2013-08-13ethernet/arc/arc_emac - fix NAPI "work > weight" warningAlexey Brodkin
Initially I improperly set a boundary for maximum number of input packets to process on NAPI poll ("work") so it might be more than expected amount ("weight"). This was really harmless but seeing WARN_ON_ONCE on every device boot is not nice. So trivial fix ("<" instead of "<=") is here.

2013-08-13ip_tunnel: Do not use inner ip-header-id for tunnel ip-header-id.Pravin B Shelar
Using inner-id for tunnel id is not safe in some rare cases. E.g. packets coming from multiple sources entering same tunnel can have same id. Therefore on tunnel packet receive we could have packets from two different stream but with same source and dst IP with same ip-id which could confuse ip packet reassembly. Following patch reverts optimization from commit 490ab08127 (IP_GRE: Fix IP-Identification.)

2013-08-13tcp: reset reordering est. selectively on timeoutYuchung Cheng
On timeout the TCP sender unconditionally resets the estimated degree of network reordering (tp->reordering). The idea behind this is that the estimate is too large to trigger fast recovery (e.g., due to a IP path change). But for example if the sender only had 2 packets outstanding, then a timeout doesn't tell much about reordering. A sender that learns about reordering on big writes and loses packets on small writes will end up falsely retransmitting again and again, especially when reordering is more likely on big writes. Therefore the sender should only suspect that tp->reordering is too high if it could have gone into fast recovery with the (lower) default estimate.

2013-08-14PM / QoS: Fix workqueue deadlock when using pm_qos_update_request_timeout()Stephen Boyd
pm_qos_update_request_timeout() updates a qos and then schedules a delayed work item to bring the qos back down to the default after the timeout. When the work item runs, pm_qos_work_fn() will call pm_qos_update_request() and deadlock because it tries to cancel itself via cancel_delayed_work_sync(). Future callers of that qos will also hang waiting to cancel the work that is canceling itself. Let's extract the little bit of code that does the real work of pm_qos_update_request() and call it from the work function so that we don't deadlock. Before ed1ac6e (PM: don't use [delayed_]work_pending()) this didn't happen because the work function wouldn't try to cancel itself.

2013-08-13gianfar: Add flow control supportClaudiu Manoil
eTSEC has Rx and Tx flow control capabilities that may be enabled through MACCFG1[Rx_Flow, Tx_Flow] bits. These bits must not be set however when eTSEC is operated in Half-Duplex mode. Unfortunately, the driver currently sets these bits unconditionally. This patch adds the proper handling of the PAUSE frame capability register bits by implementing the ethtool -A interface. When pause autoneg is enabled, the controller uses the phy's capability to negotiate PAUSE frame settings with the link partner and reconfigures its Rx_Flow and Tx_Flow settings to match the capabilities of the link partner. If pause autoneg is off, the PAUSE frame generation may be forced manually (ethtool -A). Flow control is disabled by default now. This implementation is inspired by the tg3 driver.

2013-08-13sched: fix the theoretical signal_wake_up() vs schedule() raceOleg Nesterov
This is only theoretical, but after try_to_wake_up(p) was changed to check p->state under p->pi_lock the code like __set_current_state(TASK_INTERRUPTIBLE); schedule(); can miss a signal. This is the special case of wait-for-condition, it relies on try_to_wake_up/schedule interaction and thus it does not need mb() between __set_current_state() and if(signal_pending). However, this __set_current_state() can move into the critical section protected by rq->lock, now that try_to_wake_up() takes another lock we need to ensure that it can't be reordered with "if (signal_pending(current))" check inside that section. The patch is actually one-liner, it simply adds smp_wmb() before spin_lock_irq(rq->lock). This is what try_to_wake_up() already does by the same reason. We turn this wmb() into the new helper, smp_mb__before_spinlock(), for better documentation and to allow the architectures to change the default implementation. While at it, kill smp_mb__after_lock(), it has no callers. Perhaps we can also add smp_mb__before/after_spinunlock() for prepare_to_wait().

2013-08-13genetlink: fix family dump raceJohannes Berg
When dumping generic netlink families, only the first dump call is locked with genl_lock(), which protects the list of families, and thus subsequent calls can access the data without locking, racing against family addition/removal. This can cause a crash. Fix it - the locking needs to be conditional because the first time around it's already locked. A similar bug was reported to me on an old kernel (3.4.47) but the exact scenario that happened there is no longer possible, on those kernels the first round wasn't locked either. Looking at the current code I found the race described above, which had also existed on the old kernel.

Probably this one is quite unlikely to be triggered, but it's more safe to do the call_rcu() at the end after we have dropped the reference on the asoc and freed sctp packet chunks. The reason why is because in sctp_transport_destroy_rcu() the transport is being kfree()'d, and if we're unlucky enough we could run into corrupted pointers. Probably that's more of theoretical nature, but it's safer to have this simple fix. Introduced by commit 8c98653f ("sctp: sctp_close: fix release of bindings for deferred call_rcu's").

Fix endianess bugs in firmware handling introduced by commits cb7a7c6a ("ti_usb_3410_5052: add Multi-Tech modem support") and 05a3d905 ("ti_usb_3410_5052: support alternate firmware") which made the driver use the wrong firmware for certain devices on big-endian machines.

2013-08-12USB-Serial: Fix error handling of usb_wwanMatt Burtch
This fixes an issue where the bulk-in urb used for incoming data transfer is not resubmitted if the packet recieved contains an error status. This results in the driver locking until the port is closed and re-opened. Tested on a custom board with a Cinterion GSM module.

2013-08-12wusbcore: fix kernel panic when disconnecting a wireless USB->serial deviceThomas Pugliese
This patch fixes a kernel panic that can occur when disconnecting a wireless USB->serial device. When the serial device disconnects, the device cleanup procedure ends up calling usb_hcd_disable_endpoint on the serial device's endpoints. The wusbcore uses the ABORT_RPIPE command to abort all transfers on the given endpoint but it does not properly give back the URBs when the transfer results return from the HWA. This patch prevents the transfer result processing code from bailing out when it sees a WA_XFER_STATUS_ABORTED result code so that these urbs are flushed properly by usb_hcd_disable_endpoint. It also updates wa_urb_dequeue to handle the case where the endpoint has already been cleaned up when usb_kill_urb is called which is where the panic originally occurred.

2013-08-12USB: EHCI: accept very late isochronous URBsAlan Stern
Since commits 4005ad4390bf (EHCI: implement new semantics for URB_ISO_ASAP) and c75c5ab575af (ALSA: USB: adjust for changed 3.8 USB API) became widely distributed, people have been experiencing problems with audio transfers. The slightest underrun causes complete failure, requiring the audio stream to be restarted. It turns out that the current isochronous API doesn't handle underruns in the best way. The ALSA developers would much rather have transfers that are submitted too late be accepted and complete in the normal fashion, rather than being refused outright. This patch implements the requested approach. When an isochronous URB submission is so late that all its scheduled slots have already expired, a debugging message will be printed in the log and the URB will be accepted as usual. Assuming it was submitted by a completion handler (which is normally the case), it will complete shortly thereafter with all the usb_iso_packet_descriptor status fields marked -EXDEV. This fixes (for ehci-hcd) https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1191603 It should be applied to all kernels that include commit 4005ad4390bf.

2013-08-12ALSA: hda - Fix missing mute controls for CX5051Takashi Iwai
We've added a fake mute control (setting the amp volume to zero) for CX5051 at commit [3868137e: ALSA: hda - Add a fake mute feature], but this feature was overlooked in the generic parser implementation. Now the driver lacks of mute controls on these codecs. The fix is just to check both AC_AMPCAP_MUTE and AC_AMPCAP_MIN_MUTE bits in each place checking the amp capabilities.
