<para>
- Fixed a memory leak when rejecting client connections due to
- the socket limit being reached (CID 66382). This affected
- Privoxy 3.0.21 when compiled with IPv6 support (on most
- platforms this is the default).
+ 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.
</para>
</listitem>
<listitem>
<para>
- Fixed an immediate-use-after-free bug (CID 66394) and two
- additional unconfirmed use-after-free complaints made by
- Coverity scan (CID 66391, CID 66376).
+ 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.
</para>
</listitem>
<listitem>
<para>
- Actually show the FORCE_PREFIX value on the show-status page.
+ 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.
</para>
</listitem>
<listitem>
<para>
- Properly deal with Keep-Alive headers with timeout= parameters
- If the timeout still can't be parsed, use the configured
- timeout instead of preventing the client from keeping the
- connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
+ 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.
</para>
</listitem>
<listitem>
<para>
- Not using any filter files no longer results in warning messages
- unless an action file is referencing header taggers or filters.
- Reported by Stefan Kurtz in #3614835.
+ can_filter_request_body(): Fix a log message that contained a spurious u.
</para>
</listitem>
<listitem>
<para>
- Fixed a bug that prevented Privoxy from reusing some reusable
- connections. Two bit masks with different purpose unintentionally
- shared the same bit.
+ 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.
</para>
</listitem>
<listitem>
<para>
- A couple of additional bugs were discovered by Coverity Scan.
- The fixes that are not expected to affect users are not explicitly
- mentioned here, for details please have a look at the CVS logs.
+ 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.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ socks5_connect(): Add support for target hosts specified as IPv4 address
+ Previously the IP address was sent as domain.
</para>
</listitem>
</itemizedlist>
<itemizedlist>
<listitem>
<para>
- Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG.
- They apply if no matching tag is found after parsing client or
- server headers.
+ Add a client-body-tagger action which creates tags based on
+ the content of the request body.
+ Sponsored by: Robert Klemme.
</para>
</listitem>
<listitem>
<para>
- Add support for external filters which allow to process the
- response body with a script or program written in any language
- the platform supports. External filters are enabled with
- +external-filter{} after they have been defined in one of the
- filter files with a header line starting with "EXTERNAL-FILTER:".
- External filter support is experimental, not compiled by default
- and known not to work on all platforms.
+ 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.
</para>
</listitem>
<listitem>
<para>
- Add support for the 'PATCH' method as defined in RFC5789.
+ Add periods to a couple of log messages.
</para>
</listitem>
<listitem>
<para>
- Reject requests with unsupported Expect header values.
- Fixes a couple of Co-Advisor tests.
+ accept_connection(): Add missing space to a log message.
</para>
</listitem>
<listitem>
<para>
- Normalize the HTTP-version in forwarded requests and responses.
- This is an explicit RFC 2616 MUST and RFC 7230 mandates that
- intermediaries send their own HTTP-version in forwarded
- messages.
+ Initialize ca-related defaults with strdup_or_die() so errors
+ aren't silently ignored.
</para>
</listitem>
<listitem>
<para>
- Server 'Keep-Alive' headers are no longer forwarded. From a user's
- point of view it doesn't really matter, but RFC 2616 (obsolete)
- mandates that the header is removed and this fixes a Co-Advisor
- complaint.
+ make_path: Use malloc_or_die() in cases where allocation errors
+ were already fatal anyway.
</para>
</listitem>
<listitem>
<para>
- Change declared template file encoding to UTF-8. The templates
- already used a subset of UTF-8 anyway and changing the declaration
- allows to properly display UTF-8 characters used in the action files.
- This change may require existing action files with ISO-8859-1
- characters that aren't valid UTF-8 to be converted to UTF-8.
- Requested by Sam Chen in #582.
+ handle_established_connection(): Improve an error message slightly.
</para>
</listitem>
<listitem>
<para>
- Do not pass rejected keep-alive timeouts to the server. It might
- not have caused any problems (we know of), but doing the right
- thing shouldn't hurt either.
+ receive_client_request(): Reject https URLs without CONNECT request.
</para>
</listitem>
<listitem>
<para>
- Let log_error() use its own buffer size #define to make changing
- the log buffer size slightly less inconvenient.
+ 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.
</para>
</listitem>
<listitem>
<para>
- Turned single-threaded into a "proper" toggle directive with arguments.
+ Add read_socks_reply() and start using it in socks5_connect()
+ to apply the socket timeout more consistently.
</para>
</listitem>
<listitem>
<para>
- CGI templates no longer enforce new windows for some links.
+ socks5_connect(): Deal with domain names in the socks reply
</para>
</listitem>
<listitem>
<para>
- Remove an undocumented workaround ('HOST' header removal) for
- an Apple iTunes bug that according to #729900 got fixed in 2003.
+ Add a filter for bundeswehr.de that hides the cookie and
+ privacy info banner.

+ While at it, add a comment with an example log line.
