JDK-8244460: Support for certificate_authorities Extension
dd41aa
==========================================================
dd41aa
The "certificate_authorities" extension is an optional extension
dd41aa
introduced in TLS 1.3. It is used to indicate the certificate
dd41aa
authorities (CAs) that an endpoint supports and should be used by the
dd41aa
receiving endpoint to guide certificate selection.
dd41aa
dd41aa
With this JDK release, the "certificate_authorities" extension is
dd41aa
supported for TLS 1.3 in both the client and the server sides.  This
dd41aa
extension is always present for client certificate selection, while it
dd41aa
is optional for server certificate selection.
dd41aa
dd41aa
Applications can enable this extension for server certificate
dd41aa
selection by setting the `jdk.tls.client.enableCAExtension` system
dd41aa
property to `true`.  The default value of the property is `false`.
dd41aa
dd41aa
Note that if the client trusts more CAs than the size limit of the
dd41aa
extension (less than 2^16 bytes), the extension is not enabled.  Also,
dd41aa
some server implementations do not allow handshake messages to exceed
dd41aa
2^14 bytes.  Consequently, there may be interoperability issues when
dd41aa
`jdk.tls.client.enableCAExtension` is set to `true` and the client
dd41aa
trusts more CAs than the server implementation limit.

JDK-8260597: Added 2 HARICA Root CA Certificates
935881

JDK-8236730: Weak Named Curves in TLS, CertPath, and Signed JAR Disabled by Default
59ff46
===================================================================================
59ff46
Weak named curves are disabled by default by adding them to the
59ff46
following `disabledAlgorithms` security properties:
59ff46
59ff46
* jdk.tls.disabledAlgorithms
59ff46
* jdk.certpath.disabledAlgorithms
59ff46
* jdk.jar.disabledAlgorithms
59ff46
59ff46
Red Hat has always disabled many of the curves provided by upstream,
59ff46
so the only addition in this release is:
59ff46
59ff46
* secp256k1
59ff46
59ff46
The curves that remain enabled are:
59ff46
59ff46
* secp256r1
59ff46
* secp384r1
59ff46
* secp521r1
59ff46
* X25519
59ff46
* X448
59ff46
59ff46
When large numbers of weak named curves need to be disabled, adding
59ff46
individual named curves to each `disabledAlgorithms` property would be
59ff46
overwhelming. To relieve this, a new security property,
59ff46
`jdk.disabled.namedCurves`, is implemented that can list the named
59ff46
curves common to all of the `disabledAlgorithms` properties. To use
59ff46
the new property in the `disabledAlgorithms` properties, precede the
59ff46
full property name with the keyword `include`.  Users can still add
59ff46
individual named curves to `disabledAlgorithms` properties separate
59ff46
from this new property.  No other properties can be included in the
59ff46
`disabledAlgorithms` properties.
59ff46
59ff46
To restore the named curves, remove the `include
59ff46
jdk.disabled.namedCurves` either from specific or from all
59ff46
`disabledAlgorithms` security properties. To restore one or more
59ff46
curves, remove the specific named curve(s) from the
59ff46
`jdk.disabled.namedCurves` property.

JDK-8244286: Tools Warn If Weak Algorithms Are Used
609ec2
===================================================
609ec2
The `keytool` and `jarsigner` tools have been updated to warn users
609ec2
when weak cryptographic algorithms are used in keys, certificates, and
609ec2
signed JARs before they are disabled. The weak algorithms are set in
609ec2
the `jdk.security.legacyAlgorithms` security property in the
609ec2
`java.security` configuration file. In this release, the tools issue
609ec2
warnings for the SHA-1 hash algorithm and 1024-bit RSA/DSA keys.

JDK-8256490: Disable TLS 1.0 and 1.1
59ff46
====================================
59ff46
TLS 1.0 and 1.1 are versions of the TLS protocol that are no longer
59ff46
considered secure and have been superseded by more secure and modern
59ff46
versions (TLS 1.2 and 1.3).
59ff46
59ff46
These versions have now been disabled by default. If you encounter
59ff46
issues, you can, at your own risk, re-enable the versions by removing
59ff46
"TLSv1" and/or "TLSv1.1" from the `jdk.tls.disabledAlgorithms`
59ff46
security property in the `java.security` configuration file.
59ff46
59ff46
JDK-8242147: New System Properties to Configure the TLS Signature Schemes
59ff46
=========================================================================
59ff46
Two new system properties have been added to customize the TLS
59ff46
signature schemes in JDK. `jdk.tls.client.SignatureSchemes` has been
59ff46
added for the TLS client side, and `jdk.tls.server.SignatureSchemes`
59ff46
has been added for the server side.
59ff46
59ff46
Each system property contains a comma-separated list of supported
59ff46
signature scheme names specifying the signature schemes that could be
59ff46
used for the TLS connections.
59ff46
59ff46
The names are described in the "Signature Schemes" section of the
59ff46
*Java Security Standard Algorithm Names Specification*.

