2014-08-24Fix waitpid EINTR error on SIGCHLDMatthias Schiffer
waitpid may fail with EINTR for SIGCHLD even when all signals are blocked.
2014-08-24Merge peer config into peer structureMatthias Schiffer
With this refactoring, the structure fastd_peer_config_t is merged into fastd_peer_t, and fastd_remote_config_t into fastd_remote_t. This also means we now create peers directly when reading their configurations, which significantly simplifies the whole reload process, and prepares for some future optimizations like a key hash table. Note: This commit is too big, but I couldn't come up with a nice way to split it into smaller pieces...
2014-08-22Remove VECTOR_ALLOCMatthias Schiffer
It is done automatically now if the VECTOR is zeroed before.
2014-08-19Create peer structures for disabled peers as wellMatthias Schiffer
We have a 1:1 association between peers and peer configs now.
2014-08-18Unify enabled and dynamic flags into a config_state flagMatthias Schiffer
2014-08-18Rename WITH_VERIFY CMake option to WITH_DYNAMIC_PEERSMatthias Schiffer
2014-08-18peer: add a flag `dynamic' instead of checking the config field for NULLMatthias Schiffer
2014-08-18Rename "temporary peers" to "dynamic peers"Matthias Schiffer
2014-08-09Move fastd_config_t.peers to fastd_context_t.peer_configsMatthias Schiffer
2014-08-02Encapsulate semaphore handlingMatthias Schiffer
2014-08-02Introduce and use alloc helpersMatthias Schiffer
These new helpers will terminate fastd on allocation failures and add some additional convenience (allow strdup with NULL; typesafe new(type) macros).
2014-08-01Use srandom/random instead of rand_rMatthias Schiffer
There's no need to keep our own seed.

2014-05-31Fix dump_state()Matthias Schiffer
2014-05-31Fix poll race condition on *BSDMatthias Schiffer
2014-05-31More signal handling fixesMatthias Schiffer
2014-05-31Fix blocking signals...Matthias Schiffer
2014-05-31Remove EINTR handling where signals are blocked anywaysMatthias Schiffer
2014-05-31Unblock signals only during poll/epoll waitMatthias Schiffer
If signals are normally blocked, we can avoid a lot of EINTR handling.
2014-05-31Make log levels verbose and info more usefulMatthias Schiffer
2014-05-31Split main functionMatthias Schiffer
init() is still a bit long, but much better than before.
2014-05-31Fix signal handling racesMatthias Schiffer
2014-05-29Document *everything*Matthias Schiffer
2014-05-29Simplify configuration of cipher and MAC implementationsMatthias Schiffer
Let the cipher and MAC handlers just store the chosen implementations themselves instead of relying on the global configuration.
2014-05-25Unify fastd_peer_group_t and fastd_peer_group_config_t into a single structureMatthias Schiffer
2014-05-25Completely document fastd.hMatthias Schiffer
2014-05-25Make a few struct fields that are not supposed to be changed defines insteadMatthias Schiffer

2014-05-23Revert "Fix waitpid race condition"Matthias Schiffer
This reverts commit 47d84679d6fe71f56d3a013578007dff92ff72db.
2014-05-22Clean up fastd.c includesMatthias Schiffer
2014-05-22Move fastd_handle_receive() to receive.cMatthias Schiffer
2014-05-22Fix waitpid race conditionMatthias Schiffer
Doing a waitpid for all processes in the SIGCHLD handler could sometimes steal a signal from a fastd_shell_command_exec_sync call. To fix this, don't reap the children in the SIGCHLD handler anymore, but create a reaper thread for each asynchronous shell command.
2014-05-05Make systemd support optional againMatthias Schiffer
2014-05-01Remove support for log filesMatthias Schiffer
syslog/journald do a much better job at organizing logs, with the additional advantage of proper log rotation. If someone really wants to have a log file for fastd, they can just redirect stderr.
2014-04-30Remove now unneeded FD_CLOEXEC flag configMatthias Schiffer
2014-04-30shell: close all fds > 2 after forkingMatthias Schiffer
socket/fcntl to set FD_CLOEXEC isn't thread-safe with async verify handlers, and SOCK_CLOEXEC isn't portable.

fastd_setfd and move to fastd.h

2014-04-26Revise shell command APIMatthias Schiffer
2014-04-25Move around some codeMatthias Schiffer
2014-04-25Remove ref-counting on remotesMatthias Schiffer
Now that peers have a peer id we can use that to specify a peer in a resolve return. As the remote list of a peer doesn't change without the peer id changing, instead of taking a remote ref we can just use the peer id and remote index.

established peers
2014-04-24Always use size_t for countersMatthias Schiffer
2014-04-23Use socketpair instead of pipe for internal message pipesMatthias Schiffer
While pipe2 recently got O_DIRECT on Linux, we'll just use SOCK_DGRAM to stay portable, and get proper handling of full queues.
2014-04-21Remove vector of new temporary peersMatthias Schiffer
The new poll code has made this second peer list obsolete.
