2006-09-22[DCCP] CCID2: Fix jiffie wrap issuesAndrea Bittau
Jiffies are now handled correctly (I hope) in CCID2. If they wrap, no problem. Signed-off-by: Andrea Bittau <a.bittau@cs.ucl.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[DCCP] ackvec: Remove unused variablesAndrea Bittau
Get rid of unused variables in ackvector state. Signed-off-by: Andrea Bittau <a.bittau@cs.ucl.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[DCCP] ackvec: Fix how DCCP_ACKVEC_STATE_NOT_RECEIVED is usedAndrea Bittau
Fix the way state is masked out. DCCP_ACKVEC_STATE_NOT_RECEIVED is defined as appears in the packet, therefore bit shifting is not required. This fix allows CCID2 to correctly detect losses.

2006-09-22[DCCP] ACKVEC: fix ackvector length calculationAndrea Bittau
Fix ackvector length calculation upon receiving an "ack-of-ack". This patch avoids the ackvector from growing too large which causes it to not be inserted into packets.

2006-09-22[XFRM]: Fix wildcard as tunnel sourcePatrick McHardy
Hashing SAs by source address breaks templates with wildcards as tunnel source since the source address used for hashing/lookup is still 0/0. Move source address lookup to xfrm_tmpl_resolve_one() so we can use the real address in the lookup. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[TCP]: Send ACKs each 2nd received segment.Alexey Kuznetsov
It does not affect either mss-sized connections (obviously) or connections controlled by Nagle (because there is only one small segment in flight). The idea is to record the fact that a small segment arrives on a connection, where one small segment has already been received and still not-ACKed. In this case ACK is forced after tcp_recvmsg() drains receive buffer. In other words, it is a "soft" each-2nd-segment ACK, which is enough to preserve ACK clock even when ABC is enabled.

2006-09-22[SELINUX]: Fix bug in security_sid_mls_copyVenkat Yekkirala

2006-09-22[SCTP]: CleanupsAdrian Bunk
This patch contains the following cleanups: - make the following needlessly global function static: - socket.c: sctp_apply_peer_addr_params() - add proper prototypes for the several global functions in include/net/sctp/sctp.h Note that this fixes wrong prototypes for the following functions: - sctp_snmp_proc_exit() - sctp_eps_proc_exit() - sctp_assocs_proc_exit() The latter was spotted by the GNU C compiler and reported by David Woodhouse.

2006-09-22[IPV6] address: Support NLM_F_EXCL when adding addressesThomas Graf
iproute2 doesn't provide the NLM_F_CREATE flag when adding addresses, it is assumed to be implied. The existing code issues a check on said flag when the modify operation fails (likely due to ENOENT) before continueing to create it, this leads to a hard to predict result, therefore the NLM_F_CREATE check is removed.

2006-09-22[IPV6] address: Allow address changes while device is administrative downThomas Graf

2006-09-22[XFRM]: remove xerr_idxp from __xfrm_policy_check()James Morris
It seems that during the MIPv6 respin, some code which was originally conditionally compiled around CONFIG_XFRM_ADVANCED was accidently left in after the config option was removed. This patch removes an extraneous pointer (xerr_idxp) which is no longer needed.

2006-09-22[NET]: Fix sk->sk_filter field accessDmitry Mishin
Function sk_filter() is called from tcp_v{4,6}_rcv() functions with arg needlock = 0, while socket is not locked at that moment.

2006-09-22[TCP]: Fix rcv mss estimate for LROHerbert Xu
By passing a Linux-generated TSO packet straight back into Linux, Xen becomes our first LRO user :) Unfortunately, there is at least one spot in our stack that needs to be changed to cope with this. The receive MSS estimate is computed from the raw packet size. This is broken if the packet is GSO/LRO. Fortunately the real MSS can be found in gso_size so we simply need to use that if it is non-zero. Real LRO NICs should of course set the gso_size field in future.

2006-09-22[NETFILTER] bridge: debug message fixesStephen Hemminger

2006-09-22[NETLINK]: Improve string attribute validationThomas Graf
Introduces a new attribute type NLA_NUL_STRING to support NUL terminated strings. Attributes of this kind require to carry a terminating NUL within the maximum specified in the policy. The `old' NLA_STRING which is not required to be NUL terminated is extended to provide means to specify a maximum length of the string.

2006-09-22[UDP]: Unify UDPv4 and UDPv6 ->get_port()Gerrit Renker
This patch creates one common function which is called by udp_v4_get_port() and udp_v6_get_port(). As a result, * duplicated code is removed * udp_port_rover and local port lookup can now be removed from udp.h * further savings follow since the same function will be used by UDP-Litev4 and UDP-Litev6 In contrast to the patch sent in response to Yoshifujis comments (fixed by this variant), the code below also removes the EXPORT_SYMBOL(udp_port_rover), since udp_port_rover can now remain local to net/ipv4/udp.c.
