2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.

2015-01-23resolved: when rereading /etc/resolv.conf, always start using first DNS ↵Lennart Poettering
server again Previously we tried to stick to a DNS server as long as it is available. When /etc/resolv.conf changed, and the old DNS server we used was still in there we'd continue to use it, even if it was at the end of the list. With this change we'll now always start with the first DNS server in the list again. Rationale: certain network managing implementations (notably NetworkManager) when connected to a VPN place both the VPN DNS server as well as the local DNS server in /etc/resolv.conf. If we used the local one before we would thus continue to use the local one, making VPN names unresolvable. NetworkManager really should be fixed to only place the VPN DNS servers in the file, but with this commit things are at least similarly bad as they used to be...

2014-12-01resolved: make TXT RR generation and parsing more in-line with RFC 6763, ↵Lennart Poettering
section 6.1 The RFC says to encode an single empty TXT string instead of an empty TXT array. It also says to treat a zero-length TXT RR as a TXT array with a single zero-length string.

2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28treewide: a few more log_*_errno + return simplificationsMichal Schmidt
The one in tmpfiles.c:create_item() even looks like it fixes a bug.
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().
2014-11-27resolve: 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!

2014-10-22resolved: 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.

2014-09-15hashmap: 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.

2014-08-22shared: 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.

LLVM+clang does not allow statement-expressions inside of type-declarations (file-scope). Use CONST_MAX() to avoid this.

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.
