29defca @mrash (Jonathan Bennett) added script to create QR codes from…
4 - Contributed the script (in extras/console-qr/) to create
5 QR codes from fwknopd access.conf keys.
bcba9d6 @mrash added CREDITS file, bumped software version, added ChangeLog files
7 Sebastien Jeanquier
8 - Assisted with getting fwknop included in BackTrack Linux - the choice
bfdbb8f @mrash Updated authorship and copyright information
9 distro for pentration testers.
bcba9d6 @mrash added CREDITS file, bumped software version, added ChangeLog files
11 Ozmart
12 - Suggested the idea for setting an access stanza expiration time.
13 - Suggested the abiliy to have certain incoming connections automatically
14 NAT'd through to specific internal systems. The result was the FORCE_NAT
15 mode.
16 - Assisted with getting fwknop running under the Pentoo Linux distro.
18 Max Kastanas
19 - Contributed both an Android and an iPhone fwknop client port - see the
20 top level android/ and iphone/ directories.
5c26c0a @mrash added Ted Wynnychenko for OpenBSD PF testing
22 Ted Wynnychenko
23 - Helped test fwknop PF support on OpenBSD.
ba3b7d1 @mrash Bug fix for multi-stanza key use and replay attack detection
25 Andy Rowland
26 - Reported a bug where the same encryption key used for two stanzas in the
27 access.conf file would result in access requests that matched the second
28 stanza to always be treated as a replay attack. This has been fixed for
29 the fwknop-2.0.1 release.
5387242 @mrash PCAP_LOOP_SLEEP bug fix to 1/10th of a second
31 C Anthony Risinger
32 - Caught a bug where the default PCAP_LOOP_SLEEP value was 1/100th of a
33 second instead of the intended default of 1/10th of a second.
3c533de @mrash updated Debian init script (contributed by Franck Joncourt)
35 Franck Joncourt
36 - fwknop Debian package maintainer.
37 - Contributed a new Debian init script.
67f5d1f @mrash Applied perl FKO module libfko path patch from Franck Joncourt
38 - Contributed a patch to have the perl FKO module link against libfko in
39 the local directory (if it exists) so that it doesn't have to have libfko
40 completely installed in /usr/lib/. This allows the test suite to run FKO
41 tests without installing libfko.
627035f @mrash Patch from Franck Joncourt for setting permissions via open()
42 - Contributed a patch to remove unnecessary chmod() call when creating
43 client rc file and server replay cache file. The permissions are now set
44 appropriately via open(), and at the same time this patch fixes a
45 potential race condition since the previous code used fopen() followed by
46 chmod().
03b222d @mrash [client] (Franck Joncourt) Fixed Ctrl-C problem where SPA packets wer…
47 - Contributed a patch to allow the fwknop client to be stopped with Ctrl-C
48 before sending an SPA packet on the wire.
fd41308 @mrash added info for Franck's latest contribution
49 - Contributed a patch to ensure that duplicate iptables rules are not
50 created even for different SPA packets that arrive at the same time and
51 request the same access.
77c876c @mrash credits and changelog updates
52 - Added support for resolving hostnames in various NAT modes (fixes issue
53 #43 in github).
892ee15 @mrash ChangeLog and credits updates for Franck
54 - Bug fix in the client for resolving hostnames in '-P icmp' mode (fixes
55 issue #64).
77c876c @mrash credits and changelog updates
56 - Added support for saving fwknop client command line arguments via a new
66399fe @mrash Merge remote-tracking branch 'fjoncourt/master'
57 option --save-rc-stanza.
892ee15 @mrash ChangeLog and credits updates for Franck
58 - Added log module support for the client.
66399fe @mrash Merge remote-tracking branch 'fjoncourt/master'
59 - Added the ability to read a passphrase from STDIN and also from a file
60 descriptor via --fd (closes #74).
0ecc2d2 @mrash minor docs update
61 - Added libfko unit tests via the CUnit framework.
7061b7b @mrash added Jonathan Schulz
63 Jonathan Schulz
64 - Submitted patches to change HTTP connection type to 'close' for -R mode
65 in the client and fix a bug for recv() calls against returned HTTP data.
fd30440 @mrash added Aldan Beaubien for reporting the Morpheus NULL IP problem
67 Aldan Beaubien
68 - Reported an issue with the Morpheus client sending SPA packets with NULL
69 IP addresses, and code was added to fwknopd to better validate incoming
70 SPA data as a result of this report.
fbdae50 @mrash added Geoff Carstairs for the FORCE_NAT idea
72 Geoff Carstairs
73 - Suggested a way to redirect valid connection requests to a specific
74 internal service via NAT, configurable by each stanza in access.conf.
75 This allows for better access control for multple users requiring access
76 to multiple internal systems, in a manner that is transparent to the
77 user. The result was the FORCE_NAT mode.
543de16 @mrash [server] iptables 'comment' match check
79 Hank Leininger
45e29f6 @mrash minor edit to credits file for Hank Leininger
80 - Contributed a patch to greatly extend libfko error code descriptions at
81 various places in order to give much better information on what certain
82 error conditions mean. Closes #98.
83 - Suggested the ability to read a passphrase from STDIN and via a new --fd
84 command line argument (github #74) to allow things like:
85 $ gpg -d passphrasefile.pgp | fwknop -R -n myserver
543de16 @mrash [server] iptables 'comment' match check
86 - For iptables firewalls, suggested a check for the 'comment' match to
87 ensure the local environment will properly support fwknopd operations.
88 The result is the new ENABLE_IPT_COMMENT_CHECK functionality.
d46ba1c @mrash (Fernando Arnaboldi, IOActive) Found and fixed several DoS/code execu…
90 Fernando Arnaboldi (IOActive)
91 - Found important buffer overflow conditions for authenticated SPA clients
92 in the fwknopd server (pre-2.0.3). These findings enabled fixes to be
93 developed along with a new fuzzing capability in the test suite.
f4c16bc @mrash [server] Stronger IP validation based on a bug found by Fernando Arna…
94 - Found a condition in which an overly long IP from malicious authenticated
95 clients is not properly validated by the fwknopd server (pre-2.0.3).
e2c0ac4 @mrash [server] Strong access.conf validation
96 - Found a local buffer overflow in --last processing with a maliciously
97 constructed ~/ file. This has been fixed with proper
98 validation of arguments.
99 - Found several conditions in which the server did not properly throw out
100 maliciously constructed variables in the access.conf file. This has been
101 fixed along with new fuzzing tests in the test suite.
591416e @mrash [server] bug fix in --disable-file-cache mode
103 Vlad Glagolev
104 - Submitted a patch to fix ndbm/gdbm usage when --disable-file-cache is
105 used for the autoconf configure script. This functionality was broken in
106 be4193d734850fe60f14a26b547525ea0b9ce1e9 through improper handling of
107 #define macros from --disable-file-cache.
f8374c8 @mrash [server] (Vlad Glagolev) Submitted a patch to fix command exec mode
108 - Submitted a patch to fix command exec mode under SPA message type
109 validity test. Support for command exec mode was also added to the test
110 suite.
05eb197 @mrash added the OpenBSD port from Vlad
111 - Submitted an OpenBSD port for fwknop-2.0.3, and this has been checked in
112 under extras/openbsd/.
6f356a9 @mrash Added Sean Greven for his FreeBSD port
114 Sean Greven
115 - Created a port of fwknop for FreeBSD:
2f1768f @mrash minor CREDITS file formatting update
fbbcae3 @mrash [libfko] Don't trundate > 16 byte Rijndael keys
118 Michael T. Dean
119 - Reported the Rijndael key truncation issue for user-supplied keys
120 (passphrases) greater than 16 bytes long.
77c876c @mrash credits and changelog updates
122 George Herlin
123 - Proposed a verification approach to test suite operations, and the result
124 was implemented in a61939c005e2b09d6800e2171f607c9d1948f022. This makes
125 test suite operate equivalently regardless of whether valgrind is used or
126 whether fwknop is being tested on an embedded system with very limited
127 resources.
39115c6 @mrash added Ruhsam Bernhard to the credits file
129 Ruhsam Bernhard
130 - Reported an issue where the message size test would result in long
131 command mode SPA packets not decrypting properly because only GPG decrypt
132 attempts were made. This issue was fixed in
133 7e784df3870373f055a2f0f8d818829501bcb1c0.
5804e15 @mrash Merge remote-tracking branch 'ag4ve/master'
135 Shawn Wilson
136 - Added better SPA source IP logging for various fwknopd logging messages.
137 This helps to make it more clear why certain SPA packets are rejected
138 from some systems.
7cb23c7 @mrash [server] added check to ensure any existing fwknop jump rule is not d…
140 Dan Lauber
141 - Suggested a check for fwknopd to ensure that the jump rule on systems
142 running iptables is not duplicated if it already exists.
6706c53 @mrash [libfko] HMAC comparison timing bug fix
144 Ryman
145 - Reported a timing attack bug in the HMAC comparison operation (#85) and
1c8d247 @mrash ChangeLog update to mention the constant_runtime_cmp() change
146 suggested a fix derived from yaSSL:
6706c53 @mrash [libfko] HMAC comparison timing bug fix
66399fe @mrash Merge remote-tracking branch 'fjoncourt/master'
ffeb285 @mrash [libfko] handle endian detection on PPC (and other) systems
149 Blair Zajac
4d167cd @mrash credit Blair and Tim with MacPorts and Homebrew maintainer status
150 - MacPorts fwknop package maintainer for Mac OS X systems.
ffeb285 @mrash [libfko] handle endian detection on PPC (and other) systems
151 - Contributed patches to handle endian issues on PPC systems.
152 - Reported an issue where strndup() is not available on some PPC systems
153 and the fix is to use the local lib/fko_util.c implementation similarly
154 to Windows builds.
5e3ec3b @mrash [client] in '-M legacy' mode truncate the key to 16 bytes
155 - Suggested throwing an error in '-M legacy' mode to warn users about the
156 inability of older fwknopd daemons to handle Rijndael keys > 16 bytes.
157 Any release after and including 2.5 does not have this limitation.
83952fc @mrash added Radostan Riedel's AppArmor policy note
159 Radostan Riedel
160 - Contributed an AppArmor policy that is known to work on Debian and Ubuntu
161 systems. The policy file is available in extras/apparmor.
3a2c33c @mrash Added Les Aker to credits file
163 Les Aker
164 - Reported an issue with Arch Linux that resulted in fwknopd hanging for a
165 pcap_dispatch() packet count of zero when using libpcap-1.5.1. This
166 issue was tracked on github as issue #110, and the default packet count
167 is now set at 100 as a result.
551b243 @mrash (Marek Wrzosek) Update docs to reflect random 'digits' use instead of…
169 Marek Wrzosek
170 - Suggested doc update to fwknop man pages to accurately describe the usage
171 of digits instead of bytes for SPA random data. About 53 bits of entropy
172 are actually used, although this is in addition to the 64-bit random salt
173 in for key derivation used by PBKDF1 in Rjindael CBC mode.
174 - Various excellent feedback on crypto design, including the need to remove
a347be3 @mrash merged android4.4_support branch
8dfd576 @mrash added Gerry Reno
177 Gerry Reno
178 - Updated the Android client to be compatible with Android-4.4.
179 - Provided guidance on Android client issues along with testing candidate
180 patches to update various things - this work is being tracked in the
181 android4.4_support branch.
aae72a9 @mrash firewalld support from Gerry Reno
182 - Implemented support for firewalld in the fwknopd daemon running on RHEL 7
183 and CentOS 7 systems. This is a major addition to handle yet another
184 firewall architecture.
4d167cd @mrash credit Blair and Tim with MacPorts and Homebrew maintainer status
186 Tim Heckman
187 - Homebrew fwknop package maintainer for Mac OS X systems.
188 - Suggested that fwknop support nftables when it is integrated into the
189 mainline Linux kernel.
74428ad @mrash [server] Bug fix for PF firewalls without ALTQ support on FreeBSD.
191 Barry Allard
192 - Reported bug in PF support on FreeBSD systems where ALTQ is not available
193 would cause new PF rules to not be added (github issue #121).
50434c5 @mrash Use the fwknop User-Agent for wget SSL external IP resolutions
194 - Suggested the abiliy to specify the HTTP User-Agent when wget is used to
195 resolve the external IP via SSL (github issue #134).
00a057a @mrash ChangeLog update for FCS bug fix
197 Bill Stubbs
198 - Submitted a patch to fix a bug where fwknopd could not handle Ethernet
199 frames that include the Frame Check Sequence (FCS) header. This header is
200 four bytes long, and is placed at the end of each Ethernet frame.
201 Normally the FCS header is not visible to libpcap, but some card/driver
202 combinations result in it being included. Bill noticed this on the
203 following platform:
204 BeagleBone Black rev C running 3.8.13-bone50 #1 SMP Tue May 13
205 13:24:52 UTC 2014 armv7l GNU/Linux
c5c263c @mrash add Grant Pannell
207 Grant Pannell
208 - Submitted a patch to add a new access.conf variable "DESTINATION" in
209 order to define the destination address for which an SPA packet will be
210 accepted. The string "ANY" is also accepted if a valid SPA packet should
211 be honored to any destination IP. Similarly to the "SOURCE" variable,
212 networks should be specified in CIDR notation (e.g. ""),
213 and individual IP addresses can be specified as well. Also, multiple IP's
214 and/or networks can be defined as a comma separated list (e.g.
215 ",").
1ce8004 @mrash [server] Bug fix to not include pcap.h in --enable-udp-server mode
217 Alexander Kozhevnikov
218 - Reported a bug when fwknop is compiled with --enable-udp-server where
219 the server was including pcap.h
0ecc2d2 @mrash minor docs update
221 Dan Brooks
222 - Contributed a patch for the Android client app to add the definition of
223 custom server udp port. This is similiar to the --server-port argument
224 offered by the main fwknop client.
Something went wrong with that request. Please try again.
