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().
2014-11-27resolve: reject empty TXT recordsStanisław Pitucha
TXT records should have at least one character, so enforce this. Before 0f84a72 parser SIGSEGV'd on ->txt.strings being NULL, but even if this is fixed we should reject invalid TXT records.
2014-11-27resolve: set error code on failureStanisław Pitucha
Set the error code in case of incorrect name. This prevents continuing and failing an assert(name) later on.
2014-11-27resolve: fix redirection loops in compressed RRStanisław Pitucha
Loops in RR compression were only detected for the first entry. Multiple redirections should be allowed, each one checking for an infinite loop on its own starting point. Also update the pointer on each redirection to avoid longer loops of labels and redirections, in names like: (start) [len=1] "A", [ptr to start] (David: rename variable to "jump_barrier" and add reference to RFC)
2014-11-27resolve: fix NULL deref on strv comparisonDavid Herrmann
A strv might be NULL if it is empty. The txt.strings comparison doesn't take that into account. Introduce strv_equal() to provide a proper helper for this and fix resolve to use it. Thanks to Stanisław Pitucha <viraptor@gmail.com> for reporting this!
2014-11-25resolved: fix typo in sd_notify() callTom Gundersen
2014-11-17resolve: fix CID#1237549 Unchecked return valueSusant Sahani
2014-11-01resolved: dns-packet - use unaligned read/write helpersTom Gundersen
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.

2014-10-22resolved: simplify detection of packets from the loopback deviceLennart Poettering
We can simplify our code quite a bit if we explicitly check for the ifindex being 1 on Linux as a loopback check. Apparently, this is hardcoded on Linux on the kernel, and effectively exported to userspace via rtnl and such, hence we should be able to rely on it.

2014-10-13resolved: apply label to /run/systemd/resolve/resolv.confZbigniew Jędrzejewski-Szmek
Under an SELinux system, we want the file that is created to have a proper context, different from the default for files in /run. This is so that the policy can give access to almost everyone to this file.
2014-10-13resolved: split out writing of resolv.confZbigniew Jędrzejewski-Szmek
manager_write_resolv_conf() is quite long anyway.
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.
2014-09-13resolved: fall back to hardcoded ifindex when checking if a link is the loopbackTom Gundersen
Reported by Philippe De Swert <philippedeswert@gmail.com>. Coverity CID#1237656
2014-08-22resolved: fix typo in log messageLennart Poettering
2014-08-22shared: add MAXSIZE() and use it in resolvedDavid Herrmann
The MAXSIZE() macro takes two types and returns the size of the larger one. It is much simpler to use than MAX(sizeof(A), sizeof(B)) and also avoids any compiler-extensions, unlike CONST_MAX() and MAX() (which are needed to avoid evaluating arguments more than once). This was suggested by Daniele Nicolodi <daniele@grinta.net>. Also make resolved use this macro instead of CONST_MAX(). This enhances readability quite a bit.
2014-08-21notify: send STOPPING=1 from our daemonsLennart Poettering
2014-08-20resolved: write resolv.conf search - switch argumentsTom Gundersen
Found by Lukáš Nykrýn.
2014-08-20resolved: fix which return codes we checkLennart Poettering
Discovered by Lukas Nykryn
2014-08-20resolved-dns-rr: fix typoLukas Nykryn
a->rrsig.type_covered != a->rrsig.type_covered" is always false regardless of the values of its operands because those operands are identical.
2014-08-15resolve: fix compilation on LLVM+clangDavid Herrmann
LLVM+clang does not allow statement-expressions inside of type-declarations (file-scope). Use CONST_MAX() to avoid this.
2014-08-15resolved: fix assertion when joining llmnr mcast groupLennart Poettering
2014-08-14resolved: pull in domain names from sd-networkTom Gundersen
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: enable LLMNRLennart Poettering
THis was accidentally broken, as we truned off LLMNR far to frequently, where we only wanted to turn off LLMNr on IPV6 on kernels lacking support for it.
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.
2014-08-13sd-network: /_get_link_/_link_get_/Tom Gundersen
The link is the 'object', so make this in line with our usual naming convention. Suggested by Kay and Lennart.

2014-08-11sd-network: rename the per-ifindex calls to sd_network_get_link_xxx()Lennart Poettering
This way we can introduce system-wide versions of these calls that are called the same way, but without the "link" in the name.
2014-08-11resolved: when picking a new hostname make sure two hosts pick different onesLennart Poettering
This way we can avoid always picking the same replacement hostnames when picking one.
