ipv6_cow_metrics() currently assumes only DST_HOST routes require dynamic metrics allocation from inetpeer. The assumption breaks when ndisc discovered router with RTAX_MTU and RTAX_HOPLIMIT metric. Refer to ndisc_router_discovery() in ndisc.c and note that dst_metric_set() is called after the route is created. This patch creates the metrics array (by calling dst_cow_metrics_generic) in ipv6_cow_metrics(). Test: radvd.conf: interface qemubr0 { AdvLinkMTU 1300; AdvCurHopLimit 30; prefix fd00:face:face:face::/64 { AdvOnLink on; AdvAutonomous on; AdvRouterAddr off; }; }; Before: [root@qemu1 ~]# ip -6 r show | egrep -v unreachable fd00:face:face:face::/64 dev eth0 proto kernel metric 256 expires 27sec fe80::/64 dev eth0 proto kernel metric 256 default via fe80::74df:d0ff:fe23:8ef2 dev eth0 proto ra metric 1024 expires 27sec After: [root@qemu1 ~]# ip -6 r show | egrep -v unreachable fd00:face:face:face::/64 dev eth0 proto kernel metric 256 expires 27sec mtu 1300 fe80::/64 dev eth0 proto kernel metric 256 mtu 1300 default via fe80::74df:d0ff:fe23:8ef2 dev eth0 proto ra metric 1024 expires 27sec mtu 1300 hoplimit 30 Fixes: 8e2ec639 (ipv6: don't use inetpeer to store metrics for routes.)

There is a capability which let the hw could change the settings automatically when the power change to ON. However, the USB reset would reset the settings to the hw default, so the driver has to restore the relative settings. Otherwise, it would influence the functions of the hw, and the compatibility for the USB hub and USB host controller. The relative settings are as following. - set the power down scale to 96. - enable the power saving function of USB 2.0. - disable the ALDPS of ECM mode. - set burst mode depending on the burst size. - enable the flow control of endpoint full. - set fifo empty boundary to 32448 bytes. - enable the function of exiting LPM when Rx OK occurs. - set the connect timer to 1.

If skb allocation fails once the IP header has been received, the rx state is being set to WAIT_SYNC. The logic, though, shouldn't directly return, as the buffer may contain a full packet, and therefore the WAIT_SYNC state needs to be processed (resetting state to WAIT_IP, clearing rx_buf_size and re-initializing rx_buf_missing). So, just let the while loop continue so that in the next iteration the WAIT_SYNC state cleanly stops the loop. The WAIT_SYNC processing will be done just after that, only if the end of packet is flagged. Signed-off-by:

IPv6 can keep a copy of SYN message using skb_get() in tcp_v6_conn_request() so that caller wont free the skb when calling kfree_skb() later. Therefore TCP fast open has to clone the skb it is queuing in child->sk_receive_queue, as all skbs consumed from receive_queue are freed using __kfree_skb() (ie assuming skb->users == 1) Signed-off-by:

Driver keeps adding multicast addresses without deleting removed MACs and worrying about adapters filter limit. This results into actual count of programmed multicast addresses get accumulated over the time and overruns the adapter's filter limit without putting device in ACCEPT_ALL_MULTI mode. This causes newly added multicast traffic to fail after the sequence of addition - deletion in certain pattern. This issue is seen only when netdev's mcast list count is less than adapters mcast filter limit. e.g. If adapters multicast filter limit is 38 per function then following sequence would result in multicast traffic failure for newly added MACs. - add less than 38 multicast MACs - remove previously added multicast MACs - add new multicast MACs (less than 38) Signed-off-by:Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by:

