2008-11-03IPVS: Remove supports_ipv6 scheduler flagJulius Volz
Remove the 'supports_ipv6' scheduler flag since all schedulers now support IPv6. Signed-off-by: Julius Volz <julius.volz@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-03IPVS: Add IPv6 support to LBLC/LBLCR schedulersJulius Volz
Add IPv6 support to LBLC and LBLCR schedulers. These were the last schedulers without IPv6 support, but we might want to keep the supports_ipv6 flag in the case of future schedulers without IPv6 support.

Since gso_skb is re-used for qdisc_peek_dequeued(), and this skb is counted in the qdisc->q.qlen, it has to be kfreed during qdisc_reset() when qlen is zeroed. With help from David S.

2008-11-03XFRM: copy_to_user_kmaddress() reports local address twiceArnaud Ebalard
While adding support for MIGRATE/KMADDRESS in strongSwan (as specified in draft-ebalard-mext-pfkey-enhanced-migrate-00), Andreas Steffen noticed that XFRMA_KMADDRESS attribute passed to userland contains the local address twice (remote provides local address instead of remote one). This bug in copy_to_user_kmaddress() affects only key managers that use native XFRM interface (key managers that use PF_KEY are not affected). For the record, the bug was in the initial changeset I posted which added support for KMADDRESS (13c1d18931ebb5cf407cb348ef2cd6284d68902d 'xfrm: MIGRATE enhancements (draft-ebalard-mext-pfkey-enhanced-migrate)').

2008-11-02udp: Fix the SNMP counter of UDP_MIB_INERRORSWei Yongjun
UDP packets received in udpv6_recvmsg() are not only IPv6 UDP packets, but also have IPv4 UDP packets, so when do the counter of UDP_MIB_INERRORS in udpv6_recvmsg(), we should check whether the packet is a IPv6 UDP packet or a IPv4 UDP packet.

2008-11-02udp: Fix the SNMP counter of UDP_MIB_INDATAGRAMSWei Yongjun
If UDP echo is sent to xinetd/echo-dgram, the UDP reply will be received at the sender. But the SNMP counter of UDP_MIB_INDATAGRAMS will be not increased, UDP6_MIB_INDATAGRAMS will be increased instead. Endpoint A Endpoint B UDP Echo request -----------> (IPv4, Dst port=7) <---------- UDP Echo Reply (IPv4, Src port=7) This bug is come from this patch cb75994ec311b2cd50e5205efdcc0696abd6675d. It do counter UDP[6]_MIB_INDATAGRAMS until udp[v6]_recvmsg. Because xinetd used IPv6 socket to receive UDP messages, thus, when received UDP packet, the UDP6_MIB_INDATAGRAMS will be increased in function udpv6_recvmsg() even if the packet is a IPv4 UDP packet. This patch fixed the problem. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-02sch_netem: Replace ->requeue() method with open codeJarek Poplawski
After removing netem classful functionality we are sure its inner qdisc is tfifo, so we can replace qdisc->ops->requeue() method with open code. After this patch there are no more ops->requeue() users. The idea of this patch is by Patrick McHardy. Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-02sch_netem: Remove classful functionalityJarek Poplawski
Patrick McHardy noticed that: "a lot of the functionality of netem requires the inner tfifo anyways and rate-limiting is usually done on top of netem. So I would suggest so either hard-wire the tfifo qdisc or at least make the assumption that inner qdiscs are work-conserving.", and later: "- a lot of other qdiscs still don't work as inner qdiscs of netem [...]". So, according to his suggestion, this patch removes classful options of netem. The main reason of this change is to remove ops->requeue() method, which is currently used only by netem.

2008-11-01udp: add a missing smp_wmb() in udp_lib_get_port()Eric Dumazet
Corey Minyard spotted a missing memory barrier in udp_lib_get_port() We need to make sure a reader cannot read the new 'sk->sk_next' value and previous value of 'sk->sk_hash'. Or else, an item could be deleted from a chain, and inserted into another chain. If new chain was empty before the move, 'next' pointer is NULL, and lockless reader can not detect it missed following items in original chain. This patch is temporary, since we expect an upcoming patch to introduce another way of handling the problem. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2008-11-01xfrm6: handling fragmentNicolas Dichtel
RFC4301 Section 7.1 says: "7.1. Tunnel Mode SAs that Carry Initial and Non-Initial Fragments All implementations MUST support tunnel mode SAs that are configured to pass traffic without regard to port field (or ICMP type/code or Mobility Header type) values. If the SA will carry traffic for specified protocols, the selector set for the SA MUST specify the port fields (or ICMP type/code or Mobility Header type) as ANY. An SA defined in this fashion will carry all traffic including initial and non-initial fragments for the indicated Local/Remote addresses and specified Next Layer protocol(s)." But for IPv6, fragment is treated as a protocol. This change catches protocol transported in fragmented packet. In IPv4, there is no problem.

2008-11-01saner FASYNC handling on file closeAl Viro
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

2008-10-31wireless: clean up regulatory ignore_request functionJohannes Berg
This function has a few WARNs that may eventually trigger when an AP sends rogue beacons, those must be removed. Some of the comments in the function are also inappropriate as this function is concerned with the global hint, not a per- wiphy thing (which a multidomain flag on a wiphy would imply). I'm convinced that we don't need to do anything to implement multi-domain capability as 802.11-2007 specifies it because it makes only two things mandatory: * starting of BSS/IBSS must have country information (this can easily be done with a mac80211 patch) * a STA must adopt the country information (we already have the framework for this) But we don't have anything implemented anyway for now.
