The indexGreaterThanIndex function returns the closest index from the
index set that is greater than a specified index. This function is
typically used in a loop to iterate through a list of items until it
returns NSNotFound, indicating the end of the list.
In AFSCommanderPref.m, the following pattern is being used:
int index = 0;
do {
...
} while((index = [... indexGreaterThanIndex:index]) != NSNotFound);
The issue arises because indexGreaterThanIndex returns an NSUInteger,
while the loop uses an int for index. If NSNotFound is cast to an int,
it becomes -1, causing the loop to never terminate and leading to a
crash.
To fix this problem, change the type of index from int to NSUInteger to
ensure proper comparison and termination of the loop when NSNotFound is
returned.

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.
