Old name was slightly misleading, because this flag does not determine
whether DSCP is used overall, but only if it is copied to the
decapsulated packet. Rename to better reflect that.
"Copy" does not imply direction. This is on purpose, because we might
later on enhance the setting to allow/disallow copying in the other
direction, to the encapsulated packet. If that is implemented,
CopyDSCP could understand additional values. This is nicer than
having two separate settings and follows the example of DHCP=.
Also, we try to avoid abbreviations, but we allow acronyms
like MTU, in DiscoverPathMTU=.
This setting was recently added, so it's fine to rename it without
backwards compat.
This scheme fixes permalinks to distinguish between items that would previously have the same ID attribute.
Where possible the generated ID values are the same as those generated with the previous versions of the stylesheet
to retain backwards compatibility with published links.
As a side effect of the changes xsltproc should no longer complain about duplicate IDs during build.
Given a container "foo", that maps user id $UID to container user, using
user namespaces, this NSS module extenstion will now map the $UID to a
name "vu-foo-$TUID" for the translated UID $UID.
Similar, userns groups are mapped to "vg-foo-$TGID" for translated GIDs
of $GID.
This simple change should make userns users more discoverable. Also,
given that many tools like "adduser" check NSS before allocating a UID,
should lower the chance of UID range conflicts between tools.
- Make sure that the IPv6PrivacyExtensions=yes results in
prefer-temporary, not prefer-public.
- Introduce special enum value "kernel" to leave setting unset, similar
how we have it for the IP forwarding settings.
- Bring the enum values in sync with the the strings we parse for them,
to the level this makes sense (specifically, rename "disabled" to
"no", and "prefer-temporary" to "yes").
- Make sure we really set the value to to "no" by default, the way it is
already documented in the man page.
- Fix whitespace error.
- Make sure link_ipv6_privacy_extensions() actually returns the correct
enum type, rather than implicitly casting it to "bool".
- properly size formatting buffer for ipv6 sysctl value
- Don't complain if /proc/sys isn't writable
- Document that the enum follows the kernel's own values (0 = off, 1 =
prefer-public, 2 = prefer-temporary)
- Drop redundant negating of error code passed to log_syntax()
- Manpage fixes
This fixes a number of issues from PR #417
We refer to the same sysctl-setting twice, which is misleading. Correctly
list all global forwarding options. As we _always_ change the forwarding
setting on links, they will get disabled by default. The global sysctl
defaults thus will not have any effect.
This did not really work out as we had hoped. Trying to do this upstream
introduced several problems that probably makes it better suited as a
downstream patch after all. At any rate, it is not releaseable in the
current state, so we at least need to revert this before the release.
* by adjusting the path to binaries, but not do the same thing to the
search path we end up with inconsistent man-pages. Adjusting the search
path too would be quite messy, and it is not at all obvious that this is
worth the effort, but at any rate it would have to be done before we
could ship this.
* this means that distributed man-pages does not make sense as they depend
on config options, and for better or worse we are still distributing
man pages, so that is something that definitely needs sorting out before
we could ship with this patch.
* we have long held that split-usr is only minimally supported in order
to boot, and something we hope will eventually go away. So before we start
adding even more magic/effort in order to make this work nicely, we should
probably question if it makes sense at all.
./configure --enable/disable-kdbus can be used to set the default
behavior regarding kdbus.
If no kdbus kernel support is available, dbus-dameon will be used.
With --enable-kdbus, the kernel command line option "kdbus=0" can
be used to disable kdbus.
With --disable-kdbus, the kernel command line option "kdbus=1" is
required to enable kdbus support.
This adds man-pages for most of the libudev symbols we export. Similar
symbols are grouped together in a single man-page, with respective links
added. All man-pages contain the full skeleton including NAME, SYNOPSIS,
RETURN VALUE and SEE ALSO. However, most of them still lack the
DESCRIPTION part. This should be copied from the gtkdoc descriptions in
src/libudev/libudev*.[ch]. Any help is welcome! (the whole skeleton is
already done, so it's really just about the prose-part of the man-pages to
be written).
Missing from the man-pages are the following parts:
- udev_set_log_fn()
- udev_[gs]et_log_priority()
- udev_[gs]et_userdata()
- udev_list_entry_foreach()
- udev_device_get_seqnum()
- udev_device_get_usec_since_initialized()
- udev_util_encode_string()
These are considered legacy, afaik. If not, please feel free to add them
now!
Furthermore, udev-hwdb and udev-queue are not documented at all (for the
same reasons).
We do not support '/run' for hwdb files. Drop it from the man-pages so
people don't accidentally use it.

