2015-10-08machined: when opening a shell via machined, pass tty fds inLennart Poettering
With this change we'll open the shell's tty right from machined and then pass it to the transient unit we create. This way we make sure the pty is opened exactly as long as the transient service is around, and no longer, and vice versa. This way pty forwarders do not have to deal with EIO problems due to vhangup, as the pty is open all the time from the point we set things up to the point where the service goes away.

2015-10-07util: always enforce O_NOCTTY and O_CLOEXEC in openpt_in_namespace()Lennart Poettering
The child process is shortliving, hence always set O_NOCTTY so that the tty doesn't quickly become controlling TTY and then gives it up again. Also set O_CLOEXEC, because it's cleaner, and doesn't affect the parent anyway.

cache harddisk passwords in the kernel keyring
2015-10-07basic: fix env expansion for strings leading with two dollar signsMichal Schmidt
The way to escape a literal dollar sign is to write "$$". But this does not work right if it's at the beginning of the argument. Fix it.
2015-10-07ask-password: add support for caching passwords in the kernel keyringLennart Poettering
This adds support for caching harddisk passwords in the kernel keyring if it is available, thus supporting caching without Plymouth being around. This is also useful for hooking up "gdm-auto-login" with the collected boot-time harddisk password, in order to support gnome keyring passphrase unlocking via the HDD password, if it is the same. Any passwords added to the kernel keyring this way have a timeout of 2.5min at which time they are purged from the kernel.

2015-10-07smack: label /etc/passwd and friends as '_' smack label when ↵Sangjung Woo
--with-smack-run-label' is enabled systemd-sysusers.service unit creates system users and groups and it could update /etc/passwd, /etc/group, /etc/shadow and /etc/gshadow. Those files should have '_' smack label because of accessibility. However, if systemd has its own smack label using '--with-smack-run-label' configuration, systemd-sysusers process spawned by systemd(pid:1) has its parent smack label and eventually updated files also is set as its parent smack label. This patch fixes that bug by labeling updated files as '_' smack label when --with-smack-run-label' is enabled.

Add support for naming fds for socket activation and more
2015-10-06core: add support for naming file descriptors passed using socket activationLennart Poettering
This adds support for naming file descriptors passed using socket activation. The names are passed in a new $LISTEN_FDNAMES= environment variable, that matches the existign $LISTEN_FDS= one and contains a colon-separated list of names. This also adds support for naming fds submitted to the per-service fd store using FDNAME= in the sd_notify() message. This also adds a new FileDescriptorName= setting for socket unit files to set the name for fds created by socket units. This also adds a new call sd_listen_fds_with_names(), that is similar to sd_listen_fds(), but also returns the names of the fds. systemd-activate gained the new --fdname= switch to specify a name for testing socket activation. This is based on #1247 by Maciej Wereski. Fixes #1247.

2015-10-05hashmap: hash_funcs - make inputs unambiguousTom Gundersen
Make sure all variable-length inputs are properly terminated or that their length is encoded in some way. This avoids ambiguity of adjacent inputs. E.g., in case of a hash function taking two strings, compressing "ab" followed by "c" is now distinct from "a" followed by "bc".
2015-10-05hashmap: refactor hash_funcTom Gundersen
All our hash functions are based on siphash24(), factor out siphash_init() and siphash24_finalize() and pass the siphash state to the hash functions rather than the hash key. This simplifies the hash functions, and in particular makes composition simpler as calling siphash24_compress() repeatedly on separate chunks of input has the same effect as first concatenating the input and then calling siphash23_compress() on the result.

2015-10-05siphash24: move last compression iteration from compression step to ↵Tom Gundersen
finalization step The last compression is special as it deals with the length byte, and padding. Move it to the finalization step in preparation for making compression decomposable.

2015-10-01logind: remove warn_melody() logicLennart Poettering
The internal speaker is usually not available on modern latops that support suspend, and even if it is available in the hardware, most distributions turned support for it off in the kernel. And even if it is enabled, it's probably still a bad idea to make use of it for the suspend-failures. If anything a proper sound should be played. Long story short, let's remove support of this anachronism.

2015-09-30tree-wide: clean up log_syntax() usageLennart Poettering
- Rely everywhere that we use abs() on the error code passed in anyway, thus don't need to explicitly negate what we pass in - Never attach synthetic error number information to log messages. Only log about errors we *receive* with the error number we got there, don't log any synthetic error, that don#t even propagate, but just eat up. - Be more careful with attaching exactly the error we get, instead of errno or unrelated errors randomly. - Fix one occasion where the error number and line number got swapped. - Make sure we never tape over OOM issues, or inability to resolve specifiers

2015-09-30log: properly return -EINVAL from log_set_max_level_from_string()Lennart Poettering
If we just return the value we got from log_level_from_string() on failure we'll return -1, which is not a proper error code. log_set_target_from_string() did get this right already, hence let's fix this here too.
2015-09-30fileio: make get_status_field() more genericAaro Koskinen
All users of get_status_field() expect the field pattern to occur in the beginning of a line, and the delimiter is ':'. Hardcode this into the function, and also skip any whitespace before ':' to support fields in files like /proc/cpuinfo. Add support for returning the full field value (currently stops on first whitespace). Rename the function so it's easier to ensure all callers switch to new semantics.

2015-09-29core: rework crash handlingLennart Poettering
This introduces a new systemd.crash_reboot=1 kernel command line option that triggers a reboot after crashing. This also cleans up crash VT handling. Specifically, it cleans up the configuration setting, to be between 1..63 or a boolean. This is to replace the previous logic where "-1" meant disabled. We continue to accept that setting, but only document the boolean syntax instead. This also brings the documentation of the default settings in sync with what actually happens. The CrashChVT= configuration file setting is renamed to CrashChangeVT=, following our usual logic of not abbreviating unnecessarily. The old setting stays support for compat reasons. Fixes #1300
