2024-09-05flowprobe: run input nodes before inacl nodesScott Hutton1-2/+2
Type: fix The flowprobe-input-ip4 node must be run ahead of ip4-inacl in some scenarios to ensure that it sees flows on receiving interfaces. The same is presumably the case for flowprobe-input-ip6, but this hasn't been tested/observed.

2024-03-07flowprobe: fix flush callbacks when multiple workersAlexander Chernavin1-0/+86
IPFIX buffers are stored on a per worker thread basis. Currently, the flush callbacks will flush only buffers stored for the main thread. And buffers for worker threads will not be sent until their size reach the path MTU configured for the exporter. So if traffic is constant, the problem will unlikely to be visible. Buffers will be sent once they reach the maximum size. However, if traffic stops at some point and flush is triggered in order to make the plugin send all currently buffered data, this will not happen. And collectors will not receive that data. The plugin will keep the remaining data until traffic starts again, the buffers reach the maximum size, and be sent. With this fix, flush buffers for worker threads and for the main thread when the flush callbacks are triggered. This will allow to remove @tag_fixme_vpp_workers from the unit tests that don't set timers. The tests that set timers will still be failing for other multi-worker related problems.

2024-01-02flowprobe: fix calling vlib_time_now() from worker threadsAlexander Chernavin1-3/+2
Currently, when flowprobe_export_send() calls vlib_time_now(), a pointer to the main thread's vlib_main_t is always passed (the one cached in flow_report_main). However, that code can also be executed from a worker thread. And passing a pointer to the main thread's vlib_main_t to vlib_time_now() from a worker thread may cause time synchronization issues. Also, running a debug binary will cause an assertion failure in vlib_time_now() in this case. With this fix, flowprobe_export_send() passes the pointer to the current thread's vlib_main_t to vlib_time_how(). This doesn't allow to remove @tag_fixme_vpp_workers from the unit tests yet as they will be failing for other multi-worker related problems.

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.

2023-11-07flowprobe: 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>
2023-10-30flowprobe: 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.

2023-10-18flowprobe: fix sending L4 fields in L2 template and flowsAlexander Chernavin2-3/+13
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. Type: fix Change-Id: Id5ed8b99af5634fb9d5c6e695203344782fdac01 Signed-off-by: Alexander Chernavin <achernavin@netgate.com>
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.

2023-10-12flowprobe: fix sending L2 flows using L2_IP6 templateAlexander Chernavin1-11/+13
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.

2021-11-22ipfix-export: refactor fields in flow_report_mainPaul Atkins2-17/+19
Pull out the fields in flow_report_main_t that are specific to a single exporter and move them into a new structure that represents an exporter. Add a pool of exporters to flow_report_main_t and do a pool_get() to get the entry at index 0, so that the existing users of the code need only change the path at which they access the old fields and have no need to make further code changes. In functions that were accessing the fields that now make up the ipfix_exporter create a local var that points to the first (always valid) exporter and use this as the base for the fields rather than finding them from flow_report_main. This is in preparation for supporting multiple flow_exporters. Note that at the moment the code supports multiple 'streams' for a given exporter, where each stream has its own source port, domain id and template space. But all streams within an exporter have the same destination address, so this is not the same as multiple exporters.

Also add support for a per-message CLI option, that is currently limited to VAT help text. option vat_help = "<help text>"; Type: refactor Change-Id: I245e3104bb76f7e1fb69a59ab20cc7c8dfcdd460 Signed-off-by: Ole Troan <ot@cisco.com>
2019-08-22tests: move plugin tests to src/plugins/*/testDave Wallace1-0/+1082
- Relocate plugin tests for 'make test' into src/plugins/*/test so that plugin test cases are co-located with the plugin source code.

2019-07-09vat: unload unused vat pluginsDave Barach1-21/+2
If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.
