Update documentation on ALPN and HTTP/2

  • Property mode set to 100644
File size: 11.4 KB
1** Version 0.9.0 UNRELEASED
2- Security fix: Refuse to send or receive any data over a failed TLS
3  connection (commit 72b669eae8c45dda1850e8e5b30a97c918357b51). This
4  could lead to requests on reverse proxy TLS connections being sent
5  in plain text, and might allow faking requests in plain text.
6- Security fix: Reject HTTP requests if they try to access virtual
7  hosts that do not match their TLS connections (commit
8  de3fad3c12f53cdbf082ad675e4b10f521a02811). Additionally check if SNI
9  and Host header match.
10- OCSP stapling is now enabled by default, if possible. OCSP responses
11  are updated regularly and stored in a cache separate from the
12  session cache. The OCSP cache uses mod_socache_shmcb by default
13  (if the module is loaded, no other configuration required).
14- Session tickets are now enabled by default if using GnuTLS 3.6.4 or
15  newer. GnuTLS 3.6.4 introduced automatic rotation for the used key,
16  and TLS 1.3 takes care of other reasons not to use tickets while
17  requiring them for session resumption. Note that there is currently
18  no mechanism to synchronize ticket keys across a cluster of servers.
19- The internal cache implementation has been replaced with
20  mod_socache. Users may need to update their GnuTLSCache settings and
21  load the appropriate socache modules.
22- ALPN (required for HTTP/2) now works correctly with different
23  "Protocols" directives between virtual hosts if building with GnuTLS
24  3.6.3 or newer. Older versions require identical "Protocols"
25  directives for overlapping virtual hosts. Thanks to Vincent Tamet
26  for the bug report!
27- GnuTLSPriorities is optional now and defaults to "NORMAL" if
28  missing. The same applies to GnuTLSProxyPriorities (if TLS proxy is
29  enabled).
30- The manual is now built as a manual page, too, if pandoc is
31  available.
32- OpenPGP support has been removed.
34** Version 0.8.4 (2018-04-13)
35- Support Apache HTTPD 2.4.33 API for proxy TLS connections
36- Support TLS for HTTP/2 connections with mod_http2
37- Fix configuration of OCSP stapling callback
39** Version 0.8.3 (2017-10-20)
40- Use GnuTLS' default DH parameters by default
41- Handle long Server Name Indication data and gracefully ignore
42  unknown SNI types
43- Send SNI for proxy connections
44- Deprecate OpenPGP support like GnuTLS did (will be removed
45  completely in a future release)
46- Do not announce session ticket support for proxy connections
47- Minor documentation updates (SSL_CLIENT_I_DN, reference for SNI)
48- Test suite: Simplify handling of proxy backend servers and OCSP
49  responders
50- Test suite: stability/compatibility fixes
52** Version 0.8.2 (2017-01-08)
53- Test suite: Ensure CRLF line ends in HTTP headers
54- Test suite, gen_ocsp_index.c: Handle serial as fixed order byte array
56** Version 0.8.1 (2016-12-20)
57- Bugfix: Use APR_SIZE_T_FMT for portable apr_size_t formatting
59** Version 0.8.0 (2016-12-11)
60- New: Support for OCSP stapling
61- Bugfix: Access to DBM cache is locked using global mutex
62  "gnutls-cache"
63- Bugfix: GnuTLSSessionTickets is now disabled by default as described
64  in the handbook
65- Fixed memory leak while checking proxy backend certificate
66- Fixed memory leaks in post_config
67- Safely delete session ticket key (requires GnuTLS >= 3.4)
68- Improved error handling in post_config hook
69- Various handbook updates
70- Internal API documentation can be generated using Doxygen
71- Unused code has been removed (conditionals for GnuTLS 2.x and Apache
72  versions before 2.2, internal Lua bytecode structure last used in
73  2011).
