* Add TLSv1.3 stateful support
Fix internal and external session cache
* session cache fixes
* Refactor
- implement wolfSSL_CTX_flush_sessions
- use wolfSSL_CTX_flush_sessions to make test_wolfSSL_CTX_add_session_ext deterministic
- add dtls to test_wolfSSL_CTX_add_session_ext
- DoClientTicket_ex does not modify ssl object
- only call session remove callback on:
- timeout
- session is being overwritten/removed from the cache
* Session fixes
- restore bogus ID on session duplicate
- don't evict on overwrite
- use memmove instead on memcpy as `ssl->session == session` is possible
- ignore ClientSession parameter in AddSessionToCache on NO_SESSION_CACHE_REF
- use sessionID when altSessionID not present
* Session fixes
- DoClientTicketFinalize: always copy in the ID as teh altSessionID
- don't overwrite ex_data when overwriting cacheSession and cacheSession owns it
* Callback wants to retain a copy
* wolfSSL_GetSessionClient: ssl->ctx->get_sess_cb does not apply here
* test_wolfSSL_CTX_add_session_ext
gate expected results on WOLFSSL_DTLS_NO_HVR_ON_RESUME
* TlsSessionIdIsValid: copy return can't be ignored
* Silence unused parameter
* test_wolfSSL_CTX_add_session_ext: handle async case
* Gate wolfSSL_SSL_CTX_remove_session on NO_SESSION_CACHE
* ssl.c: style fixes
* Add twcase_get_sessionCb_cleanup to free external cache
* Remove hard tab
* Correct build error in wolfSSL_CTX_flush_sessions
* Jenkins fixes:
- altSessionID only available with WOLFSSL_TICKET_HAVE_ID
- slim out psk_sess_free_cb_ctx
* Stateful dtls case has 2 accesses. Stateless just one.
* Add version numbering to hostap logs
* Import internal.h for test_wolfSSL_SESSION_get_ex_new_index
* wolfSSL_SetSession: don't check SslSessionCacheOff for session setting
* wolfSSL_SetSession: fully set expired session for OpenSSL compatibility
* wolfSSL_SetSession: check if setting same object
* AddSession: always populate the session object to allow re-use
* Add logging to wolfSSL_NewSession and wolfSSL_FreeSession
* Always setup session object
* Check if session has been setup before setting it
* Print errors in async test
* Make SetupSession available outside NO_SESSION_CACHE
* Review comments
* Fix ticBuf leak and TlsSessionIdIsValid logic
* Fix unmatched curly brackets
* TlsSessionIdIsValid: always need to check copy var
* TlsResumptionIsValid: set resume to FALSE default
* wolfSSL_SetSession: remove now variable since only used in one place
* Move internalCacheLookupOff into HAVE_EXT_CACHE block

Ed25519CheckPubKey/Ed448CheckPubKey: get the public key from certificate
in a new function, wc_CertGetPubKey, that uses less memory.
Set the ENCRYPT_BASE_BITS to minimal values when Curve448/Curve25519 are
the largest public key algorithms.
* refactor error-checking cascade in wc_PemCertToDer_ex() as in wc_PemPubKeyToDer_ex(),
* refactor staticBuffer gating/dynamics in wc_PemPubKeyToDer_ex() as in wc_PemCertToDer_ex(),
* and use IO_FAILED_E, not BUFFER_E, for I/O errors on the file handles, in both routines;
fix smallstack null pointer dereferences in src/pk.c:wolfSSL_RSA_GenAdd() and src/ssl.c:set_curves_list().
Minimize use of stack.
Make very large stack allocations dynamic memory allocations unless
WOLFSSL_SP_NO_MALLOC.
ProcessBufferTryDecode() split up into a function for each type.
ProcessBufferTryDecodeRsa() decodes the data and gets key size rather
than having or allocating an RsaKey.
Added wc_RsaPrivateKeyValidate() that only validates the encoding is an
RSA key and returns the key size in bytes.
