2014-06-25ipv4: fix dst race in sk_dst_get()Eric Dumazet3-16/+18
When IP route cache had been removed in linux-3.6, we broke assumption that dst entries were all freed after rcu grace period. DST_NOCACHE dst were supposed to be freed from dst_release(). But it appears we want to keep such dst around, either in UDP sockets or tunnels. In sk_dst_get() we need to make sure dst refcount is not 0 before incrementing it, or else we might end up freeing a dst twice. DST_NOCACHE set on a dst does not mean this dst can not be attached to a socket or a tunnel. Then, before actual freeing, we need to observe a rcu grace period to make sure all other cpus can catch the fact the dst is no longer usable.

2014-06-25cxgb4: use dev_port to identify portsThadeu Lima de Souza Cascardo1-0/+1
Commit 3f85944fe207d0225ef21a2c0951d4946fc9a95d ("net: Add sysfs file for port number") introduce dev_port to network devices. cxgb4 adapters have multiple ports on the same PCI function, and used dev_id to identify those ports. That use was removed by commit 8c367fcbe6549195d2eb11e62bea233f811aad41 ("cxgb4: Do not set net_device::dev_id to VI index"), since dev_id should be used only when devices share the same MAC address.

2014-06-25xen-netback: bookkeep number of active queues in our own moduleWei Liu3-52/+26
The original code uses netdev->real_num_tx_queues to bookkeep number of queues and invokes netif_set_real_num_tx_queues to set the number of queues. However, netif_set_real_num_tx_queues doesn't allow real_num_tx_queues to be smaller than 1, which means setting the number to 0 will not work and real_num_tx_queues is untouched. This is bogus when xenvif_free is invoked before any number of queues is allocated. That function needs to iterate through all queues to free resources. Using the wrong number of queues results in NULL pointer dereference. So we bookkeep the number of queues in xen-netback to solve this problem. This fixes a regression introduced by multiqueue patchset in 3.16-rc1. There's another bug in original code that the real number of RX queues is never set. In current Xen multiqueue design, the number of TX queues and RX queues are in fact the same. We need to set the numbers of TX and RX queues to the same value. Also remove xenvif_select_queue and leave queue selection to core driver, as suggested by David Miller.

2014-06-25tg3: Change nvram command timeout value to 50msPrashant Sreedharan1-2/+2
Commit 506724c463fcd63477a5e404728a980b71f80bb7 "tg3: Override clock, link aware and link idle mode during NVRAM dump" changed the timeout value for nvram command execution from 100ms to 1ms. But the 1ms timeout value was only sufficient for nvram read operations but not write operations for most of the devices supported by tg3 driver. This patch sets the MAX to 50ms.

2014-06-25mwifiex: fix Tx timeout issueAmitkumar Karwar1-0/+1
https://bugzilla.kernel.org/show_bug.cgi?id=70191 https://bugzilla.kernel.org/show_bug.cgi?id=77581 It is observed that sometimes Tx packet is downloaded without adding driver's txpd header. This results in firmware parsing garbage data as packet length. Sometimes firmware is unable to read the packet if length comes out as invalid. This stops further traffic and timeout occurs. The root cause is uninitialized fields in tx_info(skb->cb) of packet used to get garbage values. In this case if MWIFIEX_BUF_FLAG_REQUEUED_PKT flag is mistakenly set, txpd header was skipped. This patch makes sure that tx_info is correctly initialized to fix the problem.

2014-06-25ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13Takashi Iwai2-1/+62
HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the default high-pass filter in some "safer" range, which results in the very soft tone from the built-in speakers in contrast to Windows. Also, the mute LED control is missing, since 92HD95 codec still has no HP-specific fixups for GPIO setups. This patch adds these missing features: the HPF is adjusted by the vendor-specific verb, and the LED is set up from a DMI string (but with the default polarity = 0 assumption due to the incomplete BIOS on the given machine).

And in cpuset_mems_allowed(), the access to cpuset is under rcu_read_lock, so in __mpol_dup, we can reduce the rcu_read_lock protection region to protect the access to cpuset only in current_cpuset_is_being_rebound(). So that we can avoid this bug. This patch is a temporary solution that just addresses the bug mentioned above, can not fix the long-standing issue about cpuset.mems rebinding on fork(): "When the forker's task_struct is duplicated (which includes ->mems_allowed) and it races with an update to cpuset_being_rebound in update_tasks_nodemask() then the task's mems_allowed doesn't get updated. And the child task's mems_allowed can be wrong if the cpuset's nodemask changes before the child has been added to the cgroup's tasklist."

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing cleanups and fixes from Steven Rostedt: "This includes three patches from Oleg Nesterov. The first is a fix to a race condition that happens between enabling/disabling syscall tracepoints and new process creations (the check to go into the ptrace path for a process can be set when it shouldn't, or not set when it should). Not a major bug but one that should be fixed and even applied to stable. The other two patches are cleanup/fixes that are not that critical, but for an -rc1 release would be nice to have. They both deal with syscall tracepoints. It also includes a patch to introduce a new macro for the TRACE_EVENT() format called __field_struct(). Originally, __field() was used to record any variable into a trace event, but with the addition of setting the "is signed" attribute, the check causes anything but a primitive variable to fail to compile. That is, structs and unions can't be used as they once were. When the "is signed" check was introduce there were only primitive variables being recorded. But that will change soon and it was reported that __field() causes build failures. To solve the __field() issue, __field_struct() is introduced to allow trace_events to be able to record complex types too" * tag 'trace-fixes-v3.16-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Add __field_struct macro for TRACE_EVENT() tracing: syscall_regfunc() should not skip kernel threads tracing: Change syscall_*regfunc() to check PF_KTHREAD and use for_each_process_thread() tracing: Fix syscall_*regfunc() vs copy_process() race
2014-06-25KVM: PPC: BOOK3S: HV: Use base page size when comparing against slb valueAneesh Kumar K.V3-8/+20
With guests supporting Multiple page size per segment (MPSS), hpte_page_size returns the actual page size used. Add a new function to return base page size and use that to compare against the the page size calculated from SLB. Without this patch a hpte lookup can fail since we are comparing wrong page size in kvmppc_hv_find_lock_hpte.

AT91 symbols AT91SAM9263, AT91SAM9RL, and AT91SAM9G45 do not exist and this patch changes them to their correct ARCH_* version. These symbols are chosen instead of the SOC_* ones because this driver is not converted to DT. Anyway, the ATMEL_PWM symbol and the associated driver will be removed soon, during the move to the PWM sub-system.

2014-06-25virtio-scsi: fix various bad behavior on aborted requestsPaolo Bonzini1-0/+22
Even though the virtio-scsi spec guarantees that all requests related to the TMF will have been completed by the time the TMF itself completes, the request queue's callback might not have run yet. This causes requests to be completed more than once, and as a result triggers a variety of BUGs or oopses.
