2014-11-19mac80211: allow drivers to support NL80211_SCAN_FLAG_RANDOM_ADDRJohannes Berg
Allow drivers to support NL80211_SCAN_FLAG_RANDOM_ADDR with software based scanning and generate a random MAC address for them for every scan request with the flag. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-11-10mac80211: add back support for radiotap vendor namespace dataJohannes Berg
Radiotap vendor namespace data might still be useful, but we reverted it because it used too much space in the RX status. Put it back, but address the space problem by using a single bit only and putting everything else into the skb->data. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-10-31mac80211-hwsim: Provide multicast event for HWSIM_CMD_DEL_RADIOJukka Rissanen
When deleting old radio via HWSIM_CMD_DEL_RADIO then listeners on the multicast group "config" are informed. Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-10-31mac80211-hwsim: Provide multicast event for HWSIM_CMD_NEW_RADIOJukka Rissanen
When adding new radio via HWSIM_CMD_NEW_RADIO then listeners on the multicast group "config" are informed. While at it, refactor the configuration parameters to be able to pass them directly and have fewer function arguments.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== pull request: wireless-next 2014-07-25 Please pull this batch of updates intended for the 3.17 stream! For the mac80211 bits, Johannes says: "We have a lot of TDLS patches, among them a fix that should make hwsim tests happy again. The rest, this time, is mostly small fixes." For the Bluetooth bits, Gustavo says: "Some more patches for 3.17. The most important change here is the move of the 6lowpan code to net/6lowpan. It has been agreed with Davem that this change will go through the bluetooth tree. The rest are mostly clean up and fixes." and, "Here follows some more patches for 3.17. These are mostly fixes to what we've sent to you before for next merge window." For the iwlwifi bits, Emmanuel says: "I have the usual amount of BT Coex stuff. Arik continues to work on TDLS and Ariej contributes a few things for HS2.0. I added a few more things to the firmware debugging infrastructure. Eran fixes a small bug - pretty normal content." And for the Atheros bits, Kalle says: "For ath6kl me and Jessica added support for ar6004 hw3.0, our latest version of ar6004. For ath10k Janusz added a printout so that it's easier to check what ath10k kconfig options are enabled. He also added a debugfs file to configure maximum amsdu and ampdu values. Also we had few fixes as usual." On top of that is the usual large batch of various driver updates -- brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action. Rafał has also been very busy with b43 and related updates. Also, I pulled the wireless tree into this in order to resolve a merge conflict... P.S. The change to fs/compat_ioctl.c reflects a name change in a Bluetooth header file... ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-06-25mac80211: support more than one band in scan requestDavid Spinadel
Some drivers (such as iwlmvm) can handle multiple bands in a single HW scan request. Add a HW flag to indicate that the driver support this. To hold the required data, create a separate structure for HW scan request that holds cfg scan request and data about different parts of the scan IEs. As this changes the mac80211 API, update all drivers using it to use the correct new function type/argument.

mac80211 takes care of all the needed steps for hwsim, so indicate support for this capability. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-04-09mac80211: add vif to flush callEmmanuel Grumbach
This will allow the low level driver to make decision based on the vif such as queues etc... Since the vif might be NULL, we can't add it to the tracing functions.

2014-02-11mac80211_hwsim: allow creation of single-channel radios with chanctxLuciano Coelho
Add a new HWSIM_ATTR_USE_CHANCTX attribute to the HWSIM_CMD_CREATE_RADIO command to allow the creation of radios with one channel that use channel contexts. If this attribute is not present, the behaviour is the same as before (ie. single channel radios don't use channel contexts and multi channel radios do).

2014-02-07mac80211_hwsim: fix number of channels in interface combinationsJohannes Berg
There's little point in setting the number of channels if the entire combination struct is overwritten again later - that was clearly intended the other way around, fix it. Reported-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-02-06mac80211: remove unused radiotap vendor fields in ieee80211_rx_statusEmmanuel Grumbach
The purpose of this housekeeping is to make some room for VHT flags. The radiotap vendor fields weren't in use. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-02-04mac80211_hwsim: add channel switch supportAndrei Otcheretianski
Advertise to mac80211 that we can do channel switch both for STA and AP/GO. After each beacon transmission check if CSA is done and call ieee80211_csa_finish if needed. Signed-off-by: Andrei Otcheretianski <andrei.otcheretianski@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-02-04mac80211_hwsim: make P2P-Device support optionalJohannes Berg
When creating new devices, allow P2P-Device support to be turned off to be able to test default behaviour with and without the support. Also add a module parameter for the default setting. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-02-04mac80211_hwsim: make netlink policy constJohannes Berg
The netlink policy in hwsim should be const, there's no reason for it not to be. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2014-01-10mac80211_hwsim: restore regulatory testing functionalityJohannes Berg
Restore the original regulatory testing functionality and also make it more flexible by allowing the parameters to be specified when creating a dynamic radio. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: allow creating/destroying radios on the flyJohannes Berg
Add new commands to the hwsim generic netlink family to allow creating and destroying radios on the fly. The number of channels a radio supports can be specified when it's created, if it isn't the module parameter will be used as default. This should be extended in the future to allow other parameters to be specified, e.g. * list of channels * interface combinations, particularly P2P_DEVICE support * regtest * and pretty much all other hardware capabilities Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: register netlink even with multi-channelJohannes Berg
Reject wmediumd registrations when any devices have multi-channel capability, but register the generic netlink family unconditionally to make it possible to add new commands that shouldn't depend on the number of (default) channels. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: verify wmediumd socketJohannes Berg
There can't be two wmediumd instances controlling hwsim, so reject registration from a second one and verify in the commands that it's the correct instance calling. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: shuffle code to prepare for dynamic radiosJohannes Berg
This will make the next patch, adding support for netlink, smaller and more readable. The code is not modified here. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: minor netlink cleanupsJohannes Berg
Use u8 pointer instead of the struct mac_address and do some other small cleanups. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: assign index from separate counterJohannes Berg
To later allow dynamic registration, assign the index for the struct device and MAC address from a new free-running counter. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: minimize rctbl module parameter usageJohannes Berg
Check the flag that the module parameter sets instead, so later radios can use different parameters. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: refactor radio cleanupJohannes Berg
Refactor the radio cleanup into a new function to later allow deleting a single radio from the list. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: refactor radio registrationJohannes Berg
In order to support dynamic radio registration in the future, refactor the actual registration into a new function with only minor cleanups. Since it had to change anyway, also clean up the init error paths. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: remove regtest for nowJohannes Berg
The regtest thing worked based on the radio loop, but with more dynamic radio registration that loop won't really exist as is. We can add it back later with proper dynamic code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: prepare for different channel supportJohannes Berg
Prepare the code to support, in theory, different devices with a different number of channels supported. Right now this doesn't really change anything, but will allow for dynamic device registration in the future. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-10mac80211_hwsim: clean up netlink exit codeJohannes Berg
There's no need to print a message, and genl_unregister_family() can't really fail so remove the error message there as well. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-07mac80211: remove channel_change_timeJohannes Berg
This value is no longer used by mac80211, and practically no driver ever set it to a correct value anyway, so remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-12-16mac80211_hwsim: Fix NULL pointer dereferenceJavier Lopez
mac80211_hwsim was crashing when receiving tx information from user space. Crash happens because txi->rate_driver_data[0] is pointing to a non valid memory address. This code path is only used by wmediumd and wmediumd doesn't provide multiple channel support, so we can pass the channel struct (data2->channel) directly to mac80211_hwsim_monitor_ack function.
