include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

mac80211: Add testing functionality for TKIP TKIP countermeasures depend on devices being able to detect Michael MIC failures on received frames and for stations to report errors to the AP. In order to test that behavior, it is useful to be able to send out TKIP frames with incorrect Michael MIC. This testing behavior has minimal effect on the TX path, so it can be added to mac80211 for convenient use. The interface for using this functionality is a file in mac80211 netdev debugfs (tkip_mic_test). Writing a MAC address to the file makes mac80211 generate a dummy data frame that will be sent out using invalid Michael MIC value. In AP mode, the address needs to be for one of the associated stations or ff:ff:ff:ff:ff:ff to use a broadcast frame. In station mode, the address can be anything, e.g., the current BSSID. It should be noted that this functionality works correctly only when associated and using TKIP.

cfg80211/mac80211: Use more generic bitrate mask for rate control Extend struct cfg80211_bitrate_mask to actually use a bitfield mask instead of just a single fixed or maximum rate index. This change itself does not modify the behavior (except for debugfs files), but it prepares cfg80211 and mac80211 for a new nl80211 command for setting which rates can be used in TX rate control. Since frames are now going through the rate control algorithm unconditionally, the internal IEEE80211_TX_INTFL_RCALGO flag can now be removed. The RC implementations can use the rate_idx_mask value to optimize their behavior if only a single rate is enabled. The old max_rate_idx in struct ieee80211_tx_rate_control is maintained (but commented as deprecated) for backwards compatibility with existing RC implementations. Once these implementations have been updated to use the more generic rate_idx_mask, the max_rate_idx value can be removed.

mac80211: handle TX power per virtual interface Even before channel contexts/multi-channel, having a single global TX power limit was already problematic, in particular if two managed interfaces connected to two APs with different power constraints. The channel context introduction completely broke this though and in fact I had disabled TX power configuration there for drivers using channel contexts. Change everything to track TX power per interface so that different user settings and different channel maxima are treated correctly. Also continue tracking the global TX power though for compatibility with applications that attempt to configure the wiphy's TX power globally. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

mac80211: split IBSS/managed code This patch splits out the ibss code and data from managed (station) mode. The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way. I've also shuffled around some code -- null function sending is only applicable to managed interfaces so put that into that file, some other functions are needed from various places so put them into util, and also rearranged the prototypes in ieee80211_i.h accordingly.

mac80211: implement SMPS for AP When the driver requests to move to STATIC or DYNAMIC SMPS, we send an action frame to each associated station and reconfigure the channel context / driver. Of course, non-MIMO stations are ignored. The beacon isn't updated. The association response will include the original capabilities. Stations that associate while in non-OFF SMPS mode will get an action frame right after association to inform them about our current state. Note that we wait until the end of the EAPOL. Sending an action frame before the EAPOL is finished can be an issue for a few clients. Clients aren't likely to send EAPOL frames in MIMO anyway. When the SMPS configuration gets more permissive (e.g. STATIC -> OFF), we don't wake up stations that are asleep We remember that they don't know about the change and send the action frame when they wake up. When the SMPS configuration gets more restrictive (e.g. OFF -> STATIC), we set the TIM bit for every sleeping STA. uAPSD stations might send MIMO until they poll the action frame, but this is for a short period of time.

mac80211: Add testing functionality for TKIP TKIP countermeasures depend on devices being able to detect Michael MIC failures on received frames and for stations to report errors to the AP. In order to test that behavior, it is useful to be able to send out TKIP frames with incorrect Michael MIC. This testing behavior has minimal effect on the TX path, so it can be added to mac80211 for convenient use. The interface for using this functionality is a file in mac80211 netdev debugfs (tkip_mic_test). Writing a MAC address to the file makes mac80211 generate a dummy data frame that will be sent out using invalid Michael MIC value. In AP mode, the address needs to be for one of the associated stations or ff:ff:ff:ff:ff:ff to use a broadcast frame. In station mode, the address can be anything, e.g., the current BSSID. It should be noted that this functionality works correctly only when associated and using TKIP.

