* inet: toss struct net initialization aroundPavel Emelyanov2008-07-151-1/+2
| | | | | | | | | | | | | Some places, that deal with ICMP statistics already have where to get a struct net from, but use it directly, without declaring a separate variable on the stack. Since I will need this net soon, I declare a struct net on the stack and use it in the existing places in a separate patch not to spoil the future ones.

* dccp ccid-3: Length of loss intervalsGerrit Renker2008-07-131-5/+5
| | | | | | | | | | | | | | | | This corrects an error in the computation of the open loss interval I_0: * the interval length is (highest_seqno - start_seqno) + 1 * and not (highest_seqno - start_seqno). This condition was not fully clear in RFC 3448, but reflects the current revision state of rfc3448bis and is also consistent with RFC 4340, 6.1.1. Further changes: ---------------- * variable renamed due to line length constraints; * explicit typecast to `s64' to avoid implicit signed/unsigned casting.

* dccp ccid-3: Fix a loss detection bugGerrit Renker2008-07-133-33/+27
| | | | | | | | | | | | | | | | | | | | | | | This fixes a bug in the logic of the TFRC loss detection: * new_loss_indicated() should not be called while a loss is pending; * but the code allows this; * thus, for two subsequent gaps in the sequence space, when loss_count has not yet reached NDUPACK=3, the loss_count is falsely reduced to 1. To avoid further and similar problems, all loss handling and loss detection is now done inside tfrc_rx_hist_handle_loss(), using an appropriate routine to track new losses. Further changes: ---------------- * added a reminder that no RX history operations should be performed when rx_handle_loss() has identified a (new) loss, since the function takes care of packet reordering during loss detection; * made tfrc_rx_hist_loss_pending() bool (thanks to an earlier suggestion by Arnaldo); * removed unused functions.

* dccp: Upgrade NDP count from 3 to 6 bytesGerrit Renker2008-07-134-13/+15
| | | | | | | | RFC 4340, 7.7 specifies up to 6 bytes for the NDP Count option, whereas the code is currently limited to up to 3 bytes. This seems to be a relict of an earlier draft version and is brought up to date by the patch. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
* dccp ccid-3: Fix error in loss detectionGerrit Renker2008-07-132-45/+43
| | | | | | | | | | | | | | | | | The TFRC loss detection code used the wrong loss condition (RFC 4340, 7.7.1): * the difference between sequence numbers s1 and s2 instead of * the number of packets missing between s1 and s2 (one less than the distance). Since this condition appears in many places of the code, it has been put into a separate function, dccp_loss_free(). Further changes: ---------------- * tidied up incorrect typing (it was using `int' for u64/s64 types); * optimised conditional statements for common case of non-reordered packets; * rewrote comments/documentation to match the changes.

* dccp ccid-3: X truncated due to type conversionGerrit Renker2008-06-111-8/+6
| | | | | | | | | | | | This fixes a bug in computing the inter-packet-interval t_ipi = s/X: scaled_div32(a, b) uses u32 for b, but in "scaled_div32(s, X)" the type of the sending rate `X' is u64. Since X is scaled by 2^6, this truncates rates greater than 2^26 Bps (~537 Mbps). Using full 64-bit division now. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
* dccp ccid-3: TFRC reverse-lookup Bug-FixGerrit Renker2008-06-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | This fixes a bug in the reverse lookup of p: given a value f(p), instead of p, the function returned the smallest tabulated value f(p). The smallest tabulated value of 10^6 * f(p) = sqrt(2*p/3) + 12 * sqrt(3*p/8) * (32 * p^3 + p) for p=0.0001 is 8172. Since this value is scaled by 10^6, the outcome of this bug is that a loss of 8172/10^6 = 0.8172% was reported whenever the input was below the table resolution of 0.01%. This means that the value was over 80 times too high, resulting in large spikes of the initial loss interval, thus unnecessarily reducing the throughput. Also corrected the printk format (%u for u32). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
* dccp ccid-2: Bug-Fix - Ack Vectors need to be ignored on request socketsGerrit Renker2008-06-111-1/+3
| | | | | | | | | | | | | | | | | | | | | This fixes an oversight from an earlier patch, ensuring that Ack Vectors are not processed on request sockets. The issue is that Ack Vectors must not be parsed on request sockets, since the Ack Vector feature depends on the selection of the (TX) CCID. During the initial handshake the CCIDs are undefined, and so RFC 4340, 10.3 applies: "Using CCID-specific options and feature options during a negotiation for the corresponding CCID feature is NOT RECOMMENDED [...]" And it is not even possible: when the server receives the Request from the client, the CCID and Ack vector features are undefined; when the Ack finalising the 3-way hanshake arrives, the request socket has not been cloned yet into a full socket. (This order is necessary, since otherwise the newly created socket would have to be destroyed whenever an option error occurred - a malicious hacker could simply send garbage options and exploit this.)

* dccp ccid-3: Bug-Fix - Zero RTT is possibleGerrit Renker2008-06-111-2/+8
| | | | | | | | | | | | | | | | | | | | | In commit $(825de27d9e40b3117b29a79d412b7a4b78c5d815) (from 27th May, commit message `dccp ccid-3: Fix "t_ipi explosion" bug'), the CCID-3 window counter computation was fixed to cope with RTTs < 4 microseconds. Such RTTs can be found e.g. when running CCID-3 over loopback. The fix removed a check against RTT < 4, but introduced a divide-by-zero bug. All steady-state RTTs in DCCP are filtered using dccp_sample_rtt(), which ensures non-zero samples. However, a zero RTT is possible on initialisation, when there is no RTT sample from the Request/Response exchange. The fix is to use the fallback-RTT from RFC 4340, 3.4. This is also better than just fixing update_win_count() since it allows other parts of the code to always assume that the RTT is non-zero during the time that the CCID is used.

* dccp ccid-3: Fix "t_ipi explosion" bugGerrit Renker2008-05-271-9/+4
| | | | | | | | | | | | | | | | | | | | | | The identification of this bug is thanks to Cheng Wei and Tomasz Grobelny. To avoid divide-by-zero, the implementation previously ignored RTTs smaller than 4 microseconds when performing integer division RTT/4. When the RTT reached a value less than 4 microseconds (as observed on loopback), this prevented the Window Counter CCVal value from advancing. As a result, the receiver stopped sending feedback. This in turn caused non-ending expiries of the nofeedback timer at the sender, so that the sending rate was progressively reduced until reaching the minimum of one packet per 64 seconds. The patch fixes this bug by handling integer division more intelligently. Due to consistent use of dccp_sample_rtt(), divide-by-zero-RTT is avoided.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_queue_xmit() and the other IP output functions expect to get a skb with clear or properly initialized skb->cb. Unlike TCP and UDP, the dccp_skb_cb doesn't contain a struct inet_skb_parm at the beginning, so the DCCP-specific data is interpreted by the IP output functions. This can cause false negatives for the conditional POST_ROUTING hook invocation, making the packet bypass the hook. Add a inet_skb_parm/inet6_skb_parm union to the beginning of dccp_skb_cb to avoid clashes. Also add a BUILD_BUG_ON to make sure it fits in the cb.

* | [SOCK]: Add udp_hash member to struct proto.Pavel Emelyanov2008-03-232-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inspired by the commit ab1e0a13 ([SOCK] proto: Add hashinfo member to struct proto) from Arnaldo, I made similar thing for UDP/-Lite IPv4 and -v6 protocols. The result is not that exciting, but it removes some levels of indirection in udpxxx_get_port and saves some space in code and text. The first step is to union existing hashinfo and new udp_hash on the struct proto and give a name to this union, since future initialization of tcpxxx_prot, dccp_vx_protinfo and udpxxx_protinfo will cause gcc warning about inability to initialize anonymous member this way.
