+ <h1 class="SECT1"><a name="WHATSNEW" id="WHATSNEW">3. What's New in this Release</a></h1>
+ <p><span class="APPLICATION">Privoxy 3.0.29</span> fixes a couple of memory leaks and introduces https inspection
+ which allows to filter encrypted requests and responses.</p>
+ <p>Changes in <span class="APPLICATION">Privoxy 3.0.29</span> stable:</p>
<ul>
<li>
- <p>Bug fixes:</p>
-
+ <p>Security/Reliability:</p>
<ul>
<li>
- <p>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.</p>
+ <p>Fixed memory leaks when a response is buffered and the buffer limit is reached or Privoxy is running out
+ of memory. Commits bbd53f1010b and 4490d451f9b. OVE-20201118-0001. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Fixed a memory leak in the show-status CGI handler when no action files are configured. Commit
+ c62254a686. OVE-20201118-0002. Sponsored by: Robert Klemme</p>
</li>
- </ul>
- </li>
-
- <li>
- <p>General improvements:</p>
-
- <ul>
- <li>
- <p>Fix an off-by-one in an error message about connect
- failures.</p>
- </li>
-
- <li>
- <p>Use a GNUMakefile variable for the webserver root directory
- and update the path. Sourceforge changed it which broke various
- web-related targets.</p>
- </li>
-
- <li>
- <p>Update the CODE_STATUS description.</p>
- </li>
- </ul>
- </li>
- </ul>
-
- <p>The following changes were made between 3.0.17 and 3.0.18:</p>
-
- <ul>
- <li>
- <p>Bug fixes:</p>
-
- <ul>
- <li>
- <p>If a generated redirect URL contains characters RFC 3986
- doesn't permit, they are (re)encoded. Not doing this makes
- Privoxy versions from 3.0.5 to 3.0.17 susceptible to HTTP
- response splitting (CWE-113) attacks if the
- +fast-redirects{check-decoded-url} action is used.</p>
- </li>
-
- <li>
- <p>Fix a logic bug that could cause Privoxy to reuse a server
- socket after it got tainted by a server-header-tagger-induced
- block that was triggered before the whole server response had
- been read. If keep-alive was enabled and the request following
- the blocked one was to the same host and using the same
- forwarding settings, Privoxy would send it on the tainted server
- socket. While the server would simply treat it as a pipelined
- request, Privoxy would later on fail to properly parse the
- server's response as it would try to parse the unread data from
- the first response as server headers for the second one.
- Regression introduced in 3.0.17.</p>
- </li>
-
- <li>
- <p>When implying keep-alive in client_connection(), remember that
- the client didn't. Fixes a regression introduced in 3.0.13 that
- would cause Privoxy to wait for additional client requests after
- receiving a HTTP/1.1 request with "Connection: close" set and
- connection sharing enabled. With clients which terminates the
- client connection after detecting that the whole body has been
- received it doesn't really matter, but with clients that don't
- the connection would be kept open until it timed out.</p>
- </li>
-
- <li>
- <p>Fix a subtle race condition between
- prepare_csp_for_next_request() and sweep(). A thread preparing
- itself for the next client request could briefly appear to be
- inactive. If all other threads were already using more recent
- files, the thread could get its files swept away under its feet.
- So far this has only been reproduced while stress testing in
- valgrind while touching action files in a loop. It's unlikely to
- have caused any actual problems in the real world.</p>
- </li>
-
- <li>
- <p>Disable filters if SDCH compression is used unless filtering
- is forced. If SDCH was combined with a supported compression
- algorithm, Privoxy previously could try to decompress it and
- ditch the Content-Encoding header even though the SDCH
- compression wasn't dealt with. Reported by zebul666 in
- #3225863.</p>
- </li>
-
- <li>
- <p>Make a copy of the --user value and only mess with that when
- splitting user and group. On some operating systems modifying the
- value directly is reflected in the output of ps and friends and
- can be misleading. Reported by zepard in #3292710.</p>
- </li>
-
- <li>
- <p>If forwarded-connect-retries is set, only retry if Privoxy is
- actually forwarding the request. Previously direct connections
- would be retried as well.</p>
- </li>
-
<li>
- <p>Fixed a small memory leak when retrying connections with IPv6
- support enabled.</p>
+ <p>Fixed a memory leak in the show-status CGI handler when no filter files are configured. Commit
+ 1b1370f7a8a. OVE-20201118-0003. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Remove an incorrect assertion in
- compile_dynamic_pcrs_job_list() It could be triggered by a pcrs
- job with an invalid pcre pattern (for example one that contains a
- lone quantifier).</p>
+ <p>Fixes a memory leak when client tags are active. Commit 245e1cf32. OVE-20201118-0004. Sponsored by:
+ Robert Klemme</p>
</li>
-
<li>
- <p>If the --user argument user[.group] contains a dot, always
- bail out if no group has been specified. Previously the intended,
- but undocumented (and apparently untested), behaviour was to try
- interpreting the whole argument as user name, but the detection
- was flawed and checked for '0' instead of '\0', thus merely
