2015-08-27tree-wide: we place the opening bracket on the same line as the function nameLennart Poettering
Let's do this everywhere the same way.
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: generic data should be void*, not uint8_t*Lennart Poettering
If we handly arbitrary data we should use "void*" pointers, not "uint8_t*", how go intended C to be used.
2015-08-26network: s/user_data/userdata/Lennart Poettering
Everywhere else we call the generic user data pointer just "userdata", rather than "user_data". Let's do this here, too.
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.
2015-02-23remove 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.

2015-02-02test-dhcp-client: open a real udp socket for test executionZbigniew Jędrzejewski-Szmek
./test-dhcp-client would attempt to operate fd 0, i.e. stdin. For example, './test-dhcp-client </dev/null' would fail with EPERM because /dev/null cannot be used with epoll. https://bugzilla.redhat.com/show_bug.cgi?id=1076119

2015-01-22sd-dhcp-client: use RFC4361-complient ClientID by defaultTom Gundersen
In addition to the benefits listed in the RFC, this allows DHCP to work also in case several interfaces share the same MAC address on the same link (IPVLAN). Note that this will make the ClientID (so probably the assigned IP address) change on upgrades. If it is desired to avoid that we would have to remember and write back the ID (which the library supports, but networkd currently does not).
2014-10-13test-dhcp-client: add more assertsTom Gundersen
2014-10-11sd-dhcp-client: support non-Ethernet hardware addressesDan Williams
Like Infiniband. See RFC 4390 section 2.1 for details on DHCP and Infiniband; chaddr is zeroed, hlen is set to 0, and htype is set to ARPHRD_INFINIBAND because IB hardware addresses are 20 bytes in length.
2014-07-24libsystemd-network: use CLOCK_BOOTTIME instead of CLOCK_MONOTONIC where possibleTom Gundersen
The timeouts in the networking library (DHCP lease timeouts and similar) should not be affected by suspend. In the cases where CLOCK_BOOTTIME is not implemented, it is still safe to fallback to CLOCK_MONOTONIC, as the consumers of the library (i.e., networkd) _should_ renew the leases when coming out of suspend.
2014-07-07dhcp-network: add check for DHCP.chaddrMichal Sekletar
Check that received DHCP packets actually include our MAC address in chaddr field. BPF interpreter has 32 bit wide registers but MAC address is 48 bits long so we have to do check in two steps.
2014-06-17sd-dhcp: checksum - make endianess-neutralTom Gundersen
For efficiency, we group bytes together before adding them up. This is guaranteed to always work (regardless of the byte order) as long as the i-th byte in each group lign up with the i-th byte in each other group. On big-endian machines this broke when handling the trailing few bytes which did not make up a full group of 4 bytes. This patch fixes the problem by explicitly creating a 4 byte zero-padded group out of the trailing bytes. Reported and tested by Thomas Ritter <th.ritter@gmx.at>.
2014-05-06dhcp-network: don't pass ifindex to bind_udp_socketTom Gundersen
UDP sockets can anyway not be bound to specific netdev's. The packages would have to be filtered when received instead.
2014-04-27libnetworkd: add link local testsUmut Tezduyar Lindskog
- Also only allow positive ifindex on both dhcp and ipv4ll [tomegun: the kernel always sets a positive ifindex, but some APIs accept ifindex=0 with various meanings, so we should protect against accidentally passing ifindex=0 along.]
2014-04-12test-dhcp-client: unref lease objects to make valgrind happyZbigniew Jędrzejewski-Szmek
Also unref client objects in test code, and initalize logging, to DEBUG by default.
2014-04-11sd-dhcp-client: Add reference counting for DHCPPatrik Flykt
The DHCP library user can decide to free the DHCP client any time the callback is called. After the callback has been called, other computations may still be needed - the best example being a full restart of the DHCP procedure in case of lease expiry. Fix this by introducing proper reference counting. Properly handle a returned NULL from the notify and stop functions if the DHCP client was freed.
2014-04-10sd-dhcp-client: test - fix for jenkinsTom Gundersen
This test should have been updated when changing the magic cookie handling around. Reported by Ken MacLeod.

2014-04-06sd-dhcp-client: improve BPFTom Gundersen
Try a bit harder to make the kernel drop packets not for us. This should reduce the number of wakeups from n^2 to n in the number of dhcp clients, which admittedly only makes a differenc in very extreme cases.
2014-03-24sd-event: rework API to support CLOCK_REALTIME_ALARM and ↵Lennart Poettering
CLOCK_BOOTTIME_ALARM, too
2014-03-22sd-dhcp-client: test - don't close socket twiceTom Gundersen
One end of the socketpair is closed by the library, so only close our end. Also switch to the safe_close() so we get notified about problems with closing.
2014-03-20libsystemd-dhcp: Update client test case for client id and end optionPatrik Flykt
Check that the client identifier is formatted as suggested in the RFC and that the messages sent ends with an end option.
2014-03-19libsystemd-network: Add hangcheck timer for DHCP client testPatrik Flykt
2014-03-19libsystemd-network: Export checksum function to test casePatrik Flykt
Remove identical checksum function implementation from the test case code.
2014-03-12test-dhcp-client: remove pointless initializer, wrongly committed earlierKay Sievers
2014-03-11build-sys: add libsystemd-label to network/dhcp usersKay Sievers
2014-02-28sd-network: add new libraryTom Gundersen
This is similar to sd-login, but exposes the state of networkd rather than logind. Include it in libsystemd-dhcp and rename it to libsystemd-network.
