* mac80211: fix SMPS debugfs lockingJohannes Berg2011-04-201-2/+2
| | | | | | | | | | | | | | | The locking with SMPS requests means that the debugs file should lock the mgd mutex, not the iflist mutex. Calls to __ieee80211_request_smps() need to hold that mutex, so add an assertion. This has always been wrong, but for some reason never been noticed, probably because the locking error only happens while unassociated.

* mac80211: Add testing functionality for TKIPJouni Malinen2011-02-031-1/+101
| | | | | | | | | | | | | | | | | | | | | | 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.

* | net/wireless: use generic_file_llseek in debugfsArnd Bergmann2010-09-161-0/+1
|/ | | | | | | | | | | | | | | | | | | | The default llseek operation is changing from default_llseek to no_llseek, so all code relying on the current behaviour needs to make that explicit. The wireless driver infrastructure and some of the drivers make use of generated debugfs files, so they cannot be converted by our script that automatically determines the right operation. All these files use debugfs and they typically rely on simple_read_from_buffer, so the best llseek operation here is generic_file_llseek. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: "John W.

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.

* cfg80211/mac80211: Use more generic bitrate mask for rate controlJouni Malinen2010-01-121-10/+12
| | | | | | | | | | | | | | | | | | | | | | 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: generalise work handlingJohannes Berg2009-12-281-2/+0
| | | | | | | | | | | | | | | | | | | | | | | In order to use auth/assoc for different purposes other than MLME, it needs to be split up. For other purposes, a generic work handling (potentially on another channel) will be useful. To achieve that, this patch moves much of the MLME work handling out of mlme into a new work API. The API can currently handle probing a specific AP, authentication and association. The MLME previously handled probe/authentication as one step and will continue to do so, but they are separate in the new work handling. Work items are RCU-managed to be able to check for existence of an item for a specific frame in the RX path, but they can be re-used which the MLME right now will do for its combined probe/auth step.

* mac80211: reduce reliance on netdevJohannes Berg2009-12-211-50/+5
| | | | | | | | | | | | | | | | | | | 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.

Then also make mac80211 use debugfs_remove_recursive() where necessary -- it need not remove per-wiphy files as cfg80211 now removes those, but netdev etc. files still need to be handled but can now be removed without needing struct dentry pointers to all of them.

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.

| | | | | | | | | | | | | | | | Previous version was using incorrect union structures for non-AP interfaces when adding and removing max_ratectrl_rateidx and force_unicast_rateidx entries.

* mac80211: make master netdev handling saneJohannes Berg2008-07-141-7/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

That could be exploited by any user if the user is able to open debugfs files and can cause networking devices, STA entries or similar to disappear which is quite easy to do. Hence, all debugfs files should be root-only. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: remove port control enable switch, clean up sta flagsJohannes Berg2008-02-291-9/+0
| | | | | | | | | | | | | | | This patch removes the 802.1X port acess control enable flag since it is not required. Instead, set the authorized flag for each station that we normally communicate with (WDS peers, IBSS peers and APs we're associated to) and require hostapd to set the authorized flag for all stations when port control is not enabled. Also, since I was working in that area, this documents station flags and removes the unused "permanent" one. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: add unified BSS configurationJohannes Berg2008-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch (based on Ron Rindjunsky's) creates a framework for a unified way to pass BSS configuration to drivers that require the information, e.g. for implementing power save mode. This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change.

* mac80211: add beacon configuration via cfg80211Johannes Berg2008-01-281-27/+0
| | | | | | | | | | This patch implements the cfg80211 hooks for configuring beaconing on an access point interface in mac80211. While doing so, it fixes a number of races that could badly crash the machine when the beacon is changed while being requested by the driver.

* mac80211: move interface type to vif structureJohannes Berg2008-01-281-2/+2
| | | | | | | | | | Drivers that support mixed AP/STA operation may well need to know the type of a virtual interface when iterating over them. The easiest way to support that is to move the interface type variable into the vif structure. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: clean up eapol frame handling/port controlJohannes Berg2008-01-281-18/+9
| | | | | | | | | | | | | | | | | This cleans up the eapol frame handling and some related code in the receive and transmit paths. After this patch * EAPOL frames addressed to us or the EAPOL group address are always accepted regardless of whether they are encrypted or not * other frames from a station are dropped if PAE is enabled and the station is not authorized * unencrypted frames (except the EAPOL frames above) are dropped if drop_unencrypted is enabled * some superfluous code that eth_type_trans handles anyway is gone * port control is done for transmitted packets Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* [PATCH] mac80211: validate VLAN interfaces betterJohannes Berg2007-10-101-5/+0
| | | | | | | | | | | | | This patch changes mac80211 to verify that VLAN interfaces are valid and not bother drivers about them any more. VLAN interfaces are now only valid when an AP interface is up with the same MAC address, and are automatically turned off when the AP interface is set down.

* [PATCH] mac80211: revamp interface and filter configurationJohannes Berg2007-10-101-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
