* development: (182 commits) Change the library version to 2.11.0 Fix version in ChangeLog for fix for #552 Add ChangeLog entry for clang version fix. Issue #1072 Compilation warning fixes on 32b platfrom with IAR Revert "Turn on MBEDTLS_SSL_ASYNC_PRIVATE by default" Fix for missing len var when XTS config'd and CTR not ssl_server2: handle mbedtls_x509_dn_gets failure Fix harmless use of uninitialized memory in ssl_parse_encrypted_pms SSL async tests: add a few test cases for error in decrypt Fix memory leak in ssl_server2 with SNI + async callback SNI + SSL async callback: make all keys async ssl_async_resume: free the operation context on error ssl_server2: get op_name from context in ssl_async_resume as well Clarify "as directed here" in SSL async callback documentation SSL async callbacks documentation: clarify resource cleanup Async callback: use mbedtls_pk_check_pair to compare keys Rename mbedtls_ssl_async_{get,set}_data for clarity Fix copypasta in the async callback documentation SSL async callback: cert is not always from mbedtls_ssl_conf_own_cert ssl_async_set_key: detect if ctx->slots overflows ...
