f8953de7ac nic_router: replace term "uplink" with "NIC client"
BREAKS CONFIG COMPATIBILITY:
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!

HOW TO ADJUST:
At each occurrence of the '<uplink ...>' tag in a NIC router configuration
replace the tag name 'uplink' with 'nic-client'. The rest of the tag stays the
same.

The term "uplink" for network interfaces in the router that have a NIC session
client as back end was introduced in a time when Uplink sessions didn't yet
exist. Now, they do and, although both an uplink and an Uplink session
normally describe a network session between router and network device driver,
they are based on two different service types (NIC and Uplink). This can easily
cause confusion when integrating the router (the <uplink> is not related to
Uplink sessions) or trying to understand its functioning (an 'Uplink' object
has nothing to do with the Uplink service).

Therefore, this commit introduces the more specific term "NIC client" for an
interface that is based on a NIC session requested by the router. This doesn't
imply any semantic changes at the NIC router. However, the commit also brings a
broader update of the router's README and removes the term "downlink" that was
used only in documentation to refer to interfaces backed by a NIC session
provided by the router. The term was only associated with this meaning because
it is the natural counterpart to an uplink. This isn't appropriate anymore as
the terms for interface types have moved to a more technical level.

The commit adjusts all scenarios in the basic Genode repositories properly.

2afae7e7c1 nic_router: uncaught exc. on handling link state
An interface that received a signal for a link-state change accessed its
domain reference without assuming that it could not be attached to a domain
at that moment. This caused the NIC router to crash with an uncaught exception
of type 'Net::Pointer<Net::Domain>::Invalid'. The commit adds a catch
directive for this exception resulting in the handler doing nothing if not
attached to any domain.

d06773b957 run/tz_vmm: remove usb_armory support
The test script failed during preparation of the on-target execution for
USB Armory with the following error:

! can't read "tz_vmm_block_irq": no such variable

Presumably, the script wasn't run anymore since the introduction of the
'tz_vmm_block_irq' variable for i.MX53 QSB. As we do not have infrastructure
for automated testing of the USB Armory and there seems to be not much
interest in using Genode on this platform, this commit simply removes the
support from the script.

8bc861ca71 nic_router: do not re-use ARP request as reply
So far, in order to create an ARP reply, the NIC router merely created a copy
of the corresponding ARP request and modified only those values that differ.
This approach has the disadvantage of re-using bad parameters from a broken
request. The specific use-case that made this visible was an early version of
the Pine board network driver that used to forward ARP requests with a greater
size than required. The ARP replies of the router re-used this size and
confused other network nodes with that. In general, the NIC router should
rely on the data of incoming packets the least possible. Therefore, with this
commit, the router creates a new ARP reply from scratch and uses only those
values required from the corresponding ARP request.

9384e075cb ipv4: get rid of C++ bitsets, add DF/MF flags
The former declaration of the IPv4 packet did not only use the questionable

"don't fragment" (DF) and "more fragments" (MF). This commit replaces the

2d017ad7b7 nic_router: guard against exception in free_ip
Adds try-catch-statement with diagnostic errors in Dhcp_server::free_ip in
order to guard against exceptions from the underlying bit allocator. These
exceptions should never happen given that the router is programmed correctly
and always feeds Dhcp_server::free_ip with sane arguments (which it should).
However, should this not be the case, we can assume that the failed IP freeing
indicates that the IP isn't allocated anyway and it's fine to continue using
the router. Furthermore, IP allocations are a mere client service and not
relevant for the integrity or safety of the router.

be644098d7 nic_router: fix exc. in Interface::handle_config_3
When Interface::handle_config_3 (third step of applying a new configuration to
interfaces) tried to detach the interface from the current IP config because
the old and new IP config differed, it did so using the new domain. The former
steps of the reconfiguration already installed the new domain reference at the
interface. Therefore, also the DHCP server of the new domain was used. This,
however caused uncaught exceptions because detaching from an IP config
includes dissolving all DHCP allocations. This dissolving of DHCP allocations
now operated on a DHCP server (the one of the new domain) that wasn't related
to the allocations and, in the worst case, caused an uncaught exception
because the IPs were out of its range.

That said, this commit ensures that detaching an interface from an IP config
is always done on the domain from which the IP config originated. Normally,
this is the domain the interface is attached to. But in the case of
Interface::handle_config_3, it is another - the former domain the interface
was attached to.

The commit also adapts the nic_router_dhcp_* tests in a way that they
reconfigure the router in a way that would trigger the uncaught exception
without the fix.

