2009-11-23sctp: Remove useless last_time_used variableVlad Yasevich
The transport last_time_used variable is rather useless. It was only used when determining if CWND needs to be updated due to idle transport. However, idle transport detection was based on a Heartbeat timer and last_time_used was not incremented when sending Heartbeats. As a result the check for cwnd reduction was always true. We can get rid of the variable and just base our cwnd manipulation on the HB timer (like the code comment sais). We also have to call into the cwnd manipulation function regardless of whether HBs are enabled or not. That way we will detect idle transports if the user has disabled Heartbeats.

2009-11-23sctp: Update SWS avaoidance receiver side algorithmVlad Yasevich
We currently send window update SACKs every time we free up 1 PMTU worth of data. That a lot more SACKs then necessary. Instead, we'll now send back the actuall window every time we send a sack, and do window-update SACKs when a fraction of the receive buffer has been opened. The fraction is controlled with a sysctl.

This patch implement the sender side for SACK-IMMEDIATELY extension. Section 4.1. Sender Side Considerations Whenever the sender of a DATA chunk can benefit from the corresponding SACK chunk being sent back without delay, the sender MAY set the I-bit in the DATA chunk header.

A generic fix to this problem is to add a linkwatch_forget_dev() method to unlink the device from the list of watched devices. dev->link_watch_next becomes dev->link_watch_list (and use a bit more memory), to be able to unlink device in O(1).

2009-11-17fcntl: rename F_OWNER_GID to F_OWNER_PGRPPeter Zijlstra
This is for consistency with various ioctl() operations that include the suffix "PGRP" in their names, and also for consistency with PRIO_PGRP, used with setpriority() and getpriority(). Also, using PGRP instead of GID avoids confusion with the common abbreviation of "group ID". I'm fine with anything that makes it more consistent, and if PGRP is what is the predominant abbreviation then I see no need to further confuse matters by adding a third one.

2009-11-17mm: allow memory hotplug and hibernation in the same kernelAndi Kleen
Allow memory hotplug and hibernation in the same kernel Memory hotplug and hibernation were exclusive in Kconfig. This is obviously a problem for distribution kernels who want to support both in the same image. After some discussions with Rafael and others the only problem is with parallel memory hotadd or removal while a hibernation operation is in process. It was also working for s390 before. This patch removes the Kconfig level exclusion, and simply makes the memory add / remove functions grab the pm_mutex to exclude against hibernation. Fixes a regression - old kernels didn't exclude memory hotadd and hibernation.

2009-11-15net: Optimize hard_start_xmit() return checkingJarek Poplawski
Recent changes in the TX error propagation require additional checking and masking of values returned from hard_start_xmit(), mainly to separate cases where skb was consumed. This aim can be simplified by changing the order of NETDEV_TX and NET_XMIT codes, because the latter are treated similarly to negative (ERRNO) values. After this change much simpler dev_xmit_complete() is also used in sch_direct_xmit(), so it is moved to netdevice.h. Additionally NET_RX definitions in netdevice.h are moved up from between TX codes to avoid confusion while reading the TX comment.

2009-11-13inetpeer: Optimize inet_getid()Eric Dumazet
While investigating for network latencies, I found inet_getid() was a contention point for some workloads, as inet_peer_idlock is shared by all inet_getid() users regardless of peers. One way to fix this is to make ip_id_count an atomic_t instead of __u16, and use atomic_add_return(). In order to keep sizeof(struct inet_peer) = 64 on 64bit arches tcp_ts_stamp is also converted to __u32 instead of "unsigned long".

2009-11-13sctp: Set source addresses on the association before adding transportsVlad Yasevich
Recent commit 8da645e101a8c20c6073efda3c7cc74eec01b87f sctp: Get rid of an extra routing lookup when adding a transport introduced a regression in the connection setup. The behavior was different between IPv4 and IPv6. IPv4 case ended up working because the route lookup routing returned a NULL route, which triggered another route lookup later in the output patch that succeeded. In the IPv6 case, a valid route was returned for first call, but we could not find a valid source address at the time since the source addresses were not set on the association yet. Thus resulted in a hung connection. The solution is to set the source addresses on the association prior to adding peers.

This patch implements the NL80211_CMD_GET_SURVEY command and an get_survey() ops that a driver can implement. The goal of this command is to allow a drivers to report channel survey data (e.g. channel noise, channel occupation). For now, only the mechanism to report back channel noise has been implemented. In future, there will either be a survey-trigger command --- or the existing scan-trigger command will be enhanced. This will allow user-space to request survey for arbitrary channels. Note: any driver that cannot report channel noise should not report any value at all, e.g. made-up -92 dBm. Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: John W.

2009-11-13net: allow to propagate errors through ->ndo_hard_start_xmit()Patrick McHardy
Currently the ->ndo_hard_start_xmit() callbacks are only permitted to return one of the NETDEV_TX codes. This prevents any kind of error propagation for virtual devices, like queue congestion of the underlying device in case of layered devices, or unreachability in case of tunnels. This patches changes the NET_XMIT codes to avoid clashes with the NETDEV_TX codes and changes the two callers of dev_hard_start_xmit() to expect either errno codes, NET_XMIT codes or NETDEV_TX codes as return value. In case of qdisc_restart(), all non NETDEV_TX codes are mapped to NETDEV_TX_OK since no error propagation is possible when using qdiscs. In case of dev_queue_xmit(), the error is propagated upwards.

Tested on Savage 3D/MV card and the patch fixes the bug #11248. The frame buffer layer uses these funtions during switch between graphics and text mode of the console, but these drivers saves state before switching of the frame buffer (in the fb_open) and after releasing it (in the fb_release).
