CVE-2009-0778

Created <span class="bz_obsolete"><a href="attachment.cgi?id=331637" name="attach_331637" title="ip_dst_cache (in blue) VS `route -Cn | wc -l` (in green) over time">attachment 331637</a> <a href="attachment.cgi?id=331637&action=edit" title="ip_dst_cache (in blue) VS `route -Cn | wc -l` (in green) over time">[details]</a></span> ip_dst_cache (in blue) VS `route -Cn | wc -l` (in green) over time Description of problem: The value of ip_dst_cache (in /proc/slabinfo) continues to grow constantly, even thought the cached route table remains fairly constant. This leads to the eventual time when ip_dst_cache reaches the value of /proc/sys/net/ipv4/route/max_size. When this happens, the kernel complains with 'dst cache overflow' and the server no longer responds to any network activity. Version-Release number of selected component (if applicable): kernel 2.6.18-92.1.22.el5 How reproducible: live system being currently affected by this issue. Steps to Reproduce: 1. Configure test machine as a router between two networks 2. send packets from network A to network B with a large number of different source/dest IPs 3. Watch the values of ip_dst_cache and rt_cache Actual results: ip_dst_cache continues to grow while rt_cache grows and shrinks with the traffic Expected results: ip_dst_cache and rt_cache follow each other closely. Values return to zero after traffic stops and route cache entries expire. Additional info:
