This updates xt_recent to support the IPv6 address family. The new /proc/net/xt_recent directory must be used for this. The old proc interface can also be configured out. Signed-off-by:

Like with other modules (such as ipt_state), ipt_recent.h is changed to forward definitions to (IOW include) xt_recent.h, and xt_recent.c is changed to use the new constant names. Signed-off-by:

idev has been stored on seq->private. NULL has been stored for global statistics. The situation is changed with net namespace. We need to store pointer to struct net and the only place is seq->private. So, we'll have for /proc/net/dev_snmp6/* and for /proc/net/snmp6 pointers of two different types stored in the same field. This effectively requires to separate seq_ops of these files. Signed-off-by:

It all started from me noticing that this urgent check in tcp_clean_rtx_queue is unnecessarily inside the loop. Then I took a longer look to it and found out that the users of urg_mode can trivially do without, well almost, there was one gotcha. Bonus: those funny people who use urg with >= 2^31 write_seq - snd_una could now rejoice too (that's the only purpose for the between being there, otherwise a simple compare would have done the thing). Not that I assume that the rest of the tcp code happily lives with such mind-boggling numbers :-). Alas, it turned out to be impossible to set wmem to such numbers anyway, yes I really tried a big sendfile after setting some wmem but nothing happened :-). ...Tcp_wmem is int and so is sk_sndbuf... So I hacked a bit variable to long and found out that it seems to work... :-) Signed-off-by:

Add some packet-split receive hooks. For one this allows to do NUMA node affine page allocs. Later on these hooks will be extended to do emergency reserve allocations for fragments. Signed-off-by:

qdisc->requeue was planned to universally replace all requeuing code, but at the top level we never requeue more than one skb, so qdisc-> gso_skb is enough for this. qdisc->requeue would be used on the lower levels only for one level deep requeuing (like in sch_hfsc) after finishing all the changes.

This protocol provides some connection handling and negotiated congestion control. Nokia cellular modems use it for bulk transfers. It provides packet boundaries (hence SOCK_SEQPACKET). Congestion control is per packet rather per byte, so we do not re-use the generic socket memory accounting. Signed-off-by:

RFC3873 defined SCTP_MIB_OUTOFBLUES: sctpOutOfBlues OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of out of the blue packets received by the host. An out of the blue packet is an SCTP packet correctly formed, including the proper checksum, but for which the receiver was unable to identify an appropriate association." REFERENCE "Section 8.4 in RFC2960 deals with the Out-Of-The-Blue (OOTB) packet definition and procedures." But OOTB packet INIT, INIT-ACK and SHUTDOWN-ACK(COOKIE-WAIT or COOKIE-ECHOED state) are not counted by SCTP_MIB_OUTOFBLUES. Case 1(INIT): Endpoint A Endpoint B (CLOSED) (CLOSED) INIT ----------> <---------- ABORT Case 2(INIT-ACK): Endpoint A Endpoint B (CLOSED) (CLOSED) INIT-ACK ----------> <---------- ABORT Case 3(SHUTDOWN-ACK): Endpoint A Endpoint B (CLOSED) (CLOSED) <---------- INIT SHUTDOWN-ACK ----------> <---------- SHUTDOWN-COMPLETE Case 4(SHUTDOWN-ACK): Endpoint A Endpoint B (CLOSED) (COOKIE-ECHOED) SHUTDOWN-ACK ----------> <---------- SHUTDOWN-COMPLETE This patch fixed the problem.

RFC 4960: Section 9.2 The sender of the SHUTDOWN MAY also start an overall guard timer 'T5-shutdown-guard' to bound the overall time for the shutdown sequence. At the expiration of this timer, the sender SHOULD abort the association by sending an ABORT chunk. If the 'T5-shutdown- guard' timer is used, it SHOULD be set to the recommended value of 5 times 'RTO.Max'. The timer 'T5-shutdown-guard' is used to counter the overall time for shutdown sequence, and it's start by the sender of the SHUTDOWN. So timer 'T5-shutdown-guard' should be start when we send the first SHUTDOWN chunk and enter the SHUTDOWN-SENT state, not start when we receipt of the SHUTDOWN primitive and enter SHUTDOWN-PENDING state. If 'T5-shutdown-guard' timer is start at SHUTDOWN-PENDING state, the association may be ABORT while data is still transmitting. Signed-off-by:

sctp_is_any() function that is used to check for wildcard addresses only looks at the address itself to determine the address family. This function is used in the API to check the address passed in from the user. If the user simply zerroes out the sockaddr_storage and pass that in, we'll end up failing. So, let's try harder to determine the address family by also checking the socket if it's possible. Signed-off-by: -
