* mac80211: verify info->control.vif is not NULLJohannes Berg2009-07-292-0/+18
| | | | | | | | | | | | | | | | | When enqueuing packets on the internal packet queue, we need to ensure that we have a valid vif pointer since that is required since the net namespace work. Add some assertions to verify this, but also don't crash is for some reason we don't end up with a vif pointer -- warn and drop the packet in all these cases. Since this code touches a number of hotpaths, it is intended to be temporary, or maybe configurable in the future, at least the bit that is in the path that gets hit for every packet, ieee80211_tx_pending().

| | | | | | | | | | | Jouni and Maxim reported an oops when using wpa_supplicant -Dnl80211, which seems to be due to random data being contained in the crypto settings for the assoc() command.

| | | | | | | | | | | | | | | | Marcel reported a warning, which quite obviously comes from an oversight in the code handling deauth frames, and which resulted in multiple follow-up warnings due to this missing handling. This patch adds the missing deauth handling (telling cfg80211 about it) and also removes the follow-up warnings since they could happen due to races even if nothing is wrong.

| | | | | | | | | | | | | | | | | | | | | | | | | | The current command sending in iwlwifi is a bit of a mess: 1) there is a struct, iwl_cmd, that contains both driver and device data in a single packed structure -- this is very confusing 2) the on-stack data and the command metadata share a structure by embedding the latter in the former, which is also rather confusing because it leads to weird unions and similarly odd constructs 3) each txq always has enough space for 256 commands, even if only 32 end up being used This patch fixes these things: 1) rename iwl_cmd to iwl_device_cmd and keep track of command metadata and device command separately, in two arrays in each tx queue 2) remove the 'meta' member from iwl_host_cmd and only put in the required members 3) allocate the cmd/meta arrays separately instead of embedding them into the txq structure Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* mac80211: fix MLME issuing of probe requests while scanningLuis R. Rodriguez2009-07-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were issuing probe requests to the associated AP on the wrong band by having our beacon timer loss trigger while we are scanning. When we would scan the timer could hit and force us to send a probe request to the AP but with a chance we'd be on the wrong band. This leads to finding no usable bitrate but we should not get so far on the xmit path. We should not be trying to send these probe request frames so prevent ieee80211_mgd_probe_ap() from sending these. As it turns out all callers of ieee80211_mgd_probe_ap() need this check so we just move the scan check there. This means we can remove the recenlty added check during ieee80211_sta_monitor_work(). Additionally we now fix a race condition added by the patch "mac80211: do not monitor the connection while scanning" which had the same check in ieee80211_sta_conn_mon_timer(). The race happens because the timer routine *does* a valid check for scanning but after it queues work into the mac80211 workqueue the work callback can kick off with scanning enabled and cause the same issue we were trying to avoid. The more appropriate solution would be to disable the respective timers during scan and re-enable them after scan but requires more complex code and testing.

While "SCAN_SW_SCANNING" is set during the whole scan "SCAN_OFF_CHANNEL" is set when leaving the operating channel and unset when coming back. Introduce two new scan states "SCAN_LEAVE_OPER_CHANNEL" and "SCAN_ENTER_OPER_CHANNEL" which basically implement the functionality we need to leave the operating channel (send a nullfunc to the AP and stop the queues) and enter it again (send a nullfunc to the AP and start the queues again). Enhance the scan state "SCAN_DECISION" to switch back to the operating channel after each scanned channel. In the future it sould be simple to enhance the decision state to scan as much channels in a row as the qos latency allows us.

* rt2x00: Don't alter rt2x00dev->default_antLars Ericsson2009-07-274-10/+10
| | | | | | | | | | | | | rt2x00dev->default_ant should be initialized once by the driver, and should not be changed afterwards. Because rt2x00lib_config_antenna() was using a reference to the struct antenna_setup it actually had the oppurtunity to change the default antenna setting and it actually did that during the validation. Instead of passing a pointer to antenna_setup the entire structure should be copied.

* mac80211: allow using network namespacesJohannes Berg2009-07-272-0/+2
| | | | | | | | | This finally opens up the ability to put mac80211 devices into different network namespaces. As long as you don't have sysfs, that is. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* cfg80211: make aware of net namespacesJohannes Berg2009-07-279-99/+272
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to make cfg80211/nl80211 aware of network namespaces, we have to do the following things: * del_virtual_intf method takes an interface index rather than a netdev pointer - simply change this * nl80211 uses init_net a lot, it changes to use the sender's network namespace * scan requests use the interface index, hold a netdev pointer and reference instead * we want a wiphy and its associated virtual interfaces to be in one netns together, so - we need to be able to change ns for a given interface, so export dev_change_net_namespace() - for each virtual interface set the NETIF_F_NETNS_LOCAL flag, and clear that flag only when the wiphy changes ns, to disallow breaking this invariant * when a network namespace goes away, we need to reparent the wiphy to init_net * cfg80211 users that support creating virtual interfaces must create them in the wiphy's namespace, currently this affects only mac80211 The end result is that you can now switch an entire wiphy into a different network namespace with the new command iw phy#<idx> set netns <pid> and all virtual interfaces will follow (or the operation fails).

* mac80211: cooperate more with network namespacesJohannes Berg2009-07-273-47/+46
| | | | | | | | | | | | | | | | | | | | | | | There are still two places in mac80211 that hardcode the initial net namespace (init_net). One of them is mandated by cfg80211 and will be removed by a separate patch, the other one is used for finding the network device of a pending packet via its ifindex. Remove the latter use by keeping track of the device pointer itself, via the vif pointer, and avoid it going stale by dropping pending frames for a given interface when the interface is removed. To keep track of the vif pointer for the correct interface, change the info->control.vif pointer's internal use to always be the correct vif, and only move it to the vif the driver expects (or NULL for monitor interfaces and injected packets) right before giving the packet to the driver.