mac80211: mesh power save basics Add routines to - maintain a PS mode for each peer and a non-peer PS mode - indicate own PS mode in transmitted frames - track neighbor STAs power modes - buffer frames when neighbors are in PS mode - add TIM and Awake Window IE to beacons - release frames in Mesh Peer Service Periods Add local_pm to sta_info to represent the link-specific power mode at this station towards the remote station. When a peer link is established, use the default power mode stored in mesh config. Update the PS status if the peering status of a neighbor changes. Maintain a mesh power mode for non-peer mesh STAs. Set the non-peer power mode to active mode during peering. Authenticated mesh peering is currently not working when either node is configured to be in power save mode. Indicate the current power mode in transmitted frames. Use QoS Nulls to indicate mesh power mode transitions. For performance reasons, calls to the function setting the frame flags are placed in HWMP routing routines, as there the STA pointer is already available. Add peer_pm to sta_info to represent the peer's link-specific power mode towards the local station. Add nonpeer_pm to represent the peer's power mode towards all non-peer stations. Track power modes based on received frames. Add the ps_data structure to ieee80211_if_mesh (for TIM map, PS neighbor counter and group-addressed frame buffer). Set WLAN_STA_PS flag for STA in PS mode to use the unicast frame buffering routines in the tx path. Update num_sta_ps to buffer and release group-addressed frames after DTIM beacons. Announce the awake window duration in beacons if in light or deep sleep mode towards any peer or non-peer. Create a TIM IE similarly to AP mode and add it to mesh beacons. Parse received Awake Window IEs and check TIM IEs for buffered frames. Release frames towards peers in mesh Peer Service Periods. Use the corresponding trigger frames and monitor the MPSP status. Append a QoS Null as trigger frame if neccessary to properly end the MPSP. Currently, in HT channels MPSPs behave imperfectly and show large delay spikes and frame losses.

mac80211: move sdata debugfs dir to vif There is need create driver own per interface debugfs files. This is currently done by drv_{add,remove}_interface_debugfs() callbacks. But it is possible that after we remove interface from the driver (i.e. on suspend) we call drv_remove_interface_debugfs() function. Fixing this problem will require to add call drv_{add,remove}_interface_debugfs() anytime we create and remove interface in mac80211. So it's better to add debugfs dir dentry to vif structure to allow to create/remove custom debugfs driver files on drv_{add,remove}_interface().

mac80211: make master netdev handling sane Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

mac80211: Add testing functionality for TKIP TKIP countermeasures depend on devices being able to detect Michael MIC failures on received frames and for stations to report errors to the AP. In order to test that behavior, it is useful to be able to send out TKIP frames with incorrect Michael MIC. This testing behavior has minimal effect on the TX path, so it can be added to mac80211 for convenient use. The interface for using this functionality is a file in mac80211 netdev debugfs (tkip_mic_test). Writing a MAC address to the file makes mac80211 generate a dummy data frame that will be sent out using invalid Michael MIC value. In AP mode, the address needs to be for one of the associated stations or ff:ff:ff:ff:ff:ff to use a broadcast frame. In station mode, the address can be anything, e.g., the current BSSID. It should be noted that this functionality works correctly only when associated and using TKIP.

mac80211: implement SMPS for AP When the driver requests to move to STATIC or DYNAMIC SMPS, we send an action frame to each associated station and reconfigure the channel context / driver. Of course, non-MIMO stations are ignored. The beacon isn't updated. The association response will include the original capabilities. Stations that associate while in non-OFF SMPS mode will get an action frame right after association to inform them about our current state. Note that we wait until the end of the EAPOL. Sending an action frame before the EAPOL is finished can be an issue for a few clients. Clients aren't likely to send EAPOL frames in MIMO anyway. When the SMPS configuration gets more permissive (e.g. STATIC -> OFF), we don't wake up stations that are asleep We remember that they don't know about the change and send the action frame when they wake up. When the SMPS configuration gets more restrictive (e.g. OFF -> STATIC), we set the TIM bit for every sleeping STA. uAPSD stations might send MIMO until they poll the action frame, but this is for a short period of time.

