2017-10-10session: add support for application namespacingFlorin Coras1-226/+633
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.

2017-09-18Fixes for issues Coverity has reported (VPP-972)Chris Luke1-4/+4
177117: fstat() returns -1 on error; the code is checking for any positive value instead 175142: final return could never be reached; simple refactoring 175235,175236: Warning suppressed with an explicit cast to (void) 174817: Final return couldn't be reached; is is_in_order is 0 then 'rv' is already returned above 172095,172093: If is_is_set does not get set to 1, then return 0 has already been invoked 174405: Re-kill this (nothing sets rv) 171136: Looks like a cmd line flag to set test_bytes was missing; added it, and refactored the argc/argv processing to avoid two other potential segv's 176813: Add range checking for term width/height. First stab at a reasonable range is 1-512 for both. 175350: Fix implicit casting in shift operation 174272: Not a c+p error; try using a coverity annotation to ignore it 174273,175320: Annotated FORWARD_NULL Change-Id: I58d0f860fc2209f59f8d1b6b344d631b8d429ace Signed-off-by: Chris Luke <chrisy@flirble.org>

2017-07-30Make tcp active open data structures thread safeFlorin Coras1-63/+40
- Cleanup half-open connections and timers on the right thread - Ensure half-open connection and transport endpoint pools are thread safe - Enqueue TX events to the correct vpp thread in the builtin client - Use transport proto in transport connections instead of session type Change-Id: Id13239a206afbff6f34a38afa510fe014e4b2049 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
