+++ This bug was initially created as a clone of Bug #677526 +++ Description of problem: port allocation (socket.c ; line 134): used_ports_map[i] |= (1UL << n); - that's going to set a bit port deallocation (socket.c; line 156) : used_ports_map[nr / 32] &= ~((nr % 32) + 1); - that's going to produce garbage [no wonder things don't work] used_ports_map[nr / 32] &= ~(1 << (nr % 32)); or used_ports_map[nr / 32] &= ~(1 << (nr & 0x1f)); - would probably be much better Version-Release number of selected component (if applicable): libnl-1.1-12.fc14.x86_64 libnl-debuginfo-1.1-12.fc14.x86_64 libnl-devel-1.1-12.fc14.x86_64
This bug is causing failures in libvirt's VEPA support in some scenarios (see upstream thread http://www.redhat.com/archives/libvir-list/2011-February/msg00466.html)
This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative.
Dear 'Red Hat Product Management', the correct functioning of other components, i.e., those in libvirt, depend on the correct functioning of libnl. So, we would like to propose this request for RHEL 6.1.
A fix for this bug has been applied and is included in libnl-1.1-14.el6: https://brewweb.devel.redhat.com/buildinfo?buildID=160656
This error: error: internal error failed to get number of interfaces on host (netcf: unspecified error - errors in loading some config files) error:Failed to list active interfaces is unrelated to the libnl problems. It is caused by Bug 690286. You will need to install augeas-0.7.2-6.el6 to eliminate that problem.
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: 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.
