The function tipc_report_overlap() is called from the binding table with numerous parameters taken from an instance of struct publication. A closer look reveals that it always is safe to send along a pointer to the instance itself, and hence reduce the call signature. We do that in this commit. Signed-off-by:

We reduce the signature of tipc_find_service() and tipc_create_service(). The reason for doing this might not be obvious, but we plan to let struct tipc_uaddr contain information that is relevant for these functions in a later commit. Signed-off-by:

We reduce the signature of tipc_nametbl_lookup_group() by using a struct tipc_uaddr pointer. This entails a couple of minor changes in the functions tipc_send_group_mcast/anycast/unicast/bcast() in socket.c Signed-off-by:

We simplify the signature if function tipc_nametbl_lookup_anycast(), using address structures instead of discrete integers. This also makes it possible to make some improvements to the functions __tipc_sendmsg() in socket.c and tipc_msg_lookup_dest() in msg.c. Signed-off-by:

The binding table provides four different lookup functions, which purpose is not obvious neither by their names nor by the (lack of) descriptions. We now give these functions names that better match their purposes, and improve the comments that describe what they are doing. Signed-off-by:

We introduce a simplified version of struct sockaddr_tipc, using anonymous unions and structures. Apart from being nicer to work with, this struct will come in handy when we in a later commit add another address type. Signed-off-by:

We instantiate struct publication in tipc_nametbl_insert_publ() instead of as currently in tipc_service_insert_publ(). This has the advantage that we can pass a pointer to the publication struct to the next call levels, instead of the numerous individual parameters we pass on now. It also gives us a location to keep the contents of the additional fields we will introduce in a later commit. Signed-off-by:
-
Jon Maloy authored
In a future commit we will introduce more members to struct publication. In order to keep this structure comprehensible we now group some of its current fields into the sub-structures where they really belong, - A struct tipc_service_range for the functional address the publication is representing. - A struct tipc_socket_addr for the socket bound to that service range. We also rename the stack variable 'publ' to just 'p' in a few places. This is just as easy to understand in the given context, and keeps the number of wrapped code lines to a minimum. There are no functional changes in this commit. Signed-off-by:

Alexander Duyck says: ==================== ethtool: Factor out common code related to writing ethtool strings This patch set is meant to be a cleanup and refactoring of common code bits from several drivers. Specificlly a number of drivers engage in a pattern where they will use some variant on an sprintf or memcpy to write a string into the ethtool string array and then they will increment their pointer by ETH_GSTRING_LEN. Instead of having each driver implement this independently I am refactoring the code so that we have one central function, ethtool_sprintf that does all this and takes a double pointer to access the data, a formatted string to print, and the variable arguments that are associated with the string. Changes from v1: Fixed usage of char ** vs unsigned char ** in hisilicon drivers Changes from RFC: Renamed ethtool_gsprintf to ethtool_sprintf Fixed reverse xmas tree issue in patch 2 ==================== Reviewed-by:

Update the bnad_get_strings to make use of ethtool_sprintf and avoid unnecessary line wrapping. To do this we invert the logic for the string set test and instead exit immediately if we are not working with the stats strings. In addition the function is broken up into subfunctions for each area so that we can simply call ethtool_sprintf once for each string in a given subsection. Signed-off-by:

So this patch actually does 3 things. First it removes a stray white space at the start of the variable declaration in vmxnet3_get_strings. Second it flips the logic for the string test so that we exit immediately if we are not looking for the stats strings. Doing this we can avoid unnecessary indentation and line wrapping. Then finally it updates the code to use ethtool_sprintf rather than a memcpy and pointer increment to write the ethtool strings. Signed-off-by:

Update the code to replace instances of snprintf and a pointer update with just calling ethtool_sprintf. Also replace the char pointer with a u8 pointer to avoid having to recast the pointer type. Acked-by:

The nfp_pr_et function is nearly identical to ethtool_sprintf except for the fact that it passes the pointer by value and as a return whereas ethtool_sprintf passes it as a pointer. Since they are so close just update nfp to make use of ethtool_sprintf Reviewed-by:

Alexander Duyck authored
Add a function to handle the common pattern of printing a string into the ethtool strings interface and incrementing the string pointer by the ETH_GSTRING_LEN. Most of the drivers end up doing this and several have implemented their own versions of this function so it would make sense to consolidate on one implementation. Signed-off-by:

Saeed Mahameed says: ==================== mlx5-updates-2021-03-16 mlx5 uplink representor netdev persistence. Before this patchset we used to have separate netdevs for Native NIC mode and Switchdev mode (uplink representor netdev), meaning that if user switches modes between Native to Switchdev and vice versa, the driver would cleanup the current netdev representor and create a new one for the new mode, such behavior created an administrative nightmare for users, where users need to be aware of such loss of both data path and control path configurations, e.g. netdev attributes and arp/route tables, where the later is more painful. A simple solution for this is not to replace the netdev in first place and use a single netdev to serve the uplink/physical port whether it is in switchdev mode or native mode. We already have different HW profiles for each netdev mode, in this series we just replace the HW profile on the fly and we keep the same netdev attached. Refactoring: Some refactoring has been made to overcome some technical difficulties 1) The netdev is created with the maximum amount of tx/rx queues to serve the two profiles. 2) Some ndos are not supported in some modes, so we added a mode check for such cases, e.g legacy sriov ndos must be blocked in switchdev mode. 3) Some mlx5 netdev private attributes need to be moved out of profiles and kept in a persistent place, where the netdev is created e.g devlink port and other global HW resources 4) The netdev devlink port is now always registered with the switch id Implementation: the last three patches implement the mechanism now as the netdev can be shared. 5) Don't recreate the netdev on switchdev mode changes 6) Prevent changing switchdev mode when some netdev operations are active, mostly when TC rules are being processed. This is required since the netdev is kept registered while switchdev mode can be changed. ==================== Signed-off-by:

E-Switch mode change routine will take the write lock to prevent any consumer to access the E-Switch resources while E-Switch is going through a mode change. In the next patch E-Switch consumers (e.g vport representors) will take read_lock prior to accessing E-Switch resources to prevent E-Switch mode changing in the middle of the operation.

When we clean all the interfaces, i.e. rescan or reload module, we need to clean eth-reps devices first, before eth devices. We will re-use the native NIC port net device instance for the Uplink representor. Changing eswitch mode will skip destroying the eth device so the net device won't be destroyed and only change the profile. Creating uplink eth-rep will initialize the representor related resources. In that sense when we destroy all devices we first need to destroy eth-rep devices so uplink eth-rep will clean all representor related resources and only then destroy the eth device which will destroy rest of the resources and the net device.

We will re-use the native NIC port net device instance for the Uplink representor. While changing profiles private resources are not available but some ndos are not checking if the netdev is present.
