if the socket is bound to the device. This is overly constraining for processes running in an L3 domain. This patch allows a socket bound to the VRF device to send to the local broadcast address by using IP_UNICAST_IF to set the egress interface with packet receipt handled by the VRF binding. Similar to IP_MULTICAST_IF, relax the constraint on setting IP_UNICAST_IF if a socket is bound to an L3 master device. In this case allow uc_index to be set to an enslaved if sk_bound_dev_if is an L3 master device and is the master device for the ifindex. In udp and raw sendmsg, allow uc_index to override the oif if uc_index master device is oif (ie., the oif is an L3 master and the index is an L3 slave).

William Tu says: ==================== net: erspan: add support for openvswitch The first patch refactors the erspan header definitions. Originally, the erspan fields are defined as a group into a __be16 field, and use mask and offset to access each field. This is more costly due to calling ntohs/htons and error-prone. The first patch changes it to use bitfields. The second patch creates erspan.h in UAPI and move the definition 'struct erspan_metadata' to it for later openvswitch to use. The final patch introduces the new OVS tunnel key attribute, OVS_TUNNEL_KEY_ATTR_ERSPAN_OPTS, to program both v1 and v2 erspan tunnel for openvswitch. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

William Tu authored
The patch adds support for openvswitch to configure erspan v1 and v2. The OVS_TUNNEL_KEY_ATTR_ERSPAN_OPTS attr is added to uapi as a binary blob to support all ERSPAN v1 and v2's fields. Note that Previous commit "openvswitch: Add erspan tunnel support." was reverted since it does not design properly.

Jakub Kicinski says: ==================== use tc_cls_can_offload_and_chain0() throughout the drivers This set makes all drivers use a new tc_cls_can_offload_and_chain0() helper which will set extack in case TC hw offload flag is disabled. I chose to keep the new helper which also looks at the chain but renamed it more appropriately. The rationale being that most drivers don't accept chains other than 0 and since we have to pass extack to the helper we can as well pass the entire struct tc_cls_common_offload and perform the most common checks. This code makes the assumption that type_data in the callback can be interpreted as struct tc_cls_common_offload, i.e. the real offload structure has common part as the first member. This allows us to make the check once for all classifier types if driver supports more than one. v1: - drop the type validation in nfp and netdevsim. v2: - reorder checks in patch 1; - split other changes from patch 1; - add the i40e patch in; - add one more test case - for chain 0 extack. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Very few (mlxsw) upstream drivers seem to allow offload of chains other than 0. Save driver developers typing and add a helper for checking both if ethtool's TC offload flag is on and if chain is 0. This helper will set the extack appropriately in both error cases.

A state transition from closing state SMC_PEERFINCLOSEWAIT to closing state SMC_APPFINCLOSEWAIT is not allowed. Once a closing indication from the peer has been received, the socket reaches state SMC_CLOSED. And receiving a peer_conn_abort just changes the state of the socket into one of the states SMC_PROCESSABORT or SMC_CLOSED; sending a peer_conn_abort occurs in smc_close_active() for state SMC_PROCESSABORT only.

Edward Cree says: ==================== sfc: support PTP on 8000 and X2000 series NICs Starting from the 8000-series (Medford 1), SFC NICs can timestamp TX packets sent through an ordinary DMA queue, rather than a special control-plane operation as in the 7000-series. Patches 2-8 implement support for this. The X2000-series (Medford 2) changes the format of timestamps, from seconds+ (2^27)ths to seconds + quarter nanoseconds, as well as changing the shift of the frequency adjustment for increased precision. Patches 9-12 implement support for these changes. Patch #1 is an unrelated fix for NAPI budget handling, needed in order for TX completion changes in the later patches to apply cleanly. ==================== Signed-off-by: David S.
