* Always load CA, key and certificate files at the time the configurationjsing2016-07-063-35/+72
| | | | | | | | | | function is called. This simplifies code and results in a single memory based code path being used to provide data to libssl. Errors that occur when accessing the specified file are now detected and propagated immediately. Since the file access now occurs when the configuration function is called, we now play nicely with privsep/pledge. ok beck@ bluhm@ doug@

| | | | | | | | | | | | | | BN_mod_word() can return incorrect results if the supplied modulus is too big, so we need to fall back to BN_div_word. Now that BN_mod_word may fail, handle errors properly update the man page. Thanks to Brian Smith for pointing out these fixes from BoringSSL: https://boringssl.googlesource.com/boringssl/+/67cb49d045f04973ddba0f92fe8a8ad483c7da89 https://boringssl.googlesource.com/boringssl/+/44bedc348d9491e63c7ed1438db100a4b8a830be ok beck@

* Tighten behavior of _rs_allocate failure for portable arc4random ↵bcook2016-06-3014-14/+28
| | | | | | | | | | implementations. In the event of a failure in _rs_allocate for rsx, we still have a reference to freed memory for rs on return. Not a huge deal since we subsequently abort in _rs_init, but it looks strange on its own. ok deraadt@
* Tighten behavior of _rs_allocate on Windows.bcook2016-06-302-8/+14
| | | | | | | | | | | | For Windows, we are simply using calloc, which has two annoyances: the memory has more permissions than needed by default, and it comes from the process heap, which looks like a memory leak since this memory is rightfully never freed. This switches _rs_alloc on Windows to use VirtualAlloc, which restricts the memory to READ|WRITE and keeps the memory out of the process heap. ok deraadt@

| | | | | | | | This removes support for DSA_FLAG_NO_EXP_CONSTTIME, DH_FLAG_NO_EXP_CONSTTIME, and RSA_FLAG_NO_CONSTTIME flags, making all of these operations unconditionally constant-time. Based on the original patch by César Pereid. ok beck@
