USB devices that are never associated to client sessions lack
usb_per_dev_data (and a kernel thread). Therefore, the devices should be
discontinued directly on unplug as no URBs can be pending.
Issue genodelabs/genode#4795
This commits enables the R8169 driver and was tested with two
RTL8168h/8111h (10ec:8168 rev 0x15 sub 1462:7a38 / 1d05:109f) and
two equal RTL8125B (10ec:8125 rev 0x5 sub 1458:e000) devices
running Sculpt.
Firmware loading is for now not implemented but specific Linux
commits suggest it could be necessary. However, doing so will be
post-poned until we have gathered more experience with the driver.
Restarting the driver might lead to the following IOMMU error
messages but the device seems to work anyway:

While this approach still scans "holes" in the bus range, it stops
scanning at the maximum subordinate bus number reachable from the base
PCI bus at the host bridge. Startup under Qemu no longer takes about 12
seconds for scanning 256 buses.
By splitting the 'init_capability_slab()' implementation to a separate
compilation unit 'capability_slab.cc', base-hw no longer needs a
customized version of 'lib/base/platform.cc'.

This patch replaces the internal use 'env_deprecated()' from the
implementation of the thread API in the base library. It also
replaces the global accessor 'main_thread_cap' by the explicit
propagation of the main-thread's capability to the single point of
use via a new 'init_thread_bootstap' function.

This back end can be used in place of the existing jitterentropy based
on in case random is not strictly needed by the component but one
wants to use the available 'shadow/drivers/char/random.c'
implementation.
Issue genodelabs/genode-allwinner#21.
The implementation was already part of the Zynq's sd_card driver and
since other ARM drivers need it as well, promote it to the common
shadow library.

* Removes all previous structs that represented an on-disc block layout
and were therfore subject to a number of layout restrictions (packed,
padding members, enum representations, etc.).
* Adds a replacement struct without any layout restrictions for each of the
removed structs. The new structs are named similar to the old structs.
* Adds block encoding and decoding utilities for easily converting from the
new structs to on-disc blocks and vice-versa (Block_scanner, Block_generator,
T::decode_to_blk, T::encode_from_blk)
* Adapts all affected places in the library to encode and decode proberly
instead of simply casting pointers.
* Thereby cleans up the hashing utilities to use typed-reference args instead
of void pointers.
* Re-enables run/tresor_tester and test-file_vault_vonfig_report for platforms
rpi, imx53_qsb, imx53_qsb_tz, imx6q_sabrelite, imx7d_sabre.

* Replaces bool access types with uint8_t access types
* Ensures, that the framework always uses the smalles possible uint type
for the return value wherever a bitfield is read and returned to the user.

In some instances, the fetchurl progress determined by
depot_download_manager will be empty when the download fails (e.g. due
to a 404), this commit fixes a bug where this would be interpreted as
the download having completed which would subsequently start hash
verification of a package that has never actually been downloaded.
Fixes#4919
The depot_remove component can delete PKG archives with
automatically resolving dependencies and deleting archives that are not
required on the system anymore.

On some platforms (x86_32/pistachio, x86_64/sel4) system startup is slow
and the previously configured 30 seconds not sufficient. With this commit, the
timeout is raised to 60 seconds only when running on such a platform.
Ref #4923
This test was originally a copy of ping.run and therefore unnecessarily
inherited all its complexity for testing ping component behavior. Additionally,
ping.run was more actively maintained and evolved over time whereas
nic_dump.run didn't receive the same care. Now, the test fails on certain
platforms although NIC dump works just fine. Therefore, this commit reduces the
test behavior to what is really necessary for testing nic_dump and by doing so,
also fixes the failing targets.
Fixes#4926
On x86_32 okl4, the test timed out although the test timeout was already at
240 seconds for this platform. Instaed of raising it further, this commit
reduces the number of ping rounds for all platforms that are considered as
slower by the test.
Ref #4923
This patch restricts 'Region_map::attach_executable' to create read-only
mappings, while offering the option to map the full rights using a new
'attach_rwx' method.
The 'attach_rwx' method is now used by the dynamic linker to explicitly
attach the linker area with full rwx rights. With the old page-fault
handling code, the execute flag was evaluated only for leaf dataspaces,
not for managed dataspaces while traversing region-map hierarchies.
With the new page-fault handling code, the execute bit is downgraded
to no-execute when passing a managed dataspace that is not attached
as executable.
Issue #4920
The change "core: allow offset-attached managed dataspaces" addressed a
corner case of the use of nested region maps. Apparently, this change
negatively affects other scenarios (tool_chain_auto).
In order to confidently cover all the differnt situations, this patch
reworks the page-fault resolution code for improved clarity and safety,
by introducing dedicated result types, reducing the use of basic types,
choosing expressive names, and fostering constness.
It also introduces a number of 'print' hooks that greatly ease manual
instrumentation and streamlines the error messages printed by core.
Those messages no longer appear when a user-level page-fault handler
is reistered for the faulted-at region map. So the monitor component
produces less noise on the attempt to dump non-existing memory.
Issue #4917Fixes#4920
The new monitor component at os/src/monitor is the designated successor
of the gdb_monitor. This initial version, however, implements only the
subset needed to inspect the memory of the monitored component(s).
In contrast to the gdb_monitor, the new component supports the monitoring
of multiple components, leveraging the sandbox API. It can therefore be
used as a drop-in replacement for the init component. Like the gdb_monitor,
the new monitor speaks the GDB protocol over Genode's terminal session.
But the protocol implementation does not re-use any gdbserver code,
sidestepping the complexities of POSIX.
There exist two run scripts illustrating the new component. The
os/run/monitor.run script exercises memory inspection via the 'm' command
by letting a test program monitor itself. The os/run/monitor_gdb.run
script allows for the interactive use of GDB to interact with monitored
components.
Issue #4917
Let the sandbox library disregard all unknown config sub nodes so that
supplemental information - like the monitor policy configuration - is
not interpreted as a misconfiguration ("unknown config element type ...").
