a528aa097a init: add 'label' criterion for session routing
This patch introduces a shortcut for conditional session routes of the
form '<if-arg key="label" value="..."/>'. With this change, the label
can be directly specified as 'label' attribute of an '<any-service>' or
a '<service>' node. The '<if-arg>' mechanism was not documented anyway
and I hope to be able to ultimately remove it.

ceb04d3c11 nova: avoid race in pager_object destruction
Don't skip the cleanup call if a pager object is marked as blocked.

It happens that the pager_object is in destruction but it is also used
concurrently by the pager thread. The pager thread handling code may set the
pager object to blocked but still uses the pointer to the pager object. Avoid
locking at the state of the pager object and make the cleanup call everytime.

Error output looks like this, where the pf_ip is within

  void Pager_object::_page_fault_handler(addr_t pager_obj)

method and the pf_addr is the stale pointer to the already released pager_object.

no RM attachment (READ pf_addr=xxx pf_ip=xxx from 00 <NULL>)
static void Genode::Pager_object::_page_fault_handler(Genode::addr_t): page fault, thread '<NULL>', cpu x, ip=xxx, fault address=xxx

2b429ee84c base: Dispatch server signal in entry point
Currently, when a signal arrives in the main thread, the signal dispatcher is
retrieved and called from the main thread, the dispatcher uses a proxy object
that in turn sends an RPC to the entry point. This becomes a problem when the
entry point destroys the dispatcher object, before the dispatch function has
been called by the main thread. Therefore, the main thread should simply send an
RPC to the entry point upon signal arrival and the dispatching should be handled
solely by the entry point.

ce354d6fd9 linux: improve diagnosis on exception handling
Under some circumstances, the diagnostic message in the exception signal
handler was not printed. This could happen due to a dead lock in the
console library if the console code itself produces the exception while
possessing the mutex, e.g., by exhausting a undersized stack. Now, we
directly write to the log session via the stdout_write() hook or use
raw_write_str() in core.

dce6e14e3e os: generalize Session_label, Session_policy
The utilities in os/session_policy.h used to be tailored for the
matching of session arguments against a server-side policy
configuration. However, the policy-matching part is useful in other
situations, too. This patch removes the tight coupling with the
session-argument parsing (via Arg_string) and the hard-wired use of
'Genode::config()'.

To make the utilities more versatile, the 'Session_label' has become a
'Genode::String' (at the time when we originally introduced the
'Session_label', there was no 'Genode::String'). The parsing of the
session arguments happens in the constructor of this special 'String'.
The constructor of 'Session_policy' now takes a 'Genode::String' as
argument. So it can be used with the 'Session_label' but also with other
'String' types. Furthermore, the implicit use of 'Genode::config()' can
be overridden by explicitly specifying the config node as an argument.

the returned stack pointer the x86_64 assembler implementation did not

on. Therefore, the Rom_session_component's constructor had to be modified
to not construct a dataspace component on the stack and assign it in the
following.

c1492da15b base: do not lock interleaved in object pool
Holding the object pool's lock while trying to obtain an object's lock
can leave to dead-lock situations, when more than one thread tries to
access multiple objects at once (e.g.: when transfer_quota gets called
simultanously by the init and entrypoint thread in core). To circumvent
holding the object pool lock too long, but access object pointers safely
on the other hand, this commit updates the object pool implementation
to use weak pointers during the object retrieval.

b585583ec7 core: do not destroy in object pool's apply scope
Destroying an object within the scope of a lambda/functor executed
in the object pool's apply function leads potentially to memory corruption.
Within the scope the corresponding object is locked and unlocked when
leaving the scope. Therefore, it is illegal to free the object's memory meanwhile.
This commit eliminates several places in core that destroyed wrongly in
the object pool's scope.

7e3bcb1e39 tcp_terminal: signal available bytes on partial read
If a client provides a read buffer of insufficient size for all
available data, we have two options

1) Leave it to the client to do partial reads until not further data is
   available, or

2) Signal the client that there still some bytes on a partial read.

As the second option seems more robust it's implemented in this commit.

9b21c88bc6 base: handle unsupported printf commands better
The commit consumes the argument of a unsupported printf command.

Without the commit - a subsequent command uses the argument of the preceding
command, which may cause memory corruption or page faults for sequences using
string commands, e.g.

