The socket file system can be configured in the "socket" attribute of
the libc config node like follows.
<vfs> <dir name="socket"> <fs/> </dir> </vfs>
<libc ... socket="/socket"/>
This configures the socket file system libc backend to access files in
"/socket" for socket operations.
There existed a race when 'wait_and_dispatch_one_signal' is called form
a RPC context, because the 'signal_proxy' or 'main' will block and the
signal semaphore, when the EP then calls 'wait_and_dispatch_one_signal',
the signal proxy is woken up ands sends an RPC to the EP, leading to a
dead lock if no further signal arrive, because the EP will then remain
blocked in the signal semaphore.
Therefore, for this case, the signal proxy will now perform a semaphore
up operation and does not perform an RPC if the EP is within
'wait_and_dispatch_one_signal'.
This patch enhances init with the ability to route individual
environment sessions. Prior this patch, environment sessions could be
routed only by an all-encompassing '<service>' node that would match
both child-initiated and environment sessions.
In contrast to the existing 'label', 'label_prefix', and 'label_suffix'
attributes of '<service>' nodes, which are always scoped with ther name
of the corresponding child, the 'unscoped_label' allows the definition
of routing rules for all session requests, including init's requests for
the child's environment sessions. For example, to route the ROM session
requests for a child's dynamic linker, the following route would match:
<route>
<service name="ROM" unscoped_label="ld.lib.so"> ... </service>
</route>
Issue #2215
When a directory gets destructed it dissolves the handles of each contained file
but the acknowledgement might be still in-flight. If we finally receive it,
it leads to an Unknown_id exception on the Handles ID Space in 'handle_ack'.
Now we catch it, print a warning, and go on.
This patch adds the handling of 'CHARACTER' events as emitted by the
input-filter's character generator (<chargen>). To avoid interpreting
press/release events twice (at the input filter and by the terminal's
built-in scancode tracker), the terminal's scancode tracker can be
explicitly disabled via <config> <keyboard layout="none"/> </config>.
In the future, the terminal's built-in scancode tracker will be
removed.
The use of the terminal with the input filter is illustrated by the
'terminal_echo.run' script.
Issue #2264
The input_filter is the successor of the input_merger. In addition to
merging input streams, the component applies several forms of input
transformations such as the application of keyboard layouts.
Issue #2264
Character events are created via a dedicated 'Event' constructor that
takes an 'Event:Utf8' object as argument. Internally, the character is
kept in the '_code' member. The 'Utf8' value can by retrieved by the
recipient via the new 'utf8' method.

A binary file may be a temporary Vim .swp file when examining contrib

A Signal_handler may schedule a hook function that is executed after the
signal handler returned. This can be used if the hook function may
trigger a (nested) signal handler by means of
wait_and_dispatch_one_signal(). Otherwise, an occurrence of the same
signal that triggered the original signal handler results in a dead lock
just before calling the nested handler (due to the Signal_context
destruction lock).
The read-ready packet informs the server that the client wants to be
notified if a handle becomes readable. When becoming readable, the
server acknowledges packet and the client may queue a read requests
accordingly.
The i.MX53 Framebuffer driver doesn't come up on on Fiasco.OC because the Platform
driver isn't allowed to access essential devises like the SRC or the Fuses. This is
most likely due to the kernel not configuring the CSU appropriately.

Issue #1987
For now provide a initial memory buffer for allocation of static
constructors and of malloc calls out of the libc during early
libc initialization until actual vbox code is executed having the Env
pointer.
This change introduces a Genode specific init function, which sets the
backend allocator used by jent_zalloc/zfree(). As consequence the
library can solely be used by native Genode components, direct libc
usage is not supported.
Fixes#2274.
Put the initialization of the cpu cores, setup of page-tables, enabling of
MMU and caches into a separate component that is only used to bootstrap
the kernel resp. core.
