This finally merges the long-pending orangefs filesystem, which has been much cleaned up with input from Al Viro over the last six months. From the documentation file: "OrangeFS is an LGPL userspace scale-out parallel storage system. It is ideal for large storage problems faced by HPC, BigData, Streaming Video, Genomics, Bioinformatics. Orangefs, originally called PVFS, was first developed in 1993 by Walt Ligon and Eric Blumer as a parallel file system for Parallel Virtual Machine (PVM) as part of a NASA grant to study the I/O patterns of parallel programs. Orangefs features include: - Distributes file data among multiple file servers - Supports simultaneous access by multiple clients - Stores file data and metadata on servers using local file system and access methods - Userspace implementation is easy to install and maintain - Direct MPI support - Stateless" see Documentation/filesystems/orangefs.txt for more in-depth details. * tag 'ofs-pull-tag-1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux: (174 commits) orangefs: fix orangefs_superblock locking orangefs: fix do_readv_writev() handling of error halfway through orangefs: have ->kill_sb() evict the VFS side of things first orangefs: sanitize ->llseek() orangefs-bufmap.h: trim unused junk orangefs: saner calling conventions for getting a slot orangefs_copy_{to,from}_bufmap(): don't pass bufmap pointer orangefs: get rid of readdir_handle_s ornagefs: ensure that truncate has an up to date inode size orangefs: move code which sets i_link to orangefs_inode_getattr orangefs: remove needless wrapper around GFP_KERNEL orangefs: remove wrapper around mutex_lock(&inode->i_mutex) orangefs: refactor inode type or link_target change detection orangefs: use new getattr for revalidate and remove old getattr orangefs: use new getattr in inode getattr and permission orangefs: use new orangefs_inode_getattr to get size in write and llseek orangefs: use new orangefs_inode_getattr to create new inodes orangefs: rename orangefs_inode_getattr to orangefs_inode_old_getattr orangefs: remove inode->i_lock wrapper orangefs: put register_chrdev immediately before register_filesystem ...

This is a monster pull request. I held off on the hfi1 driver updates (the hfi1 driver is intimately tied to the qib driver and the new rdmavt software library that was created to help both of them) in my first pull request. The hfi1/qib/rdmavt update is probably 90% of this pull request. The hfi1 driver is being left in staging so that it can be fixed up in regards to the API that Al and yourself didn't like. Intel has agreed to do the work, but in the meantime, this clears out 300+ patches in the backlog queue and brings my tree and their tree closer to sync. This also includes about 10 patches to the core and a few to mlx5 to create an infrastructure for configuring SRIOV ports on IB devices. That series includes one patch to the net core that we sent to netdev@ and Dave Miller with each of the three revisions to the series. We didn't get any response to the patch, so we took that as implicit approval. Finally, this series includes Intel's new iWARP driver for their x722 cards. It's not nearly the beast as the hfi1 driver. It also has a linux-next merge issue, but that has been resolved and it now passes just fine. Summary: - A few minor core fixups needed for the next patch series - The IB SRIOV series. This has bounced around for several versions. Of note is the fact that the first patch in this series effects the net core. It was directed to netdev and DaveM for each iteration of the series (three versions total). Dave did not object, but did not respond either. I've taken this as permission to move forward with the series. - The new Intel X722 iWARP driver - A huge set of updates to the Intel hfi1 driver. Of particular interest here is that we have left the driver in staging since it still has an API that people object to. Intel is working on a fix, but getting these patches in now helps keep me sane as the upstream and Intel's trees were over 300 patches apart" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (362 commits) IB/ipoib: Allow mcast packets from other VFs IB/mlx5: Implement callbacks for manipulating VFs net/mlx5_core: Implement modify HCA vport command net/mlx5_core: Add VF param when querying vport counter IB/ipoib: Add ndo operations for configuring VFs IB/core: Add interfaces to control VF attributes IB/core: Support accessing SA in virtualized environment IB/core: Add subnet prefix to port info IB/mlx5: Fix decision on using MAD_IFC net/core: Add support for configuring VF GUIDs IB/{core, ulp} Support above 32 possible device capability flags IB/core: Replace setting the zero values in ib_uverbs_ex_query_device net/mlx5_core: Introduce offload arithmetic hardware capabilities net/mlx5_core: Refactor device capability function net/mlx5_core: Fix caching ATOMIC endian mode capability ib_srpt: fix a WARN_ON() message i40iw: Replace the obsolete crypto hash interface with shash IB/hfi1: Add SDMA cache eviction algorithm IB/hfi1: Switch to using the pin query function IB/hfi1: Specify mm when releasing pages ...

This new driver is a software implementation of the InfiniBand verbs and aims to replace the multiple implementations that exist and duplicate each others' code. While the call to actually register the device with the IB core happens in rdma_vt, most of the work is still done in the drivers themselves. This will be changing in a follow on patch this is just laying the groundwork for this infrastructure.

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.

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. Some highlights: - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP - sdhci-acpi: Add support for QCOM controllers - sdhci-pic32: Add new SDHCI variant for PIC32MZDA Other hosts: - atmel-mci: Fix a NULL pointer dereference - mediatek: Add SD write-protect support - mmc_spi: Fix card detect in GPIO case - tmio/sdhi: Add r8a7795 support - tmio/sdhi: Some fixes and clean-ups - dw_mmc: Add HW reset support - dw_mmc: Some fixes and clean-ups - sunxi: Add support for MMC DDR52 mode" * tag 'mmc-v4.6' of git://git.linaro.org/people/ulf.hansson/mmc: (123 commits) mmc: sdhci-of-at91: fix wake-up issue when using runtime pm mmc: sdhci-pci: Do not set DMA mask in enable_dma() mmc: sdhci-acpi: Remove enable_dma() hook mmc: sdhci: Set DMA mask when adding host mmc: block: fix ABI regression of mmc_blk_ioctl mmc: atmel-mci: Check pdata for NULL before dereferencing it at DMA config mmc: core: remove redundant memset of sdio_read_cccr mmc: core: remove redundant memset of mmc_decode_cid mmc: of_mmc_spi: fix unused warning mmc: sdhci-of-arasan: add phy support for sdhci-of-arasan mmc: sdhci-of-arasan: fix missing sdhci_pltfm_free for err handling mmc: sdhci-of-arasan: remove disable clk_ahb from sdhci_arasan_resume Documentation: bindings: add description of phy for sdhci-of-arasan mmc: sdhci: Fix override of timeout clk wrt max_busy_timeout mmc: mmci: Remove unnecessary header file mmc: sdhci-acpi: add QCOM controllers mmc: tegra: implement memcomp pad calibration mmc: mediatek: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch mmc: mediatek: Change signal voltage error to dev_dbg() mmc: sh_mmcif, tmio: Use ARCH_RENESAS ...

I am very pleased that Adrian Hunter volunteered and accepted the challenge! The SDHCI code is currently in quite poor quality, but we have agreed on a way forward to try to reach a point where the SDHCI core becomes more of a set of library functions. Each SDHCI driver variant can then decide which functions to use and allows it to implement variant specific code, without needing to also change SDHCI core code. In the end we aim to get better optimized and maintainable code. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Adrian Hunter <adrian.hunter@intel.com>

It was written by and is maintained by Josh Poimboeuf. The motivation: there's a category of hard to find kernel bugs, most of them in assembly code (but also occasionally in C code), that degrades the quality of kernel stack dumps/backtraces. These bugs are hard to detect at the source code level. Such bugs result in incorrect/incomplete backtraces most of time - but can also in some rare cases result in crashes or other undefined behavior. The build time correctness checking is done via the new 'objtool' user-space utility that was written for this purpose and which is hosted in the kernel repository in tools/objtool/. The tool's (very simple) UI and source code design is shaped after Git and perf and shares quite a bit of infrastructure with tools/perf (which tooling infrastructure sharing effort got merged via perf and is already upstream). Objtool follows the well-known kernel coding style. Objtool does not try to check .c or .S files, it instead analyzes the resulting .o generated machine code from first principles: it decodes the instruction stream and interprets it. (Right now objtool supports the x86-64 architecture.) From tools/objtool/Documentation/stack-validation.txt: "The kernel CONFIG_STACK_VALIDATION option enables a host tool named objtool which runs at compile time. It has a "check" subcommand which analyzes every .o file and ensures the validity of its stack metadata. It enforces a set of rules on asm code and C inline assembly code so that stack traces can be reliable. Currently it only checks frame pointer usage, but there are plans to add CFI validation for C files and CFI generation for asm files. For each function, it recursively follows all possible code paths and validates the correct frame pointer state at each instruction. It also follows code paths involving special sections, like .altinstructions, __jump_table, and __ex_table, which can add alternative execution paths to a given instruction (or set of instructions). Similarly, it knows how to follow switch statements, for which gcc sometimes uses jump tables." When this new kernel option is enabled (it's disabled by default), the tool, if it finds any suspicious assembly code pattern, outputs warnings in compiler warning format: warning: objtool: rtlwifi_rate_mapping()+0x2e7: frame pointer state mismatch warning: objtool: cik_tiling_mode_table_init()+0x6ce: call without frame pointer save/setup warning: objtool:__schedule()+0x3c0: duplicate frame pointer save warning: objtool:__schedule()+0x3fd: sibling call from callable instruction with changed frame pointer ... so that scripts that pick up compiler warnings will notice them. All known warnings triggered by the tool are fixed by the tree, most of the commits in fact prepare the kernel to be warning-free. Most of them are bugfixes or cleanups that stand on their own, but there are also some annotations of 'special' stack frames for justified cases such entries to JIT-ed code (BPF) or really special boot time code. There are two other long-term motivations behind this tool as well: - To improve the quality and reliability of kernel stack frames, so that they can be used for optimized live patching. - To create independent infrastructure to check the correctness of CFI stack frames at build time. CFI debuginfo is notoriously unreliable and we cannot use it in the kernel as-is without extra checking done both on the kernel side and on the build side. The quality of kernel stack frames matters to debuggability as well, so IMO we can merge this without having to consider the live patching or CFI debuginfo angle" * 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (52 commits) objtool: Only print one warning per function objtool: Add several performance improvements tools: Copy hashtable.h into tools directory objtool: Fix false positive warnings for functions with multiple switch statements objtool: Rename some variables and functions objtool: Remove superflous INIT_LIST_HEAD objtool: Add helper macros for traversing instructions objtool: Fix false positive warnings related to sibling calls objtool: Compile with debugging symbols objtool: Detect infinite recursion objtool: Prevent infinite recursion in noreturn detection objtool: Detect and warn if libelf is missing and don't break the build tools: Support relative directory path for 'O=' objtool: Support CROSS_COMPILE x86/asm/decoder: Use explicitly signed chars objtool: Enable stack metadata validation on 64-bit x86 objtool: Add CONFIG_STACK_VALIDATION option objtool: Add tool to perform compile-time stack metadata validation x86/kprobes: Mark kretprobe_trampoline() stack frame as non-standard sched: Always inline context_switch() ...

