2013-03-27drivers: net: ethernet: cpsw: use netif_wake_queue() while restarting tx queueMugunthan V N
To restart tx queue use netif_wake_queue() intead of netif_start_queue() so that net schedule will restart transmission immediately which will increase network performance while doing huge data transfers.

2013-03-27net: frag, avoid several CPUs grabbing same frag queue during LRU evictor loopJesper Dangaard Brouer
The LRU list is protected by its own lock, since commit 3ef0eb0db4 (net: frag, move LRU list maintenance outside of rwlock), and no-longer by a read_lock. This makes it possible, to remove the inet_frag_queue, which is about to be "evicted", from the LRU list head. This avoids the problem, of several CPUs grabbing the same frag queue. Note, cannot remove the inet_frag_lru_del() call in fq_unlink() called by inet_frag_kill(), because inet_frag_kill() is also used in other situations. Thus, we use list_del_init() to allow this double list_del to work. Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-03-27xen/events: avoid race with raising an event in unmask_evtchn()David Vrabel
In unmask_evtchn(), when the mask bit is cleared after testing for pending and the event becomes pending between the test and clear, then the upcall will not become pending and the event may be lost or delayed. Avoid this by always clearing the mask bit before checking for pending. If a hypercall is needed, remask the event as EVTCHNOP_unmask will only retrigger pending events if they were masked. This fixes a regression introduced in 3.7 by b5e579232d635b79a3da052964cb357ccda8d9ea (xen/events: fix unmask_evtchn for PV on HVM guests) which reordered the clear mask and check pending operations.

2013-03-27xen/acpi-stub: Disable it b/c the acpi_processor_add is no longer called.Konrad Rzeszutek Wilk
With the Xen ACPI stub code (CONFIG_XEN_STUB=y) enabled, the power C and P states are no longer uploaded to the hypervisor. The reason is that the Xen CPU hotplug code: xen-acpi-cpuhotplug.c and the xen-acpi-stub.c register themselves as the "processor" type object. That means the generic processor (processor_driver.c) stops working and it does not call (acpi_processor_add) which populates the per_cpu(processors, pr->id) = pr; structure. The 'pr' is gathered from the acpi_processor_get_info function which does the job of finding the C-states and figuring out PBLK address. The 'processors->pr' is then later used by xen-acpi-processor.c (the one that uploads C and P states to the hypervisor). Since it is NULL, we end skip the gathering of _PSD, _PSS, _PCT, etc and never upload the power management data. The end result is that enabling the CONFIG_XEN_STUB in the build means that xen-acpi-processor is not working anymore. This temporary patch fixes it by marking the XEN_STUB driver as BROKEN until this can be properly fixed. CC: jinsong.liu@intel.com Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

2013-03-27b43: N-PHY: use more bits for offset in RSSI calibrationRafał Miłecki
When calculating "offset" for final RSSI calibration we're using numbers bigger than s8 can hold. We have for example: offset[j] = 232 - poll_results[j]; formula. If poll_results[j] is small enough (it usually is) we treat number's bit as a sign bit. For example 232 - 1 becomes: 0xE8 - 0x1 = 0xE7, which is not 231 but -25. This code was introduced in e0c9a0219a8f542e3946fe972a68aacf8c3f906c and caused stability regression on some cards, for ex. BCM4322.

2013-03-27b43: A fix for DMA transmission sequence errorsIestyn C. Elfick
Intermittently, b43 will report "Out of order TX status report on DMA ring". When this happens, the driver must be reset before communication can resume. The cause of the problem is believed to be an error in the closed-source firmware; however, all versions of the firmware are affected. This change uses the observation that the expected status is always 2 less than the observed value, and supplies a fake status report to skip one header/data pair. Not all devices suffer from this problem, but it can occur several times per second under heavy load. As each occurence kills the unmodified driver, this patch makes if possible for the affected devices to function. The patch logs only the first instance of the reset operation to prevent spamming the logs.

2013-03-27userns: Restrict when proc and sysfs can be mountedEric W. Biederman
Only allow unprivileged mounts of proc and sysfs if they are already mounted when the user namespace is created. proc and sysfs are interesting because they have content that is per namespace, and so fresh mounts are needed when new namespaces are created while at the same time proc and sysfs have content that is shared between every instance. Respect the policy of who may see the shared content of proc and sysfs by only allowing new mounts if there was an existing mount at the time the user namespace was created. In practice there are only two interesting cases: proc and sysfs are mounted at their usual places, proc and sysfs are not mounted at all (some form of mount namespace jail).

2013-03-27ipc: Restrict mounting the mqueue filesystemEric W. Biederman
Only allow mounting the mqueue filesystem if the caller has CAP_SYS_ADMIN rights over the ipc namespace. The principle here is if you create or have capabilities over it you can mount it, otherwise you get to live with what other people have mounted. This information is not particularly sensitive and mqueue essentially only reports which posix messages queues exist. Still when creating a restricted environment for an application to live any extra information may be of use to someone with sufficient creativity. The historical if imperfect way this information has been restricted has been not to allow mounts and restricting this to ipc namespace creators maintains the spirit of the historical restriction.

2013-03-27vfs: Carefully propogate mounts across user namespacesEric W. Biederman

When the CL_UNPRIVILEGED flag is set cause clone_mnt to set MNT_NO_REMOUNT if any of the mnt flags that should never be changed are set. This protects both mount propagation and the initial creation of a less privileged mount namespace.

2013-03-27userns: Don't allow creation if the user is chrootedEric W. Biederman
Guarantee that the policy of which files may be access that is established by setting the root directory will not be violated by user namespaces by verifying that the root directory points to the root of the mount namespace at the time of user namespace creation. Changing the root is a privileged operation, and as a matter of policy it serves to limit unprivileged processes to files below the current root directory. For reasons of simplicity and comprehensibility the privilege to change the root directory is gated solely on the CAP_SYS_CHROOT capability in the user namespace. Therefore when creating a user namespace we must ensure that the policy of which files may be access can not be violated by changing the root directory. Anyone who runs a processes in a chroot and would like to use user namespace can setup the same view of filesystems with a mount namespace instead. With this result that this is not a practical limitation for using user namespaces.

2013-03-27HID: multitouch: fix touchpad buttonsBenjamin Tissoires
Commit "HID: multitouch: use the callback "report" instead..." breaks the buttons of touchpads following the HID multitouch specification. The buttons were emmitted through hid-input, but as now the events are generated only in hid-multitouch, the buttons are not emmitted anymore. The input_event() call is far much simpler than the hid-input one as many of the different tests do not apply to multitouch touchpads.
