mainline inclusion from mainline-v5.15 commit 0251d196 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4I7P7 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0251d196b0e1 ---------------------------------------------------------------------- Currently, if there is a reset event triggered by RAS during device in initialization process, driver may run reset process concurrently with initialization process. In this case, it may cause problem. For example, the RSS indirection table may has not been alloc memory in initialization process yet, but it is used in reset process, it will cause a call trace like this: [61228.744836] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 ...

As driver gets register number from firmware to calculate desc number to query mac statistics, it needs to set mac statistics extended enable bit in firmware command 0x701A to tell firmware that driver supports extended mac statistics, otherwise firmware only returns register number of version V1. As pause/pfc durations are not supported by hardware of old version, they should not been shown in command "ethtool -S ethX" in this case, so add checking max register number of each mac statistic in their version. If the max register number of one mac statistic is greater than register number got from firmware, it means hardware does not support this mac statistic, so ignore this statistic when get string and data of mac statistic.

There is a problem that if the register number queried from firmware is larger than data number of struct mac_stats, it will cause a copy overflow. So if the firmware adds more mac statistics in later version, it is not compatible with driver of old version. To fix this problem, the number of copied data needs to be used the minimum value between the register number queried from firmware and data number of struct mac_stats. The first descriptor has three data and there is one reserved, to optimize the copy process, add this reserverd data to struct mac_stats.

Now the allocation retry is added, it is unnecessary to do the rx page allocation at the end of rx cleaning, so remove it. And reset the unused_count to zero after calling hns3_nic_alloc_rx_buffers() to avoid calling hns3_nic_alloc_rx_buffers() repeatedly under memory pressure.

That's mean if the config parameters in firmware is zero, driver will divide the whole unicast MAC address space equally to 8 PFs. However, in this case, the unicast MAC address space will be wasted a lot when the hardware actually has less then 8 PFs. And in the other hand, if one PF has much more VFs than other PFs, then each function of this PF will has much less address space than other PFs. In order to ameliorate the above two situations, introduce the third way of unicast MAC address space assignment: firmware divides the whole unicast MAC address space equally to functions of all PFs, and calculates the space size of each PF according to its function number. PF queries the space size by the querying device specification command when in initialization process. The third way assignment is lower priority than specified by config parameters, only if the config parameters is zero can be used, and if firmware does not support the third way assignment, then driver still divides the whole unicast MAC address space equally to 8 PFs.

stable inclusion from stable-5.10.77 commit e81bed557fe7dedff78ac1a7c098f4375b4981e2 bugzilla: 185677 https://gitee.com/openeuler/kernel/issues/I4IAP7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e81bed557fe7dedff78ac1a7c098f4375b4981e2 -------------------------------- commit 75963576 upstream. When the driver fails to allocate a new Rx buffer, it passes an empty Rx descriptor (contains zero address and size) to the device and marks it as invalid by setting the skb pointer in the descriptor's metadata to NULL. After processing enough Rx descriptors, the driver will try to process the invalid descriptor, but will return immediately seeing that the skb pointer is NULL. Since the driver no longer passes new Rx descriptors to the device, the Rx queue will eventually become full and the device will start to drop packets. Fix this by recycling the received packet if allocation of the new packet failed. This means that allocation is no longer performed at the end of the Rx routine, but at the start, before tearing down the DMA mapping of the received packet. Remove the comment about the descriptor being zeroed as it is no longer correct. This is OK because we either use the descriptor as-is (when recycling) or overwrite its address and size fields with that of the newly allocated Rx buffer. The issue was discovered when a process ("perf") consumed too much memory and put the system under memory pressure. It can be reproduced by injecting slab allocation failures [1]. After the fix, the Rx queue no longer comes to a halt.

Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

When SRIOV is enable and hclge.ko is removed, HW device is unloaded but VF still exists, PF will not reply VF mbx messages, and cause errors. This patch fix it by disable SRIOV before remove hclge.ko.

It checks the value of hdev->reset_pending to determine whether to exit the loop. However, the value of hdev->reset_pending may also be assigned by the interrupt function hclgevf_misc_irq_handle(), which may cause the loop fail to exit and keep occupying the workqueue. This loop is not necessary, so remove it and the workqueue will be rescheduled if the reset needs to be retried or a new reset occurs.

In this case, this tc may occupy all the tx bandwidth if it has huge traffic, so it violates the purpose of the user setting. To fix this problem, limit the ets dwrr bandwidth must greater than 0.
