commit ebc80840 upstream. The Fimware 8.1 has a bug in which the extra buttons are only sent when the ExtBit is 1. This should be fixed in a future FW update which should have a bump of the minor version. Signed-off-by:

commit dc5465dc upstream. On the X1 Carbon 3rd gen (with a 2015 broadwell cpu), the physical middle button of the trackstick (attached to the touchpad serio device, of course) seems to get lost. Actually, the touchpads reports 3 extra buttons, which falls in the switch below to the '2' case. Let's handle the case of odd numbers also, so that the middle button finds its way back.

commit ac097930 upstream. Query the min dimensions even if the check SYN_EXT_CAP_REQUESTS(priv->capabilities) >= 7 fails, but we know that the firmware version 8.1 is safe. With that we don't need quirks for post-2013 models anymore as they expose correct min and max dimensions. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=91541Signed-off-by:

commit e8932869 upstream. On gcc5 the kernel does not link: ld: .eh_frame_hdr table[4] FDE at 0000000000000648 overlaps table[5] FDE at 0000000000000670. Because prior GCC versions always emitted NOPs on ALIGN directives, but gcc5 started omitting them. .LSTARTFDEDLSI1 says: /* HACK: The dwarf2 unwind routines will subtract 1 from the return address to get an address in the middle of the presumed call instruction. Since we didn't get here via a call, we need to include the nop before the real start to make up for it. */ .long .LSTART_sigreturn-1-. /* PC-relative start address */ But commit 69d0627a ("x86 vDSO: reorder vdso32 code") from 2.6.25 replaced .org __kernel_vsyscall+32,0x90 by ALIGN right before __kernel_sigreturn. Of course, ALIGN need not generate any NOP in there. Esp. gcc5 collapses vclock_gettime.o and int80.o together with no generated NOPs as "ALIGN". So fix this by adding to that point at least a single NOP and make the function ALIGN possibly with more NOPs then. Kudos for reporting and diagnosing should go to Richard. Reported-by:

commit aa75ebc2 upstream. Some APs experience problems when working with U-APSD. Decreasing the probability of that happening by using legacy mode for all ACs but VO isn't enough. Cisco 4410N originally forced us to enable VO by default only because it treated non-VO ACs as legacy. However some APs (notably Netgear R7000) silently reclassify packets to different ACs. Since u-APSD ACs require trigger frames for frame retrieval clients would never see some frames (e.g. ARP responses) or would fetch them accidentally after a long time. It makes little sense to enable u-APSD queues by default because it needs userspace applications to be aware of it to actually take advantage of the possible additional powersavings. Implicitly depending on driver autotrigger frame support doesn't make much sense. Signed-off-by:

commit 9d239d35 upstream. The commit d297933c (spi: dw: Fix detecting FIFO depth) tries to fix the logic of the FIFO detection based on the description on the comments. However, there is a slight difference between numbers in TX Level and TX FIFO size. So, by specification the FIFO size would be in a range 2-256 bytes. From TX Level prospective it means we can set threshold in the range 0-(FIFO size - 1) bytes. Hence there are currently two issues: a) FIFO size 2 bytes is actually skipped since TX Level is 1 bit and could be either 0 or 1 byte; b) FIFO size is incorrectly decreased by 1 which already done by meaning of TX Level register. This patch fixes it eventually right. Fixes: d297933c (spi: dw: Fix detecting FIFO depth) Reviewed-by:

commit 528c943f upstream. ip_vs_conn_fill_param_sync() gets in param.pe a module reference for persistence engine from __ip_vs_pe_getbyname() but forgets to put it. Problem occurs in backup for sync protocol v1 (2.6.39). Also, pe_data usually comes in sync messages for connection templates and ip_vs_conn_new() copies the pointer only in this case. Make sure pe_data is not leaked if it comes unexpectedly for normal connections. Leak can happen only if bogus messages are sent to backup server.

commit 79fbf4a5 upstream. Fix overflow bug in tty_wait_until_sent on 64-bit machines, where an infinite timeout (0) would be passed to the underlying tty-driver's wait_until_sent-operation as a negative timeout (-1), causing it to return immediately. This manifests itself for example as tcdrain() returning immediately, drivers not honouring the drain flags when setting terminal attributes, or even dropped data on close as a requested infinite closing-wait timeout would be ignored. The first symptom was reported by Asier LLANO who noted that tcdrain() returned prematurely when using the ftdi_sio usb-serial driver. Fix this by passing 0 rather than MAX_SCHEDULE_TIMEOUT (LONG_MAX) to the underlying tty driver. Note that the serial-core wait_until_sent-implementation is not affected by this bug due to a lucky chance (comparison to an unsigned maximum timeout), and neither is the cyclades one that had an explicit check for negative timeouts, but all other tty drivers appear to be affected.

commit f0bf0bd0 upstream. This problem was taken care of three times already in * b0de59b5 (TTY: do not update atime/mtime on read/write), * 37b7f3c7 (TTY: fix atime/mtime regression), and * b0b88565 (tty: fix up atime/mtime mess, take three) But it still misses one point. As John Paul correctly points out, we do not care about setting date. If somebody ever changes wall time backwards (by mistake for example), tty timestamps are never updated until the original wall time passes. So check the absolute difference of times and if it large than "8 seconds or so", always update the time. That means we will update immediatelly when changing time. Ergo, CAP_SYS_TIME can foul the check, but it was always that way. Thanks John for serving me this so nicely debugged. Signed-off-by:

commit b8cb91e0 upstream. The xhci in Intel Sunrisepoint and Cherryview platforms need a driver workaround for a Stuck PME that might either block PME events in suspend, or create spurious PME events preventing runtime suspend. Workaround is to clear a internal PME flag, BIT(28) in a vendor specific PMCTRL register at offset 0x80a4, in both suspend resume callbacks Without this, xhci connected usb devices might never be able to wake up the system from suspend, or prevent device from going to suspend (xhci d3) Signed-off-by:

commit 45ba2154 upstream. When a control transfer has a short data stage, the xHCI controller generates two transfer events: a COMP_SHORT_TX event that specifies the untransferred amount, and a COMP_SUCCESS event. But when the data stage is not short, only the COMP_SUCCESS event occurs. Therefore, xhci-hcd must set urb->actual_length to urb->transfer_buffer_length while processing the COMP_SUCCESS event, unless urb->actual_length was set already by a previous COMP_SHORT_TX event. The driver checks this by seeing whether urb->actual_length == 0, but this alone is the wrong test, as it is entirely possible for a short transfer to have an urb->actual_length = 0. This patch changes the xhci driver to rely on a new td->urb_length_set flag, which is set to true when a COMP_SHORT_TX event is received and the URB length updated at that stage. This fixes a bug which affected the HSO plugin, which relies on URBs with urb->actual_length == 0 to halt re-submitting the RX URB in the control endpoint. Signed-off-by:

commit 956421fb upstream. 'ret_from_fork' checks TIF_IA32 to determine whether 'pt_regs' and the related state make sense for 'ret_from_sys_call'. This is entirely the wrong check.

commit 6d65261a upstream. eCryptfs can't be aware of what to expect when after passing an arbitrary ioctl command through to the lower filesystem. The ioctl command may trigger an action in the lower filesystem that is incompatible with eCryptfs. One specific example is when one attempts to use the Btrfs clone ioctl command when the source file is in the Btrfs filesystem that eCryptfs is mounted on top of and the destination fd is from a new file created in the eCryptfs mount. The ioctl syscall incorrectly returns success because the command is passed down to Btrfs which thinks that it was able to do the clone operation. However, the result is an empty eCryptfs file. This patch allows the trim, {g,s}etflags, and {g,s}etversion ioctl commands through and then copies up the inode metadata from the lower inode to the eCryptfs inode to catch any changes made to the lower inode's metadata. Those five ioctl commands are mostly common across all filesystems but the whitelist may need to be further pruned in the future. https://bugzilla.kernel.org/show_bug.cgi?id=93691 https://launchpad.net/bugs/1305335Signed-off-by:

commit c7d373c3 upstream. This patch integrates Cyber Cortex AV boards with the existing ftdi_jtag_quirk in order to use serial port 0 with JTAG which is required by the manufacturers' software. Steps: 2 [ftdi_sio_ids.h] 1. Defined the device PID [ftdi_sio.c] 2. Added a macro declaration to the ids array, in order to enable the jtag quirk for the device. Signed-off-by:

commit 957ed60b upstream. Each inode of nilfs2 stores a root node of a b-tree, and it turned out to have a memory overrun issue: Each b-tree node of nilfs2 stores a set of key-value pairs and the number of them (in "bn_nchildren" member of nilfs_btree_node struct), as well as a few other "bn_*" members. Since the value of "bn_nchildren" is used for operations on the key-values within the b-tree node, it can cause memory access overrun if a large number is incorrectly set to "bn_nchildren". For instance, nilfs_btree_node_lookup() function determines the range of binary search with it, and too large "bn_nchildren" leads nilfs_btree_node_get_key() in that function to overrun. As for intermediate b-tree nodes, this is prevented by a sanity check performed when each node is read from a drive, however, no sanity check has been done for root nodes stored in inodes. This patch fixes the issue by adding missing sanity check against b-tree root nodes so that it's called when on-memory inodes are read from ifile, inode metadata file. Signed-off-by:
