* Expose EOF without close-notify via tls_close().jsing2015-09-142-6/+14
| | | | | | | | | | | Make tls_read(3)/tls_write(3) follow read(2)/write(2) like semantics and return 0 on EOF with and without close-notify. However, if we saw an EOF from the underlying file descriptors without getting a close-notify, save this and make it visible when tls_close(3) is called. This keeps the semantics we want, but makes it possible to detect truncation at higher layers, if necessary. ok beck@ guenther@

| | | | | | | | MD4 should have been removed a long time ago. Also, RFC 6150 moved it to historic in 2011. Rides the major crank from removing SHA-0. Discussed with many including beck@, millert@, djm@, sthen@ ok jsing@, input + ok bcook@

| | | | | OPENSSL_ia32cap_loc; nothing in ports uses them besides embedded copies of OpenSSL. This opens the `all hell gets loose' window.

* Stop generating private keys in a network buffer.jsing2015-09-132-58/+58
| | | | | | | | | | The current client key exchange code generates DH and ECDH keys into the same buffer that we use to send data to the network - stop doing this and malloc() a new buffer, which we explicit_bzero() and free() on return. This also benefits from ASLR and means that the keys are no longer generated in a well known location. ok beck@

* Factor out setup_up / destroy_ui functions.bcook2015-09-134-58/+58
| | | | | | | | | This pulls out and renames setup_ui/destroy_ui so we have something that can be replaced as-needed, moving the the console setup code for Windows to app_win.c in -portable, instead of needing a local patch to enable binary console mode ui_read/write are also simplified.

* Check ECDH output buffer length and avoid truncation.jsing2015-09-136-12/+32
| | | | | | | | | Currently, if you call ECDH_compute_key() it will silently truncate the resulting key if the output buffer is less than the key size. Instead, detect this condition and return an error. If the buffer provided is larger than the key length, zero the remainder. ok beck@ miod@ "+ shivers"

| | | | | | | | | | | | | cpu's specific hardware capabilities users of libcrypto might be interested in, as an integer value. This deprecates the existing OPENSSL_ia32cap() macro and the OPENSSL_ia32cap_loc() function (which returns the pointer so that you can mess with stuff you shouldn't mess with). Interpreting the value returned by OPENSSL_cpu_caps() is, of course, machine-dependent. Minor version bump for libcrypto. ok beck@ jsing@
