Some places invoked fflush() directly with their own manual error
checking, let's unify all that by using fflush_and_check().
This also unifies the general error paths of fflush()+rename() file
writers.

If some interfaces are given on the commandline, ignore all others.

This patch add support for vxlan VXLAN Group Policy Option.
https://tools.ietf.org/html/draft-smith-vxlan-group-policy-00
http://lwn.net/Articles/628683/

We must consider 'pending' links as if they may be managed by networkd, as this
is the state we enter before deciding wether networkd should manage the link
or not, so we better wait for this decision being made.

networkd: add support for Macvtap
|
|
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.

-i (aka --interface) takes an argument. Tell getopt_long() that, so that optarg
isn't NULL.

|
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 patch adds support for setting the

Add Pv6 Flow Label support. The 20-bit Flow Label field in the IPv6

This patch adds support to configure IFF_VNET_HDR flag

property callback returns are consistent
|
|
It is no different to return 0 over 1 in the property
callback. It is confusing to return 1 which made me think
1 has a special purpose. This way code is consistent with
the rest of the tree.

Merge write_string_file(), write_string_file_no_create() and
write_string_file_atomic() into write_string_file() and provide a flags mask
that allows combinations of atomic writing, newline appending and automatic
file creation. Change all users accordingly.

- 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

networkd: be more defensive when writing to ipv4/ipv6 forwarding sett…
|
|
1) never bother with setting the flag for loopback devices
2) if we fail to write the flag due to EROFS (which is likely to happen
in containers where /proc/sys is read-only) or any other error, check
if the flag already has the right value. If so, don't complain.
Closes #469

Ipv6 private extensions
|
|
This patch add support for ipv6 privacy extensions.
The variable /proc/sys/net/ipv6/conf/<if>/use_tempaddr
can be changed via the boolean
IPv6PrivacyExtensions=[yes/no/prefer-temporary]
When true enables privacy extensions, but prefer public addresses over
temporary addresses.
prefer-temporary prefers temporary adresses over public addresses.
Defaults to false.
[Match]
Name=enp0s25
[Network]
IPv6PrivacyExtensions=prefer-temporary
|
|
Error message for enumerating addresses was not 'addresses' but 'links'.
This patch fixes it.
|
|
If a link is attempted t obe enslaved by a netdev that has already failed, we
must fail immediately and not save the callback for later, as it will then
never get triggered.
|
|
This only happens when something has gone wrong, so is not easy to hit. However,
if a bridge (say) is configured on a system without bridge support we will hit
this.
Fixes issue #299.

The kernel bonding layer allows passing an array of ARP IP targets as
bond-configuration. Due to the weird implementation of arrays in netlink
(which we haven't figure out a generic way to support, yet), we usually
hard-code the supported array-sizes. However, this should not be exported
from sd-netlink.
Instead, make sure the caller just uses it's current hack of enumerating
the types, and the sd-netlink core will have it's own list of supported
array-sizes (to be removed in future extensions, btw!). If either does not
match, we will just return a normal error.
Note that we provide 2 constants for ARP_IP_TARGETS_MAX now. However, both
have very different reasons:
- the constant in netdev-bond.c is used to warn the user that the given
number of targets might not be supported by the kernel (even though the
kernel might increase that number at _any_ time)
- the constant in sd-netlink is solely used due to us missing a proper
array implementation. Once that's supported in the type-system, it can
be removed without notice
Last but not least, this patch turns the log_error() into a log_warning().
Given that the previous condition was off-by-one, anyway, it never hit at
the right time. Thus, it was probably of no real use.

Replaces strerror() usage with log_netdev_error_errno()
|
|
This ports a lot of manual code over to sigprocmask_many() and friends.
Also, we now consistly check for sigprocmask() failures with
assert_se(), since the call cannot realistically fail unless there's a
programming error.
Also encloses a few sd_event_add_signal() calls with (void) when we
ignore the return values for it knowingly.

The names fw-util.[ch] are too ambiguous, better rename the files to
firewall-util.[ch]. Also rename the test accordingly.
|
|
Improve tun/tap logging by using the new log_*errno*() functions that set 'errno' explicitly. Also fix a bunch of incorrect errno/r confusions.

IPForwarding=kernel v3
|
|
In 5a8bcb674f71a20e95df55319b34c556638378ce, IPForwarding was introduced
to set forwarding flags on interfaces in .network files. networkd sets
forwarding options regardless of the previous setting, even if it was
set by e.g. sysctl. This commit creates a new option for IPForwarding,
"kernel", that preserves the sysctl settings rather than always setting
them.
See https://bugs.freedesktop.org/show_bug.cgi?id=89509 for the initial
bug report.
