2011-11-11nl80211: fix compiler warningJohannes Berg1-1/+1
John reported the following warning: net/wireless/nl80211.c: In function ‘nl80211_tx_mgmt’: net/wireless/nl80211.c:5286:8: warning: ‘hdr’ may be used uninitialized in this function Evidently, his version of gcc isn't able to see that when "msg" is initialized, "hdr" must also be. My gcc, 4.6.1, can actually see that and doesn't warn. Simply initialize the variable to NULL. That means if the compiler was ever right we'll crash though so isn't really optimal since it may hide warnings from the compiler when somebody modifies this code in the future.

2011-11-11cfg80211: merge in beacon ies of hidden bss.Dmitry Tarnyagin1-3/+114
The problem with PSM when a hidden SSID was used was originally reported by Juuso Oikarinen. - When generally scanning, the AP is getting a bss entry with a zero SSID. - When associating, a probe-req is sent to the AP with the SSID, and as a result a probe-response is received with the hidden SSID in place. As a consequence, a second bss entry is created for the AP, now with the real SSID. - After association, mac80211 executes ieee80211_recalc_ps(), but does not switch to powersave because the beacon-ies are missing. As result, the STA does not ever enter PSM. The patch merges in beacon ies of hidden bss from beacon to the probe response, creating a consistent set of ies in place. Patch is depended on "cfg80211: fix cmp_ies" made by Johannes. Signed-off-by: Dmitry Tarnyagin <dmitry.tarnyagin@stericsson.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-11-09cfg80211: fix bug on regulatory core exit on access to last_requestLuis R. Rodriguez1-0/+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.

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.

During the association, the regulatory is updated by country IE that reaps the previously found beacons. 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.

2011-09-14cfg80211: hold reg_mutex when updating regulatorySven Neumann4-5/+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.

2011-09-13cfg80211: print bandwidth in chan_reg_rule_print_dbg()Pavel Roskin1-1/+2
Two spaces and the second "KHz" suggest that the code author meant to print the bandwidth but forgot it. The code appears in commit e702d3cf already with two spaces and "KHz" in place of the bandwidth. Signed-off-by: Pavel Roskin <proski@gnu.org> Acked-by: Luis R.

2011-09-13nl80211/cfg80211: add match filtering for sched_scanLuciano Coelho1-1/+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.
