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.
Fix#1607
The timer driver on X86 needs CPU quota with highest priority as it
frequently has to interrupt the counters to update the PIT.
On ARM this makes no difference in the test results as ARM timer
drivers, once configured, can sleep until the end of the timeouts.
On X86 we raise the error tolerance to 2% (default 1%) to compensate
the error caused by the timer.
Fixes#1621
Printing all errors and the goal values instead of exiting at the first
error allows for faster analysis of problems with the CPU-quota
mechanism.
Ref #1616
The test always succeeded because I forgot to set the error tolerance from
my debugging value 1 back to the correct value 0.01 before commiting the
test.

Adjust bomb to specify the various hard-coded parameters and set up bomb.run
this way that it manages at our test machine to succeed in the given time.
Issue #1615
Add a test where a locked pointer shall be taken during object destruction.
Moreover, extend the run-script so it runs on different platforms with
"real" timers.
Init used to specify the unique child name as session label when
requesting the binary image of a dynamically linked child. The actual
module name was propagated as "filename" session argument. Since we want
to move towards the sole use of the session label, which can be taken
into account for the session routing, the module name should always be
the last part of a ROM session label.
This patch changes the window manager, the decorator, and the
floating window layouter to propagate the usage of an alpha channel from
the client application to the decorator. This way, the decorator can
paint the decoration elements behind the affected windows, which would
otherwise be skipped.
This patch changes the way how CLI monitor obtains its subsystem
configurations. Originally, this information was provided via the
Genode::config mechanism. But for managing complex scenarios, the config
node becomes very complex. Hence, it is preferrable to have a distinct
file for each subsystem configuration.
The CLI monitor scans the directory '/subsystems' for files ending with
".subsystem". Each file has the same syntax as the formerly used
subsystem nodes.
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.
Fixes#1602
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.
This patch enable clients of core's TRACE service to obtain the
execution times of trace subjects (i.e., threads). The execution time is
delivered as part of the 'Subject_info' structure.
Right now, the feature is available solely on NOVA. On all other base
platforms, the returned execution times are 0.
Issue #813
This patch bases the size of the destination buffer in
'Init::Child_policy_redirect_rom_file' on the maximum label size
instead of the filename size. Otherwise, the use of a long configfile
name (i.e., "trace_subject_reporter.config") in combination with a long
child name ("trace_subject_reporter") would result in a truncated label
string.
When replacing a report with a smaller one, the corresponding ROM
dataspace should not contain any traces of the old report. Otherwise,
the consumer of the ROM dataspace may mistake the stale content as
meaningful information. This is particularly annoying when manually
inspecting reports. This patch overwrites the stale content with zeros.
By appending a newline to the generated XML data, we prevent the output
from messing with the command prompt when using 'cat' on a shell.
Futhermore, when using line-buffered output, the trailing newline
ensures that the output gets gets properly flushed.
This patch moves the VFS file-system factory to a separate vfs library
that is independent from libc. This enables libc-less Genode programs to
easily use the VFS infrastructure.
Fixes#1561
