Version 3.6.13:
** libgnutls: Fix a DTLS-protocol regression (caused by TLS1.3 support), since 3.6.3.
The DTLS client would not contribute any randomness to the DTLS negotiation,
breaking the security guarantees of the DTLS protocol
[GNUTLS-SA-2020-03-31, CVSS: high]
** libgnutls: Added new APIs to access KDF algorithms.
** libgnutls: Added new callback gnutls_keylog_func that enables a custom
logging functionality.
** libgnutls: Added support for non-null terminated usernames in PSK
negotiation.
** gnutls-cli-debug: Improved support for old servers that only support
SSL 3.0.
** API and ABI modifications:
gnutls_hkdf_extract: Added
gnutls_hkdf_expand: Added
gnutls_pbkdf2: Added

Not sure of 3.6.11.1's specific changes - possibly fixing an incorrectly
generated tarball?
These changes from apply:
* Version 3.6.11 (released 2019-12-01)
** libgnutls: Use KERN_ARND for the system random number generator on NetBSD.
This syscall provides an endless stream of random numbers from the kernel's
ChaCha20-based random number generator, without blocking or requiring an open file
descriptor.
** libgnutls: Corrected issue with TLS 1.2 session ticket handling as client
during resumption (#841).
** libgnutls: gnutls_base64_decode2() succeeds decoding the empty string to
the empty string. This is a behavioral change of the API but it conforms
to the RFC4648 expectations (#834).
** libgnutls: Fixed AES-CFB8 implementation, when input is shorter than
the block size. Fix backported from nettle.
** certtool: CRL distribution points will be set in CA certificates even when
non self-signed (#765).
** gnutls-cli/serv: added raw public-key handling capabilities (RFC7250).
Key material can be set via the --rawpkkeyfile and --rawpkfile flags.
** API and ABI modifications:
No changes since last version.
* Version 3.6.10 (released 2019-09-29)
** libgnutls: Added support for deterministic ECDSA/DSA (RFC6979)
Deterministic signing can be enabled by setting
GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE when calling gnutls_privkey_sign_*()
functions (#94).
** libgnutls: add gnutls_aead_cipher_encryptv2 and gnutls_aead_cipher_decryptv2
functions that will perform in-place encryption/decryption on data buffers (#718).
** libgnutls: Corrected issue in gnutls_session_get_data2() which could fail under
TLS1.3, if a timeout callback was not set using gnutls_transport_set_pull_timeout_function()
(#823).
** libgnutls: added interoperability tests with gnutls 2.12.x; addressed
issue with large record handling due to random padding (#811).
** libgnutls: the server now selects the highest TLS protocol version,
if TLS 1.3 is enabled and the client advertises an older protocol version first (#837).
** libgnutls: fix non-PIC assembly on i386 (#818).
** libgnutls: added support for GOST 28147-89 cipher in CNT (GOST counter) mode
and MAC generation based on GOST 28147-89 (IMIT). For description of the
modes see RFC 5830. S-Box is id-tc26-gost-28147-param-Z (TC26Z) defined in
RFC 7836.
** certtool: when outputting an encrypted private key do not insert the textual description
of it. This fixes a regression since 3.6.5 (#840).
** API and ABI modifications:
gnutls_aead_cipher_encryptv2: Added
gnutls_aead_cipher_decryptv2: Added
GNUTLS_CIPHER_GOST28147_TC26Z_CNT: Added
GNUTLS_MAC_GOST28147_TC26Z_IMIT: Added
Fix compilation of gnutls with compilers missing __get_cpuid_count.
Taken from upstream and fixed in version 3.6.10 .
Fixes compilation on NetBSD 8 without setting GCC_REQD.
* Version 3.6.4 (released 2018-09-24)
** libgnutls: Added the final (RFC8446) version numbering of the TLS1.3 protocol.
** libgnutls: Corrected regression since 3.6.3 in the callbacks set with
gnutls_certificate_set_retrieve_function() which could not handle the case where
no certificates were returned, or the callbacks were set to NULL (see #528).
** libgnutls: gnutls_handshake() on server returns early on handshake when no
certificate is presented by client and the gnutls_init() flag GNUTLS_ENABLE_EARLY_START
is specified.
** libgnutls: Added session ticket key rotation on server side with TOTP.
The key set with gnutls_session_ticket_enable_server() is used as a
master key to generate time-based keys for tickets. The rotation
relates to the gnutls_db_set_cache_expiration() period.
** libgnutls: The 'record size limit' extension is added and preferred to the
'max record size' extension when possible.
** libgnutls: Provide a more flexible PKCS#11 search of trust store certificates.
This addresses the problem where the CA certificate doesn't have a subject key
identifier whereas the end certificates have an authority key identifier (#569)
** libgnutls: gnutls_privkey_export_gost_raw2(), gnutls_privkey_import_gost_raw(),
gnutls_pubkey_export_gost_raw2(), gnutls_pubkey_import_gost_raw() import
and export GOST parameters in the "native" little endian format used for these
curves. This is an intentional incompatible change with 3.6.3.
** libgnutls: Added support for seperately negotiating client and server certificate types
as defined in RFC7250. This mechanism must be explicitly enabled via the
GNUTLS_ENABLE_CERT_TYPE_NEG flag in gnutls_init().
** gnutls-cli: enable CRL validation on startup (#564)
** API and ABI modifications:
GNUTLS_ENABLE_EARLY_START: Added
GNUTLS_ENABLE_CERT_TYPE_NEG: Added
GNUTLS_TL_FAIL_ON_INVALID_CRL: Added
GNUTLS_CERTIFICATE_VERIFY_CRLS: Added
gnutls_ctype_target_t: New enumeration
gnutls_record_set_max_early_data_size: Added
gnutls_certificate_type_get2: Added
gnutls_priority_certificate_type_list2: Added
gnutls_ffdhe_6144_group_prime: Added
gnutls_ffdhe_6144_group_generator: Added
gnutls_ffdhe_6144_key_bits: Added
* Version 3.6.3 (released 2018-07-16)
** libgnutls: Introduced support for draft-ietf-tls-tls13-28. It includes version
negotiation, post handshake authentication, length hiding, multiple OCSP support,
consistent ciphersuite support across protocols, hello retry requests, ability
to adjust key shares via gnutls_init() flags, certificate authorities extension,
and key usage limits. TLS1.3 draft-28 support can be enabled by default if
the option --enable-tls13-support is given to configure script.
** libgnutls: Apply compatibility settings for existing applications running with TLS1.2 or
earlier and TLS 1.3. When SRP or NULL ciphersuites are specified in priority strings
TLS 1.3 is will be disabled. When Anonymous ciphersuites are specified in priority
strings, then TLS 1.3 negotiation will be disabled if the session is associated
only with an anonymous credentials structure.
** Added support for Russian Public Key Infrastructure according to RFCs 4491/4357/7836.
This adds support for using GOST keys for digital signatures and under PKCS#7, PKCS#12,
and PKCS#8 standards. In particular added elliptic curves GOST R 34.10-2001 CryptoProA
256-bit curve (RFC 4357), GOST R 34.10-2001 CryptoProXchA 256-bit curve (RFC 4357),
and GOST R 34.10-2012 TC26-512-A 512-bit curve (RFC 7836).
** Provide a uniform cipher list across supported TLS protocols; the CAMELLIA ciphers
as well as ciphers utilizing HMAC-SHA384 and SHA256 have been removed from the default
priority strings, as they are undefined under TLS1.3 and they provide not advantage
over other options in earlier protocols.
** The SSL 3.0 protocol is disabled on compile-time by default. It can be re-enabled
by specifying --enable-ssl3-support on configure script.
** libgnutls: Introduced function to switch the current FIPS140-2 operational
mode, i.e., strict vs a more lax mode which will allow certain non FIPS140-2
operations.
** libgnutls: Introduced low-level function to assist applications attempting client
hello extension parsing, prior to GnuTLS' parsing of the message.
** libgnutls: When exporting an X.509 certificate avoid re-encoding if there are no
modifications to the certificate. That prevents DER re-encoding issues with incorrectly
encoded certificates, or other DER incompatibilities to affect a TLS session.
Relates with #403
** libgnutls: on group exchange honor the %SERVER_PRECEDENCE and select the groups
which are preferred by the server. That unfortunately has complicated semantics
as TLS1.2 requires specific ordering of the groups based on the ciphersuite ordering,
which could make group order unpredictable if TLS1.3 is negotiated.
** Improved counter-measures for TLS CBC record padding. Kenny Paterson, Eyal Ronen
and Adi Shamir reported that the existing counter-measures had certain issues and
were insufficient when the attacker has additional access to the CPU cache and
performs a chosen-plaintext attack. This affected the legacy CBC ciphersuites. [CVSS: medium]
** Introduced the %FORCE_ETM priority string option. This option prevents the negotiation
of legacy CBC ciphersuites unless encrypt-then-mac is negotiated.
** libgnutls: gnutls_privkey_import_ext4() was enhanced with the
GNUTLS_PRIVKEY_INFO_PK_ALGO_BITS flag.
** libgnutls: gnutls_pkcs11_copy_secret_key, gnutls_pkcs11_copy_x509_privkey2,
gnutls_pkcs11_privkey_generate3 will mark objects as sensitive by default
unless GNUTLS_PKCS11_OBJ_FLAG_MARK_NOT_SENSITIVE is specified. This is an API
change for these functions which make them err towards safety.
** libgnutls: improved aarch64 cpu features detection by using getauxval().
** certtool: It is now possible to specify certificate and serial CRL numbers greater
than 2**63-2 as a hex-encoded string both when prompted and in a template file.
Default certificate serial numbers are now fully random. Default CRL
numbers include more random bits and are larger than in previous GnuTLS versions.
Since CRL numbers are required to be monotonic, specify suitable CRL numbers manually
if you intend to later downgrade to previous versions as it was not possible
to specify large CRL numbers in previous versions of certtool.
* Version 3.6.2 (released 2018-02-16)
** libgnutls: When verifying against a self signed certificate ignore issuer.
That is, ignore issuer when checking the issuer's parameters strength, resolving
issue #347 which caused self signed certificates to be additionally marked as of
insufficient security level.
** libgnutls: Corrected MTU calculation for the CBC ciphersuites. The data
MTU calculation now, it correctly accounts for the fixed overhead due to
padding (as 1 byte), while at the same time considers the rest of the
padding as part of data MTU.
** libgnutls: Address issue of loading of all PKCS#11 modules on startup
on systems with a PKCS#11 trust store (as opposed to a file trust store).
Introduced a multi-stage initialization which loads the trust modules, and
other modules are deferred for the first pure PKCS#11 request.
** libgnutls: The SRP authentication will reject any parameters outside
RFC5054. This protects any client from potential MitM due to insecure
parameters. That also brings SRP in par with the RFC7919 changes to
Diffie-Hellman.
** libgnutls: Added the 8192-bit parameters of SRP to the accepted parameters
for SRP authentication.
** libgnutls: Addressed issue in the accelerated code affecting interoperability
with versions of nettle >= 3.4.
** libgnutls: Addressed issue in the AES-GCM acceleration under aarch64.
** libgnutls: Addressed issue in the AES-CBC acceleration under ssse3 (patch by
Vitezslav Cizek).
** srptool: the --create-conf option no longer includes 1024-bit parameters.
** p11tool: Fixed the deletion of objects in batch mode.
** API and ABI modifications:
gnutls_srp_8192_group_generator: Added
gnutls_srp_8192_group_prime: Added
* Version 3.6.1 (released 2017-10-21)
** libgnutls: Fixed interoperability issue with openssl when safe renegotiation was
used. Resolves gitlab issue #259.
** libgnutls: gnutls_x509_crl_sign, gnutls_x509_crt_sign,
gnutls_x509_crq_sign, were modified to sign with a better algorithm than
SHA1. They will now sign with an algorithm that corresponds to the security
level of the signer's key.
** libgnutls: gnutls_x509_*_sign2() functions and gnutls_x509_*_privkey_sign()
accept GNUTLS_DIG_UNKNOWN (0) as a hash function option. That will signal
the function to auto-detect an appropriate hash algorithm to use.
** libgnutls: Removed support for signature algorithms using SHA2-224 in TLS.
TLS 1.3 no longer uses SHA2-224 and it was never a widespread algorithm
in TLS 1.2. As such, no reason to keep supporting it.
** libgnutls: Refuse to use client certificates containing disallowed
algorithms for a session. That reverts a change on 3.5.5, which allowed
a client to use DSA-SHA1 due to his old DSA certificate, without requiring him
to enable DSA-SHA1 (and thus make it acceptable for the server's certificate).
The previous approach was to allow a smooth move for client infrastructure
after the DSA algorithm became disabled by default, and is no longer necessary
as DSA is now being universally deprecated.
** libgnutls: Refuse to resume a session which had a different SNI advertised. That
improves RFC6066 support in server side. Reported by Thomas Klute.
** p11tool: Mark all generated objects as sensitive by default.
** p11tool: added options --sign-params and --hash. This allows testing
signature with multiple algorithms, including RSA-PSS.
** API and ABI modifications:
No changes since last version.
* Version 3.6.0 (released 2017-08-21)
** libgnutls: tlsfuzzer is part of the CI testsuite. This is a TLS testing and
fuzzying toolkit, allowing for corner case testing, and ensuring that the
behavior of the library will not change across releases.
https://github.com/tomato42/tlsfuzzer
** libgnutls: Introduced a lock-free random generator which operates per-thread
and eliminates random-generator related bottlenecks in multi-threaded operation.
Resolves gitlab issue #141.
http://nmav.gnutls.org/2017/03/improving-by-simplifying-gnutls-prng.html
** libgnutls: Replaced the Salsa20 random generator with one based on CHACHA.
The goal is to reduce code needed in cache (CHACHA is also used for TLS),
and the number of primitives used by the library. That does not affect the
AES-DRBG random generator used in FIPS140-2 mode.
** libgnutls: Added support for RSA-PSS key type as well as signatures in
certificates, and TLS key exchange. Contributed by Daiki Ueno.
RSA-PSS signatures can be generated by RSA-PSS keys and normal RSA keys,
but not vice-versa. The feature includes:
* RSA-PSS key generation and key handling (in PKCS#8 form)
* RSA-PSS key generation and key handling from PKCS#11 (with CKM_RSA_PKCS_PSS mech)
* Handling of RSA-PSS subjectPublicKeyInfo parameters, when present
in either the private key or certificate.
* RSA-PSS signing and verification of PKIX certificates
* RSA-PSS signing and verification of TLS 1.2 handshake
* RSA-PSS signing and verification of PKCS#7 structures
* RSA-PSS and RSA key combinations for TLS credentials. That is, when
multiple keys are supplied, RSA-PSS keys are preferred over RSA for RSA-PSS
TLS signatures, to contain risks of cross-protocol attacks between the algorithms.
* RSA-PSS key conversion to RSA PKCS#1 form (certtool --to-rsa)
Note that RSA-PSS signatures with SHA1 are (intentionally) not supported.
** libgnutls: Added support for Ed25519 signing in certificates and TLS key
exchange following draft-ietf-tls-rfc4492bis-17. The feature includes:
* Ed25519 key generation and key handling (in PKCS#8 form)
* Ed25519 signing and verification of PKIX certificates
* Ed25519 signing and verification of TLS 1.2 handshake
* Ed25519 signing and verification of PKCS#7 structures
** libgnutls: Enabled X25519 key exchange by default, following draft-ietf-tls-rfc4492bis-17.
** libgnutls: Added support for Diffie-Hellman group negotiation following RFC7919.
That makes the DH parameters negotiation more robust and less prone to errors
due to insecure parameters. Servers are no longer required to specific explicit
DH parameters, though if they do these parameters will be used. Group
selection can be done via priority strings. The introduced strings are
GROUP-ALL, GROUP-FFDHE2048, GROUP-FFDHE3072, GROUP-FFDHE4096 and
GROUP-FFDHE8192, as well as the corresponding to curves groups. Note that
the 6144 group from RFC7919 is not supported.
** libgnutls: Introduced various sanity checks on certificate import. Refuse
to import certificates which have fractional seconds in Time fields, X.509v1
certificates which have the unique identifiers set, and certificates with illegal
version numbers. All of these are prohibited by RFC5280.
** libgnutls: Introduced gnutls_x509_crt_set_flags(). This function can set flags
in the crt structure. The only flag supported at the moment is
GNUTLS_X509_CRT_FLAG_IGNORE_SANITY which skips the certificate sanity
checks on import.
** libgnutls: PKIX certificates with unknown critical extensions are rejected
on verification with status GNUTLS_CERT_UNKNOWN_CRIT_EXTENSIONS. This
behavior can be overriden by providing the flag GNUTLS_VERIFY_IGNORE_UNKNOWN_CRIT_EXTENSIONS
to verification functions. Resolves gitlab issue #177.
** libgnutls: Refuse to generate a certificate with an illegal version, or an
illegal serial number. That is, gnutls_x509_crt_set_version() and
gnutls_x509_crt_set_serial(), will fail on input considered to be invalid
in RFC5280.
** libgnutls: Calls to gnutls_record_send() and gnutls_record_recv()
prior to handshake being complete are now refused. Addresses gitlab issue #158.
** libgnutls: Added support for PKCS#12 files with no salt (zero length) in their
password encoding, and PKCS#12 files using SHA384 and SHA512 as MAC.
** libgnutls: Exported functions to encode and decode DSA and ECDSA r,s values.
** libgnutls: Added new callback setting function to gnutls_privkey_t for external
keys. The new function (gnutls_privkey_import_ext4), allows signing in addition
to previous algorithms (RSA PKCS#1 1.5, DSA, ECDSA), with RSA-PSS and Ed25519
keys.
** libgnutls: Introduced the %VERIFY_ALLOW_BROKEN and %VERIFY_ALLOW_SIGN_WITH_SHA1
priority string options. These allows enabling all broken and SHA1-based signature
algorithms in certificate verification, respectively.
** libgnutls: 3DES-CBC is no longer included in the default priorities
list. It has to be explicitly enabled, e.g., with a string like
"NORMAL:+3DES-CBC".
** libgnutls: SHA1 was marked as insecure for signing certificates. Verification
of certificates signed with SHA1 is now considered insecure and will
fail, unless flags intended to enable broken algorithms are set. Other uses
of SHA1 are still allowed. This can be reverted on compile time with the configure
flag --enable-sha1-support.
** libgnutls: RIPEMD160 was marked as insecure for certificate signatures. Verification
of certificates signed with RIPEMD160 hash algorithm is now considered insecure and
will fail, unless flags intended to enable broken algorithms are set.
** libgnutls: No longer enable SECP192R1 and SECP224R1 by default on TLS handshakes.
These curves were rarely used for that purpose, provide no advantage over
x25519 and were deprecated by TLS 1.3.
** libgnutls: Removed support for DEFLATE, or any other compression method.
** libgnutls: OpenPGP authentication was removed; the resulting library is ABI
compatible, with the openpgp related functions being stubs that fail
on invocation.
** libgnutls: Removed support for libidn (i.e., IDNA2003); gnutls can now be compiled
only with libidn2 which provides IDNA2008.
** certtool: The option '--load-ca-certificate' can now accept PKCS#11
URLs in addition to files.
** certtool: The option '--load-crl' can now be used when generating PKCS#12
files (i.e., in conjunction with '--to-p12' option).
** certtool: Keys with provable RSA and DSA parameters are now only read and
exported from PKCS#8 form, following draft-mavrogiannopoulos-pkcs8-validated-parameters-00.txt.
This removes support for the previous a non-standard key format.
** certtool: Added support for generating, printing and handling RSA-PSS and
Ed25519 keys and certificates.
** certtool: the parameters --rsa, --dsa and --ecdsa to --generate-privkey are now
deprecated, replaced by the --key-type option.
** p11tool: The --generate-rsa, --generate-ecc and --generate-dsa options were
replaced by the --generate-privkey option.
** psktool: Generate 256-bit keys by default.
** gnutls-server: Increase request buffer size to 16kb, and added the --alpn and
--alpn-fatal options, allowing testing of ALPN negotiation.
** API and ABI modifications:

