Johannes Berg says: ==================== netlink: export policy on validation failures Export the policy used for attribute validation when it fails, so e.g. for an out-of-range attribute userspace immediately gets the valid ranges back. v2 incorporates the suggestion from Jakub to have a function to estimate the size (netlink_policy_dump_attr_size_estimate()) and check that it does the right thing on the *normal* policy dumps, not (just) when calling it from the error scenario. v3 only addresses a few minor style issues. v4 fixes up a forgotten 'git add' ... sorry. v5 is a resend, I messed up v4's cover letter subject (saying v3) and apparently the second patch didn't go out at all. Tested using nl80211/iw in a few scenarios, seems to work fine and return the policy back, e.g. kernel reports: integer out of range policy: 04 00 0b 00 0c 00 04 00 01 00 00 00 00 00 00 00 ^ padding ^ minimum allowed value policy: 04 00 0b 00 0c 00 05 00 ff ff ff ff 00 00 00 00 ^ padding ^ maximum allowed value policy: 08 00 01 00 04 00 00 00 ^ type 4 == U32 for an out-of-range case. ==================== Signed-off-by: -

Add a new attribute NLMSGERR_ATTR_POLICY to the extended ACK to advertise the policy, e.g. if an attribute was out of range, you'll know the range that's permissible. Add new NL_SET_ERR_MSG_ATTR_POL() and NL_SET_ERR_MSG_ATTR_POL() macros to set this, since realistically it's only useful to do this when the bad attribute (offset) is also returned. Use it in lib/nlattr.c which practically does all the policy validation. v2: - add and use netlink_policy_dump_attr_size_estimate() v3: - remove redundant break v4: - really remove redundant break ... sorry Reviewed-by:

Field ini->smcd_version is set to SMC_V2 before calling smc_listen_ism_init(). This clears the V1 bit that may be set. When all matching ISM V2 devices fail to initialize then the smcd_version field needs to get restored to allow any possible V1 devices to initialize.

Lukas Bulwahn's patch adjusts the MAINTAINERS file, to accommodate the renaming of the mcp251xfd driver. Vincent Mailhol contributes 3 patches for the CAN networking layer. First error queue support is added the the CAN RAW protocol. The second patch converts the get_can_dlc() and get_canfd_dlc() in-Kernel-only macros from using __u8 to u8. The third patch adds a helper function to calculate the length of one bit in in multiple of time quanta. Oliver Hartkopp's patch add support for the ISO 15765-2:2016 transport protocol to the CAN stack. Three patches by Lad Prabhakar add documentation for various new rcar controllers to the device tree bindings of the rcar_can and rcan_canfd driver. Michael Walle's patch adds various processors to the flexcan driver binding documentation. The next two patches are by me and target the flexcan driver aswell. The remove the ack_grp and ack_bit from the fsl,stop-mode DT property and the driver, as they are not used anymore. As these are the last two arguments this change will not break existing device trees. The last three patches are by Srinivas Neeli and target the xilinx_can driver. The first one increases the lower limit for the bit rate prescaler to 2, the other two fix sparse and coverity findings. ==================== Signed-off-by:

A subsequent addition of an IP4 or IP6 rule after other rules would overwrite any existing TCAM entries of related L4 protocols(ex: tcp4 or udp6). This was due to the mask including too many TCAM entries. Add new packet type masks with bits properly excluded so rules are not overwritten. Signed-off-by:

While debugging a recent failure to update the flash of an ice device, I found it helpful to add additional logging which helped determine the root cause of the problem being a timeout issue. Add some extra dev_dbg() logging messages which can be enabled using the dynamic debug facility, including one for ice_aq_wait_for_event that will use jiffies to capture a rough estimate of how long we waited for the completion of a firmware command.

