I have a simple, probably stupid question. I run FreeBSD 10.4 Stable
r338093 and use the script
#!/usr/sbin/dtrace -s
dtrace:::BEGIN
{
printf("pf_default_rule.timeout[2/16/17]=%d/%d/%d\n",
kernel`pf_default_rule.timeout[2], kernel`pf_default_rule.timeout[16],
kernel`pf_default_rule.timeout[17]);
}
The output normally is
pf_default_rule.timeout[2/16/17]=86400/6000/12000
But when I change the sourcefile /sys/netpfil/pf/pf.c trying a patch and
build and install the new kernel but without reboot, then the output of
the script is wrong:
pf_default_rule.timeout[2/16/17]=3237216124/0/0
After reboot everything works again.
