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/config/lib/common.cmake | 58 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 cmake/config/lib/common.cmake (limited to 'cmake/config/lib/common.cmake') diff --git a/cmake/config/lib/common.cmake b/cmake/config/lib/common.cmake new file mode 100644 index 00000000..ebdc3196 --- /dev/null +++ b/cmake/config/lib/common.cmake @@ -0,0 +1,58 @@ +# Library configuration options for Ouroboros Options affecting libouroboros-common, +# libouroboros-dev and libouroboros-irm as a whole; per-subsystem options sit beside this file + +# Flow limits +set(SYS_MAX_FLOWS 10240 CACHE STRING + "Maximum number of total flows for this system") +set(PROC_MAX_FLOWS 4096 CACHE STRING + "Maximum number of flows in an application") +set(PROC_RES_FDS 64 CACHE STRING + "Number of reserved flow descriptors per application") +set(PROC_MAX_FQUEUES 32 CACHE STRING + "Maximum number of flow sets per application") + +# Threading +if(NOT APPLE) + set(PTHREAD_COND_CLOCK "CLOCK_MONOTONIC" CACHE STRING + "Clock to use for condition variable timing") +else() + set(PTHREAD_COND_CLOCK "CLOCK_REALTIME" CACHE INTERNAL + "Clock to use for condition variable timing") +endif() + +# Timeouts +set(SOCKET_TIMEOUT 500 CACHE STRING + "Default timeout for responses from IPCPs (ms)") + +# QoS settings +set(QOS_DISABLE_CRC TRUE CACHE BOOL + "Ignores ber setting on all QoS cubes") + +include(utils/CPUUtils) +detect_pclmul() +detect_pmull() +if(HAVE_PCLMUL) + message(STATUS "CRC-64/NVMe backend: PCLMUL (x86 SSE4.1+PCLMUL)") +elseif(HAVE_PMULL) + message(STATUS "CRC-64/NVMe backend: PMULL (aarch64 crypto)") +else() + message(STATUS "CRC-64/NVMe backend: byte table (no acceleration)") +endif() + +# Thread pool manager (TPM) debugging +set(TPM_DEBUG_REPORT_INTERVAL 0 CACHE STRING + "Interval at wich the TPM will report long running threads (s), 0 disables") +set(TPM_DEBUG_ABORT_TIMEOUT 0 CACHE STRING + "TPM abort process after a thread reaches this timeout (s), 0 disables") + +# Flow statistics (requires FUSE) +if(HAVE_FUSE) + set(PROC_FLOW_STATS TRUE CACHE BOOL + "Enable flow statistics tracking for application flows") + if(PROC_FLOW_STATS) + message(STATUS "Application flow statistics enabled") + else() + message(STATUS "Application flow statistics disabled") + endif() +endif() + -- cgit v1.2.3
