2023-12-01flowprobe: fix tx flows generated for rewritten trafficAlexander Chernavin1-0/+75
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.

2023-12-01flowprobe: fix clearing interface state on feature disablingAlexander Chernavin1-1/+20
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.

2023-12-01flowprobe: fix accumulation of tcp flags in flow entriesAlexander Chernavin1-0/+74
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.

2023-12-01fib: only update glean for interface if necessaryMatthew Smith1-9/+12
Type: improvement If an interface address is added, the glean adjacency for it's covering prefix is updated with that address. In the case of multiple addresses within the same prefix being added, the most recently added one will end up being used as the sender protocol address for ARP requests. Similar behavior occurs when an interface address is deleted. The glean adjacency is updated to some appropriate entry under it's covering prefix. If there were multiple interface addresses configured, we may update the address on the adjacency even though the address currently in use is not the one being deleted. Add a new value PROVIDES_GLEAN to fib_entry_src_flag_t. The flag identifies whether a source interface entry is being used as the address for the glean adjacency for the covering prefix. Update logic so that the glean is only updated on adding an interface address if there is not already a sibling entry in use which has the flag set. Also, only update the glean on deleting an interface address if the address being deleted has the flag set. Also update unit test which validates expected behavior in the case where multiple addresses within a prefix are configured on an interface.

2023-12-01flowprobe: fix sending L4 fields in L2 template and flowsAlexander Chernavin1-7/+40
Currently, when L2 and L4 recording is enabled on the L2 datapath, the L2 template will contain L4 fields and L2 flows will be exported with those fields always set to zero. With this fix, when L4 recording is enabled, add L4 fields to templates other than the L2 template (i.e. to the IP4, IP6, L2_IP4, and L2_IP6 templates). And export L2 flows without L4 fields. Also, cover that case in the tests.

2023-12-01flowprobe: fix corrupted packets sent after feature disablingAlexander Chernavin1-0/+38
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.

2023-12-01ethernet: run callbacks for subifs too when mac changesAlexander Chernavin1-3/+103
When MAC address changes for an interface, address change callbacks are executed for it. In turn adjacencies register a callback for MAC address changes to be able to update their rewrite strings accordingly. Subinterfaces inherit MAC address from the parent interface. When MAC address of the parent interface changes, it also implies MAC address change for its subinterfaces. The problem is that this is currently not considered when address change callbacks are executed. After MAC address change on the parent interface, packets sent from subinterfaces might have wrong source MAC address as the result of stale adjacencies. For example, ARP messages might be sent with the wrong (previous) MAC address and address resolution will fail. With this fix, when address change callbacks are executed for an interface, they will be also executed for its subinterfaces. And adjacencies will be able to update accordingly.

2023-12-01flowprobe: fix sending L2 flows using L2_IP6 templateAlexander Chernavin1-2/+68
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. And in the end, the current value of "template_id" is saved for L2 template. The problem is that "template_id" at that point contains the ID of L2_IP6 template. With this fix, save the template ID immediately after adding a template for all variants (datapaths). Also, cover the case with a test.

2023-07-13lb: Fix src_ip_sticky evaluation bug in per-port-vip case.Nobuhiro MIKI1-0/+32
Before this fix, the src_ip_sticky flag was passed as an argument to the lb_node_get_hash function, which computes a hash value for a packet. However, in per-port-vip case, the value of src_ip_sticky flag may be different for each port number. As a result, the value is the same for all port numbers, even though it is a per-port-vip case. This commit fixes the src_ip_sticky evaluation by delaying it until the packet is received, so that the correct value is obtained. Also, the unit test case has been enhanced for this bug fix.
