2015-06-02networkd: 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.
2015-05-30networkctl: fix uninitialized variableRonny Chevalier
We ignore the return value of sd_device_get_devtype, then devtype could be uninitialized when used with streq_ptr. So we need to initialize it first.

No functional changes.
2015-05-25networkd: fix IFF_UP when ipv6 support is disabledTom Gundersen
Passing ipv6 options (even when they should be noops) caused IFF_UP to fail when ipv6 was supported. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=90103

2015-05-15networkd: don't touch global forwarding settingBenedikt Morbach
This reverts commit 43c6d5abacaebf813845934ec8d5e5ee3c431854 (and a small part of 4046d8361c55c80ab8577aea52523b9e6eab0d0c) 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.

2015-05-12networkd: network_get - allow udev_device to be NULLTom Gundersen
In containers we never have udev devices, so drop the assert. This fixes an assertion introduced in af3aa302741b6edb0729925febb5f8bc26721fe3.
2015-05-11core,network: major per-object logging reworkLennart Poettering
This changes log_unit_info() (and friends) to take a real Unit* object insted of just a unit name as parameter. The call will now prefix all logged messages with the unit name, thus allowing the unit name to be dropped from the various passed romat strings, simplifying invocations drastically, and unifying log output across messages. Also, UNIT= vs. USER_UNIT= is now derived from the Manager object attached to the Unit object, instead of getpid(). This has the benefit of correcting the field for --test runs. Also contains a couple of other logging improvements: - Drops a couple of strerror() invocations in favour of using %m. - Not only .mount units now warn if a symlinks exist for the mount point already, .automount units do that too, now. - A few invocations of log_struct() that didn't actually pass any additional structured data have been replaced by simpler invocations of log_unit_info() and friends. - For structured data a new LOG_UNIT_MESSAGE() macro has been added, that works like LOG_MESSAGE() but prefixes the message with the unit name. Similar, there's now LOG_LINK_MESSAGE() and LOG_NETDEV_MESSAGE(). - For structured data new LOG_UNIT_ID(), LOG_LINK_INTERFACE(), LOG_NETDEV_INTERFACE() macros have been added that generate the necessary per object fields. The old log_unit_struct() call has been removed in favour of these new macros used in raw log_struct() invocations. In addition to removing one more function call this allows generated structured log messages that contain two object fields, as necessary for example for network interfaces that are joined into another network interface, and whose messages shall be indexed by both. - The LOG_ERRNO() macro has been removed, in favour of log_struct_errno(). The latter has the benefit of ensuring that %m in format strings is properly resolved to the specified error number. - A number of logging messages have been converted to use log_unit_info() instead of log_info() - The client code in sysv-generator no longer #includes core code from src/core/. - log_unit_full_errno() has been removed, log_unit_full() instead takes an errno now, too. - log_unit_info(), log_link_info(), log_netdev_info() and friends, now avoid double evaluation of their parameters
2015-05-04network: Implement fallback DHCPv6 prefix handling for older kernelsPatrik Flykt
When setting IPv6 addresses acquired by DHCPv6, systemd-networkd sets the IFA_F_NOPREFIXROUTE flag in the IFA_FLAGS netlink attribute. As the flag and the attribute are present starting with Linux 3.14, older kernels will need systemd-network to manage prefix route expiry. By default, DHCPv6 addresses are first assigned setting the IFA_F_NOPREFIXROUTE flag in the IFA_FLAGS netlink attribute. Should the address assignment fail, the same assignment is tried without the IFA_FLAGS attribute. Should also the second attempt fail, an error is printed and address assignment ends with failure. As successful use of the IFA_FLAGS netlink attribute is recorded in the Link structure, the DHCPv6 code will know if the kernel or systemd-network fallback code handles expiring prefixes. The prefix expiration and IPv6 address updating fallback code is resurrected from the parts deleted with commit 47d45d3cde45d6545367570264e4e3636bc9e345. This patch can be removed once the minimum kernel requirements are greater than or equal to 3.14.

