OVE-20201118-0001. + Sponsored by: Robert Klemme + - Fixed a memory leak in the show-status CGI handler when + no action files are configured. Commit c62254a686. + OVE-20201118-0002. + Sponsored by: Robert Klemme + - Fixed a memory leak in the show-status CGI handler when + no filter files are configured. Commit 1b1370f7a8a. + OVE-20201118-0003. + Sponsored by: Robert Klemme + - Fixes a memory leak when client tags are active. + Commit 245e1cf32. OVE-20201118-0004. + Sponsored by: Robert Klemme + - Fixed a memory leak if multiple filters are executed + and the last one is skipped due to a pcre error. + Commit 5cfb7bc8fe. OVE-20201118-0005. + - Prevent an unlikely dereference of a NULL-pointer that + could result in a crash if accept-intercepted-requests + was enabled, Privoxy failed to get the request destination + from the Host header and a memory allocation failed. + Commit 7530132349. CID 267165. OVE-20201118-0006. + - Fixed memory leaks in the client-tags CGI handler when + client tags are configured and memory allocations fail. + Commit cf5640eb2a. CID 267168. OVE-20201118-0007. + - Fixed memory leaks in the show-status CGI handler when memory + allocations fail. Commit 064eac5fd0 and commit fdee85c0bf3. + CID 305233. OVE-20201118-0008. + +- General improvements: + - Added experimental https inspection support which allows to filter + https traffic. To enable it, install MbedTLS and configure with + --with-mbedtls, or install OpenSSL or LibreSSL and configure + with --with-openssl. + Afterwards configure the directives in section 7 of the + config file and enable the +https-inspection action. + Initial MbedTLS-based code contributed by Vaclav Svec, + initial OpenSSL support contributed by Maxim Antonov. + With help from Nedzad Hrnjica and Ho+ Ho+ Ho+. + Integration and improvements sponsored by Robert Klemme. + - pcrs: Request JIT compilation if it's supported and + the filter isn't dynamic. This can speed up filtering. + - Added support for Brotli decompression. + Sponsored by: Robert Klemme + - Added FEATURE_EXTENDED_STATISTICS to gather statistics for + block reasons and filter executions. To enable it, configure + with --enable-extended-statistics and visit + http://config.privoxy.org/show-status. + Sponsored by: Robert Klemme + - Use the IP_FREEBIND socket option, if defined. This allows + Privoxy to bind to not-yet assigned IP addresses which is + useful in failover environments. + Patch by Sam Varshavchik. + - Allow to use extended host patterns and vanilla host patterns + at the same time by prefixing extended host patterns with + "PCRE-HOST-PATTERN:". To enable this, configure with + --enable-pcre-host-patterns. + Sponsored by: Robert Klemme + - Added "Cross-origin resource sharing" (CORS) support. + This allows to access Privoxy's CGI interface via JavaScript from + another domain (white-listed with the new cors-allowed-origin directive). + Based on a patch by Nedzad Hrnjica. + Sponsored by: Robert Klemme. + - Add SOCKS5 username/password support. + Based on a patch by Sam, improved by Ivan Romanov. + Closes Patch#141 and solves TODO#105. + - Bump the maximum number of action and filter files + to 100 each. + Sponsored by: Robert Klemme + - Fixed handling of filters with "split-large-forms 1" + when using the CGI editor. + Reported by withoutname in #921. + - Better detect a mismatch of connection details when + figuring out whether or not a connection can be reused. + - Don't send a "Connection failure" message instead of the + "DNS failure" message. + Sponsored by: Robert Klemme + - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted + requests were only logged with LOG_LEVEL_REQUEST when they weren't + crunched (in which case they were logged with LOG_LEVEL_CRUNCH). + This was documented behaviour, but logging all requests seems more useful. + - Fixed locking around localtime() and gmtime(). + - Removed OS/2 support. We haven't provided OS/2 packages in years, + it complicated the code and it depended on a fallback snprintf() + implementation which is GPLv2 only. + - Remove the fallback snprintf() implementation + Now that OS/2 support is gone we no longer need it. + - Fixed a bunch of format specifiers log messages. + - Added a missing apostrophe in the 'More Privoxy' menu. + - Explicitly prevent use of FEATURE_CONNECTION_SHARING + without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense + and does not compile anyway. + Sponsored by: Robert Klemme + - Fix build without FEATURE_CONNECTION_KEEP_ALIVE. + Sponsored by: Robert Klemme + - Downgrade the 'Graceful termination requested' message + to LOG_LEVEL_INFO as it isn't an error. + Sponsored by: Robert Klemme + - decompress_iob(): Downgrade the no-content message to LOG_LEVEL_RE_FILTER + While at it, fix a typo in a comment. + Sponsored by: Robert Klemme + - Fixed a couple of cppcheck warnings. + - Rename LOG_LEVEL_GPC to LOG_LEVEL_REQUEST. + Only the shadow knows what "GPC" is supposed to stand for. + - Remove SourceForge references in copyright