3 * polypath: Ignore IPv6 Unique Local unicast addresses.
4 * polypath: Skip "tentative" IPv6 local addresses.
5 * polypath: Improve logging and debug output.
6 * Portability fix: Build where size_t is not compatible with int.
7 * Makefile: support DESTDIR.
8 * debian/rules: set DESTDIR (not prefix).
9 * Do not install ipaddrset.py and secnet.8 executable.
10 * Fix check for <linux/if_tun.h>.
14 secnet (0.4.0~beta1) unstable; urgency=low
17 * Support transport over IPv6. (We do not yet carry IPv6 in the private
18 network.) IPv6 support depends on IPv6-capable adns (adns 1.5.x).
19 * New polypath comm, which can duplicate packets so as to send them via
20 multiple routes over the public network, for increased
21 reliability/performance (but increased cost). Currently Linux-only
22 but should be fairly easy to port.
23 * Support multiple public addresses for peers.
24 * Discard previously-received packets (by default).
27 * Report (each first) transmission and reception success and failure.
28 * Log reason for DNS reolution failure.
29 * Log unexpected kinds of death from userv.
30 * Log authbind exit status as errno value (if appropriate).
32 Configuration adjustments:
33 * Adjust default number of mobile peer addresses to store when a peer
34 public address is also configured.
35 * Make specifying peer public port optional. This avoids making special
36 arrangements to bind to a port for in mobile sites with no public
40 * Hackypar children will die if they get a terminating signal.
41 * Fix signal dispositions inherited by secnet's child processes.
42 * Fix off-by-one error which prevented setting transport-peers-max to 5.
44 Test, build and internal improvements:
45 * Use conventional IP address handling library ipaddr.py.
46 * Provide a fuzzer for the slip decoder.
47 * Build system improvements.
48 * Many source code cleanups.

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

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

76 Installation compatibility fix:

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

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

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

102 (and other name-resolution improvements).
104 Other minor improvements:
105 * Log peer addresses on key exchange timeout.
106 * When printing version (eg during startup), use value from git-describe
107 and thus include git commit id where applicable.
108 * Updates to release checklist in Makefile.in.
109 * Use C99 _Bool for bool_t.
