* [NET]: Fix heavy stack usage in seq_file output routines.Pavel Emelyanov2008-04-24
| | | | | | | | | Plan C: we can follow the Al Viro's proposal about %n like in this patch. The same applies to udp, fib (the /proc/net/route file), rt_cache and sctp debug. This is minus ~150-200 bytes for each. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* SCTP: Initialize partial_bytes_acked to 0, when all of the data is acked.Gui Jianfeng2008-04-17
| | | | | | | | | | | | | According to RFC4960 7.2.2, When all of the data transmitted by the sender has been acknowledged by the recerver, partial_bytes_acked is initialized to 0. This patch conforms to rfc requirement. Without this fix, cwnd might be error incremented.

| * [SCTP]: IPv4 vs IPv6 addresses mess in sctp_inet[6]addr_event.Pavel Emelyanov2008-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All IP addresses that are present in a system are duplicated on struct sctp_sockaddr_entry. They are linked in the global list called sctp_local_addr_list. And this struct unions IPv4 and IPv6 addresses. So, there can be rare case, when a sockaddr_in.sin_addr coincides with the corresponding part of the sockaddr_in6 and the notifier for IPv4 will carry away an IPv6 entry. The fix is to check the family before comparing the addresses. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.

| * [SCTP]: Fix protocol violation when receiving an error lenght INIT-ACKGui Jianfeng2008-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When receiving an error length INIT-ACK during COOKIE-WAIT, a 0-vtag ABORT will be responsed. This action violates the protocol apparently. This patch achieves the following things. 1 If the INIT-ACK contains all the fixed parameters, use init-tag recorded from INIT-ACK as vtag. 2 If the INIT-ACK doesn't contain all the fixed parameters, just reflect its vtag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC 4890 has the following text: The HMAC algorithm based on SHA-1 MUST be supported and included in the HMAC-ALGO parameter. As a result, we need to check in sctp_verify_param() that HMAC_SHA1 is present in the list. If not, we should probably treat this as a protocol violation. It should also be a protocol violation if the HMAC parameter is empty.

| * [SCTP]: Fix a race between module load and protosw accessVlad Yasevich2008-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race is SCTP between the loading of the module and the access by the socket layer to the protocol functions. In particular, a list of addresss that SCTP maintains is not initialized prior to the registration with the protosw. Thus it is possible for a user application to gain access to SCTP functions before everything has been initialized. The problem shows up as odd crashes during connection initializtion when we try to access the SCTP address list. The solution is to refactor how we do registration and initialize the lists prior to registering with the protosw. Care must be taken since the address list initialization depends on some other pieces of SCTP initialization. Also the clean-up in case of failure now also needs to be refactored.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an address family is not listed in "Supported Address Types" parameter(INIT Chunk), but the packet is sent by that family, this address family should be considered as supported by peer. Otherwise, an error condition will occur. For instance, if kernel receives an IPV6 SCTP INIT chunk with "Support Address Types" parameter which indicates just supporting IPV4 Address family. Kernel will reply an IPV6 SCTP INIT ACK packet, but the source ipv6 address in ipv6 header will be vacant. This is not correct. refer to RFC4460 as following: IMPLEMENTATION NOTE: If an SCTP endpoint lists in the 'Supported Address Types' parameter either IPv4 or IPv6, but uses the other family for sending the packet containing the INIT chunk, or if it also lists addresses of the other family in the INIT chunk, then the address family that is not listed in the 'Supported Address Types' parameter SHOULD also be considered as supported by the receiver of the INIT chunk. The receiver of the INIT chunk SHOULD NOT respond with any kind of error indication. Here is a fix to comply to RFC.