Currently, the devlink_port structure is stored within the ice_pf. This made sense because we create a single devlink_port for each PF. This setup does not mesh with the abstractions in the driver very well, and led to a flow where we accidentally call devlink_port_unregister twice during error cleanup. In particular, if devlink_port_register or devlink_port_unregister are called twice, this leads to a kernel panic. This appears to occur during some possible flows while cleaning up from a failure during driver probe. If register_netdev fails, then we will call devlink_port_unregister in ice_cfg_netdev as it cleans up. Later, we again call devlink_port_unregister since we assume that we must cleanup the port that is associated with the PF structure. This occurs because we cleanup the devlink_port for the main PF even though it was not allocated. We allocated the port within a per-VSI function for managing the main netdev, but did not release the port when cleaning up that VSI, the allocation and destruction are not aligned. Instead of attempting to manage the devlink_port as part of the PF structure, manage it as part of the PF VSI. Doing this has advantages, as we can match the de-allocation of the devlink_port with the unregister_netdev associated with the main PF VSI. Moving the port to the VSI is preferable as it paves the way for handling devlink ports allocated for other purposes such as SR-IOV VFs. Since we're changing up how we allocate the devlink_port, also change the indexing. Originally, we indexed the port using the PF id number. This came from an old goal of sharing a devlink for each physical function. Managing devlink instances across multiple function drivers is not workable. Instead, lets set the port number to the logical port number returned by firmware and set the index using the VSI index (sometimes referred to as VSI handle). Signed-off-by:

RDS/IB tries to refill the recv buffer in softirq context using GFP_NOWAIT flag. However alloc failure is handled by queueing a work to refill the recv buffer with GFP_KERNEL flag. This means failure to allocate with GFP_NOWAIT isn't fatal. Do not print the PAF warnings if softirq context fails to refill the recv buffer. We will see the PAF warnings when worker also fails to allocate. Signed-off-by:

Moshe Shemesh says: ==================== Add devlink reload action and limit options Introduce new options on devlink reload API to enable the user to select the reload action required and constrains limits on these actions that he may want to ensure. Complete support for reload actions in mlx5. The following reload actions are supported: driver_reinit: driver entities re-initialization, applying devlink-param and devlink-resource values. fw_activate: firmware activate. The uAPI is backward compatible, if the reload action option is omitted from the reload command, the driver reinit action will be used. Note that when required to do firmware activation some drivers may need to reload the driver. On the other hand some drivers may need to reset the firmware to reinitialize the driver entities. Therefore, the devlink reload command returns the actions which were actually performed. By default reload actions are not limited and driver implementation may include reset or downtime as needed to perform the actions. However, if reload limit is selected, the driver should perform only if it can do it while keeping the limit constraints. Reload limit added: no_reset: No reset allowed, no down time allowed, no link flap and no configuration is lost. Each driver which supports devlink reload command should expose the reload actions and limits supported. Add reload stats to hold the history per reload action per limit. For example, the number of times fw_activate has been done on this device since the driver module was added or if the firmware activation was done with or without reset. Patch 1 changes devlink_reload_supported() param type to enable using it before allocating devlink. Patch 2-3 add the new API reload action and reload limit options to devlink reload. Patch 4-5 add reload stats and remote reload stats. These stats are exposed through devlink dev get. Patches 6-11 add support on mlx5 for devlink reload action fw_activate and handle the firmware reset events. Patches 12-13 add devlink enable remote dev reset parameter and use it in mlx5. Patches 14-15 mlx5 add devlink reload limit no_reset support for fw_activate reload action. Patch 16 adds documentation file devlink-reload.rst ==================== Signed-off-by: -

On sync_reset_now event the driver does reload and PCI link toggle to activate firmware upgrade reset. When the firmware sends this event it syncs the event on all PFs, so all PFs will do PCI link toggle at once. To do PCI link toggle, the driver ensures that no other device ID under the same bridge by checking that all the PF functions under the same PCI bridge have same device ID. If no other device it uses PCI bridge link control to turn link down and up. Signed-off-by:

Once the driver gets sync_reset_request from firmware it prepares for the coming reset and sends acknowledge. After getting this event the driver expects device reset, either it will trigger PCI reset on sync_reset_now event or such PCI reset will be triggered by another PF of the same device. So it moves to reset requested mode and if it gets PCI reset triggered by the other PF it detect the reset and reloads. Signed-off-by:
