2017-01-20ARM: dts: da850-evm: fix read access to SPI flashFabien Parent1-0/+1
Read access to the SPI flash are broken on da850-evm, i.e. the data read is not what is actually programmed on the flash. According to the datasheet for the M25P64 part present on the da850-evm, if the SPI frequency is higher than 20MHz then the READ command is not usable anymore and only the FAST_READ command can be used to read data. This commit specifies in the DTS that we should use FAST_READ command instead of the READ command.

2017-01-19arm64: avoid returning from bad_modeMark Rutland2-5/+25
Generally, taking an unexpected exception should be a fatal event, and bad_mode is intended to cater for this. However, it should be possible to contain unexpected synchronous exceptions from EL0 without bringing the kernel down, by sending a SIGILL to the task. We tried to apply this approach in commit 9955ac47f4ba1c95 ("arm64: don't kill the kernel on a bad esr from el0"), by sending a signal for any bad_mode call resulting from an EL0 exception. However, this also applies to other unexpected exceptions, such as SError and FIQ. The entry paths for these exceptions branch to bad_mode without configuring the link register, and have no kernel_exit. Thus, if we take one of these exceptions from EL0, bad_mode will eventually return to the original user link register value. This patch fixes this by introducing a new bad_el0_sync handler to cater for the recoverable case, and restoring bad_mode to its original state, whereby it calls panic() and never returns. The recoverable case branches to bad_el0_sync with a bl, and returns to userspace via the usual ret_to_user mechanism.

2017-01-19HID: wacom: Fix sibling detection regressionJason Gerecke2-8/+18
Commit 345857b ("HID: wacom: generic: Add support for sensor offsets") included a change to the operation and location of the call to 'wacom_add_shared_data' in 'wacom_parse_and_register'. The modifications included moving it higher up so that it would occur before the call to 'wacom_retrieve_hid_descriptor'. This was done to prevent a crash that would have occured when the report containing tablet offsets was fed into the driver with 'wacom_hid_report_raw_event' (specifically: the various 'wacom_wac_*_report' functions were written with the assumption that they would only be called once tablet setup had completed; 'wacom_wac_pen_report' in particular dereferences 'shared' which wasn't yet allocated). Moving the call to 'wacom_add_shared_data' effectively prevented the crash but also broke the sibiling detection code which assumes that the HID descriptor has been read and the various device_type flags set. To fix this situation, we restore the original 'wacom_add_shared_data' operation and location and instead implement an alternative change that can also prevent the crash. Specifically, we notice that the report functions mentioned above expect to be called only for input reports. By adding a check, we can prevent feature reports (such as the offset report) from causing trouble.

The extension is necessary right now because we need a proper way to unbreak LTTNG, which iscurrently non functional due to the removal of the notifiers. Surely it's out of tree, but it's widely used by distros. The simple solution would have been to reserve a state for LTTNG, but I'm not fond about unused crap in the kernel and the dynamic range, which we admittedly should have done right away, allows us to remove quite some of the hardcoded states, i.e. those which have no ordering requirements.

2017-01-18ovl: fix possible use after free on redirect dir lookupAmir Goldstein1-9/+18
ovl_lookup_layer() iterates on path elements of d->name.name but also frees and allocates a new pointer for d->name.name. For the case of lookup in upper layer, the initial d->name.name pointer is stable (dentry->d_name), but for lower layers, the initial d->name.name can be d->redirect, which can be freed during iteration. [SzM] Keep the count of remaining characters in the redirect path and calculate the current position from that. This works becuase only the prefix is modified, the ending always stays the same.

2017-01-17ARM64: dts: meson-gxbb-odroidc2: Disable SCPI DVFSNeil Armstrong2-1/+5
The current hardware is not able to run with all cores enabled at a cluster frequency superior at 1536MHz. But the currently shipped u-boot for the platform still reports an OPP table with possible DVFS frequency up to 2GHz, and will not change since the off-tree linux tree supports limiting the OPPs with a kernel parameter. A recent u-boot change reports the boot-time DVFS around 100MHz and the default performance cpufreq governor sets the maximum frequency. Previous version of u-boot reported to be already at the max OPP and left the OPP as is. Nevertheless, other governors like ondemand could setup the max frequency and make the system crash. This patch disables the DVFS clock and disables cpufreq.

2017-01-17xfs: don't wrap ID in xfs_dq_get_next_idEric Sandeen1-0/+4
The GETNEXTQOTA ioctl takes whatever ID is sent in, and looks for the next active quota for an user equal or higher to that ID. But if we are at the maximum ID and then ask for the "next" one, we may wrap back to zero. In this case, userspace may loop forever, because it will start querying again at zero. We'll fix this in userspace as well, but for the kernel, return -ENOENT if we ask for the next quota ID past UINT_MAX so the caller knows to stop.

2017-01-17xfs: sanity check inode mode when creating new dentryAmir Goldstein1-9/+39
The helper xfs_dentry_to_name() is used by 2 different classes of callers: Callers that pass zero mode and don't care about the returned name.type field and Callers that pass non zero mode and do care about the name.type field. Change xfs_dentry_to_name() to not take the mode argument and change the call sites of the first class to not pass the mode argument. Create a new helper xfs_dentry_mode_to_name() which does pass the mode argument and returns -EFSCORRUPTED if mode is invalid. Callers that translate non zero mode to on-disk file type now check the return value and will export the error to user instead of staging an invalid file type to be written to directory entry.

2017-01-17xfs: sanity check directory inode di_sizeAmir Goldstein2-3/+7
This changes fixes an assertion hit when fuzzing on-disk i_mode values. The easy case to fix is when changing an empty file i_mode to S_IFDIR. In this case, xfs_dinode_verify() detects an illegal zero size for directory and fails to load the inode structure from disk. For the case of non empty file whose i_mode is changed to S_IFDIR, the ASSERT() statement in xfs_dir2_isblock() is replaced with return -EFSCORRUPTED, to avoid interacting with corrupted jusk also when XFS_DEBUG is disabled.

2017-01-17scsi: mpt3sas: fix hang on ata passthrough commandsJames Bottomley2-14/+38
mpt3sas has a firmware failure where it can only handle one pass through ATA command at a time. If another comes in, contrary to the SAT standard, it will hang until the first one completes (causing long commands like secure erase to timeout). The original fix was to block the device when an ATA command came in, but this caused a regression with commit 669f044170d8933c3d66d231b69ea97cb8447338 Author: Bart Van Assche <bart.vanassche@sandisk.com> Date: Tue Nov 22 16:17:13 2016 -0800 scsi: srp_transport: Move queuecommand() wait code to SCSI core So fix the original fix of the secure erase timeout by properly returning SAM_STAT_BUSY like the SAT recommends.
