742492cb5e linuxkm/Makefile: fix module sign-file error handling. 2021-11-01 11:49:48 -06:00
Daniel Pouzzner
fc73c6dbea linuxkm: fix Makefile to properly pivot module signature on CONFIG_MODULE_SIG==y; remove not-yet-kernel-compatible asm files from the ASFLAGS_FPU_DISABLE_SIMD_ENABLE list, matching the OBJECT_FILES_NON_STANDARD list, for clarity. 2021-10-26 20:24:28 -05:00

3745b1c9db linuxkm: fix clean rules/definitions to not pick up top level Makefile, and to clean up empty object directories. 2021-10-26 20:24:27 -05:00

947a0d6a2f autotools/Makefiles: enable reproducible build by default for FIPS, and add -DHAVE_REPRODUCIBLE_BUILD to AM_CFLAGS; 
refactor the HAVE_WC_INTROSPECTION mechanism to pass build params via $output_objdir/.build_params rather than abusing autotools config.h to pass them;

add support for EXTRA_CFLAGS on the make command line;

in FIPS builds, exclude pkcallbacks from --enable-all;

linuxkm: move test.o out of PIE container (uses function pointers as operands).

34e88b0605 linuxkm: properly pass {AM_,}CPPFLAGS to Kbuild, and include kdf.h in module_exports.c.template. 2021-10-26 20:24:26 -05:00

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.

--enable-linuxkm-pie (FIPS Linux kernel module) (#4276) 
* Adds `--enable-linuxkm-pie` and associated infrastructure, to support FIPS mode in the Linux kernel module.
* Adds `tests/api.c` missing (void) arglist to `test_SSL_CIPHER_get_xxx()`.

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
