2007-07-10[XFRM]: Add module alias for transformation type.Masahide NAKAMURA
It is clean-up for XFRM type modules and adds aliases with its protocol: ESP, AH, IPCOMP, IPIP and IPv6 for IPsec ROUTING and DSTOPTS for MIPv6 It is almost the same thing as XFRM mode alias, but it is added new defines XFRM_PROTO_XXX for preprocessing since some protocols are defined as enum.

2007-07-10[IPV6] MIP6: Loadable module support for MIPv6.Masahide NAKAMURA
This patch makes MIPv6 loadable module named "mip6". Here is a modprobe.conf(5) example to load it automatically when user application uses XFRM state for MIPv6: alias xfrm-type-10-43 mip6 alias xfrm-type-10-60 mip6 Some MIPv6 feature is not included by this modular, however, it should not be affected to other features like either IPsec or IPv6 with and without the patch. We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt separately for future work. Loadable features: * MH receiving check (to send ICMP error back) * RO header parsing and building (i.e. RH2 and HAO in DSTOPTS) * XFRM policy/state database handling for RO These are NOT covered as loadable: * Home Address flags and its rule on source address selection * XFRM sub policy (depends on its own kernel option) * XFRM functions to receive RO as IPv6 extension header * MH sending/receiving through raw socket if user application opens it (since raw socket allows to do so) * RH2 sending as ancillary data * RH2 operation with setsockopt(2) Signed-off-by: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S.

2007-07-10[RTNETLINK]: Add nested compat attributePatrick McHardy
Add a nested compat attribute type that can be used to convert attributes that contain a structure to nested attributes in a backwards compatible way. The attribute looks like this: struct { [ compat contents ] struct rtattr { .rta_len = total size, .rta_type = type, } rta; struct old_structure struct; [ nested top-level attribute ] struct rtattr { .rta_len = nest size, .rta_type = type, } nest_attr; [ optional 0 .. n nested attributes ] struct rtattr { .rta_len = private attribute len, .rta_type = private attribute typ, } nested_attr; struct nested_data data; }; Since both userspace and kernel deal correctly with attributes that are larger than expected old versions will just parse the compat part and ignore the rest.

2007-07-10[SKBUFF]: Keep track of writable header len of headerless clonesPatrick McHardy
Currently NAT (and others) that want to modify cloned skbs copy them, even if in the vast majority of cases its not necessary because the skb is a clone made by TCP and the portion NAT wants to modify is actually writable because TCP release the header reference before cloning. The problem is that there is no clean way for NAT to find out how long the writable header area is, so this patch introduces skb->hdr_len to hold this length. When a headerless skb is cloned skb->hdr_len is set to the current headroom, for regular clones it is copied from the original. A new function skb_clone_writable(skb, len) returns whether the skb is writable up to len bytes from skb->data. To avoid enlarging the skb the mac_len field is reduced to 16 bit and the new hdr_len field is put in the remaining 16 bit. I've done a few rough benchmarks of NAT (not with this exact patch, but a very similar one). As expected it saves huge amounts of system time in case of sendfile, bringing it down to basically the same amount as without NAT, with sendmsg it only helps on loopback, probably because of the large MTU. Transmit a 1GB file using sendfile/sendmsg over eth0/lo with and without NAT: - sendfile eth0, no NAT: sys 0m0.388s - sendfile eth0, NAT: sys 0m1.835s - sendfile eth0: NAT + path: sys 0m0.370s (~ -80%) - sendfile lo, no NAT: sys 0m0.258s - sendfile lo, NAT: sys 0m2.609s - sendfile lo, NAT + patch: sys 0m0.260s (~ -90%) - sendmsg eth0, no NAT: sys 0m2.508s - sendmsg eth0, NAT: sys 0m2.539s - sendmsg eth0, NAT + patch: sys 0m2.445s (no change) - sendmsg lo, no NAT: sys 0m2.151s - sendmsg lo, NAT: sys 0m3.557s - sendmsg lo, NAT + patch: sys 0m2.159s (~ -40%) I expect other users can see a similar performance improvement, packet mangling iptables targets, ipip and ip_gre come to mind ..

