2016-07-22core: add a concept of "dynamic" user ids, that are allocated as long as a ↵Lennart Poettering
service is running This adds a new boolean setting DynamicUser= to service files. If set, a new user will be allocated dynamically when the unit is started, and released when it is stopped. The user ID is allocated from the range 61184..65519. The user will not be added to /etc/passwd (but an NSS module to be added later should make it show up in getent passwd). For now, care should be taken that the service writes no files to disk, since this might result in files owned by UIDs that might get assigned dynamically to a different service later on. Later patches will tighten sandboxing in order to ensure that this cannot happen, except for a few selected directories. A simple way to test this is: systemd-run -p DynamicUser=1 /bin/sleep 99999
2016-05-09util-lib: add new ifname_valid() call that validates interface namesLennart Poettering
Make use of this in nspawn at a couple of places. A later commit should port more code over to this, including networkd.

don't reopen socket fds when reloading the daemon
2016-05-06core: rework how we flush incoming traffic when a socket unit goes downLennart Poettering
Previously, we'd simply close and reopen the socket file descriptors. This is problematic however, as we won't transition through the SOCKET_CHOWN state then, and thus the file ownership won't be correct for the sockets. Rework the flushing logic, and actually read any queued data from the sockets for flushing, and accept any queued messages and disconnect them.
2016-05-05tree-wide: introduce new SOCKADDR_UN_LEN() macro, and use it everywhereLennart Poettering
The macro determines the right length of a AF_UNIX "struct sockaddr_un" to pass to connect() or bind(). It automatically figures out if the socket refers to an abstract namespace socket, or a socket in the file system, and properly handles the full length of the path field. This macro is not only safer, but also simpler to use, than the usual offsetof() + strlen() logic.

2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

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

2015-12-01journal-remote: split-mode=host, remove port from journal filenameKlearchos Chaloulos
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.

2015-07-01socket: Set SO_REUSEPORT before bind()Christos Trochalakis
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.
