Currently only ERP mask masked bits in key are considered for the hashtable key. That leads to false negative collisions and fallbacks to C-TCAM in case two keys differ only in delta bits. Fix this by taking full encoded key as a hashtable key, including delta bits. Reported-by:

Xin Long says: ==================== sctp: support SCTP_FUTURE/CURRENT/ALL_ASSOC This patchset adds the support for 3 assoc_id constants: SCTP_FUTURE_ASSOC SCTP_CURRENT_ASSOC, SCTP_ALL_ASSOC, described in rfc6458#section-7.2: All socket options set on a one-to-one style listening socket also apply to all future accepted sockets. For one-to-many style sockets, often a socket option will pass a structure that includes an assoc_id field. This field can be filled with the association identifier of a particular association and unless otherwise specified can be filled with one of the following constants: SCTP_FUTURE_ASSOC: Specifies that only future associations created after this socket option will be affected by this call. SCTP_CURRENT_ASSOC: Specifies that only currently existing associations will be affected by this call, and future associations will still receive the previous default value. SCTP_ALL_ASSOC: Specifies that all current and future associations will be affected by this call. The functions for many other sockopts that use assoc_id also need to be updated accordingly. ==================== Acked-by:Neil Horman <nhorman@tuxdriver.com> Signed-off-by:

Vasundhara Volam says: ==================== devlink: Add configuration parameters support for devlink_port This patchset adds support for configuration parameters setting through devlink_port. Each device registers supported configuration parameters table. The user can retrieve data on these parameters by "devlink port param show" command and can set new value to a parameter by "devlink port param set" command. All configuration modes supported by devlink_dev are supported by devlink_port also. Command examples and output: pci/0000:3b:00.0/0: name wake-on-lan type generic values: cmode permanent value false pci/0000:3b:00.1/1: name wake-on-lan type generic values: cmode permanent value false pci/0000:af:00.0/0: name wake-on-lan type generic values: cmode permanent value true pci/0000:3b:00.0/0: name wake-on-lan type generic values: cmode permanent value false There is difference of opinion on adding WOL parameter to devlink, between Jakub Kicinski and Michael Chan. Quote from Jakud Kicinski: ******** As explained previously I think it's a very bad idea to add existing configuration options to devlink, just because devlink has the ability to persist the setting in NVM. Especially that for WoL you have to get the link up so you potentially have all link config stuff as well. And that n-tuple filters are one of the WoL options, meaning we'd need the ability to persist n-tuple filters via devlink. The effort would be far better spent helping with migrating ethtool to netlink, and allowing persisting there. I have not heard any reason why devlink is a better fit. I can imagine you're just doing it here because it's less effort for you since ethtool is not yet migrated. ******** Quote from Michael Chan: ******** The devlink's WoL parameter is a persistent WoL parameter stored in the NIC's NVRAM. It is different from ethtool's WoL parameter in a number of ways. ethtool WoL is not persistent over AC power cycle and is considered OS-present WoL. As such, ethtool WoL can use a more sophisticated pattern including n-tuple with IP address in addition to the more basic types (e.g. magic packet). Whereas OS-absent power up WoL should only include magic packet and other simple types. The devlink WoL setting does not have to match the ethtool WoL setting. The card will autoneg up to the speed supported by Vaux so no special devlink link setting is needed. ******** Future expansion of WOL parameter to devlink: ******** Add an additional flag to support additional setting to address link settings. This will allow attributes to support both runtime and persistent configuration. ******** v7->v8: * Re-ordered function definitions. * Append with "Acked-by: Jiri Pirko <jiri@mellanox.com>" to first 3 patches. * Add missing devlink_port_param_driverinit_value_get() declaration. v6->v7: * Remove RFC tag from the patch-set. v5->v6: * Replace '-' with '*' in cover letter to avoid cutoff by git. v4->v5: * Added quotes from Jakub Kicinski and Michael chan on devlink's WOL parameter in the cover letter. v3->v4: * Update changes done from v2 to v3 version in individual patch descriptions. v2->v3: Make following changes as per suggestions from Jiri Pirko and Michal Kubecek. * Add a helper __devlink_params_register() with common code used by both devlink_params_register() and devlink_port_params_register(). * Define only WOL types used now and define them as bitfield, so that mutliple WOL types can be enabled upon power on. * Modify "wake-on-lan" name to "wake_on_lan" to be symmetric with previous definitions. * Rename DEVLINK_PARAM_WOL_XXX to DEVLINK_PARAM_WAKE_XXX to be symmetrical with ethtool WOL definitions. * Modify bnxt_dl_wol_validate(), to throw error message when user gives value other than DEVLINK_PARAM_WAKE_MAGIC or to disable WOL. * Use netdev_err() instead of netdev_warn(), when devlink_port_register() and devlink_port_params_register() returns error. Also, don't log rc in this message. v1->v2: Make following changes as per suggestions from Jiri Pirko. * Remove separate enum devlink_port_param_generic_id for port params. Instead club it with existing device params. Accordingly refactor remaining patchset. * Move INIT_LIST_HEAD of port param_list to devlink_port_register() * Add a helper devlink_param_verify() to be used for both devlink_params_register() and devlink_port_params_register(). * Add a helper __devlink_params_unregister() for common code in devlink_params_unregister() and devlink_port_params_unregister(). * Move DEVLINK_CMD_PORT_PARAM_XXX definitions to the end of the enum. * Split the patches for devlink_port_param_driverinit_value_get() and devlink_port_param_driverinit_value_set() into separate patches. * define DEVLINK_PARAM_GENERIC_ID_WOL type as u8 and define enum for different types of WOL. Accordingly modify bnxt_en patch to validate wol type. ==================== Signed-off-by: -

Register devlink_port with devlink and create initial port params table for bnxt_en. The table consists of a generic parameter: wake_on_lan: Enables Wake on Lan for this port when magic packet is received with this port's MAC address using ACPI pattern. If enabled, the controller asserts a wake pin upon reception of WoL packet. ACPI (Advanced Configuration and Power Interface) is an industry specification for the efficient handling of power consumption in desktop and mobile computers. v2->v3: - Modify bnxt_dl_wol_validate(), to throw error message when user gives value other than DEVLINK_PARAM_WAKE_MAGIC ot to disable WOL. - Use netdev_err() instead of netdev_warn(), when devlink_port_register() and devlink_port_params_register() returns error.

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; instance = kvzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
