Update Changelog

  • Property mode set to 100644
File size: 16.4 KB
1** Version 0.12.0 (UNRELEASED)
3- Remove insecure algorithms that are still included in the GnuTLS
4  priority set "NORMAL" from the default priorities: plain RSA key
5  exchange, TLS 1.0, TLS 1.1
7- Share server instances for tests where reasonably possible with the
8  same server configuration. Starting/stopping server instances is the
9  slowest part of the tests, so this is a nice performance
10  improvement. The Automake test harness now reports fewer tests, but
11  some include a lot more client connections and requests to keep
12  coverage at least as good as before.
14- Some minor cleanup of tests and logging infrastructure.
16** Version 0.11.0 (2020-06-27)
18- Change default for GnuTLSOCSPCheckNonce to "off", and send OCSP
19  nonces only if it has been enabled. The reason for this change is
20  that in practice most public CAs do not support OCSP nonces, which
21  is permitted by both RFC 6960 and the CA/Browser Forum baseline
22  requirements (as of version 1.6.9). In this situation enforcing
23  correct nonces by default makes the automatic OCSP stapling support
24  mostly useless.
26- Add a test for correct nonce handling with "GnuTLSOCSPCheckNonce
27  on", thanks to Krista Karppinen for that and a rewrite of the OCSP
28  responder script in Python!
30- Support session resumption using session tickets for proxy
31  connections (TLS 1.3 connections only). Requires a suitable
32  GnuTLSCache configuration.
34- Disable session tickets by default. The GnuTLS built-in key rotation
35  for session tickets never actually changes the primary key, just
36  derives keys from it, so it does not provide forward secrecy in case
37  an attacker learns the primary key (by gaining access to server
38  RAM). A reload of the server is enough to generate a new key, so
39  consider enabling session tickets and reloading the server every few
40  hours, at least until a forward-secret rotation can be implemented.
42- Fix a bug that mostly prevented searching ServerAliases when
43  selecting the virtual host from SNI.
45- Add ./configure option to disable building PDF documentation
47- Deprecate SRP and disable it by default.
49- Add support for building coverage reports using clang's source-based
50  code coverage.
52- Make ./configure check if both [::1] and are available,
53  disable either if not. This makes the build work out-of-the-box in
54  Docker containers, which by default use IPv4 only.
56** Version 0.10.0 (2020-02-03)
58- Added support for stapling multiple OCSP responses (TLS 1.3
59  only). mod_gnutls will staple for as many consecutive certificates
60  in the certificate chain as possible.
62- Added support for TLS 1.3 post-handshake authentication, used if TLS
63  client authentication is required only for some resources on the
64  server. Rehandshake (for older TLS versions) is not supported, the
65  existing but broken code has been removed.
67- The test infrastructure has been mostly rewritten in Python, note
68  the new dependencies (Python 3, Pyyaml). Tests can run multiple TLS
69  connections and HTTP(S) requests as well as custom hooks now, see
70  test/ for details.
72- Server certificates are checked for the must-staple TLS feature
73  extension, stapling must be enabled if it is present.
75- Compatibility fix for GnuTLS 3.6.11 in the test suite: Handle
76  peer certificate type in TLS session information strings.
78- The test system will automatically detect if it needs to load
79  critical modules (e.g. mod_logio) that are built-in with the Debian
80  packages. This makes the tests work on Fedora without modifications,
81  and likely on similar distributions too.
83- Tests can optionally run with Valgrind for the primary HTTPD
84  instance by running ./configure with --enable-valgrind-test, see
85  test/ for details.
87- Known issue: When using MSVA client certificate validation the
88  Valgrind tests indicate memory leaks from libcurl, which is used by
89  libmsv to send requests to the MSVA. For details see the bug report:
92** Version 0.9.1 (2019-11-29)
93- Fix possible segfault (NULL pointer dereference) on failed TLS
94  handshake. Calling ssl_var_lookup() after a failed handshake could
95  lead to GnuTLS session information functions being called on a NULL
96  session pointer, leading to segfault.
97- Remove URLs from expected error responses in the test suite. Apache
98  HTTPD removed request URLs from canned error messages to prevent
99  misleading text/links being displayed via crafted links
100  (CVE-2019-10092). Adjust the expected error responses in our tests
101  so they can pass again.