headers. + - Upgrade a bunch of links to the homepage to https://. + - Add 'no-brotli-accepted' filter which prevents the + use of Brotli compression. + - Changed license for pcrs to GPLv2+ after getting the + permission from Andreas. This allows to redistribute + Privoxy under the GPLv3 which is required when linking + to future mbedTLS versions which are expected to be + licensed under the Apache 2.0 license only. + - Updated a bunch of tests that have to expect status code 403 + now after r1.168/070e904afa5. + - Lowercase the host name in the request line. + - Only set SOURCE_DATE_EPOCH if it's not already set so + distributions can overwrite it through the environment. + +- Documentation changes: + - Explain that Privoxy has to be distributed under the + GPLv3 (or later) when linked with an MbedTLS version + that is licensed under the Apache 2.0 license. + - Import the GNU GPLv3 and include it the user manual. + - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass + blocking not filtering and only does it if blocks aren't enforced. + Reported by: Robert Klemme + - FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors + As of 2021 they no longer handle donations for foreign organisations + due to lack of resources. + - FAQ: Remove an obsolete comment with a link to the long-gone PDF manual. + - FAQ: Add a link to the TODO list. + - FAQ: Change the sponsor amounts to USD slightly rounding the + converted amounts up to get simple numbers. + Receiving USD is apparently easier for SPI and SPI is + preferred by sponsors as they can send invoices. + - Advertise the client-tags CGI page in the user manual. + - Stop advertising the show-version CGI page which no longer exists. + - Add yet another reason why +prevent-compression may cause problems. + - Don't claim that contributors need ssh. It's only needed for committers. + - Replace obsolete CVS instructions with Git instructions. + - Remove an obsolete comment + +- Config file changes: + - Change the suggested default-server-timeout to 5 to match the + suggested keep-alive-timeout. Otherwise using the defaults would + result in Privoxy reducing the default-server-timeout and logging + an error message. + Sponsored by: Robert Klemme + - Update the 'debug 1' description. + - Add a missing 'client-specific-tag' directive. + - Comment out trusted-cgi-referer pointing to example.org. + +- Action file improvements: + - Block requests to /(.*/)?piwik\.php + - Block requests to .connectaserver.de/ + - Block requests to pixel.inforsea.com/ + - Block requests to t.vi-serve.com/ + - Block requests to .ioam.de/ + - Block requests to t.9gag.com/img.gif + - Block requests to .pixel.parsely.com/ as image + - Block requests to pixel.wp.com/ + - Disable fast-redirects for .librarything.com/ + - Disable fast-redirects for issue.freebsdfoundation.org/ + - Disable fast-redirects for .twitter.com/.*origin=http + - Unblock belco24.de/ + - Add fast-redirects exception for .wikipedia.org/ + - Add fast-redirects exception for oss-fuzz.com/ + - Disable fast-redirects for .consensu.org/delivery/pixel\.php + and block the requests as image instead + - Unblock .adbinstaller.com/ + Reported by lvm in #942. + - Unblock .adbshell.com + Reported by lvm in #942. + - Unblock .tagesschau.de/ + - Disable fast-redirects for collector.githubapp.com/ + and block requests to it as image instead + - Unblock 'ada*.' + - Add fast-redirects{} exception for sourcepoint.vice.com/ + - Unblock adaway.org/ + Reported by DRS David Soft in AF#945. + - Change two block reasons that previously were the same. + Sponsored by: Robert Klemme + - Added a +delay-response{} test. + - Updated the location of the development version + of default.action.master. + +- Privoxy-Log-Parser: + - Added a --keep-date option to keep the date in highlighted messages. + - Highlight new log messages. + - Make gather_loglevel_clf_stats() more tolerant. While at it, + count all CLF messages as requests, even if the request is invalid. + - Only show HTTP version distribution if at least one version has been detected. + - Only show crunch statistics if crunches were detected. + - Warn if the request counts differ. + - Generate statistics if the log only contains LOG_LEVEL_CLF messages + so it can be used with vanilla webserver logs. + Previously Privoxy-specific "Request:" messages were required. + - Align the client-HTTP-version distribution like other distributions + - Bump version to 0.9.1 + - Include status code distribution in the stats. + - Let the statistics include the size of the content Privoxy + transferred excluding HTTP headers. + - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST. + It's no longer necessary to count both LOG_LEVEL_REQUEST and + LOG_LEVEL_CRUNCH messages to get the total number of requests. + - Leverage the LOG_LEVEL_CLF message to gather statistics that where + previously taken from LOG_LEVEL_HEADER lines. This results in less + confusing results if https inspection is enabled in which case there + are two LOG_LEVEL_HEADER lines with request lines. + Sponsored by: Robert Klemme + - Properly highlight the filter results message. Previously a brace got lost. + - Prefer the number of CLF lines to get the total number of requests + as it works with older Privoxy versions as well. + +- Privoxy-Regression-Test: + - Turn curl's globbing mode off so we can allow more characters in URLs. + - Allow '[' and ']' in URLs. + - Include the action file when complaining about missing Sticky Actions. + - Fix a sentence in the documentation. + - Bump version to 0.7.1 + +- url-pattern-translator: + - Detect a couple of pattern prefixes case-insensitively. + Sponsored by: Robert Klemme + - Skip CLIENT-TAG patterns. + Sponsored by: Robert Klemme + - Skip patterns that have already been converted. + It should now be safe to "convert" a file multiple times. + Sponsored by: Robert Klemme + - Add the new 'PCRE-HOST-PATTERN:' prefix. + Sponsored by: Robert Klemme + +*** Version 3.0.28 stable *** + +- Bug fixes for regressions in 3.0.27: + - Fixed misplaced parentheses. + Reported by David Binderman. + - Changed two regression tests to depend on config directive + enable-remote-toggle instead of FEATURE_TOGGLE. + +*** Version 3.0.27 stable *** + +- General improvements: + - Add a receive-buffer-size directive which can be used to + set the size of the previously statically allocated buffer + in handle_established_connection(). + Increasing the buffer size increases Privoxy's memory usage but + can lower the number of context switches and thereby reduce the + CPU usage and potentially increase the throughput. + This is mostly relevant for fast network connections and + large downloads that don't require filtering. + Sponsored by: Robert Klemme + - Add a listen-backlog directive which specifies the backlog + value passed to listen(). + Sponsored by: Robert Klemme + - Add an enable-accept-filter directive which allows to + toggle accept filter support at run time when compiled + with FEATURE_ACCEPT_FILTER support. + It makes testing more convenient and now that it's + optional we can emit an error message if enabling + the accept filter fails. + Sponsored by: Robert Klemme + - Add a delay-response{} action. + This is useful to tar pit JavaScript requests that + are endlessly retried in case of blocks. It can also + be used to simulate a slow Internet connection. + Sponsored by: Robert Klemme + - Add a 'trusted-cgi-referrer' directive. + It allows to configure another page or site that can be used + to reach sensitive CGI resources. + Sponsored by: Robert Klemme + - Add a --fuzz mode which exposes Privoxy internals to input + from files or stdout. + Mainly tested with American Fuzzy Lop. For details see: + https://www.fabiankeil.de/talks/fuzzing-on-freebsd/ + This work was partially funded with donations and done + as part of the Privoxy month in 2015. + - Consistently use the U(ngreedy) flag in the 'img-reorder' filter. + - listen_loop(): Reuse a single thread attribute object + The object doesn't change and creating a new one for + every thread is a waste of (CPU) time. + Sponsored by: Robert Klemme + - Free csp resources in the thread that belongs to the csp instead + of the main thread which has enough on its plate already. + Sponsored by: Robert Klemme + - Improve 'socket timeout reached' message. + Log the timeout that was triggered and downgrade the + log level to LOG_LEVEL_CONNECT to reduce the log noise + with common debug settings. + The timeout isn't necessary the result of an error and + usually merely indicates that Privoxy's socket timeout + is lower than the relevant timeouts used by client and + server. + Sponsored by: Robert Klemme + - Explicitly taint the server socket in case of CONNECT requests. + This doesn't fix any known problems, but makes + some log messages less confusing. + - Let write_pid_file() terminate if the pid file can't be opened. + Logging the issue at info level is unlikely to help. + - log_error(): Reduce the mutex-protected area by not using a + heap-allocated buffer that is shared between all threads. + This increases performance and reduces the latency with + verbose debug settings and multiple concurrent connections. + Sponsored by: Robert Klemme + - Let zalloc() use calloc() if it's available. + In some situations using calloc() can be faster than + malloc() + memset() and it should never be slower. + In the real world the impact of this change is not + expected to be noticeable. + Sponsored by: Robert Klemme + - Never use select() when poll() is available. + On most platforms select() is limited by FD_SETSIZE while + poll() is not. This was a scaling issue for multi-user setups. + Using poll() has no downside other than the usual risk + that code modifications may introduce new bugs that have + yet to be found and fixed. + At least in theory this commit could also reduce the latency + when there are lots of connections and select() would use + "bit fields in arrays of integers" to store file descriptors. + Another