Updated cpio packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The cpio packages provide the GNU cpio file archiver utility. GNU cpio can be used to copy and extract files into or from cpio and Tar archives. This update is related to the following bug:
Prior to this update, the cpio man page did not document how to use tape devices that do not use the default block size of 512 bytes for I/O operations. As a result, the cpio utility could fail with the error message "cpio: read error: Cannot allocate memory" if another block size was used. With this update, the man page states that setting the block size with the "--block-size" long option avoids this problem.
All users of cpio are advised to upgrade to these updated packages, which fix this bug.
