2015-07-15sd-bus: fix object tree to be deeper than 2 levelsDavid Herrmann
So right now our object-tree is limited to 2 levels at most ('/' and '/foo/...../bar'). We never link any intermediate levels, even though that was clearly the plan. Fix the bus_node_allocate() helper to actually link all intermediate nodes, too, not just the root node. This fixes a simple inverse ptr-diff bug. The downside of this fix is that we clearly never tested (nor used) the object tree in any way. The only reason that the introspection works is that our enumerators shortcut the object tree. Lets see whether that code actually works.. Thanks to: Nathaniel McCallum <nathaniel@themccallums.org> ..for reporting this. See #524 for an actual example code.
2015-07-15sd-device: never return NULL+0David Herrmann
It is highly confusing if a getter function returns 0, but the value is set to NULL. This, right now, triggers assertions as code relies on the returned values to be non-NULL. Like with sd-bus-creds and friends, return 0 only if a value is actually available. Discussed with Tom, and actually fixes real bugs as in #512.
2015-07-15sd-boot: ignore missing /etc/machine-idDavid Herrmann
If /etc/machine-id is missing (eg., gold images), we should not fail installing sd-boot. This is a perfectly fine use-case and we should simply skip installing the default loader config in that case.

sd-dhcp-lease: fix handling of multiple routers We only support one router, but in case more than one is given, we now ignore subsequent ones, rather than fall over.

2015-07-14resolved: use one UDP socket per transactionTom Gundersen
We used to have one global socket, use one per transaction instead. This has the side-effect of giving us a random UDP port per transaction, and hence increasing the entropy and making cache poisoining significantly harder to achieve. We still reuse the same port number for packets belonging to the same transaction (resent packets).
2015-07-14resolved: implement RFC5452Tom Gundersen
This improves the resilience against cache poisoning by being stricter about only accepting responses that match precisely the requst they are in reply to. It should be noted that we still only use one port (which is picked at random), rather than one port for each transaction. Port randomization would improve things further, but is not required by the RFC.
2015-07-14resolved: pin the server used in a transactionTom Gundersen
We want to discover information about the server and use that in when crafting packets to be resent.

We want to reference the servers from their active transactions, so make sure they stay around as long as the transaction does.

2015-07-14networkd: tap add support for vnet_hdrSusant Sahani
This patch adds support to configure IFF_VNET_HDR flag for a tap device. It allows whether sending and receiving large pass larger (GSO) packets. This greatly increases the achievable throughput.

2015-07-13resolved: make LLMNR checks conditionalDaniel Mack
Make all LLMNR related packet inspections conditional to p->protocol. Use switch-case statements while at it, which will make future additions more readable.
2015-07-13resolved: separate LLMNR specific header bitsDaniel Mack
The C and T bits in the DNS packet header definitions are specific to LLMNR. In regular DNS, they are called AA and RD instead. Reflect that by calling the macros accordingly, and alias LLMNR specific macros. While at it, define RA, AD and CD getters as well.
2015-07-13resolved: use a #define for LLMNR portDaniel Mack
De-duplicate some magic numbers.

2015-07-12dhcp: add support for vendor specific DHCP optionBeniamino Galvani
This adds support for option 43 (Vendor Specific Information) to libsystemd-network DHCP code. The option carries an opaque object of n octets, interpreted by vendor-specific code on the clients and servers. [@zonque: adopted to new unhexmem() API]
2015-07-12basic: util - add base64mem() function similar to hexmem()Tom Gundersen
This implements RFC4648 for a slightly more compact representation of binary data compared to hex (6 bits per character rather than 4).
2015-07-12basic: util - fix errorhandling in unhexmem()Tom Gundersen
We were ignoring failures from unhexchar, which meant that invalid hex characters were being turned into garbage rather than the string rejected. Fix this by making unhexmem return an error code, also change the API slightly, to return the size of the returned memory, reflecting the fact that the memory is a binary blob,and not a string. For convenience, still append a trailing NULL byte to the returned memory (not included in the returned size), allowing callers to treat it as a string without doing a second copy.

logind: bring bus policy up-to-date
2015-07-11sd-dhcp-lease: fix handling of multiple routersNick Owens
currently if a dhcp server sends more than one router, sd-dhcp-lease does not copy the ip because it assumes it will only ever be 4 bytes. a dhcp server could send more than one ip in the router list, so we should copy the first one and ignore the rest of the bytes.
2015-07-11logind: some firmware implementations remove OsIndications if it is unsetLennart Poettering
We shouldn't fall over that, and just assume it is 0 in this case. Fixes #499.
2015-07-11logind: bring bus policy up-to-dateLennart Poettering
A while back we opened up all of logind's bus calls to unprivileged users, via PK. However, the dbus1 policy wasn't updated accordingly. With this change, the dbus1 policy is opened up for all bus calls that should be available to unprivileged clients. (also rearranges some calls in the vtable, to make more sense, and be in line with the order in the bus policy file) Fixes #471.

2015-07-10logind: rename 'pos' to 'position'David Herrmann
Spell out the proper name. Use 'pos' over 'position', and also update the logind state file to do the same. Note that this breaks live updates. However, we only save 'POSITION' on non-seat0, so this shouldn't bother anyone for real. If you run multi-seat setups, you better restart a machine on updates, anyway.
2015-07-10logind: allow greeters to take over VTsDavid Herrmann
Make sure a greeter can forcefully spawn a session on a VT that is in-use. A recent patch prevented this (this used to be possible for all session types) as it is highly fragile. However, as it turns out, greeters seem to rely on that feature. Therefore, make sure we allow it explicitly for greeters.

sd-bus: sd_bus_slot_get_description() should return const strings
2015-07-09sd-bus: include queried path in GetManagedObjectsDavid Herrmann
If GetManagedObjects is called on /foo/bar, then it should also include the object /foo/bar, if it exists. Right now, we only include objects underneath /foo/bar/. This follows the behavior of existing dbus implementations. Obsoletes #527 and fixes #525. Reported by: Nathaniel McCallum
2015-07-09boot: use BUILD_ID if VERSION_ID is not presentDavid Herrmann
According to os-release(5), VERSION_ID is not mandatory and BUILD_ID only needs to be unique underneath VERSION_ID. Therefore, assuming a missing VERSION_ID field means 'empty', we can rely on BUILD_ID to be unique. Use BUILD_ID if VERSION_ID is not present. This way, rolling-release distros can still provide a proper os-release entry without crafting random VERSION_ID strings. This fixes #186.
2015-07-09boot: fix memleaks in os-release parserDavid Herrmann
There is no guarantee that the os-release section contains each key only once, nor any guarantee that all keys are present. Make sure we properly free memory in both cases. Not that it matters much, as we're short-living, anyway. But correct code is always nicer to read..
2015-07-09resolve-host: enable dbus-activationDavid Herrmann
Right now, systemd-resolve-host fails if resolved is not running. However, resolved supports bus-activation (at least on kdbus) just fine. Enable this so we can use resolve-host at all times. This was disabled right from the beginning, without any comment why.
2015-07-09sd-bus: sd_bus_slot_get_description() should return const stringsDavid Herrmann
All other *_get_description() functions use 'const char**', so make sure sd_bus_slot_get_description() does the same. This changes API, but ABI stays stable. I think this is fine, but I wouldn't mind bumping SONAME. Reported in #528.
