A previous patch added l3mdev flow update making these hooks redundant. Remove them. Signed-off-by:
-
David Ahern authored
Flip the IPv6 output path to use the l3mdev tx out hook. The VRF dst is not returned on the first FIB lookup. Instead, the dst on the skb is switched at the beginning of the IPv6 output processing to send the packet to the VRF driver on xmit. Link scope addresses (linklocal and multicast) need special handling: specifically the oif the flow struct can not be changed because we want the lookup tied to the enslaved interface. ie., the source address and the returned route MUST point to the interface scope passed in. Convert the existing vrf_get_rt6_dst to handle only link scope addresses. Signed-off-by:

Flip the IPv4 output path to use the l3mdev tx out hook. The VRF dst is not returned on the first FIB lookup. Instead, the dst on the skb is switched at the beginning of the IPv4 output processing to send the packet to the VRF driver on xmit. Signed-off-by:

Allow an L3 master device to act as the loopback for that L3 domain. For IPv4 the device can also have the address 127.0.0.1. Signed-off-by:

This patch adds the infrastructure to the output path to pass an skb to an l3mdev device if it has a hook registered. This is the Tx parallel to l3mdev_ip{6}_rcv in the receive path and is the basis for removing the existing hook that returns the vrf dst on the fib lookup. Signed-off-by: -

Add l3mdev hook to set FLOWI_FLAG_SKIP_NH_OIF flag and update oif/iif in flow struct if its oif or iif points to a device enslaved to an L3 Master device. Only 1 needs to be converted to match the l3mdev FIB rule. This moves the flow adjustment for l3mdev to a single point catching all lookups. It is redundant for existing hooks (those are removed in later patches) but is needed for missed lookups such as PMTU updates. Signed-off-by:

* The script "checkpatch.pl" can point information out like the following. WARNING: Prefer kcalloc over kzalloc with multiply Thus fix the affected source code place. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention. * Delete the local variable "size" which became unnecessary with this refactoring.

Willem noticed that we could avoid an rbtree lookup if the the attempt to coalesce incoming skb to the last skb failed for some reason. Since most ooo additions are at the tail, this is definitely worth adding a test and fast path. Suggested-by:

Saeed Mahameed says: ==================== Mellanox 100G mlx5 seamless error recovery This series from Mohamad improves the driver load/unload flows to seamlessly handle pci errors and device internal errors recovery reset flows. Current pci and internal error handling is too heavy and is done with a full restart of the driver by unregistering mlx5 interfaces (mlx5e netedevs and mlx5_ib) which will cause losing all the current interfaces and mlx5 core configurations. To improve this, we add new callback functions of mlx5 interface object (attach/detach) to be called upon reset flows when errors are detected rather than calling register and unregister interfaces. On their side, interfaces such as (mlx5e and mlx5_ib) can choose to implement those callback, if not, the old heavy reset will be called for that interface. For non-interface mlx5 modules such as sriov and eswitch, we refactored and reorganized the code in a way that the software state objects are created only once on driver load. Those software state objects are kept upon reset recovery flows and only freed once on driver unload. On seamless soft reset flows, only hardware resources are released on stop and re-allocated on start according to the current soft state. In this series only mlx5e interface implements attach/detach callbacks so that the netdevice will be kept alive on reset. On detach only hardware resources are released and the netdevice will be marked as detached to the stack. Once attached again it will re-allocate the hardware resources according to the current netdevice state, and all the configurations and the software state will be kept or restored after recovery. Note: I will be out of office all next week, in case of any updates or V2 is required, Tariq will post the new series, I hope it is ok. ==================== Signed-off-by: -

Needed to support seamless and lightweight PCI/Internal error recovery. Implement the attach/detach interface callbacks. In attach callback we only allocate HW resources. In detach callback we only deallocate HW resources. All SW/kernel objects initialzing/destroying is kept in add/remove callbacks. Signed-off-by:

Needed for lightweight and modular internal/pci error handling. Implement sriov attach function which enables pre-saved number of vfs on the device side. Implement sriov detach function which disable the current vfs on the device side. Init/cleanup function only handles sriov software context allocation and destruction. Signed-off-by:

Gather all software context creating/destroying in one function and call it once in the first load and in the last unload. load/unload functions will now receive indication if we need to create/destroy the software contexts. In internal/pci error do the unload/load flows without releasing the software objects. In this way we perserve the sw core state and it help us restoring old driver state after PCI error/shutdown.

Add attach/detach callbacks to interface API. This is crucial for implementing seamless reset flow which releases the hardware and it's resources upon detach while keeping software structures and state (e.g netdev) then reset and reallocate the hardware needed resources upon attach. Signed-off-by:

Simplify the code and makes it look modular and symmetric. Split sriov enable/disable to two levels: device level and pci level. When user enable/disable sriov (via sriov_configure driver callback) we will enable/disable both device and pci sriov. When driver load/unload we will enable/disable (on demand) only device sriov while keeping the PCI sriov enabled for next driver load. On internal/pci error, VFs will be kept enabled on PCI and the reset is done only in device level. Signed-off-by:

In case of device in internal error state there is no need to wait for vf pages since they will be reclaimed manually later in the unload flow. Signed-off-by:

Javier Martinez Canillas says: ==================== net: use IS_ENABLED() instead of checking for built-in or module This trivial series replace the open coding to check for a Kconfig symbol being built-in or module, with IS_ENABLED() macro that does exactly that.
