While doing DOWN operation, the driver will reclaim the memory which has already used for TX. If the hardware is processing this memory, it will cause a RCB error to the hardware. According the hardware's description, the driver should reset the tqp before reclaim the memory during DOWN. Signed-off-by:

When triggering nic down, there is a time window between bringing down the protocol stack and stopping the work task. If the net is up in the time window, it may bring up the protocol stack again.

Ido Schimmel says: ==================== mlxsw: Make driver more robust In recent months we fixed several bugs in the driver that could have been avoided by re-evaluating some of the involved code paths and by introducing relevant and comprehensive test cases. This patchset tries to do that by introducing a set of small and mostly non-functional changes in addition to a new test. I have further improvements in mind, but they can be done in a different set. Patch #1 makes sure we correctly sanitize upper devices of a VLAN interface. Patch #2 removes an unexpected behavior from the driver, in which routes configured on a VLAN interface will cease being offloaded after certain operations. Patch #3 is a small cleanup. Patch #4 simplifies the driver by removing reference counting from VLAN entries configured on a port. Patches #5-#6 simplify linking/unlinking from a bridge, especially when LAG and VLAN devices are involved. They make both operations symmetric even when ports are unlinked from a bridged LAG device. Patch #7-#9 make router interface (RIF) deletion more robust by removing reliance on device chain to indicate whether a NETDEV_DOWN event in the inet{,6}addr notification chains should be processed. This is due to the fact that IP addresses can be flushed from a netdev after it was unlinked from its lower device. Patch #10 adds a new test to for valid and invalid configurations over mlxsw ports. Some of the test cases are derived from recent fixes. I expect that more test cases will be added over time. ==================== Signed-off-by: -

Add a new test that is focused on rtnetlink configuration. Its purpose is to test valid and invalid (as deemed by mlxsw) configurations and make sure that they succeed / fail without producing a trace. Some of the test cases are derived from recent fixes in order to make sure that the fixed bugs are not introduced again. Signed-off-by:

Previous patches tried to make RIF deletion more robust and avoid use-after-free situations. As another precaution, hold a reference on a RIF's netdev and release it when the RIF is deleted. Signed-off-by:
-
Ido Schimmel authored
In the past we had multiple instances where RIFs were not properly deleted. One of the reasons for leaking a RIF was that at the time when IP addresses were flushed from the respective netdev (prompting the destruction of the RIF), the netdev was no longer a mlxsw upper. This caused the inet{,6}addr notification blocks to ignore the NETDEV_DOWN event and leak the RIF. Instead of checking whether the netdev is our upper when an IP address is removed, we can instead check if the netdev has a RIF configured. To look up a RIF we need to access mlxsw private data, so the patch stores the notification blocks inside a mlxsw struct. This then allows us to use container_of() and extract the required private data. Signed-off-by: -
Ido Schimmel authored
Next patch is going to make RIF deletion more robust by removing reliance on fragile mlxsw_sp_lower_get(). This is because a netdev is not necessarily our upper anymore when its IP addresses are flushed. The inet{,6}addr notification blocks are going to resolve 'struct mlxsw_sp' using container_of(), but the functions they call still use mlxsw_sp_lower_get(). As a preparation for the next patch, propagate 'struct mlxsw_sp' down to the functions called from the notification blocks and remove reliance on mlxsw_sp_lower_get(). Signed-off-by: -

When a LAG device or a VLAN device on top of it is enslaved to a bridge, the driver propagates the CHANGEUPPER event to the LAG's slaves. This causes each physical port to increase the reference count of the internal representation of the bridge port by calling mlxsw_sp_port_bridge_join(). However, when a port is removed from a LAG, the corresponding leave() function is not called and the reference count is not decremented. This leads to ugly hacks such as mlxsw_sp_bridge_port_should_destroy() that try to understand if the bridge port should be destroyed even when its reference count is not 0. Instead, make sure that when a port is unlinked from a LAG it would see the same events as if the LAG (or its uppers) were unlinked from a bridge. The above is achieved by walking the LAG's uppers when a port is unlinked and calling mlxsw_sp_port_bridge_leave() for each upper that is enslaved to a bridge. Signed-off-by:

Commit b3529af6 ("spectrum: Reference count VLAN entries") started reference counting port-VLAN entries in a similar fashion to the 8021q driver. However, this is not actually needed and only complicates things. Instead, the driver should forbid the creation of a VLAN on a port if this VLAN already exists. This would also solve the issue fixed by the mentioned commit. Therefore, remove the get()/put() API and use create()/destroy() instead. One place that needs special attention is VLAN addition in a VLAN-aware bridge via switchdev operations. In case the VLAN flags (e.g., 'pvid') are toggled, then the VLAN entry already exists. To prevent the driver from wrongly returning EEXIST, the driver is changed to check in the prepare phase whether the entry already exists and only returns an error in case it is not associated with the correct bridge port.

In commit 993107fe ("mlxsw: spectrum_switchdev: Fix VLAN device deletion via ioctl") I fixed a bug caused by the fact that the driver views differently the deletion of a VLAN device when it is deleted via an ioctl and netlink. Instead of relying on a specific order of events (device being unregistered vs. VLAN filter being updated), simply make sure that the driver performs the necessary cleanup when the VLAN device is unlinked, which always happens before the other two events.

Currently, when a RIF is constructed on top of a FID, the RIF increments the FID's reference count and the RIF is destroyed when the FID's reference count drops to 1. This effectively means that when no local ports are member in the FID, the FID is destroyed regardless if the router port is a member in the FID or not. The above can lead to the unexpected behavior in which routes using a VLAN interface as their nexthop device are no longer offloaded after the last local port leaves the corresponding VLAN (FID). Example: # ip -4 route show dev br0.10 192.0.2.0/24 proto kernel scope link src 192.0.2.1 offload # bridge vlan del vid 10 dev swp3 # ip -4 route show dev br0.10 192.0.2.0/24 proto kernel scope link src 192.0.2.1 After the patch, the route is offloaded before and after the VLAN is removed from local port 'swp3', as the RIF corresponding to 'br0.10' continues to exists. In order to remove RIFs' reliance on the underlying FID's reference count, we need to add a reference count to sub-port RIFs, which are RIFs that correspond to physical ports and their uppers (e.g., LAG devices). In this case, each {Port, VID} ('struct mlxsw_sp_port_vlan') needs to hold a reference on the RIF. For example: bond0.10 | bond0 | +-------+ | | swp1 swp2 Both {Port 1, VID 10} and {Port 2, VID 10} will hold a reference on the RIF corresponding to 'bond0.10'. When the last reference is dropped, the RIF will be destroyed. Signed-off-by: -

Currently, only VRF and macvlan uppers are supported on top of VLAN device configured over a bridge, so make sure the driver forbids other uppers. Note that enslavement to a VRF is handled earlier in the notification block, so there is no need to check for a VRF upper here. Signed-off-by:

Tuong Lien says: ==================== tipc: tracepoints and trace_events in TIPC The patch series is the first step of introducing a tracing framework in TIPC, which will assist in collecting complete & plentiful data for post analysis, even in the case of a single failure occurrence e.g. when the failure is unreproducible. The tracing code in TIPC utilizes the powerful kernel tracepoints, trace events features along with particular dump functions to trace the TIPC object data and events (incl. bearer, link, socket, node, etc.). The tracing code should generate zero-load to TIPC when the trace events are not enabled. ==================== Signed-off-by: -
