2024-05-08ethernet: check destination mac for L3 in ethernet-input nodeSteven Luong19-54/+58
When the NIC does not support mac filter, we rely on ethernet-input node to do the destination mac check, ie, when the interface is in L3, the mac address for the packet must be the mac address of the interface where the packet arrives. This works fine in ethernet-input node when all packets in the frame might have different interfaces, ie, ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is not set in the frame. However, when all packets are having the same interface, ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is set, ethernet-input node goes through the optimized routine eth_input_single_int -> eth_input_process_frame. That is where dmac check has a bug when all packets in the frame are either, ip4, ip6, or mpls without vlan tags. Because without vlan tags, the code handles all packets in fast path and ignores dmac check. With vlan tags, the code goes to slow path where dmac check is handled properly. The fix is to check if we have a bad dmac in the fast path and force the code to go to slow path which will handle dmac check properly. Also do a wholesale correction on all the testcases which do not use the proper dmac when sending L3 packets.

2024-05-06vlib: revert automatic core pinning changesHadi Rayan Al-Sandid1-328/+0
This reverts commit 71c32a898941e32b5d4f865b50fbe775560c582d. Type: fix Reason for revert: vnet pinning is not considered in this patch. This causes keywords 'workers' and 'skip-cores' to be broken, as well as keyword 'main-core auto' introduced in this patch.

2024-04-09mpls: fix default mpls lb hash configVladislav Grishenko1-6/+101
In case of multiple path within tunnel, mpls lookup node computes lb hash with mpls_compute_flow_hash config value 0, so only mpls label and l4 ports gets accounted, not 5-tuple. This leads to flow traffic polarization and disbalance over mpls paths. Use mpls hash config from lb instead, usually it'll be MPLS_FLOw_HASH_DEFAULT with 5-tuple plus flowlabel. As optimization, fix flow hash reuse from the previous lookup node if present, like ip_lookup does. Previously mpls lookup always calcs the hash. Test lb distribution for both cases. Also, use the same flow hash hex format in ip4/ip6 and mpls traces for easier reading, most code changes is due fixstyle formatting.

Gnu sed is available to be invoked as gsed on FreeBSD systems, but there is no executable or symlink which allows sed to be run by the name gsed on ubuntu 22.04. Check for the existence of gsed.

2024-04-02l2: fix vxlan src port entropy with mpls payloadVladislav Grishenko2-3/+80
l2 tunnels like vxlan, gtpu, geneva use vnet_l2_compute_flow_hash() to compute flow hash for udp src port entropy. In case of inner mpls tunnels to the same lsr ethernet src and dst macs are the same, so l2 flow hash is also the same leading to no src port entropy and the only rss queue overflow on receiver side. Fix it for all the possible vnet_l2_compute_flow_hash callers by making mpls playload hash in additon to ip4/ip6.

2024-03-07flowprobe: fix flush callbacks when multiple workersAlexander Chernavin1-2/+0
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.

2024-02-19ipsec: check each packet for no algs in esp-encryptMatthew Smith1-1/+23
In esp_encrypt_inline(), if two or more consecutive packets are associated with the same SA which has no crypto or integrity algorithms set, only the first one gets dropped. Subsequent packets either get sent (synchronous crypto) or cause a segv (asynchronous crypto). The current SA's index and pool entry are cached before it can be determined whether the packet should be dropped due to no algorithms being set. The check for no algorithms is only performed when the cached SA index is different than the SA index for the current packet. So packets after the first one associated with the "none" alg SA aren't handled properly. This was broken by my previous commit ("ipsec: keep esp encrypt pointer and index synced") which fixed a segv that occurred under a different set of circumstances. Check whether each packet should be dropped instead of only checking when a new SA is encountered. Update unit tests: - Add a test for no algs on tunnel interface which enables asynchronous crypto. - Send more than one packet in the tests for no algs.

2023-11-12flowprobe: 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.
