Purpose:
This will allow for easily automating periodic updates to
"cacrt_all.pem" file.
Note:
For now newly created "cacrt_local.pem" contains single "DST Root CA X3"
which we are keeping to manage compatibility with endpoints like
"howsmyssl.com". Please note this Root CA is expired and is not part of
Mozilla’s NSS root certificate store.
When GEN_FILES is enabled, Perl interpreter should be available. There
is a check in mbedTLS that disables GEN_FILES on Windows (where Perl
is not available by default) but it is broken for recent CMake
versions.
Also set Python interpreter to the one IDF uses, just to avoid calling
into some other Python version which CMake might manage to find.
In commit de22f3a4e5, combination of
hardware and software MPI (bignum) related approach was used to
work around chip (e.g. ESP32-C3) limitation of max 3072 bits support.
This was done using linker "--wrap" flag but since the relevant API is
being used in same translation (compilation unit), hardware mode was not
getting used in some cases (e.g., RSA key generation).
This commit modified internal mbedTLS API and makes software+hardware
combination deterministic.
Building mbedtls with CMake would warn that:
"A private source from a directory other than that of target "mbedcrypto
has a relative path"
This happened due to some of the CMake variables listing sources could be empty.
Changed to only use target_sources in the code-path where we set the sources,
so we only call target_sources will non-empty variables.
Closes https://github.com/espressif/esp-idf/issues/6767
Removed the old dynamically allocated GDMA channel approach.
It proved too unreliable as we couldn't not ensure consumers of the mbedtls
would properly free the channels after use.
Replaced by a single shared GDMA channel for AES and SHA, which won't be
released unless user specifically calls API for releasing it.
MbedTLS: Add software fallback for Modular Exponentiation for larger bignum operations
Closes WIFI-3257 and IDFGH-132
See merge request espressif/esp-idf!11928
Add configuration option to fallback to software implementation
for exponential mod incase of hardware is not supporting it
for larger MPI value.
Usecase:
ESP32C3 only supports till RSA3072 in hardware. This config option
will help to support 4k certificates for WPA enterprise connection.
* Replaced crypotoauthlib with esp-cryptoauthlib
* Added menuconfig option for esp-tls about using HSM
* Added error codes for HSM in esp-tls,
* Added support to select different type of ATECC608A chips
* Added README, updated docs
* tcp_transport: Added option to enable secure_element for ssl
Closes https://github.com/espressif/esp-idf/issues/4432
When compiling esp_crt_bundle.c, it would end up with a different struct layout due
to configuration options from "mbedtls/esp_config.h" not being considered.
This lead to ca_chain potentially not being set correctly.
Adds the ESP certificate bundle feature that enables users to bundle a
root certificate bundle together with their application.
Default bundle includes all Mozilla root certificates
Closes IDF-296

!4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link
components built under ESP-IDF build system. However, LINK_LIBRARIES does
not produce behavior same as linking PRIVATE. This MR uses the new
signature for target_link_libraries directly instead. This also moves
setting dependencies during component registration rather than after all
components have been processed.
The consequence is that internally, components have to use the new
signature form as well. This does not affect linking the components to
external targets, such as with idf_as_lib example. This only affects
linking additional libraries to ESP-IDF libraries outside component processing (after
idf_build_process), which is not even possible for CMake<v3.13 as
target_link_libraries is not valid for targets not created in current
directory. See https://cmake.org/cmake/help/v3.13/policy/CMP0079.html#policy:CMP0079
Since !4452 the common component requirements automatically get
privately linked to libraries built under ESP-IDF build system (this
includes targets from third-party libraries). This removes a variable
that was used for that purpose before !4452.
Since the internal target names were changed, the compile definition for
warning on using deprecated functions is not being passed. Since using
the internal name is unreliable, prefer passing this compile definition
from the test itself.
