This update for apache2-mod_jk fixes the following issues: Update to version 1.2.49: Apache * Retrieve default request id from mod_unique_id. It can also be taken from an arbitrary environment variable by configuring "JkRequestIdIndicator". * Don"t delegate the generatation of the response body to httpd when the status code represents an error if the request used the HEAD method. * Only export the main module symbol. Visibility of module internal symbols led to crashes when conflicting with library symbols. Based on a patch provided by Josef ejka. * Remove support for implicit mapping of requests to workers. All mappings must now be explicit. IIS * Set default request id as a GUID. It can also be taken from an arbitrary request header by configuring "request_id_header". * Fix non-empty check for the Translate header. Common * Fix compiler warning when initializing and copying fixed length strings. * Add a request id to mod_jk log lines. * Enable configure to find the correct sizes for pid_t and pthread_t when building on MacOS. * Fix Clang 15/16 compatability. Pull request #6 provided by Sam James. * Improve XSS hardening in status worker. * Add additional bounds and error checking when reading AJP messages. Docs * Remove support for the Netscape / Sun ONE / Oracle iPlanet Web Server as the product has been retired. * Remove links to the old JK2 documentation. The JK2 documentation is still available, it is just no longer linked from the current JK documentation. * Restructure subsections in changelog starting with version 1.2.45. Changes for 1.2.47 and 1.2.48 updates: * Add: Apache: Extend trace level logging of method entry/exit to aid debugging of request mapping issues. * Fix: Apache: Fix a bug in the normalization checks that prevented file based requests, such as SSI file includes, from being processed. * Fix: Apache: When using JkAutoAlias, ensure that files that include spaces in their name are accessible. * Update: Common: Update the documentation to reflect that the source code for the Apache Tomcat Connectors has moved from Subversion to Git. * Fix: Common: When using set_session_cookie, ensure that an updated session cookie is issued if the load-balancer has to failover to a different worker. * Update: Common: Update config.guess and config.sub from https://git.savannah.gnu.org/git/config.git. * Update: Common: Update release script for migration to git. Update to version 1.2.46 Fixes: * Apache: Fix regression in 1.2.44 which resulted in socket_connect_timeout to be interpreted in units of seconds instead of milliseconds on platforms that provide poll. * Security: CVE-2018-11759 Connector path traversal [bsc#1114612] Update to version 1.2.45 Fixes: * Correct regression in 1.2.44 that broke request handling for OPTIONS * requests. * Improve path parameter parsing so that the session ID specified by the session_path worker property for load-balanced workers can be extracted from a path parameter in any segment of the URI, rather than only from the final segment. * Apache: Improve path parameter handling so that JkStripSession can remove session IDs that are specified on path parameters in any segment of the URI rather than only the final segment. * IIS: Improve path parameter handling so that strip_session can remove session IDs that are specified on path parameters in any segment of the URI rather than only the final segment. Updates: * Apache: Update the documentation to note additional limitations of the JkAutoAlias directive. Code: * Common: Optimize path parameter handling. Update to version 1.2.44 Updates: * Remove the Novell Netware make files and Netware specific source code since there has not been a supported version of Netware available for over five years. * Apache: Update the documentation to use httpd 2.4.x style access control directives. * Update PCRE bundled with the ISAPI redirector to 8.42. * Update config.guess and config.sub from https://git.savannah.gnu.org/git/config.git. Fixes: * Common: Use Local, rather than Global, mutexs on Windows to better support multi-user environments. * Apache: Use poll rather than select to avoid the limitations of select triggering an httpd crash. Patch provided by Koen Wilde. * ISAPI: Remove the check that rejects requests that contain path segments that match WEB-INF or META-INF as it duplicates a check that Tomcat performs and, because ISAPI does not have visibility of the current context path, it is impossible to implement this check without valid requests being rejected. * Refactor normalisation of request URIs to a common location and align the normalisation implementation for mod_jk with that implemented by Tomcat. Add: * Clarify the behvaiour of lb workers when all ajp13 workers fail with particular reference to the role of the retries attribute. * Add the new load-balancer worker property lb_retries to improve the control over the number of retries. Based on a patch provided by Frederik Nosi. * Add a note to the documentation that the CollapseSlashes options are now effectively hard-coded to CollpaseSlashesAll due to the changes made to align normalization with that implemented in Tomcat
