Use ULP to associate a subflow_context structure with each TCP subflow socket. Creating these sockets requires new bind and connect functions to make sure ULP is set up immediately when the subflow sockets are created. Co-developed-by:

Add hooks to parse and format the MP_CAPABLE option. This option is handled according to MPTCP version 0 (RFC6824). MPTCP version 1 MP_CAPABLE (RFC6824bis/RFC8684) will be added later in coordination with related code changes. Co-developed-by:

Implements the infrastructure for MPTCP sockets. MPTCP sockets open one in-kernel TCP socket per subflow. These subflow sockets are only managed by the MPTCP socket that owns them and are not visible from userspace. This commit allows a userspace program to open an MPTCP socket with: sock = socket(AF_INET, SOCK_STREAM, IPPROTO_MPTCP); The resulting socket is simply a wrapper around a single regular TCP socket, without any of the MPTCP protocol implemented over the wire.

Nikolay Aleksandrov says: ==================== net: bridge: add per-vlan state option This set adds the first per-vlan option - state, which uses the new vlan infrastructure that was recently added. It gives us forwarding control on per-vlan basis. The first 3 patches prepare the vlan code to support option dumping and modification. We still compress vlan ranges which have equal options, each new option will have to add its own equality check to br_vlan_opts_eq(). The vlans are created in forwarding state by default to be backwards compatible and vlan state is considered only when the port state is forwarding (more info in patch 4). I'll send the selftest for the vlan state with the iproute2 patch-set. v2: patch 3: do full (all-vlan) notification only on vlan create/delete, otherwise use the per-vlan notifications only, rework how option change ranges are detected, add more verbose error messages when setting options and add checks if a vlan should be used. ==================== Signed-off-by: -

The first per-vlan option added is state, it is needed for EVPN and for per-vlan STP. The state allows to control the forwarding on per-vlan basis. The vlan state is considered only if the port state is forwarding in order to avoid conflicts and be consistent. br_allowed_egress is called only when the state is forwarding, but the ingress case is a bit more complicated due to the fact that we may have the transition between port:BR_STATE_FORWARDING -> vlan:BR_STATE_LEARNING which should still allow the bridge to learn from the packet after vlan filtering and it will be dropped after that. Also to optimize the pvid state check we keep a copy in the vlan group to avoid one lookup. The state members are modified with *_ONCE() to annotate the lockless access. Signed-off-by:

This patch adds support for option modification of single vlans and ranges. It allows to only modify options, i.e. skip create/delete by using the BRIDGE_VLAN_INFO_ONLY_OPTS flag. When working with a range option changes we try to pack the notifications as much as possible. v2: do full port (all vlans) notification only when creating/deleting vlans for compatibility, rework the range detection when changing options, add more verbose extack errors and check if a vlan should be used (br_vlan_should_use checks) Signed-off-by: -
Nikolay Aleksandrov authored
We'll be dumping the options for the whole range if they're equal. The first range vlan will be used to extract the options. The commit doesn't change anything yet it just adds the skeleton for the support. The dump will happen when the first option is added. Signed-off-by:

If we make sure that br_allowed_egress is called only when we have BR_STATE_FORWARDING state then we can avoid a test later when we add per-vlan state. Signed-off-by:

Gautam Ramakrishnan says: ==================== net: sched: add Flow Queue PIE packet scheduler Flow Queue PIE packet scheduler This patch series implements the Flow Queue Proportional Integral controller Enhanced (FQ-PIE) active queue Management algorithm. It is an enhancement over the PIE algorithm. It integrates the PIE aqm with a deficit round robin scheme. FQ-PIE is implemented over the latest version of PIE which uses timestamps to calculate queue delay with an additional option of using average dequeue rate to calculate the queue delay. This patch also adds a memory limit of all the packets across all queues to a default value of 32Mb. - Patch #1 - Creates pie.h and moves all small functions and structures common to PIE and FQ-PIE here. The functions are all made inline. - Patch #2 - #8 - Addresses code formatting, indentation, comment changes and rearrangement of structure members. - Patch #9 - Refactors sch_pie.c by changing arguments to calculate_probability(), [pie_]drop_early() and pie_process_dequeue() to make it generic enough to be used by sch_fq_pie.c. These functions are exported to be used by sch_fq_pie.c. - Patch #10 - Adds the FQ-PIE Qdisc. For more information: https://tools.ietf.org/html/rfc8033 Changes from v6 to v7 - Call tcf_block_put() when destroying the Qdisc as suggested by Jakub Kicinski. Changes from v5 to v6 - Rearranged struct members according to their access pattern and to remove holes. Changes from v4 to v5 - This patch series breaks down patch 1 of v4 into separate logical commits as suggested by David Miller. Changes from v3 to v4 - Used non deprecated version of nla_parse_nested - Used SZ_32M macro - Removed an unused variable - Code cleanup All suggested by Jakub and Toke. Changes from v2 to v3 - Exported drop_early, pie_process_dequeue and calculate_probability functions from sch_pie as suggested by Stephen Hemminger. Changes from v1 ( and RFC patch) to v2 - Added timestamp to calculate queue delay as recommended by Dave Taht - Packet memory limit implemented as recommended by Toke. - Added external classifier as recommended by Toke. - Used NET_XMIT_CN instead of NET_XMIT_DROP as the return value in the fq_pie_qdisc_enqueue function. ==================== Signed-off-by: -

Principles: - Packets are classified on flows. - This is a Stochastic model (as we use a hash, several flows might be hashed to the same slot) - Each flow has a PIE managed queue. - Flows are linked onto two (Round Robin) lists, so that new flows have priority on old ones. - For a given flow, packets are not reordered. - Drops during enqueue only. - ECN capability is off by default. - ECN threshold (if ECN is enabled) is at 10% by default. - Uses timestamps to calculate queue delay by default. Usage: tc qdisc ... fq_pie [ limit PACKETS ] [ flows NUMBER ] [ target TIME ] [ tupdate TIME ] [ alpha NUMBER ] [ beta NUMBER ] [ quantum BYTES ] [ memory_limit BYTES ] [ ecnprob PERCENTAGE ] [ [no]ecn ] [ [no]bytemode ] [ [no_]dq_rate_estimator ] defaults: limit: 10240 packets, flows: 1024 target: 15 ms, tupdate: 15 ms (in jiffies) alpha: 1/8, beta : 5/4 quantum: device MTU, memory_limit: 32 Mb ecnprob: 10%, ecn: off bytemode: off, dq_rate_estimator: off Signed-off-by:Mohit P.

This patch makes the drop_early(), calculate_probability() and pie_process_dequeue() functions generic enough to be used by both PIE and FQ-PIE (to be added in a future commit). The major change here is in the way the functions take in arguments. This patch exports these functions and makes FQ-PIE dependent on sch_pie. Signed-off-by:

Fix punctuation and logical mistakes in the comments. The logical mistake was that "dequeue_rate" is no longer the default way to calculate queuing delay and is not needed.

In order to support all of the supported stats that are available in legacy mode for switchdev uplink representors, convert rep stats infrastructure to reuse struct mlx5e_stats_grp that is already used when device is in legacy mode. Refactor rep code to use array of mlx5e_stats_grp structures (constructed using macros provided by stats infra) to fill/update stats, instead of fixed hardcoded set of values. This approach allows to easily extend representors with new stats types. Signed-off-by:

In the flowtables offload all the devices in the flowtables share the same flow_block. An offload rule will be installed on all the devices. This scenario is not correct. It is no problem if there are only two devices in the flowtable, The rule with ingress and egress on the same device can be reject by driver. But more than two devices in the flowtable will install the wrong rules on hardware. For example: Three devices in a offload flowtables: dev_a, dev_b, dev_c A rule ingress from dev_a and egress to dev_b: The rule will install on device dev_a. The rule will try to install on dev_b but failed for ingress and egress on the same device. The rule will install on dev_c. This is not correct. The flowtables offload avoid this case through restricting the ingress dev with FLOW_DISSECTOR_KEY_META. So the mlx5e driver also should support the FLOW_DISSECTOR_KEY_META parse. Signed-off-by:
