[PATCH 1/2] Drivers: hv: vmbus: Use get/put_cpu() in vmbus_connect()

by kys＠linuxonhyperv.com

From: Dexuan Cui <decui(a)microsoft.com> With CONFIG_DEBUG_PREEMPT=y, I always see this warning: BUG: using smp_processor_id() in preemptible [00000000] Fix the false warning by using get/put_cpu(). Here vmbus_connect() sends a message to the host and waits for the host's response. The host will deliver the response message and an interrupt on CPU msg->target_vcpu, and later the interrupt handler will wake up vmbus_connect(). vmbus_connect() doesn't really have to run on the same cpu as CPU msg->target_vcpu, so it's safe to call put_cpu() just here.

[PATCH] dm-mpath: Fix setup_scsi_dh()

by Bart Van Assche

This patch fixes two bugs that got introduced recently in setup_scsi_dh(): - Avoid that a memory leak occurs if attached_handler_name is not assigned to m->hw_handler_name. - Avoid that m->hw_handler_name becomes a dangling pointer if the RETAIN_ATTACHED_HW_HANDLER flag is set and scsi_dh_attach() returns -EBUSY.

[PATCH] Revert "ubifs: xattr: Don't operate on deleted inodes"

by Richard Weinberger

This reverts commit 11a6fc3dc743e22fb50f2196ec55bee5140d3c52. UBIFS wants to assert that xattr operations are only issued on files with positive link count. The said patch made this operations return -ENOENT for unlinked files such that the asserts will no longer trigger. This was wrong since xattr operations are perfectly fine on unlinked files. Instead the assertions need to be fixed/removed.

[PATCH RESEND] tpm: Restore functionality to xen vtpm driver.

by Boris Ostrovsky

From: "Dr. Greg Wettstein" <greg(a)wind.enjellic.com> Functionality of the xen-tpmfront driver was lost secondary to the introduction of xenbus multi-page support in commit ccc9d90a9a8b ("xenbus_client: Extend interface to support multi-page ring"). In this commit a pointer to the shared page address was being passed to the xenbus_grant_ring() function rather then the address of the shared page itself. This resulted in a situation where the driver would attach to the vtpm-stubdom but any attempt to send a command to the stub domain would timeout. A diagnostic finding for this regression is the following error message being generated when the xen-tpmfront driver probes for a device: <3>vtpm vtpm-0: tpm_transmit: tpm_send: error -62 <3>vtpm vtpm-0: A TPM error (-62) occurred attempting to determine the timeouts This fix is relevant to all kernels from 4.1 forward which is the release in which multi-page xenbus support was introduced. Daniel De Graaf formulated the fix by code inspection after the regression point was located.

[PATCH for-4.9.y 00/14] Few upstream fixes from OnePlus6's kernel tree

by Amit Pundir

Hi Greg, For your consideration, few upstream fixes picked up from Qcom's android-4.9 BSP tree for OnePlus 6 device. Cherry-picked and build tested for ARCH=x86_64/mips on v4.9.124. Few patches are applicable for 4.4.y and 3.18.y as well and explicitly marked so respectively. Regards, Amit Pundir Daniel Micay (1): staging/rts5208: Fix read overflow in memcpy Jason A.
