An updated module-init-tools package that fixes two bugs and adds one enhancement is now available for Red Hat Enterprise Linux 6.
The module-init-tools package includes various programs needed for automatic loading and unloading of modules under 2.6 and later kernels, as well as other module management programs. Device drivers and file systems are two examples of loaded and unloaded modules.
Previously, if the "override" keyword was present in the depmod.conf file without any parameters specified, the depmod utility terminated unexpectedly with a segmentation fault. A patch has been applied to ensure that the depmod utility no longer crashes and a syntax warning is displayed instead.
Previously, on low-memory systems (such as low-memory high-performance infrastructure, or HPC, nodes or virtual machines), depmod could use excessive amount of memory. As a consequence, the depmod process was killed by the OOM (out of memory) mechanism, and the system was unable to boot. With this update, the free() function is correctly used on several places in the code so that so that depmod's memory consumption is reduced.
This update adds the "backports" directory to the search path in the depmod.conf file, which is necessary to support integration of the compat-wireless package into kernel packages.
All users of module-init-tools are advised to upgrade to this updated package, which fixes these bugs and adds this enhancement.
