2015-10-06test: hashmap - increase number of entries for crippled hash testMichal Schmidt
The purpose of testing with the crippled hash function is to cover the otherwise very unlikely codepath in bucket_calculate_dib() where it has to fall back to recomputing the hash value. This unlikely path was not covered by test-hashmap anymore after 57217c8f "test: hashmap - cripple the hash function by truncating the input rather than the output". Restore the test coverage by increasing the number of entries in the test. The number was determined empirically by checking with lcov.

2015-10-06core: add support for naming file descriptors passed using socket activationLennart Poettering
This adds support for naming file descriptors passed using socket activation. The names are passed in a new $LISTEN_FDNAMES= environment variable, that matches the existign $LISTEN_FDS= one and contains a colon-separated list of names. This also adds support for naming fds submitted to the per-service fd store using FDNAME= in the sd_notify() message. This also adds a new FileDescriptorName= setting for socket unit files to set the name for fds created by socket units. This also adds a new call sd_listen_fds_with_names(), that is similar to sd_listen_fds(), but also returns the names of the fds. systemd-activate gained the new --fdname= switch to specify a name for testing socket activation. This is based on #1247 by Maciej Wereski. Fixes #1247.

2015-10-06core: simplify fd collection code, return number of fds as return valueLennart Poettering
Let's simplify the fd collection code a bit, and return the number of collected fds as positive integer, the way it's customary in our usual code.

2015-10-05document ability to disable MACAddressPolicyJacob Keller
While it is currently possible to either not set MACAddressPolicy or set it to a value different from "persistent" or "random", it is not obvious that a user can do so. Add a policy, "none", which simply retains kernel MAC addresses (same as not filling in the policy at all) and document it so that users are aware of this setting.

2015-10-06libsystemd: sd-device - translate / vs. ! in sysnameKay Sievers
The kernel replaces '/' in device names with '!', we translate that back to '/' in sysname, when taking sysname as input, we should translate it back again.

2015-10-05hashmap: hash_funcs - make inputs unambiguousTom Gundersen
Make sure all variable-length inputs are properly terminated or that their length is encoded in some way. This avoids ambiguity of adjacent inputs. E.g., in case of a hash function taking two strings, compressing "ab" followed by "c" is now distinct from "a" followed by "bc".
2015-10-05hashmap: refactor hash_funcTom Gundersen
All our hash functions are based on siphash24(), factor out siphash_init() and siphash24_finalize() and pass the siphash state to the hash functions rather than the hash key. This simplifies the hash functions, and in particular makes composition simpler as calling siphash24_compress() repeatedly on separate chunks of input has the same effect as first concatenating the input and then calling siphash23_compress() on the result.
2015-10-05test: hashmap - cripple the hash function by truncating the input rather ↵Tom Gundersen
than the output The reason for the crippled hash function is to reduce the distribution of the hash function, do this by truncating the domain rather than the range. This does introduce a change in behavoir as the range is no longer contiguous, which greatly reduces collisions. This is needed as a follow-up patch will no longer allow individual hash functions to alter the output directly.
2015-10-05test: siphash24 - verify internal state and composabilityTom Gundersen
Verify the state of the hash-function according to the reference paper, also verify that we can decompose the input and hash the chunks one by one and still get the same result.

2015-10-05siphash24: make siphash24_compress decomposableTom Gundersen
This allows the input to siphash24_compress to be decomposed into smaller chunks and the function to be called on each individual chunk.
2015-10-05siphash24: move last compression iteration from compression step to ↵Tom Gundersen
finalization step The last compression is special as it deals with the length byte, and padding. Move it to the finalization step in preparation for making compression decomposable.

2015-10-05sd-rtnl: introduce new API to set the NL header flagsSusant Sahani
By default we set as NLM_F_CREATE | NLM_F_EXCL in sd_rtnl_message_new_link But incase of bridge we need to set NLM_F_REQUEST | NLM_F_ACK. If NLM_F_EXCL is set then we are unable to set the parameters. As bridge supports setting properties after creation not during creation.

2015-10-03core: don't unset reload result, unless we begin a start or reload operationLennart Poettering
Much like the result of the service itself we should not reset the reload result unless we actually start from the beginning, so that clients can query it at any time. Specifically, let's reset the result states only when we begin with a start operation (for both the main result, and the reload result), when we begin with a reload operation (only for the load result), or when the use explicitly asks for that via "systemctl reset-failed". This is a more generic fix for #1447. Fixes #1447.
2015-10-02journal: rework vacuuming logicLennart Poettering
Implement a maximum limit on number of journal files to keep around. Enforcing a limit is useful on this since our performance when viewing pays a heavy penalty for each journal file to interleve. This setting is turned on now by default, and set to 100. Also, actully implement what 348ced909724a1331b85d57aede80a102a00e428 promised: use whatever we find on disk at startup as lower bound on how much disk space we can use. That commit introduced some provisions to implement this, but actually never did. This also adds "journalctl --vacuum-files=" to vacuum files on disk by their number explicitly.

2015-10-02journal: don't affect atime of journal files when vacuumingLennart Poettering

2015-10-02lldp: fix parsing of TLV lengthBeniamino Galvani
tlv_packet_read_bytes() and tlv_packet_read_string() returned the wrong length when called after other functions which modify the offset in the container. In other words, if the TLV data length is X and we do a tlv_packet_read_u8(), a subsequent tlv_packet_read_bytes() should return a length of (X - 1).
2015-10-02lldp: move lldp_receive_packet() to lldp-internal.cBeniamino Galvani
In order to implement tests for the LLDP state machine, we need to mock lldp_network_bind_raw_socket(). Move the other function lldp_receive_packet() to another file so that we can replace the first function with a custom one and keep the second one.

2015-10-02lldp: add support for organizationally specific TLVsBeniamino Galvani
LLDP TLVs of type 127 are used to carry organizationally specific information and include additional fields to specify the OUI and subtype. Add support for parsing such fields and functions to access the most common IEEE 802.1 specific TLVs.