- preventing group names beginning with a zero.</p>
+ <p>Fixed a memory leak if multiple filters are executed and the last one is skipped due to a pcre error.
+ Commit 5cfb7bc8fe. OVE-20201118-0005.</p>
</li>
-
<li>
- <p>In html_code_map[], use a numeric character reference instead
- of ' which wasn't standardized before XHTML 1.0.</p>
+ <p>Prevent an unlikely dereference of a NULL-pointer that could result in a crash if
+ accept-intercepted-requests was enabled, Privoxy failed to get the request destination from the Host header
+ and a memory allocation failed. Commit 7530132349. CID 267165. OVE-20201118-0006.</p>
</li>
-
<li>
- <p>Fix an invalid free when compiled with
- FEATURE_GRACEFUL_TERMINATION and shut down through
- http://config.privoxy.org/die</p>
+ <p>Fixed memory leaks in the client-tags CGI handler when client tags are configured and memory allocations
+ fail. Commit cf5640eb2a. CID 267168. OVE-20201118-0007.</p>
</li>
-
<li>
- <p>In get_actions(), fix the "temporary" backwards compatibility
- hack to accept block actions without reason. It also covered
- other actions that should be rejected as invalid. Reported by
- Billy Crook.</p>
+ <p>Fixed memory leaks in the show-status CGI handler when memory allocations fail. Commit 064eac5fd0 and
+ commit fdee85c0bf3. CID 305233. OVE-20201118-0008.</p>
</li>
</ul>
</li>
-
<li>
<p>General improvements:</p>
-
<ul>
<li>
- <p>Privoxy can (re)compress buffered content before delivering it
- to the client. Disabled by default as most users wouldn't benefit
- from it.</p>
- </li>
-
- <li>
- <p>The +fast-redirects{check-decoded-url} action checks URL
- segments separately. If there are other parameters behind the
- redirect URL, this makes it unnecessary to cut them off by
- additionally using a +redirect{} pcrs command. Initial patch
- submitted by Jamie Zawinski in #3429848.</p>
- </li>
-
- <li>
- <p>When loading action sections, verify that the referenced
- filters exist. Currently missing filters only result in an error
- message, but eventually the severity will be upgraded to
- fatal.</p>
- </li>
-
- <li>
- <p>Allow to bind to multiple separate addresses. Patch set
- submitted by Petr Pisar in #3354485.</p>
- </li>
-
- <li>
- <p>Set socket_error to errno if connecting fails in
- rfc2553_connect_to(). Previously rejected direct connections
- could be incorrectly reported as DNS issues if Privoxy was
- compiled with IPv6 support.</p>
- </li>
-
- <li>
- <p>Adjust url_code_map[] so spaces are replaced with %20 instead
- of '+' While '+' can be used by client's submitting form data,
- this is not actually what Privoxy is using the lookups for. This
- is more of a cosmetic issue and doesn't fix any known
- problems.</p>
- </li>
-
- <li>
- <p>When compiled without FEATURE_FAST_REDIRECTS, do not silently
- ignore +fast-redirect{} directives</p>
- </li>
-
- <li>
- <p>Added a workaround for GNU libc's strptime() reporting
- negative year values when the parsed year is only specified with
- two digits. On affected systems cookies with such a date would
- not be turned into session cookies by the +session-cookies-only
- action. Reported by Vaeinoe in #3403560</p>
- </li>
-
- <li>
- <p>Fixed bind failures with certain GNU libc versions if no
- non-loopback IP address has been configured on the system. This
- is mainly an issue if the system is using DHCP and Privoxy is
- started before the network is completely configured. Reported by
- Raphael Marichez in #3349356. Additional insight from Petr
- Pisar.</p>
- </li>
-
- <li>
- <p>Privoxy log messages now use the ISO 8601 date format
- %Y-%m-%d. It's only slightly longer than the old format, but
- contains the full date including the year and allows sorting by
- date (when grepping in multiple log files) without hassle.</p>
- </li>
-
- <li>
- <p>In get_last_url(), do not bother trying to decode URLs that do
- not contain at least one '%' sign. It reduces the log noise and a
- number of unnecessary memory allocations.</p>
- </li>
-
- <li>
- <p>In case of SOCKS5 failures, dump the socks response in the log
- message.</p>
- </li>
-
- <li>
- <p>Simplify the signal setup in main().</p>
- </li>
-
- <li>
- <p>Streamline socks5_connect() slightly.</p>
- </li>
-
- <li>
- <p>In socks5_connect(), require a complete socks response from
- the server. Previously Privoxy didn't care how much data the
- server response contained as long as the first two bytes
- contained the expected values. While at it, shrink the buffer
- size so Privoxy can't read more than a whole socks response.</p>
- </li>
-
- <li>
- <p>In chat(), do not bother to generate a client request in case
- of direct CONNECT requests. It will not be used anyway.</p>
+ <p>Added experimental https inspection support which allows to filter https traffic. To enable it, install
+ MbedTLS and configure with --with-mbedtls, or install OpenSSL or LibreSSL and configure with
+ --with-openssl. Afterwards configure the directives in section 7 of the config file and enable the
+ +https-inspection action. Initial MbedTLS-based code contributed by Vaclav Svec, initial OpenSSL support
