From 16f1b9ee2901404ebb5cd9d5e623bb28ffbf236a Mon Sep 17 00:00:00 2001 From: Olivier Dugeon Date: Tue, 19 Apr 2016 16:21:46 +0200 Subject: Update Traffic Engineering Support for OSPFD NOTE: I am squashing several commits together because they do not independently compile and we need this ability to do any type of sane testing on the patches. Since this series builds together I am doing this. -DBS This new structure is the basis to get new link parameters for Traffic Engineering from Zebra/interface layer to OSPFD and ISISD for the support of Traffic Engineering * lib/if.[c,h]: link parameters struture and get/set functions * lib/command.[c,h]: creation of a new link-node * lib/zclient.[c,h]: modification to the ZBUS message to convey the link parameters structure * lib/zebra.h: New ZBUS message Signed-off-by: Olivier Dugeon Add support for IEEE 754 format * lib/stream.[c,h]: Add stream_get{f,d} and stream_put{f,d}) demux and muxers to safely convert between big-endian IEEE-754 single and double binary format, as used in IETF RFCs, and C99. Implementation depends on host using __STDC_IEC_559__, which should be everything we care about. Should correctly error out otherwise. * lib/network.[c,h]: Add ntohf and htonf converter * lib/memtypes.c: Add new memeory type for Traffic Engineering support Signed-off-by: Olivier Dugeon Add link parameters support to Zebra * zebra/interface.c: - Add new link-params CLI commands - Add new functions to set/get link parameters for interface * zebra/redistribute.[c,h]: Add new function to propagate link parameters to routing daemon (essentially OSPFD and ISISD) for Traffic Engineering. * zebra/redistribute_null.c: Add new function zebra_interface_parameters_update() * zebra/zserv.[c,h]: Add new functions to send link parameters Signed-off-by: Olivier Dugeon Add support of new link-params CLI to vtysh In vtysh_config.c/vtysh_config_parse_line(), it is not possible to continue to use the ordered version for adding line i.e. config_add_line_uniq() to print Interface CLI commands as it completely break the new LINK_PARAMS_NODE. Signed-off-by: Olivier Dugeon Update Traffic Engineering support for OSPFD These patches update original code to RFC3630 (OSPF-TE) and add support of RFC5392 (Inter-AS v2) & RFC7471 (TE metric extensions) and partial support of RFC6827 (ASON - GMPLS). * ospfd/ospf_dump.[c,h]: Add new dump functions for Traffic Engineering * ospfd/ospf_opaque.[c,h]: Add new TLV code points for RFC5392 * ospfd/ospf_packet.c: Update checking of OSPF_OPTION * ospfd/ospf_vty.[c,h]: Update ospf_str2area_id * ospfd/ospf_zebra.c: Add new function ospf_interface_link_params() to get Link Parameters information from the interface to populate Traffic Engineering metrics * ospfd/ospfd.[c,h]: Update OSPF_OPTION flags (T -> MT and new DN) * ospfd/ospf_te.[c,h]: Major modifications to update the code to new link parameters structure and new RFCs Signed-off-by: Olivier Dugeon tmp --- lib/command.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'lib/command.c') diff --git a/lib/command.c b/lib/command.c index 10ab066bfb..0e921bd636 100644 --- a/lib/command.c +++ b/lib/command.c @@ -2537,8 +2537,12 @@ node_parent ( enum node_type node ) case KEYCHAIN_KEY_NODE: ret = KEYCHAIN_NODE; break; + case LINK_PARAMS_NODE: + ret = INTERFACE_NODE; + break; default: ret = CONFIG_NODE; + break; } return ret; @@ -2926,6 +2930,9 @@ DEFUN (config_exit, case KEYCHAIN_KEY_NODE: vty->node = KEYCHAIN_NODE; break; + case LINK_PARAMS_NODE: + vty->node = INTERFACE_NODE; + break; default: break; } @@ -2975,6 +2982,7 @@ DEFUN (config_end, case MASC_NODE: case PIM_NODE: case VTY_NODE: + case LINK_PARAMS_NODE: vty_config_unlock (vty); vty->node = ENABLE_NODE; break; -- cgit v1.2.3
