Samuel Mendoza-Jonas 0795fb2021 net/ncsi: Stop monitor if channel times out or is inactive ncsi_channel_monitor() misses stopping the channel monitor in several places that it should, causing a WARN_ON_ONCE() to trigger when the monitor is re-started later, eg: [ 459.040000] WARNING: CPU: 0 PID: 1093 at net/ncsi/ncsi-manage.c:269 ncsi_start_channel_monitor+0x7c/0x90 [ 459.040000] CPU: 0 PID: 1093 Comm: kworker/0:3 Not tainted 4.10.17-gaca2fdd #140 [ 459.040000] Hardware name: ASpeed SoC [ 459.040000] Workqueue: events ncsi_dev_work [ 459.040000] [<80010094>] (unwind_backtrace) from [<8000d950>] (show_stack+0x20/0x24) [ 459.040000] [<8000d950>] (show_stack) from [<801dbf70>] (dump_stack+0x20/0x28) [ 459.040000] [<801dbf70>] (dump_stack) from [<80018d7c>] (__warn+0xe0/0x108) [ 459.040000] [<80018d7c>] (__warn) from [<80018e70>] (warn_slowpath_null+0x30/0x38) [ 459.040000] [<80018e70>] (warn_slowpath_null) from [<803f6a08>] (ncsi_start_channel_monitor+0x7c/0x90) [ 459.040000] [<803f6a08>] (ncsi_start_channel_monitor) from [<803f7664>] (ncsi_configure_channel+0xdc/0x5fc) [ 459.040000] [<803f7664>] (ncsi_configure_channel) from [<803f8160>] (ncsi_dev_work+0xac/0x474) [ 459.040000] [<803f8160>] (ncsi_dev_work) from [<8002d244>] (process_one_work+0x1e0/0x450) [ 459.040000] [<8002d244>] (process_one_work) from [<8002d510>] (worker_thread+0x5c/0x570) [ 459.040000] [<8002d510>] (worker_thread) from [<80033614>] (kthread+0x124/0x164) [ 459.040000] [<80033614>] (kthread) from [<8000a5e8>] (ret_from_fork+0x14/0x2c) This also updates the monitor instead of just returning if ncsi_xmit_cmd() fails to send the get-link-status command so that the monitor properly times out.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
