The Design and Implementation of the Anykernel and Rump Kernels

RUMPHIJACK(3) NetBSD Library Functions Manual RUMPHIJACK(3)
while ‘‘all:noinet’’ specifies that all protocol families
except PF_INET should be hijacked.
‘‘vfs’’
The specifier value contains a colon-separated list
of which vfs-related system calls should be hijacked.
These differ from the pathname-based file system
syscalls in that there is no pathname to make the
selection based on. Current possible values are
‘‘nfssvc’’, ‘‘getvfsstat’’, and ‘‘fhcalls’’. They
indicate hijacking nfssvc(), getvfsstat(), and all
file handle calls, respectively. The file handle
calls include fhopen(), fhstat(), and fhstatvfs1().
It is also possible to use ‘‘all’’ and ‘‘no’’ in the
same fashion as with the socket hijack specifier.
‘‘sysctl’’
Direct the __sysctl() backend of the sysctl(3) facility
to the rump kernel. Acceptable values are
‘‘yes’’ and ‘‘no’’, meaning to call the rump or the
host kernel, respectively.
‘‘fdoff’’
Adjust the library’s fd offset to the specified
value. All rump kernel descriptors have the offset
added to them before they are returned to the application.
This should be changed only if the application
defines a low non-default FD_SETSIZE for
select() or if it opens a very large number of file
descriptors. The default value is 128.
If the environment variable is unset, the default value
"path=/rump,socket=all:nolocal" is used. The rationale for this
