From 3b4c7d640376dbccfe80fc4f7b8772ecc7de28c5 Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Mon, 14 Aug 2006 23:12:03 -0700 Subject: [PATCH] kthread: airo.c The airo driver is currently caching a pid for later use, but with the implementation of containers, pids themselves do not uniquely identify a task. The driver is also using kernel_thread() which is deprecated in drivers. This patch essentially replaces the kernel_thread() with kthread_create(). It also stores the task_struct of the airo_thread rather than its pid. Since this introduces a second task_struct in struct airo_info, the patch renames airo_info.task to airo_info.list_bss_task. As an extension of these changes, the patch further: - replaces kill_proc() with kthread_stop() - replaces signal_pending() with kthread_should_stop() - removes thread completion synchronisation which is handled by kthread_stop().

The iwconfig tool works around this behaviour by looking up the frequency from the channel table if a frequency below 1kHz is returned, other tools (e.g. kwlaninfo) don't. According to the comment in the iwconfig source the driver is supposed to return the frequency, not the channel number. Signed-off-by: Ingo van Lil Signed-off-by: Zhu Yi Signed-off-by: John W.

I have tested this patch with iwconfig. It makes ipw2200 compliant with all the cases mentioned in the iwconfig man page. The commands iwconfig iface essid any iwconfig iface essid -- any iwconfig iface essid off iwconfig iface essid on all seemed to work correctly. None of this worked before the patch. Note, this patch treats iwconfig iface essid iwconfig iface essid "" The same. It produces an error message: essid: Unknown host. Since an essid of "" is not mentioned in the iwconfig man page.

For this, I enhanced the ipw_wx_set_scan function in such a way that it differentiates between a passive and an active scan request. Additionally, I added a new function called ipw_request_passive_scan that is similiar to the ipw_request_scan function to perform passive scans. Last but not least, I added a field (in fact it is a work_struct struct) called request_passive_scan to the ipw_priv struct. Signed-off-by: Thomas King Signed-off-by: Zhu Yi Signed-off-by: John W.
