2015-09-29util: introduce common version() implementation and use it everywhereLennart Poettering
This also allows us to drop build.h from a ton of files, hence do so. Since we touched the #includes of those files, let's order them properly according to CODING_STYLE.
2015-09-24networkd: Be opportunistic when declaring link configuredPatrik Flykt
The DHCP variable in the [Network] section of the network configuration file moves the link to the configured state according to the following: DHCP=yes Link is configured when either DHCPv4 or DHCPv6 succeed DHCP=ipv4 Link is configured only when DHCPv4 succeeds DHCP=ipv6 Link is configured only when DHCPv6 succeeds DHCP=no Neither DHCPv4 or DHCPv6 is attempted Reported by Martin Pitt. Fixes https://github.com/systemd/systemd/issues/1368

DHCPv6 suspend fixes
2015-09-23networkd: Wait for DHCPv6 before announcing link configuredPatrik Flykt
Wait until DHCPv6 has acquired an address before announcing the link to be configured. Log the DHCPv6 lease lost event.
2015-09-23sd-dhcp6-client: Properly handle DHCPv6 client restart after resumePatrik Flykt
Whenever a Router Advertisement is received, dhcp6_configure() will be called. A Router Advertisment can also instruct DHCPv6 to start acquiring IPv6 addresses in manged mode, if it previously was handling only other information. As an Router Advertisment is also received after the DHCPv6 client has resumed from a suspend, fix the function not to assume DHCPv6 is currently running, but instead try to restart it. Handle sd_dhcp6_start() returning -EALREADY indicating that the DHCPv6 client was already running. Collect all client unrefs in one place to unclutter the error handling. Fixes https://github.com/systemd/systemd/issues/963
2015-09-23Set accept_ra to "2" if enabled in configGeorg Müller
This causes the kernel to accept router advertisments even if ip forwarding is enabled for this interface. This fixes #1340.

A variety of mostly unrelated fixes
2015-09-22cgtop: underline table headerLennart Poettering
Let's underline the header line of the table shown by cgtop, how it is customary for tables. In order to do this, let's introduce new ANSI underline macros, and clean up the existing ones as side effect.
2015-09-22sd-lldp: hide internal detailsDavid Herrmann
Currently, sd-lldp.h exports "UPDATE_INFO".. and defines it to a magic constant '10'. This is completely bogus, so fix it to follow our coding standards: - Prefix exported symbols by SD_LLDP_* - Define a separate event-enum for event types - Translate internal state to external event-types
2015-09-22sd-ipv4ll: fix namespacingDavid Herrmann
Prefix all exported constants with SD_IPV4LL_* to avoid namespacing conflicts.
2015-09-22sd-icmp6-nd: fix namespacingDavid Herrmann
Prefix all exported constants by SD_ICMP6_ND_* to avoid any namespacing conflicts.
2015-09-22sd-dhcp6: fix namespacingDavid Herrmann
Prefix all exported constants with SD_DHCP6_CLIENT_* to avoid any namespacing conflicts.
2015-09-22sd-dhcp: fix namespacingDavid Herrmann
Prefix all constants with SD_DHCP_CLIENT_* to avoid namespacing conflicts.
2015-09-18sd-ipv4acd: introduce new library split out from sd-ipv4llTom Gundersen
This splits the Address Conflict Detection out of the Link Local library so that we can reuse it for DHCP and static addresses in the future. Implements RFC5227.
2015-09-18sd-ipv4ll: rework callbacksTom Gundersen
Firstly, no longer distinguish between STOP and INIT states. Secondly, do not trigger STOP events when calls to sd_ipv4ll_*() fail. The caller is the one who would receive the event and will already know that the call to sd_ipv4ll_*() has failed, so it is redundant. STOP events will now only be triggered by calling sd_ipv4ll_stop() explicitly or by some internal error in the library triggered by receiving a packet or an expiring timeout (i.e., any error that would otherwise not be reported back to the consumer of the library). Lastly, follow CODING_STYLE and always return NULL on unref. Protect from objects being destroyed in callbacks accordingly.
2015-09-12networkd:add support to configure ipv6 acceprt raSusant Sahani
This patch support to configure the ipv6 acceprt ra option. for more information see http://www.tldp.org/HOWTO/Linux+IPv6-HOWTO/proc-sys-net-ipv6..html
2015-09-09tree-wide: drop {} from one-line if blocksLennart Poettering
Patch via coccinelle.
2015-09-09tree-wide: use coccinelle to patch a lot of code to use mfree()Lennart Poettering
This replaces this: free(p); p = NULL; by this: p = mfree(p); Change generated using coccinelle. Semantic patch is added to the sources.
2015-09-07basic: rework virtualization detection APILennart Poettering
Introduce a proper enum, and don't pass around string ids anymore. This simplifies things quite a bit, and makes virtualization detection more similar to architecture detection.
2015-09-04networkd: adjust error codes for nonexisting DHCP dataMartin Pitt
Commit 0339cd770 changed libsystemd-network's error code for missing DHCP lease data from ENOENT to ENODATA. Adjust networkd accordingly. This fixes interfaces being stuck in "degraded/configuring" mode forever. https://github.com/systemd/systemd/issues/1147

