* networkd: rework warning and debug messages about address addition and removalZbigniew Jędrzejewski-Szmek2019-06-241-34/+34
| | | | | | | | | | | | | | Those messages were quite confusing. In particular "adding address" suggests that we are assiging a new address to an interface, but in fact we're just reacting to a notification about an addition. So let's call that "remembering" and "forgetting". It's not fully gramatically correct, but I think it's much clearer than "adding"/"removing" in this context. And "received address without address" is too cryptic, let's say "address message" to distinguish the message from its content. Also, make failure to format address non-fatal, and print more details in various places.

* network: fix use-after-freeYu Watanabe2019-05-071-13/+29
| | | | | | | The function sd_radv_add_prefix() in dhcp6_pd_prefix_assign() may return -EEXIST, and in that case the sd_radv_prefix object allocated in dhcp6_pd_prefix_assign() will be freed when the function returns. Hence, the key value in Manager::dhcp6_prefixes hashmap is lost.

* network: fix ref/unref logic for Link objectYu Watanabe2019-04-251-4/+3

* Make fopen_temporary and fopen_temporary_label unlockedZbigniew Jędrzejewski-Szmek2019-04-121-2/+0
| | | | | | | | This is partially a refactoring, but also makes many more places use unlocked operations implicitly, i.e. all users of fopen_temporary(). AFAICT, the uses are always for short-lived files which are not shared externally, and are just used within the same context. Locking is not necessary.
* headers: remove unneeded includes from util.hZbigniew Jędrzejewski-Szmek2019-03-271-0/+1
| | | | | This means we need to include many more headers in various files that simply included util.h before, but it seems cleaner to do it this way.

|\ | | | | Store domains lists in OrderedSets in networkd
| * networkd: use OrderedSets instead of strvs to store lists of domainsZbigniew Jędrzejewski-Szmek2019-02-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | We were already using OrderedSets in the manager object, but strvs in the configuration parsing code. Using sets gives us better scaling when many domains are used. In oss-fuzz #13059 the attached reproducer takes approximately 30.5 s to be parsed. Converting to sets makes this go down to 10s. This is not _vastly_ faster, but using sets seems like a nicer approach anyway. In particular, we avoid the quadratic de-unification operation after each addition.

* | dhcp: move filtering of bogus DNS/NTP addresses out of DHCP clientThomas Haller2019-02-181-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The DHCP client should not pre-filter addresses beyond what RFC requires. If a client's user (like networkd) wishes to skip/filter certain addresses, it's their responsibility. The point of this is that the DHCP library does not hide/abstract information that might be relevant for certain users. For example, NetworkManager exposes DHCP options in its API. When doing that, the options should be close to the actual lease. This is related to commit d9ec2e632df4905201facf76d6a205edc952116a (dhcp4: filter bogus DNS/NTP server addresses silently).
