Init's service forwarding functionality did not take the service type
into account when forwarding a session request. If a server provides
multiple services, e.g. fb_sdl that provides both "Input" and
"Framebuffer", the type of the forwarded session request did not always
correspond to the actually requested type.
The size of the whole table and table entries were exchanged for PML4,
leading to out-of-bound accesses for addesses >= 2^39. Some constants
were lacking type suffixes causing integer overflows.
Added assertions to catch out-of-bound accesses early on.

If we do the tics-to-us translation with one division and multiplication
over the whole argument, like before, we loose microseconds granularity
although the timer frequency allows for such granularity. Thus, we treat
the most significant half and the least significant half of the tics
value separate. Each half is shifted to the best bit position for the
translation, then translated, and then shifted back.
Ref #2347
The use of 'select_from_repositories' for locating the linker script for
dynamically-linked executables only works if 'BASE_DIR' appears in the
list of 'REPOSITORIES'. This is the case when using the build system in
the traditional way but it is not desired when building binary archives
of individual components.
This patch adjusts the run script in two ways:
It removes the reliance on init's formerly built-in resource-request
handling by increasing the RAM quota for the backdrop instances. Since
commit "init: explicit response to resource requests", init no longer
hands out slack memory automatically.
Second, it makes sure that the backdrop appears under the precise label
"backdrop" at nitpicker by facilitating init's label-rewriting feature.
Without explicitly setting the label to "backdrop", nitpicker observes
the label "backdrop -> backdrop" (the first part comes from init, the
second part comes from the nitpicker-session argument specified by
backdrop itself). However, the client is only considered as default
background if labeled as "backdrop" (see nitpicker's '_create_session')
implementation.
Issue #2352
The base class of Registered must provide a virtual destructor to enable
safe deletion with just a base class pointer. This requirement can be
lifted by using Registered_no_delete in places where the deletion
property is not needed.
Fixes#2331
Ldso now does not automatically execute static constructors of the
binary and shared libraries the binary depends on. If static
construction is required (e.g., if a shared library with constructor is
used or a compilation unit contains global statics) the component needs
to execute the constructors explicitly in Component::construct() via
Genode::Env::exec_static_constructors().
In the case of libc components this is done by the libc startup code
(i.e., the Component::construct() implementation in the libc).
The loading of shared objects at runtime is not affected by this change
and constructors of those objects are executed immediately.
Fixes#2332
With the current implementation resource requests are not automically
satisfied with slack quota by init. Therefore, this commit adapts RAM
quotas of autopilot scenarios to the actual demands.
An inline attribute mismatch in the gcc-4.9.2 source causes its
compilation to fail on modern gcc versions (verified with gcc 6.3.1,
but probably since gcc 5)

The test used to rely on init's formerly built-in policy of answering
resource requests with slack memory, if available. Since init no longer
responds to resource requests in an autonomous way, we use a dynamically
configured sub-init instance as runtime for the test. This instance, in
turn, is monitored and controlled such that resource requests are
result in quota upgrades. The monitoring component is implemented in
the same test-resource_request program as the test. Both roles are
distinguished by the "role" config attribute.
This is a follow-up to "init: explicit response to resource requests".
- use more upstream hm code
- add call to memory check as done in vbox4
- add in principle all vbox devices and drivers
- avoid null pointer during VM startup (patch reported to vbox-devel list)
- avoid endless loop in usb root hub
