2024-03-27octeontx2: Detect the mbox up or down message via registerSubbaraya Sundeep3-65/+121
[ Upstream commit a88e0f936ba9a301c78f6eacfd38737d003c130b ] A single line of interrupt is used to receive up notifications and down reply messages from AF to PF (similarly from PF to its VF). PF acts as bridge and forwards VF messages to AF and sends respsones back from AF to VF. When an async event like link event is received by up message when PF is in middle of forwarding VF message then mailbox errors occur because PF state machine is corrupted. Since VF is a separate driver or VF driver can be in a VM it is not possible to serialize from the start of communication at VF. Hence to differentiate between type of messages at PF this patch makes sender to set mbox data register with distinct values for up and down messages. Sender also checks whether previous interrupt is received before triggering current interrupt by waiting for mailbox data register to become zero.

[ Upstream commit dbda436824ded8ef6a05bb82cd9baa8d42377a49 ] Current implementation is such that, promisc mcam entry action is set as multicast even when there are no trusted VFs. multicast action causes the hardware to copy packet data, which reduces the performance.

[ Upstream commit fd7f98b2e12a3d96a92bde6640657ec7116f4372 ] TC ingress policer rules depends on interface receive queue contexts since the bandwidth profiles are attached to RQ contexts. When an interface is brought down all the queue contexts are freed. This in turn frees bandwidth profiles in hardware causing ingress police rules non-functional after the interface is brought up. Fix this by applying all the ingress police rules config to hardware in otx2_open. Also allow adding ingress rules only when interface is running since no contexts exist for the interface when it is down.

2023-12-03octeontx2-pf: Fix ntuple rule creation to direct packet to VF with higher Rx ↵Suman Ghosh1-1/+19
queue than its PF [ Upstream commit 4aa1d8f89b10cdc25a231dabf808d8935e0b137a ] It is possible to add a ntuple rule which would like to direct packet to a VF whose number of queues are greater/less than its PF's queue numbers. For example a PF can have 2 Rx queues but a VF created on that PF can have 8 Rx queues. As of today, ntuple rule will reject rule because it is checking the requested queue number against PF's number of Rx queues. As a part of this fix if the action of a ntuple rule is to move a packet to a VF's queue then the check is removed. Also, a debug information is printed to aware user that it is user's responsibility to cross check if the requested queue number on that VF is a valid one.

2023-09-10octeontx2-pf: Fix page pool cache index corruption.Ratheesh Kannoth7-51/+44
The access to page pool `cache' array and the `count' variable is not locked. Page pool cache access is fine as long as there is only one consumer per pool. octeontx2 driver fills in rx buffers from page pool in NAPI context. If system is stressed and could not allocate buffers, refiiling work will be delegated to a delayed workqueue. This means that there are two cosumers to the page pool cache. Either workqueue or IRQ/NAPI can be run on other CPU. This will lead to lock less access, hence corruption of cache pool indexes. To fix this issue, NAPI is rescheduled from workqueue context to refill rx buffers.

2023-08-26cteonxt2-pf: Fix backpressure config for multiple PFC priorities to work ↵Suman Ghosh1-3/+3
simultaneously MAC (CGX or RPM) asserts backpressure at TL3 or TL2 node of the egress hierarchical scheduler tree depending on link level config done. If there are multiple PFC priorities enabled at a time and for all such flows to backoff, each priority will have to assert backpressure at different TL3/TL2 scheduler nodes and these flows will need to submit egress pkts to these nodes. Current PFC configuration has an issue where in only one backpressure scheduler node is being allocated which is resulting in only one PFC priority to work. This patch fixes this issue.

2023-08-25octeontx2-pf: fix page_pool creation fail for rings > 32kRatheesh Kannoth2-1/+3
octeontx2 driver calls page_pool_create() during driver probe() and fails if queue size > 32k. Page pool infra uses these buffers as shock absorbers for burst traffic. These pages are pinned down over time as working sets varies, due to the recycling nature of page pool, given page pool (currently) don't have a shrinker mechanism, the pages remain pinned down in ptr_ring. Instead of clamping page_pool size to 32k at most, limit it even more to 2k to avoid wasting memory. This have been tested on octeontx2 CN10KA hardware. TCP and UDP tests using iperf shows no performance regressions.

