From adc6766221327f99ab484d66f6f92050ec9e62d7 Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Tue, 21 Feb 2017 08:02:37 +0100 Subject: lib: Exchange protocol info during CACEP This exchanges a protocol name, a protocol version and concrete syntax for the protocol upon CACEP. For CDAP, only version 1 and GPB are supported. No lists for other supported versions or syntaxes are exchanged (but the proto file supports it). CACEP fails if there is a mismatch between the protocol names, version and syntax specified by the communicating parties. --- include/ouroboros/cacep.h | 15 +++++++++++++++ include/ouroboros/cdap.h | 1 + 2 files changed, 16 insertions(+) (limited to 'include') diff --git a/include/ouroboros/cacep.h b/include/ouroboros/cacep.h index 63418bd3..e0737c47 100644 --- a/include/ouroboros/cacep.h +++ b/include/ouroboros/cacep.h @@ -26,12 +26,27 @@ #include +enum proto_concrete_syntax { + PROTO_GPB = 0, + PROTO_ASN_1, + PROTO_FIXED +}; + struct cacep_info { + struct { + char * protocol; + uint32_t pref_version; + enum proto_concrete_syntax pref_syntax; + } proto; char * name; uint64_t addr; void * data; }; +int cacep_info_init(struct cacep_info * info); + +void cacep_info_fini(struct cacep_info * info); + struct cacep_info * cacep_auth(int fd, enum pol_cacep pc, const struct cacep_info * info); diff --git a/include/ouroboros/cdap.h b/include/ouroboros/cdap.h index 9f6e2654..cc04cf27 100644 --- a/include/ouroboros/cdap.h +++ b/include/ouroboros/cdap.h @@ -31,6 +31,7 @@ #define F_SYNC 0x0001 #define INVALID_CDAP_KEY -1 +#define CDAP_PROTO "CDAP" enum cdap_opcode { CDAP_READ = 0, -- cgit v1.2.3
