Description

In the Linux kernel, the following vulnerability has been resolved:

jfs: fix array-index-out-of-bounds read in add_missing_indices

stbl is s8 but it must contain offsets into slot which can go from 0 to
127.

Added a bound check for that error and return -EIO if the check fails.
Also make jfs_readdir return with error if add_missing_indices returns
with an error.
