* add support for building libtlsBrent Cook2014-12-061-1/+7
| | | | | | | | Use './configure --enable-libtls' to build the library and install the associated manpages. Note that the API and ABI of this library may change still, though feedback is welcome. ok deraadt@ jsing@ tedu@
* add minimal poll(2) implementation for WindowsBrent Cook2014-12-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides sufficient functionality to run openssl(1) from a Windows console. This is based on the original select-based version from from songdongsheng@live.cn. Changes: * use nfds_t directly for iterating the fds. * add WSAGetLastError -> errno mappings * handle POLLHUP and the OOB data cases for revents * handle sparse arrays of fds correctly * KNF style updates * teach poll how to handle file handles as well as sockets This handles the socket/non-socket issue by alternating a loop between WaitForMultipleObjects for non-sockets and and select for sockets. One would think this would be terrible for performance, but as of this writing, poll consumes about 6% of the time doing a bulk transfer between a Linux box and 'openssl.exe s_server'. I tried to implement this all in terms of WaitForMultipleObjects with a select 'poll' at the end to get extra specific socket status. However, the cost of setting up an event handle for each socket, setting the WSAEventSelect attributes, and cleaning them up reliably was pretty high. Since the event handle associated with a socket is also global, creating a new one cancels the previous one or can be disabled externally. In addition, the 'FD_WRITE' status of a socket event handle does not behave in an expected fashion, being triggered by an edge on a write event rather than being level triggered. Another fun horror story is how stdin in windows might be a console, it might be a pipe, it might be something else. If these all worked in the same way, it would be great. But, since a console-stdin can also signal on a mouse or window event, it means we can easily get stuck in a blocking read (you can't make stdin non-blocking) if the non-character events are not filtered out. So, poll does that too. See here for various additional horror stories: http://www.postgresql.org/message-id/4351.1336927207@sss.pgh.pa.us

* Quiet clang warnings about unused arguments in general.Brent Cook2014-11-031-1/+13
| | | | | Check if we are using clang, rather than simply if we are on OS X. Note: recent LLVM releases do not seem to need this anyway.
* make 'autoreconf' work from dist tarballBrent Cook2014-11-031-1/+1
| | | | We need to include VERSION for it to run.
* override native arc4random_buf on FreeBSDBrent Cook2014-11-031-1/+6
| | | | | | | | | | | | | | | | The FreeBSD-native arc4random_buf implementation falls back to weak sources of entropy if the sysctl fails. Remove these dangerous fallbacks by overriding locally. Unfortunately, pthread_atfork() is broken on FreeBSD (at least 9 and 10) if a program does not link to -lthr. Callbacks registered with pthread_atfork() simply fail silently. So, it is not always possible to detect a PID wraparound. I wish we could do better. This improves arc4random_buf's safety compared to the native FreeBSD implementation. Tested on FreeBSD 9 and 10. ok beck@ deraadt@
* override native arc4random_buf on OS XBrent Cook2014-11-031-0/+4
| | | | | | | | While the native OS X implementation is fork-safe, it does not seed safely, as of the latest released OS X libc sources, version 997.90.3. It only uses weak sources of entropy if accessing /dev/urandom fails. ok beck@ deraadt@
* Improve and simplify function and header detection logic.Brent Cook2014-10-301-76/+21
| | | | | | | | | Simplify autoconf checks by using AC_CHECK_FUNCS/HEADERS. Clarify some ambiguous dependencies around strnlen/strndup. Unconditionally enable pidwraptest for all arc4random implementations. Remove HAVE_VASPRINTF conditional, since asprintf requires vasprintf. ok @doug
* use the correct HOST_OS for the Windows buildBrent Cook2014-10-301-1/+1
| | | | ok doug@
* set various glibc flags that also are useful with mingwBrent Cook2014-10-221-1/+2
| | | | for example, asprintf/vasprintf are unmasked with _GNU_SOURCE in mingw
* include a proper check for memmem when configuring unit testsBrent Cook2014-10-221-0/+5
| | | | This allows the proper compatibility header definition to be exposed.
* ensure compatibility with posix shellBrent Cook2014-08-181-1/+1
| | | | remove bash comparison, thanks kinichiro
* add --disable-asm flag for disabling inline asmBrent Cook2014-08-171-0/+4
| | | | | Surprisingly (or not), a lot of OpenSSL's inline assembly actually makes things slower with a relatively modern compiler (read, gcc >= 4.x).
* allow inline asmBrent Cook2014-08-161-1/+1
| | | | use default of -std=gnu99 for it to be recognized
* set _DEFAULT_SOURCE on linux hostsBrent Cook2014-08-161-1/+1
| | | | this is the replacement for _BSD_SOURCE on newer glibc's
