Alessandro Decina	2cec04c578	bpf: add explicit BTF argument to the load API ... Add a `target_btf: Option<Btf>` argument to Bpf::load. None can be passed to indicate to skip BTF relocation, for example for kernels that don't support it. Some(btf) can be used to pass BTF parsed with Btf::from_sys_fs() or Btf::parse/parse_file. Finally, add a simpler Bpf::load_file(path) that uses from_sys_fs() internally to simplify the common case.	5 years ago

Alessandro Decina	fdc4dad5ff	maps: add AsyncPerfMap ... When the async_tokio or async_std features are enabled, AsyncPerfMap provides an async version of PerfMap which returns a future from read_events()	5 years ago
Alessandro Decina	4be0c45305	perf_map: split in sub modules	5 years ago

Alessandro Decina	d4e282535b	bpf, perf_map: make maps usable from multiple threads ... Change PerfMap API so that individual buffers can be read from multiple threads. Change the way maps are stored in the `Bpf` struct from RefCell to a custom RwLock.	5 years ago

Alessandro Decina	c110394aaa	xdp: add netlink based implementation for kernels < 5.7 ... bpf_link_create was introduced in linux 5.7, so use netlink to configure XDP on older kernels.	5 years ago

Alessandro Decina	54637eab04	Improve relocation errors ... Use BpfError::RelocationError for both maps and BTF relocations. The error includes the name of the program that failed, and the source error stored as Box<dyn Error>. This hides the implementation details of the source errors - which are unrecoverable anyway - while still allowing fine grained error messages.	5 years ago
Alessandro Decina	37c3a198c4	Rework the error hierarchy ... Add BpfError::IO and BpfError::BtfError and remove the nested IO and BtfError variants inside ParseError and RelocationError	5 years ago

Alessandro Decina	b75efc8efe	bpf: fix loading socket filters from obj files	5 years ago
Alessandro Decina	a8c212377f	bpf: make program() and program_mut() return inner program types ... program() and program_mut() are now generic and can return the inner program type, which is what you want 99.999% of the time, eg: let prog = bpf.program_mut::<&mut Xdp>("foo")?.unwrap(); prog.load()?; prog.attach("eth0")?; The methods will fail if the requested program is not of the expected type (eg if you try to retrieve a kprobe as an xdp program).	5 years ago
Alessandro Decina	4dc01f64dd	bpf: make map() and map_mut() optionally return concrete map types ... map() and map_mut() used to return Ref<Map>, then to convert to a concrete type you had to: let mut perf_map: PerfMap<_> = bpf.map_mut("PERF_MAP").unwrap().try_into()?;; But the base Map type is pretty much only useful internally. This change makes map() and map_mut() use TryInto internally, so that now conversions can can be done with: let mut perf_map: PerfMap<_> = bpf.map_mut("PERF_MAP")?.unwrap();	5 years ago
Alessandro Decina	a41edbca2c	maps: add ProgramArray ... ProgramArray is a wrapper around BPF_MAP_TYPE_PROG_ARRAY maps. Can be used to setup jump tables for bpf_tail_call().	5 years ago
