GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
51 Franklin St, 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.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, 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 or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
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 give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
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 Program or any portion
|
||||
of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
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 Program, 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 Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) 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; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, 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 executable. However, as a
|
||||
special exception, the source code 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.
|
||||
|
||||
If distribution of executable or 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 counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program 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.
|
||||
|
||||
5. 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 Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program 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 to
|
||||
this License.
|
||||
|
||||
7. 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 Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program 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 Program.
|
||||
|
||||
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.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program 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.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the 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 Program
|
||||
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 Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, 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
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), 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 Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. 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 program's name and a brief idea of what it does.>
|
||||

||||

|
||||

|
||||
(at your option) any later version.
|
||||
|
||||
This program 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 General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) 19yy name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

ChangeLog for hostapd
|
||||
|
||||
2010-04-18 - v0.7.2
|
||||
* fix WPS internal Registrar use when an external Registrar is also
|
||||
active
|
||||
* bsd: Cleaned up driver wrapper and added various low-level
|
||||
configuration options
|
||||
* TNC: fixed issues with fragmentation
|
||||
* EAP-TNC: add Flags field into fragment acknowledgement (needed to
|
||||
interoperate with other implementations; may potentially breaks
|
||||
compatibility with older wpa_supplicant/hostapd versions)
|
||||
* cleaned up driver wrapper API for multi-BSS operations
|
||||
* nl80211: fix multi-BSS and VLAN operations
|
||||
* fix number of issues with IEEE 802.11r/FT; this version is not
|
||||
backwards compatible with old versions
|
||||
* add SA Query Request processing in AP mode (IEEE 802.11w)
|
||||
* fix IGTK PN in group rekeying (IEEE 802.11w)
|
||||
* fix WPS PBC session overlap detection to use correct attribute
|
||||
* hostapd_notif_Assoc() can now be called with all IEs to simplify
|
||||
driver wrappers
|
||||
* work around interoperability issue with some WPS External Registrar
|
||||
implementations
|
||||
* nl80211: fix WPS IE update
|
||||
* hostapd_cli: add support for action script operations (run a script
|
||||
on hostapd events)
|
||||
* fix DH padding with internal crypto code (mainly, for WPS)
|
||||
* fix WPS association with both WPS IE and WPA/RSN IE present with
|
||||
driver wrappers that use hostapd MLME (e.g., nl80211)
|
||||
|
||||
2010-01-16 - v0.7.1
|
||||
* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
|
||||
is not fully backwards compatible, so out-of-tree driver wrappers
|
||||
will need modifications
|
||||
* cleaned up various module interfaces
|
||||
* merge hostapd and wpa_supplicant developers' documentation into a
|
||||
single document
|
||||
* fixed HT Capabilities IE with nl80211 drivers
|
||||
* moved generic AP functionality code into src/ap
|
||||
* WPS: handle Selected Registrar as union of info from all Registrars
|
||||
* remove obsolte Prism54.org driver wrapper
|
||||
* added internal debugging mechanism with backtrace support and memory
|
||||
allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
|
||||
* EAP-FAST server: piggyback Phase 2 start with the end of Phase 1
|
||||
* WPS: add support for dynamically selecting whether to provision the
|
||||
PSK as an ASCII passphrase or PSK
|
||||
* added support for WDS (4-address frame) mode with per-station virtual
|
||||
interfaces (wds_sta=1 in config file; only supported with
|
||||
driver=nl80211 for now)
|
||||
* fixed WPS Probe Request processing to handle missing required
|
||||
attribute
|
||||
* fixed PKCS#12 use with OpenSSL 1.0.0
|
||||
* detect bridge interface automatically so that bridge parameter in
|
||||
hostapd.conf becomes optional (though, it may now be used to
|
||||
automatically add then WLAN interface into a bridge with
|
||||
driver=nl80211)
|
||||
|
||||
2009-11-21 - v0.7.0
|
||||
* increased hostapd_cli ping interval to 5 seconds and made this
|
||||
configurable with a new command line options (-G<seconds>)
|
||||
* driver_nl80211: use Linux socket filter to improve performance
|
||||
* added support for external Registrars with WPS (UPnP transport)
|
||||
* 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
|
||||
* driver_nl80211: fixed STA accounting data collection (TX/RX bytes
|
||||
reported correctly; TX/RX packets not yet available from kernel)
|
||||
* added support for WPS USBA out-of-band mechanism with USB Flash
|
||||
Drives (UFD) (CONFIG_WPS_UFD=y)
|
||||
* fixed EAPOL/EAP reauthentication when using an external RADIUS
|
||||
authentication server
|
||||
* fixed TNC with EAP-TTLS
|
||||
* fixed IEEE 802.11r key derivation function to match with the standard
|
||||
(note: this breaks interoperability with previous version) [Bug 303]
|
||||
* fixed SHA-256 based key derivation function to match with the
|
||||
standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
|
||||
(note: this breaks interoperability with previous version) [Bug 307]
|
||||
* added number of code size optimizations to remove unnecessary
|
||||
functionality from the program binary based on build configuration
|
||||
(part of this automatic; part configurable with CONFIG_NO_* build
|
||||
options)
|
||||
* use shared driver wrapper files with wpa_supplicant
|
||||
* driver_nl80211: multiple updates to provide support for new Linux
|
||||
nl80211/mac80211 functionality
|
||||
* updated management frame protection to use IEEE Std 802.11w-2009
|
||||
* fixed number of small WPS issues and added workarounds to
|
||||
interoperate with common deployed broken implementations
|
||||
* added some IEEE 802.11n co-existance rules to disable 40 MHz channels
|
||||
or modify primary/secondary channels if needed based on neighboring
|
||||
networks
|
||||
* added support for NFC out-of-band mechanism with WPS
|
||||
* added preliminary support for IEEE 802.11r RIC processing
|
||||
|
||||
2009-01-06 - v0.6.7
|
||||
* added support for Wi-Fi Protected Setup (WPS)
|
||||
(hostapd can now be configured to act as an integrated WPS Registrar
|
||||
and provision credentials for WPS Enrollees using PIN and PBC
|
||||
methods; external wireless Registrar can configure the AP, but
|
||||
external WLAN Manager Registrars are not supported); WPS support can
|
||||
be enabled by adding CONFIG_WPS=y into .config and setting the
|
||||
runtime configuration variables in hostapd.conf (see WPS section in
|
||||
the example configuration file); new hostapd_cli commands wps_pin and
|
||||
wps_pbc are used to configure WPS negotiation; see README-WPS for
|
||||
more details
|
||||
* added IEEE 802.11n HT capability configuration (ht_capab)
|
||||
* added support for generating Country IE based on nl80211 regulatory
|
||||
information (added if ieee80211d=1 in configuration)
|
||||
* fixed WEP authentication (both Open System and Shared Key) with
|
||||
mac80211
|
||||
* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
|
||||
* added support for using driver_test over UDP socket
|
||||
* changed EAP-GPSK to use the IANA assigned EAP method type 51
|
||||
* updated management frame protection to use IEEE 802.11w/D7.0
|
||||
* fixed retransmission of EAP requests if no response is received
|
||||
|
||||
2008-11-23 - v0.6.6
|
||||
* added a new configuration option, wpa_ptk_rekey, that can be used to
|
||||
enforce frequent PTK rekeying, e.g., to mitigate some attacks against
|
||||
TKIP deficiencies
|
||||
* updated OpenSSL code for EAP-FAST to use an updated version of the
|
||||
session ticket overriding API that was included into the upstream
|
||||
OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
|
||||
needed with that version anymore)
|
||||
* changed channel flags configuration to read the information from
|
||||
the driver (e.g., via driver_nl80211 when using mac80211) instead of
|
||||
using hostapd as the source of the regulatory information (i.e.,
|
||||
information from CRDA is now used with mac80211); this allows 5 GHz
|
||||
channels to be used with hostapd (if allowed in the current
|
||||
regulatory domain)
|
||||
* fixed EAP-TLS message processing for the last TLS message if it is
|
||||
large enough to require fragmentation (e.g., if a large Session
|
||||
Ticket data is included)
|
||||
* fixed listen interval configuration for nl80211 drivers
|
||||
|
||||
2008-11-01 - v0.6.5
|
||||
* added support for SHA-256 as X.509 certificate digest when using the
|
||||
internal X.509/TLSv1 implementation
|
||||
* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
|
||||
identity lengths)
|
||||
* fixed internal TLSv1 implementation for abbreviated handshake (used
|
||||
by EAP-FAST server)
|
||||
* added support for setting VLAN ID for STAs based on local MAC ACL
|
||||
(accept_mac_file) as an alternative for RADIUS server-based
|
||||
configuration
|
||||
* updated management frame protection to use IEEE 802.11w/D6.0
|
||||
(adds a new association ping to protect against unauthenticated
|
||||
authenticate or (re)associate request frames dropping association)
|
||||
* added support for using SHA256-based stronger key derivation for WPA2
|
||||
(IEEE 802.11w)
|
||||
* added new "driver wrapper" for RADIUS-only configuration
|
||||
(driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
|
||||
* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
|
||||
is enabled in configuration
|
||||
* changed EAP-FAST configuration to use separate fields for A-ID and
|
||||
A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
|
||||
16-octet len binary value for better interoperability with some peer
|
||||
implementations; eap_fast_a_id is now configured as a hex string
|
||||
* driver_nl80211: Updated to match the current Linux mac80211 AP mode
|
||||
configuration (wireless-testing.git and Linux kernel releases
|
||||
starting from 2.6.29)
|
||||
|
||||
2008-08-10 - v0.6.4
|
||||
* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
|
||||
Identity Request if identity is already known
|
||||
* added support for EAP Sequences in EAP-FAST Phase 2
|
||||
* added support for EAP-TNC (Trusted Network Connect)
|
||||
(this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
|
||||
changes needed to run two methods in sequence (IF-T) and the IF-IMV
|
||||
and IF-TNCCS interfaces from TNCS)
|
||||
* added support for optional cryptobinding with PEAPv0
|
||||
* added fragmentation support for EAP-TNC
|
||||
* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
|
||||
data
|
||||
* added support for opportunistic key caching (OKC)
|
||||
|
||||
2008-02-22 - v0.6.3
|
||||
* fixed Reassociation Response callback processing when using internal
|
||||
MLME (driver_{hostap,nl80211,test}.c)
|
||||
* updated FT support to use the latest draft, IEEE 802.11r/D9.0
|
||||
* copy optional Proxy-State attributes into RADIUS response when acting
|
||||
as a RADIUS authentication server
|
||||
* fixed EAPOL state machine to handle a case in which no response is
|
||||
received from the RADIUS authentication server; previous version
|
||||
could have triggered a crash in some cases after a timeout
|
||||
* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
|
||||
be used
|
||||
* added a workaround for EAP-SIM/AKA peers that include incorrect null
|
||||
termination in the username
|
||||
* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
|
||||
attribute in notification messages only when using fast
|
||||
reauthentication
|
||||
* fixed EAP-SIM Start response processing for fast reauthentication
|
||||
case
|
||||
* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
|
||||
phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
|
||||
|
||||
2008-01-01 - v0.6.2
|
||||
* fixed EAP-SIM and EAP-AKA message parser to validate attribute
|
||||
lengths properly to avoid potential crash caused by invalid messages
|
||||
* added data structure for storing allocated buffers (struct wpabuf);
|
||||
this does not affect hostapd usage, but many of the APIs changed
|
||||
and various interfaces (e.g., EAP) is not compatible with old
|
||||
versions
|
||||
* added support for protecting EAP-AKA/Identity messages with
|
||||
AT_CHECKCODE (optional feature in RFC 4187)
|
||||
* added support for protected result indication with AT_RESULT_IND for
|
||||
EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
|
||||
* added support for configuring EAP-TTLS phase 2 non-EAP methods in
|
||||
EAP server configuration; previously all four were enabled for every
|
||||
phase 2 user, now all four are disabled by default and need to be
|
||||
enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
|
||||
TTLS-MSCHAPV2
|
||||
* removed old debug printing mechanism and the related 'debug'
|
||||
parameter in the configuration file; debug verbosity is now set with
|
||||
-d (or -dd) command line arguments
|
||||
* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
|
||||
only shared key/password authentication is supported in this version
|
||||
|
||||
2007-11-24 - v0.6.1
|
||||
* added experimental, integrated TLSv1 server implementation with the
|
||||
needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
|
||||
setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
|
||||
.config); this can be useful, e.g., if the target system does not
|
||||
have a suitable TLS library and a minimal code size is required
|
||||
* added support for EAP-FAST server method to the integrated EAP
|
||||
server
|
||||
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
|
||||
draft (draft-ietf-emu-eap-gpsk-07.txt)
|
||||
* added a new configuration parameter, rsn_pairwise, to allow different
|
||||
pairwise cipher suites to be enabled for WPA and RSN/WPA2
|
||||
(note: if wpa_pairwise differs from rsn_pairwise, the driver will
|
||||
either need to support this or will have to use the WPA/RSN IEs from
|
||||
hostapd; currently, the included madwifi and bsd driver interfaces do
|
||||
not have support for this)
|
||||
* updated FT support to use the latest draft, IEEE 802.11r/D8.0
|
||||
|
||||
2007-05-28 - v0.6.0
|
||||
* added experimental IEEE 802.11r/D6.0 support
|
||||
* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
|
||||
* updated EAP-PSK to use the IANA-allocated EAP type 47
|
||||
* fixed EAP-PSK bit ordering of the Flags field
|
||||
* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
|
||||
by reading wpa_psk_file [Bug 181]
|
||||
* fixed EAP-TTLS AVP parser processing for too short AVP lengths
|
||||
* fixed IPv6 connection to RADIUS accounting server
|
||||
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
|
||||
draft (draft-ietf-emu-eap-gpsk-04.txt)
|
||||
* hlr_auc_gw: read GSM triplet file into memory and rotate through the
|
||||
entries instead of only using the same three triplets every time
|
||||
(this does not work properly with tests using multiple clients, but
|
||||
provides bit better triplet data for testing a single client; anyway,
|
||||
if a better quality triplets are needed, GSM-Milenage should be used
|
||||
instead of hardcoded triplet file)
|
||||
* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
|
||||
in Success Request [Bug 203]
|
||||
* added support for sending EAP-AKA Notifications in error cases
|
||||
* updated to use IEEE 802.11w/D2.0 for management frame protection
|
||||
(still experimental)
|
||||
* RADIUS server: added support for processing duplicate messages
|
||||
(retransmissions from RADIUS client) by replying with the previous
|
||||
reply
|
||||
|
||||
2006-11-24 - v0.5.6
|
||||
* added support for configuring and controlling multiple BSSes per
|
||||
radio interface (bss=<ifname> in hostapd.conf); this is only
|
||||
available with Devicescape and test driver interfaces
|
||||
* fixed PMKSA cache update in the end of successful RSN
|
||||
pre-authentication
|
||||
* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
|
||||
for each STA based on RADIUS Access-Accept attributes); this requires
|
||||
VLAN support from the kernel driver/802.11 stack and this is
|
||||
currently only available with Devicescape and test driver interfaces
|
||||
* driver_madwifi: fixed configuration of unencrypted modes (plaintext
|
||||
and IEEE 802.1X without WEP)
|
||||
* removed STAKey handshake since PeerKey handshake has replaced it in
|
||||
IEEE 802.11ma and there are no known deployments of STAKey
|
||||
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
|
||||
draft (draft-ietf-emu-eap-gpsk-01.txt)
|
||||
* added preliminary implementation of IEEE 802.11w/D1.0 (management
|
||||
frame protection)
|
||||
(Note: this requires driver support to work properly.)
|
||||
(Note2: IEEE 802.11w is an unapproved draft and subject to change.)
|
||||
* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
|
||||
* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
|
||||
parameters from a text file to make it possible to implement proper
|
||||
GSM/UMTS authentication server for multiple SIM/USIM cards using
|
||||
EAP-SIM/EAP-AKA
|
||||
* fixed session timeout processing with drivers that do not use
|
||||
ieee802_11.c (e.g., madwifi)
|
||||
|
||||
2006-08-27 - v0.5.5
|
||||
* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
|
||||
hostapd (e.g., to initialize wired network authentication based on an
|
||||
external signal)
|
||||
* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
|
||||
using WPA2 even if PMKSA caching is not used
|
||||
* added -P<pid file> argument for hostapd to write the current process
|
||||
id into a file
|
||||
* added support for RADIUS Authentication Server MIB (RFC 2619)
|
||||
|
||||
2006-06-20 - v0.5.4
|
||||
* fixed nt_password_hash build [Bug 144]
|
