git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking updates from Ingo Molnar: "The biggest part of this tree is the new auto-generated atomics API wrappers by Mark Rutland. The primary motivation was to allow instrumentation without uglifying the primary source code. The linecount increase comes from adding the auto-generated files to the Git space as well: include/asm-generic/atomic-instrumented.h | 1689 ++++++++++++++++-- include/asm-generic/atomic-long.h | 1174 ++++++++++--- include/linux/atomic-fallback.h | 2295 +++++++++++++++++++++++++ include/linux/atomic.h | 1241 +------------ I preferred this approach, so that the full call stack of the (already complex) locking APIs is still fully visible in 'git grep'. But if this is excessive we could certainly hide them. There's a separate build-time mechanism to determine whether the headers are out of date (they should never be stale if we do our job right). Anyway, nothing from this should be visible to regular kernel developers. Other changes: - Add support for dynamic keys, which removes a source of false positives in the workqueue code, among other things (Bart Van Assche) - Updates to tools/memory-model (Andrea Parri, Paul E. McKenney) - qspinlock, wake_q and lockdep micro-optimizations (Waiman Long) - misc other updates and enhancements" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (48 commits) locking/lockdep: Shrink struct lock_class_key locking/lockdep: Add module_param to enable consistency checks lockdep/lib/tests: Test dynamic key registration lockdep/lib/tests: Fix run_tests.sh kernel/workqueue: Use dynamic lockdep keys for workqueues locking/lockdep: Add support for dynamic keys locking/lockdep: Verify whether lock objects are small enough to be used as class keys locking/lockdep: Check data structure consistency locking/lockdep: Reuse lock chains that have been freed locking/lockdep: Fix a comment in add_chain_cache() locking/lockdep: Introduce lockdep_next_lockchain() and lock_chain_count() locking/lockdep: Reuse list entries that are no longer in use locking/lockdep: Free lock classes that are no longer in use locking/lockdep: Update two outdated comments locking/lockdep: Make it easy to detect whether or not inside a selftest locking/lockdep: Split lockdep_free_key_range() and lockdep_reset_lock() locking/lockdep: Initialize the locks_before and locks_after lists earlier locking/lockdep: Make zap_class() remove all matching lock order entries locking/lockdep: Reorder struct lock_class members locking/lockdep: Avoid that add_chain_cache() adds an invalid chain to the cache ...

2019-03-05mm: convert PG_balloon to PG_offlineDavid Hildenbrand1-1/+1
PG_balloon was introduced to implement page migration/compaction for pages inflated in virtio-balloon. Nowadays, it is only a marker that a page is part of virtio-balloon and therefore logically offline. We also want to make use of this flag in other balloon drivers - for inflated pages or when onlining a section but keeping some pages offline (e.g. used right now by XEN and Hyper-V via set_online_page_callback()). We are going to expose this flag to dump tools like makedumpfile. But instead of exposing PG_balloon, let's generalize the concept of marking pages as logically offline, so it can be reused for other purposes later on. Rename PG_balloon to PG_offline. This is an indicator that the page is logically offline, the content stale and that it should not be touched (e.g. a hypervisor would have to allocate backing storage in order for the guest to dump an unused page). We can then e.g. exclude such pages from dumps. We replace and reuse KPF_BALLOON (23), as this shouldn't really harm (and for now the semantics stay the same). In following patches, we will make use of this bit also in other balloon drivers. While at it, document PGTABLE.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-03-04 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add AF_XDP support to libbpf. Rationale is to facilitate writing AF_XDP applications by offering higher-level APIs that hide many of the details of the AF_XDP uapi. Sample programs are converted over to this new interface as well, from Magnus. 2) Introduce a new cant_sleep() macro for annotation of functions that cannot sleep and use it in BPF_PROG_RUN() to assert that BPF programs run under preemption disabled context, from Peter. 3) Introduce per BPF prog stats in order to monitor the usage of BPF; this is controlled by kernel.bpf_stats_enabled sysctl knob where monitoring tools can make use of this to efficiently determine the average cost of programs, from Alexei. 4) Split up BPF selftest's test_progs similarly as we already did with test_verifier. This allows to further reduce merge conflicts in future and to get more structure into our quickly growing BPF selftest suite, from Stanislav. 5) Fix a bug in BTF's dedup algorithm which can cause an infinite loop in some circumstances; also various BPF doc fixes and improvements, from Andrii. 6) Various BPF sample cleanups and migration to libbpf in order to further isolate the old sample loader code (so we can get rid of it at some point), from Jakub. 7) Add a new BPF helper for BPF cgroup skb progs that allows to set ECN CE code point and a Host Bandwidth Manager (HBM) sample program for limiting the bandwidth used by v2 cgroups, from Lawrence. 8) Enable write access to skb->queue_mapping from tc BPF egress programs in order to let BPF pick TX queue, from Jesper. 9) Fix a bug in BPF spinlock handling for map-in-map which did not propagate spin_lock_off to the meta map, from Yonghong. 10) Fix a bug in the new per-CPU BPF prog counters to properly initialize stats for each CPU, from Eric. 11) Add various BPF helper prototypes to selftest's bpf_helpers.h, from Willem. 12) Fix various BPF samples bugs in XDP and tracing progs, from Toke, Daniel and Yonghong. 13) Silence preemption splat in test_bpf after BPF_PROG_RUN() enforces it now everywhere, from Anders. 14) Fix a signedness bug in libbpf's btf_dedup_ref_type() to get error handling working, from Dan. 15) Fix bpftool documentation and auto-completion with regards to stream_{verdict,parser} attach types, from Alban. ==================== Signed-off-by: David S.

Add new prog_tests directory where tests are supposed to land. Each prog_tests/<filename>.c is expected to have a global function with signature 'void test_<filename>(void)'. Makefile automatically generates prog_tests/tests.h file with entry for each prog_tests file: #ifdef DECLARE extern void test_<filename>(void); ... #endif #ifdef CALL test_<filename>(); ... #endif prog_tests/tests.h is included in test_progs.c in two places with appropriate defines. This scheme allows us to move each function with a separate patch without breaking anything. Compared to the recent verifier split, each separate file here is a compilation unit and test_progs.[ch] is now used as a place to put some common routines that might be used by multiple tests.

2019-03-01selftests/bpf: add btf_dedup test of FWD/STRUCT resolutionAndrii Nakryiko1-0/+45
This patch adds a btf_dedup test exercising logic of STRUCT<->FWD resolution and validating that STRUCT is not resolved to a FWD. It also forces hash collisions, forcing both FWD and STRUCT to be candidates for each other. Previously this condition caused infinite loop due to FWD pointing to STRUCT and STRUCT pointing to its FWD.

2019-03-01btf: fix bug with resolving STRUCT/UNION into corresponding FWDAndrii Nakryiko1-3/+17
When checking available canonical candidates for struct/union algorithm utilizes btf_dedup_is_equiv to determine if candidate is suitable. This check is not enough when candidate is corresponding FWD for that struct/union, because according to equivalence logic they are equivalent. When it so happens that FWD and STRUCT/UNION end in hashing to the same bucket, it's possible to create remapping loop from FWD to STRUCT and STRUCT to same FWD, which will cause btf_dedup() to loop forever. This patch fixes the issue by additionally checking that type and canonical candidate are strictly equal (utilizing btf_equal_struct).

2019-03-01btf: allow to customize dedup hash table sizeAndrii Nakryiko2-17/+37
Default size of dedup table (16k) is good enough for most binaries, even typical vmlinux images. But there are cases of binaries with huge amount of BTF types (e.g., allyesconfig variants of kernel), which benefit from having bigger dedup table size to lower amount of unnecessary hash collisions. Tools like pahole, thus, can tune this parameter to reach optimal performance. This change also serves double purpose of allowing tests to force hash collisions to test some corner cases, used in follow up patch.
