2010-02-27skbuff: align sk_buff::cb to 64 bit and close some potential holesFelix Fietkau
The alignment requirement for 64-bit load/store instructions on ARM is implementation defined. Some CPUs (such as Marvell Feroceon) do not generate an exception, if such an instruction is executed with an address that is not 64 bit aligned. In such a case, the Feroceon corrupts adjacent memory, which showed up in my tests as a crash in the rx path of ath9k that only occured with CONFIG_XFRM set. This crash happened, because the first field of the mac80211 rx status info in the cb is an u64, and changing it corrupted the skb->sp field. This patch also closes some potential pre-existing holes in the sk_buff struct surrounding the cb[] area. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: David S.

2010-02-27dev: support deferring device flag change notificationsPatrick McHardy
Split dev_change_flags() into two functions: __dev_change_flags() to perform the actual changes and __dev_notify_flags() to invoke netdevice notifiers. This will be used by rtnl_link to defer netlink notifications until the device has been fully configured. This changes ordering of some operations, in particular: - netlink notifications are sent after all changes have been performed. As a side effect this surpresses one unnecessary netlink message when the IFF_UP and other flags are changed simultaneously. - The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked after all changes have been performed. Their relative is unchanged. - net_dmaengine_put() is invoked before the NETDEV_DOWN notifier instead of afterwards. This should not make any difference since both RX and TX are already shut down at this point. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-27rtnetlink: handle rtnl_link netlink notifications manuallyPatrick McHardy
In order to support specifying device flags during device creation, we must be able to roll back device registration in case setting the flags fails without sending any notifications related to the device to userspace. This patch changes rollback_registered_many() and register_netdevice() to manually send netlink notifications for devices not handled by rtnl_link and allows to defer notifications for devices handled by rtnl_link until setup is complete.

2010-02-19nl80211: add power save commandsKalle Valo
The most needed command from nl80211, which Wireless Extensions had, is support for power save mode. Add a simple command to make it possible to enable and disable power save via nl80211. I was also planning about extending the interface, for example adding the timeout value, but after thinking more about this I decided not to do it. Basically there were three reasons: Firstly, the parameters for power save are very much hardware dependent. Trying to find a unified interface which would work with all hardware, and still make sense to users, will be very difficult. Secondly, IEEE 802.11 power save implementation in Linux is still in state of flux. We have a long way to still to go and there is no way to predict what kind of implementation we will have after few years. And because we need to support nl80211 interface a long time, practically forever, adding now parameters to nl80211 might create maintenance problems later on. Third issue are the users. Power save parameters are mostly used for debugging, so debugfs is better, more flexible, interface for this. For example, wpa_supplicant currently doesn't configure anything related to power save mode. It's better to strive that kernel can automatically optimise the power save parameters, like with help of pm qos network and other traffic parameters. Later on, when we have better understanding of power save, we can extend this command with more features, if there's a need for that.

2010-02-18net: TCP thin dupackAndreas Petlund
This patch enables fast retransmissions after one dupACK for TCP if the stream is identified as thin. This will reduce latencies for thin streams that are not able to trigger fast retransmissions due to high packet interarrival time.

This patch will make TCP use only linear timeouts if the stream is thin. This will help to avoid the very high latencies that thin stream suffer because of exponential backoff.

2010-02-16CAPI: Rework locking of controller data structuresJan Kiszka
This patch applies the mutex so far only protecting the controller list to (almost) all accesses of controller data structures. It also reworks waiting on state changes in old_capi_manufacturer so that it no longer poll and holds a module reference to the controller owner while waiting (the latter was partly done already). Modification and checking of the blocked state remains racy by design, the caller is responsible for dealing with this. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S.

2010-02-16CAPI: Rework controller state notifierJan Kiszka
Another step towards proper locking: Rework the callback provided to capidrv for controller state changes. This is so far attached to an application, which would require us to hold the corresponding lock across notification calls. But there is no direct relation between a controller up/down event and an application, so let's decouple them and provide a notifier call chain for those events instead. This notifier chain is first of all used internally. Here we request the highest priority to unsure that housekeeping work is done before any other notifications. The chain is exported via [un]register_capictr_notifier to our only user, capidrv, to replace the racy and unfixable capi20_set_callback.

2010-02-16net neigh: Decouple per interface neighbour table controls from binary sysctlsEric W. Biederman
Stop computing the number of neighbour table settings we have by counting the number of binary sysctls.

2010-02-15cfg80211/mac80211: allow registering for and sending action framesJouni Malinen
This implements a new command to register for action frames that userspace wants to handle instead of the in-kernel rejection. It is then responsible for rejecting ones that it decided not to handle. There is no unregistration, but the socket can be closed for that. Frames that are not registered for will not be forwarded to userspace and will be rejected by the kernel, the cfg80211 API helps implementing that. Additionally, this patch adds a new command that allows doing action frame transmission from userspace. It can be used either to exchange action frames on the current operational channel (e.g., with the AP with which we are currently associated) or to exchange off-channel Public Action frames with the remain-on-channel command.

with 32 bit userland and 64 bit kernels, it is unlikely but possible that insertion of new rules fails even tough there are only about 2000 iptables rules. This happens because the compat delta is using a short int. Easily reproducible via "iptables -m limit" ; after about 2050 rules inserting new ones fails with -ELOOP.
