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
|
|
/rumpnet - networking support and sockets layer
|
|
/rumpuser - userspace namespace support for previous, *NO* -D_KERNEL
|
|
provides e.g. malloc() and some syscalls
|
|
/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/fs - file system rumps
|
|
/lib/lib${fs} - kernel file system code compiled out of /sys with -D_KERNEL
|
|
|
|
sys/rump/net - networking rumps
|
|
/lib/libnet - subroutines from sys/net, e.g. route and if_ethersubr
|
|
/lib/libnetinet - TCP/IP
|
|
/lib/libvirtif - a virtual interface which uses host tap(4) to shovel
|
|
packets. This is used by netinet and if_ethersubr.
|
|
/lib/libsockin - implements PF_INET using host kernel sockets. This is
|
|
mutually exclusive with net, netinet and virtif.
|
|
|
|
Users:
|
|
src/lib
|
|
/libp2k - puffs-to-vfs adaption layer, userspace namespace
|
|
/libukfs - user kernel file system, a library to access file system
|
|
images (or devices) directly in userspace without going
|
|
through a system call and puffs
|
|
|
|
src/usr.sbin/puffs
|
|
rump_$fs - userspace file system daemons using the kernel fs code
