[CFT] ng_nptv6 (IPv6-to-IPv6 Network Prefix Translation)

[HIROSHI OOTA]

Hi, all

I have created a netgraph node which performs a IPv6-to-IPv6 Network  
Prefix Translation(RFC6296).

It works with ipfw(ng_ipfw). a sample configuration is follows.

1 setup netgraph
   ngctl mkpeer ipfw: nptv6 1000 inbound
   ngctl name ipfw:1000 nptv6
   ngctl connect ipfw: nptv6: 2000 outbound
   ngctl  msg nptv6: setconfig { inner=fd00:1234:1234::/48  
outer=2001:db8::/32 }

  or use rcng script(ng_nptv6.sh) which is included in archive.
2 setup ipfw
  # inbound
  ipfw 1000 allow ip6 from any to 2001:db8::/64 in
  ipfw 1010 netgraph 1000 ip6 from any to 2001:db8::/32 in
  ipfw 1090 allow ip6 from any to any in
  # outbound
  ipfw 2000 allow ip6 from 2001:db8::/64 to any out
  ipfw 2010 netgraph 2000 ip6 from 2001:db8::/32 to any out
  ipfw 2090 allow ip6 from any to any in

: out of swap space

[HIROSHI OOTA]

Hi all,
my PCEngine's wrap(NanoBSD, i386, 128Mbytes mem, no swap) won't start,  
after updating to r234569.

some of daemons was killed with the message 'out of swap space'.

vmstat in single user mode as:
---  r234568(works fine)

Re: setpgrp(1, 1) does not FAIL

[HIROSHI OOTA]

thanks for your quick fixing. 

but, It should return EPERM instead of ESRCH. Because ESRCH
means `The requested process does not exist'. 

thanks,

setpgrp(1, 1) does not FAIL

[HIROSHI OOTA]

Hello,

The following will succeed in non privilege user.
I think it should fail.

main()
{
   printf("%d\n", setpgrp(1, 1));
}
