because it is missing
After all, we want to be able to boot with /etc empty one day...
|
|
This undoes part of commit e6a4a517befe559adf6d1dbbadf425c3538849c9.
Instead of removing the error message about non-empty journal bind mount
directories, simply downgrade the message to a warning and proceed.

Only accept cpu quota values in percentages, get rid of period
definition.
It's not clear whether the CFS period controllable per-cgroup even has a
future in the kernel, hence let's simplify all this, hardcode the period
to 100ms and only accept percentage based quota values.

Currently if nspawn was called with --link-journal=host or
--link-journal=auto and the right /var/log/journal/machine-id/ exists
then the bind mount the subdirectory into the container might fail due
to the ~/mycontainer/var/log/journal/machine-id/ of the container not
being empty.
There is no reason to check if the container journal subdir is empty
since there will be a bind mount on top of it. The user asked for a bind
mount so give it.
Note: a next call with --link-journal=guest may fail due to the
/var/log/journal/machine-id/ on the host not being empty.

This is the behaviour the kernel cgroup rework exposes for all
controllers, hence let's do this already now for all cases.
|
|
Introduce a (unsigned long) -1 as "unset" state for cpu shares/block io
weights, and keep the startup unit set around all the time.
|
|
Similar to CPUShares= and BlockIOWeight= respectively. However only
assign the specified weight during startup. Each control group
attribute is re-assigned as weight by CPUShares=weight and
BlockIOWeight=weight after startup. If not CPUShares= or
BlockIOWeight= be specified, then the attribute is re-assigned to each
default attribute value. (default cpu.shares=1024, blkio.weight=1000)
If only CPUShares=weight or BlockIOWeight=weight be specified, then
that implies StartupCPUShares=weight and StartupBlockIOWeight=weight.

This fallback will anyway never get tested, so rip it out.

We shouldn't destroy IPC objects of system users on logout.
http://lists.freedesktop.org/archives/systemd-devel/2014-April/018373.html
This introduces SYSTEM_UID_MAX defined to the maximum UID of system
users. This value is determined compile-time, either as configure switch
or from /etc/login.defs. (We don't read that file at runtime, since this
is really a choice for a system builder, not the end user.)
While we are at it we then also update journald to use SYSTEM_UID_MAX
when we decide whether to split out log data for a specific client.
|
|
|
|
Use helper functions, and add some more sanity checking/asserts.
|
|
Similar to the previous patch, exchange a length and a pointer with only one offset variable.
Also fix the type of the options to be uint8_t[], rather than uint8_t*.
|
|
Store a pointer to the options in the DHCPMessage struct, and pass
this together with an offset around, rather than a uint8_t**.
This avoids us having to (re)compute the pointer; and changes
dhcp_option_append from adjusting both the pointer to the next
option and the remaining size of the options, to just adjusting
the current offset.
This makes the code a bit simpler to follow IMHO, but there should
be no functional change.

boot using this
This is useful to make sure the system clock stays monotonic even on
systems that lack an RTC.
Also, why we are at it, also use the systemd release time for bumping
the clock, since it's a slightly less bad than starting with jan 1st,
1970.
This also moves timesyncd into the early bootphase, in order to make
sure this initial bump is guaranteed to have finished by the time we
start real daemons which might write to the file systemd and thus
shouldn't leave 1970's timestamps all over the place...

If the udev queue is empty and "/run/udev/queue" does not exist,
"udevadm settle" would return with EXIT_FAILURE, because the inotify on
"/run/udev/queue" would fail with ENOENT.
This patch lets "udevadm settle" exit with EXIT_SUCCESS in this case.

This patch introduces sit tunnel support to networkd
Example conf:
file: sit.netdev
[NetDev]
Name=sit-tun
Kind=sit
MTUBytes=1480
[Tunnel]
Local=10.65.223.238
Remote=10.65.223.239
file: sit.network
[Match]
Name=em1
[Network]
Tunnel=sit-tun
[tomegun: rebased]

For now, we accept both link-local and routable addresses, maybe we want to
restrict ourselves to routable addresses only.
|
|
Expose states 'degraded' or 'routable' if a link has a site/link-local or a routable address, respectively.
|
|
|
|
|
|
|
|
Also remove the equivalent functionality from networkd.

When we dropped support for creating a per-user to the "main" X11
display we stopped returning useful data in the "Display" user property.
With this change this is fixed and we again expose an appropriate
(graphical session) in the property that is useful as the "main" one, if
one is needed.

This makes "systemd-analyze plot" read host information from remote.
While we are it show if this is a virtualized system.
