2019-09-25augmented rbtree: rework the RB_DECLARE_CALLBACKS macro definitionMichel Lespinasse
Change the definition of the RBCOMPUTE function. The propagate callback repeatedly calls RBCOMPUTE as it moves from leaf to root. it wants to stop recomputing once the augmented subtree information doesn't change. This was previously checked using the == operator, but that only works when the augmented subtree information is a scalar field. This commit modifies the RBCOMPUTE function so that it now sets the augmented subtree information instead of returning it, and returns a boolean value indicating if the propagate callback should stop. The motivation for this change is that I want to introduce augmented rbtree uses where the augmented data for the subtree is a struct instead of a scalar.

2019-09-25augmented rbtree: add new RB_DECLARE_CALLBACKS_MAX macroMichel Lespinasse
Add RB_DECLARE_CALLBACKS_MAX, which generates augmented rbtree callbacks for the case where the augmented value is a scalar whose definition follows a max(f(node)) pattern. This actually covers all present uses of RB_DECLARE_CALLBACKS, and saves some (source) code duplication in the various RBCOMPUTE function definitions.

2019-09-25augmented rbtree: add comments for RB_DECLARE_CALLBACKS macroMichel Lespinasse
Patch series "make RB_DECLARE_CALLBACKS more generic", v3. These changes are intended to make the RB_DECLARE_CALLBACKS macro more generic (allowing the aubmented subtree information to be a struct instead of a scalar). I have verified the compiled lib/interval_tree.o and mm/mmap.o files to check that they didn't change. This held as expected for interval_tree.o; mmap.o did have some changes which could be reverted by marking __vma_link_rb as noinline. I did not add such a change to the patchset; I felt it was reasonable enough to leave the inlining decision up to the compiler. This patch (of 3): Add a short comment summarizing the arguments to RB_DECLARE_CALLBACKS. The arguments are also now capitalized. This copies the style of the INTERVAL_TREE_DEFINE macro. No functional changes in this commit, only comments and capitalization.

As was already noted in rbtree.h, the logic to cache rb_first (or rb_last) can easily be implemented externally to the core rbtree api. This commit takes the changes applied to the include/linux/ and lib/ rbtree files in 9f973cb38088 ("lib/rbtree: avoid generating code twice for the cached versions"), and applies these to the tools/include/linux/ and tools/lib/ files as well to keep them synchronized.

Daniel Borkmann says: ==================== The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add the ability to use unaligned chunks in the AF_XDP umem. By relaxing where the chunks can be placed, it allows to use an arbitrary buffer size and place whenever there is a free address in the umem. Helps more seamless DPDK AF_XDP driver integration. Support for i40e, ixgbe and mlx5e, from Kevin and Maxim. 2) Addition of a wakeup flag for AF_XDP tx and fill rings so the application can wake up the kernel for rx/tx processing which avoids busy-spinning of the latter, useful when app and driver is located on the same core. Support for i40e, ixgbe and mlx5e, from Magnus and Maxim. 3) bpftool fixes for printf()-like functions so compiler can actually enforce checks, bpftool build system improvements for custom output directories, and addition of 'bpftool map freeze' command, from Quentin. 4) Support attaching/detaching XDP programs from 'bpftool net' command, from Daniel. 5) Automatic xskmap cleanup when AF_XDP socket is released, and several barrier/{read,write}_once fixes in AF_XDP code, from Björn. 6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf inclusion as well as libbpf versioning improvements, from Andrii. 7) Several new BPF kselftests for verifier precision tracking, from Alexei. 8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya. 9) And more BPF kselftest improvements all over the place, from Stanislav. 10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub. 11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan. 12) Add BPF-to-BPF call and BTF line info support for s390x JIT, from Yauheni. 13) Small optimization in arm64 JIT to spare 1 insns for BPF_MOD, from Jerin. 14) Fix an error check in bpf_tcp_gen_syncookie() helper, from Petar. 15) Various minor fixes and cleanups, from Nathan, Masahiro, Masanari, Peter, Wei, Yue. ==================== Signed-off-by: David S.

2019-08-31libbpf: add flags to umem configKevin Laatz
This patch adds a 'flags' field to the umem_config and umem_reg structs. This will allow for more options to be added for configuring umems. The first use for the flags field is to add a flag for unaligned chunks mode. These flags can either be user-provided or filled with a default. Since we change the size of the xsk_umem_config struct, we need to version the ABI. This patch includes the ABI versioning for xsk_umem__create. The Makefile was also updated to handle multiple function versions in check-abi.

2019-08-15tools: bpftool: move "__printf()" attributes to header fileQuentin Monnet
Some functions in bpftool have a "__printf()" format attributes to tell the compiler they should expect printf()-like arguments. But because these attributes are not used for the function prototypes in the header files, the compiler does not run the checks everywhere the functions are used, and some mistakes on format string and corresponding arguments slipped in over time. Let's move the __printf() attributes to the correct places. Note: We add guards around the definition of GCC_VERSION in tools/include/linux/compiler-gcc.h to prevent a conflict in jit_disasm.c on GCC_VERSION from headers pulled via libbfd.

Renaming docs seems to be en vogue at the moment, so fix on of the grossly misnamed directories. We usually never use "virtual" as a shortcut for virtualization in the kernel, but always virt, as seen in the virt/ top-level directory. Fix up the documentation to match that.
