2017-10-10session: add support for application namespacingFlorin Coras1-0/+39
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.

2017-08-25tcp: retransmit and multi-buffer segment fixes and improvementsFlorin Coras1-1/+1
- set session state as closed on session manager delete - enable retransmit as opposed to persist timer after persist timer completes - properly discard buffer chain bytes when new data overlaps ooo segments - don't use rxt bytes in snd space estimate used on tx path Change-Id: Id9cab686e532e5fe70c775d5440260e8eb890a9f Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-08-16tcp: improve builtin http serverFlorin Coras1-7/+1
Additionally: - remove opaques from stream_session_t - ensure first segment manager is only used once per app. Change-Id: I143d1fdb8effc88815ef969b78122ba3ac29e06e Signed-off-by: Florin Coras <fcoras@cisco.com>
