2023-12-15rdma: add rdma_create_v4 that handles flags properlyVratko Polak4-2/+136
The _v3 was not handling endianness on flags (e.g. mode). Marking _v3 as deprecated, but keeping it as there might be users who learned to preprocess their flag values. + Also, format PCI product_name as a vector, not a string.

2023-11-14flowprobe: fix L3 header offset calculation for tx flowsAlexander Chernavin1-1/+1
The recent TX flows generation fix introduced "l3_hdr_offset" which represents the offset of the IP header in the buffer's data. The problem is that it is erroneously defined as a 16-bit unsigned integer. If the calculated offset is negative, "l3_hdr_offset" will get a value close to UINT16_MAX. And the code will search the IP header somewhere beyond the buffer's data. For example, this will occur in the case when an ICMP error is being sent in response to a received packet. With this fix, make "l3_hdr_offset" a signed integer. Type: fix Change-Id: I6f1283c7ba02656d0f592519b5863e68348c5583 Signed-off-by: Alexander Chernavin <achernavin@netgate.com>

2023-11-12flowprobe: fix tx flows generated for rewritten trafficAlexander Chernavin1-5/+7
Currently, when IPFIX records generation is enabled for an interface in the TX direction, some rewritten traffic is being sent from that interface, and the Ethernet header's location has changed due to rewriting, generated TX flows will contain fields with wrong and zero values. For example, that can be observed when traffic is rewritten from a subinterface to a hardware interface (i.e. when tags are removed). A TX flow generated in this case will have wrong L2 fields because of an incorrectly located Ethernet header. And zero L3/L4 fields because the Ethernet type will match neither IP4 nor IP6. The same code is executed to generate flows for both input and output features. And the same mechanism is applied to identify the Ethernet header in the buffer's data. However, such general code usually works with the buffer's data conditionally based on the direction. For most input features, the buffer's current_data will likely point to the IP header. For most output features, the buffer's current_data will likely point to the Ethernet header. With this fix: - Keep relying on ethernet_buffer_get_header() to locate the Ethernet header for input features. And start using vlib_buffer_get_current() to locate the Ethernet header for output features. The function will account for the Ethernet header's position change in the buffer's data if there is rewriting. - After fixing Ethernet header determination in the buffer's data, L3/L4 fields will contain non-zero but still incorrect data. That is because IP header determination needs to be fixed too. It currently relies on the fact that the Ethernet header is always located at the beginning of the buffer's data and that l2_hdr_sz can be used as an IP header offset. However, this may not be the case after rewriting. So start calculating the actual offset of the IP header in the buffer's data. - Add a unit test to cover the case.

2023-11-10gtpu: support non-G-PDU packets and PDU SessionRune E. Jensen8-527/+2551
Updated the gtpu plugin code to support the PDU Session user plane protocol, required for 5G, as specified in 3GPP TS 38.415 version 17.0.0. This enables some initial support of 5G gNodeB's with the gtpu plugin. New features: - Basic support for the GTP-U Extension Header Flag. Packets with one extension can now be decapsulated. This enables basic support of the PDU Session user plane protocol (3GPP TS 38.415 version 17.0.0). New tunnels can be created with a PDU enable flag and a 6-bit QoS Flow Identifier (QFI). With this, encapsulated packets will have the PDU Session extension header, and the QFI set. - Ability to forward GTP-U packets that are not handled by the plugin directly. Only GTP-U packets with a message type of 255 (G-PDU) are handled directly. However, 3GPP TS 29.281 defines several other message types like echo and error indication. A new feature is added to optionally forward unknown or unsupported packets to a new IP address. This works separately for unknown GTP-U message types, unknown TEIDs, and packets with an unknown GTP-U header. This allows both echo and error indications from a 5G gNodeB to be handled by a different system outside VPP. - Simple way to get metrics for active tunnels and on tunnel close. In 5G session/tunnel lifetime is often short and created frequently. The normal API becomes too slow and inaccurate when too many tunnels are created and deleted every second. Improvements: - A clean ground structure to handle multiple message type in the future. The code path for G-PDU packets is optimized for performance, representing the typical case. Unsupported GTP-U packets enter a slow path that decodes the nature of the error. This presents a easy hook to handle other message types in the future. - Improved error reporting When using traces there is more details in the tunnel descriptions. - Updated the API with several enums. Fixes: - gtpu0->length field in IPv6 was computed with IPv4 header lengths in the encapsulation code. - vec_set_len (t->rewrite, ...) size was computed with the IPv4 header size also for IPv6 tunnels. Issues: - This PR does not enable full support of the 3GPP specification. In particular it only supports a single QoS/QFI flow for each tunnel. It ignores all incoming extension header flags. - API functions might change again when/if more support of the 3GPP TS 38.415 spec is added. Note that I have bumped the API version to 2.1.0 as it seems to be the correct approach based on my API changes. Type: feature Signed-off-by: Rune E.

