b35df4578b Check Registered base class provides virtual destructor
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.

cb43e04691 ldso: defer execution of static constructors
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.

8d68d3d8ac Adapt resource-request test to changes of init
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".

1fde4d638c init: service forwarding
This patch equips init with the ability to act as a server that forwards
session requests to its children. Session requests can be routed
depending of the requested service type and the session label
originating from init's parent.

The feature is configured by one or multiple <service> nodes hosted in
init's <config> node. The routing policy is selected by via the regular
server-side policy-selection mechanism, for example:

<config>
  ...
  <service name="LOG">
    <policy label="noux">
      <child name="terminal_log" label="important"/>
    </policy>
    <default-policy> <child name="nitlog"/> </default-policy>
  </service>
  ...
</config>

Each policy node must have a <child> sub node, which denotes name of the
server with the 'name' attribute. The optional 'label' attribute defines
the session label presented to the server, analogous to how the
rewriting of session labels works in session routes. If not specified,
the client-provided label is presented to the server as is.

1489791d5e init: explicit response to resource requests
This patch removes the formerly built-in policy of responding to
resource requests with handing out slack quota. Instead, resource
requests have to be answered by an update of the init configuration with
adjusted quota values.

Note that this patch may break run scripts that depend on init's
original policy. Those run scripts may be adjusted by increasing the
quota for the components that use to inflate their RAM usage during
runtime such that the specified quota suffices for the entire lifetime
of the component.

06943f413d init: respond to RAM-quota changes in config
This patch improves init's dynamic reconfigurability with respect to
adjustments of the RAM quota assigned to the children.

If the RAM quota is decreased, init withdraws as much quota from the
child's RAM session as possible. If the child's RAM session does not
have enough available quota, a resource-yield request is issued to
the child. Cooparative children may respond to such a request by
releasing memory.

If the RAM quota is increased, the child's RAM session is upgraded.
If the configuration exceeds init's available RAM, init re-attempts
the upgrade whenever new slack memory becomes available (e.g., by
disappearing other children).

b3e5357cf1 Adaptation to init refactoring
Since init no longer provides public headers, we have to adjust the
existing users of this headers. The 'init/child_config.h' is used only
by GDB monitor. So the patch moves the header there as an interim fix.
The 'init/child_policy.h' is still used by a few components, so we have
to keep a trimmed-down version of it for now.

9dca1503a8 init: apply changes of <provides> nodes
This patch enables init to apply changes of any server's <provides>
declarations in a differential way. Servers can in principle be extended
by new services without re-starting them. Of course, changes of the
<provides> declarations may affect clients or would-be clients as this
information is taken into account for the session routing.

fcf25c22d1 init: respond to binary-name changes
This patch covers the resolution of the ROM route for child binaries
via the generic label-rewriting mechanics. Now, the <binary> node has
become merely sytactic sugar for a route like the following:

<start name="test"/>
  <route>
    <service name="ROM" unscoped_label="test">
      <parent label="test-binary-name"/> </service>
      ...
  </route>
  ...
</start>

A change of the binary name has an effect on the child's ROM route to
the binary and thereby implicitly triggers a child restart due to the
existing re-validation of the routing.

48174ab974 base: pass separate label to Local_connection
This patch extends the constructor of 'Local_connection' with an
optional 'label' argument, which was previously passed implicitly as
part of the 'args' argument. Keeping the label separate from 'args'
enables us to distinguish the client-specified label from a label that
resulted from a server-side label as it is used when rewriting a label
of an environment session (i.e., the binary name) in init's routing
policy. In principle, this patch eliminates the need for init's
explicite handling of the binary name via the '<binary>' node, or
at least allows us to simplity the binary-node handling.

3ac3236a28 Noux: 'empty' ROM service for initial ROMs
The initial ROMs (program and linker) are already attached to the region
map of a forked process and don't need to be obtained again from an
external ROM service when the 'Child' class asks for them. For the program
image, the local Noux ROM service already returned an invalid dataspace
capability, but not for the linker.

Instead of adding another 'magic' ROM name for the local ROM service,
this commit implements an 'empty' ROM service, which returns an
invalid dataspace for the initial ROMs.

bf96c7f16e platform/x86: fix quota for local ram session
Transfer quota to the session local RAM session to react to the
Quota_exceeded exception properly.

