2015-11-19nd-ndisc: don't fail if src address is unsetTom Gundersen
This happens when running our test-suite over a socketpair, so don't fall over in that case. Fixes issue #1952.

libsystemd-network: add support for "Client FQDN" DHCP option (v2)
2015-11-19sd-ndisc: drop RA packets from non-link-local addressesTom Gundersen
See https://tools.ietf.org/html/rfc4861#section-4.2. Some routers (dnsmasq) will send packets from global addresses, which would break the default route setup, so ignore those. This is also what the kernel does.

This is a continuation of the previous include sort patch, which only sorted for .c files.

2015-11-17libsystemd-network: add support for "Client FQDN" DHCP optionBeniamino Galvani
This adds support for the Client Fully Qualified Domain Name (FQDN) option [RFC 4702] to libsystemd-network. The option can be used to exchange information about a DHCPv4 client's fully qualified domain name and about responsibility for updating the DNS RR related to the client's address assignment. Other popular DHCP clients (dhclient, dhcpcd) support this option and it would be useful to have it in networkd too.
2015-11-17sd-dhcp6-client: bind to link-local addressTom Gundersen
This ensures that several DHCPv6 clients can run on separate interfaces simultaneously.
2015-11-17sd-dhcp6-client: allow multiple clients on hostTom Gundersen
We need to enable SO_REUSEADDR in order for several sockets to be allowed to bind to the same port (even on different links).

2015-11-16siphash24: let siphash24_finalize() and siphash24() return the result directlyDaniel Mack
Rather than passing a pointer to return the result, return it directly from the function calls. Also, return the result in native endianess, and let the callers care about the conversion. For hash tables and bloom filters, we don't care, but in order to keep MAC addresses and DHCP client IDs stable, we explicitly convert to LE.

2015-11-16networkd: ndisc/dhcpv6 - handle starting running clientsTom Gundersen
The clients may be triggered to be started repeatedly without being stopped first, simply swallow the error rather than failing the link.
2015-11-16siphash24: change result argument to uint64_tMartin Pitt
Change the "out" parameter from uint8_t[8] to uint64_t. On architectures which enforce pointer alignment this fixes crashes when we previously cast an unaligned array to uint64_t*, and on others this should at least improve performance as the compiler now aligns these properly. This also simplifies the code in most cases by getting rid of typecasts. The only place which we can't change is struct duid's en.id, as that is _packed_ and public API, so we can't enforce alignment of the "id" field and have to use memcpy instead.

2015-11-11networkd: ndisc - handle router advertisement in userspaceTom Gundersen
Router Discovery is a core part of IPv6, which by default is handled by the kernel. However, the kernel implementation is meant as a fall-back, and to fully support the protocol a userspace implementation is desired. The protocol essentially listens for Router Advertisement packets from routers on the local link and use these to configure the client automatically. The four main pieces of information are: what kind (if any) of DHCPv6 configuration should be performed; a default gateway; the prefixes that should be considered to be on the local link; and the prefixes with which we can preform SLAAC in order to pick a global IPv6 address. A lot of additional information is also available, which we do not yet fully support, but which will eventually allow us to avoid the need for DHCPv6 in the common case. Short-term, the reason for wanting this is in userspace was the desire to fully track all the addresses on links we manage, and that is not possible for addresses managed by the kernel (as the kernel does not expose to us the fact that it manages these addresses). Moreover, we would like to support stable privacy addresses, which will soon be mandated and the legacy MAC-based global addresses deprecated, to do this well we need to handle the generation in userspace. Lastly, more long-term we wish to support more RA options than what the kernel exposes.
2015-11-11sd-ndisc: introduce separate callbacksTom Gundersen
As the data passed is very different, we introduce four different callbacks: - Generic - router discovery timed out or state machine stopped - Router - router and link configuration received - Prefix onlink - configuration for an onlink prefix received - Prefix autonomous - configuration for to configure a SLAAC address for a prefix received
2015-11-11sd-ndisc: notify user on STOPTom Gundersen
Also, stop the state machine when we get into a broken state, rather than just notify the user.

2015-11-03sd-pppoe: dropTom Gundersen
It is really unclear if we want to / have the resources to support this fully, so drop it for now. It can easily be brought back if a killer usecase emerges. Note that this code was never hooked up, so this does not remove any features.

There are more than enough to deserve their own .c file, hence move them over.
2015-10-24sd-*.h: clean up exported (or to-be-exported) header filesLennart Poettering
Exported header files should not include internal headers. Fix that. Exported header files should not use the bool type. So far we opted to stick to C89 for exported headers, and hence use "int" for bools in them. Continue to do so. Exported header files should have #include lines for everything they use including inttypes.h and sys/types.h, so that they may be included in any order. Exported header files should have C++ guards, hence add them. Exported header files should not use gcc extensions like #pragma once, get rid of it.
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-10-22sd-ndisc: reduce callbacksTom Gundersen
Only callback on error when the statemachine is in a truly broken state. This is now only the case when we fail to rearm a timer.
2015-10-22sd-ndisc: drop sd_ndisc_get_prefixlen()Tom Gundersen
This is unused, and in the future we will pass prefixes and prefixlengths directly to the callbacks when needed rather than having to search for them.
2015-10-22sd-ndisc: drop sd_ndisc_prefix_match()Tom Gundersen
This is no longer used.
2015-10-22sd-ndisc: don't trigger timeout on prefix expiryTom Gundersen
The caller of the library is no longer notified, so triggering a timer just to clean up is not necessary. Instead check for and clean up invalid prefixes lazily.
2015-10-22sd-ndisc: remove a prefix from the ndisc object when freeing itTom Gundersen
This follows the coding style, and allows some simplification to the rest of the code.
2015-10-22sd-ndisc: don't inform the caller of expired prefixesTom Gundersen
The caller should push any lifetime information into the kernel and let the kernel handle prefix expiration.
2015-10-22sd-ndisc: clean up state enumTom Gundersen
There is no need to assign valuse to the states. Also add _INVALID and _MAX, even though these are not used, it keeps it consistent.
