ipcpd: Fix strict aliasing warning

2019-03-18T20:00:59+00:00

Some versions of gcc seem to give a positive on the strict aliasing rule. It's absent from newer gcc versions or clang. However, rather than disabling the check for older version, this small rewrite seems to temporarily fix the false positive. Apparently, it's undefined behaviour to simply cast a char/uint8_t buffer to a variable type pointer and then dereference the type. A more elaborate patch to fix the undefined behaviour is needed.

build: Fix CMake policy setting

2019-03-18T20:00:29+00:00

The CMake policy setting was set to 3.13, which doesn't work on older CMake versions. The setting is now set to use the default policy of the installed version. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

doc: Update documentation to new website URL

2019-03-18T10:09:32+00:00

The documentation and package point to the imec site, which is now moved to ouroboros.rocks Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Fix build error with swig

2019-03-18T10:09:31+00:00

There is an unsafe strncpy() in the swig compilation process, which has been fixed a while back but is still not in the release version. This disables the compiler warning. It also fixes an unspecified option. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Revise UDP IPCP

2019-03-18T10:09:31+00:00

The UDP IPCP now uses a fixed server UDP port (default 3435) for all communications. This allows passing firewalls more easily since only a single port needs to be opened. The client port can be fixed as well if needed (default random). It uses an internal eid, so the MTU of the UDP layer is reduced by 4 bytes, similar to the Ethernet IPCPs.

irmd: Don't destroy shm_flow_set from IRMd

2019-03-12T08:18:51+00:00

The shm_flow_set for the processes are now created and destroyed together with the irm_flow objects. This old code causes stack overflows in some (rare) conditions and must be removed. 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: Refactor create_r and flow_req_arr

2019-03-04T07:57:57+00:00

The API calls for the IPCP to inform the IRMd of IPCP creation and incoming flow request had the pid_t in the call. This pid_t is removed and the getpid() call is now placed inside the function. Also refactors the cleanup for the main() functions of some of the lower IPCPs. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add initial rtt estimator to FRCT

2019-02-08T11:39:23+00:00

This adds a simple round-trip time estimator to FRCT. The estimate is a weighted average with deviation. The retransmission is scheduled after rtt + 2 times the deviation. A retransmit doubles the rtt estimate to avoid the no-update case when rtt suddenly increases. The rtt is estimated in microseconds and the granularity for retransmits is 256 microseconds.