The platform driver keeps a session local RAM session for each of its
clients that is used to allocate DMA memory. A client needs to transfer
some of its quota to the platform driver, which in return transfers this
quota to the session local RAM session. As it happens allocating memory
from a RAM session involves book keeping and in this case, where the
available quota in the session did not suffice and the request was only
a few KiB, the platform driver handled the exception wrongly and did not
transfer the quota.

This problem did not surface up to now because all drivers allocate DMA
memory in larger chunks and the book keeping overhead was of no
consequence as the initial quota transfer probably covered the overhead.

b05b5616c8 x86 cpu_quota: lower error tolerance
Previously, on X86, the timer driver used the PIT with a maximum timeout
of 54 ms.  Thus, the driver frequently interrupted the counters with
highest priority to update the timer. This is why we needed a higher
error tolerance as for ARM where the driver, once configured, can sleep
for the whole test timeout. Now, we use the kernel timer and the problem
seems to be exits no longer.

574a1bd198 test/cpu_quota: tolerate errors in session quota
Previously we pre-calculated the translation errors for the session
quota to make a discret check in the test. But since the order, in which
init childs get their CPU quota isn't always the same anymore (we should
have never made assumptions about that) the translation errors differ
from trial to trial. However, the errors are below 0.01% of the super
period. We now tolerate them in the run script.

56cafb3b57 hw: fix race in signal dispatching
There was a race when the component entrypoint wanted to do
'wait_and_dispatch_one_signal'. In this function it raises a flag for
the signal proxy thread to notice that the entrypoint also wants to
block for signals. When the flag is set and the signal proxy wakes up
with a new signal, it tried to cancel the blocking of the entrypoint.
However, if the entrypoint had not reached the signal blocking at this
point, the cancel blocking failed without a solution. Now, the new
Kernel::cancel_next_signal_blocking call solves the problem by storing a
request to cancel the next signal blocking of a thread immediately
without blocking itself.

This patch improves the accuracy of init's quota-saturation feature
(handing out all slack quota to a child by specifying an overly high RAM

The preservation is specified as follows:

! <config>
!   ...
!   <resource name="RAM" preserve="1M"/>
!   ...
! </config>

If not specified, init has a reasonable default of 160K (on 32 bit) and

7d9f68493a base: support for multi-staged child startup
This patch enhances the 'Child' and 'Child_policy' with the ability to
separate the different steps of bootstrapping children. If the
'Child_policy::initiate_env_sessions()' returns false, the child's
environment sessions remain unrouted at construction time. This way,
child objects for many children can be initialized to a state that
allows the children to represent services for other children. Therefore,
session routing can be applied before any child executes.

At this stage, the environment RAM sessions of all children can be
created. Note that this step still has the limitation that RAM sessions
are generally expected to be provided by either the parent or a local
service.

Once all children are equipped with RAM, they can in principle receive
session-quota donations. Hence, all other environment sessions can now
be arbitrarily routed and initiated.

Once the environment of a child is complete, the child's process and
initial thread is created.

allocated by a child-local heap partition fed from the child's RAM
session. However, whereas this approach was somehow practical from a
runtime's (parent's) point of view, the child component could not count
on the quota in its own RAM session. I.e., if the Child::heap grew at
the parent side, the child's RAM session would magically diminish. This
caused two problems. First, it violates assumptions of components like
init that carefully manage their RAM resources (and giving most of them
away their children). Second, if a child transfers most of its RAM
session quota to another RAM session (like init does), the child's RAM
session may actually not allow the parent's heap to grow, which is a
very difficult error condition to deal with.

In the new version, there is no Child::heap anymore. Instead, session
states are allocated from the runtime's RAM session. In order to let
children pay for these costs, the parent withdraws the local session
costs from the session quota donated from the child when the child
initiates a new session. Hence, in principle, all components on the
route of the session request take a small bite from the session quota to
pay for their local book keeping

Consequently, the session quota that ends up at the server may become
depleted more or less, depending on the route. In the case where the
remaining quota is insufficient for the server, the server responds with
'QUOTA_EXCEEDED'. Since this behavior must generally be expected, this
patch equips the client-side 'Env::session' implementation with the
ability to re-issue session requests with successively growing quota
donations.

For several of core's services (ROM, IO_MEM, IRQ), the default session
quota has now increased by 2 KiB, which should suffice for session
requests to up to 3 hops as is the common case for most run scripts. For
longer routes, the retry mechanism as described above comes into effect.
For the time being, we give a warning whenever the server-side quota
check triggers the retry mechanism. The warning may eventually be
removed at a later stage.

