2015-07-27networkd: capitalize VNetHeader= as VnetHeader=Lennart Poettering
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.
2015-07-26networkd-wait-online: fix -i argumentMartin Pitt
-i (aka --interface) takes an argument. Tell getopt_long() that, so that optarg isn't NULL.
2015-07-24networkd: rename RootBlock to AllowPortToBeRootZbigniew Jędrzejewski-Szmek
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.
2015-07-24networkd: turn UnicastFlood on by defaultZbigniew Jędrzejewski-Szmek
Looking at the kernel commit, "on" seems to be the default value: commit 867a59436fc35593ae0e0efcd56cc6d2f8506586 Author: Vlad Yasevich <vyasevic@redhat.com> Date: Wed Jun 5 10:08:01 2013 -0400 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.
2015-07-24networkd: rename BPDUGuard to UseBPDUZbigniew Jędrzejewski-Szmek
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).
2015-07-24network: rename DiffServiceCodePoint to CopyDSCPZbigniew Jędrzejewski-Szmek
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.

property callback returns are consistent
2015-07-08property callback returns are consistentUmut Tezduyar Lindskog
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.

2015-07-06networkd: various fixes for the IPv6 privacy extensions supportLennart Poettering
- 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

2015-07-06networkd: be more defensive when writing to ipv4/ipv6 forwarding settingsLennart Poettering
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

2015-07-05networkd: Add support for ipv6 privacy extensionSusant Sahani
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.
2015-06-29networkd: netdev - avoid hanging transactions in failure casesTom Gundersen
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.
2015-06-29networkd: fix segfault when cancelling callbacksTom Gundersen
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.
2015-06-24sd-netlink: don't export internal type-system detailsDavid Herrmann
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.

2015-06-15everywhere: port everything to sigprocmask_many() and friendsLennart Poettering
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.

2015-06-11networkd: create "kernel" setting for IPForwardingNick Owens
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.
