7e7c1896a0 Sometimes, depending on the bpf filter rules used in $PATTERN,
the example script of the manpage feeds awk(1) with values larger
than UINT32_MAX.  Then awk prints a negative value, and this
messes up $BPFPROG.  Trying to load the resulting bpf byte codes
with ngctl then fails.

For example, the output for PATTERN="udp and dst net 255.255.0.0/16"
should be (all in one line):

    bpf_prog_len=10
    bpf_prog=[
      { code=40 jt=0 jf=0 k=12 }
      { code=21 jt=7 jf=0 k=34525 }
      { code=21 jt=0 jf=6 k=2048 }
      { code=48 jt=0 jf=0 k=23 }
      { code=21 jt=0 jf=4 k=17 }
      { code=32 jt=0 jf=0 k=30 }
      { code=84 jt=0 jf=0 k=4294901760 }
      { code=21 jt=0 jf=1 k=4294901760 }
      { code=6 jt=0 jf=0 k=8192 }
      { code=6 jt=0 jf=0 k=0 }
    ]

The two k=4294901760 values are displayed as k=-2147483648 by awk.

Replace the awk script of the manpage example with a slower but
safer version, that doesn't really attempt to convert the byte
code printed by tcpdump from string to number and back.

89624a3490 Replace all uses of the old netgraph constants NG_*LEN by the new
constants NG_*SIZ that include the trailing NUL byte. This change
is mostly mechanical except for the replacement of a couple of snprintf()
and sprintf() calls with strlcpy.

c1f3e4bf21 Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

92a3e5521f New netgraph node type, ng_bpf(8). This node type allows you to
apply bpf(4) filters to data travelling through a netgraph network.
