We collect all unix sockets in the current net namespace, but a target process uses a few of them, so we may skip unsupported sockets and if it is used by a target process, lookup_socket returns error. Signed-off-by:

This one is required on allocation -- it's already there as an argument. It's also required on free, but we can check for fd being >= 0. Signed-off-by:

Some process can share one struct file-s, we may find them by "object IDs". A file descriptor is opened in one process and send to other via unix socket. The procedure of restoring files contains four stages. * Collect data about all file's descriptors On this stage we find process which will restore a file descriptor and create a list of processes, who should get this descriptor. * Create datagrams unix sockets If a file descriptor should be received, a unix socket is created instead of it. * Open file descriptors A process with the least pid opens a file and sends this file descriptors to all one who wait it. * Receive file descriptors. When we were thinking up this algoritm, we wanted to minimize a number of context switches. A number of context switches is proportional of a number of processes. Signed-off-by:
