From: miod Date: Wed, 14 Jan 2015 19:01:00 +0000 (+0000) Subject: Remove pass-through ioctl for SMD disks (DIOSXDCMD). Nothing uses this, because X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=69907ce7d23aa793630bf69d7054d65c138b10f9;p=openbsd Remove pass-through ioctl for SMD disks (DIOSXDCMD). Nothing uses this, because noone wrote an equivalent of SunOS format(8) and noone ever will. --- diff --git a/sys/arch/sparc/dev/xd.c b/sys/arch/sparc/dev/xd.c index 0d4153f81f0..b7026d86b48 100644 --- a/sys/arch/sparc/dev/xd.c +++ b/sys/arch/sparc/dev/xd.c @@ -1,4 +1,4 @@ -/* $OpenBSD: xd.c,v 1.64 2015/01/13 20:40:11 miod Exp $ */ +/* $OpenBSD: xd.c,v 1.65 2015/01/14 19:01:00 miod Exp $ */ /* $NetBSD: xd.c,v 1.37 1997/07/29 09:58:16 fair Exp $ */ /* @@ -81,7 +81,6 @@ #include #include -#include #include #include @@ -208,7 +207,6 @@ int xdc_cmd(struct xdc_softc *, int, int, int, int, int, char *, int); char *xdc_e2str(int); int xdc_error(struct xdc_softc *, struct xd_iorq *, struct xd_iopb *, int, int); -int xdc_ioctlcmd(struct xd_softc *, dev_t dev, struct xd_iocmd *); void xdc_perror(struct xd_iorq *, struct xd_iopb *, int); int xdc_piodriver(struct xdc_softc *, int, int); int xdc_remove_iorq(struct xdc_softc *); @@ -815,7 +813,6 @@ xdioctl(dev, command, addr, flag, p) { struct xd_softc *xd; - struct xd_iocmd *xio; int error, s, unit; unit = DISKUNIT(dev); @@ -869,12 +866,6 @@ xdioctl(dev, command, addr, flag, p) } return error; - case DIOSXDCMD: - xio = (struct xd_iocmd *) addr; - if ((error = suser(p, 0)) != 0) - return (error); - return (xdc_ioctlcmd(xd, dev, xio)); - default: return ENOTTY; } @@ -2123,137 +2114,6 @@ xdc_tick(arg) timeout_add(&xdcsc->xdc_tick_tmo, XDC_TICKCNT); } -/* - * xdc_ioctlcmd: this function provides a user level interface to the - * controller via ioctl. this allows "format" programs to be written - * in user code, and is also useful for some debugging. we return - * an error code. called at user priority. - */ -int -xdc_ioctlcmd(xd, dev, xio) - struct xd_softc *xd; - dev_t dev; - struct xd_iocmd *xio; - -{ - int s, err, rqno, dummy; - caddr_t dvmabuf = NULL, buf = NULL; - struct xdc_softc *xdcsc; - - /* check sanity of requested command */ - - switch (xio->cmd) { - - case XDCMD_NOP: /* no op: everything should be zero */ - if (xio->subfn || xio->dptr || xio->dlen || - xio->block || xio->sectcnt) - return (EINVAL); - break; - - case XDCMD_RD: /* read / write sectors (up to XD_IOCMD_MAXS) */ - case XDCMD_WR: - if (xio->subfn || xio->sectcnt > XD_IOCMD_MAXS || - xio->sectcnt * XDFM_BPS != xio->dlen || xio->dptr == NULL) - return (EINVAL); - break; - - case XDCMD_SK: /* seek: doesn't seem useful to export this */ - return (EINVAL); - - case XDCMD_WRP: /* write parameters */ - return (EINVAL);/* not useful, except maybe drive - * parameters... but drive parameters should - * go via disklabel changes */ - - case XDCMD_RDP: /* read parameters */ - if (xio->subfn != XDFUN_DRV || - xio->dlen || xio->block || xio->dptr) - return (EINVAL); /* allow read drive params to - * get hw_spt */ - xio->sectcnt = xd->hw_spt; /* we already know the answer */ - return (0); - break; - - case XDCMD_XRD: /* extended read/write */ - case XDCMD_XWR: - - switch (xio->subfn) { - - case XDFUN_THD:/* track headers */ - if (xio->sectcnt != xd->hw_spt || - (xio->block % xd->nsect) != 0 || - xio->dlen != XD_IOCMD_HSZ * xd->hw_spt || - xio->dptr == NULL) - return (EINVAL); - xio->sectcnt = 0; - break; - - case XDFUN_FMT:/* NOTE: also XDFUN_VFY */ - if (xio->cmd == XDCMD_XRD) - return (EINVAL); /* no XDFUN_VFY */ - if (xio->sectcnt || xio->dlen || - (xio->block % xd->nsect) != 0 || xio->dptr) - return (EINVAL); - break; - - case XDFUN_HDR:/* header, header verify, data, data ECC */ - return (EINVAL); /* not yet */ - - case XDFUN_DM: /* defect map */ - case XDFUN_DMX:/* defect map (alternate location) */ - if (xio->sectcnt || xio->dlen != XD_IOCMD_DMSZ || - (xio->block % xd->nsect) != 0 || xio->dptr == NULL) - return (EINVAL); - break; - - default: - return (EINVAL); - } - break; - - case XDCMD_TST: /* diagnostics */ - return (EINVAL); - - default: - return (EINVAL);/* ???
