2022-09-15nat: fix nat44-ed port range with multiple workersVladislav Grishenko1-1/+192
The number of available dynamic ports is set to (0xffff - 1024) = 64511, which is not divisable by the pow2 number of workers - the only integer divisors are 31 and 2081. So, total dynamic port range of all workers will be less than it: 1 wrk: n = (port_per_thread = 64511/1)*1 = 64511 + 1025 = 65536 2 wrk: n = (port_per_thread = 64511/2)*2 = 64510 + 1025 = 65535 4 wrk: n = (port_per_thread = 64511/4)*4 = 64508 + 1025 = 65533 8 wrk: n = (port_per_thread = 64511/8)*8 = 64504 + 1025 = 65529 ... As seen, with multiple workers there are unused trailing ports for every nat pool address and that is the reason of out-of-bound index in the worker array on out2in path due (port - 1024) / port_per_thread math. This was fixed in 5c9f9968de63fa627b4a72b344df36cdc686d18a, so packets to unused ports will go to existing worker and dropped there. Per RFC 6335 https://www.rfc-editor.org/rfc/rfc6335#section-6: 6. Port Number Ranges o the System Ports, also known as the Well Known Ports, from 0-1023 (assigned by IANA) o the User Ports, also known as the Registered Ports, from 1024- 49151 (assigned by IANA) o the Dynamic Ports, also known as the Private or Ephemeral Ports, from 49152-65535 (never assigned) According that let's allocate dynamic ports from 1024 and have full port range with a wide range of the workers number - 64 integer divisors in total, including pow2 ones: 1 wrk: n = (port_per_thread = 64512/1)*1 = 64512 + 1024 = 65536 2 wrk: n = (port_per_thread = 64512/2)*2 = 64512 + 1024 = 65536 3 wrk: n = (port_per_thread = 64512/3)*3 = 64512 + 1024 = 65536 4 wrk: n = (port_per_thread = 64512/4)*4 = 64512 + 1024 = 65536 5 wrk: n = (port_per_thread = 64512/5)*5 = 64510 + 1024 = 65534 6 wrk: n = (port_per_thread = 64512/6)*6 = 64512 + 1024 = 65536 7 wrk: n = (port_per_thread = 64512/7)*7 = 64512 + 1024 = 65536 8 wrk: n = (port_per_thread = 64512/8)*8 = 64512 + 1024 = 65536 ... Modulo from 5c9f9968de63fa627b4a72b344df36cdc686d18a is still required when the numbers of workers is not the integer divisor of 64512.

Type: improvement If an SA protecting an IPv6 tunnel interface has UDP encapsulation enabled, the code in esp_encrypt_inline() inserts a UDP header but does not set the next protocol or the UDP payload length, so the peer that receives the packet drops it.

2022-08-17wireguard: fix fib entry trackingAlexander Chernavin1-0/+83
Type: fix After peers roaming support addition, FIB entry tracking stopped working. For example, it can be observed when an adjacency is stacked on a FIB entry by the plugin and the FIB entry hasn't got ARP resolution yet. Once the FIB entry gets ARP resolution, the adjacency is not re-stacked as it used to. This results in endless ARP requests when a traffic is sent via the adjacency. This is broken because the plugin stopped using "midchain delegate" with peers roaming support addition. The reason is that "midchain delegate" didn't support stacking on a different FIB entry which is needed when peer's endpoint changes. Now it is supported there (added in 36892). With this fix, start using "midchane delegate" again and thus, fix FIB entry tracking. Also, cover this in tests.

2022-06-10vcl: fix iperf3 server crash issue when it runs over vpp host stack.Liangxing Wang1-0/+11
Issue: Let iperf3 server run via ldp and vcl on top of vpp's host stack. If iperf3 client connects this iperf3 server with tcp MSS setting option, iperf3 server will always crash. Root cause: When MSS option is specified by iperf3 client, iperf3 server will recreate the listening socket firstly, then call setsockopt() to set MSS immediately. Iperf3 code can be referred here: https://github.com/esnet/iperf/blob/58332f8154e2140e40a6e0ea060a418138291718/src/iperf_tcp.c#L186. However, in vcl layer vpp_evt_q of this recreated session is not allocated yet. So iperf3 server crashes with vpp_evt_q null pointer access. Fix: Add session vpp_evt_q null pointer check in vcl_session_transport_attr(). Add a vcl test case for this MSS option scenario.

2022-06-05wireguard: fix crash by not sending arp via wg interfaceAlexander Chernavin1-8/+54
Type: fix Currently, neighbor adjacencies on a wg interface are converted into a midchain only if one of the peers has a matching allowed prefix configured. If create a route that goes through a wg interface but the next-hop address does not match any allowed prefixes, an ARP/ND request will try to be sent via the wg interface to resolve the next-hop address when matching traffic occurs. And sending an ARP request will cause VPP to crash while copying hardware address of the wg interface which is NULL. Sending an ND message will not cause VPP to crash but the error logged will be unclear (no source address). With this fix, convert all neighbor adjacencies on a wg interface into a midchain and update tests to cover the case. If there is no matching allowed prefix configured, traffic going such routes will be dropped because of "Peer error". No changes if there is matching allowed prefix configured. Also, fix getting peer by adjacency index. Signed-off-by: Alexander Chernavin <achernavin@netgate.com> Change-Id: I15bc1e1f83de719e97edf3f7210a5359a35bddbd

Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting.

2022-04-21nat: tweak rfc7857 tcp connection trackingOle Troan1-24/+20
The RFC7857 state machine introduced in 56c492a is a trade-off. It tries to retain sessions as much as possible and also offers some protection against spurious RST by re-establishing sessions if data is received after the RST. From experience in the wild, this algorithm is a little too liberal, as it leaves too many spurious established sessions in the session table. E.g. a oberserved pattern is: client server <- FIN, ACK ACK -> ACK -> RST, ACK -> With the current state machine this would leave the session in established state. These proposed changes do: - require 3-way handshake to establish session. (current requires only to see SYNs from both sides) - RST will move session to transitory without recovery if data is sent after - Only a single FIN is needed to move to transitory Fixes: 56c492aa0502751de2dd9d890096a82c5f04776d Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I92e593e00b2efe48d04997642d85bd59e0eaa2ea Signed-off-by: Ole Troan <ot@cisco.com>
2022-04-14ipsec: perf improvement of ipsec4_input_node using flow cacheZachary Leaf3-6/+700
Adding flow cache support to improve inbound IPv4/IPSec Security Policy Database (SPD) lookup performance. By enabling the flow cache in startup conf, this replaces a linear O(N) SPD search, with an O(1) hash table search. This patch is the ipsec4_input_node counterpart to https://gerrit.fd.io/r/c/vpp/+/31694, and shares much of the same code, theory and mechanism of action. Details about the flow cache: Mechanism: 1. First packet of a flow will undergo linear search in SPD table. Once a policy match is found, a new entry will be added into the flow cache. From 2nd packet onwards, the policy lookup will happen in flow cache. 2. The flow cache is implemented using a hash table without collision handling. This will avoid the logic to age out or recycle the old flows in flow cache. Whenever a collision occurs, the old entry will be overwritten by the new entry. Worst case is when all the 256 packets in a batch result in collision, falling back to linear search. Average and best case will be O(1). 3. The size of flow cache is fixed and decided based on the number of flows to be supported. The default is set to 1 million flows, but is configurable by a startup.conf option. 4. Whenever a SPD rule is added/deleted by the control plane, all current flow cache entries will be invalidated. As the SPD API is not mp-safe, the data plane will wait for the control plane operation to complete. Cache invalidation is via an epoch counter that is incremented on policy add/del and stored with each entry in the flow cache. If the epoch counter in the flow cache does not match the current count, the entry is considered stale, and we fall back to linear search. The following configurable options are available through startup conf under the ipsec{} entry: 1. ipv4-inbound-spd-flow-cache on/off - enable SPD flow cache (default off) 2. ipv4-inbound-spd-hash-buckets %d - set number of hash buckets (default 4,194,304: ~1 million flows with 25% load factor) Performance with 1 core, 1 ESP Tunnel, null-decrypt then bypass, 94B (null encrypted packet) for different SPD policy matching indices: SPD Policy index : 2 10 100 1000 Throughput : Mbps/Mbps Mbps/Mbps Mbps/Mbps Mbps/Mbps (Baseline/Optimized) ARM TX2 : 300/290 230/290 70/290 8.5/290 Type: improvement Signed-off-by: Zachary Leaf <zachary.leaf@arm.com> Signed-off-by: mgovind <govindarajan.Mohandoss@arm.com> Tested-by: Jieqiang Wang <jieqiang.wang@arm.com> Change-Id: I8be2ad4715accbb335c38cd933904119db75827b
2022-04-12ip: fix arc start in ip46-local for local mfib entriesAlexander Chernavin1-2/+22
Type: fix After changes made in f840880, VRRP IPv6 cannot reply for neighbor solicitations requesting the link layer address of the configured virtual address. VRRP IPv6 enables the vrrp6-nd-input feature in the ip6-local feature arc for an interface on which a virtual router is configured. When neighbor solicitations arrive on that interface, ip6-local should start feature arc walk for that interface and the messages should be processed by vrrp6-nd-input. The problem is that currently, the feature arc is started for the interface obtained from the receive DPO that has interface unset (i.e. max u32) for local mfib entries. Thus, the feature arc is started not on the interface the messages were received on and vrrp6-nd-input is not traversed. With this fix, if interface obtained from the receive DPO is unset, use RX interface from the buffer to start the ip46-local feature arc. Also, enable tests of this case for both IPv4 and IPv6 address families that are currently tagged as extended and not run on every change. They configure VRRP with priority 255 and are expected to be stable. Signed-off-by: Alexander Chernavin <achernavin@netgate.com> Change-Id: I11ef3d5a7a986e04431e8613d1510b8666094bd7
2022-04-01vrrp: add stats support and update APIEmanuele Di Pascale1-0/+120
Add simple counter statistics to VRRP, based on a subset of those defined in RFC8347. Add an update API that allows in-place modification of an existing instance. The method returns a vrrp_index which can be used both for retrieving statistics and to modify non-key parameters. Also add a delete method which will take that vrrp_index as parameter.

2022-04-01nat: nat44-ed cleanup & fixesFilip Varga3-23/+19
Set deprecated option on unsupported API calls. Cleaned up API calls with deprecated option. Removed in progress option from long term used API calls. Removed obsolete/unused nodes, functions, variables. Fixed set frame queue nelts function. Calling API would incorrectly not fail even though frame queue nelts can only be set before first call nat44_plugin_enable. Moved all formatting functions to _format.c file.

2022-03-30udp: fix inner packet checksum calculation in udp-encapMauro Sardara1-4/+9
When computing the inner packet checksum, the code wrongly assumes that the IP version of the inner packet is the same of the outer one. On the contrary, it is perfectly possible to encapsulate v6 packets into v4 and viceversa, so we need to check the IP format of the inner header before calling vnet_calc_checksums_inline.
