9 | Security fix: |
10 | * make-secnet-sites: Don't allow setting new VPN-level properties | |
11 | when restricted. This could allow denial of service by | |
12 | users with delegated authorisation. [Mark Wooding] | |
13 | ||
14 | Bugfixes for poor network environments: | |
15 | * polypath: cope properly with asymmetric routing, by correcting | |
ef7be25b IJ |
16 | the handling of late duplicated packets etc. Protocol is now |
17 | incompatible with secnet prior to 0.3.0 when either end is mobile. | |
8c944ec9 IJ |
18 | * Randomise key setup retry time. |
19 | ||
20 | Other bugfixes: | |
21 | * rsa and cbcmac: Fix configuration error messages. [Mark Wooding] | |
22 | * Handle IPv4 addresses properly (ie, not foolishly byte-swapped), | |
23 | when IPv6 is not available. [Mark Wooding] | |
24 | * Better logging (and less foolish debug), especially about whether | |
25 | key is set up, and about crossed key setup attempts. | |
26 | * Internal refactoring and fixes. [Ian Jackson and Mark Wooding] | |
27 | ||
28 | Build system and portability: | |
29 | * configure: rerun autogen.sh with autoconf 2.69-10 | |
30 | * Avoid memset(0,0,0) wrt st->sharedsecret. (Fixes compiler warning; | |
31 | in theory might cause miscompilation.) [Mark Wooding] | |
32 | ||
33 | Documentation: | |
34 | * README.make-secnet-sites: new documentation file. [Mark Wooding] | |
35 | * NOTES: Describe current allocation of capability bits. [Mark Wooding] | |
36 | * NOTES: tiny fix tot protocol description. | |
37 | * secnet(8): Delete wrong information about dh groups. [Mark Wooding] | |
38 | ||
9c6a8729 IJ |
39 | Administrivia: |
40 | * Fix erroneous GPL3+ licence notices "version d or later" (!) | |
8c944ec9 | 41 | * .dir-locals.el: Settings for Python code. [Mark Wooding] |

47 | Security improvement: |

50 | Enhancements: | |
86420bb7 IJ |
51 | * Implement comm-info and dedicated-interface-addr feature, for |
52 | benefit of hippotat. | |
e6d6991c | 53 | * Implement `keepalive' site option, to try to keep link always up. |
dc905acb IJ |
54 | |
55 | Build etc. fixes: | |
658e8a99 IJ |
56 | * #include <limits.h> (fixes the build on jessie). |
57 | * Tolerate building from a git checkout, but with git not installed. | |
58 | (This can happen in chroots.) | |
dc905acb IJ |
59 | * Turn off -Wsign-compare for bison output. |
60 | * Makefile.in: Fix `check-ipaddrset' rule to get reference from | |
61 | $(srcdir). (Makes out-of-tree builds work properly.) | |
658e8a99 IJ |
62 | * Release checklist fixes. |
63 | * Burn version numbers 0.4.1 and 0.4.2 due to errors in release prep. | |
dc905acb IJ |
64 | |
65 | Bugfixes: | |

66 | * When printing messages about dropping IPv6, do not print anything |
67 | about ihl. (Check the IP version field first!) | |
cb807040 | 68 | * When turning on debug, turn on verbose too. |

98 | * debian/rules: Provide build-arch and build-indep targets. | |
99 | * debian/rules: Do not run build for *-indep (!) | |
ca535922 | 100 | * Makefile.in: Putative dual (backport and not) release build process doc. |

102 | Copyright updates: |
103 | * Update to GPLv3. Add missing copyright notices and credits. | |
104 | * Get rid of old FSF street address; use URL instead. | |
105 | * Remove obsolete LICENCE.txt (which was for snprintf reimplementation). | |
106 | * Remove obsolete references to Cendio (for old ipaddr.py). | |

6c23d95c | 111 | |
1e36b4e9 IJ |
112 | New features: |
113 | * Support transport over IPv6. (We do not yet carry IPv6 in the private | |
114 | network.) IPv6 support depends on IPv6-capable adns (adns 1.5.x). | |
115 | * New polypath comm, which can duplicate packets so as to send them via | |
116 | multiple routes over the public network, for increased | |
117 | reliability/performance (but increased cost). Currently Linux-only | |
118 | but should be fairly easy to port. | |
119 | * Support multiple public addresses for peers. | |
120 | * Discard previously-received packets (by default). | |
121 | ||
122 | Logging improvements: | |
123 | * Report (each first) transmission and reception success and failure. | |
124 | * Log reason for DNS reolution failure. | |
125 | * Log unexpected kinds of death from userv. | |
126 | * Log authbind exit status as errno value (if appropriate). | |
127 | ||
128 | Configuration adjustments: | |
129 | * Adjust default number of mobile peer addresses to store when a peer | |
130 | public address is also configured. | |
131 | * Make specifying peer public port optional. This avoids making special | |
132 | arrangements to bind to a port for in mobile sites with no public | |
133 | stable address. | |
134 | ||
135 | Bugfixes: | |
136 | * Hackypar children will die if they get a terminating signal. | |
137 | * Fix signal dispositions inherited by secnet's child processes. | |
138 | * Fix off-by-one error which prevented setting transport-peers-max to 5. | |
139 | ||
140 | Test, build and internal improvements: | |
141 | * Use conventional IP address handling library ipaddr.py. | |
142 | * Provide a fuzzer for the slip decoder. | |
143 | * Build system improvements. | |
144 | * Many source code cleanups. | |

150 | SECURITY FIX: | |
151 | * The previous security fix to buffer handling was entirely wrong. This | |
152 | one is better. Thanks to Simon Tatham for the report and the patch. | |

156 | secnet (0.3.3) unstable; urgency=high |
157 | ||
158 | SECURITY FIXES: | |
159 | * Pass correct size argument to recvfrom. This is a serious security | |
160 | problem which may be exploitable from outside the VPN. | |
161 | * Fix a memory leak in some error logging. | |
162 | ||
163 | Other related fixes: | |
164 | * Two other latent bugs in buffer length handling found and fixed. | |
165 | * Non-critical stylistic improvements to buffer length handling, to make | |
166 | the code clearer and to assist audit. | |

170 | secnet (0.3.3~beta1) unstable; urgency=low |
171 | ||
172 | Installation compatibility fix: | |
173 | * In make-secnet-sites, always use our own ipaddr.py even if the | |
174 | incompatible modern ipaddr.py is installed (eg via python-ipaddr.deb). | |
175 | (Future versions of secnet are going to need that Python module to be | |
176 | installed.) | |
177 | ||
178 | For links involving mobile sites: | |
179 | * Use source of NAK packets as hint for peer transport address. | |
180 | * When initiating rekey, make use of data transport peer addresses. | |
181 | ||
182 | Build fix: | |
183 | * Provide clean target in test-example/Makefile. | |
