2021-08-27vlib: vpp banner is outputted to non-interactive vppctl sessionSteven Luong1-0/+11
Running a batch file which contains many vppctl commands, occasionally, VPP may spit out the banner for some of the commands. This happens when VPP erroneously views the vppctl session as interactive. A simple way to recreate the problem is to run a batch script as followed while [ 1 ] do vppctl create loopback interface vppctl delete loopback interface intfc loop0 done We have two processes which may display the banner, unix_cli_new_session_process and unix_cli_process. Normally, unix_cli_process parses the input tokens and displays the banner after it negotiates the terminal type with the vppctl app. unix_cli_new_session_process only displays the banner just in case the client fails to negotiate terminal type. It runs on a timer and expires in 1 second to display the banner if by then the terminal type is still not yet negotiated. The problem is when the session is killed or exitted, VPP does not remove the element that was enqueued for cli_new_session_process. The index for the connection (cf) is recycled. The timer for the queue element continues to run. When the timer expires for the queue element, it finds the wrong new session due to index recycling. If the new session has not had negotiated the terminal type, the banner is printed erroneously to the new session from cli_new_session_process. The fix is to clean up the queue element to stop cli_new_session_process from processing the wrong connection when the session is killed.

2021-08-19nat: handle ED in2out ICMP errors with workersMatthew Smith1-0/+22
Type: fix With endpoint dependent NAT44, When there are multiple workers we look for a flow which matches the packet in order to figure out which worker should handle the packet. If the packet is an ICMP error, it may be associated with an existing flow by inspecting the L3/L4 headers that are included in the message payload. This was not being done for in2out packets in nat44_ed_get_in2out_worker_index(), so some packets which were related to an open session were not being associated with that session and were being passed to a different thread than the one where the session was created. Later on, when the packet was processed by the fast path in2out node, the L3/L4 headers in the payload are inspected and the fast path node finds the existing session. Since that session is owned by a different thread than the one the packet is being processed by, the in2out fast path node can potentially access the wrong session and/or memory adjacent to the session pool. This can cause a SEGV. Make nat44_ed_get_in2out_worker_index() look at the inner headers when processing an ICMP error. THis is already done in nat44_ed_get_out2in_worker_index() and in the fast path in2out node. Change-Id: Icdc1abebcbce452ee7be7cb23fc563e09bf575f2 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2021-08-17nat: fix counters increment for output featureAlexander Chernavin3-68/+93
Type: fix The NAT plugin stores packet counters and a counter represents a vector indexed by interface index. When an interface is assigned a NAT role, the counters are validated to be long enough for the given interface index. When a packet traverses NAT in2out and output feature is disabled, the appropriate counters are updated by the RX interface index. In this case, translation happens on the inside interface and its index was ensured to be valid in all of the counters during NAT role assignment. When a packet traverses NAT in2out and output feature is enabled, the appropriate counters are updated by the RX interface index too. In this case, translation happens on the outside interface and the packet could be received on any interface, even with no NAT role assigned. If that's the case and its index is greater than the greatest index validated in the counters, a new counter value will be written to memory that does not belong to the counter. As a result, a crash will occur at some point. With this change, use TX interface index to update the counters when output feature is enabled. TX interface is an actual interface where translation happens and its index is always valid in the counters.