935881
JDK-8177368: Several incorporation steps are silently failing when an error should be reported
935881
==============================================================================================
935881
Reporting previously silent errors found during incorporation, JLS
935881
8§18.3, was supposed to be a clean-up with performance only
935881
implications. But consider the test case:
935881
935881
import java.util.Arrays;
935881
import java.util.List;
935881
935881
class Klass {
935881
  public static  List<List<A>> foo(List... lists) {
935881
    return foo(Arrays.asList(lists));
935881
    }
935881
935881
  public static  List<List<B>> foo(List> lists) {
935881
    return null;
935881
  }
935881
}
935881
935881
This code was not accepted before the patch for [1], but after this
935881
patch the compiler is accepting it. Accepting this code is the right
935881
behavior as not reporting incorporation errors was a bug in the
935881
compiler.  While determining the applicability of method: 
935881
List<List<B>> foo(List> lists) for which
935881
we have the constraints: b <: Object t <: List t<:Object
935881
List <: t first, inference variable b is selected for
935881
instantiation: b = CAP1 of ? extends A so this implies that: t <:
935881
List t<: Object List <: t
935881
935881
Now all the bounds are checked for consistency. While checking if
935881
List is a subtype of List
935881
a bound error is reported. Before the compiler was just swallowing
935881
it. As now the error is reported while inference variable b is being
935881
instantiated, the bound set is rolled back to it's initial state, 'b'
935881
is instantiated to Object, and with this instantiation the constraint
935881
set is solvable, the method is applicable, it's the only applicable
935881
one and the code is accepted as correct. The compiler behavior in this
935881
case is defined at JLS 8 §18.4
935881
935881
This fix has source compatibility impact, right now code that wasn't
935881
being accepted is now being accepted by the javac compiler. Currently
935881
there are no reports of any other kind of incompatibility.

JDK-8221441: SunPKCS11 Provider Upgraded with Support for PKCS#11 v2.40
56ca5d
=======================================================================
56ca5d
The SunPKCS11 provider has been updated with support for PKCS#11
56ca5d
v2.40. This version adds support for more algorithms such as the
56ca5d
AES/GCM/NoPadding cipher, DSA signatures using SHA-2 family of message
56ca5d
digests, and RSASSA-PSS signatures when the corresponding PKCS11
56ca5d
mechanisms are supported by the underlying PKCS11 library.

JDK-8242059: Support for canonicalize in krb5.conf
56ca5d
==================================================
56ca5d
The 'canonicalize' flag in the [krb5.conf file][0] is now supported by
56ca5d
the JDK Kerberos implementation. When set to *true*, RFC 6806 [1] name
56ca5d
canonicalization is requested by clients in TGT requests to KDC
56ca5d
services (AS protocol). Otherwise, and by default, it is not
56ca5d
requested.
56ca5d
56ca5d
The new default behavior is different from previous releases where
56ca5d
name canonicalization was always requested by clients in TGT requests
56ca5d
to KDC services (provided that support for RFC 6806[1] was not
56ca5d
explicitly disabled with the *sun.security.krb5.disableReferrals*
56ca5d
system or security properties).

JDK-8202891: Updated xmldsig Implementation to Apache Santuario 2.1.1
56ca5d
=====================================================================
56ca5d
The XMLDSig provider implementation in the `java.xml.crypto` module has been updated to version 2.1.1 of Apache Santuario.
56ca5d
56ca5d
New features include:
56ca5d
56ca5d
1. Support for the SHA-224 and SHA-3 DigestMethod algorithms specified
56ca5d
in RFC 6931.
56ca5d
2. Support for the HMAC-SHA224, RSA-SHA224, ECDSA-SHA224, and
56ca5d
RSASSA-PSS family of SignatureMethod algorithms specified in RFC 6931.