Genode::printf("%#x %s\n", 0x20, "Test");

'#' is not supported by Genode::printf. In this scenario a pagefault at
address 0x20 is caused.

24b1f269be Remove Packet_ref from File_system::Packet_descriptor
The intention of Packet_ref was to allow clients to place opaque
references into the packet descriptor itself, which could be observed on
packet completion. Currently no component in our sources uses this
feature and beyond that it is questionable if it should be used at all:
If the server tampers with the ref the client may easily be confused
into observing an incorrect or invalid context. It seems better to
remove the opaque context from the descriptor and leave the actual
implementation to the client and its needs.

By default, the EMT thread of the last vCPU handles expired timers. When
running VirtualBox with 2 vCPUs, it sporadically happens that the EMT
thread of the second CPU clears an 'interrupt pending' flag for the first
vCPU after changing the state of a timer device model, which is not
expected by our Genode-specific code (failed assertion '!_irq_win' in the
recall handler).

The problem did not occur yet when letting the EMT thread of the first
vCPU handle the expired timers, which is done by this commit as an interim
fix until the problem has been further investigated.

There are currently some issue with the mixing/filtering code of vbox.
So instead of using the audio subsystem to do filtering and mixing we
bypass it to get better audio qualitiy. That means that the device
model of the VM has to use the same sample rate as the Audio_out/in
sessions, however.

5be5191645 vbox: enable preliminary audio support
With this commit preliminary audio support in VirtualBox is enabled.
The backend supports playback as well as recording sounds from within
a guest VM. Depending on how the guest configures the device model
the audio output may sound disorted. If the guest uses buffers that
are too small, i.e., 10 ms or less, frequent buffer underruns will
occure.

To get this low-latency one has also to increase vbox' update hz
to 200 (i.e., 5ms).

e8c9125d9f Pseudo target for vfs_jitterentropy
Run script depending on VFS plugins (i.e., shared objects) like
vfs_jitterentropy.lib.so have to state this dependency rather the actual
binaries linked against libc. The latter introduces a library dependency
that is just not there. For example, the dependency on vfs_jitterentropy
is a result from the config node for libc which automatically loads the
plugin.

26524edbf4 alarm: reposition reprogrammed alarms in queue
The alarm library failed to handle the case properly where an already
scheduled alarm gets rescheduled before it triggered. Even though the
attempt to reschedule the alarm (twice insertion into alarm queue) was
detected, this condition resulted in the mere modification of the
alarm's parameters while keeping the alarm's queue position unchanged.
This, in turn, may violate the invariant that all enqueued alarm objects
are strictly ordered by their deadlines. The patch handles the case by
dequeuing the alarm object before reinserting it into the queue at the
right position.

4992903233 Rename audio_out_drv to audio_drv
With the introducation of the Audio_in session interface it makes
sense to rename the current available audio drivers. At the moment
only the dde_bsd audio_drv supports Audio_out as well as Audio_in.
The Linux audio_drv only supports Audio_out (there is no demand for
Audio_in support currently) but is renamed nonetheless to make it
easiert to write generic run scripts.

8a34d21577 dde_bsd: add recording support to audio driver
The driver is now able to record audio samples. In contrast
to playback it has to be enabled explicitly by setting the
configuration attribute 'recording' to 'yes'. Playback is by
default enabled but may be disabled by setting 'playback' to
'no'. Furthermore it is now possible to configure the mixer
from the configuration. For now, the interface used by vanilla
OpenBSD is just exported.

The following snippet shows how to enable and configure recording
on an Thinkpad X220 where the headset rather than the internal
mic is used as recording source:

! <start name="audio_out_drv">
!   <resource name="RAM" quantum="8M"/>
!   <provides>
!     <service name="Audio_out"/>
!     <service name="Audio_in"/>
!   </provides>
!   <config recording="yes">
!     <mixer field="outputs.master" value="255"/>
!     <mixer field="record.adc-0:1_source" value="sel2"/>
!     <mixer field="record.adc-0:1" value="255"/>
!   </config>
! </start>

In addition to selecting the recording source the playback as
well as the recording volume are set to 255 (maximum).
Information about the available mixers and settings in general
may be obtained by setting the 'verbose' to 'yes' in the config
node.

Unfortunatly, there is no support for any HDMI/DP based HDA codecs in

PCI device on 00:03.00). This could also be done in the platform_drv's

61f5ca1e4d os: add Audio_in session for recording audio
In line with the Audio_out session a Audio_in session is used to
record audio frames. Like in the Audio_out session shared memory
in form of the Audio_in::Stream is used to transport the frames
from the server to the client. These frames consist of single
channel (mono) samples. An Audio_in::Packet always contains a full
period of frames.

A Audio_in server captures frames and puts them into the
Audio_in::Stream. To do so the server allocates a Audio_in::Packet
from the packet queue embedded in the Audio_in::Stream. If the queue
is already full, the server will override packets and notify the
client by submitting the 'overrun' signal. The client has to cope
with this situation, e.g., by saving packets more frequently.

A client will also receive a 'progress' signal from the server when
a new Audio_in::Packet was submitted to the packet queue.

This commit eliminates the mutual interlaced taking of destruction lock,
list lock and weak pointer locks that could lead to a dead-lock situation
when a lock pointer was tried to construct while a weak object is in
destruction progress.
Now, all weak pointers are invalidated and dequeued at the very
beginning of the weak object's destruction. Moreover, before a weak pointer
gets invalidated during destruction of a weak object, it gets dequeued, and
the list lock is freed again to avoid the former dead-lock.

463c9bec17 Replace Nic driver interface by customizable component
Removed the Nic::Driver implementation. All nic servers now inherit from
Nic::Session_component. Packet stream signals are dispatched to
the 'handle_packet_stream' function within a session component. Thus, nic
servers now have direct access to the packet stream channels, making handling
more flexible.

Adjusted nic_loobpack, dde_ipxe, wifi, usb, lan9118, Linux nic, and OpenVPN to
the new interface.

281d3ffba9 hw: free correct IRQ when closing IRQ session
The ~Irq_session_component relied on the IRQ number obtained by the
corresponding kernel IRQ object to mark the IRQ as free at the IRQ
allocator. However, since the kernel IRQ object is initialized not
before the 'sigh' function is called, the IRQ of sessions that
never called 'sigh' could not be freed correctly. This patch fixes
the problem by not relying on the kernel IRQ object for obtaining
the number in the destructor but using the '_irq_number' member
variable instead.

cc58b11998 hw: replace page table allocator with static one
Instead of organizing page tables within slab blocks and allocating such
blocks dynamically on demand, replace the page table allocator with a
simple, static alternative. The new page table allocator is dimensioned
at compile-time. When a PD runs out of page-tables, we simply flush its
current mappings, and re-use the freed tables. The only exception is
core/kernel that should not produce any page faults. Thereby it has to
be ensured that core has enough page tables to populate it's virtual
memory.

A positive side-effect of this static approach is that the accounting
of memory used for page-tables is now possible again. In the dynamic case
there was no protocol existent that solved the problem of donating memory
to core during a page fault.

e143084b04 base: fix warning in RPC framework
The recent change of the TRACE session interface triggered the
following warning:

/home/no/src/genode/repos/base/include/base/ipc.h:79:4: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]
    *reinterpret_cast<T *>(&_sndbuf[_write_offset]) = value;
    ^
In file included from /home/no/src/genode/repos/base/src/core/include/trace/session_component.h:19:0,
                 from /home/no/src/genode/repos/base/src/core/trace_session_component.cc:15:
/home/no/src/genode/repos/base/include/base/rpc_server.h:132:42: note: ‘ret’ was declared here
     typename This_rpc_function::Ret_type ret;

The warning occurs for basic return types (like size_t), which are
indeed not initialized. The variable gets its value assigned by the
corresponding 'call_member' overload, to which the variable is passed as
reference. But the compiler apparently is not able to detect this assignment.

Declaring 'ret' with a C++11-style default initializer fixes the warning.

5d678dba9e core: throw Trace::Out_of_metadata in subjects()
While importing trace sources as trace subjects into a TRACE session,
the session quota might become depleted. The TRACE session already keeps
track of the session quota via an allocator guard but the 'subjects' RPC
function missed to handle the out-of-memory condition. This patch
reflects the error condition as an 'Out_of_metadata' exception to the
TRACE client. It also contains an extension of the trace test to
exercise the corner case.

functions. However, if a dynamically linked program does not use the
libc (e.g., noux/minimal or the new version of cli_monitor), those
symbols remain unresolved. By adding them to ldso's symbol.map, the
dynamic linker will resolve them with the functions of the cxx
library, which is part of the dynamic linker.
