Fix for case:
- can't find a signer for a certificate with the AKID
- find it by name
Has to error as the signer's SKID is always set for signer and would
have matched the AKID.
Simplify the path length code - don't look up CA twice.
Don't require the tsip_encRsaKeyIdx field in DecodedCert when
!WOLFSSL_RENESAS_TSIP - use local variable.
RFC 5280, Section 4.1.2.6:
If the subject is a CA (e.g., the basic constraints extension, as
discussed in Section 4.2.1.9, is present and the value of cA is TRUE),
then the subject field MUST be populated with a non-empty distinguished
name matching the contents of the issuer field (Section 4.1.2.4) in all
certificates issued by the subject CA.
The subject name must match - even when the AKID matches.
Cap the incoming DTLS handshake messages size the same way we do for
TLS. If handshake messages claim to be larger than the largest allowed
certificate message, we error out.
1. Add parsing of CRL extensions, specifically the Auth Key ID extension.
2. To verify CRL, search for CA signer by AuthKeyId first, then by name. If NO_SKID is set, just use name.
3. Update the ctaocrypt settings.h for the NO_SKID option with CRL so FIPS builds work.
1. Remove some redundant AM_CONDITIONAL macros checking for OCSP and CRL.
2. Moved the AM_CONDITIONAL macro setting BUILD_PKCS12 to the other AM_CONDITIONALS.
1. One of the error string was >80 bytes long. Shortened it.
2. The function that copies an error string to an output array needs to
ensure the string is still null terminated.
3. Added a check to the wolfCrypt test to see that error strings aren't
>= 80 bytes long.
1. Fix some preprocessor flag checking for function EncodePolicyOID. It
also needs to be available for OpenSSL Compatibility.
2. Fix for a name string for a test that can get left in or out
incorrectly.
When building with `WOLFSSL_ALT_CERT_CHAINS` a peer's presented CA could be incorrectly added to the certificate manager, marking it as trusted.
Began in PR #1934
ZD 9626
Handle prime (modulus) of 0 and 1.
Handle exponent of 0.
Fix for base of 0 in fp_exptmod and hadnle base of 0 in mp_exptmod.
fp_exptmod - Don't modify X's sign during operation when passed in as negative.
Value to invert: a
Modulus: b
integer.c - normal math
- a is one, or a mod b is one
tfm.c - fast math
- b is -ve (error), or b is zero
- a is zero or a mod b is zero
1. Undo an earlier change with respect to parsing a long length with
length zero. If BerToDer is disabled, this will be treated as a zero
length. With BerToDer enabled, the conversion will do the right thing.
1. Remove the function Word32ToString and replace with calls to
XSNPRINTF().
2. Simplify DecodePolicyOID(), which converts an ASN.1 OID to a text
string in the form a.b.ccccc.d... Return an error if it gets too long.
If the top bit is set then the encoding routine will drop a byte of the
serial number.
Better to ensure number is positive, top bit clear, and use as much of
the serial number data as possible.
1. Prime test should return NO for 1. (ex function, normal math and fast
math)
2. Call mp_init() on the k value for the primality test case in the
wolfCrypt test.
1. Added a test case for checking "1" as a prime number to the wolfCrypt
test.
2. Allow the wolfCrypt prime test for SP builds.
3. Modify the prime test to use mp_mul rather than mp_mul_d, as the SP
math library doesn't export sp_mul_d.
1. Updated the window scrolling. There was a couple off-by-one errors in
the DTLS window handling. They canceled each other out, but there was a
rare case where they would shift too much.
When encrypting with AES-GCM, AES-CCM, or PolyChacha, do not increment
the DTLS sequence number. The sequence number should only be incremented
in BuildMessage. This was done because the sequence number used to be
incremented after calculating the HMAC or after the encrypt for AEAD
ciphers. The HMAC has been separated from the sequence increment.
1. Check array index bounds before using them in arrays.
2. When processing an HTTP buffer, check that the new buffer size is
valid before allocating a new one.
1. When getting the DH public key, initialize the P, G, and Pub pointers
to NULL, then set that we own the DH parameters flag. This allows
FreeSSL to correctly clean up the DH key.
1. For OCTEON builds, leave out the "-DCVMX_BUILD_FOR_LINUX_HOST" option
from CFLAGS by default so it makes standalone host builds.
2. Add a check of the variable OCTEON_HOST for linux to add back in the
"-DCVMX_BUILD_FOR_LINUX_HOST" to CFLAGS.
In verify, two points are added and they may either be the same point
(different z) or result in infinity.
If they are the same point then a double needs to be performed instead.
Detection of infinity added.
Calculation of wc_ecc_sig_size fixed to handle wehn there are more bits
in the order than in the modulus.
* Fixed `set1_curves_list` API's to use `const char*` for names.
* Fixed `ossl_typ.h` to include `ssl.h` compatibility.
* Added `SSL_CTX_up_ref`.
* Added `wolfSSL_set1_curves_list`
* Added `TLS_method` and `DTLS_method`
* Added `SSL_CIPHER_standard_name`.
* Added `X509_STORE_CTX_get0_cert`
* Added `SSL_CTX_set_cert_verify_callback`.
* Enabled "either" side support when `--enable-opensslall` is used.
* Changed `SSL_CIPHER_get_rfc_name` to use `wolfSSL_CIPHER_get_name` instead of stub.
* Reduced codesize when building with `OPENSSL_EXTRA_X509_SMALL`.
* Additional argument checks in `wolfSSL_ASN1_BIT_STRING_set_bit`, `wolfSSL_ASN1_STRING_to_UTF8`, `wolfSSL_RSA_meth_new`, `wolfSSL_RSA_meth_set`.
* Fix for compiler warnings in asn.c using strncmp to duplicate string. "specified bound depends on the length of the source argument"
Add ABI tags to the functions wolfSSL_Cleanup() to match wolfSSL_Init(),
wolfSSL_X509_free to match wolfSSL_load_certificate_file() which
allocates memory.
1. Add a blank #define WOLFSSL_ABI to tag functions as part of the ABI
to remind developers there are rules about those functions specifically.
2. Added allocators and deallocators for WC_RNG objects and ecc_key
objects so they don't have to be used on the stack.