Adapts Dir_file_system::open_composite_dirs in a way that it returns "success"
when the leaf node of the path is an empty directory but "lookup failed", as

only the leaf node was empty.

The commit also adds a test for en empty root directory and empty
sub-directories to the fs_query run script.

49184fb938 net: circumvent stringop-overflow error
With the update to GCC 10, the compiler stopped with an error when compiling
places where a MAC address is copied from outside into a packed object using
the Net::Netaddress::copy method (e.g. in
Net::Arp_packet::dst_mac(Mac_address)):

! error: writing 6 bytes into a region of size 4 [-Werror=stringop-overflow=]

While trying to find a clean solution for this error, I found posts on
gcc.gnu.org and github that stated that the size calculations that cause these
errors are incorrect. Indeed, I could verify that the actual size of the two
regions was static and exactly the same in places were the error occured.

Furthermore, I couldn't find a way of making it more clear to the compiler
that the sizes are the same. By accident, we found that using the address of
the first element of the array that forms the second region instead of the
array address itself, somehow circumvents the error.

52e8c95321 net: fix packed-conversion compiler warning
With the update to GCC 10 the compiler used to warn when using the internet
checksum functions on packet classes (like in
Net::Ipv4_packet::update_checksum):

warning: converting a packed ‘Net::[PACKET_CLASS]’ pointer
         (alignment 1) to a ‘const uint16_t’ {aka ‘const short
         unsigned int’} pointer (alignment 2) may result in an
         unaligned pointer value

Apparently, the 'packed' attribute normally used on packet classes sets the
alignment of the packet class to 1. However, for the purpose of the
internet-checksum functions, we can assume that the packet data has no
alignment. This is expressed by casting the packet-object pointer to a pointer
of the new packed helper struct 'Packed_uint16' that contains only a single
uint16_t member before handing it over to the checksum function (instead of
casting it to a uint16_t pointer).

4e822436fc nic_router: use increasing src port for new nat
The NAT feature of the NIC router used to prefer re-using source ports that
have been freed recently. From an external server's perspective, if a client
dies and restarts, chances are high that the new connect arrives with the same
source-IP/source-port as the old connection. The server has to forcefully reset
the connection. If that happens a lot, the server may even start to ignore
further connections from this IP/port combination for a while as a mitigation.

This patch adds a continuous counter feature that makes sure that every new
port allocation will increment and result in a port that hasn't been used for a
long time.

The NAT feature of the nic_router is now more in line with RFC 6056 chapter 4.

dc8c899c1d Streamline platform-device API on ARM
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of

- Platform::Device       - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq  - interface for receiving device interrupts

The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.

0339318572 platform_session: cache arg for alloc_dma_buffer
This patch extends the 'Platform_session::alloc_dma_buffer' interface
with a 'Cache' argument that corresponds to the argument accepted by
'Ram_allocator::alloc', which is used by the platform driver under the
hood.

Since the x86 platform driver used to be hardwired to allocate DMA
buffers as UNCACHED, I adjusted all drivers by specifying the UNCACHED
argument. Right now, this is needed as a hint for core to steer the
allocation of I/O page tables. Once we eliminate the need for such hints
(by introducing an explicit 'Region_map::attach_dma' operation), we can
revisit the drivers individually because cached DMA buffers should
generally be fine on the x86 architecture.

b661459aca sandbox/init: parse config using 'List_model'
This commit replaces the hand-crafted config processing by the use of
the 'List_model' utility. This has the following advantages:

- The parsing follows a common formalism that makes the code
  easier to maintain and to understand. Several parts of the code
  had to be changed (for the better) to make it fit the list model
  approach. E.g., the child states have become more expressive
  and logical.

- In the common case, the XML data is traversed only once, which
  increases the parsing speed in dynamic scenarios.

- The code becomes easier to optimize. In particular, the patch skips
  the re-evaluation of the session routing if no service is affected
  by the config change.

The patch also revisits the init test by removing overly long sleep
phases and extending a few sleep phases that were too short when
executing the test on Qemu.

  overload instead of relying on a default argument.

- The 'align' argument has been changed from 'int' to 'unsigned'
  to be better compatible with 'addr_t' and 'size_t'.

9093c293cb sandbox: destroy 'Session_state' of local services
This patch adds the missing destruction of session-state objects of
local services when closing a session. Because of the missing
destruction, those session-state object remained part of the server
ID space. This becomes a problem once the backing store of the session
state object vanishes, that is when the client child gets removed from
the sandbox. Hence, the removal of a child with an open session to a
local service would lead to the corruption of the server ID space.

