From ea2b26e0a0264650e13acac8e66d315bb818897c Mon Sep 17 00:00:00 2001 From: James Ketrenos Date: Wed, 24 Aug 2005 21:25:16 -0500 Subject: Catch ipw2200 up to equivelancy with v1.0.1 This commit contains the following fixes: Fixed #559: iwconfig rate support (thanks to Florian Hackenberger) Improved link signal quality calculation (thanks to Bill Moss) Fixed a problem with sensitivity threshold during association Added iwpriv for turning forcing long preamble support: % iwpriv eth1 set_preamble 1|0 Fixed #542 and #377 support for short preamble Fixed locked BSSID reporting channel number (thanks to Pedro Ramalhais) Fixed type-o with scan watchdog timeout message (thanks to Pedro Ramalhais) Changed logic for displaying get_mode output so the code is easier to follow (thanks to Pedro Ramalhais) Added initial support for WPA (thanks to Yi Zhu) -- tested with wpa_supplicant (either tip w/ ipw driver, or with -Dipw2100) with both CCMP and TKIP Fixed problem with CCMP not working due to uninitialized 802.11 header fields (thanks to Pedro Ramalhais) Bug references are to defects stored on http://bughost.org Signed-off-by: James Ketrenos --- drivers/net/wireless/ipw2200.c | 1694 +++++++++++++++++++++++++++++----------- 1 file changed, 1232 insertions(+), 462 deletions(-) (limited to 'drivers/net/wireless/ipw2200.c') diff --git a/drivers/net/wireless/ipw2200.c b/drivers/net/wireless/ipw2200.c index 3db0c32afe82..ddbee3edcd8c 100644 --- a/drivers/net/wireless/ipw2200.c +++ b/drivers/net/wireless/ipw2200.c @@ -32,7 +32,7 @@ #include "ipw2200.h" -#define IPW2200_VERSION "1.0.0" +#define IPW2200_VERSION "1.0.1" #define DRV_DESCRIPTION "Intel(R) PRO/Wireless 2200/2915 Network Driver" #define DRV_COPYRIGHT "Copyright(c) 2003-2004 Intel Corporation" #define DRV_VERSION IPW2200_VERSION @@ -44,7 +44,6 @@ MODULE_LICENSE("GPL");

We now add back in as a supported rate any mandatory rate. Fixed #597 kernel oops due to calling dev_kfree_skb on an skb multiple times. Added code to control LEDs that can be controlled through the wireless NIC (vs. non-wireless HW interfaces) -- this is currently disabled by default due to reports by some users of it hanging their laptop. Added some more debug messages around fragmentation logic Added locking around STATUS_HCMD_ACTIVE to prevent re-entry race conditions Moved ipw_adapter_restart to only execute on the priv->workqueue to keep keyboard errors from occuring during adapter restart Added CFG_BACKGROUND_SCAN to easily allow people to play with background scanning implementations Modified WPA logic to send WPA IE if one is set (vs. being based on wpa_enabled) Modified scan result logic to report WPA and RSN IEs if set (vs. being based on wpa_enabled) Fixed issues with endianess compatability between the host and wireless adapter (thanks to York Liu and Yi Zhu) Fixed problem with Ad-Hoc network creation causing a firmware error if a scan was actively running (thanks to Mohamed Abbas) Signed-off-by: James Ketrenos --- drivers/net/wireless/ipw2200.c | 962 +++++++++++++++++++++++++++++++---------- 1 file changed, 725 insertions(+), 237 deletions(-) (limited to 'drivers/net/wireless/ipw2200.c') diff --git a/drivers/net/wireless/ipw2200.c b/drivers/net/wireless/ipw2200.c index ddbee3edcd8c..ea7a3dcf1daa 100644 --- a/drivers/net/wireless/ipw2200.c +++ b/drivers/net/wireless/ipw2200.c @@ -32,7 +32,7 @@ #include "ipw2200.h" -#define IPW2200_VERSION "1.0.1" +#define IPW2200_VERSION "1.0.2" #define DRV_DESCRIPTION "Intel(R) PRO/Wireless 2200/2915 Network Driver" #define DRV_COPYRIGHT "Copyright(c) 2003-2004 Intel Corporation" #define DRV_VERSION IPW2200_VERSION @@ -49,6 +49,7 @@ static int mode = 0;

modprobe -r ipw2200 * Added QoS (CONFIG_IPW_QOS) support. This is being actively developed but is the first step in getting WMM support into the driver and the kernel. * Fixed some race conditions with channel changes, association, and scan abort that could periodically cause a firmware restart. * Added some extensions to export scan and network statistics to user space (exposed through speed_scan and net_stats sysfs entries) * Fixed a few bugs in how monitor mode was supported (scan lists weren't quite right) * Updated the firmware requirement from 2.2 to 2.3 which supports monitor mode.

Because of the frequent channel change, it is possible that when we are try to associate with channel 1 (authenticated but not associated). Another channel change comes at this time, then the driver will issue disassociate command to the firmware which will cause the fatal error. It seems that the association/disassociation procedure should not be interrupted. The patch attached adds test on STATUS_ASSOCIATING | STATUS_DISASSOCIATING in ipw_send_cmd(), when ensures that commands will not be sent to firmware when we are in these two status.
