1.126. libnl

Updated libnl packages that plug a memory leak when libnl reported some error conditions are now available for Red Hat Enterprise Linux 6.

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.

An updated libnl package that fixes various bugs is now available.

This package contains a convenience library to simplify using the Linux kernel's netlink sockets interface for network manipulation.

This update addresses the following issues:

When a domain started under libvirt, a memory leak was triggered from the libnl library because libnl continued to use memory no longer in use. Memory leaks in libnl are now fixed and libnl releases memory after it completes usage. (BZ#620345)
The port allocation/de-allocation was not safe in multi-threaded applications and the logic was incorrect, which resulted in some applications and other libraries being unable to initialize libnl. Port allocation/de-allocation and logic is now fixed, and libnl can now be initialized. (BZ#677724) (BZ#677725)

All libnl users should upgrade to this updated package, which resolves these issues.