networkd: add support for tunnel encap limit
2015-08-31networkd: dhcp-server - allow configuration of the poolTom Gundersen
The constraints we place on the pool is that it is a contiguous sequence of addresses in the same subnet as the server address, not including the subnet nor broadcast addresses, but possibly including the server address itself. If the server address is included in the pool it is (obviously) reserved and not handed out to clients.
2015-08-31networkd: dhcp-server - default to manage the whole subnetTom Gundersen
Don't restrict yourselves to 32 leases, simply manage the whole subnet by default.
2015-08-31sd-dhcp-server: simplify pool creationTom Gundersen
Merge sd_dhcp_server_set_address() and sd_dhcp_server_set_lease_pool() into sd_dhcp_server_configure_pool() as the behavior of the two former depends on the order they are called in. The flexibility is not needed, so let's just do this in one call.
2015-08-31networkd: add support for tunnel encap limitSusant Sahani
The Tunnel Encapsulation Limit option specifies how many additional levels of encapsulation are permitted to be prepended to the packet
2015-08-30networkd: initialize tz to nullThomas Hindoe Paaboel Andersen
We may not set it before checking it for null.

2015-08-27networkd: make sure we remove udev fd from epoll *before* closing itLennart Poettering
Otherwise we'll try to remove an invalid fd from epoll all the time.
2015-08-27networkd: emit DNS/NTP/Timezone info via DHCP server by defaultLennart Poettering
If we have the data, emit it by default.
2015-08-27networkd: propagate DNS/NTP server from uplink to dhcp serverLennart Poettering
When handing out DHCP leases, try to propagate DNS/NTP server information from "uplink". The "uplink" is automatically determined as the network interface with the highest priority default route on it.
2015-08-27dhcp,network: support emitting DNS/NTP server information from DHCP serverLennart Poettering
For now, this is very simple and IP addresses have to be configured manually.
2015-08-27networkd: split up networkd.h into per-object header filesLennart Poettering
No functional changes, just moving definitions into separate header files.
2015-08-27networkd: port many log messages over to newer logging APILennart Poettering
Let's drop some strerror() invocations, and make use of the easier to use newer logging APIs.
2015-08-27networkd: properly reset transient hostname when we lose a DHCP leaseLennart Poettering
Previously we were setting the transient hostname again, rather than resetting it.
2015-08-27networkd: optionally push dhcp timezone into timedatedLennart Poettering

2015-08-27dhcp: NTP servers should be requested by networkd but not implicitly by sd-dhcpLennart Poettering
The library so far always requested the NTP servers. This might be unnecessary in some uses, hence let's move the request into networkd instead.
2015-08-26dhcp: keep lease save/load functions privateLennart Poettering
When we make sd-dhcp public one day we really should not make sd_dhcp_lease_save() and sd_dhcp_lease_load() public, since it's pretty much only useful as internal utility for networkd itself.
2015-08-26networkd: let's uppercase the first character in log messagesLennart Poettering
Let's try to generate log messages that resemble english language sentences, hence uppercase the first character.
2015-08-26dhcp,network: implement RFC 4833 (DHCP Timezone option)Lennart Poettering
This one is simply to add: encode the tzdata timezone in the DHCP options and optionally make use of it.
2015-08-26networkd: don't leak memory of Hostname= is used twice in a .network fileLennart Poettering
Also, we should only accept trailing dots where we have to, but not everywhere, hence be more strict when validating configured hostnames.
2015-08-26sd-dhcp: don't randomly ref objectsDavid Herrmann
In our API design, getter-functions don't ref objects. Calls like foo_get_bar() will not ref 'bar'. We never do that and there is no real reason to do it in single threaded APIs. If you need a ref-count, you better take it yourself *BEFORE* doing anything else on the parent object (as this might invalidate your pointer). Right now, sd_dhcp?_get_lease() refs the lease it returns. A lot of code-paths in systemd do not expect this and thus leak the lease reference. Fix this by changing the API to not ref returned objects.
2015-08-25sd-network: make LLMNR specific config parser genericDaniel Mack
Rename the enum, the lookup functions and the parser for LLMNRSupport so the type can be reused for mDNS.
2015-08-21network: Save DNS and NTP data for a DHCPv6 linkPatrik Flykt
Append DNS and NTP data obtained via DHCPv6 when the Link is saved.
