#1648: No bssid validation in ADHOC mode ------------------------------------+--------------------------------------- Reporter: [EMAIL PROTECTED] | Type: defect Status: new | Priority: critical Component: madwifi: 802.11 stack | Version: v0.9.3.3 Keywords: adhoc bssid validation | Patch_attached: 1 ------------------------------------+--------------------------------------- There is no BSSID validation when an interface is configured in ADHOC mode. So, under some conditions, an host accepts IP packets even if they have been sent by hosts with different ESSID and BSSID.
You can reproduce this problem this way: - Configure two adhoc hosts with different ESSID and BSSID; - Set IP addresses of the same network to these hosts; - On both hosts set a static entry in the ARP table with the MAC of the other host; - Now you can ping or generate any kind of traffic between these hosts, even if they belong to different adhoc cells (they have different BSSID). I suggest a patch to correct this problem (attached, based on 0.9.3.3). It works but I'm not sure if it's 100% correct. -- Ticket URL: <http://madwifi.org/ticket/1648> madwifi.org <http://madwifi.org/> Multiband Atheros Driver for Wireless Fidelity ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