* Version 3.5.8 (released 2016-01-09)
** libgnutls: Ensure that multiple calls to the gnutls_set_priority_*
functions will not leave the verification profiles field to an
undefined state. The last call will take precedence.
** libgnutls: Ensure that GNUTLS_E_DECRYPTION_FAIL will be returned
by PKCS#8 decryption functions when an invalid key is provided. This
addresses regression on decrypting certain PKCS#8 keys.
** libgnutls: Introduced option to override the default priority string
used by the library. The intention is to allow support of system-wide
priority strings (as set with --with-system-priority-file). The
configure option is --with-default-priority-string.
** libgnutls: Require a valid IV size on all ciphers for PKCS#8 decryption.
This prevents crashes when decrypting malformed PKCS#8 keys.
** libgnutls: Fix crash on the loading of malformed private keys with certain
parameters set to zero.
** libgnutls: Fix double free in certificate information printing. If the PKIX
extension proxy was set with a policy language set but no policy specified,
that could lead to a double free.
** libgnutls: Addressed memory leaks in client and server side error paths
(issues found using oss-fuzz project)
** libgnutls: Addressed memory leaks in X.509 certificate printing error paths
(issues found using oss-fuzz project)
** libgnutls: Addressed memory leaks and an infinite loop in OpenPGP certificate
parsing. Fixes by Alex Gaynor. (issues found using oss-fuzz project)
** libgnutls: Addressed invalid memory accesses in OpenPGP certificate parsing.
(issues found using oss-fuzz project)
** API and ABI modifications:
No changes since last version.
* Version 3.5.7 (released 2016-12-8)
** libgnutls: Include CHACHA20-POLY1305 ciphersuites in the SECURE128
and SECURE256 priority strings.
** libgnutls: Require libtasn1 4.9; this ensures gnutls will correctly
operate with OIDs which have elements that exceed 2^32.
** libgnutls: The DN decoding functions output the traditional DN format
rather than the strict RFC4514 compliant textual DN. This reverts the
3.5.6 introduced change, and allows applications which depended on the
previous format to continue to function. Introduced new functions which
output the strict format by default, and can revert to the old one using
a flag.
** libgnutls: Improved TPM key handling. Check authorization requirements
prior to using a key and fix issue on loop for PIN input. Patches by
James Bottomley.
** libgnutls: In all functions accepting UTF-8 passwords, ensure that
passwords are normalized according to RFC7613. When invalid UTF-8
passwords are detected, they are only tolerated for decryption.
This introduces a libunistring dependency on GnuTLS. A version of
libunistring is included in the library for the platforms that do
not ship it; it can be used with the '--with-included-unistring'
option to configure script.
** libgnutls: When setting a subject alternative name in a certificate
which is in UTF-8 format, it will transparently be converted to IDNA form
prior to storing.
** libgnutls: GNUTLS_CRT_PRINT_ONELINE flag on gnutls_x509_crt_print()
will print the SHA256 key-ID instead of a certificate fingerprint.
** libgnutls: enhance the PKCS#7 verification capabilities. In the case
signers that are not discoverable using the trust list or input, use
the stored list as pool to generate a trusted chain to the signer.
** libgnutls: Improved MTU calculation precision for the CBC ciphersuites
under DTLS.
** libgnutls: [added missing news entry since 3.5.0]
No longer tolerate certificate key usage violations for
TLS signature verification, and decryption. That is GnuTLS will fail
to connect to servers which incorrectly use a restricted to signing certificate
for decryption, or vice-versa. This reverts the lax behavior introduced
in 3.1.0, due to several such broken servers being available. The %COMPAT
priority keyword can be used to work-around connecting on these servers.
** certtool: When exporting a CRQ in DER format ensure no text data are
intermixed. Patch by Dmitry Eremin-Solenikov.
** certtool: Include the SHA-256 variant of key ID in --certificate-info
options.
** p11tool: Introduced the --initialize-pin and --initialize-so-pin
options.
** API and ABI modifications:
gnutls_utf8_password_normalize: Added
gnutls_ocsp_resp_get_responder2: Added
gnutls_x509_crt_get_issuer_dn3: Added
gnutls_x509_crt_get_dn3: Added
gnutls_x509_rdn_get2: Added
gnutls_x509_dn_get_str2: Added
gnutls_x509_crl_get_issuer_dn3: Added
gnutls_x509_crq_get_dn3: Added
* Version 3.5.6 (released 2016-11-04)
** libgnutls: Enhanced the PKCS#7 parser to allow decoding old
(pre-rfc5652) structures with arbitrary encapsulated content.
** libgnutls: Introduced a function group to set known DH parameters
using groups from RFC7919.
** libgnutls: Added more strict RFC4514 textual DN encoding and decoding.
Now the generated textual DN is in reverse order according to RFC4514,
and functions which generate a DN from strings such gnutls_x509_crt_set_*dn()
set the expected DN (reverse of the provided string).
** libgnutls: Introduced time and constraints checks in the end certificate
in the gnutls_x509_crt_verify_data2() and gnutls_pkcs7_verify_direct()
functions.
** libgnutls: Set limits on the maximum number of alerts handled. That is,
applications using gnutls could be tricked into an busy loop if the
peer sends continuously alert messages. Applications which set a maximum
handshake time (via gnutls_handshake_set_timeout) will eventually recover
but others may remain in a busy loops indefinitely. This is related but
not identical to CVE-2016-8610, due to the difference in alert handling
of the libraries (gnutls delegates that handling to applications).
** libgnutls: Reverted the change which made the gnutls_certificate_set_*key*
functions return an index (introduced in 3.5.5), to avoid affecting programs
which explicitly check success of the function as equality to zero. In order
for these functions to return an index an explicit call to gnutls_certificate_set_flags
with the GNUTLS_CERTIFICATE_API_V2 flag is now required.
** libgnutls: Reverted the behavior of sending a status request extension even
without a response (introduced in 3.5.5). That is, we no longer reply to a
client's hello with a status request, with a status request extension. Although
that behavior is legal, it creates incompatibility issues with releases in
the gnutls 3.3.x branch.
** libgnutls: Delayed the initialization of the random generator at
the first call of gnutls_rnd(). This allows applications to load
on systems which getrandom() would block, without blocking until
real random data are needed.
** certtool: --get-dh-params will output parameters from the RFC7919
groups.
** p11tool: improvements in --initialize option.
** API and ABI modifications:
GNUTLS_CERTIFICATE_API_V2: Added
GNUTLS_NO_TICKETS: Added
gnutls_pkcs7_get_embedded_data_oid: Added
gnutls_anon_set_server_known_dh_params: Added
gnutls_certificate_set_known_dh_params: Added
gnutls_psk_set_server_known_dh_params: Added
gnutls_x509_crt_check_key_purpose: Added
* Version 3.5.5 (released 2016-10-09)
** libgnutls: enhanced gnutls_certificate_set_ocsp_status_request_file()
to allow importing multiple OCSP request files, one for each chain
provided.
** libgnutls: The gnutls_certificate_set_key* functions return an
index of the added chain. That index can be used either with
gnutls_certificate_set_ocsp_status_request_file(), or with
gnutls_certificate_get_crt_raw() and friends.
** libgnutls: Added SHA*, AES-GCM, AES-CCM and AES-CBC optimized implementations
for the aarch64 architecture. Uses Andy Polyakov's assembly code.
** libgnutls: Ensure proper cleanups on gnutls_certificate_set_*key()
failures due to key mismatch. This prevents leaks or double freeing
on such failures.
** libgnutls: Increased the maximum size of the handshake message hash.
This will allow the library to cope better with larger packets, as
the ones offered by current TLS 1.3 drafts.
** libgnutls: Allow to use client certificates despite them containing
disallowed algorithms for a session. That allows for example a client
to use DSA-SHA1 due to his old DSA certificate, without requiring him
to enable DSA-SHA1 (and thus make it acceptable for the server's certificate).
** libgnutls: Reverted AESNI code on x86 to earlier version as the
latest version was creating position depending code. Added checks
in the CI to detect position depending code early.
** guile: Update code to the I/O port API of Guile >= 2.1.4
This makes sure the GnuTLS bindings will work with the forthcoming 2.2
stable series of Guile, of which 2.1 is a preview.
** API and ABI modifications:
gnutls_certificate_set_ocsp_status_request_function2: Added
gnutls_session_ext_register: Added
gnutls_session_supplemental_register: Added
GNUTLS_E_PK_INVALID_PUBKEY: Added
GNUTLS_E_PK_INVALID_PRIVKEY: Added
* Version 3.5.4 (released 2016-09-08)
** libgnutls: Corrected the comparison of the serial size in OCSP response.
Previously the OCSP certificate check wouldn't verify the serial length
and could succeed in cases it shouldn't (GNUTLS-SA-2016-3).
Reported by Stefan Buehler.
** libgnutls: Added support for IP name constraints. Patch by Martin Ukrop.
** libgnutls: Added support of PKCS#8 file decryption using DES-CBC-MD5. This
is added to allow decryption of PKCS #8 private keys from openssl prior to 1.1.0.
** libgnutls: Added support for decrypting PKCS#8 files which use HMAC-SHA256
as PRF. This allow decrypting PKCS #8 private keys generated with openssl 1.1.0.
** libgnutls: Added support for internationalized passwords in PKCS#12 files.
Previous versions would only encrypt or decrypt using passwords from the ASCII
set.
** libgnutls: Addressed issue with PKCS#11 signature generation on ECDSA
keys. The signature is now written as unsigned integers into the DSASignatureValue
structure. Previously signed integers could be written depending on what
the underlying module would produce. Addresses #122.
** gnutls-cli: Fixed starttls regression from 3.5.3.
** API and ABI modifications:
GNUTLS_E_MALFORMED_CIDR: Added
gnutls_x509_cidr_to_rfc5280: Added
gnutls_oid_to_mac: Added
* Version 3.5.3 (released 2016-08-09)
** libgnutls: Added support for TCP fast open (RFC7413), allowing
to reduce by one round-trip the handshake process. Based on proposal and
patch by Tim Ruehsen.
** libgnutls: Adopted a simpler with less memory requirements DTLS sliding
window implementation. Based on Fridolin Pokorny's implementation for
AF_KTLS.
** libgnutls: Use getrandom where available via the syscall interface.
This works around an issue of not-using getrandom even if it exists
since glibc doesn't declare such function.
** libgnutls: Fixed DNS name constraints checking in the case of empty
intersection of domain names in the chain. Report and fix by Martin Ukrop.
** libgnutls: Fixed name constraints checking in the case of chains
where the higher level certificates contained different types of
constraints than the ones present in the lower intermediate CAs.
Report and fix by Martin Ukrop.
** libgnutls: Dropped support for the EGD random generator.
** libgnutls: Allow the decoding of raw elements (starting with #)
in RFC4514 DN string decoding.
** libgnutls: Fixes in gnutls_x509_crt_list_import2, which was
ignoring flags if all certificates in the list fit within the
initially allocated memory. Patch by Tim Kosse.
** libgnutls: Corrected issue which made gnutls_certificate_get_x509_crt()
to return invalid pointers when returned more than a single certificate.
Report and fix by Stefan Sørensen.
** libgnutls: Fix gnutls_pkcs12_simple_parse to always extract the complete chain,
even when the extra_certs was non-null. Report and fix by Stefan Sørensen.
** certtool: Added the "add_extension" and "add_critical_extension"
template options. This allows specifying arbitrary extensions into
certificates and certificate requests.
** gnutls-cli: Added the --fastopen option.
** API and ABI modifications:
GNUTLS_E_UNAVAILABLE_DURING_HANDSHAKE: Added
gnutls_x509_crq_set_extension_by_oid: Added
gnutls_x509_dn_set_str: Added
gnutls_transport_set_fastopen: Added
* Version 3.5.2 (released 2016-07-06)
** libgnutls: Address issue when utilizing the p11-kit trust store
for certificate verification (GNUTLS-SA-2016-2).
** libgnutls: Fixed DTLS handshake packet reconstruction. Reported by
Guillaume Roguez.
** libgnutls: Fixed issues with PKCS#11 reading of sensitive objects
from SafeNet Network HSM. Reported by Anthony Alba in #108.
** libgnutls: Corrected the writing of PKCS#11 CKA_SERIAL_NUMBER. Report
and fix by Stanislav Židek.
** libgnutls: Added AES-GCM optimizations using the AVX and MOVBE
instructions. Uses Andy Polyakov's assembly code.
** API and ABI modifications:
No changes since last version.
* Version 3.5.1 (released 2016-06-14)
** libgnutls: The SSL 3.0 protocol support can completely be removed
using a compile time option. The configure option is --disable-ssl3-support.
** libgnutls: The SSL 2.0 client hello support can completely be removed
using a compile time option. The configure option is --disable-ssl2-support.
** libgnutls: Added support for OCSP Must staple PKIX extension. That is,
implemented the RFC7633 TLSFeature for OCSP status request extension.
Feature implemented by Tim Kosse.
** libgnutls: More strict OCSP staple verification. That is, no longer
ignore invalid or too old OCSP staples. The previous behavior was
to rely on application use gnutls_ocsp_status_request_is_checked(),
while the new behavior is to include OCSP verification by default
and set the GNUTLS_CERT_INVALID_OCSP_STATUS verification flag on error.
** libgnutls: Treat CA certificates with the "Server Gated Cryptography" key
purpose OIDs equivalent to having the GNUTLS_KP_TLS_WWW_SERVER OID. This
improves interoperability with several old intermediate CA certificates
carrying these legacy OIDs.
** libgnutls: Re-read the system wide priority file when needed. Patch by
Daniel P. Berrange.
** libgnutls: Allow for fallback in system-specific initial keywords
(prefixed with '@'). That allows to specify a keyword such as
"@KEYWORD1,KEYWORD2" which will use the first available of these
two keywords. Patch by Daniel P. Berrange.
** libgnutls: The SSLKEYLOGFILE environment variable can be used to log
session keys. These session keys are compatible with the NSS Key Log
Format and can be used to decrypt the session for debugging using
wireshark.
** API and ABI modifications:
GNUTLS_CERT_INVALID_OCSP_STATUS: Added
gnutls_x509_crt_set_crq_extension_by_oid: Added
gnutls_x509_ext_import_tlsfeatures: Added
gnutls_x509_ext_export_tlsfeatures: Added

