* ofp-util, ofp-parse: Break up into many separate modules.Ben Pfaff2018-02-131-0/+15
| | | | | | | | | | | | ofp-util had been far too large and monolithic for a long time. This commit breaks it up into units that make some logical sense. It also moves the pieces of ofp-parse that were specific to each unit into the relevant unit. Most of this commit is just moving code around.

* ovs-atomic: Add C++ compatible implementation.Ben Pfaff2017-10-171-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | G++ 5 does not implement the _Atomic keyword, which is part of C11 but not C++11, so the existing <stdatomic.h> based atomic implementation doesn't work. This commit adds a new implementation based on the C++11 <atomic> header. In this area, C++ is pickier about types than C, so a few of the definitions in ovs-atomic.h have to be updated to use more precise types for integer constants. This updates the code that generates cxxtest.cc to #include <config.h> (so that HAVE_ATOMIC is defined) and to automatically regenerate when the program is reconfigured (because otherwise the #include <config.h>) won't get added without a "make clean" step). "ovs-atomic.h" is not a public header, but apparently some code was using it anyway. Fixes: 9c463631e8145 ("ovs-atomic: Report error for contradictory configuration.")

* userspace: Add support for NSH MD1 match fieldsJan Scheurich2017-08-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for NSH packet header fields to the OVS control plane and the userspace datapath. Initially we support the fields of the NSH base header as defined in https://www.ietf.org/id/draft-ietf-sfc-nsh-13.txt and the fixed context headers specified for metadata format MD1. The variable length MD2 format is parsed but the TLV context headers are not yet available for matching. The NSH fields are modelled as experimenter fields with the dedicated experimenter class 0x005ad650 proposed for NSH in ONF. The following fields are defined: NXOXM code ofctl name Size Comment ===================================================================== NXOXM_NSH_FLAGS nsh_flags 8 Bits 2-9 of 1st NSH word (0x005ad650,1) NXOXM_NSH_MDTYPE nsh_mdtype 8 Bits 16-23 (0x005ad650,2) NXOXM_NSH_NEXTPROTO nsh_np 8 Bits 24-31 (0x005ad650,3) NXOXM_NSH_SPI nsh_spi 24 Bits 0-23 of 2nd NSH word (0x005ad650,4) NXOXM_NSH_SI nsh_si 8 Bits 24-31 (0x005ad650,5) NXOXM_NSH_C1 nsh_c1 32 Maskable, nsh_mdtype==1 (0x005ad650,6) NXOXM_NSH_C2 nsh_c2 32 Maskable, nsh_mdtype==1 (0x005ad650,7) NXOXM_NSH_C3 nsh_c3 32 Maskable, nsh_mdtype==1 (0x005ad650,8) NXOXM_NSH_C4 nsh_c4 32 Maskable, nsh_mdtype==1 (0x005ad650,9) Co-authored-by: Johnson Li <johnson.li@intel.com> Signed-off-by: Yi Yang <yi.y.yang@intel.com> Signed-off-by: Jan Scheurich <jan.scheurich@ericsson.com> Signed-off-by: Ben Pfaff <blp@ovn.org>
* OF support and translation of generic encap and decapJan Scheurich2017-08-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for the OpenFlow actions generic encap and decap (as specified in ONF EXT-382) to the OVS control plane. CLI syntax for encap action with properties: encap(<header>) encap(<header>(<prop>=<value>,<tlv>(<class>,<type>,<value>),...)) For example: encap(ethernet) encap(nsh(md_type=1)) encap(nsh(md_type=2,tlv(0x1000,10,0x12345678),tlv(0x2000,20,0xfedcba9876543210))) CLI syntax for decap action: decap() decap(packet_type(ns=<pt_ns>,type=<pt_type>)) For example: decap() decap(packet_type(ns=0,type=0xfffe)) decap(packet_type(ns=1,type=0x894f)) The first header supported for encap and decap is "ethernet" to convert packets between packet_type (1,Ethertype) and (0,0). This commit also implements a skeleton for the translation of generic encap and decap actions in ofproto-dpif and adds support to encap and decap an Ethernet header. In general translation of encap commits pending actions and then rewrites struct flow in accordance with the new packet type and header. In the case of encap(ethernet) it suffices to change the packet type from (1, Ethertype) to (0,0) and set the dl_type accordingly. A new pending_encap flag in xlate ctx is set to mark that an corresponding datapath encap action must be triggered at the next commit. In the case of encap(ethernet) ofproto generetas a push_eth action. The general case for translation of decap() is to emit a datapath action to decap the current outermost header and then recirculate the packet to reparse the inner headers. In the special case of an Ethernet packet, decap() just changes the packet type from (0,0) to (1, dl_type) without a need to recirculate. The emission of the pop_eth action for the datapath is postponed to the next commit. Hence encap(ethernet) and decap() on an Ethernet packet are OF octions that only incur a cost in the dataplane when a modifed packet is actually committed, e.g. because it is sent out. They can freely be used for normalizing the packet type in the OF pipeline without degrading performance.

| | | | | | | | | | | | | | This patch is based on the "datapath: enable vxlangpe creation in compat mode" from Yi Yang. It introduces an extension option "gpe" to the vxlan port in the netdev-dpdk datapath. Description of vxlan gpe protocoll was added to header file lib/packets.h. In the vxlan specific methods the different packet are introduced and handled. Added VXLAN GPE tunnel push test.

* json: Move from lib to include/openvswitch.Terry Wilson2016-07-221-0/+3
| | | | | | | | | | | | | | | To easily allow both in- and out-of-tree building of the Python wrapper for the OVS JSON parser (e.g. w/ pip), move json.h to include/openvswitch. This also requires moving lib/{hmap,shash}.h. Both hmap.h and shash.h were #include-ing "util.h" even though the headers themselves did not use anything from there, but rather from include/openvswitch/util.h. Fixing that required including util.h in several C files mostly due to OVS_NOT_REACHED and things like xmalloc. Signed-off-by: Terry Wilson <twilson@redhat.com> Signed-off-by: Ben Pfaff <blp@ovn.org>

This removes the userspace code to set the stats and replaces it with a mechanism to access the equivalent functionality in the vport layer.
