b8cc468f02 base: support assignment of invalid weak_ptr
This fixes the region-map component implementation in core, which uses a
'Genode::Weak_ptr<Genode::Region_map_component> _faulting_region_map'
member. This member is assigned a valid weak_ptr or an invalid weak_ptr
according to the state machine.

7d641d5f1f base: add Reconstructible::conditional method
The new 'conditional' method simplifies the typical use case for
'Constructible' objects where the constructed/destructed state depends
on a configuration parameter. The method alleviates the need to
re-implement the logic again and again.

The patch also removes the 'Reconstructible' constructor arguments
because they are unused.

304cb290d9 nic_router: rework quota accounting
* Account all RAM/CAP quota of a session except quota for metadata used in
  core. The latter is considered when asking if a session can afford to make
  an operation but it does not get accounted to always be able to pay back all
  quota when a session closes. The general accounting mechanism is moved from
  atop of the allocators down to the level of RAM/RM session operations.
* report statistics about session objects and quota if <report stats="yes"
  quota="yes"/> is configured. (default is yes if <report> is present)

bd77bb41df nic_router: improve handling of TCP termination
Like suggested by RFC 2663, reprogram the dissolve timeout of a TCP link
state to 2 times the maximum segment lifetime (by default 1 minute) when
receiving a matching packet with the FIN flag set, or with the ACK flag
set to acknowledge a FIN of the remote side.

Mark a link state as closed (no further reprogramming of the dissolve
timeout) and set the dissolve timeout to 2 times the maximum segment
lifetime when receiving a packet with the RESET flag set.

d6c6549354 nic_router: destroy links on insufficient resource
If the NIC router has insufficient CAP or RAM quota for the creation of
a state object for an interface, it tries to destroy a certain amount of
existing state objects of this interface to free resources. Afterwards,
it retries handling the current packet once. If it does fail again, the
router drops the packet.

3824ad4756 nova: define kernel memory based on system memory
Switch to kernel branch, that determines the available system memory during
boot time. The overall kernel memory is still static, but during boot time
dynamically the amount can be chosen. Following 3 config option exists:

CONFIG_MEMORY_BOOT is the amount of kernel memory allocated in the BSS
statically - effectively chosen during link time - see linker script.

CONFIG_MEMORY_DYN_MIN && CONFIG_MEMORY_DYN_PER_MILL configures the dynamic
part of the kernel memory allocation applied during early kernel boot time.
CONFIG_MEMORY_DYN_MIN is the amount of memory which should be allocated at
least. CONFIG_MEMORY_DYN_PER_MILL defines the amount of the system memory in
per mill which should be allocated at most. The overall maximum kernel memory
is restricted to ~1G (64bit), due to the chosen internal virtual memory layout.

f4c55aa4db sculpt: interactive deployment
This patch introduces the distinction of the manually managed
config/deploy from the managed config/managed/deploy. The latter
incorporates interactive changes of the system by the user. There are
two user interactions supported.

First, by clicking on the '+' button at the top-left of the runtime
view, the user can select a component to launch. All launchers at
config/launcher/ are listed in the popup menu. Each launcher can be
lauched only once. While running, is not available in the popup
menu.

Second, when selecting a node that corresponds to a start node in
config/deploy or that was interactively launched, the detailed view
shows a 'remove' button, which can be used to exclude the component
from the deployment.

The result of the interactive manipulation is always available at
config/managed/deploy. Hence, the current situation can be made
persistent by using it as config/deploy.

040eae4806 wifi_drv: fix tasklet_schedule
The tasklet_schedule implementation was missing the unblock call, which
was no problem in the past because the correspending task would get un-
blocked by other work items. Now that every workqueue has its own task,
there is nobody left to unblock the task and thereby execute the
tasklet. As a tasklet is the only way to transmit any pending frames
after transmission was temporarily suspended - because the device/fw
was not able to process the TX request - this rendered 6xxx devices
unusable whenever this situation occurred.

090ba0e235 arora: call main function from dedicated thread
The Arora main thread sometimes blocks on a pthread condition variable,
which prevents Genode signal processing with the current implementation.
This is especially a problem when the thread who could unblock the main
thread calls 'Libc::suspend()'.

As a workaround until the pthread locking mechanisms get adapted to the
Genode libc execution model, the Arora main function can be called from
a dedicated thread.

98380cebda VFS LwIP: do not free TCP PCBs on error
The VFS LwIP plugin is page-faulting on connect error because the LwIP
library frees a failed TCP protocol control block before calling the
error callback, and then the VFS plugin dereferences the PCB to free it
a second time. This problem was caused by a failure to follow
documentation during a transition from a C callback to a C++ method.

cc4a72243d print_lines: fix bugs in line length calculation
1) The loop for determining the line length read from a character offset
   before checking whether the offset is smaller than the given string
   length. This could have caused access outside the string buffer.

