Lennart Poettering 98bf5011fe sysctl: when failing to process a config line, show line nr 2016-11-02 11:29:59 -06:00
Lennart Poettering 9c37b41c61 sysctl: split out condition check into its own function 
This way, we can get rid of a label/goto.

Lennart Poettering 39540de8ab sysctl: do not fail systemd-sysctl.service if /proc/sys is mounted read-only 
Let's make missing write access to /proc/sys non-fatal to the sysctl service.

This is a follow-up to 411e869f49 which altered
the condition for running the sysctl service to check for /proc/sys/net being
writable, accepting that /proc/sys might be read-only. In order to ensure the
boot-up stays clean in containers lower the log level for the EROFS errors
generated due to this.

Lennart Poettering a581e45ae8 unit: unify some code with new unit_new_for_name() call 2016-11-02 11:29:59 -06:00
Lennart Poettering 11222d0fe0 core: make the root mount perpetual too 
Now that have a proper concept of "perpetual" units, let's make the root mount
one too, since it also cannot go away.

Lennart Poettering f5869324e3 core: rework the "no_gc" unit flag to become a more generic "perpetual" flag 
So far "no_gc" was set on -.slice and init.scope, to units that are always
running, cannot be stopped and never exist in an "inactive" state. Since these
units are the only users of this flag, let's remodel it and rename it
"perpetual" and let's derive more funcitonality off it. Specifically, refuse
enqueing stop jobs for these units, and report that they are "unstoppable" in
the CanStop bus property.

Zbigniew Jędrzejewski-Szmek 0809d7740c condition: simplify condition_test_virtualization 
Rewrite the function to be slightly simpler. In particular, if a specific
match is found (like ConditionVirtualization=yes), simply return an answer
immediately, instead of relying that "yes" will not be matched by any of
the virtualization names below.

No functional change.

Zbigniew Jędrzejewski-Szmek 299a34c11a detect-virt: add --private-users switch to check if a userns is active 
Various things don't work when we're running in a user namespace, but it's
pretty hard to reliably detect if that is true.

A function is added which looks at /proc/self/uid_map and returns false
if the default "0 0 UINT32_MAX" is found, and true if it finds anything else.
This misses the case where an 1:1 mapping with the full range was used, but
I don't know how to distinguish this case.

'systemd-detect-virt --private-users' is very similar to
'systemd-detect-virt --chroot', but we check for a user namespace instead.

Susant Sahani 5325382440 networkd : verify dns ip address when parsing configuration (#4492) 
Invalid IP addresses would be passed through as-is:
$ networkctl status wlp3s0:

       Link File: /usr/lib/systemd/network/99-default.link
    Network File: /etc/systemd/network/wlp3s0.network

           State: routable (configured)
            Path: pci-0000:03:00.0
          Driver: iwlwifi
          Vendor: Intel Corporation
           Model: Centrino Advanced-N 6205 [Taylor Peak] (Centrino Advanced-N 6205 AGN)
      HW Address: XXXXXXXXXX (Intel Corporate)
         Address: 192.168.2.103
                  XXXXXXXXXXX
         Gateway: 192.168.2.1 (Arcadyan Technology Corporation)
             DNS: 127.0.0.5553

Instead verify that DNS= has a valid list of addresses when parsing configuration.

Fixes #4462.

Dongsu Park 6086d2daf3 test: skip exec tests when inaccessible dir is unavailable 
In case of running test-execute on systems with systemd < v232, several
tests like privatedevices or protectkernelmodules fail because
/run/systemd/inaccessible/ doesn't exist. In these cases, we should skip
tests to avoid unnecessary errors.