This patch adds the missing session.destroy() call.

935bb36fe4 base: fix child destruction while close requested
This patch fixes a corner case where a child is destructed while a
asynchronous close request to a sibling server is still pending.

The child immediately discarded the session ID as the end of the
close-session processing, assuming that this ID is never to be needed
again. The session-state continues to exist to handle asynchrous close
protocol with the server.

However, if the child is destructed at this point (before the server
responded to the session request), the destruction of the child would
not cover the discharging of the session state because the session state
was no longer be part of the client's ID space. So once the asynchronous
close response from the server came in, the session state contained
stale information, in particular a stale closed_callback pointer.

The patch fixes the problem by deferring the discarding of the client ID
to the point where the session state is actually destructed. So the
session of a pending close response is covered by the child destructor.

Thanks to Pirmin Duss for reporting this issue along with a test
scenario for reproducing it!

c0a7565c21 os: shim helper for safe routing of env sessions
This shim component can be used in case where env sessions of child
(i.e., child's PD session) must be routed to another child of init.

Without the shim, init would directly need to interact with these
sessions and would thereby make itself dependent of the server's
behavior. RPC calls to a server hosted as a child lead to all kinds of
problems such as livelock situations, and putting the robustness of init
at the whim of its child.

With the shim, init merely needs to bootstrap the shim component by
routing the shim's env sessions to core as usual. The server is only
used for the sessions for the actual application hosted atop the shim.

f6d195a9de nic drivers: provide optional Uplink-client mode
In order to perform a smooth transition from NIC drivers that act only as NIC
session clients to NIC drivers that act only as Uplink session clients, this
commit introduces an intermediate state in which all NIC drivers support both
modes. That said, a NIC drivers mode is now statically determined through a new
optional 'mode' attribute in the drivers <config> tag that can be set to either
'nic_server' (default value) or 'uplink_client'. Reconfiguring this attribute
at a driver doesn't have any effects. Whithout this attribute being set, all
NIC drivers will behave the same as they did before the commit. When set to
'uplink_client', however, instead of providing a Nic service, they request
an Uplink session whenever their network interface becomes "UP" and close the
session whenever their network interface becomes "DOWN".

1d2649b49a nic_router: act as "Uplink" server
Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.

are swapped. An Uplink client is the one that provides a network interface
(for instance, a NIC driver) whereas an Uplink server is the one that uses
that network interface (for instance, a networking stack).

Therefore, in contrast to the NIC session, MAC address and link state come from
the Uplink client. The link state is reflected through the lifetime of an
Uplink session: The client requests the session only when the link state is
"UP" and closes it whenever the link state becomes "DOWN" again. The MAC
address is transmitted from the Uplink client to the Uplink server as an
argument of the session request.

72801975cd nitpicker: defer hover changed while dragging
When holding at least one key or button, the hovering should never
change. In the previous version, this invariant was not enforced,
but the symptoms for eventual inconsistencies were masked by two

change of 'User_state::_hovered' while in dragged state.

7fbb245710 os: add VirtIO device helper classes.
To simplify writing native VirtIO drivers for Genode add helper classes
representing VirtIO device and queue. The queue implementation should
be platform independant. The device abstraction however is closely tied
to the VirtIO transport being used (PCI/MMIO). Both PCI and MMIO
implementations expose the same public API so the actual driver logic
should be the same regardless of which transport is used.

Its also important to note that the PCI version of Virtio::Device
currently does not support MSI-X interrupts. Unfortunately my kowledge
about PCI bus is very limited and my main area of interest was to get
VirtIO drivers working on virt_qemu ARM/Aarch64 platform. As such all
the VirtIO drivers I plan to submit will work with PCI bus, but might
not use some extended capabilities.

9bd548c4bd os: add platform_drv config generator for virt_qemu
The VirtIO device configuration on Qemu is dynamic. The
order and presence of different command line switches affects
base address and interrupt assignment of each device. One could
probably hard-code the necessary switches and resulting XML ARM
platform driver configuration in each run script, but this seems
like troublesome and hard to maintain solution.

This patch explores an alternative approach to the problem.
It implements a ROM driver which probes the address space region
Qemu virt machines assign to VirtIO MMIO devices and exposes the
result as XML via a ROM session. This XML output can be fed directly
as config to the generic ARM platform driver.

04821b1abc nitpicker: apply focus change w/o input events
This patch fixes the corner case where the keyboard focus is defined
independently from user interactivity, e.g., the activation of a
screensaver or lock screen.

