Notable changes since v22: * ensure local endpoint is copied only if one is specified (compile error)
Notable changes since v21: * accessed crypto_slot->primary_idx via READ/WRITE_ONCE * made ovpn_aead_init() static * converted link tx/rx packet counters from u32 to to uint * ensured all u32 NL attributes are read by nla_get_u32() * ensured all u32 NL attrivutes are written by nla_put_u32() * reset cache upon float or local endpoint change * dropped check for delta > 0 in keepalive worker scheduling * improved comments in update endpoints logic * converted local_ip to void* to avoid useless casts
Please note that some patches were already reviewed/tested by a few people. These patches have retained the tags as they have hardly been touched.