+ contributed by Maxim Antonov. With help from Nedzad Hrnjica and Ho+ Ho+ Ho+. Integration and improvements
+ sponsored by Robert Klemme.</p>
</li>
-
<li>
- <p>Reduce server_last_modified()'s stack size.</p>
+ <p>pcrs: Request JIT compilation if it's supported and the filter isn't dynamic. This can speed up
+ filtering.</p>
</li>
-
<li>
- <p>Shorten get_http_time() by using strftime().</p>
+ <p>Added support for Brotli decompression. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Constify the known_http_methods pointers in
- unknown_method().</p>
+ <p>Added FEATURE_EXTENDED_STATISTICS to gather statistics for block reasons and filter executions. To
+ enable it, configure with --enable-extended-statistics and visit http://config.privoxy.org/show-status.
+ Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Constify the time_formats pointers in parse_header_time().</p>
+ <p>Use the IP_FREEBIND socket option, if defined. This allows Privoxy to bind to not-yet assigned IP
+ addresses which is useful in failover environments. Patch by Sam Varshavchik.</p>
</li>
-
<li>
- <p>Constify the formerly_valid_actions pointers in
- action_used_to_be_valid().</p>
+ <p>Allow to use extended host patterns and vanilla host patterns at the same time by prefixing extended
+ host patterns with "PCRE-HOST-PATTERN:". To enable this, configure with --enable-pcre-host-patterns.
+ Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Introduce a GNUMakefile MAN_PAGE variable that defaults to
- privoxy.1. The Debian package uses section 8 for the man page and
- this should simplify the patch.</p>
+ <p>Added "Cross-origin resource sharing" (CORS) support. This allows to access Privoxy's CGI interface via
+ JavaScript from another domain (white-listed with the new cors-allowed-origin directive). Based on a patch
+ by Nedzad Hrnjica. Sponsored by: Robert Klemme.</p>
</li>
-
<li>
- <p>Deduplicate the INADDR_NONE definition for Solaris by moving
- it to jbsockets.h</p>
+ <p>Add SOCKS5 username/password support. Based on a patch by Sam, improved by Ivan Romanov. Closes
+ Patch#141 and solves TODO#105.</p>
</li>
-
<li>
- <p>In block_url(), ditch the obsolete workaround for ancient
- Netscape versions that supposedly couldn't properly deal with
- status code 403.</p>
+ <p>Bump the maximum number of action and filter files to 100 each. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Remove a useless NULL pointer check in load_trustfile().</p>
+ <p>Fixed handling of filters with "split-large-forms 1" when using the CGI editor. Reported by withoutname
+ in #921.</p>
</li>
-
<li>
- <p>Remove two useless NULL pointer checks in
- load_one_re_filterfile().</p>
+ <p>Better detect a mismatch of connection details when figuring out whether or not a connection can be
+ reused.</p>
</li>
-
<li>
- <p>Change url_code_map[] from an array of pointers to an array of
- arrays It removes an unnecessary layer of indirection and on
- 64bit system reduces the size of the binary a bit.</p>
+ <p>Don't send a "Connection failure" message instead of the "DNS failure" message. Sponsored by: Robert
+ Klemme</p>
</li>
-
<li>
- <p>Fix various typos. Fixes taken from Debian's 29_typos.dpatch
- by Roland Rosenfeld.</p>
+ <p>Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted requests were only logged with
+ LOG_LEVEL_REQUEST when they weren't crunched (in which case they were logged with LOG_LEVEL_CRUNCH). This
+ was documented behaviour, but logging all requests seems more useful.</p>
</li>
-
<li>
- <p>Add a dok-tidy GNUMakefile target to clean up the messy HTML
- generated by the other dok targets.</p>
+ <p>Fixed locking around localtime() and gmtime().</p>
</li>
-
<li>
- <p>GNUisms in the GNUMakefile have been removed.</p>
+ <p>Removed OS/2 support. We haven't provided OS/2 packages in years, it complicated the code and it
+ depended on a fallback snprintf() implementation which is GPLv2 only.</p>
</li>
-
<li>
- <p>Change the HTTP version in static responses to 1.1</p>
+ <p>Remove the fallback snprintf() implementation Now that OS/2 support is gone we no longer need it.</p>
</li>
-
<li>
- <p>Synced config.sub and config.guess with upstream
- 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.</p>
+ <p>Fixed a bunch of format specifiers log messages.</p>
</li>
-
<li>
- <p>Add a dedicated function to parse the values of toggles.
- Reduces duplicated code in load_config() and provides better
- error handling. Invalid or missing toggle values are now a fatal
- error instead of being silently ignored.</p>
+ <p>Added a missing apostrophe in the 'More Privoxy' menu.</p>
</li>
-
<li>
- <p>Terminate HTML lines in static error messages with \n instead
- of \r\n.</p>
+ <p>Explicitly prevent use of FEATURE_CONNECTION_SHARING without FEATURE_CONNECTION_KEEP_ALIVE. It makes no
+ sense and does not compile anyway. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Simplify cgi_error_unknown() a bit.</p>
+ <p>Fix build without FEATURE_CONNECTION_KEEP_ALIVE. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>In LogPutString(), don't bother looking at pszText when not
- actually logging anything.</p>
