* [DCCP]: Convert Reset code into socket error numberGerrit Renker2007-10-242-9/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for converting the 11 currently defined Reset codes into system error numbers, which are stored in sk_err for further interpretation. This makes the externally visible API behaviour similar to TCP, since a client connecting to a non-existing port will experience ECONNREFUSED. * Code 0, Unspecified, is interpreted as non-error (0); * Code 1, Closed (normal termination), also maps into 0; * Code 2, Aborted, maps into "Connection reset by peer" (ECONNRESET); * Code 3, No Connection and Code 7, Connection Refused, map into "Connection refused" (ECONNREFUSED); * Code 4, Packet Error, maps into "No message of desired type" (ENOMSG); * Code 5, Option Error, maps into "Illegal byte sequence" (EILSEQ); * Code 6, Mandatory Error, maps into "Operation not supported on transport endpoint" (EOPNOTSUPP); * Code 8, Bad Service Code, maps into "Invalid request code" (EBADRQC); * Code 9, Too Busy, maps into "Too many users" (EUSERS); * Code 10, Bad Init Cookie, maps into "Invalid request descriptor" (EBADR); * Code 11, Aggression Penalty, maps into "Quota exceeded" (EDQUOT) which makes sense in terms of using more than the `fair share' of bandwidth.

* [DCCP]: One more exemption from full sequence number checksGerrit Renker2007-10-241-1/+1
| | | | | | | | | | | | | | | | | | | | This fixes the following problem: client connects to peer which has no DCCP enabled or loaded; ICMP error messages ("Protocol Unavailable") can be seen on the wire, but the application hangs. Reason: ICMP packets don't get through to dccp_v4_err. When reporting errors, a sequence number check is made for the DCCP packet that had caused an ICMP error to arrive. Such checks can not be made if the socket is in state LISTEN, RESPOND (which in the implementation is the same as LISTEN), or REQUEST, since update_gsr() has not been called in these states, hence the sequence window is 0..0. This patch fixes the problem by adding the REQUEST state as another exemption to the window check. The error reporting now works as expected on connecting.

* [DCCP]: Retrieve packet sequence number for error reportingGerrit Renker2007-10-243-10/+8
| | | | | | | | | | | | | | This fixes a problem when analysing erroneous packets in dccp_v{4,6}_err: * dccp_hdr_seq currently takes an skb * however, the transport headers in the skb are shifted, due to the preceding IPv4/v6 header. Fixed for v4 and v6 by changing dccp_hdr_seq to take a struct dccp_hdr as argument. Verified that the correct sequence number is now reported in the error handler.

* [IPV4]: Explicitly call fib_get_table() in fib_frontend.cPavel Emelyanov2007-10-231-5/+7
| | | | | | | | | | | In case the "multiple tables" config option is y, the ip_fib_local_table is not a variable, but a macro, that calls fib_get_table(RT_TABLE_LOCAL). Some code uses this "variable" *3* times in one place, thus implicitly making 3 calls. Fix it. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Polling currently calls the irq handler, which loops through all the boards, calling the work function for all polling boards with work. irq handling loops through all the boards, finding the specific board that applies to us, and calling the work just for that one board.
