This is important to issue sync requests for written-to files. As the closing must be performed by an atexit handler, it happens at a time _after_ libc plugins are destructed. Consequently an FD allocated by such a plugin results in a close error, which in turn, does not destruct the FD. We ultimatedly end up in an infinte loop of re-attempting the close. For this reason, the patch changes 'close' to be robust against this special case. This is generally not a problem because libc plugins are phased out. However, at present, the libc_noux plugin is still important. With the changed 'close' in place, there occurred an error message "Error: close: close not implemented" at the exit of each noux program. This patch removes the error printing from the libc plugin mechansim to avoid this noise. The error messages are not important anyway because the deprecation of the libc plugin interface. Issue #3578

Genode source-code repositories
===============================
This directory contains the source-code repositories of the Genode OS
Framework. Each sub directory has the same principle layout as described in the
build-system manual:
:Build-system manual:
[https://genode.org/documentation/developer-resources/build_system]
The build system uses a configurable selection of those reposities to obtain
the source codes for the build process. The repositories are not independent
but build upon of each other:
:'base':
This directory contains the source-code repository of the fundamental
frameworks and interfaces of Genode. Furthermore, it contains the generic
parts of core.
:'base-<platform>':
These directories contain platform-specific source-code repositories
complementing the 'base' repository. The following platforms are supported:
:'linux':
Linux kernel (both x86_32 and x86_64)
:'nova':
NOVA hypervisor developed at University of Technology Dresden
See [https://genode.org/documentation/platforms/nova]
:'foc':
Fiasco.OC is a modernized version of the Fiasco microkernel with a
completely revised kernel interface fostering capability-based
security. It is not compatible with L4/Fiasco.
See [https://genode.org/documentation/platforms/foc]
:'hw':
The hw platform allows the execution of Genode on bare ARM and x86 hardware
without the need for a separate kernel. The kernel functionality is
included in core except in the special case of the Muen separation
kernel.
See [https://genode.org/documentation/platforms/hw] and
[https://genode.org/documentation/platforms/muen]
:'okl4':
OKL4 kernel (x86_32 and ARM) developed at Open-Kernel-Labs.
See [https://genode.org/documentation/platforms/okl4]
:'pistachio':
L4ka::Pistachio kernel developed at University of Karlsruhe.
See [https://genode.org/documentation/platforms/pistachio]
:'fiasco':
L4/Fiasco kernel developed at University of Technology Dresden.
See [https://genode.org/documentation/platforms/fiasco]
:'sel4':
seL4 microkernel developed at NICTA/General Dynamics
See[https://sel4.systems/]
:'os':
This directory contains the non-base OS components such as the init process,
device drivers, and basic system services.
:'demo':
This directory contains the source-code repository of various services and
applications that we use for demonstration purposes. For example, a graphical
application launcher called Launchpad and the Scout tutorial browser.
:'hello_tutorial':
Tutorial for creating a simple client-server scenario with Genode. This
repository includes documentation and the complete source code.
:'libports':
This source-code repository contains ports of popular open-source libraries
to Genode, most importantly the C library. The repository contains no
upstream source code but means to download the code and adapt it to Genode.
For instructions about how to use this mechanism, please consult the README
file at the top level of the repository. Among the 3rd-party libraries
are Qt5, libSDL, freetype, Python, ncurses, Mesa, and libav.
:'dde_linux':
This source-code repository contains the device driver environment for
executing Linux device drivers natively on Genode. Currently, this
repository hosts the USB stack.
:'dde_ipxe':
This source-code repository contains the device-driver environment for
executing drivers of the iPXE project.
:'dde_bsd':
This source-code repository contains the device-driver environment for
drivers of the OpenBSD operating system.
:'dde_rump':
This source-code repository contains the port of rump kernels, which are
used to execute subsystems of the NetBSD kernel as user level processes.
The repository contains a server that uses a rump kernel to provide
various NetBSD file systems to Genode.
:'dde_zircon':
This repository contains the emulation environment for drivers
ported from the Zircon kernel.
:'ports':
This source-code repository hosts ports of 3rd-party applications to
Genode. The repository does not contain upstream source code but provides
a mechanism for downloading the official source distributions and adapt
them to the Genode environment. The used mechanism is roughly the same
as used for the 'libports' repository. Please consult 'libports/README'
for further information.
:'gems':
This source-code repository contains Genode applications that use
both native Genode interfaces as well as features of other high-level
repositories, in particular shared libraries provided by 'libports'.
