src/lib/librumphijack: hijack.c rumphijack.3
Log Message:
Add ``blanket''. It acts like path, except that the prefix does
_not_ get removed if the call goes to the rump namespace.
So, now it's possible to use e.g. tcpdump (and most other utilities
which hardcore a /dev pathname) on a rump kernel:
golem> setenv RUMPHIJACK blanket=/dev/bpf
golem> tcpdump -n -i virt0
tcpdump: WARNING: SIOCGIFADDR: virt0: Device not configured
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on virt0, link-type EN10MB (Ethernet), capture size 96 bytes

seq 0, length 64
21:55:39.095596 IP 204.152.190.12 > 192.168.2.101: ICMP echo reply, id 47811,
seq 0, length 64
(if you additionally set socket=all in RUMPHIJACK, tcpdump doesn't
whine about the "not configured" interface)
