2016-09-01ovl: handle umask and posix_acl_default correctly on creationMiklos Szeredi
Setting MS_POSIXACL in sb->s_flags has the side effect of passing mode to create functions without masking against umask. Another problem when creating over a whiteout is that the default posix acl is not inherited from the parent dir (because the real parent dir at the time of creation is the work directory). Fix these problems by: a) If upper fs does not have MS_POSIXACL, then mask mode with umask. b) If creating over a whiteout, call posix_acl_create() to get the inherited acls. After creation (but before moving to the final destination) set these acls on the created file. posix_acl_create() also updates the file creation mode as appropriate.

2016-08-31binfmt_elf: switch to new creds when switching to new mmLinus Torvalds
We used to delay switching to the new credentials until after we had mapped the executable (and possible elf interpreter). That was kind of odd to begin with, since the new executable will actually then _run_ with the new creds, but whatever. The bigger problem was that we also want to make sure that we turn off prof events and tracing before we start mapping the new executable state. So while this is a cleanup, it's also a fix for a possible information leak.

2016-08-31drivers: char: mem: Check {read,write}_kmem() addressesRobin Murphy
Arriving at read_kmem() with an offset representing a bogus kernel address (e.g. 0 from a simple "cat /dev/kmem") leads to copy_to_user faulting on the kernel-side read. x86_64 happens to get away with this since the optimised implementation uses "rep movs*", thus the user write (which is allowed to fault) and the kernel read are the same instruction, the kernel-side fault falls into the user-side fixup handler and the chain of events which transpires ends up returning an error as one might expect, even if it's an inappropriate -EFAULT. On other architectures, though, the read is not covered by the fixup entry for the write, and we get a big scary "Unable to hande kernel paging request..." dump. The more typical use-case of mmap_kmem() has always (within living memory at least) returned -EIO for addresses which don't satisfy pfn_valid(), so let's make that consistent across {read,write}_kem() too.

2016-08-31sysfs: correctly handle read offset on PREALLOC attrsKonstantin Khlebnikov
Attributes declared with __ATTR_PREALLOC use sysfs_kf_read() which returns zero bytes for non-zero offset. This breaks script checkarray in mdadm tool in debian where /bin/sh is 'dash' because its builtin 'read' reads only one byte at a time. Script gets 'i' instead of 'idle' when reads current action from /sys/block/$dev/md/sync_action and as a result does nothing.

2016-08-31kernfs: don't depend on d_find_any_alias() when generating notificationsTejun Heo
kernfs_notify_workfn() sends out file modified events for the scheduled kernfs_nodes. Because the modifications aren't from userland, it doesn't have the matching file struct at hand and can't use fsnotify_modify(). Instead, it looked up the inode and then used d_find_any_alias() to find the dentry and used fsnotify_parent() and fsnotify() directly to generate notifications. The assumption was that the relevant dentries would have been pinned if there are listeners, which isn't true as inotify doesn't pin dentries at all and watching the parent doesn't pin the child dentries even for dnotify. This led to, for example, inotify watchers not getting notifications if the system is under memory pressure and the matching dentries got reclaimed. It can also be triggered through /proc/sys/vm/drop_caches or a remount attempt which involves shrinking dcache. fsnotify_parent() only uses the dentry to access the parent inode, which kernfs can do easily. Update kernfs_notify_workfn() so that it uses fsnotify() directly for both the parent and target inodes without going through d_find_any_alias(). While at it, supply the target file name to fsnotify() from kernfs_node->name.

The mwave driver has its own macros for the BOOLEAN type and the TRUE/FALSE values. This is redundant because the kernel already has bool/true/false, and it clashes with the ACPI headers that also define these types.

2016-08-31thunderbolt: Fix resume quirk for Falcon Ridge 4C.Andreas Noever
The quirk 'quirk_apple_wait_for_thunderbolt' did not fire on Falcon Ridge 4C controllers with subdevice/subvendor set to zero. This lead to lost pci devices on system resume. Older thunderbolt controllers (pre Falcon Ridge) used the same device id for bridges and for the controller. On Apple hardware the subvendor- & subdevice-ids were set for the controller, but not for bridges. So that is what was used to differentiate between the two. Starting with Falcon Ridge bridges and controllers received different device ids. Additionally on some MacBookPro models (but not all) the subvendor/subdevice was zeroed. Starting with a42fb351c (thunderbolt: Allow loading of module on recent Apple MacBooks with thunderbolt 2 controller) the thunderbolt driver binds to all Falcon Ridge 4C controllers (irregardless of subvendor/subdevice). The corresponding quirk was not updated. This commit changes the quirk to check the device class instead of its subvendor-/subdeviceids. This works for all generations of Thunderbolt controllers.

The Kconfig currently controlling compilation of this code is: drivers/vme/Kconfig:menuconfig VME_BUS drivers/vme/Kconfig: bool "VME bridge support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We replace module.h and moduleparam.h (unused) with init.h and also export.h ; the latter since this file does export some syms. Since this is a struct bus_type and not a platform_driver, we don't have any ".suppress_bind_attrs" to be concerned about when we drop the ".remove" code from this file.

2016-08-31vme: change LM callback argument to void pointerAaron Sierra
Make the location monitor callback function prototype more useful by changing the argument from an integer to a void pointer. All VME bridge drivers were simply passing the location monitor index (e.g. 0-3) as the argument to these callbacks. It is much more useful to pass back a pointer to data that the callback-registering driver cares about. There appear to be no in-kernel callers of vme_lm_attach (or vme_lme_request for that matter), so this change only affects the VME subsystem and bridge drivers.

Use memdup_user to duplicate a memory region from user-space to kernel-space, instead of open coding using kmalloc & copy_from_user. Signed-off-by: Muhammad Falak R Wani <falakreyaz@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-08-31mcb: remove sub-device handling codeJohannes Thumshirn
The MEN Chameleon specification states that a chameleon FPGA can include a bridge descriptor, which then opens up a new bus behind this bridge. MCB included subdevice handling code in the core, but no support for bus descriptors in the parser, due to a lack of hardware access. As this is technically dead code, but it gets executed on a device add, I've decided to remove it.

2016-08-31mcb: Introduce type safety for to_mcb_*Johannes Thumshirn
The to_mcb_{bus,device,driver}() macros lacked type safety, so convert them to inline functions to enforce compile time type checking. Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-08-31mcb: Added bar descriptor support for non PCI bus MCB carrierAndreas Werner
Added support for the bar descriptor. This type is used for FPGAs connect to the LPC or to a non PCI bus. The Bar descriptor could have a maximum of 6 BARs. Each of the devices within the FPGA could be mapped to a different BAR. The BAR descriptor is comparable to the PCI header.

2016-08-31mcb: Added support for LPC or non PCI based MCB carrierAndreas Werner
Add support for MCB bases FPGAs connected to the LPC or non PCI Bus. This driver currently supports the SC24 board. The FPGA is connected to the LPC bus and is identified using the BIOS DMI string.
