REPORTING-BUGS is pretty disorganized. Bug reporters are likely to be in a frustrated, stressed frame of mind, so introduce methodical step-by-step directions for how to report bugs. Use titles so people can skim it if necessary. Slight changes in procedures: 1. Encourage people to report bugs to maintainers and sub-system mailing lists, not LKML at first. I've seen way too many people get lost in the noise because they didn't Cc the maintainer or proper mailing list. 2. Link to bugzilla.kernel.org, and let people know that some maintainers prefer bugs filed there vs. the mailing lists. (Perhaps we need an entry in MAINTAINERS for which is preferred?) 3. If someone doesn't know where to report a bug, encourage them to both file a bugzilla entry and email LKML. Their report is less likely to get lost if there's a bugzilla entry. Preserve text about reporting security bugs, and get_maintainer.pl. More will be added/modified in upcoming patches. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

Identify the problematic subsystem
|
|
----------------------------------
|
|
|
|
Identifying which part of the Linux kernel might be causing your issue
|
|
increases your chances of getting your bug fixed. Simply posting to the
|
|
generic linux-kernel mailing list (LKML) may cause your bug report to be
|
|
lost in the noise of a mailing list that gets 1000+ emails a day.
|
|
|
|
Instead, try to figure out which kernel subsystem is causing the issue,
|
|
and email that subsystem's maintainer and mailing list. If the subsystem
|
|
maintainer doesn't answer, then expand your scope to mailing lists like
|
|
LKML.
|
|
|
|
|
|
Identify who to notify
|
|
----------------------
|
|
|
|
Once you know the subsystem that is causing the issue, you should send a
|
|
bug report. Some maintainers prefer bugs to be reported via bugzilla
|
|
(https://bugzilla.kernel.org), while others prefer that bugs be reported
|
|
via the subsystem mailing list.
|
|
|
|
To find out where to send an emailed bug report, find your subsystem or
|
|
device driver in the MAINTAINERS file. Search in the file for relevant
|
|
entries, and send your bug report to the person(s) listed in the "M:"
|
|
lines, making sure to Cc the mailing list(s) in the "L:" lines. When the
|
|
maintainer replies to you, make sure to 'Reply-all' in order to keep the
|
|
public mailing list(s) in the email thread.
|
|
|
|
If you know which driver is causing issues, you can pass one of the driver
|
|
files to the get_maintainer.pl script:
|
|
perl scripts/get_maintainer.pl -f <filename>
|
|
|
|
If it is a security bug, please copy the Security Contact listed in the
|
|
MAINTAINERS file. They can help coordinate bugfix and disclosure. See
|
|
Documentation/SecurityBugs for more information.
|
|
|
|
If you can't figure out which subsystem caused the issue, you should file
|
|
a bug in kernel.org bugzilla and send email to
|
|
linux-kernel@vger.kernel.org, referencing the bugzilla URL. (For more
|
|
information on the linux-kernel mailing list see
|
|
http://www.tux.org/lkml/).

What follows is a suggested procedure for reporting Linux bugs. You aren't
|
|
obliged to use the bug reporting format, it is provided as a guide to the
|
|
kind of information that can be useful to developers - no more.
|
|
|
|
If the failure includes an "OOPS:" type message in your log or on screen
|
|
please read "Documentation/oops-tracing.txt" before posting your bug
|
|
report. This explains what you should do with the "Oops" information to
|
|
make it useful to the recipient.
|
|
|
|
If it occurs repeatably try and describe how to recreate it. That is worth
|
|
even more than the oops itself.
|
|
|
|
This is a suggested format for a bug report sent to the Linux kernel mailing
|
|
list. Having a standardized bug report form makes it easier for you not to
|
|
overlook things, and easier for the developers to find the pieces of
|
|
information they're really interested in. Don't feel you have to follow it.
|
|
|
|
First run the ver_linux script included as scripts/ver_linux, which
|
|
reports the version of some important subsystems. Run this script with
|
|
the command "sh scripts/ver_linux".
|
|
|
|
Use that information to fill in all fields of the bug report form, and
|
|
post it to the mailing list with a subject of "PROBLEM: <one line
|
|
summary from [1.]>" for easy identification by the developers.
|
|
|
|
[1.] One line summary of the problem:
|
|
[2.] Full description of the problem/report:
|
|
[3.] Keywords (i.e., modules, networking, kernel):
|
|
[4.] Kernel information
|
|
[4.1.] Kernel version (from /proc/version):
|
|
[4.2.] Kernel .config file:
|
|
[5.] Most recent kernel version which did not have the bug:
|
|
[6.] Output of Oops.. message (if applicable) with symbolic information
|
|
resolved (see Documentation/oops-tracing.txt)
|
|
[7.] A small shell script or example program which triggers the
|
|
problem (if possible)
|
|
[8.] Environment
|
|
[8.1.] Software (add the output of the ver_linux script here)
|
|
[8.2.] Processor information (from /proc/cpuinfo):
|
|
[8.3.] Module information (from /proc/modules):
|
|
[8.4.] Loaded driver and hardware information (/proc/ioports, /proc/iomem)
|
|
[8.5.] PCI information ('lspci -vvv' as root)
|
|
[8.6.] SCSI information (from /proc/scsi/scsi)
|
|
[8.7.] Other information that might be relevant to the problem
|
|
(please look in /proc and include all information that you
|
|
think to be relevant):
