505d30cc42 Update ping tests
On real hardware, the tests expect an IPv4 subnet such that UDP requests
to 10.0.0.2 port 12345 get answered with an ICMP destination port unreachable.

Issue #2775

Issue #2788

Set DHCP discover timeout to 1 second because, for some reason, the first
DHCP discover attempt of the NIC router on the PandaBoard times out with the
nightly test infrastructure.

ce57319e4b nic_router: bind uplink session lifetime to domain
Normally, the NIC sessions are independent from the domain tags.
However, by now the uplink session, in contrast to the sessions of the
other domains, is still not a server but a client. This means that only
the NIC router itself can decide when to open and close uplink sessions
and how many. Thus, with this commit, we break with the pattern that
session lifetime is independent from domains by letting the NIC router
create the uplink session when the uplink domain appears and close the
session when the domain disappears.

7085640f05 nic_router: remove 'mac_first' attribute
Since the router MAC is allocated like the donwlink MACs it can't happen
anymore that these MACs clash, for instance due to nested routers. Thus,
the range of the MAC allocators of nested routers must not be exclusive
anymore which deprecates the 'mac_first' configuration attribute.

e83f095fd2 nic_router: downlinks use own router MAC address

41dbad13e4 nic_router/nic_bridge: re-work Mac_allocator
The old MAC allocator had several drawbacks:

* the address base was a public static that could and must have been written
  directly from outside the class
* the in-use-flag array was based on unsigned values consuming 4 bytes each
  for only one bit of information
* it was a public header that we actually don't want to expose to all
  components but only to the few networking components
* it used the not-so-safe bit notation for integer members of GCC

The new version fixes all these drawbacks.

980f3e9c5c net: use Size_guard for packet-data accessors
Instead of handing over the maximum available size to the packet data
accessors, hand over a size guard that keeps track of the packets
boundaries.

This commit also moves the size-guard utilitiy header of Ping and NIC
Router to the include/net directory making it a part of the net library.
It applies the new approach to all net-lib users in the basic repositories.

Ping looses its configurability regarding the ICMP data size as this would
require an additional method in the size guard which would be used only by
Ping.

The size guard was also re-worked to fit the fact that a packet can
bring a tail as well as a header (Ethernet).

11a297b557 net: consider tail of Ethernet frame
The Ethernet payload may be followed by padding of variable length and
the FCS (Frame Check Sequence). Thus, we should consider the value
"Ethernet-frame size minus Ethernet-header size" to be only the maximum
size of the encapsulated IP packet. But until now, we considered it to
be also the actual size of the encapsulated IP packet. This commit fixes
the problem for all affected components of the Genode base-repository.

the advantage that, when composing a new packet, the default constructor

6389434222 input_filter: rm input selection in output node
This patch largely reverts the feature of selecting parts of input nodes
from within the output node (as originally introduced by commit
7263cae5a18b4f1f2293d031f9bafcf05ba51146). The selection of content
should be consistently performed by input nodes instead. The principle
ability of copying input nodes verbatim into the output stays available.

1f1302e185 terminal: use VFS-based font handling
This patch replaces the terminal's formerly built-in fonts with the new
VFS-based font handling.

To avoid the copying of the terminal's font configuration across run
scripts, this patch adds the new terminal/pkg runtime package, which
includes everything needed for instantiating a terminal: the actual
terminal component, the library dependencies (vfs_ttf, which in turn
depends on the libc), a font (bitstream-vera), and a reasonable default
configuration.

6a12a6b4ba vfs: reduce ROM-update rate Rom_file_system::stat
The 'stat' method is called for all paths, not just the specific file
system node of the ROM module. The ROM update is needed only in the
latter case.

Otherwise, when always updating the ROM on stat, stat calls on the VFS
become very expensive in the presence of a mounted ROM module if the ROM
is obtained from fs_rom (which re-watches the file and all its
individual path elements whenever the 'update' RPC function is called).

9d233b73a3 nitpicker: improve 'Session::focus' handling
Nitpicker's 'Session:focus' call used to trigger a one-off focus change
at call time. This focus change did not pass the same code paths as a
focus change triggered by a "focus" ROM update, which led to
inconsistencies.

This patch changes the implementation of 'Session::focus' such that the
relationship of the caller and the focused session is preserved after
call time. Whenever the calling session is focused in the future, the
specified session will receive the focus instead. So 'Session::focus'
represents no longer a single operation but propagates the information
about the inter-session relationship. This information is taken into
account whenever the focus is evaluated regardless of how the change is
triggered.

This makes the focus handling in scenarios like the window manager more
robust.