2015-04-29networkd: tunnel improve loggingSusant Sahani
Replaces a lof ot strerror() usage with log_netdev_error_errno()
2015-04-29sd-bus: drop bus parameter from message callback prototypeLennart Poettering
This should simplify the prototype a bit. The bus parameter is redundant in most cases, and in the few where it matters it can be derived from the message via sd_bus_message_get_bus().
2015-04-21networkd-fdb: indentation/whitespace fixesLennart Poettering
2015-04-21networkd: improve how networkd logs thingsLennart Poettering
This makes adds a couple of fixes: - Introduces log_netdev_error_errno() and friends, which takes an error number, and matches what log_link_error_errno() and friends do. - Replaces a lof ot strerror() usage with log_netdev_error_errno(), log_link_error_errno() and log_erro_errno() - Uppercases the first character of many log messages, after all this is supposed to be english language - Drops manual negating of error codes before passing them to log functions, the log functions all do that internally anyway. Some other minor fixes. Behaviour should not change really.

2015-04-21networkd: fix confusion between log_netdev_error() but log_warning_netdev()Lennart Poettering
We should always name the object first, the level second, like everywhere else in the sources.

2015-03-27networkd-dhcp6: Do not handle prefix expiryPatrik Flykt
Expiring prefixes need not be handled anymore as the kernel has been instructed not to create routes for DHCPv6 assigned addresses via the IFA_F_NOPREFIXROUTE flag.
2015-03-27systemd-networkd: Use IFA_F_NOPREFIXROUTE with IPv6 addressesPatrik Flykt
The IFA_F_NOPREFIXROUTE flag prevents the kernel from creating new onlink prefixes when a DHCPv6 IPv6 address with a prefix length is set from user space. IPv6 routing will follow the onlink status from Router Advertisment Prefix Information options or any manually set route, which is the correct thing to do. As this flag has a larger value than what fits into an unsigned char, update the flag attribute to an uint32_t and set it with an IFA_FLAGS attribute when writing netlink messages to the kernel.
2015-03-21networkd: use LOG_WARN not LOG_ERR for non-fatal errorsZbigniew Jędrzejewski-Szmek
2015-03-15network: add UseNTP DHCP optionMichael Marineau
Despite having the internal logic in place to enable/disable using NTP servers provided by DHCP the network config didn't expose the option.
2015-03-13Use space after a silencing (void)Zbigniew Jędrzejewski-Szmek
We were using a space more often than not, and this way is codified in CODING_STYLE.
2015-03-07networkctl: avoid leak if a field was specified twiceZbigniew Jędrzejewski-Szmek
The input data would have to be borked, so this is unlikely to happen, but since we have a nice helper function to do it properly... why not? CID #1261390.
2015-03-04networkd: Make DHCP client ID creation configurableJan Janssen
2015-03-04networkd: netdev - inform when we take over an existing netdevTom Gundersen
The crucial point here is that we will not change the settings of a netdev created by someone else we simply use it as is and trust it was set up as intended. This is confusing in the case of the pre-created netdev's (bond0 etc.), the solution should probably be to simply make the kernel stop creating these devices as they are pretty useless.
2015-02-27networkd: add support for Uplink Failure DetectionAlin Rauta
Introduce BindCarrier= to indicate the set of links that determine if the current link should be brought UP or DOWN. [tomegun: add a bit to commit message]
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-14networkd: network - rename ipv6token parserTom Gundersen
Too generic name.
2015-02-14networkd: .network - rename LinkLocal to LinkLocalAddressingTom Gundersen
Makes it a bit less ambiguous.
2015-02-12networkd: explicitly enable/disable ipv6ll addressesTom Gundersen
The kernel does not like getting an empty container, so just always pass the parameter, even if it is the default.
2015-02-11networkd: fdb - fix const warningTom Gundersen
2015-02-11networkd: don't do exit-on-idle if there is something wrong with the dbus ↵Tom Gundersen
connection Just fall back to plain old event loop in this (highly unlikely) case. In the glorious future when kdbus is upstream we can of course drop all this.

From: Paul Martin <paul.martin@codethink.co.uk> Date: Wed, 11 Feb 2015 11:47:16 +0000 Subject: [PATCH] networkd dhcpv4 logging endian fix On a big-endian host, systemd-networkd prints out IPv4 network addresses byte reversed: Feb 10 16:43:32 hostname systemd-networkd[151]: eth0 : DHCPv4 address 158.1.24.10/16 via 1.1.24.10 The address obtained is 10.24.1.158/16 and the route is 10.24.0.0/16 dev eth0 src 10.24.1.187 The macro ADDRESS_FMT_VAL() unpacks a "struct in_addr" in a little-endian specific manner. This patch forces the passed address into host order, then unpacks it. On an x86 later than i486, compiled with -O2, the only extra overhead is a single bswap instruction.
