of the library -=== - - ELF -> Specifications -> Objects -> Links - -ELF ---- - -BPF is usually produced by using Clang to compile a subset of C. Clang outputs -an ELF file which contains program byte code (aka BPF), but also metadata for -maps used by the program. The metadata follows the conventions set by libbpf -shipped with the kernel. Certain ELF sections have special meaning -and contain structures defined by libbpf. Newer versions of clang emit -additional metadata in BPF Type Format (aka BTF). - -The library aims to be compatible with libbpf so that moving from a C toolchain -to a Go one creates little friction. To that end, the [ELF reader](elf_reader.go) -is tested against the Linux selftests and avoids introducing custom behaviour -if possible. - -The output of the ELF reader is a `CollectionSpec` which encodes -all of the information contained in the ELF in a form that is easy to work with -in Go. - -### BTF - -The BPF Type Format describes more than just the types used by a BPF program. It -includes debug aids like which source line corresponds to which instructions and -what global variables are used. - -[BTF parsing](internal/btf/) lives in a separate internal package since exposing -it would mean an additional maintenance burden, and because the API still -has sharp corners. The most important concept is the `btf.Type` interface, which -also describes things that aren't really types like `.rodata` or `.bss` sections. -`btf.Type`s can form cyclical graphs, which can easily lead to infinite loops if -one is not careful. Hopefully a safe pattern to work with `btf.Type` emerges as -we write more code that deals with it. - -Specifications ---- - -`CollectionSpec`, `ProgramSpec` and `MapSpec` are blueprints for in-kernel -objects and contain everything necessary to execute the relevant `bpf(2)` -syscalls. Since the ELF reader outputs a `CollectionSpec` it's possible to -modify clang-compiled BPF code, for example to rewrite constants. At the same -time the [asm](asm/) package provides an assembler that can be used to generate -`ProgramSpec` on the fly. - -Creating a spec should never require any privileges or be restricted in any way, -for example by only allowing programs in native endianness. This ensures that -the library stays flexible. - -Objects ---- - -`Program` and `Map` are the result of loading specs into the kernel. Sometimes -loading a spec will fail because the kernel is too old, or a feature is not -enabled. There are multiple ways the library deals with that: - -* Fallback: older kernels don't allow naming programs and maps. The library - automatically detects support for names, and omits them during load if - necessary. This works since name is primarily a debug aid. - -* Sentinel error: sometimes it's possible to detect that a feature isn't available. - In that case the library will return an error wrapping `ErrNotSupported`. - This is also useful to skip tests that can't run on the current kernel. - -Once program and map objects are loaded they expose the kernel's low-level API, -e.g. `NextKey`. Often this API is awkward to use in Go, so there are safer -wrappers on top of the low-level API, like `MapIterator`. The low-level API is -useful when our higher-level API doesn't support a particular use case. - -Links ---- - -BPF can be attached to many different points in the kernel and newer BPF hooks -tend to use bpf_link to do so. Older hooks unfortunately use a combination of -syscalls, netlink messages, etc. Adding support for a new link type should not -pull in large dependencies like netlink, so XDP programs or tracepoints are -out of scope. - -Each bpf_link_type has one corresponding Go type, e.g. `link.tracing` corresponds -to BPF_LINK_TRACING. In general, these types should be unexported as long as they -don't export methods outside of the Link interface. Each Go type may have multiple -exported constructors. For example `AttachTracing` and `AttachLSM` create a -tracing link, but are distinct functions since they may require different arguments. diff --git a/vendor/github.com/cilium/ebpf/CODE_OF_CONDUCT.md b/vendor/github.com/cilium/ebpf/CODE_OF_CONDUCT.md deleted file mode 100644 index 8e42838c5a..0000000000 --- a/vendor/github.com/cilium/ebpf/CODE_OF_CONDUCT.md +++ /dev/null @@ -1,46 +0,0 @@ -# Contributor Covenant Code of Conduct - -## Our Pledge - -In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation. - -## Our Standards - -Examples of behavior that contributes to creating a positive environment include: - -* Using welcoming and inclusive language -* Being respectful of differing viewpoints and experiences -* Gracefully accepting constructive criticism -* Focusing on what is best for the community -* Showing empathy towards other community members - -Examples of unacceptable behavior by participants include: - -* The use of sexualized language or imagery and unwelcome sexual attention or advances -* Trolling, insulting/derogatory comments, and personal or political attacks -* Public or private harassment -* Publishing others' private information, such as a physical or electronic address, without explicit permission -* Other conduct which could reasonably be considered inappropriate in a professional setting - -## Our Responsibilities - -Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior. - -Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful. - -## Scope - -This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community.
