2015-07-23resolve: drop dns_scope_good_dns_server()Lennart Poettering
It's not used anymore since 29815b6c608b836cada5e349d06a96b63eaa65f3, hence let's remove it from the sources.
2015-07-14resolved: use one UDP socket per transactionTom Gundersen
We used to have one global socket, use one per transaction instead. This has the side-effect of giving us a random UDP port per transaction, and hence increasing the entropy and making cache poisoining significantly harder to achieve. We still reuse the same port number for packets belonging to the same transaction (resent packets).
2015-07-14resolved: pin the server used in a transactionTom Gundersen
We want to discover information about the server and use that in when crafting packets to be resent.
2015-07-14resolved: packet - ensure there is space for IP+UDP headersTom Gundersen
Currently we only make sure our links can handle the size of the payload witohut taking the headers into account.
2015-07-13resolved: separate LLMNR specific header bitsDaniel Mack
The C and T bits in the DNS packet header definitions are specific to LLMNR. In regular DNS, they are called AA and RD instead. Reflect that by calling the macros accordingly, and alias LLMNR specific macros. While at it, define RA, AD and CD getters as well.
2015-07-13resolved: use a #define for LLMNR portDaniel Mack
De-duplicate some magic numbers.
2015-07-13resolved: move LLMNR related functions into separate fileDaniel Mack
2015-06-10resolve: move dns routines into sharedNick Owens
2015-05-18util: split all hostname related calls into hostname-util.cLennart Poettering
2015-04-11shared: add random-util.[ch]Ronny Chevalier
2015-03-13Use space after a silencing (void)Zbigniew Jędrzejewski-Szmek
We were using a space more often than not, and this way is codified in CODING_STYLE.
2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
2014-12-11networkd/resolved: correct spacing near eol in code commentsTorstein Husebø
2014-12-03resolved: don't resolve the hostname "gateway" with LLMNR, leave that to ↵Lennart Poettering
nss-myhostname
2014-11-28treewide: yet more log_*_errno + return simplificationsMichal Schmidt
Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().

2014-10-23resolve: make DnsScope::conflict_queue an OrderedHashmapMichal Schmidt
on_conflict_dispatch() uses hashmap_steal_first() and then does something non-trivial with it. It may care about the order.
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.
2014-08-15resolved: fix assertion when joining llmnr mcast groupLennart Poettering
2014-08-14resolved: clarify that LLMNR scopes must have a link assignedLennart Poettering
This is supposed to remove some compiler warnings: http://lists.freedesktop.org/archives/systemd-devel/2014-July/021393.html
2014-08-14resolved: allow passing on which protocol, family and interface to look ↵Lennart Poettering
something up Also, return on which protocol/family/interface we found something.

2014-08-05resolved: never reuse transactions for probing that are already completed ↵Lennart Poettering
based on cached data
2014-08-03resolved: avoid possible dereference of null pointerThomas Hindoe Paaboel Andersen
In dns_scope_make_reply_packet the structs q, answer, and soa can be null. We should check for null before reading their fields.
2014-08-01resolved: always drop multicast membership before adding oneLennart Poettering
This is apparently necessary on some devices, such as veth.
2014-08-01resolved: flush cache each time we change to a different DNS serverLennart Poettering
2014-08-01resolved: beef up DNS server configuration logicLennart Poettering
We now maintain two lists of DNS servers: system servers and fallback servers. system servers are used in combination with any per-link servers. fallback servers are only used if there are no system servers or per-link servers configured. The system server list is supposed to be populated from a foreign tool's /etc/resolv.conf (not implemented yet). Also adds a configuration switch for LLMNR, that allows configuring whether LLMNR shall be used simply for resolving or also for responding.

2014-07-30resolved: don't attempt to order empty answer arrayLennart Poettering

addresses are link-local or not
2014-07-29resolved: the llmnr destination address check applies to queries, not to ↵Lennart Poettering

2014-07-29resolve: add llmnr responder side for UDP and TCPLennart Poettering
Name defending is still missing.
2014-07-23resolved: rework logic so that we can share transactions between queries of ↵Lennart Poettering
different clients
2014-07-18resolved: do not use unitialized variableZbigniew Jędrzejewski-Szmek
2014-07-18in-addr-util: remove family_to_string() APILennart Poettering
we already have a more complete one with af_to_name(), that is generated from the header files, no need to duplicate this.
2014-07-18change type for address family to "int"Lennart Poettering
Let's settle on a single type for all address family values, even if UNIX is very inconsitent on the precise type otherwise. Given that socket() is the primary entrypoint for the sockets API, and that uses "int", and "int" is relatively simple and generic, we settle on "int" for this.
