* [IPV4]: Fix memory leak in inet_hashtables.h when NUMA is onPavel Emelyanov2007-11-261-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The inet_ehash_locks_alloc() looks like this: #ifdef CONFIG_NUMA if (size > PAGE_SIZE) x = vmalloc(...); else #endif x = kmalloc(...); Unlike it, the inet_ehash_locks_alloc() looks like this: #ifdef CONFIG_NUMA if (size > PAGE_SIZE) vfree(x); else #else kfree(x); #endif The error is obvious - if the NUMA is on and the size is less than the PAGE_SIZE we leak the pointer (kfree is inside the #else branch). Compiler doesn't warn us because after the kfree(x) there's a "x = NULL" assignment, so here's another (minor?) bug: we don't set x to NULL under certain circumstances. Boring explanation, I know...

* | [TCP]: Fix TCP header misalignmentHerbert Xu2007-11-181-0/+3
|/ | | | | | | | | | | | | | | | | | | | | Indeed my previous change to alloc_pskb has made it possible for the TCP header to be misaligned iff the MTU is not a multiple of 4 (and less than a page). So I suspect the optimised IPsec MTU calculation is giving you just such an MTU :) This patch fixes it by changing alloc_pskb to make sure that the size is at least 32-bit aligned. This does not cause the problem fixed by the previous patch because max_header is always 32-bit aligned which means that in the SG/NOTSO case this will be a no-op. I thought about putting this in the callers but all the current callers are from TCP. If and when we get a non-TCP caller we can always create a TCP wrapper for this function and move the alignment over there.

* [INET]: Fix potential kfree on vmalloc-ed area of request_sock_queuePavel Emelyanov2007-11-151-17/+1
| | | | | | | | | | | | | | | | | | | | | | | | The request_sock_queue's listen_opt is either vmalloc-ed or kmalloc-ed depending on the number of table entries. Thus it is expected to be handled properly on free, which is done in the reqsk_queue_destroy(). However the error path in inet_csk_listen_start() calls the lite version of reqsk_queue_destroy, called __reqsk_queue_destroy, which calls the kfree unconditionally. Fix this and move the __reqsk_queue_destroy into a .c file as it looks too big to be inline. As David also noticed, this is an error recovery path only, so no locking is required and the lopt is known to be not NULL. reqsk_queue_yank_listen_sk is also now only used in net/core/request_sock.c so we should move it there too.

* [TCP]: Fix size calculation in sk_stream_alloc_pskbHerbert Xu2007-11-141-4/+6
| | | | | | | | | | | | | | | | | | | | | | We round up the header size in sk_stream_alloc_pskb so that TSO packets get zero tail room. Unfortunately this rounding up is not coordinated with the select_size() function used by TCP to calculate the second parameter of sk_stream_alloc_pskb. As a result, we may allocate more than a page of data in the non-TSO case when exactly one page is desired. In fact, rounding up the head room is detrimental in the non-TSO case because it makes memory that would otherwise be available to the payload head room. TSO doesn't need this either, all it wants is the guarantee that there is no tail room. So this patch fixes this by adjusting the skb_reserve call so that exactly the requested amount (which all callers have calculated in a precise way) is made available as tail room.

The reason is that we should only delay by rto while doing retranmists as a result of a timeout. Retransmit as a result of path mtu discover, fast retransmit, or other evernts that should trigger immidiate retransmissions got broken. Also, since rto is doubled prior to marking of packets elegable for retransmission, we never marked correct chunks anyway. The fix is provide a reason for a given retransmission so that we can mark chunks appropriately and to save the old rto value to do comparisons against. All regressions tests passed with this code.

* [INET]: Remove per bucket rwlock in tcp/dccp ehash table.Eric Dumazet2007-11-071-6/+65
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* [IPVS]: Synchronize closing of ConnectionsRumen G. Bogdanovski2007-11-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | This patch makes the master daemon to sync the connection when it is about to close. This makes the connections on the backup to close or timeout according their state. Before the sync was performed only if the connection is in ESTABLISHED state which always made the connections to timeout in the hard coded 3 minutes. However the Andy Gospodarek's patch ([IPVS]: use proper timeout instead of fixed value) effectively did nothing more than increasing this to 15 minutes (Established state timeout). So this patch makes use of proper timeout since it syncs the connections on status changes to FIN_WAIT (2min timeout) and CLOSE (10sec timeout). However if the backup misses CLOSE hopefully it did not miss FIN_WAIT. Otherwise we will just have to wait for the ESTABLISHED state timeout. As it is without this patch. This way the number of the hanging connections on the backup is kept to minimum. And very few of them will be left to timeout with a long timeout. This is important if we want to make use of the fix for the real server overcommit on master/backup fail-over. Signed-off-by: Rumen G.

