RHBA-2011:0325 - libnl bug fix update
Synopsis
libnl bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated libnl packages that plug a memory leak when libnl reported some error conditions are now available for Red Hat Enterprise Linux 6.
Description
The libnl package contains a convenience library to simplify using the Linux kernel netlink sockets interface for network manipulation.
This update addresses the following issue:
- Some nl_send_auto_complete() callers did not free the allocated message when errors were reported, resulting in libnl leaking memory. A problem in its own right, these small leaks also made it more work to detect memory leaks in other processes. With this update, allocated messages are freed correctly when nl_send_auto_complete() is called, and libnl no longer leaks memory in this circumstance. (BZ#676327)
All libnl users should upgrade to these updated packages, which resolve this issue.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
