GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 2.1, February 1999
|
||||
|
||||
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
[This is the first released version of the Lesser GPL. It also counts
|
||||
as the successor of the GNU Library Public License, version 2, hence
|
||||
the version number 2.1.]
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
Licenses are intended to guarantee your freedom to share and change
|
||||
free software--to make sure the software is free for all its users.
|
||||
|
||||
This license, the Lesser General Public License, applies to some
|
||||
specially designated software packages--typically libraries--of the
|
||||
Free Software Foundation and other authors who decide to use it. You
|
||||
can use it too, but we suggest you first think carefully about whether
|
||||
this license or the ordinary General Public License is the better
|
||||
strategy to use in any particular case, based on the explanations below.
|
||||
|
||||
When we speak of free software, we are referring to freedom of use,
|
||||
not price. Our General Public Licenses are designed to make sure that
|
||||
you have the freedom to distribute copies of free software (and charge
|
||||
for this service if you wish); that you receive source code or can get
|
||||
it if you want it; that you can change the software and use pieces of
|
||||
it in new free programs; and that you are informed that you can do
|
||||
these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
distributors to deny you these rights or to ask you to surrender these
|
||||
rights. These restrictions translate to certain responsibilities for
|
||||
you if you distribute copies of the library or if you modify it.
|
||||
|
||||
For example, if you distribute copies of the library, whether gratis
|
||||
or for a fee, you must give the recipients all the rights that we gave
|
||||
you. You must make sure that they, too, receive or can get the source
|
||||
code. If you link other code with the library, you must provide
|
||||
complete object files to the recipients, so that they can relink them
|
||||
with the library after making changes to the library and recompiling
|
||||
it. And you must show them these terms so they know their rights.
|
||||
|
||||
We protect your rights with a two-step method: (1) we copyright the
|
||||
library, and (2) we offer you this license, which gives you legal
|
||||
permission to copy, distribute and/or modify the library.
|
||||
|
||||
To protect each distributor, we want to make it very clear that
|
||||
there is no warranty for the free library. Also, if the library is
|
||||
modified by someone else and passed on, the recipients should know
|
||||
that what they have is not the original version, so that the original
|
||||
author's reputation will not be affected by problems that might be
|
||||
introduced by others.
|
||||
|
||||
Finally, software patents pose a constant threat to the existence of
|
||||
any free program. We wish to make sure that a company cannot
|
||||
effectively restrict the users of a free program by obtaining a
|
||||
restrictive license from a patent holder. Therefore, we insist that
|
||||
any patent license obtained for a version of the library must be
|
||||
consistent with the full freedom of use specified in this license.
|
||||
|
||||
Most GNU software, including some libraries, is covered by the
|
||||
ordinary GNU General Public License. This license, the GNU Lesser
|
||||
General Public License, applies to certain designated libraries, and
|
||||
is quite different from the ordinary General Public License. We use
|
||||
this license for certain libraries in order to permit linking those
|
||||
libraries into non-free programs.
|
||||
|
||||
When a program is linked with a library, whether statically or using
|
||||
a shared library, the combination of the two is legally speaking a
|
||||
combined work, a derivative of the original library. The ordinary
|
||||
General Public License therefore permits such linking only if the
|
||||
entire combination fits its criteria of freedom. The Lesser General
|
||||
Public License permits more lax criteria for linking other code with
|
||||
the library.
|
||||
|
||||
We call this license the "Lesser" General Public License because it
|
||||
does Less to protect the user's freedom than the ordinary General
|
||||
Public License. It also provides other free software developers Less
|
||||
of an advantage over competing non-free programs. These disadvantages
|
||||
are the reason we use the ordinary General Public License for many
|
||||
libraries. However, the Lesser license provides advantages in certain
|
||||
special circumstances.
|
||||
|
||||
For example, on rare occasions, there may be a special need to
|
||||
encourage the widest possible use of a certain library, so that it becomes
|
||||
a de-facto standard. To achieve this, non-free programs must be
|
||||
allowed to use the library. A more frequent case is that a free
|
||||
library does the same job as widely used non-free libraries. In this
|
||||
case, there is little to gain by limiting the free library to free
|
||||
software only, so we use the Lesser General Public License.
|
||||
|
||||
In other cases, permission to use a particular library in non-free
|
||||
programs enables a greater number of people to use a large body of
|
||||
free software. For example, permission to use the GNU C Library in
|
||||
non-free programs enables many more people to use the whole GNU
|
||||
operating system, as well as its variant, the GNU/Linux operating
|
||||
system.
|
||||
|
||||
Although the Lesser General Public License is Less protective of the
|
||||
users' freedom, it does ensure that the user of a program that is
|
||||
linked with the Library has the freedom and the wherewithal to run
|
||||
that program using a modified version of the Library.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow. Pay close attention to the difference between a
|
||||
"work based on the library" and a "work that uses the library". The
|
||||
former contains code derived from the library, whereas the latter must
|
||||
be combined with the library in order to run.
|
||||
|
||||
GNU LESSER GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License Agreement applies to any software library or other
|
||||
program which contains a notice placed by the copyright holder or
|
||||
other authorized party saying it may be distributed under the terms of
|
||||
this Lesser General Public License (also called "this License").
|
||||
Each licensee is addressed as "you".
|
||||
|
||||
A "library" means a collection of software functions and/or data
|
||||
prepared so as to be conveniently linked with application programs
|
||||
(which use some of those functions and data) to form executables.
|
||||
|
||||
The "Library", below, refers to any such software library or work
|
||||
which has been distributed under these terms. A "work based on the
|
||||
Library" means either the Library or any derivative work under
|
||||
copyright law: that is to say, a work containing the Library or a
|
||||
portion of it, either verbatim or with modifications and/or translated
|
||||
straightforwardly into another language. (Hereinafter, translation is
|
||||
included without limitation in the term "modification".)
|
||||
|
||||
"Source code" for a work means the preferred form of the work for
|
||||
making modifications to it. For a library, complete source code means
|
||||
all the source code for all modules it contains, plus any associated
|
||||
interface definition files, plus the scripts used to control compilation
|
||||
and installation of the library.
