Release version 0.10.0

  • Property mode set to 100644
File size: 14.0 KB
1** Version 0.10.0 (2020-02-03)
3- Added support for stapling multiple OCSP responses (TLS 1.3
4  only). mod_gnutls will staple for as many consecutive certificates
5  in the certificate chain as possible.
7- Added support for TLS 1.3 post-handshake authentication, used if TLS
8  client authentication is required only for some resources on the
9  server. Rehandshake (for older TLS versions) is not supported, the
10  existing but broken code has been removed.
12- The test infrastructure has been mostly rewritten in Python, note
13  the new dependencies (Python 3, Pyyaml). Tests can run multiple TLS
14  connections and HTTP(S) requests as well as custom hooks now, see
15  test/ for details.
17- Server certificates are checked for the must-staple TLS feature
18  extension, stapling must be enabled if it is present.
20- Compatibility fix for GnuTLS 3.6.11 in the test suite: Handle
21  peer certificate type in TLS session information strings.
23- The test system will automatically detect if it needs to load
24  critical modules (e.g. mod_logio) that are built-in with the Debian
25  packages. This makes the tests work on Fedora without modifications,
26  and likely on similar distributions too.
28- Tests can optionally run with Valgrind for the primary HTTPD
29  instance by running ./configure with --enable-valgrind-test, see
30  test/ for details.
32- Known issue: When using MSVA client certificate validation the
33  Valgrind tests indicate memory leaks from libcurl, which is used by
34  libmsv to send requests to the MSVA. For details see the bug report:
37** Version 0.9.1 (2019-11-29)
38- Fix possible segfault (NULL pointer dereference) on failed TLS
39  handshake. Calling ssl_var_lookup() after a failed handshake could
40  lead to GnuTLS session information functions being called on a NULL
41  session pointer, leading to segfault.
42- Remove URLs from expected error responses in the test suite. Apache
43  HTTPD removed request URLs from canned error messages to prevent
44  misleading text/links being displayed via crafted links
45  (CVE-2019-10092). Adjust the expected error responses in our tests
46  so they can pass again.
47- Test suite: Ignore "Content-Length" header of responses. Thanks to
48  Krista Karppinen!
49- Add a section about module dependencies on socache to the handbook
50- Restructure the manpage build and move it to section 5 (config
51  files)
52- Test suite: Restructure certificate directories
54** Version 0.9.0 (2019-01-23)
55- Security fix: Refuse to send or receive any data over a failed TLS
56  connection (commit 72b669eae8c45dda1850e8e5b30a97c918357b51). The
57  previous behavior could lead to requests on reverse proxy TLS
58  connections being sent in plain text, and might have allowed faking
59  requests in plain text.
60- Security fix: Reject HTTP requests if they try to access virtual
61  hosts that do not match their TLS connections (commit
62  de3fad3c12f53cdbf082ad675e4b10f521a02811). Additionally check if SNI
63  and Host header match. Thanks to Krista Karppinen for contributing
64  tests!
65- OCSP stapling is now enabled by default, if possible. OCSP responses
66  are updated regularly and stored in a cache separate from the
67  session cache. The OCSP cache uses mod_socache_shmcb by default
68  (if the module is loaded, no other configuration required).
69- Session tickets are now enabled by default if using GnuTLS 3.6.4 or
70  newer. GnuTLS 3.6.4 introduced automatic rotation for the used key,
71  and TLS 1.3 takes care of other reasons not to use tickets while
72  requiring them for session resumption. Note that there is currently
73  no mechanism to synchronize ticket keys across a cluster of servers.
74- The internal cache implementation has been replaced with
75  mod_socache. Users may need to update their GnuTLSCache settings and
76  load the appropriate socache modules.
77- ALPN (required for HTTP/2) now works correctly with different
78  "Protocols" directives between virtual hosts if building with GnuTLS
79  3.6.3 or newer. Older versions require identical "Protocols"
80  directives for overlapping virtual hosts. Thanks to Vincent Tamet
81  for the bug report!
82- ALPN is now supported for proxy connections, making HTTP/2 proxy
83  connections using mod_proxy_http2 possible.
84- GnuTLSPriorities is optional now and defaults to "NORMAL" if
85  missing. The same applies to GnuTLSProxyPriorities (if TLS proxy is
86  enabled).
87- The manual is now built as a manual page, too, if pandoc is
88  available.
89- OpenPGP support has been removed.
90- Don't require pem2openpgp for tests when building without MSVA
91  support.
