2018-11-26net/mlx5: EQ, Introduce atomic notifier chain subscription APISaeed Mahameed2-3/+23
Use atomic_notifier_chain to fire firmware events at internal mlx5 core components such as eswitch/fpga/clock/FW tracer/etc.., this is to avoid explicit calls from low level mlx5_core to upper components and to simplify the mlx5_core API for future developments. Simply provide register/unregister notifiers API and call the notifier chain on firmware async events. Example: to subscribe to a FW event: struct mlx5_nb port_event; MLX5_NB_INIT(&port_event, port_event_handler, PORT_CHANGE); mlx5_eq_notifier_register(mdev, &port_event); where: - port_event_handler is the notifier block callback. - PORT_EVENT is the suffix of MLX5_EVENT_TYPE_PORT_CHANGE. The above will guarantee that port_event_handler will receive all FW events of the type MLX5_EVENT_TYPE_PORT_CHANGE. To receive all FW/HW events one can subscribe to MLX5_EVENT_TYPE_NOTIFY_ANY. The next few patches will start moving all mlx5 core components to use this new API and cleanup mlx5_eq_async_int misx handler from component explicit calls and specific logic.

2018-11-20net/mlx5: EQ, Generic EQSaeed Mahameed1-0/+39
Add mlx5_eq_{create/destroy}_generic APIs and EQE access methods, for mlx5 core consumers generic EQs. This API will be used in downstream patch to move page fault (RDMA ODP) EQ logic into mlx5_ib rdma driver, hence it will use a generic EQ. Current mlx5 EQ allocation scheme: On load mlx5 allocates 4 (for async) + #cores (for data completions) MSIX vectors, mlx5 core will assign 3 MSIX vectors for internal async EQs and will use all of the #cores MSIX vectors for completion EQs, (One vector is going to be reserved for a generic EQ). After this patch an external user (e.g mlx5_ib) of mlx5_core can use this new API to create new generic EQs with the reserved msix vector index for that eq.

2018-11-20net/mlx5: EQ, Different EQ typesSaeed Mahameed2-10/+2
In mlx5 we have three types of usages for EQs, 1. Asynchronous EQs, used internally by mlx5 core for a. FW command completions b. FW page requests c. one EQ for all other Asynchronous events 2. Completion EQs, used for CQ completion (we create one per core) 3. *Special type of EQ (page fault) used for RDMA on demand paging (ODP). *The 3rd type shouldn't be special at least in mlx5 core, it is yet another async events EQ with specific use case, it will be removed in the next two patches, and will completely move its logic to mlx5_ib, as it is rdma specific. In this patch we remove use case (eq type) specific fields from struct mlx5_eq into a new eq type specific structures. struct mlx5_eq_async; truct mlx5_eq_comp; struct mlx5_eq_pagefault; Separate between their type specific flows. In the future we will allow users to create there own generic EQs. for now we will allow only one for ODP in next patches. We will introduce event listeners registration API for those who want to receive mlx5 async events. After that mlx5 eq handling will be clean from feature/user specific handling.

2018-11-03mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmaskMichal Hocko2-8/+6
THP allocation mode is quite complex and it depends on the defrag mode. This complexity is hidden in alloc_hugepage_direct_gfpmask from a large part currently. The NUMA special casing (namely __GFP_THISNODE) is however independent and placed in alloc_pages_vma currently. This both adds an unnecessary branch to all vma based page allocation requests and it makes the code more complex unnecessarily as well. Not to mention that e.g. shmem THP used to do the node reclaiming unconditionally regardless of the defrag mode until recently. This was not only unexpected behavior but it was also hardly a good default behavior and I strongly suspect it was just a side effect of the code sharing more than a deliberate decision which suggests that such a layering is wrong. Get rid of the thp special casing from alloc_pages_vma and move the logic to alloc_hugepage_direct_gfpmask. __GFP_THISNODE is applied to the resulting gfp mask only when the direct reclaim is not requested and when there is no explicit numa binding to preserve the current logic. Please note that there's also a slight difference wrt MPOL_BIND now. The previous code would avoid using __GFP_THISNODE if the local node was outside of policy_nodemask(). After this patch __GFP_THISNODE is avoided for all MPOL_BIND policies. So there's a difference that if local node is actually allowed by the bind policy's nodemask, previously __GFP_THISNODE would be added, but now it won't be. From the behavior POV this is still correct because the policy nodemask is used.