side effect is that Privoxy no longer has to stop + monitoring the client sockets when pipelined requests are + waiting but can't be read yet. + This code keeps the select()-based code behind ifdefs for + now but hopefully it can be removed soonish to make the + code more readable. + Sponsored by: Robert Klemme + - Add a 'reproducible-tarball-dist' target. + It's currently separate from the "tarball-dist" target + because it requires a tar implementation with mtree spec + support. + It's far from being perfect and does not enforce a + reproducible mode, but it's better than nothing. + - Use arc4random() if it's available. + While Privoxy doesn't need high quality pseudo-random numbers + there's no reason not to use them when we can and this silences + a warning emitted by code checkers that can't tell whether or not + the quality matters. + - Show the FEATURE_EXTERNAL_FILTERS status on the status page. + Better late than never. Previously a couple of tests weren't + executed as Privoxy-Regression-Test couldn't detect that the + FEATURE_EXTERNAL_FILTERS dependency was satisfied. + - Ditch FEATURE_IMAGE_DETECT_MSIE. + It's an obsolete workaround we inherited from Junkbuster + and was already disabled by default. + Users that feel the urge to work around issues with + image requests coming from an Internet Explorer version + from more than 15 years ago can still do this using tags. + - Consistently use strdup_or_die() instead of strdup() in + cases where allocation failures aren't expected. + Using strdup_or_die() allows to remove a couple of explicit + error checks which slightly reduces the size of the binary. + - Insert a refresh tag into the /client-tags CGI page when + serving it while a client-specific tag is temporarily enabled. + This makes it less likely that the user ends up + looking at tag state that is out of date. + - Use absolute URLs in the client-tag forms. + It's more consistent with the rest of the CGI page + URLs and makes it more convenient to copy the forms + to external pages. + - cgi_error_disabled(): Use status code 403 and an appropriate response line + - Use a dedicated CGI handler to deal with tag-toggle requests + As a result the /client-tags page is now safe to reach without + trusted Referer header which makes bookmarking or linking to + it more convenient. + Finally, refreshing the /client-tags page to show the + current state can no longer unintentionally repeat the + previous toggle request. + - Don't add a "Connection" header for CONNECT requests. + Explicitly sending "Connection: close" is not necessary and + apparently it causes problems with some forwarding proxies + that will close the connection prematurely. + Reported by Marc Thomas. + - Fix compiler warnings. + +- Bug fixes: + - rfc2553_connect_to(): Properly detect and log when poll() + reached the time out. Previously this was logged as: + Could not connect to [...]: No error: 0. + which isn't very helpful. + Sponsored by: Robert Klemme + - add_tag_for_client(): Set time_to_live properly. + Previously the time_to_live was always set for the first tag. + Attempts to temporarily enable a tag would result in enabling + it permanently unless no tag was enabled already. + - Revert r1.165 which didn't perform as advertised. + While the idea was to use "https:// when creating links + for the user manual on the website", the actual effect + was to use "https://" when Privoxy was supposed to serve + the user manual itself. + Reported by Yossi Zahn on Privoxy-devel@. + - socks5_connect(): Fail in case of unsupported address types. + Previously they would not be detected right away and + Privoxy would fail later on with an error message that + didn't make it obvious that the problem was socks-related. + So far, no such problems have actually been reported. + - socks5_connect(): Properly deal with socks replies that + contain IPv6 addresses. + Previously parts of the reply were left unread and + later on treated as invalid HTTP response data. + Fixes #904 reported by Danny Goossen who also provided + the initial version of this patch. + +- Action file improvements: + - Unblock 'msdn.microsoft.com/'. + It (presumably) isn't used to serve the kind of ads Privoxy should + block by default but happens to serve lots of pages with URLs that + are likely to result in false positives. + Reported by bugreporter1694 in AF#939. + - Disable gif deanimation for requests tagged with CSS-REQUEST. + The action will ignore content that isn't considered text + anyway and explicitly disabling it makes this more obvious + if "action" debugging (debug 65536) is enabled while + "gif deanimation" debugging (debug 256) isn't. + - Explicitly disable HTML filters for requests with CSS-REQUEST tag. + The filters are unlikely to break CSS files but executing + them without (intentionally) getting any hits is a waste of + cpu time and makes the log more noisy when running with + "debug 64". + - Unblock 'adventofcode.com/'. + Reported by Clint Adams in Debian bug #848211. + Fixes Roland's AF#937. + - Unblock 'adlibris.com'. + Reported by Wyrex in #935 + - Unblock .golang.org/ + - Add fast-redirects exception for '.youtube.com/.