With this patch, scanning with mshX interface will only return mesh networks. To differentiate them, a specific mesh IE in beacons/probe responses is used. This IE has been introduced in firmware release 5.110.14. Note: Even though there can be at most a single mesh per channel, this scan might return several networks in the same channel. If all nodes in a mesh network are associated to an AP, they won't produce beacons/probe responses, thus the network will not be listed. This will be fixed in future firmware releases. Scan on ethX interface is not filtered, so it will list both mesh and non-mesh networks. Signed-off-by:

Remove struct IE_WPA and just use direct checking of the IE bytes like ipw. Remove WLAN_802_11_VARIABLE_IEs because it's unused. Kill ieeetypes_elementid enum and just use MFIE_* from ieee80211.h. Also use struct ieee80211_info_element for scan buffer processing to simplify pointer usage. Signed-off-by:

Replacing accesses to dev->priv to netdev_priv(dev). The replacment is safe when netdev_priv is used to access a private structure that is right next to the net_device structure in memory. Cf http://groups.google.com/group/comp.os.linux.development.system/browse_thread/thread/de19321bcd94dbb8/0d74a4adcd6177bd This is the case when the net_device structure was allocated with a call to alloc_netdev or one of its derivative.

Currently the modinfo looks like: description: Support for Cisco/Aironet 802.11 wireless ethernet cards. Direct support for ISA/PCI/MPI cards and support for PCMCIA when used with airo_cs. Arguably, it should be cut at the end of the first sentence. This at least makes it somewhat more legible. Signed-off-by:

While in monitor mode the zd1211rw received only a limited set of packets. This patch forwards now all packets the device receives. Notify that while monitoring no FCS checks are done; so strange packets might appear in the network sniffer of your choice. ATTENTION: Support for multiple interfaces on a single ZD1211 device is currently broken. So this code works only on the first interface. Here is an example to put the device in monitor mode. iwconfig wlan0 mode monitor ifconfig wlan0 up iwconfig wlan0 channel 10 [dsd@gentoo.org: backport to mainline] Signed-off-by:

The TKIP mixing code was added for the benefit of Intel's ipw3945 chipset but that code ended up not using it. We have previously identified many problems with this code and it crystallized that library functions for mixing are likely to handle this in much more generality and might allow b43 to take advantage of hardware acceleration for TKIP. Due to these reasons, remove the TKIP mixing for hardware accelerated crypto operations. Signed-off-by:

This patch makes the mac80211/driver interface rely only on the IEEE80211_TXCTL_DO_NOT_ENCRYPT flag to signal to the driver whether a frame should be encrypted or not, since mac80211 internally no longer relies on HW_KEY_IDX_INVALID either this removes it, changes the key index to be a u8 in all places and makes the full range of the value available to drivers.

No existing drivers use this callback, hence there's no telling how it might be used. In fact, it is unlikely to be of much use as-is because the default key index isn't something that the driver can do much with without knowing which interface it was for etc. And if it needs the key index for the transmitted frame, it can get it by keeping a reference to the key_conf structure and looking it up by hw_key_idx.

This patch removes all mention of the atheros turbo modes that can't possibly work properly anyway since in some places we don't check for them when we should. I have no idea what the iwlwifi drivers were doing with these but it can't possibly have been correct. Cc: Zhu Yi <yi.zhu@intel.com> Signed-off-by:

During receive processing, we select the key long before using it and because there's no locking it is possible that we kfree() the key after having selected it but before using it for crypto operations. Obviously, this is bad. Secondly, during transmit processing, there are two possible races: We have a similar race between select_key() and using it for encryption, but we also have a race here between select_key() and hardware encryption (both when a key is removed.) This patch solves these issues by using RCU: when a key is to be freed, we first remove the pointer from the appropriate places (sdata->keys, sdata->default_key, sta->key) using rcu_assign_pointer() and then synchronize_rcu(). Then, we can safely kfree() the key and remove it from the hardware. There's a window here where the hardware may still be using it for decryption, but we can't work around that without having two hardware callbacks, one to disable the key for RX and one to disable it for TX; but the worst thing that will happen is that we receive a packet decrypted that we don't find a key for any more and then drop it. When we add a key, we first need to upload it to the hardware and then, using rcu_assign_pointer() again, link it into our structures. In the code using keys (TX/RX paths) we use rcu_dereference() to get the key and enclose the whole tx/rx section in a rcu_read_lock() ... rcu_read_unlock() block. Because we've uploaded the key to hardware before linking it into internal structures, we can guarantee that it is valid once get to into tx(). One possible race condition remains, however: when we have hardware acceleration enabled and the driver shuts down the queues, we end up queueing the frame. If now somebody removes the key, the key will be removed from hwaccel and then then driver will be asked to encrypt the frame with a key index that has been removed. Hence, drivers will need to be aware that the hw_key_index they are passed might not be under all circumstances. Most drivers will, however, simply ignore that condition and encrypt the frame with the selected key anyway, this only results in a frame being encrypted with a wrong key or dropped (rightfully) because the key was not valid. There isn't much we can do about it unless we want to walk the pending frame queue every time a key is removed and remove all frames that used it. This race condition, however, will most likely be solved once we add multiqueue support to mac80211 because then frames will be queued further up the stack instead of after being processed.

Kalle Valo noticed that QoS frames are sent with an invalid QoS control field; this is because we increase the header length but neither initialise the space nor actually have enough space in the header structure for the QoS control field. This patch fixes it by treating the QoS field specially and appending it explicitly, initialising it to zero. Signed-off-by:

On loaded/big hosts, rt_check_expire() if of litle use, because it generally breaks out of its main loop because of a jiffies change. It can take a long time (read : timer invocations) to actually scan the whole hash table, freeing unused entries. Converting it to use a workqueue instead of softirq is a nice move because we can allow rt_check_expire() to do the scan it is supposed to do, without hogging the CPU. This has an impact on the average number of entries in cache, reducing ram usage. Cache is more responsive to parameter changes (/proc/sys/net/ipv4/route/gc_timeout and /proc/sys/net/ipv4/route/gc_interval) Note: Maybe the default value of gc_interval (60 seconds) is too high, since this means we actually need 5 (300/60) invocations to scan the whole table.