3. Add tests for the new allocators.
Only set the name string in one place, keeping a length of the name type
to copy. Also only move cert data index once.
Reset certificate extension policy number/count in case of malicious
cert with multiple policy extensions.
1. When retaining the handshake resources for a session using resumption, do not delete the peer's certificate. If keeping peer certificates is enabled, the certificate needs to exist so it may be examined.
2. Free the saved peer certificate when receiving a peer certificate during a renegotiation.
Salt length larger than the hash size allowed in RSA-PSS.
Passing -2 to PSS pad function uses maximum salt length.
Passing -2 to PSS un-pad function makes it discover salt length.
For the sync QAT, the QAT headers are included into the library after it
has been built and is being used. The actual headers should only be used
when building wolfSSL and should be hidden from the user.
1. Most of the functions in the sync QAT and OCTEON headers don't need
to be exported. Move all of that into the source files. Only export the
init and deinit functions.
2. Remove inline from the OCTEON support functions.
3. Remove the AES-ECB files for sync OCTEON as unused.
4. Configure defaults to OCTEON2 build, can be overridden with variable.
1. Switched the IntelQa sync API back to local.
2. Added two functions to setup and cleanup the IntelQA device.
3. Changed the Octeon functions to match the IntelQa functions.
4. Updated sniffer, wolfcryptest, and benchmark.
Added back some changes from a dropped commit.
1. The Octeon README should be a stub.
2. Changed the license notice in the octeon sync files back to GPLv2.
3. Added a flag to Aes that needed a build guard around it.
4. Replaced the disable for sniffer session stats.
1. The QAT callback's worker functions need to copy the IV into the AES IV register. QAT doesn't update it automatically.
2. Update the GMAC test to set its device to INVALID_DEVID.
3. Always allocate NUMA buffers before running crypto operation and store the results.
4. The QAT does not like non-multiple of 4 iv lenths, and aad lengths. Or 0. Remove a few test cases for those.
5. QAT wasn't getting a pointer to store the auth tag for GCM. Then store it.
1. Add configure option for sync IntelQA that uses the crypto callback API.
2. Make a synchonous copy of the quickassist files.
3. Tie in the crypto device to the sniffer.
4. When making a sniffer build, define static DH enabled.
5. The readme files in the Cavium were being added to the distro optionally, changed to always add the readme files.
6. Added an include of the cavium_octeon header in the wc_ports.c.
7. Updated the Cavium OCTEON callback for AES-GCM.
8. Add the global tag to the list of crypto callback function pointers.
9. Add an accessor to the OCTEON crypto callback module to return the device ID of the OCTEON device.
10. Add a new version of ssl_SetWatchKeyCallback which takes an additional parameter of a device ID. This ID is used to set up the wolfSSL_CTXs in the sniffer session trackers.
11. Update the benchmark to use sync OCTEON and QAT.
1. Add --enable-libwebsockets option
2. Add OPENSSL_NO_EC (used in libwebsockets)
3. Add SSL_MODE_RELEASE_BUFFERS and debug message for when wolfSSL_CTX_set_mode doesn't recognize a mode.
There was a problem with the combination of DTLS, OpenSSL Compatibility,
and FIPSv2 where the DTLS server would fail out because a HMAC key was
too short. FIPS requires a HMAC key be a minimum size. The DTLS server
uses HMAC to generate the first cookie key when initialized. When using
OpenSSL, the feature for creating a DTLS endpoint with its side being
set late is tested. The DTLS cookie wasn't getting set at init because
the server was "neither" at the time. Added a call to set cookie when
initializing a neither endpoint into a server.
1. Better length checking on the IPv6 extension headers.
2. Removed the default size update analogous to the IPv4 header check
function. It cannot ever be 0, so the update was unnecessary.
Fix failing jenkins test cases
Add detection for file size with static memory
Account for cert without pathLen constraint set including test cases
Resolve OCSP case and test where cert->pathLen expected to be NULL
end of packet pointer. The end of packet pointer is based on sslFrame
and sslBytes. sslBytes is calculated from the total length in the IP
header, rather than the caplen. The caplen may include things like
Ethernet's FCS, which throws packet processing off.
1. Fixed an issue when a TLS record is split across two chain buffers.
The second buffer was being treated as a new record.
2. Fixed an issue with STARTTLS_ALLOWED where the input buffer isn't
getting cleared and the skipped data just builds up blocking TLS
records.
Added a callback and support to allow one to handle storing the data
directly without reallocating the data buffer. Also added an example
that uses this callback if the callback is enabled in the build.
1. Added a new build option for a TITAN session cache that can hold just over 2 million session entires.
2. Reordered the cache options from largest to smallest.
1. Add configure option for sync IntelQA that uses the crypto callback API.
2. Refactor the IntelQA configure checks so they are usable by both the sync and async options.
3. Make a synchonous copy of the quickassist files.
4. Replace the printfs in the code with a logging macro.
5. Added padding to the AES_KEY structure for WOLF_CRYPTO_CB.
6. Tie in the crypto device to the sniffer.
7. When setting up the symmetric operation, add a build case for the sniffer to use malloc instead of realloc. Sniffer usually uses the middle of another buffer for the input data rather than the beginning of the buffer as it has the TCP/IP data to handle as well.
8. Add the raw key to the DES3 structure.
9. Copy the functions from qa_mem over to qa_sync.
Various fixes for uninitialized variable use.
sniffer.c: close file when seek fails
tls.c: fix QSH_GET_SIZE macro
wolfio.c: uIPGenerateCookie: use the parameter, _ctx, instead of self
referencing.
wolfssl_adds.c: check for equivalent to XBADFILE to indicate error.
SP: change right shift of signed value to unsigned
sp_int.h: define 128-bit types
types.h: change a XMALLOC define to not use (,,) - cppcheck doesn't like
it and is unnecessary.
* Added detection for buffer alignment to avoid memcpy.
* Added MD5 and SHA-1 support for XTRANSFORM_LEN to process blocks.
* Cleanups for consistency between algorithms and code commenting.
* Enhancement for NXP MMCAU to process more than one block at a time.
* Improved MMCAU performance: SHA-1 by 35%, SHA-256 by 20% and MD5 by 78%.

