* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_hwsim: add fake hw scan handlerJohannes Berg2010-02-081-1/+43
| | | | | | | | | | | | | | | For debugging hardware scan trigger/complete functionality, it was useful to have code in hwsim that pretends to do a hardware scan. This code could be extended to actually do the scan, but for now it was sufficient for me to only pretend. Since hwsim was written to ease debugging, it only makes sense to add it to it permanently.

* cfg80211: export multiple MAC addresses in sysfsJohannes Berg2010-01-221-1/+7
| | | | | | | | | | | | | | | | | | | | If a device has multiple MAC addresses, userspace will need to know about that. Similarly, if it allows the MAC addresses to vary by a bitmask. If a driver exports multiple addresses, it is assumed that it will be able to deal with that many different addresses, which need not necessarily match the ones programmed into the device; if a mask is set then the device should deal addresses within that mask based on an arbitrary "base address". To test it all and show how it is used, add support to hwsim even though it can't actually deal with addresses different from the default.

* mac80211: allow configure_filter callback to sleepJohannes Berg2009-08-201-3/+1
| | | | | | | | | | | | | | | | | | | | | Over time, a whole bunch of drivers have come up with their own scheme to delay the configure_filter operation to a workqueue. To be able to simplify things, allow configure_filter to sleep, and add a new prepare_multicast callback that drivers that need the multicast address list implement. This new callback must be atomic, but most drivers either don't care or just calculate a hash which can be done atomically and then uploaded to the hardware non-atomically. A cursory look suggests that at76c50x-usb, ar9170, mwl8k (which is actually very broken now), rt2x00, wl1251, wl1271 and zd1211 should make use of this new capability.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a new NL80211_CMD_TESTMODE for testing and calibration use with nl80211. There's no multiplexing like like iwpriv had, and the command is not available by default, it needs to be explicitly enabled in Kconfig and shouldn't be enabled in most kernels. The command requires a wiphy index or interface index to identify the device to operate on, and the new TESTDATA attribute. There also is API for sending replies to the command, and testmode multicast messages (on a testmode multicast group). I've also updated mac80211 to be able to pass through the command to the driver, since it itself doesn't implement the testmode command. Additionally, to give people an idea of how to use the command, I've added a little code to hwsim that makes use of the new command to set the powersave mode, this is currently done via debugfs and should remain there, and the testmode command only serves as an example of how to use this best -- with nested netlink attributes in the TESTDATA attribute. A hwsim testmode tool can be found at http://git.sipsolutions.net/hwsim.git/. This tool is BSD licensed so people can easily use it as a basis for their own internal fabrication and validation tools.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: tell driver when idleJohannes Berg2009-05-061-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we aren't doing anything in mac80211, we can turn off much of the hardware, depending on the driver/hw. Not doing anything, aka being idle, means: * no monitor interfaces * no AP/mesh/wds interfaces * any station interfaces are in DISABLED state * any IBSS interfaces aren't trying to be in a network * we aren't trying to scan By creating a new function that verifies these conditions and calling it at strategic points where the states of those conditions change, we can easily make mac80211 tell the driver when we are idle to save power. Additionally, this fixes a small quirk where a recalculated powersave state is passed to the driver even if the hardware is about to stopped completely. This patch intentionally doesn't touch radio_enabled because that is currently implemented to be a soft rfkill which is inappropriate here when we need to be able to wake up with low latency. One thing I'm not entirely sure about is this: phy0: device no longer idle - in use wlan0: direct probe to AP 00:11:24:91:07:4d try 1 wlan0 direct probe responded wlan0: authenticate with AP 00:11:24:91:07:4d wlan0: authenticated > phy0: device now idle > phy0: device no longer idle - in use wlan0: associate with AP 00:11:24:91:07:4d wlan0: RX AssocResp from 00:11:24:91:07:4d (capab=0x401 status=0 aid=1) wlan0: associated Is it appropriate to go into idle state for a short time when we have just authenticated, but not associated yet? This happens only with the userspace SME, because we cannot really know how long it will wait before asking us to associate. Would going idle after a short timeout be more appropriate? We may need to revisit this, depending on what happens. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This is rather confusing, even though the former is used when we beacon ourselves and the latter when we are associated to an AP. This just deprecates the hw.conf.beacon_int setting in favour of always using vif.bss_info.beacon_int. Since it touches all the beaconing IBSS code anyway, we can also add support for the cfg80211 IBSS beacon interval configuration easily. NOTE: The hw.conf.beacon_int setting is retained for now due to drivers still using it -- I couldn't untangle all drivers, some are updated in this patch.

| | | | | | | | | | | | | | | | | | This patch removes all the virtual A-MPDU-queue bookkeeping from mac80211. Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts.

| | | | | | | | | | | This patch replaces the newly introduced sta_notify_ps function, which can be used to notify the driver about every power state transition for all associated stations, by integrating its functionality back into the original sta_notify callback.

* mac80211_hwsim: Add support for client PS modeJouni Malinen2008-11-101-0/+184
| | | | | | | | | | | | | | | | | | | | | | | | This introduces a debugfs file (ieee80211/phy#/hwsim/ps) that can be used to force a simulated radio into power save mode. Following values can be written into this file to change PS mode: 0 = power save disabled (constantly awake) 1 = power save enabled (drop all frames; do not send PS-Poll) 2 = power save enabled (send PS-Poll frames automatically to receive buffered unicast frames); not yet fully implemented 3 = manual PS-Poll trigger (send a single PS-Poll frame) Two different behavior for power save mode processing can be tested: - move between modes 1 and 0 (i.e., receive all buffered frames at a time) - move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps' debugfs file) to fetch power save buffered frames one at a time Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but eventually, it should take a look at TIM IE and send PS-Poll if a traffic bit is set for our AID.

* mac80211_hwsim: Make sure beacon_timer gets deletedJouni Malinen2008-11-101-0/+1
| | | | | | | | | It was possible to trigger a kernel panic because beacon_timer may not have been deleted in all cases when the kernel module was removed while hostapd was still running.
