In the past, the Genode::destroy, that is called by the RAM-FS-chunk destructors,
issued Allocator::free instead of the C++ delete. Therefore it was possible to
use the size argument of Allocator::free for the allocation tracker in the
RAM-FS-chunk test. Nowadays, we have to keep track of the allocation sizes
ourselves because delete doesn't hand over the size.

The FB Block Adapter in os/src/test visualizes a block session via a
Framebuffer session. As far as I can see, it is not a test but rather
the base for a bump-in-the-wire component. However, for this role it
currently lacks a Block back-end. As it also would have to be updated to
use the new base API I removed it instead, leaving only its git
history as inspiration if someone needs such a component in the future.

lesskey and lessecho missed the declaration of ${LIBS} on the compiler
command line, which ended up in unusable programs.

noux-pkg/less/lesskey: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter ld.lib.so, not stripped
The issue was identified because -O0 builds broke with
ld: lesskey: The first section in the PT_DYNAMIC segment is not the .dynamic section
Unfortunately, this simple fix renders both tools also dependent to libm
and ncurses which they don't use.
This streamlines the Genode-specific interface for both 32-bit and
64-bit architectures and fixes dynamic-linking issue with the rump
VFS due to differing size_t types.
This function returns the information whether the used platform relies
on USB HID for interactive scenarios by default as is the case for most
ARM platforms. In contrast, for x86 the USB driver can be omitted because
we can use the PS/2 driver (that is readily available in repos/os/).
If the detach address is not the beginning of the region, one gets:
"virtual void Genode::Allocator_avl_base::free(void*): given
address (0x180e0) is not the block start address (0x18000)"
Instead, print an explicit warning in front of the detach call.
Cleaning up LWIP when returning from the main function sporadically
leads to endless errors "Error: sys_arch_mbox_fetch: unknown exception
occured!". We let the client sleep forever at the end of its main function
to prevent tests from failing due to a flooded log.
Reg #2193
* get rid of printf
* use exceptions instead of error codes
* use Id_space instead of the individual block device registry
* use Cstring instead of char const*
* move method definitions > 1 line to .cc files
* rename Block Block_driver and Serial Serial_driver to avoid name clashes
with the Genode namespace and thereby simplify the code
* use lambdas for Block device lookup and apply
* switch to the Component framework
* don't use env(), config(), ... and hand over env to each connection
* use Attached_mmio and Attached_rom/ram_dataspace instead of manual
solutions
Fixes#2223
The init component used to create the CPU/RAM/PD/ROM sessions (the child
environment) for its children by issuing session requests to its parent,
which is typically core. This policy was hard-wired. This patch enables
the routing of the environment sessions of the children of init
according to the configured routing policy.
Because there is no hard-wired policy regarding the environment sessions
anymore, routes to respective services must be explicitly declared in
the init configuration. For this reason, the patch adjusts several run
scripts in this respect.
This patch removes the outdated '<if-args>' special handling of session
labels. The '<if-args>' feature will eventually be removed completely

This patch changes the 'Xml_node_label_score' to regard an empty
label_prefix or label_suffix as a match instead of a conflict. Until
now, there was no use case for an empty label_prefix. But with init's
new ability to route environment sessions, an empty prefix denotes any
child-initiated session (as oposed to an parent-initiated environment
session).

This patch fixes a problem that unsurfaced by the commit "menu_view: API
transition", which changed the class layout of the 'Png_image' so that
the 'Read_struct' pointer is no longer equal to the 'Png_image' pointer.
This commit addresses the situation where an environment session
outlives the session-providing service. In this case, the env session
got already invaidated at the destruction time of the server. However,
the underlying session-state structure continues to exist until the
client is destructed. During the eventual destruction of such a dangling
environment session, we have to be careful not to interact with the
no-longer existing service.
Ref #2197
This patch addresses the corner case of destructing a child that
provides an enviroment session to another child. Before this patch,
this situation could result in an infinite loop.
The problem was introduced as a side effect of issue #2197 "base: apply
routing policy to environment sessions".
This patch re-enables the launchpad to start multiple instances of the
same program. Without it, launchpad wrongly requests the binary ROM with
the child's unique name as label. The lookup of the first instance
solely succeeds because the unique name equals the binary name.
To better support non-blocking terminal components, let the
'Terminal::Session::write()' function return the number of bytes
actually written.
