[PATCH V3 net 0/7] There are some bugfix for the HNS3 ethernet driver

[Jijie Shao]

There's a series of bugfix that's been accepted:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=d80a3091308491455b6501b1c4b68698c4a7cd24

However, The series is making the driver poke into IOMMU internals instead of
implementing appropriate IOMMU workarounds. After discussion, the series was reverted:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=249cfa318fb1b77eb726c2ff4f74c9685f04e568

But only two patches are related to the IOMMU.
Other patches involve only the modification of the driver.
This series resends other patches.

[PATCH V3 net 1/7] net: hns3: fixed reset failure issues caused by the incorrect reset type

[Jijie Shao]

From: Hao Lan <lanhao@huawei.com>

When a reset type that is not supported by the driver is input, a reset
pending flag bit of the HNAE3_NONE_RESET type is generated in
reset_pending. The driver does not have a mechanism to clear this type
of error. As a result, the driver considers that the reset is not
complete. This patch provides a mechanism to clear the
HNAE3_NONE_RESET flag and the parameter of
hnae3_ae_ops.set_default_reset_request is verified.

The error message:
hns3 0000:39:01.0: cmd failed -16
hns3 0000:39:01.0: hclge device re-init failed, VF is disabled!
hns3 0000:39:01.0: failed to reset VF stack
hns3 0000:39:01.0: failed to reset VF(4)
hns3 0000:39:01.0: prepare reset(2) wait done
hns3 0000:39:01.0 eth4: already uninitialized

Use the crash tool to view struct hclgevf_dev:
struct hclgevf_dev {
...
	default_reset_request = 0x20,
	reset_level = HNAE3_NONE_RESET,
	reset_pending = 0x100,
	reset_type = HNAE3_NONE_RESET,
...
};

[PATCH V3 net 2/7] net: hns3: fix missing features due to dev->features configuration too early

[Jijie Shao]

From: Hao Lan <lanhao@huawei.com>

Currently, the netdev->features is configured in hns3_nic_set_features.
As a result, __netdev_update_features considers that there is no feature
difference, and the procedures of the real features are missing.

[PATCH V3 net 3/7] net: hns3: Resolved the issue that the debugfs query result is inconsistent.

[Jijie Shao]

From: Hao Lan <lanhao@huawei.com>

This patch modifies the implementation of debugfs:

When the user process stops unexpectedly, not all data of the file system
is read. In this case, the save_buf pointer is not released. When the
user process is called next time, save_buf is used to copy the cached
data to the user space. As a result, the queried data is stale.

To solve this problem, this patch implements .open() and .release() handler
for debugfs file_operations. moving allocation buffer and execution
of the cmd to the .open() handler and freeing in to the .release() handler.
Allocate separate buffer for each reader and associate the buffer
with the file pointer.
When different user read processes no longer share the buffer,
the stale data problem is fixed.

[PATCH V3 net 4/7] net: hns3: don't auto enable misc vector

[Jijie Shao]

From: Jian Shen <shenjian15@huawei.com>

Currently, there is a time window between misc irq enabled
and service task inited. If an interrupte is reported at
this time, it will cause warning like below:

[PATCH V3 net 5/7] net: hns3: initialize reset_timer before hclgevf_misc_irq_init()

[Jijie Shao]

From: Jian Shen <shenjian15@huawei.com>

Currently the misc irq is initialized before reset_timer setup. But
it will access the reset_timer in the irq handler. So initialize
the reset_timer earlier.

[PATCH V3 net 6/7] net: hns3: fixed hclge_fetch_pf_reg accesses bar space out of bounds issue

[Jijie Shao]

From: Hao Lan <lanhao@huawei.com>

The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs
1024-1279 are in different BAR space addresses. However,
hclge_fetch_pf_reg does not distinguish the tqp space information when
reading the tqp space information. When the number of TQPs is greater
than 1024, access bar space overwriting occurs.
The problem of different segments has been considered during the
initialization of tqp.io_base. Therefore, tqp.io_base is directly used
when the queue is read in hclge_fetch_pf_reg.

The error message:

Unable to handle kernel paging request at virtual address ffff800037200000

[PATCH V3 net 7/7] net: hns3: fix kernel crash when 1588 is sent on HIP08 devices

Currently, HIP08 devices does not register the ptp devices, so the
hdev->ptp is NULL. But the tx process would still try to set hardware time
stamp info with SKBTX_HW_TSTAMP flag and cause a kernel crash.
