The most prominent new feature is "keep-alive" support for -outgoing connections. + Announcing Privoxy 3.0.21 stable +-------------------------------------------------------------------- -See http://www.privoxy.org/3.0.11/user-manual/whatsnew.html for details. +Privoxy 3.0.21 stable is a bug-fix release for Privoxy 3.0.20 beta. +It addresses two security issues that affect all previous Privoxy +versions. -------------------------------------------------------------------- ChangeLog for Privoxy -------------------------------------------------------------------- +*** Version 3.0.21 stable *** + +- Bug fixes: + - On POSIX-like platforms, network sockets with file descriptor + values above FD_SETSIZE are properly rejected. 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 potentially 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. + +- 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. + +- 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. -*** Version 3.0.11 *** - -- On most platforms, outgoing connections can be kept alive and - reused if the server supports it. Whether or not this improves - things depends on the connection. -- When dropping privileges, membership in supplementary groups - is given up as well. Not doing that can lead to Privoxy running - with more rights than necessary and violates the principle of - least privilege. Users of the --user option are advised to update. - Thanks to Matthias Drochner for reporting the problem, - providing the initial patch and testing the final version. -- Passing invalid users or groups with the --user option - didn't lead to program exit. Regression introduced in 3.0.7. -- The match all section has been moved from default.action - to a new file called match-all.action. As a result the - default.action no longer needs to be touched by the user - and can be safely overwritten by updates. -- The standard.action file has been removed. Its content - is now part of the default.action file. -- In some situations the logged content length was slightly too low. -- Crunched requests are logged with their own log level. - If you used "debug 1" in the past, you'll probably want - to additionally enable "debug 1024", otherwise only passed - requests will be logged. If you only care about crunched - requests, simply replace "debug 1" with "debug 1024". -- The crunch reason has been moved to the beginning of the - crunch message. For HTTP URLs, the protocol is logged as well. -- Log messages are shortened by printing the thread id on its - own (as opposed to putting it inside the string "Privoxy()"). -- The config option socket-timeout has been added to control - the time Privoxy waits for data to arrive on a socket. -- Support for remote toggling is controlled by the configure - option --disable-toggle only. In previous versions it also - depended on the action editor and thus configuring with the - --disable-editor option would disable remote toggling support - as well. -- Requests with invalid HTTP versions are rejected. -- The template symbol @date@ can be used to include a date(1)-like - time string. Initial patch submitted by Endre Szabo. -- Responses from shoutcast servers are accepted again. - Problem reported and fix suggested by Stefan. -- The hide-forwarded-for-headers action has been replaced with - the change-x-forwarded-for{} action which can also be used to - add X-Forwarded-For headers. The latter functionality already - existed in Privoxy versions prior to 3.0.7 but has been removed - as it was often used unintentionally (by not using the - hide-forwarded-for-headers action). -- A "clear log" view option was added to the mingw32 version - to clear out all of the lines in the Privoxy log window. - Based on a patch submitted by T Ford. -- The mingw32 version uses "critical sections" now, which prevents - log message corruption under load. As a side effect, the - "no thread-safe PRNG" warning could be removed as well. -- The mingw32 version's task bar icon is crossed out and - the color changed to gray if Privoxy is toggled off. +- 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. ----------------------------------------------------------------- About Privoxy: ----------------------------------------------------------------- -Privoxy is a non-caching web proxy with advanced filtering -capabilities for enhancing privacy, modifying web page data, -managing HTTP cookies, controlling access, and removing ads, -banners, pop-ups and other obnoxious Internet junk.
