From f5bebbbb28dc7a149a891f0f1e112fb50bb72664 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 30 Sep 2014 13:59:30 +0200 Subject: util: Emancipate id_wellformed() from QemuOpts IDs have long spread beyond QemuOpts: not everything with an ID necessarily goes through QemuOpts. Commit 9aebf3b is about such a case: block layer names are meant to be well-formed IDs, but some of them don't go through QemuOpts, and thus weren't checked. The commit fixed that the straightforward way: rename the internal QemuOpts helper id_wellformed() to qemu_opts_id_wellformed() and give it external linkage. Instead of using it directly in block.c, the commit adds wrapper bdrv_is_valid_name(), probably to hide the connection to QemuOpts. Go one logical step further: emancipate IDs from QemuOpts. Rename the function back to id_wellformed(), and put it in another file. While there, clean up its value to bool. Peel off the bdrv_is_valid_name() wrapper. [Replaced stray return 0 with return false to match bool returns used elsewhere in id_wellformed(). --Stefan] Signed-off-by: Markus Armbruster Signed-off-by: Stefan Hajnoczi --- block.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) (limited to 'block.c') diff --git a/block.c b/block.c index c5a251c57e..d3aebeb050 100644 --- a/block.c +++ b/block.c @@ -335,18 +335,13 @@ void bdrv_register(BlockDriver *bdrv) QLIST_INSERT_HEAD(&bdrv_drivers, bdrv, list); } -static bool bdrv_is_valid_name(const char *name) -{ - return qemu_opts_id_wellformed(name); -} - /* create a new block device (by default it is empty) */ BlockDriverState *bdrv_new(const char *device_name, Error **errp) { BlockDriverState *bs; int i; - if (*device_name && !bdrv_is_valid_name(device_name)) { + if (*device_name && !id_wellformed(device_name)) { error_setg(errp, "Invalid device name"); return NULL; } @@ -874,7 +869,7 @@ static void bdrv_assign_node_name(BlockDriverState *bs, } /* Check for empty string or invalid characters */ - if (!bdrv_is_valid_name(node_name)) { + if (!id_wellformed(node_name)) { error_setg(errp, "Invalid node name"); return; } -- cgit 1.4.1