gnutls_x509_crq_set_tlsfeatures: Added
gnutls_ext_get_name: Added
* Version 3.5.0 (released 2016-05-09)
** libgnutls: Added SHA3 based signing algorithms for DSA, RSA and ECDSA,
based on http://csrc.nist.gov/groups/ST/crypto_apps_infra/csor/algorithms.html
** libgnutls: Added support for curve X25519 (RFC 7748, draft-ietf-tls-rfc4492bis-07).
This curve is disabled by default as it is still on specification status. It
can be enabled using the priority string modifier +CURVE-X25519.
** libgnutls: Added support for TLS false start (draft-ietf-tls-falsestart-01)
by introducing gnutls_init() flag GNUTLS_ENABLE_FALSE_START (#73).
** libgnutls: Added new APIs to access the FIPS186-4 (Shawe-Taylor based) provable
RSA and DSA parameter generation from a seed.
** libgnutls: The CHACHA20-POLY1305 ciphersuite is enabled by default. This
cipher is prioritized after AES-GCM.
** libgnutls: On a rehandshake ensure that the certificate of the peer or
its username remains the same as in previous handshakes. That is to protect
applications which do not check user credentials on rehandshakes. The
threat to address depends on the application protocol. Primarily it
protects against applications which authenticate the peer initially and
perform accounting using the session's information, from being misled
by a rehandshake which switches the peer's identity. Applications can
disable this protection by using the %GNUTLS_ALLOW_ID_CHANGE flag in
gnutls_init().
** libgnutls: Be strict in TLS extension decoding. That is, do not tolerate
parsing errors in the extensions field and treat it as a typical Hello
message structure. Reported by Hubert Kario (#40).
** libgnutls: Old and unsupported version numbers in client hellos are
rejected with a "protocol_version" alert message. Reported by Hubert
Kario (#42).
** libgnutls: Lifted the limitation of calling the gnutls_session_get_data*()
functions, only on non-resumed sessions. This brings the API in par with
its usage (#79).
** libgnutls: Follow RFC5280 strictly in name constraints computation. The
permitted subtrees is intersected with any previous values. Report and
patch by Daiki Ueno.
** libgnutls: Enforce the RFC 7627 (extended master secret) requirements on
session resumption. Reported by Hubert Kario (#69).
** libgnutls: Consider the max-record TLS extension even when under DTLS.
Reported by Peter Dettman (#61).
** libgnutls: Replaced writev() system call with sendmsg().
** libgnutls: Replaced select() system call with poll() on POSIX systems.
** libgnutls: Preload the system priority file on library load. This allows
applications that chroot() to also use the system priorities.
** libgnutls: Applications are allowed to override the built-in key and
certificate URLs.
** libgnutls: The gnutls.h header marks constant and pure functions explictly.
** certtool: Added the ability to sign certificates using SHA3.
** certtool: Added the --provable and --verify-allow-broken options.
** gnutls-cli: The --dane option will cause verification failure if gnutls is not
compiled with DANE support.
** crywrap: The tool was unbundled from gnutls' distribution. It can be found at
https://github.com/nmav/crywrap
** guile: .go files are now built and installed
** guile: Fix compatibility issue of the test suite with Guile 2.1
** guile: When --with-guile-site-dir is passed, modules are installed in a
versioned directory, typically $(datadir)/guile/site/2.0
** guile: Tests no longer leave zombie processes behind

