2016-10-31mpt3sas: Don't spam logs if logging level is 0Johannes Thumshirn
commit 0d667f72b2a20bbac72bec0ab11467fc70bb0f1f upstream. In _scsih_io_done() we test if the ioc->logging_level does _not_ have the MPT_DEBUG_REPLY bit set and if it hasn't we print the debug messages. This unfortunately is the wrong way around. Note, the actual bug is older than af0094115 but this commit removed the CONFIG_SCSI_MPT3SAS_LOGGING Kconfig option which hid the bug.

2016-10-31clk: divider: Fix clk_divider_round_rate() to use clk_readl()Geert Uytterhoeven
commit 2cf9a57811bddb6fa6b0f8d7376da164d5534813 upstream. clk-divider uses clk_readl()/clk_writel() everywhere, except in clk_divider_round_rate(), where plain readl() is used.

2016-10-31s390/con3270: fix insufficient space paddingSascha Silbe
commit 6cd997db911f28f2510b771691270c52b63ed2e6 upstream. con3270 contains an optimisation that reduces the amount of data to be transmitted to the 3270 terminal by putting a Repeat to Address (RA) order into the data stream. The RA order itself takes up space, so con3270 only uses it if there's enough space left in the line buffer. Otherwise it just pads out the line manually. For lines that were _just_ short enough that the RA order still fit in the line buffer, the line was instead padded with an insufficient amount of spaces. This was caused by examining the size of the allocated line buffer rather than the length of the string to be displayed. For con3270_cline_end(), we just compare against the line length. For con3270_update_string() however that isn't available anymore, so we check whether the Repeat to Address order is present. Fixes: f51320a5 ("[PATCH] s390: new 3270 driver.")

2016-10-31s390/con3270: fix use of uninitialised dataSascha Silbe
commit c14f2aac7aa147861793eed9f41f91dd530f0be1 upstream. con3270 contains an optimisation that reduces the amount of data to be transmitted to the 3270 terminal by putting a Repeat to Address (RA) order into the data stream. The RA order itself takes up space, so con3270 only uses it if there's enough space left in the line buffer. Otherwise it just pads out the line manually. For lines too long to include the RA order, one byte was left uninitialised. This was caused by an off-by-one bug in the loop that pads out the line. Since the buffer is allocated from a common pool, the single byte left uninitialised contained some previous buffer content. Usually this was just a space or some character (which can result in clutter but is otherwise harmless). Sometimes, however, it was a Repeat to Address order, messing up the entire screen layout and causing the display to send the entire buffer content on every keystroke.

commit d53c51f26145657aa7c55fa396f93677e613548d upstream. Since commit 9f3d6d7 chsc_get_channel_measurement_chars is called with interrupts disabled during resume from hibernate. Since this function used spin_unlock_irq, interrupts have been enabled accidentally. Fix this by using the irqsave variant.

commit 86c7e6836479c4045a9a81ed5ea76c51d719f9c1 upstream. A workaround for a warning introduced a use of the NO_IRQ macro that should have been gone for a long time.

commit 4d31a2588ae37a5d0f61f4d956454e9504846aeb upstream. The variable i contains a total number of resources (including IORESOURCE_IRQ). However, we want the dmem_region_start to point after the last resource of type IORESOURCE_MEM. The original behaviour leads (very likely) to skipping several UIO mapping regions and makes them useless.

commit ded89912156b1a47d940a0c954c43afbabd0c42c upstream. User-space can choose to omit NL80211_ATTR_SSID and only provide raw IE TLV data. When doing so it can provide SSID IE with length exceeding the allowed size. The driver further processes this IE copying it into a local variable without checking the length.

2016-10-31drm/i915: Account for TSEG size when determining 865G stolen baseVille Syrjälä
commit d721b02fd00bf133580f431b82ef37f3b746dfb2 upstream. Looks like the TSEG lives just above TOUD, stolen comes after TSEG. The spec seems somewhat self-contradictory in places, in the ESMRAMC register desctription it says: TSEG Size: 10=(TOUD + 512 KB) to TOUD 11 =(TOUD + 1 MB) to TOUD so that agrees with TSEG being at TOUD. But the example given elsehwere in the spec says: TOUD equals 62.5 MB = 03E7FFFFh TSEG selected as 512 KB in size, Graphics local memory selected as 1 MB in size General System RAM available in system = 62.5 MB General system RAM range00000000h to 03E7FFFFh TSEG address range03F80000h to 03FFFFFFh TSEG pre-allocated from03F80000h to 03FFFFFFh Graphics local memory pre-allocated from03E80000h to 03F7FFFFh so here we have TSEG above stolen. Real world evidence agrees with the TOUD->TSEG->stolen order however, so let's fix up the code to account for the TSEG size.

2016-10-31Revert "drm/i915: Check live status before reading edid"David Weinehall
commit 23f889bdf6ee5cfff012d8b09f6bec920c691696 upstream. This reverts commit 237ed86c693d8a8e4db476976aeb30df4deac74b. Our current implementation of live status check (repeat 9 times with 10ms delays between each attempt as a workaround for buggy displays) imposes a rather serious penalty, time wise, on intel_hdmi_detect(). Since we we already skip live status checks on platforms before gen 7, and since we seem to have coped quite well before the live status check was introduced for newer platforms too, the previous behaviour is probably preferable, at least unless someone can point to a use-case that the live status check improves (apart from "Bspec says so".)

However, drm_gem_prime_export() was passing its own THIS_MODULE (i.e. drm.ko) rather than the driver. Extract the right owner from the device->fops instead. v2: Use C99 initializers to zero out unset elements of dma_buf_export_info v3: Extract the right module from dev->fops.

2016-10-28target: Don't override EXTENDED_COPY xcopy_pt_cmd SCSI status codeDinesh Israni
commit 926317de33998c112c5510301868ea9aa34097e2 upstream. This patch addresses a bug where a local EXTENDED_COPY WRITE or READ backend I/O request would always return SAM_STAT_CHECK_CONDITION, even if underlying xcopy_pt_cmd->se_cmd generated a different SCSI status code. ESX host environments expect to hit SAM_STAT_RESERVATION_CONFLICT for certain scenarios, and SAM_STAT_CHECK_CONDITION results in non-retriable status for these cases. Tested on v4.1.y with ESX v5.5u2+ with local IBLOCK backend copy.

2016-10-28target: Make EXTENDED_COPY 0xe4 failure return COPY TARGET DEVICE NOT REACHABLENicholas Bellinger
commit 449a137846c84829a328757cd21fd9ca65c08519 upstream. This patch addresses a bug where EXTENDED_COPY across multiple LUNs results in a CHECK_CONDITION when the source + destination are not located on the same physical node. ESX Host environments expect sense COPY_ABORTED w/ COPY TARGET DEVICE NOT REACHABLE to be returned when this occurs, in order to signal fallback to local copy method. As described in section 6.3.3 of spc4r22: "If it is not possible to complete processing of a segment because the copy manager is unable to establish communications with a copy target device, because the copy target device does not respond to INQUIRY, or because the data returned in response to INQUIRY indicates an unsupported logical unit, then the EXTENDED COPY command shall be terminated with CHECK CONDITION status, with the sense key set to COPY ABORTED, and the additional sense code set to COPY TARGET DEVICE NOT REACHABLE." Tested on v4.1.y with ESX v5.5u2+ with BlockCopy across multiple nodes.

2016-10-28target: Re-add missing SCF_ACK_KREF assignment in v4.1.yNicholas Bellinger
commit 527268df31e57cf2b6d417198717c6d6afdb1e3e upstream. This patch fixes a regression in >= v4.1.y code where the original SCF_ACK_KREF assignment in target_get_sess_cmd() was dropped upstream in commit 054922bb, but the series for addressing TMR ABORT_TASK + LUN_RESET with fabric session reinstatement in commit febe562c20 still depends on this code in transport_cmd_finish_abort(). The regression manifests itself as a se_cmd->cmd_kref +1 leak, where ABORT_TASK + LUN_RESET can hang indefinately for a specific I_T session for drivers using SCF_ACK_KREF, resulting in hung kthreads. This patch has been verified with v4.1.y code.

commit 4f48aa7a11bfed9502a7c85a5b68cd40ea827f73 upstream. Accesses of the rtsx sdmmc's parent device, which is the rtsx usb device, must be done when it's runtime resumed.

