Removing usage of rtnl_lock() to protect firmware interface registers.

The ATM subsystem was incorrectly creating the 'device' link for ATM nodes in sysfs. This led to incorrect device/parent relationships exposed by sysfs and udev.

I noticed that one of the post-2.6.36 patches broke runtime PM of the r8169 on my MSI Wind test machine in such a way that the link was not brought up after reconnecting the network cable. In the process of debugging the issue I realized that we only should invoke the runtime PM functions in rtl8169_check_link_status() when link change is reported and if we do so, the problem goes away. Moreover, this allows rtl8169_runtime_idle() to be simplified quite a bit. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: David S.

2010-12-09net: Convert netpoll blocking api in bonding driver to be a counterNeil Horman
A while back I made some changes to enable netpoll in the bonding driver. Among them was a per-cpu flag that indicated we were in a path that held locks which could cause the netpoll path to block in during tx, and as such the tx path should queue the frame for later use. This appears to have given rise to a regression. If one of those paths on which we hold the per-cpu flag yields the cpu, its possible for us to come back on a different cpu, leading to us clearing a different flag than we set. This results in odd netpoll drops, and BUG backtraces appearing in the log, as we check to make sure that we only clear set bits, and only set clear bits. I had though briefly about changing the offending paths so that they wouldn't sleep, but looking at my origional work more closely, it doesn't appear that a per-cpu flag is warranted. We alrady gate the checking of this flag on IFF_IN_NETPOLL, so we don't hit this in the normal tx case anyway. And practically speaking, the normal use case for netpoll is to only have one client anyway, so we're not going to erroneously queue netpoll frames when its actually safe to do so. As such, lets just convert that per-cpu flag to an atomic counter. It fixes the rescheduling bugs, is equivalent from a performance perspective and actually eliminates some code in the process.

2010-12-08orinoco: fix TKIP countermeasure behaviourDavid Kilroy
Enable the port when disabling countermeasures, and disable it on enabling countermeasures. This bug causes the response of the system to certain attacks to be ineffective. It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning. wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port. The log tends to look like: State: DISCONNECTED -> SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.

To avoid copying the skb unnecessarily move the skb_copy call below the checks that don't need write access to the skb. Also, move the assignment of nh_pos and h_pos below the skb_copy to point to the correct skb. It would be possible to avoid another resize of the copied skb by using skb_copy_expand instead of skb_copy but that would make the patch more complex. Also, shared skbs are a corner case right now, so the resize shouldn't matter much.

Note: this patch should be sent to stable teams (2.6.34 and up) [PATCH net-2.6] llc: fix a device refcount imbalance commit abf9d537fea225 (llc: add support for SO_BINDTODEVICE) added one refcount imbalance in llc_ui_bind(), because dev_getbyhwaddr() doesnt take a reference on device, while dev_get_by_index() does. Fix this using RCU locking. And since an RCU conversion will be done for 2.6.38 for dev_getbyhwaddr(), put the rcu_read_lock/unlock exactly at their final place.

2010-12-08ifb: goto resched directly if error happens and dp->tq isn't emptyChangli Gao
If we break the loop when there are still skbs in tq and no skb in rq, the skbs will be left in txq until new skbs are enqueued into rq. In rare cases, no new skb is queued, then these skbs will stay in rq forever. After this patch, if tq isn't empty when we break the loop, we goto resched directly.

2010-12-08tcp: Bug fix in initialization of receive window.Nandita Dukkipati
The bug has to do with boundary checks on the initial receive window. If the initial receive window falls between init_cwnd and the receive window specified by the user, the initial window is incorrectly brought down to init_cwnd. The correct behavior is to allow it to remain unchanged. Signed-off-by: Nandita Dukkipati <nanditad@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Fix the calculation of the inexact hash-based MAC address filter. It's 64 bits but current code is missing a ULL. Results in filtering out some legitimate packets. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-12-07ath9k: fix beacon resource related race conditionRajkumar Manoharan
The beacon tasklet is accesssing the bslot info for beacon generation. Meanwhile the same slot can be freed on interface deletion. Current the remove_interface disables the beacon alert after freeing the slot. This may leads to null pointer access. This patch disables SWBA and kills the beacon tasklet to prevent access to the slot to be freed. After releasing the slot, swba will be enabled again upon the availablity of beaconing interfaces.

2010-12-07ath9k: Fix STA disconnect issue due to received MIC failed bcast framesSenthil Balasubramanian
AR_RxKeyIdxValid will not be set for bcast/mcast frames and so relying this status for MIC failed frames is buggy. Due to this, MIC failure events for broadcast frames are not sent to supplicant resulted in AP disconnecting the STA. Able to pass Wifi Test case 5.2.18 with this fix.

2010-12-07ath9k: fix a DMA related race condition on resetFelix Fietkau
When ath_drain_all_txq fails to stop DMA, it issues a hw reset. This reset happens at a very problematic point in time, when the hardware rx path has not been stopped yet. This could lead to memory corruption, hardware hangs or other issues. To fix these issues, simply remove the reset entirely and check the tx DMA stop status to prevent problems with fast channel changes.

2010-12-07ath9k: fix bug in tx powerMatteo Croce
The ath9k driver subtracts 3 dBm to the txpower as with two radios the signal power is doubled. The resulting value is assigned in an u16 which overflows and makes the card work at full power.
