Fix this by generalizing the generation count invalidation scheme used by ipv4. From Nicolas Dichtel. 3) When repairing TCP sockets, we need to allow to restore not just the send window scale, but the receive one too. Extend the existing interface to achieve this in a backwards compatible way. From Andrey Vagin. 4) A fix for FCOE scatter gather feature validation erroneously caused scatter gather to be disabled for things like AOE too. From Ed L Cashin. 5) Several cases of mishandling of error pointers, from Mathias Krause, Wei Yongjun, and Devendra Naga. 6) Fix gianfar build, from Richard Cochran. 7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao Hongjiang. 8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder. 9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde. 10) The removal of the conditional compilation of the clk support code in the stmmac driver broke things. This is because the interfaces used are the ones that don't also perform the enable/disable of the clk. Fix from Stefan Roese. 11) The QFQ packet scheduler can record out of range virtual start times, resulting later in misbehavior and even crashes. Fix from Paolo Valente. 12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the receiver when the advertised receive window goes to zero. Detect this case and force the processing of the IOAT DMA queue when it happens to avoid getting stuck. Fix from Michal Kubecek. 13) batman-adv assumes that test_bit() returns only 0 or 1, but this is not true for x86 (which returns -1 or 0, via the 'sbb' instruction). Fix from Linus Lussing. 14) Fix small packet corruption in e1000, from Tushar Dave. 15) make_blackhole() in the IPSEC policy code can do one read unlock too many, fix from Li RongQing. 16) The new tcp_try_coalesce() code introduced a bug in TCP URG handling, fix from Eric Dumazet. 17) Fix memory leak in __netif_receive_skb() when doing zerocopy and when hit an OOM condition. From Michael S Tsirkin. 18) netxen blindly deferences pdev->bus->self, which is not guarenteed to be non-NULL. Fix from Nikolay Aleksandrov. 19) Fix a performance regression caused by mistakes in ipv6 checksum validation in the bnx2x driver, fix from Michal Schmidt. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (45 commits) net/stmmac: Use clk_prepare_enable and clk_disable_unprepare net: change return values from -EACCES to -EPERM net/irda: sh_sir: fix return value check in sh_sir_set_baudrate() stmmac: fix return value check in stmmac_open_ext_timer() gianfar: fix phc index build failure ipv6: fix return value check in fib6_add() bnx2x: remove false warning regarding interrupt number can: ti_hecc: fix oops during rmmod can: janz-ican3: fix support for older hardware revisions net: do not disable sg for packets requiring no checksum aoe: assert AoE packets marked as requiring no checksum at91ether: return PTR_ERR if call to clk_get fails xfrm_user: don't copy esn replay window twice for new states xfrm_user: ensure user supplied esn replay window is valid xfrm_user: fix info leak in copy_to_user_tmpl() xfrm_user: fix info leak in copy_to_user_policy() xfrm_user: fix info leak in copy_to_user_state() xfrm_user: fix info leak in copy_to_user_auth() net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 tcp: restore rcv_wscale in a repair mode (v2) ...
| * net/stmmac: Use clk_prepare_enable and clk_disable_unprepareStefan Roese2012-09-212-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an issue introduced by commit ID 6a81c26f [net/stmmac: remove conditional compilation of clk code], which switched from the internal stmmac_clk_{en}{dis}able calls to clk_{en}{dis}able. By this, calling clk_prepare and clk_unprepare was removed. clk_{un}prepare is mandatory for platforms using common clock framework. Since these drivers are used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for them. Otherwise the clocks are not correctly en-/disabled and ethernet support doesn't work.

IPv6 packets are passed to the stack with CHECKSUM_NONE. The hardware obviously cannot perform IP checksum validation for IPv6, because there is no checksum in the IPv6 header.

| * | mlx4_core: Fix integer overflows so 8TBs of memory registration worksYishai Hadas2012-09-132-17/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds on the fixes done in commits 89dd86db78e0 ("mlx4_core: Allow large mlx4_buddy bitmaps") and 3de819e6b642 ("mlx4_core: Fix integer overflow issues around MTT table") so that memory registration of up to 8TB (log_num_mtt=31) finally works. It fixes integer overflows in a few mlx4_table_yyy routines in icm.c by using a u64 intermediate variable, and int/uint issues that caused table indexes to become nagive by setting some variables to be u32 instead of int. These problems cause crashes when a user attempted to register > 512GB of RAM.

This lack can cause afex to crash, and also have a slight effect on other flows (i.e., driver always assumes the Tx ring has less available buffers than what it actually has). This patch adds the missing segments, fixing said issues.

The hang should have been a NULL pointer reference had it not been for a logic error in the cdc_wdm code. commit 230718bd net: qmi_wwan: bind to both control and data interface changed qmi_wwan to use cdc_wdm as a subdriver for devices with a two-interface QMI/wwan function. The commit failed to update qmi_wwan_suspend and qmi_wwan_resume, which were written to handle either a single combined interface function, or no subdriver at all. The result was that we called into the subdriver both when the control interface was suspended and when the data interface was suspended. Calling the subdriver suspend function with an unregistered interface is not supported and will make the subdriver bug out. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

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: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before PAPRD training can run, the card needs to have sent a packet for thermal calibration. Sending a dummy packet with the PAPRD training flag set causes a crash under some circumstance. Fix the code by replacing the dummy tx with a delay that waits for a real packet tx to have occurred.