||||
* added PeerKey handshake implementation for IEEE 802.11e
|
||||
direct link setup (DLS) to replace STAKey handshake
|
||||
* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
|
||||
draft-clancy-emu-eap-shared-secret-00.txt)
|
||||
* fixed a segmentation fault when RSN pre-authentication was completed
|
||||
successfully [Bug 152]
|
||||
|
||||
2006-04-27 - v0.5.3
|
||||
* do not build nt_password_hash and hlr_auc_gw by default to avoid
|
||||
requiring a TLS library for a successful build; these programs can be
|
||||
build with 'make nt_password_hash' and 'make hlr_auc_gw'
|
||||
* added a new configuration option, eapol_version, that can be used to
|
||||
set EAPOL version to 1 (default is 2) to work around broken client
|
||||
implementations that drop EAPOL frames which use version number 2
|
||||
[Bug 89]
|
||||
* added support for EAP-SAKE (no EAP method number allocated yet, so
|
||||
this is using the same experimental type 255 as EAP-PSK)
|
||||
* fixed EAP-MSCHAPv2 message length validation
|
||||
|
||||
2006-03-19 - v0.5.2
|
||||
* fixed stdarg use in hostapd_logger(): if both stdout and syslog
|
||||
logging was enabled, hostapd could trigger a segmentation fault in
|
||||
vsyslog on some CPU -- C library combinations
|
||||
* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
|
||||
program to make it easier to use for implementing real SS7 gateway;
|
||||
eap_sim_db is not anymore used as a file name for GSM authentication
|
||||
triplets; instead, it is path to UNIX domain socket that will be used
|
||||
to communicate with the external gateway program (e.g., hlr_auc_gw)
|
||||
* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
|
||||
local information (GSM authentication triplets from a text file and
|
||||
hardcoded AKA authentication data); this can be used to test EAP-SIM
|
||||
and EAP-AKA
|
||||
* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
|
||||
to make it possible to test EAP-AKA with real USIM cards (this is
|
||||
disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
|
||||
to enable this)
|
||||
* driver_madwifi: added support for getting station RSN IE from
|
||||
madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
|
||||
broken with earlier change (r1357) in the driver
|
||||
* changed EAP method registration to use a dynamic list of methods
|
||||
instead of a static list generated at build time
|
||||
* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
|
||||
[Bug 125]
|
||||
* added ap_max_inactivity configuration parameter
|
||||
|
||||
2006-01-29 - v0.5.1
|
||||
* driver_test: added better support for multiple APs and STAs by using
|
||||
a directory with sockets that include MAC address for each device in
|
||||
the name (test_socket=DIR:/tmp/test)
|
||||
* added support for EAP expanded type (vendor specific EAP methods)
|
||||
|
||||
2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
|
||||
* added experimental STAKey handshake implementation for IEEE 802.11e
|
||||
direct link setup (DLS); note: this is disabled by default in both
|
||||
build and runtime configuration (can be enabled with CONFIG_STAKEY=y
|
||||
and stakey=1)
|
||||
* added support for EAP methods to use callbacks to external programs
|
||||
by buffering a pending request and processing it after the EAP method
|
||||
is ready to continue
|
||||
* improved EAP-SIM database interface to allow external request to GSM
|
||||
HLR/AuC without blocking hostapd process
|
||||
* added support for using EAP-SIM pseudonyms and fast re-authentication
|
||||
* added support for EAP-AKA in the integrated EAP authenticator
|
||||
* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
|
||||
user database to allow EAP-SIM/AKA selection without extra roundtrip
|
||||
for EAP-Nak negotiation
|
||||
* added support for storing EAP user password as NtPasswordHash instead
|
||||
of plaintext password when using MSCHAP or MSCHAPv2 for
|
||||
authentication (hash:<16-octet hex value>); added nt_password_hash
|
||||
tool for hashing password to generate NtPasswordHash
|
||||
|
||||
2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
|
||||
* driver_wired: fixed EAPOL sending to optionally use PAE group address
|
||||
as the destination instead of supplicant MAC address; this is
|
||||
disabled by default, but should be enabled with use_pae_group_addr=1
|
||||
in configuration file if the wired interface is used by only one
|
||||
device at the time (common switch configuration)
|
||||
* driver_madwifi: configure driver to use TKIP countermeasures in order
|
||||
to get correct behavior (IEEE 802.11 association failing; previously,
|
||||
association succeeded, but hostpad forced disassociation immediately)
|
||||
* driver_madwifi: added support for madwifi-ng
|
||||
|
||||
2005-10-27 - v0.4.6
|
||||
* added support for replacing user identity from EAP with RADIUS
|
||||
User-Name attribute from Access-Accept message, if that is included,
|
||||
for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
|
||||
tunneled identity into accounting messages when the RADIUS server
|
||||
does not support better way of doing this with Class attribute)
|
||||
* driver_madwifi: fixed EAPOL packet receive for configuration where
|
||||
ath# is part of a bridge interface
|
||||
* added a configuration file and log analyzer script for logwatch
|
||||
* fixed EAPOL state machine step function to process all state
|
||||
transitions before processing new events; this resolves a race
|
||||
condition in which EAPOL-Start message could trigger hostapd to send
|
||||
two EAP-Response/Identity frames to the authentication server
|
||||
|
||||
2005-09-25 - v0.4.5
|
||||
* added client CA list to the TLS certificate request in order to make
|
||||
it easier for the client to select which certificate to use
|
||||
* added experimental support for EAP-PSK
|
||||
* added support for WE-19 (hostap, madwifi)
|
||||
|
||||
2005-08-21 - v0.4.4
|
||||
* fixed build without CONFIG_RSN_PREAUTH
|
||||
* fixed FreeBSD build
|
||||
|
||||
2005-06-26 - v0.4.3
|
||||
* fixed PMKSA caching to copy User-Name and Class attributes so that
|
||||
RADIUS accounting gets correct information
|
||||
* start RADIUS accounting only after successful completion of WPA
|
||||
4-Way Handshake if WPA-PSK is used
|
||||
* fixed PMKSA caching for the case where STA (re)associates without
|
||||
first disassociating
|
||||
|
||||
2005-06-12 - v0.4.2
|
||||
* EAP-PAX is now registered as EAP type 46
|
||||
* fixed EAP-PAX MAC calculation
|
||||
* fixed EAP-PAX CK and ICK key derivation
|
||||
* renamed eap_authenticator configuration variable to eap_server to
|
||||
better match with RFC 3748 (EAP) terminology
|
||||
* driver_test: added support for testing hostapd with wpa_supplicant
|
||||
by using test driver interface without any kernel drivers or network
|
||||
cards
|
||||
|
||||
2005-05-22 - v0.4.1
|
||||
* fixed RADIUS server initialization when only auth or acct server
|
||||
is configured and the other one is left empty
|
||||
* driver_madwifi: added support for RADIUS accounting
|
||||
* driver_madwifi: added preliminary support for compiling against 'BSD'
|
||||
branch of madwifi CVS tree
|
||||
* driver_madwifi: fixed pairwise key removal to allow WPA reauth
|
||||
without disassociation
|
||||
* added support for reading additional certificates from PKCS#12 files
|
||||
and adding them to the certificate chain
|
||||
* fixed RADIUS Class attribute processing to only use Access-Accept
|
||||
packets to update Class; previously, other RADIUS authentication
|
||||
packets could have cleared Class attribute
|
||||
* added support for more than one Class attribute in RADIUS packets
|
||||
* added support for verifying certificate revocation list (CRL) when
|
||||
using integrated EAP authenticator for EAP-TLS; new hostapd.conf
|
||||
options 'check_crl'; CRL must be included in the ca_cert file for now
|
||||
|
||||
2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
|
||||
* added support for including network information into
|
||||
EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
|
||||
(e.g., to implement draft-adrange-eap-network-discovery-07.txt)
|
||||
* fixed a bug which caused some RSN pre-authentication cases to use
|
||||
freed memory and potentially crash hostapd
|
||||
* fixed private key loading for cases where passphrase is not set
|
||||
* added support for sending TLS alerts and aborting authentication
|
||||
when receiving a TLS alert
|
||||
* fixed WPA2 to add PMKSA cache entry when using integrated EAP
|
||||
authenticator
|
||||
* fixed PMKSA caching (EAP authentication was not skipped correctly
|
||||
with the new state machine changes from IEEE 802.1X draft)
|
||||
* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
|
||||
and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
|
||||
to be added to .config to include IPv6 support); for RADIUS server,
|
||||
radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
|
||||
in RADIUS clients file can then use IPv6 format
|
||||
* added experimental support for EAP-PAX
|
||||
* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
|
||||
the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
|
||||
|
||||
2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
|
||||
|
||||
2005-01-23 - v0.3.5
|
||||
* added support for configuring a forced PEAP version based on the
|
||||
Phase 1 identity
|
||||
* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
|
||||
to terminate authentication
|
||||
* fixed EAP identifier duplicate processing with the new IEEE 802.1X
|
||||
draft
|
||||
* clear accounting data in the driver when starting a new accounting
