This patch uses common cmdq resource allocate/free/query APIs to replace the old APIs in PF cmdq module and deletes the old cmdq resource APIs. Still we kept hclge_cmd_setup_basic_desc name as a seam API to avoid too many meaningless replacement. Signed-off-by:

The PF and VF cmdq module resource allocate/free/query APIs are almost the same espect the suffixes of API names. These same implementations bring double development and bugfix work. This patch creates common cmdq resource allocate/free/query APIs called by PF and VF cmdq init/uninit APIs. The next patch will use the new unified APIs to replace init/uninit APIs. Signed-off-by:

This patch firstly uses new hardware description struct hclge_comm_hw as child member of hclgevf_hw and deletes the old hardware description child members. All the hclgevf_hw variables used in VF module is modified according to the new hclgevf_hw. Secondly hclgevf_cmd_send is refactored to use hclge_comm_cmd_send APIs. The old functions called by hclgevf_cmd_send are all deleted. Still we kept hclgevf_cmd_send to avoid too many meaningless modifications. Signed-off-by:

This patch create new set of unified hclge_comm_cmd_send APIs for PF and VF cmdq module. Subfunctions called by hclge_comm_cmd_send are also created include cmdq result check, cmdq return code conversion and ring space opertaion APIs. These new common cmdq APIs will be used to replace the old PF and VF cmdq APIs in next patches. Signed-off-by:

Currently PF and VF cmdq APIs use struct hclge(vf)_hw to describe cmdq hardware information needed by hclge(vf)_cmd_send. There are a little differences between its child struct hclge_cmq_ring and hclgevf_cmq_ring. It is redundent to use two sets of structures to support same functions. So this patch creates new set of common cmdq hardware description structures(hclge_comm_hw) to unify PF and VF cmdq functions. The struct hclge_desc is still kept to avoid too many meaningless replacement. These new structures will be used to unify hclge(vf)_hw structures in PF and VF cmdq APIs in next patches.

Currently we plan to refactor PF and VF cmdq module. A new file folder hns3_common will be created to store new common APIs used by PF and VF cmdq module. Thus the PF and VF compilation process will both depends on the hns3_common. This may cause parallel building problems if we add a new makefile building unit. So this patch combined the PF and VF makefile scripts to the top level makefile to support the new hns3_common which will be created in the next patch. Signed-off-by:

1. Define more regs. Some switches (e.g. BCM4908) have up to 6 regs. 2. Add helper for handling non-lineral port <-> reg mappings. 3. Add support for 12 B LED reg blocks on BCM4908 (different layout) Complete support for LEDs setup will be implemented once Linux receives a proper design & implementation for "hardware" LEDs.

strlcpy is marked as deprecated in Documentation/process/deprecated.rst, and there is no functional difference when the caller expects truncation (when not checking the return value). strscpy is relatively better as it also avoids scanning the whole source string.

Add support to enable flow-director filter when multiple TCs are configured. Flow director filter can be configured using ethtool (--config-ntuple option). When multiple TCs are configured, each TC is mapped to an unique HW VSI. So VSI corresponding to queue used in filter is identified and flow director context is updated with correct VSI while configuring ntuple filter in HW. Signed-off-by:

queue Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2021-12-29 Ruud Bos says: The igb driver provides support for PEROUT and EXTTS pin functions that allow adapter external use of timing signals. At Hottinger Bruel & Kjaer we are using the PEROUT function to feed a PTP corrected 1pps signal into an FPGA as cross system synchronized time source. Support for the PEROUT and EXTTS SDP functions is currently limited to i210/i211 based adapters. This patch series enables these functions also for 82580/i354/i350 based ones. Because the time registers of these adapters do not have the nice split in second rollovers as the i210 has, the implementation is slightly more complex compared to the i210 implementation. The PEROUT function has been successfully tested on an i350 based ethernet adapter. Using the following user space code excerpt, the driver outputs a PTP corrected 1pps signal on the SDP0 pin of an i350: struct ptp_pin_desc desc; memset(&desc, 0, sizeof(desc)); desc.index = 0; desc.func = PTP_PF_PEROUT; desc.chan = 0; if (ioctl(fd, PTP_PIN_SETFUNC, &desc) == 0) { struct timespec ts; if (clock_gettime(clkid, &ts) == 0) { struct ptp_perout_request rq; memset(&rq, 0, sizeof(rq)); rq.index = 0; rq.start.sec = ts.tv_sec + 1; rq.start.nsec = 500000000; rq.period.sec = 1; rq.period.nsec = 0; if (ioctl(fd, PTP_PEROUT_REQUEST, &rq) == 0) { /* 1pps signal is now available on SDP0 */ } } } The added EXTTS function has not been tested. However, looking at the data sheets, the layout of the registers involved match the i210 exactly except for the time registers mentioned before. Hence the almost identical implementation. --- Note: I made changes to fix RCT and checkpatch messages regarding unnecessary parenthesis. ==================== Acked-by:Richard Cochran <richardcochran@gmail.com> Signed-off-by:

TRAP packets, that has to be routed (if packet has router's destination MAC address).

Initial implementation of notification handlers. For now this is just stub. So that we can move forward and add prestera_router_hw's objects manipulations. We support several addresses on interface. We just have nothing to do for second address, because rif is already enabled on this interface, after first one. Co-developed-by:

Add prestera_router_hw.c. This file contains functions, which track HW objects relations and links. This include implicity creation of objects, that needed by requested one and implicity removing of objects, which reference counter is became zero. We need this layer, because kernel callbacks not always mapped to creation of single HW object. So let it be two different layers - one for subscribing and parsing kernel structures, and another (prestera_router_hw.c) for HW objects relations tracking. There is two types of objects on router_hw layer: - Explicit objects (rif_entry) : created by higher layer. - Implicit objects (vr) : created on demand by explicit objects. Co-developed-by:

As we can see from the comment of the nla_put() that it could return -EMSGSIZE if the tailroom of the skb is insufficient. Therefore, it should be better to check the return value of the nla_put_u32 and return the error code if error accurs. Also, there are many other functions have the same problem, and if this patch is correct, I will commit a new version to fix all.

The ipv4_mib_exit_net is called before tcp_sk_exit_batch when a net namespace is destroyed since tcp_sk_ops is registered befrore ipv4_mib_ops, which means tcp_sk_ops is in the front of ipv4_mib_ops in the list of pernet_list. There will be a use-after-free on net->mib.net_statistics in tw_timer_handler after ipv4_mib_exit_net if there are some inflight time-wait timers. This bug is not introduced by commit f2bf415c ("mib: add net to NET_ADD_STATS_BH") since the net_statistics is a global variable instead of dynamic allocation and freeing. Actually, commit 61a7e260 ("mib: put net statistics on struct net") introduces the bug since it put net statistics on struct net and free it when net namespace is destroyed. Moving init_ipv4_mibs() to the front of tcp_init() to fix this bug and replace pr_crit() with panic() since continuing is meaningless when init_ipv4_mibs() fails.