In this case, nitpicker would update its internal focus state not before
the next input event is handled. Should this input event be a press
event, this event would wrongly be delivered to the prior focused
session. Another problematic situation is the initial state before the
very first input event occurs. Since the focus remains undefined until
the first input event is handled, an initial key press event would not
be delivered.

This is a regression caused be the transition to the event-session
interface and the removal of the nitpicker's periodic way of operation.
The patch fixes the problem by applying pending focus changes not only
at the input processing but also on the code path that responds to focus
changes (e.g., focus-rom update).

2eb8c5e21a net: move ascii_to() into Net namespace
The combination of Net::Mac_address and
Genode::ascii_to(Net::Mac_address) required shaky quirks in several
places because GCC is not able to resolve the ascii_to overload if
base/xml_node.h was included to early. The current solution moves the
several ascii_to overloads "closer" to the Net types by putting them
into the Net namespace, where GCC reliably picks them up.

Hence, co-locating the ascii_to() utility with the overload type in the
same scope/namespace is good practice.

328a4fa644 nitpicker: update hovering on view-stack changes
With the change of nitpicker to the event session interface, the
formerly periodic hovering updates moved to the - now sporadic - input
processing. This has the unfortunate side effect that hovering changes
caused by non-user-input, in particular view-stack changes issued by the
GUI clients that change the view under the current pointer position,
would no longer be reported immediately but only after receiving the
next incoming input event.

This patch reworks the hover handling such that potential hovering
changes due to view-stack operations are evaluated immediately by
those operations, covering the update of the hover report and the
generation of artificial enter/motion events.

17a6318ad6 vfs: process all acks in each iteration
This patch solves a corner case where one long-active job (e.g.,
read-ready request) stays at the beginning of the '_active_jobs' queue
without an ack. In this case, the '_try_acknowledge_jobs' method would
wrongly stop processing the subsequent acknowledgements. In practice,
this can lead to a delayed sending of acknowledgements until new I/O or
client requests occur. In particular, Vim in Sculpt's inspect window
sometimes did not immediately respond to key presses during tab
completion. Here, the read-ready request of the terminal prevented the
acknowledgement for read of directory entry from being delivered until
the next key was pressed.

This is a temporary workaround to not harm drivers, which aren't
converted yet to request all device resources including power and
clocks from this new platform driver.

06edc0d52b base: extend PD session with managing_system call
Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.

The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.

d21bc8268b vfs: add raw option to terminal plugin
When the 'raw' attribute is set to 'yes' the terminal VFS plugin will
ignore control characters. This in necessary for terminal connections
that transport data that contain such characters as part of message.

Fixes #3860.

c7d9b2ca92 nitpicker: fix mode change for requested fb
This is a follow-up commit to "nitpicker: make framebuffer and input
optional". It restores the dynamic mode-change support when using
'request_framebuffer="yes"' as needed in scenarios where multiple
nitpicker instances are used in a cascaded way. E.g., Sculpt's
Leitzentrale. The previous version missed to reconstruct the
'_fb_screen' on mode changes.

2e22498e5a nitpicker: no framebuffer and input by default
This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.

For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".

9662d89cfb Replace input filter with event filter
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.

The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.

The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.

c502e1d095 input_filter: prepare for refactorization
This patch brings the input filter into a shape that is easier to
re-mold into an event filter, reversing the client/server roles of
the component.

* The 'Sink &destination' is no longer passed as constructor argument
  to the individual filters but passed as argument to the 'generate'
  method. This way, the final destination does not need to exist at
  the construction time of the filter chain but can be created on
  the fly (clearing the way for using 'Event::Client::with_batch').

* A new 'Source::Filter' interface with the 'apply' method aids the
  cascading of filters during 'generate'. The modules now implement
  the 'Source::Filter::filter_event' interface instead of the
  'Source::Sink::submit_event' interface.

* Since the 'Sink &destination' is no longer a member of the filter
  modules, character-repeat events can no longer be emitted in an
  ad-hoc way. Instead, the character-repeat mechanism now invokes
  a new 'Trigger::trigger_generate' hook that prompts the execution
  of the regular 'generate' mechanism by the main program.

This patch is supposed to leave the semantics of the input filter
unchanged (validated by the input_filter.run script).

7bac1ec7e5 Adapter for connecting input and event servers
This is an intermediate helper component for the transition of input
servers into event clients. It works analogously to the
input_event_bridge but it connects servers instead of clients.
In particular, it can act as glue between a traditional input driver
that provides an input service and the event filter that provides an
event service. Thanks to this component, each driver can be migrated to
the event-client interface individually.