93** Version 0.8.4 (2018-04-13)
94- Support Apache HTTPD 2.4.33 API for proxy TLS connections
95- Support TLS for HTTP/2 connections with mod_http2
96- Fix configuration of OCSP stapling callback
98** Version 0.8.3 (2017-10-20)
99- Use GnuTLS' default DH parameters by default
100- Handle long Server Name Indication data and gracefully ignore
101  unknown SNI types
102- Send SNI for proxy connections
103- Deprecate OpenPGP support like GnuTLS did (will be removed
104  completely in a future release)
105- Do not announce session ticket support for proxy connections
106- Minor documentation updates (SSL_CLIENT_I_DN, reference for SNI)
107- Test suite: Simplify handling of proxy backend servers and OCSP
108  responders
109- Test suite: stability/compatibility fixes
111** Version 0.8.2 (2017-01-08)
112- Test suite: Ensure CRLF line ends in HTTP headers
113- Test suite, gen_ocsp_index.c: Handle serial as fixed order byte array
115** Version 0.8.1 (2016-12-20)
116- Bugfix: Use APR_SIZE_T_FMT for portable apr_size_t formatting
118** Version 0.8.0 (2016-12-11)
119- New: Support for OCSP stapling
120- Bugfix: Access to DBM cache is locked using global mutex
121  "gnutls-cache"
122- Bugfix: GnuTLSSessionTickets is now disabled by default as described
123  in the handbook
124- Fixed memory leak while checking proxy backend certificate
125- Fixed memory leaks in post_config
126- Safely delete session ticket key (requires GnuTLS >= 3.4)
127- Improved error handling in post_config hook
128- Various handbook updates
129- Internal API documentation can be generated using Doxygen
130- Unused code has been removed (conditionals for GnuTLS 2.x and Apache
131  versions before 2.2, internal Lua bytecode structure last used in
132  2011).
133- Test suite: Fixed locking for access to the PGP keyring of the test
134  certificate authority
135- mod_gnutls can be built using Clang (unsupported)
137** Version 0.7.5 (2016-05-28)
138- Sunil Mohan Adapa reported retry loops during session shutdown in
139  cleanup_gnutls_session() due to gnutls_bye() incorrectly returning
140  GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN. Setting the GnuTLS session
141  errno in mgs_transport_write() fixes the problem.
142- Import Daniel Kahn Gillmor's patches for GnuPG v2 support from the
143  Debian package.
144- Build system improvements that allow VPATH builds and get "make
145  distcheck" to work
147** Version 0.7.4 (2016-04-13)
148- Support SoftHSM 2 for PKCS #11 testing
149- Increase verbosity of test logs
151** Version 0.7.3 (2016-01-12)
152- Update test suite for compatibility with GnuTLS 3.4, which has
153  stricter key usage checks and priorities than 3.3.
154- Write non-HTML output to mod_status reports if AP_STATUS_SHORT is
155  set (mod_status sets it for requests with the "auto" parameter, e.g.
156  https://localhost/server-status?auto).
157- Register "ssl_is_https" function so the special mod_rewrite variable
158  %{HTTPS} works correctly with mod_gnutls. The new test case for this
159  requires Wget or curl. Fixes Debian bug #514005.
160- Test suite servers listen on IPv4 *and* IPv6 loopback addresses by
161  default (other addresses configurable), which should fix failures
162  due to localhost randomly resolving to either on some distributions.
163- Isolate tests using network namespaces, if possible. This avoids
164  port conflicts with other test cases (so they can run in parallel)
165  and host services.
166- Support for local Apache drop-in config files in the test suite
167  (e.g. to load additional modules needed on Fedora).
168- Try to use markdown to build HTML documentation if pandoc is not
169  available.
170- Disable use of flock if it is unavailable or does not support
171  timeouts (the latter caused the build to fail on Debian Hurd).
172- New test: Disable TLS 1.0 (regression test for Debian bug #754960).
174** Version 0.7.2 (2015-11-21)
175- Bugfix: Non-blocking reads in the input filter could lead to a busy
176  wait in the gnutls_io_input_read function, causing high load on
177  Keep-Alive connections waiting for data, until either more data
178  could be received or the connection was closed. The fix is to pass
179  EAGAIN/EINTR results up to the input filter so they can be handled
180  properly.
181- Close TLS session if the input filter receives EOF (mostly relevant
182  for proper termination of proxy connections).
183- Remove dependency on APR Memcache, which is replaced by the newer
184  version included in the APR Utility Library (libaprutil).
185- Remove dependency on bc. It was used for floating point arithmetic
186  in the test suite, the calculations have been changed to use
187  integers and pure bash code.
189** Version 0.7.1 (2015-10-18)
190- Improved handling of PKCS #11 modules: mod_gnutls now loads either
191  modules specified using GnuTLSP11Module, or the system defaults, but
192  not both. Thanks to Nikos Mavrogiannopoulos for the report and
193  initial patch!
194- Initialize variables to safe defaults during client certificate
195  verification. Certain error code paths did not set them, but they
196  should never be hit due to config validation. This adds another line
197  of defense.