2007-07-10[NET]: qdisc_restart - couple of optimizations.Krishna Kumar
Changes : - netif_queue_stopped need not be called inside qdisc_restart as it has been called already in qdisc_run() before the first skb is sent, and in __qdisc_run() after each intermediate skb is sent (note : we are the only sender, so the queue cannot get stopped while the tx lock was got in the ~LLTX case). - BUG_ON((int) q->q.qlen < 0) was a relic from old times when -1 meant more packets are available, and __qdisc_run used to loop when qdisc_restart() returned -1. During those days, it was necessary to make sure that qlen is never less than zero, since __qdisc_run would get into an infinite loop if no packets are on the queue and this bug in qdisc was there (and worse - no more skbs could ever get queue'd as we hold the queue lock too). With Herbert's recent change to return values, this check is not required. Hopefully Herbert can validate this change. If at all this is required, it should be added to skb_dequeue (in failure case), and not to qdisc_qlen. Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[NET]: qdisc_restart - readability changes plus one bug fix.Krishna Kumar
New changes : - Incorporated Peter Waskiewicz's comments. - Re-added back one warning message (on driver returning wrong value). Previous changes : - Converted to use switch/case code which looks neater. - "if (ret == NETDEV_TX_LOCKED && lockless)" is buggy, and the lockless check should be removed, since driver will return NETDEV_TX_LOCKED only if lockless is true and driver has to do the locking. In the original code as well as the latest code, this code can result in a bug where if LLTX is not set for a driver (lockless == 0) but the driver is written wrongly to do a trylock (despite LLTX being set), the driver returns LOCKED. But since lockless is zero, the packet is requeue'd instead of calling collision code which will issue warning and free up the skb. Instead this skb will be retried with this driver next time, and the same result will ensue. Removing this check will catch these driver bugs instead of hiding the problem. I am keeping this change to readability section since : a. it is confusing to check two things as it is; and b. it is difficult to keep this check in the changed 'switch' code. - Changed some names, like try_get_tx_pkt to dev_dequeue_skb (as that is the work being done and easier to understand) and do_dev_requeue to dev_requeue_skb, merged handle_dev_cpu_collision and tx_islocked to dev_handle_collision (handle_dev_cpu_collision is a small routine with only one caller, so there is no need to have two separate routines which also results in getting rid of two macros, etc. - Removed an XXX comment as it should never fail (I suspect this was related to batch skb WIP, Jamal ?). Converted some functions to original coding style of having the return values and the function name on same line, eg prio2list.

2007-07-10[CCID3]: Fix a bug in the send time processingGerrit Renker
ccid3_hc_tx_send_packet currently returns 0 when the time difference between current time and t_nom is less than 1000 microseconds. In this case the packet is sent immediately; but, unlike other packets that can be emitted on first attempt, it will not have its window counter updated and its options set as required. This is a bug. Fix: Require the time difference to be at least 1000 microseconds. The algorithm then converges: time differences > 1000 microseconds trigger the timer in dccp_write_xmit; after timer expiry this function is tried again; when the time difference is less than 1000, the packet will have its options added and window counter updated as required.

2007-07-10[TCPv4]: Improve BH latency in /proc/net/tcpHerbert Xu
Currently the code for /proc/net/tcp disable BH while iterating over the entire established hash table. Even though we call cond_resched_softirq for each entry, we still won't process softirq's as regularly as we would otherwise do which results in poor performance when the system is loaded near capacity. This anomaly comes from the 2.4 code where this was all in a single function and the local_bh_disable might have made sense as a small optimisation. The cost of each local_bh_disable is so small when compared against the increased latency in keeping it disabled over a large but mostly empty TCP established hash table that we should just move it to the individual read_lock/read_unlock calls as we do in inet_diag.

2007-07-10[TIPC]: Optimize stream send routine to avoid fragmentationAllan Stephens
This patch enhances TIPC's stream socket send routine so that it avoids transmitting data in chunks that require fragmentation and reassembly, thereby improving performance at both the sending and receiving ends of the connection. The "maximum packet size" hint that records MTU info allows the socket to decide how big a chunk it should send; in the event that the hint has become stale, fragmentation may still occur, but the data will be passed correctly and the hint will be updated in time for the following send. Note: The 66060 byte pseudo-MTU used for intra-node connections requires the send routine to perform an additional check to ensure it does not exceed TIPC"s limit of 66000 bytes of user data per chunk.

This patch simplifies TIPC's Ethernet receive routine to take advantage of information already present in each incoming sk_buff indicating whether the packet was explicitly sent to the interface, has been broadcast to all interfaces, or was picked up because the interface is in promiscous mode. This new approach also fixes the problem of TIPC accepting unwanted traffic through UML's multicast-based Ethernet interfaces (which deliver traffic in a promiscuous manner even if the interface is not configured to be promiscuous).

2007-07-10bonding / ipv6: no addrconf for slaves separately from masterJay Vosburgh
At present, when a device is enslaved to bonding, if ipv6 is active then addrconf will be initated on the slave (because it is closed then opened during the enslavement processing). This causes DAD and RS packets to be sent from the slave. These packets in turn can confuse switches that perform ipv6 snooping, causing them to incorrectly update their forwarding tables (if, e.g., the slave being added is an inactve backup that won't be used right away) and direct traffic away from the active slave to a backup slave (where the incoming packets will be dropped). This patch alters the behavior so that addrconf will only run on the master device itself. I believe this is logically correct, as it prevents slaves from having an IPv6 identity independent from the master. This is consistent with the IPv4 behavior for bonding. This is accomplished by (a) having bonding set IFF_SLAVE sooner in the enslavement processing than currently occurs (before open, not after), and (b) having ipv6 addrconf ignore UP and CHANGE events on slave devices. The eql driver also uses the IFF_SLAVE flag. I inspected eql, and I believe this change is reasonable for its usage of IFF_SLAVE, but I did not test it.
