2015-08-27dhcp: fix n_ref typeLennart Poettering
Fixes fallout from 3733eec3e292e4ddb4cba5eb8d3bd8cbee7102d8.
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.
2015-08-27networkd: 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.
2015-08-27man: document the new DHCP settings added in the past commitsLennart Poettering
2015-08-27NEWS: updatesystemd/v225David Herrmann
Add 'machinectl shell' to NEWS and also update date and contributors lists.
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.
2015-08-27sd-bus: do not connect to dbus-1 socket when kdbus is availableDavid Herrmann
We should not fall back to dbus-1 and connect to the proxy when kdbus returns an error that indicates that kdbus is running but just does not accept new connections because of quota limits or something similar. Based on a patch by Kay.
2015-08-27Revert "sd-bus: do not connect to dbus-1 socket when kdbus is available"David Herrmann
This reverts commit d4d00020d6ad855d65d31020fefa5003e1bb477f. The idea of the commit is broken and needs to be reworked. We really cannot reduce the bus-addresses to a single address. We always will have systemd with native clients and legacy clients at the same time, so we also need both addresses at the same time.
2015-08-27selinux: drop mac_selinux_unit_access_check_strv()David Herrmann
It is not acceptable to load unit files during enable/disable operations just to figure out the selinux labels. systemd implements lazy loading for units, so the selinux hooks need to follow it. This drops the mac_selinux_unit_access_check_strv() helper which implements a non-acceptable policy check. If anyone cares for that functionality, you really should pass a callback+userdata to the helpers in src/shared/install.c which does policy checks on each touched file. See #1050 on github for more.
2015-08-27sd-bus: rename bloom-tag to arg0-hasDavid Herrmann
We use dashes in our bloom-tags. Make sure the newly introduced arg0has tag uses the same style. Note that the external dbus-tags don't use dashes, though. They are defined in the spec and we need to keep compatibility there.

sd-bus: introduce new SD_BUS_VTABLE_PROPERTY_EXPLICIT flag
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.
2015-08-27udev: control - add FIXME comment to remove work-aroundKay Sievers
2015-08-27sd-bus: it's not a user error to query the error contained in a bus messageLennart Poettering
It's an OK way to check whether a message contains an erro, let's not consider this a loggable assertion event.
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: don't underflow in lease time calculationsLennart Poettering
Don't underflow when calculating lease time.
2015-08-27networkd: make DHCP lease timeouts configurableLennart Poettering
2015-08-27networkd: fix indentationLennart 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.
2015-08-27dhcp: clean up dhcp4 lease objectLennart Poettering
a) drop handling of obsolete or unused DHCP options time_offset, mtu_aging_timeout, policy filter, mdr, ttl, ip forwarding settings. Should this become useful one day we can readd support for this. b) For subnet mask and broadcast it is not always clear whether 0 or 255.255.255.255 might be valid, hence maintain a boolean indicating validity next to it. c) serialize/deserialize broadcast address, lifetime, T1 and T2 together with the rest of the fields in dhcp_lease_save() and dhcp_lease_load(). d) consistently return ENODATA from getter functions for data that is missing in the lease. e) add missing getter calls for broadcast, lifetime, T1, T2. f) when decoding DHCP options, generate debug messages on parse failures, but try to proceed if possible. g) Similar, when deserializing a lease in dhcp_lease_load(), make sure we deal nicely with unparsable fields, to provide upgrade compat. h) fix some memory allocations
2015-08-26dhcp: rename index to ifindexLennart Poettering
This avoids confusion what this is, in particular as libc knows an index() function.
2015-08-26dhcp: store client id as void*, since we dont know what it isLennart Poettering
2015-08-26dhcp: properly handle error from ioctl()Lennart Poettering
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.
2015-08-26dhcp: coding style fixesLennart Poettering
We place the opening bracket of a function on the same line as the function name. Let's do so in the DHCP sources too.
2015-08-26dhcp: stop using refcnt.hLennart Poettering
No need to invole atomic ops in single-threaded APIs, let's simplify this.
2015-08-26basic: document that people shouldn't use refcnt.h without reasonLennart Poettering
refcnt.h only exists for cases where objects are simultaneously handled by different threads. Otherwise it should not be used. The only case where this applies is sd_bus, really, and pretty much none of our APIs, since we do not claim thread-safety for them.
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: normalize DHCP host and domain names from leasesLennart Poettering
Previoulsy, we just checked whether the domain names specified in incoming DHCP leases are valid. Given that validation code actually internally normalizes anyway, it's a good idea to simply do the full normalization and store that in the lease structure. This allows us to remove the manual removal of a trailing dot, if there is one.
2015-08-26dhcp: various simplificationsLennart Poettering
2015-08-26network: turn on DHCP timezone passing between container and hostLennart Poettering
Let's turn on DHCP timezone passing from the host to a container, so that the timezone is always in sync.
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.
2015-08-26dhcp: be more careful when parsing strings from DHCP packetsLennart Poettering
Let's make sure there's no embedded 0 byte. Also, let's reset the string if the length is zero.
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.
2015-08-26time-util: add new get_timezone() call to get local timezoneLennart Poettering
Let's move the timedated-specific code to time-util.h and make it generic.

2015-08-26sd-dhcp6: fix domainname memleakDavid Herrmann
strv_extend() does not consume the passed entry, hence, we must properly free it. Furthermore, we should *not* use strv_consume() as we do greedy allocations on 'ret'; and greedy-allocations should only be used for short lived objects or caches. Fix the domainname parser to properly free temporary storage when done.
