2016-07-12cxlflash: Shutdown notify support for CXL Flash cardsUma Krishnan
Some CXL Flash cards need notification of device shutdown in order to flush pending I/Os. A PCI notification hook for shutdown has been added where the driver notifies the card and returns. When the device is removed in the PCI remove path, notification code will wait for shutdown processing to complete. Signed-off-by: Uma Krishnan <ukrishn@linux.vnet.ibm.com> Acked-by: Manoj N.

2016-07-12cxlflash: Add device dependent flagsUma Krishnan
Device dependent flags are needed to support functions that are specific to a particular device. One such case is - some CXL Flash cards need to be notified of device shutdown. For other CXL devices, this feature does not prove to be useful yet. Such distinct features need to be identified in the driver to bypass or invoke specific functionality. In this patch, a member 'flags' has been added to device dependent values. These flags will be used and expanded in the future to support various device specific functions.

2016-07-12cxlflash: Fix to drain operations from previous resetManoj N. Kumar
While running 'sg_reset -H' in a loop with a user-space application active, hit the following exception: cpu 0x2: Vector: 300 (Data Access) pc: : afu_attach+0x50/0x240 [cxlflash] lr: : cxlflash_afu_recover+0x3dc/0x7d0 [cxlflash] pid = 20365, comm = run_block_fvt Linux version 4.5.0-491-26f710d+ cxlflash_afu_recover+0x3dc/0x7d0 [cxlflash] cxlflash_ioctl+0x5a8/0x6f0 [cxlflash] scsi_ioctl+0x3b0/0x4c0 sd_ioctl+0x110/0x190 blkdev_ioctl+0x28c/0xc20 block_ioctl+0xa4/0xd0 do_vfs_ioctl+0xd8/0x8c0 SyS_ioctl+0xd4/0xf0 system_call+0x38/0xb4 The problem here is that the problem space area is unmapped while the application issues the DK_CXLFLASH_RECOVER_AFU ioctl. This is the order I observe: proc1 proc2 1) sg_reset 2) ioctl(DK_CXLFLASH_RECOVER_AFU) 3) sg_reset again causing a PSA unmap 4) continues RECOVER_AFU processing The resolution to this problem is to have the reset handler drain all outstanding user space initiated ioctls before proceeding. It is safe to drain after the state has been changed to STATE_RESET. Also since drain_ioctls() was static, it had to be moved up a bit to be before cxlflash_eh_host_reset_handler().

2016-07-12scsi_debug: fix sleep in invalid contextDouglas Gilbert
In this post: http://www.spinics.net/lists/linux-scsi/msg97124.html the author shows some kernel infrastructure complaining about a sleep in an invalid context. Remove offending call to vmalloc(). Instead of using kzalloc() which reviewers didn't like, use a bucket system (64 bytes on the stack) and potentially multiple calls to sg_pcopy_from_buffer() to construct the 'data-in' buffer for the SCSI REPORT LUNS command.

2016-07-12libfc: Update rport reference countingHannes Reinecke
Originally libfc would just be initializing the refcount to '1', and using the disc_mutex to synchronize if and when the final put should be happening. This has a race condition as the mutex might be delayed, causing other threads to access an invalid structure. This patch updates the rport reference counting to increase the reference every time 'rport_lookup' is called, and decreases the reference correspondingly. This removes the need to hold 'disc_mutex' when removing the structure, and avoids the above race condition.

In _scsih_sas_host_add, the number of HBA phys are determined and then later used to allocate an array of struct _sas_phy's. If the routine sets ioc->sas_hba.num_phys, but then fails to allocate the ioc->sas_hba.phy array (by kcalloc error or other intermediate error/exit path), ioc->sas_hba is left in a dangerous state: all readers of ioc->sas_hba.phy[] do so by indexing it from 0..ioc->sas_hba.num_phys without checking that the space was ever allocated.

The well-spotted fallocate undo fix is good in most cases, but not when fallocate failed on the very first page. index 0 then passes lend -1 to shmem_undo_range(), and that has two bad effects: (a) that it will undo every fallocation throughout the file, unrestricted by the current range; but more importantly (b) it can cause the undo to hang, because lend -1 is treated as truncation, which makes it keep on retrying until every page has gone, but those already fully instantiated will never go away.

Specifically, we now enforce USER_DS on taking exceptions whilst in the kernel, which avoids leaking kernel data to userspace through things like perf. The other patch is an update to a workaround for a hardware erratum on some Cavium SoCs.

2016-07-08ecryptfs: don't allow mmap when the lower fs doesn't support itJeff Mahoney
There are legitimate reasons to disallow mmap on certain files, notably in sysfs or procfs. We shouldn't emulate mmap support on file systems that don't offer support natively.

2016-07-08xen/acpi: allow xen-acpi-processor driver to load on Xen 4.7Jan Beulich
As of Xen 4.7 PV CPUID doesn't expose either of CPUID[1].ECX[7] and CPUID[0x80000007].EDX[7] anymore, causing the driver to fail to load on both Intel and AMD systems. Doing any kind of hardware capability checks in the driver as a prerequisite was wrong anyway: With the hypervisor being in charge, all such checking should be done by it. If ACPI data gets uploaded despite some missing capability, the hypervisor is free to ignore part or all of that data. Ditch the entire check_prereq() function, and do the only valid check (xen_initial_domain()) in the caller in its place.
