rwatson 2002/08/11 18:54:11 PDT Modified files: sys/sys vnode.h Log: Introduce IO_NOMACCHECK, a flag that will be passed to vn_rdwr() to indicate that the calling code has already performed necessary MAC checks (if any) for this operation. This flag will help resolve layering problems that existing because vn_rdwr() is called both on behalf of user processes directly (such as in system calls of various sorts, during core dumps, etc), as well as deep in the file system code on behalf of the file system (such as in UFS, ext2fs, etc). Code that is acting on behalf of a kernel service rather than explicitly on behalf of a user process will specify this flag. By default, MAC checks will be performed (and generally should be performed).
