* Sprinkle a few BTI instructions into the arm64 assembly files and passkettenis2023-04-052-1/+8
| | | | | | -mmark-bti-property to indicate those now have BTI support. ok jsing@, deraadt@
* Replace bn_sub_part_words() with bn_sub().jsing2023-02-221-2/+1
| | | | | | | | Now that bn_sub() handles word arrays with potentially different lengths, we no longer need bn_sub_part_words() - call bn_sub() instead. This allows us to entirely remove the unnecessarily complex bn_sub_part_words() code. ok tb@
* Enable s2n-bignum word_clz() on amd64.jsing2023-02-161-1/+2
| | | | | | | | | The BN_num_bits_word() function is a hot path, being called more than 80 million times during a libcrypto regress run. The word_clz() implementation uses five instructions to do the same as the generic code that uses more than 60 instructions. Discussed with tb@
* Remove the now empty bn_asm.c.jsing2023-01-316-11/+5
| | | | | | This rather misnamed file (bn_asm.c) previously contained the C code that was needed to build libcrypto bignum on platforms that did not have assembly implementations of the functions it contained.
* Remove sparc related files from libcrypto.jsing2023-01-312-181/+0
| | | | | | | | The sparc platform got retired a while back, however some parts remained hiding in libcrypto. Mop these up (along with the bn_arch.h that I introduced). Spotted by and ok tb@
* Use s2n-bignum assembly implementations for libcrypto bignum on amd64.jsing2023-01-291-2/+11
| | | | | | | This switches the core bignum assembly implementations from x86_64-gcc.c to s2n-bignum for amd64. ok miod@ tb@
* Provide an implementation of bn_sqr() that calls s2n-bignum's bignum_sqr().jsing2023-01-211-1/+6
| | | | ok tb@
* Replace BN_DIV3W with HAVE_BN_DIV_3_WORDS (in bn_arch.h).jsing2023-01-201-2/+1
| | | | ok tb@
* Remove non-visible and unused OPENSSL_wipe_cpu and OPENSSL_atomic_addmiod2023-01-175-124/+6
| | | | | | | interfaces, and remove empty assembly OPENSSL_cpuid_setup routines - the default empty C fallback will work as good. ok jsing@
* Remove unused Elliptic Curve code.jsing2023-01-144-19/+3
| | | | | | | | | | | | | For various reasons, the ecp_nistp* and ecp_nistz* code is unused. While ecp_nistp* was being compiled, it is disabled due to OPENSSL_NO_EC_NISTP_64_GCC_128 being defined. On the other hand, ecp_nistz* was not even being built. We will bring in new versions or alternative versions of such code, if we end up enabling it in the future. For now it is just causing complexity (and grep noise) while trying to improve the EC code. Discussed with tb@

| | | | | | | | temporarily force sparc64 libcrypto to be built --no-execute-only because perlasm is still putting tables (intended to be rodata) into text. This will help dynamic executables, but static executables won't be saved by this. But this is temporary because we hope the perlasm problem is fixed soon.

* Start disentangling armv7 and aarch64 codetb2022-03-237-2/+508
| | | | | | | | | arm_arch.h and armcap.c are shared between armv7 and aarch64 which results in an inscrutable #ifdef maze. Move copies of these files into arch/{arm,aarch64}/ with appropriate names and some trivial minor adjustments. ok deraadt inoguchi kettenis

* Pass "openbsd" instead of "openbsd-elf" as the "flavour" to the perl assemblermiod2015-09-111-2/+2
| | | | | machinery. OpenBSD has never been not ELF on amd64, and changing this will actually make -portable life slightly easier in the near future.
* Disable ENGINE_load_dynamic (dynamic engine support).bcook2015-06-1913-13/+0
| | | | | | | We do not build, test or ship any dynamic engines, so we can remove the dynamic engine loader as well. This leaves a stub initialization function in its place. ok beck@, reyk@, miod@
* In the neverending saga of enabling and disabling assembler code for shamiod2015-03-181-5/+1
| | | | | | | | | | | routines on hppa, the cause for sha512-parisc subtly misbehaving has been found: despite having fallback pa1.1 code when running on a 32-bit cpu, the shift constants used in the sigma computations in sha512 are >= 32 and are silently truncated to 5 bits by the assembler, so there is no chance of getting this code to work on a non-pa2.0 processor. However, the pa1.1 fallback code for sha256 is safe, as it never attempts to shift by more than 31, so reenable it again.
* Do not use sha512-parisc for now, as it is subtly bugged - passes the shamiod2015-03-051-1/+3
| | | | | | | | | | | regress tests but causes tls ciphersuite using sha386 to fail; found the hard way by henning@. I can't see anything wrong in the generated assembly code yet, but building a libcrypto with no assembler code but sha512_block_data_order() is enough to trigger Henning's issue, so the bug lies there. No ABI change; ok deraadt@

| | | | | bn_div_words, bn_mul_add_words, bn_mul_words, bn_sqr_words, bn_sub_words) on sgi, because the generated assembly code isn't R4000-safe.

* Add the Cammelia cipher to libcrypto.miod2014-11-1710-9/+30
| | | | | | | | | | | | | | | | | | There used to be a strong reluctance to provide this cipher in LibreSSL in the past, because the licence terms under which Cammelia was released by NTT were free-but-not-in-the-corners, by restricting the right to modify the source code, as well retaining the right to enforce their patents against anyone in the future. However, as stated in http://www.ntt.co.jp/news/news06e/0604/060413a.html , NTT changed its mind and made this code truly free. We only wish there had been more visibility of this, for we could have had enabled Cammelia earlier (-: Licence change noticed by deraadt@. General agreement from the usual LibreSSL suspects. Crank libcrypto.so minor version due to the added symbols.

* Guard RSA / RC4-5 ASM when NO_ASM is not definedbcook2014-08-111-1/+3
| | | | | | | | | Most assembly blocks remain inactive if OPENSSL_NO_ASM is not defined, only enabling inline assembly, but the RSA / RC4-5 blocks (used only in amd64 systems) turn on implicitly. Guard these two as well. This simplifies enabling just inline ASM in portable, no effective change in OpenBSD.
