We aren't checking to see if the in-inode extended attribute is corrupted before we try to expand the inode's extra isize fields. This can lead to potential crashes caused by the BUG_ON() check in ext4_xattr_shift_entries(). Signed-off-by:

Pull i2c updates from Wolfram Sang: "Mostly usual driver updates and improvements. The changelog should give an idea. Standing out is the i2c-qup driver with lots of new capabilities and we also have now an i2c-demuxer. I'd especially like to welcome Peter Rosin as the i2c-mux maintainer. He has an interesting series for muxes in the queue and agreed to look after this part of the subsystem. Thank you, Peter, and welcome again! The octeon changes were applied pretty recently before the merge window. I am aware. They are the first (and relatively simple) patches of a larger overhaul to this driver. In case something goes wrong with them, they are easy to fix (or revert). The advantage I see is that they are out of the way, and I can concentrate on the next block of patches. I really would like to apply the overhaul in smaller batches to avoid regressions.

This patch fixes an active I/O shutdown bug for fabric drivers using target_wait_for_sess_cmds(), where se_cmd descriptor shutdown would result in hung tasks waiting indefinitely for se_cmd->cmd_wait_comp to complete(). To address this bug, drop the incorrect list_del_init() usage in target_wait_for_sess_cmds() and always complete() during se_cmd target_release_cmd_kref() put, in order to let caller invoke the final fabric release callback into se_cmd->se_tfo->release_cmd() code.

Pull MMC updates from Ulf Hansson: "MMC core: - Fix ABI regression of MMC BLK ioctl - Remove the unused MMC_DATA_STREAM flag - Enable asynchronous system PM for the host device - Minor fixes and clean-ups SDHCI host: Throughout the years, the numbers of SDHCI variants have increased and so has also the numbers of SDHCI callbacks/quirks. The purpose of these callbacks/quirks were to enable SDHCI to deal with variant specific requirements, but unfortunate this method didn't scale. Instead we have ended up with a mess. Not only did the code become suboptimal but also highly fragile. Lately many discussions of how to move forward with SDHCI has taken place at the MMC mailing list. Step by step, we aim to turn SDHCI's common code into a set of library functions. This will enable for optimizations and allow some of the existing callbacks and quirks to be removed, which also should help to make the code less fragile. Therefore I am also really pleased to announce that Adrian Hunter (Intel) has volunteered to step in as the maintainer for SDHCI. Future wise, I hope the community around SDHCI will continue to grow and that this release cycle can be the starting point of moving SDHCI into a better shape. As a matter of fact, already in this cycle the re-factoring has begun, but of course there are also fixes and new features included.

Pull xfs updates from Dave Chinner: "There's quite a lot in this request, and there's some cross-over with ext4, dax and quota code due to the nature of the changes being made. As for the rest of the XFS changes, there are lots of little things all over the place, which add up to a lot of changes in the end. The major changes are that we've reduced the size of the struct xfs_inode by ~100 bytes (gives an inode cache footprint reduction of >10%), the writepage code now only does a single set of mapping tree lockups so uses less CPU, delayed allocation reservations won't overrun under random write loads anymore, and we added compile time verification for on-disk structure sizes so we find out when a commit or platform/compiler change breaks the on disk structure as early as possible. Change summary: - error propagation for direct IO failures fixes for both XFS and ext4 - new quota interfaces and XFS implementation for iterating all the quota IDs in the filesystem - locking fixes for real-time device extent allocation - reduction of duplicate information in the xfs and vfs inode, saving roughly 100 bytes of memory per cached inode. - buffer flag cleanup - rework of the writepage code to use the generic write clustering mechanisms - several fixes for inode flag based DAX enablement - rework of remount option parsing - compile time verification of on-disk format structure sizes - delayed allocation reservation overrun fixes - lots of little error handling fixes - small memory leak fixes - enable xfsaild freezing again" * tag 'xfs-for-linus-4.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (66 commits) xfs: always set rvalp in xfs_dir2_node_trim_free xfs: ensure committed is initialized in xfs_trans_roll xfs: borrow indirect blocks from freed extent when available xfs: refactor delalloc indlen reservation split into helper xfs: update freeblocks counter after extent deletion xfs: debug mode forced buffered write failure xfs: remove impossible condition xfs: check sizes of XFS on-disk structures at compile time xfs: ioends require logically contiguous file offsets xfs: use named array initializers for log item dumping xfs: fix computation of inode btree maxlevels xfs: reinitialise per-AG structures if geometry changes during recovery xfs: remove xfs_trans_get_block_res xfs: fix up inode32/64 (re)mount handling xfs: fix format specifier , should be %llx and not %llu xfs: sanitize remount options xfs: convert mount option parsing to tokens xfs: fix two memory leaks in xfs_attr_list.c error paths xfs: XFS_DIFLAG2_DAX limited by PAGE_SIZE xfs: dynamically switch modes when XFS_DIFLAG2_DAX is set/cleared ...

