Adding bridge multicast context support for host-joined groups is easy because we only need the proper timer value. We pass the already chosen context and use its timer value. Signed-off-by:

Choose the proper bridge multicast context when user-spaces is adding mdb entries. Currently we require the vlan to be configured on at least one device (port or bridge) in order to add an mdb entry if vlan mcast snooping is enabled (vlan snooping implies vlan filtering). Note that we always allow deleting an entry, regardless of the vlan state. Signed-off-by:

This patch improves the yaml a bit according to Rob Herring comments: 1) normalize interrupt-names property, there is no reason to support random order. 2) validate each string in clock-names property. 3) add constraints for fsl,num-tx-queues/fsl,num-rx-queues property. 4) change additionalProperties to false in order to do strict checking.

tcp_grow_window() is using skb->len/skb->truesize to increase tp->rcv_ssthresh which has a direct impact on advertized window sizes. We added TCP coalescing in linux-3.4 & linux-3.5: Instead of storing skbs with one or two MSS in receive queue (or OFO queue), we try to append segments together to reduce memory overhead. High performance network drivers tend to cook skb with 3 parts : 1) sk_buff structure (256 bytes) 2) skb->head contains room to copy headers as needed, and skb_shared_info 3) page fragment(s) containing the ~1514 bytes frame (or more depending on MTU) Once coalesced into a previous skb, 1) and 2) are freed. We can therefore tweak the way we compute len/truesize ratio knowing that skb->truesize is inflated by 1) and 2) soon to be freed. This is done only for in-order skb, or skb coalesced into OFO queue. The result is that low rate flows no longer pay the memory price of having low GRO aggregation factor. Same result for drivers not using GRO. This is critical to allow a big enough receiver window, typically tcp_rmem[2] / 2. We have been using this at Google for about 5 years, it is due time to make it upstream. Signed-off-by:

With the recent change to use bridge/port multicast context pointers instead of bridge/port I missed to convert two locations which pass the port pointer as-is, but with the new model we need to verify the port context is non-NULL first and retrieve the port from it. The first location is when doing querier selection when a query is received, the second location is when leaving a group. The port context will be null if the packets originated from the bridge device (i.e. from the host). The fix is simple just check if the port context exists and retrieve the port pointer from it.

