wolfSSL_clear: check return from InitSSL_Suites() call.
TLS13: check ClientHello cipher suite length is even.
Silently remove duplicate cipher suites from user input.
Add tests of duplicate cipher suite removal.
Handle multiple instances of the same cipher suite being in the server's
list.
Fix client order negotiation of cipher suite when doing pre-shared keys.
- Use WOLF_SK_COMPARE_CB() to generate the correct types instead of using void* for the callback parameters.
- Remove WOLFSSL_STACK.comp entirely since it is not used anywhere. Ignore input parameters that used to set this member.
This function would only accept the string "SHA" for SHA-1-based HMAC, but it
should also accept "SHA1." This is similar to how wolfSSL_EVP_get_digestbyname
allows both "SHA" and "SHA1." We didn't have a test for this in api.c. I added
one, and it failed before my fix here.
Don't reserve the full message length of memory. Instead we only allocate memory for the fragments that we have already received. We also dynamically combine memory fragments when we receive overlap.
- wire the wc_ChaCha_* implementation into the EVP API
as `wolfSSL_EVP_chacha20`
- follow IV conversions of OpenSSL
- add test case
- have QUIC support use this for header protection when
CHACHA20_POLY1305 has been negotiated in the handshake.
Ed25519 and Ed448 make public key APIs now check whether the private key
was set.
The private key and public key flags setting and clearing also updated.
Testing of unset private key and calling make public key added for
Ed25519 and Ed448.
Detect when certificate's RSA public key size is too big and fail on
loading of certificate.
Fix unit test to only attempt to use 3072 bit RSA-PSS keys when
RSA_MAX_SIZE supports it.
* Add test case for OpenSSLs capability to init a evp context partially in several calls.
* EVP handling of CHACHA20_POLY1305 improvment
- save key at ctx for Init()s without IV
- reuse stored key for Init()s with new IV, reusing ctx
- free and zero key on ctx clenaup
* Adding type cast to XMALLOC to force compiler compatibility.
* EVP: using same DYNAMIC_TYPE in alloc and free of chacha20_poly1305 key.

in api.c test_wolfSSL_dtls12_fragments_spammer(), inhibit clang-analyzer-deadcode.DeadStores;
in asn.c ParseCRL_Extensions() old (!WOLFSSL_ASN_TEMPLATE) version, fix bounds check to prevent overshift;
in misc.c ctMaskCopy(), use `*(x + i)`, not x[i], to tiptoe around cppcheck-2.9 objectIndex bug.
This function was just freeing the stack object itself of GENERAL_NAMES with
wolfSSL_sk_free, but this doesn't free the data in the items of the stack. The
fix is to replace wolfSSL_sk_free with wolfSSL_sk_GENERAL_NAME_free.
1. In api.c, change the name of the devId global to testDevId.
2. In api.c, for the SNI test, some of the pointers were multiply
typecast eventually to `void **`. An older compiler didn't like
that. Just use void pointer.
OpenSSL compat expects ASN_SELF_SIGNED_E when a self signed cert can't be verified. This is useful when translating the error with GetX509Error into a X509_V_ERR_* error.
Support wolfSSL_CTX_set1_curves_list being available when X25519 and/or
X448 only defined.
Don't recognize X25519 or X448 if corresponding define is not set.
Enable test in api.c.
Add support for parsing and verifying certificates with RSA-PSS
signatures. Including check PSS parameters in key with those in
signature algorithm.
Add support for parsing private RSA PSS key.
Add support for parsing public RSA PSS key.
- Modify all existing tests to return an int. This moves us in the direction of
being able to return error/success from a test rather than just calling abort
when something fails. Also, all tests now have the same signature, so they can
easily be members of an array of test cases.
- Wrap each test in a TEST_CASE struct, which just stores a pointer to the test
function and the name of the test, for now. In the future, other metadata can
be added (e.g. should this test be run/skipped) to TEST_CASE, if desired.
- Modify all tests to return 0 on success. Right now, this doesn't do us much
good because the failure mechanism isn't returning some value != 0, it's
abort.
- Add TestSetup and TestCleanup functions that run before and after each test,
respectively. The former does nothing right now, and the latter clears the
error queue, if the error queue is compiled in.
wolfSSL_ERR_get_error and wolfSSL_ERR_peek_error_line_data should return the
earliest error in the queue (i.e. the error at the front), but prior to this
commit, they returned the latest/most recent one instead.
