Subject: src/ licensing

Fellow JtR developers -

As promised, here's the portion of john-1.7.9-jumbo-7-licensing.txt
pertaining to src/ files.  I suggest that you search it for the words
unclear, issue, your first name, your nickname, and for question marks -
and try to clarify in your replies.  Thanks!

john-1.7.9-jumbo-7/src:
AFS_fmt.c                       GPLv2; Solar; code
BFEgg_fmt_plug.c                GPL; Sun-Zero; code; the comment says just "the GNU GPL" without clarifying which GPL version (JtR 1.6 had been released without clear indication of license, so a file introduced into the tree in 2002 was not automatically required to be compatible with GPLv2)
BF_fmt.c                        GPLv2; Solar; code
BF_std.c                        GPLv2; Solar; code
BF_std.h                        GPLv2; Solar; code
BSDI_fmt.c                      GPLv2; Solar; code
DES_bs.c                        GPLv2; Solar; code
DES_bs.h                        GPLv2; Solar; code
DES_bs_b.c                      GPLv2; Solar; code
DES_fmt.c                       GPLv2; Solar; code
DES_std.c                       GPLv2; Solar; code
DES_std.h                       GPLv2; Solar; code
DMD5_fmt_plug.c                 unclear; regenrecht, magnum; code; magnum added "No rights reserved" for his changes to the code, but this might not be a sufficiently clear statement, and the copyright status and license of regenrecht's original version is unclear anyway (would have to be compatible with GPLv2 if the file was introduced by the author into JtR 1.7+ tree, but it is currently unclear whether it was originally contributed for pre-1.7 or 1.7+)
DOMINOSEC_fmt_plug.c            unclear; regenrecht; code; no explicit license (same uncertainty as with regenrecht's original for DMD5_fmt_plug.c)
EPI_fmt_plug.c                  unclear; Johannes Gumbel; code; contributed for 1.7.2 by the author, so GPLv2 compatibility may be implied
HDAA_fmt_plug.c                 cut-down BSD; Romain Raboin, magnum; code
IPB2_fmt_plug.c                 unclear; regenrecht; code; no explicit license (same uncertainty as with DOMINOSEC_fmt_plug.c)
KRB4_fmt_plug.c                 3-clause BSD; Dug Song; code
KRB4_std.h                      N/A; Dug Song; code; too minor for copyright
KRB4_std_plug.c                 unclear; KTH Kerberos authors?; code; from OpenBSD tree, and in turn from KTH Kerberos tree - we should be able to find the copyright statement and license there
KRB5_fmt_plug.c                 unclear; Dug Song, Nasko Oskov, KTH, MIT; code; Nasko did not include a license for his changes, the licenses for Heimdal project code may probably be found there
KRB5_std.h                      unclear; Dug Song, Nasko Oskov, KTH, MIT; code; same issue as with KRB5_fmt_plug.c
KRB5_std_plug.c                 unclear; Dug Song, Nasko Oskov, KTH, MIT; code; same issue as with KRB5_fmt_plug.c
KeyDBCracker.c                  GPLv2+; Nagareshwar Y Talekar; code
KeyDBCracker.h                  GPLv2+; Nagareshwar Y Talekar; code
LM_fmt.c                        GPLv2; Solar; code
MD5_fmt.c                       GPLv2; Solar, bartavelle; code; bartavelle's changes in jumbo add SIMD support and extra test vectors, the license is implied to be GPLv2 since the changes were added by the author into 1.7+ (even though sse-intrinsics.c is under cut-down BSD)
MD5_std.c                       GPLv2; Solar; code
MD5_std.h                       GPLv2; Solar, bartavelle; code; bartavelle's changes in jumbo add SIMD support, the license is implied to be GPLv2 since the changes were added by the author into 1.7+ (even though sse-intrinsics.c is under cut-down BSD)
MSCHAPv2_fmt_plug.c             GPLv2; JoMo-Kun, magnum; code; there's a public domain statement by JoMo-Kun, but no statement by magnum, yet the license must be no more restrictive than GPLv2 because both authors directly contributed this code into 1.7+
Makefile                        GPLv2; various; code; there are no copyright-worthy changes left from pre-1.7 contributions by other than Solar, and GPLv2 is implied for post-1.7 contributions made directly by their authors
Makefile.dep                    N/A; none; empty
NETLM_fmt_plug.c                GPLv2; JoMo-Kun, magnum; code; same issue as with MSCHAPv2_fmt_plug.c
NETLMv2_fmt_plug.c              GPLv2; JoMo-Kun, magnum; code; same issue as with MSCHAPv2_fmt_plug.c
NETNTLM_fmt_plug.c              GPLv2; JoMo-Kun, magnum; code; same issue as with MSCHAPv2_fmt_plug.c
NETNTLMv2_fmt_plug.c            GPLv2; JoMo-Kun, magnum; code; same issue as with MSCHAPv2_fmt_plug.c
NETSPLITLM_fmt_plug.c           public domain; DSK, JoMo-Kun, magnum; code; same statement by magnum as in MSCHAPv2_fmt_plug.c, but it is followed by "Code is in public domain" further in the same comment
