If the caller gives "/vicep" or "vicep" to volutil_GetPartitionID(), we'll strlcpy() an empty string into ascii[], setting ascii[0] to 0. Then we check the value of ascii[1], which is uninitialized. This doesn't result in any bad behavior, because we then immediately check the value of ascii[0] (which is 0), and return -1. But reading the uninitialized ascii[1] triggers errors in tools like valgrind, and is possibly fragile for future code changes. To avoid this, make sure ascii[] is initialized at the start of the function, and check if we have copied an empty string into ascii[]. While we are here, also add tests in volutil-t for invalid "vicep*" strings, to match the existing tests for invalid "/vicep*" strings.

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.