93a0c66589 timeout: do not handle timeouts while scheduling
To handle all pending timeouts in the context of scheduling a timeout
was only necessary because the Timeout framework once made use of the
Alarm framework. The method Alarm_scheduler::schedule_absolute took an
absolute deadline as argument and we couldn't change this beause the
Alarm framework was also used without the Timeout framework. We had to
calculate this absolute deadline with the now time of the Timeout
framework but the Alarm framework has its own now time that is always a
bit behind the one of the Timeout framework. This lead to bad decisisons
when finding the right position for the new timeout. Now, we can call
schedule_absolute with a relative duration and thereby fix the problem.

When we schedule an absolute timeout without considering the small time
difference, the end-time for the timeout that is calculated using the
local time value is also smaller than the expected end-time. This can
also lead to directly triggering timeouts that should have triggered
with a certain delay.

As it is not trivial to update the local time value while scheduling a
timeout _without_ calling other timeout handlers, we simply raise the
duration of the new timeout by the age of the local time value.

f152e3e9d0 timeout: dequeue all pending alarms before reschedule
This fixes the problem that large timeouts, when rescheduled, are interpreted
to be from the last now_period instead of, what would be right, the next
now_period. This occured if there were multiple pending alarms at the head of
the queue and the reschedule of the first one was done with the other outdated
deadlines still in place.

bfb96536da timeout: _setup_alarm calculates deadline itself
Instead of taking the absolute deadline of a timeout as argument from
outside (where it is calculated with a freshly requested now time), we
now take a relative duration as argument and calculate the deadline with
the scheduler-internal now time (which can be a little bit outdated).
This enables us to schedule timeouts without updating the internal now time
and thereby handle all pending timeouts.

The dns_server_from attribute of the dhcp-server tag has effect only if
the dns_server attribute of the same tag is not set. If this is the
case, the dns_server_from attribute states the domain from whose IP
config to take the DNS server address. This is useful, for instance, if
the stated domain receives the address of a local DNS server via DHCP.
Whenever the IP config of the stated domain becomes invalid, the DHCP
server switches to a mode where it drops all requests unanswered until
the IP config becomes valid again.

Until now, the DHCP server of a domain was re-constructed each time the
IP config changed. This is not necessary as a domain that acts as DHCP
server must have a static IP config as it would be senseless to act as
DHCP server and client at the same time. Now, a configured DHCP server
is constructed only when the Domain gets constructed and stays alive
until the domain gets destructed. Furthermore, we now throw Domain::Invalid
if there is no static IP config plus a DHCP server configured. However, by
now, this exception is not caught as it is not trivial to destruct the
domain at this point.

92a30e0953 nic_router: handle configuration changes
The router reacts as follows to a configuration change:

1) Construct new internal configuration representation (the old one stays
   in place to be able to do comparisons in the following steps)
2) Iterate through all user-dependent objects (interfaces, link states, ARP
   information, DHCP information) and re-check which remain valid with the
   new configuration and which must be dismissed.
3) Adapt the objects that remain valid to the new configuration (re-write
   references) and remove or detach the dismissed objects.
4) Do a link state DOWN at each interface and a link state UP at each
   interface that remains attached to a domain.
5) Replace the old internal configuration representation with the new one

This way, the router keeps as much user dependent states as possible
while going through a configuration change. Thus, overwriting the old
configuration with an exact copy of itself is (almost) transparent to
clients of the router. Almost, because there are things the router must
do on every configuration handling, like re-scheduling the expiration
timeouts of links.

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.

accc7e7521 fs servers: handle result propagation better
This patch removes the notion of partial writes from the file-system
servers. Since write operations are asynchronously submitted, they are
expected to succeed completely, except for I/O errors. I/O errors are
propagated with the write acknowledgement but those are usually handled
out of band at the client side. Partial writes must never occur because
they would go undetected by clients, which usually don't wait for the
completion of each single write operation.

Until now, most file-system servers returned the number of written bytes
in the acknowledgement packet. If a server managed to write a part of
the request only, it issued the acknowledgement immediately where it
should have cared about writing the remaining part first.

The patch detects such misbehaving server-side code. If partial writes
unexpectedly occur, it prints a message and leaves the corresponding
request unacknowdleged.

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.

ccc67d6f68 trace_logger: convenient tracing frontend
The 'trace_logger' component can be used to easily gather, process and export
different types of tracing data. Which subjects to select is configurable via
session label policies and thread names. Which data to collect from the
selected subjects can be configured for each subject individually, for groups
of subjects, or for all subjects. The gathered data can be exported as log
output.

