2022-06-28ipsec: change wildcard value for any protocol of spd policyPiotr Bronowski5-21/+21
Currently 0 has been used as the wildcard representing ANY type of protocol. However 0 is valid value of ip protocol (HOPOPT) and therefore it should not be used as a wildcard. Instead 255 is used which is guaranteed by IANA to be reserved and not used as a protocol id.

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. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.

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

This then allows more precise packet counter verification by first defining a "zero" dictionary, e.g. for ED NAT: cls.no_diff = StatsDiff({ pg.sw_if_index: { '/nat44-ed/in2out/fastpath/tcp': 0, '/nat44-ed/in2out/fastpath/udp': 0, '/nat44-ed/in2out/fastpath/icmp': 0, '/nat44-ed/in2out/fastpath/drops': 0, '/nat44-ed/in2out/slowpath/tcp': 0, '/nat44-ed/in2out/slowpath/udp': 0, '/nat44-ed/in2out/slowpath/icmp': 0, '/nat44-ed/in2out/slowpath/drops': 0, '/nat44-ed/in2out/fastpath/tcp': 0, '/nat44-ed/in2out/fastpath/udp': 0, '/nat44-ed/in2out/fastpath/icmp': 0, '/nat44-ed/in2out/fastpath/drops': 0, '/nat44-ed/in2out/slowpath/tcp': 0, '/nat44-ed/in2out/slowpath/udp': 0, '/nat44-ed/in2out/slowpath/icmp': 0, '/nat44-ed/in2out/slowpath/drops': 0, } for pg in cls.pg_interfaces }) and then to specify only changed counters directly when calling one of send_and_* functions: self.send_and_assert_no_replies( self.pg0, pkts, msg="i2o pkts", stats_diff=self.no_diff | { "err": { '/err/nat44-ed-in2out-slowpath/out of ports': len(pkts), }, self.pg0.sw_if_index: { '/nat44-ed/in2out/slowpath/drops': len(pkts), }, } ) operator | is overloaded by StatsDiff class to perform a deep merge operation, so in above case, dictionaries for "err" and self.pg0.sw_if_index do not overwrite whole sub-dictionaries, rather the contents are merged, assuring that all the remaining counters are verified to be zero.

2022-02-18tests: Consolidate the implementations of send_and_expect_XNeale Ranns4-53/+18
Type: test there were multiple instances of send_and_expect_load_balancing and a send_and_expect_one_itf which has the same functionality as send_and_expect_one. Put one implementation of both in framework.py (where the other send_and_X functions reside). Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I7f629d440220bee29368067f475059322e1134f7

2022-02-17ipsec: Improve the handling of NAT-T keepalive messagesNeale Ranns1-1/+13
Type: improvement Ethernet frames on the wire are a minimum of 64 bytes, so use the length in the UDP header to determine if the ESP payload is one bytes of the special SPI, rather than the buffer's size (which will include the ethernet header's padding). In the case of drop advance the packet back to the IP header so the ipx-drop node sees a sane packet.