JDK-8238185: New OpenJDK-specific JDK 8 Updates System Property to fallback to legacy Base64 Encoding format
56ca5d
============================================================================================================
56ca5d
The upgrade to the Apache Santuario libraries (see above) introduced
56ca5d
an issue where XML signature using Base64 encoding resulted in
56ca5d
appending `&#xd` or `&#13` to the encoded output. This behavioural
56ca5d
change was made in the Apache Santuario codebase to comply with RFC
56ca5d
2045. The Santuario team has adopted a position of keeping their
56ca5d
libraries compliant with RFC 2045.
56ca5d
56ca5d
Earlier versions of OpenJDK 8 using the legacy encoder returns encoded
56ca5d
data in a format without `&#xd` or `&#13`.
56ca5d
56ca5d
Therefore a new system property, specific to the 8 update stream,
56ca5d
`com.sun.org.apache.xml.internal.security.lineFeedOnly` is made
56ca5d
available to fall back to the legacy Base64 encoded format.
56ca5d
56ca5d
Users can set this flag in one of two ways:
56ca5d
56ca5d
1. -Dcom.sun.org.apache.xml.internal.security.lineFeedOnly=true
56ca5d
56ca5d
2. System.setProperty("com.sun.org.apache.xml.internal.security.lineFeedOnly", "true")
56ca5d
56ca5d
This new system property is disabled by default. It has no effect on
56ca5d
default behaviour nor when
56ca5d
`com.sun.org.apache.xml.internal.security.ignoreLineBreaks` property
56ca5d
is set.
56ca5d
56ca5d
Later JDK family versions will only support the recommended property:
56ca5d
56ca5d
`com.sun.org.apache.xml.internal.security.ignoreLineBreaks`
56ca5d
56ca5d
JDK-8254177: US/Pacific-New Zone name removed as part of tzdata2020b
56ca5d
====================================================================
56ca5d
Following JDK's update to tzdata2020b, the long-obsolete files
56ca5d
pacificnew and systemv have been removed. As a result, the
56ca5d
"US/Pacific-New" zone name declared in the pacificnew data file is no
56ca5d
longer available for use.
56ca5d
56ca5d

JDK-8240687: JDK Flight Recorder Integrated to OpenJDK 8u
8df9ce
=========================================================
8df9ce
8df9ce
OpenJDK 8u now contains the backport of JEP 328: Flight Recorder
8df9ce
(https://openjdk.java.net/jeps/328) from later versions of OpenJDK.
8df9ce
8df9ce
JFR is a low-overhead framework to collect and provide data helpful to
8df9ce
troubleshoot the performance of the OpenJDK runtime and of Java
8df9ce
applications. It consists of a new API to define custom events under
8df9ce
the jdk.jfr namespace and a JMX interface to interact with the
8df9ce
framework. The recording can also be initiated with the application
8df9ce
startup using the -XX:+FlightRecorder flag or via jcmd. JFR replaces
8df9ce
the +XX:EnableTracing feature introduced in JEP 167, providing a more
8df9ce
efficient way to retrieve the same information. For compatibility
8df9ce
reasons, +XX:EnableTracing is still accepted, however no data will be
8df9ce
printed.
8df9ce
8df9ce
While JFR is not built by default upstream, it is included in Red Hat
8df9ce
binaries for supported architectures (x86_64, AArch64 & PowerPC 64)

JDK-8240191: Allow SunPKCS11 initialization with NSS when external FIPS modules are present in the Security Modules Database
8df9ce
============================================================================================================================
8df9ce
8df9ce
The SunPKCS11 security provider can now be initialized with NSS when
8df9ce
FIPS-enabled external modules are configured in the Security Modules
8df9ce
Database (NSSDB). Prior to this change, the SunPKCS11 provider would
8df9ce
throw a RuntimeException with the message: "FIPS flag set for
8df9ce
non-internal module" when such a library was configured for NSS in
8df9ce
non-FIPS mode.
8df9ce
8df9ce
This change allows the JDK to work properly with recent NSS releases
8df9ce
on GNU/Linux operating systems when the system-wide FIPS policy is
8df9ce
turned on.
8df9ce
8df9ce

84a771
84a771
The SunRsaSign and SunJCE providers have been enhanced with support
84a771
for more algorithms defined in PKCS#1 v2.2, such as RSASSA-PSS
84a771
signature and OAEP using FIPS 180-4 digest algorithms. New
84a771
constructors and methods have been added to relevant JCA/JCE classes
84a771
under the `java.security.spec` and `javax.crypto.spec` packages for
84a771
supporting additional RSASSA-PSS parameters.

JDK-8227564: Allow SASL Mechanisms to Be Restricted
84a771
===================================================
84a771
84a771
A security property named `jdk.sasl.disabledMechanisms` has been added
84a771
that can be used to disable SASL mechanisms. Any disabled mechanism
84a771
will be ignored if it is specified in the `mechanisms` argument of
84a771
`Sasl.createSaslClient` or the `mechanism` argument of
84a771
`Sasl.createSaslServer`. The default value for this security property
84a771
is empty, which means that no mechanisms are disabled out-of-the-box.