102- Test suite: Ignore "Content-Length" header of responses. Thanks to
103  Krista Karppinen!
104- Add a section about module dependencies on socache to the handbook
105- Restructure the manpage build and move it to section 5 (config
106  files)
107- Test suite: Restructure certificate directories
109** Version 0.9.0 (2019-01-23)
110- Security fix: Refuse to send or receive any data over a failed TLS
111  connection (commit 72b669eae8c45dda1850e8e5b30a97c918357b51). The
112  previous behavior could lead to requests on reverse proxy TLS
113  connections being sent in plain text, and might have allowed faking
114  requests in plain text.
115- Security fix: Reject HTTP requests if they try to access virtual
116  hosts that do not match their TLS connections (commit
117  de3fad3c12f53cdbf082ad675e4b10f521a02811). Additionally check if SNI
118  and Host header match. Thanks to Krista Karppinen for contributing
119  tests!
120- OCSP stapling is now enabled by default, if possible. OCSP responses
121  are updated regularly and stored in a cache separate from the
122  session cache. The OCSP cache uses mod_socache_shmcb by default
123  (if the module is loaded, no other configuration required).
124- Session tickets are now enabled by default if using GnuTLS 3.6.4 or
125  newer. GnuTLS 3.6.4 introduced automatic rotation for the used key,
126  and TLS 1.3 takes care of other reasons not to use tickets while
127  requiring them for session resumption. Note that there is currently
128  no mechanism to synchronize ticket keys across a cluster of servers.
129- The internal cache implementation has been replaced with
130  mod_socache. Users may need to update their GnuTLSCache settings and
131  load the appropriate socache modules.
132- ALPN (required for HTTP/2) now works correctly with different
133  "Protocols" directives between virtual hosts if building with GnuTLS
134  3.6.3 or newer. Older versions require identical "Protocols"
135  directives for overlapping virtual hosts. Thanks to Vincent Tamet
136  for the bug report!
137- ALPN is now supported for proxy connections, making HTTP/2 proxy
138  connections using mod_proxy_http2 possible.
139- GnuTLSPriorities is optional now and defaults to "NORMAL" if
140  missing. The same applies to GnuTLSProxyPriorities (if TLS proxy is
141  enabled).
142- The manual is now built as a manual page, too, if pandoc is
143  available.
144- OpenPGP support has been removed.
145- Don't require pem2openpgp for tests when building without MSVA
146  support.
148** Version 0.8.4 (2018-04-13)
149- Support Apache HTTPD 2.4.33 API for proxy TLS connections
150- Support TLS for HTTP/2 connections with mod_http2
151- Fix configuration of OCSP stapling callback
153** Version 0.8.3 (2017-10-20)
154- Use GnuTLS' default DH parameters by default
155- Handle long Server Name Indication data and gracefully ignore
156  unknown SNI types
157- Send SNI for proxy connections
158- Deprecate OpenPGP support like GnuTLS did (will be removed
159  completely in a future release)
160- Do not announce session ticket support for proxy connections
161- Minor documentation updates (SSL_CLIENT_I_DN, reference for SNI)
162- Test suite: Simplify handling of proxy backend servers and OCSP
163  responders
164- Test suite: stability/compatibility fixes
166** Version 0.8.2 (2017-01-08)
167- Test suite: Ensure CRLF line ends in HTTP headers
168- Test suite, gen_ocsp_index.c: Handle serial as fixed order byte array
170** Version 0.8.1 (2016-12-20)
171- Bugfix: Use APR_SIZE_T_FMT for portable apr_size_t formatting
173** Version 0.8.0 (2016-12-11)
174- New: Support for OCSP stapling
175- Bugfix: Access to DBM cache is locked using global mutex
176  "gnutls-cache"
177- Bugfix: GnuTLSSessionTickets is now disabled by default as described
178  in the handbook
179- Fixed memory leak while checking proxy backend certificate
180- Fixed memory leaks in post_config
181- Safely delete session ticket key (requires GnuTLS >= 3.4)
182- Improved error handling in post_config hook
183- Various handbook updates
184- Internal API documentation can be generated using Doxygen
185- Unused code has been removed (conditionals for GnuTLS 2.x and Apache
186  versions before 2.2, internal Lua bytecode structure last used in
187  2011).
