Changes for tomcat:

• Update to Tomcat 9.0.121

• Catalina

• Fix: Ensure that a login-config conflict when merging web.xml fragments triggers a deployment failure. (markt)
• Code: Remove unnecessary calls to String.intern() in the parsing of configuration files. (markt)
• Fix: Extend sessionAttributeValueClassNameFilter to include filtering of dynamic proxy interface classes. (markt)
• Fix: Attempt to use rollback when persisting user data to the DataSourceUserDatabase fails and improve error reporting. (remm)
• Fix: 70143: Handle InvalidFileNameException when parsing parts to rethrow it as an IllegalStateException as mandated by the Servlet specification. (remm)
• Fix: Add missing reason to the JsonErrorReportValve. (remm)
• Fix: evaluation of the N and C flags for rewrite rules. (remm)
• Fix: qsd flag should always discard the original query string when rewriting. (remm)
• Fix: Add appropriate escaping for context path, current directory name and parent directory name for directory listings produced by the default servlet. Ensure XML escaping is used with XML output. (markt)
• Fix: When processing certificate subject names and issuer names within RewriteValve rules, always use the RFC 2253 format name. (markt)
• Fix: the incorrect rejection of requests using digest authentication when the client provided nonce count is at the upper boundary of the window (markt).
• Update: Separate the Context role mapping from the Servlet specification security-role-ref. (remm)
• Fix: Handle the case where the JNDIRealm is configured to perform role searches with userRoleAttribute but the attribute is not available or not configured for the current user. (markt)
• Fix: Improve handling of session attribute addition concurrent with session expiration. An application will now either see a successful addition followed by expiration or the addition will not succeed. It is no longer possible for the session to expire and the addition to succeed. This is of particular not for attributes that implement HttpSessionBindingListener. (markt)
• Fix: Add a new attribute to the Context, urlPatternsProvidedInDecodedForm. This attribute controls whether URLs and URL patterns provided in the deployment descriptor (web.xml), annotations and/or their programmatic equivalents are treated as being provided in URL-encoded form (i.e. using %nn encoding) or in decoded form. The Servlet specification requires that they are provided in decoded form. However, Tomcat has historically treated them as if they are provided in encoded form. In Tomcat 12, they will always be treated as if they are provided in decoded form. This setting enables migration from encoded form to decoded form on an application by application basis. This attribute will be removed in Tomcat 12 where it will effectively be hard-coded to true. (markt)
• Fix: Ensure the security constraint with the longest matching path is selected when more than one constraint matches the request path. (markt)
• Fix: If the request saved by FORM authentication uses a method other than GET, ensure that the security constraints are re-assessed after the saved request is restored and before it is processed. Custom Authenticator implementations that extend FormAuthenticator and override doAuthenticate() and/or restoreRequest() will require modification. (markt)
• Fix: Various improvements to the DataSourceRealm. A failure to connect to the database or an exception during either user or role lookup will now result in an authentication failure rather than a partially populated Principal. For CLIENT-CERT and SPNEGO authentication, the user must exist in the database for authentication to succeed. (markt)

• Coyote

• Update: Add utility AutoCloseable URLConnection wrapper, and use it to cleanup existing code patterns. (remm/markt)
• Fix: When processing an HTTP upgrade from HTTP/1.1 to HTTP/2, ensure that all the HTTP/1.1 data has been processed before switching protocols. (markt)
• Fix: Require every HTTP/2 request to provide an authority (either an :authority pseudo header or a Host header). (markt)
• Fix: Register the use of an HTTP/2 stream identifier earlier so that there is no possibility of a re-used stream identifier being accepted, regardless of how early in the HEADERS frame processing an error is detected. (markt)
• Add: new attributes (unixDomainSocketParentPermissions and unixDomainSocketParentOwner) to the NIO connector to provide additional control over the security of Unix Domain Sockets. Additional checks (enabled by default) have also been added for the directory where the Unix Domain Socket will be created.(markt)
• Fix: an allocation leak in the HTTP/2 backlog tracking when a stream is reset. (markt)

• Jasper

• Fix: Ensure internal state is reset before re-using ELParser. (markt)

• WebSocket

• Add: a limit (defaults to 8KB) on the size of the HTTP response headers accepted during a WebSocket HTTP upgrade. This is configured via the org.apache.tomcat.websocket.MAX_HTTP_RESPONSE_HEADER_BYTES user property. (markt)
• Fix: Improve URI template matching for WebSocket end points. Trailing slashes are now significant both for template definitions and URIs considered for potential matches to those URIs. Note that this means if a URI template ends in a variable without a trailing slash, that variable might be expanded to the empty string. (markt)
• Fix: Account for session ID changes when tracking WebSocket connections for closure because they were created under an authenticated HTTP session that has since ended. (markt)

• Web applications

• Fix: Documentation: Better sample httpd configuration for use with SSLValve and add a note that the exact configuration required will depend on the overall httpd configuration. (markt)
• Fix: Examples: Limit the buffering of messages in the WebSocket chat example to prevent a malicious client triggering excessive memory usage that could lead to a DoS. (markt)
• Fix: Documentation: Expand the description of the %S (session ID) access log pattern token. (markt)
• Fix: Manager: Use reflection to load clustering classes in sessionsList.jsp so the sessions list page renders correctly when clustering JARs are not present. (csutherl)

• Other

• Update: Maven Resolver Ant Tasks to 1.6.1. (rjung)
• Update: Objenesis to 3.6. (markt)
• Update: JSign to 7.5. (markt)
• Update: Bouncy Castle to 1.85. (markt)
• Add: Improvements to French translations. (remm)
• Add: Improvements to Japanese translations provided by tak7iji. (markt)

• Cluster

• Add: Change the default encryptionAlgorithm for the EncryptInterceptor to AES/GCM/NoPadding. This is a breaking change for the EncryptInterceptor. (markt)
• Add: Expand the documentation for the EncryptInterceptor to be more explicit regarding the security weaknesses of some supported algorithms. Also explicitly state that the replay protection is only effective for non-malleable algorithms. (markt)
• Add: Expand the Javadoc for the DNSMembershipProvider in particular explaining its behaviour and providing configuration advice if control more over cluster membership is required. (markt)

• jdbc-pool

• Fix: 70164: Correct the documentation for the testOnBorrow attribute. Pull request #1033 provided by Kohei Tamura. (markt)
