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: Don't reuse fqueue between threads

2019-03-21T08:45:54+00:00

The UDP IPCP was reusing fqueues between threads. This is not supported and lead to bad reads and buffer overflows. 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

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
