b078224753 Replace Genode::strncpy by Genode::copy_cstring
- Since Genode::strncpy is not 100% compatible with the POSIX
  strncpy function, better use a distinct name.

- Remove bogus return value from the function, easing the potential
  enforcement of mandatory return-value checks later.

0de54cddaa gdb_monitor: hide exceptions during create_thread
This patch is a workaround for the missing implementation of
'Pd_session::transfer_quota' interface by the GDB monitor's PD service.
The missing implementation becomes problematic with the changes of #3750
that enabled the cap-quota accounting for core's CPU service.

In regular scenarios without the GDB monitor, the client of
'Cpu_session::create_thread' deals with Out_of_caps or Out_of_ram by
upgrading the CPU session's cap and RAM quotas. This, in turn, results
in a sequence of 'transfer_quota' operations at the parent.

Since GDB monitor implements a custom PD service, these 'transfer_quota'
calls try to transfer quota between sessions provided by core and those
provided by the GDB monitor. This does of course not work. To fix this
issue, the GDB monitor needs a major overhaul. This patch side-steps
the problem by handing Out_of_caps and Out_of_ram from the debuging
target.

adb48b5c9e Libc: MSG_PEEK support
As discovered by Johannes Kliemann, peeking at buffered socket data
using 'recv' and 'MSG_PEEK' is not supported. Read a "peek" control file
from the socket directory to attempt to peek into buffers at the
socket_fs. Support for every feature of POSIX sockets cannot be
expected, but this one is trivial to implement.

f1427fc02a dde_bsd: remove configration attributes
The driver always opens the audio device in duplex mode, i.e.,
playback and recording. Setting the 'playback' or 'recording' attribute
only influnces the service announcement. Due to changes made in a more
recent OpenBSD release recording must be set enabled explicitly anyway.
Since we already provide the interface that mirrors the one used by
OpenBSD 1:1 in the configuration use that and the remove the additional
config attributes.

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.

If a "cat" tool as simple as the removed one is needed, it should be

did not!

64bc008c3a core: fix inconsistent state after failed 'trace'
This patch fixes the handling of the corner case where the allocation of
a trace buffer throws 'Out_of_caps' or 'Out_of_ram'. Under this
circumstance, the '_buffer' would still be flagged with the 'size',
which prevented any subsequent allocation attempt. This patch fixes the
problem by initializing the 'size' after the potentially throwing
allocation.

The problem triggered with the test-trace_logger after the accounting of
core's TRACE service (replacing the 'Allocator_guard' by
'Constrained_ram_allocator') became more accurate.

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.

132569d12b base-linux: socket descriptor caps for RPC
On Linux, Genode used to represent each RPC object by a socket
descriptor of the receiving thread (entrypoint) and a globally-unique
value that identifies the object. Because the latter was transferred as
plain message payload, clients had to be trusted to not forge the
values. For this reason, Linux could not be considered as a productive
Genode base platform but remained merely a development vehicle.

This patch changes the RPC mechanism such that each RPC object is
represented by a dedicated socket pair. Entrypoints wait on a set of
the local ends of the socket pairs of all RPC objects managed by the
respective entrypoint. The epoll kernel interface is used as the
underlying mechanism to wait for a set of socket descriptors at the
server side.

When delegating a capability, the remote end of the socket pair is
transferred to the recipient along with a plaintext copy of the
socket-descriptor value of the local end. The latter value serves as a
hint for re-identifiying a capability whenever it is delegated back to
its origin. Note that the client is not trusted to preserve this
information. The integrity of the hint value is protected by comparing
the inode values of incoming and already present capablities at the
originating site (whenever the capability is invoked or presented to the
owner of the RPC object).

The new mechanism effectively equips base-linux with Genode's capablity
model as described in the Chapter 3 of the Genode Foundations book.
That said, the sandboxing of components cannot be assumed at this point
because each component has still direct access to the Linux system-call
interface.

This patch is based on the extensive exploration work conducted by
Stefan Thoeni who strongly motivated the inclusion of this feature into
Genode.

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.

Fixes #3702.

585c4b8c69 hw: Add support for Qemu virt arm platforms.
This patch adds support for booting base-hw kernel on qemu-arm virt
machines. The arm_virt machine has 2GB of RAM, 2 Cortex A15 cores and
uses GICv2 interrupt controller. The arm_64_virt machine also has 2GB of
RAM, but has 4 Cortex A53 cores and uses GICv3. Both machines use PSCI
to boot additional CPU cores.

  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.

0f3ac4cb9f base-hw: let upgrade_cap_slab reflect Out_of_caps
This patch reflects the Out_of_caps exception from core to the client,
in addition to the already covered Out_of_ram exception. It thereby
eliminates a potential abort in core, which I observed with the
tool_chain_auto.run script:

  Kernel: RPC upgrade_cap_slab
  Error: Uncaught exception of type 'Genode::Quota_guard<Genode::Cap_quota>::Limit_exceeded'
  Warning: abort called - thread: entrypoint

In addition to propagating the exception, the patch add the client-side
exception-handling code to the base library.