Tom Herbert says: ==================== net: Fixes to remote checksum offload and CHECKSUM_PARTIAL This patch set fixes a correctness problem with remote checksum offload, clarifies the meaning of CHECKSUM_PARTIAL, and allows remote checksum offload to set CHECKSUM_PARTIAL instead of calling csum_partial and modifying the checksum. Specifically: - In the GRO remote checksum path, restore the checksum after calling lower layer GRO functions. This is needed if the packet is forwarded off host with the Remote Checksum Offload option still present. - Clarify meaning of CHECKSUM PARTIAL in the receive path. Only the checksums referred to by checksum partial and any preceding checksums can be considered verified. - Fixes to UDP tunnel GRO complete. Need to set SKB_GSO_UDP_TUNNEL_*, SKB_GSO_TUNNEL_REMCSUM, and skb->encapsulation for forwarding case. - Infrastructure to allow setting of CHECKSUM_PARTIAL in remote checksum offload. This a potential performance benefit instead of calling csum_partial (potentially twice, once in GRO path and once in normal path). The downside of using CHECKSUM_PARTIAL and not actually writing the checksum is that we aren't verifying that the sender correctly wrote the pseudo checksum into the checksum field, or that the start/offset values actually point to a checksum. If the sender did not set up these fields correctly, a packet might be accepted locally, but not accepted by a peer when the packet is forwarded off host. Verifying these fields seems non-trivial, and because the fields can only be incorrect due to sender error and not corruption (outer checksum protects against that) we'll make use of CHECKSUM_PARTIAL the default. This behavior can be reverted as an netlink option on the encapsulation socket. - Change VXLAN and GUE to set CHECKSUM_PARTIAL in remote checksum offload by default, configuration hooks can revert to using csum_partial. Testing: I ran performance numbers using netperf TCP_STREAM and TCP_RR with 200 streams for GRE/GUE and for VXLAN. This compares before the fixes, the fixes with not setting checksum partial in remote checksum offload, and with the fixes setting checksum partial. The overall effect seems be that using checksum partial is a slight performance win, perf definitely shows a significant reduction of time in csum_partial on the receive CPUs.

This patch adds infrastructure so that remote checksum offload can set CHECKSUM_PARTIAL instead of calling csum_partial and writing the modfied checksum field. Add skb_remcsum_adjust_partial function to set an skb for using CHECKSUM_PARTIAL with remote checksum offload. Changed skb_remcsum_process and skb_gro_remcsum_process to take a boolean argument to indicate if checksum partial can be set or the checksum needs to be modified using the normal algorithm.

Properly set GSO types and skb->encapsulation in the UDP tunnel GRO complete so that packets are properly represented for GSO. This sets SKB_GSO_UDP_TUNNEL or SKB_GSO_UDP_TUNNEL_CSUM depending on whether non-zero checksums were received, and sets SKB_GSO_TUNNEL_REMCSUM if the remote checksum option was processed.

The current meaning of CHECKSUM_PARTIAL for validating checksums is that _all_ checksums in the packet are considered valid. However, in the manner that CHECKSUM_PARTIAL is set only the checksum at csum_start+csum_offset and any preceding checksums may be considered valid. If there are checksums in the packet after csum_offset it is possible they have not been verfied. This patch changes CHECKSUM_PARTIAL logic in skb_csum_unnecessary and __skb_gro_checksum_validate_needed to only considered checksums referring to csum_start and any preceding checksums (with starting offset before csum_start) to be verified.

Remote checksum offload processing is currently the same for both the GRO and non-GRO path. When the remote checksum offload option is encountered, the checksum field referred to is modified in the packet. So in the GRO case, the packet is modified in the GRO path and then the operation is skipped when the packet goes through the normal path based on skb->remcsum_offload. There is a problem in that the packet may be modified in the GRO path, but then forwarded off host still containing the remote checksum option. A remote host will again perform RCO but now the checksum verification will fail since GRO RCO already modified the checksum. To fix this, we ensure that GRO restores a packet to it's original state before returning. In this model, when GRO processes a remote checksum option it still changes the checksum per the algorithm but on return from lower layer processing the checksum is restored to its original value. In this patch we add define gro_remcsum structure which is passed to skb_gro_remcsum_process to save offset and delta for the checksum being changed. After lower layer processing, skb_gro_remcsum_cleanup is called to restore the checksum before returning from GRO. Signed-off-by:

When the RDS transport is TCP, we cannot inline the call to rds_send_xmit from rds_cong_queue_update because (a) we are already holding the sock_lock in the recv path, and will deadlock when tcp_setsockopt/tcp_sendmsg try to get the sock lock (b) cong_queue_update does an irqsave on the rds_cong_lock, and this will trigger warnings (for a good reason) from functions called out of sock_lock. This patch reverts the change introduced by 2fa57129 ("RDS: Bypass workqueue when queueing cong updates"). The patch has been verified for both RDS/TCP as well as RDS/RDMA to ensure that there are not regressions for either transport: - for verification of RDS/TCP a client-server unit-test was used, with the server blocked in gdb and thus unable to drain its rcvbuf, eventually triggering a RDS congestion update. - for RDS/RDMA, the standard IB regression tests were used Signed-off-by:Sowmini Varadhan <sowmini.varadhan@oracle.com> Signed-off-by:

This one was driving me mad, with several lines of warnings during the allmodconfig build for a single bogus pointer cast. The warning was so verbose due to the indirect macro expansion explanation, and the whole thing was just for a debug printout. The bogus pointer-to-integer cast was pointless anyway, so just remove it, and use '%p' to show the pointer. Signed-off-by:Linus Torvalds <torvalds@linux-foundation.org>
