42fddf8390 Cleanup shared-object support mechanics
The former ldso-startup static library (now called ldso_so_support) is
used to spice each shared object/library with local support code for the
dynamic linker (execution of static constructors and ARM-EABI).
Therefore, the library must be statically linked to each dynamic
library.

As a result recipes for dynamic libraries must always depend on the "so"
API, which makes ldso_so_support.mk and so_support.c available
independent of "base". Additionally, ldso_so_support is also provided in
the libc API to cut the dependency early for libc/posix libraries.

9d67f9fc8e Remove Allocator_guard
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.

The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.

The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.

f0c4fc1e22 sandbox: defer requests for upcoming server
The sandbox library supports the forwarding of session requests from the
outside to one of the hosted children according to a policy. This patch
introduces the distinction between two cases, which previously triggered
the denial of the session request.

- There exists no matching policy for the requested session
- There exists a matching policy but the referred server child
  does not exist (yet)

Whereas the proper response to the first case is the denial of the
request, the second case can occur in situation where a dynamic init is
used to implement a staged startup, for example via the deploy
mechanism. In such cases, a policy may exist as a static rule while the
server has not been started yet. This patch changes the behavior such
that such requests are stalled.

The patch is accompanied with test cases for exercising both situations.

150d143755 os: use Request_stream API in NVMe driver
As a result of the API change the memory handling could be simplified.
Since the Block session dataspace is now directly used for DMA, we
actually only have to provide the memory for setting up PRP lists for
large requests (for the moment more than 8 KiB of data).

As we limit the maximum data transfer length to 2 MiB, we get by with
just a page per request. Those memory is allocated beforehand for the
maximum number of I/O requests, which got bumbed to 512 entries. Since
not all NVMe controllers support such large a maximum data transfer
length and this many entries, especially older ones, the values are
capped according to the properties of the controller during
initialization. (The memory demands of the component are around 3 MiB
due to setting up for the common case, even if a particular controller
is only able to make use of less.)

(Although there are controllers whose maximum memory page size is more
than 4K, the driver is hardcoded to solely use 4K pages.)

In addition to those changes, the driver now supports the 'SYNC' and
'TRIM' operations of the Block session by using the NVMe 'FLUSH' and
'WRITE_ZEROS' commands.

0df358a550 nova: early message on successful boot
This patch fixes a regression with run/log_core introduced by

  2064ffd64b nova: support multidimensional affinity space

The run tool uses a log message 'run_boot_string' to detect successful
boot as well as to detect unexpected reboots. This message should never
be logged twice and, thus, should not be part of the core_log. The patch
mentioned above moved the former run_boot_string after the core_log
initialization.

2912096f6e vfs: distinguish NO_PERM from NO_ENTRY in unlink
This patch changes the 'Single_file_system' to return NO_PERM only if
the to-be-unlinked file corresponds to the single file. This way, a
<rom> co-mounted with a <ram> file-system does not stand in the way of
unlinking files from the <ram>. The concrete symptom occurred the
following scenario:

  <vfs>
    <dir name="home">
      <ram/>
      <rom name="..."/>
    </dir>
  </vfs>

The following sequence of commands wrongly resulted in "Operation not
permitted":

 $ mkdir -p /home/a/b/c
 $ rm -f /home/a/b/c/d

In this case, rm should not fail (unlink should return ENOENT)

ba55409c86 nic_router: keep dyn IP when updating domain obj
When updating the domain object of interfaces that stay with the same domain
during a reconfiguration, until now, the normal "detach raw" function was used.
This caused the old domain object to discard a dynamic IP config as all
interfaces detached. This caused interfaces also to discard network links
established with the old configuration although it wasn't necessary. Thus, now
we use a dedicated "detach" in case that an interface actually stays with its
domain. This new "detach" doesn't decrease the interface counter of the domain,
so, it'll not discard its dynamic IP config. If, however, during a
reconfiguration, there's no interface calling this function (all interfaces
move to another or no domain), the dynamic IP config is still discarded as
expected.

c1b6000248 nic_router: don't call DHCP client on requests
Until now, the DHCP client was called also for DHCP requests when an interface
had a domain but yet no IP config. Now, an interface distinguishes between DHCP
requests and replies first and then accordingly calls the DHCP server or the
DHCP client if they're available. This also prevents that the DHCP client has
to handle packet headers other than that of DHCP.

