In order to query tm info of nodes, priority and qset for debugging, adds three debugfs files tm_nodes, tm_priority and tm_qset in newly created tm directory. Unlike previous debugfs commands, these three files just support read ops, so they only support to use cat command to dump their info. The new tm file style is acccording to suggestion from Jakub Kicinski's opinion as link https://lkml.org/lkml/2020/9/29/2101.

Pointers to receive-buffer packets sent by Hyper-V are used within the guest VM. Hyper-V can send packets with erroneous values or modify packet fields after they are processed by the guest. To defend against these scenarios, copy (sections of) the incoming packet after validating their length and offset fields in netvsc_filter_receive(). In this way, the packet can no longer be modified by the host.

Stop maintaining the skb_send_q list for TRANS_HIPER sockets. Not only is it extra overhead, but keeping around a list of skb clones means that we later also have to match the ->sk_txnotify() calls against these clones and free them accordingly. The current matching logic (comparing the skbs' shinfo location) is frustratingly fragile, and breaks if the skb's head is mangled in any sort of way while passing from dev_queue_xmit() to the device's HW queue. Also adjust the interface for ->sk_txnotify(), to make clear that we don't actually care about any skb internals.

As part of the TX queue selection for af_iucv skbs, qeth_l3_get_cast_type_rcu() ends up calling qeth_get_ether_cast_type(). Which is rather fragile, since such skbs don't have a proper ETH header and we rely on it being zeroed out in the right places. Add a separate case for ETH_P_AF_IUCV instead that does the right thing. When later building the HW header for such skbs, don't hard-code the cast type but follow the same path as for other protocol types. Here the cast type should naturally come from the skb's queue mapping.

The only time we transfer data (rather than issuing a command) out of the AP->command TX endpoint is when we're clearing the hardware pipeline. All that's needed is a "small" data buffer, and its contents aren't even important. For convenience, we just transfer a command structure in this case (it's already mapped for DMA). The TRE is added to a transaction using ipa_cmd_ip_tag_status_add(), but we ignore the size value provided to that function. So just get rid of the size argument.

There are times, such as when the modem crashes, when we issue commands to clear the IPA hardware pipeline. These commands include a data transfer command that delivers a small packet directly to the default (AP<-LAN RX) endpoint. The places that do this wait for the transactions that contain these commands to complete, but the pipeline can't be assumed clear until the sent packet has been *received*. The small transfer will be delivered with a status structure, and that status will indicate its tag is valid. This is the only place we send a tagged packet, so we use the tag to determine when the pipeline clear packet has arrived. Add a completion to the IPA structure to to be used to signal the receipt of a pipeline clear packet. Create a new function ipa_cmd_pipeline_clear_wait() that will wait for that completion. Reinitialize the completion whenever pipeline clear commands are added to a transaction. Extend ipa_endpoint_status_tag() to check whether a packet whose status contains a valid tag was sent from the AP->command TX endpoint, and if so, signal the new IPA completion. Have all callers of ipa_cmd_pipeline_clear_add() wait for the pipeline clear indication after the transaction that clears the pipeline has completed.

There is a set of functions and symbols related to performing "tag_process" immediate commands to clear the IPA pipeline. The name is related to one of the commands issued when doing this, but it doesn't really convey the overall purpose of taking this action. The purpose is to take some steps to "clear out" the hardware pipeline, and to wait until that process completes, to ensure the IPA hardware is in a well-defined state.

The workaround for VSOL V2801F brand based GPON SFP modules added in commit 0d035bed ("net: sfp: VSOL V2801F / CarlitoxxPro CPGOS03-0490 v2.0 workaround") works only for IDs added explicitly to the list. Since there are rebranded modules where OEM vendors put different strings into the vendor name field, we cannot base workaround on IDs only. Moreover the issue which the above mentioned commit tried to work around is generic not only to VSOL based modules, but rather to all GPON modules based on Realtek RTL8672 and RTL9601C chips. These include at least the following GPON modules: * V-SOL V2801F * C-Data FD511GX-RM0 * OPTON GP801R * BAUDCOM BD-1234-SFM * CPGOS03-0490 v2.0 * Ubiquiti U-Fiber Instant * EXOT EGS1 These Realtek chips have broken EEPROM emulator which for N-byte read operation returns just the first byte of EEPROM data, followed by N-1 zeros. Introduce a new function, sfp_id_needs_byte_io(), which detects SFP modules with broken EEPROM emulator based on N-1 zeros and switch to 1 byte EEPROM reading operation. Function sfp_i2c_read() now always uses single byte reading when it is required and when function sfp_hwmon_probe() detects single byte access, it disables registration of hwmon device, because in this case we cannot reliably and atomically read 2 bytes as is required by the standard for retrieving values from diagnostic area. (These Realtek chips are broken in a way that violates SFP standards for diagnostic interface. Kernel in this case simply cannot do anything less of skipping registration of the hwmon interface.) This patch fixes reading of EEPROM content from SFP modules based on Realtek RTL8672 and RTL9601C chips. Diagnostic interface of EEPROM stays broken and cannot be fixed.

The purpose of the delayed work in the SPAN module is to potentially update the destination port and various encapsulation parameters of SPAN agents that point to a VLAN device or a GRE tap. The destination port can change following the insertion of a new route, for example. SPAN agents that point to a physical port or the CPU port are static and never change throughout the lifetime of the SPAN agent. Therefore, skip over them in the delayed work. This fixes an issue where the delayed work overwrites the policer that was set on a SPAN agent pointing to the CPU. Modifying the delayed work to inherit the original policer configuration is error-prone, as the same will be needed for any new parameter.