This is an example configuration of the 'trace_logger' component which shows
the default value for each attribute except the policy.thread and
policy.label:

! <config verbose="no"
!         session_ram="10M"
!         session_arg_buffer="4K"
!         session_parent_levels="0"
!         period_sec="5"
!         activity="no"
!         affinity="no"
!         default_policy="null"
!         default_buffer="4K">

!    <policy label="init -> timer" />
!    <policy label_suffix=" -> ram_fs" />

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.

f4a2d932e3 net: check packet data size in accessor
Instead of having a method validate_size in each packet class, check
sizes in the data accessor of the surrounding packet class. This packet
accessor is the one that casts the data pointer to the desired data type
so it is sensible that it also checks whether the desired type would
exceed the available RAM before doing the cast. This also fits nicely
the fact that for the top-level packet-class of a packet, the size must
not be checked (which was previously done).

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.

226c4a475b nic_router: do not warn on sending to empty domain
The warning "no interface connected to domain" was introduced when only one NIC
session at a time could be connected to a domain. It should help to track
packet drops that were caused by startup timing issues between servers and
clients. However, a user should watch the "NIC sessions" value of a domain
(verbose_domain_state) instead when debugging packet loss. With support for
multiple sessions per domain, even a non-empty domain may still miss the
session that connects the desired server.

57bfd09328 nic_router: no memcpy on self-written packets
Previously, all packets that the router wanted to sent were first prepared to
their final state and then copied at once into the packet stream RAM. This is
fine for packets that the router only passes through with modifying merely
a few values. But for packets that the router writes from scratch on its own,
it is better to compose the packet directly in the packet stream RAM.

b6991f9c03 nic_router: send with individual composing functor
Normally, Interface::send always takes the base and size of the RAM region
where a packet was composed and copies this finished packet at once into the
packet stream RAM. But we want to be able to also compose packets directly in
the packet stream RAM, so that no memcpy is needed. Thus, Interface::send now
takes a functor that describes how to compose the packet, then allocates the
packet stream RAM and applies the functor to this RAM. there is also a version
of Interface::send that provides the old behavior but with the new back end.
This way, we stay backwards-compatible.

c3853494c8 nic_router: domain-state-verbose flag
When this flag is set in the config tag, the NIC router will print a
short information to the log for each general state change of a domain.
This includes currently the IP-configuration state and the number of
connected NIC sessions. This a useful addition as the normal verbose
flag's purpose is a very deep insight into almost every activity in the
router, which is cool for debugging sophisticated problems but normally
floods the log and therefore discards this option for, e.g., desktop
systems. In such systems, the new verbosity is pretty discreet but
already gives a good hint on why packets may get dropped by the router
although the routing rules are correct.

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.

8fe0a7514f Nic::Session_component: pass entrypoint in constructor
Added a new constructor that takes the entrypoint as constructor
argument. The original constructor retrieves the entrypoint from the
Genode environment. This does not allow to use a different entrypoint.

3cdcb528ff nic_router: advanced timeout configuration
Replace former rtt_sec attribute of the <config> tag by more specific
(and still optional) attributes for timeouts used in the NIC router
(these are also the default values):

<config dhcp_discover_timeout_sec="10"
        dhcp_request_timeout_sec="10"
        dhcp_offer_timeout_sec="10"
        udp_idle_timeout_sec="30"
        tcp_idle_timeout_sec="600"
        tcp_max_segm_lifetime_sec="30">

Details about the new attributes can be found in the README of the router.

3d12e7b242 timeout x86_64 sel4: do not expect a precise time
On x86 64 bit with SeL4, the test needs around 80MB that must be
completely composed of 4KB-pages due to current limitations of the SeL4
port. Thus, Core must flush the page table caches pretty often during
the test which is an expensive high-prior operation and makes it
impossible to provide a highly precise time.

99ddaaa9d7 timer epit: fix multi-wraps and bug in rate limit
Multi-wraps
-----------

Previously, on every new timeout, we programmed registers LR=timeout and
CMP=0. The counter than counted from LR down to 0, triggered the IRQ,
jumped back to LR, and counted down again. If one installed small
timeouts (< 1000 us), it was likely that the counter wrapped multiple
times before we were able to read it out. Initially, this was not a big
issue as the additional wraps were simply ignored and the amount of time
lost through this was not big. But when we want to do correct rate
limitation, multiple wraps cause an overflow in the additional
calculations, and this has a big effect on the resulting time value.

Thus, we now program the counter to start from ~0 and count down to 0.
We set CMP=~0-timeout so that the timer still triggers the IRQ at the right
time. The counter continues counting down after the IRQ has triggered until
we install a new timeout. We do not consider anymore that the counter wraps.
The maximum timeout is set to half the maximum counter value, so, we should
be able to install a new timeout before the counter wraps.

Rate limit for time updates
---------------------------

In the time span between two interrupts we have to remember how many ticks
we have already added to the time value. This is because at each call of
curr_time we can only see how many ticks have passed since the last call of
schedule_timeout and not since the last call of curr_time. But we want to
limit the rate of time updates in curr_time. With the member for ticks that
were already added since the last call to schedule_timeout we can then
calculate how many are yet to be added.
