There are some new e1000e devices can only be woken up from D3 one time, by plugging Ethernet cable. Subsequent cable plugging does set PME bit correctly, but it still doesn't get woken up. Since e1000e connects to the root complex directly, we rely on ACPI to wake it up. In this case, the GPE from _PRW only works once and stops working after that. Though it appears to be a platform bug, e1000e maintainers confirmed that I219 does not support D3. So disable runtime PM on CNP+ chips. We may need to disable earlier generations if this bug also hit older platforms. Bugzilla: https://bugzilla.kernel.org/attachment.cgi?id=280819Signed-off-by:

igb sets different WoL settings in system suspend callback and runtime suspend callback. The suspend direct complete optimization leaves igb in runtime suspended state with wrong WoL setting during system suspend. To fix this, we need to disable suspend direct complete optimization to let igb always use suspend callback to set correct WoL during system suspend. Signed-off-by:

Julian Wiedmann authored
As part of the TX completion path, qeth_release_skbs() frees the completed skbs with __skb_queue_purge(). This ends in kfree_skb(), reporting every completed skb as dropped. On the other hand when dropping an skb in .ndo_start_xmit, we end up calling consume_skb()... where we should be using kfree_skb() so that drop monitors get notified. Switch the drop/consume logic around, and also don't accumulate dropped packets in the tx_errors statistics. Fixes: dc149e37 ("s390/qeth: replace open-coded skb_queue_walk()") Signed-off-by:

The HW trap and VNICC configuration is exposed via sysfs, and may have already been modified when qeth_l?_probe_device() attempts to initialize them. So (1) initialize the VNICC values a little earlier, and (2) don't bother about the HW trap mode, it was already initialized before. Signed-off-by:

The device ID alone does not uniquely identify a device. Test both the vendor and device ID to make sure we don't mistakenly think some other vendor's 0xB410 device is a Digium HFC4S. Also, instead of the bare hex ID, use the same constant (PCI_DEVICE_ID_DIGIUM_HFC4S) used in the device ID table. No functional change intended. Signed-off-by:

Currently if the user pass an invalid asoc_id to SCTP_DEFAULT_SEND_PARAM on a TCP-style socket, it will silently ignore the new parameters. That's because after not finding an asoc, it is checking asoc_id against the known values of CURRENT/FUTURE/ALL values and that fails to match. IOW, if the user supplies an invalid asoc id or not, it should either match the current asoc or the socket itself so that it will inherit these later. Fixes it by forcing asoc_id to SCTP_FUTURE_ASSOC in case it is a TCP-style socket without an asoc, so that the values get set on the socket.

sctp_hdr(skb) only works when skb->transport_header is set properly. But in Netfilter, skb->transport_header for ipv6 is not guaranteed to be right value for sctphdr.

I am using "protocol ip" filters in TC to manipulate TC flower classifiers, which are only available with "protocol ip". However, I faced an issue that packets sent via raw sockets with ETH_P_ALL did not match the ip filters even if they did satisfy the condition (e.g., DHCP offer from dhcpd). I have determined that the behavior was caused by an unexpected value stored in skb->protocol, namely, ETH_P_ALL instead of ETH_P_IP, when packets were sent via raw sockets with ETH_P_ALL set. IMHO, storing ETH_P_ALL in skb->protocol is not appropriate for packets sent via raw sockets because ETH_P_ALL is not a real ether type used on wire, but a virtual one. This patch fixes the tx protocol selection in cases of transmission via raw sockets created with ETH_P_ALL so that it asks the driver to extract protocol from the Ethernet header.

When using fanouts with AF_PACKET, the demux functions such as fanout_demux_cpu will return an index in the fanout socket array, which corresponds to the selected socket. The ordering of this array depends on the order the sockets were added to a given fanout group, so for FANOUT_CPU this means sockets are bound to cpus in the order they are configured, which is OK. However, when stopping then restarting the interface these sockets are bound to, the sockets are reassigned to the fanout group in the reverse order, due to the fact that they were inserted at the head of the interface's AF_PACKET socket list. This means that traffic that was directed to the first socket in the fanout group is now directed to the last one after an interface restart. In the case of FANOUT_CPU, traffic from CPU0 will be directed to the socket that used to receive traffic from the last CPU after an interface restart. This commit introduces a helper to add a socket at the tail of a list, then uses it to register AF_PACKET sockets. Note that this changes the order in which sockets are listed in /proc and with sock_diag. Fixes: dc99f600 ("packet: Add fanout support") Signed-off-by:

Commit ad6c9986 ("vxlan: Fix GRO cells race condition between receive and link delete") fixed a race condition for the typical case a vxlan device is dismantled from the current netns. But if a netns is dismantled, vxlan_destroy_tunnels() is called to schedule a unregister_netdevice_queue() of all the vxlan tunnels that are related to this netns. In vxlan_destroy_tunnels(), gro_cells_destroy() is called and finished before unregister_netdevice_queue(). This means that the gro_cells_destroy() call is done too soon, for the same reasons explained in above commit. So we need to fully respect the RCU rules, and thus must remove the gro_cells_destroy() call or risk use after-free. Fixes: 58ce31cc ("vxlan: GRO support at tunnel layer") Signed-off-by:

The bug that Stan reported is as follows. After a restart, a 16-bit NIC may be incorrectly identified as a 32-bit NIC and stop working. mac8390 slot.E: Memory length resource not found, probing mac8390 slot.E: Farallon EtherMac II-C (type farallon) mac8390 slot.E: MAC 00:00:c5:30:c2:99, IRQ 61, 32 KB shared memory at 0xfeed0000, 32-bit access. The bug never arises after a cold start and only intermittently after a warm start. (I didn't investigate why the bug is intermittent.) It turns out that memcpy_toio() is deprecated and memcmp_withio() also has issues. Replacing these calls with mmio accessors fixes the problem. Reported-and-tested-by:

Similarly to commit a7603ac1 ("geneve: change NET_UDP_TUNNEL dependency to select"), GTP has a dependency on NET_UDP_TUNNEL which makes impossible to compile it if no other protocol depending on NET_UDP_TUNNEL is selected. Fix this by changing the depends to a select, and drop NET_IP_TUNNEL from the select list, as it already depends on NET_UDP_TUNNEL. Signed-off-by:
