2016-06-23fstab-generator: ignore root=/dev/nfs (#3591)Harald Hoyer
root=/dev/nfs is a legacy option for the kernel to handle root on NFS. Documentation for this kernel command line option can be found in the kernel source tree: Documentation/filesystems/nfs/nfsroot.txt

2016-06-23build-sys: move fdset.[ch] src/basic → src/shared (#3580)Lennart Poettering
It makes use of the sd_listen_fds() call, and as such should live in src/shared, as the distinction between src/basic and src/shared is that the latter may use libsystemd APIs, the former does not. Note that btrfs-util.[ch] and log.[ch] also include header files from libsystemd, but they only need definitions, they do not invoke any function from it. Hence they may stay in src/basic.
2016-06-23execute: add a new easy-to-use RestrictRealtime= option to unitsLennart Poettering
It takes a boolean value. If true, access to SCHED_RR, SCHED_FIFO and SCHED_DEADLINE is blocked, which my be used to lock up the system.
2016-06-23execute: be a little less drastic when MemoryDenyWriteExecute= hitsLennart Poettering
Let's politely refuse with EPERM rather than kill the whole thing right-away.
2016-06-23execute: set PR_SET_NO_NEW_PRIVS also in case the exec memory protection is usedLennart Poettering
This was forgotten when MemoryDenyWriteExecute= was added: we should set NNP in all cases when we set seccomp filters.
2016-06-23execute: use the return value of setrlimit_closest() properlyLennart Poettering
It's a function defined by us, hence we should look for the error in its return value, not in "errno".
2016-06-23core: when writing transient unit files, make sure all lines end with a newlineLennart Poettering
This is a fix-up for 2a9a6f8ac04a69ca36d645f9305a33645f22a22b which covered non-transient units, but missed the case for transient units.

2016-06-22machinectl: do not escape the unit name (#3554)Elias Probst
Otherwise starting a machine named `foo-bar-baz` will end up in machinectl attempting to start the service unit `systemd-nspawn@foo\x2dbar\x2dbaz` instead of `systemd-nspawn@foo-bar-baz`.
2016-06-22watchdog: Support changing watchdog_usec during runtime (#3492)Minkyung
Add sd_notify() parameter to change watchdog_usec during runtime. Application can change watchdog_usec value by sd_notify like this. Example. sd_notify(0, "WATCHDOG_USEC=20000000"). To reset watchdog_usec as configured value in service file, restart service. Notice. sd_event is not currently supported. If application uses sd_event_set_watchdog, or sd_watchdog_enabled, do not use "WATCHDOG_USEC" option through sd_notify.

Fix console log color
2016-06-22pid1: initialize status color mode after setting up TERMFranck Bui
Also we had to connect PID's stdio to null later since colors_enabled() assume that stdout is connected to the console.
2016-06-22pid1: initialize TERM environment variable correctlyFranck Bui
When systemd is started by the kernel, the kernel set the TERM environment variable unconditionnally to "linux" no matter the console device used. This might be an issue for dumb devices with no colors support. This patch uses default_term_for_tty() for getting a more accurate value. But it makes sure to keep the user preferences (if any) which might be passed via the kernel command line. For that purpose /proc should be mounted.

2016-06-20Revert "do not pass-along the environment from the kernel or initrd"Franck Bui
This reverts commit ce8aba568156f2b9d0d3b023e960cda3d9d7db81. We should pass an environment as close as possible to what we originally got.
2016-06-20pid1: reconnect to the console before being re-executedFranck Bui
When re-executed, reconnect the console to PID1's stdios as it was the case when PID1 was initially started by the kernel.

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.

Systemctl fixes
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
2016-06-14resolved: in the ResolveHostname() bus call, accept IP addresses with scopeLennart Poettering
When we get a literal IP address as string that includes a zone suffix, process this properly and return the parsed ifindex back to the client, and include it in the canonical name in case of a link-local IP address.

Previously, after checking the local zone for a reply and finding one we'd not initialize the answer ifindex from that. Let's fix that.

Apparently newer gcc versions are a bit more forgiving when assigning an "unsigned char*" pointer to something of a different type. Let's add the missing cast so that old gcc versions are fine, too.
2016-06-14systemctl: allow percent-based MemoryLimit= settings via systemctl set-propertyLennart Poettering
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.