198- Enable C99 support via autoconf
199- Test suite improvements. Most importantly, automake now handles
200  environment setup without any external make calls. Rules to build
201  the certificates are included from the old test makefile. Note that
202  the dependency on GNU make is not new (the test makefile always used
203  GNU make syntax), it just wasn't listed explicitly.
205** Version 0.7 (2015-07-12)
206- Security fix for TLS client authentication (CVE-2015-2091)
207- Bug fixes that enable support for reverse proxy operation
208- Various test suite improvements. Tests are configured through autoconf,
209  so the test suite now works for builds without Monkeysphere support.
210- Add support for TLS connections to back end servers when operating as a
211  reverse proxy (X.509 authentication only at the moment).
212- PKCS #11 support for server keys and certificates
213- Use strict compiler arguments by default (-Wall -Werror -Wextra)
214- Allow limiting the size of certificates exported as SSL_SERVER_CERT
215  and SSL_CLIENT_CERT through the GnuTLSExportCertificates directive
217** Version 0.6 (2014-02-17)
218- Generating DH Params instead of using static ones.
219- Now considering ServerAlias Directives.
220- Major Legacy Code Cleanup.
221- html and pdf and manual documentation generated from markdown sources
222- support monkeysphere validation agent (MSVA) client-certificate verification
223- wider test suite
224- GnuTLSExportCertificates off by default
226** Version 0.5.10 (2011-07-12)
227- Patched a bug responsible for excessive memory consumption by mod_gnutls.
228- Support for proxying from SSL to plain HTTP was added (ie. proxy termination).
230** Version 0.5.9 (2010-09-24)
231- GnuTLSCache none is now an allowed option.
232- Corrected behavior in Keep-Alive connections (do not
233  terminate the connection prematurely)
234- The GnuTLSCache variable now can be given the specific
235  option "gdbm" instead of "dbm". "dbm" will use the berkeley
236  db type of libapr while gdbm will force gdbm to be used.
237  sdbm is no longer being used due to serious limitations.
239** Version 0.5.8 (2010-08-18)
240- Session tickets are enabled by default.
241- Fixes some segmentation faults noticed in some
242  configurations.
244** Version 0.5.7 (2010-07-01)
245- Force usage of SDBM. For some reason the default in
246  my system had issues after reaching a limit of entries.
247  SDBM seems stable so force it.
248- Optimizations in session caching.
249- Added support for session tickets. This allows a
250  server to avoid using a session cache and still support
251  session resumption. This is at the cost of transporting
252  session data during handshake. New option
253  GnuTLSSessionTickets [on|off]
254- Depend on gnutls 2.10.0 to force support for safe
255  renegotiation.
257** Version 0.5.6 (2010-03-24)
258- Corrected issue with firefox and long POST data (by
259  handling EINTR and EAGAIN errors in read).
260- Added support for chained client certificates
261- Corrected more issues related to double frees
264** Version 0.5.5 (2009-06-13)
265- Removed limits on CA certificate loading. Reported by
266  Sander Marechal and Jack Bates.
267- Do not allow sending empty TLS packets even when instructed to.
268  This had the side effect of clients closing connection.
270** Version 0.5.4 (2009-01-04)
271- mod_gnutls.h: modified definition to extern to avoid compilation
272  errors in darwin.
273- Added patch to fix issue with mod_proxy. Investigation and patch by Alain
274  Knaff.
275- libgnutls detection uses pkg-config.
277** Version 0.5.3 (2008-10-16)
278- Corrected bug to allow having an OpenPGP-only web site.
279- Increased Max handshake tries due to interrupted system calls.
281** Version 0.5.2 (2008-06-29)
282- Depend on gnutls 2.4 which has openpgp support in main library.
284** Version 0.5.1 (2008-03-05)
285- Added --disable-srp configure option
286- Better check for memcache (patch by Guillaume Rousse)
287- Corrected possible memory leak in DBM support for resuming sessions.
289** Version 0.5.0-alpha (2008-01-24)
290- Added support for OpenPGP keys. The new directives are:
291  GnuTLSPGPKeyringFile, GnuTLSPGPCertificateFile, GnuTLSPGPKeyFile
293** Version 0.4.2 (2007-12-10)
294- Added support for sending a certificate chain.
295- Corrected bug which did not allow the TLS session cache to be used.
296- Do not allow resuming sessions on different servers.
298** Version 0.4.1 (2007-12-03)
299- Added support for subject alternative names in certificates.
300Only one per certificate is supported.
301- New enviroment variables: SSL_CLIENT_M_VERSION, SSL_CLIENT_S_SAN%,
303- The compatibility mode can now be enabled explicitely with the
304%COMPAT keyword at the GnuTLSPriorities string. It is no longer the default.
305- Check for GnuTLSPriorities directive. This corrects a segfault. Thanks
306to David Hrbáč.
307- Better handling of GnuTLSDHFile and GnuTLSRSAFile.
308- No longer default paths for RSA and DH parameter files.
