2018-03-07tls: enforce certificate verificationFlorin Coras10-124/+212
- add option to use test certificate in the ca chain - add hostname to extended session endpoint fields and connect api parameters. If hostname is present, certificate validation is enforced. - use /etc/ssl/certs/ca-certificates.crt to bootstrap CA cert. A different path can be provided via startup config Change-Id: I046f9c6ff3ae6a9c2d71220cb62eca8f7b10e5fb Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-03-05SCTP: API to configure some tunablesMarco Varlese6-78/+129
This patch adds the possibility to configure some behaviors of the SCTP stack based on some tunable parameters (mainly ON/OFF). For the time being, that is limited to the bundling option (multiplexing messages) and to delaying the SACK message.

2018-03-05IP6 link-local tableNeale Ranns22-220/+1068
- IPv6 link local table is a per-SW interface array of IPv6 unicast FIBs - the per-interface ocst is sizeof(fib_table_t) which is small, w.r.t. the cost of an interface - FE80::/10 in the 'global' table points to a DPO that performs a lookup in the input interface's LL fib.

2018-03-05SCTP: retransmission in INIT/SHUTDOWN phaseMarco Varlese4-24/+124
This patch addresses the need to handle timers timeouts (e.g. sent chunks not being acked) for both the INIT and SHUTDOWN phases. The INIT phase requires the handling of two timers the T1-init and T1-cookie timers whilst the SHUTDOWN phase requires the handling of the T2-shutdown timer only for the retransmission case. Left to be implemented is the handling of the DATA chunks retransmission (e.g. T3-rxtx expiration) but that will be submitted with a separate patch.

2018-03-03netlink: Use nl_pid 0 to play nice with others.Jon Loeliger1-1/+1
While the netlink field is named nl_pid, and typically contains a process id, setting it to a pid value directly prevents other modules from also using a netlink socket. On the other hand, setting it to 0 allows multiple modules to use a netlink socket by letting the kernel assign the nl_pid a value. This allows the verito tap code to interact nicely with the router plugin's librtnl after, say, tap-inject has been enabled.

For instance, a tls app can offer transport services to other applications. And second, a tls transport app that leverages the mbedtls library for tls protocol implementation.

2018-03-02tapv2: CLI and binary API fixesSteven2-3/+3
1. When interface create encouners an error (see test below), the same id cannot be used again. This is due to hash_set is called too early in the function. After the hash entry is set, there are different errors may cause the interface create to be aborted. But we didn't remove the hash entry when error is encountered. The fix is to move the hash_set call near the end which has no more "goto error" DBGvpp# create tap id 1 rx-ring-size 1021 tx-ring-size 1021 create tap id 1 rx-ring-size 1021 tx-ring-size 1021 create tap: ring size must be power of 2 DBGvpp# create tap id 1 rx-ring-size 1024 tx-ring-size 1024 create tap id 1 rx-ring-size 1024 tx-ring-size 1024 create tap: interface already exists DBGvpp# 2. multiple issues exist with api_format.c with the below command binary-api tap_create_v2 id 4 hw-addr 90:e2:ba:76:cf:2f rx-ring-size 1024 tx-ring-size 1024 - hw_addr is not taken due to the test for random mac is inverted - id is an integer, not a string - integer values were not converted to network format Change-Id: I5a669d702a80ad158517df46f0ab089e4d0d692e Signed-off-by: Steven <sluong@cisco.com>

2018-03-01SCTP: API to add a sub-connectionMarco Varlese7-38/+243
This patch adds an API to add a sub-connection following a SRC/DST IP mapping as required by the RFC4960. At the same time, it changes the way the next available sub-connection is being calculated: rather than having an index in the parent connection which is prone to many issues at run-time, the next available sub-connection is being calculated by looking at the state of the set sub-connections and if marked as DOWN it means that is an available slot to be used.

2018-02-28tapv2: abort in tap_create_if (VPP-1179)Steven1-0/+1
The following command sequences cause the crash: create tap id 0 rx-ring-size 1024 tx-ring-size 1024 create tap id 1 rx-ring-size 1024 tx-ring-size 1024 set interface state tap0 up set interface state tap1 up delete tap tap0 delete tap tap1 create tap id 0 rx-ring-size 1024 tx-ring-size 1024 0: /home/sluong/vpp2/vpp/build-data/../src/vnet/interface_funcs.h:46 (vnet_get_hw_interface) assertion `! pool_is_free (vnm->interface_main.hw_interfaces, _e)' fails The reason for the crash is because when the tap interface is deleted, the code does not remove the entry from the device queue. But the interface is deleted anyway from vnet_main.interface_main.hw_interfaces. When an interface is created again, it may encounter the deleted entry in the device queue and crash. Notice create and delete a single entry does not cause a crash. Need to create and delete 2 interfaces to create a "hole" in the device queue.

2018-02-25SCTP: fix connection memory corruptionMarco Varlese4-14/+23
A bug was found when multiple SCTP connections were being opened to the same SCTP server. This patch addresses that problem, removing the use of the 'parent' pointer approach for sub-connection and saving instead within the sub-connection itself the ID representing its position. That facilitates pointer-arithmetic to be computed in the get_connection_from_transport(). Change-Id: Iaa1f4efc501590be1c93e42fd6fe3d6e02f635eb Signed-off-by: Marco Varlese <marco.varlese@suse.com>
