* Refactor the async wait fd logicMatt Caswell2016-02-298-137/+266
| | | | | | | | | | | | | | | | | | | Implementation experience has shown that the original plan for async wait fds was too simplistic. Originally the async logic created a pipe internally and user/engine code could then get access to it via API calls. It is more flexible if the engine is able to create its own fd and provide it to the async code. Another issue is that there can be a lot of churn in the fd value within the context of (say) a single SSL connection leading to continually adding and removing fds from (say) epoll. It is better if we can provide some stability of the fd value across a whole SSL connection. This is problematic because an engine has no concept of an SSL connection. This commit refactors things to introduce an ASYNC_WAIT_CTX which acts as a proxy for an SSL connection down at the engine layer. Reviewed-by: Richard Levitte <levitte@openssl.org>
* Always build library object files with shared library cflagsRichard Levitte2016-02-201-1/+1
| | | | | | | | | | | | | | | | This takes us away from the idea that we know exactly how our static libraries are going to get used. Instead, we make them available to build shareable things with, be it other shared libraries or DSOs. On the other hand, we also have greater control of when the shared library cflags. They will never be used with object files meant got binaries, such as apps/openssl or test/test*. With unified, we take this a bit further and prepare for having to deal with extra cflags specifically to be used with DSOs (dynamic engines), libraries and binaries (applications).

* Remove all special make depend flags, as well as OPENSSL_DOING_MAKEDEPENDRichard Levitte2016-02-181-1/+1
| | | | | | | | | | All those flags existed because we had all the dependencies versioned in the repository, and wanted to have it be consistent, no matter what the local configuration was. Now that the dependencies are gone from the versioned Makefile.ins, it makes much more sense to use the exact same flags as when compiling the object files. Reviewed-by: Rich Salz <rsalz@openssl.org>

* Rename INSTALL_PREFIX to DESTDIR, remove option --install_prefixRichard Levitte2016-02-121-2/+2
| | | | | | | | | | | | | INSTALL_PREFIX is a confusing name, as there's also --prefix. Instead, tag along with the rest of the open source world and adopt the Makefile variable DESTDIR to designate the desired staging directory. The Configure option --install_prefix is removed, the only way to designate a staging directory is with the Makefile variable (this is also implemented for VMS' descrip.mms et al).

* Attempt to log an error if init failedMatt Caswell2016-02-101-2/+0
| | | | | | | | | If init failed we'd like to set an error code to indicate that. But if init failed then when the error system tries to load its strings its going to fail again. We could get into an infinite loop. Therefore we just set a single error the first time around. After that no error is set. Reviewed-by: Rich Salz <rsalz@openssl.org>

* Async error handling and MacOS/X fixesViktor Dukhovni2015-11-227-50/+50
| | | | | | | | | | | | | | | | | | | In the async code for MacOS/X define _XOPEN_SOURCE (if not already defined) as early as possible. We must do this before including any header files, because on MacOS/X <stlib.h> includes <signal.h> which includes <ucontext.h>. If we delay defining _XOPEN_SOURCE and include <ucontext.h> after various system headers are included, we are very likely to end up with the wrong (truncated) definition of ucontext_t. Also, better error handling and some code cleanup in POSIX fibre construction and destruction. We make sure that async_fibre_makecontext() always initializes the fibre to a state that can be freed. For all implementations, check for error returns from async_fibre_makecontext(). Reviewed-by: Matt Caswell <matt@openssl.org>

* Swap to using proper windows pipesMatt Caswell2015-11-205-21/+25
| | | | | | | | | | We were using _pipe to create a pipe on windows. This uses the "int" type for its file descriptor for compatibility. However most windows functions expect to use a "HANDLE".

It should be the other way around because the getcontext call may overwrite some of the things we just initialised. This didn't cause an issue on Linux and so the problem went unnoticed.
