16 about ihl. (Check the IP version field first!)

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

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

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

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

127 For links involving mobile sites:
128 * Use source of NAK packets as hint for peer transport address.

149 Other minor improvements:

151 * When printing version (eg during startup), use value from git-describe
152 and thus include git commit id where applicable.
153 * Updates to release checklist in Makefile.in.
154 * Use C99 _Bool for bool_t.
