22 * Ignore IPv6 Unique Local unicast addresses.
23 * Skip "tentative" IPv6 local addresses.
24 * Improve logging and debug output.
27 * Build where size_t is not compatible with int.
29 Build system and packaging fixes:
30 * Makefile: support DESTDIR.
31 * debian/rules: set DESTDIR (not prefix).
32 * debian/rules: Support dpkg-buildflags.
33 * Install ipaddrset.py and secnet.8 with correct permissions.
34 * Fix check for <linux/if_tun.h> and git rid of our copy.
35 * Use -lresolv only if inet_aton is not found otherwise.
36 * Use -lnsl only if inet_ntoa is not found otherwise.
37 * debian/rules: Provide build-arch and build-indep targets.
38 * debian/rules: Do not run build for *-indep (!)
39 * Makefile.in: Putative dual (backport and not) release build process doc.
42 * Update to GPLv3. Add missing copyright notices and credits.
43 * Get rid of old FSF street address; use URL instead.
44 * Remove obsolete LICENCE.txt (which was for snprintf reimplementation).
45 * Remove obsolete references to Cendio (for old ipaddr.py).

49 secnet (0.4.0~beta1) unstable; urgency=low
52 * Support transport over IPv6. (We do not yet carry IPv6 in the private
53 network.) IPv6 support depends on IPv6-capable adns (adns 1.5.x).
54 * New polypath comm, which can duplicate packets so as to send them via
55 multiple routes over the public network, for increased
56 reliability/performance (but increased cost). Currently Linux-only
57 but should be fairly easy to port.
58 * Support multiple public addresses for peers.
59 * Discard previously-received packets (by default).
62 * Report (each first) transmission and reception success and failure.
63 * Log reason for DNS reolution failure.
64 * Log unexpected kinds of death from userv.
65 * Log authbind exit status as errno value (if appropriate).
67 Configuration adjustments:
68 * Adjust default number of mobile peer addresses to store when a peer
69 public address is also configured.
70 * Make specifying peer public port optional. This avoids making special
71 arrangements to bind to a port for in mobile sites with no public
75 * Hackypar children will die if they get a terminating signal.
76 * Fix signal dispositions inherited by secnet's child processes.
77 * Fix off-by-one error which prevented setting transport-peers-max to 5.
79 Test, build and internal improvements:
80 * Use conventional IP address handling library ipaddr.py.
81 * Provide a fuzzer for the slip decoder.
82 * Build system improvements.
83 * Many source code cleanups.

91 one is better. Thanks to Simon Tatham for the report and the patch.

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

113 incompatible modern ipaddr.py is installed (eg via python-ipaddr.deb).

117 For links involving mobile sites:
118 * Use source of NAK packets as hint for peer transport address.
119 * When initiating rekey, make use of data transport peer addresses.

134 For links involving mobile sites:

137 (and other name-resolution improvements).
139 Other minor improvements:
140 * Log peer addresses on key exchange timeout.
141 * When printing version (eg during startup), use value from git-describe
142 and thus include git commit id where applicable.
143 * Updates to release checklist in Makefile.in.
144 * Use C99 _Bool for bool_t.
