2016-12-21journald: don't flush to /var/log/journal before we get asked toLennart Poettering
This changes journald to not write to /var/log/journal until it received SIGUSR1 for the first time, thus having been requested to flush the runtime journal to disk. This makes the journal work nicer with systems which have the root file system writable early, but still need to rearrange /var before journald should start writing and creating files to it, for example because ACLs need to be applied first, or because /var is to be mounted from another file system, NFS or tmpfs (as is the case for systemd.volatile=state). Before this change we required setupts with /var split out to mount the root disk read-only early on, and ship an /etc/fstab that remounted it writable only after having placed /var at the right place. But even that was racy for various preparations as journald might end up accessing the file system before it was entirely set up, as soon as it was writable. With this change we make scheduling when to start writing to /var/log/journal explicit. This means persistent mode now requires systemd-journal-flush.service in the mix to work, as otherwise journald would never write to the directory. See: #1397
2016-12-21nspawn: restore --volatile=yes supportLennart Poettering
This was broken by 19caffac75a2590a0c5ebc2a0214960f8188aec7 which remounted the root directory to MS_SHARED before applying the volatile mount logic. This broke things as MS_MOVE is incompatible with MS_SHARED directory trees, and we need MS_MOVE in the volatile mount logic to rearrange the directory tree. Simply swap the order here, apply the volatile logic before we switch to MS_SHARED.

2016-12-21util-lib: various improvements to kernel command line parsingLennart Poettering
This improves kernel command line parsing in a number of ways: a) An kernel option "foo_bar=xyz" is now considered equivalent to "foo-bar-xyz", i.e. when comparing kernel command line option names "-" and "_" are now considered equivalent (this only applies to the option names though, not the option values!). Most of our kernel options used "-" as word separator in kernel command line options so far, but some used "_". With this change, which was a source of confusion for users (well, at least of one user: myself, I just couldn't remember that it's systemd.debug-shell, not systemd.debug_shell). Considering both as equivalent is inspired how modern kernel module loading normalizes all kernel module names to use underscores now too. b) All options previously using a dash for separating words in kernel command line options now use an underscore instead, in all documentation and in code. Since a) has been implemented this should not create any compatibility problems, but normalizes our documentation and our code. c) All kernel command line options which take booleans (or are boolean-like) have been reworked so that "foobar" (without argument) is now equivalent to "foobar=1" (but not "foobar=0"), thus normalizing the handling of our boolean arguments. Specifically this means systemd.debug-shell and systemd_debug_shell=1 are now entirely equivalent. d) All kernel command line options which take an argument, and where no argument is specified will now result in a log message. e.g. passing just "systemd.unit" will no result in a complain that it needs an argument. This is implemented in the proc_cmdline_missing_value() function. e) There's now a call proc_cmdline_get_bool() similar to proc_cmdline_get_key() that parses booleans (following the logic explained in c). f) The proc_cmdline_parse() call's boolean argument has been replaced by a new flags argument that takes a common set of bits with proc_cmdline_get_key(). g) All kernel command line APIs now begin with the same "proc_cmdline_" prefix. h) There are now tests for much of this. Yay!
2016-12-21util-lib: read $SYSTEMD_PROC_CMDLINE if set when looking for the kernel cmdlineLennart Poettering
if we want to parse the kernel command line, let's check the $SYSTEMD_PROC_CMDLINE environment variable first. This is useful for debugging purposes.
2016-12-20build-sys: don't mke use of "sushell" automaticallyLennart Poettering
"sushell" is a Fedora-specific concept, shipped as part of "initscripts". We shouldn't actively search for it if we can avoid it. Hence, lets now default to /bin/sh as debug shell on all systems, and permit Fedora to override that for their RPMs via --with-debug-shell= at configure time.
2016-12-20dissect: optionally, only look for GPT partition tables, nothing elseLennart Poettering
This is useful for reusing the dissector logic in the gpt-auto-discovery logic: there we really don't want to use MBR or naked file systems as root device.

2016-12-20core: modernize the SwitchRoot() bus method a bitLennart Poettering
Let's more verbose error messages when validating the input parameters fails. Also, call path_is_os_tree() properly, as it doesn't return a boolean, but possibly also an error. Finally, check for the existance of the new init process with chase_symlinks() to properly handle possible symlinks on the init binary (which might actually be pretty likely).

2016-12-20util-lib: beef path_is_os_tree() up a bitLennart Poettering
Let's use chase_symlinks() when looking for /etc/os-release and /usr/lib/os-release as these files might be symlinks (and actually are IRL on some distros).
2016-12-20util-lib: accept invoking chase_symlinks() with a NULL return parameterLennart Poettering
Let's permit invoking chase_symlinks() with a NULL return parameter. If so, the resolved name is not returned, and call is useful for checking for existance of a file, without actually returning its ultimate path.

We currently don't expect any warnings about format strings, on any architecture (#4612 removed the last few warnings). Turn those warnings into errors in the future. As requested by Martin Pitt. gcc documentation says that -Wformat=2 includes -Wformat-security and -Wformat-nonliteral so don't include them explicitly.

2016-12-17coredumpctl: let gdb handle the SIGINT signal (#4901)Franck Bui
Even if pressing Ctrl-c after spawning gdb with "coredumpctl gdb" is not really useful, we should let gdb handle the signal entirely otherwise the user can be suprised to see a different behavior when gdb is started by coredumpctl vs when it's started directly. Indeed in the former case, gdb exits due to coredumpctl being killed by the signal. So this patch makes coredumpctl ignore SIGINT as long as gdb is running.

2016-12-16core: make mount units from /proc/self/mountinfo possibly bind to a device ↵Franck Bui
(#4515) Since commit 9d06297, mount units from mountinfo are not bound to their devices anymore (they use the "Requires" dependency instead). This has the following drawback: if a media is mounted and the eject button is pressed then the media is unconditionally ejected leaving some inconsistent states. Since udev is the component that is reacting (no matter if the device is used or not) to the eject button, users expect that udev at least try to unmount the media properly. This patch introduces a new property "SYSTEMD_MOUNT_DEVICE_BOUND". When set on a block device, all units that requires this device will see their "Requires" dependency upgraded to a "BindTo" one. This is currently only used by cdrom devices. This patch also gives the possibility to the user to restore the previous behavior that is bind a mount unit to a device. This is achieved by passing the "x-systemd.device-bound" option to mount(8). Please note that currently this is not working because libmount treats the x-* options has comments therefore they're not available in utab for later application retrievals.

2016-12-16core: prevent invalid socket symlink target dereference (#4895)Stefan Hajnoczi
socket_find_symlink_target() returns a pointer to p->address.sockaddr.un.sun_path when the first byte is non-zero without checking that this is AF_UNIX socket. Since sockaddr is a union this byte could be non-zero for AF_INET sockets. Existing callers happen to be safe but is an accident waiting to happen. Use socket_address_get_path() since it checks for AF_UNIX.