* Version 3.4.3 (released 2015-07-12)
** libgnutls: Follow closely RFC5280 recommendations and use UTCTime for
dates prior to 2050.
** libgnutls: Force 16-byte alignment to all input to ciphers (previously it
was done only when cryptodev was enabled).
** libgnutls: Removed support for pthread_atfork() as it has undefined
semantics when used with dlopen(), and may lead to a crash.
** libgnutls: corrected failure when importing plain files
with gnutls_x509_privkey_import2(), and a password was provided.
** libgnutls: Don't reject certificates if a CA has the URI or IP address
name constraints, and the end certificate doesn't have an IP address
name or a URI set.
** libgnutls: set and read the hint in DHE-PSK and ECDHE-PSK ciphersuites.
** p11tool: Added --list-token-urls option, and print the token module name
in list-tokens.

* Version 3.4.2 (released 2015-06-16)
** libgnutls: DTLS blocking API is more robust against infinite blocking,
and will notify of more possible timeouts.
** libgnutls: corrected regression with Camellia-256-GCM cipher. Reported
by Manuel Pegourie-Gonnard.
** libgnutls: Introduced the GNUTLS_NO_SIGNAL flag to gnutls_init(). That
allows to disable SIGPIPE for writes done within gnutls.
** libgnutls: Enhanced the PKCS #7 API to allow signing and verification
of structures. API moved to gnutls/pkcs7.h header.
** certtool: Added options to generate PKCS #7 bundles and signed
structures.
** API and ABI modifications:
gnutls_x509_dn_get_str: Added

* Version 3.4.1 (released 2015-05-03)
** libgnutls: gnutls_certificate_get_ours: will return the certificate even
if a callback was used to send it.
** libgnutls: Check for invalid length in the X.509 version field. Without
the check certificates with invalid length would be detected as having an
arbitrary version. Reported by Hanno Böck.
** libgnutls: Handle DNS name constraints with a leading dot. Patch by
Fotis Loukos.
** libgnutls: Updated system-keys support for windows to compile in more
versions of mingw. Patch by Tim Kosse.
** libgnutls: Fix for MD5 downgrade in TLS 1.2 signatures. Reported by
Karthikeyan Bhargavan [GNUTLS-SA-2015-2].
** libgnutls: Reverted: The gnutls_handshake() process will enforce a timeout
by default. That caused issues with non-blocking programs.
** certtool: It can generate SHA256 key IDs.
** gnutls-cli: fixed crash in --benchmark-ciphers. Reported by James Cloos.
** configure: re-enabled the --enable-local-libopts flag
** API and ABI modifications:
gnutls_x509_crt_get_pk_ecc_raw: Added
* Version 3.4.0 (released 2015-04-08)
** libgnutls: Added support for AES-CCM and AES-CCM-8 (RFC6655 and RFC7251)
ciphersuites. The former are enabled by default, the latter need to be
explicitly enabled, since they reduce the overall security level.
** libgnutls: Added support for Chacha20-Poly1305 ciphersuites following
draft-mavrogiannopoulos-chacha-tls-05 and draft-irtf-cfrg-chacha20-poly1305-10.
That is currently provided as technology preview and is not enabled by
default, since there are no assigned ciphersuite points by IETF and there
is no guarrantee of compatibility between draft versions. The ciphersuite
priority string to enable it is "+CHACHA20-POLY1305".
** libgnutls: Added support for encrypt-then-authenticate in CBC
ciphersuites (RFC7366 -taking into account its errata text). This is
enabled by default and can be disabled using the %NO_ETM priority
string.
** libgnutls: Added support for the extended master secret
(triple-handshake fix) following draft-ietf-tls-session-hash-02.
** libgnutls: Added a new simple and hard to misuse AEAD API (crypto.h).
** libgnutls: SSL 3.0 is no longer included in the default priorities
list. It has to be explicitly enabled, e.g., with a string like
"NORMAL:+VERS-SSL3.0".
** libgnutls: ARCFOUR (RC4) is no longer included in the default priorities
list. It has to be explicitly enabled, e.g., with a string like
"NORMAL:+ARCFOUR-128".
** libgnutls: DSA signatures and DHE-DSS are no longer included in the
default priorities list. They have to be explicitly enabled, e.g., with
a string like "NORMAL:+DHE-DSS:+SIGN-DSA-SHA256:+SIGN-DSA-SHA1". The
DSA ciphersuites were dropped because they had no deployment at all
on the internet, to justify their inclusion.
** libgnutls: The priority string EXPORT was completely removed. The string
was already defunc as support for the EXPORT ciphersuites was removed in
GnuTLS 3.2.0.
** libgnutls: Added API to utilize system specific private keys in
"gnutls/system-keys.h". It is currently provided as technology preview
and is restricted to windows CNG keys.
** libgnutls: gnutls_x509_crt_check_hostname() and friends will use
RFC6125 comparison of hostnames. That introduces a dependency on libidn.
** libgnutls: Depend on p11-kit 0.23.1 to comply with the final
PKCS #11 URLs draft (draft-pechanec-pkcs11uri-21).
** libgnutls: Depend on nettle 3.1.
** libgnutls: Use getrandom() or getentropy() when available. That
avoids the complexity of file descriptor handling and issues with
applications closing all open file descriptors on startup.
** libgnutls: Use pthread_atfork() to detect fork when available.
** libgnutls: If a key purpose (extended key usage) is specified for verification,
it is applied into intermediate certificates. The verification result
GNUTLS_CERT_PURPOSE_MISMATCH is also introduced.
** libgnutls: When gnutls_certificate_set_x509_key_file2() is used in
combination with PKCS #11, or TPM URLs, it will utilize the provided
password as PIN if required. That removes the requirement for the
application to set a callback for PINs in that case.
** libgnutls: priority strings VERS-TLS-ALL and VERS-DTLS-ALL are
restricted to the corresponding protocols only, and the VERS-ALL
string is introduced to catch all possible protocols.
** libgnutls: Added helper functions to obtain information on PKCS #8
structures.
** libgnutls: Certificate chains which are provided to gnutls_certificate_credentials_t
will automatically be sorted instead of failing with GNUTLS_E_CERTIFICATE_LIST_UNSORTED.
** libgnutls: Added functions to export and set the record state. That
allows for gnutls_record_send() and recv() to be offloaded (to kernel,
hardware or any other subsystem).
** libgnutls: Added the ability to register application specific URL
types, which express certificates and keys using gnutls_register_custom_url().
** libgnutls: Added API to override existing ciphers, digests and MACs, e.g.,
to override AES-GCM using a system-specific accelerator. That is, (crypto.h)
gnutls_crypto_register_cipher(), gnutls_crypto_register_aead_cipher(),
gnutls_crypto_register_mac(), and gnutls_crypto_register_digest().
** libgnutls: Added gnutls_ext_register() to register custom extensions.
Contributed by Thierry Quemerais.
** libgnutls: Added gnutls_supplemental_register() to register custom
supplemental data handshake messages. Contributed by Thierry Quemerais.
** libgnutls-openssl: it is no longer built by default.
** certtool: Added --p8-info option, which will print PKCS #8 information
even if the password is not available.
** certtool: --key-info option will print PKCS #8 encryption information
when available.
** certtool: Added the --key-id and --fingerprint options.
** certtool: Added the --verify-hostname, --verify-email and --verify-purpose
options to be used in certificate chain verification, to simulate verification
for specific hostname and key purpose (extended key usage).
** certtool: --p12-info option will print PKCS #12 MAC and cipher information
when available.
** certtool: it will print the A-label (ACE) names in addition to UTF-8.
** p11tool: added options --set-id and --set-label.
** gnutls-cli: added options --priority-list and --save-cert.
** guile: Deprecated priority API has been removed. The old priority API,
which had been deprecated for some time, is now gone; use 'set-session-priorities!'
instead.
** guile: Remove RSA parameters and related procedures. This API had been
deprecated.
** guile: Fix compilation on MinGW. Previously only the static version of the
'guile-gnutls-v-2' library would be built, preventing dynamic loading from Guile.