|
||||
session
|
||||
* driver_madwifi: filter wireless events based on ifindex to allow more
|
||||
than one network interface to be used
|
||||
* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
|
||||
setting if the packet does not pass MIC verification (e.g., due to
|
||||
incorrect PSK); previously, message 1/4 was not tried again if an
|
||||
invalid message 2/4 was received
|
||||
* fixed reconfiguration of RADIUS client retransmission timer when
|
||||
adding a new message to the pending list; previously, timer was not
|
||||
updated at this point and if there was a pending message with long
|
||||
time for the next retry, the new message needed to wait that long for
|
||||
its first retry, too
|
||||
|
||||
2005-01-09 - v0.3.4
|
||||
* added support for configuring multiple allowed EAP types for Phase 2
|
||||
authentication (EAP-PEAP, EAP-TTLS)
|
||||
* fixed EAPOL-Start processing to trigger WPA reauthentication
|
||||
(previously, only EAPOL authentication was done)
|
||||
|
||||
2005-01-02 - v0.3.3
|
||||
* added support for EAP-PEAP in the integrated EAP authenticator
|
||||
* added support for EAP-GTC in the integrated EAP authenticator
|
||||
* added support for configuring list of EAP methods for Phase 1 so that
|
||||
the integrated EAP authenticator can, e.g., use the wildcard entry
|
||||
for EAP-TLS and EAP-PEAP
|
||||
* added support for EAP-TTLS in the integrated EAP authenticator
|
||||
* added support for EAP-SIM in the integrated EAP authenticator
|
||||
* added support for using hostapd as a RADIUS authentication server
|
||||
with the integrated EAP authenticator taking care of EAP
|
||||
authentication (new hostapd.conf options: radius_server_clients and
|
||||
radius_server_auth_port); this is not included in default build; use
|
||||
CONFIG_RADIUS_SERVER=y in .config to include
|
||||
|
||||
2004-12-19 - v0.3.2
|
||||
* removed 'daemonize' configuration file option since it has not really
|
||||
been used at all for more than year
|
||||
* driver_madwifi: fixed group key setup and added get_ssid method
|
||||
* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
|
||||
|
||||
2004-12-12 - v0.3.1
|
||||
* added support for integrated EAP-TLS authentication (new hostapd.conf
|
||||
variables: ca_cert, server_cert, private_key, private_key_passwd);
|
||||
this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
|
||||
external RADIUS server
|
||||
* added support for reading PKCS#12 (PFX) files (as a replacement for
|
||||
PEM/DER) to get certificate and private key (CONFIG_PKCS12)
|
||||
|
||||
2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
|
||||
* added support for Acct-{Input,Output}-Gigawords
|
||||
* added support for Event-Timestamp (in RADIUS Accounting-Requests)
|
||||
* added support for RADIUS Authentication Client MIB (RFC2618)
|
||||
* added support for RADIUS Accounting Client MIB (RFC2620)
|
||||
* made EAP re-authentication period configurable (eap_reauth_period)
|
||||
* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
|
||||
* fixed EAPOL state machine to stop if STA is removed during
|
||||
eapol_sm_step(); this fixes at least one segfault triggering bug with
|
||||
IEEE 802.11i pre-authentication
|
||||
* added support for multiple WPA pre-shared keys (e.g., one for each
|
||||
client MAC address or keys shared by a group of clients);
|
||||
new hostapd.conf field wpa_psk_file for setting path to a text file
|
||||
containing PSKs, see hostapd.wpa_psk for an example
|
||||
* added support for multiple driver interfaces to allow hostapd to be
|
||||
used with other drivers
|
||||
* added wired authenticator driver interface (driver=wired in
|
||||
hostapd.conf, see wired.conf for example configuration)
|
||||
* added madwifi driver interface (driver=madwifi in hostapd.conf, see
|
||||
madwifi.conf for example configuration; Note: include files from
|
||||
madwifi project is needed for building and a configuration file,
|
||||
.config, needs to be created in hostapd directory with
|
||||
CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
|
||||
build)
|
||||
* fixed an alignment issue that could cause SHA-1 to fail on some
|
||||
platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
|
||||
align variables)
|
||||
* fixed RADIUS reconnection after an error in sending interim
|
||||
accounting packets
|
||||
* added hostapd control interface for external programs and an example
|
||||
CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
|
||||
* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
|
||||
'hostapd_cli sta <addr>')
|
||||
* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
|
||||
* added support for strict GTK rekeying (wpa_strict_rekey in
|
||||
hostapd.conf)
|
||||
* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
|
||||
(instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
|
||||
IEEE 802.11F-2003)
|
||||
* added Prism54 driver interface (driver=prism54 in hostapd.conf;
|
||||
note: .config needs to be created in hostapd directory with
|
||||
CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
|
||||
build)
|
||||
* dual-licensed hostapd (GPLv2 and BSD licenses)
|
||||
* fixed RADIUS accounting to generate a new session id for cases where
|
||||
a station reassociates without first being complete deauthenticated
|
||||
* fixed STA disassociation handler to mark next timeout state to
|
||||
deauthenticate the station, i.e., skip long wait for inactivity poll
|
||||
and extra disassociation, if the STA disassociates without
|
||||
deauthenticating
|
||||
* added integrated EAP authenticator that can be used instead of
|
||||
external RADIUS authentication server; currently, only EAP-MD5 is
|
||||
supported, so this cannot yet be used for key distribution; the EAP
|
||||
method interface is generic, though, so adding new EAP methods should
|
||||
be straightforward; new hostapd.conf variables: 'eap_authenticator'
|
||||
and 'eap_user_file'; this obsoletes "minimal authentication server"
|
||||
('minimal_eap' in hostapd.conf) which is now removed
|
||||
* added support for FreeBSD and driver interface for the BSD net80211
|
||||
layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
|
||||
.config); please note that some of the required kernel mods have not
|
||||
yet been committed
|
||||
|
||||
2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
|
||||
* fixed some accounting cases where Accounting-Start was sent when
|
||||
IEEE 802.1X port was being deauthorized
|
||||
|
||||
2004-06-20 - v0.2.3
|
||||
* modified RADIUS client to re-connect the socket in case of certain
|
||||
error codes that are generated when a network interface state is
|
||||
changes (e.g., when IP address changes or the interface is set UP)
|
||||
* fixed couple of cases where EAPOL state for a station was freed
|
||||
twice causing a segfault for hostapd
|
||||
* fixed couple of bugs in processing WPA deauthentication (freed data
|
||||
was used)
|
||||
|
||||
2004-05-31 - v0.2.2
|
||||
* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
|
||||
* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
|
||||
cases where STAs dropped multicast frames as replay attacks
|
||||
* added support for copying RADIUS Attribute 'Class' from
|
||||
authentication messages into accounting messages
|
||||
* send canned EAP failure if RADIUS server sends Access-Reject without
|
||||
EAP message (previously, Supplicant was not notified in this case)
|
||||
* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
|
||||
not start EAPOL state machines if the STA selected to use WPA-PSK)
|
||||
|
||||
2004-05-06 - v0.2.1
|
||||
* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
|
||||
- based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
|
||||
(i.e., IEEE 802.11i/D3.0)
|
||||
- supports WPA-only, RSN-only, and mixed WPA/RSN mode
|
||||
- both WPA-PSK and WPA-RADIUS/EAP are supported
|
||||
- PMKSA caching and pre-authentication
|
||||
- new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
|
||||
wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
|
||||
rsn_preauth, rsn_preauth_interfaces
|
||||
* fixed interim accounting to remove any pending accounting messages
|
||||
to the STA before sending a new one
|
||||
|
||||
2004-02-15 - v0.2.0
|
||||
* added support for Acct-Interim-Interval:
|
||||
- draft-ietf-radius-acct-interim-01.txt
|
||||
- use Acct-Interim-Interval attribute from Access-Accept if local
|
||||
'radius_acct_interim_interval' is not set
|
||||
- allow different update intervals for each STA
|
||||
* fixed event loop to call signal handlers only after returning from
|
||||
the real signal handler
|
||||
* reset sta->timeout_next after successful association to make sure
|
||||
that the previously registered inactivity timer will not remove the
|
||||
STA immediately (e.g., if STA deauthenticates and re-associates
|
||||
before the timer is triggered).
|
||||
* added new hostapd.conf variable, nas_identifier, that can be used to
|
||||
add an optional RADIUS Attribute, NAS-Identifier, into authentication
|
||||
and accounting messages
|
||||
* added support for Accounting-On and Accounting-Off messages
|
||||
* fixed accounting session handling to send Accounting-Start only once
|
||||
per session and not to send Accounting-Stop if the session was not
|
||||
initialized properly
|
||||
* fixed Accounting-Stop statistics in cases where the message was
|
||||
previously sent after the kernel entry for the STA (and/or IEEE
|
||||
802.1X data) was removed
|
||||
|
||||
|
||||
Note:
|
||||
|
||||
Older changes up to and including v0.1.0 are included in the ChangeLog
|
||||
of the Host AP driver.

