The sn9c102 driver is deprecated. It was moved to staging in anticipation of its removal in a future kernel version. However, USB devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when both sn9c102 and gspca_sonixb are enabled. We must migrate all the users of these devices to the gspca_sonixb driver now, so that it gets sufficient testing before the sn9c102 driver is finally phased out. Signed-off-by:

this patch makes sure that it terminates if any IO in progress and also makes sure that all the buffers are unmapped. It was observed that with several runs of application the application sometimes failed to allocate memory, This patch makes sure it all the buffers are released. Using kmemleak it was found that buffer were not released, this patch fixes following issue, echo scan > /sys/kernel/debug/kmemleak Kernel message reads: memleak: 3 new suspected memory leaks (see /sys/kernel/debug/kmemleak) Then, cat /sys/kernel/debug/kmemleak unreferenced object 0xc564a480 (size 192): comm "mttest", pid 764, jiffies 4294945878 (age 487.160s) hex dump (first 32 bytes): 00 00 00 00 28 07 07 20 d0 02 00 00 e0 01 00 00 ....(.. ........ 00 00 00 00 00 64 05 00 01 00 00 00 01 00 00 00 .....d.......... backtrace: [<c00a98dc>] create_object+0x10c/0x28c [<c03ba8ec>] kmemleak_alloc+0x3c/0x70 [<c00a67c0>] __kmalloc+0x11c/0x1d4 [<c02b6f48>] __videobuf_alloc+0x1c/0x3c [<c02b6194>] videobuf_alloc_vb+0x38/0x80 [<c02b6638>] __videobuf_mmap_setup+0x9c/0x108 [<c02b6da0>] videobuf_reqbufs.part.10+0x12c/0x1bc [<c02b6e9c>] videobuf_reqbufs+0x6c/0x8c [<c02be2c4>] vpfe_reqbufs+0xcc/0x130 [<c02aae90>] v4l_reqbufs+0x50/0x54 [<c02aab54>] __video_do_ioctl+0x260/0x2c4 [<c02a9dd4>] video_usercopy+0xf0/0x310 [<c02aa008>] video_ioctl2+0x14/0x1c [<c02a562c>] v4l2_ioctl+0x104/0x14c [<c00bd320>] do_vfs_ioctl+0x80/0x2d0 [<c00bd5b4>] SyS_ioctl+0x44/0x64 unreferenced object 0xc564ac00 (size 192): comm "mttest", pid 764, jiffies 4294945878 (age 487.160s) hex dump (first 32 bytes): 01 00 00 00 28 07 07 20 d0 02 00 00 e0 01 00 00 ....(.. ........ 00 00 00 00 00 64 05 00 01 00 00 00 01 00 00 00 .....d.......... backtrace: [<c00a98dc>] create_object+0x10c/0x28c [<c03ba8ec>] kmemleak_alloc+0x3c/0x70 [<c00a67c0>] __kmalloc+0x11c/0x1d4 [<c02b6f48>] __videobuf_alloc+0x1c/0x3c [<c02b6194>] videobuf_alloc_vb+0x38/0x80 [<c02b6638>] __videobuf_mmap_setup+0x9c/0x108 [<c02b6da0>] videobuf_reqbufs.part.10+0x12c/0x1bc [<c02b6e9c>] videobuf_reqbufs+0x6c/0x8c [<c02be2c4>] vpfe_reqbufs+0xcc/0x130 [<c02aae90>] v4l_reqbufs+0x50/0x54 [<c02aab54>] __video_do_ioctl+0x260/0x2c4 [<c02a9dd4>] video_usercopy+0xf0/0x310 [<c02aa008>] video_ioctl2+0x14/0x1c [<c02a562c>] v4l2_ioctl+0x104/0x14c [<c00bd320>] do_vfs_ioctl+0x80/0x2d0 [<c00bd5b4>] SyS_ioctl+0x44/0x64 unreferenced object 0xc564a180 (size 192): comm "mttest", pid 764, jiffies 4294945880 (age 487.140s) hex dump (first 32 bytes): 02 00 00 00 28 07 07 20 d0 02 00 00 e0 01 00 00 ....(.. ........ 00 00 00 00 00 64 05 00 01 00 00 00 01 00 00 00 .....d.......... backtrace: [<c00a98dc>] create_object+0x10c/0x28c [<c03ba8ec>] kmemleak_alloc+0x3c/0x70 [<c00a67c0>] __kmalloc+0x11c/0x1d4 [<c02b6f48>] __videobuf_alloc+0x1c/0x3c [<c02b6194>] videobuf_alloc_vb+0x38/0x80 [<c02b6638>] __videobuf_mmap_setup+0x9c/0x108 [<c02b6da0>] videobuf_reqbufs.part.10+0x12c/0x1bc [<c02b6e9c>] videobuf_reqbufs+0x6c/0x8c [<c02be2c4>] vpfe_reqbufs+0xcc/0x130 [<c02aae90>] v4l_reqbufs+0x50/0x54 [<c02aab54>] __video_do_ioctl+0x260/0x2c4 [<c02a9dd4>] video_usercopy+0xf0/0x310 [<c02aa008>] video_ioctl2+0x14/0x1c [<c02a562c>] v4l2_ioctl+0x104/0x14c [<c00bd320>] do_vfs_ioctl+0x80/0x2d0 [<c00bd5b4>] SyS_ioctl+0x44/0x64 Reported-by:Jimmy Ho <jimmygge@gmail.com> Signed-off-by:

This patch fixes I/O errors with the sym53c8xx_2 driver when the disk returns QUEUE FULL status. When the controller encounters an error (including QUEUE FULL or BUSY status), it aborts all not yet submitted requests in the function sym_dequeue_from_squeue. This function aborts them with DID_SOFT_ERROR. If the disk has full tag queue, the request that caused the overflow is aborted with QUEUE FULL status (and the scsi midlayer properly retries it until it is accepted by the disk), but the sym53c8xx_2 driver aborts the following requests with DID_SOFT_ERROR --- for them, the midlayer does just a few retries and then signals the error up to sd. The result is that disk returning QUEUE FULL causes request failures. The error was reproduced on 53c895 with COMPAQ BD03685A24 disk (rebranded ST336607LC) with command queue 48 or 64 tags. The disk has 64 tags, but under some access patterns it return QUEUE FULL when there are less than 64 pending tags. The SCSI specification allows returning QUEUE FULL anytime and it is up to the host to retry. Signed-off-by:

Commit 8f619b54 ("powerpc/ppc64: Do not turn AIL (reloc-on interrupts) too early") added code to set the AIL bit in the LPCR without checking whether the kernel is running in hypervisor mode. The result is that when the kernel is running as a guest (i.e., under PowerKVM or PowerVM), the processor takes a privileged instruction interrupt at that point, causing a panic. The visible result is that the kernel hangs after printing "returning from prom_init". This fixes it by checking for hypervisor mode being available before setting LPCR. If we are not in hypervisor mode, we enable relocation-on interrupts later in pSeries_setup_arch using the H_SET_MODE hcall. Signed-off-by:

One was a late fix and the other a consequence of overlooking the whole requeuing logic. The first change caused our documentation to be incorrect, and the second made us aware that we need to explicitly add more details to it. Signed-off-by:

Pull yet more networking updates from David Miller: 1) Various fixes to the new Redpine Signals wireless driver, from Fariya Fatima. 2) L2TP PPP connect code takes PMTU from the wrong socket, fix from Dmitry Petukhov. 3) UFO and TSO packets differ in whether they include the protocol header in gso_size, account for that in skb_gso_transport_seglen(). From Florian Westphal. 4) If VLAN untagging fails, we double free the SKB in the bridging output path. From Toshiaki Makita. 5) Several call sites of sk->sk_data_ready() were referencing an SKB just added to the socket receive queue in order to calculate the second argument via skb->len. This is dangerous because the moment the skb is added to the receive queue it can be consumed in another context and freed up. It turns out also that none of the sk->sk_data_ready() implementations even care about this second argument. So just kill it off and thus fix all these use-after-free bugs as a side effect. 6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti. 7) pktgen needs to do locking properly for LLTX devices, from Daniel Borkmann. 8) xen-netfront driver initializes TX array entries in RX loop :-) From Vincenzo Maffione. 9) After refactoring, some tunnel drivers allow a tunnel to be configured on top itself.

