In the current rxhash calculation function, while the sorting of the ports/addrs is coherent (you get the same rxhash for packets sharing the same 4-tuple, in both directions), ports and addrs are sorted independently. This implies packets from a connection between the same addresses but crossed ports hash to the same rxhash. For example, traffic between A=S:l and B=L:s is hashed (in both directions) from {L, S, {s, l}}. The same rxhash is obtained for packets between C=S:s and D=L:l. This patch ensures that you either swap both addrs and ports, or you swap none. Traffic between A and B, and traffic between C and D, get their rxhash from different sources ({L, S, {l, s}} for A<->B, and {L, S, {s, l}} for C<->D) The patch is co-written with Eric Dumazet <edumazet@google.com> Signed-off-by:Chema Gonzalez <chema@google.com> Signed-off-by:

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem John W. Linville says: ==================== Please pull these fixes intended for 3.6. There are more commits here than I would like -- I got a bit behind while I was stalking Steven Rostedt in San Diego last week... I'll slow it down after this! There are a couple of pulls here. One is from Johannes: "Please pull (according to the below information) to get a few fixes. * a fix to properly disconnect in the driver when authentication or association fails * a fix to prevent invalid information about mesh paths being reported to userspace * a memory leak fix in an nl80211 error path" The other comes via Gustavo: "A few updates for the 3.6 kernel. There are two btusb patches to add more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO() macro and another one that add a new device id for a Sony Vaio laptop, one fix for a user-after-free and, finally, two patches from Vinicius to fix a issue in SMP pairing." Along with those... Arend van Spriel provides a fix for a use-after-free bug in brcmfmac. Daniel Drake avoids a hang by not trying to touch the libertas hardware duing suspend if it is already powered-down. Felix Fietkau provides a batch of ath9k fixes that adress some potential problems with power settings, as well as a fix to avoid a potential interrupt storm. Gertjan van Wingerde provides a register-width fix for rt2x00, and a rt2x00 fix to prevent incorrectly detecting the rfkill status. He also provides a device ID patch. Hante Meuleman gives us three brcmfmac fixes, one that properly initializes a command structure, one that fixes a race condition that could lose usb requests, and one that removes some log spam. Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some specific devices. Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to using timers that aren't allocated when 2 wire bluetooth coexistence hardware is in use. Sergei Poselenov changes rt2800usb to do some validity checking for received packets, avoiding crashes on an ARM Soc. Stone Piao gives us an mwifiex fix for an incorrectly set skb length value for a command buffer. All of these are localized to their specific drivers, and relatively small. The power-related patches from Felix are bigger than I would like, but I merged them in consideration of their isolation to ath9k and the sensitive nature of power settings in wireless devices. ==================== Signed-off-by:

The search for promisc entries was always done on the first port, While the addition is done on the correct port. This lead to resource leackage of promisc entries on the second port and brought to a state where we could no longer enter to promiscuous mode after enough iterations of "ifconfig promisc" on the second port. Fix that by using the correct port when searching. Reported-by:

This patch fixes a bug found by Nish Aravamudan (https://lkml.org/lkml/2012/5/15/220) where the driver is not following the spec (it is not aligning the rx buffer on a 16-byte boundary) and the hypervisor aborts the registration, making the device unusable. The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461) to replace the kmalloc+map for a single call to dma_alloc_coherent() because that function always aligns to a 16-byte boundary. The stable trees will run into this bug whenever the rx buffer kmalloc call returns something not aligned on a 16-byte boundary. Cc: <stable@vger.kernel.org> Signed-off-by:

When the interface is down, the hardware is powered off. However, the suspend handler currently tries to send host sleep commands (when wakeup params are set) in this configuration, causing a system hang when going into suspend (the commands will never complete). Avoid this by detecting this situation and simply returning from the suspend handler without doing anything special. Signed-off-by:

On our system (ARM Cortex-M3 SOC running linux-2.6.33) frequent crashes were observed in the rt2800usb module because of the invalid length of the received packet (3392, 46920...). This patch adds the sanity check on the packet legth. Also, changed WARNING to ERROR in rt2x00lib_rxdone() so that the bad packet condition would be noticed.

This feature had been disabled in ath9k because the code to support it was incomplete, but now the code is in sync with the internal QCA codebase, so it's time to enable it. On many newer devices, the calibration is assumed to be done with PA linearization enabled. Tests with a particular AR933x device showed that the signal emitted at full power was highly distorted and unreliable with PA linearization disabled. With this patch, the signal becomes clear and stability is improved. Signed-off-by:
