2008-07-08net/wireless/nl80211.c: fix endless Netlink callback loop.master-2008-07-08Julius Volz
Although I only tested similar code (I don't use any of this wireless code), the state maintainance between Netlink dump callback invocations seems wrong here and should lead to an endless loop. There are also other examples in the same file which might have the same problem. Perhaps someone can actually test this (or refute my logic). Take the simple example with only one element in the list (which should fit into the message): 1. invocation: Start: idx = 0, start = 0 Loop: condition (++idx < start) => (1 < 0) => false => no continue, fill one entry, exit loop, return skb->len > 0 2. invocation: Start: idx = 0, start = 1 Loop: condition (++idx < start) => (1 < 1) => false => no continue, fill the same entry again, exit loop, return skb->len > 0 3. invocation: Same as 2. invocation, endless invocation of callback. Also, iterations where the filling of an element fails should not be counted as completed, so idx should not be incremented in this case.

2008-07-08rtl8187: Change detection of RTL8187B with USB ID of 8187Larry Finger
Some early versions of RTL8187B devices have a USB ID of 0x8187 rather than the 0x8189 of later models. In addition, it appears that these early units also must be programmed with lower power. Previous patches used the Product ID string to detect this situation, but did not address the low power question. This patch uses the hardware version and sets the power accordingly.

2008-07-08b43legacy: Remove switch statement with 64-bit indexLarry Finger
The gcc 3.4 fork used to compile the MN10300 port emits unwanted __ucmpdi2() calls for switch statements that use a 64bit value.

rt2400 is the only currently available rt2x00 driver which supports reporting of the RX end time for frames.

2008-07-08rfkill: ignore errors from rfkill_toggle_radio in rfkill_add_switchHenrique de Moraes Holschuh
rfkill_add_switch() calls rfkill_toggle_radio() to set the state of a recently registered rfkill class to the current global state [for that rfkill->type]. The rfkill_toggle_radio() call is going to error out if the hardware is RFKILL_STATE_HARD_BLOCKED, and the global state is RFKILL_STATE_UNBLOCKED. That is a quite normal situation which I missed to account for. As things stand, the error return from rfkill_toggle_radio ends up causing rfkill_register to bail out with an error (de-registering the new switch in the process), which is Not Nice. Change rfkill_add_switch() to not return errors because of a failed call to rfkill_toggle_radio(). We can go back to returning errors again (if that's indeed the right thing to do) if we define the exact error codes the rfkill->toggle_radio callbacks are to return in each situation, so that we can ignore the right ones only.

2008-07-08iwlwifi: remove input device and fix rfkill stateAdel Gadllah
This patch fixes the iwlwifi rfkill. It removes the input device from iwl3945, adds support for RFKILL_STATE_HARD_BLOCKED and calls rfkill_force_state() to update the state rather than accessing it directly. The calls to iwl|iwl3945_rfkill_set_hw_state() had to be moved because rfkill_force_state() cannot be called from an atomic context. Tested on iwl3945 and seems to work fine.