Nicolas Dichtel says: ==================== tunnels: don't allow to add the same tunnel twice This series fixes the check of an existing tunnel with the same parameters when a new tunnel is added. I've checked all users of ip_tunnel_newlink(): gre, gretap, ipip and vti. The bug exists only for gre and vti. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Before the patch, it was possible to add two times the same tunnel: ip l a vti1 type vti remote 10.16.0.121 local 10.16.0.249 key 41 ip l a vti2 type vti remote 10.16.0.121 local 10.16.0.249 key 41 It was possible, because ip_tunnel_newlink() calls ip_tunnel_find() with the argument dev->type, which was set only later (when calling ndo_init handler in register_netdevice()). Let's set this type in the setup handler, which is called before newlink handler. Introduced by commit b9959fd3 ("vti: switch to new ip tunnel code").

This patch fixes the initialization of an array used in the TX datapath that was mistakenly initialized together with the RX datapath arrays. An out of range array access could happen when RX and TX rings had different sizes. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000, e1000e, igb, igbvf, ixgb, ixgbe, ixgbevf and i40evf. Mark fixes an issue with ixgbe and ixgbevf by adding a bit to indicate when workqueues have been initialized. This permits the register read error handling from attempting to use them prior to that, which also generates warnings. Checking for a detected removal after initializing the work queues allows the probe function to return an error without getting the workqueue involved. Further, if the error_detected callback is entered before the workqueues are initialized, exit without recovery since the device initialization was so truncated. Francois Romieu provides several patches to all the drivers to remove the open coded skb_cow_head. Jakub Kicinski provides a fix for igb where last_rx_timestamp should be updated only when Rx time stamp is read. Mitch provides a fix for i40evf where a recent change broke the RSS LUT programming causing it to be programmed with all 0's. ==================== Signed-off-by: -

Pull more tracing updates from Steven Rostedt: "This includes the final patch to clean up and fix the issue with the design of tracepoints and how a user could register a tracepoint and have that tracepoint not be activated but no error was shown. The design was for an out of tree module but broke in tree users. The clean up was to remove the saving of the hash table of tracepoint names such that they can be enabled before they exist (enabling a module tracepoint before that module is loaded). This added more complexity than needed. The clean up was to remove that code and just enable tracepoints that exist or fail if they do not. This removed a lot of code as well as the complexity that it brought. As a side effect, instead of registering a tracepoint by its name, the tracepoint needs to be registered with the tracepoint descriptor. This removes having to duplicate the tracepoint names that are enabled. The second patch was added that simplified the way modules were searched for. This cleanup required changes that were in the 3.15 queue as well as some changes that were added late in the 3.14-rc cycle. This final change waited till the two were merged in upstream and then the change was added and full tests were run. Unfortunately, the test found some errors, but after it was already submitted to the for-next branch and not to be rebased. Sparse errors were detected by Fengguang Wu's bot tests, and my internal tests discovered that the anonymous union initialization triggered a bug in older gcc compilers. Luckily, there was a bugzilla for the gcc bug which gave a work around to the problem. The third and fourth patch handled the sparse error and the gcc bug respectively. A final patch was tagged along to fix a missing documentation for the README file" * tag 'trace-3.15-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Add missing function triggers dump and cpudump to README tracing: Fix anonymous unions in struct ftrace_event_call tracepoint: Fix sparse warnings in tracepoint.c tracepoint: Simplify tracepoint module search tracepoint: Use struct pointer instead of name hash for reg/unreg tracepoints

O_APPEND handling there hadn't been completely fixed by Pavel's patch; it checks the right value, but it's racy - we can't really do that until i_mutex has been taken. Fix by switching to __generic_file_aio_write() (open-coding generic_file_aio_write(), actually) and pulling mutex_lock() above inode_size_read(). Cc: stable@vger.kernel.org Signed-off-by: -

Similarly to commit 43279500 ("packet: respect devices with LLTX flag in direct xmit"), we can basically apply the very same to pktgen. This will help testing against LLTX devices such as dummy driver (or others), which only have a single netdevice txq and would otherwise require locking their txq from pktgen side while e.g. in dummy case, we would not need any locking. Fix this by making use of HARD_TX_{UN,}LOCK API, so that NETIF_F_LLTX will be respected. Signed-off-by:
