Pull networking fixes from David Miller: 1) Fix rtlwifi crash, from Larry Finger. 2) Memory disclosure in appletalk ipddp routing code, from Vlad Tsyrklevich. 3) r8152 can erroneously split an RX packet into multiple URBs if the Rx FIFO is not empty when we suspend. Fix this by waiting for the FIFO to empty before suspending. From Hayes Wang. 4) Two GRO fixes (enter slow path when not enough SKB tail room exists, disable frag0 optimizations when there are IPV6 extension headers) from Eric Dumazet and Herbert Xu. 5) A series of mlx5e bug fixes (do source udp port offloading for tunnels properly, Ip fragment matching fixes, handling firmware errors properly when installing TC rules, etc.) from Saeed Mahameed, Or Gerlitz, Roi Dayan, Hadar Hen Zion, Gil Rockah, and Daniel Jurgens. 6) Two VRF fixes from David Ahern (don't skip multipath selection for VRF paths, disallow VRF to be configured with table ID 0). * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (35 commits) net: vrf: do not allow table id 0 net: phy: marvell: fix Marvell 88E1512 used in SGMII mode sctp: Fix spelling mistake: "Atempt" -> "Attempt" net: ipv4: Fix multipath selection with vrf cgroup: move CONFIG_SOCK_CGROUP_DATA to init/Kconfig gro: use min_t() in skb_gro_reset_offset() net/mlx5: Only cancel recovery work when cleaning up device net/mlx5e: Remove WARN_ONCE from adaptive moderation code net/mlx5e: Un-register uplink representor on nic_disable net/mlx5e: Properly handle FW errors while adding TC rules net/mlx5e: Fix kbuild warnings for uninitialized parameters net/mlx5e: Set inline mode requirements for matching on IP fragments net/mlx5e: Properly get address type of encapsulation IP headers net/mlx5e: TC ipv4 tunnel encap offload error flow fixes net/mlx5e: Warn when rejecting offload attempts of IP tunnels net/mlx5e: Properly handle offloading of source udp port for IP tunnels gro: Disable frag0 optimization on IPv6 ext headers gro: Enter slow-path if there is no tailroom mlx4: Return EOPNOTSUPP instead of ENOTSUPP net/af_iucv: don't use paged skbs for TX on HiperSockets ...

Russell King authored
When an Marvell 88E1512 PHY is connected to a nic in SGMII mode, the fiber page is used for the SGMII host-side connection. The PHY driver notices that SUPPORTED_FIBRE is set, so it tries reading the fiber page for the link status, and ends up reading the MAC-side status instead of the outgoing (copper) link. This leads to incorrect results reported via ethtool. If the PHY is connected via SGMII to the host, ignore the fiber page. However, continue to allow the existing power management code to suspend and resume the fiber page. Fixes: 6cfb3bcc ("Marvell phy: check link status in case of fiber link.")

fib_select_path does not call fib_select_multipath if oif is set in the flow struct. For VRF use cases oif is always set, so multipath route selection is bypassed. Use the FLOWI_FLAG_SKIP_NH_OIF to skip the oif check similar to what is done in fib_table_lookup. Add saddr and proto to the flow struct for the fib lookup done by the VRF driver to better match hash computation for a flow.

We now 'select SOCK_CGROUP_DATA' but Kconfig complains that this is not right when CONFIG_NET is disabled and there is no socket interface: warning: (CGROUP_BPF) selects SOCK_CGROUP_DATA which has unmet direct dependencies (NET) I don't know what the correct solution for this is, but simply removing the dependency on NET from SOCK_CGROUP_DATA by moving it out of the 'if NET' section avoids the warning and does not produce other build errors.

Also it includes some critical mlx5e TC offloads fixes from Or Gerlitz. For -stable: - net/mlx5e: Remove WARN_ONCE from adaptive moderation code Although this fix doesn't affect any functionality, I thought it is better to clean this -WARN_ONCE- up for -stable in case someone hits such corner case.

When trying to do interface down or changing interface configuration under heavy traffic, some of the adaptive moderation corner cases can occur and leave a WARN_ONCE call trace in the kernel log.

Herbert Xu authored
The GRO fast path caches the frag0 address. This address becomes invalid if frag0 is modified by pskb_may_pull or its variants. So whenever that happens we must disable the frag0 optimization. This is usually done through the combination of gro_header_hard and gro_header_slow, however, the IPv6 extension header path did the pulling directly and would continue to use the GRO fast path incorrectly. This patch fixes it by disabling the fast path when we enter the IPv6 extension header path.

Herbert Xu authored
The GRO path has a fast-path where we avoid calling pskb_may_pull and pskb_expand by directly accessing frag0. However, this should only be done if we have enough tailroom in the skb as otherwise we'll have to expand it later anyway. This patch adds the check by capping frag0_len with the skb tailroom.

With commit e5374399 ("af_iucv: use paged SKBs for big outbound messages"), we transmit paged skbs for both of AF_IUCV's transport modes (IUCV or HiperSockets). The qeth driver for Layer 3 HiperSockets currently doesn't support NETIF_F_SG, so these skbs would just be linearized again by the stack. Avoid that overhead by using paged skbs only for IUCV transport. cc stable, since this also circumvents a significant skb leak when sending large messages (where the skb then needs to be linearized).

hayeswang authored
Pause the rx and make sure the rx fifo is empty when the autosuspend occurs. If the rx data comes when the driver is canceling the rx urb, the host controller would stop getting the data from the device and continue it after next rx urb is submitted. That is, one continuing data is split into two different urb buffers. That let the driver take the data as a rx descriptor, and unexpected behavior happens.
