Split union RT_gw into separate struct rtentry fields. The union of rt_gwroute and rt_cachecnt makes debugging harder. In theory the RTF_GATEWAY flag distinguishes which field is relevant, but that does not help when hunting bugs and races in this area. The benefit of saving 4 bytes in struct rtentry is minimal. Break up the RT_gw union. To keep memory compact, sort pointers to the beginning and integres to the end of struct rtentry. OK mvs@ |

Grab kenel lock when deleting a route. Shortly before release, it is better to throw a kernel lock around calls to rtrequest_delete(). This function modifies struct rtentry fields documented with exclusive net lock, or shared net lock plus kernel lock. By now TCP timers doing path MTU discovery hold shared net lock only. After 7.7 release we can figure out which fine grained locking is needed. OK mvs@ |
