2016-10-20net/ncsi: Avoid if statements in ncsi_suspend_channel()Gavin Shan
There are several if/else statements in the state machine implemented by switch/case in ncsi_suspend_channel() to avoid duplicated code. It makes the code a bit hard to be understood. This drops if/else statements in ncsi_suspend_channel() to improve the code readability as Joel Stanley suggested. Also, it becomes easy to add more states in the state machine without affecting current code. No logical changes introduced by this.

SwitchX2 firmware does not implement reset done yet. Moreover, when busy-polled for ready magic, that slows down firmware and reset takes longer than the defined timeout, causing initialization to fail.

Probe functions should return 0 on success. This driver's probe returns the value returned by hci_register_dev(), which is the hci index. This works for systems with only one hci device (id = 0) but for systems where the btwilink device ends up with an id larger than 0, things will start to fall apart.

While we can ignore calls being made to non-bridge ports inside the driver, a better fix would be to push this check up to the switchdev layer. Note that these ndos can be called for non-bridged netdev, but this only happens in certain PF drivers which don't call the corresponding switchdev functions anyway.

2016-10-18bridge: multicast: restore perm router ports on multicast enableNikolay Aleksandrov
Satish reported a problem with the perm multicast router ports not getting reenabled after some series of events, in particular if it happens that the multicast snooping has been disabled and the port goes to disabled state then it will be deleted from the router port list, but if it moves into non-disabled state it will not be re-added because the mcast snooping is still disabled, and enabling snooping later does nothing. Here are the steps to reproduce, setup br0 with snooping enabled and eth1 added as a perm router (multicast_router = 2): 1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping 2. $ ip l set eth1 down ^ This step deletes the interface from the router list 3. $ ip l set eth1 up ^ This step does not add it again because mcast snooping is disabled 4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping 5. $ bridge -d -s mdb show <empty> At this point we have mcast enabled and eth1 as a perm router (value = 2) but it is not in the router list which is incorrect. After this change: 1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping 2. $ ip l set eth1 down ^ This step deletes the interface from the router list 3. $ ip l set eth1 up ^ This step does not add it again because mcast snooping is disabled 4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping 5. $ bridge -d -s mdb show router ports on br0: eth1 Note: we can directly do br_multicast_enable_port for all because the querier timer already has checks for the port state and will simply expire if it's in blocking/disabled.

2016-10-18dwc_eth_qos: do not clear pause flags from phy_device->supportedNiklas Cassel
phy_device->supported is originally set by the PHY driver. The ethernet driver should filter phy_device->supported to only contain flags supported by the IP. The IP supports setting rx and tx flow control independently, therefore SUPPORTED_Pause and SUPPORTED_Asym_Pause should not be cleared. If the flags are cleared, pause frames cannot be enabled (even if they are supported by the PHY).

Aside from that, we have: * a fix for AP_VLAN usage with the nl80211 frame command * two fixes (and two preparation patches) for A-MSDU, one to discard group-addressed (multicast) and unexpected 4-address A-MSDUs, the other to validate A-MSDU inner MAC addresses properly to prevent controlled port bypass ==================== Signed-off-by: David S.

Functions bnx2_reg_rd_ind(), bnx2_reg_wr_ind() and bnx2_ctx_wr() can be called with IRQs disabled when netconsole is enabled. So they should use spin_{,un}lock_irq{save,restore} instead of _bh variants.

Justin and Chris spotted that iptables NFLOG target was broken when they upgraded the kernel to 4.8: "ulogd-2.0.5- IPs are no longer logged" or "results in segfaults in ulogd-2.0.5". Because "struct nf_loginfo li;" is a local variable, and flags will be filled with garbage value, not inited to zero. So if it contains 0x1, packets will not be logged to the userspace anymore.
