函数名称：smack_inode_removexattr - Smack check on removexattr*@dentry: the object*@name: name of the attribute* Removing the Smack attribute requires CAP_MAC_ADMIN* Returns 0 if access is permitted, an error code otherwise

函数原型：static int smack_inode_removexattr(struct dentry *dentry, const char *name)

返回类型：int

参数：

类型参数名称
struct dentry *dentry
const char *name
1380  rc等于0
1382  如果字符串比较恒等于0或字符串比较恒等于0或字符串比较恒等于0或字符串比较恒等于0或字符串比较恒等于0或字符串比较恒等于0则
1388  如果非smack_privileged(Allow MAC configuration or state changes)则rc等于负EPERM
1390  否则rc等于ap_inode_removexattr - Determine whether an xattr may be removed*@dentry: The inode/dentry being altered*@name: The name of the xattr to be changed* Determine whether an xattr may be removed from an inode, returning 0 if
1393  如果rc不等于0则返回:rc
1396  some inline functions to set up audit data* they do nothing if CONFIG_AUDIT is not set
1397  smk_ad_setfield_u_fs_path_dentry( & ad, dentry)
1399  rc等于smk_curacc - determine if current has a specific access to an object*@obj_known: a pointer to the object's Smack label entry*@mode: the access requested, in "MAY" format*@a : common audit data* This function checks the current subject label/object label
1400  rc等于smk_bu_inode(d_backing_inode - Get upper or lower inode we should be using*@upper: The upper layer* This is the helper that should be used to get at the inode that will be used* if this dentry were to be opened as a file. The inode may be on the upper, MAY_WRITE, rc)
1401  如果rc不等于0则返回:rc
1404  isp等于smack_inode(d_backing_inode - Get upper or lower inode we should be using*@upper: The upper layer* This is the helper that should be used to get at the inode that will be used* if this dentry were to be opened as a file. The inode may be on the upper)

1411  sbp等于 The root of the dentry tree
1412  sbsp等于s_security
1414  label of the fso 等于smk_default
1415  否则如果字符串比较恒等于0则label of the task = NULL
1417  否则如果字符串比较恒等于0则label of the mmap domain = NULL
1419  否则如果字符串比较恒等于0则smack inode flags 与等于directory is transmuting 的反
