Unfortunately in my haste to verify this, I bungled my test of -55 and managed to pull down the wrong source for -55 as well. Now that I have corrected both those mistakes, I can verify that the code for the fix is in -55 and the code for the fix functions properly. Sorry about that.....

An example: $ ip route show default via 172.16.231.2 dev eth0 metric 100 172.16.231.0/24 dev eth0 proto kernel scope link src 172.16.231.26 $ ip route show cache local 172.16.231.26 from 172.16.231.1 dev lo src 172.16.231.26 cache <local,src-direct> iif eth0 172.16.231.1 from 172.16.231.26 dev eth0 cache ipid 0xa13f $ ip route change 172.16.231.0/24 dev eth0 proto kernel scope link src 172.16.231.26 initcwnd lock 100 $ ip route show default via 172.16.231.2 dev eth0 metric 100 172.16.231.0/24 dev eth0 proto kernel scope link src 172.16.231.26 initcwnd lock 100 $ ip route show cache 172.16.231.1 from 172.16.231.26 dev eth0 cache ipid 0xa13f rtt 4ms rttvar 4ms cwnd 40 local 172.16.231.26 from 172.16.231.1 dev lo src 172.16.231.26 cache <local,src-direct> iif eth0 Note that the initcwnd metric is not being inherited by the cache entry for 172.16.231.1. The problem is that the inetpeer cache is not flushed when the "ip route change" occurs. Without this the metrics in the inetpeer are used to build the metrics of the route cache entry even though they are stale. A fix for this bug is in the 3.5.0 kernel from quantal. It is a simple fix and could be easily applied to the 3.2.0 line of kernels. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
