* rtl8187: ->brightness_set can not sleepStanislaw Gruszka2012-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 0fde0a8cfd0ede7f310d6a681c8e5a7cb3e32406 upstream. Fix: BUG: sleeping function called from invalid context at kernel/workqueue.c:2547 in_atomic(): 1, irqs_disabled(): 0, pid: 629, name: wpa_supplicant 2 locks held by wpa_supplicant/629: #0: (rtnl_mutex){+.+.+.}, at: [<c08b2b84>] rtnl_lock+0x14/0x20 #1: (&trigger->leddev_list_lock){.+.?..}, at: [<c0867f41>] led_trigger_event+0x21/0x80 Pid: 629, comm: wpa_supplicant Not tainted 3.3.0-0.rc3.git5.1.fc17.i686 Call Trace: [<c046a9f6>] __might_sleep+0x126/0x1d0 [<c0457d6c>] wait_on_work+0x2c/0x1d0 [<c045a09a>] __cancel_work_timer+0x6a/0x120 [<c045a160>] cancel_delayed_work_sync+0x10/0x20 [<f7dd3c22>] rtl8187_led_brightness_set+0x82/0xf0 [rtl8187] [<c0867f7c>] led_trigger_event+0x5c/0x80 [<f7ff5e6d>] ieee80211_led_radio+0x1d/0x40 [mac80211] [<f7ff3583>] ieee80211_stop_device+0x13/0x230 [mac80211] Removing _sync is ok, because if led_on work is currently running it will be finished before led_off work start to perform, since they are always queued on the same mac80211 local->workqueue.

* rtl8187: Change rate-control feedbackLarry Finger2011-03-04
| | | | | | | | | | | | | | The driver for the RTL8187L chips returns IEEE80211_TX_STAT_ACK for all packets, even if the maximum number of retries was exhausted. In addition it fails to setup max_rates in the ieee80211_hw struct, This behavior may be responsible for the problems noted in Bug 14168. As the bug is very old, testers have not been found, and I do not have the case where the indicated signal is less than -70 dBm.

* mac80211: make tx() operation return voidJohannes Berg2011-02-25
| | | | | | | | | | | | | | | | | | | | | | The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

* mac80211: rename RX_FLAG_TSFTJohannes Berg2011-02-23
| | | | | | | | | | The flag isn't very descriptive -- the intention is that the driver provides a TSF timestamp at the beginning of the MPDU -- make that clearer by renaming the flag to RX_FLAG_MACTIME_MPDU.

* rtl818x: move rtl8180 and rtl8187 to separate subdirectoriesJohn W. Linville2010-12-22
These drivers share one header file, but nothing else. Worse, both drivers use the rtl8225 part with different register settings. The results has been some ugly naming -- let's simplify that.
