[Buildroot] [PATCH next 1/3] tpm2-tss: bump to version 2.1.0

Carlos Santos casantos at datacom.com.br
Fri Nov 16 02:52:15 UTC 2018


- Drop C++ requirement (tmp2-tss is pure C now).
- Add explicit dependency on openssl (gnutls can be used too but this
  option will be added by a subsequent patch).
- Drop the patch on tcti_socket.cpp, which is not applicable.
- Add a patch already submitted upstream to support using libressl[1].
- Update LICENSE hash. The terms are is still BSD-2-Clause but the file
  now contains a SPDX license identifier.

+Subject: [PATCH] ESYS: Fix build with LibreSSL
+
+RAND_bytes() is declared in rand.h. Also, LibreSSL does not provide OAEP
+macros EVP_PKEY_CTX_set0_rsa_oaep_label and EVP_PKEY_CTX_set_rsa_oaep_md
+so use them conditionally.
