2014-02-05mac80211_hwsim: make netlink policy constJohannes Berg1-1/+1
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 Berg1-3/+215
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 Berg1-6/+54
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 Berg1-8/+16
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 Berg1-0/+9
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 Berg1-413/+413
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 Berg1-41/+23
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 Berg1-2/+8
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 Berg1-3/+3
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 Berg1-14/+18
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 Berg1-230/+225
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 Berg1-220/+0
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 Berg1-31/+36
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 Berg1-7/+1
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>
2014-01-08mac80211: remove channel_change_timeJohannes Berg1-1/+0
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>
2014-01-07mac80211_hwsim: fix a print messageJohannes Berg1-1/+1
The prefix should be mac80211_hwsim, not mac_80211_hwsim. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-12-17mac80211_hwsim: Fix NULL pointer dereferenceJavier Lopez1-1/+1
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.

The beacon timers really shouldn't use any clock that is subject to adjustments from userspace, particularly not CLOCK_REALTIME. Use CLOCK_MONOTONIC_RAW instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

These two flags are used for the same purpose, just combine them into a no-ir flag to annotate no initiating radiation is allowed. Old userspace sending either flag will have it treated as the no-ir flag. To be considerate to older userspace we also send both the no-ir flag and the old no-ibss flags. Newer userspace will have to be aware of older kernels.

2013-11-25mac80211_hwsim: Fix bcn_en_iter to use atomic iterationJouni Malinen1-1/+1
'mac80211_hwsim: Fix tracking of beaconing for multi-vif' introduced an iteration of active interfaces into the bss_info_changed handler. However, it used a wrong type of iteration and could result in a dead lock since iflist_mtx can already be held. Fix this by using the atomic version of the iteration function.

2013-11-25mac80211_hwsim: Fix radiotap header for ACK framesJouni Malinen1-3/+11
The earlier addition of rt_tsft to struct hwsim_radiotap_hdr updated only mac80211_hwsim_monitor_tx() to fill in the new field. mac80211_hwsim_monitor_ack() did not set the rt_tsft field and as such, leaked eight bytes of kernel memory to user space. In addition, the resulting radiotap header is invalid since the field offsets do not match. Fix these issues by defining a separate radiotap header structure for the ACK frame case which does not use all the fields.

2013-11-20genetlink: only pass array to genl_register_family_with_ops()Johannes Berg1-2/+1
As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)

2013-10-28mac80211_hwsim: Fix tracking of beaconing for multi-vifJouni Malinen1-3/+24
mac80211_hwsim canceled beacon_timer on any vif changing from enabled to disabled beaconing. This breaks cases where there are multiple beaconing vifs and only one of them is removed.

This eliminates "TX" path delay, which shows up as a constant error in Toffset. Get the global TSF once before iterating over all RX HWs, so they all set a mactime with the same time base.