0a468a07a7 nic_router: fix lifetime of DHCP clients
Let the DHCP client be a constructible member of Interface that is constructed
only as long as the interface is attached to a domain with a dynamic IP config.
This prevents DHCP client timeouts from a period with dynamic IP config to
trigger after a reconfiguration to a static IP config. Furthermore, handle
DHCP-reply packets at an interface only when the DHCP client its constructed.
Otherwise drop such packets.

6d48b5484d hw: correct the ARM cache maintainance operations
This commit fixes the following issues regarding cache maintainance
under ARM:

* read out I-, and D-cache line size at runtime and use the correct one
* remove 'update_data_region' call from unprivileged syscalls
* rename 'update_instr_region' syscall to 'cache_coherent_region' to
  reflect what it doing, namely make I-, and D-cache coherent
* restrict 'cache_coherent_region' syscall to one page at a time
* lookup the region given in a 'cache_coherent_region' syscall in the
  page-table of the PD to prevent machine exceptions in the kernel
* only clean D-cache lines, do not invalidate them when pages where
  added on Cortex-A8 and ARMv6 (MMU sees phys. memory here)
* remove unused code relicts of cache maintainance

In addition it introduces per architecture memory clearance functions
used by core, when preparing new dataspaces. Thereby, it optimizes:

* on ARMv7 using per-word assignments
* on ARMv8 using cacheline zeroing
* on x86_64 using 'rept stosq' assembler instruction

96cde52838 vfs: make <rom> fs robust against invalid ROMs
An invalid ROM dataspace can occur, for example, when requesting a ROM
from the report_rom service before the first report was posted. Such a
<rom> node can still be useful if it's dynamic. E.g., it can be watched.
Hence, the corner case of an invalid ROM dataspace should be gracefully
handled instead of causing an abort.

presents an easy way to generate XML to be consumed locally.

The patch also add a deprecation mark to the original 'xml' accessor
because copying 'Xml_node' objects (here as return value) is dangerous.
The new 'with_xml_node' method should instead be used to access the XML
content stored in the buffer.

4622ddb46f nitpicker: add version attribute in clicked report
This patch addresses a corner case where the nitpicker focus is not
solely defined by mouse clicks or (exclusively) by a window manager, but
by a policy component that takes mouse clicks and other policy (e.g.,
a lock screen) into account. It ensures that each click that follows a
focus change (however initiated) results in a new "clicked" report even
when the report looks the same. To allow the policy component to
uniquely distiguish subsequent reports, the report features a new
'version' attribute.

c51b4b5742 New VFS plugin for emulating POSIX pipes
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.

In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.

The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin
and tests both local pipes and pipes hosted remotely in the VFS server.

interface changes) by Norman Feske.

9b7915facb vfs server: redesigned internal control flow
This patch reworks the VFS server to become easier to understand.

- The packet-stream handling is hidden from the node types.

- Introduced the notion of a "job" as an abstraction from the raw packet
  stream.

- The processing of requests is split into three phases:
  (1) accepting new jobs,
  (2) the execution of jobs, and
  (3) the delivery of acknowledgements.

- There is no longer a global fifo of pending nodes. Instead, each
  session has a fifo of "active" nodes, which are nodes that wait
  for the completion of jobs.

- The Io_node type no longer uses virtual functions as hooks for
  the derrived classes. Instead, it provides a number of utility
  functions.

- The control flow of the 'Io_progress_handler' is now the same as
  for the session-local packet-stream handler.

- Removed dependency from 'file_system/node.h', which is a relic
  from the ram_fs.

While reworking the code, the following semantic changes were made
additionally.

- The handling of SEEK_TAIL no longer overwrites the file content at the
  end of the file.

- Removed diagnostic message at session-creation time.

- Write loop for continuous files

23d21d77e9 vfs/terminal: detect user interrupts (control-c)
This patch equips the VFS terminal file system with the ability to
detect user interrupts in the incoming data stream, and propagate this
information via the new pseudo file '.terminal/interrupts'. Each time,
the user presses control-c in the terminal, the value stored in this
pseudo file is increased. Thereby, a VFS client can watch this file to
get notified about the occurrences of user interrupts.
