2020-05-22igc: Remove igc_nfc_rule_exit()Andre Guedes
During igc_down(), we call igc_nfc_rule_exit() which traverse the NFC rule list disabling filters one by one. Later on in igc_down() flow we issue an hardware reset which also clear all filters. Since we already reset the hardware, we don't actually need to disable each filter manually. In order to simplify the code, this patch removes igc_nfc_rule() altogether.

2020-05-22igc: Change adapter->nfc_rule_lock to mutexAndre Guedes
This patch changes adapter->nfc_rule_lock type from spin_lock to mutex so we avoid unnecessary busy waiting on lock contention. A closer look at the execution context of NFC rule API users shows that all of them run in process context. The API users are: ethtool ops, igc_configure(), called when interface is brought up by user or reset workequeue thread, igc_down(), called when interface is brought down, and igc_remove(), called when driver is unloaded.

2020-05-22igc: Change return type from igc_disable_nfc_rule()Andre Guedes
None of igc_disable_nfc_rule() callers actually check its returning value. A closer look at why this function would fail shows that the only situation is when we try to delete an Ethertype or MAC filter that doesn't exist. That situation is very unlikely so we can change igc_del_etype_filter() and igc_del_mac_filter() logic to "if the filter doesn't exist, we are done", and keep the logic in igc_disable_nfc_rule() callers simple.

2020-05-22igc: Fix NFC rule validationAndre Guedes
If we try to overwrite an existing rule with the same filter but different action, we get EEXIST error as shown below. $ ethtool -N eth0 flow-type ether dst <MACADDR> action 1 loc 10 $ ethtool -N eth0 flow-type ether dst <MACADDR> action 2 loc 10 rmgr: Cannot insert RX class rule: File exists The second command is expected to overwrite the previous rule in location 10 and succeed. This patch fixes igc_ethtool_check_nfc_rule() so it also checks the rules location. In case they match, the rule under evaluation should not be considered invalid.

2020-05-22igc: Fix NFC rules leak when driver is unloadedAndre Guedes
If we have RFC rules in adapter->nfc_rule_list when the IGC driver is unloaded, all rules are leaked. This patch fixes the issue by introducing the helper igc_flush_nfc_rules() and calling it in igc_remove(). It also updates igc_set_features() so is reuses the new helper instead of re-implementing it.

2020-05-22igc: Refactor igc_ethtool_update_nfc_rule()Andre Guedes
Current implementation of igc_ethtool_update_nfc_rule() is a bit convoluted since it handles too many things: rule lookup, deletion and addition. This patch breaks it into three functions so we simplify the code and improve code reuse. Code related to rule lookup is refactored out to a new function called igc_get_nfc_rule(). Code related to rule addition is refactored out to a new function called igc_add_nfc_rule(). This function enables the rule in hardware and adds it to the adapter's list. Code related to rule deletion is refactored out to a new function called igc_del_nfc_rule(). This function disables the rule in hardware, removes it from adapter's list, and deletes it. As a byproduct of this refactoring, igc_enable_nfc_rule() and igc_disable_nfc_rule() are moved to igc_main.c since they are not used in igc_ethtool.c anymore, and igc_restore_nfc_rules() and igc_nfc_rule_ exit() are moved around to avoid forward declaration. Also, since this patch already touches igc_ethtool_get_nfc_rule(), it takes the opportunity to remove the 'match_flags' check. Empty flags are not allowed to be added so no need to check that.

2020-05-22igc: Fix NFC rules restorationAndre Guedes
When network interface is brought up, the driver re-enables the NFC rules previously configured. However, this is done in reverse order the rules were added and hardware filters are configured differently. For example, consider the following rules: $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:AA queue 0 $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:BB queue 1 $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:CC queue 2 $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:DD queue 3 RAL/RAH registers are configure so filter index 1 has address ending with AA, filter index 2 has address ending in BB, and so on. If we bring the interface down and up again, RAL/RAH registers are configured so filter index 1 has address ending in DD, filter index 2 has CC, and so on. IOW, in reverse order we had before bringing the interface down. This issue can be fixed by traversing adapter->nfc_rule_list in backwards when restoring the rules. Since hlist doesn't support backwards traversal, this patch replaces it by list_head and fixes igc_restore_nfc_rules() accordingly.

