Description Marcel Holtmann 2006-10-31 10:07:11 UTC
From James Morris:

There's a bug in the seqfile handling for /proc/net/ip6_flowlabel, where, after
finding a flowlabel, the code will loop forever not finding any further
flowlabels, first traversing the rest of the hash bucket then just looping. This
bug can cause lockups and oopses, and is trivially invoked by an unpriveleged user.
