2023-08-23octeontx2-pf: Use PTP HW timestamp counter atomic update featureSai Krishna
Some of the newer silicon versions in CN10K series supports a feature where in the current PTP timestamp in HW can be updated atomically without losing any cpu cycles unlike read/modify/write register. This patch uses this feature so that PTP accuracy can be improved while adjusting the master offset in HW. There is no need for SW timecounter when using this feature. So removed references to SW timecounter wherever appropriate.

2023-08-11octeontx2-pf: Allow both ntuple and TC features on the interfaceHariprasad Kelam
The current implementation does not allow the user to enable both hw-tc-offload and ntuple features on the interface. These checks are added as TC flower offload and ntuple features internally configures the same hardware resource MCAM. But TC HTB offload configures the transmit scheduler which can be safely enabled on the interface with ntuple feature. This patch adds the same and ensures only TC flower offload and ntuple features are mutually exclusive.

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.

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

2023-06-13octeontx2-af: Set XOFF on other child transmit schedulers during SMQ flushNaveen Mamindlapalli
When multiple transmit scheduler queues feed a TL1 transmit link, the SMQ flush initiated on a low priority queue might get stuck when a high priority queue fully subscribes the transmit link. This inturn effects interface teardown. To avoid this, temporarily XOFF all TL1's other immediate child transmit scheduler queues and also clear any rate limit configuration on all the scheduler queues in SMQ(flush) hierarchy.

The DWRR MTU config added for SDP and RPM/LBK links on CN10K silicon is further extended on CK10KB silicon variant and made it configurable. Now there are 4 DWRR MTU config to choose while setting transmit scheduler's RR_WEIGHT. Here we are reserving one config for each of RPM, SDP and LBK. NIXX_AF_DWRR_MTUX(0) ---> RPM NIXX_AF_DWRR_MTUX(1) ---> SDP NIXX_AF_DWRR_MTUX(2) ---> LBK PF/VF drivers can choose the DWRR_MTU to be used by setting SMQX_CFG[pkt_link_type] to one of above. TLx_SCHEDULE[RR_WEIGHT] is to be as configured 'quantum / 2^DWRR_MTUX[MTU]'. DWRR_MTU of each link is exposed to PF/VF drivers via mailbox for RR_WEIGHT calculation.

2023-06-13octeontx2-af: extend RSS supported offload typesKiran Kumar K
Add support to select L3 SRC or DST only, L4 SRC or DST only for RSS calculation. AF consumer may have requirement as we can select only SRC or DST data for RSS calculation in L3, L4 layers. With this requirement there will be following combinations, IPV[4,6]_SRC_ONLY, IPV[4,6]_DST_ONLY, [TCP,UDP,SCTP]_SRC_ONLY, [TCP,UDP,SCTP]_DST_ONLY. So, instead of creating a bit for each combination, we are using upper 4 bits (31:28) in the flow_key_cfg to represent the SRC, DST selection. 31 => L3_SRC, 30 => L3_DST, 29 => L4_SRC, 28 => L4_DST. These won't be part of flow_cfg, so that we don't need to change the existing ABI.

2023-06-13octeontx2-af: Add devlink option to adjust mcam high prio zone entriesNaveen Mamindlapalli
The NPC MCAM entries are currently divided into three priority zones in AF driver: high, mid, and low. The high priority zone and low priority zone take up 1/8th (each) of the available MCAM entries, and remaining going to the mid priority zone. The current allocation scheme may not meet certain requirements, such as when a requester needs more high priority zone entries than are reserved. This patch adds a devlink configurable option to increase the number of high priority zone entries that can be allocated by requester. The max number of entries that can be reserved for high priority usage is 100% of available MCAM entries. Usage: 1) Change high priority zone percentage to 75%: devlink -p dev param set pci/0002:01:00.0 name npc_mcam_high_zone_percent \ value 75 cmode runtime 2) Read high priority zone percentage: devlink -p dev param show pci/0002:01:00.0 name npc_mcam_high_zone_percent The devlink set configuration is only permitted when no MCAM entries are assigned, i.e., all MCAM entries are free, indicating that no PF/VF driver is loaded. So user must unload/unbind PF/VF driver/devices before modifying the high priority zone percentage.
