Mubashir Adnan Qureshi says: ==================== net: Add PLB functionality to TCP This patch series adds PLB (Protective Load Balancing) to TCP and hooks it up to DCTCP. PLB is disabled by default and can be enabled using relevant sysctls and support from underlying CC. PLB (Protective Load Balancing) is a host based mechanism for load balancing across switch links. It leverages congestion signals(e.g. ECN) from transport layer to randomly change the path of the connection experiencing congestion. PLB changes the path of the connection by changing the outgoing IPv6 flow label for IPv6 connections (implemented in Linux by calling sk_rethink_txhash()). Because of this implementation mechanism, PLB can currently only work for IPv6 traffic.

A u32 counter is added to tcp_sock for counting the number of PLB triggered rehashes for a TCP connection. An SNMP counter is also added to count overall PLB triggered rehash events for a host. These counters are hooked up to PLB implementation for DCTCP. TCP_NLA_REHASH is added to SCM_TIMESTAMPING_OPT_STATS that reports the rehash attempts triggered due to PLB or timeouts. This gives a historical view of sustained congestion or timeouts experienced by the TCP connection. Signed-off-by:

Mubashir Adnan Qureshi authored
Congestion control algorithms track PLB state and cause the connection to trigger a path change when either of the 2 conditions is satisfied: - No packets are in flight and (# consecutive congested rounds >= sysctl_tcp_plb_idle_rehash_rounds) - (# consecutive congested rounds >= sysctl_tcp_plb_rehash_rounds) A round (RTT) is marked as congested when congestion signal (ECN ce_ratio) over an RTT is greater than sysctl_tcp_plb_cong_thresh. In the event of RTO, PLB (via tcp_write_timeout()) triggers a path change and disables congestion-triggered path changes for random time between (sysctl_tcp_plb_suspend_rto_sec, 2*sysctl_tcp_plb_suspend_rto_sec) to avoid hopping onto the "connectivity blackhole". RTO-triggered path changes can still happen during this cool-off period. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next 1) Move struct nft_payload_set definition to .c file where it is only used. 2) Shrink transport and inner header offset fields in the nft_pktinfo structure to 16-bits, from Florian Westphal. 3) Get rid of nft_objref Kbuild toggle, make it built-in into nf_tables. This expression is used to instantiate conntrack helpers in nftables. After removing the conntrack helper auto-assignment toggle it this feature became more important so move it to the nf_tables core module. Also from Florian. 4) Extend the existing function to calculate payload inner header offset to deal with the GRE and IPIP transport protocols. 6) Add inner expression support for nf_tables. This new expression provides a packet parser for tunneled packets which uses a userspace description of the expected inner headers. The inner expression invokes the payload expression (via direct call) to match on the inner header protocol fields using the inner link, network and transport header offsets. An example of the bytecode generated from userspace to match on IP source encapsulated in a VxLAN packet: # nft --debug=netlink add rule netdev x y udp dport 4789 vxlan ip saddr 1.2.3.4 netdev x y [ meta load l4proto => reg 1 ] [ cmp eq reg 1 0x00000011 ] [ payload load 2b @ transport header + 2 => reg 1 ] [ cmp eq reg 1 0x0000b512 ] [ inner type vxlan hdrsize 8 flags f [ meta load protocol => reg 1 ] ] [ cmp eq reg 1 0x00000008 ] [ inner type vxlan hdrsize 8 flags f [ payload load 4b @ network header + 12 => reg 1 ] ] [ cmp eq reg 1 0x04030201 ] 7) Store inner link, network and transport header offsets in percpu area to parse inner packet header once only. Matching on a different tunnel type invalidates existing offsets in the percpu area and it invokes the inner tunnel parser again. 8) Add support for inner meta matching. This support for NFTA_META_PROTOCOL, which specifies the inner ethertype, and NFT_META_L4PROTO, which specifies the inner transport protocol. 9) Extend nft_inner to parse GENEVE optional fields to calculate the link layer offset. 10) Update inner expression so tunnel offset points to GRE header to normalize tunnel header handling. This also allows to perform different interpretations of the GRE header from userspace. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next: netfilter: nft_inner: set tunnel offset to GRE header offset netfilter: nft_inner: add geneve support netfilter: nft_meta: add inner match support netfilter: nft_inner: add percpu inner context netfilter: nft_inner: support for inner tunnel header matching netfilter: nft_payload: access ipip payload for inner offset netfilter: nft_payload: access GRE payload via inner offset netfilter: nft_objref: make it builtin netfilter: nf_tables: reduce nft_pktinfo by 8 bytes netfilter: nft_payload: move struct nft_payload_set definition where it belongs ==================== Link: https://lore.kernel.org/r/20221026132227.3287-1-pablo@netfilter.org Signed-off-by:Jakub Kicinski <kuba@kernel.org>