We also introduce the ability for the ->remap_file_range methods to return short clones so that clones for vfs_copy_file_range() don't get rejected if the entire range can't be cloned. It also allows filesystems to sliently skip deduplication of partial EOF blocks if they are not capable of doing so without requiring errors to be thrown to userspace.

The main idea behind the series is to use feature checking macros (i.e. __has_attribute) instead of compiler version checks (e.g. GCC_VERSION), which are compiler-agnostic (so they can be shared, reducing the size of compiler-specific headers) and version-agnostic. Other related improvements have been performed in the headers as well, which on top of the use of __has_attribute it has amounted to a significant simplification of these headers (e.g. GCC_VERSION is now only guarding a few non-attribute macros). This series should also help the efforts to support compiling the kernel with clang and icc. A fair amount of documentation and comments have also been added, clarified or removed; and the headers are now more readable, which should help kernel developers in general. The series was triggered due to the move to gcc >= 4.6. In turn, this series has also triggered Sparse to gain the ability to recognize __has_attribute on its own. Finally, the __nonstring variable attribute series has been also applied on top; plus two related patches from Nick Desaulniers for unreachable() that came a bit afterwards" * tag 'compiler-attributes-for-linus-4.20-rc1' of https://github.com/ojeda/linux: compiler-gcc: remove comment about gcc 4.5 from unreachable() compiler.h: update definition of unreachable() Compiler Attributes: ext4: remove local __nonstring definition Compiler Attributes: auxdisplay: panel: use __nonstring Compiler Attributes: enable -Wstringop-truncation on W=1 (gcc >= 8) Compiler Attributes: add support for __nonstring (gcc >= 8) Compiler Attributes: add MAINTAINERS entry Compiler Attributes: add Doc/process/programming-language.rst Compiler Attributes: remove uses of __attribute__ from compiler.h Compiler Attributes: KENTRY used twice the "used" attribute Compiler Attributes: use feature checks instead of version checks Compiler Attributes: add missing SPDX ID in compiler_types.h Compiler Attributes: remove unneeded sparse (__CHECKER__) tests Compiler Attributes: homogenize __must_be_array Compiler Attributes: remove unneeded tests Compiler Attributes: always use the extra-underscores syntax Compiler Attributes: remove unused attributes

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull stackleak gcc plugin from Kees Cook: "Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin was ported from grsecurity by Alexander Popov. It provides efficient stack content poisoning at syscall exit. This creates a defense against at least two classes of flaws: - Uninitialized stack usage. (We continue to work on improving the compiler to do this in other ways: e.g. unconditional zero init was proposed to GCC and Clang, and more plugin work has started too). - Stack content exposure. By greatly reducing the lifetime of valid stack contents, exposures via either direct read bugs or unknown cache side-channels become much more difficult to exploit. This complements the existing buddy and heap poisoning options, but provides the coverage for stacks. The x86 hooks are included in this series (which have been reviewed by Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already been merged through the arm64 tree (written by Laura Abbott and reviewed by Mark Rutland and Will Deacon). With VLAs having been removed this release, there is no need for alloca() protection, so it has been removed from the plugin" * tag 'stackleak-v4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: arm64: Drop unneeded stackleak_check_alloca() stackleak: Allow runtime disabling of kernel stack erasing doc: self-protection: Add information about STACKLEAK feature fs/proc: Show STACKLEAK metrics in the /proc file system lkdtm: Add a test for STACKLEAK gcc-plugins: Add STACKLEAK plugin for tracking the kernel stack x86/entry: Add STACKLEAK erasing the kernel stack at the end of syscalls
2018-11-01SUNRPC: Use atomic(64)_t for seq_send(64)Paul Burton1-5/+2
The seq_send & seq_send64 fields in struct krb5_ctx are used as atomically incrementing counters. This is implemented using cmpxchg() & cmpxchg64() to implement what amount to custom versions of atomic_fetch_inc() & atomic64_fetch_inc(). Besides the duplication, using cmpxchg64() has another major drawback in that some 32 bit architectures don't provide it. As such commit 571ed1fd2390 ("SUNRPC: Replace krb5_seq_lock with a lockless scheme") resulted in build failures for some architectures. Change seq_send to be an atomic_t and seq_send64 to be an atomic64_t, then use atomic(64)_* functions to manipulate the values. The atomic64_t type & associated functions are provided even on architectures which lack real 64 bit atomic memory access via CONFIG_GENERIC_ATOMIC64 which uses spinlocks to serialize access. This fixes the build failures for architectures lacking cmpxchg64(). A potential alternative that was raised would be to provide cmpxchg64() on the 32 bit architectures that currently lack it, using spinlocks. However this would provide a version of cmpxchg64() with semantics a little different to the implementations on architectures with real 64 bit atomics - the spinlock-based implementation would only work if all access to the memory used with cmpxchg64() is *always* performed using cmpxchg64(). That is not currently a requirement for users of cmpxchg64(), and making it one seems questionable. As such avoiding cmpxchg64() outside of architecture-specific code seems best, particularly in cases where atomic64_t seems like a better fit anyway. The CONFIG_GENERIC_ATOMIC64 implementation of atomic64_* functions will use spinlocks & so faces the same issue, but with the key difference that the memory backing an atomic64_t ought to always be accessed via the atomic64_* functions anyway making the issue moot.

