From 980ebd25794f0f87ac32844e2c73e9e81f0a72ba Mon Sep 17 00:00:00 2001 From: Jamal Hadi Salim Date: Mon, 20 Mar 2006 19:16:40 -0800 Subject: [IPSEC]: Sync series - acquire insert This introduces a feature similar to the one described in RFC 2367: " ... the application needing an SA sends a PF_KEY SADB_ACQUIRE message down to the Key Engine, which then either returns an error or sends a similar SADB_ACQUIRE message up to one or more key management applications capable of creating such SAs. ... ... The third is where an application-layer consumer of security associations (e.g. an OSPFv2 or RIPv2 daemon) needs a security association. Send an SADB_ACQUIRE message from a user process to the kernel. The kernel returns an SADB_ACQUIRE message to registered sockets. The user-level consumer waits for an SADB_UPDATE or SADB_ADD message for its particular type, and then can use that association by using SADB_GET messages. " An app such as OSPF could then use ipsec KM to get keys Signed-off-by: Jamal Hadi Salim Signed-off-by: David S.
