Alessandro Decina	5f8f18e3a1	aya: loader: take BTF info as reference ... Allows sharing the same BTF info across many loaders	3 years ago
Dave Tucker	9426f36f79	Implement Pinning For Programs and Maps ... This commit adds 2 new methods to aya::sys - bpf_pin_object - bpf_get_object Which allow the pinning and retrieval of programs/maps to bpffs. It adds a `Program.pin` API, such that a loaded program can be pinned. For map pinning, the user must ensure the `pinning u32` in the `bpf_map_def` is set to 1, maps will be pinned using a new builder API. BpfLoader::new().map_pin_path("/sys/fs/bpf/myapp").load_file("myapp.o") This will pin all maps whose definition requests pinning to path + name.

Alessandro Decina	4222b140ec	aya: perf_map: fix bug when max_entries=0 ... When a perf map has max_entries=0, max_entries is dynamically set at load time to the number of possible cpus as reported by /sys/devices/system/cpu/possible. This change fixes a bug where instead of setting max_entries to the number of possible cpus, we were setting it to the cpu index of the last possible cpu.	4 years ago

Alessandro Decina	30d2b25f11	aya: xdp: fix detaching on kernels older than 5.7 ... XDP_FLAGS_REPLACE was added in 5.7. Now for kernels >= 5.7 whenever we detach an XDP program we pass along the program fd we expect to be detaching. For older kernels, we just detach whatever is attached, which is not great but it's the way the API worked pre XDP_FLAGS_REPLACE.	4 years ago
