VOP_SETACL(9) BSD Kernel Developer's Manual VOP_SETACL(9) NAME VOP_SETACL -- set the access control list for a vnode SYNOPSIS #include <sys/param.h> #include <sys/vnode.h> #include <sys/acl.h> int VOP_SETACL(struct vnode *vp, acl_type_t type, struct acl *aclp, struct ucred *cred, struct thread *td); DESCRIPTION This vnode call may be used to set the access control list (ACL) for a file or directory. Its arguments are: vp The vnode of the file or directory. type The type of ACL to set. aclp A pointer to an ACL structure from which to retrieve the ACL data. cred The user credentials to use in authorizing the request. td The thread setting the ACL. The aclp pointer may be NULL to indicate that the specified ACL should be deleted. The cred pointer may be NULL to indicate that access control checks are not to be performed, if possible. This cred setting might be used to al- low the kernel to authorize ACL changes that the active process might not be permitted to make. The vnode ACL interface defines the syntax, and not semantics, of file and directory ACL interfaces. More information about ACL management in kernel may be found in acl(9). LOCKS The vnode will be locked on entry and should remain locked on return. RETURN VALUES If the ACL is successfully set, then zero is returned. Otherwise, an ap- propriate error code is returned. ERRORS [EINVAL] The ACL type passed is invalid for this vnode, or the ACL data is invalid. [EACCES] The caller does not have the appropriate privilege. [ENOMEM] Sufficient memory is not available to fulfill the re- quest. [EOPNOTSUPP] The file system does not support VOP_SETACL(). [ENOSPC] The file system is out of space. [EROFS] The file system is read-only. SEE ALSO acl(9), vnode(9), VOP_ACLCHECK(9), VOP_GETACL(9) AUTHORS This manual page was written by Robert Watson. BSD December 23, 1999 BSD
