commit 6759dc32 upstream. When the imux entries are rebuilt in alc_rebuild_imux_for_auto_mic(), the initialization of index field is missing. It may work without it casually when the original imux was created by the auto-parser, but it's definitely broken in the case of static configs where no imux was parsed beforehand. Because of this, the auto-mic switching doesn't work properly on some model options. This patch adds the missing initialization of index field. Reported-by:

commit a2987855 upstream. commit 6175ddf0 optimized the mem*io functions that have been used to send commands to the device. these optimizations somehow corrupted the communication with the lx6464es, that resulted the device to be unusable with kernels after 2.6.33. this patch emulates the memcpy_*_io functions via a loop to avoid these problems.

commit 187d333e upstream. VT1708 has no support for unsolicited events per jack-plug, the driver implements the workq for polling the jack-detection. The mixer element "Jack Detect" was supposed to control this behavior on/off, but this doesn't work properly as is now. The workq is always started and the HP automute is always enabled. This patch fixes the jack-detect control behavior by triggering / stopping the work appropriately at the state change. Also the work checks the internal state to continue scheduling or not.

commit 11ed0ba1 upstream. This patch implements a workaround for PL310 erratum 769419. On revisions of the PL310 prior to r3p2, the Store Buffer does not automatically drain. This can cause normal, non-cacheable writes to be retained when the memory system is idle, leading to suboptimal I/O performance for drivers using coherent DMA. This patch adds an optional wmb() call to the cpu_idle loop. On systems with an outer cache, this causes an explicit flush of the store buffer. Acked-by:

commit cc1b0765 upstream. The address spaces, irqs and dma reqs count APIs return the number of corresponding entries in a hwmod including a additional null value or a -1 terminator in the structure introduced recently. More information here: - 212738a4: omap_hwmod: use a terminator record with omap_hwmod_mpu_irqs arrays - 78183f3f: omap_hwmod: use a null structure record to terminate omap_hwmod_addr_space arrays - bc614958: omap_hwmod: use a terminator record with omap_hwmod_dma_info arrays The issue with irqs and dma info was originally reported by Benoit Cousson. The devices which have multiple hwmods and use device_build_ss are broken with this, as their resources are populated with a extra null value, subsequently the probe fails. So fix the API not to include the array terminator in the count. Reported-by:

commit a3283969 upstream. While the OLPC display appears to be able to handle either positive or negative sync, the Display Controller only recognises positive sync. This brings viafb (for XO-1.5) in line with lxfb (for XO-1) and fixes a recent regression where the XO-1.5 DCON could no longer be frozen. Thanks to Florian Tobias Schandinat for helping identify the fix. Test case: from a vt, echo 1 > /sys/devices/platform/dcon/freeze should cause the current screen contents to freeze, rather than garbage being displayed. Signed-off-by:

commit 4cac2eb1 upstream. Previously we claimed device ID 0x7450, regardless of the vendor, which is clearly wrong. Now we'll claim that device ID only for AMD. I suspect this was just a typo in the original code, but it's possible this change will break shpchp on non-7450 AMD bridges. If so, we'll have to fix them as we find them.

commit 04b38670 upstream. When the brightness property is inquired while the backlight is disabled, the driver returns a wrong value (zero) because it probes the value after the backlight was turned off. This caused a black screen even after the backlight is enabled again. It should return the internal backlight_level instead, so that it won't be influenced by the backlight-enable state.

commit 27425286 upstream. This was broken by commit 7759995c (yes, myself). The basic problem here is since the digest state is only saved after the last chunk, the state array is only valid when handling the first chunk of the next buffer. Broken since linux-3.0. Signed-off-by:

commit 0f751e64 upstream. From mhalcrow's original commit message: Characters with ASCII values greater than the size of filename_rev_map[] are valid filename characters. ecryptfs_decode_from_filename() will access kernel memory beyond that array, and ecryptfs_parse_tag_70_packet() will then decrypt those characters. The attacker, using the FNEK of the crafted file, can then re-encrypt the characters to reveal the kernel memory past the end of the filename_rev_map[] array. I expect low security impact since this array is statically allocated in the text area, and the amount of memory past the array that is accessible is limited by the largest possible ASCII filename character. This patch solves the issue reported by mhalcrow but with an implementation suggested by Linus to simply extend the length of filename_rev_map[] to 256. Characters greater than 0x7A are mapped to 0x00, which is how invalid characters less than 0x7A were previously being handled. Signed-off-by:

commit 32001d6f upstream. Dirty pages weren't being written back when an mmap'ed eCryptfs file was closed before the mapping was unmapped. Since f_ops->flush() is not called by the munmap() path, the lower file was simply being released. This patch flushes the eCryptfs file in the vm_ops->close() path. https://launchpad.net/bugs/870326Signed-off-by:

commit b59db43a upstream. The file creation path prematurely called d_instantiate() and unlock_new_inode() before the eCryptfs inode info was fully allocated and initialized and before the eCryptfs metadata was written to the lower file. This could result in race conditions in subsequent file and inode operations leading to unexpected error conditions or a null pointer dereference while attempting to use the unallocated memory. https://launchpad.net/bugs/813146Signed-off-by:

commit 93840ac4 upstream. Function tt_response_fill_table() actually uses a tt_local_entry pointer to iterate either over the local or the global table entries (it depends on the what hash table is passed as argument). To iterate over such entries the hlist_for_each_entry_rcu() macro has to access their "hash_entry" field which MUST be at the same position in both the tt_global/local_entry structures. Reported-by:

commit 9d852393 upstream. In the TT_RESPONSE packet, the number of carried entries is not correctly set. This leads to a wrong interpretation of the packet payload on the receiver side causing random entries to be added to the global translation table. Therefore the latter gets always corrupted, triggering a table recovery all the time. Signed-off-by:

commit 31901264 upstream. Currently the counter of tt_local_entry structures (tt_local_num) is incremented each time the tt_local_reset_flags() is invoked causing the node to send wrong TT_REPONSE packets containing a copy of non-initialised memory thus corrupting other nodes global translation table and making higher level communication impossible.

commit 811c926c upstream. The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. The IN iso stream can only start on the first uframe (0-2 for a 165 us) because of CSPLIT transactions. For the OUT iso stream there no such restriction. uframe 0-5 are possible. The idea of this patch is that the first uframe are precious (for IN TT iso stream) and we should allocate the last uframes first if possible. For that we reverse the order of uframe allocation (last uframe first). Here an example : hid interrupt stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 125 | 39 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- There no place for iso IN stream (uframe 0-2 are used) and we got "cannot submit datapipe for urb 0, error -28: not enough bandwidth" error. With the patch this become. iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- iso IN stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 125 | 40 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- Signed-off-by:

commit 2f640bf4 upstream. The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands; shorter commands must be padded. Simon Detheridge reports that his 3-TB USB disk drive claims to use the 8020i protocol (which is normally meant for ATAPI devices like CD drives), and because of its large size, the disk drive requires the use of 16-byte commands. However the usb_stor_pad12_command() routine in usb-storage always sets the command length to 12, making the drive impossible to use. Since the SFF-8020i specification allows for 16-byte commands in future extensions, we may as well accept them. This patch (as1490) changes usb_stor_pad12_command() to leave commands larger than 12 bytes alone rather than truncating them. Signed-off-by:
