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.

Do not attempt to drain the health workqueue when unloading the device in the recovery flow, this can cause a deadlock when the recovery work tries to cancel itself with sync.

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. Those WARN_ONCE are meant for debug only, and should have been inserted only under debug. We avoid such call traces by removing those WARN_ONCE.

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.

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.

While in RUNNING state, phy_state_machine() checks for link changes by comparing phydev->link before and after calling phy_read_status(). This works as long as it is guaranteed that phydev->link is never changed outside the phy_state_machine(). If in some setups this happens, it causes the state machine to miss a link loss and remain RUNNING despite phydev->link being 0. This has been observed running a dsa setup with a process continuously polling the link states over ethtool each second (SNMPD RFC-1213 agent). Disconnecting the link on a phy followed by a ETHTOOL_GSET causes dsa_slave_get_settings() / dsa_slave_get_link_ksettings() to call phy_read_status() and with that modify the link status - and with that bricking the phy state machine. This patch adds a fail-safe check while in RUNNING, which causes to move to CHANGELINK when the link is gone and we are still RUNNING.
