2017-06-12drm/vc4/vc4_bo.c: always set bo->resvHans Verkuil
The bo->resv pointer could be NULL, leading to kernel oopses like the one below. This patch ensures that bo->resv is always set in vc4_create_object ensuring that it is never NULL.

2017-06-12i40e: fix handling of HW ATR evictionJacob Keller
A recent commit to refactor the driver and remove the hw_disabled_flags field accidentally introduced two regressions. First, we overwrote pf->flags which removed various key flags including the MSI-X settings. Additionally, it was intended that we have now two flags, HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done, and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere. This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely updates pf->flags instead of overwriting it. Without this patch we will have many problems including disabling MSI-X support, and we'll attempt to use HW ATR eviction on devices which do not support it.

2017-06-12x86/debug: Handle early WARN_ONs properPeter Zijlstra
Hans managed to trigger a WARN very early in the boot which killed his (Virtual) box. The reason is that the recent rework of WARN() to use UD0 forgot to add the fixup_bug() call to early_fixup_exception(). As a result the kernel does not handle the WARN_ON injected UD0 exception and panics. Add the missing fixup call, so early UD's injected by WARN() get handled.

2017-06-12drm/i915: Pass atomic state to backlight enable/disable/set callbacks.Maarten Lankhorst
Pass crtc_state to the enable callback, and connector_state to all callbacks. This will eliminate the need to guess for the correct pipe in these callbacks. The crtc state is required for pch_enable_backlight to obtain the correct cpu_transcoder. intel_dp_aux_backlight's setup function is called before hw readout, so crtc_state and connector_state->best_encoder are NULL in the enable() and set() callbacks.

2017-06-12usb: xhci: Fix USB 3.1 supported protocol parsingYD Tseng
xHCI host controllers can have both USB 3.1 and 3.0 extended speed protocol lists. If the USB3.1 speed is parsed first and 3.0 second then the minor revision supported will be overwritten by the 3.0 speeds and the USB3 roothub will only show support for USB 3.0 speeds. This was the case with a xhci controller with the supported protocol capability listed below. In xhci-mem.c, the USB 3.1 speed is parsed first, the min_rev of usb3_rhub is set as 0x10. And then USB 3.0 is parsed. However, the min_rev of usb3_rhub will be changed to 0x00. If USB 3.1 device is connected behind this host controller, the speed of USB 3.1 device just reports 5G speed using lsusb. 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 00 01 08 00 00 00 00 00 40 00 00 00 00 00 00 00 00 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20 02 08 10 03 55 53 42 20 01 02 00 00 00 00 00 00 //USB 3.1 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 40 02 08 00 03 55 53 42 20 03 06 00 00 00 00 00 00 //USB 3.0 50 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 60 02 08 00 02 55 53 42 20 09 0E 19 00 00 00 00 00 //USB 2.0 70 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 This patch fixes the issue by only owerwriting the minor revision if it is higher than the existing one.

2017-06-12cpufreq: conservative: Allow down_threshold to take values from 1 to 10Tomasz Wilczyński
Commit 27ed3cd2ebf4 (cpufreq: conservative: Fix the logic in frequency decrease checking) removed the 10 point substraction when comparing the load against down_threshold but did not remove the related limit for the down_threshold value. As a result, down_threshold lower than 11 is not allowed even though values from 1 to 10 do work correctly too. The comment ("cannot be lower than 11 otherwise freq will not fall") also does not apply after removing the substraction. For this reason, allow down_threshold to take any value from 1 to 99 and fix the related comment.

2017-06-12ACPICA: Tables: Mechanism to handle late stage acpi_get_table() imbalanceLv Zheng
Considering this case: 1. A program opens a sysfs table file 65535 times, it can increase validation_count and first increment cause the table to be mapped: validation_count = 65535 2. AML execution causes "Load" to be executed on the same table, this time it cannot increase validation_count, so validation_count remains: validation_count = 65535 3. The program closes sysfs table file 65535 times, it can decrease validation_count and the last decrement cause the table to be unmapped: validation_count = 0 4. AML code still accessing the loaded table, kernel crash can be observed. To prevent that from happening, add a validation_count threashold. When it is reached, the validation_count can no longer be incremented/decremented to invalidate the table descriptor (means preventing table unmappings) Note that code added in acpi_tb_put_table() is actually a no-op but changes the warning message into a "warn once" one.

This patch closes a long standing race in configfs between the creation of a new symlink in create_link(), while the symlink target's config_item is being concurrently removed via configfs_rmdir(). This can happen because the symlink target's reference is obtained by config_item_get() in create_link() before the CONFIGFS_USET_DROPPING bit set by configfs_detach_prep() during configfs_rmdir() shutdown is actually checked..

git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull key subsystem fixes from James Morris: "Here are a bunch of fixes for Linux keyrings, including: - Fix up the refcount handling now that key structs use the refcount_t type and the refcount_t ops don't allow a 0->1 transition. - Fix a potential NULL deref after error in x509_cert_parse(). - Don't put data for the crypto algorithms to use on the stack. - Fix the handling of a null payload being passed to add_key(). - Fix incorrect cleanup an uninitialised key_preparsed_payload in key_update(). - Explicit sanitisation of potentially secure data before freeing. - Fixes for the Diffie-Helman code" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (23 commits) KEYS: fix refcount_inc() on zero KEYS: Convert KEYCTL_DH_COMPUTE to use the crypto KPP API crypto : asymmetric_keys : verify_pefile:zero memory content before freeing KEYS: DH: add __user annotations to keyctl_kdf_params KEYS: DH: ensure the KDF counter is properly aligned KEYS: DH: don't feed uninitialized "otherinfo" into KDF KEYS: DH: forbid using digest_null as the KDF hash KEYS: sanitize key structs before freeing KEYS: trusted: sanitize all key material KEYS: encrypted: sanitize all key material KEYS: user_defined: sanitize key payloads KEYS: sanitize add_key() and keyctl() key payloads KEYS: fix freeing uninitialized memory in key_update() KEYS: fix dereferencing NULL payload with nonzero length KEYS: encrypted: use constant-time HMAC comparison KEYS: encrypted: fix race causing incorrect HMAC calculations KEYS: encrypted: fix buffer overread in valid_master_desc() KEYS: encrypted: avoid encrypting/decrypting stack buffers KEYS: put keyring if install_session_keyring_to_cred() fails KEYS: Delete an error message for a failed memory allocation in get_derived_key() ...
