this issue is mainly exposed when using larger (4096) client key in TLS mutual auth,
since it uses multiplications > 2048 when mbedtls_mpi_mul_mpi is used in recursion,
which works only if both operands point to different location than result since
mpi_mult_mpi_overlong() called mbedtls_mpi_grow() to reallocate buffers used in previous
pointer arithmetics and thus corrupting it. Fixed by growing the mpi buffer before
calling mpi_mult_mpi_overlong()
Basically, in the portability layer, it is checked if the socket is
NON-block, and if not, then even the EAGAIN and EWOULDBLOCK errors are
diverted to a RECV error. This causes a problem for sockets with
receive timeouts set. When such a timeout is set, the condition for
NON_BLOCK isn't met and hence a hard error is returned.
Searching for EAGAIN and EWOULDBLOCK in lwip returns only 3 results
(accept, recvfrom, close) and all of them look to be genuine cases for
EWOULDBLOCK. So removing this check to make receive timeout with TLS
work.
This commit resolves a blocking in esp_aes_block function.
Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.
Fix some related issue with shared using of AES SHA RSA accelerators.

Avoids growing the result of hardware bignum operations
(particularly for multiplication)
Fixes bugs where some Elliptic Curve operations fail or corrupt memory,
as they assume length of the number is never greater than the number of
non-zero limbs.
Includes some general refactoring to standardize terminology.
Closes https://github.com/espressif/esp-idf/issues/1556
Fixes TW12984
Adds test cases for both these issues.
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.
The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.
ALT header files for sha1, sha256, sha512 are only supposed to declare
mbedtls_sha1_context data structure. Function prototypes should come
from original header files.
The following mbedTLS APIs have been deprecated and replaced with the
new ones which return error codes:
mbedtls_shaX_starts -> mbedtls_shaX_starts_ret
mbedtls_shaX_update -> mbedtls_shaX_update_ret
mbedtls_shaX_finish -> mbedtls_shaX_finish_ret
mbedtls_shaX_process -> mbedtls_shaX_internal_process
Update hardware implementations of SHA functions, and other IDF
components which used above functions, to use new versions.
* Disables 3DES, Camellia, Blowfish, RC4, RIPEMD160, SSLv3, TLS-PSK modes, DTLS by default
* Saves about 40KB from the default TLS client code size
* Defaults no longer get "Bad" howsmyssl.com rating (no more vulnerable 3DES)
(ping https://github.com/espressif/arduino-esp32/issues/575 )
* Allows up to another 20-30KB code size to be trimmed without security
implications if using DER formatted certificates, RSA ciphersuites only,
etc.
* Can save up to another 8KB by setting the TLS Role to Server or Client only.
1. When dual core cpu run access DPORT register, must do protection.
2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro.
Since mbedtls_net_errno is reset by fcntl, it is reset after calling
net_would_block, so the call to mbedtls_net_errno in mbedtls_net_recv
and mbedtls_net_send will always get back 0. This change propagates
the value returned by mbedtls_net_errno up through net_would_block,
to allow the correct error value to be used and avoid a redundant
call to mbedtls_net_errno.
Merges PR #511https://github.com/espressif/esp-idf/pull/511
Add dynamic interrupt allocation mechanism
This adds:
- Dynamic allocation of interrupts. Pass it the features of the interrupt you want, it'll set you up with an int.
- Shared interrupts. Enables multiple peripheral drivers to use the same interrupt.
- Marking what interrupts are fully executable from IRAM; if an int isn't marked like that it will get disabled once flash cache gets disabled.
Also:
- Modifies driver to be in line with these changes

SHA acceleration integrated to mbedTLS incl. TLS sessions
Uses hardware SHA acceleration where available, fails over to software where not available.

rmt.c should include stdlib.h for malloc, esp_bignum,c &
https_request_main.c for abort().
FreeRTOSConfig.h is only including stdlib if
CONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION is set. However, it is
included for abort() so needs to be included whenever
CONFIG_FREERTOS_ASSERT_FAIL_ABORT is set.
This change includes unconditionally in FreeRTOSConfig.h. This is to
avoid this kind of bug where compiler errors are dependent on config. I
suggest we don't change this to be more selective until we have 'make
randomconfig' style tests in CI.
SHA hardware allows each of SHA1, SHA256, SHA384&SHA512 to calculate digests
concurrently.
Currently incompatible with AES acceleration due to a hardware reset problem.

Removes memory barriers for better performance, thanks Ivan for pointing
this out.
Manually unrolling the loop further seemed like diminishing returns.