Improve the documentation of bus credentials by mentioning send-time metadata. This needs more love, we should really clarify metadata details here. However, this is still better than nothing, so it's fine.
Two of the bits in the MAC address are set unconditioanlly, and the rest is randomized,
make this clear in the documentation (as it currently read as if it was all random).
If the EDITOR environment variable is not set, the Debian policy
recommends to use the /usr/bin/editor program as default editor.
This file is managed via the dpkg alternatives mechanism and typically
used in Debian/Ubuntu and derivatives to configure the default editor.
See section 11.4 of the Debian policy [1].
Therefor prefer /usr/bin/editor over specific editors if available.

Export the MOUNT_PATH and UMOUNT_PATH variables as XML entities and use them in
the systemctl.1 manpage instead of hardcoding the path in /usr/bin.
Tested:
- Ran ./configure ac_cv_path_MOUNT_PATH=/bin/mount (same for umount) and
rebuilt the manpages, confirmed that the correct path was in man/systemctl.1
- Rebuilt man/systemd.directives.xml and the man pages derived from it,
confirmed that the correct paths were there as well.
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions
like Debian which still have not adopted a /usr merge setup.
Use XML entities from man/custom-entities.ent to replace configured paths while
doing XSLT processing of the original XML files. There was precedent of some
files (such as systemd.generator.xml) which were already using this approach.
This addresses most of the (manual) fixes from this patch:
http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220
The idea of using generic XML entities was presented here:
http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html
This patch solves almost all the issues, with the exception of:
- Path to /bin/mount and /bin/umount.
- Generic statements about preference of /lib over /etc.
These will be handled separately by follow up patches.
Tested:
- With default configure settings, ran "make install" to two separate
directories and compared the output to confirm they matched exactly.
- Used a set of configure flags including $CONFFLAGS from Debian:
http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules
Installed the tree and confirmed the paths use /lib/systemd instead of
/usr/lib/systemd and that no other unexpected differences exist.
- Confirmed that `make distcheck` still passes.
This patch simplify swapon usage in systemd. The command swapon(8)
since util-linux v2.26 supports "-o <list>". The idea is exactly the
same like for mount(8). The -o specifies options in fstab-compatible
way. For systemd it means that it does not have to care about things
like "discard" or another swapon specific options.
swapon -o <options-from-fstab>
For backward compatibility the code cares about "Priority:" swap unit
field (for a case when Priority: is set, but pri= in the Options: is
missing).

The hostname(1) tool allows comments in /etc/hostname. Introduce a new
read_hostname_config() in hostname-util which reads a hostname configuration
file like /etc/hostname, strips out comments, whitespace, and cleans the
hostname. Use it in hostname-setup.c and hostnamed and remove duplicated code.
Update hostname manpage. Add tests.

Currently we have no way how to specify dependencies between fstab
entries (or another units) in the /etc/fstab. It means that users are
forced to bypass fstab and write .mount units manually.
The patch introduces new systemd fstab options:
x-systemd.requires=<PATH>
- to specify dependence an another mount (PATH is translated to unit name)
x-systemd.requires=<UNIT>
- to specify dependence on arbitrary UNIT
x-systemd.requires-mounts-for=<PATH ...>
- to specify dependence on another paths, implemented by
RequiresMountsFor=. The option may be specified more than once.
For example two bind mounts where B depends on A:
/mnt/test/A /mnt/test/A none bind,defaults
/mnt/test/A /mnt/test/B none bind,x-systemd.requires=/mnt/test/A
More complex example with overlay FS where one mount point depends on
"low" and "upper" directories:
/dev/sdc1 /mnt/low ext4 defaults
/dev/sdc2 /mnt/high ext4 defaults
overlay /mnt/merged overlay lowerdir=/mnt/low,upperdir=/mnt/high/data,workdir=/mnt/high/work,x-systemd.requires-mounts-for=/mnt/low,x-systemd.requires-mounts-for=mnt/high

