1 fwknop-2.0.1 (07//2012):
2 - Bug fix where the same encryption key used for two stanzas in
3 the access.conf file would result in access requests that matched the
4 second stanza to always be treated as a replay attack. This has been
5 fixed for the fwknop-2.0.1 release, and was reported by Andy Rowland. Now
6 the fwknopd server computes the SHA256 digest of raw incoming payload
7 data before decryption, and compares this against all previous hashes.
8 Previous to this commit, fwknopd would add a new hash to the replay
9 digest list right after the first access.conf stanza match, so when SPA
10 packet data matched the second access.conf stanza a matching replay
11 digest would already be there.
12 - Bug fix for PF firewalls: updated the PF anchor check to not rely on
13 listing the PF policy - use 'pfctl -s Anchor' instead.
14 - Minor gcc warning fix: fko_decode.c:43:17: warning: variable ‘edata_size’
15 set but not used [-Wunused-but-set-variable].
17 fwknop-2.0 (01/02/2012):
18 - This is the first production release that has been completely re-written
19 in C. This brings Single Packet Authorization functionality to all sorts
20 of machines from embedded devices to large systems. iptables, ipfw, and
21 pf firewalls are supported by the fwknopd daemon, and the fwknop client
22 is known to work on most major *NIX environments, the iPhone and Android
23 operating systems, and Cygwin under Windows.
24 - Added FORCE_NAT mode to the access.conf file so that for any valid SPA
25 packet, force the requested connection to be NAT'd through to the
26 specified (usually internal) IP and port value. This is useful if there
27 are multiple internal systems running a service such as SSHD, and you
28 want to give transparent access to only one internal system for each
29 stanza in the access.conf file. This way, multiple external users can
30 each directly access only one internal system per SPA key.
31 - Added two new access.conf variables are added "ACCESS_EXPIRE" and
32 "ACCESS_EXPIRE_EPOCH" to allow access stanzas to be expired without
33 having to modify the access.conf file and restart fwknopd.
34 - Added a new feature to allow an access stanza that matches the SPA source
35 address to not automatically short circuit other stanzas if there is an
36 error (such as when there are multiple encryption keys involved and an
37 incoming SPA packet is meant for, say, the second stanza and the first
38 therefore doesn't allow proper decryption).
39 - Bug fix to exclude SPA packets with timestamps in the future that are too
40 great (old packets were properly excluded already).
41 - Bug fix to honor the fwknop client --time-offset-plus and
42 --time-offset-minus options
43 - Added DNAT mode tests, minor memory leak fix in NAT mode, added fwknopd
44 check for ENABLE_IPT_FORWARDING variable before attempting NAT access.
45 - [test suite] Added --diff mode to compare results from one execution to
