f3fcb5f56f Facility for reinitializing Platform_env
The new function 'Platform_env::reload_parent_cap' triggers a reload
of the parent capability and its respective resources. It is needed
during the bootstrap of a new process forked from an existing Noux
process.

42c21e4582 Console: don't use buf for '-' and '0' padding
As buf is not sized depending on the padding, if a huge padding is put
in buf then we could see an overflow.

e6f6defaca Test capability integrity
The test application tries to print a message using init's own LOG
session without permission.

This patch fixes #106.

9508cc0ed5 Fixed wrong sign extension in printf on 64 bit
This patch fixes printf errors caused by sign extension of values that
were supposed to be unsigned. Fixes #6. Also handles the case where
sizeof(long long) != sizeof(long).

210eb98598 Support const RPC functions with no arguments
Until now, the RPC framework did not support const RPC functions. Rather
than being a limitation inherent to the concept, const RPC functions
plainly did not exist. So supporting them was not deemed too important.
However, there are uses of RPC interfaces that would benefit from a way
to declare an RPC function as const. Candidates are functions like
'Framebuffer::Session::mode()' and 'Input::Session::is_pending()'.

This patch clears the way towards declaring such functions as const.
Even though the patch is simple enough, the thorough support for
const-qualified RPC functions would double the number of overloads for
the 'call_member' function template (in 'base/include/util/meta.h'). For
this reason, the patch does support const getter functions with no
arguments only. This appears to be the most common use of such
functions.

a107c89a8e Exceptions at construction time of dynamic objects
This patch implements the support needed to handle exceptions that occur
during the construction of objects dynamically allocated via the
'Allocator' interface. In this case, the compiler automatically invokes
a special delete operator that takes the allocator type (as supplied to
'new') as second argument. The implementation of this delete operator
has been added to the 'cxx' library. Because the operator delete is
called without the size of the object, we can use only those allocators
that ignore the size argument of the free function and print a warning
otherwise. The added 'Allocator::need_size_for_free()' function is used
to distinguish safe and unsafe allocators.

b1b59fe8a6 Support for building all libs via 'make lib'
Normally, the build system creates libraries as mere side effects of
building targets. There is no way to explicitly trigger the build of
libraries only. However, in some circumstances (for example for testing
the thorough build of all libraries) a mechanism for explicitly building
libraries would be convenient. This patch implements this feature. It
consists of two changes.

The new pseudo target at 'base/src/lib/target.mk' gathers all libraries
that are available in all repositories specified for the build directory
and makes its target depend on them. This way, by building 'lib', all
libraries would be traversed. However, in the (likely) situation that
those libraries include one or more invalid libraries (libraries with
unsatisfied build requirements), the build system would skip the target.

Hence, the second change introduces a new condition 'FORCE_BUILD_LIBS'
to the build system. By setting this variable to 'yes' in the 'target.mk'
file, we let the build system to traverse library dependencies for
all valid libraries regardless of the presence of any invalid library.

91f59690c4 Handle corner case in nested RM handling
When using an ELF image as returned from the iso9660 server, such an
image is represented as a managed dataspace composed of various portions
of one RAM dataspace, each portion attached with a different offset.
Now, when mapping the text segment of the ELF image (usually starting at
0x1000 within the image), the code mapped at 0x1000 may correspond to
any offset within the RAM dataspace used by the iso9660 server. In
particular, the src-fault address (the one within the RAM dataspace) may
be higher than dst-fault address (somewhere just above 0x1000 where a
page-fault occurred). Thereby, 'curr_rm_base' may become negative
during the reverse lookup of 'Rm_client::pager'. This corner case used
to let the 'Fault_area::constrain' function return an invalid fault
area, and thereby let the reverse lookup fail. The improved version
explicitly checks for the address overflow condition and tries to
constrain the dst fault address to the largest possible log2 page within
the positive address range.

3d5cfde313 Signal accounting in the explicit-reply path
Properly account signal count in the explicit-reply path (when source-
client gets immediately unblocked by 'signal_session_component::submit').
This patch prevents the delivery of superfluous signals with num == 0.

defd6a9b58 Use POSIX threads in Linux/Genode hybrids
- Let hybrid Linux/Genode programs use POSIX threads for the
  implementation of the Thread API.
- Prevent linkage of cxx library to hybrid Linux/Genode programs because
  the cxx functionality is covered by glibc.
