| | | | | | | | | | | | | | | | | | | | | | | | | | By the time userspace returns with a response to the regulatory domain request, the wiphy causing the request might have gone away. If this is so, reject the update but mark the request as having been processed anyway. Cc: Luis R.

| * cfg80211: fix bug on regulatory core exit on access to last_requestLuis R. Rodriguez2011-11-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added the .uevent() callback for the regulatory device used during the platform device registration. The change was done to account for queuing up udev change requests through udevadm triggers. The change also meant that upon regulatory core exit we will now send a uevent() but the uevent() callback, reg_device_uevent(), also accessed last_request. Right before commiting device suicide we free'd last_request but never set it to NULL so platform_device_unregister() would lead to bogus kernel paging request. Fix this and also simply supress uevents right before we commit suicide as they are pointless. This fix is required for kernels >= v2.6.39 $ git describe --contains 4d9d88d1 v2.6.39-rc1~468^2~25^2^2~21 The impact of not having this present is that a bogus paging access may occur (only read) upon cfg80211 unload time. You may also get this BUG complaint below. Although Johannes could not reproduce the issue this fix is theoretically correct. mac80211_hwsim: unregister radios mac80211_hwsim: closing netlink BUG: unable to handle kernel paging request at ffff88001a06b5ab IP: [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] PGD 1836063 PUD 183a063 PMD 1ffcb067 PTE 1a06b160 Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC CPU 0 Modules linked in: cfg80211(-) [last unloaded: mac80211] Pid: 2279, comm: rmmod Tainted: G W 3.1.0-wl+ #663 Bochs Bochs RIP: 0010:[<ffffffffa030df9a>] [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] RSP: 0000:ffff88001c5f9d58 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff88001d2eda88 RCX: ffff88001c7468fc RDX: ffff88001a06b5a0 RSI: ffff88001c7467b0 RDI: ffff88001c7467b0 RBP: ffff88001c5f9d58 R08: 000000000000ffff R09: 000000000000ffff R10: 0000000000000000 R11: 0000000000000001 R12: ffff88001c7467b0 R13: ffff88001d2eda78 R14: ffffffff8164a840 R15: 0000000000000001 FS: 00007f8a91d8a6e0(0000) GS:ffff88001fc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffff88001a06b5ab CR3: 000000001c62e000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process rmmod (pid: 2279, threadinfo ffff88001c5f8000, task ffff88000023c780) Stack: ffff88001c5f9d98 ffffffff812ff7e5 ffffffff8176ab3d ffff88001c7468c2 000000000000ffff ffff88001d2eda88 ffff88001c7467b0 ffff880000114820 ffff88001c5f9e38 ffffffff81241dc7 ffff88001c5f9db8 ffffffff81040189 Call Trace: [<ffffffff812ff7e5>] dev_uevent+0xc5/0x170 [<ffffffff81241dc7>] kobject_uevent_env+0x1f7/0x490 [<ffffffff81040189>] ? sub_preempt_count+0x29/0x60 [<ffffffff814cab1a>] ? _raw_spin_unlock_irqrestore+0x4a/0x90 [<ffffffff81305307>] ? devres_release_all+0x27/0x60 [<ffffffff8124206b>] kobject_uevent+0xb/0x10 [<ffffffff812fee27>] device_del+0x157/0x1b0 [<ffffffff8130377d>] platform_device_del+0x1d/0x90 [<ffffffff81303b76>] platform_device_unregister+0x16/0x30 [<ffffffffa030fffd>] regulatory_exit+0x5d/0x180 [cfg80211] [<ffffffffa032bec3>] cfg80211_exit+0x2b/0x45 [cfg80211] [<ffffffff8109a84c>] sys_delete_module+0x16c/0x220 [<ffffffff8108a23e>] ? trace_hardirqs_on_caller+0x7e/0x120 [<ffffffff814cba02>] system_call_fastpath+0x16/0x1b Code: <all your base are belong to me> RIP [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] RSP <ffff88001c5f9d58> CR2: ffff88001a06b5ab ---[ end trace 147c5099a411e8c0 ]--- Reported-by: Johannes Berg <johannes@sipsolutions.net> Cc: Scott James Remnant <keybuk@google.com> Cc: stable@vger.kernel.org Signed-off-by: Luis R.

During link setup, allow special TDLS setup frames through the AP, but otherwise drop all packets destined to the peer. This is required by the TDLS (802.11z) specification in order to prevent reordering of MSDUs between the AP and direct paths.

A TDLS peer is first added just before link setup is initiated. In later setup stages we have more info about peer supported rates, capabilities, etc. This info is reported via nl80211_set_station().

