af146e7dcd Remove base/timed_semaphore.h from API
The former 'Genode::Timed_semaphore' mechanism is moved to the private
part of the two remaining users, namely dde_rump and the libc. Note
there are now two private copies of 'timed_semaphore.h'. This should be
regarded as an interim step until the use of this mechanism is removed
from both users.

This patch also cleans up the mechanism from legacy Genode API calls and
global side effects (alarm-thread singleton). The test/timed_semaphore
is now located at the libports repository as it now tests a mechanism of
the libc. The former timed_semaphore library is no more.

bf62d6b896 Move timer from os to base repository
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.

Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.

Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.

cc4a72243d print_lines: fix bugs in line length calculation
1) The loop for determining the line length read from a character offset
   before checking whether the offset is smaller than the given string

2) The routine for determining the line length first seeked for the
   offset of the last real character of the line and than added one for
   getting the length but only if the following character was '\n'. This
   has to be done for any other line-terminating character too. The only
   case where you don't want to do this is when the end of the whole
   string is reached.

4b46abf813 base: rm first-class support for static binaries
This patch removes the detection of statically linked executables from
the base framework. It thereby fixes the corner cases encountered with
Sculpt when obtaining the binaries of the runtime from the depot_rom
service that is hosted within the runtime.

Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries
can still be started by relabeling the ROM-session route of "ld.lib.so"
to the binary name, pretending that the binary is the dynamic linker.
This can be achieved via init's label rewriting mechanism:

  <route>
    <service name="ROM" unscoped_label="ld.lib.so">
      <parent label="test-platform"/> </service>
  </route>

However, as this is quite cryptic and would need to be applied for all
lx_hybrid components, the patch adds a shortcut to init's configuration.
One can simply add the 'ld="no"' attribute to the <start> node of the
corresponding component:

  <start name="test-platform" ld="no"/>

fbe9d26c47 trace: initialize trace control in Thread::start
Previously, the trace control of a thread was initialized in its
constructor (which is generic for all components). This has the
disadvantage that the CPU-session-pointer member of the thread might not
be valid at this point. And it cannot be replaced by using the
"deprecated_env" CPU session neither as constructing the deprecated
environment in causes troubles in Core. But as the trace control
shouldn't be needed in Core anyway, the initialization can be moved to
the Thread::start implementation of non-core components. This code
already takes care of the CPU session pointer.

39e6dd3d25 core: destruction order of PD session members
This patch addresses a corner case revealed by the resource_request test
on seL4 after changing the child-destruction handling with commit "base:
close PD on 'close_all_sessions'". During the destruction of the PD
session, the backing store (session-local RAM dataspace factory) of the
signal broker's slab was destroyed before destructing the signal broker.
Instantiating the signal broker after the RAM dataspace factory fixes
the destruction order.

a3858bff3c base: handle cancelation of session creation
This patch improves the handling of the corner case where a client
vanishes while a session request is in flight (CREATE_REQUESTED but
not yet AVAILABLE). This corner case could be sporadically observed with
the init_loop test on base-linux.

In the original version, the session would eventually be delivered but
never picked up by anyone. Such a stale session still uses resources that
should better be released. In the new version, the parent checks for the
liveliness of the client whenever a session is delivered. If there is no
client of the session, a close request is immediately issued to the
server. The session state must be preserved until the close requests has
been answered.

ddff89d43e base: close PD on 'close_all_sessions'
This patch moves the closing of a child's PD session from the 'Child'
destructor to the 'close_all_sessions' method. This way, the child's
PD quota is immediately returned as soon as init flags a child as
'abandoned', which removes jitter from init's RAM-state reports.

The patch is supposed to make the 'init_loop.run' test much happier.

This patch ensures that session-create requests are handled after close

expanding a partition with Sculpt, the gpt-write tool is removed and
part_blk is started (to execute resize2fs on top) in one step. Both
interact with the USB-block driver, which is a single-session server.

fc90c5f8f0 session_label: make typedef String public
Internally, Genode::Session_label has a typedef from String<capacity()> to
String. To have this typedef public is especially useful when reading a
label from an XML node. This can then be written as

! Session_label label = node.attribute_value("label", Session_label::String());

instead of

! Session_label label = node.attribute_value("label", String<160>());

which would be less generic (Session_label cannot be used directly as there
is no appropriate ascii_to implementation).

81613afa03 base: fix quota transfer to async env services
Whenever an environment session was provided by an asynchronous service,
e.g., the depot_rom of the sculpt scenario, the session quota was not
transferred to the server at session-creation time. This resulted in a
slow depletion of the server's quota over time. This patch ensures that
the delivery of session quota is consistent with the information
reported to the server as session argument.

578bec11ac base: fix quota reversing when clients vanish
The 'Child::_revert_quota_and_destroy' assumes to be called from the
client's context, which is normally the case when destroying sessions.
However, if a client's session outlives the client (because the
asynchronous close request to the server is still pending), the session
cleanup is performed in the context of the server. Here, the
'session_response' implementation wrongly called
'_revert_quota_and_destroy' to the effect that the session quota was
withdrawn from the server (good) but subsequently transferred back to
the server (bad). The patch replaces the call of
'_revert_quota_and_destroy' with only the first - correct - part of the
transaction.

7b6b3a4535 base: fix destruction of async env sessions
When an environment session is provided by a async service such as a
sibling component, the session metadata must be preserved until end of
the lifetime of the session at the server has been acknowledged by the
server. Since the session meta data of env sessions are always part of
the 'Child' object, the destruction of this object must be deferred
until this point.

9fc3344ee8 trace/buffer: keep "last" entry on wraps
When the former trace buffer implementation wrapped, the last entry
according to commit order couldn't be detected anymore. Now, the last
committed entry is always followed by an entry with length 0.

As a downside of this, there are now two meanings of "last" entry: It
means either that the entry marks the empty padding after the entry with
the highest memory address or that it actually marks the end of the
buffer according to commit order. This is an example state of the buffer
with the two types of "last" entry:

                           last                                     last
+-------------+------------+---+---------+-------------+------------+---+-------+
| len3  data3 | len4 data4 | 0 | empty   | len1  data1 | len2 data2 | 0 | empty |
+-------------+------------+---+---------+-------------+------------+---+-------+

If the entry with the highest memory address fits perfectly, the first
type of "last" entry is not needed:

                                  last
+------------+--------------------+---+-------+-------------+-------------------+
| len3 data3 | len4         data4 | 0 | empty | len1  data1 | len2        data2 |
+------------+--------------------+---+-------+-------------+-------------------+

If the buffer didn't wrap so far, there is only one "last" entry that
has both meanings:

                                                      last
+--------------------------+------------+-------------+---+---------------------+
| len1               data1 | len2 data2 | len3  data3 | 0 | empty               |

1261c18ce9 ada: runtime and library support
The Ada runtime can now be set with the ADA_RTS variable. The ada
library builds a (currently) minimal runtime from the gcc sources that
come with Genode (to stay consistent with the used compiler) and sets
the runtime path accordingly. It is build as a shared library ada.lib.so
which needs to be added to the build files.

I split the existing Ada test into program and library, and moved it
to libports as it depends on the runtime library residing in this
repository too.

47724c68c2 platform_drv/x86: Switch to ECAM/MMCONF
Switch port I/O based PCI config space access to memory-mapped IO.  The
base address of the PCI configuration space is acquired by mapping the
ACPI ROM and reading the first <bdf> node. An exception is thrown if the
first <bdf> node is not for PCI domain zero or if multiple <bdf> nodes
exist. This is to reduce complexity and also because multiple PCI
domains are rare.

The PCI configuration space is accessed via I/O mem dataspace which is
created in the platform_drv root and then passed on to the PCI session,
device components and finally to the actual PCI config access instances.

The memory access code is implemented in a way to make it work with Muen
subject monitor (SM) device emulation and also general x86 targets. On
Muen, the simplified device emulation code (which works also for Linux)
always returns 0xffff in EAX to indicate a non-existing device.
Therefore, EAX is enforced in the assembly templates.

abf9557bb5 AVL node/tree: make non-copyable
AVL trees can't be copied with the default copy constructor as the
parent pointer of the first item of both of the resulting trees would
point to the original tree. Copying an AVL node, however, generally
violates the integrity of the corresponding tree. The copy constructor
of Avl_tree is used in some places but in those places it can be
replaced easily. So, this commit deletes the copy constructor of
Avl_node_base which makes Avl_node and Avl_tree non-copyable.

e0e9b3b32e init: close all sessions of exited children
With this patch, init responds to the exit of a child by closing all
sessions of the child. E.g., if a child is a GUI application, its
nitpicker session is closed at the time of exit, not at the time when
the start node disappears from init's configuration.

Since this change requires a modification of the 'Genode::Child' class,
it takes the chance to make the child-destruction less brutal. The
new version ensures that all threads of the destructed subsystem are
destructed before other sessions, in particular PD sessions. This
eliminates spurious page-fault warnings during the child destruction.

On Fiasco.OC, closing the CPU session of a thread while being called by
the thread causes a deadlock. Hence, we skip the eager destruction of
CPU sessions on this kernel.

level is not applicable, the variable may be explictly set to an empty
value in the corresponding build-description file.

eba9c15746 Follow practices suggested by "Effective C++"
The patch adjust the code of the base, base-<kernel>, and os repository.
To adapt existing components to fix violations of the best practices
suggested by "Effective C++" as reported by the -Weffc++ compiler
argument. The changes follow the patterns outlined below:

* A class with virtual functions can no longer publicly inherit base
  classed without a vtable. The inherited object may either be moved
  to a member variable, or inherited privately. The latter would be
  used for classes that inherit 'List::Element' or 'Avl_node'. In order
  to enable the 'List' and 'Avl_tree' to access the meta data, the
  'List' must become a friend.

* Instead of adding a virtual destructor to abstract base classes,
  we inherit the new 'Interface' class, which contains a virtual
  destructor. This way, single-line abstract base classes can stay
  as compact as they are now. The 'Interface' utility resides in
  base/include/util/interface.h.