This reverts commit 43c6d5abac
(and a small part of 4046d8361c)
It turns out we don't actually need to set the global ip_forward setting.
The only relevant setting is the one on each interface.
What the global toggle actually does is switch forwarding on/off for all
currently present interfaces and change the default for new ones.
That means that by setting the global ip_forward we
- Introduce a race condition, because if the interface with IPForward=yes
is brought up after one with IPForward=no, both will have forwarding
enabled, because the global switch turns it on for all interfaces.
If the other interface comes up first networkd correctly sets forward=0
and it doesn't get overridden.
- Change the forwarding setting for interfaces that networkd is not
configured to touch, even if the user disabled forwarding via sysctl,
either globally or per-interface
As forwarding works fine without this, as long as all relevant interfacest
individually set IPForward=yes: just drop it
This means that non-networkd interfaces use the global default while
networkd interfaces default to off if IPForward isn't given.
Previously all bind mount mounts were applied in the order specified,
followed by all tmpfs mounts in the order specified. This is
problematic, if bind mounts shall be placed within tmpfs mounts.
This patch hence reworks the custom mount point logic, and alwas applies
them in strict prefix-first order. This means the order of mounts
specified on the command line becomes irrelevant, the right operation
will always be executed.
While we are at it this commit also adds native support for overlayfs
mounts, as supported by recent kernels.
Previously, the man page suggested to only use nspawn for testing,
building, and debugging things. However, it is nowadays used in
production and used as building block for rocket, hence let's just admit
that it's pretty much production ready.
Some distributions (such as Fedora) are using the VARIANT field to
indicate to select packages which of several default configurations
they should be using. For example, VARIANT=Server provides a
different default firewall configuration (blocking basically
everything but SSH and the management console) whereas
VARIANT=Workstation opens many other ports for application
compatibility.
By adding this patch to the manual pages, we can standardize on a
cross-distribution mechanism for accomplishing this.

This introduces /run/systemd/fsck.progress as a simply
AF_UNIX/SOCK_STREAM socket. If it exists and is connectable we'll
connect fsck's -c switch with it. If external programs want to get
progress data they should hence listen on this socket and will get
all they need via that socket. To get information about the connecting
fsck client they should use SO_PEERCRED.
Unless /run/systemd/fsck.progress is around and connectable this change
reverts back to v219 behaviour where we'd forward fsck output to
/dev/console on our own.
Not that all functionality has been ported over to logind, the old
implementation can be removed. There goes one of the oldest parts of
the systemd code base.
The original idea of systemd.pc was to contain arch-independent system
and systemd information. By exposing libdir as part of the fields (added
in eb39a6239c), it started to carry
arch-dependent data, thus breaking multilib systems. It was then moved
to pkgconfiglibdir to deal with this (in
aec432c613), but actually the right
approach is to simply not include libdir in the .pc file at all.
THis patch hence more or less reverts both commits again, and moves the
.pc file back into pkgconfigdatadir.
As alternative for querying the systems primary libdir there's now
"systemd-path system-library-arch", hence a more correct alternative
exists for querying this variable from the .pc file.

Generally, we will not follow symlinks, except for "w".
Avoid documentation for now for fifo, device node, directory lines,
which currently follow symlinks but better shouldn't.
"the name it is" is clumsy english, and since the most recently referred
to thing was a name anyway we can just leave the "it is".
This matches later uses in the same document.
systemd-timesyncd not only does NTP, but also manages clock monotonicity
using a flags file. In future, it might learn PTP support. Hence don't
expose its enablement state as "NTP" but use the more generic term
"network time synchronization". After all, for similar reasons
systemd-timesyncd is not called systemd-ntpd.
