(I know I shouldn't reply to my own posts)
I traced my last problem to kcapi_ctlr.c
here are my changes starting at line 845
/* check if operation is allowed by owner of the current process /
thread */
if (! curthread ||
curthread->td_ucred == NOCRED || curthread->td_ucred ==
FSCRED ||
suser (curthread) != 0)
{
mtx_unlock (&g_mtxCtlrData);
DBG (LOG_ERROR, "ERROR: Root permission required to reset
controller %u",
uCtlr);
DBG (LOG_ERROR, "ERROR: CIANHHH: User is: %u",
suser (curthread));
if (! curthread) {
DBG (LOG_ERROR, "ERROR: CIANHHH: curthread");
}
if (curthread->td_ucred == NOCRED) {
DBG (LOG_ERROR, "ERROR: CIANHHH: NOCRED");
}
if (curthread->td_ucred == FSCRED ) {
DBG (LOG_ERROR, "ERROR: CIANHHH: FSCRED");
}
uRes = CRE_NO_RIGHTS_TO_RESET;
kcapitrace_appl_reset_ctlr (uCtlr, nNumDataBlocks,
paDataBlocks, uRes);
return (uRes);
}
on boot I got:
kcapimgr: E kcapi_reset_ctlr: ERROR: CIANHHH: User is: 0
kcapimgr: E kcapi_reset_ctlr: ERROR: CIANHHH: NOCRED
Then I removed " curthread->td_ucred == NOCRED || " test, i'm the
only one with access to this box so i'm not to worried about
security, i'll look into why it's failing later.
