* udp: introduce sk_for_each_rcu_safenext()Eric Dumazet2008-10-29
| | | | | | | | | | | | | | | | | | | | Corey Minyard found a race added in commit 271b72c7fa82c2c7a795bc16896149933110672d (udp: RCU handling for Unicast packets.) "If the socket is moved from one list to another list in-between the time the hash is calculated and the next field is accessed, and the socket has moved to the end of the new list, the traversal will not complete properly on the list it should have, since the socket will be on the end of the new list and there's not a way to tell it's on a new list and restart the list traversal. I think that this can be solved by pre-fetching the "next" field (with proper barriers) before checking the hash." This patch corrects this problem, introducing a new sk_for_each_rcu_safenext() macro. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* udp: calculate udp_mem based on low memory instead of all memoryEric Dumazet2008-10-29
| | | | | | | | | | | | This patch mimics commit 57413ebc4e0f1e471a3b4db4aff9a85c083d090e (tcp: calculate tcp_mem based on low memory instead of all memory) The udp_mem array which contains limits on the total amount of memory used by UDP sockets is calculated based on nr_all_pages. On a 32 bits x86 system, we should base this on the number of lowmem pages. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* udp: RCU handling for Unicast packets.Eric Dumazet2008-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Goals are : 1) Optimizing handling of incoming Unicast UDP frames, so that no memory writes should happen in the fast path. Note: Multicasts and broadcasts still will need to take a lock, because doing a full lockless lookup in this case is difficult. 2) No expensive operations in the socket bind/unhash phases : - No expensive synchronize_rcu() calls. - No added rcu_head in socket structure, increasing memory needs, but more important, forcing us to use call_rcu() calls, that have the bad property of making sockets structure cold. (rcu grace period between socket freeing and its potential reuse make this socket being cold in CPU cache). David did a previous patch using call_rcu() and noticed a 20% impact on TCP connection rates. Quoting Cristopher Lameter : "Right. That results in cacheline cooldown. You'd want to recycle the object as they are cache hot on a per cpu basis. That is screwed up by the delayed regular rcu processing. We have seen multiple regressions due to cacheline cooldown. The only choice in cacheline hot sensitive areas is to deal with the complexity that comes with SLAB_DESTROY_BY_RCU or give up on RCU." - Because udp sockets are allocated from dedicated kmem_cache, use of SLAB_DESTROY_BY_RCU can help here. Theory of operation : --------------------- As the lookup is lockfree (using rcu_read_lock()/rcu_read_unlock()), special attention must be taken by readers and writers. Use of SLAB_DESTROY_BY_RCU is tricky too, because a socket can be freed, reused, inserted in a different chain or in worst case in the same chain while readers could do lookups in the same time. In order to avoid loops, a reader must check each socket found in a chain really belongs to the chain the reader was traversing. If it finds a mismatch, lookup must start again at the begining. This *restart* loop is the reason we had to use rdlock for the multicast case, because we dont want to send same message several times to the same socket. We use RCU only for fast path. Thus, /proc/net/udp still takes spinlocks. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* udp: introduce struct udp_table and multiple spinlocksEric Dumazet2008-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UDP sockets are hashed in a 128 slots hash table. This hash table is protected by *one* rwlock. This rwlock is readlocked each time an incoming UDP message is handled. This rwlock is writelocked each time a socket must be inserted in hash table (bind time), or deleted from this table (close time) This is not scalable on SMP machines : 1) Even in read mode, lock() and unlock() are atomic operations and must dirty a contended cache line, shared by all cpus. 2) A writer might be starved if many readers are 'in flight'. This can happen on a machine with some NIC receiving many UDP messages. User process can be delayed a long time at socket creation/dismantle time. This patch prepares RCU migration, by introducing 'struct udp_table and struct udp_hslot', and using one spinlock per chain, to reduce contention on central rwlock. Introducing one spinlock per chain reduces latencies, for port randomization on heavily loaded UDP servers. This also speedup bindings to specific ports. udp_lib_unhash() was uninlined, becoming to big.

* netns: Coexist with the sysfs limitations v2Eric W. Biederman2008-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | To make testing of the network namespace simpler allow the network namespace code and the sysfs code to be compiled and run at the same time. To do this only virtual devices are allowed in the additional network namespaces and those virtual devices are not placed in the kobject tree. Since virtual devices don't actually do anything interesting hardware wise that needs device management there should be no loss in keeping them out of the kobject tree and by implication sysfs. The gain in ease of testing and code coverage should be significant.

* net: implement emergency route cache rebulds when gc_elasticity is exceededNeil Horman2008-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch to provide on demand route cache rebuilding. Currently, our route cache is rebulid periodically regardless of need. This introduced unneeded periodic latency. This patch offers a better approach. Using code provided by Eric Dumazet, we compute the standard deviation of the average hash bucket chain length while running rt_check_expire. Should any given chain length grow to larger that average plus 4 standard deviations, we trigger an emergency hash table rebuild for that net namespace. This allows for the common case in which chains are well behaved and do not grow unevenly to not incur any latency at all, while those systems (which may be being maliciously attacked), only rebuild when the attack is detected. This patch take 2 other factors into account: 1) chains with multiple entries that differ by attributes that do not affect the hash value are only counted once, so as not to unduly bias system to rebuilding if features like QOS are heavily used 2) if rebuilding crosses a certain threshold (which is adjustable via the added sysctl in this patch), route caching is disabled entirely for that net namespace, since constant rebuilding is less efficient that no caching at all Tested successfully by me.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This optimizes firewire-sbp2's device probe for the case that the local node and the SBP-2 node were discovered at the same time. In this case, fw-core's bus management work and fw-sbp2's login and SCSI probe work are scheduled in parallel (in the globally shared workqueue and in fw-sbp2's workqueue, respectively). The bus reset from fw-core may then disturb and extremely delay the login and SCSI probe because the latter fails with several command timeouts and retries and has to be retried from scratch. We avoid this particular situation of sbp2_login() and fw_card_bm_work() running in parallel by delaying the first sbp2_login() a little bit. This is meant to be a short-term fix for https://bugzilla.redhat.com/show_bug.cgi?id=466679. In the long run, the SCSI probe, i.e. fw-sbp2's call of __scsi_add_device(), should be parallelized with sbp2_reconnect(). Problem reported and fix tested and confirmed by Alex Kanavin.