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running a program using the Library is not restricted, and output from
|
||||
such a program is covered only if its contents constitute a work based
|
||||
on the Library (independent of the use of the Library in a tool for
|
||||
writing it). Whether that is true depends on what the Library does
|
||||
and what the program that uses the Library does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Library's
|
||||
complete source code as you receive it, in any medium, provided that
|
||||
you conspicuously and appropriately publish on each copy an
|
||||
appropriate copyright notice and disclaimer of warranty; keep intact
|
||||
all the notices that refer to this License and to the absence of any
|
||||
warranty; and distribute a copy of this License along with the
|
||||
Library.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy,
|
||||
and you may at your option offer warranty protection in exchange for a
|
||||
fee.
|
||||
|
||||
2. You may modify your copy or copies of the Library or any portion
|
||||
of it, thus forming a work based on the Library, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) The modified work must itself be a software library.
|
||||
|
||||
b) You must cause the files modified to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
c) You must cause the whole of the work to be licensed at no
|
||||
charge to all third parties under the terms of this License.
|
||||
|
||||
d) If a facility in the modified Library refers to a function or a
|
||||
table of data to be supplied by an application program that uses
|
||||
the facility, other than as an argument passed when the facility
|
||||
is invoked, then you must make a good faith effort to ensure that,
|
||||
in the event an application does not supply such function or
|
||||
table, the facility still operates, and performs whatever part of
|
||||
its purpose remains meaningful.
|
||||
|
||||
(For example, a function in a library to compute square roots has
|
||||
a purpose that is entirely well-defined independent of the
|
||||
application. Therefore, Subsection 2d requires that any
|
||||
application-supplied function or table used by this function must
|
||||
be optional: if the application does not supply it, the square
|
||||
root function must still compute square roots.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Library,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Library, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote
|
||||
it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Library.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Library
|
||||
with the Library (or with a work based on the Library) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
||||
License instead of this License to a given copy of the Library. To do
|
||||
this, you must alter all the notices that refer to this License, so
|
||||
that they refer to the ordinary GNU General Public License, version 2,
|
||||
instead of to this License. (If a newer version than version 2 of the
|
||||
ordinary GNU General Public License has appeared, then you can specify
|
||||
that version instead if you wish.) Do not make any other change in
|
||||
these notices.
|
||||
|
||||
Once this change is made in a given copy, it is irreversible for
|
||||
that copy, so the ordinary GNU General Public License applies to all
|
||||
subsequent copies and derivative works made from that copy.
|
||||
|
||||
This option is useful when you wish to copy part of the code of
|
||||
the Library into a program that is not a library.
|
||||
|
||||
4. You may copy and distribute the Library (or a portion or
|
||||
derivative of it, under Section 2) in object code or executable form
|
||||
under the terms of Sections 1 and 2 above provided that you accompany
|
||||
it with the complete corresponding machine-readable source code, which
|
||||
must be distributed under the terms of Sections 1 and 2 above on a
|
||||
medium customarily used for software interchange.
|
||||
|
||||
If distribution of object code is made by offering access to copy
|
||||
from a designated place, then offering equivalent access to copy the
|
||||
source code from the same place satisfies the requirement to
|
||||
distribute the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
5. A program that contains no derivative of any portion of the
|
||||
Library, but is designed to work with the Library by being compiled or
|
||||
linked with it, is called a "work that uses the Library". Such a
|
||||
work, in isolation, is not a derivative work of the Library, and
|
||||
therefore falls outside the scope of this License.
|
||||
|
||||
However, linking a "work that uses the Library" with the Library
|
||||
creates an executable that is a derivative of the Library (because it
|
||||
contains portions of the Library), rather than a "work that uses the
|
||||
library". The executable is therefore covered by this License.
|
||||
Section 6 states terms for distribution of such executables.
|
||||
|
||||
When a "work that uses the Library" uses material from a header file
|
||||
that is part of the Library, the object code for the work may be a
|
||||
derivative work of the Library even though the source code is not.
|
||||
Whether this is true is especially significant if the work can be
|
||||
linked without the Library, or if the work is itself a library. The
|
||||
threshold for this to be true is not precisely defined by law.
|
||||
|
||||
If such an object file uses only numerical parameters, data
|
||||
structure layouts and accessors, and small macros and small inline
|
||||
functions (ten lines or less in length), then the use of the object
|
||||
file is unrestricted, regardless of whether it is legally a derivative
|
||||
work. (Executables containing this object code plus portions of the
|
||||
Library will still fall under Section 6.)
|
||||
|
||||
Otherwise, if the work is a derivative of the Library, you may
|
||||
distribute the object code for the work under the terms of Section 6.
|
||||
Any executables containing that work also fall under Section 6,
|
||||
whether or not they are linked directly with the Library itself.
|
||||
|
||||
6. As an exception to the Sections above, you may also combine or
|
||||
link a "work that uses the Library" with the Library to produce a
|
||||
work containing portions of the Library, and distribute that work
|
||||
under terms of your choice, provided that the terms permit
|
||||
modification of the work for the customer's own use and reverse
|
||||
engineering for debugging such modifications.
|
||||
|
||||
You must give prominent notice with each copy of the work that the
|
||||
Library is used in it and that the Library and its use are covered by
|
||||
this License. You must supply a copy of this License. If the work
|
||||
during execution displays copyright notices, you must include the
|
||||
copyright notice for the Library among them, as well as a reference
|
||||
directing the user to the copy of this License. Also, you must do one
|
||||
of these things:
|
||||
|
||||
a) Accompany the work with the complete corresponding
|
||||
machine-readable source code for the Library including whatever
|
||||
changes were used in the work (which must be distributed under
|
||||
Sections 1 and 2 above); and, if the work is an executable linked
|
||||
with the Library, with the complete machine-readable "work that
|
||||
uses the Library", as object code and/or source code, so that the
|
||||
user can modify the Library and then relink to produce a modified
|
||||
executable containing the modified Library. (It is understood
|
||||
that the user who changes the contents of definitions files in the
|
||||
Library will not necessarily be able to recompile the application
|
||||
to use the modified definitions.)
|
||||
|
||||
b) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (1) uses at run time a
|
||||
copy of the library already present on the user's computer system,
|
||||
rather than copying library functions into the executable, and (2)
|
||||
will operate properly with a modified version of the library, if
|
||||
the user installs one, as long as the modified version is
|
||||
interface-compatible with the version that the work was made with.
|
||||
|
||||
c) Accompany the work with a written offer, valid for at
|
||||
least three years, to give the same user the materials
|
||||
specified in Subsection 6a, above, for a charge no more
|
||||
than the cost of performing this distribution.
|
||||
|
||||
d) If distribution of the work is made by offering access to copy
|
||||
from a designated place, offer equivalent access to copy the above
|
||||
specified materials from the same place.
|
||||
|
||||
e) Verify that the user has already received a copy of these
|
||||
materials or that you have already sent this user a copy.
|
||||
|
||||
For an executable, the required form of the "work that uses the
|
||||
Library" must include any data and utility programs needed for
|
||||
reproducing the executable from it. However, as a special exception,
|
||||
the materials to be distributed need not include anything that is
|
||||
normally distributed (in either source or binary form) with the major
|
||||
components (compiler, kernel, and so on) of the operating system on
|
||||
which the executable runs, unless that component itself accompanies
|
||||
the executable.
|
||||
|
||||
It may happen that this requirement contradicts the license
|
||||
restrictions of other proprietary libraries that do not normally
|
||||
accompany the operating system. Such a contradiction means you cannot
|
||||
use both them and the Library together in an executable that you
|
||||
distribute.
|
||||
|
||||
7. You may place library facilities that are a work based on the
|
||||
Library side-by-side in a single library together with other library
|
||||
facilities not covered by this License, and distribute such a combined
|
||||
library, provided that the separate distribution of the work based on
|
||||
the Library and of the other library facilities is otherwise
|
||||
permitted, and provided that you do these two things:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work
|
||||
based on the Library, uncombined with any other library
|
||||
facilities. This must be distributed under the terms of the
|
||||
Sections above.
|
||||
|
||||
b) Give prominent notice with the combined library of the fact
|
||||
that part of it is a work based on the Library, and explaining
|
||||
where to find the accompanying uncombined form of the same work.
|
||||
|
||||
8. You may not copy, modify, sublicense, link with, or distribute
|
||||
the Library except as expressly provided under this License. Any
|
||||
attempt otherwise to copy, modify, sublicense, link with, or
|
||||
distribute the Library is void, and will automatically terminate your
|
||||
rights under this License. However, parties who have received copies,
|
||||
or rights, from you under this License will not have their licenses
|
||||
terminated so long as such parties remain in full compliance.
|
||||
|
||||
9. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Library or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Library (or any work based on the
|
||||
Library), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Library or works based on it.
|
||||
|
||||
10. Each time you redistribute the Library (or any work based on the
|
||||
Library), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute, link with or modify the Library
|
||||
subject to these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties with
|
||||
this License.
|
||||
|
||||
11. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Library at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Library by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Library.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under any
|
||||
particular circumstance, the balance of the section is intended to apply,
|
||||
and the section as a whole is intended to apply in other circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
12. If the distribution and/or use of the Library is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Library under this License may add
|
||||
an explicit geographical distribution limitation excluding those countries,
|
||||
so that distribution is permitted only in or among countries not thus
|
||||
excluded. In such case, this License incorporates the limitation as if
|
||||
written in the body of this License.
|
||||
|
||||
13. The Free Software Foundation may publish revised and/or new
|
||||
versions of the Lesser General Public License from time to time.
|
||||
Such new versions will be similar in spirit to the present version,
|
||||
but may differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Library
|
||||
specifies a version number of this License which applies to it and
|
||||
"any later version", you have the option of following the terms and
|
||||
conditions either of that version or of any later version published by
|
||||
the Free Software Foundation. If the Library does not specify a
|
||||
license version number, you may choose any version ever published by
|
||||
the Free Software Foundation.
|
||||
|
||||
14. If you wish to incorporate parts of the Library into other free
|
||||
programs whose distribution conditions are incompatible with these,
|
||||
write to the author to ask for permission. For software which is
|
||||
copyrighted by the Free Software Foundation, write to the Free
|
||||
Software Foundation; we sometimes make exceptions for this. Our
|
||||
decision will be guided by the two goals of preserving the free status
|
||||
of all derivatives of our free software and of promoting the sharing
|
||||
and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
||||
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
||||
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
||||
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
||||
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
||||
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
||||
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
||||
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
||||
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
||||
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
||||
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
||||
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
||||
DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Libraries
|
||||
|
||||
If you develop a new library, and you want it to be of the greatest
|
||||
possible use to the public, we recommend making it free software that
|
||||
everyone can redistribute and change. You can do so by permitting
|
||||
redistribution under these terms (or, alternatively, under the terms of the
|
||||
ordinary General Public License).
|
||||
|
||||
To apply these terms, attach the following notices to the library. It is
|
||||
safest to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least the
|
||||
"copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the library's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||

|
||||

|
||||

|
||||

This library is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
||||

|
||||
|

You should have received a copy of the GNU Lesser General Public

|
||||

|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the library, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||

|
||||
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

User-visible changes in udns library. Recent changes on top.
|
||||
|
||||
0.4 (Jan 2014)
|
||||
|
||||
- bugfix: fix a bug in new list code introduced in 0.3
|
||||
- portability: use $(LD)/$(LDFLAGS)/$(LIBS)
|
||||
|
||||
0.3 (Jan 2014)
|
||||
|
||||
- bugfix: refactor double-linked list implementation in udns_resolver.c
|
||||
(internal to the library) to be more strict-aliasing-friendly, because
|
||||
old code were miscompiled by gcc.
|
||||
|
||||
- bugfix: forgotten strdup() in rblcheck
|
||||
|
||||
0.2 (Dec 2011)
|
||||
|
||||
- bugfix: SRV RR handling: fix domain name parsing and crash in case
|
||||
if no port is specified on input for SRV record query
|
||||
|
||||
- (trivial api) dns_set_opts() now returns number of unrecognized
|
||||
options instead of always returning 0
|
||||
|
||||
- dnsget: combine -f and -o options in dnsget (and stop documenting -f),
|
||||
and report unknown/invalid -o options (and error out)
|
||||
|
||||
- dnsget: pretty-print SSHFP RRs
|
||||
|
||||
0.1 (Dec 2010)
|
||||
|
||||
- bugfix: udns_new(old) - when actually cloning another context -
|
||||
makes the new context referencing memory from old, which leads
|
||||
to crashes when old is modified later
|
||||
|
||||
- use random queue IDs (the 16bit qID) in queries instead of sequentional
|
||||
ones, based on simple pseudo-random RNG by Bob Jenkins (udns_jran.[ch]).
|
||||
Some people believe that this improves security (CVE-2008-1447). I'm
|
||||
still not convinced (see comments in udns_resolver.c), but it isn't
|
||||
difficult to add after all.
|
||||
|
||||
- deprecate dns_random16() function which was declared in udns.h
|
||||
(not anymore) but never documented. In order to keep ABI compatible
|
||||
it is still exported.
|
||||
|
||||
- library has a way now to set query flags (DNS_SET_DO; DNS_SET_CD).
|
||||
|
||||
- dnsget now prints non-printable chars in all strings in DNS RRs using
|
||||
decimal escape sequences (\%03u) instead of hexadecimal (\%02x) when
|
||||
before - other DNS software does it like this.
|
||||
|
||||
- recognize a few more record types in dnsget, notable some DNSSEC RRs;
|
||||
add -f option for dnsget to set query flags.
|
||||
|
||||
- udns is not a Debian native package anymore (was a wrong idea)
|
||||
|
||||
0.0.9 (16 Jan 2007)
|
||||
|
||||
- incompat: minor API changes in dns_init() &friends. dns_init()
|
||||
now requires extra `struct dns_ctx *' argument. Not bumped
|
||||
soversion yet - I only expect one "release" with this change.
|
||||
|
||||
- many small bugfixes, here and there
|
||||
|
||||
- more robust FORMERR replies handling - not only such replies are now
|
||||
recognized, but udns retries queries without EDNS0 extensions if tried
|
||||
with, but server reported FORMERR
|
||||
|
||||
- portability changes, udns now includes getopt() implementation fo
|
||||
the systems lacking it (mostly windows), and dns_ntop()&dns_pton(),
|
||||
which are either just wrappers for system functions or reimplementations.
|
||||
|
||||
- build is now based on autoconf-like configuration
|
||||
|
||||
- NAPTR (RFC3403) RR decoding support
|
||||
|
||||
- new file NOTES which complements TODO somewhat, and includes some
|
||||
important shortcomings
|
||||
|
||||
- many internal cleanups, including some preparations for better error
|
||||
recovery, security and robustness (and thus API changes)
|
||||
|
||||
- removed some #defines which are now unused (like DNS_MAXSRCH)
|
||||
|
||||
- changed WIN32 to WINDOWS everywhere in preprocessor tests,
|
||||
to be able to build it on win64 as well
|
||||
|
||||
0.0.8 (12 Sep 2005)
|
||||
|
||||
- added SRV records (rfc2782) parsing,
|
||||
thanks to Thadeu Lima de Souza Cascardo for implementation.
|
||||
|
||||
- bugfixes:
|
||||
o use uninitialized value when no reply, library died with assertion:

- rblcheck(.1)
|
||||
|
||||
0.0.7 (20 Apr 2005)
|
||||
|
||||
- dnsget.1 manpage and several enhancements to dnsget.
|
||||
|
||||
- allow nameserver names for -n option of dnsget.
|
||||
|
||||
- API change: all dns_submit*() routines now does not expect
|
||||
last `now' argument, since requests aren't sent immediately
|
||||
anymore.
|
||||
|
||||
- API change: different application timer callback mechanism.
|
||||
Udns now uses single per-context timer instead of per-query.
|
||||
|
||||
- don't assume DNS replies only contain backward DN pointers,
|
||||
allow forward pointers too. Change parsing API.
|
||||
|
||||
- debianize
|
||||
|
||||
0.0.6 (08 Apr 2005)
|
||||
|
||||
- use double sorted list for requests (sorted by deadline).
|
||||
This should significantly speed up timeout processing for
|
||||
large number of requests.
|
||||
|
||||
- changed debugging interface, so it is finally useable
|
||||
(still not documented).
|
||||
|
||||
- dnsget routine is now Officially Useable, and sometimes
|
||||
even more useable than `host' from BIND distribution
|
||||
(and sometimes not - dnsget does not have -C option
|
||||
and TCP mode)
|
||||
|
||||
- Debian packaging in debian/ -- udns is now maintained as a
|
||||
native Debian package.
|
||||
|
||||
- alot (and I really mean alot) of code cleanups all over.

Assorted notes about udns (library).
|
||||
|
||||
UDP-only mode
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
First of all, since udns is (currently) UDP-only, there are some
|
||||
shortcomings.
|
||||
|
||||
It assumes that a reply will fit into a UDP buffer. With adoption of EDNS0,
|
||||
and general robustness of IP stacks, in most cases it's not an issue. But
|
||||
in some cases there may be problems:
|
||||
|
||||
- if an RRset is "very large" so it does not fit even in buffer of size
|
||||
requested by the library (current default is 4096; some servers limits
|
||||
it further), we will not see the reply, or will only see "damaged"
|
||||
reply (depending on the server).
|
||||
|
||||
- many DNS servers ignores EDNS0 option requests. In this case, no matter
|
||||
which buffer size udns library will request, such servers reply is limited
|
||||
to 512 bytes (standard pre-EDNS0 DNS packet size). (Udns falls back to
|
||||
non-EDNO0 query if EDNS0-enabled one received FORMERR or NOTIMPL error).
|
||||
|
||||
The problem is that with this, udns currently will not consider replies with
|
||||
TC (truncation) bit set, and will treat such replies the same way as it
|
||||
treats SERVFAIL replies, thus trying next server, or temp-failing the query
|
||||
if no more servers to try. In other words, if the reply is really large, or
|
||||
if the servers you're using don't support EDNS0, your application will be
|
||||
unable to resolve a given name.
|
||||
|
||||
Yet it's not common situation - in practice, it's very rare.
