tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

systemd-activate: Add support for datagram sockets core: Add flexible way to provide socket type the socket type should be a diffrent argumet in make_socket_fd . In this way we can set the socket type like SOCK_STREAM SOCK_DGRAM in the address. journal-remote: modify make_socket_fd

journal: unbreak sd_journal_sendv Borked since commit 3ee897d6c2401effbc82f5eef35fce405781d6c8 Author: Lennart Poettering <lennart@poettering.net> Date: Wed Sep 23 01:00:04 2015 +0200 tree-wide: port more code to use send_one_fd() and receive_one_fd() because here our fd is not connected and we need to specify the address.

journal-remote: split-mode=host, remove port from journal filename When constructing the journal filename to store logs from a remote host, remove the port of the tcp connection, as the port will change with every reboot/connection loss between sender/reveiver machines. Having the port in the filename will cause a new journal file to be created for every reboot or connection loss. For the implementation, a new argument "bool include_port" is added to the getpeername_pretty() function. This is passed to the sockaddr_pretty() function. The value of the include_port argument is set to true in all calls of getpeername_pretty(), except for 2 calls in journal-remote.c, where it is set to false.

basic: include only what we use This is a cleaned up result of running iwyu but without forward declarations on src/basic.

tree-wide: sort includes in *.h This is a continuation of the previous include sort patch, which only sorted for .c files.

socket-util: move CMSG_FOREACH() from macro.h to socket-util.h

socket-util: move remaining socket-related calls from util.[ch] to socket-util.[ch]

util-lib: move ether_addr_to_string() into ether-addr-util.c

socket: Set SO_REUSEPORT before bind() bind() fails if it is called before setting SO_REUSEPORT and another process is already binded to the same addess. A new reuse_port option has been introduced to socket_address_listen() to set the option as part of socket initialization.

build-sys: split internal basic/ library from shared/ basic/ can be used by everything cannot use anything outside of basic/ libsystemd/ can use basic/ cannot use shared/ shared/ can use libsystemd/
