	Add another column to the /sys/fs/bpf/maps.debug iterator to display cur_entries, the current number of entries in the map as is returned by the bpf_map_sum_elem_count kfunc. Also fix formatting. Example: # cat /sys/fs/bpf/maps.debug id name max_entries cur_entries 2 iterator.rodata 1 0 125 cilium_auth_map 524288 666 126 cilium_runtime_ 256 0 127 cilium_signals 32 0 128 cilium_node_map 16384 1344 129 cilium_events 32 0 ...

2023-01-28	bpf: iterators: Split iterators.lskel.h into little- and big- endian versions	Ilya Leoshkevich
	iterators.lskel.h is little-endian, therefore bpf iterator is currently broken on big-endian systems. Introduce a big-endian version and add instructions regarding its generation. Unfortunately bpftool's cross-endianness capabilities are limited to BTF right now, so the procedure requires access to a big-endian machine or a configured emulator.
