6d715130a2 linuxkm: cleanups and smallstack refactors related to WOLFSSL_LINUXKM_SIMD_X86_IRQ_ALLOWED, associated linuxkm-SIMD-IRQ PR, and associated peer review: 
smallstack refactors for wolfcrypt/src/rsa.c:wc_CheckProbablePrime_ex() and wolfcrypt/src/pwdbased.c:wc_PKCS12_PBKDF_ex();

add WARN_UNUSED_RESULT macro to types.h;

text format cleanup;

fix internal.c:LowResTimer() implementation.

refactor tls13.c:TimeNowInMilliseconds() for kernel 4.9 and 3.16 compat.

use ktime_get_coarse_real_ts64() only for kernel 5.x+.  in kernel 4.x, use its older form, current_kernel_time64(), and in 3.x, use getnstimeofday().

linuxkm/module_hooks.c: fix wolfssl_init() pie code to be compatible with kernel 4.4-;

fix allocate_wolfcrypt_irq_fpu_states() return codes to all be wolfcrypt codes, and in calling code, pass up that code (suggested by dgarske peer review).

83e0e19e03 linuxkm feature additions: 
add build-time support for module signing using native Linux facility;

add support for alternative licenses using WOLFSSL_LICENSE macro;

improve load-time kernel log messages;

add support for sp-math-all asm/AVX2 acceleration;

add error-checking and return in SAVE_VECTOR_REGISTERS();

implement support for x86 accelerated crypto from interrupt handlers, gated on WOLFSSL_LINUXKM_SIMD_X86_IRQ_ALLOWED:

  * wolfcrypt_irq_fpu_states
  * am_in_hard_interrupt_handler()
  * allocate_wolfcrypt_irq_fpu_states()
  * free_wolfcrypt_irq_fpu_states()
  * save_vector_registers_x86()
  * restore_vector_registers_x86()

add WOLFSSL_LINUXKM_SIMD, WOLFSSL_LINUXKM_SIMD_X86, and WOLFSSL_LINUXKM_SIMD_ARM macros for more readable gating.

3858bda7e9 add "module", "modules_install", and "clean_module" rules to BUILD_LINUXKM section of Makefile.am, and add working install rule to linuxkm/Makefile, so that "make module" and "make modules_install" now work when --enable-linuxkm; fix "make dist" logic in Makefile.am and scripts/include.am to be unaffected by --enable-linuxkm; don't build wolfcrypt/benchmark or testwolfcrypt when --enable-linuxkm and --enable-crypttests. 2020-11-04 14:13:39 -06:00
