* bnx2x: fix slowpath null crashZhu Yanjun2017-11-141-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When "NETDEV WATCHDOG: em4 (bnx2x): transmit queue 2 timed out" occurs, BNX2X_SP_RTNL_TX_TIMEOUT is set. In the function bnx2x_sp_rtnl_task, bnx2x_nic_unload and bnx2x_nic_load are executed to shutdown and open NIC. In the function bnx2x_nic_load, bnx2x_alloc_mem allocates dma failure. The message "bnx2x: [bnx2x_alloc_mem:8399(em4)]Can't allocate memory" pops out. The variable slowpath is set to NULL. When shutdown the NIC, the function bnx2x_nic_unload is called. In the function bnx2x_nic_unload, the following functions are executed. bnx2x_chip_cleanup bnx2x_set_storm_rx_mode bnx2x_set_q_rx_mode bnx2x_set_q_rx_mode bnx2x_config_rx_mode bnx2x_set_rx_mode_e2 In the function bnx2x_set_rx_mode_e2, the variable slowpath is operated. Then the crash occurs. To fix this crash, the variable slowpath is checked. And in the function bnx2x_sp_rtnl_task, after dma memory allocation fails, another shutdown and open NIC is executed.

* vxlan: fix the issue that neigh proxy blocks all icmpv6 packetsXin Long2017-11-141-18/+13
| | | | | | | | | | | | | | | | | | Commit f1fb08f6337c ("vxlan: fix ND proxy when skb doesn't have transport header offset") removed icmp6_code and icmp6_type check before calling neigh_reduce when doing neigh proxy. It means all icmpv6 packets would be blocked by this, not only ns packet. In Jianlin's env, even ping6 couldn't work through it. This patch is to bring the icmp6_code and icmp6_type check back and also removed the same check from neigh_reduce().

In order to identify a touchscreen device, Android for example, seems to already depend on INPUT_PROP_DIRECT to be present in drivers. udev still checks for either BTN_TOUCH or INPUT_PROP_DIRECT. Checking for BTN_TOUCH however can quite easily lead to false positives; it's a code that not only touchscreen device drivers use. According to the documentation, touchscreen drivers should have this property set and in order to make life easy for userspace, let's set it.