Introduction
|
||||
============
|
||||
|
||||
Originally, hostapd was an optional user space component for Host AP
|
||||
driver. It adds more features to the basic IEEE 802.11 management
|
||||
included in the kernel driver: using external RADIUS authentication
|
||||
server for MAC address based access control, IEEE 802.1X Authenticator
|
||||
and dynamic WEP keying, RADIUS accounting, WPA/WPA2 (IEEE 802.11i/RSN)
|
||||
Authenticator and dynamic TKIP/CCMP keying.
|
||||
|
||||
The current version includes support for other drivers, an integrated
|
||||
EAP server (i.e., allow full authentication without requiring
|
||||
an external RADIUS authentication server), and RADIUS authentication
|
||||
server for EAP authentication.
|
||||
|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
Current hardware/software requirements:
|
||||
- drivers:
|
||||
Host AP driver for Prism2/2.5/3.
|
||||
(http://hostap.epitest.fi/)
|
||||
Please note that station firmware version needs to be 1.7.0 or newer
|
||||
to work in WPA mode.
|
||||
|
||||
madwifi driver for cards based on Atheros chip set (ar521x)
|
||||
(http://sourceforge.net/projects/madwifi/)
|
||||
Please note that you will need to add the correct path for
|
||||
madwifi driver root directory in .config (see defconfig file for
|
||||
an example: CFLAGS += -I<path>)
|
||||
|
||||
mac80211-based drivers that support AP mode (with driver=nl80211).
|
||||
This includes drivers for Atheros (ath9k) and Broadcom (b43)
|
||||
chipsets.
|
||||
|
||||
Any wired Ethernet driver for wired IEEE 802.1X authentication
|
||||
(experimental code)
|
||||
|
||||
FreeBSD -current (with some kernel mods that have not yet been
|
||||
committed when hostapd v0.3.0 was released)
|
||||
BSD net80211 layer (e.g., Atheros driver)
|
||||
|
||||
|
||||
Build configuration
|
||||
-------------------
|
||||
|
||||
In order to be able to build hostapd, you will need to create a build
|
||||
time configuration file, .config that selects which optional
|
||||
components are included. See defconfig file for example configuration
|
||||
and list of available options.
|
||||
|
||||
|
||||
|
||||
IEEE 802.1X
|
||||
===========
|
||||
|
||||
IEEE Std 802.1X-2001 is a standard for port-based network access
|
||||
control. In case of IEEE 802.11 networks, a "virtual port" is used
|
||||
between each associated station and the AP. IEEE 802.11 specifies
|
||||
minimal authentication mechanism for stations, whereas IEEE 802.1X
|
||||
introduces a extensible mechanism for authenticating and authorizing
|
||||
users.
|
||||
|
||||
IEEE 802.1X uses elements called Supplicant, Authenticator, Port
|
||||
Access Entity, and Authentication Server. Supplicant is a component in
|
||||
a station and it performs the authentication with the Authentication
|
||||
Server. An access point includes an Authenticator that relays the packets
|
||||
between a Supplicant and an Authentication Server. In addition, it has a
|
||||
Port Access Entity (PAE) with Authenticator functionality for
|
||||
controlling the virtual port authorization, i.e., whether to accept
|
||||
packets from or to the station.
|
||||
|
||||
IEEE 802.1X uses Extensible Authentication Protocol (EAP). The frames
|
||||
between a Supplicant and an Authenticator are sent using EAP over LAN
|
||||
(EAPOL) and the Authenticator relays these frames to the Authentication
|
||||
Server (and similarly, relays the messages from the Authentication
|
||||
Server to the Supplicant). The Authentication Server can be colocated with the
|
||||
Authenticator, in which case there is no need for additional protocol
|
||||
for EAP frame transmission. However, a more common configuration is to
|
||||
use an external Authentication Server and encapsulate EAP frame in the
|
||||
frames used by that server. RADIUS is suitable for this, but IEEE
|
||||
802.1X would also allow other mechanisms.
|
||||
|
||||
Host AP driver includes PAE functionality in the kernel driver. It
|
||||
is a relatively simple mechanism for denying normal frames going to
|
||||
or coming from an unauthorized port. PAE allows IEEE 802.1X related
|
||||
frames to be passed between the Supplicant and the Authenticator even
|
||||
on an unauthorized port.
|
||||
|
||||
User space daemon, hostapd, includes Authenticator functionality. It
|
||||
receives 802.1X (EAPOL) frames from the Supplicant using the wlan#ap
|
||||
device that is also used with IEEE 802.11 management frames. The
|
||||
frames to the Supplicant are sent using the same device.
|
||||
|
||||
The normal configuration of the Authenticator would use an external
|
||||
Authentication Server. hostapd supports RADIUS encapsulation of EAP
|
||||
packets, so the Authentication Server should be a RADIUS server, like
|
||||
FreeRADIUS (http://www.freeradius.org/). The Authenticator in hostapd
|
||||
relays the frames between the Supplicant and the Authentication
|
||||
Server. It also controls the PAE functionality in the kernel driver by
|
||||
controlling virtual port authorization, i.e., station-AP
|
||||
connection, based on the IEEE 802.1X state.
|
||||
|
||||
When a station would like to use the services of an access point, it
|
||||
will first perform IEEE 802.11 authentication. This is normally done
|
||||
with open systems authentication, so there is no security. After
|
||||
this, IEEE 802.11 association is performed. If IEEE 802.1X is
|
||||
configured to be used, the virtual port for the station is set in
|
||||
Unauthorized state and only IEEE 802.1X frames are accepted at this
|
||||
point. The Authenticator will then ask the Supplicant to authenticate
|
||||
with the Authentication Server. After this is completed successfully,
|
||||
the virtual port is set to Authorized state and frames from and to the
|
||||
station are accepted.
|
||||
|
||||
Host AP configuration for IEEE 802.1X
|
||||
-------------------------------------
|
||||
|
||||
The user space daemon has its own configuration file that can be used to
|
||||
define AP options. Distribution package contains an example
|
||||
configuration file (hostapd/hostapd.conf) that can be used as a basis
|
||||
for configuration. It includes examples of all supported configuration
|
||||
options and short description of each option. hostapd should be started
|
||||
with full path to the configuration file as the command line argument,
|
||||
e.g., './hostapd /etc/hostapd.conf'. If you have more that one wireless
|
||||
LAN card, you can use one hostapd process for multiple interfaces by
|
||||
giving a list of configuration files (one per interface) in the command
|
||||
line.
|
||||
|
||||
hostapd includes a minimal co-located IEEE 802.1X server which can be
|
||||
used to test IEEE 802.1X authentication. However, it should not be
|
||||
used in normal use since it does not provide any security. This can be
|
||||
configured by setting ieee8021x and minimal_eap options in the
|
||||
configuration file.
|
||||
|
||||
An external Authentication Server (RADIUS) is configured with
|
||||
auth_server_{addr,port,shared_secret} options. In addition,
|
||||
ieee8021x and own_ip_addr must be set for this mode. With such
|
||||
configuration, the co-located Authentication Server is not used and EAP
|
||||
frames will be relayed using EAPOL between the Supplicant and the
|
||||
Authenticator and RADIUS encapsulation between the Authenticator and
|
||||
the Authentication Server. Other than this, the functionality is similar
|
||||
to the case with the co-located Authentication Server.
|
||||
|
||||
Authentication Server and Supplicant
|
||||
------------------------------------
|
||||
|
||||
Any RADIUS server supporting EAP should be usable as an IEEE 802.1X
|
||||
Authentication Server with hostapd Authenticator. FreeRADIUS
|
||||
(http://www.freeradius.org/) has been successfully tested with hostapd
|
||||
Authenticator and both Xsupplicant (http://www.open1x.org) and Windows
|
||||
XP Supplicants. EAP/TLS was used with Xsupplicant and
|
||||
EAP/MD5-Challenge with Windows XP.
|
||||
|
||||
http://www.missl.cs.umd.edu/wireless/eaptls/ has useful information
|
||||
about using EAP/TLS with FreeRADIUS and Xsupplicant (just replace
|
||||
Cisco access point with Host AP driver, hostapd daemon, and a Prism2
|
||||
card ;-). http://www.freeradius.org/doc/EAP-MD5.html has information
|
||||
about using EAP/MD5 with FreeRADIUS, including instructions for WinXP
|
||||
configuration. http://www.denobula.com/EAPTLS.pdf has a HOWTO on
|
||||
EAP/TLS use with WinXP Supplicant.
|
||||
|
||||
Automatic WEP key configuration
|
||||
-------------------------------
|
||||
|
||||
EAP/TLS generates a session key that can be used to send WEP keys from
|
||||
an AP to authenticated stations. The Authenticator in hostapd can be
|
||||
configured to automatically select a random default/broadcast key
|
||||
(shared by all authenticated stations) with wep_key_len_broadcast
|
||||
option (5 for 40-bit WEP or 13 for 104-bit WEP). In addition,
|
||||
wep_key_len_unicast option can be used to configure individual unicast
|
||||
keys for stations. This requires support for individual keys in the
|
||||
station driver.
|
||||
|
||||
WEP keys can be automatically updated by configuring rekeying. This
|
||||
will improve security of the network since same WEP key will only be
|
||||
used for a limited period of time. wep_rekey_period option sets the
|
||||
interval for rekeying in seconds.
|
||||

||||

||||
WPA/WPA2
|
||||
========
|
||||
|
||||
Features
|
||||
--------
|
||||
|
||||
Supported WPA/IEEE 802.11i features:
|
||||
- WPA-PSK ("WPA-Personal")
|
||||
- WPA with EAP (e.g., with RADIUS authentication server) ("WPA-Enterprise")
|
||||
- key management for CCMP, TKIP, WEP104, WEP40
|
||||
- RSN/WPA2 (IEEE 802.11i), including PMKSA caching and pre-authentication
|
||||
|
||||
WPA
|
||||
---
|
||||
|
||||
The original security mechanism of IEEE 802.11 standard was not
|
||||
designed to be strong and has proved to be insufficient for most
|
||||
networks that require some kind of security. Task group I (Security)
|
||||
of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
|
||||
to address the flaws of the base standard and has in practice
|
||||
completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
|
||||
802.11 standard was approved in June 2004 and this amendment is likely
|
||||
to be published in July 2004.
|
||||
|
||||
Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
|
||||
IEEE 802.11i work (draft 3.0) to define a subset of the security
|
||||
enhancements that can be implemented with existing wlan hardware. This
|
||||
is called Wi-Fi Protected Access<TM> (WPA). This has now become a
|
||||
mandatory component of interoperability testing and certification done
|
||||
by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
|
||||
site (http://www.wi-fi.org/OpenSection/protected_access.asp).
|
||||
|
||||
IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
|
||||
for protecting wireless networks. WEP uses RC4 with 40-bit keys,
|
||||
24-bit initialization vector (IV), and CRC32 to protect against packet
|
||||
forgery. All these choices have proven to be insufficient: key space is
|
||||
too small against current attacks, RC4 key scheduling is insufficient
|
||||
(beginning of the pseudorandom stream should be skipped), IV space is
|
||||
too small and IV reuse makes attacks easier, there is no replay
|
||||
protection, and non-keyed authentication does not protect against bit
|
||||
flipping packet data.
|
||||
|
||||
WPA is an intermediate solution for the security issues. It uses
|
||||
Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
|
||||
compromise on strong security and possibility to use existing
|
||||
hardware. It still uses RC4 for the encryption like WEP, but with
|
||||
per-packet RC4 keys. In addition, it implements replay protection,
|
||||
keyed packet authentication mechanism (Michael MIC).
|
||||
|
||||
Keys can be managed using two different mechanisms. WPA can either use
|
||||
an external authentication server (e.g., RADIUS) and EAP just like
|
||||
IEEE 802.1X is using or pre-shared keys without need for additional
|
||||
servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
|
||||
respectively. Both mechanisms will generate a master session key for
|
||||
the Authenticator (AP) and Supplicant (client station).
|
||||
|
||||
WPA implements a new key handshake (4-Way Handshake and Group Key
|
||||
Handshake) for generating and exchanging data encryption keys between
|
||||
the Authenticator and Supplicant. This handshake is also used to
|
||||
verify that both Authenticator and Supplicant know the master session
|
||||
key. These handshakes are identical regardless of the selected key
|
||||
management mechanism (only the method for generating master session
|
||||
key changes).
|
||||
|
||||
|
||||
IEEE 802.11i / WPA2
|
||||
-------------------
|
||||
|
||||
The design for parts of IEEE 802.11i that were not included in WPA has
|
||||
finished (May 2004) and this amendment to IEEE 802.11 was approved in
|
||||
June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
|
||||
version of WPA called WPA2. This includes, e.g., support for more
|
||||
robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
|
||||
to replace TKIP and optimizations for handoff (reduced number of
|
||||
messages in initial key handshake, pre-authentication, and PMKSA caching).
|
||||
|
||||
Some wireless LAN vendors are already providing support for CCMP in
|
||||
their WPA products. There is no "official" interoperability
|
||||
certification for CCMP and/or mixed modes using both TKIP and CCMP, so
|
||||
some interoperability issues can be expected even though many
|
||||
combinations seem to be working with equipment from different vendors.
|
||||
Testing for WPA2 is likely to start during the second half of 2004.
|
||||

hostapd and Wi-Fi Protected Setup (WPS)
|
||||
=======================================
|
||||
|
||||
This document describes how the WPS implementation in hostapd can be
|
||||
configured and how an external component on an AP (e.g., web UI) is
|
||||
used to enable enrollment of client devices.
|
||||
|
||||
|
||||
Introduction to WPS
|
||||
-------------------
|
||||
|
||||
Wi-Fi Protected Setup (WPS) is a mechanism for easy configuration of a
|
||||
wireless network. It allows automated generation of random keys (WPA
|
||||
passphrase/PSK) and configuration of an access point and client
|
||||
devices. WPS includes number of methods for setting up connections
|
||||
with PIN method and push-button configuration (PBC) being the most
|
||||
commonly deployed options.
|
||||
|
||||
While WPS can enable more home networks to use encryption in the
|
||||
wireless network, it should be noted that the use of the PIN and
|
||||
especially PBC mechanisms for authenticating the initial key setup is
|
||||
not very secure. As such, use of WPS may not be suitable for
|
||||
environments that require secure network access without chance for
|
||||
allowing outsiders to gain access during the setup phase.
|
||||
|
||||
WPS uses following terms to describe the entities participating in the
|
||||
network setup:
|
||||
- access point: the WLAN access point
|
||||
- Registrar: a device that control a network and can authorize
|
||||
addition of new devices); this may be either in the AP ("internal
|
||||
Registrar") or in an external device, e.g., a laptop, ("external
|
||||
Registrar")
|
||||
- Enrollee: a device that is being authorized to use the network
|
||||
|
||||
It should also be noted that the AP and a client device may change
|
||||
roles (i.e., AP acts as an Enrollee and client device as a Registrar)
|
||||
when WPS is used to configure the access point.
|
||||
|
||||
|
||||
More information about WPS is available from Wi-Fi Alliance:

||||

|
||||
|
||||
|
||||
hostapd implementation
|
||||
----------------------
|
||||
|
||||
hostapd includes an optional WPS component that can be used as an
|
||||
internal WPS Registrar to manage addition of new WPS enabled clients
|
||||
to the network. In addition, WPS Enrollee functionality in hostapd can
|
||||
be used to allow external WPS Registrars to configure the access
|
||||
point, e.g., for initial network setup. In addition, hostapd can proxy a
|
||||
WPS registration between a wireless Enrollee and an external Registrar
|
||||
(e.g., Microsoft Vista or Atheros JumpStart) with UPnP.
|
||||
|
||||
|
||||
hostapd configuration
|
||||
---------------------
|
||||
|
||||
WPS is an optional component that needs to be enabled in hostapd build
|
||||
configuration (.config). Here is an example configuration that
|
||||
includes WPS support and uses madwifi driver interface:
|
||||
|
||||
CONFIG_DRIVER_MADWIFI=y
|
||||
CFLAGS += -I/usr/src/madwifi-0.9.3
|
||||
CONFIG_WPS=y
|
||||
CONFIG_WPS2=y
|
||||
CONFIG_WPS_UPNP=y
|
||||
|
||||
|
||||
Following section shows an example runtime configuration
|
||||
(hostapd.conf) that enables WPS:
|
||||
|
||||
# Configure the driver and network interface
|
||||
driver=madwifi
|
||||
interface=ath0
|
||||
|
||||
# WPA2-Personal configuration for the AP
|
||||
ssid=wps-test
|
||||
wpa=2
|
||||
wpa_key_mgmt=WPA-PSK
|
||||
wpa_pairwise=CCMP
|
||||
# Default WPA passphrase for legacy (non-WPS) clients
|
||||
wpa_passphrase=12345678
|
||||
# Enable random per-device PSK generation for WPS clients
|
||||
# Please note that the file has to exists for hostapd to start (i.e., create an
|
||||
# empty file as a starting point).
|
||||
wpa_psk_file=/etc/hostapd.psk
|
||||
|
||||
# Enable control interface for PBC/PIN entry
|
||||
ctrl_interface=/var/run/hostapd
|
||||
|
||||
# Enable internal EAP server for EAP-WSC (part of Wi-Fi Protected Setup)
|
||||
eap_server=1
|
||||
|
||||
# WPS configuration (AP configured, do not allow external WPS Registrars)
|
||||
wps_state=2
|
||||
ap_setup_locked=1
|
||||
# If UUID is not configured, it will be generated based on local MAC address.
|
||||
uuid=87654321-9abc-def0-1234-56789abc0000
|
||||
wps_pin_requests=/var/run/hostapd.pin-req
|
||||
device_name=Wireless AP
|
||||
manufacturer=Company
|
||||
model_name=WAP
|
||||
model_number=123
|
||||
serial_number=12345
|
||||
device_type=6-0050F204-1
|
||||
os_version=01020300
|
||||
config_methods=label display push_button keypad
|
||||
|
||||
# if external Registrars are allowed, UPnP support could be added:
|
||||
#upnp_iface=br0
|
||||
#friendly_name=WPS Access Point
|
||||
|
||||
|
||||
External operations
|
||||
-------------------
|
||||
|
||||
WPS requires either a device PIN code (usually, 8-digit number) or a
|
||||
pushbutton event (for PBC) to allow a new WPS Enrollee to join the
|
||||
network. hostapd uses the control interface as an input channel for
|
||||
these events.
|
||||
|
||||
The PIN value used in the commands must be processed by an UI to
|
||||
remove non-digit characters and potentially, to verify the checksum
|
||||
digit. "hostapd_cli wps_check_pin <PIN>" can be used to do such
|
||||
processing. It returns FAIL if the PIN is invalid, or FAIL-CHECKSUM if
|
||||
the checksum digit is incorrect, or the processed PIN (non-digit
|
||||
characters removed) if the PIN is valid.
|
||||
|
||||
When a client device (WPS Enrollee) connects to hostapd (WPS
|
||||
Registrar) in order to start PIN mode negotiation for WPS, an
|
||||
identifier (Enrollee UUID) is sent. hostapd will need to be configured
|
||||
with a device password (PIN) for this Enrollee. This is an operation
|
||||
that requires user interaction (assuming there are no pre-configured
|
||||
PINs on the AP for a set of Enrollee).
|
||||
|
||||
The PIN request with information about the device is appended to the
|
||||
wps_pin_requests file (/var/run/hostapd.pin-req in this example). In
|
||||
addition, hostapd control interface event is sent as a notification of
|
||||
a new device. The AP could use, e.g., a web UI for showing active
|
||||
Enrollees to the user and request a PIN for an Enrollee.
|
||||
|
||||
The PIN request file has one line for every Enrollee that connected to
|
||||
the AP, but for which there was no PIN. Following information is
|
||||
provided for each Enrollee (separated with tabulators):
|
||||
- timestamp (seconds from 1970-01-01)
|
||||
- Enrollee UUID
|
||||
- MAC address
|
||||
- Device name
|
||||
- Manufacturer
|
||||
- Model Name
|
||||
- Model Number
|
||||
- Serial Number
|
||||
- Device category
|
||||
|
||||
Example line in the /var/run/hostapd.pin-req file:
|
||||
1200188391 53b63a98-d29e-4457-a2ed-094d7e6a669c Intel(R) Centrino(R) Intel Corporation Intel(R) Centrino(R) - - 1-0050F204-1
|
||||
|
||||
Control interface data:
|
||||
WPS-PIN-NEEDED [UUID-E|MAC Address|Device Name|Manufacturer|Model Name|Model Number|Serial Number|Device Category]
|
||||
For example:
|
||||
<2>WPS-PIN-NEEDED [53b63a98-d29e-4457-a2ed-094d7e6a669c|02:12:34:56:78:9a|Device|Manuf|Model|Model Number|Serial Number|1-0050F204-1]
|
||||
|
||||
When the user enters a PIN for a pending Enrollee, e.g., on the web
|
||||
UI), hostapd needs to be notified of the new PIN over the control
|
||||
interface. This can be done either by using the UNIX domain socket
|
||||
-based control interface directly (src/common/wpa_ctrl.c provides
|
||||
helper functions for using the interface) or by calling hostapd_cli.
|
||||
|
||||
Example command to add a PIN (12345670) for an Enrollee:
|
||||
|
||||
hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c 12345670
|
||||
|
||||
If the UUID-E is not available (e.g., Enrollee waits for the Registrar
|
||||
to be selected before connecting), wildcard UUID may be used to allow
|
||||
the PIN to be used once with any UUID:
|
||||
|
||||
hostapd_cli wps_pin any 12345670
|
||||
|
||||
To reduce likelihood of PIN being used with other devices or of
|
||||
forgetting an active PIN available for potential attackers, expiration
|
||||
time in seconds can be set for the new PIN (value 0 indicates no
|
||||
expiration):
|
||||
|
||||
hostapd_cli wps_pin any 12345670 300
|
||||
|
||||
If the MAC address of the enrollee is known, it should be configured
|
||||
to allow the AP to advertise list of authorized enrollees:
|
||||
|
||||
hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c \
|
||||
12345670 300 00:11:22:33:44:55
|
||||
|
||||
|
||||
After this, the Enrollee can connect to the AP again and complete WPS
|
||||
negotiation. At that point, a new, random WPA PSK is generated for the
|
||||
client device and the client can then use that key to connect to the
|
||||
AP to access the network.
|
||||
|
||||
|
||||
If the AP includes a pushbutton, WPS PBC mode can be used. It is
|
||||
enabled by pushing a button on both the AP and the client at about the
|
||||
same time (2 minute window). hostapd needs to be notified about the AP
|
||||
button pushed event over the control interface, e.g., by calling
|
||||
hostapd_cli:
|
||||
|
||||
hostapd_cli wps_pbc
|
||||
|
||||
At this point, the client has two minutes to complete WPS negotiation
|
||||
which will generate a new WPA PSK in the same way as the PIN method
|
||||
described above.
|
||||
|
||||
|
||||
When an external Registrar is used, the AP can act as an Enrollee and
|
||||
use its AP PIN. A static AP PIN (e.g., one one a label in the AP
|
||||
device) can be configured in hostapd.conf (ap_pin parameter). A more
|
||||
secure option is to use hostapd_cli wps_ap_pin command to enable the
|
||||
AP PIN only based on user action (and even better security by using a
|
||||
random AP PIN for each session, i.e., by using "wps_ap_pin random"
|
||||
command with a timeout value). Following commands are available for
|
||||
managing the dynamic AP PIN operations:
|
||||
|
||||
hostapd_cli wps_ap_pin disable
|
||||
- disable AP PIN (i.e., do not allow external Registrars to use it to
|
||||
learn the current AP settings or to reconfigure the AP)
|
||||
|
||||
hostapd_cli wps_ap_pin random [timeout]
|
||||
- generate a random AP PIN and enable it
|
||||
- if the optional timeout parameter is given, the AP PIN will be enabled
|
||||
for the specified number of seconds
|
||||
|
||||
hostapd_cli wps_ap_pin get
|
||||
- fetch the current AP PIN
|
||||
|
||||
hostapd_cli wps_ap_pin set <PIN> [timeout]
|
||||
- set the AP PIN and enable it
|
||||
- if the optional timeout parameter is given, the AP PIN will be enabled
|
||||
for the specified number of seconds
|
||||
|
||||
hostapd_cli get_config
|
||||
- display the current configuration
|
||||
|
||||
hostapd_cli wps_config <new SSID> <auth> <encr> <new key>
|
||||
examples:
|
||||
hostapd_cli wps_config testing WPA2PSK CCMP 12345678
|
||||
hostapd_cli wps_config "no security" OPEN NONE ""
|
||||
|
||||
<auth> must be one of the following: OPEN WPAPSK WPA2PSK
|
||||
<encr> must be one of the following: NONE WEP TKIP CCMP
|
||||
|
||||
|
||||
Credential generation and configuration changes
|
||||
-----------------------------------------------
|
||||
|
||||
By default, hostapd generates credentials for Enrollees and processing
|
||||
AP configuration updates internally. However, it is possible to
|
||||
control these operations from external programs, if desired.
|
||||
|
||||
The internal credential generation can be disabled with
|
||||
skip_cred_build=1 option in the configuration. extra_cred option will
|
||||
then need to be used to provide pre-configured Credential attribute(s)
|
||||
for hostapd to use. The exact data from this binary file will be sent,
|
||||
i.e., it will have to include valid WPS attributes. extra_cred can
|
||||
also be used to add additional networks if the Registrar is used to
|
||||
configure credentials for multiple networks.
|
||||
|
||||
Processing of received configuration updates can be disabled with
|
||||
wps_cred_processing=1 option. When this is used, an external program
|
||||
is responsible for creating hostapd configuration files and processing
|
||||
configuration updates based on messages received from hostapd over
|
||||
control interface. This will also include the initial configuration on
|
||||
first successful registration if the AP is initially set in
|
||||
unconfigured state.
|
||||
|
||||
Following control interface messages are sent out for external programs:
|
||||
|
||||
WPS-REG-SUCCESS <Enrollee MAC address <UUID-E>
|
||||
For example:
|
||||
<2>WPS-REG-SUCCESS 02:66:a0:ee:17:27 2b7093f1-d6fb-5108-adbb-bea66bb87333
|
||||
|
||||
This can be used to trigger change from unconfigured to configured
|
||||
state (random configuration based on the first successful WPS
|
||||
registration). In addition, this can be used to update AP UI about the
|
||||
status of WPS registration progress.
|
||||
|
||||
|
||||
WPS-NEW-AP-SETTINGS <hexdump of AP Setup attributes>
|
||||
For example:
|
||||
<2>WPS-NEW-AP-SETTINGS 10260001011045000c6a6b6d2d7770732d74657374100300020020100f00020008102700403065346230343536633236366665306433396164313535346131663462663731323433376163666462376633393965353466316631623032306164343438623510200006024231cede15101e000844
|
||||
|
||||
This can be used to update the externally stored AP configuration and
|
||||
then update hostapd configuration (followed by restarting of hostapd).

