2008-11-23net: Convert TCP/DCCP listening hash tables to use RCUEric Dumazet
This is the last step to be able to perform full RCU lookups in __inet_lookup() : After established/timewait tables, we add RCU lookups to listening hash table. The only trick here is that a socket of a given type (TCP ipv4, TCP ipv6, ...) can now flight between two different tables (established and listening) during a RCU grace period, so we must use different 'nulls' end-of-chain values for two tables. We define a large value : #define LISTENING_NULLS_BASE (1U << 29) So that slots in listening table are guaranteed to have different end-of-chain values than slots in established table. A reader can still detect it finished its lookup in the right chain. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-20net: listening_hash get a spinlock per bucketEric Dumazet
This patch prepares RCU migration of listening_hash table for TCP/DCCP protocols. listening_hash table being small (32 slots per protocol), we add a spinlock for each slot, instead of a single rwlock for whole table. This should reduce hold time of readers, and writers concurrency. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-16net: Convert TCP & DCCP hash tables to use RCU / hlist_nullsEric Dumazet
RCU was added to UDP lookups, using a fast infrastructure : - sockets kmem_cache use SLAB_DESTROY_BY_RCU and dont pay the price of call_rcu() at freeing time. - hlist_nulls permits to use few memory barriers. This patch uses same infrastructure for TCP/DCCP established and timewait sockets. Thanks to SLAB_DESTROY_BY_RCU, no slowdown for applications using short lived TCP connections. A followup patch, converting rwlocks to spinlocks will even speedup this case. __inet_lookup_established() is pretty fast now we dont have to dirty a contended cache line (read_lock/read_unlock) Only established and timewait hashtable are converted to RCU (bind table and listen table are still using traditional locking) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2008-01-31[INET_DIAG]: Fix inet_diag_lock_handler error path.Arnaldo Carvalho de Melo
Fixes: http://bugzilla.kernel.org/show_bug.cgi?id=9825 The inet_diag_lock_handler function uses ERR_PTR to encode errors but its callers were testing against NULL. This only happens when the only inet_diag modular user, DCCP, is not built into the kernel or available as a module. Also there was a problem with not dropping the mutex lock when a handler was not found, also fixed in this patch. This caused an OOPS and ss would then hang on subsequent calls, as &inet_diag_table_mutex was being left locked. Thanks to spike at ml.yaroslavl.ru for report it after trying 'ss -d' on a kernel that doesn't have DCCP available. This bug was introduced in cset d523a328fb0271e1a763e985a21f2488fd816e7e ("Fix inet_diag dead-lock regression"), after 2.6.24-rc3, so just 2.6.24 seems to be affected.

2007-12-03[INET]: Fix inet_diag dead-lock regressionHerbert Xu

2007-11-30[INET]: Fix inet_diag register vs rcv racePavel Emelyanov
The following race is possible when one cpu unregisters the handler while other one is trying to receive a message and call this one: CPU1: CPU2: inet_diag_rcv() inet_diag_unregister() mutex_lock(&inet_diag_mutex); netlink_rcv_skb(skb, &inet_diag_rcv_msg); if (inet_diag_table[nlh->nlmsg_type] == NULL) /* false handler is still registered */ ... netlink_dump_start(idiagnl, skb, nlh, inet_diag_dump, NULL); cb = kzalloc(sizeof(*cb), GFP_KERNEL); /* sleep here freeing memory * or preempt * or sleep later on nlk->cb_mutex */ spin_lock(&inet_diag_register_lock); inet_diag_table[type] = NULL; ... spin_unlock(&inet_diag_register_lock); synchronize_rcu(); /* CPU1 is sleeping - RCU quiescent * state is passed */ return; /* inet_diag_dump is finally called: */ inet_diag_dump() handler = inet_diag_table[cb->nlh->nlmsg_type]; BUG_ON(handler == NULL); /* OOPS! While we slept the unregister has set * handler to NULL :( */ Grep showed, that the register/unregister functions are called from init/fini module callbacks for tcp_/dccp_diag, so it's OK to use the inet_diag_mutex to synchronize manipulations with the inet_diag_table and the access to it. Besides, as Herbert pointed out, asynchronous dumps should hold this mutex as well, and thus, we provide the mutex as cb_mutex one.

