[OmniOS-discuss] otherwise stable system sudden crashing

[Dan McDonald]

There were some SMB updates in r151016.

There are even BIGGER ones that landed in illumos just after 016 closed, so I don't have a handy reference from upstream.

Looking at '016, your problem is likely in a function whose frame isn't in your dump:  smb_sign_begin().  There are two potential bcopy() calls there, and one of them is calling with a NULL pointer.

        bcopy(token->tkn_session_key, sign->mackey, SSN_KEY_LEN);
        if (sinfo->ssi_cspwlen > 0) {
                bcopy(sinfo->ssi_cspwd, sign->mackey + SSN_KEY_LEN,
                    sinfo->ssi_cspwlen);
        }

I'm not sure which of those two gets called.

Having said that, I'm not sure how much help I can get or give you without an actual coredump to inspect.