* With the new warnings enabled, all member variables must be explicitly
  initialized. Basic types may be initialized with '='. All other types
  are initialized with braces '{ ... }' or as class initializers. If
  basic types and non-basic types appear in a row, it is nice to only
  use the brace syntax (also for basic types) and align the braces.

* If a class contains pointers as members, it must now also provide a
  copy constructor and assignment operator. In the most cases, one
  would make them private, effectively disallowing the objects to be
  copied. Unfortunately, this warning cannot be fixed be inheriting
  our existing 'Noncopyable' class (the compiler fails to detect that
  the inheriting class cannot be copied and still gives the error).
  For now, we have to manually add declarations for both the copy
  constructor and assignment operator as private class members. Those
  declarations should be prepended with a comment like this:

        /*
         * Noncopyable
         */
        Thread(Thread const &);
        Thread &operator = (Thread const &);

  In the future, we should revisit these places and try to replace
  the pointers with references. In the presence of at least one
  reference member, the compiler would no longer implicitly generate
  a copy constructor. So we could remove the manual declaration.

fb2398dbf2 run: target-specific config schemata
The run tool now by default checks configurations with target-specific
XML schemata. Each component may define a config schema file in its
target.mk via the CONFIG_XSD variable. When the run tool has checked an
configuration of an init instance, it additionally goes through the
start nodes of the config. For each start node it checks whether there
is an XSD file that matches. If so, the run tool also checks the config
of the start node (if existant). This is done recursively. I.e., also
the child configs of a sub-init of a sub-init of the top-level init
receive a config check.

1b4128d3d9 Adapt sub_rm test to current Linux 32-bit
As noted above the former enum for the local-attachment address we
discovered address clashes on current Linux installations, esp. 32-bit
runtime on 64-bit Linux. The local_attach_addr is now configurable in
the run script and the memory maps heuristics were removed.

4e97a6511b hw: switch page-tables only when necessary
* Instead of always re-load page-tables when a thread context is switched
  only do this when another user PD's thread is the next target,
  core-threads are always executed within the last PD's page-table set
* remove the concept of the mode transition
* instead map the exception vector once in bootstrap code into kernel's
  memory segment
* when a new page directory is constructed for a user PD, copy over the
  top-level kernel segment entries on RISCV and X86, on ARM we use a designated
  page directory register for the kernel segment
* transfer the current CPU id from bootstrap to core/kernel in a register
  to ease first stack address calculation
* align cpu context member of threads and vms, because of x86 constraints
  regarding the stack-pointer loading
* introduce Align_at template for members with alignment constraints
* let the x86 hardware do part of the context saving in ISS, by passing
  the thread context into the TSS before leaving to user-land
* use one exception vector for all ARM platforms including Arm_v6

42db1e112b hw: introduce kernel/user address space split
* introduces central memory map for core/kernel
* on 32-bit platforms the kernel/core starts at 0x80000000
* on 64-bit platforms the kernel/core starts at 0xffffffc000000000
* mark kernel/core mappings as global ones (tagged TLB)
* move the exception vector to begin of core's binary,
  thereby bootstrap knows from where to map it appropriately
* do not map boot modules into core anymore
* constrain core's virtual heap memory area
* differentiate in between user's and core's main thread's UTCB,
  which now resides inside the kernel segment

b811ef4331 signal: fix starvation by fast signal contexts
In the past, a signal context, that was chosen for handling by
'Signal_receiver::pending_signal and always triggered again before
the next call of 'pending_signal', caused all other contexts behind
in the list to starve. This was the case because 'pending_signal'
always took the first pending context in its context list.

We avoid this problem now by handling pending signals in a round-robin
fashion instead.

28004bc9e6 timer: limit rate of handling timeouts
Ensure that the timer does not handle timeouts again within 1000
microseconds after the last handling of timeouts. This makes denial of
service attacks harder. This commit does not limit the rate of timeout
signals handled inside the timer but it causes the timer to do it less
often. If a client continuously installs a very small timeout at the
timer it still causes a signal to be submitted to the timer each time
and some extra CPU time to be spent in the internal handling method. But
only every 1000 microseconds this internal handling causes user timeouts
to trigger.

If we would want to limit also the call of the internal handling method
to ensure that CPU time is spent beside the RPCs only every 1000
microseconds, things would get more complex. For instance, on NOVA
Time_source::schedule_timeout(0) must be called each time a new timeout
gets installed and becomes head of the scheduling queue. We cannot
simply overwrite the already running timeout with the new one.

ddfd3c0d7e linux: stack-area handling with recent Linux kernels
We moved the stack-area segment 128 MiB behind text and data to comply
with assumptions in the kernel ELF loader.

This commit also reenables static binaries on linux and removes the
unused stack_area.stdlib.ld script.

1d56c3d3aa base: remove non-critical quota messages
In nested scenarios like driver_manager.run, the initial session quota
for IO_PORT, IO_PORT, and IRQ sessions is expectedly insufficient.
However, the condition is properly handled by re-attemping the request
with a slightly increased quota. Still, core prints a warning each time
the request is denied for quota reasons, which spams the log. This patch
removes the non-critical message.
