Mat Martineau says: ==================== mptcp: Add genl events for connection info This series from the MPTCP tree adds genl multicast events that are important for implementing a userspace path manager. In MPTCP, a path manager is responsible for adding or removing additional subflows on each MPTCP connection. The in-kernel path manager (already part of the kernel) is a better fit for many server use cases, but the additional flexibility of userspace path managers is often useful for client devices. Patches 1, 2, 4, 5, and 6 do some refactoring to streamline the netlink event implementation in the final patch. Patch 3 improves the timeliness of subflow destruction to ensure the 'subflow closed' event will be sent soon enough. Patch 7 allows use of the GENL_UNS_ADMIN_PERM flag on genl mcast groups to mandate CAP_NET_ADMIN, which is important to protect token information in the MPTCP events. This is a genetlink change. Patch 8 adds the MPTCP netlink events. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Allow userspace (mptcpd) to subscribe to mptcp genl multicast events. This implementation reuses the same event API as the mptcp kernel fork to ease integration of existing tools, e.g. mptcpd. Supported events include: 1. start and close of an mptcp connection 2. start and close of subflows (joins) 3. announce and withdrawals of addresses 4. subflow priority (backup/non-backup) change.

When remote side closes a subflow we should schedule the worker to dispose of the subflow in a timely manner. Otherwise, SF_CLOSED event won't be generated until the mptcp socket itself is closing or local side is closing another subflow. Signed-off-by:

Prepare for subflow close events: When mptcp connection is torn down its enough to send the mptcp socket close notification rather than a subflow close event for all of the subflows followed by the mptcp close event. This splits the helper: mptcp_close_ssk() will emit the close notification, __mptcp_close_ssk will not. Signed-off-by:

Mat Martineau says: ==================== mptcp: Selftest enhancement and fixes This is a collection of selftest updates from the MPTCP tree. Patch 1 uses additional 'ss' command line parameters and 'nstat' to improve output when certain MPTCP tests fail. Patches 2 & 3 fix a copy/paste error and some output formatting. Patch 4 makes sure tests still pass if certain connection-related packets are retransmitted. ==================== Signed-off-by: -

If we receive less MPCapable SYN or 3rd ACK than expected, we now mark the test as failed. On the other hand, if we receive more, we keep the warning but we add a hint that it is probably due to retransmissions and that's why we don't mark the test as failed.

Before we had this in case of SYN retransmissions: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP ns2-60143c00-cDZWo4 SYNRX: MPTCP -> MPTCP: expect 11, got # 13 # (duration 6221ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) Now we have: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP (duration 6221ms) [ OK ] WARN: SYNRX: expect 11, got 13 # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) So we put everything on one line, keep the durations and "OK" aligned and removed duplicated info to short the warning. Signed-off-by:

Even if that may sound completely unlikely, the mptcp implementation is not perfect, yet. When the self-tests report an error we usually need more information of what the scripts currently report. iproute allow provides some additional goodies since a few releases, let's dump them. Signed-off-by:

Use a new config SOCK_RX_QUEUE_MAPPING to compile-in the socket RX queue field and logic, instead of the XPS config. This breaks dependency in XPS, and allows selecting it from non-XPS use cases, as we do in the next patch. In addition, use the new flag to wrap the logic in sk_rx_queue_get() and protect access to the sk_rx_queue_mapping field, while keeping the function exposed unconditionally, just like sk_rx_queue_set() and sk_rx_queue_clear().

dev_ifsioc_locked() is called with only RCU read lock, so when there is a parallel writer changing the mac address, it could get a partially updated mac address, as shown below: Thread 1 Thread 2 // eth_commit_mac_addr_change() memcpy(dev->dev_addr, addr->sa_data, ETH_ALEN); // dev_ifsioc_locked() memcpy(ifr->ifr_hwaddr.sa_data, dev->dev_addr,...); Close this race condition by guarding them with a RW semaphore, like netdev_get_name(). We can not use seqlock here as it does not allow blocking. The writers already take RTNL anyway, so this does not affect the slow path. To avoid bothering existing dev_set_mac_address() callers in drivers, introduce a new wrapper just for user-facing callers on ioctl and rtnetlink paths. Note, bonding also changes slave mac addresses but that requires a separate patch due to the complexity of bonding code. Fixes: 3710becf ("net: RCU locking for simple ioctl()") Reported-by:

J721e, J7200 and AM64 have multi port switches which can work in multi mac mode and in switch mode. Add support for configuring this HW in switch mode using devlink and switchdev notifiers. Support is similar to existing CPSW switchdev implementation of TI's 32 bit platform like AM33/AM43/AM57. To enable switch mode: devlink dev param set platform/8000000.ethernet name switch_mode value true cmode runtime All configuration is implemented via switchdev API and notifiers. Supported: - SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS - SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS - SWITCHDEV_ATTR_ID_PORT_STP_STATE - SWITCHDEV_OBJ_ID_PORT_VLAN - SWITCHDEV_OBJ_ID_PORT_MDB - SWITCHDEV_OBJ_ID_HOST_MDB Hence AM65 CPSW switchdev driver supports: - FDB offloading - MDB offloading - VLAN filtering and offloading - STP Signed-off-by: -

AM65 NUSS ethernet switch on K3 devices can be configured to work either in independent mac mode where each port acts as independent network interface (multi mac) or switch mode. Add devlink hooks to provide a way to switch b/w these modes. Rationale to use devlink instead of defaulting to bridge mode is that SoC use cases require to support multiple independent MAC ports with no switching so that users can use software bridges with multi-mac configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching between multi mac and switch mode requires significant Port and ALE reconfiguration, therefore is easier to be made as part of mode change devlink hooks. It also allows to keep user interface similar to what was implemented for the previous generation of TI CPSW IP (on AM33/AM43/AM57 SoCs). Signed-off-by:
