An AE can then use the connection manager to allocate a flow to a neighbor, or to wait for a new connection from a neighbor. --- include/ouroboros/cacep.h | 7 +- src/ipcpd/ipcp.h | 2 +- src/ipcpd/normal/CMakeLists.txt | 1 + src/ipcpd/normal/connmgr.c | 350 ++++++++++++++++++++++++++++++++++++++++ src/ipcpd/normal/connmgr.h | 57 +++++++ src/ipcpd/normal/enroll.c | 2 +- src/ipcpd/normal/fmgr.c | 2 +- src/ipcpd/normal/frct.c | 8 +- src/ipcpd/normal/gam.c | 4 +- src/ipcpd/normal/main.c | 93 +++-------- src/ipcpd/normal/pol/complete.c | 13 +- src/lib/cacep.c | 3 + src/lib/cacep.proto | 1 + 13 files changed, 452 insertions(+), 91 deletions(-) create mode 100644 src/ipcpd/normal/connmgr.c create mode 100644 src/ipcpd/normal/connmgr.h (limited to 'src') diff --git a/include/ouroboros/cacep.h b/include/ouroboros/cacep.h index c7b7f38c..b6fb8625 100644 --- a/include/ouroboros/cacep.h +++ b/include/ouroboros/cacep.h @@ -32,15 +32,12 @@ enum proto_concrete_syntax { PROTO_FIXED }; -struct conn_info{ +struct conn_info { char ae_name[64]; char protocol[64]; uint32_t pref_version; enum proto_concrete_syntax pref_syntax; - union { - char name[64]; - uint64_t addr; - } ae; + uint64_t addr; }; int cacep_snd(int fd, diff --git a/src/ipcpd/ipcp.h b/src/ipcpd/ipcp.h index d0b5e022..07c72791 100644 --- a/src/ipcpd/ipcp.h +++ b/src/ipcpd/ipcp.h @@ -65,7 +65,7 @@ struct ipcp { enum ipcp_type type; char * dif_name; - uint64_t address; + uint64_t dt_addr; struct ipcp_ops * ops; int irmd_fd; diff --git a/src/ipcpd/normal/CMakeLists.txt b/src/ipcpd/normal/CMakeLists.txt index 7e10cc0d..70742336 100644 --- a/src/ipcpd/normal/CMakeLists.txt +++ b/src/ipcpd/normal/CMakeLists.txt @@ -20,6 +20,7 @@ set(SOURCE_FILES # Add source files here addr_auth.c cdap_flow.c + connmgr.c dir.c enroll.c fmgr.c diff --git a/src/ipcpd/normal/connmgr.c b/src/ipcpd/normal/connmgr.c new file mode 100644 index 00000000..387c38fd --- /dev/null +++ b/src/ipcpd/normal/connmgr.c @@ -0,0 +1,350 @@ +/* + * Ouroboros - Copyright (C) 2016 - 2017 + * + * Handles the different AP connections + * + * Sander Vrijders + * Dimitri Staessens + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

