In preparation for new firmware APIs to allocate hardware resources, add a new struct bnxt_hw_resc to hold various min, max and reserved resources. This new structure is common for PFs and VFs.

After SRIOV has been enabled and disabled, the MSIX vectors assigned to the VFs have to be re-initialized. Otherwise they cannot be re-used by the PF. For example, increasing the number of PF rings after disabling SRIOV may fail if the PF uses MSIX vectors previously assigned to the VFs. To fix this, we add logic in bnxt_restore_pf_fw_resources() to close the NIC, clear and re-init MSIX, and re-open the NIC.

Currently in the cases where cmp_type == CMP_TYPE_RX_L2_TPA_START_CMP or CMP_TYPE_RX_L2_TPA_END_CMP the exit path updates cpr->rx_bytes with an uninitialized length len.

In bnxt_vf_ndo_prep (which is called by bnxt_get_vf_config ndo), there is a check for "Invalid VF id". Currently, the check is done against max_vfs. However, the user doesn't always create max_vfs. So, the check should be against the created number of VFs. The number of bnxt_vf_info structures that are allocated in bnxt_alloc_vf_resources routine is the "number of requested VFs". So, if an "invalid VF id" falls between the requested number of VFs and the max_vfs, the driver will be dereferencing an invalid pointer. Fixes: c0c050c5 ("bnxt_en: New Broadcom ethernet driver.")

Most callers of rhashtable_walk_start don't care about a resize event which is indicated by a return value of -EAGAIN. So calls to rhashtable_walk_start are wrapped wih code to ignore -EAGAIN. Something like this is common: ret = rhashtable_walk_start(rhiter); if (ret && ret != -EAGAIN) goto out; Since zero and -EAGAIN are the only possible return values from the function this check is pointless. The condition never evaluates to true. This patch changes rhashtable_walk_start to return void. This simplifies code for the callers that ignore -EAGAIN. For the few cases where the caller cares about the resize event, particularly where the table can be walked in mulitple parts for netlink or seq file dump, the function rhashtable_walk_start_check has been added that returns -EAGAIN on a resize event.

On some dual port NICs, the 2 ports have to be configured with compatible link speeds. Under some conditions, a port's configured speed may no longer be supported. The firmware will send a message to the driver when this happens. Improve this logic that prints out the warning by only printing it if we can determine the link speed that is no longer supported. If the speed is unknown or it is in autoneg mode, skip the warning message.

The current 'bnxt_shutdown' implementation only invokes 'bnxt_ulp_shutdown' to shut down RoCE in the case when the system is in the path of power off (SYSTEM_POWER_OFF). While this may work in most cases, it does not work in the smart NIC case, when Linux 'reboot' command is initiated from the Linux that runs on the ARM cores of the NIC card. In this particular case, Linux 'reboot' results in a system 'L3' level reset where the entire ARM and associated subsystems are being reset, but at the same time, Nitro core is being kept in sane state (to allow external PCIe connected servers to continue to work). Without properly shutting down RoCE and freeing all associated resources, it results in the ARM core to hang immediately after the 'reboot' By always invoking 'bnxt_ulp_shutdown' in 'bnxt_shutdown', it fixes the above issue Fixes: 0efd2fc6 ("bnxt_en: Add a callback to inform RDMA driver during PCI shutdown.")

Since day one of XDP drivers had to remember to free the program on the remove path. This leads to code duplication and is error prone. Make the stack query the installed programs on unregister and if something is installed, remove the program. Freeing of program attached to XDP generic is moved from free_netdev() as well. Because the remove will now be called before notifiers are invoked, BPF offload state of the program will not get destroyed before uninstall.

This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

On 32-bit architectures, rtc_time_to_tm() returns incorrect results in 2038 or later, and do_gettimeofday() is broken for the same reason. This changes the code to use ktime_get_real_seconds() and time64_to_tm() instead, both of them are 2038-safe, and we can also get rid of the CONFIG_RTC_LIB dependency that way.

Recent IRQ coalescing clean up has removed a guard-rail for the max DMA buffer coalescing value. This is a 6-bit value and must not be 0. We already have a check for 0 but 64 is equivalent to 0 and will cause non-stop interrupts. Fix it by adding the proper check. Fixes: f8503969 ("bnxt_en: Refactor and simplify coalescing code.")

This restores the original behaviour before the block callbacks were introduced. Allow the drivers to do binding of block always, no matter if the NETIF_F_HW_TC feature is on or off.

This patch adds IPv4 vxlan encap/decap action support to TC-flower offload. For vxlan encap, the driver maintains a tunnel encap hash-table. When a new flow with a tunnel encap action arrives, this table is looked up; if an encap entry exists, it uses the already programmed encap_record_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new encap node is added and the L2 header fields are queried via a route lookup. hwrm_cfa_encap_record_alloc cmd is used to create a new encap record and the encap_record_handle is used as the tunnel_handle while adding the flow. For vxlan decap, the driver maintains a tunnel decap hash-table. When a new flow with a tunnel decap action arrives, this table is looked up; if a decap entry exists, it uses the already programmed decap_filter_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new decap node is added and a decap_filter_handle is alloc'd via the hwrm_cfa_decap_filter_alloc cmd. This handle is used as the tunnel_handle while adding the flow. The code to issue the HWRM FW cmds is introduced in a follow-up patch.

The mapping of the ethtool coalescing parameters to hardware parameters is now done in bnxt_hwrm_set_coal_params(). The same function can handle both RX and TX settings. The code is now more clear. Some adjustments have been made to get better hardware settings. The coal_frames setting is now accurately set in hardware. The max_timer is set to coal_ticks value.

The current IRQ coalescing logic is a little messy. The ethtool parameters are mapped to hardware parameters in a way that is difficult to understand. The first step is to better organize the parameters by adding the new structure bnxt_coal. The structure is used by both the RX and TX sets of coalescing parameters. Adjust the default coal_ticks to 14 us and 28 us for RX and TX. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