merged from private repo
removed unneccessary #include
make line as 80 characters
added simple tls server
Disable TLS-linked API use when being SERVER SIDE, still use certificate verify API
Added utility tools, generate signature arrays etc
added vars to store tsip hmac keys
fix build failure when disabling dc_printf
This allows SP to support:
- DH parameter checking
- DH parameter generation
- RSA key generation
Improved performance of sp_mod operation.
Reworked some functions to have one exit point (return statement).
Fixed sp_sub_d().
Changed tests to perform 2048-bit RSA key generation only when using SP
math.
Fixed Intel x86_64 C file to not have DH specific functions available
unless WOLFSSL_HAVE_SP_DH is defined.
Fixed tfm to return an error when t is not the correct size in
fp_isprime_ex().
Feature: Added support for testing date override at build-time using `TEST_BEFORE_DATE`.
```
./examples/server/server -H overrideDateErr -A ./certs/ca-cert.pem -k ./certs/server-key.pem -c ./certs/intermediate/server-chain.pem &
./examples/client/client -D -A ./certs/ca-cert.pem -k ./certs/client-key.pem -c ./certs/intermediate/client-chain.pem
```
ssl.c: Certificate store fields freed without being NULLed and then
freed again.
integer.c: Compiler complained that a->dp may be NULL in mp_set_bit when
setting bit.
pkcs12.c: ret is zero after GetLength and this is an error but data is
freed only when ret != 0.
pkcs7.c: derArr was not zeroized for full allocated size.
To go with the fix for the functions wolfSSL_(i2d|d2i)_SSL_SESSION,
modify the example client to use a serialized session record for
resumption instead of the direct reference into the session cache. This
change only happens when OPENSSL_EXTRA and HAVE_EXT_CACHE are defined.
Right shift of a negative value is undefined.
Add an 'int' return version of constant time greater than equal.
Change equal and not equal to be constant time in more situations.
Changes
- Don't ignore decryption errors when doing TLS 1.3 and after Client
Finished.
- Put out an alert when TLS 1.3 decryption fails.
- Properly ignore RSA pss_pss algorithms when checking for matching
cipher suite.
- Check X25519 public value before import in TLS v1.2-
- REcognise TLS 1.3 integrity-only cipher suites as not negotiable with
TLS 1.2-.
- Send decode_error alert when bad message data in CertificateVerify.
- Negotiate protocol version in TLS 1.3 using extension and keep
decision when using TLS 1.2 parsing.
- Must have a signature algorithms extension in TLS 1.3 if not doing
PSK.
- More TLS v1.3 alerts.
- MAX_PSK_ID_LEN needs to be modified at compile time for tlsfuzzer to
work.
- change the good ecc public key to be a real public key when compiled
to check imported public keys
- Fix early data in TLS 1.3
- Make max early data size able to be changed at compile time - default
4K but fuzzer sends 16K
- Fix HRR, PSK and message hashes: Don't initialize hashes in parsing
ClientHello as need to keep hash state from previous ClientHello and
HelloRetryRequest
When using the configure options '--enable-certgen --enable-certext CPPFLAGS=-DWOLFSSL_VALIDATE_ECC_IMPORT', the ecc_decode_test() will fail the "good" test case. It is using the point (1, 1) in the test, and that fails the key validation. Changed the good key to one of the keys we have in the certs directory. The additional validation checks that the point is on the curve, and is validated in FIPS mode.
In configure.ac,
1. Change some whitespace in the FIPS enable section.
2. Reorganize the FIPS section a little bit.
3. When enabling wolfRand, also force cryptonly.
4. Treat wolfRand like FIPSv2 at build time.
In the source include.am,
5. Add checks against BUILD_FIPS_RAND as appropriate.
6. Add the SHA-256 assembly to the wolfRand source list.
1. Rearrange some of the macros in the FIPS section to separate out the
different flavors of FIPS with their own flags to set them apart.
2. Add automake flags for FIPSv1 and wolfRand.
Example log output for test case where `client_hello` sent a cipher suite list and server choose a cipher suite not in the list:
```
wolfSSL Entering DoServerHello
ServerHello did not use cipher suite from ClientHello
wolfSSL Leaving DoHandShakeMsgType(), return -501
wolfSSL Leaving DoHandShakeMsg(), return -501
```
RFC 5246: 7.4.1.3: Server Hello: `cipher_suite: The single cipher suite selected by the server from the list in ClientHello.cipher_suites.`
Systems with sizof(int) == 2 default to expressions with that size.
So we have to do some explicit casts or use unigned long constants in
some cases.
In ssl.h the prototype of a function was not matching the definition.
This resulted in a type incompatibility on a 16-bit system.
Fixes to ARM code
- put in it instruction before conditional for old compilers.
- fix small code size version of compare
- handle not being able to shift by the full size - want result to be
zero
Casts as required by compiler to reduce bit size explicitly.
When building with GCC-8 and enable-intelasm set, GCC reported a memcpy
from and two the same pointer being possible. Added a check for the same
pointer and skipped the copy if the same.
One of the tests for PKCS8 depended on keys encrypted with a password
that has only 8 letters. HMAC in FIPS mode requires a minimum of 12
bytes. Disabled that test case when FIPS is enabled. All components do
get tested just not all together in that case.
1. Check the sizes picked up out of the message against the expected
size of the record when looking at the certificate messages.
2. Renamed the cert and certSz in the watch callback with it being a
certChain.
Create the OCSP Response for Stapling and TLS 1.3 when parsing.
When parsing OCSP stapling extension with TLS 1.3, use a new extension
object if it was created.
Set the extension size to 0 before writing extensions when sending a TLS
1.3 Certificate message.
Modifed the sniffer watch callback so it provides a SHA-256 hash of the
peer certificate, as before, and the entire certificate chain sent by
the server in the Certificate handshake message. The chain is taken
directly from the message payload, unprocessed. It'll be a list of pairs
of 24-bit certificate length and a DER encoded certificate, all in
network byte order.
Only check picking the hash and signature algorithm functions return
when a certificate is available to send to peer.
Include the ECC signature and hash algorithms in available list even
when using ECDSA certificates signed with RSA.
List is of capabilities not what is in certificate.
Certificate request sent to peer doesn't have to be an ECDSA certificate
signed with RSA.
Same treatment for RSA.
1. Split the function ssl_SetWatchKey() into ssl_SetWatchKey_file()
which loads the key from a named file and ssl_SetWatchKey_buffer()
which loads the key from a provided buffer. file() uses buffer().
Added the build option for the Watch mode for the sniffer. Instead of
setting a set of IP addresses and keys, you set a callback function.
When any TLS connection is started, the hook is called and a hash of the
peer certificate is given to the callback function. It has a chance to
load a private key into the sniffer session. Enable this option with the
build flag "WOLFSSL_SNIFFER_WATCH".
Do version negotiation first. Look for, parse and negotiate with
SupportedVersions extension upfront. Only need to handle TLS 1.3
ClientHello after this.
Any version greater than TLS 1.2 in Legacy Version field is translated
to TLS 1.2.
Fix preMasterSz to when not using PreSharedKey.
Not finsing KeyShare in ClientHello sends a missing_extension alert.
Decoding signature algorithms in new TLS 1.3 range now returns error
when not recognized.
Don't allow RSA PKCS #1.5 signatures to be verified.
Fix accept when downgraded from TLS 1.3 to go to wolfSSL_accept.
Fix server state when sending ChangeCipherSpec for MiddleBox
compatability.
Send a new session ticket even when resuming.
When major version is TLS Draft then this is now ignored.
If version negotitation occurs but none matched then send an alert and
return an error.
Store the rsa_pss_pss_* signature algorithms in the bit mask.
KeyShare Entry parsing returns INVALID_PARAMETER when length is 0 and
results in a different alert being sent.
Check negotiated protocol version is not TLS 1.3 when determing whether
to parse point formats.
If not FFDHE parameters in list then use existing.
If FFDHE parameters present but none matching then let the ciphersuite
match process fail when DHE must be used.
Better checking of encrypted alerts - check unencrypted data size
correctly before using data.
Send an alert if the alert isn't the right size.
Send an alert if the maximum alert count has been reached - but don't
send it if seeing close_notify alert.
1. Moved sslKeyFails.
2. Added sslEphemeralMisses, sslEncryptedConns, sslDecodeFails.
3. Removed the Rehandshake stats as the sniffer does not support rehandshaking.
4. Removed two of the per second stats as they seemed redundant.
5. Added a function to atomically read and reset the sniffer statistics.
1. Wrapped the added code for statistics in a preprocessor guard.
2. Added a check for the current cipher suite and if it is on the list
of allowed suites. Guarded by the statistics option.
3. Added more statistics from the list.
1. Added a structure for all the statistics to be kept.
2. Added a global to track the statistics.
3. Added a copy function to get a copy of the statistics.
4. Added a reset function for the statistics.
5. Handle the alert messages in statistics.
1. Remove redundant calls to the generate function when instantiating
and reseeding the DRBG.
2. Added note to the apparently redundant extra call to the generate
function when running the self test. This extra call is there to make
sure the internal state is updating correctly as a part of the KAT.
3. Removed duplicate enable argument clause for rng from configure.ac.
Replace some removed constants for AES-NI. They were removed when the
inline assembly that used that was exported to its own file.
For Windows, we're using the C intrinsic AES-NI functions, and those
still needed those constants.
Consolidate all the AM_CONDITIONAL statements in one place in the
configure process. This replaces the set of repeat checks of enable
flags to conditionally check the AM_CONDITIONAL.
performs the decrypt in the old manner before a particular bug was
fixed. The old method didn't add padding when the data to encrypt was
multiple of the block_size in length. The decrypt happened to ignore the
error returned by checkPad.
Fix up ARM32 Curve25519 assembly code to use right directives.
Slight improvement to ARM64 SHA-512 assembly code.
Don't return error code from Transform functions - can't fail.
The `WOLFSSL_SHA256_ALT_CH_MAJ` alternate Ch/Maj performance is the same.
The `SHA256_MANY_REGISTERS` is about 13% slower on 64-bit. On some platforms is slightly faster.
Added freedom-e-sdk based makefile
Updated ecc test code to not allocate more memory than requried
Run wolfcrypt and benchmark tests on the SiFive HiFive1 targets
1. When collecting the key size to log it, use the constant WOLFSSL_BIT_SIZE for the bytes->bits multiply.
2. When converting the size of the ECC key, break the steps out more explicitly. Also update the comment to be more accurate.
New compile time option WOLFSSL_PSK_ONE_ID. Indicates one identity
available. No need for client to call callback when generating binder -
already cached.
1. Moved the CopySessionInfo function to a better location for the additions.
2. Added accessors for a callback and application context data.
3. Added a callback that is called from ProcessClientKeyExchange when everything is known about the start of the current session.
4. Added the private key size and the server name indication to the SSLInfo record.
1. Refactor `ProcessClientKeyExchange()` so it can be expanded to handle ECC keys for ECDH support.
2. Add support to the sniffer for ECDH based cipher suites.
* Fixes for building wolfSSL from GitHub sources download, where .git does exist. The autogen.sh still needs to "touch" files for the build to work.
* Fix for FIPS case where `wc_RsaSetRNG` is not available.
* Added new `./configure --enable-usersettings` option to not populate the Makefile with build options and instead define `WOLFSSL_USER_SETTINGS` and expect a user provided `user_settings.h` file.
* Fix for `HAVE___UINT128_T` to match config.h generated value to eliminate warning.
When calling wolfSSL_EVP_DigestInit() with an unsupported string, the
macType should be set to NONE, rather than ignored. In a particular
build combination, functions using that EVP could false the type because
of memory garbage. Just set it in the else case.
* Added new `WOLFSSL_TELIT_M2MB` build option to enable support for RNG, Time, Mutex, FileSystem and Directory.
* Added `XTIME_MS` macro to simplify the tls13.c layer time requirement.
* Cleanup of the wolfCrypt benchmark and test printf remapping.
* Added wolfCrypt optional memory test enabled with `COMPLEX_MEM_TEST`.
* Added wolfCrypt test / benchmark feature for allowing "sleep" between long operations using `TEST_SLEEP()`.
* Fix for extern with `sp_ModExp_2048` when building with `--cpp` option.
1. Rearrange the deprecation cryptodev option so it doesn't overwrite the cryptocb option, and so it doesn't break its case in the build-test.
