4 * Ignore IPv6 Unique Local unicast addresses.
5 * Skip "tentative" IPv6 local addresses.
6 * Improve logging and debug output.
9 * Build where size_t is not compatible with int.
11 Build system and packaging fixes:
12 * Makefile: support DESTDIR.
13 * debian/rules: set DESTDIR (not prefix).
14 * debian/rules: Support dpkg-buildflags.
15 * Install ipaddrset.py and secnet.8 with correct permissions.
16 * Fix check for <linux/if_tun.h> and git rid of our copy.
17 * Use -lresolv only if inet_aton is not found otherwise.
18 * Use -lnsl only if inet_ntoa is not found otherwise.
19 * debian/rules: Provide build-arch and build-indep targets.
20 * debian/rules: Do not run build for *-indep (!)
23 * Update to GPLv3. Add missing copyright notices and credits.
24 * Get rid of old FSF street address; use URL instead.
25 * Remove obsolete LICENCE.txt (which was for snprintf reimplementation).
26 * Remove obsolete references to Cendio (for old ipaddr.py).
30 secnet (0.4.0~beta1) unstable; urgency=low
33 * Support transport over IPv6. (We do not yet carry IPv6 in the private
34 network.) IPv6 support depends on IPv6-capable adns (adns 1.5.x).
35 * New polypath comm, which can duplicate packets so as to send them via
36 multiple routes over the public network, for increased
37 reliability/performance (but increased cost). Currently Linux-only
38 but should be fairly easy to port.
39 * Support multiple public addresses for peers.
40 * Discard previously-received packets (by default).
43 * Report (each first) transmission and reception success and failure.
44 * Log reason for DNS reolution failure.
45 * Log unexpected kinds of death from userv.
46 * Log authbind exit status as errno value (if appropriate).
48 Configuration adjustments:
49 * Adjust default number of mobile peer addresses to store when a peer
50 public address is also configured.
51 * Make specifying peer public port optional. This avoids making special
52 arrangements to bind to a port for in mobile sites with no public
56 * Hackypar children will die if they get a terminating signal.
57 * Fix signal dispositions inherited by secnet's child processes.
58 * Fix off-by-one error which prevented setting transport-peers-max to 5.
60 Test, build and internal improvements:
61 * Use conventional IP address handling library ipaddr.py.
62 * Provide a fuzzer for the slip decoder.
63 * Build system improvements.
64 * Many source code cleanups.

71 * The previous security fix to buffer handling was entirely wrong. This
72 one is better. Thanks to Simon Tatham for the report and the patch.

79 * Pass correct size argument to recvfrom. This is a serious security
80 problem which may be exploitable from outside the VPN.
81 * Fix a memory leak in some error logging.
84 * Two other latent bugs in buffer length handling found and fixed.
85 * Non-critical stylistic improvements to buffer length handling, to make
86 the code clearer and to assist audit.

92 Installation compatibility fix:
93 * In make-secnet-sites, always use our own ipaddr.py even if the
94 incompatible modern ipaddr.py is installed (eg via python-ipaddr.deb).

98 For links involving mobile sites:
99 * Use source of NAK packets as hint for peer transport address.
100 * When initiating rekey, make use of data transport peer addresses.
103 * Provide clean target in test-example/Makefile.

115 For links involving mobile sites:
116 * SECURITY: Properly update peer address array when it is full.
117 * Do name-resolution on peer-initiated key setup too, when we are mobile
118 (and other name-resolution improvements).
120 Other minor improvements:
121 * Log peer addresses on key exchange timeout.
122 * When printing version (eg during startup), use value from git-describe
123 and thus include git commit id where applicable.
124 * Updates to release checklist in Makefile.in.
125 * Use C99 _Bool for bool_t.

160 * Fix formatting error in p-t-p startup message.
161 * Do not send ICMP errors in response to unknown incoming ICMP.
