One new feature (tolerate-pipelining) is enabled by default. See below for details. +Privoxy 3.0.34 fixes a few minor bugs and comes with a couple of +general improvements and new features. -------------------------------------------------------------------- -ChangeLog for Privoxy +ChangeLog for Privoxy 3.0.34 -------------------------------------------------------------------- -*** 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 receving 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. - -*** Version 3.0.19 Stable *** - - Bug fixes: - - Prevent a segmentation fault when de-chunking buffered content. - It could be triggered by malicious web servers if Privoxy was - configured to filter the content and running on a platform - where SIZE_T_MAX isn't larger than UINT_MAX, which probably - includes most 32-bit systems. On those platforms, all Privoxy - versions before 3.0.19 appear to be affected. - To be on the safe side, this bug should be presumed to allow - code execution as proving that it doesn't seems unrealistic. - - Do not expect a response from the SOCKS4/4A server until it - got something to respond to. This regression was introduced - in 3.0.18 and prevented the SOCKS4/4A negotiation from working. - Reported by qqqqqw in #3459781. + - Improve the handling of chunk-encoded responses by buffering the data + even if filters are disabled and properly keeping track of where the + various chunks are supposed to start and end. Previously Privoxy would + merely check the last bytes received to see if they looked like the + last-chunk. This failed to work if the last-chunk wasn't received in one + read and could also result in actual data being misdetected + as last-chunk. + Should fix: SF support request #1739. + Reported by: withoutname. + - remove_chunked_transfer_coding(): Refuse to de-chunk invalid data + Previously the data could get corrupted even further. + Now we simply pass the unmodified data to the client. + - gif_deanimate(): Tolerate multiple image extensions in a row. + This allows to deanimate all the gifs on: + https://commons.wikimedia.org/wiki/Category:Animated_smilies + Fixes SF bug #795 reported by Celejar. + - OpenSSL generate_host_certificate(): Use X509_get_subject_name() + instead of X509_get_issuer_name() to get the issuer for generated + website certificates so there are no warnings in the browser when using + an intermediate CA certificate instead of a self-signed root certificate. + Problem reported and patch submitted by Chakib Benziane. + - can_filter_request_body(): Fix a log message that contained a spurious u. + - handle_established_connection(): Check for pending TLS data from the client + before checking if data is available on the connection. + The TLS library may have already consumed all the data from the client + response in which case poll() and select() will not detect that data is + available to be read. + Sponsored by: Robert Klemme. + - ssl_send_certificate_error(): Don't crash if there's no certificate + information available. This is only relevant when Privoxy is built with + wolfSSL 5.0.0 or later (code not yet published). Earlier wolfSSL versions + or the other TLS backends don't seem to trigger the crash. + - socks5_connect(): Add support for target hosts specified as IPv4 address + Previously the IP address was sent as domain. - General improvements: - - Fix an off-by-one in an error message about connect failures. - - Use a GNUMakefile variable for the webserver root directory and - update the path. Sourceforge changed it which broke various - web-related targets. - - Update the CODE_STATUS description. + - Add a client-body-tagger action which creates tags based on + the content of the request body. + Sponsored by: Robert Klemme. + - When client-body filters are enabled, buffer the whole request + before opening a connection to the server. + Makes it less likely that the server connection times out + and we don't open a connection if the buffering fails anyway. + Sponsored by: Robert Klemme. + - Add periods to a couple of log messages. + - accept_connection(): Add missing space to a log message. + - Initialize ca-related defaults with strdup_or_die() so errors + aren't silently ignored. + - make_path: Use malloc_or_die() in cases where allocation errors + were already fatal anyway. + - handle_established_connection(): Improve an error message slightly. + - receive_client_request(): Reject https URLs without CONNECT request. + - Include all requests in the statistics if mutexes are available. + Previously in case of reused connections only the last request got + counted. The statistics still aren't perfect but it's an improvement. + - Add read_socks_reply() and start using it in socks5_connect() + to apply the socket timeout more consistently. + - socks5_connect(): Deal with domain names in the socks reply + - Add a filter for bundeswehr.de that hides the cookie and + privacy info banner. + +- Action file improvements: + - Disable filter{banners-by-size} for .freiheitsfoo.de/. + - Disable filter{banners-by-size} for freebsdfoundation.org/. + - Disable fast-redirects for consent.youtube.com/. + - Block requests to ups.xplosion.de/. + - Block requests for elsa.memoinsights.com/t. + - Fix a typo in a test. + - Disable fast-redirects for launchpad.net/. + - Unblock .eff.org/. + - Stop unblocking .org/.*(image|banner) which appears to be too generous + It let requests like: + https://stats.noblogs.org/piwik.php?action_name=anti%20gentrifizierungs%20fest&idsite=10175&rec=1&r=220192&h=17&m=7&s=44&url=https%3A%2F%2Fmuellemcalling.noblogs.org%2F&urlref=https%3A%2F%2Fmuellemcalling.noblogs.org%2Finfostande%2F&_id=&_idn=1&_refts=0&send_image=0&cookie=1&res=1366x768&pv_id=eqr7jX&pf_net=7&pf_srv=3&pf_tfr=2281&pf_dm1=156 + pass. + The example URL http://www.gnu.org/graphics/gnu-head-banner.png is + already unblocked due to .gnu.org being unblocked. + - Unblock adfd.org/. + - Disable filter{banners-by-link} for .eff.org/. + - Block requests to odb.outbrain.com/. + - Disable fast-redirects for .gandi.net/. + - Disable fast-redirects{} for .onion/.*/status/. + - Disable fast-redirects{} for twitter.com/.*/status/. + - Unblock pinkstinks.de/. + - Disable fast-redirects for .hagalil.com/. + +- Privoxy-Log-Parser: + - Bump version to 0.9.5. + - Highlight more log messages. + - Highlight the Crunch reason only once.