2007-11-07[INET]: Remove per bucket rwlock in tcp/dccp ehash table.Eric Dumazet
As done two years ago on IP route cache table (commit 22c047ccbc68fa8f3fa57f0e8f906479a062c426) , we can avoid using one lock per hash bucket for the huge TCP/DCCP hash tables. On a typical x86_64 platform, this saves about 2MB or 4MB of ram, for litle performance differences. (we hit a different cache line for the rwlock, but then the bucket cache line have a better sharing factor among cpus, since we dirty it less often). For netstat or ss commands that want a full scan of hash table, we perform fewer memory accesses. Using a 'small' table of hashed rwlocks should be more than enough to provide correct SMP concurrency between different buckets, without using too much memory. Sizing of this table depends on num_possible_cpus() and various CONFIG settings. This patch provides some locking abstraction that may ease a future work using a different model for TCP/DCCP table.

2007-10-10[NET]: make netlink user -> kernel interface synchroniousDenis V. Lunev
This patch make processing netlink user -> kernel messages synchronious. This change was inspired by the talk with Alexey Kuznetsov about current netlink messages processing. He says that he was badly wrong when introduced asynchronious user -> kernel communication. The call netlink_unicast is the only path to send message to the kernel netlink socket. But, unfortunately, it is also used to send data to the user. Before this change the user message has been attached to the socket queue and sk->sk_data_ready was called. The process has been blocked until all pending messages were processed. The bad thing is that this processing may occur in the arbitrary process context. This patch changes nlk->data_ready callback to get 1 skb and force packet processing right in the netlink_unicast. Kernel -> user path in netlink_unicast remains untouched. EINTR processing for in netlink_run_queue was changed. It forces rtnl_lock drop, but the process remains in the cycle until the message will be fully processed. So, there is no need to use this kludges now. Signed-off-by: Denis V. Lunev <den@openvz.org> Acked-by: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-10[NET]: Support multiple network namespaces with netlinkEric W. Biederman
Each netlink socket will live in exactly one network namespace, this includes the controlling kernel sockets. This patch updates all of the existing netlink protocols to only support the initial network namespace. Request by clients in other namespaces will get -ECONREFUSED. As they would if the kernel did not have the support for that netlink protocol compiled in. As each netlink protocol is updated to be multiple network namespace safe it can register multiple kernel sockets to acquire a presence in the rest of the network namespaces.

2007-02-08[NET]: change layout of ehash tableEric Dumazet
ehash table layout is currently this one : First half of this table is used by sockets not in TIME_WAIT state Second half of it is used by sockets in TIME_WAIT state. This is non optimal because of for a given hash or socket, the two chain heads are located in separate cache lines. Moreover the locks of the second half are never used. If instead of this halving, we use two list heads in inet_ehash_bucket instead of only one, we probably can avoid one cache miss, and reduce ram usage, particularly if sizeof(rwlock_t) is big (various CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_LOCK_ALLOC settings). So we still halves the table but we keep together related chains to speedup lookups and socket state change. In this patch I did not try to align struct inet_ehash_bucket, but a future patch could try to make this structure have a convenient size (a power of two or a multiple of L1_CACHE_SIZE). I guess rwlock will just vanish as soon as RCU is plugged into ehash :) , so maybe we dont need to scratch our heads to align the bucket... Note : In case struct inet_ehash_bucket is not a power of two, we could probably change alloc_large_system_hash() (in case it use __get_free_pages()) to free the unused space. It currently allocates a big zone, but the last quarter of it could be freed. Again, this should be a temporary 'problem'. Patch tested on ipv4 tcp only, but should be OK for IPV6 and DCCP.