** libgnutls: Fix issue with server side sending the status request
extension even when not requested. Reported by Jeremy Harris.
** libgnutls: gnutls_pkcs11_privkey_generate2() will store the generated
public key, unless the GNUTLS_PKCS11_OBJ_FLAG_NO_STORE_PUBKEY flag is
specified.
** libgnutls: fixed double free in DN decoding [GNUTLS-SA-2015-3].
** API and ABI modifications:
No changes since last version.
* Version 3.3.16 (released 2015-07-12)
** libgnutls: Allow compilation with nettle 3.0 or later
** libgnutls: corrected failure when importing plain files
with gnutls_x509_privkey_import2(), and a password was provided.
** libgnutls: Don't reject certificates if a CA has the URI or IP address
name constraints, and the end certificate doesn't have an IP address
name or a URI set.
** libgnutls: set and read the hint in DHE-PSK and ECDHE-PSK ciphersuites.
** API and ABI modifications:
No changes since last version.
patch refresh grace of mkpatches
upstream notable changes list since the 3.2 to 3.3 branch point (excerpt
of the NEWS file):
* Version 3.3.15 (released 2015-05-03)
** libgnutls: gnutls_certificate_get_ours: will return the certificate even
if a callback was used to send it.
** libgnutls: Fix for MD5 downgrade in TLS 1.2 signatures. Reported by
Karthikeyan Bhargavan [GNUTLS-SA-2015-2].
** libgnutls: Check for invalid length in the X.509 version field. Without the check
certificates with invalid length would be detected as having an arbitrary
version. Reported by Hanno Böck.
** API and ABI modifications:
No changes since last version.
* Version 3.3.14 (released 2015-03-30)
** libgnutls: When retrieving OCTET STRINGS from PKCS #12 ContentInfo
structures use BER to decode them (requires libtasn1 4.3). That allows
to decode some more complex structures.
** libgnutls: When an end-certificate with no name is present and there
are CA name constraints, don't reject the certificate. This follows RFC5280
advice closely. Reported by Fotis Loukos.
** libgnutls: Fixed handling of supplemental data with types > 255.
Patch by Thierry Quemerais.
** libgnutls: Fixed double free in the parsing of CRL distribution points certificate
extension. Reported by Robert Święcki.
** libgnutls: Fixed a two-byte stack overflow in DTLS 0.9 protocol. That
protocol is not enabled by default (used by openconnect VPN).
** libgnutls: The maximum user data send size is set to be the same for
block and non-block ciphersuites. This addresses a regression with wine:
https://bugs.winehq.org/show_bug.cgi?id=37500
** libgnutls: When generating PKCS #11 keys, set CKA_ID, CKA_SIGN,
and CKA_DECRYPT when needed.
** libgnutls: Allow names with zero size to be set using
gnutls_server_name_set(). That will disable the Server Name Indication.
Resolves issue with wine: https://gitlab.com/gnutls/gnutls/issues/2
** API and ABI modifications:
No changes since last version.
* Version 3.3.13 (released 2015-02-25)
** libgnutls: Enable AESNI in GCM on x86
** libgnutls: Fixes in DTLS message handling
** libgnutls: Check certificate algorithm consistency, i.e.,
check whether the signatureAlgorithm field matches the signature
field inside TBSCertificate.
** gnutls-cli: Fixes in OCSP verification.
** API and ABI modifications:
No changes since last version.
* Version 3.3.12 (released 2015-01-17)
** libgnutls: When negotiating TLS use the lowest enabled version in
the client hello, rather than the lowest supported. In addition, do
not use SSL 3.0 as a version in the TLS record layer, unless SSL 3.0
is the only protocol supported. That addresses issues with servers that
immediately drop the connection when the encounter SSL 3.0 as the record
version number. See:
http://lists.gnutls.org/pipermail/gnutls-help/2014-November/003673.html
** libgnutls: Corrected encoding and decoding of ANSI X9.62 parameters.
** libgnutls: Handle zero length plaintext for VIA PadLock functions.
This solves a potential crash on AES encryption for small size plaintext.
Patch by Matthias-Christian Ott.
** libgnutls: In DTLS don't combine multiple packets which exceed MTU.
Reported by Andreas Schultz. https://savannah.gnu.org/support/?108715
** libgnutls: In DTLS decode all handshake packets present in a record
packet, in a single pass. Reported by Andreas Schultz.
https://savannah.gnu.org/support/?108712
** libgnutls: When importing a CA file with a PKCS #11 URL, simply
import the certificates, if the URL specifies objects, rather than
treating it as trust module.
** libgnutls: When importing a PKCS #11 URL and we know the type of
object we are importing, don't require the object type in the URL.
** libgnutls: fixed openpgp authentication when gnutls_certificate_set_retrieve_function2
was used by the server.
** guile: Fix compilation on MinGW. Previously only the static version of the
'guile-gnutls-v-2' library would be built, preventing dynamic loading from Guile.
** guile: Fix harmless warning during compilation of gnutls.scm
Initially reported at <https://bugzilla.redhat.com/show_bug.cgi?id=1177847>.
** certtool: --pubkey-info will also attempt to load a public key
from stdin.
** gnutls-cli: Added --starttls-proto option. That allows to specify a
protocol for starttls negotiation.
** API and ABI modifications:
No changes since last version.
* Version 3.3.11 (released 2014-12-11)
** libgnutls: Corrected regression introduced in 3.3.9 related to
session renegotiation. Reported by Dan Winship.
** libgnutls: Corrected parsing issue with OCSP responses.
** API and ABI modifications:
No changes since last version.
* Version 3.3.10 (released 2014-11-10)
** libgnutls: Refuse to import v1 or v2 certificates that contain
extensions.
** libgnutls: Fixes in usage of PKCS #11 token callback
** libgnutls: Fixed bug in gnutls_x509_trust_list_get_issuer() when used
with a PKCS #11 trust module and without the GNUTLS_TL_GET_COPY flag.
Reported by David Woodhouse.
** libgnutls: Removed superfluous random generator refresh on every call
of gnutls_deinit(). That reduces load and usage of /dev/urandom.
** libgnutls: Corrected issue in export of ECC parameters to X9.63 format.
Reported by Sean Burford [GNUTLS-SA-2014-5].
** libgnutls: When gnutls_global_init() is called for a second time, it
will check whether the /dev/urandom fd kept is still open and matches
the original one. That behavior works around issues with servers that
close all file descriptors.
** libgnutls: Corrected behavior with PKCS #11 objects that are marked
as CKA_ALWAYS_AUTHENTICATE.
** certtool: The default cipher for PKCS #12 structures is 3des-pkcs12.
That option is more compatible than AES or RC4.
** API and ABI modifications:
No changes since last version.
* Version 3.3.9 (released 2014-10-13)
** libgnutls: Fixes in the transparent import of PKCS #11 certificates.
Reported by Joseph Peruski.
** libgnutls: Fixed issue with unexpected non-fatal errors resetting the
handshake's hash buffer, in applications using the heartbeat extension
or DTLS. Reported by Joeri de Ruiter.
** libgnutls: When both a trust module and additional CAs are present
account the latter as well; reported by David Woodhouse.
** libgnutls: added GNUTLS_TL_GET_COPY flag for
gnutls_x509_trust_list_get_issuer(). That allows the function to be used
in a thread safe way when PKCS #11 trust modules are in use.
** libgnutls: fix issue in DTLS retransmission when session tickets
were in use; reported by Manuel Pégourié-Gonnard.
** libgnutls-dane: Do not require the CA on a ca match to be direct CA.
** libgnutls: Prevent abort() in library if getrusage() fails. Try to
detect instead which of RUSAGE_THREAD and RUSAGE_SELF would work.
** guile: new 'set-session-server-name!' procedure; see the manual for
details.
** certtool: The authority key identifier will be set in a certificate only
if the CA's subject key identifier is set.
** API and ABI modifications:
No changes since last version.
* Version 3.3.8 (released 2014-09-18)
** libgnutls: Updates in the name constraints checks. No name constraints
will be checked for intermediate certificates. As our support for name
constraints is limited to e-mail addresses in DNS names, it is pointless
to check them on intermediate certificates.
** libgnutls: Fixed issues in PKCS #11 object listing. Previously multiple
object listing would fail completely if a single object could not be exported.
** libgnutls: Improved the performance of PKCS #11 object listing/retrieving,
by retrieving them in large batches. Report and suggestion by David
Woodhouse.
** libgnutls: Fixed issue with certificates being sanitized by gnutls prior
to signature verification. That resulted to certain non-DER compliant modifications
of valid certificates, being corrected by libtasn1's parser and restructured as
the original. Issue found and reported by Antti Karjalainen and Matti Kamunen from
Codenomicon.
** libgnutls: Fixes in gnutls_x509_crt_set_dn() and friends to properly handle
strings with embedded spaces and escaped commas.
** libgnutls: when comparing a CA certificate with the trusted list compare
the name and key only instead of the whole certificate. That is to handle
cases where a CA certificate was superceded by a different one with the same
name and the same key.
** libgnutls: when verifying a certificate against a p11-kit trusted
module, use the attached extensions in the module to override the CA's
extensions (that requires p11-kit 0.20.7).
** libgnutls: In DTLS prevent sending zero-size fragments in certain cases
of MTU split. Reported by Manuel Pégourié-Gonnard.
** libgnutls: Added gnutls_x509_trust_list_verify_crt2() which allows
verifying using a hostname and a purpose (extended key usage). That
enhances PKCS #11 trust module verification, as it can now check the purpose
when this function is used.
** libgnutls: Corrected gnutls_x509_crl_verify() which would always report
a CRL signature as invalid. Reported by Armin Burgmeier.
** libgnutls: added option --disable-padlock to allow disabling the padlock
CPU acceleration.
** p11tool: when listing tokens, list their type as well.
** p11tool: when listing objects from a trust module print any attached
extensions on certificates.
** API and ABI modifications:
gnutls_x509_crq_get_extension_by_oid2: Added
gnutls_x509_crt_get_extension_by_oid2: Added
gnutls_x509_trust_list_verify_crt2: Added
gnutls_x509_ext_print: Added
gnutls_x509_ext_deinit: Added
gnutls_x509_othername_to_virtual: Added
gnutls_pkcs11_obj_get_exts: Added
* Version 3.3.7 (released 2014-08-24)
** libgnutls: Added function to export the public key of a PKCS #11
private key. Contributed by Wolfgang Meyer zu Bergsten.
** libgnutls: Explicitly set the exponent in PKCS #11 key generation.
That improves compatibility with certain PKCS #11 modules. Contributed by
Wolfgang Meyer zu Bergsten.
** libgnutls: When generating a PKCS #11 private key allow setting
the WRAP/UNWRAP flags. Contributed by Wolfgang Meyer zu Bergsten.
** libgnutls: gnutls_pkcs11_privkey_t will always hold an open session
to the key.
** libgnutls: bundle replacements of inet_pton and inet_aton if not
available.
** libgnutls: initialize parameters variable on PKCS #8 decryption.
** libgnutls: gnutls_pkcs12_verify_mac() will not fail in other than SHA1
algorithms.
** libgnutls: gnutls_x509_crt_check_hostname() will follow the RFC6125
requirement of checking the Common Name (CN) part of DN only if there is
a single CN present in the certificate.
** libgnutls: The environment variable GNUTLS_FORCE_FIPS_MODE can be used
to force the FIPS mode, when set to 1.
** libgnutls: In DTLS ignore only errors that relate to unexpected packets
and decryption failures.
** p11tool: Added --info parameter.
** certtool: Added --mark-wrap parameter.
** danetool: --check will attempt to retrieve the server's certificate
chain and verify against it.
** danetool/gnutls-cli-debug: Added --app-proto parameters which can
be used to enforce starttls (currently only SMTP and IMAP) on the connection.
** danetool: Added openssl linking exception, to allow linking
with libunbound.
** API and ABI modifications:
GNUTLS_PKCS11_OBJ_ATTR_MATCH: Added
gnutls_pkcs11_privkey_export_pubkey: Added
gnutls_pkcs11_obj_flags_get_str: Added
gnutls_pkcs11_obj_get_flags: Added
* Version 3.3.6 (released 2014-07-23)
** libgnutls: Use inet_ntop to print IP addresses when available
** libgnutls: gnutls_x509_crt_check_hostname and friends will also check
IP addresses, and match documented behavior. Reported by David Woodhouse.
** libgnutls: DSA key generation in FIPS140-2 mode doesn't allow 1024
bit parameters.
** libgnutls: fixed issue in gnutls_pkcs11_reinit() which prevented tokens
being usable after a reinitialization.
** libgnutls: fixed PKCS #11 private key operations after a fork.
** libgnutls: fixed PKCS #11 ECDSA key generation.
** libgnutls: The GNUTLS_CPUID_OVERRIDE environment variable can be used to
explicitly enable/disable the use of certain CPU capabilities. Note that CPU
detection cannot be overriden, i.e., VIA options cannot be enabled on an Intel
CPU. The currently available options are:
0x1: Disable all run-time detected optimizations
0x2: Enable AES-NI
0x4: Enable SSSE3
0x8: Enable PCLMUL
0x100000: Enable VIA padlock
0x200000: Enable VIA PHE
0x400000: Enable VIA PHE SHA512
** libdane: added dane_query_to_raw_tlsa(); patch by Simon Arlott.
** p11tool: use GNUTLS_SO_PIN to read the security officer's PIN if set.
** p11tool: ask for label when one isn't provided.
** p11tool: added --batch parameter to disable any interactivity.
** p11tool: will not implicitly enable so-login for certain types of
objects. That avoids issues with tokens that require different login
types.
** certtool/p11tool: Added the --curve parameter which allows to explicitly
specify the curve to use.
** API and ABI modifications:
gnutls_certificate_set_x509_trust_dir: Added
gnutls_x509_trust_list_add_trust_dir: Added
* Version 3.3.5 (released 2014-06-26)
** libgnutls: Added gnutls_record_recv_packet() and gnutls_packet_deinit().
These functions provide a variant of gnutls_record_recv() that avoids
the final memcpy of data.
** libgnutls: gnutls_x509_crl_iter_crt_serial() was added as a
faster variant of gnutls_x509_crl_get_crt_serial() when coping with
very large structures.
** libgnutls: When the decoding of a printable DN element fails, then treat
it as unknown and print its hex value rather than failing. That works around
an issue in a TURKTRST root certificate which improperly encodes the
X520countryName element.
** libgnutls: gnutls_x509_trust_list_add_trust_file() will return the number
of certificates present in a PKCS #11 token when loading it.
** libgnutls: Allow the post client hello callback to put the handshake on
hold, by returning GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED.
** certtool: option --to-p12 will now consider --load-ca-certificate
** certtol: Added option to specify the PKCS #12 friendly name on command
line.
** p11tool: Allow marking a certificate copied to a token as a CA.
** API and ABI modifications:
GNUTLS_PKCS11_OBJ_FLAG_MARK_CA: Added
gnutls_x509_crl_iter_deinit: Added
gnutls_x509_crl_iter_crt_serial: Added
gnutls_record_recv_packet: Added
gnutls_packet_deinit: Added
gnutls_packet_get: Added
* Version 3.3.4 (released 2014-05-31)
** libgnutls: Updated Andy Polyakov's assembly code. That prevents a
crash on certain CPUs.
** API and ABI modifications:
No changes since last version.
* Version 3.3.3 (released 2014-05-30)
** libgnutls: Eliminated memory corruption issue in Server Hello parsing.
Issue reported by Joonas Kuorilehto of Codenomicon.
** libgnutls: gnutls_global_set_mutex() was modified to operate with the
new initialization process.
** libgnutls: Increased the maximum certificate size buffer
in the PKCS #11 subsystem.
** libgnutls: Check the return code of getpwuid_r() instead of relying
on the result value. That avoids issue in certain systems, when using
tofu authentication and the home path cannot be determined. Issue reported
by Viktor Dukhovni.
** libgnutls-dane: Improved dane_verify_session_crt(), which now attempts to
create a full chain. This addresses points from https://savannah.gnu.org/support/index.php?108552
** gnutls-cli: --dane will only check the end certificate if PKIX validation
has been disabled.
** gnutls-cli: --benchmark-soft-ciphers has been removed. That option cannot
be emulated with the implicit initialization of gnutls.
** certtool: Allow multiple organizations and organizational unit names to
be specified in a template.
** certtool: Warn when invalid configuration options are set to a template.
** ocsptool: Include path in ocsp request. This resolves#108582
(https://savannah.gnu.org/support/?108582), reported by Matt McCutchen.
** API and ABI modifications:
gnutls_credentials_get: Added
* Version 3.3.2 (released 2014-05-06)
** libgnutls: Added the 'very weak' certificate verification profile
that corresponds to 64-bit security level.
** libgnutls: Corrected file descriptor leak on random generator
initialization.
** libgnutls: Corrected file descriptor leak on PSK password file
reading. Issue identified using the Codenomicon TLS test suite.
** libgnutls: Avoid deinitialization if initialization has failed.
** libgnutls: null-terminate othername alternative names.
** libgnutls: gnutls_x509_trust_list_get_issuer() will operate correctly
on a PKCS #11 trust list.
** libgnutls: Several small bug fixes identified using valgrind and
the Codenomicon TLS test suite.
** libgnutls-dane: Accept a certificate using DANE if there is at least one
entry that matches the certificate. Patch by simon [at] arlott.org.
** libgnutls-guile: Fixed compilation issue.
** certtool: Allow exporting a CRL on DER format.
** certtool: The ECDSA keys generated by default use the SECP256R1 curve
which is supported more widely than the previously used SECP224R1.
** API and ABI modifications:
GNUTLS_PROFILE_VERY_WEAK: Added
* Version 3.3.1 (released 2014-04-19)
** libgnutls: Enforce more strict checks to heartbeat messages
concerning padding and payload. Suggested by Peter Dettman.
** libgnutls: Allow decoding PKCS #8 files with ECC parameters
from openssl.
** libgnutls: Several small bug fixes found by coverity.
** libgnutls: The conditionally available self-test functions
were moved to self-test.h.
** libgnutls: Fixed issue with the check of incoming data when two
different recv and send pointers have been specified. Reported and
investigated by JMRecio.
** libgnutls: Fixed issue in the RSA-PSK key exchange, which would
result to illegal memory access if a server hint was provided. Reported
by André Klitzing.
** libgnutls: Fixed client memory leak in the PSK key exchange, if a
server hint was provided.
** libgnutls: Corrected the *get_*_othername_oid() functions.
** API and ABI modifications:
No changes since last version.
* Version 3.3.0 (released 2014-04-10)
** libgnutls: The initialization of the library was moved to a
constructor. That is, gnutls_global_init() is no longer required
unless linking with a static library or a system that does not
support library constructors.
** libgnutls: static libraries are not built by default.
** libgnutls: PKCS #11 initialization is delayed to first usage.
That avoids long delays in gnutls initialization due to broken PKCS #11
modules.
** libgnutls: The PKCS #11 subsystem is re-initialized "automatically"
on the first PKCS #11 API call after a fork.
** libgnutls: certificate verification profiles were introduced
that can be specified as flags to verification functions. They
are enumerations in gnutls_certificate_verification_profiles_t
and can be converted to flags for use in a verification function
using GNUTLS_PROFILE_TO_VFLAGS().
** libgnutls: Added the ability to read system-specific initial
keywords, if they are prefixed with '@'. That allows a compile-time
specified configuration file to be used to read pre-configured priority
strings from. That can be used to impose system specific policies.
** libgnutls: Increased the default security level of priority
strings (NORMAL and PFS strings require at minimum a 1008 DH prime),
and set a verification profile by default. The LEGACY keyword is
introduced to set the old defaults.
** libgnutls: Added support for the name constraints PKIX extension.
Currently only DNS names and e-mails are supported (no URIs, IPs
or DNs).
** libgnutls: Security parameter SEC_PARAM_NORMAL was renamed to
SEC_PARAM_MEDIUM to avoid confusion with the priority string NORMAL.
** libgnutls: Added new API in x509-ext.h to handle X.509 extensions.
This API handles the X.509 extensions in isolation, allowing to parse
similarly formatted extensions stored in other structures.
** libgnutls: When generating DSA keys the macro GNUTLS_SUBGROUP_TO_BITS
can be used to specify a particular subgroup as the number of bits in
gnutls_privkey_generate; e.g., GNUTLS_SUBGROUP_TO_BITS(2048, 256).
** libgnutls: DH parameter generation is now delegated to nettle.
That unfortunately has the side-effect that DH parameters longer than
3072 bits, cannot be generated (not without a nettle update).
** libgnutls: Separated nonce RNG from the main RNG. The nonce
random number generator is based on salsa20/12.
** libgnutls: The buffer alignment provided to crypto backend is
enforced to be 16-byte aligned, when compiled with cryptodev
support. That allows certain cryptodev drivers to operate more
efficiently.
** libgnutls: Return error when a public/private key pair that doesn't
match is set into a credentials structure.
** libgnutls: Depend on p11-kit 0.20.0 or later.
** libgnutls: The new padding (%NEW_PADDING) experimental TLS extension has
been removed. It was not approved by IETF.
** libgnutls: The experimental xssl library is removed from the gnutls
distribution.
** libgnutls: Reduced the number of gnulib modules used in the main library.
** libgnutls: Added priority string %DISABLE_WILDCARDS.
** libgnutls: Added the more extensible verification function
gnutls_certificate_verify_peers(), that allows checking, in addition
to a peer's DNS hostname, for the key purpose of the end certificate
(via PKIX extended key usage).
** certtool: Timestamps for serial numbers were increased to 8 bytes,
and in batch mode to 12 (appended with 4 random bytes).
** certtool: When no CRL number is provided (or value set to -1), then
a time-based number will be used, similarly to the serial generation
number in certificates.
** certtool: Print the SHA256 fingerprint of a certificate in addition
to SHA1.
** libgnutls: Added --enable-fips140-mode configuration option (unsupported).
That option enables (when running on FIPS140-enabled system):
o RSA, DSA and DH key generation as in FIPS-186-4 (using provable primes)
o The DRBG-CTR-AES256 deterministic random generator from SP800-90A.
o Self-tests on initialization on ciphers/MACs, public key algorithms
and the random generator.
o HMAC-SHA256 verification of the library on load.
o MD5 is included for TLS purposes but cannot be used by the high level
hashing functions.
o All ciphers except AES are disabled.
o All MACs and hashes except GCM and SHA are disabled (e.g., HMAC-MD5).
o All keys (temporal and long term) are zeroized after use.
o Security levels are adjusted to the FIPS140-2 recommendations (rather
than ECRYPT).

Changes in 3.2.8.1:
Note, that I've realized that this release has issues with the
assembly files in win32 and macosx systems. In these systems
use gnutls 3.2.8.1.
3.2.8:
* Version 3.2.8 (released 2013-12-20)
** libgnutls: Updated code for AES-NI. That prevents an uninitialized
variable complaint from valgrind.
** libgnutls: Enforce a maximum size for DH primes.
** libgnutls: Added SSSE3 optimized SHA1, and SHA256, using Andy Polyakov's
code.
** libgnutls: Added SSSE3 optimized AES using Mike Hamburg's code.
** libgnutls: It only links to librt if the required functions are
not present in libc. This also prevents an indirect linking to libpthread.
** libgnutls: Fixed issue with gnulib strerror replacement by adding
the strerror gnulib module.
** libgnutls: The time provided in the TLS random values is only precise
on its first 3 bytes. That prevents leakage of the precise system
time (at least on the client side when only few connections are
done on a single server).
** certtool: The --verify option will use the system CAs if the
load-ca-certificate option is not provided.
** configure: Added option --with-default-blacklist-file to allow
specifying a certificate blacklist file.
** configure: Added --disable-non-suiteb-curves option. This option
restricts the supported curves to SuiteB curves.
** API and ABI modifications:
gnutls_record_check_corked: Added
* Version 3.2.7 (released 2013-11-23)
** libgnutls: gnutls_cipher_get_iv_size() now returns the correct IV size in
GCM ciphers (previously it returned the implicit IV used in TLS).
** libgnutls: gnutls_certificate_set_x509_key_file() et al when provided
with a PKCS #11 URL pointing to a certificate, will attempt to load the whole
chain.
** libgnutls: When traversing PKCS #11 tokens looking for an object, avoid
looking in unrelated to the object tokens.
** libgnutls: Added an experimental %DUMBFW option in priority strings. This
avoids a black hole behavior in some firewalls by sending a large client hello.
See http://www.ietf.org/mail-archive/web/tls/current/msg10423.html
** libgnutls: The GNUTLS_DEBUG_LEVEL variable if set to a log level number
will force output of debug messages to stderr.
** libgnutls: Fixed the setting of the ciphersuite when gnutls_premaster_set()
is used with another protocol than the GNUTLS_DTLS0_9 protocol.
** libgnutls: gnutls_x509_crt_set_expiration_time() will set the no well defined
expiration date when (time_t)-1 is specified as date.