+ <p>Downgrade the 'Graceful termination requested' message to LOG_LEVEL_INFO as it isn't an error. Sponsored
+ by: Robert Klemme</p>
</li>
-
<li>
- <p>Change ssplit()'s fourth parameter from int to size_t. Fixes a
- clang complaint.</p>
+ <p>decompress_iob(): Downgrade the no-content message to LOG_LEVEL_RE_FILTER While at it, fix a typo in a
+ comment. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Add a warning that the statistics currently can't be trusted.
- Mention Privoxy-Log-Parser's --statistics option as an
- alternative for the time being.</p>
+ <p>Fixed a couple of cppcheck warnings.</p>
</li>
-
<li>
- <p>In rfc2553_connect_to(), start setting cgi->error_message
- on error.</p>
+ <p>Rename LOG_LEVEL_GPC to LOG_LEVEL_REQUEST. Only the shadow knows what "GPC" is supposed to stand
+ for.</p>
</li>
-
<li>
- <p>Change the expected status code returned for http://p.p/die
- depending on whether or not FEATURE_GRACEFUL_TERMINATION is
- available.</p>
+ <p>Remove SourceForge references in copyright headers.</p>
</li>
-
<li>
- <p>In cgi_die(), mark the client connection for closing. If the
- client will fetch the style sheet through another connection it
- gets the main thread out of the accept() state and should thus
- trigger the actual shutdown.</p>
+ <p>Upgrade a bunch of links to the homepage to https://.</p>
</li>
-
<li>
- <p>Add a proper CGI message for cgi_die().</p>
+ <p>Add 'no-brotli-accepted' filter which prevents the use of Brotli compression.</p>
</li>
-
<li>
- <p>Don't enforce a logical line length limit in
- read_config_line().</p>
+ <p>Changed license for pcrs to GPLv2+ after getting the permission from Andreas. This allows to
+ redistribute Privoxy under the GPLv3 which is required when linking to future mbedTLS versions which are
+ expected to be licensed under the Apache 2.0 license only.</p>
</li>
-
<li>
- <p>Slightly refactor server_last_modified() to remove useless
- gmtime*() calls.</p>
+ <p>Updated a bunch of tests that have to expect status code 403 now after r1.168/070e904afa5.</p>
</li>
-
<li>
- <p>In get_content_type(), also recognize '.jpeg' as JPEG
- extension.</p>
+ <p>Lowercase the host name in the request line.</p>
</li>
-
<li>
- <p>Add '.png' to the list of recognized file extensions in
- get_content_type().</p>
- </li>
-
- <li>
- <p>In block_url(), consistently use the block reason "Request
- blocked by Privoxy" In two places the reason was "Request for
- blocked URL" which hides the fact that the request got blocked by
- Privoxy and isn't necessarily correct as the block may be due to
- tags.</p>
- </li>
-
- <li>
- <p>In listen_loop(), reload the configuration files after
- accepting a new connection instead of before. Previously the
- first connection that arrived after a configuration change would
- still be handled with the old configuration.</p>
- </li>
-
- <li>
- <p>In chat()'s receive-data loop, skip a client socket check if
- the socket will be written to right away anyway. This can
- increase the transfer speed for unfiltered content on fast
- network connections.</p>
- </li>
-
- <li>
- <p>The socket timeout is used for SOCKS negotiations as well
- which previously couldn't timeout.</p>
- </li>
-
- <li>
- <p>Don't keep the client connection alive if any configuration
- file changed since the time the connection came in. This is
- closer to Privoxy's behaviour before keep-alive support for
- client connection has been added and also less confusing in
- general.</p>
- </li>
-
- <li>
- <p>Treat all Content-Type header values containing the pattern
- 'script' as a sign of text. Reported by pribog in #3134970.</p>
+ <p>Only set SOURCE_DATE_EPOCH if it's not already set so distributions can overwrite it through the
+ environment.</p>
</li>
</ul>
</li>
-
<li>
- <p>Action file improvements:</p>
-
+ <p>Documentation changes:</p>
<ul>
<li>
- <p>Moved the site-specific block pattern section below the one
- for the generic patterns so for requests that are matched in
- both, the block reason for the domain is shown which is usually
- more useful than showing the one for the generic pattern.</p>
- </li>
-
- <li>
- <p>Remove -prevent-compression from the fragile alias. It's no
- longer used anywhere by default and isn't known to break stuff
- anyway.</p>
+ <p>Explain that Privoxy has to be distributed under the GPLv3 (or later) when linked with an MbedTLS
+ version that is licensed under the Apache 2.0 license.</p>
</li>
-
<li>
- <p>Add a (disabled) section to block various Facebook tracking
- URLs. Reported by Dan Stahlke in #3421764.</p>
+ <p>Import the GNU GPLv3 and include it the user manual.</p>
</li>
-
<li>
- <p>Add a (disabled) section to rewrite and redirect
- click-tracking URLs used on news.google.com. Reported by Dan
- Stahlke in #3421755.</p>
+ <p>Clarify FEATURE_FORCE_LOAD's description. It allows to bypass blocking not filtering and only does it if
+ blocks aren't enforced. Reported by: Robert Klemme</p>
</li>
-
<li>
- <p>Unblock linuxcounter.net/. Reported by Dan Stahlke in
- #3422612.</p>
+ <p>FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors As of 2021 they no longer handle
+ donations for foreign organisations due to lack of resources.</p>

