2016-06-21units: machined needs mount-related syscalls for its namespacing operationsLennart Poettering
Specifically "machinectl shell" (or its OpenShell() bus call) is implemented by entering the file system namespace of the container and opening a TTY there. In order to enter the file system namespace, chroot() is required, which is filtered by SystemCallFilter='s @mount group. Hence, let's make this work again and drop @mount from the filter list.
2016-06-21machinectl: interpret options placed between "shell" verb and machine nameLennart Poettering
Previously, we'd stop processing of the argument list immediately when hitting the "shell" verb. However, we really should continue processing options then, until we hit the machine name. Fixes: #3472

2016-06-21emergency.service: Don't say "Welcome" when it's an emergency (#3569)Lennart Poettering
Quoting @cgwalters: Just uploading this as an RFC. Now I know reading the code that systemd says `Welcome to $OS` as a generic thing, but my initial impression on seeing this was that it was almost sarcastic =) Let's say "You are in emergency mode" as a more neutral/less excited phrase. This patch is based on #3556, but makes the same change for rescue mode.

2016-06-18Ensure kdbus isn't used (#3501)Dave Reisner
Delete the dbus1 generator and some critical wiring. This prevents kdbus from being loaded or detected. As such, it will never be used, even if the user still has a useful kdbus module loaded on their system. Sort of fixes #3480. Not really, but it's better than the current state.

2016-06-16resolved: when restarting a transaction make sure to not touch it anymore ↵Lennart Poettering
(#3553) dns_transaction_maybe_restart() is supposed to return 1 if the the transaction has been restarted and 0 otherwise. dns_transaction_process_dnssec() relies on this behaviour. Before this change in case of restart we'd call dns_transaction_go() when restarting the lookup, returning its return value unmodified. This is wrong however, as that function returns 1 if the transaction is pending, and 0 if it completed immediately, which is a very different set of return values. Fix this, by always returning 1 on redirection. The wrong return value resulted in all kinds of bad memory accesses as we might continue processing a transaction that was redirected and completed immediately (and thus freed). This patch also adds comments to the two functions to clarify the return values for the future. Most likely fixes: #2942 #3475 #3484

2016-06-16systemctl: delay pager/polkit agent opening as much as possibleZbigniew Jędrzejewski-Szmek
In https://github.com/systemd/systemd/issues/3543, we would open the pager before starting ssh, and the pipe fd was "leaked" into the ssh child as the stderr fd. Previous commit fixes bus-socket to nullify stderr before launching the child, but it seems reasonable to also delay starting the pager. If we are going to croak when trying to open the transport, it seems better to do this before starting the pager. This commit would also fix #3543 on its own.
2016-06-16systemctl: make sure we terminate the bus connection first, and then close ↵Lennart Poettering
the pager (#3550) If "systemctl -H" is used, let's make sure we first terminate the bus connection, and only then close the pager. If done in this order ssh will get an EOF on stdin (as we speak D-Bus through ssh's stdin/stdout), and then terminate. This makes sure the standard error we were invoked on is released by ssh, and only that makes sure we don't deadlock on the pager which waits for all clients closing its input pipe. (Similar fixes for the various other xyzctl tools that support both pagers and -H) Fixes: #3543

2016-06-15load-fragment: ignore ENOTDIR/EACCES errors (#3510)Zbigniew Jędrzejewski-Szmek
If for whatever reason the file system is "corrupted", we want to be resilient and ignore the error, as long as we can load the units from a different place. Arch bug https://bugs.archlinux.org/task/49547. A user had an ntfs symlink (essentially a file) instead of a directory after restoring from backup. We should just ignore that like we would treat a missing directory, for general resiliency. We should treat permission errors similarly. For example an unreadable /usr/local/lib directory would prevent (user) instances of systemd from loading any units. It seems better to continue.

2016-06-14util-lib: rework get_process_cmdline() (#3529)Lennart Poettering
This reworks get_process_cmdline() quite substantially, fixing the following: - Fixes: https://github.com/systemd/systemd/pull/3512/commits/a4e3bf4d7ac2de51191ce136ee9361ba319e106c#r66837630 - The passed max_length is also applied to the "comm" name, if comm_fallback is set. - The right thing happens if max_length == 1 is specified - when the cmdline "foobar" is abbreviated to 6 characters the result is not "foobar" instead of "foo...". - trailing whitespace are removed before the ... suffix is appended. The 7 character abbreviation of "foo barz" is hence "foo..." instead of "foo ...". - leading whitespace are suppressed from the cmdline - a comprehensive test case is added

The unit files already accept relative, percent-based memory limit specification, let's make sure "systemctl set-property" support this too. Since we want the physical memory size of the destination machine to apply we pass the percentage in a new set of properties that only exist for this purpose, and can only be set.
