Nikolay Aleksandrov says: ==================== net: bridge: mcast: dump querier state This set adds the ability to dump the current multicast querier state. This is extremely useful when debugging multicast issues, we've had many cases of unexpected queriers causing strange behaviour and mcast test failures. The first patch changes the querier struct to record a port device's ifindex instead of a pointer to the port itself so we can later retrieve it, I chose this way because it's much simpler and doesn't require us to do querier port ref counting, it is best effort anyway. Then patch 02 makes the querier address/port updates consistent via a combination of multicast_lock and seqcount, so readers can only use seqcount to get a consistent snapshot of address and port. Patch 03 is a minor cleanup in preparation for the dump support, it consolidates IPv4 and IPv6 querier selection paths as they share most of the logic (except address comparisons of course). Finally the last three patches add the new querier state dumping support, for the bridge's global multicast context we embed the BRIDGE_QUERIER_xxx attributes into IFLA_BR_MCAST_QUERIER_STATE and for the per-vlan global mcast contexts we embed them into BRIDGE_VLANDB_GOPTS_MCAST_QUERIER_STATE. The structure is: [IFLA_BR_MCAST_QUERIER_STATE / BRIDGE_VLANDB_GOPTS_MCAST_QUERIER_STATE] `[BRIDGE_QUERIER_IP_ADDRESS] - ip address of the querier `[BRIDGE_QUERIER_IP_PORT] - bridge port ifindex where the querier was seen (set only if external querier) `[BRIDGE_QUERIER_IP_OTHER_TIMER] - other querier timeout `[BRIDGE_QUERIER_IPV6_ADDRESS] - ip address of the querier `[BRIDGE_QUERIER_IPV6_PORT] - bridge port ifindex where the querier was seen (set only if external querier) `[BRIDGE_QUERIER_IPV6_OTHER_TIMER] - other querier timeout Later we can also add IGMP version of seen queriers and last seen values from the queries. ==================== -

Add support for dumping global IPv6 querier state, we dump the state only if our own querier is enabled or there has been another external querier which has won the election. For the bridge global state we use a new attribute IFLA_BR_MCAST_QUERIER_STATE and embed the state inside. The structure is: [IFLA_BR_MCAST_QUERIER_STATE] `[BRIDGE_QUERIER_IPV6_ADDRESS] - ip address of the querier `[BRIDGE_QUERIER_IPV6_PORT] - bridge port ifindex where the querier was seen (set only if external querier) `[BRIDGE_QUERIER_IPV6_OTHER_TIMER] - other querier timeout IPv4 and IPv6 attributes are embedded at the same level of IFLA_BR_MCAST_QUERIER_STATE. If we didn't dump anything we cancel the nest and return. Signed-off-by: -

Use a sequence counter to make sure port/address updates can be read consistently without requiring the bridge multicast_lock. We need to zero out the port and address when the other querier has expired and we're about to select ourselves as querier. br_multicast_read_querier will be used later when dumping querier state. Updates are done only with the multicast spinlock and softirqs disabled, while reads are done from process context and from softirqs (due to notifications). Signed-off-by:

Currently when a querier port is detected its net_bridge_port pointer is recorded, but it's used only for comparisons so it's fine to have stale pointer, in order to dereference and use the port pointer a proper accounting of its usage must be implemented adding unnecessary complexity. To solve the problem we can just store the netdevice ifindex instead of the port pointer and retrieve the bridge port. It is a best effort and the device needs to be validated that is still part of that bridge before use, but that is small price to pay for avoiding querier reference counting for each port/vlan.

Leon Romanovsky says: ==================== Devlink cleanup for delay event series Jakub's request to make sure that devlink events are delayed and not printed till they fully accessible [1] requires us to implement delayed event notification system in the devlink. In order to do it, I moved some of my patches (xarray e.t.c) from the future series to be before "Move devlink_register to be near devlink_reload_enable" [2]. That allows us to rely on DEVLINK_REGISTERED xarray mark to decide if to print event or not. Other patches are simple cleanup which is needed anyway.

Leon Romanovsky authored
The struct devlink itself is protected by internal lock and doesn't need global lock during operation. That global lock is used to protect addition/removal new devlink instances from the global list in use by all devlink consumers in the system. The future conversion of linked list to be xarray will allow us to actually delete that lock, but first we need to count all struct devlink users. The reference counting provides us a way to ensure that no new user space commands success to grab devlink instance which is going to be destroyed makes it is safe to access it without lock.