2018-11-01x86/compat: Adjust in_compat_syscall() to generic code under !COMPATDmitry Safonov1-2/+2
The result of in_compat_syscall() can be pictured as: x86 platform: --------------------------------------------------- | Arch\syscall | 64-bit | ia32 | x32 | |-------------------------------------------------| | x86_64 | false | true | true | |-------------------------------------------------| | i686 | | <true> | | --------------------------------------------------- Other platforms: ------------------------------------------- | Arch\syscall | 64-bit | compat | |-----------------------------------------| | 64-bit | false | true | |-----------------------------------------| | 32-bit(?) | | <false> | ------------------------------------------- As seen, the result of in_compat_syscall() on generic 32-bit platform differs from i686. There is no reason for in_compat_syscall() == true on native i686. It also easy to misread code if the result on native 32-bit platform differs between arches. Because of that non arch-specific code has many places with: if (IS_ENABLED(CONFIG_COMPAT) && in_compat_syscall()) in different variations. It looks-like the only non-x86 code which uses in_compat_syscall() not under CONFIG_COMPAT guard is in amd/amdkfd. But according to the commit a18069c132cb ("amdkfd: Disable support for 32-bit user processes"), it actually should be disabled on native i686. Rename in_compat_syscall() to in_32bit_syscall() for x86-specific code and make in_compat_syscall() false under !CONFIG_COMPAT. A follow on patch will clean up generic users which were forced to check IS_ENABLED(CONFIG_COMPAT) with in_compat_syscall().

Miroslav Lichvar from Red Hat or should I say IBM now? Updates the PHC timecounter interval for igb so that it gets updated at least once every 550 seconds. Ngai-Mint provides a fix for fm10k to prevent a soft lockup or system crash by adding a new condition to determine if the SM mailbox is in the correct state before proceeding. Jake provides several fm10k fixes, first one marks complier aborts as non-fatal since on some platforms trigger machine check errors when the compile aborts. Added missing device ids to the in-kernel driver. Due to the recent fixes, bumped the driver version. I (Jeff Kirsher) fixed a XFRM_ALGO dependency for both ixgbe and ixgbevf. This fix was based on the original work from Arnd Bergmann, which only fixed ixgbe. Mitch provides a fix for i40e/avf to update the status codes, which resolves an issue between a mis-match between i40e and the iavf driver, which also supports the ice LAN driver. Radoslaw fixes the ixgbe where the driver is logging a message about spoofed packets detected when the VF is re-started with a different MAC address. ==================== Signed-off-by: David S.

2018-10-31bpf: fix partial copy of map_ptr when dst is scalarDaniel Borkmann1-0/+3
ALU operations on pointers such as scalar_reg += map_value_ptr are handled in adjust_ptr_min_max_vals(). Problem is however that map_ptr and range in the register state share a union, so transferring state through dst_reg->range = ptr_reg->range is just buggy as any new map_ptr in the dst_reg is then truncated (or null) for subsequent checks. Fix this by adding a raw member and use it for copying state over to dst_reg.
