Hi,

I am an Outreachy 2015 Applicant. I have a background in C, C++ and shell
scripting. I am also familiar with concepts of Operating Systems.

I would like to contribute to the Xen project and it would be very helpful
if I could get some help getting started.

I have gone through the beginner's guide [0] and cloned the git repository
[1].

To complete your application, you have to pick up to make a small
contribution to Xen [1].

We don't seem to have many small task on bugs.xenproject.org/xen, so
I've CCed a few people who may know if we have small coverity issue to fix.

I had a quick glance at coverity and found:

CID1055958: use of mkstemp in libxl_vncviewer_exec without first setting a
sensible umask. 

CID1311511: lack of error checking on the result of xc_dom_allocate in init
-xenstore-domain.c.

CID1223209: lack of error checking when calling
libxl_cpupool_qualifier_to_cpupoolid in initiate_domain_create (part of
libxl).

CID1090350: lack of error checking when calling xc_domain_get_guest_width
in xc_cpuid_pv_policy.

Fixing some of those would be useful I think.

Ian.

I would like to fix the above coverity issues. I have cloned the git repo
[1]. I have also requested for access to the Xen project.
I am new to open source, so I am not familiar with the procedure. Is there
anything else that I need to do / know to get started?

Thanks alot.

You only need to fix a single coverity issue in your small contribution.

A list of useful wiki pages to read:

Note that you don't need access to coverity scan in order to fix the
bugs listed in this email. Coverity won't give you more insight than
what is already available here.

If you think the one-liner description is not enough, please let us
know. But I would encourage you read code first, and send separate email
to xen-devel for a specific bug and questions related to it.