Under memory pressure, enetc_refill_rx_ring() may fail, and when called during the enetc_open() -> enetc_setup_rxbdr() procedure, this is not checked for. An extreme case of memory pressure will result in exactly zero buffers being allocated for the RX ring, and in such a case it is expected that hardware drops all RX packets due to lack of buffers. This does not happen, because the reset-default value of the consumer and produces index is 0, and this makes the ENETC think that all buffers have been initialized and that it owns them (when in reality none were). The hardware guide explains this best: | Configure the receive ring producer index register RBaPIR with a value | of 0. The producer index is initially configured by software but owned | by hardware after the ring has been enabled. Hardware increments the | index when a frame is received which may consume one or more BDs. | Hardware is not allowed to increment the producer index to match the | consumer index since it is used to indicate an empty condition. The ring | can hold at most RBLENR[LENGTH]-1 received BDs. | | Configure the receive ring consumer index register RBaCIR. The | consumer index is owned by software and updated during operation of the | of the BD ring by software, to indicate that any receive data occupied | in the BD has been processed and it has been prepared for new data. | - If consumer index and producer index are initialized to the same | value, it indicates that all BDs in the ring have been prepared and | hardware owns all of the entries. | - If consumer index is initialized to producer index plus N, it would | indicate N BDs have been prepared. Note that hardware cannot start if | only a single buffer is prepared due to the restrictions described in | (2). | - Software may write consumer index to match producer index anytime | while the ring is operational to indicate all received BDs prior have | been processed and new BDs prepared for hardware. Normally, the value of rx_ring->rcir (consumer index) is brought in sync with the rx_ring->next_to_use software index, but this only happens if page allocation ever succeeded. When PI==CI==0, the hardware appears to receive frames and write them to DMA address 0x0 (?!), then set the READY bit in the BD. The enetc_clean_rx_ring() function (and its XDP derivative) is naturally not prepared to handle such a condition. It will attempt to process those frames using the rx_swbd structure associated with index i of the RX ring, but that structure is not fully initialized (enetc_new_page() does all of that). So what happens next is undefined behavior. To operate using no buffer, we must initialize the CI to PI + 1, which will block the hardware from advancing the CI any further, and drop everything. The issue was seen while adding support for zero-copy AF_XDP sockets, where buffer memory comes from user space, which can even decide to supply no buffers at all (example: "xdpsock --txonly"). However, the bug is present also with the network stack code, even though it would take a very determined person to trigger a page allocation failure at the perfect time (a series of ifup/ifdown under memory pressure should eventually reproduce it given enough retries).

When setting Bluefield to DPU NIC mode using mlxconfig tool + sync firmware reset flow, we run into scenario where the host was not eswitch manager at the time of mlx5 driver load but becomes eswitch manager after the sync firmware reset flow. This results in null pointer access of mpfs structure during mac filter add. This change prevents null pointer access but mpfs table entries will not be added.

Update devlink health fw fatal reporter state to "healthy" is needed by strictly calling devlink_health_reporter_state_update() after recovery was done by PCI error handler. This is needed when fw_fatal reporter was triggered due to PCI error. Poll health is called and set reporter state to error. Health recovery failed (since EEH didn't re-enable the PCI). PCI handlers keep on recover flow and succeed later without devlink acknowledgment. Fix this by adding devlink state update at the end of the PCI handler recovery process.

On multi table split the driver creates a new attr instance with data being copied from prev attr instance zeroing action flags. Also need to reset dests properties to avoid incorrect dests per attr. Fixes: 8300f225 ("net/mlx5e: Create new flow attr for multi table actions") Signed-off-by:

Reject TC rules that forward from internal port to internal port as it is not supported. This include rules that are explicitly have internal port as the filter device as well as rules that apply on tunnel interfaces as the route device for the tunnel interface can be an internal port.
