Add new nested netlink attribute to configure the MRP. These attributes are used by the userspace to add/delete/configure MRP instances and by the kernel to notify the userspace when the MRP ring gets open/closed. MRP nested attribute has the following attributes: IFLA_BRIDGE_MRP_INSTANCE - the parameter type is br_mrp_instance which contains the instance id, and the ifindex of the two ports. The ports can't be part of multiple instances. This is used to create/delete MRP instances. IFLA_BRIDGE_MRP_PORT_STATE - the parameter type is u32. Which can be forwarding, blocking or disabled. IFLA_BRIDGE_MRP_PORT_ROLE - the parameter type is br_mrp_port_role which contains the instance id and the role. The role can be primary or secondary. IFLA_BRIDGE_MRP_RING_STATE - the parameter type is br_mrp_ring_state which contains the instance id and the state. The state can be open or closed. IFLA_BRIDGE_MRP_RING_ROLE - the parameter type is br_mrp_ring_role which contains the instance id and the ring role. The role can be MRM or MRC. IFLA_BRIDGE_MRP_START_TEST - the parameter type is br_mrp_start_test which contains the instance id, the interval at which to send the MRP_Test frames, how many test frames can be missed before declaring the ring open and the period which represent for how long to send the test frames. Also add the file include/uapi/linux/mrp_bridge.h which defines all the types used by MRP that are also needed by the userpace. Reviewed-by:

In MPTCP, the receive window is shared across all subflows, because it refers to the mptcp-level sequence space. MPTCP receivers already place incoming packets on the mptcp socket receive queue and will charge it to the mptcp socket rcvbuf until userspace consumes the data. Update __tcp_select_window to use the occupancy of the parent/mptcp socket instead of the subflow socket in case the tcp socket is part of a logical mptcp connection. This commit doesn't change choice of initial window for passive or active connections. While it would be possible to change those as well, this adds complexity (especially when handling MP_JOIN requests). Furthermore, the MPTCP RFC specifically says that a MPTCP sender 'MUST NOT use the RCV.WND field of a TCP segment at the connection level if it does not also carry a DSS option with a Data ACK field.' SYN/SYNACK packets do not carry a DSS option with a Data ACK field. Signed-off-by:

Huazhong Tan says: ==================== net: hns3: refactor for MAC table This patchset refactors the MAC table management, configure the MAC address asynchronously, instead of synchronously. Base on this change, it also refines the handle of promisc mode and filter table entries restoring after reset. ==================== Signed-off-by: -
Jian Shen authored
Currently, the PF driver removes all (including its VFs') MAC/VLAN flow director table entries when resetting, and restores them after reset completed. In fact, the hardware will clear all table entries only in IMP reset and global reset. So driver only needs to restore the table entries in these cases, and needs do nothing when PF reset, FLR or other function level reset. This patch optimizes it by removing unnecessary table entries clear and restoring handling in the reset flow, and doing the restoring after reset completed. Signed-off-by:

Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range. Signed-off-by:

As the HNS3 driver doesn't update the MAC address directly in function hns3_set_rx_mode() now, it can't know whether the MAC table is full from __dev_uc_sync() and __dev_mc_sync(), so it's senseless to handle the overflow promisc here. This patch removes the handle of overflow promisc from function hns3_set_rx_mode(), and updates the promisc mode in the service task. Signed-off-by:

Jian Shen authored
Currently, the HNS3 driver sync and unsync MAC address in function hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly in the path of dev_set_rx_mode(). If failed, it won't retry until next calling of hns3_set_rx_mode(). On the other hand, if request add and remove a same address many times at a short interval, each request must be done one by one, can't be merged. For VF, it sends mailbox messages to PF to request adding or deleting MAC address in the path of function hns3_set_rx_mode(), no matter the address is configured success. This patch refines it by recording the MAC address in function hns3_set_rx_mode(), and updating MAC address in the service task. If failed, it will retry by the next calling of periodical service task. It also uses some state to mark the state of each MAC address in the MAC list, which can help merge configure request for a same address. With these changes, when global reset or IMP reset occurs, we can restore the MAC table with the MAC list. Signed-off-by:

Jian Shen authored
Currently, firmware helps manage the unicast MAC VLAN table space for each PF. PF just needs to tell firmware its wanted space when initializing, and unnecessary to free it when un-intializing. So this patch removes the umv space free handle, and removes the forward statement of hclge_set_umv_space() by defining hclge_init_umv_space() after it. Signed-off-by:

Reorder include paths to ensure that runqslower sources are picking up vmlinux.h, generated by runqslower's own Makefile. When runqslower is built from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it might pick up not-yet-complete vmlinux.h, generated by selftests Makefile, which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT) goes first and rely on runqslower's Makefile own dependency chain to ensure vmlinux.h is properly completed before source code relying on it is compiled.
