Struct LibbpfOpts 

pub struct LibbpfOpts {
    pub relaxed_maps: Option<bool>,
    pub pin_root_path: Option<String>,
    pub kconfig: Option<String>,
    pub btf_custom_path: Option<String>,
    pub bpf_token_path: Option<String>,
}

Fields

relaxed_maps: Option<bool>

Parse map definitions non-strictly, allowing extra attributes/data.

pin_root_path: Option<String>

Maps that set the ‘pinning’ attribute in their definition will have their pin_path attribute set to a file in this directory, and be auto-pinned to that path on load; defaults to “/sys/fs/bpf”.

kconfig: Option<String>

Additional kernel config content that augments and overrides system Kconfig for CONFIG_xxx externs.

btf_custom_path: Option<String>

Path to the custom BTF to be used for BPF CO-RE relocations. This custom BTF completely replaces the use of vmlinux BTF for the purpose of CO-RE relocations. NOTE: any other BPF feature (e.g., fentry/fexit programs, struct_ops, etc) will need actual kernel BTF at /sys/kernel/btf/vmlinux.

bpf_token_path: Option<String>

Path to BPF FS mount point to derive BPF token from. Created BPF token will be used for all bpf() syscall operations that accept BPF token (e.g., map creation, BTF and program loads, etc) automatically within instantiated BPF object. If bpf_token_path is not specified, libbpf will consult LIBBPF_BPF_TOKEN_PATH environment variable. If set, it will be taken as a value of bpf_token_path option and will force libbpf to either create BPF token from provided custom BPF FS path, or will disable implicit BPF token creation, if envvar value is an empty string. bpf_token_path overrides LIBBPF_BPF_TOKEN_PATH, if both are set at the same time. Setting bpf_token_path option to empty string disables libbpf’s automatic attempt to create BPF token from default BPF FS mount point (/sys/fs/bpf), in case this default behavior is undesirable.

Implementations

impl LibbpfOpts

pub fn into_bpf_open_opts(self) -> Option<bpf_object_open_opts>

Helper method to convert LibbpfOpts into an Option<bpf_object_open_opts>.

Returns Some(bpf_object_open_opts) if any field in LibbpfOpts is set, otherwise returns None.