|
||||
|
||||
Implementing TCP mode isn't difficult, but it complicates API significantly.
|
||||
Currently udns uses only single UDP socket (or - maybe in the future - two,
|
||||
see below), but in case of TCP, it will need to open and close sockets for
|
||||
TCP connections left and right, and that have to be integrated into an
|
||||
application's event loop in an easy and efficient way. Plus all the
|
||||
timeouts - different for connect(), write, and several stages of read.
|
||||
|
||||
IPv6 vs IPv4 usage
|
||||
~~~~~~~~~~~~~~~~~~
|
||||
|
||||
This is only relevant for nameservers reachable over IPv6, NOT for IPv6
|
||||
queries. I.e., if you've IPv6 addresses in 'nameservers' line in your
|
||||
/etc/resolv.conf file. Even more: if you have BOTH IPv6 AND IPv4 addresses
|
||||
there. Or pass them to udns initialization routines.
|
||||
|
||||
Since udns uses a single UDP socket to communicate with all nameservers,
|
||||
it should support both v4 and v6 communications. Most current platforms
|
||||
supports this mode - using PF_INET6 socket and V4MAPPED addresses, i.e,
|
||||
"tunnelling" IPv4 inside IPv6. But not all systems supports this. And
|
||||
more, it has been said that such mode is deprecated.
|
||||
|
||||
So, list only IPv4 or only IPv6 addresses, but don't mix them, in your
|
||||
/etc/resolv.conf.
|
||||
|
||||
An alternative is to use two sockets instead of 1 - one for IPv6 and one
|
||||
for IPv4. For now I'm not sure if it's worth the complexity - again, of
|
||||
the API, not the library itself (but this will not simplify library either).
|
||||
|
||||
Single socket for all queries
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Using single UDP socket for sending queries to all nameservers has obvious
|
||||
advantages. First it's, again, trivial, simple to use API. And simple
|
||||
library too. Also, after sending queries to all nameservers (in case first
|
||||
didn't reply in time), we will be able to receive late reply from first
|
||||
nameserver and accept it.
|
||||
|
||||
But this mode has disadvantages too. Most important is that it's much easier
|
||||
to send fake reply to us, as the UDP port where we expects the reply to come
|
||||
to is constant during the whole lifetime of an application. More secure
|
||||
implementations uses random port for every single query. While port number
|
||||
(16 bits integer) can not hold much randomness, it's still of some help.
|
||||
Ok, udns is a stub resolver, so it expects sorta friendly environment, but
|
||||
on LAN it's usually much easier to fire an attack, due to the speed of local
|
||||
network, where a bad guy can generate alot of packets in a short time.
|
||||
|
||||
Spoofing of replies (Kaminsky attack, CVE-2008-1447)
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
While udns uses random numbers for query IDs, it uses single UDP port for
|
||||
all queries (see previous item). And even if it used random UDP port for
|
||||
each query, the attack described in CVE-2008-1447 is still quite trivial.
|
||||
This is not specific to udns library unfortunately - it is inherent property
|
||||
of the protocol. Udns is designed to work in a LAN, it needs full recursive
|
||||
resolver nearby, and modern LAN usually uses high-bandwidth equipment which
|
||||
makes the Kaminsky attack trivial. The problem is that even with qID (16
|
||||
bits) and random UDP port (about 20 bits available to a regular process)
|
||||
combined still can not hold enough randomness, so on a fast network it is
|
||||
still easy to flood the target with fake replies and hit the "right" reply
|
||||
before real reply comes. So random qIDs don't add much protection anyway,
|
||||
even if this feature is implemented in udns, and using all available
|
||||
techniques wont solve it either.
|
||||
|
||||
See also long comment in udns_resolver.c, udns_newid().
|
||||
|
||||
Assumptions about RRs returned
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Currently udns processes records in the reply it received sequentially.
|
||||
This means that order of the records is significant. For example, if
|
||||
we asked for foo.bar A, but the server returned that foo.bar is a CNAME
|
||||
(alias) for bar.baz, and bar.baz, in turn, has address 1.2.3.4, when
|
||||
the CNAME should come first in reply, followed by A. While DNS specs
|
||||
does not say anything about order of records - it's an rrSET - unordered, -
|
||||
I think an implementation which returns the records in "wrong" order is
|
||||
somewhat insane...
|
||||
|
||||
CNAME recursion
|
||||
~~~~~~~~~~~~~~~
|
||||
|
||||
Another interesting point is the handling of CNAMEs returned as replies
|
||||
to non-CNAME queries. If we asked for foo.bar A, but it's a CNAME, udns
|
||||
expects BOTH the CNAME itself and the target DN to be present in the reply.
|
||||
In other words, udns DOES NOT RECURSE CNAMES. If we asked for foo.bar A,
|
||||
but only record in reply was that foo.bar is a CNAME for bar.baz, udns will
|
||||
return no records to an application (NXDOMAIN). Strictly speaking, udns
|
||||
should repeat the query asking for bar.baz A, and recurse. But since it's
|
||||
stub resolver, recursive resolver should recurse for us instead.
|
||||
|
||||
It's not very difficult to implement, however. Probably with some (global?)
|
||||
flag to en/dis-able the feature. Provided there's some demand for it.
|
||||
|
||||
To clarify: udns handles CNAME recursion in a single reply packet just fine.
|
||||
|
||||
Note also that standard gethostbyname() routine does not recurse in this
|
||||
situation, too.
|
||||
|
||||
Error reporting
|
||||
~~~~~~~~~~~~~~~
|
||||
|
||||
Too many places in the code (various failure paths) sets generic "TEMPFAIL"
|
||||
error condition. For example, if no nameserver replied to our query, an
|
||||
application will get generic TEMPFAIL, instead of something like TIMEDOUT.
|
||||
This probably should be fixed, but most applications don't care about the
|
||||
exact reasons of failure - 4 common cases are already too much:
|
||||
- query returned some valid data
|
||||
- NXDOMAIN
|
||||
- valid domain but no data of requested type - =NXDOMAIN in most cases
|
||||
- temporary error - this one sometimes (incorrectly!) treated as NXDOMAIN
|
||||
by (naive) applications.
|
||||
DNS isn't yes/no, it's at least 3 variants, temp err being the 3rd important
|
||||
case! And adding more variations for the temp error case is complicating things
|
||||
even more - again, from an application writer standpoint. For diagnostics,
|
||||
such more specific error cases are of good help.
|
||||
|
||||
Planned API changes
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
At least one thing I want to change for some future version is a way how
|
||||
queries are submitted and how replies are handled.
|
||||
|
||||
I want to made dns_query object to be owned by an application. So that instead
|
||||
of udns library allocating it for the lifetime of query, it will be pre-
|
||||
allocated by an application. This simplifies and enhances query submitting
|
||||
interface, and complicates it a bit too, in simplest cases.
|
||||
|
||||
Currently, we have:
|
||||
|
||||
dns_submit_dn(dn, cls, typ, flags, parse, cbck, data)
|
||||
dns_submit_p(name, cls, typ, flags, parse, cbck, data)
|
||||
dns_submit_a4(ctx, name, flags, cbck, data)
|
||||
|
||||
and so on -- with many parameters missed for type-specific cases, but generic
|
||||
cases being too complex for most common usage.
|
||||
|
||||
Instead, with dns_query being owned by an app, we will be able to separately
|
||||
set up various parts of the query - domain name (various forms), type&class,
|
||||
parser, flags, callback... and even change them at runtime. And we will also
|
||||
be able to reuse query structures, instead of allocating/freeing them every
|
||||
time. So the whole thing will look something like:
|
||||
|
||||
q = dns_alloc_query();
|
||||
dns_submit(dns_q_flags(dns_q_a4(q, name, cbck), DNS_F_NOSRCH), data);
|
||||
|
||||
The idea is to have a set of functions accepting struct dns_query* and
|
||||
returning it (so the calls can be "nested" like the above), to set up
|
||||
relevant parts of the query - specific type of callback, conversion from
|
||||
(type-specific) query parameters into a domain name (this is for type-
|
||||
specific query initializers), and setting various flags and options and
|
||||
type&class things.
|
||||
|
||||
One example where this is almost essential - if we want to support
|
||||
per-query set of nameservers (which isn't at all useless: imagine a
|
||||
high-volume mail server, were we want to direct DNSBL queries to a separate
|
||||
set of nameservers, and rDNS queries to their own set and so on). Adding
|
||||
another argument (set of nameservers to use) to EVERY query submitting
|
||||
routine is.. insane. Especially since in 99% cases it will be set to
|
||||
default NULL. But with such "nesting" of query initializers, it becomes
|
||||
trivial.
|
||||
|
||||
This change (the way how queries gets submitted) will NOT break API/ABI
|
||||
compatibility with old versions, since the new submitting API works in
|
||||
parallel with current (and current will use the new one as building
|
||||
blocks, instead of doing all work at once).
|
||||
|
||||
Another way to do the same is to manipulate query object right after a
|
||||
query has been submitted, but before any events processing (during this
|
||||
time, query object is allocated and initialized, but no actual network
|
||||
packets were sent - it will happen on the next event processing). But
|
||||
this way it become impossible to perform syncronous resolver calls, since
|
||||
those calls hide query objects they use internally.
|
||||
|
||||
Speaking of replies handling - the planned change is to stop using dynamic
|
||||
memory (malloc) inside the library. That is, instead of allocating a buffer
|
||||
for a reply dynamically in a parsing routine (or memdup'ing the raw reply
|
||||
packet if no parsing routine is specified), I want udns to return the packet
|
||||
buffer it uses internally, and change parsing routines to expect a buffer
|
||||
for result. When parsing, a routine will return true amount of memory it
|
||||
will need to place the result, regardless of whenever it has enough room
|
||||
or not, so that an application can (re)allocate properly sized buffer and
|
||||
call a parsing routine again.
|
||||
|
||||
This, in theory, also can be done without breaking current API/ABI, but in
|
||||
that case we'll again need a parallel set of routines (parsing included),
|
||||
which makes the library more complicated with too many ways of doing the
|
||||
same thing. Still, code reuse is at good level.
|
||||
|
||||
Another modification I plan to include is to have an ability to work in
|
||||
terms of domain names (DNs) as used with on-wire DNS packets, not only
|
||||
with asciiz representations of them. For this to work, the above two
|
||||
changes (query submission and result passing) have to be completed first
|
||||
(esp. the query submission part), so that it will be possible to specify
|
||||
some additional query flags (for example) to request domain names instead
|
||||
of the text strings, and to allow easy query submissions with either DNs
|
||||
or text strings.

|

TODO
|
||||
|
||||
The following is mostly an internal, not user-visible stuff.
|
||||
|
||||
* rearrange an API to make dns_query object owned by application,
|
||||
so that it'll look like this:
|
||||
struct dns_query *q;
|
||||
q = dns_query_alloc(ctx);
|
||||
dns_query_set(q, options, domain_name, flags, ...);
|
||||
dns_query_submit(ctx, q);
|
||||
For more information see NOTES file, section "Planned API changes".
|
||||
|
||||
* allow NULL callbacks? Or provide separate resolver
|
||||
context list of queries which are done but wich did not
|
||||
have callback, and dns_pick() routine to retrieve results
|
||||
from this query, i.e. allow non-callback usage? The
|
||||
non-callback usage may be handy sometimes (any *good*
|
||||
example?), but it will be difficult to provide type-safe
|
||||
non-callback interface due to various RR-specific types
|
||||
in use.
|
||||
|
||||
* DNS_OPT_FLAGS should be DNS_OPT_ADDFLAGS and DNS_OPT_SETFLAGS.
|
||||
Currently one can't add a single flag bit but preserve
|
||||
existing bits... at least not without retrieving all current
|
||||
flags before, which isn't that bad anyway.
|
||||
|
||||
* dns_set_opts() may process flags too (such as aaonly etc)
|
||||
|
||||
* a way to disable $NSCACHEIP et al processing?
|
||||
(with now separate dns_init() and dns_reset(), it has finer
|
||||
control, but still no way to init from system files but ignore
|
||||
environment variables and the like)
|
||||
|
||||
* initialize/open the context automatically, and be more
|
||||
liberal about initialization in general?