{nl,cfg,mac}80211: Implement RSSI threshold for mesh peering Mesh peer links are established only if average rssi of the peer candidate satisfies the threshold. This is not in 802.11s specification but was requested by David Fulgham, an open80211s user. This is a way to avoid marginal peer links with stations that are barely within range.

mac80211: mesh power save basics Add routines to - maintain a PS mode for each peer and a non-peer PS mode - indicate own PS mode in transmitted frames - track neighbor STAs power modes - buffer frames when neighbors are in PS mode - add TIM and Awake Window IE to beacons - release frames in Mesh Peer Service Periods Add local_pm to sta_info to represent the link-specific power mode at this station towards the remote station. When a peer link is established, use the default power mode stored in mesh config. Update the PS status if the peering status of a neighbor changes. Maintain a mesh power mode for non-peer mesh STAs. Set the non-peer power mode to active mode during peering. Authenticated mesh peering is currently not working when either node is configured to be in power save mode. Indicate the current power mode in transmitted frames. Use QoS Nulls to indicate mesh power mode transitions. For performance reasons, calls to the function setting the frame flags are placed in HWMP routing routines, as there the STA pointer is already available. Add peer_pm to sta_info to represent the peer's link-specific power mode towards the local station. Add nonpeer_pm to represent the peer's power mode towards all non-peer stations. Track power modes based on received frames. Add the ps_data structure to ieee80211_if_mesh (for TIM map, PS neighbor counter and group-addressed frame buffer). Set WLAN_STA_PS flag for STA in PS mode to use the unicast frame buffering routines in the tx path. Update num_sta_ps to buffer and release group-addressed frames after DTIM beacons. Announce the awake window duration in beacons if in light or deep sleep mode towards any peer or non-peer. Create a TIM IE similarly to AP mode and add it to mesh beacons. Parse received Awake Window IEs and check TIM IEs for buffered frames. Release frames towards peers in mesh Peer Service Periods. Use the corresponding trigger frames and monitor the MPSP status. Append a QoS Null as trigger frame if neccessary to properly end the MPSP. Currently, in HT channels MPSPs behave imperfectly and show large delay spikes and frame losses.

mac80211: handle TX power per virtual interface Even before channel contexts/multi-channel, having a single global TX power limit was already problematic, in particular if two managed interfaces connected to two APs with different power constraints. The channel context introduction completely broke this though and in fact I had disabled TX power configuration there for drivers using channel contexts. Change everything to track TX power per interface so that different user settings and different channel maxima are treated correctly. Also continue tracking the global TX power though for compatibility with applications that attempt to configure the wiphy's TX power globally. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way.

mac80211: make master netdev handling sane Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

mac80211: move sdata debugfs dir to vif There is need create driver own per interface debugfs files. This is currently done by drv_{add,remove}_interface_debugfs() callbacks. But it is possible that after we remove interface from the driver (i.e. on suspend) we call drv_remove_interface_debugfs() function. Fixing this problem will require to add call drv_{add,remove}_interface_debugfs() anytime we create and remove interface in mac80211. So it's better to add debugfs dir dentry to vif structure to allow to create/remove custom debugfs driver files on drv_{add,remove}_interface().

mac80211: reduce reliance on netdev For bluetooth 3, we will most likely not have a netdev for a virtual interface (sdata), so prepare for that by reducing the reliance on having a netdev. This patch moves the name and address fields into the sdata struct and uses them from there all over. Some work is needed to keep them sync'ed, but that's not a lot of work and in slow paths anyway. In doing so, this also reduces the number of pointer dereferences in many places, because of things like sdata->dev->dev_addr becoming sdata->vif.addr.

mac80211: clean up debugging There are a few things that make the logging and debugging in mac80211 less useful than it should be right now: * a lot of messages should be pr_info, not pr_debug * wholesale use of pr_debug makes it require *both* Kconfig and dynamic configuration * there are still a lot of ifdefs * the style is very inconsistent, sometimes the sdata->name is printed in front Clean up everything, introducing new macros and separating out the station MLME debugging into a new Kconfig symbol.
