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.
peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"
Using these ciphers can constitute a security risk if the server
uses a weak prime for the key exchange.
Footprint impact:
Roughly 3K saved in text+rodata in default https_request example
Driver was using the channel ID from tx when reseting rx.
But since rx and tx is not necessarily from the same pair this could lead
to the driver reseting the wrong DMA channel.
Updates the following with changes from verification branches:
* esp_rom linker files
* rtc_cntl and system reg and struct headers
Also updates:
* GDMA driver with new register layout
* esptool submodule commit
This commit add following crypto changes
1. Update current crypto code with upstream supplicant code
2. Add a proper porting layer to use mbedtls APIs for all the crypto
operations used by supplicant.
Internal crypto will be used when USE_MBEDLTS flag is disabled
in supplicant's menuconfig.
This commit also removes the clutter in crypto files due to partial
porting of some APIs to mbedtls, all the code from those files have
been removed and rewritten in a generic way, this is inspired from
current upstream code.
This also reduces the lib size significantly, supplicant's lib
size reduces around ~567kb after this change(NB: lib size doesn't
indicate reduction in final bin size).
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.
RX process caches the session information in "ssl->in_ctr" not in "ssl->in_buf".
So when freeing the SSL, can't free the "ssl->in_ctr", because the "ssl->in_buf"
is empty.
Make the RX process like TX process, and cache the session information in
"ssl->in_buf", so that the cache buffer can be freed when freeing the SSL.
Closes https://github.com/espressif/esp-idf/issues/6104
DMA process didnt wait for idle before returning.
This meant that there was a potential for the dma
descriptors which were on the stack to be reclaimed
before the DMA operation finished.