2. Fix the content length in the sample HTTP used by the example server.
3. Disable OCSP stapling in the example server if RSA is disabled.
4. Fix a variable in asn.c that was declared in the middle of its scope.
5. Retag the xmalloc, xrealloc, xfree functions used in the memory test as WOLFSSL_API like all the other allocators, instead of extern.
1. Fix for the enable-afalg option from Jacob Barthelmeh.
2. Client fix for enable-sp+enable-sp-math option from David Garske.
3. Added a couple of typecasts to some mallocs.
4. Modified the option guard for the mask member of Options for the webserver build.
5. Added some more padding to the opaque structures used for SHA_CTX and AES_KEY.
6. Added WOLFSSL_API to the stack logging functions.
Bump the version number in configure.ac and updated the version.h. The
library version wasn't updated between v3.15.7-stable and the snapshot
v3.15.8, so I bumped it for this release.
When enable-all and disable-rsa is configured, some of the tests needed
for all don't work because they only use RSA keys or certificates.
Disabled those test cases in that build combination.
One of the external sites contacted for the OCSP stapling test
increased the size of one of their intermediate certificates. The test
failed silently as the certificate was ignored. Increased the
FP_MAX_BITS so that the test can pass with the enable-all option. That
option was setting the FP_MAX_BITS for 3072-bit certificates, and the
site in question is using a 4096-bit certificate.
1. The combination enable-all and disable-rsa breaks some of the
testing. Added the NO_RSA guards as appropriate.
2. Disabled the OCSP stapling and CRL tests when RSA is disabled as they
use test certificates with RSA keys.
1. Removed redundant includes of files.
2. Moved all the files in the viewer into the appropriate directories.
3. Updated the copy rules so the missing include files are copied to the destination for all the three possible targets.
2. Check the trusted CA id pointer for NULL before copying.
3. Updated the api test for the NO_SHA change.
4. Remove the TCA options member as redundant.
Added an API for enabling the Trusted CA Key Indication extension from
RFC6066 section 6. If the server doesn't have a match for the client,
the client will abandon the session.
Add some typecasts to the RSA constant time data copy so it doesn't
misbehave with some embedded compilers that do the integer promotion in
a different order than expected.
In at least one environment the check for particular AR options was
failing due to a bash script bug. Deleted an extra pair of parenthesis
triggering an arithmetic statement when redundant grouping was desired.
2. Put SecureResume in terms of a regular resume, using Get/SetSession
and then calling Rehandshake.
3. Add the startScr after checking secure_renegotiation enabled during a
resume.
Fix wc_ecc_fp_free() to be called when using HAVE_STACK_SIZE.
Increase size of replyin client.c so all HTTP reply is displayed.
Fix api.c to support only Ed25519 (not RSA and ECC)
Fix suites.c to detect when CA for client won't work (Ed25519 only)
For Static Memory add debugging and small profile.
Also allow realloc to be called with NULL.
Add more Ed25519 certs and keys.
Fix names of Ed25519 filenames for client and server.
Do NOT turn on ECC_SHAMIR by default with lowresource.
Enable WOLFSSL_STATIC_MEMORY_SMALL if low resource and no RSA.
subject ID on renegotiation. Both endpoints are already
cryptographically linked on an encrypted channel.
2. The error code list has gaps where deprecated codes were deleted,
remove the redundant gaps where there aren't missing codes.
1. Split the wolfSSL_Rehandshake() function into wolfSSL_Rehadshake()
which performs a full handshake on secure renegotiation and
wolfSSL_SecureResume() which performs a session resumption on a
secure renegotiation.
2. Add option to example client to perform a secure resumption instead
of a full secure handshake.
Add support for the fixed FFDHE curves to TLS 1.2. Same curves in TLS
1.3 already. On by default - no checking of prime required.
Add option to require client to see FFDHE parameters from server as per
'may' requirements in RFC 7919.
Change TLS 1.3 ClientHello and ServerHello parsing to find the
SupportedVersions extension first and process it. Then it can handle
other extensions knowing which protocol we are using.
__attribute__ ((mode(TI))) does not really work on clang-cl,
linking would fail with "unresolved external symbol __udivti3",
as reported in https://bugs.llvm.org/show_bug.cgi?id=25305
Fix to use default case with 28bit digits on clang-Windows.
If the old length checking method is desired `NO_STRICT_ECDSA_LEN` can be used. This would allow extra signature byes at the end (unused and not altering verification result). This is kept for possible backwards compatibility.
Per RFC6979: `How a signature is to be encoded is not covered by the DSA and ECDSA standards themselves; a common way is to use a DER-encoded ASN.1 structure (a SEQUENCE of two INTEGERs, for r and s, in that order).`
ANSI X9.62: ASN.1 Encoding of ECDSA:
```
ECDSA-Sig-Value ::= SEQUENCE {
r INTEGER,
s INTEGER
}
```
Fixes#2088
OCSP uses an identified hash of the issuer's public key to identify the
certificate's signer. (Typically this is SHA-1, but can be any SHA
hash.) The AKID/SKID for the certificates usually are the SHA-1 hash of
the public key, but may be anything. We cannot depend on the AKID for
OCSP purposes. For OCSP lookups, wolfSSL calculates the hash of the
public key based on the copy saved for use with the handshake signing.
For RSA, that was fine. For ECDSA, we use the whole public key including
the curve ID, but for OCSP the curve ID isn't hashed. Stored the hash of
the public key at the point where we are looking at the key when reading
in the certificate, and saving the hash in the signer record.
Getting the seed from a device has been added.
If the HASH_DRBG is available, PKCS#11 will be used for generating the
seed.
Otherwise, all generated random data will come from PKCS#11 device.
hardware acceleration with RSA
add AES-GCM hardware acceleration
refactor setting RSA IV flag
check and set AF_ALG flags
fix for default AF_ALG use
set buffer alignment with Xilinx RSA
macro guard after rebase
use ALIGN64
clean up test cases
- Added support for Deos with no file system
- Implemented a custom malloc since reusing and freeing memory is disallowed in avionics and mission critical applications.
- Added TLS client and server example with a TCP setup mailbox transport
- Timer starts at an offset of CURRENT_UNIX_TIMESTAMP specified by the user
- Uses rand_r() as a pseudo random number generator and uses the current time in seconds as a seed
- Uses strnicmp for XSTRNCASECMP instead of strncasecmp
- a readme doc included
* Support for building `WOLFSSL_SAFERTOS` without heap.
