Catalina

Enable Tomcat to start if an (old) XML parser is configured that does not support allow-java-encodings. A warning will be logged if such an XML parser is detected. (markt)
Change the behaviour of custom error pages. If an error occurs after the response is committed, once the custom error page content has been added to the response the connection is now closed immediately rather than closed cleanly. i.e. the last chunk that marks the end of the response body is no longer sent. This acts as an additional signal to the client that the request experienced an error. (markt)
65479: When handling requests using JASPIC authentication, ensure that PasswordValidationCallback.getResult() returns the result of the password validation rather than always returning false. Fixed via pull request #438 provided by Robert Rodewald. (markt)

To avoid unnecessary cache revalidation, do not add an HTTP Expires header when setting adding an HTTP header of CacheControl: private. (markt)

Coyote

When writing an HTTP/2 response via sendfile (only enabled when useAsyncIO is true) the connection flow control window was sometimes ignored leading to various error conditions. sendfile now checks both the stream and connection flow control windows before writing. (markt)
Add debug logging for writing an HTTP/2 response via sendfile. (markt)
Correct bugs in the HTTP/2 connection flow control management that meant it was possible for a connection to stall waiting for a connection flow control window update that had already arrived. Any streams on that connection that were trying to write when this happened would time out. (markt)
65448: When using TLS with NIO, it was possible for a blocking response write to hang just before the final TLS packet associated with the response until the connection timed out at which point the final packet would be sent and the connection closed. (markt)
65454: Fix a race condition that could result in a delay to a new request. The new request could be queued to wait for an existing request to finish processing rather than the thread pool creating a new thread to process the new request. (markt)
65460: Correct a regression introduced in the previous release in the change to reduce the number of small HTTP/2 window updates sent for streams. A logic error meant that small window updates for the connection were dropped. This meant that the connection flow window slowly reduced over time until nothing could be sent. (markt)

Web applications

65404: Correct a regression in the fix for 63362 that caused the server status page in the Manager web application to be truncated if HTTP upgrade was used such as when starting a WebSocket connection. (markt)

Refactor JNDIRealm$JNDIConnection so its fields are accessible to sub-classes of JNDIRealm. (markt)
Fix serialization warnings in UserDatabasePrincipal reported by SpotBugs. (markt)
65397: Calls to ServletContext.getResourcePaths() no longer include symbolic links in the results unless allowLinking has been set to true. If a resource is skipped because of this change, a warning will be logged as this typically indicates a configuration issue. (markt)

Coyote

65368: Improve handling of clean closes of inbound TLS connections. Treat them the same way as clean closes of non-TLS connections rather than as unknown errors. (markt)
Modify the HTTP/2 connector not to sent small updates for stream flow control windows to the user agent as, depending on how the user agent is written, this may trigger small writes from the user agent that in turn trigger the overhead protection. Small updates for stream flow control windows are now combined with subsequent flow control window updates for that stream to ensure that all stream flow control window updates sent from Tomcat are larger than overheadWindowUpdateThreshold. (markt)
Add additional debug logging to track the current state of the HTTP/2 overhead count that Tomcat uses to detect and close potentially malicious connections. (markt)
Many HTTP/2 requests from browsers will trigger one overhead frame and one non-overhead frame. Change the overhead calculation so that a non-overhead frame reduces the current overhead count by 2 rather than 1. This means that, over time, the overhead count for a well-behaved connection will trend downwards. (markt)
Change the initial HTTP/2 overhead count from -10 to -10 * overheadCountFactor. This means that, regardless of the value chosen for overheadCountFactor, when a connection opens 10 overhead frames in a row will be required to trigger the overhead protection. (markt)
Increase the default overheadCountFactor from 1 to 10 and change the reduction in overhead count for a non-overhead frame from -2 to -20. This allows for a larger range (0-20) to be used for overheadCountFactor providing for finer-grained control. (markt)
Modify the parsing of HTTP header values that use the 1#token to ignore empty elements as per RFC 7230 section 7 instead of treating the presence of empty elements as an error. (markt)
Expand the unit tests for HttpServlet.doHead() and correct the flushing of the response buffer. The buffer used to behave as if it was one byte smaller than the configured size. The buffer was flushed (and the response committed if required) when the buffer was full. The buffer is now flushed (and the response committed if required) if the buffer is full and there is more data to write. (markt)
Fix an issue where concurrent HTTP/2 writes (or concurrent reads) to the same connection could hang and eventually timeout when async IO was enabled (it is enabled by default). (markt)

Update to the Eclipse JDT compiler 4.20. (markt)
Add support for specifying Java 17 (with the value 17) as the compiler source and/or compiler target for JSP compilation. If used with an Eclipse JDT compiler version that does not support these values, a warning will be logged and the latest supported version will used. (markt)
65377: Update the Java code generation for JSPs not to use the boxed primitive constructors as they have been deprecated in Java 9 and marked for future removal in Java 16. valueOf() is now used instead. (markt)

65272: Restore the optional HTTP feature that allows LF to be treated as a line terminator for the request line and/or HTTP headers lines as well as the standard CRLF. This behaviour was previously removed as a side-effect of the fix for CVE-2020-1935. (markt)

Let the RemoteCIDRValve inherit from RequestFilterValve and support all of its features. Especially add support for connector specific configuration using addConnectorPort. (rjung)
Add peerAddress to coyote request, which contains the IP address of the direct connection peer. If a reverse proxy sits in front of Tomcat and the protocol used is AJP or HTTP in combination with the RemoteIp(Valve|Filter), the peer address might differ from the remoteAddress. The latter then contains the address of the client in front of the reverse proxy, not the address of the proxy itself. Support for the peer address has been added to the RemoteAddrValve and RemoteCIDRValve with the new attribute usePeerAddress. This can be used to restrict access to Tomcat based on the reverse proxy IP address, which is especially useful to harden access to AJP connectors. The peer address can also be logged in the access log using the new %{peer}a syntax. (rjung)
