Volker Lendecke cf0c773ca5 messaging: Fix receiving file descriptors ... Don't close unconsumed file descriptors in messaging_recv_cb(). Via multiple registrations on different tevent contexts we might call messaging_recv_cb() multiple times: All but the first tevent context handled in the loop in msg_dgm_ref_recv() will not see file descriptors anymore, it will just get a -1, even if the first reference had no receiver interested in the fds. Change the API such that consumers can set the file descriptor to -1 if it's consumed. If nobody wanted them, do the close where they were created via recvmsg, in messages_dgm.c. If you want multiple handlers to consume the file descriptors, you should dup() them in the filter function handed to messaging_filtered_read_send and save the duplicate in your private data for later consumption.
