lldp fixes, second iteration
2016-02-21sd-network: use xsprintf() instead of asprintf() where we canLennart Poettering
2016-02-21networkd: rework how carrier bindings are serializedLennart Poettering
Instead of serializing the interface name, expose the interface index, since that's the only stable identifier.
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.
2016-02-20sd-device: use (void) before set_iterate callsZbigniew Jędrzejewski-Szmek
set_iterate sets the output argument to NULL on error, and the return value is not used in this case. CID #1306804-09.
2016-02-20sd-netlink: fix ifi_iftype typeLennart Poettering
The iftype is an unsigned short, and not just an unsigned.
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.

2016-02-12remove bus-proxydDaniel Mack
As kdbus won't land in the anticipated way, the bus-proxy is not needed in its current form. It can be resurrected at any time thanks to the history, but for now, let's remove it from the sources. If we'll have a similar tool in the future, it will look quite differently anyway. Note that stdio-bridge is still available. It was restored from a version prior to f252ff17, and refactored to make use of the current APIs.
2016-02-11Remove kdbus custom endpoint supportDaniel Mack
This feature will not be used anytime soon, so remove a bit of cruft. The BusPolicy= config directive will stay around as compat noop.
2016-02-11Add memcpy_safeZbigniew Jędrzejewski-Szmek
ISO/IEC 9899:1999 §7.21.1/2 says: Where an argument declared as size_t n specifies the length of the array for a function, n can have the value zero on a call to that function. Unless explicitly stated otherwise in the description of a particular function in this subclause, pointer arguments on such a call shall still have valid values, as described in 7.1.4. In base64_append_width memcpy was called as memcpy(x, NULL, 0). GCC 4.9 started making use of this and assumes This worked fine under -O0, but does something strange under -O3. This patch fixes a bug in base64_append_width(), fixes a possible bug in journal_file_append_entry_internal(), and makes use of the new function to simplify the code in other places.
2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-02-09core: change internal error code for masked units from EBADR to ESHUTDOWNLennart Poettering
This commit changes the mapping of the BUS_ERROR_UNIT_MASKED error to ESHUTDOWN. This error is used whenever the transaction engine is asked to operate on a masked unit. ESHUTDOWN is what is used for the similar case when the unit file enable/disable logic hits a masked unit file, hence is a natural candidate to be used here too. Background: before this patch both "job type not applicable" and "unit masked" where mapped to EBADR, which transaction_add_job_and_dependencies() then checked for. It actually wanted to check exclusively for the former error condition, not the latter but due to the same mapping this failed to work. This patch semi-undoes an accidental change made in caffa4ef700fdd0eadd6c0b2ef9925611672a1bc, however restores the error number to ESHUTDOWN instead of the original ENOSYS (for the reasons indicated above). To make this easier to grok for the future, I added comments to explaining which error conditions are checked for. Fixes: #2315

networkd: Add support to configure VXLAN Port
2016-01-26networkd: rework Domains= settingLennart Poettering
Previously, .network files only knew a vaguely defined "Domains=" concept, for which the documentation declared it was the "DNS domain" for the network connection, without specifying what that means. With this the Domains setting is reworked, so that there are now "routing" domains and "search" domains. The former are to be used by resolved to route DNS request to specific network interfaces, the latter is to be used for searching single-label hostnames with (in addition to being used for routing). Both settings are configured in the "Domains=" setting. Normal domain names listed in it are now considered search domains (for compatibility with existing setups), while those prefixed with "~" are considered routing domains only. To route all lookups to a specific interface the routing domain "." may be used, referring to the root domain. An alternative syntax for this is the "*", as was already implemented before using the "wildcard" domain concept. This commit adds proper parsers for this new logic, and exposes this via the sd-network API. This information is not used by resolved yet, this will be added in a later commit.

2016-01-19resolved: add bus API for configuring per-link DNS settingsLennart Poettering
This is useful for alternative network management solutions (such as NetworkManager) to push DNS configuration data into resolved. The calls will fail should networkd already have taken possesion of a link, so that the bus API is only available if we don't get the data from networkd.

2016-01-18bus-kernel: reword assignment of dst_id in bus_message_setup_kmsgZbigniew Jędrzejewski-Szmek
Setting of dst_id was based on interplay of two booleans, making the logic hard to follow (for humans and compilers alike). gcc was confused and emmitted a warning about an uninitialized variable. Rework the code to make it obvious that dst_id is set properly.

2016-01-18sd-event: check clock argument to sd_event_now()Zbigniew Jędrzejewski-Szmek
sd_event_now() is a public function, so we must check all arguments for validity. Update man page and add tests. Sample debug message: Assertion 'IN_SET(clock, CLOCK_REALTIME, CLOCK_REALTIME_ALARM, CLOCK_MONOTONIC, CLOCK_BOOTTIME, CLOCK_BOOTTIME_ALARM)' failed at src/libsystemd/sd-event/sd-event.c:2719, function sd_event_now(). Ignoring.
2016-01-18bus-error: verify additional error maps during installationZbigniew Jędrzejewski-Szmek
Go over the entries in the map and check that they make sense. Tests are added. In the future we might want to do additional checks, e.g. verifying that the error names are in the expected format.
2016-01-18basic,bus-error: return negative error from errno_from_nameZbigniew Jędrzejewski-Szmek
errno_from_name used an unusual return convention where 0 meant "not found". This tripped up config_parse_syscall_errno(), which would treat that as success. Return -EINVAL instead, and adjust bus_error_name_to_errno() for the new convention. Also remove a goto which was used as a simple if and clean up surroudning code a bit.
2016-01-13tree-wide: check if errno is greater than zero (2)Zbigniew Jędrzejewski-Szmek
Compare errno with zero in a way that tells gcc that (if the condition is true) errno is positive.

sd-event: instrument sd_event_run() for profiling delays
2016-01-12sd-event: instrument sd_event_run() for profiling delaysVito Caputo
Set SD_EVENT_PROFILE_DELAYS to activate accounting and periodic logging of the distribution of delays between sd_event_run() calls. Time spent in dispatching as well as time spent outside of sd_event_run() is measured and accounted for. Every 5 seconds a logarithmic histogram loop iteration delays since 5 seconds previous is logged. This is useful in identifying the frequency and magnitude of latencies affecting the event loop, which should be kept to a minimum.

2016-01-11resolved: don't attempt to send queries for DNSSEC RR types to servers not ↵Lennart Poettering
supporting them If we already degraded the feature level below DO don't bother with sending requests for DS, DNSKEY, RRSIG, NSEC, NSEC3 or NSEC3PARAM RRs. After all, we cannot do DNSSEC validation then anyway, and we better not press a legacy server like this with such modern concepts. This also has the benefit that when we try to validate a response we received using DNSSEC, and we detect a limited server support level while doing so, all further auxiliary DNSSEC queries will fail right-away.