The latter will definitely require fixes but I think that we got it to a reasonable point. Core: - Rework the sendpage & splice implementations Instead of feeding data into sockets page by page extend sendmsg handlers to support taking a reference on the data, controlled by a new flag called MSG_SPLICE_PAGES Rework the handling of unexpected-end-of-file to invoke an additional callback instead of trying to predict what the right combination of MORE/NOTLAST flags is Remove the MSG_SENDPAGE_NOTLAST flag completely - Implement SCM_PIDFD, a new type of CMSG type analogous to SCM_CREDENTIALS, but it contains pidfd instead of plain pid - Enable socket busy polling with CONFIG_RT - Improve reliability and efficiency of reporting for ref_tracker - Auto-generate a user space C library for various Netlink families Protocols: - Allow TCP to shrink the advertised window when necessary, prevent sk_rcvbuf auto-tuning from growing the window all the way up to tcp_rmem[2] - Use per-VMA locking for "page-flipping" TCP receive zerocopy - Prepare TCP for device-to-device data transfers, by making sure that payloads are always attached to skbs as page frags - Make the backoff time for the first N TCP SYN retransmissions linear. Exponential backoff is unnecessarily conservative - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO) - Avoid waking up applications using TLS sockets until we have a full record - Allow using kernel memory for protocol ioctl callbacks, paving the way to issuing ioctls over io_uring - Add nolocalbypass option to VxLAN, forcing packets to be fully encapsulated even if they are destined for a local IP address - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure in-kernel ECMP implementation (e.g. Open vSwitch) select the same link for all packets. Support L4 symmetric hashing in Open vSwitch - PPPoE: make number of hash bits configurable - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client (ipconfig) - Add layer 2 miss indication and filtering, allowing higher layers (e.g. ACL filters) to make forwarding decisions based on whether packet matched forwarding state in lower devices (bridge) - Support matching on Connectivity Fault Management (CFM) packets - Hide the "link becomes ready" IPv6 messages by demoting their printk level to debug - HSR: don't enable promiscuous mode if device offloads the proto - Support active scanning in IEEE 802.15.4 - Continue work on Multi-Link Operation for WiFi 7 BPF: - Add precision propagation for subprogs and callbacks. This allows maintaining verification efficiency when subprograms are used, or in fact passing the verifier at all for complex programs, especially those using open-coded iterators - Improve BPF's {g,s}setsockopt() length handling. Previously BPF assumed the length is always equal to the amount of written data. But some protos allow passing a NULL buffer to discover what the output buffer *should* be, without writing anything - Accept dynptr memory as memory arguments passed to helpers - Add routing table ID to bpf_fib_lookup BPF helper - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark maps as read-only) - Show target_{obj,btf}_id in tracing link fdinfo - Addition of several new kfuncs (most of the names are self-explanatory): - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(), bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size() and bpf_dynptr_clone(). - bpf_task_under_cgroup() - bpf_sock_destroy() - force closing sockets - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs Netfilter: - Relax set/map validation checks in nf_tables.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull ordered workqueue creation updates from Tejun Heo: "For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time. This creates ambiguity around whether ordered execution is actually required for correctness, which was actually confusing for e.g. btrfs (btrfs updates are being routed through the btrfs tree). There aren't that many users in the tree which use the combination and there are pending improvements to unbound workqueue affinity handling which will make inadvertent use of ordered workqueue a bigger loss. This clarifies the situation for most of them by updating the ones which require ordered execution to use alloc_ordered_workqueue(). There are some conversions being routed through subsystem-specific trees and likely a few stragglers. Once they're all converted, workqueue can trigger a warning on unbound + @max_active==1 usages and eventually drop the implicit ordered behavior" * tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: rxrpc: Use alloc_ordered_workqueue() to create ordered workqueues net: qrtr: Use alloc_ordered_workqueue() to create ordered workqueues net: wwan: t7xx: Use alloc_ordered_workqueue() to create ordered workqueues dm integrity: Use alloc_ordered_workqueue() to create ordered workqueues media: amphion: Use alloc_ordered_workqueue() to create ordered workqueues scsi: NCR5380: Use default @max_active for hostdata->work_q media: coda: Use alloc_ordered_workqueue() to create ordered workqueues crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues wifi: ath10/11/12k: Use alloc_ordered_workqueue() to create ordered workqueues wifi: mwifiex: Use default @max_active for workqueues wifi: iwlwifi: Use default @max_active for trans_pcie->rba.alloc_wq xen/pvcalls: Use alloc_ordered_workqueue() to create ordered workqueues virt: acrn: Use alloc_ordered_workqueue() to create ordered workqueues net: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues net: thunderx: Use alloc_ordered_workqueue() to create ordered workqueues greybus: Use alloc_ordered_workqueue() to create ordered workqueues powerpc, workqueue: Use alloc_ordered_workqueue() to create ordered workqueues
2023-06-21octeontx2-pf: TC flower offload support for rxqueue mappingRatheesh Kannoth1-2/+12
TC rule support to offload rx queue mapping rules. Eg: tc filter add dev eth2 ingress protocol ip flower \ dst_ip 192.168.8.100 \ action skbedit queue_mapping 4 skip_sw action mirred ingress redirect dev eth5 Packets destined to 192.168.8.100 will be forwarded to rx queue 4 of eth5 interface. tc filter add dev eth2 ingress protocol ip flower \ dst_ip 192.168.8.100 \ action skbedit queue_mapping 9 skip_sw Packets destined to 192.168.8.100 will be forwarded to rx queue 4 of eth2 interface.
