2018-08-17VPP-1392: VXLAN fails with IP fragmentationOle Troan1-1/+1
Not only is it wasteful to send all fragments back through ip4-lookup, but it doesn't work with tunnel mechanisms that don't have IP enabled on their payload side. Change-Id: Ic92d95982dddaa70969a2a6ea2f98edec7614425 Signed-off-by: Ole Troan <ot@cisco.com>
2018-07-21fix IP directed broadcast node declarationsMatthew Smith1-1/+1
The dev build ('make build') was failing because ip4_rewrite_bcast() and ip6_rewrite_bcast() are declared static and were not referenced. The node functions that were set for directed broadcast rewrite: ip4_rewrite_bcast_node - ip4_rewrite() ip6_rewrite_bcast_node - ip6_rewrite() Changed to: ip4_rewrite_bcast_node - ip4_rewrite_bcast() ip6_rewrite_bcast_node - ip6_rewrite_bcast() The release build ('make build-release') succeeds because there is a VLIB_NODE_FUNCTION_MULTIARCH() call referencing the function. That macro is empty for dev builds. Change-Id: I2a05f00ca43d0eae8ff2e3026991e69917003fe1 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-0/+6
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.

2017-10-10session: add support for application namespacingFlorin Coras1-0/+26
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.
