From 24aa46946349529bf36d3569796a28917d3e756f Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Wed, 9 Aug 2017 18:55:37 +0200 Subject: build, lib, ipcpd, irmd: Add support for libgcrypt This adds support for libgcrypt. If at least version 1.7.0 of libgcrypt is present, it may be used for secure random number generation and is used for hashing in the irmd/ipcp. The hash definitions are moved to the internal hash.h header, and defined independently of the hashes that are defined as part of the directory policy for the normal IPCP. The translation is moved from the IRMd to ipcpd/ipcp.h. The bootstrap call from the IRMd expects the IPCP to return the correct hash algorithm with a dif_info struct, which is in line with the behavior of the enroll call. This also improves how some platform checks in the build system are handled. --- src/ipcpd/ipcp.c | 53 ++++++++++++++++++++++++++++++++++++++++++++--------- 1 file changed, 44 insertions(+), 9 deletions(-) (limited to 'src/ipcpd/ipcp.c') diff --git a/src/ipcpd/ipcp.c b/src/ipcpd/ipcp.c index 48ff046c..b2afdf99 100644 --- a/src/ipcpd/ipcp.c +++ b/src/ipcpd/ipcp.c @@ -23,6 +23,7 @@ #define OUROBOROS_PREFIX "ipcpd/ipcp" #include +#include #include #include #include @@ -174,7 +175,7 @@ static void * mainloop(void * o) strcpy(conf.dif_info.dif_name, conf_msg->dif_info->dif_name); if (conf.dif_info.dif_name == NULL) { - ret_msg.has_result = true; + log_err("No DIF name provided."); ret_msg.result = -1; break; } @@ -186,21 +187,55 @@ static void * mainloop(void * o) conf.dt_gam_type = conf_msg->dt_gam_type; conf.rm_gam_type = conf_msg->rm_gam_type; conf.routing_type = conf_msg->routing_type; - conf.dif_info.dir_hash_algo = - conf_msg->dif_info->dir_hash_algo; + + switch(conf_msg->dif_info->dir_hash_algo) { + case DIR_HASH_SHA3_224: + conf.dif_info.dir_hash_algo + = HASH_SHA3_224; + break; + case DIR_HASH_SHA3_256: + conf.dif_info.dir_hash_algo + = HASH_SHA3_256; + break; + case DIR_HASH_SHA3_384: + conf.dif_info.dir_hash_algo + = HASH_SHA3_384; + break; + case DIR_HASH_SHA3_512: + conf.dif_info.dir_hash_algo + = HASH_SHA3_512; + break; + default: + assert(false); + } + + dif_info.dir_hash_algo = + conf.dif_info.dir_hash_algo; } if (conf_msg->ipcp_type == IPCP_SHIM_UDP) { - conf.ip_addr = conf_msg->ip_addr; - conf.dns_addr = conf_msg->dns_addr; + conf.ip_addr = conf_msg->ip_addr; + conf.dns_addr = conf_msg->dns_addr; + dif_info.dir_hash_algo = HASH_MD5; + ipcpi.dir_hash_algo = HASH_MD5; } - if (conf_msg->ipcp_type == IPCP_SHIM_ETH_LLC) - conf.if_name = conf_msg->if_name; + if (conf_msg->ipcp_type == IPCP_SHIM_ETH_LLC) { + conf.if_name = conf_msg->if_name; + dif_info.dir_hash_algo = HASH_SHA3_256; + ipcpi.dir_hash_algo = HASH_SHA3_256; + } - ipcpi.dir_hash_algo = conf_msg->dif_info->dir_hash_algo; + if (conf_msg->ipcp_type == IPCP_LOCAL) { + dif_info.dir_hash_algo = HASH_SHA3_256; + ipcpi.dir_hash_algo = HASH_SHA3_256; + } ret_msg.result = ipcpi.ops->ipcp_bootstrap(&conf); + if (ret_msg.result == 0) { + ret_msg.dif_info = &dif_info; + dif_info.dif_name = conf.dif_info.dif_name; + } break; case IPCP_MSG_CODE__IPCP_ENROLL: ret_msg.has_result = true; @@ -220,7 +255,7 @@ static void * mainloop(void * o) ret_msg.result = ipcpi.ops->ipcp_enroll(msg->dst_name, &info); if (ret_msg.result == 0) { - ret_msg.dif_info = &dif_info; + ret_msg.dif_info = &dif_info; dif_info.dir_hash_algo = info.dir_hash_algo; dif_info.dif_name = info.dif_name; } -- cgit v1.2.3
