patch "staging: vchiq_arm: fix compat VCHIQ_IOC_AWAIT_COMPLETION" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled staging: vchiq_arm: fix compat VCHIQ_IOC_AWAIT_COMPLETION to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 5a96b2d38dc054c0bbcbcd585b116566cbd877fe Mon Sep 17 00:00:00 2001 From: Ben Wolsieffer <benwolsieffer(a)gmail.com> Date: Sat, 3 Nov 2018 19:32:20 -0400 Subject: staging: vchiq_arm: fix compat VCHIQ_IOC_AWAIT_COMPLETION The compatibility ioctl wrapper for VCHIQ_IOC_AWAIT_COMPLETION assumes that the native ioctl always uses a message buffer and decrements msgbufcount. Certain message types do not use a message buffer and in this case msgbufcount is not decremented, and completion->header for the message is NULL. Because the wrapper unconditionally decrements msgbufcount, the calling process may assume that a message buffer has been used even when it has not. This results in a memory leak in the userspace code that interfaces with this driver. When msgbufcount is decremented, the userspace code assumes that the buffer can be freed though the reference in completion->header, which cannot happen when the reference is NULL. This patch causes the wrapper to only decrement msgbufcount when the native ioctl decrements it. Note that we cannot simply copy the native ioctl's value of msgbufcount, because the wrapper only retrieves messages from the native ioctl one at a time, while userspace may request multiple messages. See https://github.com/raspberrypi/linux/pull/2703 for more discussion of this patch.

[PATCH] x86/mm/pat: Fix missing preemption disable for __native_flush_tlb()

by Dan Williams

Commit f77084d96355 "x86/mm/pat: Disable preemption around __flush_tlb_all()" addressed a case where __flush_tlb_all() is called without preemption being disabled. It also left a warning to catch other cases where preemption is not disabled. That warning triggers for the memory hotplug path which is also used for persistent memory enabling: WARNING: CPU: 35 PID: 911 at ./arch/x86/include/asm/tlbflush.h:460 RIP: 0010:__flush_tlb_all+0x1b/0x3a [..] Call Trace: phys_pud_init+0x29c/0x2bb kernel_physical_mapping_init+0xfc/0x219 init_memory_mapping+0x1a5/0x3b0 arch_add_memory+0x2c/0x50 devm_memremap_pages+0x3aa/0x610 pmem_attach_disk+0x585/0x700 [nd_pmem] Rather than audit all __flush_tlb_all() callers to add preemption, just do it internally to __flush_tlb_all().

[PATCH V2] x86/speculation: Support Enhanced IBRS on future CPUs

by Sai Praneeth Prakhya

From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com> [ Upstream commit 706d51681d636a0c4a5ef53395ec3b803e45ed4d ] Future Intel processors will support "Enhanced IBRS" which is an "always on" mode i.e. IBRS bit in SPEC_CTRL MSR is enabled once and never disabled. >From the specification [1]: "With enhanced IBRS, the predicted targets of indirect branches executed cannot be controlled by software that was executed in a less privileged predictor mode or on another logical processor. As a result, software operating on a processor with enhanced IBRS need not use WRMSR to set IA32_SPEC_CTRL.IBRS after every transition to a more privileged predictor mode. Software can isolate predictor modes effectively simply by setting the bit once. Software need not disable enhanced IBRS prior to entering a sleep state such as MWAIT or HLT." If Enhanced IBRS is supported by the processor then use it as the preferred spectre v2 mitigation mechanism instead of Retpoline. Intel's Retpoline white paper [2] states: "Retpoline is known to be an effective branch target injection (Spectre variant 2) mitigation on Intel processors belonging to family 6 (enumerated by the CPUID instruction) that do not have support for enhanced IBRS. On processors that support enhanced IBRS, it should be used for mitigation instead of retpoline." The reason why Enhanced IBRS is the recommended mitigation on processors which support it is that these processors also support CET which provides a defense against ROP attacks. Retpoline is very similar to ROP techniques and might trigger false positives in the CET defense. If Enhanced IBRS is selected as the mitigation technique for spectre v2, the IBRS bit in SPEC_CTRL MSR is set once at boot time and never cleared. Kernel also has to make sure that IBRS bit remains set after VMEXIT because the guest might have cleared the bit. This is already covered by the existing x86_spec_ctrl_set_guest() and x86_spec_ctrl_restore_host() speculation control functions. Enhanced IBRS still requires IBPB for full mitigation.

[PATCH -fixes] drm/i915: Fix hpd handling for pins with two encoders

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> In my haste to remove irq_port[] I accidentally changed the way we deal with hpd pins that are shared by multiple encoders (DP and HDMI for pre-DDI platforms). Previously we would only handle such pins via ->hpd_pulse(), but now we queue up the hotplug work for the HDMI encoder directly. Worse yet, we now count each hpd twice and this increment the hpd storm count twice as fast. This can lead to spurious storms being detected. Go back to the old way of doing things, ie. delegate to ->hpd_pulse() for any pin which has an encoder with that hook implemented. I don't really like the idea of adding irq_port[] back so let's loop through the encoders first to check if we have an encoder with ->hpd_pulse() for the pin, and then go through all the pins and decided on the correct course of action based on the earlier findings. I have occasionally toyed with the idea of unifying the pre-DDI HDMI and DP encoders into a single encoder as well. Besides the hotplug processing it would have the other benefit of preventing userspace from trying to enable both encoders at the same time. That is simply illegal as they share the same clock/data pins. We have some testcases that will attempt that and thus fail on many older machines.

[PATCH 1/2] drm/vc4: Fix memory leak during gpu reset.

by Maarten Lankhorst

__drm_atomic_helper_crtc_destroy_state does not free memory, it only cleans it up. Fix this by calling the functions own destroy function.

[PATCH AUTOSEL 4.4 01/32] locking/lockdep: Fix debug_locks off performance problem

by Sasha Levin

From: Waiman Long <longman(a)redhat.com> [ Upstream commit 9506a7425b094d2f1d9c877ed5a78f416669269b ] It was found that when debug_locks was turned off because of a problem found by the lockdep code, the system performance could drop quite significantly when the lock_stat code was also configured into the kernel. For instance, parallel kernel build time on a 4-socket x86-64 server nearly doubled. Further analysis into the cause of the slowdown traced back to the frequent call to debug_locks_off() from the __lock_acquired() function probably due to some inconsistent lockdep states with debug_locks off. The debug_locks_off() function did an unconditional atomic xchg to write a 0 value into debug_locks which had already been set to 0. This led to severe cacheline contention in the cacheline that held debug_locks. As debug_locks is being referenced in quite a few different places in the kernel, this greatly slow down the system performance. To prevent that trashing of debug_locks cacheline, lock_acquired() and lock_contended() now checks the state of debug_locks before proceeding. The debug_locks_off() function is also modified to check debug_locks before calling __debug_locks_off().

[PATCH 20/20] can: flexcan: use can_rx_offload_queue_sorted() for flexcan_irq_bus_*()

by Marc Kleine-Budde

[PATCH 16/20] can: dev: __can_get_echo_skb(): print error message, if trying to echo non existing skb

by Marc Kleine-Budde

Prior to echoing a successfully transmitted CAN frame (by calling can_get_echo_skb()), CAN drivers have to put the CAN frame (by calling can_put_echo_skb() in the transmit function). These put and get function take an index as parameter, which is used to identify the CAN frame. A driver calling can_get_echo_skb() with a index not pointing to a skb is a BUG, so add an appropriate error message.

[PATCH 12/20] can: flexcan: remove not needed struct flexcan_priv::tx_mb and struct flexcan_priv::tx_mb_idx

by Marc Kleine-Budde

The previous patch changes the TX path to always use the last mailbox regardless of the used offload scheme (rx-fifo or timestamp based). This means members "tx_mb" and "tx_mb_idx" of the struct flexcan_priv don't depend on the offload scheme, so replace them by compile time constants.