74- Test suite: Fixed locking for access to the PGP keyring of the test
75  certificate authority
76- mod_gnutls can be built using Clang (unsupported)
78** Version 0.7.5 (2016-05-28)
79- Sunil Mohan Adapa reported retry loops during session shutdown in
80  cleanup_gnutls_session() due to gnutls_bye() incorrectly returning
81  GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN. Setting the GnuTLS session
82  errno in mgs_transport_write() fixes the problem.
83- Import Daniel Kahn Gillmor's patches for GnuPG v2 support from the
84  Debian package.
85- Build system improvements that allow VPATH builds and get "make
86  distcheck" to work
88** Version 0.7.4 (2016-04-13)
89- Support SoftHSM 2 for PKCS #11 testing
90- Increase verbosity of test logs
92** Version 0.7.3 (2016-01-12)
93- Update test suite for compatibility with GnuTLS 3.4, which has
94  stricter key usage checks and priorities than 3.3.
95- Write non-HTML output to mod_status reports if AP_STATUS_SHORT is
96  set (mod_status sets it for requests with the "auto" parameter, e.g.
97  https://localhost/server-status?auto).
98- Register "ssl_is_https" function so the special mod_rewrite variable
99  %{HTTPS} works correctly with mod_gnutls. The new test case for this
100  requires Wget or curl. Fixes Debian bug #514005.
101- Test suite servers listen on IPv4 *and* IPv6 loopback addresses by
102  default (other addresses configurable), which should fix failures
103  due to localhost randomly resolving to either on some distributions.
104- Isolate tests using network namespaces, if possible. This avoids
105  port conflicts with other test cases (so they can run in parallel)
106  and host services.
107- Support for local Apache drop-in config files in the test suite
108  (e.g. to load additional modules needed on Fedora).
109- Try to use markdown to build HTML documentation if pandoc is not
110  available.
111- Disable use of flock if it is unavailable or does not support
112  timeouts (the latter caused the build to fail on Debian Hurd).
113- New test: Disable TLS 1.0 (regression test for Debian bug #754960).
115** Version 0.7.2 (2015-11-21)
116- Bugfix: Non-blocking reads in the input filter could lead to a busy
117  wait in the gnutls_io_input_read function, causing high load on
118  Keep-Alive connections waiting for data, until either more data
119  could be received or the connection was closed. The fix is to pass
120  EAGAIN/EINTR results up to the input filter so they can be handled
121  properly.
122- Close TLS session if the input filter receives EOF (mostly relevant
123  for proper termination of proxy connections).
124- Remove dependency on APR Memcache, which is replaced by the newer
125  version included in the APR Utility Library (libaprutil).
126- Remove dependency on bc. It was used for floating point arithmetic
127  in the test suite, the calculations have been changed to use
128  integers and pure bash code.
130** Version 0.7.1 (2015-10-18)
131- Improved handling of PKCS #11 modules: mod_gnutls now loads either
132  modules specified using GnuTLSP11Module, or the system defaults, but
133  not both. Thanks to Nikos Mavrogiannopoulos for the report and
134  initial patch!
135- Initialize variables to safe defaults during client certificate
136  verification. Certain error code paths did not set them, but they
137  should never be hit due to config validation. This adds another line
138  of defense.
139- Enable C99 support via autoconf
140- Test suite improvements. Most importantly, automake now handles
141  environment setup without any external make calls. Rules to build
142  the certificates are included from the old test makefile. Note that
143  the dependency on GNU make is not new (the test makefile always used
144  GNU make syntax), it just wasn't listed explicitly.
146** Version 0.7 (2015-07-12)
147- Security fix for TLS client authentication (CVE-2015-2091)
148- Bug fixes that enable support for reverse proxy operation
149- Various test suite improvements. Tests are configured through autoconf,
150  so the test suite now works for builds without Monkeysphere support.
151- Add support for TLS connections to back end servers when operating as a
152  reverse proxy (X.509 authentication only at the moment).
153- PKCS #11 support for server keys and certificates
154- Use strict compiler arguments by default (-Wall -Werror -Wextra)
155- Allow limiting the size of certificates exported as SSL_SERVER_CERT
156  and SSL_CLIENT_CERT through the GnuTLSExportCertificates directive
158** Version 0.6 (2014-02-17)
159- Generating DH Params instead of using static ones.
