- Announcing Privoxy v.3.0.20 beta
+ Announcing Privoxy 3.0.34 stable
--------------------------------------------------------------------
-This is a beta release that introduces some new features and fixes a number of bugs, some of which are reasonably significant. 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. Previously the "crunch reason"
+ could also be highlighted when the URL contained a matching string.
+ The real crunch reason only occurs once per line, so there's no need
+ to continue looking for it after it has been found once.
+ While at it, add a comment with an example log line.
+
+- uagen:
+ - Bump version to 1.2.4.
+ - Update BROWSER_VERSION and BROWSER_REVISION to 102.0
+ to match the User-Agent of the current Firefox ESR.
+ - Explicitly document that changing the 'Gecko token' is suspicious.
+ - Consistently use a lower-case 'c' as copyright symbol.
+ - Bump copyright.
+ - Add 'aarch64' as Linux architecture.
+ - Add OpenBSD architecture 'arm64'.
+ - Stop using sparc64 as FreeBSD architecture.
+ It hasn't been supported for a while now.
+
+- Build system:
+ - Makefile: Add a 'dok' target that depends on the 'error' target
+ to show the "You are not using GNU make or did nor run configure"
+ message.
+ - configure: Fix --with-msan option.
+ Also (probably) reported by Andrew Savchenko.
+
+- macOS build system:
+ - Enable HTTPS inspection when building the macOS binary
+ (using OpenSSL as TLS library).
+
+- Documentation:
+ - Add OpenSSL to the list of libraries that may be licensed under the
+ Apache 2.0 license in which case the linked Privoxy binary has to be
+ distributed under the GPLv3 or later.
+ - config: Fix the documented ca-directory default value.
+ Reported by avoidr.
+ - Rebuild developer-manual and tidy with 'HTML Tidy for FreeBSD version 5.8.0'.
+ - Update developer manual with new macOS packaging instructions.
+ - Note that the FreeBSD installation instructions work for
+ ElectroBSD as well.
+ - Note that FreeBSD/ElectroBSD users can try to install Privoxy
+ as binary package using 'pkg'.