188- Test suite: Fixed locking for access to the PGP keyring of the test
189  certificate authority
190- mod_gnutls can be built using Clang (unsupported)
192** Version 0.7.5 (2016-05-28)
193- Sunil Mohan Adapa reported retry loops during session shutdown in
194  cleanup_gnutls_session() due to gnutls_bye() incorrectly returning
195  GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN. Setting the GnuTLS session
196  errno in mgs_transport_write() fixes the problem.
197- Import Daniel Kahn Gillmor's patches for GnuPG v2 support from the
198  Debian package.
199- Build system improvements that allow VPATH builds and get "make
200  distcheck" to work
202** Version 0.7.4 (2016-04-13)
203- Support SoftHSM 2 for PKCS #11 testing
204- Increase verbosity of test logs
206** Version 0.7.3 (2016-01-12)
207- Update test suite for compatibility with GnuTLS 3.4, which has
208  stricter key usage checks and priorities than 3.3.
209- Write non-HTML output to mod_status reports if AP_STATUS_SHORT is
210  set (mod_status sets it for requests with the "auto" parameter, e.g.
211  https://localhost/server-status?auto).
212- Register "ssl_is_https" function so the special mod_rewrite variable
213  %{HTTPS} works correctly with mod_gnutls. The new test case for this
214  requires Wget or curl. Fixes Debian bug #514005.
215- Test suite servers listen on IPv4 *and* IPv6 loopback addresses by
216  default (other addresses configurable), which should fix failures
217  due to localhost randomly resolving to either on some distributions.
218- Isolate tests using network namespaces, if possible. This avoids
219  port conflicts with other test cases (so they can run in parallel)
220  and host services.
221- Support for local Apache drop-in config files in the test suite
222  (e.g. to load additional modules needed on Fedora).
223- Try to use markdown to build HTML documentation if pandoc is not
224  available.
225- Disable use of flock if it is unavailable or does not support
226  timeouts (the latter caused the build to fail on Debian Hurd).
227- New test: Disable TLS 1.0 (regression test for Debian bug #754960).
229** Version 0.7.2 (2015-11-21)
230- Bugfix: Non-blocking reads in the input filter could lead to a busy
231  wait in the gnutls_io_input_read function, causing high load on
232  Keep-Alive connections waiting for data, until either more data
233  could be received or the connection was closed. The fix is to pass
234  EAGAIN/EINTR results up to the input filter so they can be handled
235  properly.
236- Close TLS session if the input filter receives EOF (mostly relevant
237  for proper termination of proxy connections).
238- Remove dependency on APR Memcache, which is replaced by the newer
239  version included in the APR Utility Library (libaprutil).
240- Remove dependency on bc. It was used for floating point arithmetic
241  in the test suite, the calculations have been changed to use
242  integers and pure bash code.
244** Version 0.7.1 (2015-10-18)
245- Improved handling of PKCS #11 modules: mod_gnutls now loads either
246  modules specified using GnuTLSP11Module, or the system defaults, but
247  not both. Thanks to Nikos Mavrogiannopoulos for the report and
248  initial patch!
249- Initialize variables to safe defaults during client certificate
250  verification. Certain error code paths did not set them, but they
251  should never be hit due to config validation. This adds another line
252  of defense.
253- Enable C99 support via autoconf
254- Test suite improvements. Most importantly, automake now handles
255  environment setup without any external make calls. Rules to build
256  the certificates are included from the old test makefile. Note that
257  the dependency on GNU make is not new (the test makefile always used
258  GNU make syntax), it just wasn't listed explicitly.
260** Version 0.7 (2015-07-12)
261- Security fix for TLS client authentication (CVE-2015-2091)
262- Bug fixes that enable support for reverse proxy operation
263- Various test suite improvements. Tests are configured through autoconf,
264  so the test suite now works for builds without Monkeysphere support.
265- Add support for TLS connections to back end servers when operating as a
266  reverse proxy (X.509 authentication only at the moment).
267- PKCS #11 support for server keys and certificates
268- Use strict compiler arguments by default (-Wall -Werror -Wextra)
269- Allow limiting the size of certificates exported as SSL_SERVER_CERT
270  and SSL_CLIENT_CERT through the GnuTLSExportCertificates directive
272** Version 0.6 (2014-02-17)
273- Generating DH Params instead of using static ones.
274- Now considering ServerAlias Directives.
275- Major Legacy Code Cleanup.
276- html and pdf and manual documentation generated from markdown sources
277- support monkeysphere validation agent (MSVA) client-certificate verification
278- wider test suite
279- GnuTLSExportCertificates off by default
281** Version 0.5.10 (2011-07-12)
282- Patched a bug responsible for excessive memory consumption by mod_gnutls.
283- Support for proxying from SSL to plain HTTP was added (ie. proxy termination).
285** Version 0.5.9 (2010-09-24)
286- GnuTLSCache none is now an allowed option.
287- Corrected behavior in Keep-Alive connections (do not
288  terminate the connection prematurely)
289- The GnuTLSCache variable now can be given the specific
290  option "gdbm" instead of "dbm". "dbm" will use the berkeley
291  db type of libapr while gdbm will force gdbm to be used.
292  sdbm is no longer being used due to serious limitations.
294** Version 0.5.8 (2010-08-18)
295- Session tickets are enabled by default.
296- Fixes some segmentation faults noticed in some
297  configurations.
299** Version 0.5.7 (2010-07-01)
300- Force usage of SDBM. For some reason the default in
301  my system had issues after reaching a limit of entries.
302  SDBM seems stable so force it.
303- Optimizations in session caching.
304- Added support for session tickets. This allows a
305  server to avoid using a session cache and still support
306  session resumption. This is at the cost of transporting
307  session data during handshake. New option
308  GnuTLSSessionTickets [on|off]
309- Depend on gnutls 2.10.0 to force support for safe
310  renegotiation.
312** Version 0.5.6 (2010-03-24)
313- Corrected issue with firefox and long POST data (by
314  handling EINTR and EAGAIN errors in read).
315- Added support for chained client certificates
316- Corrected more issues related to double frees
319** Version 0.5.5 (2009-06-13)
320- Removed limits on CA certificate loading. Reported by
321  Sander Marechal and Jack Bates.
322- Do not allow sending empty TLS packets even when instructed to.
323  This had the side effect of clients closing connection.
325** Version 0.5.4 (2009-01-04)
326- mod_gnutls.h: modified definition to extern to avoid compilation
327  errors in darwin.
328- Added patch to fix issue with mod_proxy. Investigation and patch by Alain
329  Knaff.
330- libgnutls detection uses pkg-config.
332** Version 0.5.3 (2008-10-16)
333- Corrected bug to allow having an OpenPGP-only web site.
334- Increased Max handshake tries due to interrupted system calls.
336** Version 0.5.2 (2008-06-29)
337- Depend on gnutls 2.4 which has openpgp support in main library.
339** Version 0.5.1 (2008-03-05)
340- Added --disable-srp configure option
341- Better check for memcache (patch by Guillaume Rousse)
342- Corrected possible memory leak in DBM support for resuming sessions.
344** Version 0.5.0-alpha (2008-01-24)
345- Added support for OpenPGP keys. The new directives are:
346  GnuTLSPGPKeyringFile, GnuTLSPGPCertificateFile, GnuTLSPGPKeyFile
348** Version 0.4.2 (2007-12-10)
349- Added support for sending a certificate chain.
350- Corrected bug which did not allow the TLS session cache to be used.
351- Do not allow resuming sessions on different servers.
353** Version 0.4.1 (2007-12-03)
354- Added support for subject alternative names in certificates.
355Only one per certificate is supported.
356- New enviroment variables: SSL_CLIENT_M_VERSION, SSL_CLIENT_S_SAN%,
358- The compatibility mode can now be enabled explicitely with the
359%COMPAT keyword at the GnuTLSPriorities string. It is no longer the default.
360- Check for GnuTLSPriorities directive. This corrects a segfault. Thanks
361to David Hrbáč.
362- Better handling of GnuTLSDHFile and GnuTLSRSAFile.
363- No longer default paths for RSA and DH parameter files.
