Some firmware exhibits a bug where the same VariableName and VendorGuid values are returned on multiple invocations of GetNextVariableName().

Also disable the workqueue, as efivar_update_sysfs_entries() uses GetNextVariableName() to figure out which variables have been created since the last iteration. That algorithm isn't going to work if GetNextVariableName() returns duplicates. Note that we don't disable EFI variable creation completely on the affected machines, it's just that any pstore dump-* files won't appear in sysfs until the next boot.

It's not wise to assume VariableNameSize represents the length of VariableName, as not all firmware updates VariableNameSize in the same way (some don't update it at all if EFI_SUCCESS is returned). There are even implementations out there that update VariableNameSize with values that are both larger than the string returned in VariableName and smaller than the buffer passed to GetNextVariableName(), which resulted in the following bug report from Michael Schroeder, > On HP z220 system (firmware version 1.54), some EFI variables are > incorrectly named : > > ls -d /sys/firmware/efi/vars/*8be4d* | grep -v -- -8be returns > /sys/firmware/efi/vars/dbxDefault-pport8be4df61-93ca-11d2-aa0d-00e098032b8c > /sys/firmware/efi/vars/KEKDefault-pport8be4df61-93ca-11d2-aa0d-00e098032b8c > /sys/firmware/efi/vars/SecureBoot-pport8be4df61-93ca-11d2-aa0d-00e098032b8c > /sys/firmware/efi/vars/SetupMode-Information8be4df61-93ca-11d2-aa0d-00e098032b8c The issue here is that because we blindly use VariableNameSize without verifying its value, we can potentially read garbage values from the buffer containing VariableName if VariableNameSize is larger than the length of VariableName. Since VariableName is a string, we can calculate its size by searching for the terminating NULL character.

We know that with some firmware implementations writing too much data to UEFI variables can lead to bricking machines. Recent changes attempt to address this issue, but for some it may still be prudent to avoid writing large amounts of data until the solution has been proven on a wide variety of hardware. Crash dumps or other data from pstore can potentially be a large data source. Add a pstore_module parameter to efivars to allow disabling its use as a backend for pstore. Also add a config option, CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE, to allow setting the default value of this paramter to true (i.e. disabled by default).

Add a new option, CONFIG_EFI_VARS_PSTORE, which can be set to N to avoid using efivars as a backend to pstore, as some users may want to compile out the code completely.

There is a more complete atmel patch-series out by Nick Dyer that fixes this and other things, but in the meantime this is the minimal thing to get the touchscreen going on (at least my) Pixel Chromebook. Not that I want my dirty fingers near that beautiful screen, but it seems that a non-initialized touchscreen will also end up being a constant wakeup source, so you have to disable it to go to sleep.

Update proc_ns_follow_link to use nd_jump_link instead of just manually updating nd.path.dentry. This fixes the BUG_ON(nd->inode != parent->d_inode) reported by Dave Jones and reproduced trivially with mkdir /proc/self/ns/uts/a. Sigh it looks like the VFS change to require use of nd_jump_link happend while proc_ns_follow_link was baking and since the common case of proc_ns_follow_link continued to work without problems the need for making this change was overlooked.

This same driver can be used by atmel based touchscreens and touchpads (buttonpads). Platform data may specify a device is a touchpad using the is_tp flag. This will cause the driver to perform some touchpad specific initializations, such as: * register input device name "Atmel maXTouch Touchpad" instead of Touchscreen. * register BTN_LEFT & BTN_TOOL_* event types. * register axis resolution (as a fixed constant, for now) * register BUTTONPAD property * process GPIO buttons using reportid T19 Input event GPIO mapping is done by the platform data key_map array. key_map[x] should contain the KEY or BTN code to send when processing GPIOx from T19.

idr_find(), idr_remove() and idr_replace() used to silently ignore the sign bit and perform lookup with the rest of the bits. The weird behavior has been changed such that negative IDs are treated as invalid. As the behavior change was subtle, WARN_ON_ONCE() was added in the hope of determining who's calling idr functions with negative IDs so that they can be examined for problems. Up until now, all two reported cases are ID number coming directly from userland and getting fed into idr_find() and the warnings seem to cause more problems than being helpful.

Commit ac24c220 ("drm/tegra: Use generic HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select statement for that symbol is a nop. Drop it. What was needed to use HDMI functionality was to select HDMI (which this entry already did through depending on DRM) and to include linux/hdmi.h (which this commit also did).

Renesas boards were consistently defaulting to the 1024x768 resolution, regardless of the native resolution of the monitor plugged in. It was determined that the EDID of the monitor was not being read. Since the DAC is a shared line, in order to read from or write to it we must take control of the DAC clock. This can be done by setting the proper register to one. This bug fix sets the register MGA1064_GEN_IO_CTL2 to one. The DAC control line can be used to determine whether or not a new monitor has been plugged in. But since the hotplug feature is not one we will support, it has been decided to simply leave the register set to one.

A monitor or a user could request a resolution greater than the available VRAM for the backing framebuffer. This change checks the required framebuffer size against the max VRAM size and rejects modes if they are too big. This change can also remove a mode request passed in via the video= parameter.
