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 - [test suite] Added parsing of valgrind output to produce a listing of
15 functions that have been flagged - this assists in the development
16 process to ensure that fwknop is not leaking memory.
17 - Minor gcc warning fix: fko_decode.c:43:17: warning: variable ‘edata_size’
18 set but not used [-Wunused-but-set-variable].
20 fwknop-2.0 (01/02/2012):
21 - This is the first production release that has been completely re-written
22 in C. This brings Single Packet Authorization functionality to all sorts
23 of machines from embedded devices to large systems. iptables, ipfw, and
24 pf firewalls are supported by the fwknopd daemon, and the fwknop client
25 is known to work on most major *NIX environments, the iPhone and Android
26 operating systems, and Cygwin under Windows.
27 - Added FORCE_NAT mode to the access.conf file so that for any valid SPA
28 packet, force the requested connection to be NAT'd through to the
29 specified (usually internal) IP and port value. This is useful if there
30 are multiple internal systems running a service such as SSHD, and you
31 want to give transparent access to only one internal system for each
32 stanza in the access.conf file. This way, multiple external users can
33 each directly access only one internal system per SPA key.
34 - Added two new access.conf variables are added "ACCESS_EXPIRE" and
35 "ACCESS_EXPIRE_EPOCH" to allow access stanzas to be expired without
36 having to modify the access.conf file and restart fwknopd.
37 - Added a new feature to allow an access stanza that matches the SPA source
38 address to not automatically short circuit other stanzas if there is an
39 error (such as when there are multiple encryption keys involved and an
40 incoming SPA packet is meant for, say, the second stanza and the first
41 therefore doesn't allow proper decryption).
42 - Bug fix to exclude SPA packets with timestamps in the future that are too
43 great (old packets were properly excluded already).
44 - Bug fix to honor the fwknop client --time-offset-plus and
45 --time-offset-minus options
46 - Added DNAT mode tests, minor memory leak fix in NAT mode, added fwknopd
47 check for ENABLE_IPT_FORWARDING variable before attempting NAT access.
48 - [test suite] Added --diff mode to compare results from one execution to