* Allows `XSTRNCASECMP` macro to be customized.
* USER_TIME supports checks for existing `strct tm` and `time_t`.
Modify the DtlsMsgPoolSend() function to keep track of the last message
retransmit. If a write would block, it allows the retransmit pick up
where it left off.
Do not allow the DTLS message flight be retransmit without being
finished. This can happen if a non-blocking transmit times out the
response and the application tries to retransmit.
1. Add a second select for tx.
2. Revised tcp_select to work for either rx or tx.
3. Updated client and server to use new tcp_select_tx() for checking the
tx socket if the nonblocking connect/accept would block on transmit.
1. Add error code for trying to retransmit a flight when transmitting
the flight hasn't finished.
2. Add function to retransmit the stored flight without updating the
timeout count.
1. In DTLS, when transmitting the Change Cipher Spec message increment the
sequence number.
2. In DTLS, when client receives the CCS message, sanity check that the
server hello has been received in the case of resume.
1. In the client, check the return code on wolfSSL_CTX_SetMinDhKey_Sz() as it is checked in the server. (Resolves issue #2037.)
2. In HashOutput(), check that the hsHashes exists for the session before hashing. (Resolves issue #2038.)
Fixed a potential bug with respect to processing fragmented handshake
messages. If a handshake message is fragmented across multiple TLS
records and the last fragment's record has the next handshake message in
it, we would throw a buffer error instead of processing the next
message. Changed this so it will finish the handshake message and return
out to process the next message. Also changed the handling of the
handshake message to follow the calling pattern.
* Added support for running as only Client (`-c`) or Server (`-s`).
* Added support for using sockets (in addition to in memory mode `-m`).
* Fixed support for 16KB test packet (memory version needed TLS header space). Changed to default to 16KB.
* Fixed so transfer is done on each connection and there is not transfer limit (instead "shutdown" message is used).
* Made pthread support optional and based on HAVE_PTHREAD.
* Tested non-blocking support with sockets or shared memory.

```
* Added ECC and RSA intermediate CA's and server/client chain certificates for testing.
* Enhanced suites test to support expected fail arg `-H exitWithRet` in any test .conf file.
* Added new `test-altchains.conf` for testing with `WOLFSSL_ALT_CERT_CHAINS` defined.
* Added new `test-chains` for testing chains.
* Added new `test-dhprime.conf` for DH prime check tests.
* Added new `test-trustedpeer.conf` for testing `WOLFSSL_TRUST_PEER_CERT`.
* Refactor to add `-2` to disable DH prime check by default (except for new test-dhprime.conf).
* Added ability to run a specific test.conf file using syntax like `./tests/unit.test tests/test-altchains.conf`.
* Fix with `WOLFSSL_ALT_CERT_CHAINS` to resolve issue with using a trusted intermediate to validate a partial chain. With the alt cert chain enabled a CA may fail with only `ASN_NO_SIGNER_E` and the connection is allowed if the peer's certificate validates to a trusted CA. Eliminates overly complex 1 deep error alternate chain detection logic. Resolves ZD 4525.
* Refactor and cleanup of ProcessPeerPerts to combine duplicate code and improve code commenting.
* Fix for CA path len check in `ParseCertRelative` to always check for self-signed case (was previously only in NO_SKID case).
* Improvement to include self-signed flag in the DecodedCert struct.
Put the clientState into CLIENT_HELLO_RETRY (new state) when waiting for
second ClientHello.
Chrome sends change_cipher_spec message, for reasons of compatability,
which meets the requirements of the Old ClientHello detection when state
of client is NULL.
1. Fix testing issue with a client using the SCSV cipher suite to indicate desire for renegotiation.
2. Add indication to both the server and client examples that the renegotiation was successful.
1. Add an extra guard check around a call to SendHelloRequest() in the case where server renegotiation is disabled.
2. Replaced an accidental deletion of an include of the misc.h header for no inline builds.
1. Add the server side renegotiation flag to the secure renegotiation option.
2. Changed the AddEmptyNegotiationInfo so it doesn't create an extension, just adds a reply if SCR is enabled.
3. Fix the server's reaction to the client sending the SCR extension.
1. Fix an incorrect function entry log string.
2. Restart the server's accept state assuming the client hello was
received when the client initiates renegotiation.
1. Add enables to the example server for turning on secure renegotiation.
2. Add encryption assists to the handhshake message handler functions.
3. Add a hello request message function. Includes handshake timing pre/postambles.
Fixed wrong error checks, changed return value to the size of the derived key, added support for the case where data == NULL and removed the assignment of constant value to info->ivSz (the correct value is assigned to it inside 'wc_EncryptedInfoGet')

##### This release of wolfSSL includes a fix for 6 security vulnerabilities.
A fix for having an additional sanity check when parsing certificate domain names was added. This fix checks that the domain name location index is not past the maximum value before setting it. The reported issue affects users that are parsing certificates and have --enable-opensslextra (macro OPENSSL_EXTRA), or build options that turn this on such as --enable-all, when building wolfSSL. The CVE associated with the fix is CVE-2019-18840.
Fix to set a limit on the maximum size of DTLS handshake messages. By default the RFC allows for handshake message sizes of up to 2^24-1 bytes long but in typical field use cases the handshake messages are not this large. Setting a maximum size limit on the handshake message helps avoid a potential DoS attack due to memory being malloc’d. The new default max size is set to handle a certificate chain length of approximately 9, 2048 bit RSA certificates. This only effects builds that have DTLS turned on and have applications that are using DTLS.
Fix for a potential hang when ECC caching is enabled (off by default) and --enable-fastmath is used. ECC caching is off by default and is turned on in builds that are using --enable-all or --enable-fpecc. This issue does not affect builds that are using the macro WOLFSSL_VALIDATE_ECC_IMPORT which turns on validating all ECC keys that are imported. To fix this potential hang case a sanity check on the input values to the internal invmod function was added.
To fix a potential fault injection attack on a wrapper function for wolfCrypt RSA signature generations an additional sanity check verifying the signature after it’s creation was added. This check is already done automatically in current versions of wolfSSL with TLS connections (internal function call of VerifyRsaSign during TLS state machine). The report only affects users making calls to the wolfCrypt function wc_SignatureGenerateHash and does not affect current TLS use cases. Thanks to Daniel Moghimi (@danielmgmi) from Worcester Polytechnic Institute for the report.