Justin Iurman says: ==================== Support for the IOAM Pre-allocated Trace with IPv6 v5: - Refine types, min/max and default values for new sysctls - Introduce a "_wide" sysctl for each "ioam6_id" sysctl - Add more validation on headers before processing data - RCU for sc <> ns pointers + appropriate accessors - Generic Netlink policies are now per op, not per family anymore - Address other comments/remarks from Jakub (thanks again) - Revert "__packed" to "__attribute__((packed))" for uapi headers - Add tests to cover the functionality added, as requested by David Ahern v4: - Address warnings from checkpatch (ignore errors related to unnamed bitfields in the first patch) - Use of hweight32 (thanks Jakub) - Remove inline keyword from static functions in C files and let the compiler decide what to do (thanks Jakub) v3: - Fix warning "unused label 'out_unregister_genl'" by adding conditional macro - Fix lwtunnel output redirect bug: dst cache useless in this case, use orig_output instead v2: - Fix warning with static for __ioam6_fill_trace_data - Fix sparse warning with __force when casting __be64 to __be32 - Fix unchecked dereference when removing IOAM namespaces or schemas - exthdrs.c: Don't drop by default (now: ignore) to match the act bits "00" - Add control plane support for the inline insertion (lwtunnel) - Provide uapi structures - Use __net_timestamp if skb->tstamp is empty - Add note about the temporary IANA allocation - Remove support for "removable" TLVs - Remove support for virtual/anonymous tunnel decapsulation In-situ Operations, Administration, and Maintenance (IOAM) records operational and telemetry information in a packet while it traverses a path between two points in an IOAM domain. It is defined in draft-ietf-ippm-ioam-data [1]. IOAM data fields can be encapsulated into a variety of protocols. The IPv6 encapsulation is defined in draft-ietf-ippm-ioam-ipv6-options [2], via extension headers. IOAM can be used to complement OAM mechanisms based on e.g. ICMP or other types of probe packets. This patchset implements support for the Pre-allocated Trace, carried by a Hop-by-Hop. Therefore, a new IPv6 Hop-by-Hop TLV option is introduced, see IANA [3]. The three other IOAM options are not included in this patchset (Incremental Trace, Proof-of-Transit and Edge-to-Edge). The main idea behind the IOAM Pre-allocated Trace is that a node pre-allocates some room in packets for IOAM data. Then, each IOAM node on the path will insert its data. There exist several interesting use- cases, e.g. Fast failure detection/isolation or Smart service selection. Another killer use-case is what we have called Cross-Layer Telemetry, see the demo video on its repository [4], that aims to make the entire stack (L2/L3 -> L7) visible for distributed tracing tools (e.g. Jaeger), instead of the current L5 -> L7 limited view. So, basically, this is a nice feature for the Linux Kernel. This patchset also provides support for the control plane part, but only for the inline insertion (host-to-host use case), through lightweight tunnels. Indeed, for in-transit traffic, the solution is to have an IPv6-in-IPv6 encapsulation, which brings some difficulties and still requires a little bit of work and discussion (ie anonymous tunnel decapsulation and multi egress resolution). - Patch 1: IPv6 IOAM headers definition - Patch 2: Data plane support for Pre-allocated Trace - Patch 3: IOAM Generic Netlink API - Patch 4: Support for IOAM injection with lwtunnels - Patch 5: Documentation for new IOAM sysctls - Patch 6: Test for the IOAM insertion with IPv6 [1] https://tools.ietf.org/html/draft-ietf-ippm-ioam-data [2] https://tools.ietf.org/html/draft-ietf-ippm-ioam-ipv6-options [3] https://www.iana.org/assignments/ipv6-parameters/ipv6-parameters.xhtml#ipv6-parameters-2 [4] https://github.com/iurmanj/cross-layer-telemetry ==================== Signed-off-by:

This test evaluates the IOAM insertion for IPv6 by checking the IOAM data integrity on the receiver. The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between) and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only, which means not on the reverse path. When Gamma is the destination, Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM data integrity is checked on Gamma, by comparing with the pre-defined IOAM configuration (see below). +-------------------+ +-------------------+ | | | | | alpha netns | | gamma netns | | | | | | +-------------+ | | +-------------+ | | | veth0 | | | | veth0 | | | | db01::2/64 | | | | db02::2/64 | | | +-------------+ | | +-------------+ | | . | | . | +-------------------+ +-------------------+ . . . . . . +----------------------------------------------------+ | . . | | +-------------+ +-------------+ | | | veth0 | | veth1 | | | | db01::1/64 | ................ | db02::1/64 | | | +-------------+ +-------------+ | | | | beta netns | | | +--------------------------+-------------------------+ ~~~~~~~~~~~~~~~~~~~~~~ | IOAM configuration | ~~~~~~~~~~~~~~~~~~~~~~ Alpha +-----------------------------------------------------------+ | Type | Value | +-----------------------------------------------------------+ | Node ID | 1 | +-----------------------------------------------------------+ | Node Wide ID | 11111111 | +-----------------------------------------------------------+ | Ingress ID | 0xffff (default value) | +-----------------------------------------------------------+ | Ingress Wide ID | 0xffffffff (default value) | +-----------------------------------------------------------+ | Egress ID | 101 | +-----------------------------------------------------------+ | Egress Wide ID | 101101 | +-----------------------------------------------------------+ | Namespace Data | 0xdeadbee0 | +-----------------------------------------------------------+ | Namespace Wide Data | 0xcafec0caf00dc0de | +-----------------------------------------------------------+ | Schema ID | 777 | +-----------------------------------------------------------+ | Schema Data | something that will be 4n-aligned | +-----------------------------------------------------------+ Note: When Gamma is the destination, Alpha adds an IOAM Pre-allocated Trace option inside a Hop-by-hop, where 164 bytes are pre-allocated for the trace, with 123 as the IOAM-Namespace and with 0xfff00200 as the trace type (= all available options at this time). As a result, and based on IOAM configurations here, only both Alpha and Beta should be capable of inserting their IOAM data while Gamma won't have enough space and will set the overflow bit.

