RHBA-2011:0795 - libnl bug fix update


Synopsis

libnl bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

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.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