* cfg80211/mac80211: apply station uAPSD parameters selectivelyJohannes Berg2011-09-301-0/+2
| | | | | | | | | | | | Currently, when hostapd sets the station as authorized we also overwrite its uAPSD parameter. This obviously leads to buggy behaviour (later, with my patches that actually add uAPSD support). To fix this, only apply those parameters if they were actually set in nl80211, and to achieve that add a bitmap of things to apply.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Incorrect variable was used in validating the akm_suites array from NL80211_ATTR_AKM_SUITES. In addition, there was no explicit validation of the array length (we only have room for NL80211_MAX_NR_AKM_SUITES). This can result in a buffer write overflow for stack variables with arbitrary data from user space. The nl80211 commands using the affected functionality require GENL_ADMIN_PERM, so this is only exposed to admin users.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new nl80211 attribute to specify whether to send the management frames in CCK rate or not. As of now the wpa_supplicant is disabling CCK rate at P2P init itself. So this patch helps to send P2P probe request/probe response/action frames being sent at non CCK rate in 2GHz without disabling 11b rates. This attribute is used with NL80211_CMD_TRIGGER_SCAN and NL80211_CMD_FRAME commands to disable CCK rate for management frame transmission.

| | | | | | | | | | | | | | | | | | | | Instead of using a hardcoded list of cipher suites in nl80211.c, use a shared function in util.c to verify that the driver advertises support for the specified cipher.

* | cfg80211: Remove strict validation of AKM suitesJouni Malinen2011-09-271-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NL80211_ATTR_AKM_SUITES can be used to configure new AKMs, like FT or the SHA-256 -based AKMs or FT from 802.11r/802.11w. In addition, vendor specific AKMs could be used. The current validation code for the connect command prevents cfg80211-based drivers from using these mechanisms even if the driver would not actually use this AKM value (i.e., it uses WPA/RSN IE from user space). mac80211-based drivers allow any AKM to be used since this value is not used there. Remove the unnecessary validation step in cfg80211 to allow drivers to decide what AKMs are supported. In theory, we could handle this by advertising supported AKMs, but that would not be very effective unless we enforce all drivers (including mac80211) to advertise the set of supported AKMs. This would require additional changes in many places whenever a new AKM is introduced even though no actually functionality changes may be required in most drivers.

The impact is that after a STA disconnects *or* when for any reason a regulatory domain change happens the beacon hint flag is not cleared therefore preventing future beacon hints to be learned. This is important as a regulatory domain change or a restore of regulatory settings would set back the passive scan and no-ibss flags on the channel.

* | cfg80211: hold reg_mutex when updating regulatorySven Neumann2011-09-144-5/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function wiphy_update_regulatory() uses the static variable last_request and thus needs to be called with reg_mutex held. This is the case for all users in reg.c, but the function was exported for use by wiphy_register(), from where it is called without the lock being held. Fix this by making wiphy_update_regulatory() private and introducing regulatory_update() as a wrapper that acquires and holds the lock.

* | nl80211/cfg80211: add match filtering for sched_scanLuciano Coelho2011-09-131-1/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce filtering for scheduled scans to reduce the number of unnecessary results (which cause useless wake-ups). Add a new nested attribute where sets of parameters to be matched can be passed when starting a scheduled scan. Only scan results that match any of the sets will be returned. At this point, the set consists of a single parameter, an SSID. This can be easily extended in the future to support more complex matches.

* | cfg80211/nl80211: Indicate roaming feature capability to userspace.Vivek Natarajan2011-09-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the rssi of the current AP drops, both wpa_supplicant and the firmware may do a background scan to find a better AP and try to associate. Since firmware based roaming is faster, inform wpa_supplicant to avoid roaming and let the firmware decide to roam if necessary. For fullmac drivers like ath6kl, it is just enough to provide the ESSID and the firmware will decide on the BSSID. Since it is not possible to do pre-auth during roaming for fullmac drivers, the wpa_supplicant needs to completely disconnect with the old AP and reconnect with the new AP. This consumes lot of time and it is better to leave the roaming decision to the firmware. Signed-off-by: Vivek Natarajan <nataraja@qca.qualcomm.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the mesh peering frames to the format specified in the recently ratified 802.11s standard. Several changes took place to make this happen: - Change RX path to handle new self-protected frames - Add new Peering management IE - Remove old Peer Link IE - Remove old plink_action field in ieee80211_mgmt header These changes by themselves would either break peering, or work by coincidence, so squash them all into this patch.