The 'is_merge' is an historical naming from when only a single lower layer could exist. With the introduction of multiple lower layers the meaning of this flag was changed to mean only the "lowest layer" (while all lower layers were being merged). So now 'is_merge' is inaccurate and hence renaming to 'is_lowest' Signed-off-by:

In some instances xfs has been created with ftype=0 and there if a file on lower fs is removed, overlay leaves a whiteout in upper fs but that whiteout does not get filtered out and is visible to overlayfs users. And reason it does not get filtered out because upper filesystem does not report file type of whiteout as DT_CHR during iterate_dir(). So it seems to be a requirement that upper filesystem support d_type for overlayfs to work properly. Do this check during mount and fail if d_type is not supported. Suggested-by:

Print a warning when overlayfs copies up a file if the process that triggered the copy up has a R/O fd open to the lower file being copied up. This can help catch applications that do things like the following: fd1 = open("foo", O_RDONLY); fd2 = open("foo", O_RDWR); where they expect fd1 and fd2 to refer to the same file - which will no longer be the case post-copy up. With this patch, the following commands: bash 5</mnt/a/foo128 6<>/mnt/a/foo128 assuming /mnt/a/foo128 to be an un-copied up file on an overlay will produce the following warning in the kernel log: overlayfs: Copying up foo129, but open R/O on fd 5 which will cease to be coherent [pid=3818 bash] This is enabled by setting: /sys/module/overlay/parameters/check_copy_up to 1. The warnings are ratelimited and are also limited to one warning per file - assuming the copy up completes in each case. Signed-off-by:

This patch hides error about missing lowerdir if MS_SILENT is set. We use mount(NULL, "/", "overlay", MS_SILENT, NULL) for testing support of overlayfs: syscall returns -ENODEV if it's not supported. Otherwise kernel automatically loads module and returns -EINVAL because lowerdir is missing. Signed-off-by:

Unlink and rename in overlayfs checked the upper dentry for staleness by verifying upper->d_parent against upperdir. However the dentry can go stale also by being unhashed, for example. Expand the verification to actually look up the name again (under parent lock) and check if it matches the upper dentry. This matches what the VFS does before passing the dentry to filesytem's unlink/rename methods, which excludes any inconsistency caused by overlayfs. Signed-off-by:

i915 get_eld ops may return an error when no encoder is connected, and currently we regard the error as fatal and skip the whole ELD handling. This ended up with the missing ELD update at unplugging. This patch fixes the issue by treating the error as the unplugged state, instead of skipping the rest. Reported-by:

The Kconfig currently controlling compilation of this code is: arch/x86/xen/Kconfig:config XEN_PVHVM arch/x86/xen/Kconfig: def_bool y ...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. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. In removing "module" from the init fcn name, we observe a namespace collision with the probe function, so we use "probe" in the name of the probe function, and "init" in the registration fcn, as per standard convention, as suggested by Stefano.

Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. However one could argue that fs_initcall() might make more sense here. This change means that the one line function xen_properties_destroy() has only one user left, and since that is inside an #ifdef, we just manually inline it there vs. adding more ifdeffery around the function to avoid compile warnings about "defined but not used". In order to be consistent we also manually inline the other _destroy functions that are also just one line sysfs functions calls with only one call site remaing, even though they wouldn't need #ifdeffery.

Code that uses no modular facilities whatsoever should not be sourcing module.h at all, since that header drags in a bunch of other headers with it. Similarly, code that is not explicitly using modular facilities like module_init() but only is declaring module_param setup variables should be using moduleparam.h and not the larger module.h file for that. In making this change, we also uncover an implicit use of BUG() in inline fcns within arch/arm/include/asm/xen/hypercall.h so we explicitly source <linux/bug.h> for that file now. Signed-off-by:

Commit c40a3d38 (Btrfs: Compute and look up csums based on sectorsized blocks) changes around how we walk the bios while looking up crcs. There's an inner loop that is jumping to the next bvec based on sectors and before it derefs the next bvec, it needs to make sure we're still in the bio. In this case, the outer loop would have decided to stop moving forward too, and the bvec deref is never actually used for anything. But CONFIG_DEBUG_PAGEALLOC catches it because we're outside our bio. Signed-off-by:

Commit c6b90653 ("drivers/perf: arm_pmu: make info messages more verbose") breaks booting on systems where the PMU is probed without devicetree (e.g by inspecting the MIDR of the current CPU). In this case, pdev->dev.of_node is NULL and we shouldn't try to access its ->fullname field when printing probe error messages. This patch fixes the probing code to use of_node_full_name, which safely handles NULL nodes and removes the "Error %i" part of the string, since it's not terribly useful. Reported-by:
