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
