16 * When printing messages about dropping IPv6, do not print anything
17 about ihl. (Check the IP version field first!)
18 * When turning on debug, turn on verbose too.

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

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

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

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

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

145 For links involving mobile sites:
146 * SECURITY: Properly update peer address array when it is full.

148 (and other name-resolution improvements).
150 Other minor improvements:
151 * Log peer addresses on key exchange timeout.
152 * When printing version (eg during startup), use value from git-describe
153 and thus include git commit id where applicable.
154 * Updates to release checklist in Makefile.in.
155 * Use C99 _Bool for bool_t.