They all listen to and use the connection manager to establish new application connections. This commit also adds a neighbors struct to the normal IPCP. It contains neighbor structs that contain application connection. Notifiers can be registered in case a neighbor changes (added, removed, QoS changed). The flow manager has an instance of this neighbors struct and listens to these events to update its flow set. The routing component also listens to these events so that it can update the FSDB if needed. The flow manager now also creates the PFF instances and the routing instances per QoS cube. The RIB manager also uses this an instance of the neighbors struct and listens to neighbor events as well. --- src/ipcpd/normal/CMakeLists.txt | 2 + src/ipcpd/normal/connmgr.c | 8 +- src/ipcpd/normal/connmgr.h | 2 +- src/ipcpd/normal/enroll.c | 292 +++++++++++++++++++++++---------------- src/ipcpd/normal/enroll.h | 10 +- src/ipcpd/normal/fmgr.c | 283 +++++++++++++++++++++++--------------- src/ipcpd/normal/fmgr.h | 4 - src/ipcpd/normal/frct.c | 16 +-- src/ipcpd/normal/frct.h | 2 + src/ipcpd/normal/gam.c | 296 +++------------------------------------- src/ipcpd/normal/gam.h | 21 +-- src/ipcpd/normal/main.c | 54 ++++++-- src/ipcpd/normal/neighbors.c | 213 +++++++++++++++++++++++++++++ src/ipcpd/normal/neighbors.h | 81 +++++++++++ src/ipcpd/normal/pff.c | 7 +- src/ipcpd/normal/pff.h | 4 +- src/ipcpd/normal/pol-gam-ops.h | 14 +- src/ipcpd/normal/pol/complete.c | 189 ++++++++++--------------- src/ipcpd/normal/pol/complete.h | 29 ++-- src/ipcpd/normal/ribconfig.h | 2 + src/ipcpd/normal/ribmgr.c | 84 +++++++++--- src/ipcpd/normal/ribmgr.h | 3 - src/ipcpd/normal/routing.c | 132 ++++++++++++++++++ src/ipcpd/normal/routing.h | 42 ++++++ 24 files changed, 1065 insertions(+), 725 deletions(-) create mode 100644 src/ipcpd/normal/neighbors.c create mode 100644 src/ipcpd/normal/neighbors.h create mode 100644 src/ipcpd/normal/routing.c create mode 100644 src/ipcpd/normal/routing.h (limited to 'src') diff --git a/src/ipcpd/normal/CMakeLists.txt b/src/ipcpd/normal/CMakeLists.txt index 70742336..772d5212 100644 --- a/src/ipcpd/normal/CMakeLists.txt +++ b/src/ipcpd/normal/CMakeLists.txt @@ -27,8 +27,10 @@ set(SOURCE_FILES frct.c gam.c main.c + neighbors.c pff.c ribmgr.c + routing.c shm_pci.c # Add policies last pol/complete.c diff --git a/src/ipcpd/normal/connmgr.c b/src/ipcpd/normal/connmgr.c index 387c38fd..0c908cd1 100644 --- a/src/ipcpd/normal/connmgr.c +++ b/src/ipcpd/normal/connmgr.c @@ -42,8 +42,6 @@ #include #include -#define FRCT_PROTO "frct" - struct ae_conn { struct list_head next;

This will simplify sending messages to different peers (e.g. for syncing the RIB). A request will now return an array of keys terminated by CDAP_KEY_INVALID.

The graph that is kept within the routing component is updated depending on the event that was received. --- src/ipcpd/normal/CMakeLists.txt | 3 +- src/ipcpd/normal/fso.proto | 29 +++++++ src/ipcpd/normal/routing.c | 184 +++++++++++++++++++++++++++++++++------- 3 files changed, 182 insertions(+), 34 deletions(-) create mode 100644 src/ipcpd/normal/fso.proto (limited to 'src') diff --git a/src/ipcpd/normal/CMakeLists.txt b/src/ipcpd/normal/CMakeLists.txt index 39ced7bc..06292c50 100644 --- a/src/ipcpd/normal/CMakeLists.txt +++ b/src/ipcpd/normal/CMakeLists.txt @@ -15,6 +15,7 @@ include_directories(${CMAKE_BINARY_DIR}/include) set(IPCP_NORMAL_TARGET ipcpd-normal CACHE STRING "IPCP_NORMAL_TARGET") protobuf_generate_c(FLOW_ALLOC_SRCS FLOW_ALLOC_HDRS flow_alloc.proto) +protobuf_generate_c(FSO_SRCS FSO_HDRS fso.proto) set(SOURCE_FILES # Add source files here @@ -38,7 +39,7 @@ set(SOURCE_FILES ) add_executable(ipcpd-normal ${SOURCE_FILES} ${IPCP_SOURCES} - ${FLOW_ALLOC_SRCS}) + ${FLOW_ALLOC_SRCS} ${FSO_SRCS}) target_link_libraries(ipcpd-normal LINK_PUBLIC ouroboros) include(AddCompileFlags) diff --git a/src/ipcpd/normal/fso.proto b/src/ipcpd/normal/fso.proto new file mode 100644 index 00000000..32b281d6 --- /dev/null +++ b/src/ipcpd/normal/fso.proto @@ -0,0 +1,29 @@ +/* + * Ouroboros - Copyright (C) 2016 - 2017 + * + * Flow State Object message + * + * Dimitri Staessens + * Sander Vrijders + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
