| * nl80211: sanity check the channel switch counter valueLuciano Coelho2014-10-091-1/+9
| | | | | | | | | | | | | | | | | | | | | | The nl80211 channel switch count attribute (NL80211_ATTR_CH_SWITCH_COUNT) is specified as u32, but the specification uses u8 for the counter. To make sure strange things don't happen without informing the user, sanity check the value and return -EINVAL if it doesn't fit in u8.

* | lib80211: remove unused print_ssid()Andy Shevchenko2014-10-141-32/+0
|/ | | | | | | | | | | | | | | | | | | | | In kernel we have %*pE specifier to print an escaped buffer. All users now switched to that approach. This fixes a bug as well. The current implementation wrongly prints octal numbers: only two first digits are used in case when 3 are required and the rest of the string ends up cut off. Additionally by default the \f, \v, \a, and \e are escaped to their alphabetic representation. It's safe to do since it is currently used for messaging only.

Linville says: ==================== pull request: wireless-next 2014-09-22 Please pull this batch of updates intended for the 3.18 stream... For the mac80211 bits, Johannes says: "This time, I have some rate minstrel improvements, support for a very small feature from CCX that Steinar reverse-engineered, dynamic ACK timeout support, a number of changes for TDLS, early support for radio resource measurement and many fixes. Also, I'm changing a number of places to clear key memory when it's freed and Intel claims copyright for code they developed." For the bluetooth bits, Johan says: "Here are some more patches intended for 3.18. Most of them are cleanups or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed channels which should now work better together with the L2CAP information request procedure." For the iwlwifi bits, Emmanuel says: "I fix here dvm which was broken by my last pull request. Arik continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal keeps digging into rate scaling code, more to come soon. Besides this, nothing really special here." Beyond that, there are the usual big batches of updates to ath9k, b43, mwifiex, and wil6210 as well as a handful of other bits here and there. Also, rtlwifi gets some btcoexist attention from Larry. Please let me know if there are problems! ==================== Had to adjust the wil6210 code to comply with Joe Perches's recent change in net-next to make the netdev_*() routines return void instead of 'int'.

The API calls for userspace doing the action frame handshake with the peer, and then allows only to set up the parameters in the driver.

This causes the code for CONFIG_NETLINK_MMAP to get confused, because it takes ownership of the skb cb data when the SKB is handed off to netlink, and it doesn't explicitly clear it. Clear the skb cb explicitly when we're done and before it gets passed to netlink to avoid this issue.

But, memory get allocated under spin_lock_bh(), this implies atomic context. So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake), and it should be this way or warning triggered in the memory allocation code.

| * cfg80211: allow RSSI compensationEmmanuel Grumbach2014-05-221-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The firmware / low level driver can parse the channel in the DS IE or HT IE and compensate the RSSI so that it will still have a valid value even if we heard the frame on an adjacent channel. This can be done up to a certain offset. Add this offset as a configuration for the low level driver. A low level driver that can compensate the low RSSI in this case should assign the maximal offset for which the RSSI value is still valid.

| | | | | | | | | | | | | | | | | | | | | | | | Implement and export the new cfg80211_get_station() API. This utility can be used by other kernel modules to obtain detailed information about a given wireless station. It will be in particular useful to batman-adv which will implement a wireless rate based metric.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users may need information about the expected throughput towards a given peer. This value is supposed to consider the size overhead generated by the 802.11 header. This value is exported in kbps through the get_station() API by including it into the station_info object. Moreover, it is sent to user space when replying to the nl80211 GET_STATION command. This information will be useful to the batman-adv module which will use it for its new metric computation.

| * cfg80211: constify wowlan/coalesce mask/pattern pointersJohannes Berg2014-05-191-17/+22
| | | | | | | | | | | | | | | | This requires changing the nl80211 parsing code a bit to use intermediate pointers for the allocation, but clarifies the API towards the drivers. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * cfg80211: constify more pointers in the cfg80211 APIJohannes Berg2014-05-193-3/+4
| | | | | | | | | | | | | | | | | | | | This also propagates through the drivers. The orinoco driver uses the cfg80211 API structs for internal bookkeeping, and so needs a (void *) cast that removes the const - but that's OK because it allocates those pointers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the type of NL80211_ATTR_CSA_C_OFF_BEACON and NL80211_ATTR_CSA_C_OFF_PRESP to be NLA_BINARY which allows userspace to use beacons and probe responses with multiple CSA counters. This isn't breaking the API since userspace can continue to use nla_put_u16 for this attributes, which is equivalent to a single element u16 array. In addition advertise max number of supported CSA counters. This is needed when using CSA and eCSA IEs together.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add NL80211_ATTR_CSA_C_OFFSETS_TX which holds an array of offsets to the CSA counters which should be updated when sending a management frames with NL80211_CMD_FRAME. This API should be used by the drivers that wish to keep the CSA counter updated in probe responses, but do not implement probe response offloading and so, do not use ieee80211_proberesp_get function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need to pass NL80211_IFTYPE_UNSPECIFIED when calling cfg80211_chandef_dfs_required() since we always already have the interface type. So, pass the actual interface type instead. Additionally, have cfg80211_chandef_dfs_required() WARN if the passed interface type is NL80211_IFTYPE_UNSPECIFIED, so we can detect problems more easily.
