Currently, the afs_dynroot_addDirEnt() function assumes that the caller has allocated the directory to be large enough to hold the necessary entry. In order to make sure that memory isn't being accidentally stomped, use strlcpy to truncate instead of stomping on other memory. That way, if the caller makes a mistake we don't silently corrupt memory. We specifically do not assert that there is no truncation or panic if truncation occurs, since the effect of a truncated entry in the dynamic AFS root volume is limited and does not justify bringing down the entire client.

AFS is a distributed file system that enables users to share and access all of the files stored in a network of computers as easily as they access the files stored on their local machines. The file system is called distributed for this exact reason: files can reside on many different machines, but are available to users on every machine. OpenAFS 1.0 was originally released by IBM under the terms of the IBM Public License 1.0 (IPL10). For details on IPL10 see the LICENSE file in this directory. The current OpenAFS distribution is licensed under a combination of the IPL10 and many other licenses as granted by the relevant copyright holders. The LICENSE file in this directory contains more details, thought it is not a comprehensive statement. See INSTALL for information about building and installing OpenAFS on various platforms. See CODING for developer information and guidelines. See NEWS for recent changes to OpenAFS.
