Name:Check whether a task can use an open file descriptor toaccess an inode in a given way. Check access to thedescriptor itself, and then use dentry_has_perm tocheck a particular permission to the file.Access to the descriptor is implicitly granted if it
Proto:static int file_has_perm(const struct cred *cred, struct file *file, unsigned int av)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
const struct cred * | cred | |
struct file * | file | |
unsigned int | av |
1748 | fsec = selinux_file(file) |
1749 | inode = file_inode(file) |
1754 | type = LSM_AUDIT_DATA_FILE |
1757 | If sid != SID of open file description Then |
1774 | rc = 0 |
1775 | If av Then rc = Check whether a task has a particular permission to an inode.The 'adp' parameter is optional and allows other auditdata to be passed (e.g. the dentry). |
