$NetBSD: README.dirs,v 1.9 2009/09/04 10:54:44 pooka Exp $ Runnable Userspace Meta Programs Quick rundown of the current directory structure: sys/rump/librump - kernel runtime emulation /rumpkern - kernel core, e.g. syscall, interrupt and lock support /rumpuser - userspace namespace support for rump, *NO* -D_KERNEL provides e.g. malloc() and some syscalls /rumpcrypto - kernel cryptographic routines /rumpdev - device support, e.g. autoconf subsystem /rumpnet - networking support and sockets layer /rumpvfs - file system support sys/rump/include /machine - used for architectures where the rump ABI is not yet the same as the kernel module ABI. will eventually disappear completely /rump - rump headers installed to userspace sys/rump/dev - device components sys/rump/fs - file system components /lib/lib${fs} - kernel file system code compiled out of /sys with -D_KERNEL sys/rump/net - networking components /lib/libnet - subroutines from sys/net, e.g. route and if_ethersubr /lib/libnetinet - TCP/IP /lib/libvirtif - a virtual interface which uses host tap(4) to shovel packets. This is used by netinet and if_ethersubr. /lib/libsockin - implements PF_INET using host kernel sockets. This is mutually exclusive with net, netinet and virtif. Users: src/lib /libp2k - puffs-to-vfs adaption layer, userspace namespace /libukfs - user kernel file system, a library to access file system images (or devices) directly in userspace without going through a system call and puffs src/usr.sbin/puffs rump_$fs - userspace file system daemons using the kernel fs code
