This patch improves the life-time management of socket descriptors and addresses several corner cases exposed by the 'bomb' test. The lookup and association of file descriptors with global IDs have been turned into an atomic operation. Otherwise, multiple threads interacting with the singleton 'ep_sd_registry' may override each other's associations. Closing the socket pair used for the reply channel has been implemented via the RAII pattern to capture all corner cases, in particular exceptions. If blocking operations are interrupted by signals, we throw a 'Blocking_canceled' exception. We preserve core's socket descriptor at 'PARENT_SOCKET_HANDLE' to avoid a corner case where the parent capability is going to dup2'ed to the same handle. Support for 'Thread_base::join' within core to enable leaving Genode via Control-C. |
