2022-03-24fib: Fix crash when removing a covering prefixNeale Ranns3-10/+18
Type: fix When a covering entry is removed from the table, the covered entries first see it 'updated' and then 'removed'. the crash occurs because the covered prefixes share (simple pointer copy) the covereds hash table of path extensions. During the cervers deletion this hash table has been removed and the update of the covered crashes when recaluationg forwarding becuase it uses the free'd hash. Fix is to refetch the shared hash table (which is NULL) when the covered is updated. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: Icefca9d7b21da975111d0e974d75f663fc0cc00c

2022-03-18session: add infra for safe pool reallocsFlorin Coras2-0/+148
This is not to be used lightly. The idea is to forces pool reallocs to be done only on main thread with a barrier to make sure pools are always reallocated without peekers/readers. If rpcs are delayed and the pool runs out of elements, workers will block waiting for barrier and force the realloc. Consumers of this api should be session layer and transports.

2022-03-15flow: add generic flow pattern for 5G flow enhancementTing Xu2-32/+71
In order to support the requirement of RSS and packet steering of new protocols, such as GTPU PDU-type and QFI, for 5G UPF, a generic pattern is introduced in vnet flow. The generic flow pattern is based on DDP (Dynamic Device Personalization) function and Parser Library module in DPDK. Using generic flow pattern, we do not need to create new packet and field type and offset in API parser for every new protocols. We can create flows for any protocol immediately as long as supported by DDP. The generic flow can be used to support 5G related protocols in different scenarios. The input of this generic pattern are two binary strings for spec and mask. Spec is the binary presentation of the target packet type, and mask is used to mark the target fields. In this patch DPDK plugins is enabled for POC. Next step we will enable generic flow in native IAVF, which is the main target. Here is an example. If we want to create a flow for GTPU QFI, spec is: 00000000000100000000000208004500003C00000000001100000101010102020202000 008680028000034FF001C00000000000000850100010045000014000000000000000001 01010102020202 mask is: 00000000000000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000007F0000000000000000000000000000 00000000000000 A naming API POC is created via VAPI to help create the rule with the target packet format similar to Scapy. It is based on a function module called PacketForge. In this way, the user no need to create binary string spec and mask by themselves.

2022-03-08ipsec: input: drop by default for non-matching pktsZachary Leaf1-0/+14
As per IPSec RFC4301 [1], any non-matching packets should be dropped by default. This is handled correctly in ipsec_output.c, however in ipsec_input.c non-matching packets are allowed to pass as per a matched BYPASS rule. For full details, see: https://lists.fd.io/g/vpp-dev/topic/ipsec_input_output_default/84943480 It appears the ipsec6_input_node only matches PROTECT policies. Until this is extended to handle BYPASS + DISCARD, we may wish to not drop by default here, since all IPv6 traffic not matching a PROTECT policy will be dropped.

2022-03-08ip: set fib_index before exiting input ACL nodeArthur de Kerhor1-40/+75
While setting an ACL, a user can specify the adjacency to follow after the input ACL node. Thus, we may skip a lookup and enter directly a local node (ex: ip4_local). To prevent the local source check from failing, we need to specify the fib index. And, we have to do it just before exiting the input ACL node because the l2_classify object is overlapping with the fib_index in the vnet_buffer_opaque_t struct. We could have added a padding to avoid this overlap but there is no place for that in the structure.
