2baa283d87 vfs_lwip: reduce repeated warnings
This patch avoids the repeated warning "read blocked until lwIP
interface is ready" by printing the message only once. Otherwise,
the log is flooded with those warnings when falkon web browser
is started on Sculpt OS without network connectivity.

3ff0efd627 vfs/pipe: add fifo feature to pipe plugin
The vfs pipe plugin can now be used as named pipe which anables data
transfer via file handles from one component to another. E.g. if one
would like to send data from component A to stdin of a libc component B,
one can do so by simply writing to that fifo file.

19d9409a34 qemu-usb: adapt ISOCH IN handling for audio
Linux as well as Windows guests want queue to a varying number of
transfers, where each transfer only covers one transaction (iso frame).
The best results were obtained by following that behaviour rather
than queuing multiple iso frames per requests (like is done with OUT
transfers).

The number of requests queued is increased to 32 while the number of
packets per reques is decreased to 1.

9918a8f88d qemu-usb: update port to 5.2.0
The contrib code is updated from 2.4.1 to version 5.2.0 and the used
device-model is changed to QEMU xHCI. Due to this change older guests
OSes, namely Windows 7, that relied on the NEC xHCI device-model will
not work anymore.

The 'Qemu::Controller' interface was extended by an 'info' method, which
returns the vendor and product ID. This allows for removing the
hard-coded values in the VirtualBox glue code.

b51ae104c2 qemu-usb: use bounce buffer to access DMA memory
The former implemention assumed that the guest physical memory is
mapped continously. This, however, is not true. Writing larger
files to an USB stick with a Windows 10 guest would therefore lead
to data corruption.

The current implementation uses a bounce buffer to copy the data
to and from the guest physical memory and leaves dealing with the
memory mappings entirely up to the VMM.

a99f6a81b6 libc: clone 'environ' pointer value after fork
The 'environ' pointer is a global variable that must be considered as
part of the application state. It must be copied from the parent to the
child process during fork. Otherwise, a child returning from fork is
unable to access environment variables before invoking execve. The
actual environment variables and their values are already captured
because they reside at the application heap, which is cloned from the
parent. So the copied 'environ' pointer refers to valid data.

53081ac6b3 libc: Dont't use local_addr in try/catch block.
The code in Libc::Cloned_malloc_heap_range initializes its local_addr
member variable by calling Region_map::attach_at. This function can
throw Region_conflict exception. The handler for this exception uses the
local_addr to produce an error message. Such error log is IHMO
useless, or even incorrect since the value of local_addr is undefined

this code:

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.

a0fb944721 Propagate session diag flag to core
This commit restores the diag feature for selecting diagnostic output of
services provided by core. This feature became unavailable with commit
"base: remove dependency from deprecated APIs", which hard-wired the
diag flag for core services to false.

To control this feature, three possible policies can be expressed in a
routing target of init's configuration:

* Forcing silence by specifying 'diag="no"'
* Enabling diagnostics by specifying 'diag="yes"'
* Forwarding the preference of the client by omitting the 'diag'
  attribute

3d2b0cab93 libc: implement SNDCTL I/O control handling
In the same vein as the terminal and block I/O controls, the sound
controls are implemented via poperty files and match the OSS
API ([1] features a nice overview while [2] is v3 and [3] gives
in-depth information on the current v4.x API we eventually might want
to implement).

  [1] https://wiki.freebsd.org/RyanBeasley/ioctlref/
  [2] http://www.opensound.com/pguide/oss.pdf
  [3] http://manuals.opensound.com/developer/

The controls currently implemented are the ones used by the cmus OSS
output plugin, which was the driving factor behind the implementation.
It uses the obsolete (v3) API and does not check if the requested
parameter was actually set, which should be done according to the
official OSS documentation.

At the moment it is not possible to set or rather change any
parameters. In case the requested setting differs from the parameters
of the underlying Audio_out session - in contrast to the suggestion in
the OSS manual - we do not silently adjust the parameters returned
to the callee but outright fail the I/O control operation.

The following list contains all currently handled I/O controls.

  * SNDCTL_DSP_CHANNELS sets the number of channels. We return the
    available channels here and return ENOTSUP if it differs from
    the requested number of channels.

  * SNDCTL_DSP_GETOSPACE returns amount of playback data that can
    be written without blocking. For now it amounts the space left
    in the Audio_out packet-stream.

  * SNDCTL_DSP_POST forces playback to start. We do nothing and return
    success.

