* [SCTP]: Fix the bind_addr info during migration.Vlad Yasevich2007-12-07
| | | | | | | | | | During accept/migrate the code attempts to copy the addresses from the parent endpoint to the new endpoint. However, if the parent was bound to a wildcard address, then we end up pointlessly copying all of the current addresses on the system.

* [SCTP]: Add bind hash locking to the migrate codeVlad Yasevich2007-12-07
| | | | | | | | | | SCTP accept code tries to add a newliy created socket to a bind bucket without holding a lock. On a really busy system, that can causes slab corruptions. Add a lock around this code. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* SCTP: Fix build issues with SCTP AUTH.Vlad Yasevich2007-11-29
| | | | | | | | SCTP-AUTH requires selection of CRYPTO, HMAC and SHA1 since SHA1 is a MUST requirement for AUTH. We also support SHA256, but that's optional, so fix the code to treat it as such. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
* SCTP: Fix chunk acceptance when no authenticated chunks were listed.Vlad Yasevich2007-11-29
| | | | | | | | | In the case where no autheticated chunks were specified, we were still trying to verify that a given chunk needs authentication and doing so incorrectly. Add a check for parameter length to make sure we don't try to use an empty auth_chunks parameter to verify against. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
* SCTP: Fix the supported extensions paramterVlad Yasevich2007-11-29
| | | | | | | | | Supported extensions parameter was not coded right and ended up over-writing memory or causing skb overflows. First, remove the FWD_TSN support from as it shouldn't be there and also fix the paramter encoding. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
* SCTP: Fix SCTP-AUTH to correctly add HMACS paramter.Vlad Yasevich2007-11-29

* SCTP: Fix the number of HB transmissions.Vlad Yasevich2007-11-29
| | | | | | | | | | Our treatment of Heartbeats is special in that the inital HB chunk counts against the error count for the association, where as for other chunks, only retransmissions or timeouts count against us. As a result, we had an off-by-1 situation with a number of Heartbeats we could send. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

* Fix memory leak in discard case of sctp_sf_abort_violation()Jesper Juhl2007-11-12
| | | | | | | | | | | | | | | | In net/sctp/sm_statefuns.c::sctp_sf_abort_violation() we may leak the storage allocated for 'abort' by returning from the function without using or freeing it. This happens in case "sctp_auth_recv_cid(SCTP_CID_ABORT, asoc)" is true and we jump to the 'discard' label. Spotted by the Coverity checker. The simple fix is to simply move the creation of the "abort chunk" to after the possible jump to the 'discard' label. This way we don't even have to allocate the memory at all in the problem case.

* SCTP: Always flush the queue when uncorcking.Vlad Yasevich2007-11-09
| | | | | | | | | | | | | | | When the code calls uncork, trigger a queue flush, even if the queue was not corked. Most callers that explicitely cork the queue will have additinal checks to see if they corked it. Callers who do not cork the queue expect packets to flow when they call uncork. The scneario that showcased this bug happend when we were not able to bundle DATA with outgoing COOKIE-ECHO. As a result the data just sat in the outqueue and did not get transmitted. The application expected a response, but nothing happened. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
* SCTP: Fix PR-SCTP to deliver all the accumulated ordered chunksVlad Yasevich2007-11-09
| | | | | | | | | | There is a small bug when we process a FWD-TSN. We'll deliver anything upto the current next expected SSN. However, if the next expected is already in the queue, it will take another chunk to trigger its delivery. The fix is to simply check the current queued SSN is the next expected one.

* SCTP: Make sctp_verify_param return multiple indications.Vlad Yasevich2007-11-09
| | | | | | | | | | SCTP-AUTH and future ADD-IP updates have a requirement to do additional verification of parameters and an ability to ABORT the association if verification fails.

* SCTP: Use hashed lookup when looking for an association.Vlad Yasevich2007-11-09
| | | | | | | | A SCTP endpoint may have a lot of associations on them and walking the list is fairly inefficient. Instead, use a hashed lookup, and filter out the hash list based on the endopoing we already have. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
* SCTP: Fix a potential race between timers and receive path.Vlad Yasevich2007-11-07
| | | | | | | | | | | | | | There is a possible race condition where the timer code will free the association and the next packet in the queue will also attempt to free the same association. The example is, when we receive an ABORT at about the same time as the retransmission timer fires. If the timer wins the race, it will free the association. Once it releases the lock, the queue processing will recieve the ABORT and will try to free the association again. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
* 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.

| | | | | | | | | | 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.

* 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.

* [NET]: Make the device list and device lookups per namespace.Eric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

* [NET]: Make socket creation namespace safe.Eric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | This patch passes in the namespace a new socket should be created in and has the socket code do the appropriate reference counting. By virtue of this all socket create methods are touched. In addition the socket create methods are modified so that they will fail if you attempt to create a socket in a non-default network namespace. Failing if we attempt to create a socket outside of the default network namespace ensures that as we incrementally make the network stack network namespace aware we will not export functionality that someone has not audited and made certain is network namespace safe. Allowing us to partially enable network namespaces before all of the exotic protocols are supported. Any protocol layers I have missed will fail to compile because I now pass an extra parameter into the socket creation code.
