* *) mod_http2: v2.0.15 with the following fixes and improvementsStefan Eissing2023-05-121-0/+62
| | | | | | | | | | | | | | | | | | | | | | | - New directive 'H2EarlyHint name value' to add headers to a response, picked up already when a "103 Early Hints" response is sent. 'name' and 'value' must comply to the HTTP field restrictions. This directive can be repeated several times and header fields of the same names add. Sending a 'Link' header with 'preload' relation will also cause a HTTP/2 PUSH if enabled and supported by the client. - Fixed an issue where requests were not logged and accounted in a timely fashion when the connection returns to "keepalive" handling, e.g. when the request served was the last outstanding one. This led to late appearance in access logs with wrong duration times reported. - Accurately report the bytes sent for a request in the '%O' Log format. This addresses #203, a long outstanding issue where mod_h2 has reported numbers over-eagerly from internal buffering and not what has actually been placed on the connection. The numbers are now the same with and without H2CopyFiles enabled. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1909769 13f79535-47bb-0310-9956-ffa450edef68
* *) mod_http2: new directive 'H2MaxDataFrameLen n' to limit the maximumStefan Eissing2023-02-161-0/+22
| | | | | | | | | | | | | amount of response body bytes put into a single HTTP/2 DATA frame. Setting this to 0 places no limit (but the max size allowed by the protocol is observed). The module, by default, tries to use the maximum size possible, which is somewhat around 16KB. This sets the maximum. When less response data is available, smaller frames will be sent. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1907697 13f79535-47bb-0310-9956-ffa450edef68
* *) mod_http2: field values (headers and trailers) are stripped ofStefan Eissing2022-10-221-29/+0
| | | | | | | | | | | | | leading/trailing whitespace (space +htab) before being processed or send in a response. This is compatible behaviour to HTTP/1.1 parsers that strip incoming headers of such characters. [Stefan Eissing] - removed intermittent "H2HeaderStrictness" directive again. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1904777 13f79535-47bb-0310-9956-ffa450edef68
* Sync with v2.0.10 from github:Stefan Eissing2022-10-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Extensive testing in production done by Alessandro Bianchi (@alexskynet) on the v2.0.x versions for stability. Many thanks! * refactored stream response handling to reflect the different phases (response/data/trailers) more clearly and help resolving cpu busy loops. * Adding more negative tests for handling of errored responses to cover edge cases. * mod_http2: fixed handling of response where neiter an EOS nor an ERROR was received as a cause to reset the stream. * mod_proxy_http2: generating error buckets for fault response bodies, to signal failure to fron when response header were already sent. v2.0.9 -------------------------------------------------------------------------------- * Fixed a bug where errors during reponse body handling did not lead to a proper RST_STREAM. Instead processing went into an infinite loop. Extended test cases to catch this condition. v2.0.8 -------------------------------------------------------------------------------- * Delaying input setup of a stream just before processing starts. This allows any EOS indicator arriving from the client before that to take effect. Without knowing that a stream has no input, internal processing has to simulate chunked encoding. This is not wrong, but somewhat more expensive and mod_security has been reported to be allergic to seeing 'chunked' on some requests. See <https://bz.apache.org/bugzilla/show_bug.cgi?id=66282>. * mod_proxy_http2: fixed #235 by no longer forwarding 'Host:' header when request ':authority' is known. Improved test case that did not catch that the previous 'fix' was incorrect. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1904522 13f79535-47bb-0310-9956-ffa450edef68
* *) mod_http2: new directive "H2HeaderStrictness" to control the complianceStefan Eissing2022-09-261-0/+29
| | | | | | | | | | | | | | | | level of header checks as defined in the HTTP/2 RFCs. Default is 7540. 9113 activates the checks for forbidden leading/trailing whitespace in field values (available from nghttp2 v1.50.0 on). - source sync with github version - fix for keepalive idle wait in mpm_worker setup - ensuring EOS when secondary connection has been handled - fixed race in late input EOS arrival when stream was already scheduled for execution. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1904269 13f79535-47bb-0310-9956-ffa450edef68
* *) mod_http2: new implementation of h2 worker pool.Stefan Eissing2022-06-171-34/+30
| | | | | | | | | | | | | - O(1) cost at registration of connection processing producers - no limit on registered producers - join of ongoing work on unregister - callbacks to unlink dependencies into other h2 code - memory cleanup on workers deactivation (on idle timeouts) - idle_limit as apr_time_t instead of seconds git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1902005 13f79535-47bb-0310-9956-ffa450edef68
* *) mod_http2:Stefan Eissing2021-10-121-130/+68
| | | | | | | | | | | | | | | | | | | | | | - Fixed an issue since 1.15.24 that "Server" headers in proxied requests were overwritten instead of preserved. [PR by @daum3ns] - Added directove 'H2StreamTimeout' to configure a separate value for HTTP/2 streams, overriding server's 'Timeout' configuration. [rpluem] - HTTP/2 connections now use pollsets to monitor the status of the ongoing streams and their main connection when host OS allows this. - Removed work-arounds for older versions of libnghttp2 and checking during configure that at least version 1.15.0 is present. - The HTTP/2 connection state handler, based on an experiment and draft at the IETF http working group (abandoned for some time), has been removed. - H2SerializeHeaders no longer has an effect. A warning is logged when it is set to "on". The switch enabled the internal writing of requests to be parsed by the internal HTTP/1.1 protocol handler and was introduced to avoid potential incompatibilities during the introduction of HTTP/2. - Removed the abort/redo of tasks when mood swings lower the active limit. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1894163 13f79535-47bb-0310-9956-ffa450edef68

Found and reported by <Armin.Abfalterer@united-security-providers.ch> and <Marcial.Rion@united-security-providers.ch>. [Stefan Eissing] *) mod_http2: Multiple field length violations in the same request no longer cause several log entries to be written. [@mkauf] git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1870454 13f79535-47bb-0310-9956-ffa450edef68
* *) mod_http2: new configuration directive: ```H2Padding numbits``` to control Stefan Eissing2019-03-071-0/+36
| | | | | | | | | | | | | | | | | | | | padding of HTTP/2 payload frames. 'numbits' is a number from 0-8, controlling the range of padding bytes added to a frame. The actual number added is chosen randomly per frame. This applies to HEADERS, DATA and PUSH_PROMISE frames equally. The default continues to be 0, e.g. no padding. [Stefan Eissing] *) mod_http2: ripping out all the h2_req_engine internal features now that mod_proxy_http2 has no more need for it. Optional functions are still declared but no longer implemented. While previous mod_proxy_http2 will work with this, it is recommeneded to run the matching versions of both modules. [Stefan Eissing] *) mod_proxy_http2: changed mod_proxy_http2 implementation and fixed several bugs which resolve PR63170. The proxy module does now a single h2 request on the (reused) connection and returns. [Stefan Eissing] git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1854963 13f79535-47bb-0310-9956-ffa450edef68

[Stefan Eissing] *) mod_http2: HEAD requests to some module such as mod_cgid caused the stream to terminate improperly and cause a HTTP/2 PROTOCOL_ERROR.