Mat Martineau says: ==================== mptcp: Improve use of backup subflows Multipath TCP combines multiple TCP subflows in to one stream, and the MPTCP-level socket must decide which subflow to use when sending (or resending) chunks of data. The choice of the "best" subflow to transmit on can vary depending on the priority (normal or backup) for each subflow and how well the subflow is performing. In order to improve MPTCP performance when some subflows are failing, this patch set changes how backup subflows are utilized and introduces tracking of "stale" subflows that are still connected but not making progress. Patch 1 adjusts MPTCP-level retransmit timeouts to use data from all subflows. Patch 2 makes MPTCP-level retransmissions less aggressive to avoid resending data that's still queued at the TCP level. Patch 3 changes the way pending data is handled when subflows are closed. Unacked MPTCP-level data still in the subflow tx queue is immediately moved to another subflow for transmission instead of waiting for MPTCP-level timeouts to trigger retransmission. Patch 4 has some sysctl code cleanup. Patches 5 and 6 add tracking of "stale" subflows, so only underlying TCP subflow connections that appear to be making progress are considered when selecting a subflow to (re)transmit data. How fast a subflow goes stale is configurable with a per-namespace sysctl. Related MIBS are added too. Patch 7 makes sure the backup flag is always correctly recorded when the MP_JOIN SYN/ACK is received for an added subflow. Patch 8 adds more test cases for backup subflows and stale subflows. ==================== Signed-off-by: -

Paolo Abeni authored
The msk can use backup subflows to transmit in-sequence data only if there are no other active subflow. On active backup scenario, the MPTCP connection can do forward progress only due to MPTCP retransmissions - rtx can pick backup subflows. This patch introduces a new flag flow MPTCP subflows: if the underlying TCP connection made no progresses for long time, and there are other less problematic subflows available, the given subflow become stale. Stale subflows are not considered active: if all non backup subflows become stale, the MPTCP scheduler can pick backup subflows for plain transmissions. Stale subflows can return in active state, as soon as any reply from the peer is observed. Active backup scenarios can now leverage the available b/w with no restrinction.

Paolo Abeni authored
The PM can close active subflow, e.g. due to ingress RM_ADDR option. Such subflow could carry data still unacked at the MPTCP-level, both in the write and the rtx_queue, which has never reached the other peer. Currently the mptcp-level retransmission will deliver such data, but at a very low rate (at most 1 DSM for each MPTCP rtx interval). We can speed-up the recovery a lot, moving all the unacked in the tcp write_queue, so that it will be pushed again via other subflows, at the speed allowed by them. Also make available the new helper for later patches. Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/207Signed-off-by:

The current mptcp re-inject strategy is very aggressive, we have mptcp-level retransmissions even on single subflow connection, if the link in-use is lossy. Let's be a little more conservative: we do retransmit only if at least a subflow has write and rtx queue empty. Additionally use the backup subflows only if the active subflows are stale - no progresses in at least an rtx period and ignore stale subflows for rtx timeout update Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/207Signed-off-by:

As reported by Maxim, we have a lot of MPTCP-level retransmissions when multilple links with different latencies are in use. This patch refactor the mptcp-level timeout accounting so that the maximum of all the active subflow timeout is used. To avoid traversing the subflow list multiple times, the update is performed inside the packet scheduler. Additionally clean-up a bit timeout handling. Signed-off-by:

The 'imply' keyword does not do what most people think it does, it only politely asks Kconfig to turn on another symbol, but does not prevent it from being disabled manually or built as a loadable module when the user is built-in. In the ICE driver, the latter now causes a link failure: aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl': ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config' ice_main.c:(.text+0x13b0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_get_ts_config' aarch64-linux-ld: ice_main.c:(.text+0x13bc): undefined reference to `ice_ptp_set_ts_config' ice_main.c:(.text+0x13bc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_set_ts_config' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_prepare_for_reset': ice_main.c:(.text+0x31fc): undefined reference to `ice_ptp_release' ice_main.c:(.text+0x31fc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_release' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild': This is a recurring problem in many drivers, and we have discussed it several times befores, without reaching a consensus. I'm providing a link to the previous email thread for reference, which discusses some related problems. To solve the dependency issue better than the 'imply' keyword, introduce a separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver can depend on if it is able to use PTP support when available, but works fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are then prevented from being built-in, the same way as with a 'depends on PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick, but that can be rather confusing when you first see it. Since this should cover the dependencies correctly, the IS_REACHABLE() hack in the header is no longer needed now, and can be turned back into a normal IS_ENABLED() check. Any driver that gets the dependency wrong will now cause a link time failure rather than being unable to use PTP support when that is in a loadable module. However, the two recently added ptp_get_vclocks_index() and ptp_convert_timestamp() interfaces are only called from builtin code with ethtool and socket timestamps, so keep the current behavior by stubbing those out completely when PTP is in a loadable module. This should be addressed properly in a follow-up. As Richard suggested, we may want to actually turn PTP support into a 'bool' option later on, preventing it from being a loadable module altogether, which would be one way to solve the problem with the ethtool interface.

The EtherAVB instances on the R-Car E3/D3 and RZ/G2E SoCs do not support TX clock internal delay modes, and the EtherAVB driver prints a warning if an unsupported "rgmii-*id" PHY mode is specified, to catch buggy DTBs. Commit a6f51f2e ("ravb: Add support for explicit internal clock delay configuration") deprecated deriving the internal delay mode from the PHY mode, in favor of explicit configuration using the now mandatory "rx-internal-delay-ps" and "tx-internal-delay-ps" properties, thus delegating the warning to the legacy fallback code. Since explicit configuration of a (valid) internal clock delay configuration is enforced by validating device tree source files against DT binding files, and all upstream DTS files have been converted as of commit a5200e63 ("arm64: dts: renesas: rzg2: Convert EtherAVB to explicit delay handling"), the checks in the legacy fallback code can be removed.
