3 Runnable Userspace Meta Programs
5 Quick rundown of the current directory structure:
7 sys/rump/librump - kernel runtime emulation
8 /rumpkern - kernel core, e.g. syscall, interrupt and lock support
9 /rumpuser - userspace namespace support for rump, *NO* -D_KERNEL
10 provides e.g. malloc() and some syscalls
12 /rumpcrypto - kernel cryptographic routines
13 /rumpdev - device support, e.g. autoconf subsystem
14 /rumpnet - networking support and sockets layer
15 /rumpvfs - file system support
18 /machine - used for architectures where the rump ABI is not yet the
19 same as the kernel module ABI. will eventually disappear
21 /rump - rump headers installed to userspace
23 sys/rump/dev - device components
25 sys/rump/fs - file system components
26 /lib/lib${fs} - kernel file system code compiled out of /sys with -D_KERNEL
28 sys/rump/net - networking components
29 /lib/libnet - subroutines from sys/net, e.g. route and if_ethersubr
30 /lib/libnetinet - TCP/IP
31 /lib/libvirtif - a virtual interface which uses host tap(4) to shovel
32 packets. This is used by netinet and if_ethersubr.
33 /lib/libsockin - implements PF_INET using host kernel sockets. This is
34 mutually exclusive with net, netinet and virtif.
38 /libp2k - puffs-to-vfs adaption layer, userspace namespace
39 /libukfs - user kernel file system, a library to access file system
40 images (or devices) directly in userspace without going
41 through a system call and puffs
44 rump_$fs - userspace file system daemons using the kernel fs code
