Description Fabrice Bellet 2008-08-18 14:13:48 UTC

The bug occurs with kernel-2.6.25.11-97.fc9.i686, using driver iwl3945. When setting adhoc-mode, the patch wpa_supplicant-0.6.3-wext-handle-mac80211-mode-switches.patch brings the interface down before setting the mode, and up just after. The problem is that this patch causes the wep keys, previously set by wpa_supplicant_set_wep_keys(), to be cleared at the driver level.

A possible workaround is to add WPA_DRIVER_FLAGS_SET_KEYS_AFTER_ASSOC to capa.flags, so the wep keys are set again a bit later after wpa_drv_associate() has been called, in function wpa_supplicant_associate(), around line 1104.

This bug causes a problem when sharing a wifi connection in ad-hoc mode with the NetworkManager, with wep enabled. The first attempt to setup the connection creates an ad-hoc network with encryption disabled (confirmed by iwlist scan from another box, and by the output of iwconfig wlan0), the second attempt to setup the same connection works, but for a reason that I could not identify, the peers that try to connect fail to obtain a dhcp lease, although the dhcp server receives queries, and correctly sends replies to these queries.

Ugh.  Need upstream guidance on this.
