From 8d24b6899d0aba52fef8c48921ce4d1481ee212c Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Thu, 18 Nov 1999 14:41:29 +0000 Subject: Allow EA type to be set to 'undefined' which overrides all further definitons of that EA in the same list and causes ea_find() to fail unless you add EA_ALLOW_UNDEF to the second argument. ea_sort (resp. ea_do_prune()) removes all undef'd attributes from the list. I hope this works :) --- nest/route.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'nest/route.h') diff --git a/nest/route.h b/nest/route.h index 799e0a21..e79affbd 100644 --- a/nest/route.h +++ b/nest/route.h @@ -265,12 +265,16 @@ typedef struct eattr { #define EA_PROTO(ea) ((ea) >> 8) #define EA_ID(ea) ((ea) & 0xff) +#define EA_CODE_MASK 0xffff +#define EA_ALLOW_UNDEF 0x10000 /* ea_find: allow EAF_TYPE_UNDEF */ + #define EAF_TYPE_MASK 0x0f /* Mask with this to get type */ #define EAF_TYPE_INT 0x01 /* 32-bit signed integer number */ #define EAF_TYPE_OPAQUE 0x02 /* Opaque byte string (not filterable) */ #define EAF_TYPE_IP_ADDRESS 0x04 /* IP address [FIXME: embed at least for IPv4?] */ #define EAF_TYPE_AS_PATH 0x06 /* BGP AS path [FIXME: define storage layout] */ #define EAF_TYPE_INT_SET 0x0a /* Set of integers (e.g., a community list) */ +#define EAF_TYPE_UNDEF 0x0f /* `force undefined' entry */ #define EAF_EMBEDDED 0x01 /* Data stored in eattr.u.data (part of type spec) */ #define EAF_VAR_LENGTH 0x02 /* Attribute length is variable */ #define EAF_INLINE 0x80 /* Copy of an attribute inlined in rte (temporary ea_lists only) */ -- cgit v1.2.3