- Suggested by dg1727 in #3423782.</p>
+ <p>Change the suggested default-server-timeout to 5 to match the suggested keep-alive-timeout. Otherwise

- the filter or tagger, but don't claim it's a filter when it could
- be a tagger.</p>

- <p>In connection_destination_matches(), improve two log messages
- to help understand why the destinations don't match.</p>
+ <p>Change two block reasons that previously were the same. Sponsored by: Robert Klemme</p>

- configuration file change.</p>
- </li>
-
- <li>
- <p>Let mark_server_socket_tainted() always mark the server socket
- tainted, just don't talk about it in cases where it has no
- effect. It doesn't change Privoxy's behaviour, but makes
- understanding the log file easier.</p>
+ <p>Updated the location of the development version of default.action.master.</p>

</ul>
</li>
-
<li>
- <p>configure:</p>

+ the request is invalid.</p>
</li>
-
<li>
- <p>Rename the --disable-acl-files switch to

</li>
-
<li>
- <p>Added tests for missing socks4 and socks4a forwarders.</p>
+ <p>Generate statistics if the log only contains LOG_LEVEL_CLF messages so it can be used with vanilla

</li>

<li>
- <p>The --privoxy-address option now works with IPv6 addresses

</li>
-
<li>
- <p>Disable the range-requests tagger for tests that break if it's
- enabled.</p>
+ <p>Let the statistics include the size of the content Privoxy transferred excluding HTTP headers.</p>
</li>
-
<li>
- <p>Log messages use the ISO 8601 date format %Y-%m-%d.</p>
+ <p>Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST. It's no longer
+ necessary to count both LOG_LEVEL_REQUEST and LOG_LEVEL_CRUNCH messages to get the total number of
+ requests.</p>
</li>
-
<li>
- <p>Fix spelling in two error messages.</p>
+ <p>Leverage the LOG_LEVEL_CLF message to gather statistics that where previously taken from
+ LOG_LEVEL_HEADER lines. This results in less confusing results if https inspection is enabled in which case
+ there are two LOG_LEVEL_HEADER lines with request lines. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>In the --help output, include a list of supported tests and

</li>
-
<li>
