Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to <asm-generic/socket.h> in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use. Noted in 'next' by Stephen Rothwell.

2009-09-06net_sched: reintroduce dev->qdisc for use by sch_apiPatrick McHardy
Currently the multiqueue integration with the qdisc API suffers from a few problems: - with multiple queues, all root qdiscs use the same handle. This means they can't be exposed to userspace in a backwards compatible fashion. - all API operations always refer to queue number 0. Newly created qdiscs are automatically shared between all queues, its not possible to address individual queues or restore multiqueue behaviour once a shared qdisc has been attached. - Dumps only contain the root qdisc of queue 0, in case of non-shared qdiscs this means the statistics are incomplete. This patch reintroduces dev->qdisc, which points to the (single) root qdisc from userspace's point of view. Currently it either points to the first (non-shared) default qdisc, or a qdisc shared between all queues. The following patches will introduce a classful dummy qdisc, which will be used as root qdisc and contain the per-queue qdiscs as children.

2009-09-02net/ethtool: Add support for the ethtool feature to flash firmware image ↵Ajit Khaparde
from a specified file. This patch adds support to flash a firmware image to a device using ethtool. The driver gets the filename of the firmware image and flashes the image using the request firmware path. The region "on the chip" to be flashed can be specified by an option. It is upto the device driver to enumerate the region number passed by ethtool, to the region to be flashed. The default behavior is to flash all the regions on the chip.

2009-09-02net: drop_monitor: make last_rx timestamp privateNeil Horman
It was recently pointed out to me that the last_rx field of the net_device structure wasn't updated regularly. In fact only the bonding driver really uses it currently. Since the drop_monitor code relies on the last_rx field to detect drops on recevie in hardware, We need to find a more reliable way to rate limit our drop checks (so that we don't check for drops on every frame recevied, which would be inefficient. This patch makes a last_rx timestamp that is private to the drop monitor code and is updated for every device that we track. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

After commit 2b85a34e911bf483c27cfdd124aeb1605145dc80 (net: No more expensive sock_hold()/sock_put() on each tx) sk_free() frees socks conditionally and depends on sk_wmem_alloc being set e.g. in sock_init_data().

In 5e140dfc1fe87eae27846f193086724806b33c7d "net: reorder struct Qdisc for better SMP performance" the definition of struct gnet_stats_basic changed incompatibly, as copies of this struct are shipped to userland via netlink. Restoring old behavior is not welcome, for performance reason. Fix is to use a private structure for kernel, and teach gnet_stats_copy_basic() to convert from kernel to user land, using legacy structure (struct gnet_stats_basic) Based on a report and initial patch from Michael Spang.

2009-08-14Networking: use CAP_NET_ADMIN when deciding to call request_moduleEric Paris
The networking code checks CAP_SYS_MODULE before using request_module() to try to load a kernel module. While this seems reasonable it's actually weakening system security since we have to allow CAP_SYS_MODULE for things like /sbin/ip and bluetoothd which need to be able to trigger module loads. CAP_SYS_MODULE actually grants those binaries the ability to directly load any code into the kernel. We should instead be protecting modprobe and the modules on disk, rather than granting random programs the ability to load code directly into the kernel. Instead we are going to gate those networking checks on CAP_NET_ADMIN which still limits them to root but which does not grant those processes the ability to load arbitrary code into the kernel.

2009-08-06net: Avoid enqueuing skb for default qdiscsKrishna Kumar
dev_queue_xmit enqueue's a skb and calls qdisc_run which dequeue's the skb and xmits it. In most cases, the skb that is enqueue'd is the same one that is dequeue'd (unless the queue gets stopped or multiple cpu's write to the same queue and ends in a race with qdisc_run). For default qdiscs, we can remove the redundant enqueue/dequeue and simply xmit the skb since the default qdisc is work-conserving. The patch uses a new flag - TCQ_F_CAN_BYPASS to identify the default fast queue. The controversial part of the patch is incrementing qlen when a skb is requeued - this is to avoid checks like the second line below: + } else if ((q->flags & TCQ_F_CAN_BYPASS) && !qdisc_qlen(q) && >> !q->gso_skb && + !test_and_set_bit(__QDISC_STATE_RUNNING, &q->state)) { Results of a 2 hour testing for multiple netperf sessions (1, 2, 4, 8, 12 sessions on a 4 cpu system-X).

Current neigh_periodic_timer() function is fired by timer IRQ, and scans one hash bucket each round (very litle work in fact) As we are supposed to scan whole hash table in 15 seconds, this means neigh_periodic_timer() can be fired very often. (depending on the number of concurrent hash entries we stored in this table) Converting this to a workqueue permits scanning whole table, minimizing icache pollution, and firing this work every 15 seconds, independantly of hash table size.

In order to make cfg80211/nl80211 aware of network namespaces, we have to do the following things: * del_virtual_intf method takes an interface index rather than a netdev pointer - simply change this * nl80211 uses init_net a lot, it changes to use the sender's network namespace * scan requests use the interface index, hold a netdev pointer and reference instead * we want a wiphy and its associated virtual interfaces to be in one netns together, so - we need to be able to change ns for a given interface, so export dev_change_net_namespace() - for each virtual interface set the NETIF_F_NETNS_LOCAL flag, and clear that flag only when the wiphy changes ns, to disallow breaking this invariant * when a network namespace goes away, we need to reparent the wiphy to init_net * cfg80211 users that support creating virtual interfaces must create them in the wiphy's namespace, currently this affects only mac80211 The end result is that you can now switch an entire wiphy into a different network namespace with the new command iw phy#<idx> set netns <pid> and all virtual interfaces will follow (or the operation fails).