# hostapd depends on strong random number generation being available from the
|
||||
# operating system. os_get_random() function is used to fetch random data when
|
||||
# needed, e.g., for key generation. On Linux and BSD systems, this works by
|
||||
# reading /dev/urandom. It should be noted that the OS entropy pool needs to be
|
||||
# properly initialized before hostapd is started. This is important especially
|
||||
# on embedded devices that do not have a hardware random number generator and
|
||||
# may by default start up with minimal entropy available for random number
|
||||
# generation.
|
||||
#
|
||||
# As a safety net, hostapd is by default trying to internally collect
|
||||
# additional entropy for generating random data to mix in with the data
|
||||
# fetched from the OS. This by itself is not considered to be very strong, but
|
||||
# it may help in cases where the system pool is not initialized properly.
|
||||
# However, it is very strongly recommended that the system pool is initialized
|
||||
# with enough entropy either by using hardware assisted random number
|
||||
# generatior or by storing state over device reboots.
|
||||
#
|
||||
# If the os_get_random() is known to provide strong ramdom data (e.g., on
|
||||
# Linux/BSD, the board in question is known to have reliable source of random
|
||||
# data from /dev/urandom), the internal hostapd random pool can be disabled.
|
||||
# This will save some in binary size and CPU use. However, this should only be
|
||||
# considered for builds that are known to be used on devices that meet the
|
||||
# requirements described above.

|
||||
*
|
||||
* This is an example implementation of the EAP-SIM/AKA database/authentication
|
||||
* gateway interface to HLR/AuC. It is expected to be replaced with an
|
||||
* implementation of SS7 gateway to GSM/UMTS authentication center (HLR/AuC) or
|
||||
* a local implementation of SIM triplet and AKA authentication data generator.
|
||||
*
|
||||
* hostapd will send SIM/AKA authentication queries over a UNIX domain socket
|
||||
* to and external program, e.g., this hlr_auc_gw. This interface uses simple
|
||||
* text-based format:
|
||||
*
|
||||
* EAP-SIM / GSM triplet query/response:
|
||||
* SIM-REQ-AUTH <IMSI> <max_chal>
|
||||
* SIM-RESP-AUTH <IMSI> Kc1:SRES1:RAND1 Kc2:SRES2:RAND2 [Kc3:SRES3:RAND3]
|
||||
* SIM-RESP-AUTH <IMSI> FAILURE
|
||||
*
|
||||
* EAP-AKA / UMTS query/response:
|
||||
* AKA-REQ-AUTH <IMSI>
|
||||
* AKA-RESP-AUTH <IMSI> <RAND> <AUTN> <IK> <CK> <RES>
|
||||
* AKA-RESP-AUTH <IMSI> FAILURE
|
||||
*
|
||||
* EAP-AKA / UMTS AUTS (re-synchronization):
|
||||
* AKA-AUTS <IMSI> <AUTS> <RAND>
|
||||
*
|
||||
* IMSI and max_chal are sent as an ASCII string,
|
||||
* Kc/SRES/RAND/AUTN/IK/CK/RES/AUTS as hex strings.
|
||||
*
|
||||
* The example implementation here reads GSM authentication triplets from a
|
||||
* text file in IMSI:Kc:SRES:RAND format, IMSI in ASCII, other fields as hex
|
||||
* strings. This is used to simulate an HLR/AuC. As such, it is not very useful
|
||||
* for real life authentication, but it is useful both as an example
|
||||
* implementation and for EAP-SIM testing.

.PP
|
||||
.B hostapd
|
||||
is a user space daemon for access point and authentication servers.
|
||||
It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators and RADIUS authentication server.
|
||||
The current version supports Linux (Host AP, madwifi, mac80211-based drivers) and FreeBSD (net80211).
|

# identity can be used in the unencrypted phase 1 and the real user identity
|
||||
# is transmitted only within the encrypted tunnel in phase 2. If non-anonymous
|
||||
# access is needed, two user entries is needed, one for phase 1 and another
|
||||
# with the same username for phase 2.
|
||||
#
|
||||
# EAP-TLS, EAP-PEAP, EAP-TTLS, EAP-FAST, EAP-SIM, and EAP-AKA do not use
|
||||
# password option.
|
||||
# EAP-MD5, EAP-MSCHAPV2, EAP-GTC, EAP-PAX, EAP-PSK, and EAP-SAKE require a
|
||||
# password.
|

# EAP-PEAP, EAP-TTLS, and EAP-FAST require Phase 2 configuration.
|
||||
#
|
||||
# * can be used as a wildcard to match any user identity. The main purposes for
|
||||
# this are to set anonymous phase 1 identity for EAP-PEAP and EAP-TTLS and to
|
||||
# avoid having to configure every certificate for EAP-TLS authentication. The
|
||||
# first matching entry is selected, so * should be used as the last phase 1
|
||||
# user entry.
|
||||
#
|
||||
# "prefix"* can be used to match the given prefix and anything after this. The
|
||||
# main purpose for this is to be able to avoid EAP method negotiation when the
|
||||
# method is using known prefix in identities (e.g., EAP-SIM and EAP-AKA). This
|
||||
# is only allowed for phase 1 identities.
|
||||
#
|
||||
# Multiple methods can be configured to make the authenticator try them one by
|
||||
# one until the peer accepts one. The method names are separated with a
|
||||
# comma (,).
|
||||
#
|
||||
# [ver=0] and [ver=1] flags after EAP type PEAP can be used to force PEAP
|
||||
# version based on the Phase 1 identity. Without this flag, the EAP
|
||||
# authenticator advertises the highest supported version and select the version
|
||||
# based on the first PEAP packet from the supplicant.
|
||||
#
|
||||
# EAP-TTLS supports both EAP and non-EAP authentication inside the tunnel.
|
||||
# Tunneled EAP methods are configured with standard EAP method name and [2]
|
||||
# flag. Non-EAP methods can be enabled by following method names: TTLS-PAP,
|
||||
# TTLS-CHAP, TTLS-MSCHAP, TTLS-MSCHAPV2. TTLS-PAP and TTLS-CHAP require a
|
||||

Logwatch is a utility for analyzing system logs and provide a human
|
||||
readable summary. This directory has a configuration file and a log
|
||||
analyzer script for parsing hostapd system log entries for logwatch.
|
||||
These files can be installed by copying them to following locations:
|
||||
|
||||
/etc/log.d/conf/services/hostapd.conf
|
