2015-08-05hostname-util: add relax parameter to hostname_is_validZbigniew Jędrzejewski-Szmek
Tests are modified to check behaviour with relax and without relax. New tests are added for hostname_cleanup(). Tests are moved a new file (test-hostname-util) because there's now a bunch of them. New parameter is not used anywhere, except in tests, so there should be no observable change.

Follow-up for PR #877.

2015-08-05networkd: serialize the private optionsAlex Crawford
Save the private options along side the rest of the options in the lease files.
2015-08-05networkd: add private options to lease structAlex Crawford
This stores private-zone DHCP options inside of their respective DHCP lease. These options aren't used by networkd (what would it do with them?), but saving them will allow other programs to query the values. To improve performance, the options are stored in ascending order by tag.

2015-08-03tree-wide: convert bootchart and lldp code to use clock_boottime_or_monotonic()Lennart Poettering
We should avoid using CLOCK_BOOTTIME directly unless we actually can sensible distuingish it from CLOCK_MONOTONIC. CLOCK_BOOTTIME is only fully feature on very recent Linux kernels, hence we should stick to a fallback logic, which is already available in the clock_boottime_or_monotonic() call.
2015-08-03sd-event: make sure sd_event_now() cannot failLennart Poettering
Previously, if the event loop never ran before sd_event_now() would fail. With this change it will instead fall back to invoking now(). This way, the function cannot fail anymore, except for programming error when invoking it with wrong parameters. This takes into account the fact that many callers did not handle the error condition correctly, and if the callers did, then they kept simply invoking now() as fall back on their own. Hence let's shorten the code using this call, and make things more robust, and let's just fall back to now() internally. Whether now() is used or the cache timestamp may still be detected via the return value of sd_event_now(). If > 0 is returned, then the fall back to now() was used, if == 0 is returned, then the cached value was returned. This patch also simplifies many of the invocations of sd_event_now(): the manual fall back to now() can be removed. Also, in cases where the call is invoked withing void functions we can now protect the invocation via assert_se(), acknowledging the fact that the call cannot fail anymore except for programming errors with the parameters. This change is inspired by #841.
2015-07-29tree-wide: port everything over to fflush_and_check()Lennart Poettering
Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.
2015-07-14Merge pull request #538 from mischief/multiple-routersTom Gundersen
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.
2015-07-12dhcp: 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 - 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.
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.

2015-03-04sd-dhcp6-client: delay setting the DUID and don't fail constructorThomas Haller
sd_dhcp6_client_new() tried to set the DUID based on the machine id. If the host has no /etc/machine-id, the constructor would fail making it impossible to create an sd_dhcp6_client instance. Relax this and create a DUID only later as needed. This way a caller caller can workaround a missing machine-id file and set a DUID of his choosing via sd_dhcp6_client_set_duid().

The test would treat the first non-empty set of matches in match_paths, match_drivers, match_types, match_names as definitive (essentially chaining them with OR). Make those tests instead match like other tests and require all to pass if the set of patterns is nonempty.
