The race was introduced by me in commit 971316f0 ("epoll: ep_unregister_pollwait() can use the freed pwq->whead"). I did not realize that nothing can protect eventpoll after ep_poll_callback() sets ->whead = NULL, only whead->lock can save us from the race with ep_free() or ep_remove(). Move ->whead = NULL to the end of ep_poll_callback() and add the necessary barriers. TODO: cleanup the ewake/EPOLLEXCLUSIVE logic, it was confusing even before this patch.

Commit 6bc506b4 ("bridge: switchdev: Add forward mark support for stacked devices") added the 'offload_fwd_mark' bit to the skb in order to allow drivers to indicate to the bridge driver that they already forwarded the packet in L2. In case the bit is set, before transmitting the packet from each port, the port's mark is compared with the mark stored in the skb's control block. If both marks are equal, we know the packet arrived from a switch device that already forwarded the packet and it's not re-transmitted. However, if the packet is transmitted from the bridge device itself (e.g., br0), we should clear the 'offload_fwd_mark' bit as the mark stored in the skb's control block isn't valid. This scenario can happen in rare cases where a packet was trapped during L3 forwarding and forwarded by the kernel to a bridge device.

Antoine Tenart says: ==================== net: mvpp2: optional PHYs and GoP link irq This series aims at making the driver work when no PHY is connected between a port and the physical layer and not described as a fixed-phy. This is useful for some usecases such as when a switch is connected directly to the serdes lanes. It can also be used for SFP ports on the 7k-db and 8k-db while waiting for the phylink support to land in (which should be part of another series). This series makes the phy optional in the PPv2 driver, and then adds the support for the GoP port link interrupt to handle link status changes on such ports. This was tested using the SFP ports on the 7k-db and 8k-db boards. Since v1: - Now use phy_interface_mode_is_rgmii() in the GoP link patch. - Added one cosmetic patch to take advantage of phy_interface_mode_is_rgmii() in the whole PPv2 driver. ==================== Signed-off-by: David S.

This patch adds the GoP link interrupt support for when a port isn't connected to a PHY. Because of this the phylib callback is never called and the link status management isn't done.

There is not necessarily a PHY between the GoP and the physical port. However, the driver currently makes the "phy" property mandatory, contrary to what is stated in the device tree bindings. This patch makes the PHY optional, and aligns the PPv2 driver on its device tree documentation. However if a PHY is provided, the GoP link interrupt won't be used. With this patch switches directly connected to the serdes lanes and SFP ports on the Armada 8040-db and Armada 7040-db can be used if the link interrupt is described in the device tree.

Ido Schimmel authored
When the abort mechanism is invoked a default route directing packets to the CPU is programmed in all the virtual routers currently in use. This can result in packet loss in case a new VRF is configured. Upon abort, program the default route in all virtual routers, whether they are in use or not. The patch is directed at net-next since post-abort fixes aren't critical and packet loss due to a missing default route will be insignificant compared to packet loss caused by the CPU port policer.

I relied on the fact that anycast routes use the loopback device as their nexthop device to trap packets hitting them to the CPU. After commit 4832c30d ("net: ipv6: put host and anycast routes on device with address") this is no longer the case and such routes are programmed with a forward action (note the 'offload' flag): anycast cafe:: dev enp3s0np7 proto kernel metric 0 offload pref medium This will prevent the router from locally receiving packets destined to the Subnet-Router anycast address. Fix this by specifically programming anycast routes with action trap, which results in the following output: anycast cafe:: dev enp3s0np7 proto kernel metric 0 pref medium Fixes: 4832c30d ("net: ipv6: put host and anycast routes on device with address") Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the device in case a port is enslaved to a master netdev such as bridge or bond. Since the driver ignores events unrelated to its ports and their uppers, it's possible to engineer situations in which the device's data path differs from the kernel's. One example to such a situation is when a port is enslaved to a bond that is already enslaved to a bridge. When the bond was enslaved the driver ignored the event - as the bond wasn't one of its uppers - and therefore a bridge port instance isn't created in the device. Until such configurations are supported forbid them by checking that the upper device doesn't have uppers of its own.

David Ahern says: ==================== bpf: Add option to set mark and priority in cgroup sock programs Add option to set mark and priority in addition to bound device for newly created sockets. Also, allow the bpf programs to use the get_current_uid_gid helper meaning socket marks, priority and device can be set based on the uid/gid of the running process. Sample programs are updated to demonstrate the new options. v3 - no changes to Patches 1 and 2 which Alexei acked in previous versions - dropped change related to recursive programs in a cgroup - updated tests per dropped patch v2 - added flag to control recursive behavior as requested by Alexei - added comment to sock_filter_func_proto regarding use of get_current_uid_gid helper - updated test programs for recursive option ==================== Signed-off-by: David S.
