From f696a3659fc4b3a3bf4bc83d9dbec5e5a2ffd929 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Thu, 31 Jul 2008 13:41:58 +0200 Subject: [PATCH] move executable checking into ->permission() For execute permission on a regular files we need to check if file has any execute bits at all, regardless of capabilites. This check is normally performed by generic_permission() but was also added to the case when the filesystem defines its own ->permission() method. In the latter case the filesystem should be responsible for performing this check. Move the check from inode_permission() inside filesystems which are not calling generic_permission(). Create a helper function execute_ok() that returns true if the inode is a directory or if any execute bits are present in i_mode. Also fix up the following code: - coda control file is never executable - sysctl files are never executable - hfs_permission seems broken on MAY_EXEC, remove - hfsplus_permission is eqivalent to generic_permission(), remove Signed-off-by: Miklos Szeredi --- fs/hfs/inode.c | 8 -------- 1 file changed, 8 deletions(-) (limited to 'fs/hfs') diff --git a/fs/hfs/inode.c b/fs/hfs/inode.c index 7e19835efa2..c69b7ac75bf 100644 --- a/fs/hfs/inode.c +++ b/fs/hfs/inode.c @@ -511,13 +511,6 @@ void hfs_clear_inode(struct inode *inode) } } -static int hfs_permission(struct inode *inode, int mask) -{ - if (S_ISREG(inode->i_mode) && mask & MAY_EXEC) - return 0; - return generic_permission(inode, mask, NULL); -} - static int hfs_file_open(struct inode *inode, struct file *file) { if (HFS_IS_RSRC(inode)) @@ -616,7 +609,6 @@ static const struct inode_operations hfs_file_inode_operations = { .lookup = hfs_file_lookup, .truncate = hfs_file_truncate, .setattr = hfs_inode_setattr, - .permission = hfs_permission, .setxattr = hfs_setxattr, .getxattr = hfs_getxattr, .listxattr = hfs_listxattr, -- cgit v1.2.3-70-g09d2