2020-05-22igc: Fix NFC rules with multicast addressesAndre Guedes
Multicast MAC addresses are valid address for NFC rules but igc_add_mac_filter() is currently rejecting them. In fact, the I225 controller doesn't impose any constraint on the address value so this patch gets rid of the address validation check in MAC filter APIs.

2020-05-22igc: Fix NFC rule overwrite casesAndre Guedes
When the 'loc' argument is passed in ethtool, the input rule overwrites any rule present in that location. In this situation we must disable the old rule otherwise it is left enabled in hardware. This patch fixes the issue by always calling igc_disable_nfc_rule() when deleting the old rule, no matter the value of 'input' argument.

The 'sw_idx' field from 'struct igc_nfc_rule' is u16 type but it is assigned an u32 value in igc_ethtool_init_nfc_rule(). This patch changes 'sw_idx' type to u32 so they match. Also, it makes more sense to call this field 'location' since it holds the NFC rule location.

2020-05-22igc: Refactor igc_ethtool_add_nfc_rule()Andre Guedes
Current implementation of igc_ethtool_add_nfc_rule() is quite long and a bit convoluted so this patch does a code refactoring to improve the code. Code related to NFC rule object initialization is refactored out to the local helper function igc_ethtool_init_nfc_rule(). Likewise, code related to NFC rule validation is refactored out to another local helper, igc_ethtool_is_nfc_rule_valid(). RX_CLS_FLOW_DISC check is removed since it is redundant. The macro is defined as the max value fsp->ring_cookie can have, so checking if fsp->ring_cookie >= adapter->num_rx_queues is already sufficient. Finally, some log messages are improved or added, and obvious comments are removed.

2020-05-21igc: Change byte order in struct igc_nfc_filterAndre Guedes
Every time we access the 'etype' and 'vlan_tci' fields from struct igc_nfc_filter to enable or disable filters in hardware we have to convert them from big endian to host order so it makes more sense to simply have these fields in host order. The byte order conversion should take place in igc_ethtool_get_nfc_ rule() and igc_ethtool_add_nfc_rule(), which are called by .get_rxnfc and .set_rxnfc ethtool ops, since ethtool subsystem is the one who deals with them in big endian order.

2020-05-21igc: Align terms used in NFC support codeAndre Guedes
The Network Flow Classification (NFC) support code from IGC driver uses terms such as 'rule', 'filter', 'entry', 'input' interchangeably when referring to NFC rules, making it harder to follow the code. This patch renames IGC's internal APIs, structs, and variables so we stick with the term 'rule' since this is the term used in ethtool APIs. It also removes some not applicable comments along the way. No functionality is changed by this patch.

This patch adds the prefix 'igc_ethtool_' to all functions defined in igc_ethtool.c so they align with the name convention already followed by other parts of the driver (e.g. igc_tsn, igc_ptp). Also, this avoids some name clashing with functions added to igc_main.c by upcoming patches in this series. No functionality is changed by this patch, just function renaming.

In igc_adapter we keep a sort of shadow copy of RAL and RAH registers. There is not much benefit in keeping it, at the cost of maintainability, since adding/removing MAC address filters is not hot path, and we already keep filters information in adapter->nfc_filter_list for cleanup and restoration purposes.

2020-05-19igc: Refactor ethertype filtering codeAndre Guedes
The whole ethertype filtering code is implemented in igc_ethtool.c and mixes logic from ethtool and core parts. This patch refactors it so core logic is moved to igc_main.c, aligning the ethertype filtering code organization with the rest of the filtering code from the driver (MAC address and VLAN priority). Besides moving code to igc_main.c, this patch also does some minor improvements to the code. Below are some highlights. In case all filters are already in use and the user tries to add another filter, we return -ENOSPC instead of -EINVAL so a more meaningful error code is provided. This also aligns with the behavior implemented in MAC address filtering code. With this code refactoring, 'etype_bitmap' array in struct igc_adapter and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore and are removed. Log messages are added to help debugging the ethertype filtering code.

2020-05-18igc: Use netdev log helpers in igc_main.cAndre Guedes
In igc_main.c we print log messages using both dev_* and netdev_* helpers, generating inconsistent output. Since this is a network device driver, we should preferably use netdev_* helpers because they append the interface name to the message, helping making sense out of the logs. This patch converts all dev_* calls to netdev_*. There is only two exceptions: 1) calls wihtin igc_probe (net_device has not been registered yet) 2) calls in igc_init_module (module initialization). It also takes this opportunity to improve some messages.
