commit a535d81c upstream. The dwc3 UDC driver doesn't implement endpoint wedging correctly. When an endpoint is wedged, the gadget driver should be allowed to clear the wedge by calling usb_ep_clear_halt(). Only the host is prevented from resetting the endpoint. This patch fixes the implementation. Signed-off-by:

commit 2d51f3cd upstream. This patch adds a check for USB_STATE_NOTATTACHED to the hub_port_warm_reset_required() workaround for ports that end up in Compliance Mode in hub_events() when trying to decide which reset function to use. Trying to call usb_reset_device() with a NOTATTACHED device will just fail and leave the port broken. Signed-off-by:

commit f12d5bfc upstream. The hugepage code had the exact same bug that regular pages had in commit 7485d0d3 ("futexes: Remove rw parameter from get_futex_key()"). The regular page case was fixed by commit 9ea71503 ("futex: Fix regression with read only mappings"), but the transparent hugepage case (added in a5b338f2: "thp: update futex compound knowledge") case remained broken. Found by Dave Jones and his trinity tool. Reported-and-tested-by:

commit 338c7dba upstream. In multiple functions the vcpu_id is used as an offset into a bitfield. Ag malicious user could specify a vcpu_id greater than 255 in order to set or clear bits in kernel memory. This could be used to elevate priveges in the kernel. This patch verifies that the vcpu_id provided is less than 255. The api documentation already specifies that the vcpu_id must be less than max_vcpus, but this is currently not checked. Reported-by:

commit 1b15ec7a upstream. get_wchan() is lockless. Task may wakeup at any time and change its own stack, thus each next stack frame may be overwritten and filled with random stuff. /proc/$pid/stack interface had been disabled for non-current tasks, see [1] But 'wchan' still allows to trigger stack frame unwinding on volatile stack. This patch fixes oops in unwind_frame() by adding stack pointer validation on each step (as x86 code do), unwind_frame() already checks frame pointer. Also I've found another report of this oops on stackoverflow (irony).

commit 7f4d3641 upstream. Unlike what the comment states, errata i660 does not state that we can't RESET the USB host module. Instead it states that RESET is the only way to recover from a deadlock situation. RESET ensures that the module is in a known good state irrespective of what bootloader does with the module, so it must be done at boot. Signed-off-by:

commit 932e9dec upstream. When running a 32bit kernel the hda_intel driver is still reporting a 64bit dma_mask if the HW supports it. From sound/pci/hda/hda_intel.c: /* allow 64bit DMA address if supported by H/W */ if ((gcap & ICH6_GCAP_64OK) && !pci_set_dma_mask(pci, DMA_BIT_MASK(64))) pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(64)); else { pci_set_dma_mask(pci, DMA_BIT_MASK(32)); pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(32)); } which means when there is a call to dma_alloc_coherent from snd_malloc_dev_pages a machine address bigger than 32bit can be returned. This can be true in particular if running the 32bit kernel as a pv dom0 under the Xen Hypervisor or PAE on bare metal. The problem is that when calling setup_bdle to program the BLE the dma_addr_t returned from the dma_alloc_coherent is wrongly truncated from snd_sgbuf_get_addr if running a 32bit kernel: static inline dma_addr_t snd_sgbuf_get_addr(struct snd_dma_buffer *dmab, size_t offset) { struct snd_sg_buf *sgbuf = dmab->private_data; dma_addr_t addr = sgbuf->table[offset >> PAGE_SHIFT].addr; addr &= PAGE_MASK; return addr + offset % PAGE_SIZE; } where PAGE_MASK in a 32bit kernel is zeroing the upper 32bit af addr. Without this patch the HW will fetch the 32bit truncated address, which is not the one obtained from dma_alloc_coherent and will result to a non working audio but can corrupt host memory at a random location. The current patch apply to v3.13-rc3-74-g6c843f5 Signed-off-by:

commit f86f55d3 upstream. The BMIPS5000 (Zephyr) processor utilizes instruction speculation. A stale misprediction address in either the JTB or the CRS may trigger a prefetch inside a region that is currently being used by a DMA engine, which is not IO-coherent. This prefetch will fetch a line into the scache, and that line will soon become stale (ie wrong) during/after the DMA. Mayhem ensues. In dma-default.c, the r10000 is handled as a special case in the same way that we want to handle Zephyr. So we generalize the exception cases into a function, and include Zephyr as one of the processors that needs this special care. Signed-off-by:

commit a3132499 upstream. This patch fixes the CS5 setting on the PL2303 USB-to-serial devices. CS5 has a value of 0 and the CSIZE setting has been skipped altogether by the enclosing if. Tested on 3.11.6 and the scope shows the correct output after the fix has been applied. Tagged to be added to stable, because it fixes a user visible driver bug and is simple enough to backport easily. Signed-off-by:

commit bcd26230 upstream. There is plenty of consumer hardware (e.g., mac books) that does not use AT keyboards or PS/2 mice. It therefore makes sense for distro kernels to build the related drivers as modules to avoid loading them on hardware that does not need them. As such, these options should no longer be protected by EXPERT. Moreover, building these drivers as modules gets rid of the following ugly error during boot: [ 2.337745] i8042: PNP: No PS/2 controller found. Probing ports directly.

commit ac01810c upstream. When the system enters suspend, it disables all interrupts in suspend_device_irqs(), including the interrupts marked EARLY_RESUME. On the resume side things are different. The EARLY_RESUME interrupts are reenabled in sys_core_ops->resume and the non EARLY_RESUME interrupts are reenabled in the normal system resume path. When suspend_noirq() failed or suspend is aborted for any other reason, we might omit the resume side call to sys_core_ops->resume() and therefor the interrupts marked EARLY_RESUME are not reenabled and stay disabled forever. To solve this, enable all irqs unconditionally in irq_resume() regardless whether interrupts marked EARLY_RESUMEhave been already enabled or not. This might try to reenable already enabled interrupts in the non failure case, but the only affected platform is XEN and it has been confirmed that it does not cause any side effects.

commit 1aeef303 upstream. For MPC8572/MPC8536, the status of GPIOs defined as output cannot be determined by reading GPDAT register, so the code use shadow data register instead. But the code may give the wrong status of GPIOs defined as input under some scenarios: 1. If some pins were configured as inputs and were asserted high before booting the kernel, the shadow data has been initialized with those pin values. 2. Some pins have been configured as output first and have been set to the high value, then reconfigured as input. The above cases will make the shadow data for those input pins to be set to high. Then reading the pin status will always return high even if the actual pin status is low. The code should eliminate the effects of the shadow data to the input pins, and the status of those pins should be read directly from GPDAT. Acked-by:

commit 88bf6d62 upstream. A return value of 1 is interpreted as an error. See pci_driver. in local_pci_probe(). If you're wondering how this ever could have worked, it's because it used to be the case that only return values less than zero were interpreted as failure. But even in the current kernel if the driver registers its various entry points with the kernel, and then returns a value which is interpreted as failure, those registrations aren't undone, so the driver still mostly works. However, the driver's remove function wouldn't be called on rmmod, and pci power management functions wouldn't work. In the case of Smart Array, since it has a battery backed cache (or else no cache) even if the driver is not shut down properly as long as there is no outstanding i/o, nothing too bad happens, which is why it took so long to notice. Requesting backport to stable because the change to pci-driver.c which requires driver probe functions to return 0 occurred between 2.6.35 and 2.6.36 (the pci power management breakage) and again between 3.7 and 3.8 (pci_dev->driver getting set to NULL in local_pci_probe() preventing driver remove function from being called on rmmod.)

commit 2e311fba upstream. We inadvertantly discarded the scsi status for aborted commands. For some commands (e.g. reads from tape drives) these can't be retried, and if we discarded the scsi status, the scsi mid layer couldn't notice anything was wrong and the error was not reported.

commit ae5fbae0 upstream. Since commit 110dd8f1 "[SCSI] libsas: fix scr_read/write users and update the libata documentation" we have been passing pmp=1 and is_cmd=0 to ata_tf_to_fis(). Praveen reports that eSATA attached drives do not discover correctly. His investigation found that the BIOS was passing pmp=0 while Linux was passing pmp=1 and failing to discover the drives. Update libsas to follow the libata example of pulling the pmp setting from the ata_link and correct is_cmd to be 1 since all tf's submitted through ->qc_issue are commands. Presumably libsas lldds do not care about is_cmd as they have sideband mechanisms to perform link management. http://marc.info/?l=linux-scsi&m=138179681726990 [jejb: checkpatch fix] Signed-off-by:

commit a1470c7b upstream. Bug report from: wenxiong@linux.vnet.ibm.com The issue is happened in dual controller configuration. We got the sysfs warnings when rmmod the ipr module. enclosure_unregister() in drivers/msic/enclosure.c, call device_unregister() for each componment deivce, device_unregister() ->device_del()->kobject_del() ->sysfs_remove_dir(). In sysfs_remove_dir(), set kobj->sd = NULL. For each componment device, enclosure_component_release()->enclosure_remove_links()->sysfs_remove_link() in which checking kobj->sd again, it has been set as NULL when doing device_unregister. So we saw all these sysfs WARNING. Tested-by: wenxiong@linux.vnet.ibm.com Signed-off-by:

commit b4af6ef9 upstream. According to WM8731 "PD, Rev 4.9 October 2012" datasheet, when it works in DSP mode A, LRP = 1, while works in DSP mode B, LRP = 0. So, fix LRP for DSP mode as the datesheet specification. Signed-off-by:

commit fc019c71 upstream. When performing an asynchronous ablkcipher operation the authenc completion callback routine is invoked, but it does not locate and use the proper IV. The callback routine, crypto_authenc_encrypt_done, is updated to use the same method of calculating the address of the IV as is done in crypto_authenc_encrypt function which sets up the callback.

commit 5638cabf upstream. There are cases when cryptlen can be zero in crypto_ccm_auth(): -encryptiom: input scatterlist length is zero (no plaintext) -decryption: input scatterlist contains only the mac plus the condition of having different source and destination buffers (or else scatterlist length = max(plaintext_len, ciphertext_len)). These are not handled correctly, leading to crashes like: root@p4080ds:~/crypto# insmod tcrypt.ko mode=45 ------------[ cut here ]------------ kernel BUG at crypto/scatterwalk.c:37!

commit 41da8b5a upstream. The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain function to chain two scatterlists, but the chain pointer indication bit is not set. When the resulting scatterlist is used, for example, by sg_nents to count the number of scatterlist entries, a segfault occurs because sg_nents does not follow the chain pointer to the chained scatterlist. Update scatterwalk_sg_chain to set the chain pointer indication bit as is done by the sg_chain function. Signed-off-by:
