So far, this test used dynamic_rom for the re-configuration of the nic router and tested for the expected ping results by inspecting the log with the run tool. However, this approach had two issues: * Timing differs significantly on different targets and so the dynamic_rom had the difficult task of compensating with heuristics without bloating the test duration too much. * In case of a failing test, it was difficult to determine the cause as the test kept running and produced output for quite some time and there was also no specific error message but only a generic timeout. These two issues are now fixed by introducing a test component that listens to the ping-result report and manages the nic router configuration. The new component exits early on failure and provides information on the error circumstances. Furthermore, the component advances to the next test step only after having seen the expected result of the active test step and thereby removes the need for heuristics about target timing.

Storage ~~~~~~~ Please consult repos/os/src/driver/usb_block/README for a description. Network (Nic) ~~~~~~~~~~~~~ Please consolut repos/dde_linux/src/driver/usb_net/README for a description. LXIP #### LXIP is a port of the Linux TCP/IP stack to Genode. It is build as a shared library named 'lxip.lib.so'. The IP stack can be interfaced using Genode's version of 'libc' by linking your application to 'lxip_libc' plugin in your 'target.mk' file. Wifi #### The 'wifi' driver consists of a port of the mac802.11 stack, platform-specific drivers and the 'wpa_supplicant' to Genode. lx_kit ###### The modular lx_kit seperates the required back end functionality of the Linux emulation environment from the front end. Thereby each driver can reuse specific parts or supply more suitable implementations by itself. It is used to reduce the amount of redundant code in each driver. The lx_kit is split into several layers whose structure is as follows: The first layer in _repos/dde_linux/src/include/lx_emul_ contains those header files that provide the structural definitions and function declarations of the Linux API, e.g. _errno.h_ provides all error code values. The second layer in _repos/dde_linux/src/include/lx_emul/impl_ contains the implementation of selected functions, e.g. _slab.h_ provides the implementation of 'kmalloc()'. The lx_kit back end API is the third layer and provides the _Lx::Malloc_ interface (_repos/dde_linux/src/include/lx_kit/malloc.h_) which is used to implement 'kmalloc()'. There are several generic implementations of the lx_kit interfaces that can be used by a driver. A driver typically includes a 'lx_emul/impl/xyz.h' header once directly in its lx_emul compilation unit. The lx_kit interface files are only included in those compilation units that use or implement the interface. If a driver wants to use a generic implementation it must add the source file to its source file list. The generic implementations are located in _repos/dde_linux/src/lx_kit/_. The modular lx_kit still depends on the private _lx_emul.h_ header file that is tailored to each driver. Since the lx_kit already contains much of the declarations and definitions that were originally placed in these private header files, those files can now ommit a large amount of code.
