Just like commit 252647482b24bb3474e8f13bc86100718176832f did for Wireguard interface keys, prevent stack smashing the peer keys. Integer math on 32 bytes of base64 data might yield 33 bytes of data in some poorly formed user input of private key values. Rather than smashing the stack (detected) and aborting, simply allow for the possible yet irrelevant 33-rd byte of data.

When dNAT-ing to a VIP, it can happen that the return session conflicts with another forward session than the one we own.

2022-03-15flow: add generic flow pattern for 5G flow enhancementTing Xu1-0/+16
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.

2022-03-07linux-cp: handle ipv4 routes when interface is disabledAlexander Chernavin1-2/+88
Type: improvement Currently, when an interface is brought down administratively, IPv4 routes that resolve through that interface remain in the FIB. However, the kernel removes those routes but doesn't send any notifications about that. Desynchronization between the kernel and VPP happens. With this change, when a notification received from the kernel indicating that an interface was brought down, in addition to bringing the VPP interface down, walk the IPv4 FIB bound to that interface and remove any entries that resolve through that interface and were added with one of the linux-cp FIB sources.

2022-03-04linux-cp: stop ignoring ENOBUFS while reading notifAlexander Chernavin1-9/+2
Type: improvement Currently, while reading notifications, ENOBUFS error is ignored and reading continues. This was done to minimize the number of notifications that are lost due to reopening the socket. Now that synchronization is implemented to recover from socket errors, ignoring ENOBUFS and reading as much notifications as possible is not actual. Before synchronization, all currently enqueued notification are discarded in any case. With this change, stop reading notifications if any error occurs.

If some entries are no longer present in the set being loaded but present in VPP, they should be removed to fully syncronize. With this change, add handlers for sync begin and end events. Begin handlers will mark the entries as stale. End handlers will remove the entries that are still marked as stale.

2022-03-03linux-cp: reflect hw link state on tap on pair creationAlexander Chernavin1-0/+14
Type: fix Currently, a tap interface created to be a member of a linux-cp pair has default link state (down) and default link speed (10Mb/s). Then the plugin monitors the link state of the paired hardware interface and if it changes, the new link state is reflected on the tap interface. And when the new link state is "up", the link speed is also reflected on the tap interface. The problem is that this scheme implies that the hardware interface's link state is "down" at the moment of the linux-cp pair creation and then changes. But there are cases when the link state is already "up" at that moment. If that is the case, the link speed on the tap interface will remain the default one until the link comes down and then comes up. With this fix, when a linux-cp pair is created, reflect current link state of the hardware interface being paired on the created tap interface.

The data being passed to the main thread included a pointer to the VRRP header in the received packet buffer. Since the main thread processes the RPC request asynchronously from the worker thread, it's possible for the worker to drop the packet and for the buffer to be overwritten before the main thread can process it. Copy the fields which may be needed by the main thread into a struct instead of passing a pointer to a packet buffer.
