[PATCH 06/14] docs: security-bugs: do not send archives or binary attachments

[Willy Tarreau]

Many reports still come with zip files or other archives attached, which
are a pain to deal with, may be blocked by filtering on some maintainers'
end, and that also encourage recipients to adopt risky practices of
opening binary files. The doc only used to say to avoid attachments
"where possible".

Let's clarify that archives, binary files and documents are never
acceptable, that large reproducers should be attached as plain text
source files, and that scripts generating the required files (e.g. file
system images) are a better solution.

 Please send **plain text** emails without attachments where possible.
 It is much harder to have a context-quoted discussion about a complex
-issue if all the details are hidden away in attachments.  Think of it like a
+issue if all the details are hidden away in attachments. Archives (zip, tar,

+reproducer is too large to be placed in the message, attach its source files

 list reproduction steps, all in plain text, then provide a proposed fix as
