Since commit fcc8487d ("uapi: export all headers under uapi directories"), all (and only) headers under uapi directories are exported, but asm-generic wrappers are still exceptions. To complete de-coupling the uapi from kernel headers, move generic-y of exported headers to uapi/asm/Kbuild. With this change, "make headers_install" will just need to parse uapi/asm/Kbuild to build up exported headers. Signed-off-by: NMasahiro Yamada <yamada.masahiro@socionext.com>

As Hongjun/Nicolas summarized in their original patch: " When a device changes from one netns to another, it's first unregistered, then the netns reference is updated and the dev is registered in the new netns. Thus, when a slave moves to another netns, it is first unregistered. This triggers a NETDEV_UNREGISTER event which is caught by the bonding driver. The driver calls bond_release(), which calls dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in the old netns). " This is a very special case, because the device is being unregistered no one should still care about the NETDEV_CHANGEMTU event triggered at this point, we can avoid broadcasting this event on this path, and avoid touching inetdev_event()/addrconf_notify() path. It requires to export __dev_set_mtu() to bonding driver.

There are two problems with calling sock_create_kern() from rds_tcp_accept_one() 1. it sets up a new_sock->sk that is wasteful, because this ->sk is going to get replaced by inet_accept() in the subsequent ->accept() 2. The new_sock->sk is a leaked reference in sock_graft() which expects to find a null parent->sk Avoid these problems by calling sock_create_lite().

skb maybe freed in hns_nic_net_xmit_hw() and return NETDEV_TX_OK, which cause hns_nic_net_xmit to use a freed skb. BUG: KASAN: use-after-free in hns_nic_net_xmit_hw+0x62c/0x940...

As per the SAMA5D3 device specification it supports Jumbo frames. But the suggested flag and length of bytes it supports was not updated in this driver config_structure. The maximum jumbo frames the device supports : 10240 bytes as per the device spec. While changing the MTU value greater than 1500, it threw error: sudo ifconfig eth1 mtu 9000 SIOCSIFMTU: Invalid argument Add this support to driver so that it works as expected and designed.
