* revert change to call kevent immediately.tedu2015-12-251-6/+65
| | | | | | | | | tcpbench (at a minimum) relies on the old behavior of changes all happening after all event handlers run. in particular, it resets the event for the listening socket *before* calling accept(), when it is still readable. kevent then (correctly) says it is readable on the next go through the loop. silly, subtle, and stupid. problem reported by kettenis
* change the kqueue backend to call kevent() as events are added insteadtedu2015-12-161-65/+6
| | | | | | | | | | | | of deferring until the dispatch loop. kqueue support for various types of files and filesystems has been historically incomplete, and kevent handles this condition by returning an error. the libevent dispatch loop has no way to recover from this error and fails catastrophically, bringing down the entire process because one file went bad. now, instead of all that happending, event_add will return an error. the application can choose to handle or ignore this error, but at least the band will play on. ok nicm

* Apply commit e0e6958aa074a7714cd7c4aa779a1dfede3a03b1 from upstream.bluhm2015-01-061-14/+8
| | | | | | | | | | - Avoid deadlock when activating signals. Fixes bug 3048812. Based on patch by Nicholas Marriott. The deadlock was ultimately fixed in a different way (by disabling reinit - see event.c r1.25). Add it now for consistency but without the Windows compatibility code. Convert the fnctl() calls to SOCK_CLOEXEC | SOCK_NONBLOCK to simplify the code. OK nicm@

* Fix CVE-2014-6272 in Libevent 1.4 from upstream:bluhm2015-01-052-11/+25
| | | | | | | | | | | - https://github.com/libevent/libevent/commit/7b21c4eabf1f3946d3f63cce1319c490caab8ecf - For this fix, we need to make sure that passing too-large inputs to the evbuffer functions can't make us do bad things with the heap. On top of that do: - Update libevent version to 1.4.15-stable. - Use SIZE_MAX from limits.h instead of a private define. - Do not declare 'size_t need' twice to avoid a compiler warning. OK sthen

| | | | | | | | | | | | | | | evbuffer_foo functions do. reyk, nicm, jmc, and schwarze seem to support a manpage as a reasonable solution to this problem. im putting this in a separate manpage because i find they get too cumbersome when they get too big. ingo agrees (and suggests even this might be too big). the file is evbuffer_new.3 rather than evbuffer.3 because we document functions. ok reyk@ nicm@ jmc@ schwarze@ this is rough, everyone has tweaks coming.

* Libevent has compatibilty wrappers in evutil. OpenBSD does not usebluhm2014-10-311-3/+6

A version bump is not necessary as the library itself does not change. Bulk ports build done by landry@ had no fallout. OK nicm@ deraadt@
