OrangeFS accepts a mask indicating which attributes were changed. The kernel must not set any bits except those that were actually changed. The kernel must set the uid/gid of the request to the actual uid/gid responsible for the change. Code path for notify_change initiated setattrs is orangefs_setattr(dentry, iattr) -> __orangefs_setattr(inode, iattr) In kernel changes are initiated by calling __orangefs_setattr. Code path for writeback is orangefs_write_inode -> orangefs_inode_setattr attr_valid and attr_uid and attr_gid change together under i_lock. I_DIRTY changes separately. __orangefs_setattr lock if needs to be cleaned first, unlock and retry set attr_valid copy data in unlock mark_inode_dirty orangefs_inode_setattr lock copy attributes out unlock clear getattr_time # __writeback_single_inode clears dirty orangefs_inode_getattr # possible to get here with attr_valid set and not dirty lock if getattr_time ok or attr_valid set, unlock and return unlock do server operation # another thread may getattr or setattr, so check for that lock if getattr_time ok or attr_valid, unlock and return else, copy in update getattr_time unlock Signed-off-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com> |
