+ChangeLog for Privoxy 3.0.32
--------------------------------------------------------------------
-*** Version 3.0.21 stable ***
+- Security/Reliability:
+ - ssplit(): Remove an assertion that could be triggered with a
+ crafted CGI request.
+ Commit 2256d7b4d67. OVE-20210203-0001.
+ Reported by: Joshua Rogers (Opera)
+ - cgi_send_banner(): Overrule invalid image types. Prevents a
+ crash with a crafted CGI request if Privoxy is toggled off.
+ Commit e711c505c48. OVE-20210206-0001.
+ Reported by: Joshua Rogers (Opera)
+ - socks5_connect(): Don't try to send credentials when none are
+ configured. Fixes a crash due to a NULL-pointer dereference
+ when the socks server misbehaves.
+ Commit 85817cc55b9. OVE-20210207-0001.
+ Reported by: Joshua Rogers (Opera)
+ - chunked_body_is_complete(): Prevent an invalid read of size two.
+ Commit a912ba7bc9c. OVE-20210205-0001.
+ Reported by: Joshua Rogers (Opera)
+ - Obsolete pcre: Prevent invalid memory accesses with an invalid
+ pattern passed to pcre_compile(). Note that the obsolete pcre code
+ is scheduled to be removed before the 3.0.33 release. There has been
+ a warning since 2008 already.
+ Commit 28512e5b624. OVE-20210222-0001.
+ Reported by: Joshua Rogers (Opera)
- 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 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.
+ - Properly parse the client-tag-lifetime directive. Previously it was
+ not accepted as an obsolete hash value was being used.
+ Reported by: Joshua Rogers (Opera)
+ - decompress_iob(): Prevent reading of uninitialized data.
+ Reported by: Joshua Rogers (Opera).
+ - decompress_iob(): Don't advance cur past eod when looking
+ for the end of the file name and comment.
+ - decompress_iob(): Cast value to unsigned char before shifting.
+ Prevents a left-shift of a negative value which is undefined behaviour.
+ Reported by: Joshua Rogers (Opera)
+ - gif_deanimate(): Confirm that that we have enough data before doing
+ any work. Fixes a crash when fuzzing with an empty document.
+ Reported by: Joshua Rogers (Opera).
+ - buf_copy(): Fail if there's no data to write or nothing to do.
+ Prevents undefined behaviour "applying zero offset to null pointer".
+ Reported by: Joshua Rogers (Opera)
+ - log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
+ being used while fuzzing.
+ Reported by: Joshua Rogers (Opera).
+ - Respect DESTDIR when considering whether or not to install
+ config files with ".new" extension.
+ - OpenSSL ssl_store_cert(): Fix two error messages.
+ - Fix a couple of format specifiers.
+ - Silence compiler warnings when compiling with NDEBUG.
+ - fuzz_server_header(): Fix compiler warning.
+ - fuzz_client_header(): Fix compiler warning.
+ - cgi_send_user_manual(): Also reject requests if the user-manual
+ directive specifies a https:// URL. Previously Privoxy would try and
+ fail to open a local file.
- 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.
+ - Log the TLS version and the the cipher when debug 2 is enabled.
+ - ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
+ - ssl_send_certificate_error(): End the body with a single new line.
+ - serve(): Increase the chances that the host is logged when closing
+ a server socket.
+ - handle_established_connection(): Add parentheses to clarify an expression
+ Suggested by: David Binderman
+ - continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE
+ if process_encrypted_request() fails. This makes it more obvious that the
+ connection will not be reused. Previously serve() relied on
+ CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
+ Inspired by a patch from Joshua Rogers (Opera).
+ - decompress_iob(): Add periods to a couple of log messages
+ - Terminate the body of the HTTP snipplets with a single new line
+ instead of "\r\n".
+ - configure: Add --with-assertions option and only enable assertions
+ when it is used
+ - windows build: Use --with-brotli and --with-mbedtls by default and
+ enable dynamic error checking.
+ - gif_deanimate(): Confirm we've got an image before trying to write it
+ Saves a pointless buf_copy() call.
+ - OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
- 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.
+ - Disable fast-redirects for .golem.de/
+ - Unblock requests to adri*.
+ - Block requests for trc*.taboola.com/
+ - Disable fast-redirects for .linkedin.com/
- 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.
+ - Make the second pcrs job of the img-reorder filter greedy again.
+ The ungreedy version broke the img tags on:
+ https://bulk.fefe.de/scalability/.
-- 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/'.

-
-- Filter file improvements & bug fixes:
- - Add a referer tagger.
- - Reduce the likelihood that the google filter messes up HTML-generating
- JavaScript. Reported by Zeno Kugy in #3520260.
-
-- 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-Log-Parser:
+ - Highlight a few more messages.
+ - Clarify the --statistics output. The shown "Reused connections"
+ are server connections so name them appropriately.
+ - Bump version to 0.9.3.
- 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.
+ - Add the --check-bad-ssl option to the --help output.
+ - Bump version to 0.7.3.
-- 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.
+- Documentation:
+ - Add pushing the created tag to the release steps in the developer manual.
+ - Clarify that 'debug 32768' should be used in addition to the other debug
+ directives when reporting problems.
+ - Add a 'Third-party licenses and copyrights' section to the user manual.
