Re: NPF sljit error



Hi , Alexsander.

Sorry for this question.

Default XEN_DOMU kernel does not include the MODULAR option.
I add this option ,  options MODULAR ,  and is now working.
For npflog , do you have any rc script?

Thank you for your interest

Hi Siyar,

It's hard to understand from your email what is your config and what
exactly went wrong. I'll try but I may take a completely different
path.

I don't have 'npf' on my base NetBSD system. Is it from pkgsrc?

This is just a warning. Are you sure it's a problem?

Try loading sljit and bpfjit modules and enabling jit:

root# modload sljit
root# modload bpfjit
root# sysctl -w net.bpf.jit=1

These changes can be made permanent with these two commands:

root# cat <<EOF >> /etc/modules.conf
sljit
bpfjit
EOF

root# cat <<EOF > /etc/sysctl.conf
net.bpf.jit=1
EOF

Are you running as root?

It's doesn't look like a well-formed error message.

It compiles on amd64-current. You rarely need to compile your own
kernel, though, because bpfjit and sljit are compiled as builtin
modules if MKSLJIT=yes (it's yes by default on amd64, i386 and sparc).

Please send the command you run and the message you get.

Avoid building your own kernel. Try loading the modules or running
without jit.