*origin=http' + +- Privoxy-Log-Parser: + - Don't gather host and resource statistics if they aren't requested. + While the performance impact seems negligible this significantly + reduces the memory usage if there are lots of requests. + - Bump version as the behaviour (slightly) changed. + - Count connection failures as well in statistics mode. + Sponsored by: Robert Klemme + - Count connection timeouts as well in statistics mode. + Sponsored by: Robert Klemme + - Fix an 'uninitialized value' warning when generating + statistics for a log file without response headers. + While privoxy-log-parser was supposed to detect this already, + the check was flawed and the message the user didn't see was + somewhat confusing anyway. + Now the message is less confusing, more helpful and actually printed. + Reported by: Robert Klemme + +- Documentation improvements: + - Refer to the git sources instead of CVS. + - Use GNU/Linux when referring to the OS instead of the kernel. + - Add FAQ entry for what to do if editing the config file is access denied. + - Add brief HTTP/2 FAQ. + - Add a small fuzzing section to the developer documentation. + - Add a client-header-tagger{client-ip-address} example. + - Stop suggesting that Privoxy is an anonymizing proxy. + The term could lead to Privoxy users overestimating + what it can do on its own (without Tor). + - Make it more obvious that SPI accepts Paypal, too. + Currently most donations are made through the Paypal account + managed by Zwiebelfreunde e.V. and a more even distribution + would be useful. + - Suggest to log applying actions as well when reproducing problems. + - Explicitly mention that Privoxy binaries are built by individuals + on their own systems. Buyer beware! + - Mention the release feed on the homepage. + - Remove a mysterious comment with a GNU FDL link as it isn't + useful and could confuse license scanners. + In May 2002 it was briefly claimed that "this document" was covered + by the GNU FDL. The commit message (r1.5) doesn't explain the motivation + or whether all copyright holders were actually asked and agreed to the + declared license change. + It's thus hard to tell whether or not the license change was legit, + but luckily two days later the "doc license" was "put" "back to GPL" + anyway (r1.6). + At the same time the offending comment with a link to the FDL + (not the GPL) was added for no obvious reason. + Now it's gone again. + +- Regression tests: + - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted + CGI request being rejected with status code 403 (instead of 200). + - Update test for /send-stylesheet and add another one + +- Templates: + - Consistently use https:// when linking to the Privoxy website. + - Remove SourceForge references in Copyright header. + - Remove a couple of SourceForge references in a comment. + While at it, fix the grammar. + - Move the site-specific documentation block before the generic one. + While most Privoxy installations don't have a site-specific + documentation block, in cases were it exists it's likely to + be more relevant than the generic one. + Showing it first makes it less likely that users stop reading + before they reach it, especially on pages that don't fit on + the screen. + +- Build system improvements: + - Prefer openjade to jade. On some systems Jade produces + HTML with unescaped ampersands in URLs. + - Prefer OpenSP to SP to be consistent. + - Have Docbook generated HTML files be straight ASCII. + Dealing with a mixture of ISO-8859 and UTF-8 files is problematic. + - Echo the filename to stderr for 'make dok-tidy'. + Make it a bit easier to find errors in docbook generated HTML. + - Warn when still using select(). + - Warn when compiling without calloc(). + - Make it more obvious that the --with-fdsetsize configure switch + is pointless if poll() is available. + - Remove support for AmigaOS. + - Update windows build system to use supported software. + The cygwin gcc -mno-cygwin option is no longer supported, so + convert the windows build system to use the cygwin cross-compiler + to build "native" code. + - Add --enable-static-linking option for configure + does the same thing as LDFLAGS=-static; ./configure + but nicer than mixing evars and configure options. + *** Version 3.0.26 stable *** - Bug fixes: @@ -26,8 +544,7 @@ ChangeLog for Privoxy - Infrastructure improvements: - Add perl script to generate an RSS feed for the packages - Submitted by "Unknown": - https://lists.privoxy.org/pipermail/privoxy-devel/2016-July/000068.html + Submitted by "Unknown". - Build system improvements: - strptime.h: fix a compiler warning about ambiguous else. @@ -1549,7 +2066,7 @@ ChangeLog for Privoxy if connection-sharing is enabled. - A TODO list has been added to the source tarball to give potential volunteers a better idea of what the current goals are.
