hostapd won't work with the prism54 driver

[gsurbey]

I'm trying to get my prism54 card to work as a WPA enabled Access Point. I know that on the prism54 site it states that there is no wireless client wpa support however on the hostapd site it states that it will run with the Prism54 driver to create a WPA Access Point. So I downloaded the prism54-svn=20050501 snapshot and followed these instructions in order to be sure I have the latest driver. I also placed "=net-wireless/hostapd-0.4.1 ~x86" in my /etc/portage/package.keywords file so I emerged the latest version of that.

Still, I get the following error:

Code: Select all

testbox ~ # /usr/sbin/hostapd -d /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
Opening raw packet socket for ifindex 6
ioctl(SIOCGIFINDEX): No such device
prism54 driver initialization failed.
rmdir[ctrl_interface]: No such file or directory

This error has been reported elsewhere. Anyone have ideas?

My /etc/conf.d/hostapd file:

Code: Select all

INTERFACES="eth1"
CONFIGS="/etc/hostapd/hostapd.conf"
OPTIONS="-B"

My /etc/hostapd/hostapd.conf file:

Code: Select all

Hi.
many peoples had this problem and no one got an answer.

If you are still interested, I solved this problem this way:
Download the source code from http://hostap.epitest.fi/releases/hostapd-0.4.8.tar.gz
Modify the driver_prism54.c and remove in line 976 (snprintf(ifr.ifr_name, sizeof(ifr.ifr_name), "%sap", drv->iface)) the *ap* from "%sap".

This is because if you set the interface to "eth1" hostapd tries to open "eth1ap" which doesn't exist.
I don't know why "ethXap" is used instead of "ethX", but it works for me.

Thank you for your very informative reply ziererk. It worked!
This is how I modified my install:

Code: Select all

ACCEPT_KEYWORDS="~x86" emerge -f hostapd
mv /usr/portage/distfiles/hostapd-0.5.7.tar.gz .
tar -xvf hostapd-0.5.7.tar.gz
cd hostapd-0.5.7
vi driver_prism54.c
Line 1006
cd ..
tar -czv hostapd-0.5.7 -f hostapd-0.5.7.tar.gz
rm -R hostapd-0.5.7/
mv hostapd-0.5.7.tar.gz /usr/portage/distfiles/
ebuild /usr/portage/net-wireless/hostapd/hostapd-0.5.7.ebuild digest
ACCEPT_KEYWORDS="~x86" emerge hostapd

However I still can't get hostapd to work correctly. No matter how I do the settings WEP or WAP my wireless access point always shows up as open and unsecured.