NS_fmt_plug.c                   public domain; Samuel Monux; code
NT_fmt_plug.c                   public domain + cut-down BSD fallback; Alain, magnum; code
PHPS_fmt_plug.c                 unclear; albert veli, regenrecht; code; contributed in 2007, so must be for 1.7+ and GPLv2 could be implied for that reason, but based on regenrecht's "salted IPB2 mode", which is of unclear licensing status (see IPB2_fmt_plug.c above)
PO_fmt_plug.c                   unclear; David Luyer et al.; code; "This file adapted from other code in this project" with no clarification which other files were used, David's copyright notice is from 2005, which is pre-1.7
SIPdump.c                       3-clause BSD; Martin J. Muench; code; comment refers to doc/SIPcrack-LICENSE
SIPdump.h                       3-clause BSD; Martin J. Muench; code; comment refers to doc/SIPcrack-LICENSE
SKEY_fmt.c                      3-clause BSD; Dug Song; code
SybaseASE_fmt.c                 cut-down BSD; James Nobis, Dhiru, magnum; code; the licensing statement is slightly ambiguous as it relates to Dhiru's and magnum's changes (Dhiru and magnum need to add themselves to the list of copyright holders)
UnicodeData.h                   public domain + cut-down BSD fallback; JimF; compile-time data; "manufactured from" UnicodeData.txt, which was presumably in the public domain (need to double-check), we might want to include the conversion code as a separate script (if we don't do that already), at least to be more obviously GPL-compatibile (must make available the source most appropriate for editing)
XSHA512_fmt.c                   GPLv2; Solar; code; contains minor changes by others (too minor for copyright)
XSHA_fmt_plug.c                 GPLv2; Solar, magnum; code; "Intrinsics support added by magnum 2011"
alghmac.h                       MPL 1.1 or GPLv2+; Netscape; code; dual-licensed
alpha.S                         GPLv2; Solar; code
alpha.h                         GPLv2; Solar; code
base64.c                        unclear; unclear; code; no copyright nor license statement on the file, it is unclear whether it was contributed by the author or by someone else, and when
base64.h                        N/A; unclear; code; too minor for copyright
batch.c                         GPLv2; Solar; code
batch.h                         GPLv2; Solar; code
bench.c                         GPLv2; Solar, JimF, magnum; code
bench.h                         GPLv2; Solar; code
best.c                          GPLv2; Solar; code
best.sh                         GPLv2; Solar; code
bf_tab.h                        N/A; unclear; compile-time data; not subject to copyright since the Blowfish S-boxes contain only digits of Pi
blowfish.c                      public domain?; unclear, Sun-Zero; code; one comments says that "this entire module will remain public domain", but another says "ripped from eggdrop 1.3.28's source files" (were they public domain?) and "Modified by Sun-Zero" (in 2002) without clarifying whether the prior public domain comment applied to the file before or after Sun-Zero's modifications
blowfish.h                      public domain; unclear; code; no explicit statement, but on one hand this is likely part of the public domain code referred to in blowfish.c and on the other data structure definitions are likely not copyrightable
byteorder.h                     GPLv2+; Andrew Tridgell; code
c3_fmt.c                        GPLv2; Solar, magnum; code; magnum added ability to benchmark other than descrypt hashes via this format
calc_stat.c                     GPLv2; bartavelle; code; GPLv2 is implied since the author contributed this for 1.7+, but ideally we need explicit copyright and license statement, and one using cut-down BSD
charset.c                       GPLv2; Solar; code; the changes in jumbo by other authors are very minor (support for building with MSVC, anything else?), so not subject to copyright
charset.h                       GPLv2; Solar; code
common-opencl.c                 GPLv2; unclear; code; was contributed by authors for 1.7+, hence GPLv2 is implied
common-opencl.h                 GPLv2; unclear; code; was contributed by authors for 1.7+, hence GPLv2 is implied
common.c                        GPLv2; Solar; code
common.h                        GPLv2; Solar; code; the only change in jumbo is addition of is_aligned() macro, which is too minor for copyright
common_opencl_pbkdf2.c          cut-down BSD; Sayantan; code
common_opencl_pbkdf2.h          cut-down BSD; Sayantan; code
compiler.c                      GPLv2; Solar; code
compiler.h                      GPLv2; Solar; code
config.c                        GPLv2; Solar, magnum; code; additions in jumbo for "include" directive support and printing of section names

detect.c                        GPLv2; Solar; code; the check for compiler macros implying x86 has been expanded in jumbo by JimF, but this is too minor for copyright

episerver_fmt.c                 cut-down BSD; Dhiru, JimF, magnum; code; we need explicit copyright statements from JimF and magnum
external.c                      GPLv2; Solar, magnum; code; MPI support and ext_has_function() by magnum
external.h                      GPLv2; Solar, magnum; code; ext_has_function() added by magnum
fake_salts.c                    public domain + cut-down BSD fallback; JimF; code
formats.c                       GPLv2; Solar, JimF, magnum; code; minor changes in jumbo for limiting max_keys_per_crypt (by magnum?) and for formats interface changes (by JimF), although the latter should be gone for 1.8+
formats.h                       GPLv2; Solar, JimF; code; minor additions in jumbo for Unicode support and formats interface changes, although the latter should be gone for 1.8+

gost.h                          cut-down MIT?; Aleksey Kravchenko?; code; was taken from rhash, so is probably under cut-down MIT license just like gost_plug.c, but we need to double-check and include specific copyright and license, although data structures, etc. might not be subject to copyright
gost_fmt_plug.c                 cut-down BSD; Dhiru, Sergey V., JimF; code
gost_plug.c                     cut-down MIT; Aleksey Kravchenko; code; the cut-down MIT license is relaxed to the point of being copyright-only with no restrictions, similarly to how our cut-down BSD is

idle.c                          GPLv2; Solar; code; minor changes in jumbo (by JimF?) for building with MSVC and MinGW, too minor for copyright

inc.c                           GPLv2; Solar, JoMo-Kun, Ryan Lim, magnum; code; changes in jumbo include MPI support, progress indicator, special handling of NETLM and NETHALFLM (use the LanMan section by default)

john-mpi.c                      GPL; Ryan Lim, magnum?; code; no copyright and license statement on the file, but doc/LICENSE.mpi and doc/README.mpi apply, GPL version is unclear
john-mpi.h                      GPL; Ryan Lim, magnum?; code; no copyright and license statement on the file, but doc/LICENSE.mpi and doc/README.mpi appl
y, GPL version is unclear

john.c                          GPLv2; Solar, magnum, JimF, others?; code
john.com                        GPLv2; Solar; code; compiled from john.asm
johnswap.h                      GPLv2; JimF?; code; no copyright and license statement, but was contributed by the author(?) for 1.7+, so GPLv2 is implied
keepass2john.c                  GPLv3+?; Dhiru, Karsten-Kai Koenig; code; Dhiru specified the license for his code as "GPL" without clarifying GPL version, "KeePass 2.x support is based on KeeCracker" and is under unclear license (unclear from the comment on this file), "KeePass 1.x support is based on kppy", which is under GPLv3+, and thus incompatible with JtR's licensing under GPLv2 - we might have to drop this file
keepass_fmt.c                   cut-down BSD; Dhiru; code
keychain2john.c                 cut-down BSD combined with another freeish license; Dhiru, Matt Johnston; code; the license by Matt says only "This code may be freely used and modified for any purpose", which unfortunately does not explicitly allow redistribution, let alone in binary and/or modified form - it would be nice to get that corrected (contact Matt or rewrite the code - in fact, it is so minor that there might not be much or any of the original code left already)
keychain_fmt_plug.c             cut-down BSD combined with another freeish license; Dhiru, Matt Johnston; code; same licensing issue as above, and it is similarly unclear what if anything is left from Matt's original
list.c                          GPLv2; Solar; code
list.h                          GPLv2; Solar; code

