2020-02-17sctp: move the format error check out of __sctp_sf_do_9_1_abortXin Long
When T2 timer is to be stopped, the asoc should also be deleted, otherwise, there will be no chance to call sctp_association_free and the asoc could last in memory forever. However, in sctp_sf_shutdown_sent_abort(), after adding the cmd SCTP_CMD_TIMER_STOP for T2 timer, it may return error due to the format error from __sctp_sf_do_9_1_abort() and miss adding SCTP_CMD_ASSOC_FAILED where the asoc will be deleted. This patch is to fix it by moving the format error check out of __sctp_sf_do_9_1_abort(), and do it before adding the cmd SCTP_CMD_TIMER_STOP for T2 timer. Thanks Hangbin for reporting this issue by the fuzz testing. v1->v2: - improve the comment in the code as Marcelo's suggestion.

2020-02-17net: sched: correct flower port blockingJason Baron
tc flower rules that are based on src or dst port blocking are sometimes ineffective due to uninitialized stack data. __skb_flow_dissect() extracts ports from the skb for tc flower to match against. However, the port dissection is not done when when the FLOW_DIS_IS_FRAGMENT bit is set in key_control->flags. All callers of __skb_flow_dissect(), zero-out the key_control field except for fl_classify() as used by the flower classifier. Thus, the FLOW_DIS_IS_FRAGMENT may be set on entry to __skb_flow_dissect(), since key_control is allocated on the stack and may not be initialized. Since key_basic and key_control are present for all flow keys, let's make sure they are initialized.

2020-02-17net: mscc: fix in frame extractionHoratiu Vultur
Each extracted frame on Ocelot has an IFH. The frame and IFH are extracted by reading chuncks of 4 bytes from a register. In case the IFH and frames were read corretly it would try to read the next frame. In case there are no more frames in the queue, it checks if there were any previous errors and in that case clear the queue. But this check will always succeed also when there are no errors. Because when extracting the IFH the error is checked against 4(number of bytes read) and then the error is set only if the extraction of the frame failed. So in a happy case where there are no errors the err variable is still 4. So it could be a case where after the check that there are no more frames in the queue, a frame will arrive in the queue but because the error is not reseted, it would try to flush the queue. So the frame will be lost. The fix consist in resetting the error after reading the IFH.

2020-02-17drm/i915/gt: Prevent queuing retire workers on the virtual engineChris Wilson
Virtual engines are fleeting. They carry a reference count and may be freed when their last request is retired. This makes them unsuitable for the task of housing engine->retire.work so assert that it is not used. Tvrtko tracked down an instance where we did indeed violate this rule. In virtual_submit_request, we flush a completed request directly with __i915_request_submit and this causes us to queue that request on the veng's breadcrumb list and signal it. Leading us down a path where we should not attach the retire.

We lack full state readout of DSC config, which may lead to DSC enable using a config that's all zeros, failing spectacularly. Force full modeset and thus compute config at probe to get a sane state, until we implement DSC state readout. Any fastset that did appear to work with DSC at probe, worked by coincidence.

2020-02-17tpm: Initialize crypto_id of allocated_banks to HASH_ALGO__LASTRoberto Sassu
chip->allocated_banks, an array of tpm_bank_info structures, contains the list of TPM algorithm IDs of allocated PCR banks. It also contains the corresponding ID of the crypto subsystem, so that users of the TPM driver can calculate a digest for a PCR extend operation. However, if there is no mapping between TPM algorithm ID and crypto ID, the crypto_id field of tpm_bank_info remains set to zero (the array is allocated and initialized with kcalloc() in tpm2_get_pcr_allocation()). Zero should not be used as value for unknown mappings, as it is a valid crypto ID (HASH_ALGO_MD4). Thus, initialize crypto_id to HASH_ALGO__LAST.

2020-02-17drm/i915/gem: Require per-engine reset support for non-persistent contextsChris Wilson
To enable non-persistent contexts, we require a means of cancelling any inflight work from that context. This is first done "gracefully" by using preemption to kick the active context off the engine, and then forcefully by resetting the engine if it is active. If we are unable to reset the engine to remove hostile userspace, we should not allow userspace to opt into using non-persistent contexts. If the per-engine reset fails, we still do a full GPU reset, but that is rare and usually indicative of much deeper issues. The damage is already done. However, the goal of the interface to allow long running compute jobs without causing collateral damage elsewhere, and if we are unable to support that we should make that known by not providing the interface (and falsely pretending we can).

2020-02-17btrfs: don't set path->leave_spinning for truncateJosef Bacik
The only time we actually leave the path spinning is if we're truncating a small amount and don't actually free an extent, which is not a common occurrence. We have to set the path blocking in order to add the delayed ref anyway, so the first extent we find we set the path to blocking and stay blocking for the duration of the operation. With the upcoming file extent map stuff there will be another case that we have to have the path blocking, so just swap to blocking always. Note: this patch also fixes a warning after 28553fa992cb ("Btrfs: fix race between shrinking truncate and fiemap") got merged that inserts extent locks around truncation so the path must not leave spinning locks after btrfs_search_slot.

2020-02-17kvm: arm/arm64: Fold VHE entry/exit work into kvm_vcpu_run_vhe()Mark Rutland
With VHE, running a vCPU always requires the sequence: 1. kvm_arm_vhe_guest_enter(); 2. kvm_vcpu_run_vhe(); 3. kvm_arm_vhe_guest_exit() ... and as we invoke this from the shared arm/arm64 KVM code, 32-bit arm has to provide stubs for all three functions. To simplify the common code, and make it easier to make further modifications to the arm64-specific portions in the near future, let's fold kvm_arm_vhe_guest_enter() and kvm_arm_vhe_guest_exit() into kvm_vcpu_run_vhe(). The 32-bit stubs for kvm_arm_vhe_guest_enter() and kvm_arm_vhe_guest_exit() are removed, as they are no longer used. The 32-bit stub for kvm_vcpu_run_vhe() is left as-is.

2020-02-17watchdog: da9062: do not ping the hw during stop()Marco Felsch
The da9062 hw has a minimum ping cool down phase of at least 200ms. The driver takes that into account by setting the min_hw_heartbeat_ms to 300ms and the core guarantees that the hw limit is observed for the ping() calls. But the core can't guarantee the required minimum ping cool down phase if a stop() command is send immediately after the ping() command. So it is not allowed to ping the watchdog within the stop() command as the driver does. Remove the ping can be done without doubts because the watchdog gets disabled anyway and a (re)start resets the watchdog counter too.

2020-02-17EDAC/mc: Remove enable_per_layer_report function argumentRobert Richter
Many functions carry the enable_per_layer_report argument. This is a bool value indicating the error information contains some location data where the error occurred. This can easily being determined by checking the pos[] array for values. Negative values indicate there is no location available. So if the top layer is negative, the error location is unknown. Just check if the top layer is negative and remove enable_per_layer_report as function argument and also from struct edac_raw_error_desc.

2020-02-17EDAC/mc: Report "unknown memory" on too many DIMM labels foundRobert Richter
There is a limitation to report only EDAC_MAX_LABELS in e->label of the error descriptor. This is to prevent a potential string overflow. The current implementation falls back to "any memory" in this case and also stops all further processing to find a unique row and channel of the possible error location. Reporting "any memory" is wrong as the memory controller reported an error location for one of the layers. Instead, report "unknown memory" and also do not break early in the loop to further check row and channel for uniqueness.
