This patch eliminates the "no attachment at..." warnings, which
were caused by a use-after-free problem of dataspaces. When a
dataspace was destroyed, the users of the dataspace were not
informed and therefore could not revert possible attachments to
RM sessions. The fix introduces a callback mechanism that allows
dataspace users (i.e., RM regions) to register for the event that
a dataspace vanishes.
The following types of dataspaces are handled:
* RAM dataspaces
* ROM dataspaces
* The process binary
* The binary of the dynamic linker
* Args dataspace
* Sysio dataspace
* Env dataspace
* managed RM dataspaces
The handling of ROM dataspaces is still not complete. When forking,
the ROM dataspace of the parent process gets just reused without
creating proper meta data ('Dataspace_info') for the forked process.
Similar issues might arise from other special dataspaces (e.g.,
args, env, sysio).
This patch removes all "no attachment at..." warnings except for
one (an attachment at 0).
Issue #485

This directory contains ports of popular 3rd-party applications to Genode. The 'ports' repository follows the line of the 'libports' repository. For instructions about downloading and building 3rd-party applications, please refer to 'libports/README'. Dependencies from other repositories ------------------------------------ Application provided by the 'ports' repository typically expect a rich runtime environment, including shared libraries provided by the 'libports' repository. Hence, 'ports' depends on 'libports'. Furthermore, applications may require additional repositories. For example, the Arora web browser depends on the 'qt4' repository.
