Subject: [PATCH RESEND] um,ethertap: use strncpy
Date: Tue, 20 Jan 2015 12:11:12 +0000 [thread overview]
Message-ID: <20150120121100.28406.95201.stgit@localhost.localdomain> (raw)
I can't prove the case pointed out in
https://bugzilla.kernel.org/show_bug.cgi?id=82341
is correct so let us play safe.