will set to the no well defined expiration date (RFC5280), and no longer
chokes on integer overflows. Suggested by Stefan Buehler.
** certtool: Added new template options: 'activation_date', and
'expiration_date'.

GNUTLS_E_DECRYPTION_FAILED in all cases, and affect certtool operation
with encrypted keys. Reported by Yan Fiz.
** libgnutls: The minimum DH bits accepted by priorities NORMAL and
PERFORMANCE was set to previous defaults 727 bits. Reported by Diego
Elio Petteno.
** libgnutls: Corrected issue which prevented gnutls_pubkey_verify_hash()

it is now explicitly done on every session deinit.
** libgnutls: Simplified the DTLS sliding window implementation.
** libgnutls: The minimum DH bits accepted by a client are now set
by the specified priority string. The current values correspond to the
previous defaults (727 bits), except for the SECURE128 and SECURE192
strings which increase the minimum to 1248 and 1776 respectively.
** libgnutls: Added the gnutls_record_cork() and uncork API to enable
buffering in sending application data.

gnutls_record_can_use_length_hiding(). Contributed by Alfredo Pironti.
** libgnutls: Added the experimental %NEW_PADDING priority string. It enables
a new padding mechanism in TLS allowing arbitrary padding in TLS records
in all ciphersuites, which makes length-hiding more efficient and solves
the issues with timing attacks on CBC ciphersuites.

--load-privkey or --load-request to print the corresponding public keys.
** certtool: It is able to set certificate policies via a template.
** certtool: Added --hex-numbers option which prints big numbers in
an easier to parse format.
** p11tool: After key generation, outputs the public key (useful in
tokens that do not store the public key).
** danetool: It is being built even without libgnutls-dane (the
--check functionality is disabled though).

* Version 3.1.2 (released 2012-09-26)
** libgnutls: Fixed bug in gnutls_x509_trust_list_add_system_trust()
and gnutls_x509_trust_list_add_trust_mem() that prevented the loading
of certificates in the windows platform.
** libgnutls: Corrected bug in OpenPGP subpacket encoding.
** libgnutls: Added support for DTLS/TLS heartbeats by Olga Smolenchuk.
(the work was done during Google Summer of Code).
** libgnutls: Added X.509 certificate verification flag
GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
of unsorted certificate chains and is enabled by default for
TLS certificate verification (if gnutls_certificate_set_verify_flags()
does not override it).
** libgnutls: Prints warning on certificates that contain keys of
an insecure level. If the %COMPAT priority flag is not specified
the TLS connection fails.
** libgnutls: Correctly restore gnutls_record_recv() in DTLS mode
if interrupted during the retrasmition of handshake data.
** libgnutls: Better mingw32 support (patch by LRN).
** libgnutls: The %COMPAT keyword, if specified, will tolerate
key usage violation errors (they are far too common to ignore).
** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
which provides a tool to counter compression-related attacks where
parts of the data are controlled by the attacker _and_ are placed in
separate records (use with care - do not use compression if not sure).
** libgnutls: Depends on libtasn1 2.14 or later.
** certtool: Prints the number of bits of the public key algorithm
parameter in a private key.
** API and ABI modifications:
gnutls_x509_privkey_get_pk_algorithm2: Added
gnutls_heartbeat_ping: Added
gnutls_heartbeat_pong: Added
gnutls_heartbeat_allowed: Added
gnutls_heartbeat_enable: Added

gnutls_heartbeat_get_timeout: Added
GNUTLS_SEC_PARAM_WEAK: Added
GNUTLS_SEC_PARAM_INSECURE: Added
* Version 3.1.1 (released 2012-09-02)
** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.
** certtool: Changes in password handling of certtool.
Ask password when required and only if the '--password' option is not
given. If the '--password' option is given during key generation then
assume the PKCS #8 file format, instead of ignoring the password.
** tpmtool: No longer asks for key password in registered keys.
** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
wmNAF is now used for point multiplication and other optimizations.
(the major part of the work was done during Google Summer of Code).
** libgnutls: The default pull_timeout_function only uses select
instead of a combination of select() and recv() to prevent issues
when used in stream sockets in some systems.
** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
openssl.
** libgnutls: Fixed DSA and ECDSA signature generation in smart
cards. Thanks to Andreas Schwier from cardcontact.de for providing
me with ECDSA capable smart cards.
** API and ABI modifications:
gnutls_sign_algorithm_get: Added
gnutls_sign_get_hash_algorithm: Added
gnutls_sign_get_pk_algorithm: Added
* Version 3.1.0 (released 2012-08-15)
** libgnutls: Added direct support for TPM as a cryptographic module
in gnutls/tpm.h. TPM keys can be used in functions accepting files
using URLs of the following types:
tpmkey:file=/path/to/file
tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user
** libgnutls: Priority string level keywords can be combined.
For example the string "SECURE256:+SUITEB128" is now allowed.
** libgnutls: requires libnettle 2.5.
** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
for encryption and signatures.
** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
generic errors and signature verification errors in the verification
functions.
** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
to simplify parsing in most PKCS #12 use cases.
** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
the whole certificate chain (if any) to the credentials structure, instead
of only the end-user certificate.
** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
and gnutls_x509_privkey_import_pkcs8(), return consistently
GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
password was provided.
** libgnutls: Added gnutls_handshake_set_timeout() a function that
allows to set the maximum time spent in a handshake.
** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
by Alexandre Bique.
** tpmtool: Added. It is a tool to generate private keys in the
TPM.
** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
and --benchmark-tls-ciphers
** certtool: generated PKCS #12 structures may hold more than one
private key. Patch by Lucas Fisher.
** certtool: Added option --null-password to generate/decrypt keys
that use a NULL password (in schemas that distinguish between NULL
an empty passwords).
** minitasn1: Upgraded to libtasn1 version 2.13.
** API and ABI modifications:

* Version 2.12.9 (released 2011-08-21)
** libgnutls-extra: Replaced enumeration with unsigned
int, in openssl.h to make it identical to the 3.0.0 version.
This shouldn't introduce binary incompatibility.
** libgnutls: When asking for a PIN multiple times, the
flags in the callback were not being updated to reflect
for PIN low count or final try.