2) The routine for determining the line length first seeked for the
   offset of the last real character of the line and than added one for
   getting the length but only if the following character was '\n'. This
   has to be done for any other line-terminating character too. The only
   case where you don't want to do this is when the end of the whole
   string is reached.

35f61475f5 libc_vfs: don't suspend in 'notify_read_ready()'
When 'notify_read_ready()' is called during 'select()' and fails,
suspending can cause a deadlock when the libc IO response handler becomes
active and calls 'select_notify()', which tries to acquire the
'select callback list lock', which is already acquired by the suspended
'select()' call.

It seems possible to ignore a failed 'notify_read_ready()' call instead of
suspending. When the VFS plugin calls the IO handler later when the
notification request can be processed, the 'select_notify()' call of the
libc IO response handler will eventually call 'notify_read_ready()' again.

6f8e8a6ea4 LwIP: clamp reads to a value that can be expressed in 16 bits
There is a bug in the LwIP VFS plugin, the chained buffers used by Lwip
use sizes expressed in sixteen bits, and under conditions such as a read
of 1<<16 the higher bits are lost and the plugin performs a zero length
read, and the application interprets this as a closed connection.

cdef4c2548 sculpt: runtime view
This patch adds a graph of the current runtime state to the
leitzentrale. The topology of the graph depends on the first routing
rule of each component. For this reason, the patch re-orders routing
policies to make the most important route the first in the list.

The user can switch between the runtime view and the inspect window
by clicking on the corresponding menu dialogs. E.g., a click on the
storage dialog reveals the inspect window.

25ee872703 sculpt: separate launchers from deploy config
The most important route of each launcher is at the top of routes and

By caching the state reports generated by the runtime init, the sculpt
manager becomes able to quickly check for the presence of components. So
we can apply routing-dependency checks not only prior starting
components but also while components are running.

3976a43c84 gems/vfs.h: make 'File_content' more robust
This patch addresses two problems: By guarding the buffer allocation in

constructor reverts the allocation. Second, if the file has no content
no allocation should be performed. The previous version wrongly passed
a size of zero to the allocator in this case.

d909715f1b input/ps2: drop fake right-shift scancodes
Seen on X250

Description from https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html

  The ten grey keys Insert, Home, PgUp, Delete, End, PgDn, Up, Left,
  Down, Right are supposed to function regardless of the state of Shift
  and NumLock keys. But for an old AT keyboard the keypad keys would
  produce digits when Numlock was on or Shift was down. Therefore, in
  order to fool old programs, fake scancodes are sent: when LShift is
  down, and Insert is pressed, e0 aa e0 52 is sent; upon release of
  Insert e0 d2 e0 2a is sent. In other words, a fake LShift-up and fake
  LShift-down are inserted.

7e08bba25c Cached_fs_rom: fix congestion error
When the cached_fs_rom saturates the packet stream of its File_system
session it will call the session request handler recursively as pending
transfers are completed. This is bad because the content of the XML node
currently being processed will change.

The session request handler can no longer be called directly, but the
"schedule" method will submit a signal to the request handler, and
requests will be processed after the current operation has completed.

e3005266b6 vfs: no 'handle_io_response()' in regular VFS functions
Calling 'handle_io_response()' in a regular VFS function (in contrast to a
post-signal hook) can cause problems if the caller of the VFS function holds
a lock which prevents the io response handler from returning.

With this commit, the user of the VFS becomes responsible for unblocking
threads which might be blocking after a failed 'queue_read()', 'queue_sync()'
or 'write()' call.

4b46abf813 base: rm first-class support for static binaries
This patch removes the detection of statically linked executables from
the base framework. It thereby fixes the corner cases encountered with
Sculpt when obtaining the binaries of the runtime from the depot_rom
service that is hosted within the runtime.

Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries
can still be started by relabeling the ROM-session route of "ld.lib.so"
to the binary name, pretending that the binary is the dynamic linker.
This can be achieved via init's label rewriting mechanism:

  <route>
    <service name="ROM" unscoped_label="ld.lib.so">
      <parent label="test-platform"/> </service>
  </route>

However, as this is quite cryptic and would need to be applied for all
lx_hybrid components, the patch adds a shortcut to init's configuration.
One can simply add the 'ld="no"' attribute to the <start> node of the
corresponding component:

  <start name="test-platform" ld="no"/>

fbe9d26c47 trace: initialize trace control in Thread::start
Previously, the trace control of a thread was initialized in its
constructor (which is generic for all components). This has the
disadvantage that the CPU-session-pointer member of the thread might not
be valid at this point. And it cannot be replaced by using the
"deprecated_env" CPU session neither as constructing the deprecated
environment in causes troubles in Core. But as the trace control
shouldn't be needed in Core anyway, the initialization can be moved to
the Thread::start implementation of non-core components. This code
already takes care of the CPU session pointer.

a3858bff3c base: handle cancelation of session creation
This patch improves the handling of the corner case where a client
vanishes while a session request is in flight (CREATE_REQUESTED but
not yet AVAILABLE). This corner case could be sporadically observed with
the init_loop test on base-linux.

