Daniel Borkmann says: ==================== pull-request: bpf-next 2018-01-17 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add initial BPF map offloading for nfp driver. Currently only programs were supported so far w/o being able to access maps. Offloaded programs are right now only allowed to perform map lookups, and control path is responsible for populating the maps. BPF core infrastructure along with nfp implementation is provided, from Jakub. 2) Various follow-ups to Josef's BPF error injections. More specifically that includes: properly check whether the error injectable event is on function entry or not, remove the percpu bpf_kprobe_override and rather compare instruction pointer with original one, separate error-injection from kprobes since it's not limited to it, add injectable error types in order to specify what is the expected type of failure, and last but not least also support the kernel's fault injection framework, all from Masami. 3) Various misc improvements and cleanups to the libbpf Makefile. That is, fix permissions when installing BPF header files, remove unused variables and functions, and also install the libbpf.h header, from Jesper. 4) When offloading to nfp JIT and the BPF insn is unsupported in the JIT, then reject right at verification time. Also fix libbpf with regards to ELF section name matching by properly treating the program type as prefix. Both from Quentin. 5) Add -DPACKAGE to bpftool when including bfd.h for the disassembler. This is needed, for example, when building libfd from source as bpftool doesn't supply a config.h for bfd.h. Fix from Jiong. 6) xdp_convert_ctx_access() is simplified since it doesn't need to set target size during verification, from Jesper. 7) Let bpftool properly recognize BPF_PROG_TYPE_CGROUP_DEVICE program types, from Roman. 8) Various functions in BPF cpumap were not declared static, from Wei. 9) Fix a double semicolon in BPF samples, from Luis. ==================== Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