For SP int, only create sp_ints of required size in RSA and ECC
implementation. For WOLFSSL_SMALL_STACK, memory is allocated to have
just enough bytes and size is set to maximum supported. Otherwise,
relies on dynamic stack variables.
For ECC, MAX_ECC_BITS_USE used when dynamic stack variables not
supported. Significantly reduces memory usage when RSA/DH is also built.
Add macros to sp_int.h, tfm.h and integer.h to support declaring,
allocating, initializing and freeing mp_ints.
For integer.h, mp_int is always static as size is no more than 32 bytes.
For tfm.h, WOLFSSL_SMALL_STACK has a full mp_int allocated, otherwise
the full mp_int is put on the stack.
For sp_int.h with new macros, dynamically allocate sp_int to minimal
size when WOLFSSL_SMALL_STACK, or when dynamic stack variables, declare
them to be of minimal size or otherwise declare with a fixed max.
Added mp_bitsused(), for all implementations, to get the number of bits
available based on used. Included for RSA to get the size of the
modulus.
SP int now always uses dynamic stack variables if possible rather than
for builds with WOLFSSL_SP_SMALL.
Moved code out into separate functions so that stack allocations don't
happen when not going down code path.
linuxkm/module_exports.c.template: include wolfssl/wolfcrypt/wolfmath.h, to bring in wc_GetMathInfo() prototype;
src/ssl.c: move "Global pointer to constant BN on" to src/ssl_bn.c; and in wolfSSL_Cleanup(), call the new wolfSSL_BN_free_one() rather than using ad hoc cleanup logic;
src/ssl_bn.c: add bn_one and wolfSSL_BN_free_one();
src/ssl_asn1.c: fix bugprone-macro-parentheses in bufLenOrNull(); refactor wolfSSL_ASN1_TIME_diff() to avoid floating point math; use intermediate tm_year variable in wolfssl_asn1_time_to_tm() to avoid target-specific type conflicts on tm->tm_year; use "FALL_THROUGH", not "/* fall-through */", in wolfSSL_ASN1_TYPE_set (clang-diagnostic-implicit-fallthrough);
wolfcrypt/src/ecc.c: fix identicalInnerCondition in ecc_mul2add();
wolfcrypt/src/integer.c: refactor OPT_CAST()s in mp_grow() to unconditional casts as elsewhere, to mollify a confused cppcheck-all-intmath;
tests/api.c: reformat some overlong lines.
Fix checking of negative with unsigned variables.
Check digestSz for 0 in wc_SSH_KDF() so that no possibility of dividing
by zero.
Change XMEMCPY to XMEMSET in renesas_sce_util.c.
Fix test.c to free prvTmp and pubTmp on read error.
Remove unused variables.
XFREE checks for NULL so don't check before call.
Move variable declarations to reduce scope.
Implementations of ASN.1 APIs reworked.
Added tests.
Added wolfssl_bn_set_neg for ASN.1 code.
Added wolfssl_sk_new_type() and wolfssl_sk_pop_type() to generically
handle creating and popping a stack of elements of a type.
No longer freeing pathlen field of ASN1 OBJECT in
wolfSSL_X509_EXTENSION_free(). This is happening in
wolfSSL_ASN1_OBJECT_free().
Stop wolfSSL_i2d_X509_NAME_canon from double freeing ASN.1 STRING's data
field.
Fixed up GetFormattedTime() to be better code.
Added ASN_CLASS_MASK to mask off the class part of an ASN.1 tag.
NO_ASN_TIME means no implementation to get the current time. Disable
features that won'r work without time.
ForceZero the client and server secret regardless of whether TLS 1.3 as
it may change but have been copied in.
ForceZero the input buffer in wolfSSL_Clear() when encryption was on.
Changed wc_PRF_TLS to only check the parts of data used.
Changed where scatch is added for checking in wc_AesCtrEncrypt.
Change wc_MakeRsaKey to memset p, q, tmp1, tmp2 and tmp3 to all zeros so
that MemZero check works. Memset not needed otherwise.
Changes for new compiler - thinks uninitialized.