It enforces a set of rules on asm code and C inline assembly code so that stack traces can be reliable. For each function, it recursively follows all possible code paths and validates the correct frame pointer state at each instruction. It also follows code paths involving kernel special sections, like .altinstructions, __jump_table, and __ex_table, which can add alternative execution paths to a given instruction (or set of instructions). Similarly, it knows how to follow switch statements, for which gcc sometimes uses jump tables. Here are some of the benefits of validating stack metadata: a) More reliable stack traces for frame pointer enabled kernels Frame pointers are used for debugging purposes. They allow runtime code and debug tools to be able to walk the stack to determine the chain of function call sites that led to the currently executing code. For some architectures, frame pointers are enabled by CONFIG_FRAME_POINTER. For some other architectures they may be required by the ABI (sometimes referred to as "backchain pointers"). For C code, gcc automatically generates instructions for setting up frame pointers when the -fno-omit-frame-pointer option is used. But for asm code, the frame setup instructions have to be written by hand, which most people don't do. So the end result is that CONFIG_FRAME_POINTER is honored for C code but not for most asm code. For stack traces based on frame pointers to be reliable, all functions which call other functions must first create a stack frame and update the frame pointer. If a first function doesn't properly create a stack frame before calling a second function, the *caller* of the first function will be skipped on the stack trace. For example, consider the following example backtrace with frame pointers enabled: [<ffffffff81812584>] dump_stack+0x4b/0x63 [<ffffffff812d6dc2>] cmdline_proc_show+0x12/0x30 [<ffffffff8127f568>] seq_read+0x108/0x3e0 [<ffffffff812cce62>] proc_reg_read+0x42/0x70 [<ffffffff81256197>] __vfs_read+0x37/0x100 [<ffffffff81256b16>] vfs_read+0x86/0x130 [<ffffffff81257898>] SyS_read+0x58/0xd0 [<ffffffff8181c1f2>] entry_SYSCALL_64_fastpath+0x12/0x76 It correctly shows that the caller of cmdline_proc_show() is seq_read(). If we remove the frame pointer logic from cmdline_proc_show() by replacing the frame pointer related instructions with nops, here's what it looks like instead: [<ffffffff81812584>] dump_stack+0x4b/0x63 [<ffffffff812d6dc2>] cmdline_proc_show+0x12/0x30 [<ffffffff812cce62>] proc_reg_read+0x42/0x70 [<ffffffff81256197>] __vfs_read+0x37/0x100 [<ffffffff81256b16>] vfs_read+0x86/0x130 [<ffffffff81257898>] SyS_read+0x58/0xd0 [<ffffffff8181c1f2>] entry_SYSCALL_64_fastpath+0x12/0x76 Notice that cmdline_proc_show()'s caller, seq_read(), has been skipped. Instead the stack trace seems to show that cmdline_proc_show() was called by proc_reg_read(). The benefit of "objtool check" here is that because it ensures that *all* functions honor CONFIG_FRAME_POINTER, no functions will ever[*] be skipped on a stack trace. [*] unless an interrupt or exception has occurred at the very beginning of a function before the stack frame has been created, or at the very end of the function after the stack frame has been destroyed. This is an inherent limitation of frame pointers. b) 100% reliable stack traces for DWARF enabled kernels This is not yet implemented. For more details about what is planned, see tools/objtool/Documentation/stack-validation.txt. c) Higher live patching compatibility rate This is not yet implemented. For more details about what is planned, see tools/objtool/Documentation/stack-validation.txt. To achieve the validation, "objtool check" enforces the following rules: 1. Each callable function must be annotated as such with the ELF function type. In asm code, this is typically done using the ENTRY/ENDPROC macros. If objtool finds a return instruction outside of a function, it flags an error since that usually indicates callable code which should be annotated accordingly. This rule is needed so that objtool can properly identify each callable function in order to analyze its stack metadata. 2. Conversely, each section of code which is *not* callable should *not* be annotated as an ELF function. The ENDPROC macro shouldn't be used in this case. This rule is needed so that objtool can ignore non-callable code. Such code doesn't have to follow any of the other rules. 3. Each callable function which calls another function must have the correct frame pointer logic, if required by CONFIG_FRAME_POINTER or the architecture's back chain rules. This can by done in asm code with the FRAME_BEGIN/FRAME_END macros. This rule ensures that frame pointer based stack traces will work as designed. If function A doesn't create a stack frame before calling function B, the _caller_ of function A will be skipped on the stack trace. 4. Dynamic jumps and jumps to undefined symbols are only allowed if: a) the jump is part of a switch statement; or b) the jump matches sibling call semantics and the frame pointer has the same value it had on function entry. This rule is needed so that objtool can reliably analyze all of a function's code paths. If a function jumps to code in another file, and it's not a sibling call, objtool has no way to follow the jump because it only analyzes a single file at a time. 5. A callable function may not execute kernel entry/exit instructions. The only code which needs such instructions is kernel entry code, which shouldn't be be in callable functions anyway. This rule is just a sanity check to ensure that callable functions return normally. It currently only supports x86_64. I tried to make the code generic so that support for other architectures can hopefully be plugged in relatively easily. On my Lenovo laptop with a i7-4810MQ 4-core/8-thread CPU, building the kernel with objtool checking every .o file adds about three seconds of total build time. It hasn't been optimized for performance yet, so there are probably some opportunities for better build performance.
