* net: increase the size of priv_flags and add IFF_OVS_DATAPATHSimon Horman2010-08-232-1/+3
| | | | | | | | | | | | | | | | | IFF_OVS_DATAPATH is a place-holder for the Open vSwitch datapath which I am preparing to submit for merging. As all 16 bits of priv_flags are already assigned flags, also increase the size of priv_flags to 32 bits. Unfortunately, by my calculations this increases the size of struct net_device by 4 bytes on 32bit architectures and 8 bytes on 64 bit architectures. I couldn't see an obvious way to avoid that.

* ethtool: allow non-netadmin to query settingsstephen hemminger2010-08-231-0/+1
| | | | | | | | | | | | | | | The SNMP daemon uses ethtool to determine the speed of network interfaces. This fails on Debian (and probably elsewhere) because for security SNMP daemon runs as non-root user (snmp). Note: A similar patch was rejected previously because of a concern about the possibility that on some hardware querying the ethtool settings requires access to the PHY and could slow the machine down. But the security risk of requiring SNMP daemon (and related services) to run as root far out weighs the risk of denial-of-service.

* dccp ccid-2: Replace broken RTT estimator with better algorithmGerrit Renker2010-08-232-81/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current CCID-2 RTT estimator code is in parts broken and lags behind the suggestions in RFC2988 of using scaled variants for SRTT/RTTVAR. That code is replaced by the present patch, which reuses the Linux TCP RTT estimator code. Further details: ---------------- 1. The minimum RTO of previously one second has been replaced with TCP's, since RFC4341, sec. 5 says that the minimum of 1 sec. (suggested in RFC2988, 2.4) is not necessary. Instead, the TCP_RTO_MIN is used, which agrees with DCCP's concept of a default RTT (RFC 4340, 3.4). 2. The maximum RTO has been set to DCCP_RTO_MAX (64 sec), which agrees with RFC2988, (2.5). 3. De-inlined the function ccid2_new_ack(). 4. Added a FIXME: the RTT is sampled several times per Ack Vector, which will give the wrong estimate. It should be replaced with one sample per Ack. However, at the moment this can not be resolved easily, since - it depends on TX history code (which also needs some work), - the cleanest solution is not to use the `sent' time at all (saves 4 bytes per entry) and use DCCP timestamps / elapsed time to estimated the RTT, which however is non-trivial to get right (but needs to be done). Reasons for reusing the Linux TCP estimator algorithm: ------------------------------------------------------ Some time was spent to find a better alternative, using basic RFC2988 as a first step. Further analysis and experimentation showed that the Linux TCP RTO estimator is superior to a basic RFC2988 implementation. A summary is on http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/ccid2/rto_estimator/ In addition, this estimator fared well in a recent empirical evaluation: Rewaskar, Sushant, Jasleen Kaur and F. Donelson Smith. A Performance Study of Loss Detection/Recovery in Real-world TCP Implementations. Proceedings of 15th IEEE International Conference on Network Protocols (ICNP-07), 2007. Thus there is significant benefit in reusing the existing TCP code. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
* dccp ccid-2: Simplify dec_pipe and rearming of RTO timerGerrit Renker2010-08-231-19/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the dec_pipe function and improves the way the RTO timer is rearmed when a new acknowledgment comes in. Details and justification for removal: -------------------------------------- 1) The BUG_ON in dec_pipe is never triggered: pipe is only decremented for TX history entries between tail and head, for which it had previously been incremented in tx_packet_sent; and it is not decremented twice for the same entry, since it is - either decremented when a corresponding Ack Vector cell in state 0 or 1 was received (and then ccid2s_acked==1), - or it is decremented when ccid2s_acked==0, as part of the loss detection in tx_packet_recv (and hence it can not have been decremented earlier). 2) Restarting the RTO timer happens for every single entry in each Ack Vector parsed by tx_packet_recv (according to RFC 4340, 11.4 this can happen up to 16192 times per Ack Vector). 3) The RTO timer should not be restarted when all outstanding data has been acknowledged. This is currently done similar to (2), in dec_pipe, when pipe has reached 0. The patch onsolidates the code which rearms the RTO timer, combining the segments from new_ack and dec_pipe. As a result, the code becomes clearer (compare with tcp_rearm_rto()). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
* dccp ccid-2: Remove redundant sanity testsGerrit Renker2010-08-231-52/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the ccid2_hc_tx_check_sanity function: it is redundant. Details: The tx_check_sanity function performs three tests: 1) it checks that the circular TX list is sorted - in ascending order of sequence number (ccid2s_seq) - and time (ccid2s_sent), - in the direction from `tail' (hctx_seqt) to `head' (hctx_seqh); 2) it ensures that the entire list has the length seqbufc * CCID2_SEQBUF_LEN; 3) it ensures that pipe equals the number of packets that were not marked `acked' (ccid2s_acked) between `tail' and `head'. The following argues that each of these tests is redundant, this can be verified by going through the code. (1) is not necessary, since both time and GSS increase from one packet to the next, so that subsequent insertions in tx_packet_sent (which advance the `head' pointer) will be in ascending order of time and sequence number. In (2), the length of the list is always equal to seqbufc times CCID2_SEQBUF_LEN (set to 1024) unless allocation caused an earlier failure, because: * at initialisation (tx_init), there is one chunk of size 1024 and seqbufc=1; * subsequent calls to tx_alloc_seq take place whenever head->next == tail in tx_packet_sent; then a new chunk of size 1024 is inserted between head and tail, and seqbufc is incremented by one. To show that (3) is redundant requires looking at two cases. The `pipe' variable of the TX socket is incremented only in tx_packet_sent, and decremented in tx_packet_recv. When head == tail (TX history empty) then pipe should be 0, which is the case directly after initialisation and after a retransmission timeout has occurred (ccid2_hc_tx_rto_expire). The first case involves parsing Ack Vectors for packets recorded in the live portion of the buffer, between tail and head. For each packet marked by the receiver as received (state 0) or ECN-marked (state 1), pipe is decremented by one, so for all such packets the BUG_ON in tx_check_sanity will not trigger. The second case is the loss detection in the second half of tx_packet_recv, below the comment "Check for NUMDUPACK". The first while-loop here ensures that the sequence number of `seqp' is either above or equal to `high_ack', or otherwise equal to the highest sequence number sent so far (of the entry head->prev, as head points to the next unsent entry). The next while-loop ("while (1)") counts the number of acked packets starting from that position of seqp, going backwards in the direction from head->prev to tail. If NUMDUPACK=3 such packets were counted within this loop, `seqp' points to the last acknowledged packet of these, and the "if (done == NUMDUPACK)" block is entered next. The while-loop contained within that block in turn traverses the list backwards, from head to tail; the position of `seqp' is saved in the variable `last_acked'. For each packet not marked as `acked', a congestion event is triggered within the loop, and pipe is decremented. The loop terminates when `seqp' has reached `tail', whereupon tail is set to the position previously stored in `last_acked'. Thus, between `last_acked' and the previous position of `tail', - pipe has been decremented earlier if the packet was marked as state 0 or 1; - pipe was decremented if the packet was not marked as acked. That is, pipe has been decremented by the number of packets between `last_acked' and the previous position of `tail'. As a consequence, pipe now again reflects the number of packets which have not (yet) been acked between the new position of tail (at `last_acked') and head->prev, or 0 if head==tail. The result is that the BUG_ON condition in check_sanity will also not be triggered, hence the test (3) is also redundant. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S.

* dccp ccid-3: No more CCID control blocks in LISTEN stateGerrit Renker2010-08-231-33/+7
| | | | | | | | | | | | | | | | | | | | | | | | The CCIDs are activated as last of the features, at the end of the handshake, were the LISTEN state of the master socket is inherited into the server state of the child socket. Thus, the only states visible to CCIDs now are OPEN/PARTOPEN, and the closing states. This allows to remove tests which were previously necessary to protect against referencing a socket in the listening state (in CCID-3), but which now have become redundant. As a further byproduct of enabling the CCIDs only after the connection has been fully established, several typecast-initialisations of ccid3_hc_{rx,tx}_sock can now be eliminated: * the CCID is loaded, so it is not necessary to test if it is NULL, * if it is possible to load a CCID and leave the private area NULL, then this is a bug, which should crash loudly - and earlier, * the test for state==OPEN || state==PARTOPEN now reduces only to the closing phase (e.g. when the node has received an unexpected Reset).

* | tcp: allow effective reduction of TCP's rcv-buffer via setsockoptHagen Paul Pfeifer2010-08-221-0/+11

| * | e1000e: don't check for alternate MAC addr on parts that don't support itBruce Allan2010-08-193-13/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Bruce Allan <bruce.w.allan@intel.com> The alternate MAC address feature is only supported by 80003ES2LAN and 82571 LOMs as well as a couple 82571 mezzanine cards. Checking for an alternate MAC address on other parts can fail leading to the driver not able to load. This patch limits the check for an alternate MAC address to be done only for parts that support the feature. This issue has been around since support for the feature was introduced to the e1000e driver in 2.6.34.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the e1000-devel mailing list, Nils Faerber reported latency issues with the 82573 LOM on a ThinkPad X60. It was found to be caused by ASPM L1; disabling it resolves the latency. The issue is present in kernels back to 2.6.34 and possibly 2.6.33.