* Version 2.8.2 (released 2009-08-10)
** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
into 1) not printing the entire CN/SAN field value when printing a
certificate and 2) cause incorrect positive matches when matching a
hostname against a certificate. Some CAs apparently have poor
checking of CN/SAN values and issue these (arguable invalid)
certificates. Combined, this can be used by attackers to become a
MITM on server-authenticated TLS sessions. The problem is mitigated
since attackers needs to get one certificate per site they want to
attack, and the attacker reveals his tracks by applying for a
certificate at the CA. It does not apply to client authenticated TLS
sessions. Research presented independently by Dan Kaminsky and Moxie
Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
for providing one part of the patch. [GNUTLS-SA-2009-4].
** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
Before it always returned false. Reported by Peter Hendrickson
<pdh@wiredyne.com> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
** libgnutls: Fix off-by-one size computation error in unknown DN printing.
The error resulted in truncated strings when printing unknown OIDs in
X.509 certificate DNs. Reported by Tim Kosse
<tim.kosse@filezilla-project.org> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3651>.
** libgnutls: Return correct bit lengths of some MPIs.
gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
gnutls_dh_get_peers_public_bits. Before the reported value was
overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.
** libgnutls: Avoid internal error when invoked after GNUTLS_E_AGAIN.
Report and patch by Tim Kosse <tim.kosse@filezilla-project.org> in
<http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3671>
and
<http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3670>.
** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
Before we required that the runtime library used the same (or more
recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
that the runtime usage is above the minimum required. Reported by
Marco d'Itri <md@linux.it> via Andreas Metzler
<ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
** minitasn1: Internal copy updated to libtasn1 v2.3.
** tests: Fix failure in "chainverify" because a certificate have expired.
** API and ABI modifications:
No changes since last version.

*** API/ABI changes in GnuTLS 2.8 compared to GnuTLS 2.6.x
No offically supported interfaces have been modified or removed. The
library should be completely backwards compatible on both the source
and binary level.
The shared library no longer exports some symbols that have never been
officially supported, i.e., not mentioned in any of the header files.
The symbols are:
_gnutls*
gnutls_asn1_tab
Normally when symbols are removed, the shared library version has to
be incremented. This leads to a significant cost for everyone using
the library. Because none of the above symbols have ever been
intended for use by well-behaved applications, we decided that the it
would be better for those applications to pay the price rather than
incurring problems on the majority of applications.
If it turns out that applications have been using unofficial
interfaces, we will need to release a follow-on release on the v2.8
branch to exports additional interfaces. However, initial testing
suggests that few if any applications have been using any of the
internal symbols.
Although not a new change compared to 2.6.x, we'd like to remind you
interfaces have been modified so that X.509 chain verification now
also checks activation/expiration times on certificates. The affected
functions are:
gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
gnutls_certificate_verify_peers: Likewise.
gnutls_certificate_verify_peers2: Likewise.
GNUTLS_CERT_NOT_ACTIVATED: ADDED.
GNUTLS_CERT_EXPIRED: ADDED.
GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
This change in behaviour was made during the GnuTLS 2.6.x cycle, and
we gave our rationale for it in earlier release notes.
The following symbols have been added to the library:
gnutls_certificate_set_x509_simple_pkcs12_mem: ADDED
gnutls_x509_crl_get_authority_key_id: ADDED
gnutls_x509_crl_get_extension_data: ADDED
gnutls_x509_crl_get_extension_info: ADDED
gnutls_x509_crl_get_extension_oid: ADDED
gnutls_x509_crl_get_number: ADDED
gnutls_x509_crl_set_authority_key_id: ADDED
gnutls_x509_crl_set_number: ADDED
gnutls_x509_crq_get_attribute_data: ADDED
gnutls_x509_crq_get_attribute_info: ADDED
gnutls_x509_crq_get_basic_constraints: ADDED
gnutls_x509_crq_get_extension_by_oid: ADDED

gnutls_x509_crt_set_crq_extensions: ADDED
gnutls_x509_crt_verify_hash: ADDED
The following interfaces have been added to the header files:
GNUTLS_VERSION: ADDED, replaces LIBGNUTLS_VERSION.
GNUTLS_VERSION_MAJOR: ADDED, replaces LIBGNUTLS_VERSION_MAJOR.

* Version 2.7.8 (released 2009-05-03)
** libgnutls: Fix DSA key generation.
Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
** libgnutls: Check expiration/activation time on untrusted certificates.
Merged from stable branch. Reported by Romain Francoise
<romain@orebokech.com>. This changes the semantics of
gnutls_x509_crt_list_verify, which in turn is used by
gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
We add two new gnutls_certificate_status_t codes for reporting the new
error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
We also add a new gnutls_certificate_verify_flags flag,
GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
** lib: Linker version scripts reduces number of exported symbols.
The linker version script now lists all exported ABIs explicitly, to
avoid accidentally exporting unintended functions. Compared to
before, most symbols beginning with _gnutls* are no longer exported.
These functions have never been intended for use by applications, and
there were no prototypes for these function in the public header
files. Thus we believe it is possible to do this without incrementing
the library ABI version which normally has to be done when removing an
interface.
** lib: Limit exported symbols on systems without LD linker scripts.
Before all symbols were exported. Now we limit the exported symbols
to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
_gnutls*. This is a superset of the actual supported ABI, but still
an improvement compared to before. This is implemented using Libtool
-export-symbols-regex. It is more portable than linker version
scripts.
** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
This should have been done in the last release.
** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
Reported by Peter Hendrickson <pdh@wiredyne.com> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
** doc: Improved sections for the info manual.
We now follow the advice given by the texinfo manual on which
directory categories to use. In particular, libgnutls moved from the
'GNU Libraries' section to the 'Software libraries' and the command
line tools moved from 'Network Applications' to 'System
Administration'.
** API and ABI modifications:
gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
gnutls_certificate_verify_peers: Likewise.
gnutls_certificate_verify_peers2: Likewise.
GNUTLS_CERT_NOT_ACTIVATED: ADDED.
GNUTLS_CERT_EXPIRED: ADDED.
GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
* Version 2.7.7 (released 2009-04-20)
** libgnutls: Applied patch by Cedric Bail to add functions
gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
It is currently only used by the core library. This will enable a new
domain 'gnutls' for translations of the command line tools.
** Corrected possible memory corruption on signature verification failure.
Reported by Miroslav Kratochvil <exa.exa@gmail.com>
** API and ABI modifications:
gnutls_x509_crt_verify_hash: ADDED
gnutls_x509_crt_get_verify_algorithm: ADDED
* Version 2.7.6 (released 2009-02-27)
** certtool: Query for multiple dnsName subjectAltName in interactive mode.
This applies both to generating certificates and certificate requests.
** pkix.asn: Removed unneeded definitions to reduce memory usage.
** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
be used for chain verification.
** gnutls-serv: No longer disable MAC padding by default.
Use --priority NORMAL:%COMPAT to disable MAC padding again.
** gnutls-cli: Certificate information output format changed.
The tool now uses libgnutls' functions to print certificate
information. This avoids code duplication.
** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
** and %VERIFY_ALLOW_X509_V1_CA_CRT.
They can be used to override the default certificate chain validation
behaviour.
** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
specify the client hello message record version. Used to overcome buggy
TLS servers. Report by Martin von Gagern.
** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
** API and ABI modifications:
No changes since last version.
* Version 2.7.5 (released 2009-02-06)
** libgnutls: Accept chains where intermediary certs are trusted.
Before GnuTLS needed to validate the entire chain back to a
self-signed certificate. GnuTLS will now stop looking when it has
found an intermediary trusted certificate. The new behaviour is
useful when chains, for example, contains a top-level CA, an
intermediary CA signed using RSA-MD5, and an end-entity certificate.
To avoid chain validation errors due to the RSA-MD5 cert, you can
explicitly add the intermediary RSA-MD5 cert to your trusted certs.
The signature on trusted certificates are not checked, so the chain
has a chance to validate correctly. Reported by "Douglas E. Engert"
<deengert@anl.gov> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
** libgnutls: result_size in gnutls_hex_encode now holds
the size of the result. Report by John Brooks <special@dereferenced.net>.
** libgnutls: gnutls_handshake when sending client hello during a
rehandshake, will not offer a version number larger than the current.
Reported by Tristan Hill <stan@saticed.me.uk>.
** libgnutls: Permit V1 Certificate Authorities properly.
Before they were mistakenly rejected even though
GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
"Douglas E. Engert" <deengert@anl.gov> in

** API and ABI modifications:
No changes since last version.
* Version 2.7.4 (released 2009-01-07)
** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
This is a bugfix -- the previous attempt to do this from internal x509
certificate verification procedures did not return the correct value
for certificates using a weak hash. Reported by Daniel Kahn Gillmor
<dkg@fifthhorseman.net> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
Gillmor <dkg@fifthhorseman.net>.
** libgnutls: New interface to get key id for certificate requests.
Patch from David Marín Carreño <davefx@gmail.com> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
** libgnutls: gnutls_x509_crq_print will now also print public key id.
** certtool: --verify-chain now prints results of using library verification.
Earlier, certtool --verify-chain used its own validation algorithm
which wasn't guaranteed to give the same result as the libgnutls
internal validation algorithm. Now this command print a new final
line with header 'Chain verification output:' that contains the result
from using the internal verification algorithm on the same chain.
** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
** API and ABI modifications:
gnutls_x509_crq_get_key_id: ADDED.
* Version 2.7.3 (released 2008-12-10)
** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.

Andreas Metzler <ametzler@downhill.at.eu.org> in
<http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
** libgnutls: Libgcrypt initialization changed.
If libgcrypt has not already been initialized, GnuTLS will now
initialize libgcrypt with disabled secure memory. Initialize
libgcrypt explicitly in your application if you want to enable secure
memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
allocation functions, which doesn't use secure memory, so there is no
real change in behaviour.
** libgnutls: Fix memory leak in PSK authentication.
Reported by Michael Weiser <michael@weiser.dinsnail.net> in
<http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
** libgnutls: Small byte reads via gnutls_record_recv() optimized.
** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
It needs to be invoked before libgcrypt is initialized.
** gnutls-cli: Return non-zero exit code on error conditions.
** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
** tests: Added chainverify self-test that tests X.509 chain verifications.
** API and ABI modifications:
No changes since last version.
* Version 2.7.2 (released 2008-11-18)
** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
The flaw makes it possible for man in the middle attackers (i.e.,
active attackers) to assume any name and trick GNU TLS clients into
trusting that name. Thanks for report and analysis from Martin von
Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
Any updates with more details about this vulnerability will be added
to <http://www.gnu.org/software/gnutls/security.html>
** libgnutls: Fix namespace issue with version symbols.
The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
work but are deprecated.
** certtool: allow setting arbitrary key purpose object identifiers.
** libgnutls: Fix detection of C99 macros, to make debug logging work again.
** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