160- Now considering ServerAlias Directives.
161- Major Legacy Code Cleanup.
162- html and pdf and manual documentation generated from markdown sources
163- support monkeysphere validation agent (MSVA) client-certificate verification
164- wider test suite
165- GnuTLSExportCertificates off by default
167** Version 0.5.10 (2011-07-12)
168- Patched a bug responsible for excessive memory consumption by mod_gnutls.
169- Support for proxying from SSL to plain HTTP was added (ie. proxy termination).
171** Version 0.5.9 (2010-09-24)
172- GnuTLSCache none is now an allowed option.
173- Corrected behavior in Keep-Alive connections (do not
174  terminate the connection prematurely)
175- The GnuTLSCache variable now can be given the specific
176  option "gdbm" instead of "dbm". "dbm" will use the berkeley
177  db type of libapr while gdbm will force gdbm to be used.
178  sdbm is no longer being used due to serious limitations.
180** Version 0.5.8 (2010-08-18)
181- Session tickets are enabled by default.
182- Fixes some segmentation faults noticed in some
183  configurations.
185** Version 0.5.7 (2010-07-01)
186- Force usage of SDBM. For some reason the default in
187  my system had issues after reaching a limit of entries.
188  SDBM seems stable so force it.
189- Optimizations in session caching.
190- Added support for session tickets. This allows a
191  server to avoid using a session cache and still support
192  session resumption. This is at the cost of transporting
193  session data during handshake. New option
194  GnuTLSSessionTickets [on|off]
195- Depend on gnutls 2.10.0 to force support for safe
196  renegotiation.
198** Version 0.5.6 (2010-03-24)
199- Corrected issue with firefox and long POST data (by
200  handling EINTR and EAGAIN errors in read).
201- Added support for chained client certificates
202- Corrected more issues related to double frees
205** Version 0.5.5 (2009-06-13)
206- Removed limits on CA certificate loading. Reported by
207  Sander Marechal and Jack Bates.
208- Do not allow sending empty TLS packets even when instructed to.
209  This had the side effect of clients closing connection.
211** Version 0.5.4 (2009-01-04)
212- mod_gnutls.h: modified definition to extern to avoid compilation
213  errors in darwin.
214- Added patch to fix issue with mod_proxy. Investigation and patch by Alain
215  Knaff.
216- libgnutls detection uses pkg-config.
218** Version 0.5.3 (2008-10-16)
219- Corrected bug to allow having an OpenPGP-only web site.
220- Increased Max handshake tries due to interrupted system calls.
222** Version 0.5.2 (2008-06-29)
223- Depend on gnutls 2.4 which has openpgp support in main library.
225** Version 0.5.1 (2008-03-05)
226- Added --disable-srp configure option
227- Better check for memcache (patch by Guillaume Rousse)
228- Corrected possible memory leak in DBM support for resuming sessions.
230** Version 0.5.0-alpha (2008-01-24)
231- Added support for OpenPGP keys. The new directives are:
232  GnuTLSPGPKeyringFile, GnuTLSPGPCertificateFile, GnuTLSPGPKeyFile
234** Version 0.4.2 (2007-12-10)
235- Added support for sending a certificate chain.
236- Corrected bug which did not allow the TLS session cache to be used.
237- Do not allow resuming sessions on different servers.
239** Version 0.4.1 (2007-12-03)
240- Added support for subject alternative names in certificates.
241Only one per certificate is supported.
242- New enviroment variables: SSL_CLIENT_M_VERSION, SSL_CLIENT_S_SAN%,
244- The compatibility mode can now be enabled explicitely with the
245%COMPAT keyword at the GnuTLSPriorities string. It is no longer the default.
246- Check for GnuTLSPriorities directive. This corrects a segfault. Thanks
247to David Hrbáč.
248- Better handling of GnuTLSDHFile and GnuTLSRSAFile.
249- No longer default paths for RSA and DH parameter files.
