Commit aca51397 ("netns: Fix arbitrary net_device-s corruptions on net_ns stop.") introduced a possibility to hit a BUG in case device is returning back to init_net and two following conditions are met: 1) dev->ifindex value is used in a name of another "dev%d" device in init_net. 2) dev->name is used by another device in init_net. Under real life circumstances this is hard to get. Therefore this has been present happily for over 10 years.

Commit d01f449c ("of_net: add NVMEM support to of_get_mac_address") added support for reading the MAC address from an nvmem-cell. This required changing the logic to return an error pointer upon failure. If stmmac is loaded before the nvmem provider driver then of_get_mac_address() return an error pointer with -EPROBE_DEFER. Propagate this error so the stmmac driver will be probed again after the nvmem provider driver is loaded. Default to a random generated MAC address in case of any other error, instead of using the error pointer as MAC address.

On initialization failure we have to delete the local fdb which was inserted due to the default pvid creation. This problem has been present since the inception of default_pvid. Note that currently there are 2 cases: 1) in br_dev_init() when br_multicast_init() fails 2) if register_netdevice() fails after calling ndo_init() This patch takes care of both since br_vlan_flush() is called on both occasions. Also the new fdb delete would be a no-op on normal bridge device destruction since the local fdb would've been already flushed by br_dev_delete(). This is not an issue for ports since nbp_vlan_init() is called last when adding a port thus nothing can fail after it.

It was reported that after resuming from suspend network fails with error "do_IRQ: 3.38 No irq handler for vector", see [0]. Enabling WoL can work around the issue, but the only actual fix is to disable MSI. So let's mimic the behavior of the vendor driver and disable MSI on all chip versions before RTL8168d.

The Dutch consumer grade ISDN network will be shut down on September 1, 2019. This means I'll be converted to some sort of VOIP shortly. At that point it would be unwise to try to maintain the gigaset driver, even for odd fixes as I do. So I'll stop maintaining it as a seperate driver and bump support to CAPI in staging. De facto this means the driver will be unmaintained, since no-one seems to be working on CAPI. I've lighty tested the hardware specific modules of this driver (bas-gigaset, ser-gigaset, and usb-gigaset) for v5.3-rc1. The basic functionality appears to be working. It's unclear whether anyone still cares. I'm aware of only one person sort of using the driver a few years ago. Thanks to Karsten Keil for the ISDN subsystems gigaset was using (I4L and CAPI). And many thanks to Hansjoerg Lipp and Tilman Schmidt for writing and upstreaming this driver. Signed-off-by:

The udp_ip4_ind bit is set only for IPv4 UDP non-fragmented packets so that the hardware can flip the checksum to 0xFFFF if the computed checksum is 0 per RFC768. However, this bit had to be set for IPv6 UDP non fragmented packets as well per hardware requirements. Otherwise, IPv6 UDP packets with computed checksum as 0 were transmitted by hardware and were dropped in the network. In addition to setting this bit for IPv6 UDP, the field is also appropriately renamed to udp_ind as part of this change.

ip4ip6/ip6ip6 tunnels run iptunnel_handle_offloads on xmit which can cause a possible use-after-free accessing iph/ipv6h pointer since the packet will be 'uncloned' running pskb_expand_head if it is a cloned gso skb.

This patch prevents a race between user invoked cached counters query and a neighbor last usage updater. The cached flow counter stats can be queried by calling "mlx5_fc_query_cached" which provides the number of bytes and packets that passed via this flow since the last time this counter was queried. It does so by reducting the last saved stats from the current, cached stats and then updating the last saved stats with the cached stats. It also provide the lastuse value for that flow. Since "mlx5e_tc_update_neigh_used_value" needs to retrieve the last usage time of encapsulation flows, it calls the flow counter query method periodically and async to user queries of the flow counter using cls_flower. This call is causing the driver to update the last reported bytes and packets from the cache and therefore, future user queries of the flow stats will return lower than expected number for bytes and packets since the last saved stats in the driver was updated async to the last saved stats in cls_flower. This causes wrong stats presentation of encapsulation flows to user. Since the neighbor usage updater only needs the lastuse stats from the cached counter, the fix is to use a dedicated lastuse query call that returns the lastuse value without synching between the cached stats and the last saved stats.

Speed translation is performed based on legacy or extended PTYS register. Translate speed with respect to: 1) Capability bit of extended PTYS table. 2) User request: a) When auto-negotiation is turned on, inspect advertisement whether it contains extended link modes. b) When auto-negotiation is turned off, speed > 100Gbps (maximal speed supported in legacy mode). With both conditions fulfilled translation is done with extended PTYS table otherwise use legacy PTYS table. Without this patch 25/50/100 Gbps speed cannot be set, since try to configure in extended mode but read from legacy mode.

When lag is active, which is controlled by the bonded mlx5e netdev, mlx5 interface unregestering must happen in the reverse order where rdma is unregistered (unloaded) first, to guarantee all references to the lag context in hardware is removed, then remove mlx5e netdev interface which will cleanup the lag context from hardware. Without this fix during destroy of LAG interface, we observed following errors: * mlx5_cmd_check:752:(pid 12556): DESTROY_LAG(0x843) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xe4ac33) * mlx5_cmd_check:752:(pid 12556): DESTROY_LAG(0x843) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xa5aee8).