84fddafda7 init: enable init to report its internal state
This patch equips init with the ability to report its internal state in
the form of a "state" report. This feature can be enabled by placing a
'<report>' node in init's configuration.

The report node accepts the following arguments (with their default
values):

'delay_ms="100"': specifies the number of milliseconds to wait before
  producing a new report. This way, many consecutive state changes -
  like they occur during the startup - do not result in an overly
  large number of reports but are merged into one final report.

'buffer="4K"': the maximum size of the report in bytes. The attribute
  accepts the use of K/M/G as units.

'init_ram="no"': if enabled, the report will contain a '<ram>' node
  with the memory stats of init.

'ids="no"': supplement the children in the report with unique IDs, which
  may be used to infer the lifetime of children accross configuration
  updates in the future;

'requested="no"': if enabled, the report will contain information about
  all session requests initiated by the children.

'provided="no"': if enabled, the report will contain information about
  all sessions provided by all servers.

'session_args="no"': level of detail of the session information
  generated via 'requested' or 'provided'.

'child_ram="no"': if enabled, the report will contain a '<ram>' node
  for each child based on the information obtained from the child's RAM
  session.

9d683a56a0 base: add Child_policy::session_state_changed()
This method is a hook to enable a runtime to respond to state changes.
In particular, in init this hook is used to trigger the generation of a
new state report, if configured.

Furthermore, the patch introduces the 'generate_client_side_info' and
'generate_server_side_info' methods to the 'Session_state', which
generates an XML representation of the session states to appear in
reports produced by init.

412c5e5be4 run/platform_drv: add append-free interface
Normally, the platform driver helpers adapt the global run variables directly
via append. But the introduction of a more elegant run script style, that
incorporates dependent strings inline may be a good idea. Thus, we need the
backends of the helpers available as functions that return their string rather
than appending it.

The old interface still exists and uses the new interface as backend.

8cb0dc9c16 init: session-label rewriting
This patch enhances init with the support for rewriting session labels
in the target node of a matching session route. For example, a Noux
instance may have the following session route for the "home" file
system:

<route>
  <service name="File_system" label="home">
    <child name="rump_fs"/>
  </service>
  ...
</route>

At the rump_fs file-system server, the label of the file-system session
will appear as "noux -> home". This information may be evaluated by
rump_fs's server-side policy. However, when renaming the noux instance,
we'd need to update this server-side policy.

With the new mechanism, the client's identity can be hidden from the
server. The label could instead represent the role of the client, or a
name of a physical resource. For example, the Noux route could be
changed to this:

<route>
  <service name="File_system" label="home">
    <child name="rump_fs" label="primary_user"/>
  </service>
  ...
</route>

When the rump_fs receives the session request, it is presented with the
label "primary_user". The fact that the client is "noux" is not taken
into account for the server-side policy selection.

c0af463b81 base: Add Child_policy::Route
The new return value of 'resolve_session_request' allows the child

Because this patch introduces the distinction of the child-provided

request, the latter is now handled as a dedicated 'Session_state'
argument.

eab477370f libc: select support for components
Libc components cannot use regular calls to select() as this may suspend
their execution. In this case incoming RPCs will be deferred until
select() returns and the component returns to the entrypoint dispatch
loop. The Libc::Signal_handler solves this problem with a its select()
that either returns the currently ready file descriptors immediately or
calls the registered handler function during libc resume.

b66716d278 base: entrypoint 'wait_and_dispatch_one_signal'
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'.

652f92c9c9 init: 'unscoped_label' session-routing attribute
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>

c0d61858c3 Support for suspendable read in VFS and libC
The support has two parts. First, a VFS plugin now gets passed an
I/O-response handler callback on construction, which informs users of the
VFS that an I/O event occurred. This enables, for example, the libC to
check if blocking read can be completed. Further, the VFS file I/O
interface provides now functions for suspendable reads, i.e.,
queue_read() and complete_read().

On Odroid XU the SD card driver comes up and finds a card but for card

On imx_53, the first SDHCI MMIO access faults. This is likely due to the

when I tried doing that in the platform driver instead, the first AIPSTZ
MMIO access faults ^^ So I gave up for now and removed support.

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

ourselves because delete doesn't hand over the size.

02d5efcf3f init: apply routing to environment sessions
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
(ref #2250)