* [IPVS]: Bind connections on stanby if the destination existsRumen G. Bogdanovski2007-11-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the problem with node overload on director fail-over. Given the scenario: 2 nodes each accepting 3 connections at a time and 2 directors, director failover occurs when the nodes are fully loaded (6 connections to the cluster) in this case the new director will assign another 6 connections to the cluster, If the same real servers exist there. The problem turned to be in not binding the inherited connections to the real servers (destinations) on the backup director. Therefore: "ipvsadm -l" reports 0 connections: root@test2:~# ipvsadm -l IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP test2.local:5999 wlc -> node473.local:5999 Route 1000 0 0 -> node484.local:5999 Route 1000 0 0 while "ipvs -lnc" is right root@test2:~# ipvsadm -lnc IPVS connection entries pro expire state source virtual destination TCP 14:56 ESTABLISHED 192.168.0.10:39164 192.168.0.222:5999 192.168.0.51:5999 TCP 14:59 ESTABLISHED 192.168.0.10:39165 192.168.0.222:5999 192.168.0.52:5999 So the patch I am sending fixes the problem by binding the received connections to the appropriate service on the backup director, if it exists, else the connection will be handled the old way. So if the master and the backup directors are synchronized in terms of real services there will be no problem with server over-committing since new connections will not be created on the nonexistent real services on the backup. However if the service is created later on the backup, the binding will be performed when the next connection update is received. With this patch the inherited connections will show as inactive on the backup: root@test2:~# ipvsadm -l IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP test2.local:5999 wlc -> node473.local:5999 Route 1000 0 1 -> node484.local:5999 Route 1000 0 1 rumen@test2:~$ cat /proc/net/ip_vs IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP C0A800DE:176F wlc -> C0A80033:176F Route 1000 0 1 -> C0A80032:176F Route 1000 0 1 Regards, Rumen Bogdanovski Acked-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Rumen G.

* [NET]: Define infrastructure to keep 'inuse' changes in an efficent SMP/NUMA ā†µEric Dumazet2007-11-071-6/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | way. "struct proto" currently uses an array stats[NR_CPUS] to track change on 'inuse' sockets per protocol. If NR_CPUS is big, this means we use a big memory area for this. Moreover, all this memory area is located on a single node on NUMA machines, increasing memory pressure on the boot node. In this patch, I tried to : - Keep a fast !CONFIG_SMP implementation - Keep a fast CONFIG_SMP implementation for often used protocols (tcp,udp,raw,...) - Introduce a NUMA efficient implementation Some helper macros are defined in include/net/sock.h These macros take into account CONFIG_SMP If a "struct proto" is declared without using DEFINE_PROTO_INUSE / REF_PROTO_INUSE macros, it will automatically use a default implementation, using a dynamically allocated percpu zone. This default implementation will be NUMA efficient, but might use 32/64 bytes per possible cpu because of current alloc_percpu() implementation. However it still should be better than previous implementation based on stats[NR_CPUS] field. When a "struct proto" is changed to use the new macros, we use a single static "int" percpu variable, lowering the memory and cpu costs, still preserving NUMA efficiency.

| | | | | | | | | Reworked skb_clone looks uglier with the single ifdef CONFIG_NET_CLS_ACT This patch introduces skb_act_clone which will replace skb_clone in tc actions Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S. Miller <davem@davemloft.net>
* [UDP]: Make use of inet_iif() when doing socket lookups.Vlad Yasevich2007-10-252-6/+7
| | | | | | | | | | | | | | UDP currently uses skb->dev->ifindex which may provide the wrong information when the socket bound to a specific interface. This patch makes inet_iif() accessible to UDP and makes UDP use it. The scenario we are trying to fix is when a client is running on the same system and the server and both client and server bind to a non-loopback device.

* [NET]: Don't declare extern variables in net/core/sysctl_net_core.cPavel Emelyanov2007-10-231-0/+2
| | | | | | | | | | | Some are already declared in include/linux/netdevice.h, while some others (xfrm ones) need to be declared. The driver/net/rrunner.c just uses same extern as well, so cleanup it also. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [TCP]: Remove unneeded implicit type cast when calling tcp_minshall_update()Chuck Lever2007-10-231-1/+1
| | | | | | | | | | | The tcp_minshall_update() function is called in exactly one place, and is passed an unsigned integer for the mss_len argument. Make the sign of the argument match the sign of the passed variable in order to eliminate an unneeded implicit type cast and a mixed sign comparison in tcp_minshall_update().

* [Bluetooth] Add support for handling simple eSCO linksMarcel Holtmann2007-10-221-0/+1
| | | | | | | | | | With the Bluetooth 1.2 specification the Extended SCO feature for better audio connections was introduced. So far the Bluetooth core wasn't able to handle any eSCO connections correctly. This patch adds simple eSCO support while keeping backward compatibility with older devices.

* [Bluetooth] Retrieve L2CAP features mask on connection setupMarcel Holtmann2007-10-221-2/+12
| | | | | | | | | | The Bluetooth 1.2 specification introduced a specific features mask value to interoperate with newer versions of the specification. So far this piece of information was never needed, but future extensions will rely on it. This patch adds a generic way to retrieve this information only once per connection setup.
