2019-07-26dhcp ip: DSCP settings for transmitted DHCP packetsNeale Ranns1-0/+17
Type: feature - Define the ip_dscp_t and use in the IP headers - Add DSCP setting to the DHCP client for use with packet TX Change-Id: If220dde0017ea78793747d65f53e11daf23a28fa Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-05-28Punt: socket register for exception dispatched/punted packets based on reasonNeale Ranns1-0/+16
- add to the Punt API to allow different descriptions of the desired packets: UDP or exceptions - move the punt nodes into punt_node.c - improve tests (test that the correct packets are punted to the registered socket) Change-Id: I1a133dec88106874993cba1f5a439cd26b2fef72 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-11-01session: add support for proxying appsFlorin Coras1-1/+3
To enable this, applications set the proxy flag in their attach requests and pass the transport protocols they want to act as proxies for as part of the attach options. When proxy is enabled, session rules that point incoming packets to the proxy app are addedd to the local and global session tables, if these scopes are accessible to the app. In particular, in case of the former, the rule accepts packets from all sources and all ports destined to the namespace's supporting interface address on any port. While in case of the latter, a generic any destination and any port rule is addedd. Change-Id: I791f8c1cc083350f02e26a2ac3bdbbfbfa19ece3 Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-10-28session: rules tablesFlorin Coras1-0/+108
This introduces 5-tuple lookup tables that may be used to implement custom session layer actions at connection establishment time (session layer perspective). The rules table build mask-match-action lookup trees that for a given 5-tuple key return the action for the first longest match. If rules overlap, ordering is established by tuple longest match with the following descending priority: remote ip, local ip, remote port, local port. At this time, the only match action supported is to forward packets to the application identified by the action.

2017-10-10session: add support for application namespacingFlorin Coras1-0/+124
Applications are now provided the option to select the namespace they are to be attached to and the scope of their attachement. Application namespaces are meant to: 1) constrain the scope of communication through the network by association with source interfaces and/or fib tables that provide the source ips to be used and limit the scope of routing 2) provide a namespace local scope to session layer communication, as opposed to the global scope provided by 1). That is, sessions can be established without assistance from transport and network layers. Albeit, zero/local-host ip addresses must still be provided in session establishment messages due to existing application idiosyncrasies. This mode of communication uses shared-memory fifos (cut-through sessions) exclusively. If applications request no namespace, they are assigned to the default one, which at its turn uses the default fib. Applications can request access to both local and global scopes for a namespace. If no scope is specified, session layer defaults to the global one. When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY) binds are converted to binds to the requested interface.