In the original version, the session would eventually be delivered but
never picked up by anyone. Such a stale session still uses resources that
should better be released. In the new version, the parent checks for the
liveliness of the client whenever a session is delivered. If there is no
client of the session, a close request is immediately issued to the
server. The session state must be preserved until the close requests has
been answered.

3bbeacad20 init: preserve final state of exited children
This is a follow-up patch of "init: avoid too eager child restart". On
each config update of init, init re-applies child-specific configuration
changes. In the case of an already exited child, this re-evaluation
wrongly marked such a child as abandoned because the child's environment
sessions do no longer exist. Abandoning the child, in turn, triggers the
destruction and subseqent restart (because the <start> node of the
configuration still exists). The latter is bad for two reasons.

First, the exit state of the original instance becomes lost. Second, the
restart may have unexpected side effects due to sessions created by the
new instance. I.e., when resizing a partition in sculpt, init would
wrongly restart the gpt-write tool after the tool successfully exited.
This collides with a newly started instance of part_blk/resize2fs, which
now competes with the second gpt-write instance for the exclusive access
of the targeted block device.

The patch prevents init from re-applying configurations to exited
children. The accompanied test case covers the corner case.

The chroot server was conceived to automatically place File_system

a 'merge' policy would truncate the session label before path conversion.
Now that init can rewrite session labels and thus reproduce truncation,

49a3a0e0d0 nic_router: multiple uplinks
Introduce the uplink tag:

! <config>
!    <uplink label="wifi"  domain="uplink">
!    <uplink label="wired" domain="wired_bridge">
!    <uplink               domain="wired_bridge">
! <config/>

For each uplink tag, the NIC router requests a NIC session with the
corresponding label or an empty label if there is no label attribute.
These NIC sessions get attached to the domain that is set in their
uplink tag as soon as the domain appears. This means their lifetime is
not bound to the domain. Uplink NIC sessions can be safely moved from
one domain to another without being closed by reconfiguring the
corresponding domain attribute.

Attention: This may render previously valid NIC router configurations
useless. A domain named "uplink" doesn't automatically request a NIC
session anymore. To fix these configurations, just add

! <uplink domain="uplink"/>

or

! <uplink label="[LABEL]" domain="uplink"/>

as direct subtag of the <config> tag.

This patch weakens the aggressive restart of a child with incomplete

sequence of configurations with successively added start nodes.

97ea513122 nic_router: fix pure virtual call in ~Interface()
The interface destructor called pure virtual methods at least when
cancelling ARP- waiting states. The implementations were made by the
deriving classes Session_component respectively Uplink. This led to an
abort of the NIC router as the destruction of the derived class was
already done. A similar problem already occured in the past during the
construction of Interface and was back then solved by introducing a
separate init() method. This commit, however, solved the problem by
making Interface a member of the other classes. Therefore, the init()
method could be removed again. Furthermore, the interface polica could be
moved from Session_component_base to Session_component. The commit also
had to generalize the way the link state of an interface is determined.

b96f0fa2df init: defer immediate restart of abandoned child
While a child is abandoned, we must limit the start of anothers with
the same name. Otherwise - of the child has startup problems - a number
of abandoned children with the same name may queue up. This becomes a
problem whenever the child destruction depends on an asynchronous
service that provides an env session for the children. If the service is
unable to keep up with the session requests (both create and close),
the queue of abandoned children becomes unbounded. Limiting the child
creation rate to one abandoned child per name mitigates this problem.

slow depletion of the server's quota over time. This patch ensures that
the delivery of session quota is consistent with the information

578bec11ac base: fix quota reversing when clients vanish
The 'Child::_revert_quota_and_destroy' assumes to be called from the
client's context, which is normally the case when destroying sessions.
However, if a client's session outlives the client (because the
asynchronous close request to the server is still pending), the session
cleanup is performed in the context of the server. Here, the
'session_response' implementation wrongly called
'_revert_quota_and_destroy' to the effect that the session quota was
withdrawn from the server (good) but subsequently transferred back to
the server (bad). The patch replaces the call of
'_revert_quota_and_destroy' with only the first - correct - part of the
transaction.

Previously we were doing the initialization once over all domains,
remembered which of them became invalid and destroyed those afterwards.
This isn't sufficient. As soon as one domain becomes invalid we have to
dissolve/destroy this one, deinitialize all other domains again (as they
could contain references to the invalid domain) and retry to initialize
them from the beginning. We proceed with this until we have one run
without a domain becoming invalid. Then we can be sure that the last
initialization run did not create references to any invalid domain.
