<h2>Host AP driver for Intersil Prism2/2.5/3, hostapd, and WPA Supplicant</h2>
|
|
|
|
<h3><a name="intro">Introduction</a></h3>
|
|
|
|
<p>This project includes three main components:</p>
|
|
<ul>
|
|
<li>Host AP - Linux driver for Prism2/2.5/3</li>
|
|
<li><a href="hostapd/">hostapd</a> - user space daemon for access points,
|
|
including, e.g., IEEE 802.1X/WPA/EAP Authenticator for number of Linux and
|
|
BSD drivers, RADIUS client, integrated EAP server, and RADIUS
|
|
authentication server</li>
|
|
<li><a href="wpa_supplicant/">wpa_supplicant</a> user space IEEE 802.1X/WPA
|
|
supplicant (wireless client) for number of Linux, BSD, and Windows
|
|
drivers</li>
|
|
</ul>
|
|
|
|
<p>
|
|
Host AP is a Linux driver for wireless LAN cards based on Intersil's
|
|
Prism2/2.5/3 chipset. The driver supports a so called Host AP mode, i.e., it
|
|
takes care of IEEE 802.11 management functions in the host computer
|
|
and acts as an access point. This does not require any special
|
|
firmware for the wireless LAN card. In addition to this, it has
|
|
support for normal station operations in BSS and possible also in
|
|
IBSS. WPA and RSN (WPA2) is supported when used with accompanied tools,
|
|
wpa_supplicant (WPA/RSN Supplicant) and hostapd (WPA/RSN Authenticator). All
|
|
these programs have been designed for both desktop/laptop computers and
|
|
embedded systems.
|
|
</p>
|
|
|
|
<p>
|
|
Intersil's station firmware for Prism2 chipset supports a so called
|
|
Host AP mode in which the firmware takes care of time critical tasks
|
|
like beacon sending and frame acknowledging, but leaves other
|
|
management tasks to host computer driver. This driver implements basic
|
|
functionality needed to initialize and configure Prism2-based cards,
|
|
to send and receive frames, and to gather statistics. In addition, it
|
|
includes an implementation of following IEEE 802.11 functions:
|
|
authentication (and deauthentication), association (reassociation, and
|
|
disassociation), data transmission between two wireless stations,
|
|
power saving (PS) mode signaling and frame buffering for PS
|
|
stations. The driver has also various features for development
|
|
debugging and for researching IEEE 802.11 environments like access to
|
|
hardware configuration records, I/O registers, and frames with 802.11
|
|
headers.
|
|
</p>
|
|
|
|
<p>
|
|
When used with a user space daemon, the combination of the Host AP
|
|
driver and hostapd daemon includes additional features. These include
|
|
support for IEEE 802.1X and dynamic WEP rekeying, RADIUS Accounting,
|
|
RADIUS-based ACL for IEEE 802.11 authentication, minimal IAPP (IEEE
|
|
802.11f), WPA, IEEE 802.11i/RSN/WPA2.

<a href="http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wireless.html">Linux

|
Wireless LAN Howto</a> has some useful information about wireless LAN support
|
|
in Linux. In addition, it includes information about which cards are
|
|
Prism2-based (and can thus be used in Host AP mode).

Host AP driver was added into the main kernel tree in Linux

v2.6.14. The version in the kernel tree should be used instead of this

|
external hostap-driver package. The external releases are only for
|
|
older kernel versions and all the future development will be in the
|
|
main kernel tree.

<h3>Wireless Tools for Linux</h3>
|
|
|
|
<p>
|
|
Please, note that you will need quite recent version of Wireless Tools
|
|
to use some features of the Host AP driver. Using the
|
|
<a href="http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html#latest">latest</a>
|
|
version of the tools is recommended. Some features might also require latest beta version.
|
|
</p>
|
|
|
|
<h3>Feedback, comments, mailing list</h3>
|
|
|
|
<p>
|
|
Any comments, reports on success/failure, ideas for further
|
|
improvement, feature requests, etc. are welcome at j@w1.fi.
|
|
Please note, that I often receive more email than I have time to answer.
|
|
Unfortunately, some messages may not get a reply, but I'll try to go
|
|
through my mail whenever time permits.
|
|
</p>
|
|
|
|
<p>
|
|
There is also a mailing list for Host AP related messages.
|
|
Since this list has a broader audience, your likelyhood of getting
|
|
responses is higher. This list is recommended for general questions
|
|
about Host AP driver and its development. In addition, I will send
|
|
release notes to it whenever a new version is available.
|
|
</p>
|
|
|
|
<p>
|
|
The mailing list information and web archive is at <a
|
|
href="http://lists.shmoo.com/mailman/listinfo/hostap">http://lists.shmoo.com/mailman/listinfo/hostap</a>.
|
|
Messages to hostap@shmoo.com will be delivered to the
|
|
subscribers. Please note, that due to large number of spam and virus
|
|
messages sent to the list address, the list is configured to accept
|
|
messages only from subscribed addresses. Messages from unsubscribed addresses
|
|
may be accepted manually, but their delivery will be delayed.
|
|

|
If you want to make sure your bug report of feature request does not
|
|
get lost, please report it through the bug tracking system as
