ipcpd: Add ipcpd over UDP/IPv6

2025-09-10T06:19:52+00:00

This adds an IPCP that runs over UDP/IPv6. It's structured like the eth-dix and eth-llc in that it builds two separate binaries: ipcpd-udp4 and ipcpd-udp6. The IRM CLI is backwards compatible in that type 'udp' will resolve to type 'udp4'. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Initial Flow Allocation Protocol Header

2025-07-23T13:07:52+00:00

This adds the initial version for the flow allocation protocol header between IRMd instances. This is a step towards flow authentication. The header supports secure and authenticated flow allocation, supporting certificate-based authentication and ephemeral key exchange for end-to-end encryption. id: 128-bit identifier for the entity. timestamp: 64-bit timestamp (replay protection). certificate: Certificate for authentication. public key: ECDHE public key for key exchange. data: Application data. signature: Signature for integrity/authenticity. Authentication and encryption require OpenSSL to be installed. The IRMd compares the allocation request delay with the MPL of the Layer over which the flow allocation was sent. MPL is now reported by the Layer in ms instead of seconds. Time functions revised for consistency and adds some tests. The TPM can now print thread running times in Debug builds (TPM_DEBUG_REPORT_INTERVAL) and abort processes with hung threads (TPM_DEBUG_ABORT_TIMEOUT). Long running threads waiting for input should call tpm_wait_work() to avoid trigger a process abort. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipdpd: Pass MPL to application at flow_allocation

2022-03-08T16:40:17+00:00

The maximum packet lifetime (MPL) is a property of the flow that needs to be passed to the reliable transmission protocol (FRCP) for its correct operation. Previously, the value of MPL was set fixed as one of the (fixed) Delta-t parameters. This patch makes the MPL a property of the layer, and it can now be set per layer-type at build time. This is a step towards a proper MPL estimator in the flow allocator. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Set specific compiler flags for SWIG target

2019-03-21T11:33:54+00:00

The compiler flags for the SWIG target were added to the global CMAKE_C_FLAGS used for the entire project. This sets the flags uniquely for the SWIG target. The eth has a similar case for the c99 flag. There was a lingering include in dev.c that was removed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Restrict MTU for Ethernet over loopback

2019-03-21T08:42:34+00:00

This restricts the MTU for the Ethernet IPCP over loopback adapters (devices named "lo*") to avoid it allocating 65K buffers per packet and quickly filling the default RDRBUFF space. The restriction is set using the build option IPCP_ETH_LO_MTU, with a default value of 1500 bytes. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Set default number of threads in eth to 1

2019-03-05T08:10:38+00:00

This makes the eth packet handler single-threaded by default, at least until stability issues that seem to be related to multi-threading are fixed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Make Qdisc bypass configurable

2018-10-12T15:30:49+00:00

This will make bypassing the qdisc configurable, as it might be handy for getting fast data rates but is generally needed. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

build: Prioritize raw socket API in build

2018-10-03T13:18:58+00:00

This will change the build to exclusively select one raw socket API in case multiple are present in the sytem, which will simplify the code. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Fix build for netmap enabled Ethernet IPCP

2018-10-03T09:00:56+00:00

There were some compilation issues introduced by adding the interface monitor to the Ethernet IPCP. Furthermore it was not possible to select between raw sockets or netmap if both were available. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Add multithreading to Ethernet IPCP

2018-10-03T07:14:57+00:00

This adds multiple reader and writer threads, configurabe via cmake with IPCP_ETH_RD_THR and IPCP_ETH_WR_THR. Improves ethernet IPCP throughput, which looks to be limited by the raw socket calls. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
