Updated libpcap packages that fix one bug are now available for Red Hat Enterprise Linux 6.
Libpcap provides a portable framework for low-level network monitoring. Libpcap can provide network statistics collection, security monitoring and network debugging.
- BZ#1025841, BZ#1063328
- Previously, running the "tcpdump" command with the filter expression containing the keyword "vlan" produced unexpected output, as the filter generated by the libpcap Berkeley Packet Filter (BPF) compiler did not employ BPF extensions. To fix this bug, libpcap has been amended and now generates filters that use BPF extensions when appropriate. As a result, running "tcpdump" with filters containing "vlan" produces correct results.
Users of libpcap are advised to upgrade to these updated packages, which fix this bug.
