From 8f6ed30d57969451cf6dee44963bdbfad19bea01 Mon Sep 17 00:00:00 2001 From: dholland Date: Fri, 19 Nov 2010 06:44:33 +0000 Subject: Introduce struct pathbuf. This is an abstraction to hold a pathname and the metadata required to interpret it. Callers of namei must now create a pathbuf and pass it to NDINIT (instead of a string and a uio_seg), then destroy the pathbuf after the namei session is complete. Update all namei call sites accordingly. Add a pathbuf(9) man page and update namei(9). The pathbuf interface also now appears in a couple of related additional places that were passing string/uio_seg pairs that were later fed into NDINIT. Update other call sites accordingly. --- sys/dev/dm/dm_pdev.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'sys/dev/dm/dm_pdev.c') diff --git a/sys/dev/dm/dm_pdev.c b/sys/dev/dm/dm_pdev.c index 250624898f2..7f63a463691 100644 --- a/sys/dev/dm/dm_pdev.c +++ b/sys/dev/dm/dm_pdev.c @@ -1,4 +1,4 @@ -/* $NetBSD: dm_pdev.c,v 1.6 2010/01/04 00:19:08 haad Exp $ */ +/* $NetBSD: dm_pdev.c,v 1.7 2010/11/19 06:44:40 dholland Exp $ */ /* * Copyright (c) 2008 The NetBSD Foundation, Inc. @@ -84,6 +84,7 @@ SLIST_HEAD(dm_pdevs, dm_pdev) dm_pdev_list; dm_pdev_t * dm_pdev_insert(const char *dev_name) { + struct pathbuf *dev_pb; dm_pdev_t *dmp; int error; @@ -103,7 +104,15 @@ dm_pdev_insert(const char *dev_name) if ((dmp = dm_pdev_alloc(dev_name)) == NULL) return NULL; - error = dk_lookup(dev_name, curlwp, &dmp->pdev_vnode, UIO_SYSSPACE); + dev_pb = pathbuf_create(dev_name); + if (dev_pb == NULL) { + aprint_debug("pathbuf_create on device: %s failed!\n", + dev_name); + kmem_free(dmp, sizeof(dm_pdev_t)); + return NULL; + } + error = dk_lookup(dev_pb, curlwp, &dmp->pdev_vnode); + pathbuf_destroy(dev_pb); if (error) { aprint_debug("dk_lookup on device: %s failed with error %d!\n", dev_name, error); -- cgit