2016-10-28net/mlx4_core: Allow resetting VF admin mac to zeroJack Morgenstein
commit 6e5224224faa50ec4c8949dcefadf895e565f0d1 upstream. The VF administrative mac addresses (stored in the PF driver) are initialized to zero when the PF driver starts up. These addresses may be modified in the PF driver through ndo calls initiated by iproute2 or libvirt. While we allow the PF/host to change the VF admin mac address from zero to a valid unicast mac, we do not allow restoring the VF admin mac to zero. We currently only allow changing this mac to a different unicast mac. This leads to problems when libvirt scripts are used to deal with VF mac addresses, and libvirt attempts to revoke the mac so this host will not use it anymore. Fix this by allowing resetting a VF administrative MAC back to zero.

2016-10-28hpsa: correct skipping masked peripheralsDon Brace
commit 64ce60cab24603ac0fcd59c9fbc3be78f4c4d229 upstream. The SA controller spins down RAID drive spares. A REGNEWD event causes an inquiry to be sent to all physical drives. This causes the SA controller to spin up the spare. The controller suspends all I/O to a logical volume until the spare is spun up. The spin-up can take over 50 seconds. This can result in one or both of the following: - SML sends down aborts and resets to the logical volume and can cause the logical volume to be off-lined. - a negative impact on the logical volume's I/O performance each time a REGNEWD is triggered.

commit bcd8f2e94808fcddf6ef3af5f060a36820dcc432 upstream. This patch fixes one use-after-free report[1] by KASAN. In __scsi_scan_target(), when a type 31 device is probed, SCSI_SCAN_TARGET_PRESENT is returned and the target will be scanned again. Inside the following scsi_report_lun_scan(), one new scsi_device instance is allocated, and scsi_probe_and_add_lun() is called again to probe the target and still see type 31 device, finally __scsi_remove_device() is called to remove & free the device at the end of scsi_probe_and_add_lun(), so cause use-after-free in scsi_report_lun_scan(). And the following SCSI log can be observed: scsi 0:0:2:0: scsi scan: INQUIRY pass 1 length 36 scsi 0:0:2:0: scsi scan: INQUIRY successful with code 0x0 scsi 0:0:2:0: scsi scan: peripheral device type of 31, no device added scsi 0:0:2:0: scsi scan: Sending REPORT LUNS to (try 0) scsi 0:0:2:0: scsi scan: REPORT LUNS successful (try 0) result 0x0 scsi 0:0:2:0: scsi scan: REPORT LUN scan scsi 0:0:2:0: scsi scan: INQUIRY pass 1 length 36 scsi 0:0:2:0: scsi scan: INQUIRY successful with code 0x0 scsi 0:0:2:0: scsi scan: peripheral device type of 31, no device added BUG: KASAN: use-after-free in __scsi_scan_target+0xbf8/0xe40 at addr ffff88007b44a104 This patch fixes the issue by moving the putting reference at the end of scsi_report_lun_scan().

commit 62837b3c1a95535d1a287c9c8c6563bbd8d37033 upstream. Another Lifebook machine that needs the same quirk as other similar models to make the driver working. Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries are in alphabetical order.

2016-10-28Input: elantech - force needed quirks on Fujitsu H760Matti Kurkela
commit f9a703a54d16ba2470391c4b12236ee56591d50c upstream. Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with the same quirks. Without this patch, the touchpad is useless out-of-the-box as the mouse pointer won't move. This patch makes the driver aware of both the crc_enabled=1 requirement and the middle button, making the touchpad fully functional out-of-the-box.

2016-10-28Input: i8042 - skip selftest on ASUS laptopsMarcos Paulo de Souza
commit 930e19248e9b61da36c967687ca79c4d5f977919 upstream. On suspend/resume cycle, selftest is executed to reset i8042 controller. But when this is done in Asus devices, subsequent calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus, let's avoid running selftests on them. All models affected by this problem: A455LD K401LB K501LB K501LX R409L V502LX X302LA X450LCP X450LD X455LAB X455LDB X455LF Z450LA [1]: https://marc.info/?l=linux-input&m=144312209020616&w=2 Fixes: "ETPS/2 Elantech Touchpad dies after resume from suspend" (https://bugzilla.kernel.org/show_bug.cgi?id=107971) Signed-off-by: Marcos Paulo de Souza <marcos.souza.org@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-10-28cx231xx: fix GPIOs for Pixelview SBTVD hybridMauro Carvalho Chehab
commit 24b923f073ac37eb744f56a2c7f77107b8219ab2 upstream. This device uses GPIOs: 28 to switch between analog and digital modes: on digital mode, it should be set to 1. The code that sets it on analog mode is OK, but it misses the logic that sets it on digital mode.