mozilla2john.c                  unclear; Dhiru?; code; if this file was written from scratch specifically for JtR 1.7+, then GPLv2 is implied, but without a copyright statement it is unclear who its author is

mscash2_fmt_plug.c              public domain + cut-down BSD fallback; S3nf, magnum, JimF; code; need to clarify that JimF's changes fall under the same terms, need to clarify that "This module is based on [...] the HMAC-SHA1 implementation of the PolarSSL open source cryptagraphic library" is not meant literally or at least that there's no longer any code from PolarSSL in this file

mssql05_fmt_plug.c              cut-down BSD or GPLv2?; bartavelle, Mathieu Perrin, magnum; code; the file uses our usual cut-down BSD license, but it also has "Modified by Mathieu Perrin (mathieu at tpfh.org) 09/06" with no license statement for Mathieu's changes (also 09/06 is inconsistent with bartavelle's copyright being 2010 only) - yet since even September 2006 (under worst possible interpretation) is JtR 1.7 days and all contributions were directly by their authors specifically for JtR, this implies no worse than GPLv2
mysqlSHA1_fmt_plug.c            cut-down BSD or GPLv2?; Marti Raudsepp, magnum; code; there's no license specified for Marti, but it's a 2007 contribution, so 1.7+ and GPLv2, magnum's change is "Use of SSE2 intrinsics" and it is under cut-down BSD, possibly not leaving much of the original file left (the file is small)
mysql_fmt_plug.c                GPLv2; Bucsay Balazs, Peter Kasza?, Solar; code; no explicit license and it is unclear if Peter contributed code or merely suggested that "Unbelievable good optimization", but since it's 2008 and contributions specifically for JtR 1.7+, GPLv2 is implied

nsldap_fmt_plug.c               unclear (maybe cut-down BSD); magnum; code; has cut-down BSD license on it, yet is "based on NSLDAP_fmt.c and rawSHA1_fmt.c", which might not (have been) compatible with that - how much is left from there, and who are the authors?
nt2_fmt_plug.c                  cut-down BSD; magnum, bartavelle?; code; has cut-down BSD license on it, yet is "Losely based on rawSHA1, by bartavelle" (how loosely? if not as loosely as to obviously not be subject to bartavelle's copyright, then we'd better add such copyright statement and include bartavelle's work under same license - with permission, of course)

oracle_fmt_plug.c               unclear; bartavelle, magnum; code; no license statement for bartavelle's code (and it's 2004, so pre-1.7), "UTF-8 support" is by magnum and under cut-down BSD

unicode.c                       GPLv2+ and Unicode license; Andrew Tridgell, Jeremy Allison, unspecified others, Unicode, magnum; code; Unicode's freeish license is potentially GPL-incompatible (imposes an extra restriction - requires that their disclaimer be included with each copy - whereas the GPL doesn't permit extra restrictions)

unrar.c                         unRAR license; Alexander L. Roshal, trog, magnum; code; the unRAR license may be GPL-incompatible (disallows "to re-create the RAR compression algorithm" and requires that "it is clearly stated in the documentation and source comments that the code may not be used to develop a RAR (WinRAR) compatible archiver"), so we may have to drop this

vnc_fmt_plug.c                  GPLv2; Dhiru, Jack Lloyd; code; GPL'ed because VNCcrack was, although doesn't use much (any?) code from it (and the data table is not copyrightable)

win32_memmap.c                  GPLv2; JimF?; code; no copyright and license statement, but GPLv2 is implied due to use from wordlist.c as contributed into 1.7+
win32_memmap.h                  GPLv2; JimF?; code; no copyright and license statement, but GPLv2 is implied due to use from wordlist.c as contributed into 1.7+
wordlist.c                      GPLv2; Solar, JimF, magnum; code; jumbo adds memory buffer, elimination of duplicates, loopback mode, MPI support, progress indicator

wpapsk.h                        cut-down BSD?; Lukas; code; file has our cut-down BSD license, but also says "Code is based on  Aircrack-ng source", which is likely licensed under more restrictive terms, however the file doesn't appear to actually use much or anything from Aircrack-ng - need to check and correct the statement
wpapsk_fmt.c                    cut-down BSD?; Lukas; code; same issue as with wpapsk.h
x86-64.S                        cut-down BSD; Solar, Alain; code; Solar's code is under cut-down BSD, Alain's is public domain + cut-down BSD fallback
