linuxkm/Makefile: update the GENERATE_RELOC_TAB recipe to generate both wc_linuxkm_pie_text_reloc_tab[] and wc_linuxkm_pie_rodata_reloc_tab.
linuxkm/linuxkm-fips-hash-wrapper.sh: add handling for wc_linuxkm_pie_rodata_reloc_tab.
linuxkm/linuxkm-fips-hash.c: add handling for rodata_reloc_tab.*.
linuxkm/linuxkm_memory.c:
* refactor find_reloc_tab_offset() to be segment-agnostic and tolerate empty reloc tabs.
* refactor wc_reloc_normalize_segment():
* to be segment-agnostic,
* identify the src segment dynamically,
* return BAD_FUNC_ARG where previously returning literal -1,
* use seg_in_out_len arg to accommodate size skew between input and output (not currently used), and
* rename working vars for better mnemonicitude.
* update wc_fips_generate_hash() to
* handle seg_map->rodata_reloc_tab,
* use new calling convention for wc_reloc_normalize_segment(), and
* add wc_reloc_normalize_segment() loop for .rodata_wolfcrypt.
linuxkm/linuxkm_memory.h and linuxkm/linuxkm_wc_port.h: rename WOLFSSL_TEXT_SEGMENT_CANONICALIZER* to WOLFSSL_SEGMENT_CANONICALIZER*, with backward-compat provisions.
linuxkm/module_hooks.c:
* add wc_linuxkm_normalize_relocations_noresize() backward-compat wrapper.
* wolfssl_init(): add .rodata_wolfcrypt relocation handling alongside existing .text_wolfcrypt handling, and update for new wc_reloc_normalize_segment() calling convention.
* add seg_map.rodata_reloc_tab initialization.
* update wc_linuxkm_normalize_relocations() to be segment-agnostic and use new wc_reloc_normalize_segment() calling convention.
linuxkm/linuxkm_memory.c:
* fix straddle check in wc_reloc_normalize_text();
* fix seg_map bounds checks in wc_fips_generate_hash();
linuxkm/linuxkm_memory.h: fix initializer for wc_reloc_table_segments.bss_end;
wolfssl/wolfcrypt/settings.h: add WC_BITS_TO_BYTES() and WC_BITS_FULL_BYTES() and deploy opportunistically to wolfssl/internal.h, wolfssl/wolfcrypt/{asn.h,dh.h,rsa.h,types.h}, wolfcrypt/src/sakke.c, and wolfcrypt/test/test.c.
configure.ac: add --enable-kernel-verbose-debug and --enable-kernel-stack-debug;
linuxkm/Makefile:
* add QFLAG and VFLAG setup, and pass their values appropriately;
* add missing `@set -e` and `-Wall -Wextra` to the linuxkm-fips-hash recipe;
* use +$(MAKE), not @$(MAKE), for proper dry run recursion.
linuxkm/README.md: update to reflect new goodies, and generally revise+extend remarks.
linuxkm/linuxkm-fips-hash-wrapper.sh: add copyright header; pass through extra caller arguments to ./linuxkm-fips-hash.
linuxkm/linuxkm-fips-hash.c:
* add copyright header;
* fix code around user_coreKey;
* add explicit wolfCrypt_Cleanup() and cleanup of mod_fd and mod_map at end;
* remove unused reloc_tab_len
* fix a couple -Wsign-compares;
* add missing fprintf arguments
* properly set ret = -1 in a couple failure paths.
linuxkm/linuxkm_wc_port.h: set WOLFSSL_LINUXKM_VERBOSE_DEBUG when WOLFSSL_KERNEL_VERBOSE_DEBUG, and recognize WOLFSSL_KERNEL_STACK_DEBUG as a synonym for WC_LINUXKM_STACK_DEBUG.
linuxkm/linuxkm_memory.c and linuxkm/linuxkm_memory.h: add brief explanatory comments.
Add:
* linuxkm/linuxkm-fips-hash.c
* linuxkm/linuxkm-fips-hash-wrapper.sh
* linuxkm/linuxkm_memory.h
Move from linuxkm/module_hooks.c to linuxkm/linuxkm_memory.c:
* reloc_layouts[]
* find_reloc_tab_offset()
* the body of wc_linuxkm_normalize_relocations() as wc_reloc_normalize_text()
* most of updateFipsHash() as wc_fips_generate_hash()
Move from linuxkm/linuxkm_wc_port.h to linuxkm/linuxkm_memory.h:
* struct wc_linuxkm_pie_reloc_tab_ent
* enum wc_reloc_dest_segment
* enum wc_reloc_type
linuxkm/Makefile:
* Update GENERATE_RELOC_TAB recipe to populate new fields in struct wc_reloc_table_ent.
* Add targets:
* libwolfssl-user-build/src/.libs/libwolfssl.so
* linuxkm-fips-hash
* module-with-matching-fips-hash
* module-with-matching-fips-hash-no-sign
* Add support for alternate target module name, via LIBWOLFSSL_NAME make variable.
linuxkm/linuxkm_wc_port.h and linuxkm/module_hooks.c:
* Fixes to make linuxkm-pie work with CONFIG_KASAN.
* Implement WC_LINUXKM_STACK_DEBUG:
* wc_linuxkm_stack_bottom()
* wc_linuxkm_stack_top()
* wc_linuxkm_stack_current()
* wc_linuxkm_stack_left()
* wc_linuxkm_stack_hwm_prepare()
* wc_linuxkm_stack_hwm_measure_rel()
* wc_linuxkm_stack_hwm_measure_total()
wolfssl/wolfcrypt/settings.h:
* When WOLFSSL_KERNEL_MODE, make sure WOLFSSL_GENERAL_ALIGNMENT is at least SIZEOF_LONG.
* When WOLFCRYPT_FIPS_CORE_DYNAMIC_HASH_VALUE, make sure WOLFSSL_BASE16 is defined.
configure.ac and wolfcrypt/benchmark/benchmark.c: Disable scrypt when KERNEL_MODE_DEFAULTS, due to excessive memory requirements.
