This patch implements 'execve' in Genode's libc.
The mechanism relies on the dynamic linker's ability to replace the
loaded binary while keeping crucial libraries - in particular the libc -
intact. The state outside the libc is wiped. For this reason, all libc
internal state needed beyond the 'execve' call must be allocated on a
heap separate from the application-owned malloc heap. E.g.,
libc-internal file-descriptor objects must not be allocated or refer to
any memory object allocated from the malloc heap.
Issue #3481
This patch extends the fork test with explicit checks for the cloned
content of the heap and RW segment as well as the seek position of an
open file descriptor. It adds the new libports/run/fork.run script
that exercises the fork mechanism implemented by the libc. It is based
on noux_fork.run, which tests the mechansim provided by noux. The
test program has been moved from ports to libports.

To enable the clipboard for a VM, add the following node to the
<Hardware> sub node of your machine.vbox configuration:
<Clipboard mode="Bidirectional"/>
Issue #3437
This patch enhances the noux_vim.run scenario to make it usable as a
testing ground of the terminal's and window manager's resize and
clipboard handling.
Issue #2079
The labels of clipboard ROM and clipboard report sessions of WM clients
must be consistent with the client's nitpicker label. Hence, we must
route those sessions through the window manager, analogously to the
approach taken for shape reports in #3165.
Issue #3437
This is a follow-up commit to the libc update. The FreeBSD
implementation of sigset or sigaction calls the __libc_sigaction now.
The patch fixes the SIGWINCH handling for Vim when interactively
resizing the terminal window.
Fixes#3424
- use priorities solely with nova
- handle exceptions during vCPU creation
- avoid assertion in vga_vbda
- silence compiler warnings about outdated register keyword
Issue #3111
This prevents
error copying "bin/libm.lib.so": no such file or directory
error copying "bin/posix.lib.so": no such file or directory
when running "make run/noux" from an empty build directory.
either
- due to poor signal performance of base platform
- due to being to less prioritized
- due to schedule overload
- due to using time sources of different physical CPUs
