commit 313a76ee upstream. In _ocp_softreset(), after _set_softreset() + write_sysconfig(), the hwmod's sysc_cache will always contain SOFTRESET bit set so all further writes to sysconfig using this cache will initiate a repeated SOFTRESET e.g. enable_sysc(). This is true for OMAP3 like platforms that have RESET_DONE status in the SYSSTATUS register and so the the SOFTRESET bit in SYSCONFIG is not automatically cleared. It is not a problem for OMAP4 like platforms that indicate RESET completion by clearing the SOFTRESET bit in the SYSCONFIG register. This repeated SOFTRESET is undesired and was the root cause of USB host issues on OMAP3 platforms when hwmod was allowed to do the SOFTRESET for the USB Host module. To fix this we clear the SOFTRESET bit and update the sysconfig register + sysc_cache using write_sysconfig().

commit 4cb57ab4 upstream. Some module parameters in dm-bufio are read-only. These parameters inform the user about memory consumption. They are not supposed to be changed by the user. However, despite being read-only, these parameters can be set on modprobe or insmod command line, for example: modprobe dm-bufio current_allocated_bytes=12345 The kernel doesn't expect that these variables can be non-zero at module initialization and if the user sets them, it results in BUG. This patch initializes the variables in the module init routine, so that user-supplied values are ignored.

commit 446b8024 upstream. In selinux_ip_postroute() we perform access checks based on the packet's security label. For locally generated traffic we get the packet's security label from the associated socket; this works in all cases except for TCP SYN-ACK packets. In the case of SYN-ACK packet's the correct security label is stored in the connection's request_sock, not the server's socket. Unfortunately, at the point in time when selinux_ip_postroute() is called we can't query the request_sock directly, we need to recreate the label using the same logic that originally labeled the associated request_sock. See the inline comments for more explanation.

commit 47180068 upstream. In selinux_ip_output() we always label packets based on the parent socket. While this approach works in almost all cases, it doesn't work in the case of TCP SYN-ACK packets when the correct label is not the label of the parent socket, but rather the label of the larval socket represented by the request_sock struct. Unfortunately, since the request_sock isn't queued on the parent socket until *after* the SYN-ACK packet is sent, we can't lookup the request_sock to determine the correct label for the packet; at this point in time the best we can do is simply pass/NF_ACCEPT the packet. It must be said that simply passing the packet without any explicit labeling action, while far from ideal, is not terrible as the SYN-ACK packet will inherit any IP option based labeling from the initial connection request so the label *should* be correct and all our access controls remain in place so we shouldn't have to worry about information leaks.

commit 4ef38351 upstream. This patch supports the separate handling of the USB transfer buffer length and the length of the buffer used for multi packet support. For devices supporting multiple report or diagnostic packets, the USB transfer size is now limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the configured report packet size as before. This fixes an issue where event reporting can be delayed for an arbitrary time for multi packet devices. For instance the report size for eGalax devices is defined to the 16 byte maximum diagnostic packet size as opposed to the 5 byte report packet size. In case the driver requests 16 byte from the USB interrupt endpoint, the USB host controller driver needs to split up the request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte. When the first transfer is answered by the eGalax device with not less than the full 8 byte requested, the host controller has got no way of knowing whether the touch controller has got additional data queued and will issue the second transfer. If per example a liftoff event finishes at such a wMaxPacketSize boundary, the data will not be available to the usbtouch driver until a further event is triggered and transfered to the host. From user perspective the BTN_TOUCH release event in this case is stuck until the next touch down event.

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.

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.

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.

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.
