Even when we use shortened, combined words, we still should uppercase
where a new word starts. I couldn't find a canonically capitalized
version of this term, hence I think we should follow our naming rules
here.
This should clear up some confusion in
https://github.com/systemd/systemd/issues/717.
This basically copies the description from systemd.unit to this
man page. Masking can happen also in /run, so strike the part
about /etc, and also add the magic work "mask".
Justification is similar to BPDUGuard rename. "Positive" values
are easier. This is a rather uncommon option, so using a slightly
longer name should not be a problem, and may in fact may make it
easier to guess what the option does without reading the
documentation.
Looking at the kernel commit, "on" seems to be the default value:

bridge: Add a flag to control unicast packet flood.
Add a flag to control flood of unicast traffic. By default, flood is
on and the bridge will flood unicast traffic if it doesn't know
the destination. When the flag is turned off, unicast traffic
without an FDB will not be forwarded to the specified port.
... and it seems to be the reasonable thing to do by default.
Rename to follow the follow the style of other options.
In general "positive" options are preferred to "negative" ones,
because they are easier to describe and easier for humans to
parse (c.f. the shortening on the man page entry).
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.
