2016-11-15bus-util: print RestrictNamespaces= as a stringDjalal Harouni
Allow all callers that want to print RestrictNamespaces= returned from D-Bus as a string instead of a u64 value.

2016-11-15core:gperf: pass the exec_context struct directly to parse restrict namespacesDjalal Harouni
The RestrictNamespaces= takes yes, no or a list of namespaces types, therefor config_parse_restrict_namespaces() is a bit complex and it operates on the ExecContext, fix this by passing the offset of ExecContext directly otherwise restricting namespaces won't work.

The no_new_privileged_set variable is not used any more since commit 9b232d3241fcfbf60af that fixed another thing. So remove it. Also no need to check if we are under user manager, remove that part too.

2016-11-14nspawn: restart the whole systemd-nspawn@.service unit on container reboot ↵Zbigniew Jędrzejewski-Szmek
(#4613) Since 133 is now used in a few places, add a #define for it. Also make the status message a bit informative. Another issue introduced in b006762. The logic was borked, we were supposed to return 0 to break the loop, and 133 to restart the container, not the other way around. But this doesn't seem to work, reboot fails with: Nov 08 00:41:32 laptop systemd-nspawn[26564]: Failed to register machine: Machine 'fedora-rawhide' already exists So actually the version before this patch worked better, since 133 > 0 and we'd at least loop internally.

build-sys: do not install ctrl-alt-del.target symlink twice
2016-11-12build-sys: do not install ctrl-alt-del.target symlink twiceZbigniew Jędrzejewski-Szmek
It was a harmless but pointless duplication. Fixes #4655. Note: in general we try to install as little as possible in /etc/systemd/{system,user}. We only install .wants links there for units which are "user configurable", i.e. which have an [Install] section. Most our units and aliases are not user configurable, do not have an [Install] section, and must be symlinked statically during installation. A few units do have an [Install] section, and are enabled through symlinks in /etc/ during installation using GENERAL_ALIASES. It *would* be possible to not create those symlinks, and instead require 'systemctl preset' to be invoked after installation, but GENERAL_ALIASES works well enough.

2016-11-11systemctl: resolve symlinks when finding unit paths (#4545)Felipe Sateler
Otherwise we think the alias is the real unit, and may edit/cat the wrong unit.

2016-11-11units: disable /sys/fs/fuse/connections in private user namespaces (#4592)Zbigniew Jędrzejewski-Szmek
The mount fails, even though CAP_SYS_ADMIN is granted. Only file systems with FU_USERNS_MOUNT in .fs_flags may be mounted in userns, and the patch to add that fusectl was rejected [1]. It would be nice if we could check if the kernel has FU_USERNS_MOUNT for a given fs type, since this could change over time, but this information doesn't seem to be exported. So let's just skip this mount in userns to avoid an error during boot. [1] https://patchwork.kernel.org/patch/2828269/
2016-11-11tree-wide: make invocations of extract_first_word more uniform (#4627)Zbigniew Jędrzejewski-Szmek

2016-11-11timesyncd: clear ADJ_MAXERROR to keep STA_UNSYNC cleared after jump adjust ↵akochetkov
(#4626) NTP use jump adjust if system has incorrect time read from RTC during boot. It is desireble to update RTC time as soon as NTP set correct system time. Sometimes kernel failed to update RTC due to STA_UNSYNC get set before RTC update finised. In that case RTC time wouldn't be updated within long time. The commit makes RTC updates stable. When NTP do jump time adjust using ADJ_SETOFFSET it clears STA_UNSYNC flag. If don't clear ADJ_MAXERROR, STA_UNSYNC will be set again by kernel within 1 second (by second_overflow() function). STA_UNSYNC flag prevent RTC updates in kernel. Sometimes the kernel is able to update RTC withing 1 second, but sometimes it falied.
2016-11-11build-sys: use lowercase consistently in AS_HELP_STRINGMichael Biebl
We were using a mix of upper and lowercase. Since autoconf's own help output uses lowercase, use that as well.
2016-11-11basic/virt: fix userns check on CONFIG_USER_NS=n kernel (#4651)Zbigniew Jędrzejewski-Szmek
ENOENT should be treated as "false", but because of the broken errno check it was treated as an error. So ConditionVirtualization=user-namespaces probably returned the correct answer, but only by accident. Fixes #4608.

2016-11-11fstab-generator: add x-systemd.mount-timeout (#4603)Christian Hesse
This adds a new systemd fstab option x-systemd.mount-timeout. The option adds a timeout value that specifies how long systemd waits for the mount command to finish. It allows to mount huge btrfs volumes without issues. This is equivalent to adding option TimeoutSec= to [Mount] section in a mount unit file. fixes #4055

2016-11-09busctl introspect: accept direction="out" for signalsMantas Mikulėnas
According to the D-Bus spec (v0.29), | The direction element on <arg> may be omitted, in which case it | defaults to "in" for method calls and "out" for signals. Signals only | allow "out" so while direction may be specified, it's pointless. Therefore we still should accept a 'direction' attribute, even if it's useless in reality. Closes: #4616
2016-11-08nspawn: fix condition for mounting resolv.conf (#4622)Christian Hesse
The file /usr/lib/systemd/resolv.conf can be stale, it does not tell us whether or not systemd-resolved is running or not. So check for /run/systemd/resolve/resolv.conf as well, which is created at runtime and hence is a better indication.
2016-11-08core: on DynamicUser= make sure that protecting sensitive paths is enforced ↵Djalal Harouni
(#4596) This adds a variable that is always set to false to make sure that protect paths inside sandbox are always enforced and not ignored. The only case when it is set to true is on DynamicUser=no and RootDirectory=/chroot is set. This allows users to use more our sandbox features inside RootDirectory= The only exception is ProtectSystem=full|strict and when DynamicUser=yes is implied. Currently RootDirectory= is not fully compatible with these due to two reasons: * /chroot/usr|etc has to be present on ProtectSystem=full * /chroot// has to be a mount point on ProtectSystem=strict.
