From 6ad0fcf2f32f412091d0dfd58da1d8f5dc474809 Mon Sep 17 00:00:00 2001 From: Sander Vrijders Date: Fri, 8 Apr 2016 16:32:35 +0200 Subject: lib, irmd, irm: Add dif_config This adds dif_config to the prototype, in which one is able to specify the parameters a DIF should have. The bootstrap operation of an IPCP takes this as parameter and is oblivious to whether it is a shim or a normal IPCP. The dif_config struct is also correctly serialized and deserialized and passed opaquely to the correct IPCP. This IPCP is in charge of deserializing it correctly. --- include/ouroboros/CMakeLists.txt | 1 + include/ouroboros/common.h | 24 ---------------- include/ouroboros/dif_config.h | 61 ++++++++++++++++++++++++++++++++++++++++ include/ouroboros/ipcp.h | 10 +++++-- include/ouroboros/irm.h | 12 ++++---- include/ouroboros/sockets.h | 3 ++ include/ouroboros/utils.h | 2 ++ 7 files changed, 81 insertions(+), 32 deletions(-) create mode 100644 include/ouroboros/dif_config.h (limited to 'include') diff --git a/include/ouroboros/CMakeLists.txt b/include/ouroboros/CMakeLists.txt index 0b52a2bc..fb4884b7 100644 --- a/include/ouroboros/CMakeLists.txt +++ b/include/ouroboros/CMakeLists.txt @@ -8,6 +8,7 @@ set(HEADER_FILES common.h da.h dev.h + dif_config.h du_buff.h flow.h instance_name.h diff --git a/include/ouroboros/common.h b/include/ouroboros/common.h index 658c3618..971a382a 100644 --- a/include/ouroboros/common.h +++ b/include/ouroboros/common.h @@ -42,28 +42,4 @@ struct qos_spec { uint32_t jitter; }; -/* FIXME: What should be configurable in the DIF? */ -struct dif_config { - /* general data */ - char * dif_name; - - /* TODO: efficient policies */ - - /* dt field sizes in octets */ - uint8_t addr_size; - uint8_t cep_id_size; - uint8_t pdu_length_size; - uint8_t qos_id_size; - uint8_t seqno_size; - - /* constants for dup */ - uint8_t ttl_size; - uint8_t chk_size; - - /* values, octets */ - uint32_t min_pdu_size; - uint32_t max_pdu_size; - -}; - #endif /* OUROBOROS_COMMON_H */ diff --git a/include/ouroboros/dif_config.h b/include/ouroboros/dif_config.h new file mode 100644 index 00000000..5443085e --- /dev/null +++ b/include/ouroboros/dif_config.h @@ -0,0 +1,61 @@ +/* + * Ouroboros - Copyright (C) 2016 + * + * DIF configurations for each IPCP type + * + * Sander Vrijders + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * 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.
