ECC certs should preferably use SHA2, this is what we want to be testing. Also assembling of all available test suites must consider TLS version.

The constant ?WORD_WIDTH is renamed ?BITS_IN_WORD, and a new constant ?BITS_IN_BYTE is introduced. Additionally, a bug in a currently unused case clause of llvm_type_from_size/1 is fixed (the size of a word was hardcoded to 64 bits).

2016-11-08Revert "Check libsctp for sctp funcs in configure.in"Raimo Niskanen
This reverts commit 52fae83743a6e84d719f4f82fe45e6e0efdbd6f0: Check libsctp for sctp funcs in configure.in Call AC_CHECK_LIB before calling AC_CHECK_FUNCS to check for functions in libsctp. Otherwise AC_CHECK_FUNCS will not link with libsctp to see if function exists. Reverting to the old behaviour of not checking for libsctp before checking for sctp functions. Then it works on Linux by loading libsctp and looking up the symbols i runtime, and it works on FreeBSD since there is no separate libsctp to link against - the functions are part of the default system libraries.

2016-11-07hipe_llvm: Work around LLVM 3.9 sdesc bugMagnus Lång
As of LLVM 3.9, the x86-call-frame-opt pass in LLVM's X86 backend causes the stack descriptors to contain incorrect (or even negative) frame sizes or root slot offsets. This might cause LLVM-compiled modules to be rejected during loading with a badarg exception in hipe_bifs:enter_sdecs/1 (which additionally prints a "hipe_bifs_enter_sdesc_1: bad sdesc!" message to stderr), or it might cause corruption or segmentation faults when walking stacks (f.ex. during GC) containing frames compiled with ErLLVM. As a workaround, we pass the -no-x86-call-frame-opt flag to llc when the version is at least 3.9
2016-11-07hipe_llvm: Fix incorrect atom alignment assumptionMagnus Lång
ErLLVM was declaring atoms in the following manner: @atom_ok = external constant i64 ; Used inside a function like this %var = ptrtoint i64* @atom_ok to i64 However, doing so makes LLVM think the `atom_ok` is 8-byte aligned, since it refers to a i64 value. This resulted in LLVM occasionally incorrectly optimising away type tests on atoms, causing incorrect behaviour or even segfaults. One such case is in bs_match_compiler:coverage_apply/2, in which an is_boxed test on a literal atom was optimised away, causing the code to try and load the "header" of an atom. This problem reproduces with LLVM versions 3.7 through 3.9. By declaring atoms as i8 (byte) constants instead, LLVM no longer makes these alignment assumptions, and the bug is fixed.

2016-11-05Fix performance bug in erl_prim_loader:get_modules/{2,3}Björn Gustavsson
The erl_prim_loader:get_modules/{2,3} functions were introduced in cd283583f8. Unfortunately, while the functions worked correctly, there was a bug in that many garbage maessages would be sent to the erl_prim_loader process. The number of extra messages depended on both the length of the code path and of the number of modules that were fetched. The messages were ignored and ultimately discarded, causing no harm except for a performance degradation and increase of the heap size for the erl_prim_loader process. The following functions were hit by the performance bug: code:atomic_load/1 code:ensure_modules_loaded/1 code:prepare_loading/1

2016-11-03Fix the native code translation of bs_match_stringKostis Sagonas
This fixes a HiPE bug reported on erlang-questions on 2/11/2016. The BEAM to ICode tranaslation of the bs_match_string instruction, written long ago for binaries (i.e., with byte-sized strings), tried to do a `clever' translation of even bit-sized strings using a HiPE primop that took a `Size' argument expressed in *bytes*. ICode is not really the place to do such a thing, and moreover there is really no reason for the HiPE primop not to take a Size argument expressed in *bits* instead. This commit changes the `Size' argument to be in bits, postpones the translation of the bs_match_string primop Fixed in a pair-programming/debugging session with @margnus1. until RTL and does a proper translation using bit-sized quantities there.

2016-11-02Add ECC curve selection order config in TLS serverFred Hebert
As per RFC 4492 Sec 5.1, the preferred order of selection of named curves is based on client preferences. Currently, the SSL application only picks entries according to the absolute order of entries as tracked in a hardcoded list in code. This patch changes things so that the client-specified order is preferred. It also allows a mode where the server can be configured to override the client's preferred order with its own, although the chosen ECC must still be within both lists. The configuration is done through the following options: - `eccs`, shared by clients and servers alike, allows the specification of the supported named curves, in their preferred order, and may eventually support more values for explicit primes and so on. - `honor_ecc_order`, a server-only option, is similar to `honor_cipher_order` and will, by default let the server pick the client-preferred ECC, and otherwise pick the server-preferred one. The default value for `eccs` is the same as before, although the server-chosen ECC now defaults to the client rather than previous choice. A function `ssl:eccs()` has been added that returns the highest supported ECCs for the library.