2023-11-07af_packet: remove UNIX_FILE_EVENT_EDGE_TRIGGERED flagArtem Glazychev1-1/+0
af_packet does not process data until the interface is UP. If after interface creation, but before it is UP, the host interfaces are flooded, then blocking case may occur - VPP interface will never be able to process the data. If the EDGE_TRIGGERED flag is set, the event will not arrive, because nothing new is happening anymore (probably because the queue is already full). Therefore, we need to use LEVEL_TRIGGERED (default value), which indicates that there is still unprocessed data (accumulated after interface creation, but before it was UP).

2023-11-07flowprobe: fix clearing interface state on feature disablingAlexander Chernavin1-0/+3
As a result of recent fixes, all currently stored flows of an interface are deleted when the feature is being disabled for the interface. This includes stopping the timer and freeing the flow entries for further reuse. The problem is that meta information is not cleared in the flow entries being deleted. For example, packet delta count will keep its value. The next flow that gets one of these pool entries will already have a non-zero packet count. So the counting of packets will start from a non-zero value. And incorrect packet delta count will be exported for that flow. With this fix, clear meta information too when clearing interface state. Also, update the corresponding test to cover this case. Type: fix Change-Id: I9a73b3958adfd1676e66b0ed50f1478920671cca Signed-off-by: Alexander Chernavin <achernavin@netgate.com>
2023-11-06dpdk: correct the printing of Rx offloading flagsJieqiang Wang1-1/+1
DPDK added new Rx checksum flags[1] to handle cases like the virtual drivers. Current check of flags is not strict enough for flags like RTE_MBUF_F_RX_IP_CKSUM_NONE and will always be true no matter the checksum in packet is good or bad. Fix this issue by comparing the result of AND operation with the correspinding Rx checksum flags. Before this patch, packet trace prints the offload flags as below: Packet Offload Flags PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid PKT_RX_IP_CKSUM_NONE (0x0090) no IP cksum of RX pkt. PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid PKT_RX_L4_CKSUM_NONE (0x0108) no L4 cksum of RX pkt. After this patch, packet offload flags would be like: Packet Offload Flags PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid Type: fix [1] https://github.com/DPDK/dpdk/commit/5842289a546ceb0072bd7faccb93821e21848e07 Signed-off-by: Jieqiang Wang <jieqiang.wang@arm.com> Change-Id: I3182022d9ccd46b2fc55bb3edfbfac9062ed7c89

2023-10-30flowprobe: fix accumulation of tcp flags in flow entriesAlexander Chernavin1-0/+1
Currently, TCP flags of a flow entry don't get reset once the flow is exported (unlike other meta information about a flow - packet delta count and octet delta count). So TCP flags are accumulated as long as the flow is active. When the flow expires, it is exported the last time, and its pool entry is freed for further reuse. The next flow that gets this pool entry will already have non-zero TCP flags. If it's a TCP flow, the flags will keep being accumulated. This might look fine when exported. If it's a non-TCP flow, that will definitely look erroneous. With this fix, reset TCP flags once the flow is exported. Also, cover the reuse case with tests.

2023-10-16flowprobe: fix corrupted packets sent after feature disablingAlexander Chernavin3-2/+54
When IPFIX flow record generation is enabled on an interface and the active timer is set, flows will be saved and then exported according to the active and passive timers. If then disable the feature on the interface, the flow entries currently saved will remain in the state tables. They will gradually expire and be exported. The problem is that the template for them has already been removed. And they will be sent with zero template ID which will make them unreadable. A similar problem will occur if feature settings are "changed" on the interface - i.e. disable the feature and re-enable it with different settings (e.g. set a different datapath). The remaining flows that correspond to the previous feature settings will be eventually sent either with zero template ID or with template ID that corresponds to the current feature settings on the interface (and look like garbage data). With this fix, flush the current buffers before template removal and clear the remaining flows of the interface during feature disabling.

Currently, L2 flows are exported using L2_IP6 template if L3 or L4 recording is enabled on L2 datapath. That occurs because during feature enable, L2 template is added and its ID is not saved immediately. Then L2_IP4 and L2_IP6 templates are added overwriting "template_id" each time.