Blinding was added for DSA signing operations. The DSA signing uses the BEEA algorithm during modular inversion of the nonce which can potentially leak the nonce through side channels such as cache and power fluctuations. The fix of adding in blinding makes the DSA signing operation more resistant to side channel attacks. Users who have turned on DSA (disabled by default) and are performing signing operations should update. Note that DSA is not used in any TLS connections. Thanks to Daniel Moghimi (@danielmgmi) from Worcester Polytechnic Institute for the report.
Fix to add additional side channel cache attack resistance to the internal ECC function wc_ecc_mulmod_ex. This function by default is used with ECDSA signing operations. Users should update if performing ECDSA singing operations (server side ECC TLS connections, mutual authentication on client side) or calling wolfCrypt ECC sign functions and have the potential for outside users to perform sophisticated monitoring of the cache.Thanks to Daniel Moghimi (@danielmgmi) from Worcester Polytechnic Institute for the report.

Fix for sanity check on reading TLS 1.3 pre-shared key extension. This fixes a potential for an invalid read when TLS 1.3 and pre-shared keys is enabled. Users without TLS 1.3 enabled are unaffected. Users with TLS 1.3 enabled and HAVE_SESSION_TICKET defined or NO_PSK not defined should update wolfSSL versions. Thanks to Robert Hoerr for the report.
Fix for potential program hang when ocspstapling2 is enabled. This is a moderate level fix that affects users who have ocspstapling2 enabled(off by default) and are on the server side. In parsing a CSR2 (Certificate Status Request v2 ) on the server side, there was the potential for a malformed extension to cause a program hang. Thanks to Robert Hoerr for the report.
Two moderate level fixes involving an ASN.1 over read by one byte. CVE-2019-15651 is for a fix that is due to a potential one byte over read when decoding certificate extensions. CVE-2019-16748 is for a fix on a potential one byte overread with checking certificate signatures. This affects builds that do certificate parsing and do not have the macro NO_SKID defined.Thanks to Yan Jia and the researcher team from Institute of Software, Chinese Academy of Sciences for the report.
High level fix for DSA operations involving an attack on recovering DSA private keys. This fix affects users that have DSA enabled and are performing DSA operations (off by default). All users that have DSA enabled and are using DSA keys are advised to regenerate DSA keys and update wolfSSL version. ECDSA is NOT affected by this and TLS code is NOT affected by this issue. Thanks to Ján Jančár for the report.

Medium level fix for potential cache attack with a variant of Bleichenbacher’s attack. Earlier versions of wolfSSL leaked PKCS #1 v1.5 padding information during private key decryption that could lead to a potential padding oracle attack. It is recommended that users update to the latest version of wolfSSL if they have RSA cipher suites enabled and have the potential for malicious software to be ran on the same system that is performing RSA operations. Users that have only ECC cipher suites enabled and are not performing RSA PKCS #1 v1.5 Decryption operations are not vulnerable. Also users with TLS 1.3 only connections are not vulnerable to this attack. Thanks to Eyal Ronen (Weizmann Institute), Robert Gillham (University of Adelaide), Daniel Genkin (University of Michigan), Adi Shamir (Weizmann Institute), David Wong (NCC Group), and Yuval Yarom (University of Adelaide and Data61) for the report.

# wolfSSL Release 3.15.5 (11/07/2018)
Release 3.15.5 of wolfSSL embedded TLS has bug fixes and new features including:
ARM® TrustZone® CryptoCell 310 is a security subsystem which provides root of trust (RoT) and cryptographic services for a device.
You can enable the wolfSSL support for ARM CryptoCell using the `#define WOLFSSL_CRYPTOCELL`, The CryptoCell APIs are distributed as part of the Nordic nRF5 SDKs [here](https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fgroup__cryptocell__api.html) .
## Prerequisites
1. Follow the Nordic website [here](https://www.nordicsemi.com/Software-and-Tools/Software/nRF5-SDK) to download the Nordic nRF5-SDK and software tools.
2. Install the SEGGER Embedded Studio IDE.
3. Run a simple blinky application on your Nordic nRF52840 (PCA10056) development board to confirm that your board functions as expected and the communication between your computer and the board works.
## Usage
You can start with a wolfcrypt SEGGER embedded studio (ses) example project to integrate the wolfSSL source code.
wolfSSL supports a compile-time user configurable options in the `IDE/CRYPTOCELL/user_settings.h` file.
The `IDE/CRYPTOCELL/main.c` example application provides a function to run the selected examples at compile time through the following two #defines in user_settings.h. You can define these macro options to disable the test run.
```
- #undef NO_CRYPT_TEST
- #undef NO_CRYPT_BENCHMARK
```
## Supported features
- SHA-256

- RTC for benchmark timing source
## Setup
### Setting up Nordic SDK with wolfSSL
1. Download the wolfSSL source code or a zip file from GitHub and place it under your SDK `InstallFolder/external/` directory. You can also copy or simlink to the source.
Or, assuming you have already cloned the wolfSSL source code under ~/wolfssl.
$cd ~/nRF5_SDK_15.2.0_9412b96/external
$ln -s ~/wolfssl wolfssl
```
2. Copy the example project from [here](https://github.com/tmael/nRF5_SDK/tree/master/examples/crypto/nrf_cc310/wolfcrypt) into your `nRF5_SDK_15.2.0_9412b96/examples/crypto/nrf_cc310/` directory.
4. In the main menu, go to File >Open Solutions to open the example solution. Browse to the location containing the wolfcrypt code `/examples/crypto/nrf_cc310/wolfcrypt/pca10056/blank/ses/wolfcrypt_pca10056.emProject` and choose Open.
## Building and Running
In the main menu, go to Build > Rebuild your project, then load and run your image on your nRF52840 target platform. Review the test results on the console output.
### `wolfcrypt_test()`
wolfcrypt_test() prints a message on the target console similar to the following output:
```

You can enable the wolfSSL support for Deos RTOS available [here](https://www.ddci.com/products_deos_do_178c_arinc_653/) using the `#define WOLFSSL_DEOS`.
