2016-08-15mlxsw: spectrum_router: Fix use after freeVincent
In mlxsw_sp_router_fib4_add_info_destroy(), the fib_entry pointer is used after it has been freed by mlxsw_sp_fib_entry_destroy(). Use a temporary variable to fix this.

2016-08-13net: remove type_check from dev_get_nest_level()Sabrina Dubroca
The idea for type_check in dev_get_nest_level() was to count the number of nested devices of the same type (currently, only macvlan or vlan devices). This prevented the false positive lockdep warning on configurations such as: eth0 <--- macvlan0 <--- vlan0 <--- macvlan1 However, this doesn't prevent a warning on a configuration such as: eth0 <--- macvlan0 <--- vlan0 eth1 <--- vlan1 <--- macvlan1 In this case, all the locks end up with a nesting subclass of 1, so lockdep thinks that there is still a deadlock: - in the first case we have (macvlan_netdev_addr_lock_key, 1) and then take (vlan_netdev_xmit_lock_key, 1) - in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then take (macvlan_netdev_addr_lock_key, 1) By removing the linktype check in dev_get_nest_level() and always incrementing the nesting depth, lockdep considers this configuration valid.

2016-08-11macsec: use after free when deleting the underlying deviceSabrina Dubroca
macsec_notify() loops over the list of macsec devices configured on the underlying device when this device is being removed. This list is part of the rx_handler data. However, macsec_dellink unregisters the rx_handler and frees the rx_handler data when the last macsec device is removed from the underlying device. Add macsec_common_dellink() to delete macsec devices without unregistering the rx_handler and freeing the associated data.

2016-08-09dm9000: Fix irq trigger type setup on non-dt platformsSylwester Nawrocki
Commit b5a099c67a1c36b "net: ethernet: davicom: fix devicetree irq resource" causes an interrupt storm after the ethernet interface is activated on S3C24XX platform (ARM non-dt), due to the interrupt trigger type not being set properly. It seems, after adding parsing of IRQ flags in commit 7085a7401ba54e92b "drivers: platform: parse IRQ flags from resources", there is no path for non-dt platforms where irq_set_type callback could be invoked when we don't pass the trigger type flags to the request_irq() call. In case of a board where the regression is seen the interrupt trigger type flags are passed through a platform device's resource and it is not currently handled properly without passing the irq trigger type flags to the request_irq() call. In case of OF an of_irq_get() call within platform_get_irq() function seems to be ensuring required irq_chip setup, but there is no equivalent code for non OF/ACPI platforms. This patch mostly restores irq trigger type setting code which has been removed in commit ("net: ethernet: davicom: fix devicetree irq resource").

This patch fixes a data structure corruption bug in the SRIOV VF mailbox handler code. While handling mailbox commands from the atomic context, driver is accessing and updating qlcnic_async_work_list_struct entry fields in the async work list. These fields could be concurrently accessed by the work function resulting in data corruption. This patch restructures async mbx command handling by using a separate async command list instead of using a list of work_struct structures. A single work_struct is used to schedule and handle the async commands with proper locking mechanism.

2016-08-02w1:omap_hdq: fix regressionH. Nikolaus Schaller
Commit e93762bbf681 ("w1: masters: omap_hdq: add support for 1-wire mode") added a statement to clear the hdq_irqstatus flags in hdq_read_byte(). If the hdq reading process is scheduled slowly or interrupts are disabled for a while the hardware read activity might already be finished on entry of hdq_read_byte(). And hdq_isr() already has set the hdq_irqstatus to 0x6 (can be seen in debug mode) denoting that both, the TXCOMPLETE and RXCOMPLETE interrupts occurred in parallel. This means there is no need to wait and the hdq_read_byte() can just read the byte from the hdq controller. By resetting hdq_irqstatus to 0 the read process is forced to be always waiting again (because the if statement always succeeds) but the hardware will not issue another RXCOMPLETE interrupt. This results in a false timeout. After such a situation the hdq bus hangs. Link: http://lkml.kernel.org/r/b724765f87ad276a69625bc19806c8c8844c4590.1469513669.git.hns@goldelico.com Signed-off-by: H.
