From 7834e92b218da69cd934679dec9c2d714d89d15e Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Mon, 13 Jun 2016 13:48:17 +0200 Subject: lib, irmd, tools, ipcpd: updates to dev API. The registration function has been moved to the irm tool, applications now need to be registered by an administrator. Currently only supports one instance per registered name, and an AP can be registered under only one name. The irmd can now start a registered server application on demand. For the full functionality of the tool, execute "irm register". AP name removed from flow allocation. Flow allocation does not send the source ap name as it is quite useless. The accept() call now only returns the AE name. --- include/ouroboros/dev.h | 6 +- include/ouroboros/ipcp.h | 2 - include/ouroboros/irm.h | 18 ++- include/ouroboros/utils.h | 3 + src/ipcpd/ipcp-ops.h | 1 - src/ipcpd/ipcp.c | 1 - src/ipcpd/local/main.c | 6 +- src/ipcpd/shim-udp/main.c | 12 +- src/ipcpd/shim-udp/shim_udp_messages.proto | 1 - src/irmd/main.c | 251 ++++++++++++++++------------- src/lib/dev.c | 123 +------------- src/lib/ipcp.c | 8 +- src/lib/irm.c | 72 ++++++--- src/lib/irmd_messages.proto | 39 ++--- src/lib/utils.c | 18 +++ src/tools/cbr/cbr.c | 42 +++-- src/tools/cbr/cbr_client.c | 16 +- src/tools/cbr/cbr_server.c | 30 +--- src/tools/echo/echo.c | 19 ++- src/tools/echo/echo_client.c | 11 +- src/tools/echo/echo_server.c | 32 +--- src/tools/irm/CMakeLists.txt | 4 +- src/tools/irm/irm.c | 5 +- src/tools/irm/irm_ops.h | 4 +- src/tools/irm/irm_register.c | 123 ++++++++++++++ src/tools/irm/irm_register_ipcp.c | 79 --------- src/tools/irm/irm_unregister.c | 116 +++++++++++++ src/tools/irm/irm_unregister_ipcp.c | 80 --------- 28 files changed, 550 insertions(+), 572 deletions(-) create mode 100644 src/tools/irm/irm_register.c delete mode 100644 src/tools/irm/irm_register_ipcp.c create mode 100644 src/tools/irm/irm_unregister.c delete mode 100644 src/tools/irm/irm_unregister_ipcp.c diff --git a/include/ouroboros/dev.h b/include/ouroboros/dev.h index 506fa789..1f664d35 100644 --- a/include/ouroboros/dev.h +++ b/include/ouroboros/dev.h @@ -36,12 +36,8 @@ int ap_init(char * ap_name);