Deos is a time & space partitioned, multi-core enabled, DO-178C DAL A certifiable RTOS.
## Usage
You can start with your OpenArbor IDE-based example project for Deos with the network stack (lwip) to integrate wolfSSL source code.
wolfSSL supports a compile-time user configurable options in the `IDE/ECLIPSE/DEOS/user_settings.h` file.
The `tls_wolfssl.c` example application provides a simple function to run the selected examples at compile time through the following four #defines in user_settings.h. You can undefine any of these macro options to run a test.
```
1. #undef NO_CRYPT_TEST
2. #undef NO_CRYPT_BENCHMARK
3. #undef NO_WOLFSSL_CLIENT
4. #undef NO_WOLFSSL_SERVER
```
Do one of the following steps for building and running wolfSSL with the Deos kernel examples, which are included in the DDS release:
If you want to create a project from scratch, skip the Importing the project section and follow the steps in the other sections.
If you want to use an pre-configured example project, go to the Importing the project section, skip the other sections and follow the Building and Running section.
#### Importing the project
In this section you will import a pre-configured example project.
1. Launch the OpenArbor IDE as an administrator
2. In the Workspace Launcher dialog, in the Workspace field, enter your
workspace
3. Right-click in the Project Explorer view and select Import
4. In the Import dialog, select General > Existing Projects into Workspace, then click Next.
5. In the Import Projects dialog, select Select archive file, then browse to `IDE/ECLIPSE/DEOS/` and double-click `deosWolfssl.zip` file
6. In the Import Projects dialog, click Finish
#### Setting up a Deos project with wolfSSL
1. Download the wolfSSL source code or a zip file from GitHub. You can remove all of the files except for these folders and its contents. The top folder for this example is wolfsslPort.
```
wolfsslPort
|-- IDE
| -- ECLIPSE
| -- DEOS
|-- src
|-- wolfcrypt
| -- benchmark
| -- src
| -- test
|-- wolfssl
|-- openssl
|-- wolfcrypt
|-- port
```
2. Remove these two platform specific assembly source files:
- wolfsslPort/wolfcrypt/src/aes_asm.asm
- wolfsslPort/wolfcrypt/src/aes_asm.S
3. Launch the OpenArbor IDE as an administrator
4. Create a DDC-I Deos example project. In the main menu, go to File >DDC-I Deos example project > socket > udp-vs-tcp
5. Import the `wolfSSLPort` source code into your project.

Depending on your configuration, wolfSSL uses upto four mutexes. You also need to configure enough memory for the stack of each threads and the process logical memory pool.
2. Right click on the `udp-vs-tcp` project, select properties and add the following macros in the DDC-I Options > C Compile > Preprocessor
- DEOS_ALLOW_OBSOLETE_DEFINITIONS
- WOLFSSL_USER_SETTINGS
3. Add the following directory paths in the DDC-I Options > C Compile > Directories and in the DDC-I Options > C++ Compile > Directories
- $(PROJECT_DIR)/wolfsslPort
- $(PROJECT_DIR)/wolfsslPort/wolfssl
- $(PROJECT_DIR)/wolfsslPort/IDE/ECLIPSE/DEOS
- $(PROJECT_DIR.printx)/code
4. Change the optimization level in the DDC-I Options > C Compile > Code Generation > Optimization level:g
- g
5. Add the following library dependencies in the DDC-I Options > Deos > Dependencies
- math
- dart
- ansi
- printx
- You must add printx into your workspace, File >DDC-I Deos example project > training > printx
6. Edit $(PROJECT_DIR)/wolfsslPort/IDE/ECLIPSE/DEOS/user_setting.h to customize your configuration. For example, you can undef or define these tests.
-#undef NO_CRYPT_TEST
-#undef NO_CRYPT_BENCHMARK
-#undef NO_WOLFSSL_CLIENT
-#undef NO_WOLFSSL_SERVER
7. Edit your application source file where main() thread is defined and add the following:
You can modify the `TCP_SERVER_IP_ADDR` and `TCP_SERVER_PORT` macros in the `tls_wolfssl.c` file to configure the host address and port. You will also need to define the server certificate. The example client uses the GET request to get a web resource from the server at https://google.com.
### `wolfssl_server_test()`
You can modify the `TLS_SERVER_PORT` in the `tls_wolfssl.c` file to configure the port number to listen on a local-host.
Once you start the TLS server and `Listening for client connection` displays on the serial console, the server is ready to accept client connections.
You can connect to the server using the wolfssl TLS client example from your Linux or Windows host as follows:

2. Right click in the project exporer window and choose Inport.
3.Under General choose "Existing Projects into Workspace".
4. Under "Select root directory" click browse and select the wolfSSL root.
5.Check the "Search for nested projects" box.
5.Make sure "wolfssl" and "wolfssl_example" are checked under "Projects:".
6.Click finish.
7.Download the board and chip LPCOpen package for your platform.
8.Import the projects. For example "lpc_board_nxp_lpcxpresso_1837" and "lpc_chip_18xx" are the ones for the LPC18S37.
1.Change names of `LPCExpresso.project` and `LPCExpresso.cproject` files to `.project` and `.cproject`
2. Run LPCXpresso and choose a workspace location.
3.Right click in the project explorer window and choose Import.
4. Under General choose "Existing Projects into Workspace".
5.Under "Select root directory" click browse and select the wolfSSL root.
6.Check the "Search for nested projects" box.
7.Make sure "wolfssl" and "wolfssl_example" are checked under "Projects:".
8.Click finish.
9.Download the board and chip LPCOpen package for your platform.
10. Import the projects. For example "lpc_board_nxp_lpcxpresso_1837" and "lpc_chip_18xx" are the ones for the LPC18S37.
To setup this example to work with different baords/chips you will need to locate the LPCOpen sources for LPCXpresso on the NXP website and import the board and chip projects. Then you will need to update the "wolfssl_example" project properties to reference these projects (C/C++ General -> Paths and Symbols -> References). See the [LPCOpen v2.xx LPCXpresso quickstart guide for all platforms](https://www.lpcware.com/content/project/lpcopen-platform-nxp-lpc-microcontrollers/lpcopen-v200-quickstart-guides/lpcopen-1) for additional information.
