2011-04-12cfg80211/nl80211: Add userspace authentication flag to mesh setupJavier Cardona1-0/+5
During mesh setup, use NL80211_MESH_SETUP_USERSPACE_AUTH flag to create a secure mesh and route management frames to userspace. Also, NL80211_CMD_GET_WIPHY now returns a flag NL80211_SUPPORT_MESH_AUTH if the wiphy's mesh implementation supports routing of mesh auth frames to userspace. This is useful for forward compatibility between old kernels and new userspace tools.

2011-04-12mac80211: Check for queued frames before entering power save.Vivek Natarajan1-0/+4
In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops. When power save is enabled by default and in a noisy environment, this API certainly helps in improving the average throughput.

2011-03-30net: gre: provide multicast mappings for ipv4 and ipv6Timo Teräs2-0/+24
My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device.

2011-03-24net_sched: fix THROTTLED/RUNNING raceEric Dumazet1-4/+4
commit fd245a4adb52 (net_sched: move TCQ_F_THROTTLED flag) added a race. qdisc_watchdog() is run from softirq, so special care should be taken or we can lose one state transition (THROTTLED/RUNNING) Prior to fd245a4adb52, we were manipulating q->flags (qdisc->flags &= ~TCQ_F_THROTTLED;) and this manipulation could only race with qdisc_warn_nonwc(). Since we want to avoid atomic ops in qdisc fast path - it was the meaning of commit 371121057607e (QDISC_STATE_RUNNING dont need atomic bit ops) - fix is to move THROTTLE bit into 'state' field, this one being manipulated with SMP and IRQ safe operations.

2011-03-22ipv4: fix route deletion for IPs on many subnetsJulian Anastasov1-0/+1
Alex Sidorenko reported for problems with local routes left after IP addresses are deleted. It happens when same IPs are used in more than one subnet for the device. Fix fib_del_ifaddr to restrict the checks for duplicate local and broadcast addresses only to the IFAs that use our primary IFA or another primary IFA with same address. And we expect the prefsrc to be matched when the routes are deleted because it is possible they to differ only by prefsrc. This patch prevents local and broadcast routes to be leaked until their primary IP is deleted finally from the box. As the secondary address promotion needs to delete the routes for all secondaries that used the old primary IFA, add option to ignore these secondaries from the checks and to assume they are already deleted, so that we can safely delete the route while these IFAs are still on the device list.

2011-03-21IPVS: Use global mutex in ip_vs_app.cSimon Horman1-2/+0
As part of the work to make IPVS network namespace aware __ip_vs_app_mutex was replaced by a per-namespace lock, ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes. Unfortunately this implementation results in ipvs->app_key residing in non-static storage which at the very least causes a lockdep warning. This patch takes the rather heavy-handed approach of reinstating __ip_vs_app_mutex which will cover access to the ipvs->list_head of all network namespaces.

2011-03-15[net/9p] Small non-IO PDUs for zero-copy supporting transports.Venkateswararao Jujjuri (JV)1-1/+1
If a transport prefers payload to be sent separate from the PDU (P9_TRANS_PREF_PAYLOAD_SEP), there is no need to allocate msize PDU buffers(struct p9_fcall). This patch allocates only upto 4k buffers for this kind of transports and there won't be any change to the legacy transports. Hence, this patch on top of zero copy changes allows user to specify higher msizes through the mount option without hogging the kernel heap.

2011-03-15[net/9p] Add preferences to transport layer.Venkateswararao Jujjuri (JV)1-0/+9
This patch adds preferences field to the p9_trans_module. Through this, now transport layer can express its preference about the payload. i.e if payload neds to be part of the PDU or it prefers it to be sent sepearetly so that the transport layer can handle it in a better way.

2011-03-15[net/9p] Preparation and helper functions for zero copyVenkateswararao Jujjuri (JV)1-0/+8
This patch prepares p9_fcall structure for zero copy. Added fields send the payload buffer information to the transport layer. In addition it adds a 'private' field for the transport layer to store mapped/pinned page information so that it can be freed/unpinned during req_done. This patch also creates trans_common.[ch] to house helper functions. It adds the following helper functions. p9_release_req_pages - Release pages after the transaction. p9_nr_pages - Return number of pages needed to accomodate the payload. payload_gup - Translates user buffer into kernel pages.
