Previously they - could cause memory corruption in configurations that allowed - the limit to be reached. - - Proxy authentication headers are removed unless the new directive - enable-proxy-authentication-forwarding is used. Forwarding the - headers potentionally allows malicious sites to trick the user - into providing them with login information. - Reported by Chris John Riley. - - Compiles on OS/2 again now that unistd.h is only included - on platforms that have it. + - Fixed a DoS issue in case of client requests with incorrect + chunk-encoded body. When compiled with assertions enabled + (the default) they could previously cause Privoxy to abort(). + Reported by Matthew Daley. + - Fixed multiple segmentation faults and memory leaks in the + pcrs code. This fix also increases the chances that an invalid + pcrs command is rejected as such. Previously some invalid commands + would be loaded without error. Note that Privoxy's pcrs sources + (action and filter files) are considered trustworthy input and + should not be writable by untrusted third-parties. + - Fixed an 'invalid read' bug which could at least theoretically + cause Privoxy to crash. So far, no crashes have been observed. + - Compiles with --disable-force again. Reported by Kai Raven. + - Client requests with body that can't be delivered no longer + cause pipelined requests behind them to be rejected as invalid. + Reported by Basil Hussain. - General improvements: - - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status. - - A couple of assert()s that could theoretically dereference - NULL pointers in debug builds have been relocated. - - Added an LSB info block to the generic start script. - Based on a patch from Natxo Asenjo. - - The max-client-connections default has been changed to 128 - which should be more than enough for most setups. + - If a pcrs command is rejected as invalid, Privoxy now logs + the cause of the problem as text. Previously the pcrs error + code was logged. + - The tests are less likely to cause false positives. - Action file improvements: - - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which - caused too man false positives. - Reported by u302320 in #360284, additional feedback from Adam Piggott. - - Unblock '.advrider.com/' and '/.*ADVrider'. - Anonymously reported in #3603636. - - Stop blocking '/js/slider\.js'. - Reported by Adam Piggott in #3606635 and _lvm in #2791160. - -- Filter file improvements: - - Added an iframes filter. - -- Documentation improvements: - - The whole GPLv2 text is included in the user manual now, - so Privoxy can serve it itself and the user can read it - without having to wade through GPLv3 ads first. - - Properly numbered and underlined a couple of section titles - in the config that where previously overlooked due to a flaw - in the conversion script. Reported by Ralf Jungblut. - - Improved the support instruction to hopefully make it harder to - unintentionally provide insufficient information when requesting - support. Previously it wasn't obvious that the information we need - in bug reports is usually also required in support requests. - - Removed documentation about packages that haven't been provided - in years. - -- Privoxy-Regression-Test: - - Only log the test number when not running in verbose mode - The position of the test is rarely relevant and it previously - wasn't exactly obvious which one of the numbers was useful to - repeat the test with --test-number. - -- GNUmakefile improvements: - - Factor generate-config-file out of config-file to make testing - more convenient. - - The clean target now also takes care of patch leftovers. - -*** Version 3.0.20 beta *** - -- Bug fixes: - - Client sockets are now properly shutdown and drained before being - closed. This fixes page truncation issues with clients that aggressively - pipeline data on platforms that otherwise discard already written data. - The issue mainly affected Opera users and was initially reported - by Kevin in #3464439, szotsaki provided additional information to track - down the cause. - - Fix latency calculation for shared connections (disabled by default). - It was broken since their introduction in 2009. The calculated latency - for most connections would be 0 in which case the timeout detection - failed to account for the real latency. - - Reject URLs with invalid port. Previously they were parsed incorrectly and - characters between the port number and the first slash were silently - dropped as shown by curl test 187. - - The default-server-timeout and socket-timeout directives accept 0 as - valid value. - - Fix a race condition on Windows that could cause Privoxy to become - unresponsive after toggling it on or off through the taskbar icon. - Reported by Tim H. in #3525694. - - Fix the compilation on Windows when configured without IPv6 support. - - Fix an assertion that could cause debug builds to abort() in case of - socks5 connection failures with "debug 2" enabled. - - Fix an assertion that could cause debug builds to abort() if a filter - contained nul bytes in the replacement text. - -- General improvements: - - Significantly improved keep-alive support for both client and server - connections. - - New debug log level 65536 which logs all actions that were applied to - the request. - - New directive client-header-order to forward client headers in a - different order than the one in which they arrived. - - New directive tolerate-pipelining to allow client-side pipelining. - If enabled (3.0.20 beta enables it by default), Privoxy will keep - pipelined client requests around to deal with them once the current - request has been served. - - New --config-test option to let Privoxy exit after checking whether or not - the configuration seems valid. The limitations noted in TODO #22 and #23 - still apply. Based on a patch by Ramkumar Chinchani. - - New limit-cookie-lifetime{} action to let cookies expire before the end - of the session. Suggested by Rick Sykes in #1049575. - - Increase the hard-coded maximum number of actions and filter files from - 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage - and recompiling wasn't an option for all Privoxy users that reached the - limit. - - Add support for chunk-encoded client request bodies. Previously - chunk-encoded request bodies weren't guaranteed to be forwarded correctly, - so this can also be considered a bug fix although chunk-encoded request - bodies aren't commonly used in the real world. - - Add support for Tor's optimistic-data SOCKS extension, which can reduce the - latency for requests on newly created connections. Currently only the - headers are sent optimistically and only if the client request has already - been read completely which rules out requests with large bodies. - - After preventing the client from pipelining, don't signal keep-alive - intentions. When looking at the response headers alone, it previously - wasn't obvious from the client's perspective that no additional responses - should be expected. - - Stop considering client sockets tainted after receiving a request with body. - It hasn't been necessary for a while now and unnecessarily causes test - failures when using curl's test suite. - - Allow HTTP/1.0 clients to signal interest in keep-alive through the - Proxy-Connection header. While such client are rare in the real world, it - doesn't hurt and couple of curl tests rely on it. - - Only remove duplicated Content-Type headers when filters are enabled. - If they are not it doesn't cause ill effects and the user might not want it. - Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not - an error in Privoxy and is unlikely to cause any problems in general. - Anonymously reported in #3599335. - - Set the socket option SO_LINGER for the client socket. - - Move several variable declarations to the beginning of their code block. - It's required when compiling with gcc 2.95 which is still used on some - platforms. Initial patch submitted by Simon South in #3564815. - - Optionally try to sanity-check strptime() results before trusting them. - Broken strptime() implementations have caused problems in the past and - the most recent offender seems to be FreeBSD's libc (standards/173421). - - When filtering is enabled, let Range headers pass if the range starts at - the beginning. This should work around (or at least reduce) the video - playback issues with various Apple clients as reported by Duc in #3426305. - - Do not confuse a client hanging up with a connection time out. If a client - closes its side of the connection without sending a request line, do not - send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition - properly. - - Allow closing curly braces as part of action values as long as they are - escaped. - - On Windows, the logfile is now written before showing the GUI error - message which blocks until the user acknowledges it. - Reported by Adriaan in #3593603. - - Remove an unreasonable parameter limit in the CGI interface. The new - parameter limit depends on the memory available and is currently unlikely - to be reachable, due to other limits in both Privoxy and common clients. - Reported by Andrew on ijbswa-users@. - - Decrease the chances of parse failures after requests with unsupported - methods were sent to the CGI interface. - -- Action file improvements: - - Remove the comment that indicated that updated default.action versions - are released on their own. - - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/' - - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'. - Reported by Ryan Farmer in #3496116. - - Unblock '/.*Bugtracker'.

Reported by Zeno Kugy in #3520260. + - '.sify.com/' is no longer blocked. Apparently it is not actually + a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@. + - Unblock banners on .amnesty.de/ which aren't ads. - Documentation improvements: - - Revised all OS X sections due to new packaging module (OSXPackageBuilder). - - Update the list of supported operating systems to clarify that all Windows - versions after 95 are expected to work and note that the platform-specific - code for AmigaOS and QNX currently isn't maintained. - - Update 'Signals' section, the only explicitly handled signals are SIGINT, - SIGTERM and SIGHUP. - - Add Haiku to the list of operating systems on which Privoxy is known to - run. - - Add DragonFly to the list of BSDs on which Privoxy is known to run. - - Removed references to redhat-specific documentation set since it no longer - exists. - - Removed references to building PDFs since we no longer do so. - - Multiple listen-address directives are supported since 3.0.18, correct the - documentation to say so. - - Remove bogus section about long and short being preferable to int. - - Corrected some Internet JunkBuster references to Privoxy. - - Removed references to www.junkbusters.com since it is no longer - maintained. Reported by Angelina Matson. - - Various grammar and spelling corrections - - Add a client-header-tagger{} example for disabling filtering for range - requests. - - Correct a URL in the "Privoxy with Tor" FAQ. - - Spell 'refresh-tags' correctly. Reported by Don in #3571927. - - Sort manpage options alphabetically. - - Remove an incorrect sentence in the toggle section. The toggle state - doesn't affect whether or not the Windows version uses the tray icon. - Reported by Zeno Kugy in #3596395. - - Add new contributors since 3.0.19. - -- Log message improvements: - - When stopping to watch a client socket due to pipelining, additionally log - the socket number. - - Log the client socket and its condition before closing it. This makes it - more obvious that the socket actually gets closed and should help when - diagnosing problems like #3464439. - - In case of SOCKS5 failures, do not explicitly log the server's response. - It hasn't helped so far and the response can already be logged by enabling - "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84. - - Relocate the connection-accepted message from listen_loop() to serve(). - This way it's printed by the thread that is actually serving the - connection which is nice when grepping for thread ids in log files. - -- Code cleanups: - - Remove compatibility layer for versions prior to 3.0 since it has been - obsolete for more than 10 years now. - - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since - they aren't used in this file. - - Removed the 'Functions declared include:' comment sections since they tend - to be incomplete, incorrect and out of date and the benefit seems - questionable. - - Various comment grammar and comprehensibility improvements. - - Remove a pointless fflush() call in chat(). Flushing all streams pretty - much all the time for no obvious reason is ridiculous. - - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower() - definition from there, too. - - Relocate ijb_isdigit()'s definition to project.h. - - Rename ijb_foo macros to privoxy_foo. - - Add malloc_or_die() which will allow to simplify code paths where malloc() - failures don't need to be handled gracefully. - - Add strdup_or_die() which will allow to simplify code paths where strdup() - failures don't need to be handled gracefully. - - Replace strdup() calls with strdup_or_die() calls where it's safe and - simplifies the code. - - Fix white-space around parentheses. - - Add missing white-space behind if's and the following parentheses. - - Unwrap a memcpy() call in resolve_hostname_to_ip(). - - Declare pcrs_get_delimiter()'s delimiters[] static const. - - Various optimisations to remove dead code and merge inefficient code - structures for improved clarity, performance or code compactness. - - Various data type corrections. - - Change visibility of several code segments when compiling without - FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity. - - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range. - Fixes a clang complaint. - - Fix an error message in get_last_url() nobody is supposed to see. - Reported by Matthew Fischer in #3507301. - - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew - Fischer in #3507304. - - Shorten ssplit()'s prototype by removing the last two arguments. We always - want to skip empty fields and ignore leading delimiters, so having - parameters for this only complicates the API. - - Use an enum for the type of the action value. - - Rename action_name's member takes_value to value_type as it isn't used as - boolean. - - Turn family mismatches in match_sockaddr() into fatal errors. - - Let enlist_unique_header() verify that the caller didn't pass a header - containing either \r or \n. - - Change the hashes used in load_config() to unsigned int. That's what - hash_string() actually returns and using a potentially larger type - is at best useless. - - Use privoxy_tolower() instead of vanilla tolower() with manual casting of - the argument. - - Catch ssplit() failures in parse_cgi_parameters(). - -- Privoxy-Regression-Test: - - Add an 'Overwrite condition' directive to skip any matching tests before - it. As it has a global scope, using it is more convenient than clowning - around with the Ignore directive. - - Log to STDOUT instead of STDERR. - - Include the Privoxy version in the output. - - Various grammar and spelling corrections in documentation and code. - - Additional tests for range requests with filtering enabled. - - Tests with mostly invalid range request. - - Add a couple of hide-if-modified-since{} tests with different date formats. - - Cleaned up the format of the regression-tests.action file to match the - format of default.action. - - Remove the "Copyright" line from print_version(). When using --help, every - line of screen space matters and thus shouldn't be wasted on things the - user doesn't care about. - -- Privoxy-Log-Parser: - - Improve the --statistics performance by skipping sanity checks for input - that shouldn't affect the results anyway. Add a --strict-checks option - that enables some of the checks again, just in case anybody cares. - - The distribution of client requests per connection is included in - the --statistic output. - - The --accept-unknown-messages option has been removed and the behavior - is now the default. - - Accept and (mostly) highlight new log messages introduced with - Privoxy 3.0.20. - -- uagen: - - Bump generated Firefox version to 17. - -- GNUmakefile improvements: - - The dok-tidy target no longer taints documents with a tidy-mark - - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in - #3505445. - - Remove tidy's clean flag as it changes the scope of attributes. - Link-specific colors end up being applied to all text. Reported by Adam - Piggott in #3569551. - - Leave it up to the user whether or not smart tags are inserted. - - Let w3m itself do the line wrapping for the config file. It works better - than fmt as it can honour pre tags causing less unintentional line breaks. - - Ditch a pointless '-r' passed to rm to delete files. - - The config-file target now requires less manual intervention and updates - the original config. - - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the - AUTHORS file so the names are right. - - Stop pretending that lynx and links are supported for the documentation. - -- configure improvements: - - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads - implementation is contained in its system library, libroot, so no - additional library needs to be searched. - Patch submitted by Simon South in #3564815. - - Additional Haiku-specific improvements. Disable checks intended for - multi-user systems as Haiku is presently single-user. Group Haiku-specific - settings in their own section, following the pattern for Solaris, OS/2 and - AmigaOS. Add additional library-related settings to remove the need for - providing configure with custom LDFLAGS. - Submitted by Simon South in #3574538. + - The 'Would you like to donate?' section now also contains + a "Paypal" address. + - The list of supported operating systems has been updated. + - The existence of the SF support and feature trackers has been + deemphasized because they have been broken for months. + Most of the time the mailing lists still work. + - The claim that default.action updates are sometimes released + on their own has been removed. It hasn't happened in years. + - Explicitly mention that Tor's port may deviate from the default + when using a bundle.
