ChangeLog.d/chacha20_invalid_iv_len_fix.txt - third_party/github/ARMmbed/mbedtls - Git at Google

 Default behavior changes
    * mbedtls_cipher_set_iv will now fail with ChaCha20 and ChaCha20+Poly1305
      for IV lengths other than 12. The library was silently overwriting this
      length with 12, but did not inform the caller about it. Fixes #4301.
