-ChangeLog for Privoxy 3.0.34
+ChangeLog for Privoxy 4.0.0
--------------------------------------------------------------------
- Bug fixes:
- - 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.
+ - Add missing client-body-tagger data to the action_type_info[] struct
+ so lookups based on the action index work correctly again.
+ Prevents assertion failures or segfaults when trying to edit
+ an action file with the CGI editor.
+ The type of failure depended on whether or not assertions
+ were enabled and on whether or not Privoxy had been compiled
+ with FEATURE_EXTERNAL_FILTERS.
+ Regression introduced in Privoxy 3.0.34.
+ Patch submitted by Aaron Li in #940.
+ - Bump MAX_FILTER_TYPES which should have been done in d128e6aa4
+ when introducing the client-body-tagger{} action.
+ Prevents an assertion in cgi_edit_actions_for_url() from triggering
+ after e32d03e0 when using the CGI editor with assertions enabled.
+ - is_untrusted_url(): Search the encrypted headers for the Referer
+ when the client is using https and https inspection is enabled.
+ Fixes the trust mechanism for https requests.
+ Reported by Laurent Caumont in #1767.
+ - GNUMakefile.in: Let the install target work if no group is specified.
+ - GNUMakefile.in: Set GROUP_T when installing configuration files as root
+ and there is no privoxy user available so the install target doesn't
+ fail. Patch by Fabrice Fontaine.
+ - GNUmakefile.in: Don't exit if configuration files are installed as root
+ as this can be considered acceptable when cross-compiling
+ Privoxy inside an autobuilder with only a root user.
+ Patch by Fabrice Fontaine.
+ - configure.in: Fix argument types in gmtime_r() and localtime_r() probes.
+ Otherwise these probes always fail with stricter compilers
+ even if there is C library support for these functions.
+ Patch submitted by Florian Weimer in SF#149.
+ - Fix socks4 and socks4a support under glibc's source fortification.
+ With glibc's source fortification, gcc offers the compilation warning
+ resulting in a runtime abort() when using a socks4 or socks4a upstream proxy.
+ Despite the warning, the strlcpy() call in question is fine: gcc
+ misidentifies the size of the destination buffer, estimating to hold
+ only a single char while in fact the buffer stretches beyond the end of
+ the struct socks_op.
+ The issue was originally reported in the NixOS issue tracker at
+ https://github.com/NixOS/nixpkgs/issues/265654
+ prompted by an upgrade of glibc from 2.37-39 to 2.38-0.
+ Patch submitted by Ingo Blechschmid, joint work with
+ @esclear and @richi235.
- General improvements:
- - 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.
+ - Allow to use wolfSSL for https inspection.
+ wolfSSL supports TLS 1.3 and can be significantly faster than
+ mbedTLS. Mainly tested on ElectroBSD amd64 where it can compete
+ with OpenSSL and LibreSSL:
+ https://www.fabiankeil.de/gehacktes/privoxy-tls-benchmarks/
+ To enable the support, install wolfSSL and run ./configure
+ with the --with-wolfssl option.
+ Sponsored by Privoxy project funds collected at SPI.
+ - Add an test framework that leverages the curl test suite.
+ Sponsored by Privoxy project funds collected at SPI.
+ - Add pcre2 support. Closes bug #935.
+ Initial patch submitted by Gagan Sidhu.
+ - Use SHA256 as hash algorithm for the certificate and key file names
+ instead of MD5. The known MD5 vulnerabilities shouldn't matter for
+ Privoxy's use case but it doesn't hurt to use a hash algorithm that
+ isn't deprecated.
+ Sponsored by: Robert Klemme
+ - Add support for mbedTLS 3.x. This removes a sanity check
+ (whether issuer key and issuer certificate match) that seems
+ overly cautious and fails to compile with mbedTLS 3.x as the
+ struct members are private. We don't have an equivalent check
+ in the OpenSSL or wolfSSL code either.
+ - Factor out newer_privoxy_version_required() and improve the logic
+ Previously 3.0.11 was considered newer than 4.0.0.
+ - init_error_log(): Include the reason for failures to open the log file.
+ - create_client_ssl_connection(): Don't keep the certificate lock
+ longer than necessary.
+ - Add periods to a bunch of log messages.
+ - normalize_lws(): Only log the 'Reducing whitespace ...' message
+ once per header
+ - log_error() Win32: Only call LogShowActivity() for debug level
+ LOG_LEVEL_REQUEST. As of b94bbe62a950, which was part of Privoxy 3.0.29,
+ LOG_LEVEL_REQUEST is used for all requests including crunched ones.
+ Previously LogShowActivity() was called twice for crunched
+ requests, (presumably) resulting in an aborted animation.
+ - Remove ./ prefix from tarball-dist files.
+ - create_client_ssl_connection(): Make it more obvious from an
+ error message that a function failed.
+ - Use stringify() instead of section_target() and remove section_target().
+ Like the XXX comment suggested this could be done my moving the hash
+ into the templates which seems preferable anyway.
+ - Prevent some compiler warnings.
+ - parse_numeric_value(): Expect a base-ten number.
+ - windows/MYconfigure: Have gcc diagnostics in color.

- 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.
+ - Highlight 'Couldn't deliver the error message for [...]'.
+ - Highlight 'Failed to accept() incoming connection: Software caused connection abort'.
+ - Highlight 'Keeping chunk offset at 0 despite flushing 31 bytes.'.
+ - Highlight 'Not shutting down client connection on socket 8. The socket is no longer alive.'.
+ - Bump version to 0.9.6.
+
+- Privoxy-Regression-Test.pl:
+ - Let the --min-level option increase the --max-level
+ if the latter is smaller than the former.
+ - Add --curl option to use a non-default curl binary.
+ - Bump version to 0.7.5.

- 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).
+ - Bump BROWSER_VERSION and BROWSER_REVISION to match Firefox ESR 128.
+ - Bump version to 1.2.6.
