* SCTP: Allow ADD_IP to work with AUTH for backward compatibility.Vlad Yasevich2007-11-07
| | | | | | | | | | This patch adds a tunable that will allow ADD_IP to work without AUTH for backward compatibility. The default value is off since the default value for ADD_IP is off as well. People who need to use ADD-IP with older implementations take risks of connection hijacking and should consider upgrading or turning this tunable on.

* SCTP: Update RCU handling during the ADD-IP caseVlad Yasevich2007-11-07
| | | | | | | | | | After learning more about rcu, it looks like the ADD-IP hadling doesn't need to call call_rcu_bh. All the rcu critical sections use rcu_read_lock, so using call_rcu_bh is wrong here. Now, restore the local_bh_disable() code blocks and use normal call_rcu() calls. Also restore the missing return statement. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
* SCTP: Fix difference cases of retransmit.Vlad Yasevich2007-11-07
| | | | | | | | | | | | | | | | | | | | | Commit d0ce92910bc04e107b2f3f2048f07e94f570035d broke several retransmit cases including fast retransmit. 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.

* SCTP : Fix to process bundled ASCONF chunk correctlyWei Yongjun2007-11-07
| | | | | | | | | | | | | | If ASCONF chunk is bundled with other chunks as the first chunk, when process the ASCONF parameters, full packet data will be process as the parameters of the ASCONF chunk, not only the real parameters. So if you send a ASCONF chunk bundled with other chunks, you will get an unexpect result. This problem also exists when ASCONF-ACK chunk is bundled with other chunks. This patch fix this problem.

* [NETLINK]: Fix unicast timeoutsPatrick McHardy2007-11-07
| | | | | | | | | | | | | Commit ed6dcf4a in the history.git tree broke netlink_unicast timeouts by moving the schedule_timeout() call to a new function that doesn't propagate the remaining timeout back to the caller. This means on each retry we start with the full timeout again. ipc/mqueue.c seems to actually want to wait indefinitely so this behaviour is retained.

* [INET]: Remove per bucket rwlock in tcp/dccp ehash table.Eric Dumazet2007-11-07
| | | | | | | | | | | | | | | | | | | | | | | | 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. Bogdanovski2007-11-07
| | | | | | | | | | | | | | | | | | | | | | | | 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. Bogdanovski2007-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Dave Miller noted various cases where line disciplines for things like ppp go poking around in termios themselves in ways that broke with the new termios code. Rather than have them all learning about termios internals provide proper methods for this - tty_mode_ioctl() This handles all the terminal mode handling for speed/carrier etc and none of the methods are ldisc dependant so they can be called by any user - tty_perform_flush() This extracts the flush functionality and enables pppd the ppp layer to share it cleanly. The existing n_tty_ioctl code is refactored in this patch to provide the new functions and to call them itself appropriately. This patch has no (intended) behaviour changes and simply prepares for the other fixes. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [PKT_SCHED] CLS_U32: Fix endianness problem with u32 classifier hash masks.Radu Rendec2007-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While trying to implement u32 hashes in my shaping machine I ran into a possible bug in the u32 hash/bucket computing algorithm (net/sched/cls_u32.c). The problem occurs only with hash masks that extend over the octet boundary, on little endian machines (where htonl() actually does something). Let's say that I would like to use 0x3fc0 as the hash mask. This means 8 contiguous "1" bits starting at b6. With such a mask, the expected (and logical) behavior is to hash any address in, for instance, 192.168.0.0/26 in bucket 0, then any address in 192.168.0.64/26 in bucket 1, then 192.168.0.128/26 in bucket 2 and so on. This is exactly what would happen on a big endian machine, but on little endian machines, what would actually happen with current implementation is 0x3fc0 being reversed (into 0xc03f0000) by htonl() in the userspace tool and then applied to 192.168.x.x in the u32 classifier. When shifting right by 16 bits (rank of first "1" bit in the reversed mask) and applying the divisor mask (0xff for divisor 256), what would actually remain is 0x3f applied on the "168" octet of the address. One could say is this can be easily worked around by taking endianness into account in userspace and supplying an appropriate mask (0xfc03) that would be turned into contiguous "1" bits when reversed (0x03fc0000). But the actual problem is the network address (inside the packet) not being converted to host order, but used as a host-order value when computing the bucket. Let's say the network address is written as n31 n30 ... n0, with n0 being the least significant bit. When used directly (without any conversion) on a little endian machine, it becomes n7 ... n0 n8 ..n15 etc in the machine's registers. Thus bits n7 and n8 would no longer be adjacent and 192.168.64.0/26 and 192.168.128.0/26 would no longer be consecutive. The fix is to apply ntohl() on the hmask before computing fshift, and in u32_hash_fold() convert the packet data to host order before shifting down by fshift.

* [NET]: Define infrastructure to keep 'inuse' changes in an efficent SMP/NUMA ↵Eric Dumazet2007-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Users are only running into this now because distros are now using 2.6.23 and I must have messed up when I tested the change. For receive, we now do our own calculation of how much to pull from the skb (variable length L2TP header) rather than using skb_transport_offset(). Also, if the skb isn't a data packet, it must be passed back to UDP with skb->data pointing to the UDP header. For transmit, make sure skb->sk is set up because ip_queue_xmit() needs it.