Add documentation for new IOAM sysctls: - ioam6_id and ioam6_id_wide: two per-namespace sysctls - ioam6_enabled, ioam6_id and ioam6_id_wide: three per-interface sysctls Example of IOAM configuration based on the following simple topology: _____ _____ _____ | | eth0 eth0 | | eth1 eth0 | | | A |.----------.| B |.----------.| C | |_____| |_____| |_____| 1) Node and interface IDs can be configured for IOAM: # IOAM ID of A = 1, IOAM ID of A.eth0 = 11 (A) sysctl -w net.ipv6.ioam6_id=1 (A) sysctl -w net.ipv6.conf.eth0.ioam6_id=11 # IOAM ID of B = 2, IOAM ID of B.eth0 = 21, IOAM ID of B.eth1 = 22 (B) sysctl -w net.ipv6.ioam6_id=2 (B) sysctl -w net.ipv6.conf.eth0.ioam6_id=21 (B) sysctl -w net.ipv6.conf.eth1.ioam6_id=22 # IOAM ID of C = 3, IOAM ID of C.eth0 = 31 (C) sysctl -w net.ipv6.ioam6_id=3 (C) sysctl -w net.ipv6.conf.eth0.ioam6_id=31 Note that "_wide" IDs equivalents can be configured the same way. 2) Each node can be configured to form an IOAM domain. For instance, we allow IOAM from A to C only (not the reverse path), i.e. enable IOAM on ingress for B.eth0 and C.eth0: (B) sysctl -w net.ipv6.conf.eth0.ioam6_enabled=1 (C) sysctl -w net.ipv6.conf.eth0.ioam6_enabled=1 3) An IOAM domain (e.g. ID=123) is defined and made known to each node: (A) ip ioam namespace add 123 (B) ip ioam namespace add 123 (C) ip ioam namespace add 123 4) Finally, an IOAM Pre-allocated Trace can be inserted in traffic sent by A when C (e.g. db02::2) is the destination: (A) ip -6 route add db02::2/128 encap ioam6 trace type 0x800000 ns 123 size 12 dev eth0 Signed-off-by: -

Add support for the IOAM inline insertion (only for the host-to-host use case) which is per-route configured with lightweight tunnels. The target is iproute2 and the patch is ready. It will be posted as soon as this patchset is merged. Here is an overview: $ ip -6 ro ad fc00::1/128 encap ioam6 trace type 0x800000 ns 1 size 12 dev eth0 This example configures an IOAM Pre-allocated Trace option attached to the fc00::1/128 prefix. The IOAM namespace (ns) is 1, the size of the pre-allocated trace data block is 12 octets (size) and only the first IOAM data (bit 0: hop_limit + node id) is included in the trace (type) represented as a bitfield. The reason why the in-transit (IPv6-in-IPv6 encapsulation) use case is not implemented is explained on the patchset cover. Signed-off-by:

Implement support for processing the IOAM Pre-allocated Trace with IPv6, see [1] and [2]. Introduce a new IPv6 Hop-by-Hop TLV option, see IANA [3]. A new per-interface sysctl is introduced. The value is a boolean to accept (=1) or ignore (=0, by default) IPv6 IOAM options on ingress for an interface: - net.ipv6.conf.XXX.ioam6_enabled Two other sysctls are introduced to define IOAM IDs, represented by an integer. They are respectively per-namespace and per-interface: - net.ipv6.ioam6_id - net.ipv6.conf.XXX.ioam6_id The value of the first one represents the IOAM ID of the node itself (u32; max and default value = U32_MAX>>8, due to hop limit concatenation) while the other represents the IOAM ID of an interface (u16; max and default value = U16_MAX). Each "ioam6_id" sysctl has a "_wide" equivalent: - net.ipv6.ioam6_id_wide - net.ipv6.conf.XXX.ioam6_id_wide The value of the first one represents the wide IOAM ID of the node itself (u64; max and default value = U64_MAX>>8, due to hop limit concatenation) while the other represents the wide IOAM ID of an interface (u32; max and default value = U32_MAX). The use of short and wide equivalents is not exclusive, a deployment could choose to leverage both. For example, net.ipv6.conf.XXX.ioam6_id (short format) could be an identifier for a physical interface, whereas net.ipv6.conf.XXX.ioam6_id_wide (wide format) could be an identifier for a logical sub-interface. Documentation about new sysctls is provided at the end of this patchset. Two relativistic hash tables are used: one for IOAM namespaces, the other for IOAM schemas. A namespace can only have a single active schema and a schema can only be attached to a single namespace (1:1 relationship).

This patch provides the IPv6 IOAM option header [1] as well as the IOAM Trace header [2]. An IOAM option must be 4n-aligned.

The IOAM Trace header starts at "Namespace-ID" and ends after "IOAM-Trace-Type/Reserved". IOAM Type: either Pre-allocated Trace (=0), Incremental Trace (=1), Proof-of-Transit (=2) or Edge-to-Edge (=3). Note that both the Pre-allocated Trace and the Incremental Trace look the same. The two others are not implemented. Namespace-ID: IOAM namespace identifier, not to be confused with network namespaces. It adds further context to IOAM options and associated data, and allows devices which are IOAM capable to determine whether IOAM options must be processed or ignored. It can also be used by an operator to distinguish different operational domains or to identify different sets of devices. NodeLen: Length of data added by each node. It depends on the Trace Type. Flags: Only the Overflow (O) flag for now. The O flag is set by a transit node when there are not enough octets left to record its data. RemainingLen: Remaining free space to record data. IOAM-Trace-Type: Bit field where each bit corresponds to a specific kind of IOAM data. See [2] for a detailed list.

The difference between __switchdev_handle_fdb_del_to_device and switchdev_handle_del_to_device is that the former takes an extra orig_dev argument, while the latter starts with dev == orig_dev. We should recurse into the variant that does not lose the orig_dev along the way. This is relevant when deleting FDB entries pointing towards a bridge (dev changes to the lower interfaces, but orig_dev shouldn't). The addition helper already recurses properly, just the deletion one doesn't. Fixes: 8ca07176 ("net: switchdev: introduce a fanout helper for SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE") Signed-off-by:

As the cycle time is set to maximum of 1s, the TX Hang timeout need to be increase to avoid possible TX Hang. There is no dedicated number specific in data sheet for the timeout factor. Timeout factor was determined during the debugging to solve the "Tx Hang" issues that happen in some cases mainly during ETF(Earliest TxTime First). This can be test by using TSN Schedule Tx Tools udp_tai sample application. Signed-off-by:

i225 devices have only one phy->type: copper. There is no point checking phy->type during the igc_has_link method from the watchdog that invoked every 2 seconds. This patch comes to clean up these pointless checkings. Signed-off-by:

Ensure that the adapter->q_vector[MAX_Q_VECTORS] array isn't accessed beyond its size. It was fixed by using a local variable num_q_vectors as a limit for loop index, and ensure that num_q_vectors is not bigger than MAX_Q_VECTORS. Suggested-by:

Per guidance from the CSME architecture team, it may take up to 1 second for unconfiguring dynamic power gating mode. Practically it can take more time. Wait up to 2.5 seconds to indicate dynamic power gating exit from the S0ix configuration. Detect scenarios that take more than 1 second but less than 2.5 seconds will emit warning message.
