From 5c239c128c04883dbed6d66f574edf8b48d11e11 Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Sun, 16 Aug 2026 18:55:15 +0000 Subject: lib: Replace shim IPCPs with points of attachment Removes the UDP and Ethernet shim IPCPs. The unicast and broadcast IPCPs can now directly attach to a "legacy" socket. We adopt Saltzer's Point-of-Attachment terminology, also advocated in Day's "Patterns in Network Architecture". The "poa" component manages these PoA's with one management thread, one link monitoring thread and one thread per attached point. For Ethernet PoA's the irm connect and enroll can resolve the destination IPCP or Layer name with a broadcast name query over the attached PoAs (first reply wins). UDP PoA's require a destination IP address or FQDN. attach to a local endpoint (required both server and client side): irm ipcp poa attach name a udp 10.0.0.1 irm ipcp poa attach name a udp 10.0.0.1:3435 irm ipcp poa attach name a udp [::1]:3435 irm ipcp poa attach name a eth dev eth0 irm ipcp poa attach name a eth dev eth0 ethertype 0xA000 release a PoA (refused while it carries a flow): irm ipcp poa detach name a udp 10.0.0.1:3435 irm ipcp poa detach name a eth eth0 list an IPCP's PoAs: irm ipcp poa list name a connect to a peer, by name or at an address: irm ipcp connect name b dst a irm ipcp connect name b dst a eth irm ipcp connect name b dst a eth dev eth0 irm ipcp connect name b dst a udp 10.0.0.1:3435 irm ipcp connect name b dst a udp peer.example.com:3435 disconnect by peer name, no address: irm ipcp disconnect name b dst a irm ipcp disconnect name b dst a component mgmt enroll has the same shape as connect: irm ipcp enroll name b layer lr autobind irm ipcp enroll name b layer lr autobind eth dev eth0 irm ipcp enroll name b layer lr autobind udp 10.0.0.1:3435 the IRMd config file attaches PoAs and names peers the same way: udp = [ "10.0.0.1", "10.0.0.1:3436" ] eth = [ "eth0", {dev="eth1", ethertype=0xA007} ] enrol={dst="LAN", eth={dev="eth0"}} conn=[{dst="lan3", eth={}}, {dst="lan4", udp="10.0.0.1:3435"}] Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders --- src/irmd/irmd.h | 53 ++++++++++++++++++++++++++++++++++++----------------- 1 file changed, 36 insertions(+), 17 deletions(-) (limited to 'src/irmd/irmd.h') diff --git a/src/irmd/irmd.h b/src/irmd/irmd.h index f88378ad..9d42e248 100644 --- a/src/irmd/irmd.h +++ b/src/irmd/irmd.h @@ -26,29 +26,48 @@ #include #include -int create_ipcp(struct ipcp_info * info); +int create_ipcp(struct ipcp_info * info); -int bootstrap_ipcp(pid_t pid, - struct ipcp_config * conf); +int bootstrap_ipcp(pid_t pid, + struct ipcp_config * conf); -int enroll_ipcp(pid_t pid, - const char * dst); +int enroll_ipcp(pid_t pid, + const char * dst, + const struct poa_addr * addr); -int connect_ipcp(pid_t pid, - const char * dst, - const char * component, - qosspec_t qs); +int enroll_ipcp_resolve(pid_t pid, + const char * dst, + struct poa_addr * addr); -int name_create(struct name_info * info); +int attach_ipcp(pid_t pid, + const struct poa_spec * poa, + bool attach); -int name_reg(const char * name, - pid_t pid); +ssize_t list_poas(pid_t pid, + struct poa_spec ** eps); -int bind_process(pid_t pid, - const char * name); +int connect_ipcp(pid_t pid, + const char * dst, + const char * component, + qosspec_t qs, + const struct poa_addr * addr); -int bind_program(char ** exec, - const char * name, - uint8_t flags); +int connect_ipcp_resolve(pid_t pid, + const char * dst, + const char * component, + qosspec_t qs, + struct poa_addr * addr); + +int name_create(struct name_info * info); + +int name_reg(const char * name, + pid_t pid); + +int bind_process(pid_t pid, + const char * name); + +int bind_program(char ** exec, + const char * name, + uint8_t flags); #endif /* OUROBOROS_IRMD_H*/ -- cgit v1.2.3
