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 --- cmake/dependencies/udp/ddns.cmake | 31 ------------------------------- 1 file changed, 31 deletions(-) delete mode 100644 cmake/dependencies/udp/ddns.cmake (limited to 'cmake/dependencies/udp/ddns.cmake') diff --git a/cmake/dependencies/udp/ddns.cmake b/cmake/dependencies/udp/ddns.cmake deleted file mode 100644 index e8208e47..00000000 --- a/cmake/dependencies/udp/ddns.cmake +++ /dev/null @@ -1,31 +0,0 @@ -# DDNS (Dynamic DNS) support detection -# Requires nsupdate and nslookup tools - -find_program(NSUPDATE_EXECUTABLE - NAMES nsupdate - DOC "The nsupdate tool that enables DDNS") - -find_program(NSLOOKUP_EXECUTABLE - NAMES nslookup - DOC "The nslookup tool that resolves DNS names") - -mark_as_advanced(NSLOOKUP_EXECUTABLE NSUPDATE_EXECUTABLE) - -if(NSLOOKUP_EXECUTABLE AND NSUPDATE_EXECUTABLE) - set(DISABLE_DDNS FALSE CACHE BOOL "Disable DDNS support") - if(NOT DISABLE_DDNS) - message(STATUS "DDNS support enabled") - set(HAVE_DDNS TRUE CACHE INTERNAL "Dynamic DNS support available") - else() - message(STATUS "DDNS support disabled by user") - unset(HAVE_DDNS CACHE) - endif() -else() - if(NSLOOKUP_EXECUTABLE) - message(STATUS "Install nsupdate to enable DDNS support") - elseif(NSUPDATE_EXECUTABLE) - message(STATUS "Install nslookup to enable DDNS support") - else() - message(STATUS "Install nslookup and nsupdate to enable DDNS support") - endif() -endif() -- cgit v1.2.3
