2008-01-31[IPV4] route cache: Introduce rt_genid for smooth cache invalidationEric Dumazet
Current ip route cache implementation is not suited to large caches. We can consume a lot of CPU when cache must be invalidated, since we currently need to evict all cache entries, and this eviction is sometimes asynchronous. min_delay & max_delay can somewhat control this asynchronism behavior, but whole thing is a kludge, regularly triggering infamous soft lockup messages. When entries are still in use, this also consumes a lot of ram, filling dst_garbage.list. A better scheme is to use a generation identifier on each entry, so that cache invalidation can be performed by changing the table identifier, without having to scan all entries. No more delayed flushing, no more stalling when secret_interval expires. Invalidated entries will then be freed at GC time (controled by ip_rt_gc_timeout or stress), or when an invalidated entry is found in a chain when an insert is done. Thus we keep a normal equilibrium. This patch : - renames rt_hash_rnd to rt_genid (and makes it an atomic_t) - Adds a new rt_genid field to 'struct rtable' (filling a hole on 64bit) - Checks entry->rt_genid at appropriate places :
2008-01-31[TCP]: Fix a bug in strategy_allowed_congestion_controlShan Wei
In strategy_allowed_congestion_control of the 2.6.24 kernel, when sysctl_string return 1 on success,it should call tcp_set_allowed_congestion_control to set the allowed congestion control.But, it don't. the sysctl_string return 1 on success, otherwise return negative, never return 0.The patch fix the problem.

2008-01-31[IPV4] fib_trie: rescan if key is lost during dumpStephen Hemminger
Normally during a dump the key of the last dumped entry is used for continuation, but since lock is dropped it might be lost. In that case fallback to the old counter based N^2 behaviour. This means the dump will end up skipping some routes which matches what FIB_HASH does. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Typical table module registers xt_table structure (i.e. packet_filter) and link it to list during it. We can't use one template for it because corresponding list_head will become corrupted. We also can't unregister with template because it wasn't changed at all and thus doesn't know in which list it is. So, we duplicate template at the very first step of table registration. Table modules will save it for use during unregistration time and actual filtering. Do it at once to not screw bisection. P.S.: renaming i.e. packet_filter => __packet_filter is temporary until full netnsization of table modules is done.

2008-01-31[TCP]: NewReno must count every skb while marking lossesIlpo Järvinen
NewReno should add cnt per skb (as with FACK) instead of depending on SACKED_ACKED bits which won't be set with it at all. Effectively, NewReno should always exists after the first iteration anyway (or immediately if there's already head in lost_out. This was fixed earlier in net-2.6.25 but got reverted among other stuff and I didn't notice that this is still necessary (actually wasn't even considering this case while trying to figure out the reports because I lived with different kind of code than it in reality was). This should solve the WARN_ONs in TCP code that as a result of this triggered multiple times in every place we check for this invariant.
