2016-02-21networkctl: extend "networkctl list" and "networctl lldp" to optionally take ↵Lennart Poettering
interface names This way, the output may be reduced to only show data about the specified interfaces.
2016-02-21networkctl: add new call that unifies link data acquisition between "status" ↵Lennart Poettering
and "lldp" verbs
2016-02-21networkctl: fix dispatch_verb() tableLennart Poettering
VERB_DEFAULT may only appear once.

2016-02-21sd-lldp: rework sd-lldp APILennart Poettering
This reworks the sd-lldp substantially, simplifying things on one hand, and extending the logic a bit on the other. Specifically: - Besides the sd_lldp object only one other object is maintained now, sd_lldp_neighbor. It's used both as storage for literal LLDP packets, and for maintainging info about peers in the database. Separation between packet, TLV and chassis data is not maintained anymore. This should be a major simplification. - The sd-lldp API has been extended so that a couple of per-neighbor fields may be queried directly, without iterating through the object. Other fields that may appear multiple times, OTOH have to be iterated through. - The maximum number of entries in the neighbor database is now configurable during runtime. - The generation of callbacks from sd_lldp objects is more restricted: callbacks are only invoked when actual data changed. - The TTL information is now hooked with a timer event, so that removals from the neighbor database due to TTLs now result in a callback event. - Querying LLDP neighbor database will now return a strictly ordered array, to guarantee stability. - A "capabilities" mask may now be configured, that selects what type of LLDP neighbor data is collected. This may be used to restrict collection of LLDP info about routers instead of all neighbors. This is now exposed via networkd's LLDP= setting. - sd-lldp's API to serialize the collected data to text files has been removed. Instead, there's now an API to extract the raw binary data from LLDP neighbor objects, as well as one to convert this raw binary data back to an LLDP neighbor object. networkd will save this raw binary data to /run now, and the client side can simply parse the information. - support for parsing the more exotic TLVs has been removed, since we are not using that. Instead there are now APIs to extract the raw data from TLVs. Given how easy it is to parse the TLVs clients should do so now directly instead of relying on our APIs for that. - A lot of the APIs that parse out LLDP strings have been simplified so that they actually return strings, instead of char arrays with a length. To deal with possibly dangerous characters the strings are escaped if needed. - APIs to extract and format the chassis and port IDs as strings has been added. - lldp.h has been simplified a lot. The enums are anonymous now, since they were never used as enums, but simply as constants. Most definitions we don't actually use ourselves have eben removed.
2016-02-20core: exclude .slice units from "systemctl isolate"Lennart Poettering
Fixes: #1969
2016-02-20networkd: fix logging of error codesLennart Poettering
2016-02-20networkd: enable LLDP only on ethernetLennart Poettering
2016-02-20sd-netlink: fix ifi_iftype typeLennart Poettering
The iftype is an unsigned short, and not just an unsigned.
2016-02-20sd-lldp: fix how we create the LLDP listening socketLennart Poettering
Specifiy the ethernet family, and make sure we se the O_CLOEXEC and O_NONBLOCK bits how we should for all fds.
2016-02-20tree-wide: place #pragma once at the same place everywhereLennart Poettering
Usually, we place the #pragma once before the copyright blurb in header files, but in a few cases we didn't. Move those around, so that we do the same thing everywhere.
2016-02-20sd-lldp: simplify lldp_network_bind_raw_socket() a bitLennart Poettering
Let's constify the filter program, drop a few includes and structure definitions.
2016-02-20sd-lldp: move ETHERTYPE_LLDP to missing.hLennart Poettering
After all, most ETHERTYPE variables are defined in the system headers, hence define these where we defined all other fill-ins for system headers.

2016-02-20libsystemd-network: sd-event uses 64bit priorities, expose them in the APIs ↵Lennart Poettering
as such
2016-02-20sd-lldp: drop "port" objectLennart Poettering
Let's just keep the few parts we actually need of it in the main sd_lldp object, so that we can simplify things quite a bit. While we are at it, remove ifname and mac fields which we make no use of whatsoever.
2016-02-20sd-lldp: drop keeping of statisticsLennart Poettering
We don't expose them, and they are only of questionnable use.
2016-02-20libsystemd-network: don't abbreviate "callback" as "cb" needlesslyLennart Poettering
This isn't an excercise in creating APIs that are hard to understand, hence let's call a callback a callback.
2016-02-20sd-lldp: drop state fieldLennart Poettering
There's really no point in maintaining a state, the state machine is trivial, and we actually never look at the state anyway, we just keep updating it.

2016-02-19udev/path_id: correct segmentation fault due to missing NULL checkHendrik Brueckner
Running "udevadm test-builtin path_id /sys/devices/platform/" results in a segmentation fault. The problem is that udev_device_get_subsystem(dev) might return NULL in a streq() call. Solve this problem by using streq_ptr() instead.

2016-02-18journal/catalog: fix memory leaksZbigniew Jędrzejewski-Szmek
Various buffers were lost because finish_item() either consumed the buffer or allocated a new one (if an entry with the same key existed). The caller would simply forget the buffer in either case. Also add a check for the case when a valid identifier is followed by an empty body. We should not allow this. Also be more consistent in error handling and always print an error message.

alloc-util: extract overflow check into inline function
2016-02-19alloc-util: cleanupsAlexander Kuleshov
This patch contains a set of little cleanups for alloc-util.h: 1. The malloc_multiply(), realloc_multiply() and memdup_multiply() functions check allocation related parameters on overflow. Let's move them to the separate size_multiply_overflow() function for simplicity, code duplication prevention and possible reuse in future. 2. use SIZE_MAX from stdlib instead of ((size_t) - 1) to be more clear. 3. The 'a'/'b' variables are renamed to 'size' and 'need' to be more clear.'

resolve: dumping of binary packets
2016-02-16test-resolve-tables: verify that dns type/class length is within limitsZbigniew Jędrzejewski-Szmek
DNS_TYPE_STRING_MAX causes a problem with the table autogeneration code, change to _DNS_TYPE_STRING_MAX.
2016-02-16Use provided buffer in dns_resource_key_to_stringZbigniew Jędrzejewski-Szmek
When the buffer is allocated on the stack we do not have to check for failure everywhere. This is especially useful in debug statements, because we can put dns_resource_key_to_string() call in the debug statement, and we do not need a seperate if (log_level >= LOG_DEBUG) for the conversion. dns_resource_key_to_string() is changed not to provide any whitespace padding. Most callers were stripping the whitespace with strstrip(), and it did not look to well anyway. systemd-resolve output is not column aligned anymore. The result of the conversion is not stored in DnsTransaction object anymore. It is used only for debugging, so it seems fine to generate it when needed. Various debug statements are extended to provide more information.
2016-02-16Replace DNS_RESOURCE_KEY_NAME with a version which always returns "." for rootZbigniew Jędrzejewski-Szmek
This fixes formatting of root domain in debug messages: Old: systemd-resolved[10049]: Requesting DS to validate transaction 19313 (., DNSKEY with key tag: 19036). New: systemd-resolved[10049]: Requesting DS to validate transaction 19313 (, DNSKEY with key tag: 19036).
