... and set initial time by using RTC session.
Up to now Noux used a monotic clock whose initial start value always
was '0' (which correlates to the start of the UNIX epoch) to provide
a notion of time. In addition it is now possible to use the RTC
session to set the initial value for use cases where having a proper
real-world time matters.
To use the RTC session the 'rtc' attribute of the '<config>' node
must be set to 'yes'. Thereby the session becomes a mandatory
dependency as Noux will not start without it.
Issue #1784
This patch complements the commit "libc: execve" with the ability to
execute files stored at arbitrary sub directories of the file system.
Issue #3481
Issue #3500
This patch removes ldso's builtin policy of removing any path elements
prepending the ROM module name. Instead, the ROM name is used as is.
This clears the way to access different ROM modules that share the same
name but are stored at different directories behind an fs_rom (e.g.,
/bin/bash vs. /usr/local/bin/bash).
Issue #3500
This patch replaces the naive dup2 implementation (that merely
duplicated the context pointer) by the replication of the original
FD state by re-opening the same file with the same flags and seek
position. This prevents a potential double release of the VFS handle
(the FD context). It also implements 'dup'.

Issue #3497
This patch unifies the patterns of using the 'Genode' and 'Libc'
namespaces.
Types defined in the 'internal/' headers reside in the 'Libc'
namespace. The code in the headers does not need to use the
'Libc::' prefix.
Compilation units import the 'Libc' namespace after the definition of
local types. Local types reside in the 'Libc' namespace (and should
eventually move to an 'internal/' header).
Since the 'Libc' namespace imports the 'Genode' namespace, there is
no need to use the 'Genode::' prefix. Consequently, code in the
compilation units rarely need to qualify the 'Genode' or 'Libc'
namespaces.
There are a few cases where the 'Libc', the 'Genode', and the global
(libc) namespaces are ambigious. In these cases, an explicit
clarification is needed:
- 'Genode::Allocator' differs from 'Libc::Allocator'.
- 'Genode::Env' differs from 'Libc::Env'.
- Genode's string functions (strcmp, memcpy, strcpy) conflict
with the names of the (global) libc functions.
- There exist both 'Genode::uint64_t' and the libc'c 'uint64_t'.
Issue #3497
This patch is the first step of re-organizing the internal structure of
the libc. The original version involved many direct calls of global
functions (often with side effects) across compilation units, which
made the control flow (e.g., the initialization sequence) hard to
follow.
The new version replaces those ad-hoc interactions with dedicated
interfaces (like suspend.h, resume.h, select.h, current_time.h). The
underlying facilities are provided by the central Libc::Kernel and
selectively propagated to the various compilation units. The latter is
done by a sequence of 'init_*' calls, which eventually will be replaced
by constructor calls.
The addition of new headers increases the chance for name clashes with
existing (public) headers. To disambiguate libc-internal header files
from public headers, this patch moves the former into a new 'internal/'
subdirectory. This makes the include directives easier to follow and the
libc's source-tree structure more tidy.
There are still a few legacies left, which cannot easily be removed
right now (e.g., because noux relies on them). However, the patch moves
those bad apples to legacy.h and legacy.cc, which highlights the
deprecation of those functions.

- readv_writev: move 'rw_lock' instance into a function scope,
constructing the instance on the first access.
- select: move 'select_cb_list' instance into function scope.
- thread: move 'key_list_lock' and 'keys' into function scope.
- rwlock, semaphore, socket_fs_plugin, thread, thread_create:
instantiate 'Libc::Allocator' per use, alleviating the need for a
global instance.
Issue #3496
Implement getifaddrs and freeifaddrs within the libc using socket
control files at the VFS. Add an "address" and "netmask" file to the
lwIP plugin.
Only a single IPv4 address is initially supported, and the broadcast
address returned will never be valid.
Fixes#3439
The check was accidentally in
66d44289e1 tool/ports: streamline hash tool usage
because $(call VAR, ...) just expands to nothing without errors if VAR
is undefined.
This adds complete character-generator configurations for English (US),
German (Germany and Switzerland), and French (France and Switzerland).
The configs are manually amended and stripped-down versions of
xkb2ifcfg generated configs.
