CVS commit: src/lib/librumphijack

Module Name:    src
Committed By:   pooka
Date:           Tue Mar  8 20:59:02 UTC 2011

Modified Files:
        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
21:55:38.925596 IP > ICMP echo request, id 47811, 
seq 0, length 64
21:55:39.095596 IP > 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)