|
||||
|
||||
* dns_init(ctx, do_open) - make the parameter opposite, aka
|
||||
dns_init(ctx, skip_open) ?
|
||||
|
||||
* allow TCP queue?
|
||||
|
||||
* more accurate error reporting. Currently, udns always returns TEMPFAIL,
|
||||
but don't specify why it happened (ENOMEM, timeout, etc).
|
||||
|
||||
* check the error value returned by recvfrom() and
|
||||
sendto() and determine which errors to ignore.
|
||||
|
||||
* maybe merge dns_timeouts() and dns_ioevent(), to have
|
||||
only one entry point for everything? For traditional
|
||||
select-loop-based eventloop it may be easier, but for
|
||||
callback-driven event loops the two should be separate.
|
||||
Provide an option, or a single dns_events() entry point
|
||||
for select-loop approach, or just call dns_ioevent()
|
||||
from within dns_timeouts() (probably after renaming
|
||||
it to be dns_events()) ?
|
||||
|
||||
* implement /etc/hosts lookup too, ala [c-]ares??
|
||||
|
||||
* sortlist support?

.SH DESCRIPTION
|
||||
.B dnsget
|
||||
is a simple command-line to perform DNS lookups, similar to
|
||||
.BR host (1)
|
||||
and
|
||||
.BR dig (1).
|
||||
It is useable for both interactive/debugging scenarious and
|
||||
in scripts.
|
||||
The program is implemented using
|
||||
.BR udns (3)
|
||||
library.
|
||||
|
||||
.PP
|
||||
By default,
|
||||
.B dnsget
|
||||
produces a human-readable output, similar to
|
||||
.RS
|
||||
.nf
|
||||
alias.example.com. CNAME www.example.com.
|
||||
www.example.com. A 192.168.1.1
|
||||
www.example.com. MX 10 mx.example.com.
|
||||
.fi
|
||||
.RE
|
||||
which is just sufficient to see how a given name resolves.
|
||||
Output format is controllable with
|
||||
.B \-v
|
||||
and
|
||||
.B \-q
|
||||
options -- the former increases verbosity level up to printing
|
||||
the whole DNS contents of all packets sent and received, which
|
||||
is suitable for debugging DNS problems, while the latter reduces
|
||||
the level, making output more quiet, up to bare result with no
|
||||
error messages, which is good for scripts.
|
||||
|
||||
.SH OPTIONS
|
||||
|
||||
The following options are recognized by
|
||||
.BR dnsget :
|
||||
|
||||
.TP
|
||||
.B \-v
|
||||
produce more detailed output. More
|
||||
.BR \-v 's
|
||||
means more details will be produced. With single
|
||||
.BR \-v , dnsget
|
||||
will print contents of all received DNS packets (in a readable format),
|
||||
while with
|
||||
.BR \-vv ,
|
||||
it will output all outgoing DNS packets too.
|
||||
|
||||
.TP
|
||||
.B \-q
|
||||
the opposite for \fB\-v\fR -- produce less detailed output.
|
||||
With single
|
||||
.BR \-q , dnsget
|
||||
will only show (decoded) data from final DNS resource records (RR),
|
||||
while
|
||||
.B \-qq
|
||||
also suppresses error messages.
|
||||
|
||||
.TP
|
||||
\fB\-t \fItype\fR
|
||||
request record(s) of the given type \fItype\fR. By default,
|
||||
.B dnsget
|
||||
will ask for IPv4 address (A) record, or for PTR record if the
|
||||
argument in question is an IPv4 or IPv6 address. Recognized
|
||||
types include A, AAAA, MX, TXT, CNAME, PTR, NS, SOA, ANY and
|
||||
others.
|
||||
|
||||
.TP
|
||||
\fB\-c \fIclass\fR
|
||||
request DNS record(s) of the given class \fIclass\fR. By
|
||||
default
|
||||
.B dnsget
|
||||
uses IN class. Valid classes include IN, CH, HS, ANY.
|
||||
|
||||
.TP
|
||||
.B \-a
|
||||
(compatibility option). Equivalent to setting query type to
|
||||
.B ANY
|
||||
and increasing verbosity level
|
||||
.RB ( \-v ).
|
||||
|
||||
.TP
|
||||
.B \-C
|
||||
(planned)
|

|
||||
|
||||
.TP
|
||||
\fB\-o \fIopt\fR,\fIopt\fR,...
|
||||
(may be specified several times).
|
||||
Set resolver options (in a form \fIoption\fR:\fIvalue\fR) as if they
|
||||
were set in
|
||||
.RB $ RES_OPTIONS
|
||||
environment variable, or set query flags:
|
||||
.RS
|
||||
.TP
|
||||
\fBtimeout\fR:\fIsec\fR
|
||||
Set initial query timeout to \fIsec\fR.
|
||||
.TP
|
||||
\fBattempts\fR:\fInum\fR
|
||||
(re)try every query \fInum\fR times before failing.
|
||||
.TP
|
||||
\fBudpbuf\fR:\fIbytes\fR
|
||||
set DNS UDP buffer size to \fIbytes\fR bytes. Valid values
|
||||
are from 512 to 65535. If \fIbytes\fR is greather than 512,
|
||||
EDNS0 (RFC 2671) extensions will be used.
|
||||
.TP
|
||||
\fBport\fR:\fInum\fR
|
||||
Use given UDP port number \fInum\fR instead of the default port 53 (domain).
|
||||
.TP
|
||||
\fBaa\fR
|
||||
set AA (auth only) query bit.
|
||||
.TP
|
||||
\fBnord\fR
|
||||
do not set RD (recursion desired) query bit (set by default).
|
||||
.TP
|
||||
\fBdnssec\fR or \fBdo\fR
|
||||
set DNSSEC OK (DO) query flag (\fBdnsget\fR does not verify DNSSEC signatures,
|
||||
only displays them; this is set in EDNS RR).
|
||||
.TP
|
||||
\fBcd\fR
|
||||
set CD (checking disabled) query bit.
|
||||
.RE
|
||||
|
||||
.TP
|
||||
\fB\-n \fInameserver\fR
|
||||
Use the given nameserver(s) (may be specified more than once)
|
||||
instead of the default. Using this option has the same same effect as
|
||||
.RB $ NSCACHEIP
|
||||
or
|
||||
.RB $ NAMESERVERS
|
||||
environment variables, with the only difference that only IPv4 addresses
|
||||
are recognized for now, and it is possible to specify names (which will
|
||||
be resolved using default settings) instead of IP addresses.
|
||||
|
||||
.TP
|
||||
.B \-h
|
||||
print short help and exit.
|
||||
|
||||
.SH "RETURN VALUE"
|
||||
When all names where resovled successefully,
|
||||
.B dnsget
|
||||
exits with zero exit status. If at least one name was not found,
|
||||
.B dnsget
|
||||
will exit with return code 100. If some other error occured during
|
||||
name resolution, it will exit with code 99. In case of usage or
|
||||
initialization error,
|
||||
.B dnsget
|
||||
will return 1.