  * SNDCTL_DSP_RESET is supposed to reset the device when it is
    active before any parameters are changed. We do nothing and return
    success.

  * SNDCTL_DSP_SAMPLESIZE sets the sample size. We return the
    sample size of the underlying Audio_out session and return ENOTSUP
    if it differs from the requested number of channels.

  * SNDCTL_DSP_SETFRAGMENT sets the buffer size hint. We ignore the
    hint and return success.

  * SNDCTL_DSP_SPEED sets the samplerate. For now, we always return
    the rate of the underlying Audio_out session and return ENOTSUP
    if it differs from the requested one.

This commit serves as a starting point for further implementing the
OSS API by exploring more users, e.g. as VirtualBox/Qt5/SDL2 audio
backend or a more sophisticated progam like sndiod.

abefca500b libc: fix deadlock in pthread_cond_timedwait/signal()
The deadlock occured with three concurrently running threads: two
waiters calling pthread_cond_timedwait() and one signaller calling
pthread_cond_signal().

If waiter W1 hits its timeout, the signaller may have called
pthread_cond_signal(), detected this waiter and posted the internal
'signal_sem' concurrently. Then, the signaller waits for 'handshake_sem'
to ensure the waiter got woken up.

Waiter W1 can't consume the 'signal_sem' post by
'sem_wait(&c->signal_sem)' because another waiter W2 may have consumed
the post already above in sem_wait/timedwait(). Waiting for a post on
'signal_sem' would block the waiter W1 in perfect deadlock with
signaller on 'handshake_sem'. As W1 also owns 'counter_mutex' in this
situation, waiter W2 would block when trying to aquire 'counter_mutex'
and can't resolve the situation.

So, W1 does nothing in this case and we accept the spurious wakeup on
next pthread_cond_wait/timedwait().

There is a type mismatch as in the FreeBSD contrib code the type of the

falls into the signed range where used and this was not a problem.

Some of the SNDCTL requests, however, have the bit set.

e0d9a04f67 libc: resolve circular dependency in fork
This patch is a follow-up for the commit "libc: use monitor for fork".
It removes the use of the monitor mechanism from the

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.

This patch removes the now obsolete <nic/xml_node.h> header file.

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.

157f4b1270 pthread: implement condattr setclock
Normally CLOCK_REALTIME is used. However libraries, like glib, want to
use CLOCK_MONOTONIC. To make those users happy add setting the clock.

Note, the pthread_cond implementation uses the POSIX semaphore API
internally that does not have means to set the clock. For this reason,
the private 'sem_set_clock' function is introduced.

556a5c8086 libc: clean up 'clock_gettime' handling
This patch untangles the dependency of VFS operations that need RTC
information from the 'clock_gettime' libc function that must never be
called from the libc kernel context.

- The 'Rtc' class uses the VFS directly for reading the rtc file instead
  of relying on libc functions.

- The 'Rtc' instance has become part of the 'Kernel' instead of
  being construced as a side effect of the first call of
  'clock_gettime'.

- Changed 'Rtc::read' to return a timespec value, which has a higher
  precision than the formerly used time_t value.

- The 'Rtc::read' returns a value with the relative 'current_time'
  already applied. The former handling of subsequent rtc-value
  updates has been rewritten to become more logical.

- The 'Vfs_plugin' no longer calls 'clock_gettime' but the new
  kernel-level 'Current_real_time' interface.

852ab79359 Move atexit handling from base lib to libc
This patch untangles the interplay of the base library and the libc
during the exit handling.

- The CXA ABI for the atexit handling is now provided by the libc.
  For plain Genode components without libc dependency, __cxa_atexit
  is a no-op, which is consistent with Genode's notion of components.

- The 'abort' implementation of the base library no longer calls
  'genode_exit' but merely 'sleep_forever'. This way, the cxx library
  no longer depends on a 'genode_exit' implementation.

- The libc provides 'atexit' support by storing metadata on the
  libc kernel's heap now, thereby eliminating the former bounded
  maximum number of atexit handlers.

- Shared-library dtors are no longer called via the atexit mechanism
  by explicitly by the dynamic linker. This slightly changes the
  call order of destructors (adjustment of the ldso test). Functions
  marked as destructors are called after the atexit handlers now.

- The libc executes atexit handlers in the application context,
  which supports the I/O operations in those handles, in particular
  the closing of file descriptors.

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.