In DoAlert, we were adding an error to the queue for all alerts. However, a
close_notify isn't really an error. This commit makes it so DoAlert only adds
errors to the queue for non-close_notify alerts. In ReceiveData, similarly, we
were adding an error to the queue when the peer sent a close_notify, as
determined by ssl->error == ZERO_RETURN. Now, we don't add an error in this
case.
add wolfCrypt error codes IO_FAILED_E "Input/output failure" and SYSLIB_FAILED_E "System/library call failed";
tests/api.c and tests/unit.c: flush stdout for error message in Fail() macro, add fflush(stdout) after printf()s, print success message at end of unit_test(), and send several error messages to stderr instead of stdout;
wolfcrypt/test/test.c: add fallthrough macro definition of printf() that pairs it with fflush(stdout);
unit.h: in definition of macro AssertPtr(), add PRAGMA_GCC("GCC diagnostic ignored \"-Wpedantic\"");
sp_int.c: refactor several lingering instances of "if (0) { ... }" code pattern to #if 0 ... #endif.
1. Rename _DtlsUpdateWindow() as wolfSSL_Dtls_UpdateWindow() and make
it public so it may be tested.
2. Rename the internal functions DtlsWindowUpdate(), DtlsWindowCheck(),
and DtlsUpdateWindowGTSeq() as _DtlsWindowUpdate() and
_DtlsWindowCheck(), and _DtlsUpdateWindowGTSeq().
3. When updating the DTLS sequence window, and the next sequence
number (lo) wraps to zero, increment the next sequence number (hi)
by 1.
4. Fix an off-by-one error that wrapped around when saving the
packet sequence number in the bit-field window.
5. Adding a test for wolfSSL_DtlsUpdateWindow() function. With many test
cases. It is set up in a table format with running check values.
6. Change location of incrementing the difference when calculating the
location for setting the bit.
7. Updated the check of the sequence difference in the GT scenario.
8. In the DTLS window update functions remove newDiff and just use diff.
9. Handle the cases where the DTLS window crosses the high order word
sequence number change.
10. Add a debug option to print out the state of the DTLS sequence number
window.
In defense against attack, assume the imported public key is not trusted
and check it matches the private key if set.
Added APIs that allow application to explicitly trust public key.
Original APIs default to not trusting public key.
Add a define WOLFSSL_CHECK_MEM_ZERO to turn on code that checks that
memory that must be zeroized before going out of use is zero.
Everytime sensitive data is put into a allocated buffer or stack buffer;
the address, its length and a name is stored to be checked later.
Where the stack buffer is about to go out of use, a call is added to
check that the required parts are zero.
wc_MemZero_Add() adds an address with length and name to a table of
addressed to be checked later.
wc_MemZero_Check() checks that the memory associated with the address is
zeroized where required.
mp_memzero_add() adds mp_int's data pointer with length and name to
table.
mp_memzero_check() checks that the data pointer is zeroized where
required.
Freeing memory will check the address. The length was prepended on
allocation.
Realloction was changed for WOLFSSL_CHECK_MEM_ZERO to perform an
allocate, check, copy, free.
With PR 5170, I added logic that requires a EVP_CTRL_GCM_SET_IV_FIXED command be
issued before a EVP_CTRL_GCM_IV_GEN command. This matches OpenSSL's behavior.
However, OpenSSL also clears the flag enabling EVP_CTRL_GCM_IV_GEN after
EVP_CTRL_GCM_SET_IV_FIXED if EVP_CipherInit is called with a NULL key.
Otherwise, the flag retains its value. We didn't mirror this logic, and that
caused problems in OpenSSH unit testing. This commit aligns our logic with
OpenSSL's and adds a regression test to test_evp_cipher_aes_gcm for this case.
* PKCS7 should use allocated buffer for RSA.
* PKCS7 small stack typo for `keyAlgArray` size in `wc_PKCS7_AddRecipient_KTRI`.
* Fix for use of `free`, which should be `XFREE` in api.c.
* Cleanup old RSA benchmarking MDK5/WINCE code no longer needed with `WC_DECLARE_ARRAY_DYNAMIC_DEC` and `WC_DECLARE_ARRAY_DYNAMIC_EXE`.
Discovered the AES-GCM flow using this command didn't work in our OpenSSH port.
This commit makes the behavior match OpenSSL and adds testing using known
OpenSSL-generated test vectors to prevent regressions. This was one of those
problems where two ends of a connection would work fine if they were both using
wolfSSL but not if one was using OpenSSL (i.e. OpenSSH interop with AES-GCM
was broken).
Prior to this commit, if you wanted access to the Finished messages from a
handshake, you needed to turn on the compatibility layer, via one of
OPENSSL_ALL, WOLFSSL_HAPROXY, or WOLFSSL_WPAS. With this commit, defining any
of these causes WOLFSSL_HAVE_TLS_UNIQUE to be defined (a reference to the
tls-unique channel binding which these messages are used for) in settings.h.
This allows a user to define WOLFSSL_HAVE_TLS_UNIQUE to access the Finished
messages without bringing in the whole compat layer.