/* inet_XtoX.c
|

* Simple implementation of the following functions:
|
||||
* inet_ntop(), inet_ntoa(), inet_pton(), inet_aton().
|
||||
*
|
||||
* Differences from traditional implementaitons:
|
||||
* o modifies destination buffers even on error return.
|
||||
* o no fancy (hex, or 1.2) input support in inet_aton()
|
||||
* o inet_aton() does not accept junk after an IP address.
|
||||
* o inet_ntop(AF_INET) requires at least 16 bytes in dest,
|
||||
* and inet_ntop(AF_INET6) at least 40 bytes
|
||||
* (traditional inet_ntop() will try to fit anyway)
|
||||
*
|
||||
* Compile with -Dinet_XtoX_prefix=pfx_ to have pfx_*() instead of inet_*()
|
||||
* Compile with -Dinet_XtoX_no_ntop or -Dinet_XtoX_no_pton
|
||||
* to disable net2str or str2net conversions.
|
||||
*
|
||||
* #define inet_XtoX_prototypes and #include "this_file.c"
|
||||
* to get function prototypes only (but not for inet_ntoa()).
|
||||
* #define inet_XtoX_decl to be `static' for static visibility,
|
||||
* or use __declspec(dllexport) or somesuch...
|
||||
*
|
||||
* Compile with -DTEST to test against stock implementation.

|

|
||||
.SH DESCRIPTION
|
||||
.B rblcheck
|
||||
is a simple command-line to perform DNSBL (DNS-based blocklists) lookups.
|
||||
For every IP address (or a name, in which case it will be resolved to an
|
||||
address first), the utility verifies whenever it is listed in a (list of)
|
||||
DNS blocklists specified with
|
||||
.B \-s
|
||||
or
|
||||
.B \-S
|
||||
options, optionally obtains text assotiated with the listing (usually it
|
||||
is either some description about the reason of the listing or an URL
|
||||
referring to such a description), and displays results on standard output.
|
||||
.PP
|
||||
The program is implemented on top of
|
||||
.BR udns (3)
|
||||
library.
|
||||
|
||||
.SH OPTIONS
|
||||
|
||||
The following options are recognized by
|
||||
.BR rblcheck :
|
||||
|
||||
.TP
|
||||
.B \-s \fIzone\fR
|
||||
add the given \fIzone\fR DNSBL name to the list of active zones.
|
||||
.TP
|
||||
.B \-S \fIzone-file\fR
|
||||
add list of zones from the named \fIzone-file\fR to the list of
|
||||
active zones (the file specifies one zone as the first word on a
|
||||
line, empty lines and lines starting with `#' character are ignored).
|
||||
.TP
|
||||
.B \-c
|
||||
reset active zone list.
|
||||
.TP
|
||||
.B \-v
|
||||
be more verbose, produce more detailed output.
|
||||
.TP
|
||||
.B \-q
|
||||
the opposite for \fB\-v\fR -- produce less detailed output.
|
||||
.TP
|
||||
.B \-t
|
||||
obtain text for listed addresses.
|
||||
.TP
|
||||
.B \-n \fInsaddr\fR
|
||||
Use the given nameserver (given as IPv4 or IPv6 address) instead of the
|
||||
default. The same effect may be achieved by setting $NSCACHEIP environment
|
||||
variable.
|
||||
.TP
|
||||
.B \-m
|
||||
stop after first hit, ie after the first address which is found to be
|
||||
listed.
|
||||
|
||||
.TP
|
||||
.B \-h
|
||||
print short help and exit.
|
||||
|
||||
.PP
|
||||
If no
|
||||
.BR \-s ,
|
||||
.BR \-S
|
||||
and
|
||||
.B \-c
|
||||
options are given,
|
||||
.B rblcheck
|
||||
will try to obtain list of zones using $RBLCHECK_ZONES environment variable,
|
||||
or ~/.rblcheckrc, or /etc/rblckechrc files, in that order. If no zones are
|
||||
found, it will exit unsuccessefully.
|
||||
|
||||
.SH "RETURN VALUE"
|
||||
When no addresses given are listed and no errors occured,
|
||||
.B rblcheck
|
||||
exits with code 0. If at least one address is listed,
|
||||
.B rblcheck
|
||||
returns 100. In case of DNS errors,
|
||||
.B rblcheck
|
||||
returns 2.
|
||||
|
||||
.SH ENVIRONMENT
|
||||
|
||||
.TP
|
||||
.B $RBLCHECK_ZONES
|
||||
if no
|
||||
.BR \-s ,
|
||||
.B \-S
|
||||
or
|
||||
.B \-c
|
||||
option is given,
|
||||
.B rblcheck
|
||||
tries this variable to obtain list of DNSBL zones to check against.
|
||||
|
||||
.SH FILES
|
||||
|
||||
.TP
|
||||
$HOME/.rblcheckrc and /etc/rblcheckrc
|
||||
if no
|
||||
.BR \-s ,
|
||||
.B \-S
|
||||
or
|
||||
.B \-c
|
||||
option is given, and no $RBLCHECK_ZONES environment variable is set,
|
||||
.B rblcheck
|
||||
will try the two files (the first one that exists) to obtain list of
|
||||
DNSBL zones to check against.
|
||||
Each line specifies one zone (only first word in each line is used).
|
||||
Empty lines and lines starting with `#' character are ignored.
